IMPROVEMENT IN LOOMS FOR WEAVIN-G CLOVTH WITH SWELLS 0R GORI-IS. 'l

Speciti cation forming part of Letters Patent No. 57,177, dated August 14, 1866.

- To all whom 'it may concern.-

Take-Up Motion of Looms for Weaving Cloth with Swells `or Gores, and I do hereby de,

clare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure lV is a plan, and Fig. 2 a longitudinal vertical section. I

The same letters indicate like parts in both iigures. i

In weavin g cloth with swells or gores-such, for instance, as required for making corsetsthe weaving-in takes place at times across the entire width, and at other times across eertain portions otl the width, depending upon the extent, form, and location of the intended gores or swells. To accomplish this result in a power-loom the mechanism must operate on the woven cloth to take it up as woven on so much of the width as is being woven at anyone time. When the weaving is taking place across the whole width the takeup mechanism must operate upon the whole width of the cloth to take it, and if the weaving is taking place on a quarter ofthe width,- for instance, the take-up must operate on a corresponding part of the width and its operation be suspended on the other parts of the width.

In power-looms for this kind of Weaving the parts of the width on which the weaving is to take place along the length is determined by the jacquard, and that mechanism also determines the corresponding part of the takeup which is to be active. There has been heretofore invented for this purpose what is denominated a sectional take-up-that is,

a series of rollers mounted side by side on an arbor with a corresponding series of pressurerollers, and each section of the take-up roller was actuated by a ratchet on a lever, all these ratchet-levers being connected with the jac-A quard by cords, and the sole duty of the jacquard was to select the levers of the sections required at any one operation of the loom to be operated. and v hold them in operation to be acted upon by the lay of the loom to make such rollers take up the corresponding sections of theloom.

My invention is of an improvementI on such sectional take-up mechanism. by which I avoid the necessitycf using a series of take'up rollers. I use the usual `take-up roller.,` consisting ers from the take-up roller, and thus liberate the cloth in the parts of the width where the weaving is suspended.

In the accompanying drawings, a represents a frame which is to be secured to theinside of the breast-beam of a loom. A takeup roller, b, of the usual or any suitable construction, is mounted in the said frame, and the shaft of this roller is provided with a ratchet-wheel, c, or other gearing, to be operated by a ratchet movement, as is usual iu power-looms. y

A series ot right-angle levers, d, is mounted on a fulcrum-rod, c, and each ofthe said levers carries a roller, f, which is pressed upon the periphery of the take-up roller b by the tension of the spring g, so as to gripe the cloth with suflicient force to insure the taking up of the cloth by the motion of the take-up roller.

.A series of vertical levers, h., are mounted on a fulcrum-rod, t', so that their' upper arms can act on the levers d when required to lift the pressurerollersf to liberate the cloth whenever the take-up operation is to be suspended;

and to the lower arms ot' these levers h are jointed a series of rods, j, held up by cords 7c,

When the jacquard lifts any of the rods j to the position represented by dotted lines the bar m on the lay will clear them, so that the corresponding rollers j' will make the required pressure on the cloth and cause the take-up roller to take up corresponding portions of theV Width of tbe cloth.; but such of the rods as are not lifted by the jacquard will be struck by the bar 'in on the forward beat of the lay, thereby lifting the corresponding rollers j', which will cause the take-up operation to be suspended on corresponding parts o f the Width of the cloth. In this Way it Will be seen that the cloth can be taken up ou any part of its Width, as may be determined by the mounting of the jacquard, Without the necessity of a sectional take-up roller.

What'I claim as my invention, and desire
