THEODORE DOXVNS, OF SPRINGFIELD, OHIO, ASSIGNOR OF ONE-HALF TO JACOB J. LISOH, OF SPRINGFIELD, OHIO.
SPECIFIJATION forming part of Letters Patent No. 731,549, dated June 23, 1903. Application filed February 18, 19 02. Serial No. 94,676. (No model.)
To an whom it may concern: Be it known that I, THEODORE Downs, a citizen of the United States,residing atSpringfield, in the county of Clark and State ofOhio, have invented a new and useful Pump, of which the following is a specification. This invention relates generally to pumps, and specifically to that class employing hollow pistons. The object of the invention is to provide a pump that shall combine simplicity and economy in construction, durability'and efficiency in use, and in which the parts shall be so constructed and assembled as to permit of ready repair in case of damage or breakage. With these and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a pump as will be hereinafter fully described and claimed.
In the accompanying drawings, forming a part of this specification, and in which like numerals of reference indicate corresponding parts, there is illustrated a form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage Without departing from the spirit of the invention, and in the drawings Figure 1 is a view in elevation, partly in section, of a pump characterizingthe present invention. Fig. 2 is a view in sectional elevation, on an enlarged plan, of the lower section of the pump. Fig. 3 is a horizontal sectional view, on an enlarged scale, taken on the line 3 3, Fig. 1.
piston arranged in the order occupied when assembled and displaying clearly the construction of each part.
Referring to the drawings, and particularly to Fig. 2 thereof, 1 designates the pump-cylinder, provided at its upper end with a gland 2, in which works the hollow piston-rod 3, the gland being disposed upon the top of a cap 4, constituting a portion of the cylinder, the cylinder and cap being provided each witha flange 5 and 6, respectively interposed bolts 8.
Fig. 4 is a perspective detail view showing the different parts of the by a packing-ring 7 and held assembled by To the lower end of the cylinder is connected bya threaded joint a casting 9,
said casting and cap being each provided with a lateral extension 10 and 11, respectively, in which are housed inlet- pipes 12 and 13, respectively, carrying valves 14 and 15, that open into the pump-cylinder near its terminals, the pipes 12 and. 13 being threaded into unions 16 and 17, connected by a vertical pipe 18,the unions bearing against the ends of the extensions 10 and 11 and being held in engagement therewith by tie-bolts 19,pa cking-rings 20, interposed between the opposed 55 faces of the unions and extensions, serving to present water-tight joints at these points. By securing the pipe 18,withits complemental parts, to the cylinder in the manner described removal therefrom, when necessary, may be easily effected without disconnecting any of the parts of the said pipe.
The hollow piston-rodB, which may be of the usual or any preferred construction, carries at its lower end a piston comprising two valve- seats 21 and 22, two sucker-leathers 23 and 24:, the rims of which are oppositely disposed with relation to each other, a spacingring 24 for holding the suckers the proper distance apart, two valves 25 and 26, disposed against the upper and under faces, respectively, of the valve-seats, a spring 27 for holding the valves against their seats, and two threaded collars 28 and 29, the former of which is turned into engagement with the upper side of'the valve-seat 21 and the latter against the under side of the valve-seat 22, that portion of the piston-rod'engaged by the piston being threaded to engage the locking- collars 28 and 29. As willbe seen by reference to Fig. 4:, the
The means for imparting reciprocatory motion to the hollow piston-rod comprises two levers 36, fulcrumed intermediate of their ends upon studs 37, projecting laterally from a collar 37, clamped on the hollow piston-rod, the longer ends of the levers being pivotally connected with the upper terminals of a pair of links 38, the lower terminals of which are pivotally connected to brackets 39, carried by stay-plates 39, secured at their terminals, respectively, to the flange 5 of the cylinder and a flange 40, arranged at the lower end of the water-receiving chamber. The shorter arms of the levers 36 are connected by a cross-rod 41, to which is secured the lower end of the pump-rod 42, the upper end of which is associated with a pump-handle 43 in the usual manner. The association of the levers with the studs 37 is to be such as to prevent any binding between the pistonrod and the gland of the waterreceiving chamber.
The operation of the pump is as follows:
Upon the upstroke of the piston water will.
be drawn into the feed-pipe 44, that extends into the well, and into the inlet-pipe 13, open-. ing the valve of the latter and allowing water to escape to the pump-cylinder. The water through the discharge-spout in the usual manner. On the downstroke of the piston the valve closes the inlet-pipe 13, and the water contained in the cylinder below the piston forces the valve 26 upward from the valve-seat 22 and passes through the ports into the hollow piston-rod, and thus upward and out through the discharge-spout. At the same time that the water below the piston is being forced out the suction caused by the downstroke opens the valve 14 and draws water into the cylinder above the piston, and so on, water being discharged and taken into the pump-cylinder at each stroke of the piston-rod.
It will be seen from the foregoing description that while the pump of this invention is composed of but few parts these are so constructed and assembled as to present a pump that will at once be capable of long continued use without getting out of repair, that will be certain and effective in operation, and that in case of injury may be readily and easily repaired.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
In a pump, the combination with a pumpcylinder having lateral tubular extensions, of connected valved inlet-pipes slidably mounted in the extensions, and means for clamping the inlet-pipes in position.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
THEODORE DOWNS.
