CORPORATION OF RHODE ISLAND WARP BEAM VJINDING MACHINE Application filed April 18,

This invention relates to a warp beam winding machine, and has for its object to provide a drive for the beam which will not damage the yarn and which will be more positive than driving the beam through engagement with the yarn itself, especially where silk or rayon having a smooth shiny surface is operated on.

Another object of the invention is to provide a drive for a warp beam which will enable the operator to more easily locate and piece together a broken end.

Another object of this invention is the provision of a construction which will permit the warp beam to be easily handled and mounted in the machine or removed from the machine and yet rigidly secure the bearings for the warp beam when in operating position to prevent vibration. v

A. further object of the invention is the provision of means cooperating with the drive of the machine to vary the driving speed of the machine that the linear travel of the warp threads about the beamxwill remain substantially constant regardless of the increased diameter of the beam as the winding accumulates thereon.

A still further object of the invention is the automatic compensation of such varia tion in the speed of the drive which is operated by connection with the driving means itself.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings Fig. 1 is a side elevation of the machine, illustrating the warp beam in driving position.

Fig. 2 is an end view of the structure shown in Fig. 1.

Fig. 3 is a fragmental view showing the position of the warp beam as onthe floor or support for the machine with the arms secured to the hearings in its lowered position.

Fig. 5 is a detailed view illustrating the control for the automatic compensating means for varying the speed of the power roll.

In warp beam winding machines it is usual practice to drive the beam by engagement with the work itself in order that a constant linear travel of the warps may be had and when the work is stopped prior to completely filling the warp beam and the drive is picked up or started for a completion of the winding of the warps, I have found that such drive sometimes damages the yarn and when used upon warps having a shiny sur-. face, such as silk or rayon, is apt to slip along the yarn as sufficient pressure cannot be applied to stop this and consequently there will be a certain amount of lost motion and damaged yarn. I have also found that in removing warp beams from the winding machine, as the same may weigh in the neighborhood of five hundred pounds filled, that these beams are diflicult and awkward to handle, and in order to avoid these 1111- desirable results and conditions above mentioned, I have driven the warp beam from the head thereof throughout its operation in the machine and compensated in the drive to secure a constant linear speed for the warps at a maximum speed at which the warps may be run, and I have also provided a mounting for the warp beam which permits it to be lowered after filled with yarn to the floor or support for the machine to be there disconnected from its bearings and rolled away to some convenient place for-- handling, and by this arrangement I per m1t a new warp beam to be positioned in its bearings while resting onthe floor and then raised to its driving position and heldsecurely in this position, the raising being accomplished by guiding .means which .en

gagethe head of the warp beam andportions attached to the arms; and the following 'is a detailed description of the present embodiment of this invention illustrating the preferred means by which these advantageous results may be accomplished.

"the b of this power roll With reference to the drawings, designates a frame standard of the machine which is provided with feet 11 to rest upon the floor or other convenient support 12. Two such standards 10 are provided and between these standards there extends suitable braces for maintaining them in position, and along the upper edge of the machine there is provided a guide roll 13 over which the warps 14 are guided to the warp beam which is designated generally 15 and which consists of opposite heads 16 at the ends of a barrel portion 17.

Arms 18 are provided at each side of the machine which have bearings 19 at their ends with a separable cap portion 20 to be removed for mounting 0r dismounting a warp beam to or from position, the same being provided with an axle 21 in said bear These arms are connected at their upper ends to a lever 22 which is keyed to the shaft 23 and which is rotated by means of a worm wheel 24 and worm 25 by a suitable crank 26 having a handle 27.

As illustrated in Fig. 3, the beam is in position on the floor and the arm is in lowered position with the axle 21 mounted in the bearing 19. Upon turning the. crank handle 27 to operate the gears 24 and levers 22, the arms 18 are drawn upwardly and swung outwardly by reason of the heads 16 of the beam engaging the guide and brace rod 28 extending. between opposite frame supports 10 of the machine.

vertically while rolling about the guide 28 and is so positioned that the pins 29 on the arms will be guided into a position to engage the cam surfaces 30, as illustrated in dotted lines at 31 and thence as the arms 18 are drawn upwardly the pins 29 will move into the sockets 32 provided for them on the frame of the machine and maintain the arms in a firm relation to the machine,

and rigidly rotatably mount the beam in its driving bration.

The sole driving means for the beam in my present machine is through the heads of eam by some resilient means and to accomplish this I have provided an elongated power roll 33 which is driven from a suitable source of power by a pulley 34; I mount arms 35 to pivot about the axis '36 position to prevent chattering or viouter end of these arms are resiliently supported rubber surfaced drive rolls 37 allowing some yield and held in engagement with the power roll 33 by means of a spring 38.

These rolls are mounted in suitable bearings in the ends of the arms 35 by means of an axle 39, and the arms 35 supporting this drive roll are swung about the axes of the power roll as a center by means of a spring 40 to yieldingly maintain the drive This guide .causes the beam to be lifted substantially provided 33 as a center and at the roll in engagement with the edge of the beam head 16 during its driving action.

The swinging arms 35 mounting these drive rolls are limited in the movement caused by the spring 40 so that when the beam is removed from position the drive rolls will be maintained in substantially the position illustrated in Fig. 3, and in which position the beam will engage these rolls as it is moved upwardly as above described and swung against these rolls to move them slightly and the arms upon which they are mounted by yielding of the springs 40 so that firm engagement of the parts is maintained.

The pulley 34 is driven by a suitable belt 41 from a motor 42 and on this motorthere is provided a specially constructed pulley 43 formed of two inwardly bevelled or inclined disks which are forced together by a spring 44a. The belt 41 is inclined on its edges or generally V shapedon its edge to fit the inclined surface of the disk 43 so that the speed of driving will be varied, dependent upon the amount the belt is forced inwardly toward the center of the pulley 43, and this amount of movement towad the center is dependent to some extent upon the tension of the belt; in other words,if the motor 42 and its pulley 43 will be moved further from the pulley 34, the belt would move inwardly toward the center of the pulley 43 by reason of the expansion permitted between the disks by the spring 44a, and I have utilized this'construction to vary the drive of my beam in order to maintain a linear speed on the warps substantially constant; thus I have 47 which is driven by a worm gear 48 and worm 49, while the worm 49 is driven by a worm wheel 50 and worm 51 on the axle of the power roll 33, so that as the power roll drives the roll 37 which in turn drives the warp beam, the motor will be gradually moved away from the power roll 33, thus drawing the belt 31 inwardly between the disks and decreasing the speed of the power roll and consequently the speed of the driving rolls and the warp beam, so that a substantially constant linearspeed of the warps will be maintained even though a larger diameter of the work is being accumulated about the beam.

I have provided a drive for th beam is driven and which drive is particularly adapted for a mounting of the warp beam so that it may be raised or lowered from position to be rolled to or from the machine and mounted in its bearings prior a mounting block 44 which slid-' ably mounts the base 45 of the motor 42 to its being'mov ed to'its driving position. By this arrangement with the drive out of contact with the yarn, and there should be a slip between'the beam and the drive, then the driving cylinder will not polish the yarn as where the drive is in contact with the yarn and so will not injure the same. Also I find that this arrangement is such that a slack end of the warp will drop away warp beam having heads, and a driving roll having an elastic surface positioned to engage the edge of one of said heads to turn the same for winding of warp threads or the like thereon.
