PUVIPING-ENGINE.
SPECIFICATION forming part of Letters Patent No. 584,760, dated J une 15, 1897..
Application tiled September 8, 1896. Serial No. 605,128. (No model.)
To all whom t may concern:
Be it known thatI, DAVID A. DECROW, a citizen of the United States, residing at Lockport, in the county of Niagara and State of New York, have invented a new and useful Improvement in Pumping-Engines, of which the following is a specification.
This invention relates to pumping engines, and particularly to horizontal pumping-engines of the compound or Woolf type.
The object of the invention is to improve the construction of pumps of this class and to render the same more efficient in operation.
A further object of the invention is to provide an arrangement and construction where by the size of the pumpe-vlinder will not be limited by the relative location and arrange-f and to the various views and reference-signs appearing thereon, Figure 1 is a view in central longitudinal section of a pumping-en* gine embodying the principles of my invention. Fig. 2 is a plan view of the same, showing my invention applied to two sets of engines arranged side by side and employing a single crankshaft.
The same reference-sign is `employed to designate the same part Wherever it occurs throughout the several views.
Heretofore in pumping-engines of the class to which my invention relates the crankshaft and ily-wheel have been mounted on the pump. In such constructions and in or der to provide a sufficient amount of crank room above the pump-plungers it was necessary to limit the sizeof the pump in order to provide a sufficient vertical distance between the center of the pump-cylinders and the center of the crank-shaft. Again, the connect- .ing-rod from the main shaft has heretofore been attached to the upper end of the workin g engine beam. Such construction necessitated the placing of the driving-motor at an objectionable distance from the pump to be actuated thereby. Examples of engines embodying these constructions are seen in Patents No. 263,694, dated September 5, 1882, and No. 289,828, dated December 11, 1883, to Gaskill, and also in No. 455,868, dated July 14., 1891, to I-Iall, with which patents I am familiar.
In order to avoid the objections noted and to provide a construction wherein the power of the drivingsteam-engine is most effect ively applied to the Work of actuating the pump-plunger and to provide a construction wherein the driving steam-engine may be placed in as close proximity to the pump as possible and a construction wherein the size of the pump will not be limited, I provide the following construction:
Reference -sign 10 designates a suitable frame mounted upon any suitable base and having supported thereby or formed thereon the pillow-blocks 23, in which is journaled Y the main crank shaft 21, upon which is mounted the fly-Wheel 20. Suitably mounted in the frame are the steam-cylinders 1 1l, the one supported by the other. In the particular form shown, which I deem the preferable construction and arrangement, but to which I do not desire to be limited or restricted, the steam-cylinders 1 and 11 are of the compound type, cylinder 11 being the high-pressu re cylinder and 1 the low-pressure cylinder, the high-pressure cylinder 11 eX- hausting into the low-pressure cylinder 1 in the usual or well-known manner.
Reference-sign 2 designates the piston of the low-pressure cylinder 1. 3 designates the pump-cylinder, arranged in alinement with the low-pressure cylinder 1; 4, the pu iup-plunger; 5, the rod, which serves at the same time as the pump-rod and as the piston-rod of piston 2. 6 designates the inlet-chamber of the pump, and? and 8 the pump discharge-chambers. Carried by rod 5 is a cross-head 9, arranged to slide in suitable guides formed in IOO the main frame 10. Upon the rod 13 of piston 12 of the high-pressure cylinder 11 is mounted the cross-head 14, arranged to slide in the guides 15, formed in the frame 10. In suitable bearings in frame 10 is mounted a shaft 17, upon which rocks the working beam 16. rIhis beam is connected at one end through links 1S to cross-head 14 and at its opposite end through links 19 to cross-head i). The crank 21 of the main crank-shaft is connected by a connecting-rod 22 directly toA cross-head 14.
It will be observed from the foregoing description, taken in connection with the accompanying drawings, that the crank-shaft is arranged in the frame between the steamcylinders and the pump, thereby affording sufficient space for the crank 21 without in any manner interfering with or limiting the size of the pump-cylinder, as in the case of the patents above mentioned, and it will also be seen that by connecting the crank 21 directly with cross-head 14 instead of to the working beam, as has heretofore been customary and as shown in the patents referred to, I shorten the distance between the steamcylinders to the pump-cylinders in order to compensate for the change in the location of the crank-shaft and in order to bring` the steam-cylinders in as close proximity to the pump-cylinder as may be possible. It will also be observed that by arranging the lowpressure cylinder and the pump-cylinder in alinement with each other I am enabled to utilize the same piston-rod for both the steamcylinder and pump, and hence the power of the steam-cylinder I is more directly applied to the work of actuating the pump-plunger. It will also be seen that the same frame which supports the steam-engine and pump contains the guides for the cross-heads as well as the bearings for the beam-shaft and the crank-shaft.
Of course it will be observed that an engine embodying the principles of my invention may be employed and operated as a condensing-engine; but as the air-pumps, condensers, and connections may be of the usual or ordinary type and form no part of the present invention illustration thereof has been omitted in the present application.
Many variations and alterations in the details of construction and arrangement, size and proportion of parts would readily suggest themselves to persons skilled in the art and still fall within the spirit and scope of my invention. I do not desire, therefore, to be limited or restricted to the exact details shown and described; but,
I-Iaving now set forth the object and nature of my invention and a form of apparatus embodying the same and having described the construction, purpose, and mode of operation thereof, what I claim as new and useful and of my own invention, and desire to secure by Letters Patent of the United States, is
