UNirn STATES HEXRY J. OLIVER, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR OF ONE- HALF TO JOSEPH PRACY, OF SAME PLACE.
PUMP.
SPECIFICATION forming part of Letters Patent No. 350,763, dated October 12,1886.
Application tiled April 7, 1886. Serial No. 108,153.
To aZZ whom it may concern:
Be it known that I, HENRY J. OLIVER, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Steam Pumps, &c., of which the following is a specification.
This invention relates to improvements in valve-machines for steam-pumps of the kind ordinarily used for feeding steam-boilers and lifting and forcing water for general purposes; and it consists, essentially, in the form and arrangement of the valve of the steam-cylinder of said pump, as well as the combination of parts constituting the mechanism for operating the said valve, the objectof this invention being to simplify the construction of the parts, as well as to render more effective their operation, and thus increase the capacity of the pump.
In the accompanying drawings, which form a part of this specification, Figure 1 isa side view of the pump entire, the steam-cylinder portion being shown partlyin section to illustrate the form and arrangement of the valve and steam-chest. Fig. 2 is a side view of the operating mechanism of the valve of the steamcylinder on a larger scale than in the previous figure, these parts especially constituting a portion of my invention.
In both figures the same letters of reference are used to indicate the same parts.
A is the pumping cylinder, with the details of which the presentinvention is not coneerned.
B is the steam-cylinder, and C is the connecting-frame between.
D is the steam-chest of the cylinder B. It is bored out perfectly cylindrical, and is fitted with the piston-valve E.
F is the entrance-pipe for the steam, and the dotted circle at G shows the exhaust-pipe.
The ports leading in from the steam-chest to the working-cylinder are shown at each end. The valve fits the steam-chest only at its ends for a distance a little in excess of the width of the ports, the space between being of lesser diameter to give a free exhaust passage-way. To this valve rod H is in any suitable way firmly secured, the rod, passing out through the N0 model.)
usual stuffing-box, I, extends beyond to rest in and be guided in a bearing, J, provided on the pump cylinder-head.
K is a standing frame rigidly secured to the frame 0, and the two side bars, k k, which also assist in supporting and guiding the valve-rod, holes being bored in the side bars, through which the rod passes. Between the side bars the rod assumes a yoke shapethat is to say, the rod is flattened out and has a vertical slot cut through as wide as the thickness of the vertical levers L and M. The lever L is pendent from the pin Z in the top horizontal bar of the frame K, and the lever M is pivoted to the pin on on the lower bar. Both levers engage with each other, forming a knuckle-joint be tween, as in Fig. 2. They are also connected by the spiral spring N, which hooks on the pins Z m". There may be two ofthese springs, one on each side of the levers, if preferred. One at least of the levers should have a slotted hole where it hangs on its pin, to give the necessary play as they are vibrated. In the drawings this slotted hole is shown in the upper lever.
On the pistonrod O of the pump and steamengine there are two adjustable collars, P P, which are secured in any position they may be set in by set-screws, as is usual. As the piston-rod moves back and forth, these collars strike the lower part of the lever M and move it forward or backward, as the case may be, until both levers L and M assume a vertical position-this without moving the valve-rod H. The slightest movement farther throws the levers out of the perpendicular, and then the spring N suddenly acts to throw them still farther out to the full limit of their motion, at the same time throwing the valve rod and valve attached to the effect of reversing the motion of both engine and pump. The slotin the yoke part of the valve-rod must be made sufficiently long to permit the movement of the levers up to their perpendicular position without disturbing the rod. The levers should be arranged to act upon the rod only at the time the spiral spring enforces a sudden motion at the lower end of the lever M. A frictionroller, Q, may be supplied, against which the collars will strike at the end of each stroke.
In first adjusting the mechanism to throw moving gear herein described, consisting, esthe valve at the proper time the collars should sentially, of the standing frame K, vertical be placed in such a position as to throw the levers L and M, supported thereon, spring N, r 5 valve just before the end of the stroke is slotted valve-rod H, and piston-rod O, with 5 reached; otherwise the valve would not be collars P P, arranged and operating substanthrown at all; but if it should be thrown too tially as set forth. easilytheexperience of the operatorwill guide-l In testimony that I claim the foregoing I him as to this matter. l have hereunto set my hand and seal.
Having thus described my invention, what HENRYJ. OLIVER. [L. s.] 10 I claim, and desire to secure by Letters Pat- \Vitnesses: V
