Frederick Kampfe, of New York, N. Y. Razor-Strop.
No. 812,568. Specification of Letters Patent. Patented Feb. 13, 1906.
Application filed August 14, 1905. Serial No. 274,027

To all whom it may concern:

Be it known that I, Frederick Kampfe, a citizen of the United States, residing in the borough of Brooklyn, in the county of Kings, city and State of New York, have invented an Improvement in Razor-Strops, of which the following is a specification.

My invention relates to devices for suspending a razor-strop from a hook, and the same relates particularly to a strop having but one side or member, which does not require to be turned over for use during the operation of stropping the razor, with the object of employing a simple, strong, and durable suspending device of inexpensive character.

In carrying out my invention I employ a strong braided cord, a tube of metal correspondingly notched at opposite ends and longitudinally split, and a clip, the free ends of the cord being received in the tube, which is pressed firmly about the cord to grip the same. The cord passes through the notched ends of the tube and is gathered together and held by the clip. The leather of the strop is notched in the edges at opposite places near one end and passed around the tube, with the parts of the cord in the notches which are adjacent to the notches of the tube, and eyelets are employed to connect the bent-over end of the strop with the main portion. An eye is thus formed at the end of the cord for suspending the strop.

In the drawings, Figure 1 is a broken elevation representing the devices of my improvement. Fig. 2 is an edge view of the same, and Fig. 3 is an elevation representing the cord and the split in the tube alone.

The cord a is preferably of strong substantial character and is advantageously ornamental in appearance for the use to which it is put. It may be of any desired length.

b represents a long split tube with end notches 2 3, which notches are of a width almost equal to the diameter of the tube. The respective ends of the cord are passed into the split tube until they meet at approximately the center of the tube. The tube is then pressed firmly about the cord, so as to grip the same, and the cord passed through the notches at the ends. In length this split tube should substantially agree with the width of the strop, which, as illustrated in the present case, is formed of the leather piece d of any suitable length, the edges of which at opposite places and at one end are notched to receive the cord, said end being passed around the tube, so that the notches of the leather are adjacent to the notches of the tube, and e represents eyelets by means of which the leather of the strop is securely fastened around the split tube.

I have shown and prefer to employ a clip c, of metal, which surrounds the parts of the cord a, which are gathered together. This forms of the cord at one end a loop to be passed over a hook to suspend the strop and to hold the strop in use, and it draws together the parts of the cord between the clip and the end of the strop, so as to hold the cord securely in the notches and prevent any slipping or the separation of the cord from its place of support. As there is no necessity in this form of strop for turning the same over and the employment of a swivel therefor, the cord and its means of connection to the leather of the strop form a very simple, convenient, and inexpensive structure.

I claim as my invention—

1. In a razor-strop, the combination with the leather portion of the strop having opposite edge notches near one end, of a longitudinally-split tube having end notches, a cord, the free ends of which are passed into and securely held by said split tube, with the parts of the cord passing through the end notches and also through the notches formed in the edges of the leather of the strop at opposite places, said tube passing through the turned-over end of the strop and means for securing the said turned-over end to the main body of the strop.

2. In a razor-strop, the combination with the leather portion of the strop having opposite edge notches near one end, of a longitudinally-split tube in width agreeing with the leather portion and having end notches at the opposite side to the split or division, a cord, the free ends of which are passed into and securely held by said split tube, the parts of the cord passing through the end notches of the tube and also through the notches formed in the edges of the leather of the strop, said tube passing through the turned-over end of the strop, and a clip passing around and drawing together the parts of the cord slightly beyond the strop so as to form a closed loop at one end.

Signed by me this 10th day of August, 1905.

Frederick Kampfe.
