LOOM FOR WEAVING WIRE FABRIC.

SPECIFICATION forming part of Letters Patent No. 312,008, dated February 10, 1885.

Application filed February 13, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that I, THOMAS PATTERSON, of Gortland,county of Gortland,and State of New York, have invented a new and Improved Loom for Weaving Wire Fabrics; and I do hereby declare that the following is a full, clear, and exact description o'f the same, reference being made to the accompanying drawings, and to letters of reference marked thereon.

This invention relates to looms for weaving wire fabrics or other cloth; and it has for its objects a positive shuttle motion in which the greatest simplicity of construction is secured, and which is not dependent upon springs for changing the motion of the shuttle; also, to provide the loom with carriers which will not be liable to get out of order during operation; and, finally,to so regulate the speed of the shuttle as to give ample time to the action of the parts in changing the shuttle, as more fully hereinafter shown and described.

The objects I attain by the means illustrated in the accompanying drawings, in which Figure 1 represents a general front view of the beater,lay, or lathe and parts connected therewith; Fig. 2, a side or end view of a portion of the loom; Fig. 3, a front elevation of the shuttle complete,showing a portion of the carrier-arms, one of which is partly in section Fig. 4, a top view of theshuttle; Fig. 5, an elevation of the shuttle-body,with one of the carrier-receiving tubes disconnected,and with the pivoted locking-plate, bobbin, and other connected parts removed; Fig. 6, an elevation of the pivoted locking-plate; Fig.7 ,a detached view of one of the trip-springs for moving the locking-plate of the shuttle; Fig. 8, a detached view of one of the half-gears, with its arm attached, and a portion of the rack-barwith which the half-gear engages.

In the drawings, the letter A indicates the lathe, lay, or batten, which is arranged to be moved back and forth upon the bars B,which latter are secured upon the loom frameby means of pitmen 0, connected with cranks D on a driving-shaft, E.

The letter F indicates two segmental toothed gears,journaled in the lathe, lay, or batten upon the studs G, and arranged to engage the teeth of the stationary racks H, so that when the lathe, lay, or batten is moved back and forth the gears will be rotated partially. These gears are provided with arms I, to which the propelling-rods Kare connected, the said rods being also connected to the carriers L, which are arranged to reciprocate in the bearings M, secured to the batten in such manner that when the gears are operated by the movement of the batten the carriers will move to and from the center of the batten for the purpose of carrying the shuttle and shifting the same. The length of the racks corresponds to the length of the peripheries of the segments, and the number of teeth in the racks with the number of teeth in said segmental. gears, and the peripheries of said gears coincide in turn with the length of stroke of the lay, so that when the lay is moved back and forth the segmental gears will be turned alternately half around in each direction. By the peculiar construction of these parts and their relation to each other a very slow speed is obtained for the carriers both on starting and as they approach each other at the center of the loom, where the shuttle is shifted, which allows a better and surer action of the parts in shifting, and obviates the breaking of the weft when starting to enter the warp from either side. This differential speed is obtainedinthe following manner, viz: When the cranks D, which propel the lay, are at or near their dead-centers with respect to the lay,

there will be imparted to the said lay the slow rate of speed of the stroke or beat,at the same time the segmental gears will be revolving,

also at their slowest speed, and as the arms I on said gears constitute cranks,which stand in the same relation to the carriers as do the cranks D to the lay, it will be observed that the speed of the carriers will be reduced to a very slow motion on starting and stopping, and the fastest speed will be obtained at midway between the points of starting to enter the warp, and meeting at the center.

The letter N indicates the warp-drum of the loom, and P the harness, which is worked by the tread-levers R, operated by the cams S. T indicates a guideroller, over which the cloth passes when woven.'

The letter U indicates a spring catch or hook in the end of each of the carriers, which catch extends upward through and above the face of each of said carriers for the purpose hereinafter described. The shuttle consists of a body, V, having at the ends rectangular tubes WV, for receiving the ends of the carriers.

X indicates apivoted locking-plate,having hooked ends as and a projection, Y, provided with an arm, Z, having a slot, A, for the passage of the wire from the bobbin. The locking-plate X rests inside the body of the shuttle under the bobbin B, over a stud, O, on which it works. The hooked ends are adapted to project alternately over the rectangular tubes of the shuttle and under the brackets D, outside of said tubes. The bobbin sets over the stud O, and is kept in position by a tension-regu'lating spring, E, and a key, F, the latterpassing through a slot, G, in the stud.

The letter H indicates two trip springs, which are secured to the batten in such position as to alternately shift the locking-plate,

. as more fully hereinafter specified.

hooks on the double locking-plate. \Vhen the shuttle starts to enter the warp from either side, the arm Y of the locking-plate comes in contact with the trip-spring H, the effect of which is to carry the locking-plate out of engagement with the spring-catches on the carriers on which the shuttle is then supported, and cause the hook of said plate at that end of the shuttle that is to engage with the opposite carrier to be closed over the slot in the shuttle in such manner that when the shuttle meets the opposite carrier the springpawl of the latter'will be forced downward under the hook, and after having passed it will spring back to normal position to seize the shuttle. Vhen being carried forward by one of the carriers, the shuttle is retained thereon by its own weight.

Having thus described my invention, what I claim, and desire to secure to secure by Letters Patent, is

1. The combination, with the guides B, power-shaft E, and stationary rack-bars H, of a reciprocating lay, a crank upon the main shaft, pitman connecting said crank with the lay and giving to the samea differential speed, oscillating segments mounted upon the lay, having arms I, the shuttle-carriers, and propelling-rods K, connecting said arms with the shuttle-carrier, as set forth. I

2. The combination of the lay, the lay-supporting bars, and the loom-frame, with the segmental gears provided with arms, the studs on which said segmental gears are pivoted, the propelling-rods secured to the gear-arms and carriers, the carriers, the rack-bar whereby the parts are operated by the motion of the lay, and means for operating said lay, suhstantially as specified.

3. The combination of the carriers provided with longitudinal slots, as shown, and having spring hook-catches secured in said slots, with the shuttle having square receivin g-tubes, the lay, lay-supporting bars, the loom-frame, the segmental. gears and connections, and means, as described, for operating the lay, substantially as specified.

4. The combination of the shuttlebody with the locking-plate, the fixed stud or bobbin-pin, the bobbin, tension-spring, and key for holding the bobbin on the bobbin-pin, all

arranged to operate substantially as specified. 5. The combination of the shuttle-body with the locking-plate provided with a projection having an eye for the passage of the wire from the bobbin, the fixed stud, the bobbin, tension-spring and key, and the contining-spring, all arranged to operate substantially as specified.

This specification signed and witnessed this 19th day of September, 1882.

. I THOMAS PATTERSON. l/Vitnessesz L. P. HOLLENBEOK, W. J. HOLLENBEOK.
