Specification of Letters Patent.

Patented May .1 1, 1909.

Application filed October 22, 1908. Serial No. 458,923.

To all whom it may concern:

Be it known that I, WALTER E. Score, a citizen of the United States, residing at Germantown, in the city of Philadelphia, in the county of Philadelphia State of Pennsylvania, have invented certain new and useful Improvements in Jacquard Connections, of which the following is a specification.

My invention relates to a machine having a plurality of sections, whereof the machine is adapted more particularly to the making of a series of net or lace fabrics of like patterns at the same time.

In such a machine ordinarily, each division is equipped with a set of jacks mounted upon a rocking-bar and directly connected with and controlled from the jacquard through the intermedium of strings which extend from the respective lifting hooks of the jacquard to the corresponding jacks in each division. These strings extend more or less obliquely from the jacquard to the outermost and intermediate jacks, covering the face of the machine with a triangular mass (net-work), of strings of which the jacquard is the apex, the outermost strings being the longest, the middle strings the shortest and all varying in length according to their position in the machine. By reason of these variations in length, the strings, owing to weather conditions expand and contract unequally, and the control of the jacks is rendered irregular and uncertain, causing the machine to produce imperfect work and occasioning often times serious stoppages and other drawbacks, with no remedy heretofore to avoid the same other than return of normal weather conditions.

My i vention, which is designed to communicate the action of the jacquard to the jacks in equal degree and thus to assure perfect working of the jacks, under all conditions and consequently reliable production of the fabrics, consists in a compensating device interposed between each jack and the jacquard, the number of such devices corresponding to the number of jacks and the devices in each division or section of the machine constituting a set.

The members of one set are suitably connected with corresponding members in other sets and also with corresponding jacks, so that by suitable connection between the lifting hooks of the acquard and the corresponding members of one set of compensating devices, the action of the jacquard is instantly communicated to the corresponding jacks in all the divisions in unison and with uniformity of movement.

The nature, scope and characteristic features of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, in which Figure 1, is an elevational view of a number of sets of the compensating devices, showing connections between the same, also connections from said sets to the jacks as well as connections from one of the sets to the jacquard, embodying as arranged essentially, main features of my said invention; and Fig. 2, is a perspective view of a set of the compensating devices, in a disconnected condition on a shaft, separated by gaskets or Washers to maintain the same at proper distances apart thereon.

Referring to the drawings, a, ct, 0., a, o represent several sets of the compensating devices, in a form found suitable for the pur pose designed and mounted on separate shafts, certain members of the devices of the sets are connected by wires (1, as shown in Fig. 1, so that corresponding devices of all the sets can operate in unison. Each device as shown being of an inverted T-shape and provided with members a and o The member c of each device of the several sets is provided with a suitable connection 0, for connection with a corresponding I ack, not shown, while a member (L2, of each device of one set is connected by a suitable connection 8, Fig. 1, with the jacquard.

The devices of each set connected as hereinbefore described are loosely mounted on separate shafts b, separated from each otl er on their respective shafts, by washers or gaskets c, Fig. 2, to maintain the same at proper distances apart for practical ease of working.

The machine being put into operation, it is evident that the action of the jacquard will by connections 3, be instantly communicated to one set of compensating devices and then to connected devices of corresponding sets and to the respective jacks in unison, with uniformity of movement.

It will be obvious as this invention does away with the great weight and multiplicity of strings depending from the jacquard as quently with an increase of production.

It will also be obvious that while this invention is particularly adapted for use in connection with machines for making lace J curtains, the same 18 equally applicable to Jacquard looms for weaving a plurality of fabrics, or to any machine in which it is desired to move a plurality of elements in unison, through a connection to a jacquard. And finally the construction and arrangement of the device illustrated in the drawings may be changed or modified, without departing from the spirit and scope of my present invention.

Having thus described the nature and objects of my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a machine of the character described, a plurality of jacks or heddles, a jacquard, compensating devices interposed between the same, means connecting said devices, means connecting each of said devices with one of said. jacks or heddlcs and means connecting one of said devices with said jacquard, whereby action of the jacquard is communicated to said jacks or heddles with uniformity of movement, substantially as and for the purposes described.

2. In e machine of the character described, a jacquard, ecks or heddles, oscillating devices arranged in series on separate shafts and means connecting the same to move them in unison, one member of each of said devices having connection with a jack or heddle and one member of one of said devices heving connection with said jacquard, substantially as and for the purposes described.

3. In e machine of the character described,

a jacquard, jacks or heddles and devices arran ed between the jacquard and jacks or hedoles, means tor connecting said devices with each other and with said jacks or heddles and a connection from the said connected devices with said jacquard, substantially es and for the purposes described.

In witness whereof, I have hereunto set my signature in the presence of two subscribing witnesses.

WALTER R. SCOTT.
