RAZOR-STROP.

SPECIFICATION forming part of Letters Patent No. 551,331, dated December 10, 1895.

Application filed January 11,1895. Serial No. 534,512 (No model.)

To all whom, it may concern 3e it known that I, HARDING F. GRAY, a citizen of the United States, and a resident of Passaic, in the county of Passaic and State of New Jersey, have invented a certain new and useful Improved Razor-Strep, of which the following is a specification.

My invention relates to razor-strops put up in a form convenient for travelers, the object being to provide the usual and popular form of loose strop with a casing in which it may be stored when not in use and providing for making it automatically returnable into the casing when not in use.

\Vith this object in view my invention consists in the construction and combination of parts, as hereinafter fully described, and set forth in the claims.

In the accompanying drawings, which form a part of this specification, Figure 1 represents an axial longitudinal section of my strop rolled up within its casing. Fig. 2 represents a transverse section of said strop. Fig. 3 represents an end view of the hollow roller and an end plate therefor. Fig. at represents in transverse section two forms of strop.

In the drawings, A. indicates the casing for V the strop, which may be made of any material desired and ornamented in any suitable manner. This casing is provided with a ring B, by which it may be hung upon any suitable hook.

Within the casing is mounted a hollow roller 0. Upon this roller is secured the strop D, which has at its end the usual holdingloop E, a slit, as F, being formed in the easing from which the end of the strop bearing said loop protrudes.

It will be noticed that the roller G is so constructed that it is of greater diameter at its middle point than at any other, thereby causing it to taper gradually toward its ends. This point of greater diameter coincides with the longitudinal middle line of the strop. This form of roller provides for an even return of the strop within the casing.

The hollow rollermay be mounted in various ways within the casing and the spring for returning the strop to place may be constructed and located difterently from the form shown in the drawings; but I prefer to use the construction as illustrated. In this construction a right-handed screw, as G, is inserted through one head of the easing into the center of the hollow roller and a lefthanded screw H is inserted into said roller through the other head of the casing. These screws are secured against rotation in said head in any suitable manner, being shown in the drawings as square at the point of union between them and said heads. Upon each screw is placed a nut I, which is of such formation (preferably circular and provided with projections) as to co-operate with suitable guides formed on the interior of the roller 0. Each of said nuts in the construction shown consists of a ring through which pass pins 5. These pins at their outer ends project into the guiding-grooves (3, formed in the inner surface of said roller, which grooves extend longitudinally of the roller, as shown. Said pins also enter the central opening of the ring and project into the threads of the screws G and H. The threads of these screws are of coarse pitch and there are by preference two threads upon each screw. About each screw is placed a spiral spring K. This spring bears against the nut I at one end and a suitable abutment at the other, preferably a plate, as L, provided with lugs fitting into notches in the end of said roller, so that the said plate may turn with the rollers and thereby provide against any torsional strain upon the springs K, such as would result from their bearing directly upon the heads of the casing. Suit-able stops, as 7, are placed at the inner ends of the screws G and H to limit the movement of the nuts I.

I have shown the heads of the casing as screwed upon the body portion, but obviously they may be connected thereto in any other suitable manner.

The parts as shown have been specially designed for convenience in assembling them. Their form and shape may be varied, if desired, in order to facilitate the mode of manufacture and assembling without departing from my invention.

The operation of the improved article is as follows: In the drawings the strop is shown in its normal position. When it is to be used the case is hung upon some suitable hook and by pulling upon the loop E the strop may be drawn out, which act causes the roller C to revolve, carrying with it the nuts I, which travel around their respective screws, thereby compressing the springs K. Upon releasing the strep it will again be rolled up,

because of the sprin s K expanding and forcing the nuts I along the screws, thereby r0- tating the roller C. One screw and one nut might be used, but two are preferable, as by them a steady and even action of the roller 0 is obtained.

The strep which I prefer to use consists of a strip of leather M, having formed upon one side thereof a fold of porous material such as canvas or any other substance 0 which shall readily allow a finely-powdered or semi-plastic abrading material to pass through its meshes or pores. Between such porous material and the leather or within the fold made entirely of said material, as shown at O, I place the abrading material P. This constitutes the rough side of the strop while the leather furnishes the smooth or finishing side.

\Vhat I claim as my invention is- 1. The combination, substantially described, of a hollow roller provided with guides extending longitudinally of its inner surface, a nut fitted to slide along said guides. a fixed screw within said roller upon which said nut is free to turn, a spring exerting its tension upon said nut, and a razor strep secured to said roller and adapted to be rolled thereupon by the action of said spring.

The combination with the casing, of the hollow roller therein provided with longitudiiial grooves on its interior, a right-handed screw fixed in one end of the casing and extended into said roller, a lefthanded screw fixed in the other end of the casing and also extended into the roller, a nut upon. each screw provided with projections fitted to slide in said grooves, a spring about each scre acting upon its respective nut to force it along the same, and a razor strep connected to said roller and. adapted to be wound thereupon by the co-action of said springs.

Signed at New York, in the county of New York and State of New York, this 10th dav of January, A. D. 1895.

HARDING F. GRAY.
