Application filed Au ust 20.1907. Serial No. 389,329.

To all whom it may concern:

Be it known that l, ALEXANDER CRAIG, a subject of Great Britain, residing at 48 Mos ton Lane, Blackley, Manchester, in the county of Lancaster, England, hair-dresser, have invented new and useful improvements in Razor strops or Devices for Stropping Razors or Blades, of which the following is a specification.

- My said invention relates to a razor strop for stropping resorts on a new system involvthe use of an endless band or strop, of any suitable material, which is carried by or contained within a compact contrivance. The band or strop is so supported or carried that it can be frictionally or otherwise rotated to eilectthe stro ing, and the design is such that the razor blade can be quickly inserted in position for stropping and' ust as readily removed, while the device cannot be actuated to have harmful effect on a razor edge but only used advantageously. 1 pro l r or sheath. or device to receive 1 the razor blade or back while 11 use the edge is being acted o oy the endless band, and such holder sheath may be a detachable contrivance. i he endless band or rotatable strop is sup-- rented on one or more small drums or spins, or on a drum and spindle, and is tenrotatable spindles or parts suitably sustained may guide, deflect, or tension the endless or e stable strop. Adjustable or other stro s o buii'ers may be fitted to limit the nting movement of the blade when inserted, sothat the edge cannot sufier by coming into contact with the frame when the strep is in use.

I will now describe in detail and with the aid of the attached drawing a form of stroppingdevice in accordance with my invention. On the said drawings :Figure 1 shows a side elevation of the stropper. Fig. 2 is a front end elevation. vation. Fig. 4 is a section. Fig. 5 shows in plan view a form of spring support for the top roller or spindle. Fig; 6 is a diagram indicating the more or less essential elements of the stropper, and shows a razor blade in position in the sheath. Figs. 7, 8 and 9 are respectively end, side, and plan views of the holder or sheath. Figs. 10' and 11 are sooional diagrams indicating that (when the otropper is actuated) the blade is automaticned any convenient we. and additional Fig. 3 is a rear end ole- I ally canted to bring the edge against the ascending length of the band. FigsflZ and 13 show a form of sheath or holder to receive and hold a *illette or other thin blade to enable such blade to be sharpened in the new stropper. Fig. 14 illustrates the application of an enveloping holder to hold the sleeve and yet permit the stropper device to move or vibrate to the supported blade. Fig. 15 indicates a carrier or support with thin safety blade.

In the form of razor strep shown, I use a small or compact casing or frame A preferably a metallic casing having two sides a a with turned-in edges and a top (1 which casing can be readily bent or fashioned from sheet metal. The casing of whatever material is designed to slip on the blade, that is,

end. Towards the base of the frame a small drum or roller 1) is located and journaled in the frame ends or otherwise supported so as tobe capable of revolving. Towards the top of the casing, and in the example shown shrouded thereby, a spindle or roller cis arranged, and between the drum 5 and spindle c the endless band or strop cl runs, and other smail sta-ys 0r rollers such as e 6 may serve as additional guides or deflecting means.

The strep (i may be or" leather or other suit able substance or material and the required tension may be obtained in any convenient manner. in the stropper shown steel Wires or springs f gsupport the drum or roller l1 and the small roils e, e. The spring f has its lower bent end f turned into a small metallic bearing in roller 5 While the upper horizontal length passes throu h c and has its end riveted-up in one of t e check-pieces or sto s a projecting from the metallic sides a. T e extremity g of the spring 9 likewise engages or fits in a bearing in the opposite end of roller 5 while its upper horizontal length passes through the other roll c and has its extremi riveted-up in another check-piece a at the opposite end of the casing 11, as the drawing clearly shows. It is thus obvious that the springs f 9 form axles upon which rollers l) and c e rotate.

The top a of the casing or frame is fashioned to form or receive a resilient support for the small roll 0 and in the drawing this support takes the form of a fiat steel spring with turned-down extremities bored to receive the reduced extremities of the roll 0.

to give access to the razor b ade irom one v The steel spring is firmly held and the re quired amount of flexibility secured by passing the spring below, above, and again below, the wall (L as Figs. 1 and 5 indicate.

The holder or sheath for receiving and supporting the razor B. may well consist of a split sleeve or sheath i and may be made detachable and have notches or projections to engage the frame, or other interlocking nieans to lock or hold the sleeve firtmly in position. In the drawing, projections i are formed on the sleeve and when the sleeve is in position such projections abut against and engage the choc -pieces or stops a The middle portion of the sheath i is bent-in or curved on either side and the split is expanded when the razor is thrust in. Whether the sleeve or sheath is fixed or detachable it is so disposed that when the razor is inserted therein the razor lies between the inner faces of the, endless band d in an approximately mid-position. With the razor in position, and the handle thereof serving as a handle for the Whole device the drum b with support ed band is rubbed on the hand, the knee, or a table, or other smooth surface, and, when this occurs, the casing is naturally canted against the blade and the band is ro 1 tatedso as to rub against the edge of the blade and travel in a forward direction upwards. from the edge. This is an important point, it being a peculiarity of the construction, that, to effect rotation of the band, the

device is automatically canted into such a position that the edge of the razor lies against the face of the band which is ascending. Rubbing the device from right to left brings alternate sides under the influence of the strop in regular sequence, but, whichever way the razor lies, the band is ascending when stropping. takes place. This important characteristic of the stropper I seek to illustrate by the two sectional diagrams Figs. '10 and; 11.

I may design the sleeve or holder that the razor shall enter from one side in preference, and in the drawing the razor is intended to be inserted at the right-hand side Fig. 1.

I may construct the sleeve or holder so that if the razor blade is introduced at the wrong end the sleeve will ultimately bind on the blade and prevent same being pushed too far. i

The chock-pieces or stops a serve the ad.

ditional purpose of preventing the razor blade being pressed too far sidewise obviating any risk of damage to the edge by concan be removed and a new one introduced.

\ To enable my contrivance to be used for sharpening the thin blades of safety razors,

erases I may provide and sell with the stropper a hafted or handled clamp such as 1' made of sheet metal, split from 7' to 9' such clamp being. punched to produce holes and snia flanges at 9' j to fit the usual holes in the thin blade 9' when the halves are pressed together. The base of the clamp is shaped at to fit the sleeve or sheath i in the stropper,

the pushing of the clamp into the sleeve or sheath i keeping the halves together so that the device 7' serves to take and hold the thin' safety blade While being stro ped.

As a modification I may t the stropper device with a holder or casing C which on.- velops and contains the stropper save the friction drum 6 such holder engaging by fangs Z and encircling portions 1 a sleeve '5 and rigidly housing same. The construction is such that the stropper casing can vibrate in the holder or casing C with result that the traveling band (1 is brought against a razor blade when held in an u right position the sleeve '5. The thin bla esuch as j isiinmrted in a clamp or carrier such as (Fig. l5)

and this clam is usedto hold tblade. in the sleeve 71. the sleeve 'i inc more or less vertical position its edge is. brought under the action of the band d as it rotates and as the stroppnrdd vice is vibrated from side to side.
