T 0 all whom it may concern:

Be it known that I, HowAnn D. CoLMAN, a citizen of theUnited States, residing at Rockford, in the county of IVinnebago and.

State of Illinois, have invented certain new and useful Improvements in Textile Apparatus, of which the following is a specification. i i

This invention relates to an improved means for presenting textile elements and loom elements, as, for example, warps, loom harnesses and loom reeds, to an operating mechanism. In the present embodiment the invention is illustrated as applied to amachine for drawing warp threads through harnesses and reeds.

The object of the invention, generally stated, is to economize the time of textile machines, as for instance, warp-drawing machines. It is always desirable to make the output of a machine as large as possible, and this is especially true when the machine is expensive, as in the case of a warp-drawing machine Obviously one method of increasing the output of a machine is to keep it in operation as nearly continuously as possible.

A considerable amount of time is necessarily expended in arranging a warp, a set of harnesses and a reed for presentation to a warp-drawing machine. During the inter- "als between its operation upon successive sets of elements, the machine, as heretofore arranged, has necessarily been idle, and it v on. the warp carriage.

Fig. 10 illustrates a device adapted to be removably connected to the warp carriage.

The warp-drawing machine may be of any I have herein illustrated a machine substantially similar to the one illustrated in Patent No. 1,115,399, dated October 27, 1914, to which patent reference may be had for a detailed description of the machine.

The warp-drawing machine herein shown comprises a bed A supported upon legs A. The drive shaft A is rotatably mounted in suitable bearings upon the bed A, and has at its outer end a tight pulley A and a loose pulley A Driven from the shaft A in a suitable manner is a rock shaft A alined with and drivinga screw-threaded shaft B for feeding the warp-supporting carriage.

At the rear side of the bed are two upwardly-extending arms A which carry a fixed guide rail A extending throughout 'but showing the warp as completely drawn the length of the machine. Said rail supports the carriages for the harnesses and the reeds. In the upper edge of the rail A is a groove A, (Fig. 5), and in the lower edge of the rail is a rabbet or guideway A.

The parts thus far described are similar to those shown in the said patent. The bed A of the present machine, however, has been made longer at the head end or receiving end of the machine, and the harnesscarriage-supporting rail A and the warpcarriage-supporting and feeding shaft 'B have been correspondingly lengthened.

The operating mechanism is indicated d1- agrammatically at D in Fig. 1.

The warp-drawing machine comprises a plurality of carriages for warps and a plurality of carriages for harnesses and reeds, preferably two warp carriages and two har ness and reed carriages being provided. Each harness and reed carriage may, if desired, be identical in construction with the one illustrated in the said patent and as herein shown. It comprises end frames (1 (Fig. 7 and two upper connecting rods Q G the harnesses being supported from sald rods, as indicated in Figs 7 and 8. The harness and reed carriage is provided with rollers C adapted to run in the groove A of the rail A and other rollers C adapted to run in the guideway A in said rail.

The warp carriages may be of any suitable form, as for instance, that illustrated in the before-mentioned patent, and as shown herein. Each of said carriages consists, in this instance, of a framework B having a warp clamp B (Fig. 3) at its upper edge and a warp clamp B at its lower edge. In order that the warp threads may be placed under tension after they have been secured in the clamps B and B the clamp B is pivoted to the framework B at B and is swung away from the clamp B by means of links B a rock shaft 13 and hand levers B,

V as indicated in Fig. 1 herein and as fully illustrated and described in said patent. Said hand levers have been omitted from Figs. 2 to 6. The carriage is arranged to be slidably supported upon the screw-threaded feed shaft B and the rock shaft A by means of feet 13*, which feet are not screwthreaded. At the rear end of each warp carriage is a half nut B (Fig. 1) adapted to engage with the feed shaft B, said nut being arranged to be thrown into and out of engagement with the screw shaft in any suitable manner, as, for example, that illustrated and described in said patent.

WVhile a warp is being operated upon by the mechanism D, the carriage containing the warp stands upon the screw shaft B and the rock shaft A the carriage being supported in a substantially upright posi tion by reason of the fact that the portion C (Fig. &) of said carriage rests against a stationary portion A upon the warp-drawing machine.

In the operation of the warpdrawing machine, the threads supported in a carriage B are drawn through the eyes of harnesses and the spaces.of a reed supported in a harness and reed carriage C, said carriages traveling past the operating mechanism. A carriage B and a carriage C will be hereinafter termed, for convenience, a set of carriages. For use in handling each set of carriages there is provided a truck 1 which may be of any suitable form. It is herein shown as comprising two sills 2 and two uprights or standards 8 rigidly connected together by means of bars 4: and pieces 5. The parts 2, 4, and 5 constitute a base, at the side of which the standards 3 are located. The base is mounted upon casters 6 so that it may be moved into and out of operative relation with the warp-drawing machine, and so that it may be traversed alongside said machine. The rear ends of the sills 2 have fixed thereto stops, alining devices or distance members 7 (Figs. 4; and 49 arranged to. lie against a shaft 8 supported in the warp-drawing machine frame near the floor and extending longitudinally of said machine. Said shaft may be driven in any suitable way, as, for instance, by means of a belt 9 running over a pulley 10 on the shaft A and a pulley 11 on a stub shaft 12, the latter shaft carrying a pinion 13 which meshes with a spur gear wheel l i on the shaft 8. The shaft 8 is screw-threaded throughout the greater portion of its length.

Upon one of the sills 2 is pivoted an arm 15 carrying a half-nut 16 which is adapted to engage the screw-threaded shaft 8 for moving the truck 1 longitudinally of the warp-drawing machine. The arm 15 may have a rearward extension carrying a foot piece 17 for convenience in throwing the half-nut into and out of operative position.

Upon the forward side of the truck 1 is a bar 18 upon which is mounted a pair of posts 19 for supporting the journals of a loom beam (1. These posts are omitted from Fig. Preferably the posts 19 are adjustable in position to accommodate beams of different lengths. They are herein shown as slotted and as being clamped in adjusted position on the bar 18 by clamping bolts 20.

Two arms 21 and 22 are pivoted upon the uprights 3 to swing in a vertical plane. The arm 22 has a notch 23 (Fig. 3) in its outer end to receive a projection 24 upon one end of a warp carriage B. The other arm is also arranged to support one end of a warp carriage and is provided with suitable means for preventing undesired movement of the frame with relation to the arms 21 and 22. In this instance, an annular clamp 25 is provided upon the outer end of the arm-21 and within said clamp ismounted a disk 26 having a non-circular opening 27 therein to receive a correspondingly shaped projection 28 upon one end of the warp carriage. The annular clamp 25 may be tightened'by means of a screw 29 to frictionally clamp the disk 26 so that while the warp carriage may be turned by the operator it shall be held against gravitational movement.

The arms 21 and 22 are arranged to be swung by means of hand levers 30 pivoted upon the uprights 3 and connected to said arms by means of links 31, said links having a pin and slot connection with the arms. 32

vare pins-for limiting the pivotal movement of the hand levers 30 in one direction. The pivotal movement of said hand levers in the opposite direction is limited by the engagement of the links 31 with the pivotal supports of the hand levers, as shown in Fig. 2. The hand levers 30 are fixed upon a rock shaft 33 (Fig. 1). so as to move together.

For holding. the sheet of warp threads up out of the way of the operator so that he may have access to the forward side of the warp-drawing machine, I provide a guide or cross bar carried by arms 35 which arepivot-ed at 36 to the upper ends of the uprights 3. The arms 35 are extended below their pivots, and to theseextended ends are connected coiled tension springs 37 which tend to hold the cross bar in either of the two positions shown in Figs. 2 and 4. 38 is a stop pin for limiting pivotal movement of the arms 35 in one direction. The warpsupport'or guide 34 '35 has been omitted.

from Fig. 1 in the interest. of clearne ss,

To prevent undesired rotation of. the loom beam at, suitable means may be provided, as, for example, a bar 39 arranged to be laid across a rod 40 fixed in the truck frame. See Fig. 2. One end of the bar 39 is bent into suitable form to contact the gear teeth upon the beam, and the other end of said bar is adapted to be depressed by the foot of theoperator to press the brake end of the bar against said teeth. When the brake is no longer needed the bar 39 is withdrawn.

Fixed upon the upper part of each warp carriage B- are two notched brackets 41 for supporting the harnessand reed carriage, the latter having pins C (Figs. 6 and 8) adapted to rest upon said brackets, as will appear hereinaften A pair of curved fingers 42 (Figs. 5 and 10) are arranged to be removably connected with the upper end of each warp carrlage. The connecting means may be of any suitable character; for example, the fingers may have hooked or bent ends 43 to enter sockets 44 on the upper bar of the warp carriage. Said fingers are of sufiicient length to-support the bars 0 C of a harness and reed carriage, as will appear more fully hereinafter.

One method of using the apparatus hereindisclosed will now bedescribed:

Fig. 2 shows a truck 1 with its parts in position for the commencement of the loading operation. -The cross bar or guide 34 is down, and thearms 21 22 arein their low ered position, with a warp carriage B in place on said arms, and in inverted position. A loom beam a having a new warp b thereon is placed upon the support 19, the free end of the warp being held in a clamp of anycommon or preferred construction, such as an ordinary plush clamp 0. The warp is then carried over the guide 34 and the clamp B of the warp carriage B, as shown in Fig. 2. After carrying the warp over the clamp B the operator prevents the warpbeam from I revolving by means of the foot brake lever 39 while pulling the warp into'a smooth even sheet, the threads slipping through the plush clamp c as tension is placed upon them. The warp is then secured in the clamp 13*, and the warp carriage B rotated upon its supports in the arms 21 and 22 in tion of the sheet' extending between the clamps B and B is stretched or tensioned by means of one of the hand-levers "B? as explained in the patent hereinbefore re- 2 ferred to. The warp support 34 may then be swung up into its operative position. The

warp carriage is now ready to be placed upon its supports in the warp-drawing machme, but before that 1s done a harness and reed carnage C containing harnesses and a reed is placed upon the-head end of the rail" A and moved into operative relation with the mechanisml), the sides of the eye-spacer mechanism having been separated to admit the carriage C, as described in-the beforementioned patent. In placing the warp carriage B on the warp-drawing machine, the operator raises one of the hand levers 30 into the position shown in Fig. 5, thereby raising the warp carriage to the height indi-- cated in said figure. The truck is then pushed up to the warp-drawing machine and the hand lever lowered into the position shown in dotted lines in Fig. 4, thereby lowering the warp carriage B onto its supports in the machine, the warp carriage B then being nearly opposite-Orin front of the harness and reed carriage O. The warp carriage B being arranged to be sensitively fed by the shaft B, it is necessary to disconnect the truck 1 from the warp carriage, which is accomplished by lifting the projection 24 out of the notch 23 in the arm 22 and drawing the projection 28 out of the opening 27. The arms 21 and 22 are thereupon swung up out of the way, as shown in full lines in Fig. 4. The lateral tension or deflection is put upon the threads as described in the before-mentioned patent, the Warp carriage is advanced by the operator until the first warp thread is near the selector, the half-nut 16 on'the truck is thrown into engagement with the screw shaft 8, and the half-nut B on the warp carriage is placed in engagement with the screw shaft B. The warp-drawing machine being placed in operation, the harness and reed carriage C and the warp carriage B are fed past the operating mechanism, and the truck 1 is moved along the front of the machine by means of the screw threaded shaft 8 engaging the half-nut 16.

While the machine is operating upon the warp, harnesses and reed contained in the set of carriages just referred to, another set of carriages B and C is loaded.

When the first warp has been drawn in, the machine stops. The operator then opens up the eye-spacer mechanism, disengages the half-nut 16 from the feed shaft 8, and pushes the harness and reed carriage and the warp carriage forward along the machine until said carriages are clear of the operating mechanism D, the operator steadying the warp carriage after the latter has passed the ledge A The operator then lowers the arms,

21 and 22 and engages said arms with the projections 24 and 28 on the warp carriage; lowers the clamp B by means of one of the hand levers 13; places the hooks 42 in the sockets 44 and swings said hooks under the top bar C of the carriage C; operates the hand lever 30 to withdraw the warp carriage and the harness and reed carriage from the warp-drawing machine, as shown in Fig. 5, and then rolls the truck, bearing the drawnin warp, the harness and reed carriage and the warp carriage, away from the warpdrawing machine. The operator then places the second set of carriages and the second truck in operative relation to the machine, and sets the latter in operation. The first harness and reed carriage is then lifted off the fingers 42 and suspended on the supports 41 on the warp carriage, so as to provide slack in the threads between the clamp 13 on the one hand and the harnesses and the reed on the other, and to bring the harness eyes into approximately a plane with the clamp B as shown in Fig. 7. The thread ends projecting through the reed are then drawn up and tied in small bunches, the fact that the harness eyes are approximately in a plane with the warp clamp 13 enabling the operator to draw the threads up to substantially the same length. The clamp B may now be opened to release the warp. The carriage C is next removed from the harnesses and the reed, leaving the harnesses and the reed hanging on the warp; the Warp carriage is lowered by means of one of the hand levers 30 into its lowest position; the beam is revolved to draw the harnesses and the reed up to the guide 34; and then while continuing to revolve the beam the operator swings the guide 34 down into inoperative position, the rotation of the beam keeping the warp taut so that the threads shall be wound parallel on the beam; the harness and the reed are laid on the beam and tied to it; and the beam removed from the truck. The first truck is now ready to be used in placing another warp in the Warp carriage on said truck.

It will be seen that while the machine is operating upon the second warp, the operator is getting the drawn-in warp ready to be sent to the weave room, and is preparing a third warp and third set of harnesses and reed for reception in the warp-drawing machine. The machine may be kept in operation substantially all of the time, thereby greatly increasing its output.

It will be understood that while I have described the apparatus as embodied in a warp-drawing system, the broad features thereof are applicable'to a warp-tying apparatus. It will also be understood that the invention herein described is applicable to warp-drawing machines of other forms than that herein alluded to, and that various changes may be made in the truck and associated apparatus without departing from the spirit of the invention.
