Application led AJuly Z0, 1894. Serial No. 518,151. (No model.) Patented in Switzerland December 28, 1893, No. 7,327; in France July 2, 1894, No. 239,344, and in England .Tuly 6,1894,No. 13,107.
To 1f/ZZ whom it may concer-n.-
Be it known that I, ISAE HEER, a citizen of Switzerland, residing at Zurich, Switzerland, have invented certain new and useful 5 Improvements in Looms, of which the following is a specification.
Patents have been granted for this invention in Switzerland, No. 7,327, dated December 2S, 1893; in France, No. 239,344, dated July 2, 1894, and in England, No. 13,107, dated July 6, 1894.
My invention relates to improvements in weaving-looms; and it consists of a toothed or rack-and-pinion-operated shuttle of rectangular cross -sectional shape, of shuttleboxes fitted to receive and to guide the said shuttles, and of a particular form of stopmotion -for stopping the loom when the shoot or weft thread has been broken or consumed.
The said improvements are specially designed for application to ribbon-looms.
Such being the nature and object of my said invention, the following is a complete description of same, reference being had to the accompanying drawings, in which- Figure 1 is a front elevation of a portion of the loom-batten and showing two shuttleboxes. Fig. 2 is a plan of Fig. 1. Fig. 3 is a cross-section online x, Fig. l. Fig. 4 is a front view of the shuttle. y Figs. 5 and 6 are plans of the same. Fig. 7 is a rear view.
The known toothed or rack-and-pinion-operated shuttles are guided by means of groove and feather in such a way that they cannot be removed from their boxes when their interior appliances have to be manipulated. rlhese appliances therefore must be manipulated without removing them from the boxes.
The toothed shuttle of rectangular or angularcross-sectional shape forming one part of my invention presents a cavity which is about three times larger than that presented by the common toothed shuttles, so that all the appliances necessary to a proper operation of the shuttle may be placed therein. According to the cross=sectional shape of the toothed shuttle the cells of the shuttle-boxes also are of rectangularcross-sectional shape. In order to manipulate the interior appliances 5o of the shuttle, namely, weft-tension device,
the stop-motion, dac. the shuttle has to be removed from the box, for Whichpurpose I provide the face of the box with a door, which serves when closed as a guide for the shuttle. These improvements considerably increase 5 5 the output of the loom.
` A, Figs. 1 to 7, is the toothed shuttle of angular cross sectional shape, and B are the shuttle-boxes, the cells b of which also have an angular cross-sectional shape, according 6o to the shuttle. The number of the cells arranged in one box may vary, conforming to the number of the shuttles to be guided.V Each box has toothed wheels on its rear side extending through the wall b to ,engage in the 6 5 toothed shuttles. In order to be enabled to put in and to take out the shuttle, every box is iitted with a small door D, consisting of the bars d d and pivoted on the rod E. This door is kept closed by means of the spring` 7o catch cl2. v The bars d guide the shuttles when the door is closed. These guide-bars extend transversely of the bars d', as shown in Figs.
1 and 3.
The shuttle placed in the box is not visible 75 during the act of weaving, so that the Weaver cannot become aware of the rupture or of the consumption of the weft. In consequence thereof it is absolutely necessary that the shuttles be provided with a stop-motion which 8o automatically stops the loom when the weft is broken or consumed.
The stop-motion placed in the cavity of the shuttle and forming part of my inventionconsists of two levers F F, Figs. 4, 5, and 6, con- 85 nected with each other by means of the link f and movable in horizontal direction. These levers are turned inwardly by the tension of the weft S, and when the latter has been broken or consumed turned outwardly by 9o the spring G.. In the first event the ends of the levers F F are kept in the cavity of the shuttle A. (See Fig. 5.) In the latter event these ends project out of the shuttle. (See Fig. 6.) The lever F is provided with an 95 eye-screw f', through which passes the weftthread S, thus enabling an action of the wefttension upon the levers F F to hold the levers retracted.
In order that the levers F F' may effect the roo stopping of the loom when the weft-thread S has been broken or consumed, a vertical shaft H, Figs. l, 2, and 3, provided with fliers h, is placed at the face of every box B in such a 4 manner that the fliers h comev into the reach of the levers F F. On the lower end of the shaft H is fixed the lever I, Fig. 3, the crankpin of which engages in a slot of the arm e, fixed to the rod E. At the moment when a shuttle enters a box from the right hand to the left hand the lever F acts on a flier h, supposing that the weft-thread has been broken or consumed, and at the moment when a shuttle enters a box from the left hand to the right hand the lever F acts on a flier h. In both events the shaft H is turned and the rod E axially shifted. By means of the grooved disk e and the rod c2 the rod E acts on a lever e3, having1 a V-shaped end. This end, turned to the right or to the left hand, presses the upper arm of the hook-lever K forwardly, (see Fig. 2,) so that the hook of this lever releases the stop-lever L, which follows the pull of the spring Z, and by means of suitable known appliances shifts the fork M to the running-pulley, thereby stopping the loom.
The oscillating shaft H forms an essential portion of my invention. The rod E and the other organs connected therewith, however, are not essential and may be replaced by other suitable appliances.
The levers are under tension of the spring O acting on one of them and the weft-thread engages the eye N on the lever F.
Having now particularly described and ascertained the nature and object of the said invention and in what manner the same is to beemployed, I declare that what I claim is I. In combination, the shuttle, the pair of stop-levers pivotally carried thereby, one of said levers having an eye for the thread, a spring connected with said lever and a connection from this lever to the other lever of the pair whereby the tension of the spring and weft applied to one lever will be transmitted to the other, said connection consisting of a link, substantially as described.
2. In combination, in a loom, the shuttle* boxes, the shuttles therein, the vertical shaft H having the flier, the horizontal shaft E connected to the shaft H to be moved longitudinally thereby, the levers on the shuttle arranged to be held retracted by the tension of the weft, the spring in the shuttle for forcing said levers outwardly when the weft-thread fails, and connections from the shaft E to a stop-motion, substantially as described.
In witness whereof I have hereunto set my hand in presence of two Witnesses.
