UNITED STATES GEORGE SEKULICH, OF NEW YORK, N, Y.

HAIR CLIPPER.

Application filed August 22, 1927.

This invention relates to hair clippers, and the primary object of the invention is to provide simple and etlicient means whereby the handles can be set at any desired angle with respect to the head of the clipper without the necessity of taking the clipper apart or varying its construction and operation.

A further object is to provide a hair clipper embodying the handle adjustment referred to above, and possessing simple and durable construction as well as being ellicient and reliable in operation. Other objects will become apparent as the nature of the invention is better understood, and the same consists inthe novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters indicate corresponding parts throughout the several views,

Figure 1 is a top plan view of a hair clipper constructed in accordance with the present invention;

fFigure 2 is a side elevational view there Figure 3 is a fragmentary bottom plan view of the handle which is adjustably associated with the head member of the clipper;

Figure 4 is an enlarged top plan view of the clipper with thehandles removed;

Figure 5 is a horizontal section on line 55 of Figure 2;

Figure 6 is a vertical section on line 6-6 of Figure 1;

Figure 7 is a transverse section on line 77 of Figure 1; and

Figure 8 is a horizontal section online 8-8 of Figure 6.

Referring more in detail to the drawings, the present hair clipper comprises an inverted U-shaped head member 5 having a comb plate 6 rigidly secured to the lower ends of the legs thereof by means of stud screws 7 which pass through the comb plate inwardly of the teeth 8 of the latter and are removably threaded in sockets in the lower ends of the legs of the head member 5 where by the comb plate is removably attached to the latter. Slidably disposed upon the comb plate 6 is the cutter plate 9 having a relatively large rectangular central opening 10 into which the legs of the head member 5 project. As shown clearly in Figure a,

Serial No. 214,737.

the legs of the head member 5 engage opposite walls of the opening 10 and are of lesser width than the latter so as to permit the cutter plate to slide back and forth upon the comb plate in a generally well known manner. The cutter plate 9 is yieldingly held in one limit of its movement by means of a helical compression spring 11 which is arranged within the opening 10 of said cutter plate and bears at one end against the latter at one end of the opening 10 and at its other end against a connecting bar 12 provided between the lower ends of the legs of the head member 5.

Journaled in the central horizontal por tion of the head member 5 is a vertical shaft or spindle 13 having a ratchet wheel 14 fixed upon the lower end thereof between the cutter plate 9 and the horizontal intermediate portion of the head member 5, and pivotally mounted upon one end of the comb plate 9 is a pawl 15 arranged to engage the teeth of the ratchet wheel 14: so that when the latter is turned in a clockwise direction as seen in Figure 5, the cutter plate 9 will be forced or slid relative to the comb plate against the action of spring 11, thereby effecting a cutting operation by cooperation of the teeth 16 of the cutter plate with the teeth 8 of the comb plate. As shown, the pawl 15 is yieldinglyheld in engagement with the teeth of the ratchet wheel 14: by means of a suitable wire spring 17 having an end as tened in the adjacent leg of the head member 5. The cutterplate 9 is pressed into frictional engagement with the upper surface of the comb plate 6 by means of a presser plate 18 which is arranged upon the cutter plate9 and between the legs of the head member 5 beneath the ratchet wheel 14, so as to substantially close the opening 10 of the cutter plate and retain the spring 11 in place. As shown, the resilient presser plate 18 is preferably of transversely curved form and is anchored at one end upon a screw 19 which has a reduced lower end 20 pivotally engaged in an opening 21 in one end of the cutter plate 9, the pawl 15 being threaded onto the screw 19 above the adjacent end of the pressure plate 18 as shown clearly in Figure 7. As the plate 18 is di rectly beneath the ratchet wheel 14, the screw 19 will be held with its end 20 engaged in the opening 21, and by vertically adjusting the adjacent end of plate 18 and pawl 15 relative to the screw 19, the plate 18 may be flexed to exert the desired pressure at its other free end upon the cutter plate. Such adjustl'nent of the plate 18 and pawl 15 may be effected by holding these parts against turning and rotating the screw 19, in an obvious manner.

Rotatably mounted upon the shaft or spindle 13 directly above the horizontal intermediate portion of the head member 5 is the hub memberil formed upon one end of a stationary handle 22. Provided in the upper surface of the horizontal intermediate portion of the head member 5 is a circular series of radial grooves :23. and carried by the handle 22 is a pivoted spring pressed catch 24 having one end vieldingly project ed to engage in a groove 23 to prevent turning of the handle 22 of the clipper relative tothe head'thereot. The catch 24 preferably has a linger piece 25 exposed the upper side ofthe handle 22 and adapted to be pressed for swinging the catch and releasing its lower end from the associated groove 23. Obviously, when the catch 2- isreleased. the handle .22 may be swung about the shaft 13 to any desired angular position relative to the head of the clipper, and upon releasing the catch 24, it will engage in the registered one of the grooves 23 for holding the handle in its adjusted position. An operating handle 26 has one end fastened upon the upper end of the shaft or spindle 13 so that when the handle 26 is pressed toward the handle the ratchet wheel 14: will be turned in the proper direction for sliding the cutter plate 9 against the action of spring 11 through the mcdiun'i of pawl 15. the cutter plate Slreturning to its normal position underthe action of spring 11 as soon as the handle 26 is released. Obviously,b v swinging the handle 26 in a counter-clockwise direction or away from the handle 22, said handle 26 maybe adjusted at any desired angular position :relative to the head of the clipper, the ratchet wheel 14 freely ratcheting past the pawl 15 at such time. When the handle 26 has been properly adjusted, the corresponding adjustment of the handle 22 may be subsequently efi'ected to .o'btainlthe desired (relation between the handles as will beapparent. As shown, the shaft 13 has an externally threaded upper end onto which the adjacent end of the handle "26 is threaded. and provided in this uppervendof shaft 13 is a 'bore into which is threaded .a Wedge plug 27 by means of which the threaded upper end of the shaft 13 is expanded to firmly lock the handle 26 to :the shaft 13 and likewise secure the nut 28, which is threaded upon the shaft 13 above the handle 26, from turning. "The expansion :of the upper end .ofshaft 13 is facilitatedby longitudinally slottingthe "bored portion of the same as at 29. In this way, the handle 26" is ettcctivdly fastened on the upper 'end of the shaft or spindle 13 so as to cause turning of the latter when the handle 26 is actuated, and at the same time the parts may be read ily disassemltiled by removing the plug 26 to free the nut 28 and handle 29 for being threaded off of the shaft 13, the upper end of the latter being reduced so that said shalt may be moved dowmvardly through the opening in the head member 5 after the comb plate 6 is detached therefrom by relnoval of the stud screws 7. Naturally, this provides for convenient mamitacture and assembly.

As shown, the cutter head may be reversible by providing opposite edges of the comb and cover plates with teeth, the cooperating tecth at one side of the head being preterabl i finer than those atthe other side and adapted for selective use in accordance with requirements. As the handles are adjustable to any desired angular position completely about the axis defined by spindle 13, any desired angular adjustment of the handle relative to either pair of cooperating cutting edges of the head, may be had.

The operation having been dealt with as the description progressed, it is bclicrcd that the manner of use as well as the advantages of the invention will be readily appreciated bythose skilled in the art.

Minor changes may be made without departing fromthe spirit and scope of the invention as claimed.
