Specification of Letters Patent.

Patented Feb. 22, 1910.

Application filed October 24, 1908. Serial No. 459,298.

To all whom it may concern:

Be it known that I, WILLIAM HVARRIS, a

subject of the King of England, residing in Paterson, lassaic county, New Jersey, have invented a certain new and useful Improvement in Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will euable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to characters of reference marked thereon, which forms a part of this specification. This invention relates to looms of the type,

depositing the finished goods in boxes under the loom, but to make the delivery or'warp spools rotate the spools for the finished goods and thus effect the necessary take-up, whereby to avoid the loss of labor and time now required in occasionally replenishing the'exhausted slack by releasing the warp spools and paying out more warp.

Another object is to provide in a simple way for controlling the finished goods so that it will not only be wound in succeeding regular con-volutions on the several spools but so that the extent of movement of the.

weights may be as limited as desired or nec essary. In the accompanying drawing, Figure 1 is a vertical sectional view of the improved loom; Fig. 2 a similar view, on a larger scale, of the upperrear part of the loom; Fig. 3 a rear View of what is seen in Fig. 2, the spools being omitted; Figs. 4: and 5 side and end views of one form of spool; and, Fig. 6 a side view of another formof spool.

a is the loom-frame; b the breast-beam carrying glass-bars c; d the suspended lay or batten structure; e. the harness and f the usual beam, supporting glass-bars g.

The warps it extend from the supply spools 2' over rollers journaled in a superstructure In on .the frame a, suspended loops 'Z being formed in the warps between said rollers and sustaining the tension weights m; from said rollers the warps extend under glass-bars g, thence forward through the harness and over the batten. The finished goods 02, extend over the glass-bars 0, around the sand-rollers 0, over the pressure-rollers 10, back under a guide-bar g and up to the spools 7; An inclined frame 8 is arranged at the back upper-part of frame a, the upper and lower beams 25 of which are connected by oblique parallel strips a from which project skewers e, on these skewers are arranged spools i and r, interlocked in the manner to be described so that the rotationof the spools 6 under the pull of warps rotates the spools r in the same direction, the woven goods being wound on spools -r as the warps are unwound from spools z.

Figs. 4, 5 and 6 show how the spoolsmay be interlocked: In Figs. 4 and 5, each spool -has segmental projections w formed diametrically opposite each other one atone end and the other at the other end of the spool; when two such spools are placed end to end on a skewer they will be interlocked for rotation together and the interlocking action may be augmented by forming the acting side of each projection withthe undercut In Fig.6, insteadof segmental projections, a headed device 3 such as a screw, .is driven into one end of the spool and a staple a orthe like into the other end thereof, each screw and staple interlocking when two spools are brought face to face on the same axis. any means for rotating the spools r from the spools i is comprehended within the invention, however.

the spools r I preferably employ the following mechanism: A series of light slats l is kept in reserve on lower beam t of frame 8, and as a complete coil or pile 2 of finished goods forms on each spool r and the goods has been shifted to start a fresh coil, one

rear .face of the beam or the slat previously so placed, being supported by the spikes .3.

Spacing strips may be laid across each horizontal row of skewers, as at at, to keep the inner face of the end of each spool r in the plane of the rear faces of beams 15-- the proper position of these spools for receiving the first coils.

By my arrangement I not only avoid the It will be understood that To guide the woven goods properly onto slat is removed and set flatwise againstthe undesirable use of hbxes for receiving the finished goods and the necessity of frequently paying out more warp as the slack is taken u in the weaving but can pick back an effect other operations attending the weaving much more readily and with less loss of time than is possible in the present arrangement of loomsof this character. The weights we maintain the necessary tension, while the loo s 1 afiord com pensation under all con itions for constantly changing differences in diameter as between the spools i and 7.

When the loom is started, the warp-spools bein full and the oods spools empty, the weiglits fall gradua y as the weaving proceeds, because on each revolution of the member comprising the interlocked spools 2' Y and r, a greater length of warp is paid out than length of goods is taken up. This continues, though at a diminished rate as the oods spool augments in diameter, until the iamcters of the spools are equal, whereupon, the weights now rise gradually, at a constantly increasing rate. When a pile or coil of goods .has reached a predeter mined height the goods is shifted to start a fresh pile. In this way, the extent of movement of the weights is controlled to suit the conditions, when otherwise it might be so considerable as to require "frequent attention to insure the weights exercising the proper tension action on the band or web-comprising the warp and finished goods, it being obvious that whenever the goods are shi ted to start fresh piles or coils the Weights begin to run down again.

I do not w laim herein the-means for guiding the finished goods (said means herein ta in specifically the form of thespikes 3 and s ate 2), that being reserved for my copending application, Serial No. 485891, filed March 26th, 1909.

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

1. In a loom, the combination '-of the frame, means for guiding the we and finished goods, a rotary warp-supp y device and a rotary receiving device for the finished goods, the latter bein driven rota-' tivelyfrom the former, where y to wind the" goods v on the I receiving device as the warp 1's unwound from the supply device, sub stantially as described.

2. In a loom, the combination of" the frame, means for guiding the warp and fin ished goods, a rotary warp-supply device, a

rotary receiving device for the finished goods, the latter being driven rotatively from the former, whereby to vwind the goods on the receiving device as the warp .is unwound from the supply device, and means for maintainand interlocked for rotation together, sub-' stantially as described.

l. In a loom, the combination of the frame comprising an axial support, means for guiding the warp and finished goods, a rotary warpsupply device and a rotary "recelving device for the finished goods arranged in axial alinementon said support and interlocked for rotation togetheiyand means for maintaining a tension onv the warp and finlshed goods, substantially as described.

5. In a loom, the combination the frame, means for guiding the warp and fin ished goods, and a rotary member comprising a warp-delivery portionrand a goodsre ceiving portion substantially axially alined with each other and mutually retatable in one direction, substantially as described.

In testimony, that I claim the foregoing,

I have hereunto set my hand this 23rd day of October, 1908.
