RAZOR-STIRO?.

Specication of Letters Patent.

Patented J' an. 26, 1909.

Application filed September 30, 1908. Serial No. 455,411.

To all whom it may concern:

Be it known that I, ELIJAH E. DEPUTY, a citizen of the United States, residing at Parkesburg, in the county of Chester and State of Pennsylvania, have invented a new and useful Razor-Strop, of which the followingris a specification.

his invention relates to razor strops.

The object of the invention is to rovide a novel form of strop adapted mec anically, and with rapidity and accuracy to strop razor blades of'any character. Furthermore, in a novel manner to prevent injury to the strap, as from nicks or cuts.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists, generally stated, in a razor strop comprising a self-winding roller, a strap wound thereon, an oscillatory blade holder embodying a pinion, a gear carried by the roller and rotatable independent thereof, but being at the proper moment caused to rotate with the roller, and a blade holder reversing-gear that meshes with the pinion and with the roller gear, and being operated by the last named gear when the strap is unwound from and wound upon the roller, the reversing of the roller taking place at the instant that the direction of the motion of the strap is changed, thus to prevent nicking or cutting oi' the strap.

The invention consists further in the various novel details of construction of a razor strop, as will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification, and in which like characters of reference indicate corresponding parts :-Figure 1 is a view in erspective of a strop constructed in accor ance with the present invention. Fig. 2 is a vertical longitudinal sectional view through the strop. Fig. 3 is a transverse sectional view taken on the line 3 3, Fig. 2, and looking in the direction of the arrow thereon. Fig. 4 is a fragmentary sectional view taken on the line 4-4 he strop com rises a casing, preferably of metal, and whic may be ornamented if desired to impart a neat and finished appearance to the article. The casing comprises side walls 1 and 2, end Walls 3 and 4, and a top wall 5.

Arranged within the casing is a self-winding roller embodying a tubular shell or body 6, one end of which 1s closed b a ca 7, and the other end by a head 8 whic is he d in position by a plurality of screws 9.

Arranged within the shell 6 is a shaft 10, one end 11 of which is squared and projects through the cap 7 and engages a square o )ening in the side wall 2, that portion of the s aft that projects through the cap being circular to provide a bearing. The other end of the shaft is reduced to rovide a circular journal 12 which works in tlie bearing 13 that projects through the head 8. Surrounding the shaft is a coiled spring 14, one end 15 of which projects through a transverse opening in the bearing 13, and the other end 16 through a transverse opening in the shaft adjacent to the squared terminal 11. The shell is supported for rotation at the end carryin the head 8 by a screw 17, the head of whic 1 is journaled 1n the side wall 1, and the threaded shank of which engages a threaded opening in the head. From this arrangement it will be seen that the shell will be supported for rotary movement in either direction, and further, that the shaft will be held positively against turning so that when the strap 18 is drawn away from the casing, the spring 14 will be wound up or placed under tension, thus to store up energy to secure the automatic rewinding of the strap. The strap 1S may be secured to the shell 6 in any preferred manner, the connection between the parts, in this instance, being effected by stamping out a lurality of curved tongues 19 from the shel and passing these through suitable openings provided in the strap for the purpose. The screw 17 adjacent to its end 1s clrcumferentially reduced to provide a journal 20 for a gear 21, which latter, as will be obvious, is free to rotate independently of the roller. In order, at certain times in the o eration of the strop, to cause the gear and t e roller to rotate together, there is a frictionally acting restraining device employed, which consists of a s ring 22 somewhat less in length then the dlameter of the gear 21, and which is mounted upon the threaded portion of the screw 17 and is clamped against the head by the inner face of the journal 20. The spring, on each side of the screw is inwardly bowed to provide two contact faces 23 that are designed to bear against the head S, and outwardly bowed at the point where the screw passes through it, to'provide acontact face 24 which bears against the inner- Fig. 4, the shaft being provided with a head 27 to hold the gear against Working oil, and with a threaded extension 28 that carries a nut 29 for clampin the shaft in place. The gear 25 meshes Wit a pinion 30 that is preferably integral with a tubular shaft 31 to which is secured, in any preferred manner, a razor blade carrier 32. The shaft rotates upon a bearing 33 in the nature of a bai-'or rod, one end of which is passed through an u -standing ear 34 carried by the up er edge ci) the side wall 2 and is rovided Wit a head 35, and the other en of which projects through an opening in the side wall 1 and is threaded to receive a nut 36, b i which the bearing is held in lace. On eac side of the ear 34, the meta of the side Wall 2 is cut away, as clearly shown in Fig. f1, in order to allow the holder to accommodate the blade of an ordinary razor, and'to permit the shank thereof to move through the are of the circle to bring the blade B into contact with the stra The bearing 33 is so positioned relative y to the up er edge of the side Wall 2, as to throw the b ade holder a sufficient distance upward beyond the same, to permit the ready insertion of the blade of a razor oi' any kind, either hand or safety. As will be obvious, there will be a tendency for the strap to sag, owing to the pressure of the razor between the two gears 21 and 25 and to prevent this, there is a roller 37 provided which is mounted upon a rod 38, the terminals of which are secured in any preferred manner in the side walls 1 and 2. This roller will freely rotate as the trap is actuated, and Will secure the object sought in a practical manner.

ln order to prevent the strap from sagging between the gear 25 and the end Wall 4, the latter is provided with a longitudinal slot 39 through which the strap projects, as clearl shown in Fig. 1. The strap is furnished Wit an ordinary hand grip or loop 40 by-Which to exert a draft or pull on the strap. In order to support the casing in operative position, the rear wall is provided with tivo openended slots 41 that are designed toengage with nails 1T (one of which is shown in Fig'. 2) driven in a wall or other object. B having the slots 41 open-ended, asv described, the casing may readily be placed iripositie'ri and removed as required.

lin-'the use of the apparatus, Whenthesame is inthe position shown in Fig. 2, the razor blade is inserted in the holder 32. The loop 40 is now grasped and the strap drawn outward. The iirst motion of the strap will cause the gear 21 to rotate the gear 25, and the latter to rotate the shaft 81, thereby reversing the position of the razor blade, so as to cause its cutting edge to be projected in the direction of the movement of the strap, the same procedure taking place when the strap starts on its return movement to be re- Wound upon the roller. As soon as the blade is reversed to bring the razor blade in contact With the strap, the friction device 23 will permit the gear 21 to remain stationar until the return movement of the belt egins, whereupon the friction device Will again become operative to cause the gear 21 to torn and thus actuate the gear 25 and pinion 30 to reverse the blade holder.

All of the parts of the apparatus are se cene structed and arranged as to insure accurate Work and to be durable in use.
