ARTHUR U. -HAYDEN, OF BROCKTON, MASSACHUSETTS.

RAZOR-STROPPER.

Specification of Letters Patent. Application filed September 26, 1910. Serial No. 583,826.

Patented Dec.

To all whom "it may concern:

Be it known that I, ARTHUR C. ITAYDEN, a citizenof the United States, residing at Brockton, in the county of Plymouth and State of Massachusetts, have invented a new and useful Razor-Stropper, of which the following is a specification.

This invention relates to grinding and polishing, and more especially to the strops and bones -used for sharpening safety razor blades; and the object of the same is to produce a small and convenient device by which almostany 'type of safety razor blade can be honed and stropped quickly.

. To this end the invention consists in the details of construction set forth below and shown in the drawings, wherein,

Figure 1 is a perspective view of the strop and hone complete. Fig. 2 is a plan view; and Fig. 3 is a longitudinal section on the line 33 of Fig. 2. Fig. 4 is an enlarged side elevation of one end of the device showing the carriage. Fig. 5 is a cross section on the line 5-5 of Fig. 4. Figs. 6 and 7 are diagrammatic illustrations showing different windings of the belt for a purpose to be described below; and Fig. 8 1sa'sectional detail of the blade holder in the carriage.

The frame of this device is substantially rectangular as will be seen in Fig. 2 and comprises'two end bars 1 connected near their extremities by side bars 2, the connection here shown being by means of ears 3 at the ends of the side bars bent over into notches 4 near the ends of the end bars. The latter have threaded eyes 5 at their centers for handles 6 of which one is shown although there may be two. The extremities of the end bars project beyond the side bars and carry tracks 9, here shown as round rodsextending through eyes 7 in said extremities and receiving nuts 8 whereby the tracks can be removed, although any other suitable form of attachment might be employed as long as the tracks stand parallel with andat a slight distance from the side bars of the frame.

Midway of the length of the frame bearings 10 rise rigidly from its side bars, and between them is pivoted a shaft 11 on which is fixed a pulley 12 near one end of the shaft. Inside the adjacent side bar 2 near its ends arejournaled pulleys 13, and over thalatter passes a flexible and in'some cases an elastic cable 14; which is given a 0011 around the pulley 12 and which is provided with hooks detachably receive a safety blade 17 of any- 15 at its extremities to detachably engage the of the ordinary constructions now on the,

market.

The carriage is by preference stamped from a single piece of sheet metal initially rectangular in general contour and with.

eyes 20 at its corners which are bent up into parallelism as shown, and those at each side of the carriage embrace and are adapted to slide upon one of the tracks 9 as will be clear. Thence the metal of the carriage passes inward beneath the side bar 2 as at. =1

21, is bent upward as at 22 inside but out of contact with said side bar, and is then bent inward as at 23 and extends across within the frame, being by preference made rather openas shown at 24 for the sake of' it lightness.

Secured upon a diagonal bar across the carriage is the strop 25, and it is to be understood that although I have shown this as fixed thereon it may be removably attached thereto so that a hone orvotherfl abrading surface could be substituted when desired. In any event provision Wlll be made to attach a new strop when necessary,

and no claim is laid to the means of attachment although I consider it important that it shall extend obliquely across the carriage. 26 is a handle depending from the carriage by which the latter. is manipulated, and like the handle 6 this may be removed so that the whole device can be reduced to small com- 1 the latter is 'used, and the proportions and details are unimportant.

In use, the parts are assembled as best seen in Fig. 1 and the cable is wound around the main pulley 12 as shown in thatview and in Fig. 6. The operator takes the handle Gin one hand and the handle 26 in the other, and moving the latter to the right the carriage draws the cable 14 around the left hand idle pulley 13 and turns the whey 12 in a direction to throw the blade ll over as shown by the arrow; so that as the carriage moves beneath the blade holder, the latter revolves and carries the blade with it and by the time the front end of the strop In one of the lower bars 21 of the All parts are'preferably of sheet. metal excepting the strop and the hone when r has passed under the blade holder the blade has been turned over to a position where it is thrown down upon the strop and held there as the cable slips around the main pulley 12. The forward movement of the carriage is continued until checked by the right hand idle pulley 13, where a re-.

common types of safety blades can be inserted therein from that which-is remote from the pulley l2, and after sharpenin the-blade it is drawn from place and.used 1n the ordinarymanner.

Fig. 7 shows diagrammatically 10w the end of the clamp 16 cable-can be given a reverse winding around ing Within the frame and the idle pulleys and with its themain pulley 12 which'of course will cause a reverse movement of the blade holder and the blade it carries. It is hardl neces sary to illustrate how a hone or a rading surface may be substituted for the strep 25, but. when this is done and it is desired to push the ed e of, the blade across'this, surface rather face such as the strop, it will be clear that the winding of the belt 14 as illustrated in Fig. 7 will cause the opposite movement of the blade holder and blade as the carriage is reciprocated. i

What is-claimed as new is 1. In a razor stropper, the combination with a frame having bearings rising from it and idle pulleys journaled 'within it near its ends; of a. shaft journaled in said bear-in s .and carrying a blade holder a carriage slidsupporting a strop, a cable attached to the carriage and extending thence in either direction. around center coiled around said shaft, and means for reciprocating the carriage relatively to the frame.

2. In a razor stropper, the combination with a frame comprising side bars and end bars and tracks carried by the end" bars par- -and a cable coiled t an to. draw it-across a soft surallel with and spaced from the side bars, bearings risin from the mid-length of the side bars, and idle pulleys mounted inside one side bar near its ends; of a shaft journaled in said bearings and carrying a blade holder, a pulley fast on the shaft in line with the idle pulleys, a carriage having eyes at its extremities sliding on said tracks and a body between them supporting a. strop, around and adapted to slip upon said pulley on the blade holder shaft and extending thence over said idle pulleys and connected with the carriage.

:3. In a razor stropper, the combination with a rectangular frame comprising end bars having eyes at their extremities and notches just inside the eyes, side bars having ears at their extremities engaging said notches, and tracks consisting of round rods standing parallel with the side bars and ex- 'tending through the eyes of the 'end bars,

and nuts on their ends, said end bars having eyes at their mid-length; of a handle adapted to engage either of the last-mentioned eyes,

,a carriage slidably mounted on said tracks and carrying a strop between said side bars,

and means for a handle on the carriage,

the strop with holding the blade against yielding pressure.

4. In a razor stroppenthe combination with a frame comprising side bars and end bilrs, bearings rising fromthe sidebars, and i e its ends; of ashaft journaled in said bean ings and carrying a blade holder, a pulley fast on .the shaft in line with the idle pulleys, a carriage sliding within the frame and supporting a, strop, a cable coiled around and ada ted to slip upon saidpulley on the blade ho der shaft and extending thence over said idle pulleys, and hooks'connecting its ends withthe carriage.

In testimony that I claim the fdregoing as y own, I have hereto afiixed my sin nature in the presence of two witnesses.
