HAIR CLIPPER. APPLICATION FILED MN. 14. 1920 1,356,866, Patented Oct. 26,1920.

* N D T TE A NT oF lcEQ SIDNEY I. JONES AND DAVID P. WALLACE, OF WACO. TEXAS;

To all whom itmay concern:

' Be it known that we, SIDNEY P. JONES and DAVID P. VVALLACE, citizens ofthe fication and by reference to the accompany- United States, residing at Waco, in the 7 county 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 purpose ofthe invention is to provide a power driven device Which will be positive in action, comprise a few number of parts, and one which will be efficient, simple and easy of operation, as well as substantial and superior in arrangement and convenience.

In carrying out the invention a shoe is provided with a stationary cutter on which a reciprocating cutter is mounted. A shank carries the shoe and cap which bears upon and covers the greater portion of the reciprocating cutter. By placing the cap under tension the cutters are regulated.

The shank contains a novel and simple means. for positlvely reciprocating the movable cutter. The shank is supported from a handleby a bracket, whereby the shank is .off-set from the handle so that the device may be conveniently held by the operator. The shoe is given a particular structure which lends to a more satisfactory manipulation of the device. i

The invention will be more readily understood from areading'of the following speciing drawings, in which an example ofthe f invention is. shown, and wherein:

Figure 1 is a plan view of a device constructed in accordance with this invention, Fig. 2 is a side elevation of the same,

Fig. 3 is an underside view of the shoe and shank portions,

Fig. 4 is a longitudinal sectional view of the parts shown in Fig. 3, but on an enlarged scale,

Specification of Letters Patent. Pat t d t, 2 192 Application filed January 14, 1920.1 Serial no. 351,369. 2

In the drawings thenumeral1O designates a shoe which has an upwardly inclined under surface 11, the latter beingslid over the skin of the person. This shoe has its surface 11 terminating at its lower end in a rounded heel 12 extending transversely and acting as a fulcrum on which the shoe may be rocked and obviating a sharp edge at this point. The upper surface of the shoe is inclined downwardly and supports a transverse cutting blade 13. Studs 14 having beveled collars 15 are screw-threaded into the shoe so that the collars thereon are countersunk in the blade 13 (Fig. 5) and the latter fastened in position. The teeth of theblade project beyond the shoe and the blade has a longitudinal oil channel 16 in its upper surface.

A reciprocating blade 17 is provided'with slots 18 receiving the studs 14c,said blade riding on the blade 13. The shoe is made integral with a tubular shank 19 and the blades have their rear edges at about the center of said shank. A cap 20 has a depending lip 21 along its" front edge engagsurface extending to the top of the shank. 'A lug 241 projecting from the rear of'the cap is engaged 'in the top of the shank and prevents upward displacement of the cap. A sprin'g arm 25 fastened to the cap extends rearwardly and overhangs the center ofthe shank at which point it carries a tension screw 26 having a point engaging in the shank, (Fig. 1). By adjusting the screw, the lug 24 becomes a fulcrumand the lip 21 is forced down into the groove 22 whereby the blade 17. is placed under tension. The tension may be regulated by adjusting the screw. 7 a

The blade17- has a pair of integral fingers 27 projecting from its central rear portion.

The blade 17 is at an incline and the fingers engage in inclined sockets 28 oneach side of a' keeper 29. This keeper has a vertical recess 30 (Fig. 8) in its rear side to receive and confine an eccentric 31 fixed on the front end of a counter shaft 32. The keeper bears against the rear faces of the shoe and cap and is confined between the same and a keeper 29'laterally to each side of the shaft,

thereby reciprocating the blade 17 a The shank is screwed into the lower front side of a hollow bracket 35 in which a gear 36 is mounted on the rear end of the shaft 32. A tubular handle 87 has an annular flange 38 at its forward end internally screw-threaded to receive a collar 10 on the upper rear side of the bracket. 'A drive shaft 39 is mounted in the handle and carries a pinion ll on its forward end which meshes with the gear 36.

In using the device the drive shaft 39 is suitably connected with a flexible shaft (not shown) in the handle and the said drive shaft thus driven by any suitable means, as an electric motor. The blade 17 is thus reciprocated very rapidly by means of the shaft 33 eccentric 31 and keeper 29. 'The operator grasps the handle 37 and theshank l9 and shoe 10 being off-set or depending from the handle, give room for the knuckles of the operators hand under the handle. The shoe through its inclined surface 11 will ride over the skin of the person having his hair clipped in an easy and convenient manner so that the cutters perform their func' tion very efficiently. The rounded heel 12 permits the shoe to be easily rocked, whereby the cutters may be swung outward in finishing the upward stroke. The arm 25. is pivoted. on the cap and may be swung to one side so that the cap may be swung upward and pulled outward to withdraw the lug 24 and remove the cap. The blade 17 may be lifted from the studs, whereby the keeper will be lifted, after which said blade may be pulled outward and removed. By unscrewing the studs lt the blade 13 may be removed.
