' ASSIGNORS TO CLAYTON AND BENTLEY OF GEORGIA.

BENTLEY, citizens of the United States, residing at" At1anta,- in the county of Fulton and State of Geor ia, have invented certain ments in Thin-Place Detectors for Looms;

new and useful mproveand we do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will. enable others skilled in the artflto which it appertains tomal e use the same.

Our invention relates to looms; and it'is more particularly maticallystopping the loom when the shuttle does not work or the fillin misses one or more picks and when a thin or imperfect lace is therefore produced within the fabric. The invention consists of the novel fea tures of construction and combination of parts, which will be hereinafter more described, and pointed out in the claims.

In the accompanying shown the preferred form of our invention.

In said drawings, Fi ure.1 is a erspective view of a portion ofthe loom, s owing our improved attachment thereon. 'Fig. 2 1S adetail view showing thevmeans for connecting the latch-bar to Fig. 3 is a perspective view showing the outer end of the deteotor-rod-and parts secured thereto.

Referring to the figures by numerals of reference, 1 is the breast-beam'of a oom, thesame having brackets 2 or the like thereon, in which is rotatably mousted a detectorrod '3. -An arm iextends Arom one end of this rod and is provided at i s free end with a bell-crank lever 4:, the lever being secured to the arm 4 4 The lower end of the bell-cram lever 4 is provided with a finger 5, which is adapted to contact with the fabric 6 in the loom at from the shuttle. Another arm 7 extends throu hand lboselg" enga es an arm 8, which exten s laterally'from a atchbar 9. This latch-bar is connected by a loop 10 with a knock-off lever 11 of the loom and is adapted to fall into on agement with the notch in the snake-hea hook 12, mounted in the weft-hammer 12.

It will be understood that as'the woven fabric is taken up the finger .5 will be suppivotally about two picks Specification of Letters Patent. Application filed July 17,1905. Serial to. 269,970."
