HAIR-CLIPPER.

Specification of Letters Patent. P t t A 6 1 Application filed January 14, 1920. Serial No. 351,370.

To all whom it may concern: Be it known that we, SIDNEY P. Jonns and DA ID P. WALLACE, citizens of' the United States, residing at Waco, inthecounty of McLennan and State of Texas, have invented certain new and useful Improvements in Hair-Clippers, of which the following is a specification.

This invention relates to new and useful improvements in hair clippers.

The invention has particularly to do with double acting clippers and the result sought is to perform a higher percentage of the hair cutting operation than is possible with a single blade device. v

The clippers now in common useemploy a fixed cutting bar and a single cutting blade reciprocating across the bar, these parts being disposed, as a rule, transversely of the device. With such an arrangement it is only possible to cut the air in an upward direction. Itflis not possible tomove the clippers downward over the hair, nor is it practicable to attempt to move them laterally or circumferentially ofjthe head. A part of the Work is done with the usual clippers, but the greater portion is executed with shears. We propose to do substantially all of the work with clippers and to eliminate the shears, except for fine trimming in some instances.

In carrying out the invention we employ two cutting means disposed transversely and longitudinally ofthe clippers, whereby hair cutting maybe accomplished by moving the device longitudinally or transversely. Such an arrangement permits hair cutting in any direction. In order that the ends of long hair may be clipped off, a comb is associated with one of the cutting means so as to support the hairs while they arebeing clipped.

In reducing the invention to practice we have found it advantageous to dispose one cutting means transversely across the for- Ward end of the device at an incline and with a fiat surface preceding the cutting means; while the other cutting means is dis posed longitudinally at one side of a longitudinal boss or enlargement which acts as a fulcrum in rocking the device to vary the length at which the hairis out; A comb is associated with the side or longitudinal cutting means and may be removable- Other features will be hereinafter brought out.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the I invention is shown, and wherein:

. Fig. 7 is an underside view showing the comb, and

Fig. 8 is a detail of the driving gears.

In the drawings the numeral 10 designates a housing or casing on whicha cover or cap 11 1s secured; these parts constituting a head. The casmg has its forward end inclined up- Fig. 318' a cross-section on the line 3-3 of ward at 12 transversely of the head to form a bearing surface co-acti'ng with an under cutter 13 fastened'in the forward end of the casing. A reciprocating cutter 14 is mount ed on -the forward end of the cutter and registerswith the teeth thereof. 'Upright guide pins 15 extend through slots 16 in the blade 14, said slots having ample length to permlt'a free reciprocation of the blade.

The bottom'of the casing is rounded trans- ]versely thereof and provides a longitudinal .boss 1? which acts as a fulcrum inrocking the casing laterally. From one side of the boss the bottom is inclined upward to the side edge of the casingand forms'a fiat surface. At this point thecasing'is enlarged to provide a support 18 so that a second cutter 19 may be fastened along one side of the casing'with its teeth extendinglaterally from said casing. A reciprocating cutter 2( is, providedwith slots 21 receiving guide plus 22 projecting? upward from the For reciprocating the cutters 14 and 20 we employ a central shaft 23 mounted longitudinally of the casing in transverse bear ing members 24. At its forward end the shaft has fixed thereto, an eccentric engaging in an elongated housing 26 (Flg. 6) integral with an arm 27 extendlng rear- 7 wardly from the blade 14. This arm is bent between themembers 24 and is provided at an angle to the blade so as to present the housing at right angles to the shaft and parallel to the eccentric.

It will be seen that when the shaft is revolved the eccentric will rotate in the housing and reciprocate the blade 14.

A cam wheel 28 is fastened on the shaft 1' ferential motion to the cutters and the motive means is thus made very simple.

.The cap ll'has-a'straight .transverseedge 32 across its'front. end engaging in a groove 33 extending longitudinally of the blade 14. Along one side the'cap has a down turned edge 34 engaging in a groove 35 which extendslongitudinally of the blade 20. A curved armor support 36 'extendingup from the casing within the'cap,-carries an upright post 37 which projects up through a boss 38 at the center of the cap. The post is screwthreaded to receive a wing nut 39' which bears on spring bowed washer 4O resting on the boss. It will be seen that by screwing the nut downward the washeris compressed and exertsa spring tension on the cap. The edge 32 and 34 of the cap engaging in the grooves of the blades hold said blades in close contact with the blades lying thereunder; a variable tension may thus be had onthe blades by simply adjusting the thumb nut. The edges of the cap engaging in the grooves of the reciprocating blades not only serve as guides, but tendto prevent the clipped hairs from working under the cap and" clogging the motive parts.

-Ears 41depending from the front end of the cap: overhang each side of the casing and give the head a smooth finish. At the rear end the casing is secured to a hollow bracket 42. A spur gear 43 is mounted on the end of the shaft 23 within said bracket and is driven by a spur pinion 44 fastened on the end of a, drive shaft 45. The drive shaft is suitably mounted in a tubular handle 46 having'an enlargedflange 47 screw-threaded to receive a screw-threaded collar-48 projecting from the bracket. WVhn the handle is removed from the bracket the drive shaft and pinion'44 are removed with it. It will be seen, particularly by observing Figs. 1, 2 and 3, that the handle is offset laterally with relation to the side blades and vertically 17 when the side blades 19 and 20 are'being used. 7

The drive shaft 45 is suitably arranged to be connected with a flexible driving shaft .49 which may be propelled by any suitable means. The drive shaft 45 drives the pinion I 44 which drives the gear 43 thereby revolving the shaft 23. The shaft 23 as before explained revolves the eccentric 25 and the cam wheel 28, by which the blades 14 and 20 are reciprocatedi In using the clippers'the front cutter is used forthe usual vertical work such as the back and sides of the head and temples. It

is only practical to use the'front cutters for cutting in an upward direction. In order to cut the hair on top of the head and also to cut in a lateral direction the side cutters are used. It is almost impossible to clip the ends of long hairs without. some kind of a support; therefore we have provided an attachable comb 5O fitting in a clip 51 on the under surface of the support 18. The comb is shaped so that its teeth will register with the teeth of the blade 19 and extend some distance from the same This comb will support the hairs while they are being cut. Such an arrangement permits the operator to clip off the long'hairs on top of the head and work downwardly and laterally. The boss 17 permits the device to be rocked topull the hairs through the'comb and graduate the lengths at which they are cut. It is obvious that a comb could be used in connection with the front cutter.
