STOP-MOTION FOR LOOMS.

Specification of Letters Patent.

Application filed July 1. 1920. Serial No. 393,237.

To all whomt't may concern:

Be it known that I, SOLQZ-JON KAirnLoAR, a citizen of the Republic of Poland, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Stop- Motions for Looms, of which the following is a specification. I

This invention relates to means for stopping a loom of the box-loom type whenever it inadvertently happens that when a shuttle is in position to be shot across the lay or batten another shuttle is in a box which is alined with the lay, so that a smash. would occur if the first shuttle were thrown. The

object of the invention is to provide a means of this lrind which, while efficient and reliable in operation, shall be simple in construction.

in the accompanying drawing,

Figure l is a front elevation of the batten structure and the parts of my mechanism which are carried thereby;

Fig. 2 is a plan view showing the batten structure, the breast-beam-including part of the loom frame, and my mechanism;

Figs. 3 and 4e are sectional views on the line 3-3, Fig. 2, showing the parts in the positions they occupy before and after the knocking-01f action has occurred; and

Fig. 5 is a sectional view on the line 5-5,

Fig. 1.

On the loom-frame a. is the breast-beam Z2, and suitably arranged to reciprocate toward and from the breast-beam is the batten c. d indicates asingle shuttle box at one end of the batten and e a vertical series of shuttle boxes moved up and down at the other end of the batten by any suitable means, not shown. Each shuttle box has a binder c which is movable outwardly by the shuttle, in the usual way, when the same enters the box, such binder being in the present instance a part of my means for stopping the loom and so preventing a smash.

In the frame a underthe breast-beam is journaled the usual knock-off shaftf, the same being provided in the present instance with a collar 9 having a downwardly projecting toe h.

A plate 2' is secured to the front of the batten opposite the collar 9 and is formed with a vertical dovetailed groove j. This plate has a forwardly rojecting hookshaped arm is in which 1S, fulcrumed the dagger Z arranged when the batten moves forward to miss said toe or impinge against the same, according as the dagger stands do pressed or elevated. In the groove 7' slides a block m which is normally impelled downwardly by gravity (assisted by a spring a, if desired). This block m has a depending stem m which is pivotally connected to the rear end of the dagger. The block has a cross cut or horizontal groove o'in its front face.

The block is normally held elevated, thus holding the free end of the dagger depressed, so as to miss the toe 7b of the collar g, by the protector rods 39 alined with each other and journaled horizontally in brackets Q attached to the batten. The inner end of each rod is bent to form a crank 1' which is engaged in the groove 0 and is normally held therein by a spring t which is coiled about the rod and is secured at one end to a collar u, adustably secured on the rod, and at the other end to the adjoining bracket 9. The outer end of the protector rod which adjoins the series of shuttle boxes 6 has an arm 4) which bears against the shuttle binders e of those boxes; the outer end of the other protector rod is formed as a crank w and bears upon the forwardly projecting arm of a lever to, fulcrumed in the batten and having an upwardly projecting arm to bear against the binder e for the adjoining or single shuttle box (Z.

The operation is as follows: So long there is only one shuttle in the box (Z and one of the boxes 6 alined with the batten the means to actuate the knock-off shaft (such means including the slide m) will be held in the position shown in Fig. 1 or Fig. 3, 'i. 6., so that the point of the dagger will be depressed and consequently miss the too it, this is because, although the shuttle present has caused the corresponding protector rod to rock to the position shown in Fig. 4c, since there is no shuttle in the box alined with and at the other end of the batten, the other protector rod remains in looking engagement with the groove 0 of the slide, holding it elevated. But if both boxes alined with the batten contain shuttles, then both protector rods will have been rocked and so caused to release the slide, so that it falls and allows the dagger to assume the position shown in Fig. 4, and then on the next beating-up movement of the batten the dagger will Patented Nov. 9, 1920.-

strike the toe h and so rock the knock-off shaft. V

The daggerdmpact face of toek is preferably arranged at such an angle that on the dagger impinging thereagainst and rocking the knock-off shaft to the dotted line position, said face Will assume an inclined position (dotted lines, Fig. 4) and so serve as a cam thereupon to depress the point of the dagger and cause the latter to elevate the slide, so that upon removal of one of the two shuttles the corresponding protector rodavill again interlock with the slide and hold it and the dagger in the idle position. I

Having thus fully described my invention,

7 What I claim as neWand desire to secure by Letters Patent is p I 1. In combination, With the loom fraiiie, knock-off means movable therein, and ten structure movable in said frame and having shuttle-boxes at the ends thereof, means to actuate the knock-off means including a slide and movable in the batten structure from a position to clear to a position to en'- 25 gage the knock-off means and normally impelled to the latter position, and separate means, disconnectively coupled with the slide, to hold the second means in the former position, each of said separate means being respectively actuable by a boxed shuttle to release the slide. i

2. 111 combinatiOm-with the looni firame, knockofi' means movable therein, and a batten structure movable in said frame and having shuttle-boxes at the ends thereof, means to actuate the knock-oil means including a slide movable vertically in the batten structure from a position 'to clear to a position to engage the knock-"0E means and normally impelled to the'latter position, and separate means to hold'th'e second ineansin the former position, each of said separate means includ ing a protector rod journaled in tliebatten and 'actuahle by one of two boxed shuttles alined with the batten and having a crank movable into and out of interlocking err gagement with the slide.

In testimony whereof I aflix mysignature.
