HAIR-CLIPPER.

SPECIFICATION forming part of Letters Patent No. 620,617, dated March 7, 1899.

Application filed October 80, 1897.

To all whom it may concern:

Be it known that 1, ANDREW M. SIMS, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of 0010- rado, have invented certain new and useful Improvements in Hair-Clippers, of which the following is a specification.

This invention relates to hair-clipping machines of the manually-operated type, and the chief object in view is to secure a number of reciprocating movements of the movable comb-cutter upon bringing the handles together and releasing them by the intervention of mechanism which will not add materially to the weight of the machine or to the size thereof, and which mechanism will be reliable and effective for the intended purpose and readily accessible for cleaning, sharpening of the cutters, and for making repairs.

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvementis susceptible of various changes in the form, proportion, and the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which- Figure 1 is a top plan view of a hair-clipping machine constructed in accordance with this invention. Fig. 2 is a central longitudinal section thereof on line y 3 of Fig. 1. Fig. 3 is a transverse section on the line so a: of Fig. 1. Fig. 4 is a detail view of the movable or reciprocating cutter or comb. Fig. 5 is a detail view of the vibrating arm.

Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings by the same'reference characters.

The machine comprises a casing composed of upper and lower parts 1 and 2, which are secured together by means of a bolt or like fastening 3. The lower part 2 is formed with or has applied thereto'a handle 4, which is relatively fixed or stationary, and a corresponding handle 5 is pivoted to the upper part 1 of the casing. The fixed cutter or comb 6 Serial No. 656,945. (No model.)

and operates over the fixed cutter 6, ballbearing 8 beinginterposed'between the cutter 7 and part 1 of the casing and operating in grooves or races 9 formed in the opposite sides of the said movable cutter, thereby reducing the friction to the smallest amount possible. The handles 4 and 5 are held separated at their outer ends by a spring 10 in the ordinary manner, said spring being mounted upon a sleeve surrounding the upper end of the bolt 3. A vibrating arm 11 is located intermediate of the handles 4 and 5 and is mounted upon the bolt 3, and its front portion is extended beyond the bolt 3 and is bent, as shown at 12, to enter a notch 13 in the reciprocating cutter 7, whereby positive connection is had between the movable cutter and its actuating means. The vibrating arm operates in a slot or opening formed in the rear portion of the casing, and its rear end is forked, as shown at 14, to receive a crank 15'at the end of a shaft 16, hearing a'gear-wheel17, said shaft 16 being journaled in the folded end of an arm 18, projecting from the inner side of the handle 4 and secured rigidly thereto. A curved rackbar 19 is firmly attached to the inner side of the operating-handle 5, and its toothed edge intermeshes with the cogs of the gear-wheel 17, whereby upon bringing the handles4 and 5 together the shaft 16 and crank 15 are rotated and impart an oscillatory or vibratory movement to the arm 11, whereby the movable cutter 7 is caused to reciprocate a number of. times. The number of reciprocating movements of the comb-cutter 7 will depend upon the relative diameter of the gear-wheel 17, the remaining parts being the same and the handles 4 and 5 receiving a like movement. In order .to reduce the friction, ballbearings 20 are interposed between the vibrating arm 11 and the parts adjacent to its fulcrum, as clearly indicated in the drawings.

The cutting apparatus receives a comparatively rapid movement upon operating the handles 4 and 5 in aleisurely manner, thereby enabling the operator to perform a given task with less fatigue than is possible by using that class of clippers in which the reciprocating cutter moves in unison with the operatinghandle and makes a complete stroke at each movement of the handle.

The bolt 3 is enlarged at its inner end, forming a shoulder which receives the ball-bearings 20 for the arm 11, and the latter is held in place by the sleeve 21 and nut 22 on the outer end of the bolt 3.

Having thus described the invention, what is claimed as new is 1. In ahair-clippin g machine, the combination with movable and fixed cutters, and stationary and movable handles, of an intermediate vibrating arm for actuating the movable cutter, an arm extending inwardly from the stationary handle, a gear-wheel mounted upon the inner end of said arm and provided with a crank having connection with said vibrating arm, and a rack-bar carried by and projecting inwardly from the movable handle, and meshing with they gear-wheel, substantially as specified.

2. In a hair-clippin g machine, the combination with fixed and movable cutters, and stationary and movable handles, of a vibrating arm located intermediate of the handles and having positive connection with the movable cutter, and having its outer or rear end forked or spread, an arm extending inwardly from the fixed handle, a gear-wheel journaled to the inner end of the said arm and having a crank connected therewith, and operating in the fork or separated portions of the vibrating arm, and a rack-bar projecting inwardly from the movable handle and intermeshing with the said gear-wheel, substantially as set forth.

3. In a hair-clipping machine, the combination with movable and fixed cutters, and stationary and movable handles, of a vibratory arm for actuating the movable cutter, a gearwheel carried by the stationary handle and having a crank operatively connected with said vibratory arm, and a rack-bar carried by the movable handle, and meshing with said gear-wheel, substantially as specified.

4. In a clipping-machine, the combination of a fixed and a movable cutter, a stationary and a pivoted handle, a vibrating arm intermediate of the handles and having positive connection with the movable cutter, and hav= ing itsouter end forked, an arm extending inwardly from the fixed handle and having its inner end folded, a gear-wheel journaled in the folded portions of the arm and provided with a crank to operate in the fork of the vibrating arm, and a rack-bar attached to the pivoted handle and inter-meshing with the said gear-wheel, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

ANDREW M. sins.
