IMPROVEMENT IN THIMBLES FOR SHIPS RIGGING.

Specification forming part of Letters Patent No. 139,230, dated May.27, 1873; application filed March 18, 1873.

To all whom it may concern:

Be it known that I, THOMAS G. BELL, of

of New York, have invented certain new and useful Improvements in Thimble for Ship- Rigging, 8vo.; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon, which form a part of this specification.

The nature of my invention consists in a pear-shaped thimble with oblong pin-hole, to be used in ships rigging, Ste., in lieu of the ordinary round thimble, as will be hereinafter more fully set forth.

. In order` to enable others skilled in the art to which myinvention appertains to make and use the same, I will now proceed to describe its construction and operation referring to the annexed drawing, in which- Figure 1 is a plan view; Fig. 2, a side view og my invention; and Fig. 3 is a section thereo A represents the thimble, made of the cast metal ordinarily used for such articles, or of any material that will answer the same purpose. The general outline of the thimble is pear-shaped, as shown, and provided with an oblong pin-hole, B, having parellel sides, reeeiving a pin of corresponding form, to prevent the thimble from canting with the greatest stress the rope is capable of standing. The thimble has a groove around its outer surface, terminating at a point at a or coming together 1 at that point, as shown in Fig. 3. The groove upon either side of the thimbleforms a triangle with the extremities of the minor axisrepresented by dotted line b, Fig. 3-of the v,

thimble, the bott-om of the groove from `the points c c being on a straight line to the point a.

I am aware that an ovall thimble with central oblong perforation has been used; also, a

thimble of pear shape having a corresponding` opening; but my device di'ers from those before used by having an oblong pin-hole having parallel sides, and in having the groove upon the outside of the4 thimble terminating at the point thereof, and in having the bot- 'tom of the groove upon a straight line for or cast thimble' described, provided withthe Woblong pin-hole B and the groove formed upon a straight line from c to a, and terminating at the point a, substantially as and for the purpose specified. f

In testimony that I claim the foregoing' as my own I aiiix my signature in presence of two witnesses.

THOMAS G. BELL. Witnesses:

WILLIAM PHIPPs, JOHN PETERS.
