WILLIAM HARRIS, OF PATERSON, NEW JERSEY.

LOOM.

Application filed March 26, 1909.

Specification of Letters Patent.

Patented Mar. 12, 1912.

Serial No. 485,891.

T 0 all whom it may concern:

Be it known that I, VILL'IAM Harms, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Looms, of which the following is a specification.

This invention relates to looms of the type, usually of the narrow-ware class, in which the necessary tension on the warps is maintained by weights suspended in the warps, the warp-supply spools normally being held against rotation and only being al lowed to rotate as the slack represented by said loops becomes exhausted.

In my application for U. S. Letters Patent filed October 24:, 1908, Serial No. 459,298, I disclose an improvement in such looms in which the finished goods, instead of being deposited in boxes or the like under the loom, are caused to be wound on suitable receiving devices rotated from the warp-supply spools or the like. In that case the warp-supply and goods-receiving devices were axially alined with each other and rotated in the same direction. In the present instance, they are not axially alined but are arranged substantially side by side and preferably obliquely with regard to the paths in which the warp and finished goods extend from and to them, respectively, and they rotate in opposite directions, each controlling the other, however, the same as before. Thus, I attain the advantage, not heretofore possible, that the tangent formed by the goods and that formed by the warps are at relatively opposite sides of the goods-receiving and warp-supply devices, respectively, so that when two or more pairs of spools or the like (each comprising a warpsupply and a goods-receiving device) are arranged in a line side by side the warps and goods will clear all the spools and avoid the undesirable results attending their wiping against them.

The foregoing indicates one of the objects of the present invention; a further object is to improve the means for controlling the laying on of the finished goods on their receiving devices.

In the accompanying drawing, Figure 1 is a vertical sectional view of the improved loom; Fig. 2 is a similar view, on a larger scale, of the upper rear part of the loom; Fig. 3 is a rear view of what is seen in Fig. 2; Fig. l is an enlarged detail illustrating one way in which the warp-supply and goods-receiving devices are made to reciprocally control each other; Fig. 5 is a rear face view of one of the pinions shown in Fig. 4-; and, Fig. 6 illustrates a modification of what is shown in Fig. 4.

a is the loom frame, I) the breast beam carrying the glass bars 0; (Z the suspended lay or batten structure; 0 the harness; and f the usual beam supporting glass bars 9.

The warps 71. extend from the spools 2' (two or more of which may be alined with each other on the same axis and interlocked together by the means 2" shown in Fig. 4 or in any other way) over rollers j journaled in a supporting structure it on frame a, suspended loops Z being formed in the warps between the rollers and sustaining tension weights on; from said rollers the warps extend under the glass bars 9, thence forward through the harness and over the batten. The finished goods 12 extend over the glass bars 0. around the sand-rollers 0, over the pressure-rollers 7) back under a guide-bar q and up to the spools 1'.

It will be understood that any well-known mechanism (not shown) may be employed to cause the advancement of the warp and finished goods.

An inclined frame 3 is arranged at the back upper part of frame a, the upper and lower beams t of which are connected by oblique parallel strips u from which project skewers U and '0. On the skewers '1; and 'v are respectively arranged the spools 2' and r, interlocked in the manner to be described so that the rotation of the spools i under the pull of the warps rotates the spools r in the reverse direction, the woven goods being wound on spools r as the warps are unwound from spools 2'.

Figs 4, 5 and 6 show how the spools may be interlocked. In Figs. at and 5, a pinion w is freely journaled on each skewer o, and on the corresponding skewer o is journaled a pinion w, the two pinions meshing with each other. Each pinion may be held from displacement axially of its skewer by a cotter-pin m in the skewer. Each pinion, in Figs. 4 and 5, also carries one or more pins 3 adapted to be received by holes 2 in the spool i (or'r). This arrangement allows the spools to be removed without removing the pinions, and avoids specially adapting the spool for the purpose in hand further than by drilling the holes therein to receive the pins 00. In Fig. 6 oneof the spools, say 2', is shown with a pinion 1 permanently attached thereto by means of screws 2.

In view of the foregoing and referring particularly to Fig. 3, it will be observed that as the warp is delivered by each warpsupply device the goods will be taken up and wound on the corresponding goods-receiving device. At the same time, since the tangents formed by the goods and the warp are at the relatively opposite sides of the warp supply and goods-receiving devices, respectively, and since, further, the devices are arranged obliquely relatively to the path of movement of the warp and goods, the latter will clear all of the spools.

From the lower beam t of frame .9 project rearwardly the arms 3. These arms are adapted to support a warp guiding bar or slat 4 which has pegs 5 on its under side adapted to be received by the alined holes 6 in the arms 8. Thus, when, as explained in my previous application aforesaid, each pile or coil 7 of goods has reached a predetermined height and it becomes necessary to shift the goods and start a fresh pile on the receiving devices, the bar 4 is removed from its previous position and replaced with its pegs in holes nearer the ends of the arms 3 than formerly.

I wish it to be understood that my present invention comprehends any arrangement of the rotary warp-supply and goods-receiving devices wherein they mutually cooperate with each other and have their axes nonalined.

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