LOOM.

SPECIFICATION forming part of Letters Patent No. 572,246', dated December 1, 1896. Application tied Jaimy 9,1896. serai No. 574,808. ci@ man To all whom, it may concern:

Beit known that we, ROBERT CUSCADEN and WILLIAM F. PoIEsz, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Looms; 'and we do hereby declare the following to be 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.

Our invention consistsin the novel features hereinafter described and claimed, reference being had to the accompanying drawings, which illustrate one form in which we have contemplated embodying` our invention, and

said invention is'fullydisclosed in the following description and claims.

Referring to said drawings, Figure l represents a front elevation of an apparatus embodying our invention. Fig. 2 represents a vertical longitudinal sectional view, slightly enlarged, showing the air chest, the tubesheet, and portions of the air tubes or cylinders. Fig. 3 represents an end view of the apparatus, showing the tube-sheet down, the lower portions of the air-tube being broken away. Fig. 4 represents a similar view showing the tube-sheet in engagement with the air-chest and both parts in elevated position.

In carrying out our invention we provide a loom with a vertically-movable tube-sheet A, which is provided with a plurality of downwardly-extending air tubes or cylinders B, in each of which is a piston C. To each of these pistons is secured a downwardly-extending warp-thread-car1ying rod D, projecting from the lower end of its respective tube and provided with an eye d or equivalent device to hold one of the warp-threads b. The tubes or cylinders B may extend entirely through the tube sheet or register with apertures therein, as desired, and there may be any desired or necessarynumber of these tubes with their pistons C `and warp-holding rods D. Within each of the tubes or cylinders is a coiled or other sprin g T, preferably surrounding the warp-carrying rod and arranged to press upwardly upon the piston C, thus maintaining the pistons and their connected warpcarrying rods D normally in their highest positions.

Y Above the tube-sheet A is a compressed-air chest E, which is provided interiorly with a horizontal partition F, dividing the chest into an upper or compression chamber c and a lower or distributing chamber dx. The lower face of the air-chest E is provided at each side, preferably, with down wardly-extendin g guide-rods K, which engage guiding-recesses i t' in the tube-sheet, thereby securing the tube-sheet and air-chest from lateral Inovement with respect to each other, but permitting a vertical lmovement of the tube-sheet with respect to the air-chest, as hereinafter described. The air-chest E is normally supported upon brackets or supports 7i; 7c, which are provided upon the loom-frame, and in this instance said air-chest is provided with lugs or projections j j, extending laterally therefrom, which rest upon said brackets and support theair-chest. Y

The bottom ofthe air-chest, which forms the bottom of the distributing-chamber dx, is provided with a series of holes G, circular in form, which are of substantial] y the same size as the bore of the tubes or cylinders B, and said apertures are so arranged that each is directly in line and adapted to register with one of said tubes B when the tube-sheet and air-chest are brought together. The meeting faces of the air-chest and tube-sheet are provided each with a sheet of elastic packing of felt or other suitable material having circular openings cut therein to register with the apertures in the air-chest and tube-sheet, the packing for the lower face of the air-chest being indicated by I and that for the upper face of the tube-sheet being indicated by J. It will thus be seen that if the tube-sheet be raised into contact with the air-chest the apertures G in the latter will register with the tubes B, and the packing-surfaces I and J will make tight jontsbetween the parts.

In order to admit air to the distributingchamber (ZX, we provide the partition-F with one or more openings c, each of which is provided with a valve H, having a valve-stem f, which preferably extends above and below the same', the upper portion 7i extending into IOO a guiding recess or collar h, formed in the top plate of the air-chest, and the lower part f extending downwardly through the bottom of the air-chest and havingits lower end projecting slightly below the packing I thereon. Each of the valves II is provided, preferably, with a spring to hold it upon its seat, a coiled spring g being shown surrounding the upper part h of the valve-stem.

Q represents one of the pattern-cards for con trolling the movement of the pistons C and their connected warp-carrying rods D and warp-threads b. These cards are adapted to be placed upon the top of the tube-sheet A between the guide-rods K while the tubesheet and the air-chest are separated, as shown in Figs. l, 2, and 3, and each card is provided with perforations adapted to register with the tubes, the warp-threads of which are to be depressed in forming the shed. We also provide each card with a smaller aperture for the passage of each of the valve-stems j', which are above the position occupied by the card when in operative position, one such aperture being `shown centrally in Fig. 2.

It will be seen that when the tube-sheet, with a card Q laid upon it, is raised into contact with the bottom of the air-chest the lower ends of the valve-Steins f f will engage the elastic packing J of the tube-sheet when the card is very close to the packing-sheet I and will, by reason of the spring-pressure and airpressure exerted upon said valves iu the compression-chamber, be forced into said elastic packing J until the card Q has been made to engage the packing I sufficiently to prevent the escape of air laterally between the parts. The further pressure of the rising` tube-plate will cause the springs g of the valves II to yield and open the valves, admitting compressed air from the compression-chamber c to the distributingchamber dx, and thus through all of the openings G in the air-chest which are not closed by solid portions of the card Q to the respective tubes B, registering therewith. The effect of this will be to depress the pistons of said tubes and the warprods and warp-threads controlled by saidpistons.

The air-chest E will be supplied with compressed air from any suitable source of power by means of a pipe S, attached to a nozzle R on the air-chest, as shown in Fig. l. The airchest will ordinarily be provided with two nozzles R, as shown, so that several machines may be connected and supplied continually with compressed air, if desired.

Ve prefer to continue the upward movement of the tube-sheet A after it has effected a connection with the air-chest, thereby lifting the air-chest bodily with it. In lowering the tube-sheet the air-chest will descend with it until it comes in contact with the brackets 7o 7s, when it will be arrested, while the tubesheet descends a little farther, thereby separating the parts at Z to permit the patterncards to be moved on and adjusted, and also to permit the tubes B, the pistons of which have been acted upon by compressed air, to exhaust and allow the pistons to be returned .by their retracting-sprin gs T. As soon as the air-chest comes to rest and the tube-sheet begins to separate therefrom the pressure on the lower ends of valve-stems f will be relieved and the valves H will instantly close, shutting off the communication between the two chambers and preventing waste of the compressed air.

In order to give the proper movements to the tube-sheet, we have shown a lifting-shaft P supported in4 the main frame of the loom and provided with lifting-cams O, which are adapted to engage the lower ends of parts connected with the tube-sheet, in this instance a pair of lifting-arms L, secured tothe tube-sheet jaws at M, and provided at their lower ends with an tifriction-rolls N to en gage the cams O.

The operation of the device is as follows: The parts beingin-the position shown in Figs.

1, 2, and 3, the lifting-arms L L resting upon the concentric portions m lm of the cams, a pattern-card is inserted between the tubesheet and the air-chest and the lifting-shaft is started, thereby raising the tube-sheet and with it all of the warp-threads b carried by the warp-rods D D. Vhen the card Q is clamped between the tube-sheet A and the air-chest E, as before described, the valves lfI will be opened and compressed air admitted to certain of the tubes B, determined by the positions of the apertures in the pattern-card, thereby depressing the pistons in said tubes and the warp-threads connected therewith. rIhe continued upward movement of the tubesheet, carrying with it the air-chest, lifts the warp-threads the pistons of which have not been operated upon, while those whose pistons have been operated upon by the compressed air are held down, thereby forming the shed, through which the shuttle isdriven. As the tube-sheet descendsthe air-chest is stopped by the brackets k 7c, the parts separate, and the pistons of the depressed warpthreads are drawn up by their springs T, thereby restoring all the warp-threads to their original positions.

The extent of the upward movement of the tube-sheet and the downward movement of the pistons in their tubes are substantially equal, and together give the warp-threads the extent of separation desired to form the shed.

What we claim, and desire to secure by Letters Patent, is-

l. In a loom, the combination with a series of cylinders disposed perpendicularly to the warp-threads, and in line therewith, of a piston in each cylinder, operatively connected directly to one of said warp-threads, means for supplying a fluid under pressure to said cylinders, and controlling devices for said fluid supply, substantially as described.
