MODE. OF OPERATING BELTS AND PULLEYS.

SPECIFICATION forming part of Letters Patent No. 289,441, dated December 4, 1883.

Application filed September 26, 1883. (No model.)

To all whom it may concern:

Be it known that I, RICHARD J. OLIVEY, a citizen of the United States, residing in Buffalo, in the county of Erie and State of New 5 York, have invented certain new and useful Improvements in Mode of Operating Belts and Pulleys, of which the following is a specification.

The object of this invention is to provide the IO means for operating one pair of rollers or two pulleys by means of one belt, when one pulley operates in a line. back of the other, as will be fully and clearly hereinafter shown by reference to the accompanying drawings, in which I 5 Figure l is a side elevation of the pulley, showing the arrangement of the single belt by which the two upper pulleys arranged in different planes are operated. Fig. 2 is a front elevation of the device, and Fig. 3 a top or plan view showing the arrangement of l the pulleys.

a a represent a portion of two rollers of a roller-mill for grinding wheat, &c. a a are the pulleys for driving them, the smaller pul- 2 5 ley, a", being set in a plane back of the pulley a a is a pulley set diagonally, so that the line b, drawn through the center of the face of the pulley,will meet at the periphery of the same the lines I) b, drawn through the center of the 30 faces of the pulleys a. of, as shown in Fig. 3.

b is a pulley set nearly at right angles to the pulley a but the angle may be changed more or less. Its object is to hold that side of the belt to that side of the pulley a", and the object of the diagonal pulley is to guide and carry the 5 belt from the pulleys a? to a c is the driving-pulley, which may be set in any desired position to one side or the other of the pulleys a a. These pulleys are all mounted in bearings made in the usual and 0 well-known way, and consequently a further description here is not necessary. The belt 0 runs in thedirection of the arrows (see Fig. 1) against the pulley 12 which keeps it over to that side of the pulley a From thence it runs 5 over the pulley a and down under and around the diagonal pulley a", which is set so as to carry it to the pulley a3, over which it passes, and from thence,in the direction of the arrow V,down to the pulley a. By this means apair of rollers running at different speeds may be operated perfectly without the use of the usual gearing.

I claim as my invention The pulleys a" of, one being set on one side 55 of the plane of theother, in combination with the diagonal pulleys c 12 and :a driving-belt and driving-pulley, substantially as and for l the purposes described.

RICHARD J OLIVEY.
