CLOTH-WINDING MACHINE.

Specification of Letters Patent.

Patented May 18, 1920.

Application filed April 26, 1918. Serial No. 230,855.

To all whom it may concern:

Be it known that I, CHESTER E. MONEY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Cloth-Winding Machines, of which the following is a specification.

My invention relates to machines for winding fabrics of various kinds, which I shall refer to generically as cloth, upon a reel, which usually assumes the form of a board. The cloth may be wound singly or doubly. The invention is concerned more particularly with the means for supporting and rotating the board, and one of the objects of the invention is to provide means whereby the board may be readily placed in or removed from the machine. Another object is to provide means whereby boards of various lengths and sizes may be accommodated.

I obtain my objects by the mechanism illustrated in the accompanying drawings in which- Figure 1 is an elevation of the board and its supporting and operating devices.

Fig. 2 is a front elevation of the parts shown in Fig. 1.

Fig. 3 is a detail showing one of the grippers for holding the board on the head shaft.

Fig. 4 is a face view of the gripper shown in Fig. 3.

Similar numerals refer to similar parts throughout the several views.

In the form selected to illustrate the invention, the machine has a main frame 1 having bearings 2, 3 at the top for the head shaft. In the illustrated form this shaft consists of two sections 5 and 6. The sec tion 5 is journaled in the bearing 2 and the section 6 is connected to it by means of a universal joint 7 This taken in connection with the fact that bearing 3 is open at the top permits the section 6 of the shaft to be lifted out of said bearing when the cloth is being removed. The shaft is driven by any suitable means such as the sheave 10 driven by the belt 11 from any suitable source of power (not shown).

The cloth board 15 on which the cloth is to be wound is mounted in two holders which are preferably alike, except that one is fixed to the shaft and the other is slidably mounted on it, but may be clamped in any desired position. I will first describe the one that is slidable, the details being shown in Figs.3and 1. Asleeve 17 loosely encircles the shaft and is provided with two ears 18 which carry a fulcrum pin 19 on which is a cam 20 manipulated by a handle.

21. The construction is such that when the handle is raised the cam will release the shaft but when lowered the cam will grip the shaft and securely hold the sleeve in the position to which it has been adjusted. Fastened to the inner end of the sleeve is a plate 25 having an upturned flange 26 at the end. This flange makes an acute angle with the main body of the plate so as to form a V-shaped socket for receiving the end of the cloth board. In addition it has teeth 27 which are here shown in the form of knife blades capable of entering a short distance into the fiber of the wood at the end of the board. This produces a very effective gripping means, for by moving the holder up close and firm against the end of the board and then tightening the cam 20 the board will be held against movement in any direction relatively to the holder or gripper. As above stated, the companion device 30 at the opposite end of the board is similar in construction, except that it is rigidly fastened to the shaft as shown in the upper left corner of Fig. 2.

In operation, the operator first adjusts a cloth board to the machine by gently forcing one end of the board into the jaws of the gripper 30 after which he slides the other gripper 25 into engagement with the opposite end of the board and then clamps the gripper onto the shaft by rotating the handle 21 to acting position shown in the drawings. He then throws on the power, causing the sheave 10 to rotate and drive the shaft and board. It is evident that after the entire piece of cloth has been wound onto the board the shaft 6 will lie between the board and the cloth. The removal is a simple matter, however, for all that is necessary is to lift the free end of the shaft up clear of its bearing 8, loosen the clamp by throwing up the handle 21 and then slipping the clamp and attached gripper off over the free end of the shaft. The board itself, with the cloth on it, may then be slipped off the shaft endwise, after which the slidable gripper may be replaced and the shaft again lowered into its bearing 3 ready for a repetition of the operation.

It will be seen that the machine is both simple and effective, and will operate on cloths of various widths. Furthermore, it takes only a moment to secure a fresh board in place and requires but a moment to remove the board and cloth after the cloth has been wound up. The device does not depend entirely upon the clamp of the sleeve 17 for transmitting rotary movement to the board for the gripper 30 at the left is permanently fastened to the shaft and hence is in no danger of slipping. However, the torque is not obtained from the permanent gripper alone because the clamp has a strong gripping action on the shaft and hence the rotative effect will be applied simultaneously to both ends of the board.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A cloth winding machine having a head shaft adapted to be rotated, supporting means for said shaft at opposite ends thereof and means for holding the cloth board upon said shaft,-said holding means including a gripperadapted to slide off the end of the shaft,said shaft having a joint in it whereby one end may-be lifted out of its joint near the driven end of the shaft-for.

permitting the other endfto'be swung/and bearing forthe free end of the shaft out of which the shaft may be lifted when the cloth-wound board is to be removed, and means on the shaft for holding the board and causing it to rotate with the shaft said holding means including a gripping jaw which may he slipped endwise off the free end of the shaft.

In Witness whereof, I have hereunto subscribed my name.

CHESTER E. MONEY.
