HAIR-CLIPPER.

SPEGIFIGATION forming part of Letters Patent No. 736,854, dated August 18, 1903.

Application filed March 3 1903. Serial No. 146,011. (No model.)

as will enable others skilled in the art to which it appertains to make and use the same, ref erence being had to theaccompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in hair-clippers, my object being to provide a construction capable of increasing the relative action of the movable cutting-plate for a given movement of the handle or actuatinglever. The movable plate is provided with a slot extending at right angles to its direction of movement. This slot is engaged by a pin made fast to a crank or to a disk outside of its center, the disk or crank being fast on a spindle provided with a pinion engaged by a segmental gear with which the short arm of the actuating-lever is provided. The arrangement is such that the movement of the lever in either direction imparts a complete reciprocation to the movable plate or double the ordinary action for a given movement of the lever. I

Having briefly outlined my improved construction, as well as the function it is intended to perform, I will proceed to describe the same in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof. 7

In the drawings, Figure 1 is a top or plan view of my improved device. Fig. 2 isa top view shown on a larger scale with the top housing removed and the handles broken away. Fig. 3 is a side view of the device. Fig. 4 is a sectiontaken on the line 4 4, Fig. 2* Fig. 5 is a detail View of the movable cutting-plate. Fig. 6 is an underneath view of the actuatingdisk.

The same reference characters indicate the same parts in all the views.

Let the numeralo designate'the bottom or bed-plate provided with cutting-teeth cooperating with the teeth of the reciprocating plate which project upwardly through slots (i formed in the plate 6 and extending in the direction of its movement. The slots are of sufficient length to allow the plate 6 the necessary movement in the performance of its function.

On top of the lugs 7 is placed a bridgepiece 8, and above this plate is placed a U- shaped part 9, whose extremities are bent outwardly to engage the ends of the bridgepiece. The parts 8 and 9 are secured to the lugs 7 by screws 10. The lugs, together with the parts 8 and 9, may be said to constitute a bracket mounted on the bed-plate. J ournaled in the parts 8 and 9 of this bracket is a spindle 12, and fast on this spindle between the parts 8 and 9 is a gear or pinion 13. Made fast to the lower extremity of the spindle is a disk 14, concentric with the gear. Outside of the center of this disk is made fast a depending pin 15, which projects into a slot 16, extending at right angles to the slot 6. (See The equivalent of this construction would be a crank-arm fast on the spindle and provided with a pin projecting into a slot of the reciprocating plate.

In counterpart grooves formed in the plates 5 and 6 are located ball-bearings 17, while in the upper portion of the plate 6 are formed grooves in which are located bearing-balls 18, which are. also engaged by the lower front edge of the housing 19, which is held in place by a thumb-nut 20, screwed upon a post 21, whose lower extremity is made fast to the rear part of the bed-plate. The rear extremity of the housing 19 is bent downwardly and forwardly, as shown at 19, and rests upon the casing 22, in which a coil 23 is inclosed.

. This spring is engaged by a shoulder on the Assuming that the pin of the disk or crank is in the position indicated byl in Fig; '5, when the inward movement of the long arm of the lever commences the pin will move the cutter-plate 6 toward the right during a quarter of a revolution, or until the pin reaches the position 2, after which it will move the plate in the opposite direction until the pin reaches the position 3 in Fig. 5. Then as the lever is released the spring 23 reverses the action of the lever and gives the cutter-plate another reciprocation, as will be readily understood.

The handle 25 of the device is relatively stationary, being secured to the part 22, carrying the spring 23. The part 22 is made fast to the bed-plate in any suitable manner.

From the foregoing description the use and operation of my improved device will be readily understood and need not be further explained in detail.

Having thus described my invention, what I claim is 1. In a hair-clipper, the. combination of a bed-plate, a reciprocating plate, a handle fixedly secured to the bed-plate, and a handle pivotally connected with said plate, the bedplate having separated guide-lugs projecting through slots formed in the reciprocating plate parallel with its direction of movement, a bridge-piece connecting the said guide-1n gs, a U-shaped part attached to the top of the bridge-piece, a spindle journaled in the U- shaped part and the bridge-piece, a disk made fast to the spindle below the bridge-piece and provided with a pin located a suitable distan ce from its center, said pin engaging a slot formed in the reciprocating plate at right angles to the direction of the latters movement, and a pinion fast on the spindle between the bridge-piece and the U -shaped part, the pivoted handle having a gear meshing with the said pinion.

2. In a hair-clipper, the combination of a bed-plate, a reciprocating plate, a handle fiX- edly secured to the bed-plate, and a handle pivotally connected with said plate, abridgeshaped bracket mounted on the bed-plate, a spindle journaled on the said bracket, a disk made fast to the spindle below the top of the bracket and provided with a pin located a suitable distance from its center, said pin engaging a slot formed in the reciprocating plate at right angles to the direction of the latters movement, and a pinion fast on the spindle above the top of the bracket, the piv-' a bridge-shaped bracket mounted on the bedplate, the cutter-plate being open to receive the bracket and permit reciprocation with the last-named plate, a spindle journaled in the bracket, a crank-pin connected with the spindle and engaging a slot formed in the reciprocating cutter-plate at right angles to the direction of its travel, a gear fast on the spindle below the top of the bracket, and a gear made fast to the operating-lever and connected in operative relation with the gear of the spindle.

4. In a hair-clipper, the combination of a bed-plate, a reciprocating plate, ball-bearings interposed between the two plates to reduce friction, a housing extending above the reciprocating plate and suitably connected with the bed-plate, ball-bearings interposed between the front edge of the housing and reciprocating plate, the bed-plate being provided with upwardly-projecting lugs adapted to engage slots formed in the reciprocating plate and extending parallel with the movement of the latter, a bridge-piece connecting the two lugs, a spindle journaled in the bridge-piece, a disk fast on the lower extremity of the spindle and provided with a pin located outside of the center and engaging a slot formed in the reciprocating plate and extending at right angles to the movement of the latter, a pinion fast on the spindle above the bridge-piece, a lever fulcrumed on the bed-plate and having a gear meshing with the spindle-pinion, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
