JOHN WV. EISENHUTL OF SAN FRANCISCO, CALIFORNIA.

HAIR-CUTTER.

SPECIFICATION forming part Of Letters Patent N0. 402,727, dated May 7', 1889. Application filed September l2, 1888. Serial No. 285,259. (No model.)

To @ZZ whoml it may concern:

Be it known that I, JOHN W. EISENHUTH, of San Francisco,in the county of San Francisco and State 0f California, have invented anew and Improved Hair-Cutter, of which the following isa full, clear, and exact description.

My invention relates to an improvement in hair-cutters, and especially to an improvement upon an application for a similar device filed by myself June 2, 1888, Serial No. 275,806, and has for its object to simplify the construction and provide a more efficient means of adjusting the blades and manipulating the same.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying` drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a central vertical section. Fig. 2 is a plan view. Fig. 3 is a similar view with the cover removed. Fig. 4 is a plan view of a portion of the frame. Fig. 5 is a plan view of the bottom cutter, and Fig. 6 is a similar view of the top cutter, and Fig. 7 is aplan view of the adjusting-cap.

In carrying out the invention the frame AY consists of a handle, a, shank, a', and body portion, a2, the latter being incased, except at the outer end, by a detachable cover,A', the space between the cutters and the lower front end of the cover being closed by a shield, A2.

T he under surface of the body is stepped, as shown in Fig. l, consisting of a horizontal forwardlyextending member, b, a second horizontal rearwardlyextending member, b', above the plane of the first member, the two members being connected by an inclined surface, b2. The member h, from a point at or near the center, is out to produce a series of teeth or fingers, b3, adapted to be passed through the hair, and beyond which the hair to be cut projects.

The cutters B and B consist of thin plates of steel provided with a series of integral teeth, e. The bottom plate, B, which is flat,

is provided in the body, or that portion to the rear of the teeth, with two central aligning apertures, e and e2. The said bottom plate is purposed to rest loosely upon the member b of the frame, the teeth or fingers projecting over the teeth or fingers of the said member.

A post, E, threaded at the top and bottom, is screwed into the aperture e', and extends vertically upward through the cover. A second post, E', passes loosely through the rear apertures, e, to a firm attachment with the frame member b. This second post, which is perpendicular, terminates within the frame a distance below the cover, as best shown in Fig. l, and upon the upper end thereof a spurwheel, E2, is horizontally keyed or otherwise secured, having attached to the upper surface a bevel-pinion, c3.

The upper cutter, B', is adapted to the bottom stepped contour of the frame, consisting of an upper and lower horizontal member, d and CZ', connected by an inclined surface, d2, as best shown in Fig. 1. The member d is provided with the usual teeth or fingers-as aforesaid, and slightly to the rear of said tingers a transverse segmental slot, d4, is produced, through which the forward post, F, passes, and to the rear of said slot d4 an aperture, d5, is formed for the reception of the rear post, E'.

In the upper horizontal member, d', an essentially diamond-shaped opening, d6, is out, and through the center of said opening a perpendicular spindle, D, is passed, having the lower end rigidly attached to the frame and the upper end iitted in the cover.

A pinion, D', is held to revolve around the spindle D, provided upon the under surface, which is immediately over the cutter B', with an attached washer, D2, and a pin, D3, extending vertically downward from the washer intoy the opening d of the upper cutter, engaging the walls thereof. The pinion D' meshes with the spur-wheel E2, and is held in connection with the cutter by a spring, k, coiled around the spindle D, bearing upon the upper surface of the pinion and against the cover.

It will be observed that as the lower cutter is stationary when the pinion D' is revolved the pin D3 has a cam-like action upon the upper cutter, imparting a reciprocating rotary movement, whereby a clear out is obtained.

The outer end of the cutters, and likewise the finger end of the frame, are preferably IOO made seinicircular, and if in practice it is found desirable the washer D2 may be dispensed with and the pin D3 be secured directly to the pinion.

The cutting-blades are adjusted with relation to each other by a semicircular cap-plate, K, having a flange, k integral with the outer upper surface, as best shown in Figs. 1 and 7. The adj ustingcap K rests upon the upper cutter, and is provided with an aperture, 7L, to accommodate the forward post, E. The post E is encircled by a sleeve, H, resting upon the cap K. and extending upward to the threaded surface of the post, as seen in Fig. l, a winged nut, 7L', being screwed upon the post to a bearing upon the sleeve, and a janinut, h2, is made to bear upon. the said winged nut. By manipulating the winged nut the cutting-blades may be vbrought as close together as desired.

The two cutters are carried to or from the fingers of the frame to cut the hair at various lengths by a thumb-lever, M, fulerumed in the shank of the frame, one end whereof extends beneath the handle, the other end being made to encircle the sleeve H and rigidly held between the winged nut 7L and a ange formed upon the collar.

The lever M is manipulated through the medium of a push-button, M, attached to the rear end of the lever M by a rod, m, pivoted to the lever and passing up through the shank near the handle. The button when pressed is restored to its normal position by a spring, m', encircling the rod and bearing, respectively, upon the shank and against the button.

The spunwheel E2 and pinion cB are re volved from a shaft, N, j ournaled horizontally in the frame, provided with a crank, N', at the outer end and a bevel-gear, N2, upon the inner end,meshing with the bevel-pinion e3.

The opening between the front lower end of the cover and the cap located upon the plate is closed by a shield, A?, as above stated, and as the said shield conforms to the con tour of the front of the frame loose hair is prevented from finding its way into the inte rior of the body-frame. The shield is held in position by a spring, T, bearing upon the top thereof and against the cover A. Instead of operating the shaft N by means of the crank N', it (the crank) may be dispensed with and a grooved pulley placed upon the end of saidY shaft N, which may be connected by a flexible belt with the drive-wheel of any suitable electric or other motor.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with. a body provided with a series of fingers at its lower outer end, a cutting-plate held laterally secure above the fingers, and a second upper rotary reciprocating cutting-plate, of a post passing through the upper plate and secured to the lower plate, a sleeve surrounding the post, bearing upon the upper plate, an adj Listing-nut in contact with said sleeve, and a lever fulcrumed upon the body and attached to the post, substantially as shown and described.

2. The combination, with the body provided with attached fingers, a cutti 11g-plate held laterally secure above the frame, a second cutting-plate held to rotary reciprocation upon the first plate, and provided with an essenh tially diamond-shaped opening removed from the cutting-edge, of a spindle attached to the body, a pinion loosely mounted upon the spin dle, provided with a pin eccentric upon its under face engaging the walls of the plateopening, a shaft journaled horizontally in the body, and gearing,substantially as shown and described, connecting the pinion and shaft, substantially as specified. p

3. The combination, with. a body provided with a series of fingers at its lower outerend, a cuttingplate held laterally secure above the fingers, a second upper cuttingsplate held to rotary reciprocation upon the first plate, and a cap resting upon the movable plate, of a vertical post passing through the cap and upper plate and attached to the lower plate, and of a sleeve encircling the post, an adj usting-nut bearing upon the sleeve, avertical shield supported upon the cap, and a lever attached to the post fulcruined in the body, substantially as shown and described.

4. The combination, with a body provided with a series of fingers, a cutting-plate held laterally secure above the fingers, a second upper cutting-plate held to rotary reciprocation upon the first plate and having an essentially diamond-shaped opening removed from the cutting-edge, a cap lresting upon the upper plate, a vertical post passing through the cap and upper plate and attached to the lower plate, and a shield supported upon said cap, of a sleeve encircling the post, an adjusting nut bearing upon said sleeve, a lever fulcrumed in the body and engaging the post, a pinion provided with a pin eccentric upon the un der surface, engaging the walls of the plateopening, a shaft journaled transversely in the body, and gearing, substantially as shown and described, uniting the said shaft and pinion, as and for the purpose specified.
