Patented Nov. 19, 1940 UNiTED STATES PATENT OFFECE 2 Claims.

This invention relates to improvements in winding apparatus in general but it is directed particularly to winding machines known as batchers or batching frames.

In the textile industry, a batcher is employed for winding into a roll a web of fabric as it comes from a tenter machine or from some other apparatus. Such a machine includes a winding arbor on which is a core of four or five inches in diameter and on this core the web is wound into a roll having a diameter of from twenty-four to twenty-eight inches.

The fabric web comes from the tenter machine or other apparatus at some substantially uniform lineal speed and it is desired and necessary to wind up the web at a substantially uniform tension. The arbor of the batcher is, of course, rotated and as the winding operation progresses the diameter of the roll increases.

The arbor is driven by a direct current motor in the circuit of which there is a resistance so that the motor has a rather definite torque or pull. With this arrangement the motor will have a certain pull on the web so as to bring about a more or less uniform tension and the speed thereof decreases as the roll diameter increases.

The motor however will. have a rather definite capacity. That is, it may provide the desired tension and have the ability to operate successfully from between an initial speed of 100 R. P. M. for the arbor when the roll is first started to a speed of R. P. M. when. the roll is completed.

Batchers are employed for Winding operations with the material being delivered thereto at various lineal speeds. That is to say, webs may be delivered for the winding operation at various lineal speeds calling for an arbor speed at the beginning of fifty or several hundred revolutions per minute. In other words, the speeds at which the webs are delivered vary within a very wide range and require a wide range of arbor speeds for the beginning of the winding which results in a similarly wide range of speeds at the completion of the winding operation. The objection is that the capacity of the motor is not sufficient to cover the range. According to this invention means is, provided to facilitate uilization of the capacty of the motor for that part of the range within which it is desired to operate and the same is accomplished by a novel construction and arrangement which is not only simple in form but also efficient in operation.

According to another feature of the invention, means is provided for maintaining the carriage, which has a roll engaging the roll being wound,

in alignment so that the said rolls axis is at all times parallel to the axis of the winding arbor.

Various novel features of the invention will be hereinafter referred to in connection with the accompanying description of the preferred formof the invention, reference being had to the drawings wherein:

Fig. 1 is a plan view of an apparatus embodying the novel features of the invention;

Fig. 2 is a partial side elevaticnal view of the -lfl mechanism for driving the arbor of the machine shown in Fig. 1; and

Fig. 3 is a side elevational view of the machine shown in Fig. 1.

Referring now to the drawings in detail the!!! machine of the invention will be fully described.

End frames 2 and 4 are provided which may be connected together in some suitable manner as by members such as 6 so as to provide a rigid frame work. 20

A bearing ID on the forward end of frame 4 has rotatable therein a shaft l2, the inner end l3 of which is provided with an arbor socket (not shown). A bearing It on the forward end of frame 2 has a slot [6. An arbor I8 is providedl and is formed so that its end, which is not shown, is receivable in the socket of the shaft end [3 while its other end is provided with one or more pin bearings such as l9 so as to facilitate the rotation of the arbor by the shaft I2.

Rails 20 and 22 are associated with end frames 2 and Li and are secured to the frames at their forward ends by brackets 26 and at their rear end by brackets 26. As shown in Fig. 3, the tracks are disposed in an inclined relation.

A carriage 28 is movable on the tracks El! and 22 back and forth or towards and away from the arbor 18. The carriage there has side brackets 36 and 32 in which are fixed a forward shaft 34, a rear shaft 3% and an intermediate shaft 33. There is a rotatable shaft at below shaft 38. Pin bearings such as 42 are rotatable on the shafts 34' and 3E and these roll on the tracks 2!] and 22, they being held against shifting movements by collars 44. 45

A forward roll 46 is rotatable on shaft 34 and it is held against axial movements by collars 48.

A similar roll to is likewise rotatable on the shaft 36 and it is held against axial movements by collars 52. An expander or spreader roll 54 is rotatable on the shaft 33.

In the operation of the apparatus, a web of material W such as a fabric from a tenter machine or the like passes beneath roll 50 and up and over roll 54 and beneath member 48 in the 55 path as indicated in Fig. 3. As the webis wound up on a core which may be carried by the arbor I8, the expander or spreader tends to straighten the web or to pull it outwardly from the center so that the web of material is made flat and is unwrinkled.

As the web is wound up onto the roll by the rotation of the arbor I8 the carriage is disposed so that the roll 46 bears against the roll of material on the arbor. As the diameter of the roll increases the carriage moves rearwardly or away from the arbor. The tracks 20 and 22 being inclined the carriage tends to move. forwardly so the roll 46 bears against the roll of material with the desired pressure. In. Fig. 3, a roll of material is represented by R. against which roll 46 bears. In Fig. 1 the carriage is shown spaced from the arbor in order to illustrate the parts more clearly.

To insure, however, that the roll 46 is maintained in alignment with the arbor, the opposite ends of the carriage are geared to the track. This is accomplished by means of gears 56 on shaft 40 which are in mesh with racks 58 on the under side of the tracks. By this means, the axes of the shafts of the carriage are maintained in alignment with the axes of the arbor in all positions of the carriage.

A latch hook 60 is pivoted at 62 to the bracket 26 associated with the frame 4 (see Fig. 3). The forward hook end 64 of the hook is adapted and arranged to hook over the shaft end 40 when the carriage is in its rearward position so as to hold the carriage against forward movement.

A motor I0 is provided which is carried by the frame work and it has a shaft I2 which carries a pulley I4. A jack shaft I6 which is rotatable in the frame carries a pulley I0 which is connected by a belt 80 to the pulley I4 of the motor..

A pulley 82 which is fixed on shaft I2 receives belt 8 1 while a pulley 98 on shaft I6 receives a belt 90. An arm 92 is pivoted at 94 to a bracket 96 associated with frame 4.

A stud 92 in the end of arm 92 has rotatable thereon a plurality of members I00, I02, and I04. The intermediate member I02 is shiftable axially relatively to the members I00 and I04. Adjacent faces of the members I00, I02 and I04 are inclined towards one another so that the adjacent faces form cone pulleys IOI and I03. The said adjacent faces are provided with interengaging tongues and slots I06 and I08 respectively which are arranged and adapted so as to permit axial movements of the intermediate member I02 relative to members I00 and I04 but retain the three members in driving relation.

In Fig. 2, the central member I02 is positioned so that a cone pulley IilI at the left is provided which is of a larger diameter than a cone pulley 03 at the right thereof. By moving the central member I02, the diameters of the cone pulley-s may be varied. As the arm 92 is swung clockwise, the belts 8A and 90 act on the member I02 so that it is moved outwardly to increase and decrease the diameters of the cone pulleys. When the arm is swung counter-clockwise, the reverse is true. Therefore, by swinging the arm up or down, the elements I00, H12, and I04 are adjusted so that the arbor is driven at various speeds from shaft 16.

A shaft H0 is rotatable in frame 4 and has a hand wheel II2 fixed thereto. A universal joint H4 connects shaft H0 to a screw member IIB which threadedly operates in a nut H8 pivoted at I20 to an extension I22 of arm 92. A plurality of graduations such as shown on a plate I24 may represent feet or yards per minute or the like. As hand wheel H2 is rotated, the arm 92 is swung in. one direction or the other so that the pointed end of member I22 as shown traverses the graduations.

Lines I20 and I22 represent a power line to the motor and there is a rheostat or variable resistance I24 in said line.

In the operation of the apparatus, it is desired to wind up or to batch a web of material which may come from various machines and at different lineal speeds. The said web may come from a certain tenter and will, of course, be delivered therefrom at a certain lineal speed, such as so many yards or feet per minute. It is desired that the said web be wound up on the core carried by the arbor at a uniform tension. Since one tenter machine may deliver the web at one speed, and another tenter machine or the like may deliver the goods at a very much greater or lesser speed, it is to accommodate various speeds and to provide the desired tension that the apparatus of this invention is adapted.

The resistance may be adjusted so that the motor provides the desired pull on the web so as to obtain the desired web tension. The arm 92 is adjusted so that the arbor is rotated at the beginning of the winding operation at such a speed as will take up the web at the speed delivered to the machine and as will give the desired tension.

As the winding proceeds the roll of web being formed increases in diameter so that the speed of the arbor at the beginning of the roll is less than that at the completion thereof. As the roll diameter increases, the torque or pull of the motor being rather constant, the said motor speed decreases so that the lineal speed of the web is uniform throughout the winding operation.

By means of the apparatus, it is possible to wind up a web at a desired tension and at a desired lineal speed, which factors are substantially uinform throughout the winding operation. The ability of the motor to exert a certain pull according to the setting of the resistance throughout a certain somewhat limited range is made use of throughout a very much greater range by means of the novel construction and arrangement of parts.

While I have described the invention in great detail and with respect to the present preferred form thereof, it is not desired to be limited thereto since many changes and modifications may be made therein without departing from the spirit and scope of the invention. What it is desired to claim and secure by Letters Patent of the United States is:
