HAIR CLIPPER.

Specification of Letters Patent.

Application filed May 27, 1921. Serial No. 472,979.

To aZZ whom it may concern:

Be it known that I, Fonnnsr FUGITT, a citizen of the United States residing at Chillicothe, in the county of Livingston and State of ll lissouri, have invented certain new and useful Improvements in Hair Clippers; and I do declare the following to be a full, clear, and exact description of the inventlon, such as will enable other skilled in the art to which it appertains to make and use the same, reference being had to the accompanying d 'awings, and to the figures of reference marked thereon which form part of this specification.

This invention relates to hair clippers and one of the objects is to provide means for providing an articulated joint between the.

clipper head and the handle with means for varying the angle of inclination of the head with respect to the handle so that the clippers may be easily manipulated in cutting hair at the back of the head, back of the ears and at the temples.

lin other words, it is thepurpose. of the invention to change the angle of the head portion with respect to the handle whenever desired to facilitate ease of handling the clippers when in use. i

The novel mechanism by which the de sired result is obtained will be apparent by reference to the following description in connection with the acompanying drawings, in which Fig. 1 is a perspective View of a hair clipper constructed in accordance with my invention.

Fig. 2 is a side elevational View of a clipper, parts being broken away.

Fig. 3 is a perspective view of the clipper mechanism.

Fig. at is a vertical, longitudinal, sectional view through a complete clipper, and

Fig. 5 is a top plan view of the operating mechanism.

Referring now to the drawings by numerals of reference:

1 designates a hollow handle which may be substantially rectangular and which is provided at its lower end with side bearings 2 and 3 and with a top guard flange i and a bottom guard flange 5.

Fixed in the bearing members and 3 is a transverse shaft 6, on which is pivotally mounted a block 7 having a segmental, cutout portion 8 to receive a drive shaft 9, one

end of which has a bearing in the shaft. 6, as at 10. The other end of the drive shaft e);- tends through the handle and it is shown as supporting bearings 11, 12 and 13 and adapted to be driven by a flexible connection 14, receiving motion from any suitable source. The shaft 9 carries a pinion 15, which rotates a gear 16, loosely mounted on the shaft 6 and driving a pinion 17 on a stub shaft 18 in the bearing plate 19, fixed to the bottom plate 20 rigidly secured to the block '7 by the fastening device 21.

The forward end of the bottom plate con stitutes a stationary cutter bar 22 provided with upstanding guides 28 and 524:, which project through the elongated slots 25 and 26 of a reciprocatory cutter bar 27, having an upstanding, channel-shaped member 28, into which is received an eccentricdisk 29 on the end of the shaft 18, so that when the shaft 18 rotates, a reciprocatory motion will be impartedto the movable cutter bar The mechanism for operating the cutter bar is not a part of this invention since the operation i of re-ziiprocatory clippers is well known.

The stationary plate 20 carriesa housing or guard 30, which encloses the operating mechanism and it is provided with an elongated slot 31. through which the shaft 9 extends, the slot and the cutout portion S being extensive enough to permit limited movement of the block 7 about the axis of the shaft 6, it being apparent by reference to Fig. 4 that the slot 31 will at all times be covered by the guards d and 5.

Means is provided for tilting the cutting head with respect to the handle and said means is shown consisting of lever operating mechanism, best shown in Figs. at and 5. /Vithin the handle 1 is a stud S2, to which is pivoted a T-shaped lever 33, having along arm 3 1- and two short arms 35 and 36. Projecting from the top of the handle are two rigid stop members 37 and 38, through which project the lever-actuatingrods or keys 89 and 40. The rod 39 is fastened to the end of the arm 35 and the rode-0 is fastened to the end of the rod 36. The rod 39 carries a collar 41 against which one end of a coil spring 42 bears, the other end bear.- ing against the stop 37 so that there is a normal tendency to press the key or rod 39 outwardly. A similar spring 43 has one end bearing against the top 38 and the other against a collar 414E on the rod so as to have a tendency to press the rod 4L0 outwardly in a direction opposite to that in which the spring 4C2 presses the rod 39.

The long arm 34: of the T lever is connected to the head 7 by: a link so that when pressure is applied against the key bottoms as and 47 to compress the-spring, the lever arm as will be swung away from the head 7 and, through the link connection, will swing the head together with the plate 20 and the mechanism carried by the head and plate in an upward direction at an angle, for example, as shown in Fig. 2. The angle of inclination will be determined by the extent of pressure exerted against the bottoms 1-6 and 4&7 so that any angle between two extremes may be had.

As soon asthe pressure is relieved from 46 and 47, the springs 42 and as will exert expansive force against the collars ll and a l so that the keys or rods will be pushed outwardly, swinging the arm 34 back to a substantially radial position, as shown in Fig. 5, so that the cutting head will assume the position shown in Figs. 1, 4c and 5 and,

therefore, it will be apparent that the angle of inclination of the cutting head with respect to the handle can be controlled through the keys formed by the push rods 39 and 40 and their abutments i6 and 47 during the operation 01 the machine because the fact that the machine is in operation will, in no wise, interfere with changing the angle of the head with respect to the handle. It will, therefore, be apparent that the hair cutting operation can be facilitated.

What I claim and desire to secure by Let ters-Patent is:

1. A hair clipper comprising a handle and a head, means for articulating the head to the handle whereby the head may swing on an arc with respect to the handle, means for determining the extent of movement of said head with respect to said handle, said means comprising manually actuated push rods,.

and connections between the push rods and the head.

2. A hair clipper comprising a handle and a head, means for articulating the head to the handle whereby the head may swing on an arc with respect to the handle, means for determining the extent of movement of said head with respect to said handle, said means comprising spring-pressed push rods, and connections between the push rods and the head.

3. A hair clipper comprising a handle and a head, means for articulating the head to the handle whereby the head may swing .on' an arc with respect to the handle, means for determining the extent of movement of said head with respect to the handle, said means comprising a lever within the handle, a push rod for actuating the lever, and a link connection between the lever and the head.

4;. A hair clipper comprising a handle and a head, means for articulating the head to the handle whereby the head may swing on an arc with respect to the handle, means for determining the extent of movement of said head with respect to the handle, said means comprising a pivoted T -shaped lever, oppositely functioning push rods connected to the head of the T-sha'ped lever, and a link connection between the long arm o1 the T- shaped lever and the head.

In testimony whereof I affix my signature.

FORREST FUGITT.
