Specification of Letters Patent.
Patented Feb. 25, 1908.
Application filed ovember 16. 1907- Serial No. 402.496.
To all whom it may concern:
Be it known that 1, GEORGE GRACE, a citizen of the United States, residing at Wichita,
in the county of Sedgwick, State of Kansas, have invented certain new and useful Improvements in Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The present invention has reference to hydraulic pumps, and it aims, generally, to provide an exceedingly simple, readily-operated, and effective apparatus of that class by means of which large quantities of fluid can be transmitted under high pressure with the exercise of but little power. More particularly, however, the invention resides in the particular construction of the valve chest in which the severalvalve chambers are formed in the particular disposition of such chambers and in the particular arrangement with reference to each other and to the chambers, of the inlet and outlet passages and of the pas sages which connect the chambers. These as well as other features which form the sub ject matter of this case will be readily understood from the following detailed description, when considered in connection with the accompanying drawings in which,
Figure 1 is a plan view of the complete invention, the cover of the valve chest being partly broken away to illustrate the position of the valve chambers and valves. Fig. 2 is a side elevation thereof. Figs. 3, 4, 5, and 6 are sections taken respectively on the lines 33, 4-4, 55, and 66 of Fig. 1.-
Similar parts or features, as the case may be, are designated by corresponding reference numerals in the several views.
Referring more particularly to the drawings 7 designates, generally, the valve chest and 8 its cover; 9 the inlet or supply pipe; 10 the pumping mechanism, proper; and 11 the discharge pipe.
The valve chest, which is preferably in the form of a solid rectangular body, is provided with a series of four similarly-shaped valve chambers 12 which are formed in the upper portion thereof and register with correspondingly shaped seats formed in the under face of the cover 8, which latter is likewise solid and is secured by bolts or other removable fastening devices to the valve chest, the
joints between the chest and cover being rendered fluid-tight by any means preferred.
The supply pipe 9 has one end extending into the stream, or into a supply tank or cistern, while its opposite end is fitted in an inlet passage 13 formed transversely of the Valve chest below the plane of the bottom of the valve chambers and directly between the two central chambers, said passage terminating at its inner end in two branches 14 which extend in opposite directions at right angles thereto and communicate at their outer ends with vertical passages 15 which open through the centers of the bottoms of the last-mentioned chambers, communication between each of which latter and the adjacent end chamber being effected by means of a downwardly inclined. passage 16 formed through the corresponding wall between said chambers, each end chamber-being likewise provided with a vertical passage 17 Whose lower end communicates in turn with that of the corresponding passage 16. The upper ends of the vertical passages 15 and 17 are normally closed by upwardly-opening rectangular flap-valves 18,- one of which is disposed within each valve chamber.
The rear wall of each of the two central chambers has a downwardly-inclined passage 19 formed therethrough, the other end of each passage communicating with the lower end of a vertical passage 20 whose upper end opens through the upper face of the valve chest and has fitted therein the lower end of the corresponding arm 21 of an inverted U- shaped pipe which forms a portion of the pump mechanism proper 10. The lefthand arm of this pipe has a vertical extension 22 which forms the cylinder in which the plunger 23 is movable, the plunger being operated manually or by fluid power, according as preferred. The in-stroke or downward movement of the plunger is limited by an annular flange 24 formed interiorly of the extension 22, above the horizontal portion 25 which connects the upper ends of the arms 21.
Through the bottom wall of each of the two end chambers adjacent the rear end thereof is formed a transverse outlet passage 26 which extends rearwardly and downwardly through the rear wall of the valve chest, the outer end of each outlet passage having fitted therein, the free end of'the cor- I responding arm 27 of the U-shaped discharge upwardly, water will be drawn through the inlet pipe 9, the inlet passage 13 and its branches 14, and thepassages 15 which communicate therewith, into the two' central valve chambers, filling the same and the passages 16, the force of the water raising the valves in said chambers, the suction caused by such movement of the plunger holding the valves in the end chambers closed, to prevent the ingress of the water thereinto at such time. It will likewise be apparent that during the in-stroke or downward movement of the plun er, the valves in said central chamber wil be closed and will be held in position during the continuation of such movement, the water being forced out from said chambers into the end chambers. When the out-stroke, or upward movement of the plunger again commences, the lastmentioned chambers are emptied. and the water discharged therefrom through the pipe 11, the central chambers being refilled simultaneously withsuch discharge, the distance traveled by the plunger at each stroke being slight enough to effect the discharge of a practically continuous stream of water under high pressure.
In the appended claims, the central chambers which are filled directly from the supply-pipe will be termed inlet chambers while the end chambers from which the water is finally discharged will in like manner be termed discharge or outlet chambers.
What is claimed is 1. The combination, in a pump, of a valve chest provided with a pluralityof separate inlet and outlet chambers, with an interiorly located inlet passage having a separate branch communicating with each inlet cham ber, and with a separate outlet passage communicating with each outlet chamber, each inlet chamber communicating with the adj acent outlet chamber a valve disposed within each chamber; an operating mechanism com- .prising a U-shaped pipe having the free ends of its arms fitting in passages communicating with each inlet chamber, one of said arms having an extension, and a plunger movable in said extension; and a discharge pipe provided with a branch having its free ends fitted in each outlet passage.
2. The combination, in a pump, of a solid valve chest having a lurality of separate inlet and outlet chambers formed therein, and provided with an interiorly-located inlet passage having a separate branch opening-through the bottom wall of each outlet chamber, and with a separate interiorlylocated outlet passage communicating with each outlet chamber, each inlet chamber communicating with the adjacent outlet chamber;
a valve disposed within each valve chamber I an operating mechanism comprising a U- shaped pipe having the free ends of its arms fitting in passages communicating with each inlet chamber, one of said arms having an extension, and a plunger movable in said extension; and a discharge pipe provided with a branch having its free ends fitted in each outlet passage.
3. The combination, in a pump, of a solid valve chest having a plurality of separate inlet and outlet chambers formed therein, and provided with an interiorly-located inlet passage having a separate branch opening through the bottom wall of each inlet chamher, and with a separate interiorly-located outlet passage communicating with each outlet chamber, each inlet chamber communicating with the adjacent outlet chamber by means of an interiorly-located passage opening through the bottom wall of the latter; a valve disposed within each chamber for covering and uncovering the open ends of said passages; an operating mechanism comprising a U-shaped pipe having the free ends of its arms fitting in passages opening through the rear walls of the inlet chambers, one of said-arms having an extension, and a plunger movable in each extension; a U-shaped discharge pipe having the free ends of its arms fitted in said outlet passages and a laterallyprojecting discharge spout carried by said discharge pipe.
In testimony whereof, I affix my signature, in presence of two witnesses.
GEORGE GRACE.
