SPECIFICATION forming part of Letters Patent 0. 600,216, dated March 8, 1898. Application filed September 25,1897. Serial No. 652,954- (No model.)

To (0 whom it may concern.-

Be it known that I, HENRY EASTWOOD, a citizen of the United States, residing in Lake View, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Looms; and I do hereby declare the following; to be afull, 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 of reference marked thereon, which form a part of this specification.

My present invention is an improvement on United States Letters Patent No. 377,425,

' granted to me on February 7, 1888, and besides embodying thefeatures covered by said patentthat is to say, to provide a loom by means of which two or more pieces of fabric can be woven side by side in one loom with perfect selvages on both sides of each pieceit also embodies means by which the construction of said loom is simplified and perfected and thus the said loom rendered more effective, stronger, and more reliable in operation.

The invention consists in the improved loom, its harness-operating mechanism, in the picker-stick-controlling mechanism, and in the combination and arrangements of the various parts, substantially as will be hereinafter more fully described and finally embodied in the clauses of the claim.

In the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure 1 is a front elevation of a loom provided with my improvements, certain portions being broken away and others removed to better illustrate the nature of my said invention; Fig. 2, an end elevation of Fig. 1, viewed from the right-hand side; Fig. 3, a sectional view on the line a: a: of Fig. 1, looking in the direction of the arrow B; Fig. 4, an enlarged detail sectional view on the line y y of Fig. 1 with'certain portions removed to better illustrate the arrangement of certain harness operating and controlling rods and levers; Fig. 5, an enlarged detail top plan view of a portion of the lay; Fig. 5, an enlarged top plan view of the adjacent portion of the breastbeam adapted to cooperate with said lay; Fig.

6, an enlarged detail rear elevation of the spring-controlled reed and of a portion of the lay carrying the same; Fig. (3, a sectional view on the line ,2 z of Fig. 6; Fig. 7, an enlarged detail View of a certain connection between one of the picker-sticks and the connecting-links, and Fig. 7 a a sectional view on the line 1) o of Fig. 7. r

In said drawings, A represents a loom having a series of supporting-frames A, a driving-shaft at, extending throughout the entire length of the loom and carrying at certain intervals a series of cranks a, connected by pitmen a with a lay a in the usual manner. The said lay is supported by a series of downwardly-projecting lay-swords a pivotally secured, as at a, to the top of the supportingframes A. a

On the cam-shaft b, and at or near each end thereof, is mounted a tappet 1), adapted to operate a tappet-lever b fulcrumed at its rear end, as at W, and to the free end of which is secured one end of a leather strap b, the other end of which is connected to the substantially horizontal arm b of the angle-lever b, fulcrumed, as at 12 to a connecting-bar b which latter is secured to the front of the lay- 8o swords, as clearly illustrated in the drawings. On the said connecting-bar b and at certain intervals are pivotally secured the pickersticks c, the end sticks being controlled by spiral springs 0, carried by arms 0 projecting from and secured to the outer portions of the said connecting-bar b The intermediate picker-sticks and also the angle-levers b are connected by a series of metallic links 0 and intermediate leather 9o straps 0 the latter being held in proper position on their respective picker-sticks and angle-levers by vertically-arranged leather straps 0 while the leather straps 0 arranged on the angle-levers b b, are connected with 5 p the end picker-sticks by means of flexible links 0", held in proper position on said end picker-sticks by leather straps 0 which latter arrangement is necessary to insure a perfect working of the picker-sticks, as will be manifest.

On the rear of each angle-lever is arranged a bridge cl, penetrated by a jointed longitudinally-adjustable arm 01, having a said picker-sticks would rebound from the shoulder d (adapted to engage the lower end of the bridge during certain stages of the operations,) and which arm is pivotally secured to and carried by the lay-swords a. The adjustable feature of said arm is secured by means of a slot arranged in one member of said arm and penetrated by a bolt carried by the other member of said arm, as shown. The free end of said arm is connected by a cord 02 to one end of the fulcrumed lever (1 the other end of which is connected by a cord d to a 'treadle-lever d adapted to be'operated by a cam e, mounted on the cam-shaft Z). (See Figs. 1, 2, 3, and 4.) It will be manifest that unless some such means for retaining the picker-sticks temporarily at each limit of their respective movements were employed buffers (hereinafter described) to an undesirable degree and thus obviate the effect of their full return stroke.

The lower portions of the picker-sticks c are adapted to operate in elongated slots f, arranged at certain intervals in the lay a and are limited in their movement by elastic buffers composed of leather straps f, secured to and carried by spring-loops f which latter are arranged on a rod or tube f mounted in brackets f projecting upwardly from the lay a (See Figs. 1 and 5.)

The shuttles are guided between the back f of the lay a and the guide-shoe f which latter is provided with outwardly-projecting pins f connected by looped spring-wires f which latter, with theirlooped portions, are secured, as at f, to the top surface of the said lay. By this arrangement the guideshoe is swiveled in its center, and thus permits the shuttles to enter from either side, as will be manifest.

On the rod or tube f are loosely arranged collars g, carrying downwardly-projecting arms 9, to which are secured the reeds g and which reeds are intermediately arranged between the elongated slots f in the lay a Each reed g is arranged with its lower portion within a recess g in the back of the lay a and is held within its recess by the shanks or arms 9 projecting from the rod 9 which is mounted on the lower portion of the lay and is controlled by a spiral spring 9 all as clearly illustrated in Figs. 6 and 6.

To the breast-beam h, Figs. 2, 3, and 5 are secured downwardly and inwardly projecting guide-brackets h, in which are loosely arrangedthe trunnions of the cloth-beam h which latter is in frictional contact with the drum h mounted on the shaft h, receiving at n, on a shaft supported in brackets 71",

which. latter project from the supportingframe A. The lower portions of said levers penetrate and are guided by a grid 41 and have their free ends pivotally connected to a seriesof horizontally-arranged rods 0, 0', 0 0 0 and 0 respectively, which rods are guided upon rollers 0 suitably mounted in brackets 0 which latter brackets also serve as bearings for a series of grooved pulleys 19, 19, 19 19 p and 19 over which pass a series of cords, connected to the lower shafts of the various harnesses (with the exception of the.

first or front harness) and having their free ends removably secured to their respective horizontal rods 0, 0', 0 0 0 and 0 Seven sets of harness are employed for weaving the goods with finished edges on both sides. the rear and front sets respectively, while the sets r and r produce the selvage. The extra The sets of harness r r and r r are set r is adapted to coeperate alternately with g the sets and r -to thus produce the doup, as will be manifest. For this purpose the upper shafts of the respective harnesses are connected by wires with a series of jacks 3,

=8, s s s s and s in the following manner: The upper shaft of the harness set 0 is connected by wires with the upper ends of the jacks 8 while the lower ends, of said jacks s are connected by wires to the upper shaft of the harness W. The upper ends of the jacks s are connected by wires with the upper shaft of the harness 1, while the lower ends of said jacks are connected by wires to the upper shaft of the harness r. The jacks s, 8, s s and s are connected in a similar manner by wires with the upper shafts of their respective harnesses r, r, r 0' and T with the exception that the upper end of one of the jacks s is connected by a wire s (shown in dotted lines in Figs. 1 and 3) with the short end of a floating lever 0", while the other end of said floating lever is connected through a wire with the lower shaft of the harness r Said lever is controlled by a spiral spring r as clearly illustrated in the drawings.

. In operation, when the tappet b on one side of the machine in its downward movement depresses the tappet-lever b the latter through its strap connection 11 operates the fulcrumed angle-lever 11 (by being attached to the short arm 6 of the an glelever,) which in turn throws the picker-sticks c c and thus forces the shuttles through the sheds formed by the warps by means of their respective harnesses. The

picker-sticks remain in the position attained by means of the lever 01 having engaged with its shoulder (Z the bridge (1 of its respective angle-lever b until the tappet b on the other side of the loom depresses its corresponding tappet-lever Z2 which in turn through its strap connection I) operates the angle-lever b and returns the picker-sticks to their former positions, during which operation the shuttles are again thrown through the sheds then formed. The releasing of the shouldered lever cl from the bridge (1 on the angle-lever b is accomplished by the cam e on the camshaft 5, which cam at the required moment depresses the lever d and through the cord (1 the fulcrumed lever (1 the other end of which is connected through a cord d with the free end of the shouldered lever d.

It will be understood that the various sets of harness controlling the warp-threads in the formation of sheds are operated by the fulcrumed levers n, n, 72 n 01 and n and their cooperating parts by means of the cams m, m, m m m, and m respectively, and that said cams are set in such a manner on the shaft 2' that the sheds are formed previous to the throwing of the shuttles by their picker-sticks.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. In a loon1,the combination with the frame, of lay-swords depending therefrom, a lay carried by said lay-swords, a connecting-bar for said lay-swords, bell-crank levers and pickersticks operati vely connected together and fulcrumed on said connecting-rod, means for op erating said bell-crank levers, elastic buffers for the picker-sticks, bridges carried by said bell-crank levers, shouldered arms pivotally connected to said lay-swords and penetrating said bridges and adapted to engage the same, and means for operating said shouldered arms, substantially as described.
