L etters Patent No. 111,251, dated January 24, 1871.

The Schedule referred to in these Letters Patent audnaking put of the same.

I, JAMES R1GHMOND,`of Iiockport, in the county of Niagara and State of New York,` have invented l certain Improvements in Machinery for Transmitting and Distributing Motive Power, of which thel follow# ing is a specification.-

Nat-ure mul Objects of the Invention.

The first part of my invention consists in the combination, with a main driving-pulley, of the prime mover, and a succession of driving-.pulleys and shafts located at convenient distances apart, and a corre.- spouding succession of wire-rope driving-belts, transmitting the motioncf the prime mover from one to the other of such driving-pulleys and shafts of branch `belts leading from pulleys upon said driving shafts in such direction and to such' points ,as it may be desired to distribute the power of the pri me mover, the object being to furnish motive power to a number of 'individual workshops or manufactories, situated at a considerable distance apart, from a single prime mover. v

rIhe second part of my invention consists in the combination, with the branch-beltpulleys'of adjustable guide-pulleys, arranged as hereinafter specified, to enable the branch beltsto be led ofi" in any desired direction.

'Description of Drawing.

Figure Iis a s ide elevation of my improved ma" chinery.

Figure II isa plan o f same. l

Figure III is a' side elevation on anenlarged scale of one set of transmitting, distributing, and guide- -pulleys, and the frame-work fur-supporting the same.

Figure IV is a plan of same.

-Figure V is a. side elevation of a modified formbcd7frames'1d, resting upon the gallows-fi-anres I?.

G is the :first driving-belt running over pulley C,

and transmitting motion from the prime mover A to the shaft B.

G' is the second driving-belt, running over pulleys C' and O2, and transmitting iu turn the motion of shaft B to shaft B'.l The motion of B may, in the same manner, be transmitted to a-third shaft, and so `on to any desired number.

D D are the branchpulleys,and I, the brauch belts, and

J J l J, Sto., assumed points representing individua Il H', similar guide-pulleys, to direct them as they vlead onto the driving-pulleys, K K', dre., of the in.-

dividual workshops or mannfactories J J1, 85o.

The belts G Gf andI I. are made of wire rope, .and the pulleys over which they lull .hare .grnnved to receive them.

As the pulleys K K', 8t c., may be located botlr above and below the horizontal plane of the distribute ing-shafts B B', and at various angles therefrom, it is necessary that the guide-pulleys H H should be'capable of adjustment tomeet such yarying conditions. Such adjustment is provided for by supporting them' in forked-bracketsL, projecting from acircular frame, M, bolted to the bed-frame, and concentric with the driving-shafts, thebracketsbeing connectedto said frame by bolts and slots, Aso that they may be readily moved to and secured at any desired point thereon.

The axis of 'the guide-wheels should beat right angies to a .plane tangent to the branch driving-pulley,- and parallel'to its axis; and the groove of the pulley should lie in said plane.' To determine the proper aigular position of the guide-pulleys to direct the b lt to any desired point, said tangent plane must be turnedabout the 'axis' ot' the driver until it becomes tangent' tothe driver. The guide-pulley being then moved ou the' frame M until' its groove lies in said plane, the desired position .will be secured, except that allowance should be made for the deflection of the belt hy setting the guide-pulley correspondingly below said plane.

By adjusting theV guide-pulleys as above described, the belts will run trulyin the groove'of the guidepulleys and drivers without any tendency to weer the iianges thereof.

In the modified forin shown in Iiigs. V and VI, the

branch pulleys Dare located' upon a. couutershaft, N, A

driven from the shaft B' by a pair of ruiter-wheels, N N. The circular frames M are concentric with this In tbe'. modified arrangementof theguide-pulleys H H, shown in FigsJVII and 'VIIIftlfiey are made` This arrangement, while allowing the branch belts to be led oli" in any desired direction'7 is open to the objection that the weight of the belt will canse undue wear on the lower flanges of the guide-wheels.

' The distance apart of the distributing-shafts B B', &c., as well as their height above ground, will, in

I practice, vary more or less, according to the requirements of each case.

In distributing power through cit-ies and towns, it

' will, iny many instances, be advisable to run theinain line of belts G G over the tops `of the buildings. In

such cases the-,gallows frames F may be located at the cross streets, and the belts G G made to span ent-ire blocks; or the bed-frames E may have their foundations upon the roofs of the buildings over which the line passes.

In other cases the niain line may follow the course of' a street, the gallows-i'rames being erected at one side thereof, or made to span the saine, as may be' Y most convenient..

l Claims.

1. The combination', with'the main driving-pulley A', of the prime mover A, and series of driving-pulleys C Cl and C'z C, and transmitting-wire-rope beltsG G', of the branch-distributing pulleys D D, guidc-pulleys H H, and branch belts I I, substantially as and for the purpose hereinbefore specified.`

2. '.llhe combination, with the branch pulleysD D, of the guide-pulleys H Hnade adjustable about the axisl of the pulleys D D, substantially as and for the purpose hereiubefore specified.

3. The combination of the adjustable forked guidewheel brackets L with the circular frame M, as and for the purpose hereinbefore speci-tied. l
