CHANGE-GEAR FOR MECHANICAL LOOMS.

No. 930,707. Specification of Letters Patent. Patented Aug. 10, 1909.

Application led. February 18, 1907. Serial No. 357,966.

Lever l() is pulled to the left by bell crank 14, and lever 9 to the right by bell crank 12, 13'when the wires 17 are pulled.

On the main shaft 13 of the loom, Fig. 3, is provided an eccentric 19, from which by aid of

link bolts

21 and 22 and rod 20, lever 23 of the new gear is operated. The latter is rigidly fitted to the shaft 24, running in bearings in the sides of the

frame

25 and 26, Fig. 2, and carrying besides lever 23

levers

27, 28. rIfolbolts 29 and 30 of

levers

23 and 27 are linked the rods 31 and 32, to produce a connection with the blade fitted with ins 33 and 34 and oscillating in the slots in

frame sides

25 and 26. In these sides are also arranged the shafts 36-39, carrying the Vsingle armed levers 40-43 and the double armed levers 44-47. rl`he latter are connected with the lifter-levers 48-51 by wires 52l and a spring 53, so that the lifterlevers to which the lifters 5457 vare linked by means of bolts 58 are forced by the action of the spring againstpthe sto 59 provided between the frames. For eac lifter a three armed lever 60, 61, 62'is provided, supported on shaft 63. 0n shaft 64 moves loosely the

tumbler

65, 66, which by its own weight is able to hold levers 62 by means of cross piece 66 in their position farthest to the right. The numbered disks are attached to the shaftsl 67. at theplaces marked X, at the back of said shafts are the cranks 63 which by means of rods 69 are linked to levers 60.

To all whom it may concern:

i Be it known that l, FRANZ Louis WGHT- LER, director, a subject of the King of Saxony and German Emperor, residing at 5 Grossenhain, in the Kingdom of Saxony and German Empire, have invented certain new and useful Change Gear for Mechanical Looms, of which the following is a specification.

10 rlihe purpose of the present invention is to l allow of working on mechanical looms without change-card, the change being operated by hand by aid of numbered disks, handles or other suitable appliances. Hereby. the shuttles will have to always enter the same change-cells on each side of the lloom 'and may not be shot crosswise as is the case when change-cards are used.

ln the accompanying drawings, Figure 1 is a front elevation and Fig.4 2 a plan of the device. Fig. 3 is a front elevation of the device together with a change-gear, in which the shuttle boXes are adjusted by two toothed drums turning in opposite directions. Fig. 4 is a side elevation of Fig. 3.

The Figs. 5, 6, 7 and 10 show strips of paper,

used for the loom. Fig. 3 illustrates the way of such strips lof paper. Fig. 9 shows a groove, in which said strips are introduced.

ln Fig. 3 the right shuttle boX is shown partly removed, in Fig. 4 the known liftinggear with the shuttle-box has been omitted.

The new arrangement, which is arranged above the loom, is fitted with numbered disks, handles or other suitable appliances and has the same number of disks, as shuttles are used for weaving. For reason of greater simplicity of the description and the drawing only four shuttles have been employed, wherefore only disks Nos. 1-4 have been provided. ln cell 1 (Fig. 3) there is shuttle No. 1 and in cell 2 shuttle No. 2, in cell 3 shuttle No. 3 and lastly in cell 4 shuttle No. 4. Cells 5 and 6 are empty, cell 5 temporarily receiving' shuttles 3 and 4, cell 6 the

shuttles

1 and 2.

The change-gear Fig.

a manner, that by rovision of

springs

7 and 3 the levers 9 an 10 are geared in known manne-r so that the empty cells are brought in line with the lay race from the first. On

the frame-pin 11 bell cranks 12, 13 and 14, 15

are pivotally arranged, which are connected with levers 9 and 10 by means of rods 16.`

On the bosses 70 of levers 61 rest the lifters 54-57 which are raised so far by the springs 71 acting on lever 61, until the arms 60 on the cross piece 72 reach a stop and come into the position shown by the dotted lines. The numbered disk 1 belongs to lever 61 beneath lifter 34, disk 2 to lever 61 under lifter 55 and so on. If now disk 1 is turned say to the right',

until lever 61 comes m contact with crossbar 72, the respective lifter 54 will be lowered to the blade 35 and carried along by the latter in its motion from left to right, whereby at the same time shaft 36 is moved in direction of the arrow 73 and will by means of connecting wire 7-4, acting on lever 40, a bell crank 76 on the frame pin 7 5,'Figs.

bring cell 1 in known 3 and 4, and wire 17 manner in line with the lay-race. As long as this lever 62 is held by the web 66 of tumbler 65 the lifter 54 will be carried along at 111e each stroke of blade 35, cell 1 remain 1n 4 is arranged in such with the lay race and shuttle No. 1 be shot continuously back and forward. lf however another disk is turned to the right by the upper beveled surface of lever 62 the web 66 on the tumbler 65 will be raised, so as to release the former one and hold the one turned last.

In order that the weaver may only be able to turn the disks in the proper moment, and as the case may be for two, four or more successive shots per shuttle, the following arrangement is provided: 0n frame bolt 77 is arranged a lever 78 with bolt 70 and roller 80. The lever 78 is elastically connected with the frame 26 by means of spring 81. To said attached a hook 82 on which the branch 83 of tumbler 65 will rest, wl'iereby a turning of the adjusted disl s is prevented.

t every second shot the support is removed, by the lever 78 being moved in direction of arrow 84, until hook 82 is removed from the path of lever 83. This is obtained by the following arrangement: On the bolt 77 is also rigidly mounted the lever 88, which is linked by means of rod 89 and bolts 90 and 91 to lever 28. In lever 88 is fitted a bolt 92. rlhe latter carries the parts as used in a shalt machine with pasteboard cards, namely a wheel with ins 93 in which catches the reversing hoolk 911 fitted on frame bolt 95,' cylinder spider and 98 and the t each 96 with cylinder holders 97 thereto attached spring 90. stroke of frame 88 to .the right by Y th of its circumference in direction of the arrow 100. The lantern carries three

pins

101, 102 and 108 and as soon as at a stroke one of said pins 101`103 strikes against the roller 80, lever 78 is taken along into the position Fig. 3 for releasing the disks and is upon the return of lever 88 instantly returned into its original position by spring` 81.

Until now l have described the arrangement for sending the shuttle two successive shots through the shed. It may however also be shot single times, and to obtain this, the web 66 is permanently released, by removing the hook 82 or fixing lever 78 in its farthest position in direction of lever 84. Care must be taken, that wires 17 are so connected with bell cranks 12`15 that by turning the disk 1 the

shuttle cells

1 and 3 are adjusted in line with the lay race, on turning the disk 2 the cells 5 and 6, and on turning the disk 3 the cells 2 and 4'. Three shuttles may be used, shuttle 1 entering

cells

1 and 8, shuttle 2 cells 5 and 6 and shuttle 3 cells 2 and 4.

A strip oi' paper, the same as used in Morse telegraphing apparatus, must be used lor each loom. On it the colors and the numbers of shots are marked successively, as they are to be made in the fabric. The graduation on lever being said strips in. direction (L l), Fig. 5, is the same iii all mills, the distance c, `Fig. 5, giving the number oil shots to be made with the same color. lt is once marked on the sti ip, see Fig. 6, or the color or the shuttle: are numbered, see Fig. 7. The strip is introduced in a groove 1, FigsS and Sl, directly at the edge of the cloth beam on the side where the numbered disks are and moved at the same time with. the finished stull, l'rom beam 2 in di ree tion ol' arrow 3. Generally the weave will read where the arrow 4- points to, the l'ollow ol' the shots, and when a new cross l ine. a reaches this place, he must start the disk on the automatic gear corresponding with the respective 'following color. lt must however be mentioned here that certain mills use strips as shown in Fig. 10 and imlicate hcneath the line the number oll shots, which are to be made in the fabric. ln such mills it is supposed that the weaver counts the shots while weaving, which is however not always done.

The strip ol' paper comes l'rom a roller 4 on a i'ranie 5 and passes over

rollers

6, 7, 8 and 9. The rollers 6, 8 and 0 are arranged to turn only on jl'raine 5. lloller 7 however can rise and fall so as to keep the paper always tight. It is pivoted to a bar 10 which swivels around a frame bolt vided a set piece 13, which by means ol` holt 15 is linked to lever 14. At the lower end olI said lever is hinged by means ol' bolt 10 the balance 17 with

rubber rollers

18 and 10. 0n bolt 15 is provided a spiral spring, which is so arranged that

rollers

18 and 10 are pressed in direction oiA arrow 20 against the cloth beam 2. iis the paper strip is therebetween, only so much is unrolled lrom the roller 4 as finished l'abric is ren'ioved l'rom the cloth beam. The paper strip passes over roller 21 and beam 22 and is rolled up on roller 23. To said roller 23 is attached a roller 26 around which a cord is wound. The other end el this cord is rnn over a roller fastened to the ceiling oll the room and is provided with a small weight. Vilhcn this weight has worked down to the lloor, l. paper strip being rolled up, the cord is wound afresh around roller26. The paper on roller 23 is placed on bolt 27 and v-.orkcd oil' again.

he paper strip may also he suitably called pattern strip.
