FORCE-PUMP.

SPECIFICATION formingpart of Letters Patent No. 272,616, dated February 20, 1883. Application filed September 4, 1881?. (No model.)

To all whom it may concern:

Be it known that l, ALLEvr ANNIBALE, a citizen of the United States ot' Anierica,re siding at Chicago, in the county of Cook and State of lllinois, have invented certain new and useful Improvements in Force-Pumps, of which the following is a specification.

My invention relates to force-pumps; and it consists in a pump of peculiar construction, whereby Ii'orce the water from the pump by gravitating pistons working in chambers revolving around a' common axis; and, also, in certain novel details of construct-ion, which will be more fully described hereinafter.

In order to enable others skilled in the art to which myinventiou appertains to make and use the saine, I will now proceed to describe its construction and operation, referring to the accompanying drawings, in which- Figure 1 is a perspective view of my improved force-pump. Fig. 2 is a longitudinal section through the wheel containing the piston-chambers. Fig. 3 is a vertical cross-section of my pump; and Fig. 4 is adetail side view of part of the cylinder-wheel,showing the mode of operating the inlet-valves.

A represents a circular casting or wheel, having four radial chambers, A', separated at their inner ends by webs a a.

B B' are plates covering the sides of the wheel A, and secured thereto by any suitable means. The plaie B is provided on its outer surface at the center with a chamber, b, which has cast with or secured to it the hollow shaft b'. This shaft b ispassed through a stuing-box, b2, ot' any desired form, into the end of a pipe, c, which is bent upward and carries the air-chamber C. From the top oi'- this air-chamber extends the outletpipe C'. The pipe c is, just below the air-chamber, provided with a valve, c', and is supported and kept in place by a brace, c2, as shown.

The outer ends of the radial pump chambers or cylinders A' are closed by plates A2, secured to the periphery ofthe wheel A, and provided in their centers with openings connected by pipes A3 with thechambcr b. These pipes are each supplied with a valve, a', opening outward.

The plate B', secured to the opposite face of l the wheel A, is provided in its center with a shaft, d. The plate is also pierced by openings d',communicaling with each of the radial chambers A','and over each opening is a sliding plate, D, having a beveled head, D',

and an o renin d2, corres rondine in size and s l n shapewith theopcning d' in the plate B'. This valve or cnt-on" plate D slides in guides di d3 upon the plate B', and is provided on its rear end with an arm, e, sliding in a guide, c', and surrounded by a coiled spring, e2, as shown in Figs. 3 and 4, which'operates to force the cuto outward and project it considerably beyond the periphery ofthe wheel A. v

Each of the radial chambers A' is provided with a piston-head, E, fitted loosely therein, and these pistons are connected in pairs by rods f f, as seen in Figs. 2 and 3, passing through the webs a a.

G is a. bag or casing of' canvas, rubber, or any suitable flexible material, secured to the edges ofthe pistons E at one end, and at the other end under the overlapping edges of the caps or plates A2. Each piston is pierced throughtits center, and provided with an outwardly-opening valve, g, as seen in the drawlngs.

'.I'he shafts b' d rest in journal-boxes on the upper edge of a trough or box, H, as shown, in which the wheel A revolves. One end of this box is dared outward, as seen at li, Fig. 4, in order to form a canfway for opening the cutoff valves D.

In operation the whole device is immersed in water, in a well or any place from which water is to be drawn. The water, ventirely covering the box H and surrounding the wheel A within said. box, enters the lowest chamber A', behind the piston, (which is at its lowest point,) through the openings in the cut-off D and plate B', which now register. The wheel A being now caused to revolve, the slide-valve D, when it is clear ot' the box H, will be thrown out, cutting otf all further entrance of water, and as the wheel revolves till the piston-chamber is at iortylve degreesinclination, the piston E, by its own weight, begins to slide back, the valve g opens, and the water is admitted to the bag G. The chamber passes its highest point and begins to descend, and when it ICO reaches the angle named in its downward motion the piston E falls again,forcingthewater in the bag G, through the pipe A3, chalutier b, hollow shaft b', and pipe c, into the air-chalnberC, whence it passes ott' through the outlet C'. In the meantime the slide D has been forced back again by the vcam-surface h, and the pistonchamber retills. This process takes place 'in all of the. pistonchambers, and causes a continuous volume of water to be forced from the pump. `Theforce of the water driven from the pump and its volume are only limited by the size ofthe chambers A' andthe weight ofthe pistons It will be seeu that the water is forced out by a power equal to the combined weight of the two piston-heads E coupled together, and as these pistons are made a little smaller than the chambers in which they work they will move with the smallest degree of' friction, while at the same time n0 leakage of water occurs. by reason of its being admitted to the bags G before being forced out. Greater power may be obtained by increasing the weight of the pistons, either by enlarging them or by forming them hollow7 and filling them with lead.

As all of the radial water-chambers A' are always filled with water, either before or behind the piston-heads, the wheel is balanced and always revolves with a steady motion.

The shaft d is provided with a. gear or chain wheel,to which power may be transmitted from any motor found most convenient or desirable.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Pateiit, is-

1. In a rotary force-pump having two or more piston-chambers, the gravitating pistons connected together in pairs, substantial-ly as shown and described.

2. In a rotary force-pump, the combination,

bered wheel A, provided with ports d', andthe l sliding cut-otfs D, having heads D', openings d2, and spring c2, substantially as shown and described.

4. In a rotary force-pump, the radial pistonchambers A', having inlet-ports d', in combination with the spring-actuated sliding cut-ol` D, having a similar port, (Z2, substantially as herein shown and described.

5. A rotary force-pump consisting, essentially, of a radially-chambered wheel having inlets for water, gravitating pistons connected in pairs, an air-chamber having an outlet-pipe, intermediate pipes connecting the radial pistonchainbers and air-chamber, and a frame or box in` which the pump-wheel is supported and revolved, all constructed and arranged to operate substantially as herein shown and described.

G. In a rotary forcepump, the combination of the box H, having carnway h, the wheel A, having radial chambers A', provided with suitable ports, the valved pistons E E, connected in pairs, the flexible bags Gr G, chamber b, ra-

dial pipes A3, sliding cut-offs D D, air-cham` ALLEVI ANNI BALE.
