METHOD OF MANUFACTURING SEWING-THIMBLES.

SPECIFICATION forming part of Letters Patent No. 247,384, dated September 20, 1881.

Application filed June 13, 1881. (No model.)

To all whom it may concern:

Be it known that I, HUGH MGDOUGALL, of the city of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in the Manufacture of Sewing-Thimbles, of which the following is a specification.

Sewing-thimbles as commonly made have a rim or band around their larger end, which is thicker than the portion above it, and which has heretofore been formed either by making the whole thimble ofmetal of the desired thicknest of the rim, and turning it off nearly to its end, or by folding over one edge of the blank to give the desired thickness.

The object of my invention is to simplify the manufacture of thimbles; and my invention enables me to produce thimbles having embossed ornamentation above the rim without any appreciable increase in cost.

To this end theinvention consists in a novel method of making a thimble-namely, in so rolling a blank as to form a thick portion for the rim, and, ifdesired, also an embossed ornamentation, in cutting or trimming the blank to the desired form, in bending the blank and soldering its ends together, and in closing the end thereof, all as fully hereinafter described.

In the accompanying drawings, Figures 1 and 2 represent respectively a plan and edge view of a piece of metalfro'm which the thiinble blank is produced. Figs. 3 and 4 represent respectively a plan and section of the blank after being rolled. Figs. 5 and 6 represent corresponding views of saidblankafter' it is trimmed. Fig. 7 represents a perspective view of the incomplete thimble formed byjoining the two ends of the blank; and Fig. 8 represents a perspective view of the thimble having its upper edge turned in to partly close the end thereof.

Similar letters of reference designate corresponding parts in all the figures.

A, Figs. 1 and 2, designates the piece ofcopper, brass, silver, or other metal or composition from which the thimble is to be formed. The piece A is first passed between rolls properly engraved, by which operation it is rolled out into the shape shown in Figs. 3 and 4. By this rolling there is formed an arc-shaped head, a, which is to form the rim of the thimble, and, if desired, embossed or relief ornamentation b may be produced above the head a. without increasing the cost of manufacture. The principal portion of the blank A, or that portion beyond the ornamentation b, is rolled considerably thinner than the head, as seen in Fig. 4, whereitis shown as ot'abouthalt'the thickness. The blank A is next trimmed on all sides to give it a segmental shape, as seen in Fig. 5, after which it is rolled or bent into tubular form, and has its ends soldered together at c, as seen in Fig. 7. The upper edge of the thimble is then folded or turned inward, as seen in Fig. 8, to partly close the end, leaving a hole, (I, which may be closed by a small circular disk secured therein.

By my invention 1 simplifythe manufacture of thimbles, and I enable thimbles having embossed ornamentation to be produced without materially increasing the cost of manufacture.

What I claim as my invention, and desire to secure by Letters Patent, is-

The improved method ofmaking a thimble, consisting in first so rolling a blank as to form a thick portion for the rim, or a thick portion and embossed ornamentation, next trimming said blank to the desired form afterward bendin g said blank into tubular form and soldering its meeting edges together, and finally closing the end of the tube, substantially as and for the purpose specified.
