7 GOVERNOR FOR WATER-WHEELS.

- SPEGIFIGATION forming part of Letters Patent No. 295,060, dated March 11, 1884.

Application filed May 22,1883.

To u-ZZ whom it In/toy cancel-12 Be it known that 1, CHARLES J. SHUTTLE WORTH, of Springville, in the county of Erie and State of New York, have invented new and useful Improvements in Governors for W'ater-iVheels, ice, of which the followingis a specification.

This invention relates to an imp rovement in governors for water-wheels and other motors in which the supply of water or other actuating agent is regulated by a. ball-governor, and

' has for its object to so construct the governor that the normal speed of the water-wheel or other motor or engine can be increased or reduced by a simple adjustment of the governor, and without requiring a change in the size of any of the parts, as heretofore.

A further object of my invention is to prevent the great variations in the speed andwater-supply, which occur when these governors are used, and to render the water-supply more regular and the speed more uniform than heretofore.

My invention consists, to these ends, of the improvements in the governor, which are hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, consisting of two sheets, Figure 1 is an elevation of my improved water-wheel governor. Fig. 2 is a top plan view thereof. Fig. 3 is an elevation at right angles to Fig. 1. Fig. at is a sectional elevation of the spindle and connecting parts on an enlarged scale. Fig. 5 is a perspective View of the spring.

Like letters of reference refer to like parts in the several figures.

A represents the stationary frame of the governor.

t represents a horizontal shaft supported in bearin gs b, which are secured to the top pieces of the frame A.

B is a pulley, which is secured to the shaft 1) and rotated by an endless belt from a suitable part of the machinery which is driven by the water-wheel. The shaft Z2 may be driven by gear-wheels, if preferred, or by any other" suitable transmitting mechanism. so that its rotation bears afixed relation to the speed of the driven machinery. r

0' represents the spindle or vertical shaft,

(X0 model.)

provided at its upper end with a bevelwvheel, c, which meshes with a bevel-wheel, c", on the shaft b, so that the spindle is rotated from the shaft 1). The upper end of the spindle is supported in a bearing, d, in such manner that the spindle can move vertically in the same. The bearing (Z is attached to a bridgetree or cross-piece, D, forming part of the stationary frame. The lower end of the spindle is supported in a step, e, which is formed on an adjustable bridge-tree, The latter rests with one end upon a plate, f, secured to one of the bottom sills of the frame A, or it may be pivoted to said plate, if preferred, in such manner that the opposite end of the bridgetree can be raised or lowered at desire. The free end of the bridge-tree E is provided with a vertical set-screw, g, which works in a screwthreaded opening in the bridgetree and rests upon a wear-plate, 5 secured to one of the bottom sills of the frame A. The upper end of the set-screw g is provided with a hand wheel, 9', whereby it is turned. Upon turning the screw gthe bridge-tree E andthespindle c, resting thereon, are raised and lowered. g is a jam-nut applied to the screw above the bridgetree E for locking the latter in p0 sition after it has been adjusted.

h is the horizontal shaft, whereby the position of the gate is controlled. The shaft is supported in bearings h,seciired to the frame A, and provided with a pulley, H, to which an endless belt is applied, whereby the shaft h is connected with the mechanism for opening and closing the gate in such manner that by turning the shafth in one direction the gate will be opened, while by turning said shaft in an opposite direction the gate willbe closed.

I is a gcarwvheel secured to the shaft 71 and i is a pinion which meshes with the wheel I,

and is loosely mounted on a horizontal shaft,

j. The latter turns in bearings j", secured to i is more effective.

spindle rotates with the normal speed.

end of the shaft h, for turning the latter and latter is provided with a key or feather, n;

which projects into a groove in the bore of the sleeve n and causes the latter to move with the spindle, while permitting the sleeve to move vertically on the same. The wheel N is adapted to engage against the upper side of the wheel M, and the wheel N is adapted to engage against the lower side of the wheel M, and both wheels N N are arranged so far apart that one will clear the wheel M when the other runs in contact therewith, and that both wheels can be so adjusted as to clear the wheel M.

Instead of constructing the wheels MNNin the form of bevel-wheels, as shown, the wheels may be made in the form of plain cylindrical disks; but I prefer the constructionshown, as it The wheels may be constructed with teeth, if preferred.

0 represents the governor-balls, and 0 the arms, whereby they are connected with a crosshead, 0 secured to the spindle 0, below the wheel N p are links whereby the arms 0 are c011- nected with the wheel N, the links being pivoted to lugs p on the arms and lugs 12 on the under side of the wheel N, so that the wheels N N are raised when the balls 0 separate, and lowered as the balls approach each other.

T is a curved spring, which connects the wheel N with the spindle 0. The spring a" is secured with its upper end to the wheel N, and with its lower end to a collar, 8, which is adjustably secured to the spindle by asetscrew, or otherwise. By raising or lowering the collar s on the spindle the tension of the spring 1', the position of the wheels N N with reference to the wheel M and the normal position of the balls can be regulated. The motion which is imparted to the shaft 12 by the driven machinery is transmitted to the spindle c by the bevel-wheels 0 0 The spindle is so adjusted by the bridge-tree E that the wheels N N will run clear of the wheel M when the WVhen the motion of the spindle falls below the normal speed, the balls 0 approach each other, the wheel N comes in contact with the upper side of the wheel M, and the motion of the latter is transmitted by the shaft j and pinion i to the wheel I and shaft h in a direction in which the gate controlling the supply of water of water, the balls diverge and raise the wheel N from the wheel M, thereby stopping the mechanism by which the gate isoperated. If the acceleration of speed should continue, the lower wheel, N, will come in contact with the lower side of the wheel M, and turn the latter and the gate mechanism in an opposite direction, whereby the water-supply is correspondingly reduced. The vertical movements of the wheels N N on the spindle c and the movements of the governor-balls cause a de flection of the spring 0" out of its normal position. By adjusting the tension ofthe spring the movement of these wheels and balls can be nicely regulated, so that the proper supply of water-and the normal speed are maintained with greater regularity or much small variations than in ordinary governors, which cause alternately an excessive and deficient watersupply and corresponding irregularities of speed. If it is desired to increase the speed, the spindle c is lowered by the bridge-tree E, so that a greater speed will be attained before the lower wheel, N, comes in contact with the wheel M and reduces the water-supply.-

If a slowermovement is desired, the spindle is correspondingly increased by the bridgetree. These adjustments of the spindle do not affect the adjustment of the spring r, whichmoves'with the spindle. The spring is so adjusted that it will be deflected out of its normal position by the governor-balls when the latter move out of their normal position.

The s rin offers therefore a resistance which retards the governor-balls in moving out of their normal position, and the range of movement of the governor-balls is thereby considerably reduced, and the supply of water or other actuating agent to the machinery more perfectly controlled and rendered more uniform,

My improved governor may, with certain obvious modifications in construction, be employed in connection with steam-engines.

I claim as my invention- 1. The combination, with a ball-governor, of a spring secured with one end to the spindle of the governor, and with its opposite end to a collar or sleeve which is moved by the governor-balls, the spring being adapted to is controlled, of a ball-governor, a spindle to which the governor-balls are attached, and an adjustable step supporting said spindle, whereby said spindle can be raised or lowered to regulate the normal speed of the machine,
