POWER-TRANSMITTING APPARATUS.

Specicaton of Letters Patent.

Patented Nov. 17, 1914.

Application filed December 20, 1913. Serial No. 807,840.

To all rwhom it may concern Be it known that I, WILLIAM H. RonnrnLn, a citizen of the United States, residing in the city of Richmond, in the county of Vavne, and in the State of Indiana, have invented a new and useful Power-Transmitting Apparatus, of which the following is a full, clear, and comprehensive specification, being such as wili enable a mechanic to make and operate the same with precision.

This present invention relates to a power transmitting mechanism constructed on substantiall-y the same principles as that of my former invention which was set forth in my application iiled June 30th, 1913, Serial No. 776,488., allowed Nov. 17, 1913, but incorporating, in this instance, 'certain features whereby the driven element may be rotated reversely to that of the driving element.

The object herein attained is the provision of a gearless and practically frictionless apparatus fortransmitting power reversely to that of the driving shaft, at the same time providing an apparatus which will be noiseless in operation, practically indestructible in use, and adapted to transmit a smooth and even change of direction regardless of proper manipulation on the part of the operator.

Other special objects and Iadvantages of my present invention will be brought out in the course of the following specification.

It should be remembered that the principles of my invention may be carried out in a variety of ways, but that which I have determined to be the most practical is shown in the accompanying one-sheet of drawings, in which- Figure 1 is a perspective view, partly in section, of the construction incorporating my invention. Fig. 2 is a vertical section, taken centrally through the construction shown in Fig. 1'. And Fig. 3 is a detailed perspective view of the spool and the spindle or driven element, which is integral therewith.

Similar indices denote like parts throughout the several views.

Referring now to the invention in detail: Numeral 1 denotes the base, from which eX- tend upwardly the two separated standards 2 and 3, each carrying on its upper ex'- tremity the respective bearings 4 and 5 which are in horizontal alinement with cach other. Revolubly mounted in the bearings 4 and 5 is the Shaft c, constituting the driting element. Formed integral with, or rigidly secured on, the shaft 6 between the bearings 4 and 5 is the boss i' which is concentric with the shaft G, and whose length is less than the distance between the bearings 4 and 5 for reasons hereinafter made apparent. Secured to the standards 2 and 3 and extending across therebetween and located near the base 1, is the bar 8 on which the lower portion of the clamping-ring is hinged. Said clamping-ring comprises the two segmental members 9 and 10, whose lower ends are interlockcd where they are concentrically pivoted on the bar 8, substantially as shown. Extending up from the upper end-portion of member 9 are the two spaced- apart ears 11 and 12. And in like manner extending up from the upper end portion of member 10 is the ear 13.

Mounted between the ears 11 and 12, on,

the pivot 15, is the angular lever 16 which extends upward and forward as shown. Mounted on the ear 13, by the pivot 17, is the link 18, the upper or forward end of which is pivoted to the upwardly extending end of the lever 16 on the fulcrum 19 carried by said lever. By the above described construction it will be apparent that when the lever 16 is turned in one direction on its fulcrum 19 the upper ends of the members 9 and 10 will be brought toward'each other, While if the said lever is moved in the opposite direction the said members will be moved apart, for the purposes hereinafter made apparent. Revolubly mounted around the boss 7 is the spool which comprises the two end disks 20 and 20', which are integrally connected near their peripherics by the bars 20". Formed in the edges of the disks 20 and 20', cutting the peripheries thereof, are a plurality of notches b, in this instance there being six of said notches `in each disk. Formed through the center of the disk 20' is the aperture a, whose diameter is slightly greater than is the diameter ofl the boss 7 which may pass therethrough as the device is being assembled or taken apart. Extending out from the center of the disk 20 is the hollow members 9 and 10. Extending out in an axial direction from the center ot each end of each of the rollers 21 are the pivots c, which are concentric with their respective rollers. Each of said rollers 21 is mounted both to revolve and to move radially, to -attain which there is slidably mounted in each of the notches Z2 a bearing or guideblock 22, each having a central aperture therethrough for the pivots c of the rollers 21. Each of said guide-blocks isprovided on two of its edges with lips whereby it is prevented from working outward said lips acting as guides for the blocks as they move in and out in their notches Z9. The spindle 23 is journaled in the bearing 5, and the shaft 6 extends therethrough, whereby the bearing 5 provides a support both for the shaft 6 and the spindle 23, as shown in Fig. 1. A plurality of rollers A are located between the boss 7 and therollers 21, the same being parallel thereto and contacting therewith, as indicated in Fig. 2. The

' rollers A are of the same length as the rollers 21 but they have no pivots on their ends, but their ends are adapted to contact With the inner faces of the disks 20 and 20, which prevents them from being displaced laterally. The relative size of the boss 7, the rollers 21, and the rollers A may be 'variously changed to meet various conditions or desiderata, depending upon the speed-at which it is desired the spindle or driven element is to travel with relation to the shaft or the driving element. It is contemplated that a pulley, gear, sprocket, or the like (not shown) maybe secured o n the spindle 23, through which power may be transmitted to a machine or the like.

llt will be observed that the various elements may be assembled as in Figs. 1 and 2. It now the shaft 6 be rotated ,in either direction, with the lever 16 turned upward to its limit of movement, it is evident that the spindle 23 will remain at rest. But it the lever 16 be now moved forward, to the position in which it is shown in Figs. 1 and 2, the upper` ends of the members 9 and 10 of the clamping ring will be brought toward each other, thereby clamping the members 9 and 10 upon the rollers 21, and they in turn upon the rollers A, thereby pressing the, latter into contact with the boss 7. Thereforethe rollers A will revolvelon the periphery of the boss 7 and also upon the rollers 21, thereby causing the rollers 21 to revolve upon the rollers A and upon the inner face of the members of the clampingring.

The operation just'described will eventuate to revolve the spool, and consequently the spindle 23, in a reverse direction to that ofthe shaft 6, thereby accomplishing the primal object of this invention.

It should be understood that this invention may be employed in connection with other devices for operating the driven element at various speeds with relation-to the driving element, such as that shown in my former invention above referred to.

lt desire' that it be understood that various changes may be made inthe several details of construction from that herein set forth, the parts may be differently arranged, and the proportionate sizps of the several parts may be varied therefrom, Without departing from the spirit of this invention and without sacrificing any of the advantages thereof.-

Having now fully 'shown and described my invention, what l claiml and desire to secure by Letters Patent of the United Statesisf 1.An apparatus ofi-the nature set forth comprising a shaft having a boss carried thereby and concentric therewith, a spool concentric with the'boss, a plurality of outer rollers mounted and radially movable in ysaid spool, a plurality of inner rollers loosely located between the bossand the outer rollers, a clamp surrounding the spool, means yfor contracting said clamp upon the outer set of rollers whereby the spool will be rotated reversely tothe shaft. 2.
