Y., A CORPORATION OF NEW YORK RAZOR-BLADE STROPPER Application led September 24, 1925. Serial No. 58,371.

This invention relates to improvements in holders for razor blades for use during stropping of the blade. y

One of the objects of the present invention is to provide a simple and cheaply conf structed holder of this type. Another object is yto provide a guard for the blade which is rigidly fastened to the holder proper, and which is resiliently capable of yielding during the stropping operation to permit the edge of the blade to be presented to the strop at the proper angle under the pressure employed during stropping, and which upon the cessation of such pressure is automatically and immediately returned to they original position. Another object is to provide a. holder of this type which has few parts and in which these parts are secured together in a permanent manner so that parts thereof cannot be misplaced or lost. A further object is to provide ablade holder of this type in which the blade is easily and quickly inserted and secured within the holder, and the device as a whole may be operated by an unskilled or careless person `without danger to the flesh or the strop.

With these and other objects in view, there are shown on the accompanyingr drawings several forms of the invention, in which:

line 10-7-1() of Fig.

In Fig. 1, the blade holder is shown as having the two handle sections 10 and 11 which are pivoted together at one end by a hollow rivet 12. In form, each of these handle sections has at the pivot end an aperture to ren celve the pivoting rivet 12, and adjacent thereto a transverse ridge 13 of greater length than the normal width of the handle section and projecting at each side: which is cut away at 14 on the portions of these handle sections facing each other, as will be more fully described hereinafter. The handle sections then have slightly arched portions 10, 11a of normal Width adapted to receive and clamp a razor blade B between them followed by a second transverse ridge 15 of substantially the samelength as that at 13 and likewise projecting to each side, and cut yappropriate thickness to enable the user to obtain a good grip upon the device.

- These handle sections, in Fig. 1, are held n together and upon the razor blade B by a cup 19 which is adapt-ed in size to fit tightly over the two hollow sections 10 and 11 at the end removed from the pivot point. This cup 19 is carried by a slider 2O which isr fastened securely to the handle section 11 by a rivet 21 with a large head, which passes through a slot 22 in the slider. The slider may be moved back and forth upon this rivet, and is guided in invariable lateral relation to the handle sections by the projecting sides of the handle section 11.

The guard for the edges of the razor blade consists of the two longitudinal elements 23, 24, which are gashed or slit at their'ends to receive thin sheets 25, 26 of spring metal such as brass, and united therewith by soldering or the like to produce a rigid connection. These sheets 25, 26 are each made T-shaped in plan, andare secured at the stem of the T `to the handle section 11,'as shown in Figs. 2 and 3, by passing the stem of sheet 25 beneath the handle sections 10 and 11 in assembling the device, and by employing the rivet 27 for the sheet 26. Since the sheets 25, 26

are connected together by the elements 23, 24, and the rivets 12 and 2T are drawn tight, the guard assembly is held rigidly and substantially immovably at its central section in the handle section 11. The razor blade B is received between the sheets 25, 26 as indi-y cated iu'lligs. 2 and 3. rlhe transverse bars of the T-shaped sheets are held therefore in rigid alinement witlrand between the transverse ridges 13 and 15 of the handle sections 10 and 11, but by the resiliency of their material are Apermitted to roclr under the'lpressu're of stropping into a positionsuch as shown in dotted lines in Fig. t, in which the element 23 or 2e which has been rocked uncovers the edge of the blade and permits the latter to present itself to the strop at the proper angle.

The blade?) is received between 'the two sheets 25, 25, as shown in Figs. 2 and 3, and is preferably `held against displacement either longitudinally or transversely of the handle sections bythe/lugs 30 which are made solid with the portion 11'd of the handle section 11, and pass through the usual aperture-s in the central line of the double-edge type of blade, and thereby secure the blade against displace ment. A

In operation, with the blade .holder in the open position as shown in Fig. 2, a razor blade B is placed loosely in the holder, with the Vlu gs 30 passing"through its apertures. rlhe handle section 10 is then rotated about the pivot 12 until it Vliesl parallel to and against the handle section 11. The cup19 is then pushed inward to 'bind the two .handle sections together. The handle sect-ions are preferably formed so that they spring apart slightly, and this resiliency is employed to hold the cup 19 in place upon them.

The holder and blade are then ready 'for use. The user grips the holder and strop and rotates the ,holder 'slightly and pushes one ofthe guard elements downward against the strop while holding the holder in a sonrewhat oblique position, at the same time moving the holder along Vthe strop inthe custom? ary manner. The guard element rocks away by reason of the re. iliency of thesheets 25, 25 and permits the edge 'ofthe blade to be presented to the strop at the predetermined and pr per angle established by the angle of the cut- away portions 14, 16.

Then the stropping 'is completed, the cup 19 is pulled out, the handle sections 10 and 11 spring apart, andthe handle vsection 10 may be rotated about the pivot 12 to the position shown inFig. 2, and the blade lies free yfor removal. Y

ln the modified form shown in Fig. '6. 'the holder' is adapte-d for a single edge blade having a thickened back. rlhe construction in general is the sameas with the previous form except that the ridges 1an, 16a project at one side only. T he thickened baclrof the blade is received and clamped by the slightly arched construction shape of the handle sections 40 and 41 which resemble the handle sections 10la and 11n, to prevent transverse movement vof the blade in the holder, except that the lugs 42 are provided at the ends of the position of the blade to prevent the blade from moving longitudinally of the holder. Pivot i3 connects the handle sections 40, 41. The operation is the sameas before. Y

In the modilied form shown in Figs. 7 and 8, the two handle sections and 51 are connected by a. transverse pivot, formed by curling the y'end 52 of section 50 and passing it through an aperture 52a of section. 51. The arrangement of the ridges '1l-b, 161 and of the guard is the same as before except that an individual rivet 27b is alsoprovided for the sheet 55 as well as the rivet 27, sheet 56. The handle sections 50, 51 in this case are held together by a slider 5l which is mounted for movement relative to the handle `section 51 by a rivet 53 which passesl through a slot 57 in the handle section 51 and has an en larged head 58 which holds the slider in fixed Ysliding relation with the section 51: lthe upwardly curled side portions of the handle section 51 guide theslider 541- in its-movement. A further lug 59 with an enlarged head 60 is adapted to pass through theenlarged end 61 o f a slot 62 formed in the handle section 50 and thereafter to beforced with the slider 54 into the narrower end of this slot, to hold the handle sections tightly together: the two members 58 and 6() are easily accessible for the lingers of the user, and enable him to manipulate the device with great facility.

A'lhe construction and operation are otherwise the sameV as with'thefforrn of Fig. 1.

In the modified form of Figs. 9 'and 10, the portions of the handle-sections for clamping the blade, and theguard are the same as with Figs. and 8; but the securing arrangement Yfor the handle sections and 71 comprises a sleeve 7 2 which slides over the two handle sections. The section 71 is much longer than the section 70, and is reben't at its end, so that the rebent portion 71- lies parallel to the Voutwardly extending portion and forms therewith a hollowV tube, which extends inward to the end of the handle section 70. The

portion 71?1 has a longitudinal slot 73 therein, to receive a lug 74 lined in the sleeve 72, as shown vin F ig. 11: the length of this slot is suflicient to permit the sleeve 72 to 'be withdrawnl from over the handlesectio'n 70, which may then be swung upwardly and away about its pivot as shown by theiarrow 76. The operation and construction are otherwise the same as before. i y

It will be noted that in all of these devices, the handle sections,- guard, and handle sec tionsecuring means are rigidly and permanently fastened together. ln all of them the guard is rigidly fastened at its central longithe razor blade held in said devices, said tudinal line to one of the handle sections, but member being limited in its movements by it is permitted to yield resiliently by the mansaid stops.

ner of its mounting; and is limited in this movement at each end of the razor blade by the cut-away portions of the transverse ridges.

Other modiications may be made in the form and arrangement of the parts within the scope of the appended claims.
