To all whom it may concern:

Be it known that I, RoscoE BEAN, of Springlield, in the county of Clarke and State of Ohio, haveinvented certain new and useful Improvements in Pumps and I do hereby declare the following to be a full, clear, and exact descrip skilled in the art to whichit appertains to make companying drawings, and to the letters of refthis specification. a i

The nature of my invention consists in the construction and arrangement of a pump, as will be hereinafter more fully setforth; and ithas for. its object, first, to provide a means whereby the cylinder or main body thereof may be suspended below the sustaining-platform and, further, to so construct the suspending device or devices-that they will form an airchamber and a dischargefpipe, and also a support for the handle-standard; and, secondly, to soconstruct and arrange its several partsthata continuous and even'tl'ow of water is obtained, which result is due to the inequality in the diameter of my cylinder and the use of two pistons on the same actuating-rod, when taken or usedin connection with an airchamber orchambers communicating with the cylinder at a point intermediate of the pistons.-

In the drawings I show two air-chambers formed of the actuating-rod and the other of the tubular supporting-piece C. When I use rod, I may then form the supporting-piece G of as may be In the accompanying drawings, Figure '1 is a side elevation of my improved pump, and Fig. 2 is a central vertical section of the same.

A represents the cylinder of my pump, formed with two branches or projections, a. a, with openings in the top. of the branches comrnunicating with the interior of the,- cylinder. In one of the openings is screwed the dischargepipe B, and'in the other a pipe or rod, 0. If this latter is a tube, its upper end should be closed forming insnch a case an air-chamber as a means of support, in connection By this means the pump can be easily raised or lowered, as may be required, without loosening the platform from the curb or other support, or it maybe permanently fixed. E-represems the hamlle-standarQ-haVin-g- Q its lowerends forked and formed with sleeves orsockets d d, through which the parts B O are passed, and the standard then fastened by means of the set-screws c e. This standard can thus be adjusted to any height desired and easily fastened in position.

G is the pump-handle, pivoted in the top of the sItandard E, and connected to the pump r0 The actuatingarod [is a tube closed at its upper end and arranged to attach to the pumphandle at its upper end, carrying at its other or lower end thepistons J and J, so disposed thereon as that the point of communication with the air-chamber will come betweenthe said pistons. f

Between the pistons there is an'open-ing,'i, in the actuating-rod, which forms an air-chamher, by whichcommunication is bad with the cylinder, so that the pressure of air will regu- 85 late the flowjof water.

ThecylinderAmay beconstructed,asshown, of nneqnaldiameter, thelower or suction bucket working in the large bore and the upper or force bucket in the smaller bore. The object of this arrangement is that while the lower bucket is' drawing water from the bottom, at the same time it is forcing one-half of the water into the upper part ofthe' cylinder and the other half out at the spout. In returning, the balance of the water is discharged, making, in con nection with the air-chamber in the pump :gtnatingrodl, an even stream or flow of wa- Itwill be seen that in the pump as thus 0011- too 5 rarrgement adding greatly to the compactness of the whole.

Theadjustable handle-standard, forked at its lower end, and formed with sleeves or socketshavingset-screws, as described, in com. bination with a pump having upwardly-projecting tubes, or one tube and one rod, substantially as herein set forth.

3. In a pump, ahollow rod, I, used as an airchamber, in combination with two buckets of unequal size attached to it, and an air-discharge between the two buckets, substantially .as and for the purposes herein set forth.

4. The hollowv rod I, having opening i, and provided with the pistons J and J within the cylinder A, in combination with the pipes 0 and B, one. serving as an auxiliary air-chamber and the other as an exit-pipe, and the two as supports for the operating mechanism of the pump, 5.

7. In apump, thecornbination of a suspended cylinderhaving two chambers of unequal diameters and a. supporting tubular frame forming an extended air-chamber, and a water-discharge medium, substantially as shown.

8. In a pump, the combination of a cylinder having two chambers of unequal diameter, a tubular actuating-rod having pistons adapted to work in the respective bores of the cylinand 'an'anxiliary or outer air-chamber, the rod and chamber communicating with the cylinder between the pistons, as shown.

.16. In a pump, the combination of a platform-flange having openings for the passage of the actuating-rod and the supports, and the latter connecting with the lower part of the pump, as shown.
