LUG-STRAP FOR LOOM PlCKER-STICKS.

SPECIFICATION forming part of Letters Patent No. 408,703, dated August 13, 1889.

App1icati0n filed January 28, 1889. Serial No. 297,848. (No model.)

To all whom it may concern:

Be it known that I, CHARLES C. FOLLETT, a citizen of the United States, residing at Vaterville, in the county of Kennebec and State of Maine, have invented certain new and useflll lllllJl'OVGDlGlltS in Lug-Straps for Loom.

Picker-Sticks and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appert-ains to make and use the same.

My invention relates to lug-straps for loom picker-sticks, such as have hitherto been made of leather. These straps form the immediate means by which the picker-stick is actuated, and they are secured to the end of a horizontal rod in such a way as to form aloop at the end, through which. loop the picker-stick is passed. The strain on the lug-strap caused by the'sudden shock with which the pickerstick is projected forward is so great that it has always been necessary to usethe best quality of leather, and in many looms the leather has been used of a double thickness. The strain on the leather strap causes it to stretch and to increase in length, in consequenee of which it must be frequently adj usted longitudinally to give the proper throw to the picker-stick. It is thus soon destroyed, lasting on an average about six weeks.

The object of my invention is to construct a strap which shall bemore strongly made and less liable to destruction than the leather strap already spoken of, and which shall at the same time possess sufficient elasticity to do the work properly and to prevent breakage of the parts. It has always been thought that a very considerable degree of elasticity was necessary in the lug-strap to properly throw the pickerstick; but I find from experience that when the motion is delivered to the picker-stick through the medium of a rigid strap having an elastic cushion at the point where the concussion takes place much better results are obtained than by a more elastic strap.

My invention consists of a metal strap having a cushion of elastic material at the bend or heel.

In practice I prefer to make my strap in the 01d way-of leather, with re-enforcing bands of metal secured to the outside and extend ing lengthwise of the strap.

As shown hereinafter, there are several ways in which my invention can be carried out, and I do not wish to limit myself to any particular form.

I illustrate in the accompanying drawings several forms of lug-strap made according to my invention.

In the drawings, Figure l is a side elevation of one form of my strap in position in the loom. Fig. 2 is a perspective view of the same form of strap. Fig. 3 is a side elevation of another form. Fig. 4 is a perspective view of a third form.

A represents the leather strap, of ordinary form, having longitudinal slots a, for the passage of the bolt 6, by which it is secured to the picker-rod F.

In the forms shown in Figs. 1 and 2 I socure the parallel metal straps B to the outside of the leather strap, one on each side of the slots at. The straps of metal are secured to the leather by means of staples b, which are clinched 011 the inside of the leather. By this manner of securing the two parts together a little motion is allowed between the metal and the leather. I

0 represents the ordinary picker-stick, and D the loop attached thereto for supporting the lug-strap. The washer 6, through which the bolt 6 passes, clamps the two straps B B solidly in place.

In Fig. 3 I show a form of strap made with the leather strap of the ordinary form, and the metal strap constructed with two parallel bars and connecting-webs between them, all being formed in one piece.

In Fig. 4 I show the metal strap having the necessary slot for the passage of the bolt and an elastic buffer or cushion A in the bend or heel of the strap.

These Various forms of my invention may be used as circumstances require.

I claim 1. The lug-strap for loom pieker sticks, consisting of a metal bar bent or folded to form a loop, combined with a leather or other elastic lining for said strap extending from end to end thereof, substantially as shown.

2. The lug-strap for 100111 picker-sticks, con- In testimony whereof I have hereunto set sisting of a pair of metal bars bent or folded my hand, in the presence of two witnesses, 10 on their centers and einbraeinga single inner this 26th (la of December, 1888. strap or linin of elastic material havin lonr v 5 gitudinal slots in its ends, said metal strap CHARLES FOLLEJ being secured to said inner strap, one at each \Vitnesses: side of said longitudinal slots, substantially S.
