E. H. PENFIELD, OF MIDDLETOWN, CONNECTICUT.

METALLIC GROMET.

Specication of Letters Patent No. 5,779, dated September 19,1848.

the inside ferrule, which is left smooth on itsy edges, as a common cylindrical socket. f After cutting a hole in the sail .just large enough to receive the gromet the outside one or one having teeth is put through. the hole, the inside one or one with a smooth edge is then put through, and a conical pin is then drove through which turns the teeth of the outside one into the cloth and the edge ofv the inside one firmly onto the rim of the outside one, thereby irmly iiXing it.

There are many advantages that might be pointed out in using this gromet well known to ship builders and sailors. First they will always keep their place, as the teeth becoming iixed in the sail will never allow them to move or allow the cloth to be drawn outfrom between the ianches by any strain on the sail. Second, being composed of brass the sail cannot contract around them in damp weather so as to prevent the free use of the cords and third, they are cheaper than any other hole` can be made for the purpose. v

To enable others skilled in the art to make and use my invention, I will proceed to describe it with reference to the annexed drawings making a part ot' this specification.

A B, Figures l and 2, show both parts of my gromet in perspective,

a, a, &c., Fig. 2, represent the teeth on the outside ferrule.

a, Fig. l, represents the inside errule and make them of brass and raise them in/a die f suitable for that purpose, thewidth of the ferrule in all cases must correspond with the thickness of the sail, thereby preventing any motion of the gromet in the sail, and prerom the gromet, and thereby tearing the cloth and loosening the gromet.`

I am aware that gromets have been made of a socket with a flanch raised on one of its ends, and a washer put on the other end, after passing the socket through the cloth; when, by setting down the end of the socket over the washer it holds the cloth between to' smooth edged anches, which will however allow the cloth to be drawn 'out whenever there shall be` great strain on it; therefore, I v do not claim the socket or washer, as such, nor the manner of locking them together, as my invention, but

l/Vhat I do claim as my invention, and desire to secure by Letters Patent, is-

Making a gromet of a metallic cylindrical tube, or Jferrule, having a solid disk, vor rim on one edge,` as seen in Fig. 1,) and a similar shaped solid disk with a ferrule, made with teeth, or points, (as. seen in Fig. 2,)V which two together, pass through the cloth and lock in such a manner that the teeth, or points, a, a, &c., Fig. 2, may turn over and press upon the cloth, to prevent its being strained out, andtorn or injured, by,V v

vthe strain on the sail, the whole constructed,

and attachedv substantially, as herein described. I

In testimony whereoil I the said E. H. PENFIELD subscribe my name in presence of the witnesses whose names are hereto subscribed.
