Specification of Letters Patent.

Patented Aug. 17, 1915.

Application filed May 9, 1914. Serial No. 837,963.

To all whom it may concern Be it known that 1, LEE Roy APPLEGATE, a citizen of the United States, and resident of Seattle, King county, 'Washington, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

shown my invention embodied in the form which is now preferred by me.

Figure 1 is a front elevation of the pump showing one end thereof in vertical section. Fig. 2 is an end elevation showing the base and a portion of one cylinder in section. Fig. 3 shows one of the valves in perspective. Fig. 4 is a central transverse sectional elevation. the cranks and pistons being omitted. Fig. 5 is a plan view of the base, with portions of the valve chamber covering plates removed, and with the cylinders in place. Fig. 6 is a bottom plan view of the plate which engages the upper ends of the cylinders.

The base 1 contains therein a series of transverse channels 10, the number of'which corresponds with the number of cylinders used in the pump. Each of these channels has an upwardly extending opening 11 designed to communicate with the cylinder which is employed in connection therewith. The upper surface, of the casing surrounding these openings is slightly recessed to form a ledge 9 which receives and supports the lower end of its cylinder 3. The cylinders are preferably made as plain tubular shells.

At each side of the casing channels are formed connecting all of the transverse channels 10. The channel 18 at one side of the casing constitutes an inlet header from which the water is supplied to all the transverse channels 10. The channel 13 which is at the opposite side of the base communicates with the opposite ends of all the channels 10, and. constitutes the discharge header. Between the connection with the cylinder and the inlet header each transverse channel 10 is provided with a chamber 12 which extends upwardly to the upper surface of the base and constitutes a valve chamber. In this chamber is placed a valve 2 which is adapted to close the port 19 which connects channel 10 with the inlet header 18. In the wall of the casing lying between the valve chamber 12 and the inlet header 18 is formed a slot of T-shape, extending from the upper surface of the casing downward to a point close to the port 19. This slot is made with the stem of the T communicating with the valve chamber 12. The valve which is used is shown in perspectivein Fig. 3. This consists of a plate 2, of a size and shape to satisfactorily close the port 19, provided at its upper edge with a curved or elbow-shaped arm 20, havingat its end a transverse bar 21, which arm and head are adapted to enter the T-shaped slot 22. At the opposite end of the transverse channel 10 the port 1 1 which communicates with the discharge header 13 is closed by a valve of the same construction and mounting. An inlet and outlet valve of this character is provided for each of the transverse channels 10.

The inlet header 18 and the valve chambers 12 are closed at their upper side by a plate 15 which is bolted down thereon, and the outlet header 13 is closed in a similar manner by a plate 16. Plate 16 is provided with an opening for the reception of the discharge pipe 8.

A standard 5 is secured ateach end of the base, and extends upwardly, providing hearing 61 for the crank shaft 6. This standard has a cross bar 50 located at a point approximating in level to that of the upper ends of cylinders 3, preferably being slightly lower than the ends of the cylinders. A plate 4, shown in bottom plan View in Fig. 6, is provided with openings 40 having recesses 11 in the lower surface of the plate adapted to receive the upper ends of the cylinders 3. This plate has ends 12 which project between the side bars of the standard 5 and over the cross bar 50, to which the plate is bolted so as to be drawn strongly down upon the ends of the cylinders.

Where several cylinders are used, as shown in the drawings, central holding-down bars 4% should be employed, these passing through the plate and being anchored in the base 1. lhese bolts may also be employed to-hold down a short standard 52, which contains a central bearing 62 for the crank shaft.

The crank shaft 6 is provided With a series of cranks 60, one for each cylinder, upon the bearings of which are journaled the connecting rods 31, the other ends of these rods being pivoted in the pistons 30. This crank shaft may also be provided With a shell 63, or any other suitable means for turning the same.

The construction above described is one Whichis very simple and cheap to make, and one which is easily maintained in good Working condition. The type of valve employed is one Which provides a large opening With a small movement, is cheap to make, and Will close quickly.

What I claim as my invention and desire to patent is:

I l. A multiple cylinder pump having a baseprovided With a series of shallow, cylinder-seating recesses arranged in a central row, a series of Water conduits extending transversely of said roW of cylinder seating recesses, one below and communicating With each cylinder seating recess, a valve controllingeach end of each of said transverseconduits, the upper Walls of said conduits 'hav-.

ing openings over and giving access to each of said valves, said base having header channels connecting the ends of sand transverse conduits and provided With means for connecting with supply and discharge pipes, and plates for closing the openings into said channels: 1

2. A multiple cylinder pump comprising-a base .hav-ingsupply and discharge ports therein and an alined roW of cylinder seating recesses in its upper surface, each communicating With a separate port, a series of plain tubular cylinders lacking end closures, each seating in one of the said recesses, a platehaving a corresponding series of alined cylinder seating recesses placedupon the upper end of the cylinders and having holes therethrough communicating With the cylinder bores, and tension bolts connecting said plate With the base. 7 i

3. A multiple cylinder pump comprising a base'having supply and discharge ports therein and an alined row of cylinder seat ing recesses in its upper surface, each communicating With a separate port, a series of plain tubular cylinders lacking end closures,

each seating in one of the said recesses, a plate having a corresponding SEHQSVOI? alined cylinder seating recesses placed upon the upper end of thecyhnders and havlng holes therethrough communicating with the cyl base havingsupply and discharge ports and. controllingvalves therein and, having an alined row of cylinder seating recesses in its upper face and openings connecting each of said cylinder seats'with its respective ports in the base, a series-of cylinders each con sisting of a' plain tubular shell fitted, each to its respectlve seat, a standard extending upward from the base at each end of the row of cylinders, and provided With a shaft bearing at its upper end and a ledge at a level corresponding-to the upper ends; of the cylinders, a plate having cylinder jcentering and holding means extending over the row of. cylinders and having holes therein correspondingwvith the cylinder bores,

the ends of said plate being clamped down upon the ledges ofthe end standards, tension bolts connecting the central portion of saidplatewith the base, and a shaft bearing member supported from the saidplate and secured bysaid tension bolts. I

5. A pump having a base provided With a channel communicating With the pump cylinder and at each side of this connection having a valve chamber extendingupvvardly and opening at the upper surface of the base, one side vvall of said chamberconsth tuting a valve seat, said Wall, above the port therethrough, having a T-shaped recess extending from the upper surface of the 7 base downward With the'base ofzthe open ing into-the valvechamber, and valves each having an elbow-shaped central arm terminating in a transverse bar adapted to fit'into' the recess in the chamberWall, and plates closing the upper opening'of said chamber.

In testimony whereof I have hereunto aflixed my signature. this 1st. day of May, 1914;. 1
