(Cl. 221-23) This invention relates to a device for dispensing canned ?uids and relates more particularly to a device for opening sealed containers or cans and for pouring or dispensing the contents therefrom. It is a general object of this invention to provide a simple, practical and improved device for open ing cans and for facilitating the pouring or drain ing of the contents from the cans. Lubricating oils, etc., are being marketed in 10 sealed cans to prevent them from being adulter ated or substituted for by inferior products. Various forms of can opening devices have been introduced for opening the cans of lubricating oils and for facilitating the dispensing of their contents. The can opening devices of this char acter now in use perforate or form openings in either the upper or lower ends of the cans and leave the other parts of the cans whole and un mutilated. Unscrupulous dealers and others have removed the mutilated ends of cans opened by such devices and after re?lling the cans with cheap or inferior products have replaced the can ends and again marketed the re?lled cans, repre senting that they contained the products de scribed by the original labels. An object of this invention is to provide a device for opening cans that cuts openings in both and end wall and- a side wall of a can to posi tively render the can un?t for re?lling or re-use. Another object of the invention is to provide a device that cuts a large unobstructed pouring opening in an end of a can upon being pressed or forced on the can, then forms an effective spout for pouring the contents from the can,- and that 33 operates to automatically cut a long mutilating slit or opening in the side wall of the can upon being disengaged from the can. Another object of theiinvention is to provide a can opening and dispensing device of the char 40 acter mentioned including a tubular spout shaped and formed to constitute a convenient handle for facilitating the handling and operating of the device, said spout being adapted to being in serted in the oil ?lling pipe of an engine, or the - 5 like, to support the device and can thereon as the contents of the can are being drained, into the crank case of the engine. The spout of the de vice of this invention is'longitudinally curved to comfortably ?t the hand and is provided with finger engaging ribs to resemble what is com~ monly known as a pistol grip. Another object of the invention is to provide a can opening device of the character mentioned that includes a simple and particularly effective 55 cutter for cutting the pouring or dispensing opening in the can, said cutter being ?rmly braced and held rigid with respect to the. spout and guide and being attached to the spout so that it may be easily removed for replacement. Another object of the invention is to provide Ol a device of the character mentioned embodying a novel and improved means for punching or forming an opening in an end of a can for ad mitting atmospheric pressure to facilitate or ac celerate the pouring of the contents from the can. 10 It is another object of the invention to provide a can opener and dispensing device of the char acter mentioned that tightly seals with the wall of the can around the opening formed by the principal cutter to prevent the leakage of the 15 ?uid and prevent soiling of the can and device during the dispensing or pouring operation. Another object of the invention is to provide a device of the character mentioned thatembodies a novel mutilating cutter that is inoperative dur ing the forcing of the principal cutter through the end wall of the can to form the pouring open~ ing, that aids in dependably retaining the device on the can when the can is inverted to dispense its contents and that automatically cuts a long slit or opening in the side wall of the can when the device is removed from the emptied can. A further object of the invention is to provide an improved can opener and ?uid dispensing de vice that is simple and inexpensive and that com prises a simple integral .body member constitut ing a spout, a handle and a guide for guiding the cutter into the can wall. Other objects and features of the invention will be better and fully understood from the following detailed description of typical preferred forms of the invention, throughout which description ref erence may be had to the accompanying draw ings, in which: Fig. 1 is a side elevation of the device of this invention illustrating the punch cutting an air vent in the upper end of the can. Fig. 2 is an enlarged longitudinal detailed sectional view of the device after having been forced downwardly on the can to actuate the principal cutter through the upper wall of the can. Fig. 3 is a transverse detailed sectional view taken as indi cated by line 3-3 on Fig. 1. Fig. 4 is a frag mentary elevation view of the inner side or the device taken substantially as indicated by line 50 4-4 of Fig. 1. Fig. 5 is a fragmentary longi tudinal sectional view of the lower portion of the device showing the mutilating cutter in oper ation during the removal of the device from the can. Fig. 6 is a longitudinal detailed sectional 2,105,575 2 4 view of the device illustrating another type of can multilating cutter. Fig. 7 is a transverse detailed sectional view taken as indicated by line 'I-—‘I on Fig. 6. Fig. 8 is a view similiar to Fig. 6 illustrating still another form of mutilating cutter, and Fig. 9 is a transverse detailed sectional view taken as indicated by line 9—9 on Fig. '8. The form of the present invention illustrated in Figs. 1 to 5, inclusive, of the drawings, includes 10 generally, a body I0 comprising a spout and han dle A, and a guide B, a main or principal cutter II on the body In for forming a pouring opening in a'can C,‘ a means or cutter I2 on the guide B for mutilating the side wall W of the can and 15 means I3 for making an air inlet opening in the end E of the can. The body I0 carries the two cutters.“ and I2 and therefore constitutes a cutter support or cut ter supporting member. In the form of the in 20 vention being described the body I0 carries the means I3 and comprises two main parts, namely the handle and spout A and the guide B for guid ing the principal cutter II. The support or body III may be an integral casting of aluminum 25 or other suitable material. The spout and han dle A of the body is an elongate tubular part hav ing a longitudinal opening Ill. The central lon~ gitudinal axis of the spout A is inclined upwardly and outwardly considering the device in the posi 30 tion illustrated in Fig. 2 of the drawings. The _ spout A is proportioned to be readily inserted in the oil ?lling pipe or receiver of the crank case of an engine. It is an important feature of the invention that 35 the spout A is shaped and designed to constitute an effective and convenient handle. The com bined handle and spout A is preferably longitudi nally curved and generally cylindrical in its cross section. The inner side or surface of the spout A 40 that faces upwardly to some extent, due to the inclination and curvature of the spout, is prefer ably roughened or grooved so that the palm of the hand which engages this surface has less tend ency to slip. In the particular construction illus 45 trated in the drawings transverse or circumferen tially extending notches I5 are provided in the upper surface of the spout A. The grooves vor . notches IS in addition to bene?ting the opera ator’s grip of the spout prevents slipping or tilt ing of the spout A when it is inserted in the oil ?lling pipe or tube of an engine for the purpose of draining the oil from the can C. The outer surface of the spout A which faces downwar y and outwardly is engaged by the four ?n.» ‘ the user’s hand and is provided with three s 55 transverse I6 are longitudinally or circumferential spaced and ribs areIS. related The to be parallel while the lower end of the guide is pref» erably curved asillustrated in the drawings. The principal cutter II is adapted to be forced or driven through the end wall E of the can C to cut a large unobstructed opening through which the contents of the can may be drained when the can is tipped or inverted. The cutter II is at tached to the support or body II] to have its shank extend into the opening I4 of the spout A and to have its active portion exposed at the inner side of the guide B. The principal cutter II is sub stantially U-shaped in transverse cross section having spaced substantially parallel side parts I8 and a curved transverse part I9 joining or con necting the side parts I8. The outer or lower end of the cutter II is pointed to readily enter or perforate the can wall E. The longitudinal edges 20 of the side part I8 are inclined and converge toward a point ZI on the lower end of the trans verse part I9. The inclination of the edges 20 is increased adjacent the point 2I and the part I9 is inclined inwardly or away from the guide B adjacent the point 2| as clearly illustrated in Figs. 2 and 5 of the drawings. In accordance with the invention the edges 20 are ?at and sub 25 stantially normal to the adjacent side surfaces of the parts I8 and I9 so that their outer corners have an effective shearing action when the cutter is forced into the can wall E. Further, the flat normal edges 20 ?atly bear against the tab or 30 flap F cut by the cutter II to positively roll the ?ap back and leave the opening formed by the cutter entirely unobstructed. The cutter II is preferably inclined so that its transverse part I9 is‘ inclined downwardly and outwardly toward the inner side I‘! of the guide B. This inclination of the cutter II causes the side wall W and the bead X of the can to be pinched or gripped between the cutter part I9 and the guide B. - The gripping engagement of the cutter 40 II and the guide B with the wall of the can aids in detachably holding the device on the can when the can is handled and inverted during the drain ing of its contents. The point 2I of the cutter I I may be bevelled or sharpened at its inner side and is spaced from the guide B to enter the can wall E adjacent the bead X upon the device being pressed downwardly on the can. The guide B engages the exterior of the can to position the point 2! of the cutter, and as the cutter moves 50 downwardly the guide engages the can wall W to ‘aide the cutter and to cause the cutter to form unobstructed opening in the end of the side parts I 8 of the cutter project upwardly 55 li'l’O the spout opening I4 and bear against sub si’ "nadir flat parallel faces 22 at the mouth of the opening. This engagement of the cutter parts ill with the faces 22 prevents lateral movement or rocking of the cutter relative to the body Ill. 60 The transverse part I9 of the cutter seats against the wall of the opening I 4 and is slightly curved to follow the longitudinal curvature of the open received between the ?ngers of the hand insuring a firm positive grip on the spout. The guide B of the body It is provided to en 60 gage the side wall W of the can C to guide the principal cutter II to form an opening the end E that extends inwardly from the peripheral bead X of the can. The guide B is an elongate ing. The side parts I8 are cut away or cut back at 23 to allow the curved portion of the part I9 65 65 part projecting or continuing downwardly from [to enter the opening I4 for a considerable dis the outer lower end portion of the spout A. In the preferred form of the invention illustrated in tance. A bolt or screw 24 is arranged through the drawings the guide B is somewhat wider than openings in the spout A and the cutter part I9 the spout A. The inner side I‘! of the guide B is and a nut 25 is threaded on the bolt to attach the 70 cutter II to the body ID. 70 concave to properly slidably engage the cylindri A lip 26 is provided on the body III to project cal side wall W of the typical can C. It is to be understood that the guide B may be shaped to downwardly between the spaced side parts I8 of adapt the device for opening cans of various sizes the cutter II. The outer side of the lip 26 is and con?gurations. The opposite vertical edges inclined, being flush with the edges 20. The lip 26 enters the opening formed by the cutter II 75 ' of the guide B may be straight and substantially 75 2,105,575 and bears and seals against the ?ap F in the manner illustrated in Fig. 2 of the drawings. The side parts l8 of the cutter are ?ared outwardly adjacent their upper ends to receive the lip 26 and their ?ared portions provide inclined shoul ders 21. The shoulders 21 bear or wedge against the side walls of the opening formed in the can Wall E by the cutter to provide a ?uid tight seal about the cutter and to aid in retaining the cutter 10 in the opening. The upper side of the lip 26 forms a rest for theiuser’s thumb when he operates the device. Shoulders 28 are provided on the side parts l8 to bear against the edge of the body at the base of the lip 26. The shoulders 28 receive 3 of teeth 35, and joins the point or the outer end of the uppermost tooth. After the contents have been drained from the can C and it is desired to disengage the de vice from the can the device is pulled or moved upwardly to free it from the can. During the initial portion of this upward movement of the device relative to the can C the teeth 35 cooperate with the can wall W to cause the cutter I2 to pivot in a direction to force or project the abrupt 10 end of the" edge 36 through the wall W. A stop 31 is provided’on the cutter l2 to engage the outer surface of the guide B to limit pivoting of the cutter |2 in a position where the edge 36 projects 15 the downward thrusts transmitted from the body to the cutter II when the device is forced or downwardly and inwardly and extends through 15 the wall W of the can; This position of the cut pressed downwardly on the can C to force the cut ter || through the wall E. ter I2 is illustrated in Fig. 4 of the drawings. Suitable openings 29 are'provided in the side walls of the cutter || adjacent the shoulders 21 to permit the ?uid or oil to drain out from around the cutter when‘ the can is inverted to drain its contents through the spout A. With the cutter H in its fully actuated position the open during the detachment of the device from the can. 20 In practice it may be preferred to sharpen the edge 36 on one side only so that the can wall W is bent inwardly at one side of the cutter l2 and bent outwardly at the other side of the cutter l2, while thecutter forms the mutilating slit S. This formation of the cutting edge 36 makes the cut ter l2 particularly easy to operate.- The teeth 25 lugs 29 are adjacent the inner side of the can wall E and allow the free drainage of ?uid from around the cutter. An air~ vent or opening 9 is provided in the lip 26 to communicate with the passage l4 of the spout. The opening 9 is posi 30 tioned to be immediately outside of the can wall E when the cutter is in its fully operated posi tion and admits air to the passage | 4 and the in terior of the can to facilitate the pouring of the contents of the can. Depressions or recesses 30 35 are provided in the body It] around the shank of the cutter where it enters the opening l4 to re ceive and trap any liquid that may leak from around the cutter during the pouring of the con tents from the can C. In assembling the cutter H on the body |0 its shank is forced or pressed in the opening l4 so that the curved part I 9 is sprung into position in the opening l4. The bolt 24 and nut 25 holds the cutter against displace 45 ment. The lip‘26 tightly bears outwardly against 35 present or bear inwardly against the can wallv W when the device is in its operative position on the can to assist in holding the device against 30 displacement from the can. The cutter |2 does not perforate or cut through the wall W when the device is pressed on the can to form the prin cipal pouring opening and automatically cuts 35 The means l3 for making an air inlet opening ' ' to punch a comparative ly small hole in the upper end wall E of the can before the cutter H is forced or driven through the end of the can. The means l3 includes a longitudinally extending enlargement or rib 40 on the outer side of the guide B.

After the disengagement of the punch 42 from the can the device is positioned at a point substantially diametrically opposite the opening formed by the punch and the inner side i‘! of the guide is placed against the can wall W to position the point 2| of the principal cutter above 'or in engagement with the can wall E adjacent the bead the device. The cutter II is attached to the body I0 so that it may be readily replaced if de sired or found necessary. The cutter II is ?rmly and rigidly attached to the body and is effective ly braced but is adapted to bend or ?ex su?iciently X. The device is then driven or pressed down wardly to force the cutter ll through the wall E to form the ?uid discharging opening. The spout A in being in the form of a pistol grip handle as described above is adapted to be engaged and readily pressed downwardly by the operator to force the cutter ll through the end of the can. 15 The point 2| of the cutter ll enters the can wall E adjacent the bead X and as the downward movement of the cutter progresses the diverging and inclined edges 26 enlarge the opening. The outer corners of the edges 26 operate to shear ago through the can wall E while the edges ?atly bear against the flap ‘F causing it to be rolled back. This leaves a clean unobstructed opening in the wall E communicating with the interior of the U-shaped cutter I l. Upon the completion of the downward move ment of the cutter I l the lip 26 and the shoulders 21 enter and wedge in the opening tightly sealing about the cutter H and resisting disengagement of the device from the can. - g: Further, the can wall W is tightly held between the inclined cutter II and the guide B and is engaged by the teeth 35 of the cutter l2 to aid in preventing accidental disconnection of the device from the can. As the guide B moves downwardly at the exterior of the can' the teeth 35 slidably engage the wall W with out forming a slit therein and hold the cutter l2 in the position where the stop 34 bears against the ?at end of the plug 31. To drain or pour the contents from the can C the can is raised and tipped or inverted so that its contents pour from 40 the spout A. The spout A is formed and pro portioned to be readily inserted in the oil ?lling opening of the crank case of an engine and the ribs l6 and notches l5 operate to prevent tilting or slipping of the spout when the spout is sup porting the device and the can on the pipe. The liquid in the can C is free to quickly drain out through the spout opening M. The openings 29 permit the free and complete drainage of fluid from around the outer side of the cutter. The recess 30 receives and traps any slight leakage that may occur around the cutter and prevents the soiling of the exteriors of the can and spout A. After the can has been emptied the device may be easily disengaged or detached from the can. During the removal or detachment of the device from the can the teeth 35 engage the wall W and cause the cutter l2 to swing to a position where the pointed portion of the cutter enters thewall W and the cutting edge 36 faces upwardly. The cutting edge 36 operates to form a long slit S in the can wall W. The device can not be removed or disengaged from the can C without cutting the mutilating slit S in the side ' wall W which positively prevents the re-use of the can. In actual operation the bead X may pass the cutter I2 without being out. This is de sirable as it may be difficult to cut through the bead. The can opening and fluid dispensing device of this invention is articularly easy and con venient to use and pro 'des for the quick complete dispensing of ?uids f om sealed containers or cans. The spout A is sh ped and designed to con stitute a convenient ha dle for the operation of to allow the bead X of the can to pass between its lower end part and the guide B. The cutter I2 is mounted in a simple effective manner and does not materially complicate the construction. The stops 34 and 31 which engage or bear against external surfaces of the guide B do not necessi tate special machining of either the cutter or the guide. _ Figs. 6 and 7 of the drawings illustrate a" form of the invention involving a modi?ed type of‘ mutilating cutter Ila. The spout A, the guide B, the cutter lla and the punch 42» may be sub stantially identical with the corresponding ele ments in the previously described embodiment of the invention. The cutter Illa instead of being - pivoted as the cutter I2, is longitudinally shift able on the guide B to retract as the cutter H8 is forced into the can and to advance to its oper ative cutting position as the cutter He is with [(1 LI drawn from the can. The cutter l2a includes a flat plate-like base ' 66 and an active cutting part 6|. The base 66 of the cutter I28L is movable longitudinally in a recess 62 in the inner side of the guide B. The longitudinal walls or sides of the recess 62 are parallel and are slidably engaged by the opposite edges of the base 60. In accordance with the in vention thev inner wall 63 of the recess 62 is inclined downwardly and toward the inner side of the guide, considering the device positioned 35 as illustrated in Fig. 6 of the drawings. The upper portion of the recess 62 is su?iciently deep to receive the cutter l2a so that only the outer portion or point of the cutting part 6| projects from the inner surface of the guide B to en 40 gage the side of the Iran. The cutting part 6| is blade-like, being pro videdwith a downwardly and outwardly inclined cutting edge 64 on its upper side. The cutting edge 64 may be bevelled or inclined to one side 43 surface of the cutting part, as. illustrated in the drawings. 'The lower edge 65 is inclined up wardly and outwardly to join the cutting edge 64 at a point. A longitudinal slot 66 is provided in the part l9a of the cutter'lla to receive the 50 cutting part 6|. The cutting part 6| is adapted to move through the slot 66 with only slight clearance. . In employing the form of the invention illus trated in Figs. 6 and 7 of the drawings the cutter He is driven or pushed through an end wall of a can, being guided by the guide B to cut an opening immediately adjacent the side wall of the can. During the forcing of the cutter lla through the end of the can the head at the 60 peripheral edge of the can and the side wall of the can pass between the cutter I la and the guide B. As the cutter Ha moves downwardly the in clined lower edge 65 of the cutting part 6| en gages the peripheral bead of the can and the 65 cutter l2it is thus held stationary during the next phase of downward movement of the device. In this manner the cutter 12a is received in the up per portion of the recess 62 and the engagement of the edge 65 with the can causes the cutter 70 l2a to be held outwardly against the inclined wall 63. With the cutter I28L in‘ this retracted posi tion the cutting part 6| projects slightly from the inner side of the guide B to engage the side wall of the can. This engagement does not cause 2,105,575 perforation of the can wall when the can is opened by .the main cutter H8. After the con tents have been drained from the can through the spout A the device may be disengaged from the can by engaging the spout and pulling the cutter II“ and guide B from the can. During this disengagement of the device from the con 5 of the can the lower edge ‘H of the cutter B bends or ?exes the side wall of the can out wardly but may not perforate the wall of the can. Following the draining of the contents from the can the cutter llb may be withdrawn from the can to free the device for further use. Dur ing this removal of the cutter llb from the can tainer or can the contact of the point of the the side wall of the can is ?exed against the cutting part 6| with the can holds the cutter l2a roller '15 by the cutter I2b and holds the roller 10 against the longitudinal movement so that the against upward movement.
