(Cl. 221-23) My invention relates to improvements in can openers and dispensers, and it is an object of my improvements to supply a device of this class at once inexpensive, convenient in its uses 5 and suitable for operation in garages, ?lling stations, or elsewhere where quick service is in dispensable and required. Another object of my improvements is to in clude in the elements coacting in the mech 10 anism of my said contrivance, means for releas ably resiliently locking the device when in on cans, thus relieving the operative from necessity of keeping manual control of means when holding, transporting or using 15 device at the times mentioned. use the this the Another object of my invention is to fashion the device for manual use and whereby a can to be treated may be openly encompassed from the front thereof by readily releasable means quickly operable. whose upper edge or edges may be indented at 3 to receive the lower head ?ange of the can to prevent dislodgement while being operated upon. The projection or projections 2 terminate in a ?at ring 4 to receive the lower end part of an erect tubular or cupped standard 8, and a set screw 5 may be used to adjustably secure said elements together to permit the ring base I to be raised or lowered as desired, but this ring base may be permanently ?xed on the standard. A 10 handle l2 may be ?xed on at the rear to said standard. A coiled compression spring ‘1’ is po sitioned in the lower part and hollow of the standard to extend upwardly therein a suitable distance, and a cylindrical stem 8 is in part mov ably inclosed in the standard, vresting upon the upper end of said spring, and to project above the upper end of the standard a suitable dis tance, and this stem carries a forwardly di rected planar horizontal arm 11% rigidly, the forward end of the arm having a vertical hol low body l9 rigid thereon, having preferably a Another object of my improvements is to in clude in the device means for permitting its use - delivery spout 215 on and communicating with in inclo-sing and treating cans of differing di mensions conveniently, and obviating the neces 25 sity for the employment of a plurality of the devices for separate use thereon. Another object of my improvements is to in clude in the mechanism means for adjusting a vent-tube and perforater therein to thus equip 30 the invention suitably for use upon cans of dif ferent diameters, while releasably engaging them therewith. These and other improvements to be described, are treated of in the speci?cation, claims and 35 drawing hereof, but it is to be understood that various changes may be effected in the device, in its structures and connections, without de parting from this invention or the appended claims. Fig. l is a side elevation of my improved can 40 opener and dispenser, showing it extended in full lines, and with certain moving elements thereof displayed also in broken lines to show it in op erating position and relation to- a can to be 4.5 opened used in dispensing or evacuating its oil or other liquid contents, parts being sectioned or broken away. Fig. 2 is a detail view of the resiliently controlled canting brake device, seen from the rear of the invention as in locked con 50 dition with the movable stem support of the combination can perforator and delivery spout. The numeral I denotes a circular horizontal ring base upon which a can to be treated may be removably mounted, the ring having a radial 55 projection or parallel pair of such projections 2 its upper end. The lower depending portion of the body l9 has a ?xed circular ?ange 20 therearound, and a rubber washer, downwardly concaved, at 2| is seated removably on the de pending part of said body and stopped by the ring 20. A little below this washer the termina tion of body 19 is obliquely shaped and pointed at 23, and the body l9 has a notch forwardly at 22 just above said beveled edge or cutting point 23. The arm l8 has a medial bearing hole 32 in which is seated movably a pin 25, headed at the top, threaded at its lower end to seat there on a nut 28, and a short arm 2i is apertured to be loosely bracketed on said pin intermediate the bar It and said nut. A hollow depending punch 30 has its upper end ?xed in said arm ‘2i, and has a beveled piercing termination 3!. The numerals 29 and 33 denote respectively a pair of vertical holes in the arm l8 disposed at equal distances oppositely from the pin 25, and to receive alternately the slightly upwardly directed end of the hollow punch 30, as shown in dotted lines, whereby this punch may be employed‘ to punch air-vent holes in can tops of two different diameters, a pair of such cans being depicted in dotted lines in Fig. l. The arm 21 is lowered a sufficient distance when the pin 25 is pressed down, so that the arm may be rocked to either hole 29 or 33, and when the same is registered with either, the pin may be released, to allow the upper part of the punch 2 2,125,002 30 to enter and engage the wall of either hole 29 or 33. ' Referring particularly to said Fig. 2, the nu meral l3 denotes an upwardly directed eyed member or ring secured at its lower end to one side of the standard 8 near it stop and to slid ably and rockably seat an otherwise free end of a laterally projecting arm including an annular part l4 which has an outwardly bent ?nger piece l5. The numeral l6 denotes an upwardly obliquely directed bent ?nger ?xed on the oppo site outer wall of the standard 8, and carries on its upper end a short coiled compression spring I‘! whose upper end engages beneath the 15 annular part M tending to rock the latter up to cant upon the stem 8 above the standard, to lock therewith frictionally, but releasably. Within the hollow of the standard 6 the stem 8 has a longitudinal slot 9 therethrough, loosely 20 traversed by a cross pin [0, with bolt-head II and nut not shown on the opposite end, said pin also traversing the wall of the standard ?xedly, and thus to limit the up and down play of the stem in the standard. Operation-A closed can, ?lled with oil or other liquid, as shown in dotted lines in di ameters of di?erent length, may be seated on the ring base I. The air vent punch 30 may be if necessary adjusted to locate it in either arm hole 30' 29 or 33, according to the special diameter of the can to be treated, as shown in full and dotted 25 lines respectively. Then the operator manually presses downwardly upon the arm 18, thus caus ing the pointed cutting terminations 2-3 and 3| of 35 the punches l9 and 30 to puncture and pass be low the top wall of the can a sufficient distance to locate these parts within the can, including the notch 22 in the punch IS. The arm H5 in descending compresses the spring ‘I in the hollow 40 of the standard 6. The operator meanwhile also rigidly connected air-vent and spouted hollow punches, supporting means upon which they are resiliently mounted for to and fro movements relative to a can to be punctured and tapped by both, and the puncturing termination of the spouted punch having a lateral drainage aperture a to open into the can ?ush with the lower face of its top wall for complete drainage of the in verted can when punctured thereby. 2. In a device of the character described, 10 rigidly connected air-vent and spouted hollow punches, supporting means upon which they are mounted for punching a wall of a can to be dis charged of liquid contents, the puncturing ter mination of the spouted punch having a drain age aperture opening into the can ?ush with the inner lower face of its top wall when the can is inverted and an elastic washer for sealing the joint of the said punch and can. 3. In a device of the character described, a rigid supporting member, a terminal spouted punch thereon having a cutter end for penetrat ing a wall of a can to be discharged of its liquid contents, and an air-vent hollow punch on said member for simultaneously penetrating the can 25 together with the spouted punch, said air-vent punch being loosely rockably, mounted on said member endwise, and the member having spaced seats therealong; with which the latter punch may be releasably engaged with either to permit said 30 punches to be spaced from each other variably to operate upon cans of diifering diameters. 4. In a device of the character described, a rigid supporting member mounted for to and fro movements relative to a closed receptacle to be 35 tapped, a terminal spouted punch on said mem ber having a cutter .end for penetrating a can end, an air vent hollow punch mounted loosely on said member swingingly, the punch being adapted for releasable engagements with differ ent parts of the member to adjust its position of depresses the'bent arm l4 and [5 by his thumb, holding the ring I 4 released loosely from the spacing apart from the spouted punch releasably, stem 8.

A device of the character described, com pressed, to recoil and push upwardly rockingly prising in combination, connected spout carrying the ring part M to frictionally cant upon and and air-vent hollow punches, the spout carrying with the wall of the stem 8 to hold the stem 8 and the punches l9 and 30 at rest in the posi 50 tions shown in dotted lines in Fig. 1. The op erator then’ may tilt the can by using the handle I2 to evacuate the whole or a portion of its liquid contents from the can. When the can is emptied, the bent arm or lever l4 and I5 may be 55 pushed downwardly to release the stem 8, the compressed spring ‘I then recoiling upwardly to return the arm l8 and its punches to initial po sitions. The downwardly concaved washer 2i serves to 60 seal the can around the punch, and the notch 22 serves when the can is tilted su?iciently to evacuate the contents, to drain out any portion of liquid which may coat the interior wall of the can. The device in its forwardly open state may 65 thus conveniently receive a can or permit its re moval forwardly, without interference with ad jacent objects. It will be understood that the slot 9 in the stem 8 is long enough to permit the punches to be used with cans of di?’erent heights 70 in the puncturing of their top walls. I claim: 1. In a device of the character described, punch having a cutting termination and a wall aperture adjacent thereto for drainage of a can nearly discharged of its contents, the air-vent 50 punch being horizontally rockably and adjustably associated with the spout carrying punch to space it in any of different distances therefrom simultaneously in use and for air venting the can punctured by and discharging through the spout carrying punch, and resilient supporting means for said punches, with means manually operable to brake and hold releasably said supporting means while the can is being discharged of its contents punches. or while being engaged with the 6. A device of the character described, com prising in combination, connected discharge and spout carrying and air-vent hollow punches, the air-vent punch being supported and positionally 65 adjustable to and from the: spout-carrying punch, means for releasably holding the punches re-, siliently braked when in communication with a closed liquid containing can punctured thereby, and means for adjustably limiting the scope of movements of said punches. .
