BOXLOOM.'

Specification of Letters Patent.

Patented Aug. 11, 1908.

Application filed June 6, 1907. Serial No. 377,558.

To all whom it may concern:

Be it known that I, BALTHASAR FUHRER, a citizen of the United States, and a resident of Scranton, in the county of Lackawanna and State of Pennsylvania, have invented a new and Improved Box-Loom, of which the following is a full, clear, and exact description.

he invention relates to weaving and its object is to provide a new and improved box loom in which the picker mechanism receives an auxiliary shifting motion besides the regular picking motion, so as to cause the picker to push the shuttle back into proper position in the shuttle box, in case such shuttle has passed outward beyond the shuttle box and rendered the subsequent raising and lowering of the shuttle box difficult and dangerous to the mechanism of the loom.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of the right hand side of the loom, parts being section; Fig. 2 is a like view of the same, showing the parts in a different position; .Fig. 3 is a sectional plan view of the same on the line 33 of Fig. 1, and Fig. 4 is a sectional side elevation of the cam and its mounting, the section being on the line 4-4 of Fig. 3.

In box looms as now generally used, it sometimes happens that a shuttle after being sent through the open shed passes somewhat beyond its proper position in the shuttle box, and hence when a subsequent raising or lowering of the shuttle box takes place then this miscarried shuttle interferes with this movement and is itself liable to be broken or do damage to adjacent parts of the loom. In order to avoid this, the miscarried shuttle is returned to the proper position in the shuttle box by the mechanism presently to be described in detail, and shown connected with the picker stick to give an auxiliary movement to the picker stick besides the regular motion required for sending a shuttle from one side of the loom to the other side through the open shed.

The box loom, of any a proved construction, is mounted on the 00m frame A, on which reciprocates the lay B, carrying on one or both sides of the loom a shuttle box C containing a number of shuttles D located one above the other, and supporting bobbins I filled with different colored yarn. Either ofthe shuttles D can be brought into active position, that is,-into alinement with the shuttle race E, on raising or lowering the shuttle box 0 correspondingly by the action of. the jacquard controlling the raising and lowering mechanism F of the shuttle box C. N ow the shuttle in active position at the time is sent through the open shed by the picker G of the picker mechanism, the said picker G being mounted to slide on the outer end of the lay B and being connected with the picker stick G, to which is attached one end of the picker stick strap G connected with the usual mechanism for imparting a swinging motion to the picker stick G, for the lat ter to actuate the picker G with a view to send the shuttle D off the shuttle race and through the open shed in the usual manner. The return motion of the picker stick G is accomplished by the strap G connected with a spring, not shown.

e loom mechanism so far described is of the usual construction and forms no part of my improvement, it being understood that the lay B serves to beat up the weft thread carried through the open shed by a shuttle sent through the open shed by the picker G at the time the lay B is in a rearmost position.

On the picker stick G is secured a bracket H in which is j ournaled a roller H traveling on the peripheral face of a cam I having an elongated slot I engaged by a bolt J extending through an elongated slot K in a bracket K, to allow of adjusting the cam I and to securely fasten the same in place on the bracket K after the desired adjustment is made. The bracket K is bolted or otherwise fastened to a bracket A of the loom frame A, as plainly illustrated in the drawings. Now when the lay reciprocates and with it the shuttle box O, the picker G and the picker stick G, then the roller H successively assumes the positions 1, 2 and 3 and 3, 2, 1, marked in Fig. 3; that is, when the lay B is in the rearmost position the roller H is in the position 1, and the picker mechanism when now actuated sends the shuttle through the open shed in the usual manner, and when the lay swings forward, the roller H in traveling on the cam I slightly swings the picker stick G inwardly, and

action of the roller H when the lay reaches the beating in position the roller H is in the position 3, and after the beating in has taken place and the lay returns, then the position of the shuttle box 0 is changed if another colored thread is called for, and during the return movement of the lay the roller H assumes successively the positions 2 and 1. Now when a shuttle comes through the open shed and passes beyond the shuttle box C at the time the lay is starting on the forward stroke, then the inward swinging given to the picker stick G by the traveling on the cam I, causes an inward shifting of the picker G, whereby the miscarried shuttle is pushed inward, back into the proper position in the shuttle box C, after which the picker G returns to its outermost dormant position during the time the roller H travels from the position 2 to the position 3, so that the shuttle box 0 can subsequently be readily raised or lowered without danger of injury to the shuttle or other parts of the loom.

It is understood that the roller His always held in firm contact with the peripheral surface of the cam I, by the action of the spring connected with the strap G except during the time that the strap G imparts the usual picking motion to the picker stick G.

7 From the foregoing it will be seen that an auxiliary shifting motion is given to the icker G, for pushing a miscarried shuttle D backo into proper position in the shuttle When the lay B starts to go forward, the l picker G moves almost in contact with the shuttle point the action of the roller H traveling on the cam I, so that when the I picker mechanism is actuated in the usual manner, for sending the shuttle across the open shed, then the picker G by being close to the point of the shuttle D, properly proels the latter without danger of injury to the shuttle point or face of the picker coming in contact with the shuttle point.

From the foregoing it will be seen that the device can be readily applied to looms as heretofore constructed, as it is only necessary to add the roller H, the cam I and the brackets H and K to the loom, in the manner above described and illustrated in the drawings.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

In a box loom, the combination of a lay, a shuttle box slidable on the lay, a picker stick, a picker in connection with the stick, means for operating the picker stick to move the shuttle from the box, and a roller and cam mechanism connected with the picker stick for imparting an auxiliary motion thereto for shifting a displaced shuttle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
