' SPECIFICATION forming part of Letters Patent No. 276,092, dated April 17, 1883.

Application filed March 5, 1883.

To all whom it may concern Be itknown that I, AUSTIN V. M. SPRAGUE, of Rochester, Monroe county, New York, have invented a certain new and useful Improvement in Razor-Strops; and 1 do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of my improved 1o razor-strop. Fig. 2 is a perspective view of one end broken oft.

My improvement relates to razor-strops in which a bone is used on one side and a leather strap on the other, the intermediate body por- 15 tion being wood.

The invention consists in the combination of a concave or hollow wood body, a strap stretched from end to end over the concave, and a C-shaped spring at one end, attached to 20 the wood, resting under the leather, and serving to keep it taut by its elasticity, as hereinafter described.

Inthedraivings,Ashowsawood blocl:,which forms the body of the instrument, having at 2 one end a handle, B. The top ofthe block is hollow or concave, as shown at a, and the end farthest from the handle is rounded, as shown at b.

G is a hone-surface on the plane side of the 0 block, and D is a leather strap permanently attached at both ends and resting over the concave a.

E is a metal spring, of C form, attached fast by screws or other means on the under side 5 of the block, thence extending up around the rounded end I) of the block, being of greater (No model.)

diameter than said rounded end, and finally turninginward horizontally, as shown. This spring forms a curved bearing over which the leather pass-es, and, being under strain when the leather is applied over it, it constantly exert s a drawing action on the leather by its elas: ticity and keeps the leather always straight and taut, but with just enough of relaxation to slightly bend downward under the pressure of the razor in stropping.

By the means above described screws and other devices for stretching the leather by end movement may be avoided, and much expense is saved in manufacture, and a much better strop is produced, since the spring, by its stilt and broad bearing under the leather, has a tendency to draw it in astraight line and prevent any twist.

If desired, springs may be used at both ends of the strop,or at either end, and,if desired, the straps may be duplicated, or two or more used on the different faces of the block.

Having described my invention, I claim In a razor-strop,thecombinationof the wood body, the leather strap,and a spring attached to the body, resting under the strap, and serving to hold the-strap straight by the elasticity of the spring, as herein set forth.

In witness whereof l have hereunto signed my name in the presence of two subscribing witnesses.
