12/ /7 Y I a @1170 V7. JOHNSON, OF CHICAGO, ILLINOIS.

HABR=OLEPPER;

Specification of Letters Patent.

Patented March. 27, 190L' Application filed October 9 1905, Serial No. 281,919.

To all whom it um z concern:

"Be it known that I, (h re W. JOHNSON, a subject of the King of Sweden and Norway, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Hair-Clipper, of which the following is a specification.

This invention relates to improvements in a device for cutting or clipping hair, andwhile it is more especially intended for shearmg purposes and toruse by barbers, as in trimming of cutting the hair on the human 1 rious head or face, yet it is applicable for use in horse clipping purposes; and it consists in certain peculiarities of the construction, novel arrangement, and operation of the vaarts thereof, as will be hereinafter more ully set forth and specifically claimed.

The principal object of the invention is to provide a hair-clipping device which shall be simple and inexpensive in construction,

strong, durable, and easily operated, and so i made that its parts may be readly assembled or separated for repairs or for sharpening the teeth of the shearing blades or plates. Other objects and advantages of the invention will be disclosed in the subjoined description and explanation. In order to enable others skilled in' the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in which I Figure 1 is a central vertical sectional view through the body ofthe clipper, showing the handles for holding and operating the same in elevation. Fig. 2 is a view in front elevation of the lower portion of the body, Fig. 3 is a detached side viewof the housing for the opera'tive parts of the reciprocating toothed plate. Fig. 4 is a detached plan view of the toothed blades or plates. Fig. 5 is a similar view of the bottom or stationary toothed plate; and Fi 6 is a view in front elevation of the toothed plates, showing the means for reciprocating the u per one.

Like numerals 0 reference refer to corre sponding parts throughout the different views of the drawings.

The reference-numeral 1O desi nates the body or supporting portion of the clipper, which is elbow-shaped and has in its rear portion a recess or cut-out part 11 for the recaption and operation of certain ears used for reciprocating the upper toot ed plate. This recess is closed by a cap 12, which is se cured to the body 10 by means of screws 13', which pass through its sides into suitable openings in the sides of the body. Above the recess 11 the upright portion of the body 10 isprovided with a cut-out portion 14, in which is located a beveled gear 15, which is riounted on a shaft 16, vertically journaled in the body and extending into the recess 11,

as is clearly shown in Fig. 1 of the drawings. Secured to the upri ht-portion of the body 1.0 are rongs 17 anc 18 of a handle 19, used for ho ding the device. Journaled on -one side of the upright portion of the body is a beveled gear 20, which is provided, with a crank-handle 21, used for turning the same. Mounted on the lower end of the shaft 16 is a beveled gear 22, which meshes with a like gear 23 on the inner end of the driving-shaft 24, which extends longitudinally through the lower portion of the 'body' and has on its front end a disk or wheel 25, which carries a wrist-pin or projection 26, which is eccentrically located on the front face of saiddisk.

Secured to the front portion of the lower part of the body 10 and extending forwardly therefrom is a casing or housing 27, the bottom of which is open. The front wall of the housing 27 is provided with two downwardlyprojecting ins 28, which extend through transverse s ots 29 in the reciprocating plate 30 and into openings 31 in the fixed plate 32 near their toothed edges. Both of the

plates

30 and 32 are provided at their front edges with a series of cuttingteeth 33, and the lower or fixed plate 32 has in its rear portion openings 34 for screws used to secure it to the bottom of the front portion of the body. When thus secured, it is apparent that the teeth 33 of said plate will project beyond the front wall of the casing or housing'27 and that a slight space will be left between the lower ed e of said wall and the upper surface of the p ate for the reception and operation of the movableplate 30, the teeth 33 of which will project forwardly from the front wall of 30,has near its niiddle a longitudinal slot 35,

through which is passed, as well as through an opening 36 in the lower plate, a bolt 37 the upper end'of which passes through an opening in the front portion of the casing 27 i and is securely held in place by means of a nut 38 thereon. Inwardly from the slot 35 the plate 30 is provided with two uprights 39, which are spaced apart in parallelism and receive between them the Wrist-pin 26 on the lOO eiazet the upper surface of the lower plate, and as said plates are pushed forward into the hair the same will be readily clipped or cut.

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

1. In a hair-clipper, the combination with a supporting-body, of a handle secured thereto, a crank-handled gear jonrnaled on the upper portion of the body, a driving-shaft journaled on the lower portion of the body, gearing connecting the inner end of said shaft to said gear, a guard or lower plate fixed to the lower portion of the body and projecting forwardly beyond the same, an upper or cutting plate movable transversely on the lower plate and having a pair of parallel uprights, and a disk on the front end of the drivingshaft having a wrist-pin to coact with said uprights to reciprocate the upper plate, sub stantially as described.

2. In a hair-clipper, the combination with an elbow shaped body having in its rear lower portion a recess, of a supporting-handle secured to the upper portion of the body, a crank-handled gear journaled on the upper portion of the body, a driving-shaft ]O11lnaled on the lower portion of the body and I having its rear end extending into said recess, a shaft vertically journaled near the rear end of the driving-shaft, a beveled gear on the drivin -shaft and a similar ear on the adjacent end of the vertical shaft, another gear on the vertical shaft to mesh with the crank-handled gear, a guard or lower'plate fixed to the lower 1portion of the body and projecting forward beyond the same, an upper plate movable transversely .on the lower p ate and having a pair of parallel uprights, a disk on the front end of the drivin shait provided with a wrist-pin tocoact with said uprights to reciprocate the upper plate, and a casing inclosing the disk an uprights and secured to the front portionof the body, substantially as described.
