Specification of Letters Patent. Patented Apr. 15,1918.

Application filed April 21, 1917. Serial No. 163,689.

To all whom it may concern:

Be it known that I, FREDERICK W. FUL- LERTON, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented new and useful Improvements in Switches for Newspaper-Conveyers, of which the following is a specification.

Myv invention relates to an improved switch for use on newspaper conveyers, and is particularly, though not 1 exclusively, adapted for use on conveyers of the type shown in United States Letters Patent No. 1,138,609, issued to me on the 4th day of May, 1915.

The object of my invention is to provide a simple and eificient switch adapted to facilitate a change of direction in the movement of the papers when it is desired to transfer them from a vertical to a horizontal plane, or vice versa.

In the drawings, Figure 1 is a plan of my improved switch; Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 is a detail of the transfer sheaves and their mountings partly in central section; Fig. 4: is a perspective view of one of the eccentric bushings of the transfer sheaves; Fig. 5 is a detail showing the means for shifting the position of the guide fingers; and Fig. 6 is a sectional detail on the line 6-6 of Fig. 5. I

My switch is applicable to any system of newspaper conveyers consisting of a plurality of pulleys upon which belts are arranged to receive newspapers from a printing press and transfer them automatically in continuous succession or slightly overlapped through any convenient course within the available quarters of the printing establishment to a delivery table where the newspapers are ordinarily stacked and counted. Such delivery table may be located above or below or on the same floor, at a considerable distance from the printing press. In such conveyers the papers when moving in a horizontal plane ordinarily rest upon a single conveyer, but when the line of travel is up or down the papers are carried by friction between two closely adjacent and substantially parallel runs of belts.

In the drawings, the numerals 9 and 10 indicate conveyer pulleys and 11 and 11 carrier belts constructed, arranged, and operated in the usual way. To switch or from a vertical line of such carriers to a horizontal line, or the reverse, I provide the following mechanism: Adjacent to the turning point is a horizontal shaft 12 journaled at each end in a suitable frame 13. The purpose of this shaft is to form' a support for a plurality of transfer sheaves 14 and 15 arranged in pairs and revoluble upon bushings 16 which are eccentrically mounted upon the shaft 12. By reason of such mounting, the sheaves of each pair are ofi'set with respect to each other. The transfer sheaves 14: and 15 of each pair are held side by side by collars or flanges 17 formed on the bushings which are fixed to the shaft 12 by means of set screws 18. The transfer sheaves 14 are driven in a clockwise direction by means of the switch belts 19, which extend from said sheaves to the driven pulley 9, and the sheaves 15 are driven in "a counter-clockwise direction by the switch belts 19 from the pulley 10. These switch belts, which also cooperate with parallel belts 11 and 11 to convey the papers, are disposed in diverging lines of .travel and are brought into such parallel alinement with their respective companion belts 11 and 11 a by the oppositely arranged offsets of the sheaves 1 1 and 15.

To cooperate with the transfer sheaves and their belts, I fix upon the shaft 12, adjacent to each pair of pulleys, a guide finger 20 which may be turned with said shaft into the path of an advancing series of papers, in order to deflect such papers from their former course. This finger in Fig. 2 is illustrated as in position to deflect advancing papers from Y in theirv vertical line of travel. The fingers 20 are shifted into or out of the course of the papers by means of a handle 21 on the end of the shaft 12, and are held in the desired position by means of a stop pin 22 fixed to the knob 23. The pin 22extends freely through an orifice 24in the handle 21. A coiled spring 25 placed in the orifice 24 about the pin 22 presses against a fixed washer 26 on the pin 22 and tends to hold the end of the pin in a perforation 27 on the side of theframe 13, from which position it may be withdrawn by a pull on the knob 23, and when the fingers 20 are shifted by the handle 21, the point of the pin enters a second perforation 27 to hold the fingers in their new position. It will be observed that in shifting the fingers 20, the angular movement of the shaft 12 is so slight that the ofiset peripheries of the sheaves 1d and 15 are not removed from operative position, norvare the lines of travel of the belts 19 and 19 which run over these stantially changed.

In operation, when it is desired to change the direction of travel of the newspapers, the operator simply manipulates theknob 23 to move the pin 22 from one perforation to the other, and thus shifts the position of the guide fingers 20 into the path of the papers which are thereby deflected from thepath of the belts carried upon one series of offset sheaves to that carried by the other series of offset sheaves, when the diverging switch belts cooperating with the com panion parallel belts of the system will grip the papers and transfer them into their new path.

7 Having described my invention, What I claim as new and desire to protect by Letters Patent is:

1. The combination with a plurality of diverging carrier sections adapted to receive papers from .a common source of supply, each section comprising two series of coopera'ting conveyer belts lying parallel to each other, of a switch comprising a shaft mounted adjacent to the line at which said carrier sections diverge, a series of eccentric bushings mounted in pairs upon said shaft, sheaves revoluble upon each of said bushings, so that'the sheaves of each pair are offset with respect to each other, one series of conveyer belts of each carrier section passing. over said sheaves anda serie of guide fingers mounted upon an adjustable shaft and adapted to divert the papers into either carrier section from said common source of supply.
