Application August 0, 193s, Serial No. mm 4 Claims." (01. 30-20:) This invention appertains to self-contained Figure 4 is a detail perspective view of the op electrically driven clippers, and more particu erating lever. ' larly to clippers of the type having removable. Referring to the drawing in detail, wherein unitary cutting assemblies. It is now customary to provide electrically driven hair clippers and clippers for giving dry shaves. Some clippers have cutting assemblies similar reference characters designate corre sponding parts throughout-the several views, the letter C vgenerally indicates the clipper, which comprises a body portion I. This body portion ' (that is, assemblies of ?xed and movable blades) ' I can be made from any preferred materials and which may be attached to or detached from the body portion of the clipper. One of the primary objects of our invention is to provide a novel means for connecting the cutting assembly with the body of the clipper, whereby a strong and sturdy construction will 15 be had, and whereby different types of cutting assemblies, such as for hair cutting or dry shaves, can be quickly and expeditiously con nected with or detached from said body portion. Another salient object of our invention is to provide spaced posts rigidly mounted on the cut ting assembly for snug insertion in sockets formed in the body, so that all lateral shifting of the assembly relative to the body will be pre vented, and whereby no di?iculty will be encoun 25 tered by the operator in associating the assem bly with the body. , - A further important object of our invention is the provision of novel means associated with the in any desired shape, and forms the housing for the electric drive motor (not shown). 10 The forward end of the body portion I carries a head I having an angularly extending lower face ‘I. Extending into the head 8 is the arma ture shaft 8 of the motor for rapidly oscillating the actuating lever 8. This lever 0 extends for wardly of the head I, for a purpose which will be later setforth. The lower inclined face ‘I of the head has formed therein a pair of spaced sockets ill and Ii, the purpose of which will be hereinafter more fully set forth. 20 The cutting assembly It comprises a ?xed blade I! and a movable-blade l4. 'Ihe movable blade I4 is resiliently urged toward the station ary blade i2, and has formed therein a socket for receiving the forwardly extended end of the NI5 oscillating lever '8. The rear edge of the station ary cutting blade I! has formed thereon a rear wardly directed plate It, which is adapted to lie body for releasably engaging said posts, whereby accidental displacement of the ‘posts and the as; close up against a [portion of the inclined face ‘I sembly from the body will be prevented. ‘ A still further object of our invention is the This inclined surface 1 has formed therein a - provision of a simple and effective means includ of the head I. _ 30 longitudinally extending vgroove II, the purpose of which will be hereinafter more fully set forth. ing a thumb-operated lever for releasing the - This plate II has rigidly secured thereon a pair posts from their holding means and for displac "ing the cutting assembly from the body. with these and other objects in view, the in vention consists in the novel construction, ar rangement, and formation of parts, as will be 40 hereinafter more speci?cally described, claimed and illustrated in the accompanying drawing, in which drawing: ‘ Figure 1 is a side elevation of a clipper con structed in accordance with our invention, parts 45 thereof being shown broken away and in section to illustrate structural details. I - of upstanding posts or studs ii and II, which are adapted to be snugly received within the sockets II and ii. v . vAs illustrated, screws I! extend through the plate l5 and into the studs or posts l1 and It for ?rmly connecting the posts or studs to the plate. These screws II and the posts can be utilized for holding the resilient plate 2| for the movable blade It in place. If preferred, the outer ends of the posts can be tapered for facili tating the insertion of the posts in sockets and for another purpose, which will also be later set forth. Figure 2 is an enlarged, fragmentary trans verse section through the clipper taken substanx Directly inward of the tapered ends, the posts tially on the line 2-2 of Figure 1, looking in the have formed therein annular grooves 2i, which 50 direction of the arrows, illustrating the means constitute keeper sockets for latch pins 22. The 50 for detachably engaging the posts. - latch pins 22 are normally urged into the sock ' Figure 3 is a fragmentary sectional view taken ets II by means of springs 23. The springs 23 substantially on the line 3-3 of Figure 1, looking are con?ned in place by removable threaded in the direction of the arrows, illustrating the plugs “,carriedbythesides of theheadi. The pivot for the operating lever. v , _ plugs 24 form a convenient means for permitting 2,101,750 2 the assembly of the pins 22 and springs in the head. Arranged within the groove I6 is a releasing le ver 25. This releasing lever 25 has formed there in intermediate its ends an opening 26 for the reception of a holding screw 21, which is threaded in a socket 28 formed in the head 6. The screw 21 has a loose ?t in the opening 26, whereby the lever will be free to rock on the said screw. The sides of the lever have formed thereon‘ inturned wings 29 adjacent to the opening 26, and these wings engage the head and form a fulcrum for the lever. The forward end of the lever extends under the plate I5 between the studs or posts Ill and II, and by pressing on the outer end of the lever, the lever will forcibly en gage the plate of the cutting assembly, and thus move the posts outwardly of the sockets, releas ing the same from the spring-pressed pins 22. 20 The rear end of the lever can be provided with an inwardly directed guide tongue 30 for movement into a guide socket 3! formed in‘the head ii. In use of our improved clipper, when it is de sired to associate a cutting assembly with the 25 body portion of the clipper, it is merely neces sary to insertthe posts l1 and I8 into the sock ets l0 and II until the plate ?rmly engages the inclined face ‘I. The tapered portions of the studs or posts l1 and I8 permit the ready spring ing back of the spring-pressed pins 22, and, ob viously, when the posts are in their fully inserted position the spring-pressed pins will engage in the grooves 2| and hold the posts and conse quently the cutting assembly against accidental displacement. As stated, by merely pressing on the outer end of the lever 25, the posts can be forced outward ly of the sockets and past the spring-pressed pins. . By our construction, different types of hair cut ting assemblies can be readily associated with the head, and the cutting assemblies can be easily and quickly cleaned. The studs form an ideal means for permitting a ?rm connection to be 45 had between the body portion of the clipper and 40 the cutting assembly. Obviously, a dry shaver cutting assembly can be associated with the body 5, and thus the clipper can be of a universal character and used 50 both for hair cutting and shaving. Changes in details may be made without de parting from the spirit or the scope of our inven tion, but what we claim as new is: 1. In a clipper, a body portion provided with a 65 pair of spaced sockets, unitary cutting assem bly for detachable association with the body, rigid posts carried by the cutting assembly for move ment into and out of the sockets, releasable means carried by the body for engaging the posts 80 to hold the posts against accidental displace ment, and manually actuated means having a portion disposed between the body and the cut ter assembly for forcibly moving the assembly and the posts away from thebody upon actuation of said means. 2. In a clipper, a body portion having a for wardly extending head provided with an inclined lower surface, a unitary cutting assembly, rigid posts carried by said cutting assembly, the head having sockets formed therein extending inward ly from said inclined surface for receiving the posts, releasable means engaging said posts for holding the same against accidental displace ment in the sockets, and a manually operated le ver rockably mounted on said head having its in 15 ner end extending between the cutting assembly and said face adjacent to the posts. 3. In a clipper, a body portion having a for wardly extending head provided with an in clined lower surface and sockets extending in 20 wardly from said surface, a unitary cutting as sembly including a stationary blade and a mov able blade, a rearwardly extending plate on the stationary blade adapted to ?t against said in clined face, rigid posts carried by said plate for insertion in said sockets, spring-pressed pins car ried by the head normally urged in the sockets, said :posts having keeper recesses for receiving the pins when the posts are fully inserted in said sockets. and manually actuated means for mov 30 ing the cutting assembly and the posts away from the head, said means including a pivotally mounted lever having its forward‘end extending between the plate and said inclined surface. 4.-In a clipper, a body portion having a for wardly extending head provided with an inclined lower surface,,a pair of sockets extending in wardly from said surface, and a groove located between the sockets, a cutting assembly includ ing a stationary blade and a movable blade, a 4 0 rearwardly directed plate formed on the station ary blade adapted to engage said inclined face and overlie a portion of said groove, a pair of rigid posts carried by the plate for reception in said sockets, said posts being provided with an nular grooves, spring-pressed pins carried by the head for engagement in said grooves when the posts are fully inserted in said sockets, an op erating lever having an opening arranged be tween the ends thereof and inwardly directed 50 fulcrum wings on each side of said opening, a pin loosely extending through said opening and into the head, the forward end of the lever be ing disposed in said groove between the plate and the inclined surface and intermediate said . posts, the rear end of the lever extending beyond the plate and having a ?nger manipulating sur face thereon.
