PUMP,
SPECIFICATION forming part of Letters Patent No. 309,493, dated December 16,1884.
Application filed March 31, 1884. No model.)
To (LZZ whom, it may concern.-
Be it known that I, THOMAS Rosn, a sub ject of the Queen of Great Britain and Ireland, and a resident of Brooklyn, New York, have invented certain Improvements in Pumps, of
which the following is a specification.
My invention relates to an improvement, de-
scribed and claimed hereinafter, in that'class of pumps in which the fluid to be forced volrc nntarily enters the barrel through openings in the same when the piston is at the limit of its inward movement; and the main object of my invention is to so construct a pump of this class that, while it can be used for pumping r 5 water and other liquids, it shall be especially applicable to the pumping of gas.
In the accompanying drawings, Figure l is a vertical section of a pump illustrating my invention, and Fig. 2 a sectional plan on the line 1 2, Fig. 1.
The pump has, in the present instance, two cylinders or barrels, D D, the lower portions of which project into an inlet-chamber, H, contained within a casing, A, which is supported 2 5 by suitable legs, 13 B, and into which extends a shaft, I, carryingacogwheel, X, which gears into the guided racks M M, one sccu red to each piston K.
As regards the general structure of the pump,
0 it forms no part of my invention; hence it will sut'fice to remark, therefore, that a vibrating motion is imparted to the shaft I, and consequently a reciprocating motion in contrary directions to the two racks M M and their pis 5 tons, the air, water, or gas admitted to the cylinder being forced through the valve-chests E and through the force-pipe T. There area series of openings, n, in each barrel of the pump, and when the piston of each barrel is at the limit of its inward movement these open- 40 ings afford a direct communication between the inlet-chamber and the interior of the barrel. The pistons are without valves, and can be so operated that the terminus of the outward stroke of each piston shall be very near to the outer end of the barrel without being in absolute contact therewith. This is of espe cial advantage in pumping gas, as very little of the latter can remain in the barrel of the piston when it reaches thelimit of its outward o stroke.
I am aware that a pump-barrel has been made with lateral openings for the admission of water when the piston is at the limit of its inward stroke, as in Patent No. 181,144, August 15, 1876, but in this case the piston or bucket was perforated and provided with valves, an arrangement which would frustrate the main object otmy invention.
I make no claims to the general structure of the pump, as it is similar to that described in the application of N. \V. Oondict,'Serial No. 126,008, filed March 31, 1881.
I claim A pump in which the following elements are combined, namely: first, an inlet-chamber, H; second, a barrel having aseries of lateral openings communicating with the said chamber; third, the valveless piston K and, fourth, the discharge-valve, all substantially as set forth. 7c
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
THOMAS ROSE.
