BANDAeE-WINDING. MACHINE.,

T0 LZ/Z wiz/0m, it may concern:

Be it known that I, JOHN G. CRAWFORD, a citizen of the United States, residing at La Grange, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Bandage-finding Machines, of which the followinof is a full, clear,

concise, and exact description. e

My invention relates to a bandage-winding machine, and has for its object to provide a power-driven machine which will be easy to regulate and control and which will be capable of winding bandages with uniformity and great rapidity. I

My invention contemplates in general a bandage-winding machine comprising a rotatable spindle, upon which bandages are to be wound, and a mot-or for operating the same, a standard supporting said motor and spindle, and mechanism carried by said standard for controlling and regulating the coperation of said motor and spindle -to regulate and vary the speed of the spindle. I thus provide a single and compact machine by means of which an operator can wind bandages faster and better than has been possible heretofore, leaving both hands free to manipulate the bandage.

My invention also contemplates an improved construction of the spindle-frame and winding-fingers whereby the bandage to be wound may be threaded through the guidingfingers on the outside ofthe frame and moved to the interior of the frame and fastened to the spindle ready to be wound without requiring the end plate of the frame to be removed, as has been necessary in the bandagewinding machines of the art.

I will describe my invention by reference to the accompanying drawings, wherein` Figure 1 is a front elevation of a bandagewinding machine embodying my invention. Fig. 2 is a detail end view of the spindleframe, showing the manner of threading a bandage through the guide-lingers. Fig. 3 is a plan view of the machine, showing the motor dotted in its alternative position to vary the speed of the winding-spindle.

The same letters of reference are used to indicate the same parts wherever shown.

The rotatable winding-spindle a. of the machine is arranged to be driven by a motor b, carried by a supporting-standard c. The

said standard also serves to support the spin- Specification ofLetters Patent.

dle a, which may be provided with a drivingwheel a', mounted inoperative relation to the friction-disk b, carried by the driving-shaft of the motor b. An arm d may be carried by the standard and serve as a support or journal for the driving-wheel of the spindle,the said arm being preferably forked and the driving-wheel journaled between the two members d d thereof in position to engage The end plate e2 is slidably mounted upon the cross-bars e3 to adjust the frame to varying widths of bandages and is adapted to be secured in any of its adjusted positions by a suitable set-screw.

Fingers ff f2 are provided for guiding a bandage to be wound to the winding-spindle, such bandage being passed or slipped between the guide-'lingers and connected with the spindle. Said fingers are supported parallel to the winding-spindle at the edges of the two end plates, being preferably secured to the stationary end plate e. ject beyond the adjustable end plate, which is cut away so as not to engage the middle iingerf, said finger preferably extending a slight distance beyond the ends of the outer fingers, which the end plate e2 alone engages. It will thus be seen that to thread a bandage between the guide-fingers and connect the saine with the winding-spindle it is simply necessary to slip the bandage between the outer fingers and around the middle nger, outside the end plate e2, and then move the bandage-loop along the middle finger into the interior ofthe frame, when it may be fastened to the spindle a. This may be done without in any way disturbing the adjustment of the end plate e2 or removing the same, which was necessary in winding-machines of the prior art.

Mechanism is carried by the supportingstandard c for. controlling and regulating the The ngers pro- IOC cooperation between the friction-disk b vand the driving-wheel a to regulate and vary the speed of the driving-wheel and the windingspindle a driven thereby, or, in other words, to vary the speed of the driving-wheel without altering the speed o f the motor. To this end I preferably mount the motor l) in suoli lmanner that it may be moved to vary the radial engagement of the friction-disk b with'- the driving-wheel and so to increase or decrease the speed of the rotating spindle. In the present instance the motor is mounted to turn on a vertical axis, as shown in dotted lines in Fig. 3, a spring in the base of the motor-frame serving to return the motor to its normal position. A treadle g is supported at the lower portion of the standard c, being preferably pivoted thereto, and is adapted when operated to turn the motor on its axis. The treadle may be connected with the motor by means of a chain h, extending through the hollow body of the standard and connected with one end of a lever i, pivoted to the standard at the base of the motor, the other end of the lever being connected with the controlling-arm i of the motor, which is adapted when operated to close a circuit for the motor. and turn the same on its axis, a chain i2 preferably connecting the controlling-arm and lever i.

In the operation of the machine the adjustable end plate e2 is first set to adjust the frame to the particular width of bandage to be wound and a bandage slipped through the guide-fingers ff f2, as previously described, and the end wrapped around the spindle. By operating the treadle g the motor is started to drive the wheel a, the speed being controlled by the extent of movement of the motor about its axis, as already described. After the bandage is wound on the spindle into a roll the operator grasps the spindle and gives it a turn in a direction reverse to that in which it is rotated by the motor to loosen the connection of the banda e with the spindle, and the spindle may t iereupon be withdrawn and the roll removed. The bandage is hus wound evenly and tightly into a neat ro I claiml. In a bandage-winding machine, the combination with a. rotatable winding-spindle, of a motor for operating said spindle,
