GAUZE AND CLOTH WI ING MACHINE.

Tocll whomit may concern."

Be it known that fwe, CARL M. Bone, EKNEST'DECKER, and Louis 0. Ln Duo, citizensoff the UnitedStates, residing at Mid: vale, in the county of Salt Lake and State of Utah, have invented anew and'useful 'lmprovement in a Gauze and Cloth \Vinding Machine, of which thefollowing is a specification.

Our invention-relatesto the art of winding rolls of cloth or other materials. that are presented in the open market in rolled shapes. and in this particular case the ma chine of our invention is peculiarly adapted. for rolling gauze bandages such as are used by surgeons and nurses for dressing Wounds or any other case where a rolled bandage is used.

We are aware that several machines for this purpose have been manufactured, but none has proved to be able to do the work with entire satisfaction. The main object to be attained in winding a gauze bandage into a roll is to apply a continuous even tension to the winding material so that this material presents smooth edges and face, but not so tightly wound but what it can be easily sterilized throughout. To make the tension and subsequent distribution of material be-- ing wound so perfect that it is the same both for the first and the last layer of the bandage is the purpose of our invention. Another feature of our invention is the easy, smooth, and even starting of" the bandage cloth on the needle, which we 21C".

complish by using a removable hook shaped tool. I

In our invention the gauze or cloth bandage is wound on a removable needle, and the proper tension secured by means of a horizontal roller, with either smooth or knurled concave surface depending upon the kind of material to be wound, which moves vertically in slotted guides and rests on top of the bandage whilethe bandage is thus allowing the roller b to move freely vertically in the slots d. The upper ends of the slots d widened out into slots d which form a rest for the roller b when not in use. The roller Z) can have its concave surface either smooth finished, rough, or knurled, depending upon the kind of material to be wound into a roll. The crank disc f and the disc g are carried by the standards a a in containers m? and a and form the side guides for the band age j to be wound and also for the roller 7). The loose pin or needle it which can have any cross section desired but which we show trlangular in section as being pref- 'erable, fits into recesses c and 6', in discs f and g and moves as an integral part of these discs. When a bandage of gauze or cloth is about to be wound, the V needle 71, is inserted into the recesses e and 6', as shown in Fig. 1, forming the removable core ot the bandage. The end of.

the loose bandage is then loosely folded over the needle 71., and the starting tool 11 ishooked over the cloth and the needle 72, as shown in Fig.

The crank disc 7. 1s then given a turn or two by means of crank 70 winding the cloth tightly about the needle h. The starting tool 71 is now'removed, and the roller Z) lifted out of the slots cl 7 and lowered into the position as shown in Fig. lwhere it rides freely of its own weight giving the required ten sion to the bandage while the bandage is being wound into a roll upon needle it when the crank 72 isturned. When the bandage roll is completed, the roller 5 is lifted until the spindles c 0" rest in slots cZ, the crank 70. is then given a'slight.

backward motion that loosens the needle 72, which can now bewithdrawn and the completed bandage removed.

The starting tool 71 can bemade of any kind of smooth material with a hook shaped front, open on the under side so as to be easily placed over the needle 71, and the bandage 7'.

Having thus fully described our machine and the operation, thereof, we claim:

1. A mechanism for winding bandages comprising two opposed rotary discs centrally recessed to receive a winding needle, an axially removable winding needle fitting the recesses and connecting the discs, and a vertically movable pressure roll mounted to rest on the material wound on the needle.

2. A mechanism for winding bandages comprising a winding needle. means for supporting and rotating the needle, a removable starter adapted to closely embrace the needle to start the winding of a web of cloth thereon, and a removable pressure roll adapted to be supported by the cloth as it is wound upon the needle after the removal of the starter.

3. A mechanism for winding bandages comprising two opposed rotary discs centrally recessed to receive a winding needle, an axially removable windin needle fitting the recesses and connecting tfie discs, standards in which the discs are mounted, a vertically movable pressure roll having spindles at its ends, and vertical slots in the standards for the spindles transversely recessed to support the roll during the starting of the bandage on the needle.
