iGlIYSIDENSTRICKER AND JOHN WALTER MILLER, or MOUNT CLARE, wnsr VIRGINIA.

WOODEN PUMP.

the county of Harrison, State of West Virginia, have invented a new and useful Wooden Pump, of which the following is a specification.

I The subject of this invention is a wooden pump of the reciprocating solid piston type,

I and the objects of the invention are, first, to provide a pump with a minimum of metal parts exposed to the fluid, second, to provide pump valves free from valve stems or springs, third, to provide valve seats which may be readily removed and replaced without the use of screws, bolts or other fasteners, fourth, toprovide a simple, durable, and eflicient .pump. With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination; and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the'invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of the invention. I

A practical embodiment of the invention is shown in the accompanying drawings, wherein:

Figure l is a view in side elevation of a pump constructed in accordance with this invention, a portion of the pump beingin section.

Fig. 2 is a cross section on the line 22 of Fig. 1.

.Fig. 3 is a longitudinal line 3-3 of Fig. 2.

Fig. 4 is a longitudinal section on the line 4-4 of Fig. 1.

Fig. 5 is a longitudinal section on the 40 section on the line 5 5 of Fig; 1.

Referring to the drawings by characters of reference:

The ump is shown at P, while 0 indicates t e operating mechanism for the pump.

The pump proper consists of a wooden block of any suitable form, but here shown as a rectangular prism which is provided with one or more longitudinal bores 1, two

being shown in the present instance, for the reception of solid cylindrical pistons 2. The

pistons 2 are preferably formed of some suitable wood such as black gum which wears well and becomes extremely smooth and slippery.

A duct 3 communicates with and leads downwardly from each bore 1 to a valve casing or chamber 4. As will be observed the duct 3 leads into the valve chamber 4 at the top and to one side thereof. Each 6 valve chamber 4 communicates through a transverse bore or duct 5 with a valve casing or chamber 6.

An intake port 7 is provided in one face of the pump which communicates through the horizontal bore 8, which extends toward each side of the pump from the intake port, with the valve chambers 4C, the bore 8 having an angled portion 9 at each end thereof to communicate with said chambers 4.

The valve chambers 5 communicate through connecting duct 10 with a discharge port 11 which is situated in the face of the pump opposite to that in which the intake port is located.

' Each valve chamber 4 and 6 is provided,

at what might be termed its intake side, with a groove at the upper and lower edge of the wall which grooves are adapted to receive the edges of a plate or valve seat 12 which is centrallyapertured to provide an inlet port. The plate 12 is formed with a cage '13 extending therefrom and preferably cast integral therewith. Within each cage is loosely mounted a valve 14 which is in the form of a roller or disk, and which is adapted to seat on the plate 12.

A similar metal plate 15 engages opposed faces of the pump and each plate is apertured to aline with the intake port 7 or discharge port 11. The apertures of the plates 15 are threaded to receive the intake pipe 16 and outlet or discharge pipe 17 Packing 18 of rubber or other suitable material is interposed between each plate and the pump surface and the opposed plates are bound upon the pump by through bolts 19, or otherwise.

As will appear most clearly in Figs. 2, 4 and 5, each pair of chambers 4: and 6 open at opposed faces of the pump, and these openings are closed by plates 20. A rubber packing 21 is interposed between each plate 20 and the pump and the plates 110 are bound in place upon the pump by through bolts 22.

bars 26 are secured. to the leg of each yoke.

- lows: The S shaft 29 is revolved causing V The operating mechanism is mounted on a plate 23 which is secured to the upper end of the pump by screw bolts 24 or otherwise. Opposed yokes 25, only one of whichis shown, rise from the plate 23 and guide through the pitman 28, reciprocation of therblocks 27 and pistons 2. On the up stroke of each piston, a vacuum will be produced in the bore or cylinder causing fluid to flow through. intake pipe 16, passage 8 and 9 to chamber 4, duct 3, and bore 1. Upon downward stroke the valve 14: in chamber 4 will be closed and fluid will be forced from the bore or cylinder 1, through duct 3, chamber 4 and bore 5 to chamber 6.

This will unseat valve 14: in chamber 6 and force fluid throu h passage 10, port 11 and discharge pipe 1 V The valve seats 12, with their cages are formed of bronze or other metal little affected by acidulated water. When, however,

theseseats and, cages becomecorroded they 7 may readily be replaced byv removing the plates 20, withdrawing the corroded valve seat and driving a new one in place.

Having described the invention, what is claimed as new and sought by Letters Patent, is: V t

1. A pump, comprising the combination of a single integral wooden block having a longitudinal cylinder bore, a passage to form an extenslon of sald bore, a transverse passage through the block with which the'first mentioned passage communicates, said trans verse passage having enlargements forming valve chambers, one side of each of said enlargements forming a valve seat, a substantially cylindrical block loosely movable in said enlargement and forming a valve, a guide for each block and a removable plate secured to the side of the wooden block adapted to be removed to allow access to said valve chambers, a wooden piston in said cylinder bore, and means for actuating the piston.

2. In a pump, the combination of a single integral wooden block forming" a pump body, said block having parallel cylinder bores, passages forming extensions of said bores, transverse passages communicating therewith and having enlargements at each side of the point where first mentioned passages meet the second named passages, said enlargements forming valve chambers, a valve in each of said chambers, said block having openings in opposite sides, said gassages, connected with each of said transverse passages, said enlargements opening outwardly at theside of the block, removable plates, and acid resisting packing between the plates and the side of the "block for closing said valve chambers while allow ing access thereto, solid wooden ,pistons in each of said cylinder bores,-and means for actuating the pistons, V

In testimony that .we claim the foregoing as our own, we have hereto afliXed our signatures in the presence of two witnesses. v
