RAZOR-STROP.

Specification of Letters Patent.

Patented Mar. 1, 1910.

Application filed. August 5 1909. Serial No. 511,814.

' strops, such as shown and described in the Letters Patent of the United States, No. 580,231, granted to me April 6, 1897.

\ The object of the present invention is to provide a new and lmproved razor strop,

more especially designed for accurately stropping thin razor blades, of the Gillette and other types, in a very simple and effective manner and without much exertion on the part of the operator. For the purpose mentioned the rocker of the razor strop is adapted to receive a removable blade holder having retaining means for. holding the razor blade in position.

A practical embodiment of the invention is represented in the accompanying draw ings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a longitudinal section of the razor strop;.Fig. 2 is a plan view of the same withthe leather strop omitted; Fig. 3'is a perspective view of the blade holder; and Fig. 4' is an enlarged sectional side elevation of the rocker, the blade holder in position on the rocker, and the razor blade in position in the holder.

A slide or casing A is adapted to be moved lengthwise on the stropB of leather or other suitable material, the strop passing between fixed members C and movable members D'arranged in pairs on the ends of the slide .or casing A. The fixed members 0 are in the form of round bars extending transversely across the top of the stro) B, and the movable members D are in the orm of fiat plates fulcrumed on transversely extending pivot pins E, held in the sides of the slide or casing A and projecting somewhat beyond the said sides, as indicated in Fig. 2, for a purpose hereinafter more fully explained. The free ends of the movable members D are pressed on at the under side by springs'F, held on the slide or casing A, so that the strop 13 is clamped between the fixed members 0 and the movable members 7 D, with a view to prevent a too rapid forward or backward movement of the slide on the strop B.

In the sides of the slide .or frame A is mounted to rock the transversely extending shaft G of a rocker or carrier G, and at 1 one end of the shaft G is secured a pinion H, in mesh with a rack 1, formed or secured on one side J of a shifting frame, having a second side J connected by a cross bar J' with the side J, said sides J and J of the shifting frame being provided with elongated slots J engaging the projecting ends of the pivot pins E previously referred to. The cross bar J is provided with a depending handle K, to be taken hold. of by the operator for moving the shifting frame forward and backward until the movement thereof is limited by the ends of the slots J 3 abutting against the pins E. a

The rocker or carrier G is provided with a clip G formed from a single piece of sheet metal bent around the shaft G and secured thereto by solder or other means.

The clip G is rovided with two spaced members G receiving between them a blade holder L, for carrying the razor blade N. The blade holder L is formed from a single piece of sheet metal, doubled up to form at the doubled-up end a handle L and to provide two spaced members L and L for receiving between them the razor blade N, as plainly indicated in the drawings.

The member L is provided with inwardly struck up lugs L registering with apertures L formed in the other member L it being understood that the razor blade N is provided withapertures adapted to engage the lugs L when inserted between the members L and L of the blade holder L. The members L and L are also provided at their outer faces with longitudinally extending ribs L, adapted to engage correspondingly shaped grooves G formed on the inner faces of the members G of the clip G of the rocker G.

In using the strop, the blade N is placed between the members L and L of the blade holder L at the time the said members are spread apart, and when the blade is in position in the holder L, then the operator laces the holder L with its two members L and L firmly pressed to ether, between the members G of the cli Lt, by inserting the holder L from that en of the rocker opposite the one having the pinion H, as will be readily understood by reference to Fig. 2.

' locked to the slide to permit the latter to l Now, by having the ribs L engaging the grooves G, it is evident that the blade holder L is always held in the same posi tion in the rocker and as the blade N is correctl'y held in the holder L, it 1s evident that the-outer cutting edge of the blade N stands at the proper angle relatively to the upper face of the strop 'B when the machine is used for stropping the blade N. When the blade holder L carrying the blade N is in position in the rocker G and one end of the strop B is hung up on 'a fixed support and the other end is taken hold of with one hand by the operator, then the latter takes holdwith his other hand of the handle K and moves the slide or casing A' lengthwise on the strop B, whereby the rocker G is caused to rock to bring the opposite sides ofthe cutting edge'of the blade N alternately into contact with the upper or strap in face of the strop B to strop the razor la e. After the razor blade N is stropped, the operator takes hold of the handle L of the blade holder L and pulls the same out of the cli G. The members L, L of the removed lade holder readily open by their own resiliency, to allow convenient removal of the razor blade N for use in the safety razor.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A razor strop, comprising a strop, a slide fitted to move lengthwise, on the strop, said slide having spring pressed means for increasin the resistance of the slide on the strop an provided with"pro ections on its sides, a blade carrier mounted to rock on the slide and having a inion at one end, and a shifting frame on t e slide, and having a rack meshing with the pinion on the blade carrier, said rojections of the slide, whereby the shifting rame can be first'moved independently of the slide to rock the blade carrier and then be moved along the strop.

2. A razor strop comprising a strop, a l

rame being provided with a handle and slots in its sides receiving the slide fitted to move lengthwise on the strop, said slide having fixed and yielding members at its end between which the strop passes, a blade carrier mounted to rock on the slide and having a pinion at one end,

anda frame fprovided with a rack engaging whicha strop is adapted to pass, and rovided with projections on its sides, a b ade carrier mounted to rock on the casing and having a pinion at one end, and a shifting frame having on its upper edge a rack engagin the pinion of the blade carrier and provi ed in its sides with slots receiving the rojections of the casing and with a han le on its under side.

plns, a rack on one of the said frame sides,

a handle on the connecting bar of the shifting frame a rocker mounted on the said slide, a pinion on the said rocker 111 mesh with the said rack, and a blade holder for removable engagement with the said rocker.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
