ALEXANDRE BARBIER, OF LYONS, FRANCE.
APPARATUS FOR OPERATING GUIDED SHUTTLES IN LOOMS.
SPECIFICATION forming part of Letters Patent No. 708,752, dated September 9, 1902. Application filed August 6, 1901. Serial No. 71,021. (No model.)
."l'o all whom, it may concern:
Be it known that I, ALEXANDRE BARRIER, a citizen of France, residing at Lyons, France,
' have invented certain new and useful Improvements in Apparatus for Operating V Guided Shuttles in Looms for Simultaneously 'Weavin g Several .Pieceswith Several Shuttles, of which the following is a full, clear, and exact description, and for which I'have made application for patent in France, dated January 30, 1901.
Myinvention is applicable to looms in which several pieces are simultaneously woven, each with,several shuttles, and inwhich the shuttles instead of being thrown are driven during their entire courseas, for example, in ribbon-looms. Its object is to permit the rapid working of the loom, whatever may be the number of the shuttles, by preventing the latter from participating in the motion of the batten and by driving them by simplifie mechanism.
The invention is illustrated in the accompanying drawings, which represent the parts of the loom which have been modified by my invention.
Figure l is a View of a loom behind the shuttle-carrying frame. Fig.2 is a view of half of the front of this frame. Fig. 3 is a view of half of the back of the same. Fig. 4 is a vertical section of Fig. 3. 'Fig. 5 is a horizontal section of the same figure. Fig. 6 is a side elevation of the mechanism. Fig.
7 is a front view of the same. Fig. 8 is a detail of the cams 3 acting on the frame.
The shuttles n are carried by a frame a a, which does not form-part of the batten. The latter consists simply of the combs b b, of equal number to that of the pieces being woven, (two in the drawings.) The frame a, equilibrated by counterweights or springs, moves vertically the length of the guides ff to bring the required shuttles in front of the combs b. This motion is obtained by any known mechanism and so much more easily as the frame remains always in the same vertical plane. .Theshuttles 'n, Fig. 2, are arranged on the frame a in superposed ways or races cc and in as many vertical rows plus one as there are pieces to be woven. Be-
tween these vertical rows are provided openings 0 0, within which work the combs b b,
ions, 0 c, mounted on hollow axles, which render them capable of independent movement, are respectively fixed to other pinions a) t', situated atthe upper part and at the lower part of the frame anddriven by racks g g, running the entire length of this frame. Each rack g thus operates all the shuttles placed on the same horizontal line and causes them to execute similar movements in each of the pieces being woven. To this point these arrangements are similar to those applied to movable battens.
I will now explain the new arrangements which enable the racksg to be operated at the desired time. I will explain first that in order to give these racks a reduced motion, thus enabling the length of the frame to be reduced, I have given tothe pinions i, which .they operate, a smaller diameter than that of the pinionsc, which drive the shuttles. At the two extremities of each rack g, Fig. 3, are attached very flexible metallic ribbons 'm, which pass around guide-pulleys h h and are fixed to runners j j, sliding in horizontal grooves in. The same arrangement is repeated at theright and left of the frame a.
The grooves la are placed opposite the shuttle ways .or races 8 e on the opposite face of theframe a. Each runner j is situated at the same height as the horizontal row of shuttles which it drives. form of a projecting horizontal rib, beveled off at the front part and on the rear of which the pickers l, sliding horizontally on eachside.
of the frame at the height of the combs b, can act. position in height of the frame the two run.- ners situated opposite thepickers Z are those which drive the shuttles which are required to operate. Only one of these runners is at the end of ,the groove near the picker. It is the one required to be operated. The other is at theend of the groove the most remote The result is that whatever may be-the Each runner has the rom the picker, where it is held by a spring I z, entering an annular notch formed at the top of the bevel of the runner. This latter should not be operated. It is therefore necessary to render the picker corresponding to it immovable, which I obtain in the following manner: The pickers Zare driven by picking-sticks p 19. (Seen in front elevation at Fig. 1.) Each is mounted on the same axle with an operating-lever g, which is operated at each blow of the batten by a cam or by other known operating mechanism acting on the cords or hands y y. The connection of the leverp with the operating-lever q is effected by means of a pawl 7", which can come into contact with a projection s on the operating-lever q. This pawl r is raised by a lever 15 every time that the picker-sticks are not. required to operate. For this purpose when one of the runnersj is pushed by the picker Z it raises by its inclined plane the spring .2 corresponding with it. This spring raises in its turn a pulley to, Fig. mounted on one arm of a crank-lever 'v, pivoted to a fixed point of the framing, the other arm of the le ver -v being connected by a cord :1: with the lever t, Fig. 1. This lever then raises the pawl 0', and the operating-lever (1 works without carrying with it the picking-stickp or the picker Z. When the frame a rises or falls for a change of shuttle, the springs .2 which have been raised by the runners, also raise the pulley u by passing in front of it. It therefore results that whatever may be the position at which the frame stops the ru nnerj, which has been driven, holds the pulley a raised and rendersimmovable the correspondingpicker Z. The vertical displacement of frame a, carrying the shuttles, is obtained by means of the jacquard and by any means knownfor instance, that shown in Figs. 6, 7, and S. The frame a is connected by connecting-rods 1 to two brakes 2, engaged by one of their ends in the spiral cams 3, which are fastened upon a transversal axis 4:. The rotating movements of the latter are thus transformed into ascending or descending movements of frame a, and the starting of each shuttle n corresponds to a certain position of axis 4. Axis 4 receives these positions by means of a drum 5, acted upon by a series of chains 6 6, in
completely stretched, drum 5 takes a certain position, which latter varies for each chain and to which the starting of a corresponding shuttle answers. The raising of the rods 7 is effected by a claw 14, receiving a vertical oscillating motion by crank 9 and lever 10. This raising is governed by the jacquard, which, by means of the cords 11, raises at every stroke one of the levers 12. The latter allows one of the hooks 13, attached to the rod 7, to hook upon the claw 14-. Thus every time that the jacquard raises one of the cords 11 one of the rods 7 is raised by the claw 14- and the drum takes a corresponding position, which it transfers to frame a.
Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-
In combination, a batten, a shuttle-carrying frame a, independent of the batten, means for giving said frame a rising-and-falling movement, rows of shuttles arranged to move on said frame, racks 9 carried by the frame, pinions i and c of differential diameterdriven by said racks and in turn driving the shuttles, runnersj moving on the frame and situated at the same height as the shuttles corresponding with them, means connecting the runners with the racks, pickers Z, pickersticks 17 for operating the pickers, said pickers being arranged to push the runners which are at their level and locking means for preventing the picker-sticks from operating, said locking means being controlled by the runner which has just been driven, substantially as described. I
In witness whereof I have hereunto set my hand in presence of two witnesses.
