WARP-REPLENISHING MACHINE.

- Specification of Letters Patent.

Application filled October 30, 1911. Serial No. 657,828.

To all whom it may concern:

Be it known that we, EDGAR F; HATHA- WAY and CHARLES LEA, both citizens of the United States, and residents of Boston, county of Suffolk, Commonwealth. of Massachusetts, (whose post-oifice addresses are 195 Freeport street, Dorchester, Massachusetts,) have invented an Improvement 1n Warp-Replenishing Machines, of whloh the following descriptlon, in connection w1th the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention :relates to improvements in warp replenishing machine, and has partlcular reference to apparatus for facilltatlng the preparation of warps for installation 1n the loom.

Preferably the apparatus is in the form of a transfer device, for usein con unct1on with warp drawing-in machines, such device being adapted to load or unload the machine with the warp, harnesses or other loom elements employed, and being of such a nature as to increase the capacity and output of such machines, and facilitate the work,

of drawing-in the warps thereon.

The invention will be best understood by referenc to the following description when taken in connection with the accompany-.

ing illustration of one specific embodiment thereof, while its scope will be more partic-- ularly pointed out in the appended claims.

In the drawings: 7

Figure 1 is a side elevation showing a transfer device with the'warp beam, harnesses and reed'in position for installation in a warp drawing machine;

Fig. 3 is .a detail of the reed holder;

Fig. 4 is a detail in partial section showingthe connection between the harness bar.

and its support; and s Fig. 5 is aplan view of the'bracket or holder for the harness bar support.

Referring to the drawings and to the embodiment of the invention by which I have therein illustrated the same, there is shown one form of transfer device cooperatively associated by way of example with a well known type of drawing-in machine 1, the latter being of the same general construction as that shown in U. S. Patents Nos. 755,861, to Field; 871,860 to Field at al.,' 862,474 to subsequently made.

Hathaway and Blanchard. Such machine.

is herein shown for the sake ofillustration, it being obvious. that the transfer device described with suitable modification may be usefully employed with-wa drawing and gather machines of widely different construc- In the illustrated form of machine, as is well" known to those skilled in the art, the loom elements, that is to say, the warp threads and those elements such nesses, reed and drop wires, which accompany and are associated with the. drawn-in warp for the control thereof in the loom, are supported in a generally parallel arrangement lengthwise the machine, while an appropriate needle or other thread placin device carried by a traveling carriage o the machine is caused to traverse the extent of the reed and harnesses and place successlv'e warp. threads through the desired heddle eyes and the'selected reed dents, these being appropriately positioned for thatpurpose in the needle path by suitable selecting and positioning mechanisms.

he purpose of the invention is to provide a transfer device whereon the loom elements, such as the harnesses, reed and drop wires, which accompany and are associated with the drawn warp for the control thereofin the loom, may be supported in substantially the position which the elements are designed to occupy in the drawing-in machine, so that they may be installed therein on the said transfer device or may be withdrawn therefrom and maintained in such osition or relation on the transfer device w ile examination for and correction of errors is is to provide a transfer device of such simplicity as to be inexpensive in construction and at the time capable of being collapsed or .moved out of the way while not in use orduring the drawing-in operation, so that while the transfer device still holds the warp beam there-may be otherwise left a freeunobstructed space for the machine operator.

Referring to the particular type of trans for device illustrated, the latter comprises a frame or platform consisting of. the parallel channel irons 2 connected together and supported at each end upon pairs of swiveled trucks or casters 3. At one end there is provided a fixed upright bracket or standard 4 V Patented May 27, 1919. V

as the har- The object furthermoreand near the opposite-end a similar bracket 5, the latter, however, being. longitudinally.

adjustable between the channel irons 2.

Each standard has fixed therein an upright bar 6 which through intermediate de- "vices su ort the reed, harnesses and drop wires. 8% support the warp beam, eac

. bracket is also provided with 'a war beam holder consistin of a block having the 10 vertical stefir 8 tting a socket in the standard and. adjustable vertically to different heights therein by means of the set screw 9.

The block '7- has attached thereto the L-shaped member 10, to the upright arm of which are fastened the jaw teeth 11 and on the horizontalarm of which rests the supporting block 12 having inclined sides. The

warp beam rests between the inclined'block 12 and the jawteethll, being held by its ow-n'weight from-turningin such a direction a as to permit unwinding of the war threads.

The upper side of the member 10 is toothedbe required to turn the warp beam to slack 85 the threads somewhat and-to permit this to be-readily accomplished, means are provided for lifting the warp beam free from the restraining influence of the jaw teeth 11. For this purpose a lifting lever 15 is provided pivoted at 16 on the holder, the end of the lever underlying the end of the warp beam and permitting the operator readily to lift the same. A fixed'pin 16 on the holder working; between projections on the lever limits both the up and down movement of the latter.

Referring to the devices for supporting the remaining loom elements, on each upright-support 6 there is rovided a verti- 'cally ad ustable bracket 1 havin upr ght ears or lugs 18 (see Figs. 2 and 5% between which is pivoted the horizontal supporting bar 19, the bracket 17 having an extension to' provide an underlying rest 20 for the bar 19 so that the latter may be swung to a horizontal position where it is supported by the rest 20 as represented at the right hand side of Fig. 2, or swung up and back through approximately 270 where it hangs down at the side of and parallel with the bar 6 as shown at the left hand side of Fig. 2. The bars 19 serve as collapsible, inturned, horizontal, loom-element supports being directed inwardly over the warp beam when in position, but being'adapted to be swung out of the way into the collapsed position leaving the space intermediate the upright bars 6 substantially unobstructed by the harness and other supports. To support the harness barsfdrop wires and reed, 'harness-supporting bars 21 are provided so connected to the inturned supports 19- as to be adjustable thereon at right angles thereto as represented in Fig. 1, or to be swunginto parallelism therewith andhang down at the side 7 5 of the bar 6 as re resented at the left hand side of Fig. 2 w en the supports are 001- \lapsed.

A simple but effective connection between the

bars

19 and 21 is shown in detail in Fig. 4. This consists of a thiinble or cup 22 transversely slotted at 23 to receive the bar 21 and having a bottom forated to receive the stud 24, the latter aving thehead 25 which seats in the bottom of the cup. The

stud 24 in turn is slotted to receive the bar 19 and the end'of the stud is threaded to receive the threaded nut 26 which is therefore adapted to be screwed upon the stud against the lower edge of the bar 19. The head 25 of the stud is drilled to forma socket for the sliding-pin 27, which latter is interposed between .the-upper edge of 'thebar 19 and the lower edge of the bar 21. When the nut26 istightened it clamps the

bars

21 and 19 with the intervening pin 27 tightly between. the cap 22 and thenut 2 6'. When the nut is loosened the connection is free to be slid along either bar in either direction and the bars are free to be swung-to any required angle witheach other or to a position of arallelismas shown at the left in Fig. 2. he donnection between the bars therefore can be made at any position in the length of either one and they maybe adjusted to any required angle permitting a universal adjustment'to beobtainedwith a single connection, which, however, can be clamped fast with the single nut 26.

To support the reed a simple form of-reed holder is provided, the same consisting of a notched portion 28 at the end of each rod 21' of sufiicient size to receive the 'upper reed Shaft. I I 5 The opening 28 is closed by means ofa sliding pin or stud 29. "which is normally pressed out to the position shown in Fig. 3 by means of the spring '30. By merely pressing the reed shaft up a ainst the head of the stud 29, the latter is li ed to allow the reed shaft to move into the dotted line position therein shown. To release the reed it is merely necessary to press the stud 29 up against the spr1ng30.

' To support the drop bars, notches 31 are provided on the under side of each harness supportingbar 21, thereby. providing shoulders on w ich may be carried the stringer rods for the drop wires.

In utilizing the machine as a loading device the two supporting bars are swun up into the position shown at the right of i 2 and adjusted to the required height, ang e and position. The upper shafts of the harnesses are. then laid across the harness supporting bars 21 in the relation they are intended to occupy in the drawing-in machine, the reed is placed in its holder and the drop wires, if any are employed, are also placed in position by inserting their hanger bars n the notches 31. With the warp beam 1n position the transfer frame is then moved to a position at the rear of the warp drawing machine, as represented in Fig. 1, br1nging the harnesses, reed and drop bars 1n substantial registration with their holding devices in the warp drawing machine. The reed, harnesses and drop wires, being thereupon transferred to their supports in the machine, the nuts 26 can be loosened permitting the arms 21 to be slipped back and then with the arms 19 to be swung down at the side of the bars 6 as shown at the left in Fig. 2. The warp threads being then in stalled in the machine, the drawing-in operation can proceed, there being no supporting parts carried by the truck to interfere with the machine operator.

To unload the warp drawing-in machine, the operation is reversed, the rods 21 being moved to the position shown in Fig. 1 and the reed, harnesses and drop wires being again attached thereto carrying the drawn in warp.

In this position the parts are withdrawn from the machine permitting needed correc tion of errors to be made apart from the warp drawing-in machine, while the latter may be employed for drawing in a second warp.

If required, a supporting rod 32, carried by the vertically ad ustable brackets 33 on the upright bar 6, may be employed to support the clamped ends of the warp threads and prevent them from falling down during the installation of the warp in the warp frame or holder of the machine.

While for purposes of illustration we have herein shown and described one form of the invention, it is to be understood that the same is not limited to details of construction or the relative arrangement of parts, but that extensive deviations may be made therefrom without departing from the spirit thereof.
