Specification of Letters Patent.

T 0 all whom it may concern:

Be it known that I, CARL MORIGGL, a subject of the Emperor of Austria-Hungary, and a resident of Arbon, Switzerland, have invented certain new and useful Improvements in RibbonLooms; and I do hereby declare the following to he a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in ribbon looms and has for its object to provide a 100m in. which the objectionable friction and tension of the threads are avoided and in which the threads are prevented from sticking to each other When the shed is being formed.

Instead of the ordinary straight leaves which move in a straight line, the loom constructed. according to the present invention is provided with circular leaves, the radius of the curve being equal to the distance from the leaves to the point Where the Weft threads are inserted, said leaves being adapted to turn on apivot, the axis of which is at said point where the weft threads are inserted.

.The tension of-the warp threads in. passing from the upper shed to the lower shed, and vice versa, is compensated. by movable Whips. To prevent the threads from stick ing to each other and being taken into the Wrong shed, a finger is provided which enters the shed and separates the threads of the shed before the .weft threads are in sorted. Lastly, a guide forfthe shuttle is provided which oscillates the shuttle about a given, which is in front of the point Where the weft threacs are inserted. The thread guide is situated at about this point, so that the distance through which the guide moves smaller than that moved through by the shuttle itself, and in consequence, only so much thread is drawn off from the spool as is necessary for the Weft.

In shuttles in which the thread guide and the shuttle travel through the same distance, more thread is drawn off the spool than is necessary for the Weft, and the excess thread has to be stretched which causes considerable friction of the thread against Which does the stretching,

In the accompanying drawings, Figure l, is a side elevation of the loom partly in section. Fig. 2 is a section on line 2-43 of Fi 1. Fig. 3 is an elevation, and Fig. 4 a plan view, partly in section, of the device separating the warp threads. Fig. 5 elevation, and Fig. 6 is a plan Vibe of the means for oscillating the ut'tie. F 8 and 9 are detail views of parts servi the latter purpose. Fig. 10 a detail. view of the feed for the finished ribbon, and Big. 11 is a detail view of the reed actuatng mechanism.

The loom is provided with two leaves as 1 and 2, in which are fixed the heddles 4 and 5 supporting the Warp threads 3, 3. One series of Warp threads is guided through the heddles of leaf 1 and the other series through those of leaf 2. Both leaves are circular in shape, their radius being equal to the distance from point 6, where the Weft threads are inserted, to the leaves. The lea es are supported on arms 7 and 8 which are linked to them and turn on shafts which are sup ported in the frame of the loom on both sides of the Way for the ribbons. tion is imparted to the by a 1 shaft 10 having cranks 11.. 12 which are connected to the leaves lay pitman rods 13 and 14. The cranks are at lSU to each other to, effect the alternating up and clown movement of the leaves when forming the shed.

l5 and 16 designate two guiding rollers, the roller 15 being journaled in fixedbearings, and roller 16 is pressed againstthe roller 15 and the ribbon bf? springs 1?). Stationary guide as 1.7 is a .1; provided for the ribbon. The roller 15 is rotated by means of a Worm-Wheel 15 on the shaftof said roller, which wheel engages a worm 56 on a shaft 56. A lever 57, (Fig. 10)- is pivoted on the shaft 56 and curries a spring urged pawl which engages a ratchet wheel 59 mounted on said shaft 56. The lever 57 connected by a rod (30 an o illutorv lever one of 62 which is pivoted at 31 on the in.

the machine (Fig. ll). .l lotion is imparted to the lever 32 by means of a roller l 'l i engages a groove 63 formed in the end of a roll 36 fixed on the shaft 10. A second spring-controlled pawl 65 engages the ratchet Wheel 59 and prevents shaft from being turned in the wrong direction. The object of this mounting is to insure that the length of the warp threads will always be the same whatever the position of the leaves may be. and consequently, friction of the threads in the heddles is prevented.

\Vhips 18 and 19 serve to compensate the tension of the warp threads when the shed is being formed. Apparatus for the same purpose is known. but in these. all the warp threads are guided over one whip which under the effect of a pull back spring tensions the series of warp threads supported by each of the leaves. In order to do away with this drawback each series of warp threads in the present loom is guided over a separate whip. and both the whips turn on a common pivot 20. The angles through which the whips turn correspond to the amount of tension in the threads when changing the shed. The whips are approximately rectangular frames and the whip 18 is free to move within the whip 19. Both whips are connected at their lower ends to a cross piece 22 which is connected centrally to a spring 21, the tension of which is regulated by means of a rod 23 and a nut 24.

The warp threads 3. 3 a re guided tl' rough holes in the upper part of the whips 18. 19, under shaft 20 to a shaft 25. Pins 26 are suspended from every warp thread and by their weight compensate tension in the sev eral threads and also serve as warp stops. The pins after falling down may be raised again by a lever 27. When the threads are raised or lowered by the leaves 1 and 2 to form the upper orlower shed. the threads passing from the leaves through the whips and under shaft 20 allow a rocking of the whips which a re on a. single shaft. and under the tension of a single spring. The lengths of the threads from the leaves to the whips are always the same. and consequently the tension of the threads is also the same. 'hcn. for example. the threads are lifted from the lower into the upper shcd. the spring :21 is able. when the threads are in the. center of the shed. to turn whip 19 in the direction of the arrow. Fig. 1. \Vhen the threads are raised further into the upper shed. tension is put on them again and they pull the whip 1!) back to the left against the tension of spring 21. When the threads are moved from the upper shed into the lower shod. spring .21 will pull the whip 18 to the right when the threads pass through the center in the lower shed. and the whip 18 will be pulled back to the left. it follows that the tension of the threads passing through one of the whips is compensated independently of the compensation of the tension of those passing through the other whip. The cross piece 22 during the alternating action of spring 21 on the whips, pivots alternately on its point of attachment to the one and to the other whip, while, when the threads are in the center of the shed the action of the spring is the same on both whips. This warp tension regulating mechanism [10) ac is not herein claimed as it has been made the subject matter of a separate Patent, No. 1,104,377, granted July 21, 1911 on a divisional application.

It often occurs that when the shed is opened some of the warp threads stick to others, in consequence of knots or rough parts which they ma y have, and are taken with them in the wrong direction, get into the way of the shuttle and are broken by it as it passes through the shed. This is avoided by the device shown in Figs. 3, 4, and 5 in which a movable member is made to pass through the shed laterally and thereby separates the threads. In the form illustrated this device consist of a pivoted forked finger 28 carried by a shaft 30 arranged laterally to the reed 29. The shaft 30 has teeth 31.(Fig. 4) which are engaged by a toothed arm 33 carried by a shaft 32. A roller 34 on the arm 33 engages a groove 35 in the roll 36 fixed on shaft 10 by which the fork 98 is oscillated so as to make it enter the shed laterally and move toward the reed 29 before the weft is inserted. \Vhen in consequence of any obstacles, say knots or roughened parts, a thread sticks to the adjacent one when the shed is opened and is taken, say into the upper shed instead of moving into the lower shed, fork '28 on its inward.movement will separate these threads. The weft is then inserted between the prongs of the fork 28, and then the latter is withdrawn out of the shed.

The shuttle comprises a segmental slide 37 (Figs. (3 and 7). and a holder 38 in which the welt spool 3!) is mounted and a thread guide 40 made integral with the holder 38, is provided with a threading eye 41 which is near the point (i where the weft is inserted. that is. near the. reed 29. The shuttle is adapted to move to and fro in an annular guide 42 which is interrupted at 43 to allow the warp threads to pass when moving up and down in order to open or close the shed. Movement is imparted to the shuttle by a lever 47 mounted on a shaft 46 which has a lever carrying a roller which engages a groove 44 in the roller 36. Pivoted on lever 47 is a coupling member 48 (Fig. 7) having curved projections 49 and 50 and a roller 51 engaging a slot 52 of a projection 53 beneath guide 42. The slot 59. has an upper and a lower part connected by an incline. The coupling member 48 serves to connect the slide 37 to the lever 47 by one of the projections 49, 50 engaging recesses 54, 55 of slide 37, so that the slide is bound to follow the movement of lever 47.

11. In a ribbon loom, leaves for forming the shed of the Warp threads, a movable member for entering the shed and separating the threads which stick together, a shuttle for passing the Weft thread through the shed when the shed is opened, a curved guide for the shuttle, means for reciprocating the latter about an axis adjacent to, but in front of, the point of separation of the Warp threads, and a guide carried by said shuttle and having an eye therein adjacent to said shed opening member.

In testimony that I claim the foregoing 15 as my invention, I have signed my name in presence of two subscribing witnesses.
