SHAVER AND HAIR REMOVER Filed April 20, 1937 Gus fay Bin/9495072 ATTORNEY Patented June 14, 1938 UNITED STATES PATENT OFFICE 9 Claims.

The invention relates to a shaver and hair remover and more especially to a safety razor.

The primary object of the invention is the provision of a razor of this character, wherein interfitted relatively movable cylinders provided with slots when in motion will sever hairs for 1 shaving and hair removing purposes, the cylinders being rotatable reversely to each other in their interfitted relationship and also the innermost cylinder is reciprocatory and in this manner assures the positive shaving and hair removing operation in the use of the razor.

Another object of the invention is the provision of a razor of this character, wherein the same is roller acting so that it can be rolled over the skin for shaving and hair removing purposes and will not cut the skin during the use thereof and thus assuring safety against injury while in use.

A further object of the invention is the provision of a razor of this character, which is simple in its construction, thoroughly reliable and effective in operation, readily and easily handled,

positive in the working thereof, absolutely safe from cutting the skin during shaving or the act of removing hair from the human body, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is an end elevation of a razor constructed in accordance with the invention.

Figure 2 is an enlarged plan view partly in section.

Figure 3 is a sectional view taken on the line 3-3 of Figure 2 looking in the direction of the arrows; and

Figure 4 is an end elevation of the innermost cylinder of the razor and removed from the outer cylinder.

Similar reference characters indicate corresponding parts throughoutthe several views in the drawing.

Referring to the drawing in detail, A designates generally the razor constituting the present invention and comprises outer and inner cylinders l0 and II, respectively, these being formedwith circumferentially arranged elongated slots |2 adapted to register with each other and such slots in each cylinder are disposed close to each other so that when the said cylinders are rotated in opposite directions in their interfltted relation to each other a shearing or cutting action will be set up for shaving and hair removing purposes.

The outer cylinder III, which functions as a roller in the use of the razor, is of greater length than the inner cylinder H and has fitted in any suitable manner in opposite ends thereof, internal gears l3, while the opposite ends of the 10 inner cylinder II are formed with spokes I4 extending radially from end hubs l5, these being provided with pinions l6. Interposed between the gears l3 and the pinions l6 are idling gears these being enmeshed with the gears l3 and I pinions l6, respectively, so that the outer cylinder l0 under rolling contact with a surface will drive the inner cylinder H and these cylinders will rotate reversely to each other through the gear connections therebetween.

Bridging the outer cylinder I0 is a yoke frame I8 in which are removably carried stud journals l9, these having the hubs l5 Journaled thereon. Centrally of the frame I8 is a handle 2|), being fixed thereto in any suitable manner.

The gear lit in one end of the outer cylinder III has formed therewith an annular cam 2| coacting with an annular companion cam edge 22 at the end of the inner cylinder next thereto so that on relative rotary movements of the cylinders l0 and II these will be reciprocated with respect to each other. In other words, under the operation of the cams 2| and 22, companion to each other the inner cylinder- U will be reciprocated within the outer cylinder Ill. The bear- 35 ing ends 23 of the frame l8 for the stud journals I8 are outstruck to afford a clearance for the reciprocatory movement of the inner cylinder these stud journals l9 being slidably fitted in said bearing ends 23 in addition to the rotatable flt- 40 ting thereof. The gear l3 at the other end of the outer cylinder is formed with a retaining annulus 24 for the inner cylinder II and this annulus additionally constitutes a track for leaf springs 25 suitably fitted with the cylinder 45 the purpose of the springs 25 being for holding the companion cams 2| and 22 in contact with each other under reciprocation of the said inner cylinder ii and the relative reverse rotation of the outer and inner cylinders with respect to each other.

The idling gears H are separably journaled on the yoke frame It and are in meshing engagement with the gears l3 and the pinions I6.

Under rotation of the outer cylinder in by contact with a surface the said outer cylinder effects a driver for the inner cylinder ii and through the gearing connections between these cylinders one will rotate reversely to the other in the use of the razor.

The hair entering the slots in the cylinders l and II will be sheared or cut and there is no liability of the cutting of the skin during the use of the razor for shaving or hair removal.

The journals l9 are separably fastened in the hubs l of the inner cylinder II in any suitable manner.

During relative rotation of the cylinders l0 and H a reciprocatory action of the inner cylinder II is set up within the said outer cylinder 10 when the razor is in use so that in this manner cutting action takes place in paths at right angles to each other.

The gears IS in opposite ends of the outer cylinder II are held fast in place when within said cylinder in any suitable manner, it being necessary to remove one of the gears l3 when it is desired to extract the inner cylinder from the outer cylinder and, of course, the frame I8 is separated to allow for the separation of the said cylinders.

The spokes H support the inner cylinder II in conjunction with the hubs l5.

What is claimed is:

1. A razor of the character described comprising slotted interfltted relatively rotatable cylinders, gearing connections between the cylinders for reversely rotating the same with respect to each other, and means active between the cylinders for imparting reciprocation of one cylinder relative to the other.

2. A razor of the character described comprising slotted interfitted relatively rotatable cylinders, gearing connections between the cylinders for reversely rotating the same with respect to each other, means active between the cylinders for imparting reciprocation of one cylinder relative to the other, and a frame rotatably supporting the innermost cylinder.

3. A razor of the character described compris- Y ing slotted interfltted relatively rotatable cylinders, gearing connections between the cylinders for reversely rotating the same with respect to each other, means active between the cylinders for imparting reciprocation of one cylinder relative to the other, a frame rotatably supporting the innermost cylinder, and stud journals removably fitting the frame and rotatably connecting the innermost cylinder thereto.

4. A razor of the character described comprising slotted inter-fitted relatively rotatable cylinders, gearing connections between the cylinders for reversely rotating the same with respect to each other, means active between the cylinders for imparting reciprocation of one cylinder relative to the other, a frame rotatably supporting the innermost cylinder, stud journals removably fitting the frame and rotatably connecting the innermost cylinder thereto, and a grip medially of the said frame.

5. A razor of the character described comprising slotted interfltted relatively rotatably cylinders, gearing connections between the cylinders for reversely rotating the same with respect to each other, means active between the cylinders for imparting reciprocation of one cylinder relative to the other, a frame rotatably supporting the innermost cylinder, stud journals removably fitting the frame and rotatably connecting the innermost cylinder thereto, a grip medially of the said frame, and means active between the cylinders for maintaining reciprocal relation thereof with respect to each other.
