FIG. 4.

INVENTORS ARLEEN F AC AND HUBERT VAN BREE ATTORNEYS Patented F eb. 8, 1938 UNITED STATES PATENT OFFICE This invention appertains to self-contained electrically driven clippers, and more particularly to clippers of the type having removable.

unitary cutting assemblies.

It is now customary to provide electrically driven hair clippers and clippers for giving dry shaves. Some clippers have cutting assemblies (that is, assemblies of fixed and movable blades) 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 be had, and whereby different types of cutting assemblies, such as for hair cutting or dry shaves, can be quickly and expeditiously connected with or detached from said body portion.

Another salient object of our invention is to provide spaced posts rigidly mounted on the cutting assembly for snug insertion in sockets formed in the body, so that all lateral shifting of the assembly relative to the body will be prevented, and whereby no difiiculty will be encountered by the operator in associating the assembly with the body.

A further important object of our invention is the provision of novel means associated with the body for releasably engaging said posts, whereby accidental displacement of the posts and the as sembly from the body will be prevented.

A still further object of our invention is the provision of a simple and effective means including a thumb-operated lever for releasing the posts from their holding means and for displac- "ing the cutting assembly from the body.

structed in accordance with our invention, parts thereof being shown broken away and in section to illustrate structural details. I

Figure 2 is an enlarged, fragmentary transverse section through the clipper taken substanx tially on the line 2-2 of Figure 1, looking in the direction of the arrows, illustrating the means for detachably engaging the posts. Figure 3 is a fragmentary sectional view taken substantially on the line 3-3 of Figure 1, looking in the direction of the arrows, illustrating the pivot for the operating lever. v

Figure 4 is a detail perspective view of the operating lever.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout-the several views, the letter C generally indicates the clipper, which comprises a body portion I. This body portion I can be made from any preferred materials and in any desired shape, and forms the housing for the electric drive motor (not shown).

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 armature shaft 8 of the motor for rapidly oscillating the actuating lever 8. This lever 0 extends forwardly 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 p rp se of which will be hereinafter more fully set forth.

The cutting assembly It comprises a fixed blade I! and a movable-blade l4. 'Ihe movable blade I4 is resiliently urged toward the stationary blade i2, and has formed therein a socket for receiving the forwardly extended end of the oscillating lever '8. The rear edge of the stationary cutting blade I! has formed thereon a rearwardly directed plate It, which is adapted to lie close up against a portion of the inclined face I of the head I.

This inclined surface 1 has formed therein a longitudinally extending groove II, the purpose of which will be hereinafter more fully set forth. This plate II has rigidly secured thereon a pair 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 firmly 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 facilitating the insertion of the posts in sockets and for another purpose, which will also be later set forth.

Directly inward of the tapered ends, the posts have formed therein annular grooves 2i, which constitute keeper sockets for latch pins 22. The latch pins 22 are normally urged into the sockets II by means of springs 23. The springs 23 are confined in place by removable threaded plugs ,carriedbythesides of theheadi. The plugs 24 form a convenient means for permitting the assembly of the pins 22 and springs in the head.

Arranged within the groove I6 is a releasing lever 25. This releasing lever 25 has formed therein 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 fit 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 engage the plate of the cutting assembly, and thus move the posts outwardly of the sockets, releasing the same from the spring-pressed pins 22. The rear end of the lever can be provided with an inwardly directed guide tongue 30 for movement into a guide socket 3! formed inthe head i.

In use of our improved clipper, when it is desired to associate a cutting assembly with the body portion of the clipper, it is merely necessary to insertthe posts l1 and I8 into the sockets l0 and II until the plate firmly engages the inclined face I. The tapered portions of the studs or posts l1 and I8 permit the ready springing back of the spring-pressed pins 22, and, obviously, when the posts are in their fully inserted position the spring-pressed pins will engage in the grooves 2| and hold the posts and consequently the cutting assembly against accidental displacement.

As stated, by merely pressing on the outer end of the lever 25, the posts can be forced outwardly of the sockets and past the spring-pressed pins.

By our construction, different types of hair cutting 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 firm connection to be had between the body portion of the clipper and 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 both for hair cutting and shaving.

Changes in details may be made without departing from the spirit or the scope of our invention, but what we claim as new is:

1. In a clipper, a body portion provided with a pair of spaced sockets, unitary cutting assembly for detachable association with the body, rigid posts carried by the cutting assembly for movement into and out of the sockets, releasable means carried by the body for engaging the posts to hold the posts against accidental displacement, and manually actuated means having a portion disposed between the body and the cutter 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 forwardly 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 inwardly from said inclined surface for receiving the posts, releasable means engaging said posts for holding the same against accidental displacement in the sockets, and a manually operated lever rockably mounted on said head having its inner end extending between the cutting assembly and said face adjacent to the posts.

3. In a clipper, a body portion having a forwardly extending head provided with an inclined lower surface and sockets extending inwardly from said surface, a unitary cutting assembly including a stationary blade and a movable blade, a rearwardly extending plate on the stationary blade adapted to fit against said inclined face, rigid posts carried by said plate for insertion in said sockets, spring-pressed pins carried 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 moving the cutting assembly and the posts away from the head, said means including a pivotally mounted lever having its forwardend extendin between the plate and said inclined surface.

4.-In a clipper, a body portion having a forwardly extending head provided with an inclined lower surface,,a pair of sockets extending inwardly from said surface, and a groove located between the sockets, a cutting assembly including a stationary blade and a movable blade, a rearwardly directed plate formed on the stationary 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 annular grooves, spring-pressed pins carried by the head for engagement in said grooves when the posts are fully inserted in said sockets, an operating lever having an opening arranged between the ends thereof and inwardly directed 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 being 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 finger manipulating surface thereon.
