SWIVEL-RACK FoR LooMs.

SPECIFICATION forming part of Letters Patent No. 251,664, dated December 27', 188 1. Application led December 27, 1880. (No model.)

To all whom 'it may concern:

Be it known that 1, BUCKLEY WEsroN, of

Paterson, in the county ot' Passaic and State of New Jersey, have invented a new and useful Improvement in Swivel-Racks for Looms, of which the following is a specication.

My invention relates to improvements in swivelracks for looms, and its objects are to provide improved means for throwing and to prevent the rebound of the shuttle.

My invention consists in the combination, with the rack-bar, swivel-shuttle, and pick-bar,

on wires attached to the rackbar and provided with lugs designed to drop in recesses near theextremities of the pick-bar, said pins being actuated by springs, substantially as hereinafter described, whereby they are caused to engage in holes formed in the shuttle, as setl forth.

The construction and operation will be more particularly explained hereinafter, with reference to the accompanying drawings, wherein- Figure l is a front elevation, partially in section, of my improved swivel-rack. Fig. 2 is a vertical cross-section on line x m of Fig. 1. Fig. 3 is a section on line y y ot Fig. 1, and Fig. 4 is a horizontal section on line zzof Fig. l.

Similar letters of reference indicate correspondin g parts. Y

A is therack-bar, which is of suitable length and formed at its under side with an opening, a. At the lower edge of the bar A an L- shaped slot, b, is formed, that receives the shuttle B, so that the shuttle' isA sustained by the bar at either side of the opening to which it may be slid in the groove.

C is the pick-bar, inserted beneath a shoulder on the upper part of the bar A, and held in place by lugs c c at the under side and d d at the front, so that bar C may more length- Wise, the extent of movement being limited by lugs c. The bar G is provided with fingers e `at its ends, that project downwardjacross the path of the shuttle, and with a handle, f, by which the pick-bar is to be moved.

The opening ein rack-bar A is shown as l about the length of the shuttle; but it may be longer, if desired-say, fromthree to tive inches.

To the bar A, at the upperside of opening a, plates g q g are attached so that they project into the opening, with their lower ends about on line with the bottom of bar A. These plates g are placed equidistant from each other and the sides of the opening, and are formed with L-shaped slots corresponding with slot b of bar A, so that the shuttle may pass through said slots in passing from one end of the rackbar to the other.

Upon the face of bar A, at each side of the opening a, a pin, h, is fitted in lugs t', so as to be capable ot' vertical movement, and to each pin is connected the end of a spring, k, that tends to force the pin downward. The pins li arehung on the ends of wires or rods l, that are pivoted at the mid-length of bar A, which wires are formed with lugs l', that rest on the upper side of bar C, so that the pins li are `held upward, except at the extremes ot' movement of the pick-bar, when the lugs l drop into inclined recesses o on bar C, and the pin above the shuttle enters a recess, p, in the upper side thereof.`

The rack-bar A is to be attached to the lay of the loom in the manner shown in English Patent No. 3,239 of 1869, in order to permit vertical movement of bar A, so that it can be brought down in front of the reeds when required for use. The relative position is shown in the drawings, wherein the lay is shown by dotted lines at D. In this position the warps that are opened for the swivel-shuttle to pass extend through the opening a of the nachbar, so that when the swivel-shuttle B is thrown it passes through the shed. The ligure required may thus be produced in the fabric, andthe shuttle being held up by the plates g a wide ligure may be formed. It will be understood that thisrack-bar and shuttle are used in connection with the ordinary ground-shuttles and Jacquard mechanism. l

By the use of plates ggures may be formedr IOO recesses o raise the pinshas the bar() is moved The combination of springs lr, pins h, wires to throw the shuttle, and as the bar C reaches Z, having lugs l', pick-bar C, having recesses Jthe end of its movement before the shuttle o, swivel-rack A, and recessed shuttle B, subthe piu h in advance of the shuttle which has stantially as and for the purposes specified.

5 fallen is raised by Contact with the shuttle until it is over the recess p, when the pin falls. BUCKLEY WESTON. [L S.]

This improvement may be applied to either hand or power looms. Witnesses:

Having thus fully described my invention, S. A. MCGREGOR, 1o I claim as new and desire to secure by Letters W. P. MGGREGOR.
