PETER J. HINDS AND EDGAR S. FERRIS, OF I-IOLYOKE, MASSACHUSETTS.

IDOFFING-WIRE.

' To all whom it may concern.

Be it known that we, PETER J. HINns and EDGAR S. Foams, both citizens of the United States of America, residing at Holyoke, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Dofiing-VVires, of which the following is a specification.

This invention is designed to facilitate the operation of doifing the filled bobbins on a spinning frame and replacing them with empty bobbins, and is an improvement upon the dofiing wire of our prior Patent No. 1,000,909, issued August 15, 1911.

Before removing" the filled bobbins or cops, it is necessary to swing the thread leading to each spindle out of the way of the operator, and prior to the .invention shown in our said patent such movement of the threads was done by hand. By the means shown in our patent, however, an operator at each end of the spinning frame raised-a wheeled carriage, mounted on a track secured to the front of the upright supports at each end of the frame, practically as high as the top of the bobbins, then swung arms pivoted to the said carriages,

over the bobbins, and the dofiing wire car-.

'ried by said arms engaged all the threads at once and swung them away from their respective spindles as the arms were moved back of the spindles and the carriages dropped to their lowered position.

By our present improvement, a much simpler and more economical construction of doiiin device is provided, and while the prior do ng wire required that the operator employ both hands in the two movements of first raising the carriage and then swinging the arm carrying the wire over the spindles in order to operate the device. our

present invention enables this operation to be accomplished by a single movement and by one hand of the operator.

To this end,'an important feature of the invention comprises means whereby an arm or carrier for thedofling wire is pivotally secured to a single fixed point on the upright support at the end of a spinning frame and is arranged to be vertically movable relatively to such support; said arm being both vertically and pivotally movable.

A very important advantage of the present improvement is that by reason of Specification of Letters Patent.

the simple and li ht construction of the carriers for the do%ng device, practically all danger of breaking the threads leading to each spindle is eliminated, whereas in the device of our prior patent the extra weight of the traveling wheeled carriages was apt to break the threads 'when thecarriages were dropped by a careless operative and the dotting wire was in engagement with the threads.

Further objects of the invention are to provide a doliing device which may be easily and quickly attached to spinning frames, which cannot easily get out of order, and which will have capacity for greatly increased specd of operation.

Referring to the drawings, wherein a pro ferred embodiment of the invention is illustrated, Figure l is a front view of a portion of a spinning frame with the dofiing device mounted on each end support; and Fig. 2 is a view, partly in cross section, on "the line 2-2 of Fig. 1, looking toward the right;

The usual spinning-frame construction comprises upright supports a, a at either end, a bolster m on which the spindles b are mounted, and a vertically movable ringrail 6, all being arranged in the usual and well known manner.

attached to the spinningbframc. On each y suitable screws,

the height of the ring-rail 0 when said ringrail is in its lowered position. A block f is pivotally secured to the upstanding portion of the member n by means of a bolt is, said block 7 being suitably bored to receive a sliding carriage or arm g. This arm g has at its upper portion a'turnbuckle h threaded therethrough, and at its lower portion a head or flange to limit its upward movement. The turnbuckle h has an eye in which the end ortion of the doffing wire 6 is secured. uplicate sliding arms or carriages gare similarly arrang dto each support, and the wire 0 is adjustably secured thereto, as will be readily understood Our dotting device is filled, the spinning is'sto'pped, with the ringrall in its lowered position. Operators at each end of the spinning frame manually grasp and lift the respective arms 9, slldingthem upwardly in the blocks f until the wire a may be swung over the tops of the spindles b and against the threads '0 leading to I and empty ones replaced, when the sliding ing while v eration;

. uprightsupports,

mods g are operated ina reverse manner to swing the dofiing wire 6 from the position shown in Fig. 2 back to that as shown in Fig. 1, when the spinning may be resumed.

It will be readily seen that we have provided a doffing device of the utmost simlicity of construction and one which may e operated with great ease and facility,

the operator lifting and swinging a rod 9 to position the dofling wire 6 in either operative or inoperative position by a single movement and with only one hand. Also the light weightof the entire movable portion of the dofiing device renders dama e to or breakage of the threads unlikely. guch lightweight also minimizes the labor of do-fipermitting increased speed in op- In the device of our prior patent it was necessary to use a track on which the wheeled carriage could be raised and low ered, and if said track was bent, either by accident or by the tension of the dofling wire, the operation of the carriage was difiicult, whereas in our present improvement, by affixing the block 1 by means of a'strong pivotal connection at a fixed point on the any likelihood of derangement of the moving members or difiiculty in their operation is eliminated.

Another advantage of considerable practical importance inthe device of our present invention is that it may be applied to a" spinning framewith great ease and rapidity, necessitating merely the affixing of the members 7], to the front of the frame, where as the device of our prior patent required the afiixing, adjustment and truing of parallel tracks on which the wheeled carriages traveled.

Having described our invention, what we spinning frame,

-spinning frame claim as new and desire secure by Letters Patent is:

1. In combination with the spindles of a spinning frame, a dotting device comprising a wire supported by two carriers, each carrier being pivotally mounted on an end suping provision for vertical sliding movement relatively with said support, whereby the wire can be moved from a position in front of the'spindles over the tops of the spindles to engage the threads leading thereto by a simultaneous vertical and pivotal movement. 2. In combination with the spindles of a a dofling device comprising two arms pivotally mounted at fixed points on the frame, said arms being constructed and arranged for sliding movement relatively with said. pivotal connection, a wire carried by said arms, and adjustable means to connect an end of the wire to each arm.

3 In combination with the spindles of a spinning. frame, a dofling device, comprising a wire carried by means mounted on the at a fixed point, which means have provision for simultaneous vertical and pivotal movement relatively with said frame to cause said wire to engage the thread leading to each spindle and to hold said threads away from said spindles.

4. In combination with the spindles of a spinning frame, two separated fixed supports, a holding device pivoted to each support, a rod held by and movable relatively to each holding device, a wire subtended between said rods whereby said rods may be moved to position said wire in front of, or behind the spindles, and in either position to move the wire lengthwise of the spindles.

5. In combination with the spindles of a spinning frame, two separated supports, a holding device pivoted to each support, a rod held by and movable longitudinally with respect to each holding device, a wire subtended between said rods whereby said rods may be moved to position said wire in front of, or behind the spindles, and in either posit-'on to move the wire lengthwise of the spindles.
