WEB-WINDING MACHINE.

SPECIFICATION forming part of Letters Patent Nov 789,070, dated May 2, 1905. Application filed June 23, 1903. Serial No. 162,770.

To all whont it may concern:

7 Be it known that I, EDUARD SOHOENING, a subject of the Emperor of Germany, residing at Berlin, Germany, have invented certain new and useful Improvements in VVeb-I/Vinding Machines for Rolling Up Paper, Woven and other Materials in WVeb Form, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

My invention relates to winding-machines for winding paper, woven materials, and other goods in web form upon a roller, and has for its object to provide a machine of the character indicated which will automatically and tightly wind the web in a straight and uniform manner.

The invention consists of means controlled by the web for regulating the speed of the roller upon which the web is wound.

The invention also consists in the particular construction and arrangement of parts, as h ereinafter described,and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of the specification, and in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a windingmachine having my improvement applied. Fig. 2 is a similar view of the opposite side, and Fig. 3 is a plan view.

In the drawings, a is the winding-roller, mounted in the frame 6, and upon which the web 0 is 'to be wound. The drive-shaft d is mounted in the lower part of the frame and has at one end the pulley a, from which the belt f passes to the pulley g on the shaft of the winding-roller a. On the opposite end of the drive-shaft (Z the driving-pulley it is loosely mounted, and fixedly secured to said shaft and engaging the driving-pulley is the frictiondisk v1, which forms a coupling for connecting the pulley with the shaft, so that the pulley may be rotated by the belt j from a printing or any other suitable machine. The frictional contact of the disk 2' with pulley 7b is adjusted by the screw 7c.

At the rear end of the frame I) is the guideframe Z, which consists of the curved end bars m and tie-rods m. On the lowermost tie-rod m is mounted the roller n, and upon the tierods m are adjustably secured, by means of set-screws n, the guides or, between which the web passes.

In the upper ends of the standards Z1 of the frame 6 is secured the rod 0, and in the lower ends of the said standards is mounted the roller 1). Between the standards Z2 intermediate of the roller p and the rod 0, is centrally and pivotally mounted a frame (1, carrying the roller 1* and rods 3 and t. On one end of the rod 8 is mounted the wormwheel s, which meshes with the worm u on the shaft u, so that by turning said shaft the frame q can be adjusted to increase or decrease the tension of the web. A large wooden roller 41 is mounted in standards on the upper part of the frame 6, and over which the web passes to the roller a after passing over the rod w below the roller o.

WVhen the pulley it, which is connected with the shaft cl by the friction-disk o', is revolved by the belt j, the shaft cZ will be revolved and the rollerc, by means of the beltf, will also be revolved, and the web 0 from a printing or other machine will, after passing between the guides at over and under the several rods and rollers, as shown in the drawings, be wound upon the roller (6.

The machine thus far described is of a wellknown form and about which there is nothing new.

The feed of the web from a printing or other machine to a winding-machine is irregular, as is also the speed with which the winding-roller takes on the paper, owing to the increasing diameter of the roll of paper, and such irregularity causes the web to be unevenly and irregularly wound upon the winding-roller and a tendency to tear the paper, and it is to obviate this objection and cause the web to be wound smoothly and in a uniform manner that I have devised my improvement, which I will now proceed to describe.

To the journal-boxes d of the drive-shaft d are secured the forwardly-projecting brackets A,and between the free ends of the brackets is mounted the shaft B so as to rock. Upon this rock-shaft B are rigidly secured the arms(), and

between the free ends of the arms is mounted the rollerD, which at all times engages the web a c. The rear ends of the arms C are extended rearwardlybeyond the shaft B and are formed into eccentric shoes E, as shown, which are adapted when the roller D and its arms Care elevated by the tightening of the web to engage the brake-wheels F, rigidly secured to the drive-shaft (Z. In order to counterbalance the roller D, an arm G is mounted on the shaft B and extends rearwardly and is provided with an adjustable weight H on its end, as shown in Fig. 3.

In operation as the roller D rests upon the web 0 when the web is slack the brake shoes E on the supporting-arms of the roller are out of contact with the brake-wheels Fon the drive-shaft d, so that the said shaft is driven without hindrance or interference; but should the web become taut, due from its being fed slower or from the winding-roller taking up the web more rapidly, owing to its increase of diameter, the tightening of the web will cause the roller D to be elevated and the brake-[shoes E on the inner ends of the arms of the roller brought into engagement with thebrake-wheels F on the drive-shaft d, checking said shaft and causing a sliding of the friction-disk t on the pulley la, and as the winding-roller a is driven from said driveshaft the speed of the said roller will be correspondingly reduced, thereby causing a slower winding of the web thereon. It will thus be seen that the speed of the windingroller is automatically regulated according to the speed of the web, thereby causing the web to be wound tightly and uniformly upon the rollloer and without any danger of tearing the we WhileI have shown and described the brakeshoes as being formed on the ends of the arms of the roller which engages the web, yet it is obvious that these brake-shoes can be separate from the said arms and independently secured to the rock-shaft. I may also use but one brake-shoe and one brake-wheel, and instead of mounting the roller D in two arms, as shown, it may be mounted in a single arm.

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

1. A web-winding machine having a winding roller or drum, a drive-shaft from which the winding roller or drum is operated, a brake for said shaft, and a swinging member controlled by the web passing to the winding roller or drum and operating the brake, as set forth.

2. A web-winding machine having a winding-roller, a drive-shaft from which the winding-roller is operated, a brake for the said shaft, a swinging member controlled by the Web passing to the winding-roller and operating the brake, and a friction-clutch, one

member of. which is loose on the drive-shaft to allow for the difference in speed of the said member and the shaft whe the brake is applied, as set forth.

3. In a web-winding machine the combination with a winding-roller, a shaft from which the roller is operated, a drive-pulley loose on the shaft, and a friction-coupling connecting the pulley with the shaft, of a roller adapted to engage the web passing to the windingroller, brake-wheels on the said drive-shaft, and brake-shoes moved in and out of engagement with the brake-wheels by the roller, en-

'gaging the web, as set forth.
