17 Claims. (01. 2s 49) This invention relates to machines for uniting warps, and refers particularly to machines of the portable type disclosed in the Colman Patents Nos. 1,069,082, 1,082,474 and 1,149,499.

5 The general object of the invention is to make improvements in those features which relate to the handling of the warp threads preparatory to and after the actual uniting of the threads. Among the particular objects of the invention are to provide means on the main frame of the machine for so supporting the old-warp carriage that it may be conveniently supported in and outof operative position and moved from one such position to-the other; means to prevent the old-warp carriage from being accidentally or inadvertently moved into or out of its inoperative position while the mechanism carriage is out of its idle or initial position; and means for adjusting the two sheets to bring the threads thereof into parallelism.

In the accompanying drawings:

The present improvements are herein disclosed as embodied in a portable machine especially adapted to be placed behind a loom re- 45 quiring warp replenishment. That side of the machine which is toward the loom will be referred to as the loom side, and the opposite side asthe front side The end of the machine from which the uniting of the warps is started will be termed the head end, and the opposite end will be called the foot of the machine.

, The supporting framework of the machine comprises a base I mounted on wheels 2 and 3, two uprights 4 and a bed 5. As shown in Fig. 5, the uprights 4 are cut away at the loom side in order to allow the machine to be set as close as possible to the 100m. This is an advantage where the loom is close to a supporting post of the building. l-is a brake to hold the machine steady while the warps are being manipulated and tied. A handle 8" for use'in moving the machine about in the millis detachably connected to the head end of thebed, so that it maybe removed after the machine has been stationed behind the loom, thus giving the operator free access to the head end of the machine.

The warp-uniting mechanism (not shown) is mounted on a mechanism carriage that is arranged to travel on a gib 9 extending longitudinally of the bed 5. The over-all dimension or outline of the warp-uniting mechanism and its carriage is indicatedby the dotted line I0 111 Fig. 5. For a full disclosure of a form of mecha-- nism which may be used, reference may be made to the Colman Patent No. 1,082,474.

Portions of the two warps to be united are supported in the path of the warp-uniting mechanism. The supports for the new warp comprise apair of clamps ll and l2 (Figs. 5 and 6) and a ribbon bar l3 carried above the bed 5on posts M. The old warp threads are supported by a pair of clamps l5 and I6 and. a ribbon bar 'l'! which form'partsof awarp carriage designated as a whole by the number 18. 'The framework of the warp carriage includes two yokes or inverted U-shaped members I9. For a description of the clamps andthe ribbon bars reference may be made to the Colman Patent No. 1,082,474;

In order that the threads held in one pair of clamps may be brought into parallelism with those-held in the other pair of clamps, the clamps I I and ii are mounted on the ribbon bars l3 and H for. longitudinal adjustment; As shown in Fig. 6, the clamp liextends through a guide l9 and has a gib 19 that slides in a groovein the ribbon bar l'l. To one end of the clamp I5 is fixed a screw 19. An adjusting nut Ill on the'screw l9 has a peripherally grooved collar Ill that engages an abutment l9 on the ribbon; bar ll.v Turning the nut l9 -causes the clamp l5 tomove longitudinally of the ribbon bar. The

- clamp: II is similarly mounted and adjusted.

When the warp carriage is in operating position, it is supported on rollers so that it maybe moved sufiiciently to compensate for variations in the spacing of theold-warp threads and for the difference in width or spread of the two warps. In the drawings the rollers at the loom side are numbered 20 and 2| (Fig. 2); they are mountedv in bracketsattached to opposite ends PATENT of the ribbon bar |1 (Fig. 6). The rollers at the front side are numbered 22 and. 23 and are mounted in brackets fixed to opposite ends of the clamp I6 (Fig. '1). The rollers 20 and 2| run on grooved trackways 24 and 25, respectively. The roller 23 runs on a fiat trackway 26. The trackways 24, 25 and 26 may be supported from the bed- 5 in any preferred way; herein the trackways 24 and 25 are fixed to the ribbon bar I3 (Figs. 5 and 6) and the trackway 26 is fixed t0 the clamp l2 (Fig. 7).

Means is provided for supporting the warp carriage so that it may be lifted out of its operating position in order to facilitate the preparation and mounting of the warps, or in other words, the loading of the machine. Said means comprises an arm 21 which is bifurcated at one end to span the head end of the bed 5. The bifurcated end of the arm 21 is fixed upon a pivot shaft 28 (Fig. 3) which is journaled in the bed 5. Extending from the arm 21 are two parallel rods 29 (Fig. 2) which passloosely through the yokes IS. The outer ends of the rods 29 are united by a casting 30 that constitutes a handle for use in raising and lowering the warp carriage. On the arm 21 is a trackway 3| for the roller 22 (Fig. '7)

To counterbalance the weight of the warp carriage, a torsion spring 32 (Fig. 3) is placed upon the pivot shaft 28, one end of the spring bearing against the bed 5, and the other end being attached to an adjusting collar 33, the latter being fixed to the shaft by one or more set screws 34. The arm 21 is held down in operative position by means of a manually-operable latch 35 pivoted on the bed 5 at 36 and engaging a block 31 on the arm 21. The block 31 is held by the latch 35 against a bumper or stop plate 38 on the bed 5, the parts 31 and 33 serving to locate the arm 21, trackway 3| and rods 29 accurately so that the warp carriage shall rest upon the trackways 24, 25, 26 and 3| without being pressed against the trackways 24, 25 and 26 by the rods 29. There is clearance between the rods 29 and the yokes I9 when the warp carriage stands on its trackways. Rubber bumpers 39 on the bed 5 locate the arm 21 in its thrown-out position.

To prevent lifting of the warp carriage after the mechanism carriage has been advanced to its work and until the mechanism carriage has been returned. to its idle position, an interlock is provided between the mechanism carriage and the arm 21. This interlock comprises a plate 46 (Figs. 3 and 3 fastened to thearm 21 and a latch bolt 4| mounted on the bed 5, said bolt being urged by a spring 42 into engagement with the plate 4|) when the arm 21 is swung against the bumper 38. When the mechanism carriage is pushedb-ack to its initial position at the head end of the machine after. completing the union of two warps, a cam or projection 43 on said carriage engages a pin 44 on the latch bolt 4| and pulls the bolt away from the plate 40, thus leaving the arm 21 and the'warp carriage free to swing upwardly when the latch 35 is manually withdrawn by the operator. A spring buffer 45 (Fig. 2) onthe arm 21 serves to cushion the descent of the warp carriage when it slides down the rods 29 as the arm 21 rises. A similar buffer 46 is provided on the bed 5 to cushion the shock when the mechanism carriage is returned to its initial position.

Means is also provided to prevent the warp carriage l8 from being lowered in case the mechanism carriage has'been moved out of its initial position. Said means comprises the plate 40 and the latch bolt 4|. As shown in Fig. '7, the bolt 4| is adapted to lie in front of (i. e., below) the plate .40 so as to prevent the arm 21 from being swung down. The bolt 4| is beveled at 41 (Fig. 3 to coact with the lower edge of the plate 4|]. As before explained, when the mechanism carriage is in its initial position, the cam 43 holds the bolt 4| in ineffective position, so, that the warp carriage may be raised or lowered.

The operation of the apparatus herein disclosed may be summarized as follows: The machine is stationed behind the loom in position to operate upon the first group of warp threads to be tied, and held by the brake 1 against displacement. The handle 8 is removed, and the arm 21 is swung up to place the warp carriage in its out-o-f-the-way position.

After the warp threads have been secured in the clamps |2, I5 and I6 and tensioned, the threads of the two sheets are brought into parallelism by longitudinal adjustment of one or both clamps H and I5, after which the threads are deflected by operating the ribbons as described in the Colman Patent No. 1,082,474.

The mechanism carriage is then advanced into position for operation upon the threads. Such positioning ofthe mechanism carriage allows the automatic latch 4| to latch the warp carriage against upward displacement. After the portions of the warps held in the clamps have been united, the mechanism carriage is returned to its idle position, the united threads are released from the clamps H and I5, the latch 35 is disengaged and. the warp carriage swung up to the position shown in Fig. '1.

It will be seen that the warp carriage l8 can be raised or lowered only when the mechanism carriage is in its out-of-the-way or initial position, thus protecting the mechanism on the mechanism carriage from damage by the warp carriage.

While the present invention has been described in connection with a portable machine, it will be understood that certain features of the invention may be applicable to stationary machines. It will also be understood that various changes may be made inthe construction herein disclosed without departing from the scope of the invention as defined in the appended claims.
