invented certain new and useful Improvements in Razor-Strops, of which the fo1lowing is a specification.

My invention relates to an improved. razor strop, designed especially for use in connection with anysafety or straight razors,

' the primary object of the invention being the provision of a device thatmay be operated either manually or by mechanical power for 'stropping a razor to keep its edge e in good condition for performing its required functions.

The invention consists in certain novel combinations and arrangements of parts whereby the razor is movably held insuch position that it may be presented, alternately, in contact with two revolving members carrying stropping surfaces, so that the: two sides of the blade may be stropped uniformly,.as will be hereinafter more fully pointed out.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention con structed according to the best mode I have so far devised for the practical application of the principles of my invention.

Figure 1 is a plan view of the device complete. Fig. 2 is an enlarged sectional detail view of the bearing for the rotary members. Fig. 3 is a sectional view of Fig.1 on line 33. Fig. 4 is an enlarged detail View partly in section, showing the'action ofthe shifting device for oscillating the razor in order to present its sides successively to the revolving stropping members. Fig. 5 is a side view, parts in section, showing the oscillatable razor holder. Fig. 6 is an en larged sectional view on line 66 Fig. 5. Fig. 7 is a sectional view at line 77 Fig. 5.

In the preferred form of the invention as depicted in the drawings herewith I have illustrated the device as manually-operated, but it will be understood that other forms of power may be employed to operate the device and other forms or arrangements may be adopted for the mechanical parts. But to illustrate the device in convenient form I- have employed a supporting frame 1, preferably of rectangular shape, which'imay be of metal or wood, or other suitable material", and is of required dimensions. The two side bars of this frame are connected by a cross bar or plate 2 which is rigidly fastened, as by screws, to the side bars and this plate 2 is the supporting member for the'revoluble shaft or axle 3, which is journaled by means of the ball bearings, 4 to rotate or revolve in the bearings when power is applied to the shaft or axle 3. I

At 5 and 6 (Fig. 2) the shaft is formed with squared portions in order that the two hubs 7 and 8 may befiXed thereto to rotate with the shaft. These hubs are round disks that carry the revolving members and the hubs are revolved through the medium of the crank, 9 attached at one end of the shaft.

The revoluble stropping devices comprise two open center rings or round plates 10 11. fastened to the hubs 7 8 by means of the projecting lugs 12 and screws 13, the former integral with the hubs and the latter used to secure the lugs to the rings. The rings are located adjacent each other and revolve simultaneously in parallelism, and the inner or adjoining face of each of these rings is provided with a leather or other soft covering suitable for stropping the edges of a razor blade. These rings may be of wood or metal as desired, and where a fine finish is not desired for the edge to be sharpened, the leather face of the rings may be displaced and acoarser surface provided. In any event it will be seen that the two parallel revoluble members are supported in the cross J strop the edges of the blade. The razor blade and handle are retained in a casing 16, preferably of sheet metal and formed of proper shape to fit over the blade 14: at 1ts back, and also provided with wings 16 at one end, to clasp the handle 15 of the razor.

The casing 1s preferably of resilient metal so that it sides may clasp about the razor blade and the two wings 16 may clasp firmly about the razor handle, and thus hold the razor firmly in the casing. The casing is preferably formed with a rounded end or bearing 18 which is adapted to seat in a socket is slotted to permit movement of the bar 18 when the casing 16 is oscillated. The eye bolt holds the casingin place, but permits it to oscillate with the rounded bar 18 as its center of oscillation. The casing and razor may be held against oscillation by means of the latch 20 which is pivoted at 21 to a post 22 and has a resilient forked end 23 to fit over the rib 17 and wings 16' of the casing 16. In Fig. 1 the latch is unlocked and'the casing and razor may be oscillated, but in Fig. 5 the latch is locked, and thGI'EiZOI' and casing stand between and parallel with the twostropping disks so that the razor edges -cannot contact with the stropping disks. 30

The casing and razor are oscillated through the medium of a yoke 23 which is provided with a cross bar24 that is slidable through a sleeve 25, fixed transversely to the rib 17 of the casing. A second bar 26 extends transversely of the yoke, and this' arm or bar is connected through the spring 27 to the post 22 of the cross bar 2, as'indicated at 28. The yoke 23 is slotted at 29for the spring 27, and the free ends 30 of the yoke project beyond the crossbar 24 in position to encounter the contact members or shoes 30 or 30. By this contact the yoke is swung as indicated in Fig. '4: and the yoke is caused to oscillate on the rounded end 18 as a center. The spring 27 tends to hold the yoke at its extreme position so that the razor blade edge is held against one of the leather rotary strops. The yoke is struck alternately by the shoes 30* and 30 and the bar 24: is caused to slide through the sleeve 25, and it'will be apparent that when the point 28, the point of attachment of the spring to the bar 26, and the'center of oscillation arein alinement, the razor blade will stand in line with all three of them, but when the yoke encounters one of the shoes the points are'thrown out of alinement, and in Fig. 4 it will be seen that the spring is holding the razor blade against the stropping disk face 10. Thesetwo shoes or contact members 30 and 30 act alternately on the yoke.

The shoe 30 is carried at the end of an arm 31 which is pivoted at 32 in brackets fixed to the hub 8, and. the inner end33 of this arm travels in a cam groove 34 which is endless and passes around the wheel 35 rotatably fixed to the hub at 36. A forked arm 37 projects from the hub 8 and guides the movement of the arm 31.

The cam Wheel 35 is freely rotatable on its journal 36, and is provided with four radial arms or spokes 38' which are in position to encounter. the bent end 39 of a fixed bracket 40 attached at 41 to the frame 1. From this description it will be seen that as the disk 11 revolves it carrieswith it the cam wheel and pivoted arm 31. Now

when the spokes, or rather a spoke of the wheel encounters the bent end 39 of the. bracket 40, it will be seen that the cam wheel is rotated one quarter turn, and the cam groove causes the arm 31 to move on its pivot, so that the shoe 30" is in position to contact with the yoke 23 and move it on the rounded end 18 as its axis. The two shoes 30 and 30 are located diametrically opposite each other, and the shoe 30 has a duplicate mechanism as arm 31 pivoted at disks are revolved the razor blade has both its edges stropped during a single revolu: tion of the stropping disks, and the continued rotation of the-disks causes the razor blade to move or be oscillated, first to one side and thenthe other. that the blade is not located on a line radial with the center of revolution of the stropping disks, and because of this relationship of parts the motion of the stropping sur- It will be noted I face over the blade. is from the heel of the blade toward the toe and the action is to draw the blade in the same manner as that accomplished by hand. It will be seen that both edges or sides of the blade are uniformly and effectively stropped, as the blade is alternately shifted from side to side by the action of the brackets and cam Wheels. The leather stropping faces of the disks may readily be renewed by removing the stropping disks fromthe hubs, and re-- placing the worn surfaces with fresh ones.

What I claim is I 1. The combination with a pair of revoluble stropping disks, of a frame between the disks, a blade retaining easing oscillatably supported in the frame, a sleeve on the easing and .ayoke having a bar slidable in the sleeve, means for contacting with said yoke to present the blade edge to alternate disks, and a resilient connection between the yoke and-frame. p z I j 2. The combination with a razor stropping device of an oscillatably supported blade-retaining holder having a sleeve, a transversely arranged yoke having a bar slidable in the sleeve, a supporting frame, and a spring having its ends attached to the frame and yoke whereby the spring is adapted to hold the parts out of alinement.

3. The combination with a rotary stropping device, of a blade retaining casing 0s- 'cillatably supported and its frame, a movable member co-acting with said casing, and a resilient connection between said member and frame adapted to oscillate the casing when its points of connection are out of alinement with the axis of the casing.

4. The combination with a pair of rotatable stropping disks and an oscillatable blade retaining casing, of a revoluble cam wheel carried by each disk, means for revolving each wheel, and a cam arm actuated by each wheel adapted to operate said oasmg.

In testimony whereof Iafiix my signature.
