Loom.

This invention relates to improvements in looms and has for its primary object the provision of means for producing a slack in the warp threads at each operation of the loom harness and thus eliminate the stretching of thethreads and possible injury thereto as the threads are separated for the passage of the shuttle- More specifically stated, the invention provides means for automatically .moving the whip roller at each operation of the loom harness so as to produce the desired slack of the Warp threads as the latter are separated for the shuttle and to subsequently render the threads taut, the pivotal movement of the whip roller being governed by the operation of the lay.

With the above and other objects in view, the invention further includes the following novel features and details of construc tion, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is a fragmentary side View of a dobby loom with the invention applied, parts being diagrammatically illustrated.

Figure 2 is an enlarged fragmentary section on theline 22 of Figure 1. v

Figure 3 is a detail view of the roller arm pivot.

Figure 4 is a similar view of the pivot for adjustably connecting the whip roller arm with the connecting rod.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character indicates the frame of the loom, 11 the lay, 12 the lay leg and. 13 the loom harness, while the warp bar is indicated at 14. The warp threads 15 pass from the bar 14 over the,

whip roller and through the harness to the lay in the ordinary manner, except thatthe whip roller 16instead of being mounted in stationary bearings, is mounted in pivotally' movable bearings andthe latter are moved by the operation of the loom so as to produce a slack in the warp threads 15.

Where the bearings for the whip roller are stationary, operation of the loom harness in separating the warp threads for the passage of the shuttle, will stretch the said threads and frequently these threads are broken. The present invention overcomes this disadvantage by producing a slack in the threads as thelatter are separated so that they are relieved of strain. To accomplish this the Whip roller 16 is mounted in the upper ends 'of bearings 17, one of which is provided at each side of the frame 10. These arms are adjustably and pivotally mounted uponpivot pins 18, the frame 10 being provided with slots 19 to permit of longitudinal adjustment.

The lower ends of the arms 17 are longitudinally slottedas shown at 20 and passing through the slots of these arms are pivot bolts 21. The bolts 21 serve to pivotally and adjustably connect the lower ends of the arms 17 with rods 22, the latter being provided with loops 23 for this purpose. The

, pivotal connection between the arms 17 and of clamps 24, the latter carrying studs 25 upon which the 'rods 22 are pivotally mounted.

It will be apparent from the foregoing description and accompanying drawings that at each pivotal movement of the lay legs, the arms 17 will be simultaneously moved, movement of the lay and whip roller being relatively inward or toward one another so as to produce a slack in the warp threads.

The invention is susceptible of various changes in its form, proportions and minor details of constructionand the right is herein reserved to make-such changes as properly fall within the scopeof the appended claim. Y

Having described the invention what is claimed is j I I f A' loom comprising a slotted frame, a

swingable lay having legs pivotally con-j v nected at their lower ends to said frame,

arms remote from the lay and pivotally conof the arms and interposed directly between neeted at intermediate points in their lengths said legs and arm portions. t0 the slotted frame and having longitudi- In testimony whereof W0 affix our signa nally-slotted lower portions, a Whip roller tures. 1
