To all whom it may concern:

Be it known that 1, WILLIAM A WHITING, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Pumps, of which the followingis a specification, reference being had therein to the accompanying drawings.

The invention has particular reference to a weight-power force-pump; and it consists in the novel formation of the pump and in the peculiar construction of the valve-chest and the arrangement of the valves therein, as will be more fully hereinafter vdescribed. and shown in the drawings, in which- Figure l is a section through the pump, taken on line :c ce, Fig. 2. Fig. 2 is a side elevation of the pump, partly in section. Fig. 3 is a plan view, partly in section; and Fig. 4 is a perspective view of one cylinder and a portion of the valve-chest, the parts being detached.

The reference-letter A designates the basesection of the pumping apparatus, upon which is mounted an upright skeleton framework B.

C designates a series of cylinder-heads, preferably three in number and arranged in suitable recesses formed for the same in the base-section.

D represents the cylinders, corresponding in number to the heads and secured to the latter by bolts c, the cylinders in turn being secured to the base of the framework by bolts h.

E represents the pistons of usual construction within the cylinders, and F the pistonrods, secured at their upper ends to the crossheads G.

F designates guide-rods arranged in pairs above the cylinders, the lower ends of each pair being secured to a cylinder and the upper ends to cross-bars H, as plainly shown in Figs. l and 2.

The reference-letter I designates the main drive-shaft of the pump, journaled in suitable bearings .I in the top of the frame, and K represents cranks so arranged upon the shaft as to work on thirds. Each crank is secured to its respective piston-rod by means of a connecting-rod L.

The cylinders thus described are of the usual construction, with the exception that each is provided with a iiat face M, through which the cylinder-ports c and d extend.

O represents a laterally-projecting section extending across the three cylinders and carrying at one side a tlanged portion P, adapted to be bolted to t-he cylinder-faces. Secured to the outer side of the lateral section is my improved valve-chest Q, of the following construction: In configuration the chest is oblong and the interior thereof is divided into three substantially equal longitudinal compartments e, f, and g by means of suitable partitions, such as h h. The lower compartment is provided with inlet-ports t', preferably at each of its ends, and j designates similar ports in the ends of the upper compartment, through which the Water is discharged. rIhe middle compartment f of the valve-chest is divided, by means of a series of vertical partitions la, into six compartments, such as l, and in each compartment is arranged a gravity-valve, such as m. The portion of the partition f forming the lower wall of each middle compartment is apertured to receive a valve-seat in the form of a bushing, an'd the upper partition e is apertured in a similar manner to receive similar bushings, arranged directly above the bushings inthe middle compartment. Seated in these bushings are the gravity-valves m referred to, comprising the valve proper, m', and the triangular stem or shank m2. Each of the compartments Z is provided with a port, such as ct', which registers with one of the ports in the cylinder adjacent to the compartment. The front of the valve-chest is formed of three sections, such as A', the sections being adapted to be detachably secured to the front of the chest by suitable bolts, so that access can be had to the valves for any one of the three cylinders without the necessity of removing the entire casing or chest front. The top of the valve'chest is formed in a like manner, openings B' being formed therein, which are adapted to be covered by plates C. The valves in the upper longitudinal compartment may be placed in their seats either through the top of the valve-chest or through the front. The lower set of valves are adapted to be inserted through the front only.

To equalize the pressure, I provide for the IOO valve-chest an air-chamber D' and arrange said chamber preferably upon the middle top section of the valve-chest, as plainly shown in Fig. l.

Mounted in the top of the frame is a drum G', having wound upon it the cable Q', to which is attached the weight (not shown) for operating the pumps. At one end the drum is provided with a sleeve A2, journaled in a suitable bearing on the frame, and B2 is a shaft upon which the drum is loosely mounted,having one end journaled within the sleeve and the opposite end in a bearing similar to the sleeve-bearing.

C2is a pinion fixed to the drum in any suitable manner, carrying a pawl O'.

D2 is a ratchet upon the shaft B2, in operative relation to the pawl, and H' is a gearwheel on the end of the shaft last referred to, engaging a similar wheel I' on the main driveshaft I.

It will be obvious from the description of the drum and its connections with the driveshaft that it may be rotated in one direction to raise the weight without operating the pistons and that when turned in the opposite direction by the weight the pumps will be operated.

I have shown one type of mechanism for raising the Weight, consisting of a gear-wheel J', fixed to the sleeve on the drum and meshing with a pinion K' upon a stub-shaft L', and a crank M' for actuating the piston. Other means may be employed, however, whereby the drum may be actuated by horse-power. To permit of the weight being raised in this manner, I employ a second drum E2, journaling the latter in the framework below the weight-drum, and form a gear connection between the drums by securing to the end of the drum E2 a gear-wheel F2, adapted to engage the pinion C2. A cable, such as Q2, may

be wound upon the drum E2, through the agency of which the latter drum may be actuated.

In operation the apparatus is placed in convenient relation to the water that is to be pumped, and the valve-chest is provided with suitable pipes (not shown) extending from thc inlet-ports in the chest to the water-supply. Upon the action of the pumps the water is received, first, in the lower compartment of the valve-chest, passes in the usual manner through the inlet-valves into the cylinders, is discharged from the cylinders into the npper compartment, passes out from the latter through the discharge-ports, and is conducted in any suitable manner to the points desired.

While I have shown and described a preferable construction of pumping mechanism, I do not desire to be limited to the same, as various modifications may be made in its formation without in any manner departing from the spirit of my invention.

What I claim as my invention isl. In a pumping apparatus, the combination with the frame, of the cylinders and the pistons, of a drive-shaft connected to the pistons, a drum carrying at one of its ends a sleeve journaled in a bearing in the frame, a shaft extending through the drum and having its ends journaled in said sleeve and frame, a pawl upon the drum, a ratchet upon the shaft in operative relation to the pawl, a gear connection between the drum and drive-shaft, and a weighted cable for operating the drums.

2. In a pump, the combination with the valve-chest having a plurality of removable front sections, and detachable top sections corresponding in number to said front sections, the chest being provided with inlet and discharge ports, an inclosing casing constituting an air-chamber mounted upon one of the top sections and communicating with the interior of the valve-chest, valves within said chest adjacent to the removable sections, the cylinders having ports leading into the chest, the pistons, and means for operating the pistons, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM A. VVHITING.
