A. C. LEIGH ELECTRIC RAZOR Oct. 18, 1938.

Filed March 17, 1937 y% BY Mmr ATTORNEYS Patented a. 1a, 1938 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to electric razors and has for an object to provide a razor having a circular slotted guard member and a disc cutter having an annular series of radially disposed teeth, the cutter being spring pressed into close engagement with the guard member so that hairs of the face may be intercepted by the disc cutter as the guard member is moved over the face and severed with great rapidity and ease, the circular shape of the guard member permitting of the razor being manipulated to more readily conform to the contours of the user's face than electric razors of the rectilinear blade type.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure 1 is a planview of the razor looking toward the guard member.

Figure 2 is a side elevation of the razor.

Figure 3 is an enlarged longitudinal section of the razor taken on the line 3-3 of Figure 1.

Figure 4 is a fragmentary detail section of the razor taken on the line 4-4 of Figure 1.

Figure 5 is a side elevation of the stationary cutter.

Figure 6 is a plan view of the guard member.

Figure 7 is a plan view of the cutter.

5 Figure 8 is a plan view of the razor showing the modified form of guard member.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, Ill designates a hollow grip handle having one end enlarged to provide a shell II the end edge of which is provided with an annular series of guard teeth I2.

The grip is provided at one end with an integral bearing l3 and within the shell a diaphragm 5 I4 is provided with a marginal flange I5 which is secured to the shell by screws IS. The flange is provided with a bearing H.

A shaft [8 is rotatably mounted in the bearings l3 and I1 and extends axially in the grip and 50 shell. The shaft is provided outside of the bearing I3 with a bushing I9 which is housed in a cap 20 that is screw threadedly engaged with the bearing I3 as shown at 2|.

The bushing is provided with a stub shaft 22 55 which may. be engaged with a conventional flexible shaft 23 by a tongue and groove joint 24. The flexible shaft may be driven by any conventional motor.

A disc cutter 25 is secured axially to the end of a stub shaft 26, best shown in Figure 3, by 5 means of a countersunk screw 2'! or other connector. The disc cutter is of suflicient diameter to nicely fit within the shell as best shown in Figure 4 and is provided with radially disposed slots 28, best shown in Figure 7, disposed very close 10 together and forming cutting teeth.

The stub shaft 26 of the cutter is housed within a hollow extension 29 of the rotary shaft l8 and is spring pressed outwardly by a helical spring 30 which is housed in the extension 29 in rear of 15 the stub shaft 26. A pin 3| is extended through the extension 29 and is engaged in a slot 32 formed longitudinally in the stub shaft 26 to connect the cutter for rotation as a unit with the rotary shaft I8 and also permit assembly 20 and disassembly of the cutter with the rotary shaft.

A disc guard member 33 is provided with a plurality of radially extending slots 34 which are arranged in close proximity with each other. The 25 guard member is provided with oppositely disposed tabs 35 which fit in notches 36 formed in the toothed edge of the shell as best shown in Figure 1. These tabs, as best shown in Figure 4, are directed downwardly along the outer face of 30 the shell II and are rigidly attached to the shell by screws 31 which are passed through slots 38 in the tabs and into the shell.-

The cutter 25 is yieldably held by the spring 30 against the guard member 33 so that when 35 hairs project through the spaces between the teeth 34 of the guard member they will be intercepted by the rotating teeth 28 of the cutter and rapidly severed close to the skin. By viirtue of the guard member being a disc having annular teeth, and by virtue of these teeth forming continuations of the teeth l2 of the shell, it will be evident that when the grip I0 is manipulated, over the face, it may be held at any desired angle to the face to permit the guard teeth l2 and the guard member to indent the skin which is elastic as is well known, and permit of a close shave being obtained regardless of how abrupt the contours of the user's face may be.

In Figure 8 there is shown a modified form of guard member 39 having teeth 40 extending parallel with each other from the edge of the guard member to nearly the center of the guard member, there being an imperforate portion at the bases of the teeth forming a bar 4|, which l5 shell, an annular series of rearwardly curved Y An electric razor comprising a hollow grip terminating in an enlarged extension forming a 2,1aa,eos

a disc guard member provided with an annular series of radially extending teeth at the ends forming continuation's o! the teeth of the shell, oppositely disposed tabs on the guard member fitting in notches formed in a toothed edge of the shell, the tabs being directed downwardly along the outer face or the shell, screws passed through the tabs and into the shell, a disc cutter revolubly mounted in the shell and spring pressed to contact its upper face with the lower face of the guard, and an annular series of radially disposed cutting teeth on the edge or the cutter adapted to coact with the teeth of the guard member.
