FRANK D. MALTBY, OF NEV YORK, N. Y.
OSClnLLA'TING STEAM PUIViPING-ENGHNE.
SPECIFICATION forming part of Letters Patent No. 293,585, dated February 12, 1884.
i Application filed May l9,1883. (No model.) V
To CLZZ whom, may concern.-
Beit known that I, FRANK I). MALTBY, of the city, county, and State of New York, have invented certain Improvementsin Oscillating Steam Pumping-Engines, of which the following is a specification.
My invention is an engine constructed, as fully described hereinafter, to secure a recip-` rocating rocking motion, and to reduce the difculty of securing tight joints and avoid the complexity of ordinary constructions.
The invention further consists in a peculiar combination of engine and pumping appara- In the drawings, Figure l is a sectional elevation, showing my improved engine combined with a pump. Fig. 2 is atransverse sectional elevation.
The case Aof the engine also constitutes the cylinder, and consists of the cylindrical body c and annular heads b b', one of which being flanged and recessed to form chambers receiving the packing and the followers d. Through the heads extends a cylindrical hollow trunk, B, provided with a radial piston, f, which vibrates between two ribs or abutments,
recessed to receive packings e, which prevent the passage of steam between the outer face of the trunk and the edges of the abutments. The piston is likewise recessed to receive a packing, e', making a tight joint between the piston and the inner surface of the cylinder. The piston and abutments are preferably secured detachably and adjustably to the trunk and case, to facilitate construction and repairs. In the abutments and in the piston are channels t, .which admit steam from the chambers m x, on opposite sides of the piston, to the back faces of the packings, thereby forcing the latter rmly against the bearing-surfaces, and making steam-tight joints. In the cylinder are ports m n, communicating with channels m n', leading to a face-plate, on which slides aslide-valve, D, a central exhaust-port, p, leading to an exhaust-pipe, o. The valve D is contained within avalve-chest, E,'to which steam is admitted, and in the chest are chambers x x', receiving the opposite ends of a plunger, J, which is connected to the valve D. Channels p q in the chest lead from the chambers x x to the Vseat of a plug-valve, G, having two ports, r s, the latter always in communication with a central port, t, in the chest. A channel, u, round the upper part of the valve leads to an exhaust-pipe, u.
Vhen the partsV are in the position shown in Fig. l, steam passing through the channel n and port a, into the chamber x', acting on the piston f, turns the trunk in the direction of its arrow until the position of the valve D is reversed, when the steam will pass to the channel m, port m, and chamber x, and from the chamber x to the exhaust through the port a and channel n. The valve D is thrown suddenly and then left in place .by the action of the plunger J,whichvis moved by steam-pressure. shown in Fig. 1, steam passes from the valvechest through the port t and s, into the channel q and chamber x', and throws the plunger and valve .to the left. When the plug-valve G is turned to bring the port rto communicate with the channel q, steam is admitted vfrom the port t, through the port s, to the channel p and chamber zr, and the plunger is thrown to the right, carrying the valve D with it. The exhaust-steam from the chamber into which thev plunger is forced escapes through the port r and channel u to the escape u.
Motion may be communicated to the valve G in any suitable manner. o, upon the trunk B, strikes an arm, o', on the spindle H, of the valve G, as the piston f approaches the limit of its motion 'in either direction, the valve G being thus shifted positively and requiring but a slight movement, while the steam thus brought toact upon the plunger J shifts the valve D instantly and to any desired extent.
I do not limit myself to the use of the means described for moving the valve D, nor to the constructionof the latter, nor to the use of a vplug-valve, G, as a slide orl other valve may be used at this point.
By the construction set forth the vibrationof the main pistonis eected under the positive action of the steam, and with little friction, the bearing-surfaces are of such form as will preserve their shapes for a long time under wear, and the packings are so arranged as to reduce wear and leakage to a minimum.
The abutments g g and piston f are secured Thus when the parts are in the position i As shown, a lug,
detachably by means of bolts or otherwise, so that they can be readily removed and replaced and nicely adjusted.
The engine thus constructed affords special facilities for operatin g pump shaving Vibrating casings or pistons--for instance, such as the pump patented to Brust and Douglas, March 29, 1881, or any of a similar or analogous character-the p ump being arranged, as shown ,Within the trunk B, with an intervening air-space, w, so'as to prevent the cool pump-cylinder from condensing the steam of the engine. The cylinder or piston of the pump is connected to the trunk in any suitable manner to oscillate therewith.
I do not here claim the slide-Valve and operating means, as the same will constitute the subject-matter of a separate application for Letters Patent.
I claiml. The combination of the cylindrical casing having annular heads and longitudinal abutments, a trunk projecting through the heads and carrying a radial piston, and ports and channels and valves, and devices for operating the same from the engine to' admit and exhaust the steam from opposite sides of the piston, substantially as set forth.
2. The combination of the casing, trunk, and recessed piston, and abutments fixed to the casing and truuk, and extending gradually therefrom, with packings fitting said recesses, substantially as specified.
3. rlhe combination of the casing, oscillating trunk, open at the ends, and independent pump arranged Within the. trunk, and connections whereby the pump is detaehably secured to the trunk, substantially as specified.
4. The combination of the casing, trunk, pump, and space w, communicating with the air, as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
FRANK D. MALTBY.
