Application filed fictober 7, 1922. Serial No. 592,949.
To aZZ whom it may concern:
Be it known that I, CARL Eccanr, a citizen of the Republic ,of Switzerland, residing in Arbon, Switzerland, have invented certain new and useful Improvements in Looms, of which the following is a specification, ref erence being had to the accompanying drawing, forming a part hereof.
This invention is concerned with the mechanism for effecting the required move ments of the shuttle and with devices for preventing the drawing in of the selvage warp threads toward the center line of the fabric by the action of the shuttle and the shuttle threads. In accordance with the invention motion is imparted to the shuttle. in a direction to lay the weft thread in the open shed through gear members one of which is carried by the lay in its reciprocations toward and from the cloth guide while the other has alternating or reciprocatory motion, either rectilinear or curvilinear, the two members having both a working engagement and a sliding engagement to permit the relative movement of one with respect to the other without disengagement. One of said members may be an elongated cylindrical or spur gear and the other a rack gear. Either one may be the driver with respect torthe other and either one may be mounted on the lay to reciprocate therewith. To prevent the drawing in of the selvage warpthreads by the action of the shuttle and the shuttle thread, a pin, operated bymechanism actuated in timet relation with the shuttle mechanism, is moved into position at the corresponding edge of the warps so that, as the shuttle is moved through the shed, the shuttle thread is looped about the pin and thereby prevented from drawing in the selvage warps, the pin being withdrawn when the shed has been closed.
The invention will be more fully explained hereinafter with reference to the accompanying drawings in which it is illustrated and in which- Figure 1 is a view partly in side elevation and partly in longitudinal section showing so much of a loom as is necessary to enable the application of the invention to be understood.
Figure 2 is a detail plan view, partly diagrammatic, of the selvage device.
Figure 3 is a detail view partly in front elevation and partly in transverse section, illustrating particularly the support of the shuttle in the lay and the devices whereby movement is imparted to the shuttle from phe reciprocating rack bar carried by the The shuttle a is mounted in any usual or suitable manner in the lay b and the latter is supported, as by arms 5 which have suitable bearings 0 in the frame of the loom, so as to be reciprocated toward and from the cloth guide 0, in the usual manner. Mounted in the lay, so as to be reciprocated in a transverse plane, is a gear member d, preferably a rack gear, from which motion is imparted to the shuttle in any usual or suitable mannor, as shown, for example, in FigureS. The lay may be reciprocated by any suitable means, as by a link 6 connected to a crank pin 6 of a crank disc 6 driven in any suitable manner.
Referring now to the construction shown in Figure 1, it will be noted that in a frame 79 which forms a part of the lay structure, there is mounted in suitable bearings a shaft 7 which carries a gear f in engagement with the gear rack (i above mentioned, and an elongated spur or cylindrical gear member 7, such gear member f being reciprocated bodily with the lay. Mounted in suitable bearings 0 supported by the loom frame, is another gear member 9, preferably a rack gear, which is reciprocated by any convenient means, as by a link connection 9' to a lever g which is operated by a cam groove 9 in a disc 9 As shown, the crank disc 0 and the cam-disc g may be formed with gear teeth so that the two shall operate in proper timed relation.
It will be observed that in the construction shown in Figure 1, the gear member f is reciprocated bodily with respect to the gear member 9, while the working engagement of the two gear members is maintained at all times, the rack gear 9 being in this instance the driver with respect to the driven gear member F. The gear member 7, furthermore, is at all times in operative relation with the shuttle actuator 03 through the shaft f and the gear 7, so that the shuttle at all times in the operation of the loom receives the motion necessary to lay the weft thread in the open shed.
To prevent the drawing in of the selvage warp threads by the action. of the shuttle and shuttle threads, there is provided, adjacent each edge of the warps and between the cloth guide 0 and the lay, a finger or pin 72. which is caused by suitable mecl1anism, op erating in timed relation with the shuttle mechanism, to move into position to be engaged by the shuttle thread at each movement of the shuttle. As shown, each finger h is carried by an arm h of a rock shaft h oscillated in timed relation with the other parts of the loom, through an arm 71- from a cam 72,. VVhen the shuttle has moved to one side of the warps, as shown by broken lines in Figure-2, the pin or finger 72 on that side is raised into working position, indicated in Figure 1, so that in the movement of the shuttle to the other side of the warps the shuttle thread is looped around the pin or linger 71/. When the operation has been completed and the shed closed the finger is moved out of operative position so that the loop of the warp thread will be disengaged. In this manner the pin or finger takes the strain ofthe Weft thread and prevents it from drawing in the selvage warp thread regardless of the tension of the weft or shuttle thread.
It will be understood that various changes in details of construction and arrangement can be made to suit diiferent conditions of use or the convenience of the manufacturer and that, except as pointed out in the claims, the invention is not limited to the details of construction and arrangement shown and described herein.
I claim as my invention:
1. In a loom, the combination with a lay of a shuttle actuating mechanism comprising a rack gear ((5) mounted to reciprocate on the lay, an elongated spur gear (f sup ported on the lay and in operative relation with said rack gear, a rack gear (g) in operativc engagement with said elongated gear and supported for reciprocation in fixed bearings, and means to reciprocate said last named rack gear.
2. In a loom, the combination with a lay, of a shuttle actuating mechanism comprisiug a shuttle actuator, an elongated spur gear (f supported by the lay and, in operative relation with said actuator, a rack gear mounted to reciprocate in fixed hear ings and in engagement with said elongated gear. and means to reciprocate said rack gear.
