INDIVIDUAL TAKE-UP MECHANISM FOR NARROW-WARE LOOIVIS.

Specification of Letters Patent.

Patented Jan. 14:, 1908.

Application filed May 31,1905. Serial No. 262.986.

To all 10h 0m it may concern Be it known that LALnEirr ll. S'rEEiE, of l/Vorcester, in the county of Worcester and State of Massachusetts, have invented certain new and, useful Improvements in Individual Take-Up Mechanism for Narrow- Ware Looms, of which the following is a specification.

Figure 1 represents a front view of so much of a narrow ware loom as is necessary to illustrae my invention. l ig. 2 is a vertical, transverse section there. through, taken on line X, Fig. l, looking in the direction of arrow X. Fig. 3 is a transverse section through the take-up shaft with the detachable handwheel of one of the take-up pullevs removed,

showing a side view of said pulley and its spring-pawl mechanism, hereinafter described. Fig. 4 is a similar transverse section looking in the opposite direction, through the rim and hub of the take-up pulley showing the opposite side view of said. spring-pawl mechanism, and Fig. 5 is a plan of said mechanism and the internal hub which supports the same, also hereinafter described.

My invention relates to what are commonly known as narrow ware looms, for weaving narrow fabrics, such as tape, sus pender material and similar narrow goods.

The object thereof, is to provide. mechanism connected with the take-up shaft of this class of looms, whereby each web of fabric may be independently adjusted without interfering with any of the other webs on said loom, and said invention consists in combining with the take-up shaft, a series of loose pulleys, each provided upon the inner surface of its rim with longitudinal corrugations or teeth, a fixed hub for each pulley fitted and fastened on said take-up shaft; spring-pawls mounted on each fixed hub and engaging with the internal corrugations on the. pulleys and a hand-wheel for disengaging said spring pawls from said corrugations on the pulleys, as hereinafter more fully set forth.

To enable others to better understand the nature and purpose of my said invention, I. will now proceed to describe it more in detail.

Referring to the drawings A represents part of the loom frame, and B part of the usual take-up shaft, which extends longitudinally through the front side of the machine. The parts marked C are the individual takel l l l l i 1 up pulleys which are mounted on said takeup shaft about two inches apart, and the parts i) are the knee-rolls mounted in the outer ends of the swinging arms E, pivoted at their opposite ends at 1G, to a fixed bearing l on cross beam A, -ach of said kneerolls being each adapted to rest on its respective web (1 over the take-up pullem, to produce the required friction on said web during the weaving operation.

The take-up pulleys are fitted loose on shaft B and are each held in position longitudinally thereon by the outer collar (1 and internal hub ll, both of which are secured to said shaft; upon each internal hub ll, are mounted two pawls (1 (I, at opposite sides of the shaft, each pawl being pivoted at 1), provided with a holding spring c and their outer ends adapted to engage with the longitudinallv corrugated or toothed, inner surface l" of its respective pulley (l, as is best shown in Figs. 2%, l and 5 of the drawings. The normal positions of the pawls are in engagement with the aforesaid corrugated surfaces of pulleys (l, being thus held in engagement by said springs c, one end of which is attached to hub ll and the other end to the pawl. The inner ends of the pawls (z, (I. are provided with extensions or made cam-shaped to engage with the hub ll, and form a stop to prevent the pawls from being drawn over too far by the spring c.

oinbiued with each take-up pulley (l is a detachable hand-wheel l, on the hub ll. The littlltl\."ll((l l has thereon two projections or pins l, 1. adapted to come in contact. with two levers c, c secured upon the pivot pins 1), I) of tho pawls (1..

ln Fig. 3 of the drawings, the positions of said projections on the detachable handwheel are shown by dotted lines against the pawl pivot levers c, c.

The pawls (I, (I. being normally in. contact with the. internal, corrugated surfaccsof the take-up pulleys, it isobvious that said. pulleys are thereby normally held from turning in. one direction, and that direction is the direction opposite to the draft of the web G being fed through. So long as no trouble occurs in the weaving, the parts remain in. said locked, normal positions, but if for any reason it is desirable to loosen the. draft upon one of the webs, to adjust or correct the same in. any way, its hand-wheel is turned loosely mounted to disengage the pawls a, a, from said corrugated surface of the tal eup pulley by forcing its inner projections I I against the pawl pivot levers as previously described, said operation freeing said take-up pulley so that it may be turned backwards a partial revolution and thus relieve the draft upon the web so that it may be drawn longitudinally and the required repair or correction made Without stopping the loom, or interfering in any way whatever with the weaving of the other webs on said loom. It is preferable to employ a stop for controlling the rotation of the detachable hand-wheel I within proper limits to prevent damage to the pawl mechanism by turning said hand-wheel too far in the wrong direction, but I do not limit myself thereto as it is not an essential feature. In this instance, I have shown said result as being accomplished by providing a projection I on the inner surface of the hand-wheel which strikes against shoulders I I on the hub H when said handwheel is turned in either direction. The take-up pulleys C are each provided with the fixed hand-wheel C formed upon or secured thereto in the usual way, and by means of which said pulleys are turned in either direction, as desired.

It will be understood that the details of varied if desired.

Having thus described my invention, and desire to secure by 1 construction of my improvements may be What I claim as new Letters Patent is:

A take-up mechanism for narrow-Ware looms, comprising a take-up shaft, a loose pulley on said shaft, said pulley having teeth or corrugations upon its inner surface, a fixed ti ALBERT H. STEELE. l
