To aZZ whom it may concern! Be it known that I, JOHN MILES DUVAL ISLAND, a citizen of the United States, residing at Baker City, in the county of Baker and State of Oregon, have invented a new and useful Speed-Regulator forPumps, ofwhich the following is a specification.

This invention relates to water-wheels in general, and more particularly to that class known as bucket-wheels, and it has for its object to provide such a construction and arrangement that the parts will have a smooth and steady working and will be well adapted for the operation of a force-pump.

In the drawings forming a portion of this specification, and in which similar numerals of reference designate corresponding parts in the several views, Figure 1 is a perspective 7 View of the complete structure. Fig.2 is a plan View of Fig. 1, showing the inside of a hopper. Fig. 3 is a transverse vertical section in the line of the axis of the water-wheel,

said wheel and connected parts being shown in elevation. Fig. 4: is a vertical section taken centrally of the hopper shown in Fig. 3 and looking to the left." Fig. 5 is a detail perspective showing the connection of the hinged buckets with the drum of the water-wheel.

Referring now to the drawings, represents a base or platform upon which is built a casing 11, which is rectangular in cross-section and converges downwardly at one side.

This casing is divided into an upper compartment or hopper 12 and a lower compartment 13 by means of a horizontal partition 14, the

compartment 13 being again divided by a vertical partition 15 to form a wheel-pit 16. Passed transversely through the sides of the pit 16 and the opposite side of the casing and journaled therein is a wheel-shaft 17, having a belt-pulley 18 upon one end and a crank 19 upon the other end. Upon this shaft and within the pit 16 is a water-wheel comprising a drum 19 and a hub 20, having connectingspokes 21, and upon which drum is hinged a series of buckets, each consisting of a plate 22, having a hinge connection 23 at its inner edge to the outer surface of the drum and which plate is of the same width as the drum and of a sufficient length to move close to the front wall 24 of the pit when extended. These plates 22 are adapted to extend radially from the drum, on the descending side of the latter, and to lie against the surface of the drum on the ascending side, and to secure this result flexible connections, such as chains 26, are attached to thefront corners of the plates and are extended rearwardly of the direction of motion-of the drum and secured to the pe-' riphery of the latter at the base of the succeeding plates. The lengths of these chains are such as to hold the plates in their radial positions. Thus when the plates begin to ascend and after they have passed from the influence of the stream of water, as hereinafter described,'the chains will collapse and permit the plates to fold against the drum, and thus have what is known as a feathering effect or action.

, In the partition 14 and over the'downgoing side of the water-wheel is formed an outletopening 30,.havin g a slidable closure 3l,a dapted for operation by a lever 32, pivotally mounted in cars 33 upon the inner face of the front of the hopper and by means of which the slidable closure may be reciprocated. Thus if the closure 31 be moved to open the slot 30 and the apparatus be set to receive a stream of water in the hopper the water will pass downwardly and onto the plates ,22 as they successively assume the horizontal position shown in Fig. at and will act to rotate the wheel, the water passing downwardly and under the Wheel and out through the tail-race opening 34 at the back of the casing. At this time the lowermost plates are held in their distended positions, so that'the wheel is not only influenced by the impact againstthe horizontally-disposed plates, but also by the pressure under the wheel.

In order to adapt the construction for an undershot stream, an inlet-opening 35 is formed in the front of the casing and at the bottom thereof and has a slidable closure or gate 36, which is closed during the operation just described. When, however, the undershot stream is to be used, the gate 36 is raised, and a stream may be led through the opening 35 and into engagement with the plates or buckets. Outwardly extending wings 37 are fixed at their adjacent edges to the opposite sides of the opening 35 to direct the water therethrough.

Upon the base 5 is fixed an upright 40, hav

ing a bearing 41 fixed, to its upper end, and

in which is journaled one end of a double crank 42, having its opposite end journaled ing connection with the second crank of the double crank 42, as shown, and thus as the double crank is rotated the pump will be operated.

' In order to form'a cushion 'to absorb the jarincident tothe pumping operation, a flexible steel strap is pivotally connected at one end to the crank 19 and is then curved to place it under tension and is passed through a slot in'an upright 51 upon the base 5, and in which slot it is adapted to move with friction. With this arrangement of spring a steady movement of the mechanism will cause an even sliding of the spring through its slot, but any sudden and uneven movement of the mechanism will act to increase the friction of the spring in the slot, causing it tobend, when the spring, instead of sliding, will bend, and thus act to retard the quickened motion and prevent the sudden jar.

It will of course be understood that the specific shape of the casing and the arrangement of the parts'of the apparatus may be changed, that materials may be varied, and that the apparatus may be built to conform to various conditions without departing from the spirit of the invention.

What is claimed isthe shaft thereof provided with a crank, of'a double crank connected with the shaft-crank for operation thereby, a pump having a piston connected with the double crank, an'upright, and a spring-plate connected with the shaft-crank and having slidable connection with the upright said plate being adaptedto slide when reciprocated at a' normal speed and to bend under the influence of sudden increased motion.

2. The combination with a power-wheel and the shaft thereof having a crank, of a double crank having connection with the shaft-crank for operation by the latter, a pump havinga piston "connected with the double crank, an upright having a slot arranged at an angle to the plane of rotation of the shaft-crank, and a spring-plate pivotally connected with the shaft-crank and slidably mounted in the slot of the uprightsaid plate being adapted to slide when reciprocated at a normal speed and to bend under the influence of sudden increased motion.

3. The combination with a power-wheel having a shaft provided with a crank, of means for conveying motion from the crank, an upright having a slot lying at right angles to the plane of movement of the crank, and a spring-plate pivotally connected with the crank and bent under tension and slidably disposed in the slot of the upright, whereby, as the crank is rotated with a constant motion the plate will slide through the slot when reciprocated at a normal speed and will bend under the influence of sudden increased motion.

Witnesses: 1. The combination with a water-wheel and H. E. COURTNEY, AUGUST PoULNoIs.
