RAZOR Filed June 9, 1956 Patented Oct. 19, 1937 UNITED STATES PATENT- OFFICE RAZOR Clyde J. Peak, San Francisco, Calif.

Application June 9, 1936, Serial No. 84,344

1 Claim.

This invention relates to a razor, and it is primarily an object of the invention to provide a device of this kind embodying a rotary blade operating by mechanical means and more particularly from the power shaft of an electric motor.

The invention also has for an object to provide a razor of this kind embodying a structure whereby one or more blades may be detachably held in working position.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved razor whereby certain important advantages are attained and the device rendered' simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to,describe-the same with reference to the accompanying drawing, wherein:-

Figure 1 is a view in side elevation with portions broken away of a razor constructed in accordance withan embodiment of my invention;

Figure 2 is aview in end elevation of the device as illustrated in Figure 1;

Figure 3 is a fragmentary vertical sectional view taken through the cutting mechanism detached from the motor casing;

Figure 4 is a view in top plan of the structure as illustrated in Figure 3;

Figure 5 is a fragmentary elevational view of a coacting block plate and end plate of the cap member. A

As disclosed in the accompanying drawing, C denotes a casing for an electric motor, said motor in its entirety being of a size which can be readily held by the hand of a person grasping the handle H secured to and extending outwardly from they casing C. The electric motor is of a conventional type and is adapted for connection with a suitable source of electrical energy through a conductor a. and which operating circuit is under control of a,switch having an 'operating member I extending exteriorly of the casing Cand in such position with respect to the handle H to be readily engaged and operated by a digit of the hand grasping the handle H.

The motoralso comprises in its construction a drive shaft 2 having an extremity extending beyond an end of the casing C and which extended portion has mounted thereon for rotation therewith a pulley 3.

Disposed transversely across the periphery of the casing C is a block or saddle 4, the under face of which being of such formation and design as to have close contact with the peripheral face of the casing. I

This block or saddle 4 is fixedlysecured to the casing C by the bolts 5 or otherwise as may be preferred. The opposite end portions of the block or saddle 4 have extending upwardly therefrom the transversely disposed plates 6, each of which in its central portion having a cut out portion I which partially receives a bushing 8.

Rotatably disposed through the bushings 8 are the extremities of a shaft 9, one end portion of which extending beyond its adjacent plate 6 andhaving fixed thereto for rotation therewith a pulley ID. This pulley ID as herein disclosed is in driven connection with the pulley 3 by an endless belt H; Normally the pulleys 3 and I0 and belt II have disposed thereover a guard housing I! suitably anchored, as at M, to the adjacent end of the casing C and, as at l5, to an end plate iii of a cap member M. The lower edge of each of the plates l6 of the cap, member M contacts from above with the upper edge of the plate 6 and the lower marginal portion of each of the plates I 6 is provided with a cut out portion I! which registers with the cut out portion of the adjacent plate 6 and which accommodates a part of a bushing 8;

The upper and outer portions of the plates N5 of the cap member M are connected by the side strips l8, said strips having their outer faces converging on predetermined angles ward the top of the end plates l6, and the upper marginal portions of these strips iii are continued by the inwardly disposed top plates 19. The inner marginal portions of these top plates l9 are spaced apart and are provided along their upper faces with the relatively broad rabbets or grooves 20. The inner wall 20: of one of said rabbets or grooves is curvedin a cross section to closely conform to the cutting edge portion 20" disposed along each longitudinal marginal portion of the blade B. A second blade B is positioned within the second rabbet or groove 20 and both the blades B and B areof widths to have cutting edges overlying the space between the top plates IS. The blade B is of a reversible type while the blade B has its cutting edge preferter advantage with a beard which is particularly tough. I

The shaft 9 has disposed therealong the series of spiral blades 22 equidistantly spaced around the shaft 9 and herein disclosed as four in number. These blades each extend along the shaft 9 for a distance substantially, equal tothe space between the bearings 8 and the pitch of each of the blades 22 is such as to extend substantially one-half around the shaft 9 from one end of the blade to the other. v,

' When the razor is in use the motor operates to rotate the shaft 9 at a desired speed and as a result of such rotation there is a rolling travel at all times of an outer edge of a blade 22 along the working cutting edge 20" of the blade B and each of the blades 22 is of a width to bring its outer edge in close proximity to the cutting edge of the blade B as well as the serrated edge of the second blade B. The inner surface of the cutting edge portion of each of the blades B and B' is rounded on a radius closely approaching the radius of rotation of the outer edges of the blades 22.

The handle H is preferably in screw or o'then' detachable engagement with the casing C so that said handle can be removed when desired to facilitate packing the instrument in its entirety working position by the elongated screw mem-- within a small space. It is also believed to be without the handle H.

From the foregoing description it is thought to be obvious that a razor constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed. I claim:-

An electric razor comprising an electric motor including a casing and a shaft extendingoutwardly of said casing, a handle secured to and extending outwardly of the casing at right angles to said shaft, a block secured to said casing diametrically opposite from said handle, parallel plates secured at their inner ends to the ends of said block, a second shaft journalled in said plates and parallel to said motor shaft, a drive ,means connecting said shafts together, a slotted flat plate secured to the outer ends of said plates,

said slotted plate having recesses on opposite sides of the slot therein, a stationary cutting blade engaging in one of the recesses of said slotted plate, aguard engaging in the other recess of said slotted plate and disposed with an edge thereof in spaced relation to said cutting blade, and a rotary blade member secured to said second shaft and coacting with said stationary blade to cut hair engaging therebetween.
