LO OM.

SPECIFICATIONforming part of Letters Patent No. 595,417, dated December 14, 1897.

I I Application filed July 16, 1897. Serial No. 644,752. (No model.)

To all whom it may concern-.

Be it known that I, PETER O. STADLER, a

, citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Looms, of which the following is a specification.

My invention relates to looms in which the shuttles are operated by means of a shuttle rack-bar, and the object of my improvement is -to' prevent the derangement of the shuttles by out of place. These improper movements of the shuttle rack-bar cause the relative posi- I tions of the marionette-hooks to become so changed that they will be operated out of their proper order, resulting in a misweave and necessitating the stopping of the loom. The object of my improvement is to avoid this difficulty by steadying and controlling the action of the shuttle rack-bar and preventing its moving in its groove except as it is pulled by its actuating-cords, thereby permitting'a high rate of speed without disturbing the normal action of the loom. This end I accomplish by means of the devices shown in the accompanying drawings, which illustrate my improvement as applied to a loom adapted to weave narrow goods, as ribbons, in which the shuttle rack-bar is operated by means of marionette-hooks and the connecting parts usual in that form of loom. r

In the accompanying drawings, Figure 1 is a front elevation of a part of a loom with my improvement attached thereto,showin g a portion of the batten, partly in section, and the marionette-hooks and their operating-pin and the connections with the shuttle rack-bar. Fig. 2 is a plan view of the same, the marionette-harness being omitted for the sake of clearness. In this figure the top of the batten is removed, exposing to View the shuttle rack- In looms not provided. with such a 0011- bar. Fig. 3 is a section, on an enlarged scale,

on the line 3 3 of Fig. 2. Fig. 4 is an enlarged plan view of the sliding plate, upon which is mounted one of the antifriction guide-rollers, as hereinafter described.

Similar letters of reference refer to simila parts.

A is the batten, provided with a groove or channel, in which the shuttle rack-bar R is caused to reciprocate by means of the cords G O, which are attached at one end to the piece B,secured to the side of the shuttle rackbar R, and at the other end to the marionettesticks H H, which latter are operated by the pin W on the driving-rod L, engaging with the hooks h h in the customary manner.

D is the raceway of the shuttle, which latter is operated by means of the pinion E, in engagement with the rack-bar R in the usual way.

P is the pulley under which pass the cords C O. I do not claim anything new in the construction or arrangement of the foregoing parts, as they are in common use.

F is an antifriction guide-roller mounted upon the batten A on one side of the rackbar R and in contact therewith. Fis a similar roller mounted upon the sliding plate G on the opposite side of said rack-bar R. In the drawings I have shown the centers of the rollers F F as being in the same vertical plane with the axis of the pulley P; but they need not be so necessarily. The sliding plate G is provided with slots a a and is held in position by the guide-screw headst IE, but so as to permit the plate being moved toward or away from the rack-bar R, the extent of such movement being regulated by the length of the slots (1 a. The plate G is also providedwith the pin K, against which presses the free end of the spring S, thereby forcing the plate G inward and bringing the roller E into contact with the side of the rackbar R. The other end of said spring S is made fast to the batten at O, and the degree of pressure of the spring S upon the pin'K is regulated by the screw N. The antifriction guide-rollers F F revolve With each movement of the rack-bar R. .It will thus be seen that the shuttle rack-bar R may be held as tightly as desired between the two antifriction guide-rollers F F and its movement prevented, exeept as the rack-bar is pulled to and fro by the cords C O. The loom may be run at a high speed without danger of the rackbar running ahead of the proper action of the loom or rebounding when it strikes the end of the groove, and the derangement of the working of the loom consequent thereon will thus be avoided.

It is evident that the form, arrangement, and location of the parts above described may be changed and other well known devices may be substituted for the several parts without altering the principle of my improvement.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. In a loom, the combination of the batten, the shuttle rack-bar and means for operating the latter, with antifrietion guide devices placed upon opposite sides of and in contact with said rack-bar between which antifrietion guide devices the rack-bar is adapted to reciprocate, and means for regulating the degree of pressure of said antifriction guide devices upon said rack-bar, substantially as shown and described. I

2. I11 a loom, the combination of the batten, the shuttle rack-bar and means for operating thelatter,withastationaryantifriction guideroller placed upon the batten on one side of the rack-bar and in contact therewith, and a similar movable roller on the opposite side of said rack-bar and means for pressing said last-mentioned roller against the rack-bar, substantially as shown and described.

In a loom, the combination of the batten, the shuttle rack-bar and means for operating the latter, with a stationary antifriction guideroller placed on the batten on one side of the rack-bar and in contact therewith, a sliding plate secured to the batten on the opposite side of said rack-bar, an antifriction guideroller mounted on said plate, and means for moving said sliding plate toward said rackbar, substantially as shown and described.

4. In a loom the combination of the batten A, the shuttle rack-bar R and means for 0peratin g the latter, the antifriction guide-rollers F, F, the sliding plate G on which is mounted the roller F, and means for regulating the degree of pressure between said rollers and the rack bar, substantially as shown and described.

5. The combination of the following elements in a loom, viz., the batten A, the shuttle rack-bar R and means for operating the latter, the stationary antifriction guide-roller F, the antifriction guide-roller F mounted on the sliding plate G, the said sliding plate G, and the spring S, which latter is adapted to move said sliding plate toward the rack-bar, substantially as shown and described.
