AND R. N. WOODWORTH, OF NEW YORK, N.

IMPROVEMENT IN THREAD DRESSING AND WINDING MACHINES.

Specification forming part of Letters Patent No. 139,521, dated J une 3, 1873; application filed December 31, 1872.

To all whom it may concern:

Be it known that I, JAMES SHORT, of New Brunswick, in the county of Middlesex and State of New Jersey, have invented a new and Improved Thread Dressing or Winding Machine, of which the following is a specification:

Figure 1 is an end elevation of my improved thread dressing or winding machine.

1 Fig. 2. is a side elevation of the same, and

Fig. 3 a detail top view, partly in section, of a portion of the same.

Similar letters of reference indicate corresponding parts.

The object of my invention is to furnish to thread manufacturers an improved threadwinding machine; and it consists in a certain construction and arrangement for facilitating the connection of the axle of the spool or thread-beam with the driving-shaft and its removal from the machine; in the provision for ready connection and disconnection of the weighted arms from those carrying frictionrollers and co-actin g with a loose thread-pressing roller, as hereinafter fully described.

In the accompanying drawing, the letter A represents the frame of my improved winding machine or winding attachment to a thread-dressing machine. This frame is made of metal, wood, or both, of proper size and strength to support the parts of the machine pertaining to this invention. B is the beam or spool around which the thread is to be wound. This beam is made hollow to receive a prismatic shaft, 0, which hangs with its rounded portions that are formed near its ends, in the notched upper parts of standards a b of the frame A. One extreme end, d, of this shaft 0 is squared and fits intoa square mortise, 6, formed in the end of the shaft D, by which motion is conveyed to said shaft 0, and thereby also to the beam B that surrounds it. The mortise in the end of the shaft D is open at one side, and whenever the open portion is brought in line with the notches in the standards a b, the shaft 0 with its beams, can be drawn forward and down the inclined surface .1? of the standards until the beam or roll rests on the floor, (or other support provided for it,) when the shaft can be withdrawn provided with projecting arms F F, whose rounded ends carry friction-rollers f f. G is a roller of suitable size, weight, and material, and about as long as the beam B between its flanges, and is placed upon the beam and bei'ieath the friction-rollers f, of the arms F, as is fully indicated in Fig. 2. H H are other arms projecting from the spindle E, and provided with weights I I, which weights serve to draw the arms F upon the roller G, and press the latter uponthe beam B.

V When thread is being wound upon thebeam, the beam is revolved in the direction of the arrow 1, Fig. 2, and atthe same time the roller G will be revolved in the direction of the arrow 2 of the same figure, and will thereby tend to retard the application of the thread---. that is to say, prevent the loose winding of the same. The weights I at the sametime serve to press the roller Gdown upon the thread, allowing it, however, to be crowded gpward gradually by the thread that accumulates on the beam; and thus to be moved from the lower position, in which it is shown by dotted lines in Fig. 2, into the upper position dotted into the same figure.

In practice, I provide an automatic apparatus for stopping the machine when the threadbeam or spool is filled, and simultaneously supporting the arms H so that the pins 9 may be removed. The friction-rollers ff facilitate the rotation of the roller G, and make the use of lubricating material unnecessary. I secure the arms H H upon the spindleE by means of removable pins or bolts 9, to enable I the arms F to be swung quite back clear of the beam, when it is necessary to remove the same, or else the arms F may be secured to the spindle E by such removable pins. The weights I may be made adjustable on the arms H, so that, by setting 'them, their effect on the roller G maybe regulated. The machine may be made with but one arm F, and

2. The arms F, carrying friction-rollers f, and fixed on the shaft E, in combination with I the Weighted arms H mounted loosely on the -rojecting ends of the shaft, and removable pins 9 for locking said parts together, in combination with the roller G and beam B, arranged as shown and descrlbed, for the purpose specified. 1

3, The combination with the spoolB mounted on a removable spindle, the roller G placed above and resting on the spool and prevented from longitudinal movement by the flanges or disks of the spool, of the hinged arms F, provided with friction-rollers that bear on the body of the roller, and are retained against said rollers at all times by the weighted arms, as and for the purpose described.
