Patented Sept. 29. 1931 UNITED STATES JAMES E. CONNOLLY, OF BALTIMORE, MARYLAND SAFETY Application filed April 28,

The invention generally relates to safety razors of the type wherein is provided a guard and lat-her applying roller so mounted relatively to the shaving blade as to act in the twofold capacity of guarding the face of the user against cutting contact with the blade edge and to reapply lather to the face of the user, and the said inventionprimarily has for its object to provide a new and improved form of roller and a regulator associated with the roller and adapted to regu late the reapplication of lather and to cooperate with the said roller in holding and working the lather.

In its more detailed nature the invention seeks to provide certain new and useful improvements in the razor structure disclosed in Patent Number 1,651,917, issued to me on December 6, 1927, and resides in the provision of an improved form of guard roller and a regulator mounted with the said roller on the razor guard plate and cooperatively associated with the said roller in a manner for regulating and assistingin the reapplication of lather to the face of the user.

Other objects will in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends, the invention consists in the novel details of construction, combination and arrangement of parts, all of which will be firstfully described in the following detailed description, then be particularly pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure 1 is a perspective view illustrating the invention mounted on a razor of well known type.

In the drawings 1 designates the razor handle to which the clamp head is attached,

the said handle being provided with a threaded socket 2 to receive the threaded shank 3 of the-clamp head 4;.

' The guide lugs 5 of the clamp head pass through suitable receiving apertures in the guard plate 6 which is also provided with an aperture to receive the shank 3. Between the guard plate 6 and the clamp head 4 the usual double edged blade 7 is clamped in the manner illustrated in Figure 1 of the draw- 1H s.- A

' g ll of the above structure will be recognized as conventional and it is to be understood that while I have disclosed the invention as applied to this particular form of razorthe invention is not so limited in application and comprehends all structures coming within the scope of the appended claims,

The side edges of the guard plate are preferably cut out to provide opposed pairs of mounting lugs 8 adapted to receive t e trunnions 9 of a guard roller 10 at each edge of the said plate. The cut out portions of the plate 6 are deep enough to provide an apprec able space 11 between the roller 10 and adjacent edge of the said plate, the purpose for which will presently appear.

In the disclosure made in the drawings the construction of the razor head at each side of the medial line is identical. For this reason, in the remainder of the description, detailed reference will be made to one side only of the razor head.

The guard roller 10 is preferably rovided with a 'rooved face engaging sur ace, the grooves being arranged in reversed spirals 12 so as to diverge from or converge to a point intermediately of the ends of the said roller thus forming centrally disposed Vs 13, see Figures 1 and 16. If desired, instead of grooving the roller the same may be provided with outstanding spiral ribs or threads 14 as indicated in Figure 17.

In the space beyond roller 10 a regulator 15 is mounted and serves to provide a regulator space 16 between it and the said roller, see Figure 3.

To provide for proper adjustment of the regulator 15 so that the space 16 may be varied at will the arms or lugs 8 may be slotted as at 17 and friction springs 18 set in the regulator bar ends to frictionally retain the same at adjusted positions, see Figures 4 and 5.

If desired the lugs or arms 8 may be offset at 19 and 'ad'uster screws 20 threaded through the said 0 sets andswivelly connected as at 21 to the regulator bar 15, thus making it possible to move the said bar toward or from the roller by manipulation of the said screws see Figures 6 and 7.

In Figures 8 and 9 I have illustrated a still further modification of the regulator mounting in which the said regulator is in the nature of a plate 22 having trunnions 23 slidable in the lug slots and having a slotted car 24 adjustably=screw secured as at 25 to the guard plate. As is indicated in Figures 10 and 11 of the drawings this plate form of regulator may be still further modified and constructed with trunnions to enable it to carry a rotatable roller 26 and mount the same corelatively to the guard roller for lather reapplication regulating purposes. This roller may also be provided with reversely arranged V forming surface grooves preferably disposed opposite to those of the guard roller so as to coact as converging pockets to facilitate the drawing of the lather down through the regulator space 16 behind the roller 10.

If desired the regulator may be a stationary non-adjustable element as indicated in Figures 12, 13 and 14.

In Figure 12 the regulator is a simple rod shouldered at one end as at 27 to fit a receiving hole in one of thc lugs 8, and split shouldered at its other end to snap fit into a receiving hole in theother lug 8.

In Figure 13 the regulator is shouldered end mounted in one of the lugs 8 and is provided adjacent its other end with athreaded portion 29 to fit a threaded receiving bore in the other lug 8.

In Figure 14 the regulator is likewise equipped with a shouldered end to seat in one of the lugs 8, while the remaining end is cut off to lie flush with the outer face of the other In 8 and is removably secured to position by a hinged keeper plate 30.

As will be observed by reference to Figures 13 and 14 the fixed regulators may be provided with a longitudinal lather retaining groove 31 or spiral grooves 32 designed for the same purpose.

In Figure 15 I have illustrated a still further means of retaining lather on the regulator. In this form the regulator is formed at one edge with closely arranged pin mounted balls 33 and toothed at its other edge as at 34 to facilitate the retention of lather.

In operation, when the razor is drawn across the face in the shaving direction the guard roller will serve to guard the face against any other than shaving engagement by the blade and will simultaneously manipulate and invigorate the skin. Retractile movement of the razor head will cause a reverse rotation of the engaging guard roller which will cause collected lather to pass down between the roller and the regulator, or through the regulated space 16 and be reapplied to the face to lubricate the same during the next stroke of the razor. Y

This coo eration of the roller and regulator constructe in the various forms disclosed serves to work the lather and keep it in proper condition and makes it unnecessary to reapply lather to the face during shaving. By simply dipping the razor head into water the lather collected thereon is moistened and by further use of the razor is worked into condition by the guard roller and regulator equipment and automatically applied to properly lubricate the shaving act. The roller, of course, also serves to work the lather on the face and materially aids in softening stu born beards.

It will also be observed that the razor thus equipped may be divested of the blade 7 and the guard roller equipment utilized to massage the face or to efficiently apply facial creams or ointments to the skin, the peculiar construction of the roller greatly facllitating the working. of the cream or ointment into the skin and the stimulating of the nerves and tissues. I

If desired one of the rollers may be mounted in a yoke frame 35 carried by a head 36 havin a depending threaded shank 37 suitable or fitting the threaded socket of the razor handle so that the device may be used as a massaging implement. The frame is rovided with inturned trunnions 38 to fit enarged trunnion seats39 in the roller ends. The walls of the seats may be roughened as at 40. The provision of the enlarged trunnion seats and the roughened walls thereof serve to impart a vibratory motion to the roller as it is drawn over the skin, further facilitating its use as a massagin device.

A razor constructed as herein isclosed provides for efiicient manipulation of the skin to facilitate softening of the beard and assures a clean shave b reason of the fact that the shave is better In ricated, the lather con-' tinuously worked and reapplied to the face being shaved, and further provides for such a shave with the employment of a minimum of lather.

The guard roller bears all of the weight or pressure of shaving and relieves the skin of all irritating drag.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the novel details of construction, the manner of use and the advantages of my invention will be readily apparent to those skilled in the art to which it relates.
