Patented Jan. 13, 1931 UNITED STATES PATENT OFFICE HENRY A. WISE WOOD, OF NEW YORK, N. Y., ASSIGNOR TO WOOD NEWSPAPER MA- CHINEBY CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF VIRGINIA PAPER-ROLL-CONTROLLING DEVICE Application filed August 25, 1927, Serial No. 215,384. Renewed May 27, 1930.

This invention relates to means for controlling the speed of rotation of the roll which supplies the web to the printing press.

The principal object of the invention is to provide means for controlling the above mentioned roll without the use of a belt which is likely to stretch and slip, and to provide means operating on the end of the paper roll and adapted to control the same irrespective of the diameter of the paper roll. The invention can be constructed in such form as to contact with the end of the paper roll all along the end or to move inwardly with the decrease in diameter of the paper roll.

Other objects and advantagesof the inveniton will appear hereinafter.

Reference is-to be had to the accompanying drawings in which Fig. 1 is an end view of a reel for supplying paper to a printing presswith a referred embodiment of this invention app ied as to avoid the speeding up of the same at times or to avoid toomuch drag on it at other times, due to the stretching or slipping of the belt.

Forthe purpose of avoiding the use of this so-called feeding belt, I employ a shaft 10 driven from the press by means of gearing 11 and 12, partly located on a shaft 13, or in' any other convenient way. This shaft is constantly rotated at such a speed that a wheel or roller 14 slidingly keyed thereto by a spline 15 will rotate at the proper speed to communicate its rotation to the web roll at a surface speed equal to the web speed.

The roller 14 is conical in form and the shaft 10 is located so that the conical surface of the roll will be vertical where it comes in contact with the web roll on the end thereof.

that speed no matter how far the roll 14 is held from the center of rotation of the web roll. In other words by driving the shaft 10 at a constant spee properly controlled, the web will be fed from the circumference of the web roll at the same speed irrespective of the diameter of the web roll by. the feeding of the web therefrom. i

I have shown in dotted lines a position of the roll 14 when the web roll is materially reduced in diameter.

On account of variations in the ends of the paper rolls the driving roller 14 is provided with a spring-pressed rod 27 associated with a stationary part 28 of the frame to put the roll 14 under spring pressure and force it against the edge of the paper roll 16 under such pressure.

The web roll is driven at a constant surface speed and means is provided for holding the driving means against its end.

Although-I have illustrated and described only two forms of the invention I am aware of the fact that other modifications can be made therein by any erson skilled in the art without departing rom the scope of the invention as expressed in the claims.

Therefore, I do not wish to be limited in these respects but what I do claim is:

1. In a paper roll controlling device for a printing press, the combination with means for supporting a Web supply roll in a position free to rotate to supply web to the press, of a shaft operated by the press and a roll rotatable with the shaft and engaging the end of the web roll for rotating the web roll while the ,press is in operation.

' 2. In a paper feeding device, the combination with a web roll supported to rotate freely and deliver a web,'of a rotary member mounted adjacent to the end thereof, means for rotating said member, said member engaging the end of said web roll and controlling the speed of the web delivered therefrom.

3. In a web controlling device, the combination with a Web supply roll, of a positively driven shaft located at the end thereof and at an inclination to the plane of said end, and a conical roll mounted to rotate with said shaft and engaging the end of the web roll for rotating the same.

4. In a web controlling device, the combination with a web supply roll, of a shaft located at an inclination to the plane of the end of said roll, and a conical roll mounted to rotate with said shaft and engaging the end of. the web roll for rotating the same, the angle-of the surface of the. cone being such that an elementof the cone in contact with the end of the web roll is parallel with the plane of said end.

5. In a paper feeding device, the combina tion with a web supply roll,.of a shaft adjacent to the end thereof, a roll on said shaft engaging the end of said web roll and rotating it by such surface contact, the last named roll being conical in form and having its conical side adjacent to the endi'of the Web roll parallel with the plane thereof, and a collar on the base of the conical roll projecting over the edge ofthe web roll to hold the conical roll in position at the periphery of the web roll irrespective of its reduction in size by thefeeding 0f the web therefrom.

6. In a paper feeding device, the combination with a web supply roll, of a shaft adjacent to the end thereof, a roll on said shaft engaging the end of said Web roll and rotating it by such surface contact, and a collar on the base of the roll projecting over the edge of the web roll.

7. In a paper roll controlling device, the combination with a web supply roll, of a shaft operated by the press, said shaft being inclined with respect to the plane of the end of the web roll, and a conical roll on saidshaft, engaging the end of the web roll, and movable up and down the shaft.

8. In a paper feeding device, the combination with a web roll, of a shaft mounted adjacent to the end thereof, means for rotating the shaft, a roll on said shaft engaging the end of said web roll for rotating it, and means for adjusting the shafttoward and from the end of the web roll and for holding it in adjusted positions.

9. In a paper roll controlling device, the combination with a web supply roll, of a shaft, a roll rotatable with the shaft and engaging the end of the web roll for rotating it, and yielding means for moving the shaft toward the end of the web roll to keep the roll in yielding contact therewith.

10. In a paper roll controlling device for a printing press, the combination with means for supporting a web supply roll in a position free to rotate to supply web to the press, of means operated by the press and engagin the end of the web roll for rotating the we roll while the press is in operation.

In testimony whereof I have hereunto affixed my signature.

HENRY A. WISE WOOD.
