WIRE-LIFT NEEDLE FOR JACQUARD MACHINES.

SPECIFICATION forming part of Letters Patent No. 394,800, dated December 18, 1888. Application filed June 2, 1888. Serial No. 275,887. (No model.) I

To all whom, it may concern:

Be it known that I, \VILLIAM XVATTIE, a citizen of the United States, residing at orcester, in the county of orcester and State of Massachusetts, have invented certain new and useful Improvements in \Vire-Lift Needles for Jacquard Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, which, in connection with the drawings; making a part of this specification, will enable others skilled in the art to which my invention belongs to make and use the same.

My invention relates to wire-lift needles for Jacquard machines in which the top of the needle is bent over to form a hook to work in .conjunction with the lift-plate or griff, and

the bottom of the needle is bent backward upon itself, forming a U, which serves to guide the needle in a slot in a guide-plate, the end of the back part being bent into a hook, which works in conjunction with a lift-bar on the guide-plate.

The object of my invention is to tie together and confine .in a cheap and effective manner the parts of the U of the needle, so as to prevent the needle from being turned out of its proper position in the guide-slot, and the ma chine being thereby deranged.

Referring to the drawings, Figure 1 represents a wire-lift needle of my improved construction, with a detached section of the guideplate. Fig. 2 is a plan of one of the confiningbands which tie the two parts of the U together. Fig. 53 represents the band shown in Fig. 2 after it is set or compressed upon the U part of the needle; and Fig. at is a plan of a detached portion of the guide-plate, showing the ordinary construction of the wire-lift needles, with one in its proper position and one turned out of position, as will be hereinafter fully described.

In the accompanying drawings, 1 is the principal wire of the needle, and 2 the part bent back upon itself. is the confining-band, which ties the two parts together. 4 is the top hook, and 5 the grid with which it works. 0 is the lower hook; '7, the lift-bar on the guide-plate S, and 9 the slot in the guideplate.

The lift-needles are placed in the Jacquard machine in rows as near together as they can be worked, and the cords connecting them to the loom-harnesses or other mechanism which it is desired to work by the jacquard are attached at the lower end, 10.

The mechanism by which the griffs 5 and the guide-plates 8 are reciprocated, and the indicator-needles which effect the engagement and rise of hook 4 with griff 5, or the missing of griff 5 by hook 4 and the descent of the needle with the-plate 8, form no part of my invention and are not shown, and the same may be arranged in various ways, as will readily be understood by those familiar with wirelift Jacquard machines. If in practice the cords could be made always to pull directly down from the center of the bend 10, the trouble which my improved needle is intended to obviate would not occur;

but it frequently happens that the cords pull in such a way as to spring the two parts of the U of the needle toward each other near hook 6 and allow the needle to spring into the position shown at 11, Fig. 4, the proper position being shown at 12, same figure.

W hen in the position 11, the needle cannot work properly, and the hook 6 may become entangled with its neighbor. It often happens that the needles are in this way bent out of shape, necessitating the stoppage of the machine till they can be replaced.

hen the band 3 is in place and compressed upon the U part of the needle, the needle cannot turn in its slot 9, and the hooks 4 and 6 must always be in proper position for engagement with the lift plates or bars. The band 3 may be more firmly secured on the needle 1 by means of soft soldering, if desired.

It will be observed that the part of the hook 6 adjoining the band 3 is bent outward, so that when the hook rests upon the bar 7 there is a space between the band 3 and the side of the bar 7, and also that the slot 9 is so placed in the guide-plate 8 with reference to the bar 7 as to keep the band 3 from touching the bar when the needle slides past it. The object of this construction is to prevent the band 3 from touching the bar, for if it was allowed to come in contact with it, it would soon wear through the light band and destroy the tie.

Having thus described my invention, what I claim as new, and desire to secure by Letlihereof, of the lift-hm, and the gnhie-plate tel-s Patent, having a slot, E), therein, [or The purpose 1o 1.
