BELT WINDING AND STRETCHING MACHINE.

o Y SPECIFICATION forming part of Letters Patent No.,269,520, dated December 26, 1882.

' Application filed Xovember l, 1881. (No model.)

To all whom it may concern:

Be it known that I, MAURICE GANDY, a subject of the Queen of Great Britain, and a residescription of my invention in such full, clear,

and exact terms as to enable any one skilled in the art to which it appcrtains or is most nearly connected to make and use the same, reference being had to the sheets of drawings annexed to this specification, and to the figures of reference marked thereon.

My invention has for its object the nullifying or killing of the elasticity of machine-belts, especially cotton-canvas belts constructed of cloths stitched together, as patented to me in the United States of America on the 1st day of June, 1880, No. 228,186.

Itis within my knowledge thatbelt-stretching machines of certain constructions are known in the United States of America. For example, I am aware that stretch-machines on the lever principle are in use for stretching thestrips of leather usedin the man nfacture of leather belts;

' and I am also awarethat machines have been are subjected.

In the drawings, Figure .l is a sectional side elevation illustrative of a machine used for winding belts under a slight tension, used solely for the purpose of winding the belt into a compact coil or parcel for sale. This machine is of known construction, and is only here used by me to point out the state of the art prior to my present application for Letters Patent. In the drawings, B is the belt, which is led between the plate and roller a, and the rollers 12 b, theupper 0t whichis carried on the swinging arm b and weighted by the weight b. The belt B then passes between the rollers c c and the spring-retained plates d d and the rollers e c. The belt is then wound on the barrelf, as illustrated, being kept in position during the winding by the roller h, which is adjustable between two swinging arms, 0', the

guides being guged on the roller h to suit the width of the belt being wound. By this machine the belt B is evenly coiled on the roller f, the slight tension of the mechanism insuring a compact coil.

Under my invention I so construct a winding-machine that I can, when winding, so coil belts that any elasticityjthat they may have is, so to speak, nullified or killed by winding the belts on a barrel under stretch from the pressure of heavily-weighted nipper-plates. The belt remaining under this extreme stretch in the coil or parcel is, when opened and used, found to be free from elasticity, the same having been, so to speak, nullified or killed.

The machine by which I accomplish the objects of my invention is illustrated in plan at Fig. 2. Fig. 3 is a sectional elevation through Z Z, Fig. 2. Fig. 4. is an end elevation of Fig. 2. Fig. 5 is a detail in section of the winding-barrel. Fig. 6 is an end view of the swinging bearing. Fig. 7 is an end view on a larger locking-collar K. (See Fig. 6.)

The other bearing of the barrel A is in a swinging bracket, J, provided with the 0 fed to the wiading-barrel A through the gaged under the roller P, which is-provided with the adjustable guides Q Q, the adjustment being performed through the central screw-rod and hand-wheel, R.

The gaged guide, which is an essential feature of the machine, is detailed at Fig. 7, and consists of the gage-pieces L L, which travel on. the bar S, and are adjustable by the right and left hand screwed rod T, worked by the Wheel U.

By winding the belt on the expanding-roller A from the press-plates M M, which are subjected to an extreme nipping-pressure, I am enabled to wind the belts under such extreme tension that the belt is coiled under its maximum stretch, and the storing of the coiled belt under such maximum stretch kills the elasticity of the belt. To remove the belt from the barrel A, alter-it has been wound into the coil, I release the cones E, so that the segments close in and release the coil, which can be then withdrawn from the barrel -A by opening the swinging bracket and bearing J, forming a gate.

Having now described my invention, 1 would have it understood that I disclaim the stretchmachine as shown at Fig. l of this specification; but

What I claim, and desire to secure by Letters Patent, is

1. The method substantially herein described of winding and maintaining the belts under tensimnwhich method consists of winding the belt directly from the tension-nippers or pressplates, under maximum tension, upon an exbelt against the winding of the barrel, substantially as shown and described, for the purposes specified.

3. In a belt winding and stretching machine, theinterchangeablepress or nipperplatesmade of separate pieces of steel or other suitable metal, and combined with the nipper-jaws and levers to hold and force the nippers together, substantially as described.

4. In a belt winding or stretching machine, the press or nipper plates constructed with the lower plate rigid and the upper plate hinged, and provided with pressure-power, substantially as herein described and shown.

5. In a belt windingand stretching machine, the winding-barrel made of segmental pieces, expanded and contracted by cones, substantially as shown and described.

' 6. In a belt winding and stretching machine, the combination of a winding-barrel A, with a fixed and swinging bearing, substantially as described, for the purpose specified.

MAURICE GANDY.
