ERNEST ALWEN VE'ITEB, OF BROOKLYN, YOZRI'L HAIR CLIPPER.

Application filed January 15, 1924. Serial No. 885,412.

Z '0 (6% whom, it may concern Be it known that I, Ennns'r A, Vrxrrnn, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Hair Clipper, of which the following is a full, clear, and exact description.

This invention has. relation to hair clipping devices and has particular reference to hair clippers of the reciprocatory knife ()ne of the outstanding objects of the present invention is to provide a clipping device in which the operating handles are so associated therewith as to dispose the same in laterally projecting relation to the outters whereby the clippers may be used by a person in the operation of cutting or clipping his own hair.

As a further object the invention contemplates a hair cutting device in which the operating handles are detfachably and reversibly associated with the cutting elements or knives to permit of their reversal and use with either hand.

As a still further object the invention aims to provide a hair clipping device which is comparatively simple in its construction and mode of operation, which is inexpensive to manufacture and produce, and which is higgly eflicient in its purpose.

ith the above recited and other objects in view, theinvention resides in the novel construction set forth in the following specification, particularly pointed out in the ap pended claims and illustrated in the accompanying drawings, it being understood that the right is reserved to embodiments other than those actually illustrated herein to the full extent indicated by the general meaning of the terms in which the claims are expressed.

In the drawings 7 Figure 1 isxa perspective view of a hair clipper constructed in accordance with the invention.

Fig. 2 is a plan view of the operating handles removed from the cuttingelements.

Fig. 3 is a diagrammaticplan view illustrating the manner in which the operating handles may be reversed.

Referring to the drawings by

characters ofreference

10 and 11 designate respectively a pair of blades each having a plurality of cutting teeth 12 at one edge thereof. The

blade 11 which will be hereinafter termed the movable blade is superimposed on the blade 10 which will be hereinafter termed the stationary blade and is connected with said stationary blade for reciprocation whereby the cutting teeth coact to set up a shearing action for clipping or cutting the hair. As illustrated, the stationary blade 10 is provided with a central upstanding shaft or trunnion 13 which extends through a longitudinal slot in the movable blade 11 and which is threaded for a purpose to be hereafter disclosed. The upper face of the blade 11 is longitudinally grooved as at 14 to receive therein the downturned guide flange 15 at the forward edge of the retaining and guiding plate 16 which overlies the blade 11. The rear edge of the plate 16 is provided with depending feet 17 which are received in the notches at the rear edge of the stationary blade 10. The trunnion or threaded shaft 13 projects through a central opening in the plate 16 and receives thereon an adjusting nut 19 between which and the plate a bowed leaf spring 20 is interposed for exerting a pressure on the plate 16 whereby its flange 15 in turn serves to impinge the blade 11 against the blade 10.

By turning the nut 19 in opposite directions the pressure may be increased or decreased to obtain the best results from the clipper. The nut 19 is provided with a reduced upwardly projecting annular boss 21 and the plate 16 is provided with apair of upwardly projecting

eccentric trunnions

22 and 23 adjacent spaced from the boss 21. The movable blade 11 is further provided with a rear wardly projecting car 24 having a bearing aperture 25 extending vertically therethrough. A pair of manipulating

handles

26 and 27 are pivotally connected at one end by a pivot sleeve 28 and are formed at their opposite free ends with finger receiving loops 29. The handle 27 which will be hereinafter termed the stationary handle has secured thereto adjacent its free end a leaf spring 80 which spring bears at its free-end against the movable member 26 at a point adjacent the pivoted end thereof whereby the free ends of the handles are normally swung apart. A stop lug 81 is provided on the stationary handle member for limiting the relative separation or opening movement of the handle members.

The internal diameter of the pivot sleeve its rear edge and equidistantly 28 is of a size to snugly fit over the boss 21 and the stationary handle member is further provided with an aperture 32 which is appropriately spaced from the plvot sleeve 28 to engage over either of the

eccentric trunnions

22 or 23 whereby the stationary handle member is coupled to the stationary blade against relative movement with respect thereto. The movable handle member 26 is provided with a lateral extension 33 at its pivoted end, which lateral QX'tGllSlOll 13 formed with a head 34 having oppositely projecting

vertical lugs

35 and 36 which are adapted to respectively engage with the bearing aperture in the ear 2 1 when the handle members are reversibly associated with the clipper blades, Under this con struction it is obvious that when the handle members are operatively associated with the clipper blades they project from the sides thereof so that the cutting teeth protrude at a right angle to the length of the handle members, thus facilitating the use of the device in the operation of a person cutting his own hair. In order to provide means for retaining the handle members in associated relation with the clipping blades, a retaining knurled nut 37 is threaded upon the free end of the threaded shaft or trunnion 13.

In use and operation, the handle members are associated with the blades by engaging the pivot sleeve 28 over the boss 21 and simultaneously engaging the aperture 32 in the stationary handle member 27 over the eccentric trunnion 23 with the depend ing vertical lug 36 engaging in the bearing aperture 25 of the ear 2t. The nut 37 is then threaded in place. The operator inserting the finger and thumb of the right hand in the loops 29 may then conveniently operate the device to clip upwardly at the back of the head. The relative opening and closing movement of the handle members will effect through the engagement of the lug 36 and the'bearing aperture 25 of the ear 2s relative reciprocation of the blade 11 and its teeth 12 with respect to the blade 10 and its teeth 12 whereby the shearing and cutting action is effected. When it is desired to clip upwardly with the, left hand, the retaining nut 37 is removed and the handle members arranged in reverse relation by engaging the aperture, 32 over theeccentric trunnion 22 with the lug and the bearing aperture 25 of the ear 24, it, of course, being understood that the pivot sleeve is also engaged over the boss 21 and the nut 37 replaced.

From the foregoing it will thus be seen, that a clipping device has been provided in which the operating handle members are capable of detachable and reversible association with the blades and protruding from the sides thereof in order to afford means which permits of the use of clippers in the operation of cutting ones own hair,

I claim:
