1 VALVE-REGULATING DEVICE FOR WATER-MOTORS.

SPECIFICATION forming part of Letters Patent No. 660,317, dated October 23. 1900.

Application filed. February 1,1900. Serial No. 3,625. \No model To all whom it may concern: ber. Fig. 3 is a plan view of the cam which Be it known that I, DAVID P. SIMS, acitizen operates the slide-valves. Fig. 4: is a detail of theUnited States, residingatLincoln,in the 'view of the foot-tread whereby through the county of Lancaster and State of Nebraska, medium of suitable connections the valves 5 have invented certain new and useful 1111- are operated; and Fig. 5 is a detail view of provements in Valve-Regulating Devices for one of the buckets on the circumference of Water-Motors; and I do declare the following the motor-wheel. to be a full, clear, and exact description of the Reference now being had to the details of invention, such as will enable others skilled the drawings by letter, Y designates the casl in the art to which it appertains to make and ing of the motor wheel P, which wheel is use the same,referencebeinghad to theaccommounted on an operating-shaft and has a sepanying drawings, and to the letters of referries of S-shaped buckets about its circ u mence marked thereon, which form a part of ference, and an outlet passage-way q leads this specification. from said casing. Mounted on said casingis l This invention relates to new and useful the chamber 0, in the walls of which diametimprovements in valve-regulatingmechanism rically opposite to each other are the ports M in connection with rotary impact Water-moand N, from which ports lead the pipes N, tors, and in carrying out the present invenwhich communicate with the interior of the Iiou it is my purpose to generally improve casing P through apertu res Yin the opposite upon the form of construction of water-motor edges of said casing. The ends of the pipes upon which I have been granted Letters Pat- N where they enter the casing are tapered, ent, Serial No. 696,830. as shown. A thimble O is inserted in each More specifically the present invention report M and N, and combined rubber gaskets sides in a valve-regulating mechanism comand valve-seats 0 have their opposite ends prising a chamber into which a water-supply seated, respectively, in the thimbles and pipes (pipe leads and from which ports lead away N. Suitable unions 0 secure the pipes to ion diametrically-opposite sides of the chamthe threaded walls of the ports M and N. (her, in which ports alternately operated Secured to the inner wall of the chamber valves work, said valves being actuated by O is a bracket A, having a central aperture 3 means of a cam rotating with a shaft, which A, in which aperture one end of the shaft B latter is adapted to be rocked in opposite dihas a bearing. The lower end of said bracket rections by means of a foot tread or other is provided with a shelf A ,on which the edges means, whereby the water may be directed of the fiat ends of the valves D and D rest from opposite directions against the circumand slide. These valves have heads 0, 3; ference of the motor-wheel accordingly as it adapted to seat against the inner ends of the may be desired to drive the wheel inppe dithimbles 0 The fiat ends of the valves have ectiop or the ot er. irregular-shaped apertures therein, as illus- T5 these ends and to such others as the intrated, said apertures being oppositely arvention may pertain the same consists, furranged with reference to each other. Keyed 4o ther, in the novel construction, combination, to 01' forming a part of said shaft B is a cam and adaptation of parts, as will be hereinafter B, which cam when the shaft is adjusted in more fully described, and then specifically place rests in said apertures, and accordingly defined in the appended claims. as the shaft is rocked in one direction or the My invention is clearly illustrated in the other one or the other of said valves will be 5 accompanying drawings, which, with the letreciprocated su fficiently to alternately open ters of reference marked thereon, form a part and close the valves. One face of said chamber of this application, and in whichhas a removable cap E, having threaded con- Figure l is a central vertical sectional view nections with the inte 1' of the chamber, through the valves and. regulating mechanand between said cap and the edge of the ism and the motor- Wheel upon which the chamber isdisposedagasket orsuitable packvalve-chamber is secured. Fig. 2 is a crossing. In said cap one end of the shaft 13 has sectional view through the valves and chama bearing, and on the outer end of the shaft foot-tread J,.the forward end of which has a lugl, which lug is slotted transversely.

Mounted on the face of said grooved wheel K is a pin K the free end of which passes through'the aperture l, wherebyas the foottread is rocked on its pivot said wheel K is caused to rock in opposite. directions. As the wheel K rocks backward and forward the disks G, which are connected by belt or band to said wheel, will be caused to rock, and also the shaft B, carrying the cam, which cam rocking from side to side will cause the two valves to alternately open or close, as may be desired, to direct the stream of water to one side or the other of the n1otor-wheel to cause a forward or reverse movement to the motor-wheel.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is-- l. .A valve-regulating device for rotary impact water-motors, comprising in comhi ation with the casing the supply and exit pipes communicating therewith, looselymounted slide-valves controlling the entrance to said exit-pipes, a rock-shaft having a cam loosely held in enlarged apertures in the stems of said valves, and a shelf on which the inner flattened ends of said valve-stems rest and slide, as set forth.

2. A valve regulating device for rotary impact Water-motors, comprising in combination with the casing of the valve-chamber, feeding and exit pipes communicating therewith, the valves for regulating the flow of water through said exit-pipes, a bracket on which the inner flattened ends of the stems of said valves rest and slide, a rock-shaft and cam thereon, which latter turns loosely in cam-shaped apertures in said flattened ends, v

a pulley-Wheel mounted on said rock-shaft,

a tread and connections between the latter and said pulley, whereby said shaft may be rocked, as set forth.

3. A valve-regulating device for rotary impact water-motors, comprising, in combination with the water-chamber with a removable screw-threaded face, pipes leading from the chamber, an angled bracket secured to the inner wall of the chamber, the valves seating against the ends of said pipes, and slidin g on said bracket, the shaft having a bearingat one end, in the bracket, its other end in the screw-threaded face, the cam turning with the shaft, and working in irregularou'tlined apertures in the valve-stems,and means for rocking the shaft whereby; as-the shaft is' rocked, the valves will be alternately closed and opened.

In testimony whereof I aflix my signature in presence of two witnesses.
