METALLIC HEDDLES.

Specification of Letters Patent No. 8,662, dated January 13, 1852.

T0 all whom t may concern Be it known that I, JACOB SENNEFF, of the `city and county of Philadelphia and State of Pennsylvania, have invented 'a new Vand useful Improvement in the Construcing through the casting forming the eye.

In the use of the commonA wire heddles, much diiiiculty is experienced from the threads of the warp not working freely through the harness, and the great liability of the fibers of the warp felting or working into the twist of the wires, above and below the eyes. The cost of the material and the weight of the common wire harness are also objectionable-being made double and necessarily of heavier wire than is required to make my single wire harness. There are other objections to the use of the thick double strand twisted wire harness, which could be named, but the above will suice to show the importance of my invention and improvement. My improved harness is designed to remove these objections, and the nature of `it consists in casting the eye A on the single wire heddle B in a novel and peculiar manner.

To make'this heddle, a suitable mold of the shape of the required eye should be lirst prepared, in which the eye is to becast on the single wire. The wire is bent slightly at the middle where the eye is to be cast; it is then placed in the mold and the molten metal introduced; when suiiiciently cool the mold is opened .and theheddle removed. In this manner the heddles are made.

The molten metal may be cast over the Wires in sheets or plates, and the eyes be subsequently punched from the sheets or plates when the latter are sufficiently cool to admit of the punching operation.

Several separate heddles may be formed in a single moldy with the eyes cast complete. The eyes may also be cast in glass or other suitable material.

Owing to the friction being so much reduced by the use of my improved single wire cast eye harness, much less sizing will be required on the warp; and perhaps in practice it may be entirely dispensed with.

l/Vhat I claim as my invention and desire to secure by Letters Patent is Casting the eye on the wire which constitutes the heddle, harness, or heald, through which the warp passes, in the manner and for the purpose set forth, producing a heddle much superior to any other known or used, and which will remove many of the diiiculties heretofore experienced in the use of the common twisted wire heddle.

In testimony whereof I have hereunto signed my name before two subscribing witnesses.

JACOB SENNEFF.
