SPECIFICATION forming part of Letters Patent No. 272,042, dated February 13,1883,

` l Applicationtilcd December19,1882. (No model.)

o all whom it may concern:

Be it known that I, EDWARD P. HAFF, of the city of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvementin Razor-Strops, of which y the following is a specification.

The invention relates to that class of razorstrops which are formed on afour-sided block ot'` wood or other material. On one side of this block is attached a hone, on two other sides tablets or elastic surfaces, and over the fourth side is arranged a strap provided with means for tightening it.

The invention consists in a device whereby the strap is secured to the block at one end and tightened more or less, as desired. Y In the accompanying drawings, Figure 1 shows the strop with the tightening device in longitudinal section. Fig. 2 is a transverse section on line w .e ot' Fig. l, and Fig. 8 is a transvei se section on line y y ot' Fig. l.

Similar letters ot' reference indicate like parts. i

'A is the four-sided bodyof the strop, which may be` of wood or other suitable material. The side B, for example, may have attached `to it a hone,and the sides G and D may carry tablets or elastic surfaces. To the end ot' the block A is secured, by cement or other suitable means, the strap E. Said strap passes over a projection, F, and its end is attached 'i by rivets to a metal` plate, H. Formed upon or rigidly attached to said plate H, and at right angles thereto, are two plates, I and J, which enter recesses G, formed inthe body A. In plate H is a screw-threaded aperture, through which passes the screw-threaded rod K, which enters and has its bearing in a recess, L, also formed in the body A and pret'- erably placed between the recesses Gr. The rod K is provided with a handle, M. By turning the handle M in one or the other direction the plate H is caused to move up or down on the rod K, the plates I and J remaining and sliding in the recesses G. In this way the strap E is loosened or tightened, as desired. The two plates I and J furnish a tirm support for the plate H, and prevent its being pulled to one side bythe strain of the strap. The use of two plates entering the strop-body is especially advantageous, in that all of the strain of the strap in a sidewise direction is received by these plates and does not come upon the screw-rod K, as might be the case were only one plate used, so that there is, therefore, no tendency of the plate H to bind against the rod K. At the saine time this device is easily made and applied, the plates H 'I J being preferably cast in one piece, and requiring no extra fastening to secure them to the strop-body.

I am aware that razor-strops have hitherto been constructed. having a loose strap passing over two sides ot' the body and a tighteningnut arranged in the loop of the strap, which nut is provided with two projecting arms entering the strop-body. I am also aware` of United States Patent No. 252,199, granted to Emerson, January 10, 1882, in which the loose strap passes over one side of the strop-body and is secured to a tightening-nut, which is provided with one slotted arm entering said body. These devices I do not claim, inasmuch as they dii'er from mine materially. My principal object is to support and brace the tightening-nut by means of the two projections thereon entering the strop-body, so that the strain or pull of the strap as the nut is drawn outward, although it is applied on one side of the nut, cannot cause said nutto be canted or bent over.

I claim as my inventionl. In combination with a razor-strop body, a threaded rod entering a recess therein, and an extensible strap attached at one end to the extremity of said body, the tightening device herein set forth, consisting of a metal plate secured to the free end of the strap and havingtworectangularprojections,whichenter recesses in the strop-body, anda threaded aperture to receive the threaded rod, substan-4 tially as described.

2. In combination with a razor-strop body, the three platesl H I J, rigidly attached together, two of said plates entering recesses Gr in said body, the strap E, attached to the body and to the plate H, and the threaded rod K, passing through the threaded plate H and entering a recess in the body, substantially as described."
