To all whom it may concern: is adapted for oscillatory valves as well as Be it known that I, JOHN J. TONKIN, of slide valves. Transversely through the Oswego, in the county of Oswego, in the State steam-chest is extended a shaft (2, which is of New York, have invented new and useful suitably journaled in the sides of the steam- 5 Improvements in Valve-Motions for Steamchest and is extended through one of said Pumps, '&o., of which the following, taken in sides. connection with the accompanying drawings, In the interior of the steam-chest are two is a full, clear, and exact description. arms I) b, rigidly attached to the shaft 0 and This invention pertains to the class of having their ends entering between and en- 1o steam-pumps designated direct acting gaging lugs 62 d on the valve a.

Said lever and weight 25 its stroke and reverse the motion of the pisand their connection may be of any suitable ton; and the invention also consists in cerform; but, in order to shield the weight and tain peculiarities of the details of the aforeits track from dust and otherinterference with said valve-motion and auxiliary devices emthe movement of the weight, I prefer to form ployed in connection therewith, all as hereinthe lever of the tube and employ for the 0 after fully described, and specifically set weight 0 a roller or ball, as illustrated in the forth in the claims. annexed drawings.
In the annexed drawings, Figure 1 is aside I is a bifurcated lever, which is pivoted to elevation of a steam-pump whose steam-cylthe exterior of the cylinder beneath the lever inder is equipped with my improved valve- L, and at a point in a vertical line drawn 3 5 motion. Fig. 2 is an enlarged longitudinal from the pivot of the lever L. The two section of said steam-cylinder and its steamprongs I I of the bifurcated end of the lever chest.

To the piston-rod O is attached inder, and O the piston-rod, which is conthe laterally-extending arm e, the free end of 5 5 nected directly with the pump in the usual which is provided with an eye e, axially and well-known manner. I parallel with the piston-rod, and in the said D denotes the steam-chest, and a the valve, eye slides the rod f, which is connected to the which in this case is represented in the form long arm of the bifurcated lever I. To the of a reciprocating or so-called slide valve, rod f are rigidly attached two tappets or nuts 50 but need not necessarily be of that characn n at such distances from opposite sides of ter, inasmuch as my improved valve-motion the arm 6 as to cause the latter to come in contact with said tappets alternately near the ends of the strokes of the piston-rod. Said contact causes the rod f to move with the piston sufficiently to swing the lever I, so as to cause one of its prongs I to tilt the gravitating lever L into-a reverse inclination, and this causes the weight or ball 0 to travel from one end to the opposite end of the lever L. The movement of the lever causes the arms I) b to move the valve a so as to carry it out of communication with the steam-port of one end of the cylinder and into commucation with that of ,the opposite end of the cylinder, and the latter portion of this movement is accelerated by the gravitation of the lever L, due to the weight 0 running to the lower end of said lever and imparting to the same a movement independent of the lever I, which movement is afforded by the play between the lever L and ends of the prongs I I of the lever I, as hereinbefore described.
It is obvious that my improved valve-motion is adapted to be used on engines operated either by steam, air, or water; hence by designating the cylinder B a steam-cylinder I do not wish it to be inferred that I limit myself to the use of my valve-motion solely to steam-cylinders.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In combination with the piston rod, steam-chest, and valve in said steam-chest, a governing-lever actuated by a piston-rod, a gravitating lever transmitting motion from the governing-lever to the valve and having a limited lost motion, and a weight adapted to travel on said gravitating lever lengthwise thereof and past its fulcrum, substantially as set forth.
2. In combination with the valve and governing-lever actuated by the piston-rod, an oscillatory tubular lever partaking motion from said. governing-lever and having its range of motion limited to inclinations equi-' distantly upward and downward from a horizontal position, and actuating the valve, and a weight adapted to roll in said tubular lever lengthwise thereof, substantially as set forth.
3. In combination with the steam-chest, valve, and piston-rod, a shaft extending transversely through the steam-chest, an arm or arms secured to said shaft inside of the steamchest and engaging the valve, a gravitating lever rigidly attached at the center of its length to the aforesaid shaft at the exterior of the steam-chest, aweight adapted to travel on said lever toward opposite sides of the fulcrum thereof, a shipper adapted to rock the gravitating lever, and a rod transmitting motion from the piston-rod to the shipper, substantially as specified.
4. In combination with the steam-chest,reciprocating valve, and piston-rod, lugs on the exteriorof the valve,ashaft extending transversely through the steam-chest, arms rigidly attached to said shaft and engaging tlie aforesaid lugs, a gravitating lever rigidly attached at the center of its length. to the aforesaid shaft outside of the steam-chest and disposed with its mean position horizontally, a weight carried on said lever and adapted to travel from end to end thereof, a bifurcated lever having its branches adapted to engage the aforesaid gravitating lever at opposite sides of its fulcrum, with a limited play between its points of engagement, an arm extending laterally from the piston-rod, a longitudinallyniovable rod connected with the bifurcated lever, and tappets on the said rod in positions to come in contact with the arm of the piston-rod near the ends of the stroke of the latter, substantially as described and shown.
In testimony whereof I have hereunto signed my name this 25th day of June, 1889.
