IMPROVEMENT |`N HAIR-CLIPPERS.

Specication formingpart of Letters Patent No. 216,998, dated July 1, 1879; application filed v March 8, 1879.

To all whom "it may concern:

Be it known that I, OYRUs GARLETON, of the cityand county of Providence, and State of Rhode Island, have invented certain new and useful Improvements-in Hair-Clippers;

rangement, combination, and constructionof the various parts, by which a new and superior machine is produced, and which will bev more fully described hereinafter, and pointed out in the claims.

Figure l is a top view of my improved clipper, adapted to be operated by one hand, the handles being provided with iin ger and thumb rests, so that the clipper can be firmly held and operated. Fig. 2 is a top view of the combplate and the cutter-plate, showing the lever operating the cutter-plate, the fulcrum of the lever, the spiral spring operating the lever by reaction, and the position of the two handlevers, the cap covering these parts in Fig. 1 being removed. Fig. 3 is a sectional view of Fig. 1 through the line A B, indicated on Fig.

2. Fig. 4 is a sectional vviewof Fig. 2 through the line G D. Fig. 5 is a rear-end view of the clfifpper, the hand-levers being shown broken o In Vthe drawings, c represents the combplate, provided with the comb-teeth b. These teeth are made of considerable depth, much greater than comb-plate teeth as heretofore made. The under surface from the front end of the teeth to the rear end is slightly curved, and the plate in the rear of the teeth diminishes rapidly in thickness, so much so that the teeth can pass into curved surfaces and cut the hair of uniform length in all parts. The teeth in the comb-plate are also much longer -the hair more firmly while the same are cut by the reciprocating cutter-plate.

As the long and slender comb-teeth wouldA be liable to break off at a slight touch, the temper of the forward portion is drawn to a spring temper, while the rear cutting portion is left sufficiently hard to present a `good cutting-edge. i

The comb-plate forms the base of the clipper, and all the parts are directly or indirectly secured to the same.

Figs. 1 and 2 show the outline of' the combplate, and Figs. 3 and 4 the varying thickness of theplate in section.

G represents the cutter-plate. -The central portion of this plate is cut out sufiiiciently, so as to give a narrow bearing C11 the front and rear edges of the-plate, both bearings extending the whole length-of the plate. d. d are two slots in the plate, and the pins d d', secured in the comb-plate, as shown in Fig. 2, pass through the slots d d in the cutter plate, forming guides for the plate and stops toY limit the reciprocation of the cutter-plate. The hole c, in which the cam on the lever, by means of which the cutter-plate is reciprocated, oscillates, is cut through the cutter-plate; but the segmental cutf removes only a portion of the upper part of the cutter-plate without disturbing the rear bearing of the plate, as has been the case with cutter-plates as heretofore constructed. This break in the bearing of the cutter-plate, within which the short arm of the lever heretofore moved, allowed hair and dirt to accumulate between the lever and the plate, and caused much wear and friction, all of which is avoided in my improved'clipper.

r)The xedllever g is secured to the combplate by means of two screws, as shown in Figs. 2 and 4, firmly holding the plate g1, forming part ofthe fixed lever to the comb-plate and to more rigidly hold the fixed lever to thecomb-plate, a' portion of the plate g extends downy even with the comb-plate, and fits closely to the edge of the same, as is shown in Figs. 3, 4, and 5.

The plate g1 is milled out to receive the operating-lever, and is partially surrounded with a raised rim, g2, from which the fixed Alever projects.

By this construction the upward curved portion of the {iXed and operating levers can be placed on the same height, be curved both in the same manner, exert the force on the same plan, and present a more elegant and finished appearance than when they are made to pass olle over or in front of the other.

is the axial fulcrum on which the operatin g-lever lis hinged. It is a stout pin, screwed into the comb-plate, and resting on the same by a projecting shoulder. rEhe operating-lever l is provided with the sleeve mf, which secures to it a long bearing on the pin i, and adds 'much to the accuracy of the working. Surrounding the sleeve m is the coiled spring u, one end of which is in contact with a pin on the short end of the lever l, and the other end rests against the end h of the rim g2. The whole is protected by the cover O, resting at h on the curved rim' g2, and bearing on the cutterplate C along the cutters, as is shown in Figs. 1 and 3. The pin t' projects'through the cover O, and is provided with a screw-thread. Awasher, p, is placed on the plate, made of spring-steel, and curved so that when the nut q is tightened the cover O, resting firmly at h, will exert a yielding pressure alongtheline of the cutters, and thus keep the same in contactwith the comb-plate, not fixed and rigidly, but yielding to the spring of the washer p.

All the parts yare protected by means of the cover 0, and hair or other impurities are not is also hinged on a long bearing and bears on the lower part of the pin, so that it is not liable to bind. The whole works accurately with the least possible friction, and the general appearance is elegant.

The hand-levers g and t are rounded on vthe outside, the ends curved inward, and'thumb f and' n ger rests are provided, to facilitate the handling of the'clipper without fatigue-an important point whendntended for barbers use.

Having thus described my invention, I

claim as new and desire to secure by Lettersv Patent- 1. In a hair-clippin g machine, the combination, with the cutter-plate C, of a comb-plate the forward portion of which is of greater thickness than the rear portion, and in which the lower surface of the forward portion is curved, and diminishes rapidly from the end of the teeth rearward, so that the teeth can enter irregularities in the surface and the hair can be cut uniform in length, as described.

2. The combination, with the comb-plate of a hair-clipper, of a lever provided with a curved rim or flange, which is 'arranged and adapted to inclose a portion of the clipper, and to form a bearing for the rear portion of the cover, substantially as set forth.

3. rI he combination, with the comb-plate and lever provided with a curved rim, which is arranged and adapted to support the rear end of the cover, of a fulcrum-pin secured at its lower end to the comb-plate, and its upper end connected with the cover, substantially as set forth.

4. The combination, with the comb-plate, cutter-plate, and lever provided with a curved rim which incloses a portion of the clipper, of an independent cover, the forward end of which rests upon the cutter-plate and its rear end upon the raised curved rim of said lever, and an operatinglever provided with an elongated sleeve-bearing, which surrounds the fulcrum-pin of the clipper, and provided with a cam for operating the cutter-plate, substantially as set forth.

5. The combination, with the comb-plate, cutter-plate, and lever provided with a curved rim, which incloses a portion of the clipper, of an independent cover supported atfopposite ends upon the cutter-plate and curved rim of the lever, an operating-lever provided with an elongated sleeve-bearing, which surrounds the fulcrum-pin, andv `a spirall spring surrounding the elongated sleeve, and adapted to move the operating-lever in one direction, when the same has been moved in the opposite direction by hand-power, substantially as set forth.

6. The combination, with theA comb-plate vand lever provided with a raised curved rim,

which incloses a portion of the clipper, and an independent cover, which is supported at opposite ends by the cutter-plate and raised curved rim, of a fulcrum-pin provided with a nut and spring-washer, substantially as set forth.
