To all'whom it may concern: Be it known that I, Sevens BANKS, a citizen of the United States, residing at Concord, in thecounty of Cabarrus and State of North Carolina, have invented certain new and useful Improvements in Lug-Sticks for Looms, of which the following is a specification.

This invention has reference to lug sticks: for use in looms, and its object is to provide,

a device to replace the lug straps in common use employed for impelling the picker stick.

It has heretofore been customary to make the lug straps of wood, canvas and metal,

the construction being relatively expensive and short-lived.

prolonged while the cost of the device is very largely reduced.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding,

however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed and modified so long as such changes and modifications mark no material departure-from the salient features of the invention as; expressed in the appended claim.

In the drawing Figure '1 is a side elevation of a lug stick i I as applied to a picker stick.

Fig. 2 is a plan view of the lug stick on a larger scale than that of Fig. 1. J 1 Fig. 3 is a section on the line 3 3 of Fig. 2.

In Fig. 1 there is shown a picker stick'l" which may be of ordinary constructionand mounted in the usual way, wherefore, no particular description of the picker stick is needed.

In order to actuate the picker stick to throw the shuttle, therefis provided a device which, because of its general construction,

has heretofore been known as a lug strap. Such lug strap comprises an elongated wooden member to one end of which one end of a link is attached, the link receivlng motion from a suitable part of the loom structure to intermittently move the picker stick nfue-s'rmx 'F'on Looms? 7 Siicification of Letters Patent.
