WALTER R. SCOTT, OE IPHILADELEPHIA, PENNSYLVANIA, ASSIGNOB TO JOSEPH H. BROMLEY, OF PHILADEIEHIA, PENNSYLVANIA.

JAG QUARD CONNECTION.

Application filed May 31, 1910.

To (ZZZ whom it may concern ie it known that I, WALTER R. SCOTT, citizen of the United States, residing in the city of Philadelphia, State of Pennsylvania, have invented certain new and useful improvements in Jacquard Connections, of which the following is a full, clear, and er; act description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to machines employing a plurality of sections of thread-controlling jacks 0r heddles actuated by one or more jacquard machines, and consists of connecting actuating devices between said elements. In substance it comprises the substitution for the compensating element of the jacquard connection shown and described in my prior U. S. Patent No. 921,288 dated May 11, 1909, of animproved form and character of the compensating element, and also a carrying forward of the invention disclosed in that patent, whereby the plurality of sections may be actuated, by such jacquard connections, in sets; that is to say one jack of one section in unison with a corresponding ack of another or other ections in the series of sections.

In the accompanying drawings illustrating my present invention; Figure 1 is a side elevation of a plurality of my new compensating elements connected in series which in turn connect the several jacks in a section or series of jacks to each other and to a jacquard machine. Fig. 2 is a like view of part thereof illustrating an arrangement thereof whereby the corresponding jacks in a series of sections may be operated in sets; and Fig. 3 is an end elevation thereof showing the method of mounting the compensating devices on their shafts.

As stated in my previous patent mentioned, the primary object of the invention therein described and in this is to substitute for the series of textile strings, of great and unequal lengths between the jacquard hooks and the jacks controlled thereby, of means largely, if not wholly, metallic, of compactform, due to their intrinsic character, and adapted to communicate the action of the jacquard to the several jacks in equal degree and with certainty of action, whereby uniformity in the product fabric made by the machine, may be had as an ultimate result, aside from the assured per- Specification of Letters Patent.

fect working of the acks, under all conditions.

The invention is applicable as well for use with Jacquard looms for weaving a plurality t' fabrics, or to any machine in which it is desired to move a plurality of movable elements in unison through a jacquard connection, and particularly develops its greatest utility in connection with lace curtain machines in which there are a series of sections of jacks operating to produce a corresponding plurality of the same pat-tern, in the curtain, each jack being mounted independently on a rocking bar, and actuated or controlled by a directly operative connection with the jacquard machine, the jacks being operated in sets composed of corresponding jacks in each of the several sections, and in unison through appropriate lifting hooks of the jacquard.

1n the operation of the device of my former patent I found that while it operated perfectly to perform the functions stated and desired, the particular form and mode of operation of the compensating element shown was such that the wires connecting each two contiguous compensating members in a series necessarily crossed each other and produced objectionable friction and wear. My present form of compensating element and its mode of operation are such that the connecting actuating wires between contiguous compensating members are reduced one-half in number and are all in the same horizontal plane; the lifting action of each on the particular jack with which it was connected made more direct and certain; and finally that the useful application of the new compensating member could be extended by applying it, in inverted position, and by a pair of suitable connecting wires one horizontal and the other vertical, between the last in sequence of compensating members in a set and the lifting hooks of the jacquard, to operate a connected set of jacks as an entirety, through the one direct connection with the jacquard, and also to accomplish the greatlydesired end of locating the jacquard entirely to one side of the series of jacks so actuated and hence in a decidedly lower plane than formerly.

Referring now to said drawings illustrating an application of the invention to a lace curtain machine, the compensating member is constructed in the form of a bell crank lever, indicated in a series of them as at .100, in Fig. 1, and mounted rotatably on shafts indicated at 82, with one arm 103 of the lever extending horizontally, and its other arm 10 1 extending vertically. Each lever is provided with a laterally-extending hub 109, shown in Fig. 3, in order that a number of them may be mounted in spaced relation on the same shaft 82. The levers in a set are connected, one to the other, by a wire 105 drawn through perforations (3, (3 in the upright arm 10a, and each is connected to a jack, through the medium of its lifting cord 64. and intermediate adjusting. device 98, by a depending wire 66 drawn through a perforation 9 in the horizontally extending arm 103 of the lever. It will thus be seen that, while each lever directly and independently actuates the particular jack with which it is thus alone directly connected, the series of levers in the set are so connected that a sidewise pull on the vertically-disposed arm 10% of the last lever in the series will rock all of them on shaft 82, and which action will, in turn, lift all of the jacks, in such set, in unison. In order to give such sidewise pull to the terminal lever, there is connected to its upright arm 10% a wire 106 similar to and arranged in the same plane with the set of jack-connecting wires 105, the opposite end of this wire 106 being connected to the arm 107 of another bell-crank lever, indicated at 10%, mounted rotatably on a shaft 84, and precisely similar in construction to the other levers 100, but arranged thereon in relatively inverted position, so that when rocked on its shaft its arm 107 will have a sidewise instead. of a vertical movement and its arm 108 a vertical instead of a sidewise motion. Drawn through perforation 8 in said arm 108 of lever 10 i is a wire 77 leading, through similar adjusting devices 80 as before, tothe lifting hooks of a jacquard machine.

My present form of compensating devices enables me to arrange and operate the j rick-actuating connections, and their shafts, in staggered relation, as indicated in Fig. 2, which has advantages when operating corresponding jacks in the several sections, in sets, and so actuating them by means of corresponding lifting hooks of one or more jacquard machines. By reference to Fig. 3 it will be seen that this form and character of compensating device, operatively connecting a plurality of jacks in series, and as employed, in reverse position to connect the series as a whole with the jacquard machine, lessens the number of compensating devices and all crossing wires, and, as com pared with my former device of said Patent No. 921,288, also enables me to arrange the jacquard machine in a vertical plane entirely to one side of that of the whole series of jacks operated thereby and also in a horizontal plane very much lower than when employing the form of compensating device of my said former Patent No.

921,288; and also finally to utilize my present form of compensating device in such described relative arrangement with the jacquard machine,'which is also shown and described in a pending application for pat ent filed by me on March 17, 1910 Serial No. 5%),907, and in substitution for the roller devices shown therein, between the jackactuating connections; but as I have, in said application, claimed said arrangement of elements, broadly, I do not claim the same herein save as a specific form thereof, comprising as an identifying element the particular connecting and compensating element herein shown and described and in the specific combination thereof with the wire connections between the series of jacks and the jacquard machineactuating the same.

Having thus described my invention, I claim as new and desire'to secure by Letters Patent 1. In a machine of the character recited,

a plurality of independently movable acks, 7

constituting a section thereof, a shaft, a series of inverted bell crank levers each having a bored laterally extending hub and mounted thereby in spaced relation to rock on. said shaft, vertically disposed lifting means between each jack and the horizontally-disposed arm of each lever, and. means connecting the appropriate lifting hooks of a jacquard machine with the other and vertically-disposed arm of each corresponding lever inthe series.

2. In a machine of the character recite-d, a plurality of independently movable jacks, constituting a set of jacks, a series of shafts over each jack in the set, an inverted bell crank lever on each shaft, provided with a bored hub adapted to be mounted thereby to rock on said shaft, vertically disposed lifting means between each jack and the horizontally-disposed arm of its corresponding lever, means between the upright arm of each contiguous lever in the series, connecting the set of levers, in tandem, movable actuating and guiding means operating to impart a sidewise motion to the upright arm 7 of the last lever in the series, and means between the lifting hooks of a jacquard machine and said movable guiding means, operating to simultaneously rock the entire series of levers in the set. i

3. In a machine of the character recited, a plurality of sections of independently movable jacks, arranged to be operated in sets of corresponding jacks in the several sections, a series of shafts mounted in relatively different horizontal planes, one shaft for each section of jacks, a series of inverted bell crank levers mounted on each shaft, in spaced relation to each other, and adapted to rock on said shaft, vertically disposed lifting means between each jack in a section and horizontally--disposed arm of a corresponding lever on its shaft, means connecting the upright arm of contiguous levers in a set, in tandem, to a set of corresponding jacks in the several sections, and a series of movable guiding levers connecting the appropriate lifting hooks of a jacquard machine with the terminal member in the series of levers actuating each set of connected Jacks.

In testimony whereof, I have hereunto afday of May fixed my signature this third A. D. 1910.
