SHAVING DEVICE Filed Jan. 28, 1951 2 Sheets-Sheet 1 INVENTO Patented Apr. 10, 1934 UNITED STATES PATENT OFFICE 5 Claims.

My invention relates to shaving devices commonly known as razors of the hoe type coupled with devices for sharpening the edges of the blades thereof; and has for its objects, first, the construction of a razor wherein the blade may be easily moved from shaving position to a position whereby it may be inserted into the stropping mechanism without removal from the frame; second, means whereby the razor frame and blade may be inserted in the sharpening mechanism and held therein in operative position; third, means whereby the blade may be honed or stropped without withdrawal from the razor frame and honed or stropped in the sharpening mechanism either progressively or selectively; fourth, means whereby the blade may be inserted into the stropping mechanism only when the sharpening elements are in inoperative position; and fifth, means for cleaning the blade before insertion into the stropping mechanism. Other objects will appear hereinafter.

I attain these objectsby means of the devices and mechanism illustrated in the accompanying drawings, in which- Fig. 1 is a side elevational view of the razor with the blade open or in position to enter the sharpening mechanism; Fig. 2, a plan view of the razor with the blade in the closed orshaving position; Fig. 3, an elevational view of the back of the razor as in Fig. 2; Fig. 4, a side elevational view of the same; Fig. 5, an enlarged plan View of the under side of the blade holder; Fig. 6, a section on line 66 Fig. 5; Fig. 7, a fractional side elevational view of the right end of the blade holder; Fig. 8,an enlarged end view of the blade holder; Fig. 9, an assembled side elevational view of the stropping mechanism with the right portion of the case broken away and shown in section on line 99 Fig. 10 and with the blade holder of the razor shown in sharpening position on the lefthand portion; Fig. 10, an end elevational view of same; Fig. 11, a section on line l1-11 Fig. 9; Fig. 12, a section on line 1212 Fig. 9.

The razor is of the hoe type having a handle 1 a frame 2 with elevated supports 3 and a rake guard 4. Into supports 3 are journaled pintles 5 on the blade holder 6 which thus enables the blade holder and blade 7 to swing in the direction of the arrow from the shaving position resting on the rake 4 (Fig. 4) to the open or sharpening position (Fig. 1). In this latter position the holder and blade are constructed so as to enable them to enter thecase oi the sharpener and gain support in operative position upon and between the guide rails 32 therein provided. I have found that in blade edge will contact with the rounded surfaces of the sharpening rolls 25. Ihis correct position, being somewhat critical, makes it necessary for the blade holder 6 to resisttwisting movement as well as vertical displacement. The weight of the handle 1 extending upward tends to cause it to wobble or twist, the motion of the rollers tends to draw the blade downward, and sidewise movement of the handle tends to dislodge the blade from the correct alinement with the rolls. To provide this necessary rigidity the blade holder is made with two guide ribs 8, which extend laterally along both sides of the lower lips of theholder 6, projecting outward therefrom and forming flange-like ribs. When the rollers in the stroppingmechanism are 'set at open position, as hereinafter described, the blade holder, in open position, may be inserted between the guide rails 32 and the guide ribs slid into grooves 37 in said rails, forming the necessary rigid support. The

blade herein illustrated is of the single edged backed type, and is adapted to slide into the holder in the grooved slot 9, in the holder, inthe direction of the arrow, (Fig. 5), until it is stopped at the left hand end by the termination of the grooved slot. It is then fastened in position by the swinging latch 10. See Figs. '7 and 8.

In Fig. 8 the latch 10 is shown in closed position, while the open position isindicated by 10' in dotted outline.

Near the ends of the blade holder I provide earns 11 which are shaped as shown. particularly in Fig. 6. Spring 12 is somewhat crescent shaped, fastened to the frame 2 in the center and provided with fiat contact faces 13 at the ends which bear upon earns 11 thus maintaining the blade in either of the two positions, shaving or sharpening. In order to facilitate movement of the blade and holder to the open position I provide lever 14 which may be actuated by a downward movement of the thumb while the handle 1 is held by the fingers of the user.

The sharpener comprises a base 15 upon which is fastened a U shaped support 16. Intothe upright ends of this support shafts 1'7 and 18 are journaled. Shaft 1'7 extends outside the case 19 at the right hand end as shown in Fig. 9, and to this extended end the knurled adjusting wheel 20 and the unidirectional crank 21 are pressed on or otherwise attached and keyed in place. This crank is designed to permit the turning of the shaft 1'7 in a counter-clockwise direction only when viewed as in Fig. 10. A spur gear 22 on shaft 17 positioned close to the right end of support 16 operates thru the intermediate gears 23,

5 to drive gear 24 and turn shaft 18 on which it is tion for sharpening.

fixed in the reverse direction. Mounted upon said shafts and turning therewith are segmental rolls and 26. These are composed of a metallic frame with a longitudinal back 27 having upturned ends 28 forming supports. The backs 27 have a semi-circular contour and form support and backing for the sharpening material 29 which is stretched over them as shown in section in Fig. 12, and held in place by the bars 30 and screws 31. This material may be of leather or other suit able honing or stropping substance. These rolls are preferably made at least twice the length of the blade to be sharpened thereby permitting two strips of stropping or honing material to be fastened to each roll side by side. The strips on the right (Fig. 9) may then, for example, be coated with suitable abrasive material, and thus adapted to honing, while the other strips may be treated and adapted to stropping purposes. Two of the leather strips may be supplanted by a similarly shaped grinding surface.

The guide bars 32 are made of metal having a somewhat elastic quality so they may be slightly sprung together to assist in holding the razor blade holder 6 in sharpening position. They have a flat upper portion which comprises the guide proper, and downwardly extending legs 33 fastened at both ends to the support 16 by means of screws 34. These screws engage the ends of 16 thru the elongated opening 35 thus providing vertical adjustment of the guides relative to the line of contact of the sharpening rolls on the blade edge. The two guides are held in position together by screws 36. Grooves 3'7 are channeled out along the opposite faces of the guides and these are further shaped in cross section to accommodate blade-holder 6 which is thus enabled to slide along the entire length of the guides and of the sharpening rolls, the blade '7 being at all times in correct and operative posi- The ends of this grooved portion are somewhat enlarged at each end, as shown at 37', to permit ease of entry of the blade holder.

To prevent cutting the rolls when the blade is inserted I provide a gate, composed of a disc 38, fastened on shaft 17, having two arcurate portions cut away 39 to permit the blade and holder to enter the guides only when both rollers are in inoperative position. Thus in Fig. 11 the gate is shown in closed position while the open position which would be approximately 90 degrees from the position shown, is indicated by the dotted outline 39'.

Fastened into slots in the ends of the case 19 are scrapers 40 made of soft rubber. These are bifurcated, as shown in Fig. 10. As the blade is slid into sharpening position these scrapers remove any soap lather or other objectionable substance from the blade.

It is to be understood that gates and scrapers are provided at both ends of the structure, and that the blade and holder may be inserted and/ or removed from either end. Thus the portions of the rolls adapted for honing or stropping may be selected, or the blade moved from one portion to another without removal from the case of the sharpener or the guides.

The entire structure of the sharpener is enclosed in case 19, fastened to the base by screws,

and may be equipped with hemi-spherical rubber feet 4.1 or other suitable support.

The operation of this device is extremely simple. To shave a blade is inserted in holder 6 and locked in place by latch 10. The blade may then be moved down to and resting upon the guard rake 4, and the razor used for shaving. When, during this process, or otherwise, it is desired to sharpen the blade it is moved to the open position as shown in Fig. 1 and inserted into either end of the sharpener case 19 thru the slot provided in scrapers 40. The hand wheel 20 is then turned backward or forward until the gate assumes an open position. The blade and holder will then enter the space between guides 32. The razor may be slid to the desired position as the rolls and sharpening effected by turning crank 21 as above mentioned. After sharpening, the razor may be removed by sliding it out of the guides at either end of the case.
