EDGE TOOL DEVICE Filed Dec. 2'7 1941 INVENTOR.

4142/54 Jf/Z/w/wm Patented Feb. 22, 1944 UNITED STATES I PATENT OFFICE EDGE TOOL DEVICE Earl Edward Hindman, Washington, D. 0.

Application December 27, 1941, Serial No. 424,657

7 Claims.

The invention relates to cutlery devices,-and particularly to means adapted to be embodied in safety razors, scrapers, and other tools, incorporating means in the tool to function as a receptacle or receiver for lather and shaved hairs or other detritus,so that dropping of lather upon the person of the user or upon other objects and surfaces is minimized.

A further important aim is to so construct a lather receptacle and tool mount that the article may be readily cleaned and cleared of all accumulations. Another important aim of the invention is to provide a mount adapted to use with a well known construction of safety razor guard or comb portion, so as to cooperate therewith to receive and hold lather passingover the edge of the blade during shaving operations.

Additional objects, advantages and features of invention reside in the construction, arrangement and combination of parts involved in the embodiment of the invention, as will be more readily understood from the following description and accompanying drawing, wherein Figure l is a view partly in cross section of a razor head embodying my invention, in closed position, the blade being omitted, and the lower part of the handle being broken away, doubled in size. I

Figure 2 is a similar view with the parts in open position.

Figure 3 is an elevation of the article as viewed from the right hand side of Figure 1, approximately actual size of the article as used.

Figure 4 is a horizontal section on the line i5l'5 of Figure 2, actual size.

There is illustrated a development of the in-' vention applied to a well known commercial type of razor, so constructed that a blade may be clamped therein without detachment of any of the parts of head or clamping elements.

This well known razor, now largely sold upon the market, includes a guard and blade support member 50, of rigid construction, and fixed upon a support body 51, which, in the present instance, is extended as a handle I5. Through this support 51a plunger 52 is longitudinally reciprocable, carrying a frame work 53 which includes a central bar, fixed at right angles across the outer end of the plunger 52, the frame including also lateral arms 54 at each side upon the inturned reduced ear portions 55 of which clamping yokes 56 are pivoted. Each yoke 56 includes a top clamping plate 51 adapted in one position of the device to lieclosely over the guard 50 so as to presses, razor blade of the Gillette type downwardly upon the guard and flex the blade to the familiar form which the guard causes it to assume, the clamp plates being curved and adapted to press the outer longitudinal edge portions of the blade downwardly around a corresponding curved part of the guard, so that the blade edges are exposed properly for shaving operation upon the face of the user, as is generally well understood in the art. The yokes include arms 58 at each end lying outwardly of the ends of the guard 55), and the guard at each end is provided wth longitudinal outwardly projected lugs 59, beside which the arms 58 may reciprocate in the movement of the frame with V the plunger 52. The arms 58 are provided with heel portions 60, projected laterally of the razor head beneath the lugs 59, so that as the frame is moved outwardly with the plunger 52, the heel portions will strike the lugs 59 and cause the clamp plates 55 to swing outwardly to the position shown in Fig. 13. The moving frame 53 on the plunger 52 is the means for drawing the clamping plates into snug engagement with the razor blade laid over theguard 50, and the frame is in its lowermost position when so engaged with the razor, as shown in Figure 1, or nearly so, depending upon the thickness of the razor blade. In its elevated position, the'frame is raised so that the clamp devices 56 are elevated above the guard, and in movement to this position, after the heel portions 60 have engaged the lugs 59 and moved the clamp devices outwardly a distance, the article being held with the plunger 52 on a vertical axis, gravity will draw the clamp devices 58 further outwardly, until they fall to full open position, with'the arms 58 of the clamp devices resting upon the upper side of the lugs 59, as shown in Figure '2. The moving frame 53 on the plunger includes parts slidable through the guard 55 so as to hold the frame and plunger against rotation relatively to the guard on the axis of the support 5| and guard. In this type of razor as heretofore produced a rotating knob on the end of the conventional handle is so engaged with the reciprocating element corresponding to the plunger 52 here shown that the reciprocating element is moved longitudinally outward upon rotation of the knobin one direction, and is retracted upon rotation of the knob reversely.

In my invention the support 5| instead of being formed like a handle in itself, is formed with a short externally threaded tenon 6i, and the plunger 52 extended downwardly a distance beyond this tenon, the outer end portion of the plunger having screw threads formed thereon,

Otherwise, the parts of the prior commercial article mentioned are retained in substantially identical construction as heretofore produced and well known.

In the present instance, I have a ferrule 62 of cylindrical form screwed upon the tenon 5|, and having a reduced bore 63 therethrough, forming a shoulder 64 adjacent the end of the tenon, but spaced from the tenon when the ferrule is screwed snugly againstthe under side of an enlargement 65 formed on the support 5|. Held revolubly in the ferrule, there is an operating sleeve 66 having a flange 61 at its upper end by which it is held against longitudinal movement in the ferrule, this flange being fitted revolubly between the shoulder 65 and the adjacent end of the tenon 6!. The sleeve is interiorly threaded and engaged upon the threaded extremity of the plungers 52, so that rotation of the sleeve 65 will cause longitudinal movement of the plungers 52. To accommodate the threaded portion of the plunger, the sleeve is formed of a piece bored and tapped, the bore being of a sufficient depth to leave a clearance between its inner end and the extremity of the plunger 52 when the latter is in its lowered position, as may be clearly seen in Figure 1. The sleeve 65 is provided with a longitudinally extended portion of reduced diameter, formed with anchor flukes or lugs 69 projected laterally therefrom, and this extension 58 is embedded in the molded plastic material of the handle l5, which may be transparent, translucent, or otherwise.

From the last given description, it will be apparent that by grasping the ferrule 52 between the thumb and forefinger of one hand, while the transparent cover of my illuminating device is rotated, the plunger 52 will be caused to move outwardly from the position of Figure 1, or inwardly from the position of Figure 2, to enable use of the razor head in the way familiar in the use of the beforementioned well known commercial razor device.

In accordance with my invention, the enlargement 65 is principally in the form of wing-like cam flanges, the lower sides of which may be of any convenient or symmetrical shape, while the upper sides are concavely curved, as shown in Figures 1 and 2. Respective cup devices Ill of elongated form are arranged under respective sides of the guard and pallet member. The latter, as customary, is formed with a rectilinear lower edge II, on the guard portion proper, the adjacent edge portion bein extended downwardly near, if not quite, parallel to the axis of the mounting, the mounting in the present instance comprising the support3 l, the ferrule 62 and any additional parts incorporated thereon. Each cup is provided with a corresponding rectilinear upper edge portion 12, adapted to lie in snug fitting abutting engagement with the edge ll of the guard, respectively, and a front wall portion of the cup 13 is extended downwardly therefrom as viewed in Figure'l, being inclined inwardly toward the axis of the mounting with a gradual curve for a short distance. Each cup is provided with inner wall portions 14, forming the inner side of the cup, and, formed integrally with the two walls, there is an end wall 75 at each end, the two walls 15 being parallel to each other, and having portions extended obliquely above a line from the edge 12 to the top of the wall '14, and also extended in the general upward direction of the wall 14 for a distance, to form pivot ears 16, which are continuations of the walls l5. The cups are mad of alength somewhat greater than that of the guard 50, and may be also made of a length equal to the distance between the outer faces of the arms 54 at one end and corresponding faces of the arms at the opposite end of the head of the razor. This permits the cars 16 to be pivoted on the outer sides of the arms 54, by means of fixed pintles or rivets 11, shown in Figures 1 and 2.

The walls 14 are fiat for the major portion of their length, and so spaced from the lip 12 of the cup and so arranged in angular relation thereto that these walls 14 may lie in close parallel relation when the cups are in lowered or open position, as shown in Figures 2 and 4. In order to accommodate the support 5| between the cups when so opened, the walls 14 are provided with a recessed or inwardly bowed portion 18 in each, and having an inner bight part receiving the upper reduced portion of the support 5| when the latter is lowered. The cam edge 19 of'the flange elements 65 is so shaped and positioned that when the plunger 52 is at its lowermost position and the cups 16 are engaged against the guard, as'

shown substantially in Figure 1, the lower part of the cup in the bight 80 of each cup will rest upon the outer, nearly or quite horizontal portion of the cam surface 79, and the cam surface is so shaped that as the plunger 52 is extended, moving with it the same work and pivot 11, the bight portion 80 will slide inwardly upon the cam, permitting the cups to move downwardly and inwardly by gravity, to the position shown in Figure 2. Upon downward movement of the frame and pivot again, the pressure of the bight portion 80 against the cam surface 19 will cause the cups to swing outwardly, the bight portion 80 riding upon the surface 19 until the cups are raised again to full closed position as shown in Figure 1, when the plunger reaches a lower position, as indicated in the same view.

The guard 10 being formed with longitudinal slots 8! throughout the curved extreme edge portion of the guard, when the device is in use, lather and shaved, whiskers passing between the blade edge and guard will enter the slots and accumulate in the cups 1!). When the razor parts are moved to open position as shown in Figure 2, the cup is lowered from the guard, so that it is made possible to readily wash out the accumulated lather. In this way, the spilling of lather upon the person of the user of the razor is guarded against, as well as the soiling of floors, rugs and other objects avoided.

It will be understood that the disclosure of the 4 invention herein made is purely exemplary, and

that various modifications in the construction,

arrangement and combination of parts as well as,

substitutions of materials, and mechanical equivalents may be made without departing from the spirit of the invention, as more particularly set forth in the claims, but, having now disclosed with great particularity the embodiment of my invention in its best form as thus far developed, what I claim. as new and novel is:
