RAZOR-STROP.

SPECIFICATION forming' part of Letters Patent N o. 776,213, dated November 29, 1904.

Application filed August 29, 1904. Serial. No. 222,611. (No modela To ttl/f whom t may concern,.-

Beit known that I, GRANT C. BLAsDELL, residing at Towanda. in the county of Bradford and State of Pennsylvania, have invented certain new and useful Improvements in Razor- Strops, of which the following is a specication. Y

My present invention relates to improvements in that type of razoi-strops in which the strop is spring-wound within a suitable casing', and it more particularly seeks to provide improvements in that form of strop disclosed in my Patent No. 572,784, dated December 8, 1896.

My present invention comprehends an improved arrangement of a casing, a springwound drum, a strop attached thereto, and a special means for cooperatively joining the several parts and rendering their construction economical and simple.

Another feature of this invention lies in the improved means provided for detachably con-v necting the end of the strop to the windingdrum, and in its still more subordinate features my invention consists in certain details and peculiar construction of parts, all of which will be hereinafter fully explained, and specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which- Figure l is a perspective view of my improved raZor-strop. Fig. 2 is a cross-section of the same on the line Q 2 of Fig.` l. Fig. 3 is a transverse section of the same on the line 3 3 of Fig. 2. Fig. 4.- is a detail view showing one way of detachably connecting' the strop end to the winding-drum. lFig. 5 is a detail view of the metal fastener-strop shown in Fig. 4L. Fig. 6 is a detail 'View showing the blank from which the winding-d rum p0rtion f2 is formed. Fig. 7 is a detail view of a modified form of strop-fastening means hereinafter referred to. .Fig 8 is a detail View of the same. Fig. 9 is a detail view which illustrates the correlative position of one of the post or shaft ferrules, the shaft, and the adjacent end cap. g

In the present form of my invention the casing consists of the wooden end members a a', having annular grooves a2 on their inner faces arranged to receive the edges?) of the sheet-metal casing B, the ends of which are brought together and terminate in turned-up beads to leave a slotway X for the strop, as shown. The shaft or post E is also of wood and is of such length that it extends entirely across the casing B, and the ends of said shaft are arranged to iit into circular sockets L3 in the end members or caps a, and to provide for holding the shaft from turning in the end caps c the said ends have fitted therein metal ferrules or sleeves (Z d'. These ferrules, as best shown in Fig. 9, are split and have their outer ends turned slightly inward, as at (ZX. By reason of such special formation of the ferrules or sleeves the outer ends of the said ferrules will expand when the shaft or post is tightlyidrawn endwise into the axially-disposed sockets in the end caps c, and thereby securely grip or clamp the ends of the post or shaft to hold it fromv turning. The circular end pieces a, a are held up against the ends of vthe shaft E and the casing by the screws g that engage the shaft ends, as clearly shown in Fig'. Q.

In my present form of strop I use a cylindrical sheet-metal drum F, which is formed of circular end pieces ff, having axle-openings'f for the passage of the ends of the shaft E and the sheet-metal piece f2, that is bent up cylindricall y with the ends separated to form a wide opening Gr, the purposes of which will presently appear. The peripheral edges of the disk-like end pieces. f are bent upwardly to form flanges f5 f5, and at suitable intervals at their bent edge the pieces 7" have coneentrically-arv ranged slots f for the passage of the tongues 4f of the sheet-metal member-f2, which tongues are bent over the outer faces of the end piece f and serve to lock the end pieces of the cylindrical piece or shell together. It will be noticed that between the ends of the members f2 the fianges f5 on the end pieces fare omitted to permit of the use of a wide strop O, as shown in Fig. 4.

H designates aspiral spring mounted around the shaft E, one end of which is bent to enter a slot e in one end of the said shaftE and the other end of which terminates in a hook e2 to engage with the inturned iiange fs on one of the ends of the circular drum-piece f2, as clearly shown in Fig'. 3. This spring H in the present form of my invention is in the nature of a tapering coil, which increases in its diameter from that end of the spring that interlocls with the shaft E to the end that hooks into engagement with the drum-casing. By increasing the diameter of the coils in the manner stated and shown danger of the spring coiling tightly around the shaft before all the tension thereto has been drawn out is effectively overcome, and, furthermore, the coils of the spring at the large end closely abut, while the remaining coils are separated or spread widely apart, such arrangement of the coils being especially designed to prevent the spring falling over, crowding, or buckling when tension is applied. The aforesaid arrangement of the spring H, I have found very desirable, since all tendency of the coils as they increase in number as the tension is applied to the spring by pulling out the strap crowding toward that end connected with the slotted portion of the shaft E is practically overcome.

To provide for readily connecting the strop end with the winding-drum, the upper end of the strop in the preferred form (see Figs. 3 and A) is provided with a plate l0, having a series of bendable tongues l()a projected from its opposite edges, one of which when the tongues are arranged as shown in Fig. 4: is passed through and clamped upon one edge of the circular portion f2 of the winding-drum, which end has slots to receive the said tongues, and the other side of the plate l0 is made fast to the strop end, as shown.

Instead of using the tongue-shaped member shown in Fig.-8 one end of the circular portion f2 of the drum may be formed with upturned tongues 2f, as shown in Fig'. A7, to engage the slots am in the upper end of the strop O.

The strop O has a handle P for pulling it out, and the casing B has a swivel-eye r, by which the casing may be suspended from a hook or other device.

From the foregoing, taken in connection with the accompanying drawings, it is believed the advantages of my invention will be readily understood.

/Vhile the same general characteristics of my present invention appear in my patent before referred to, my present form of strop clearly dierentiates from the form shown in my patent in the peculiar manner in which the shaft is mounted in the end heads, the special construction and application of the spring H, the manner in which the drum-casing is constructed, and the means for detachably connecting the strop to the said drumcasing.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A razor-stropping device provided with a case having a spring winding-drum thereon formed with a transverse opening' in its cylindrical portion; in combination with a razorstrop provided at its ends with a metallic member that is detachably connected to the upper end of the strop, one end of the cylindrical portion of the drum having slots and the metallic member or plate having bendable tongues for engaging the said slots as set forth.

2. A raZor-stropping device which comprises the case, the shaft extending centrally through the same from end to end, the winding-drum, the spiral spring whose Coils are of variable diameters for a portion of the length of the spring and the remainder of said coils of uniform diameter, one end of the spring being detachably connected to the end of the winding-drum and the other end detachably connected to the shaft, and a strop connected to and adapted to be wound on the windingdrum as set forth.

3. A razor-stropping device provided with a case which includes end caps each having a central socket on its inner face, a shaft whose ends lit in the said socket, a split ferrule mounted on each end of said shaft whose outer edges are bent inwardly, a spring windingdrum mounted on said shaft, said drum and the casing having transverse slots, and a strop movable through said slots and having its upper end connected to said winding-drum as described.
