IMPROVEMENT IN PUMPS.

Tht: Schedule referred to in these LettersPatent and making part Ofthe same.

To all lwhom. fit may concern Beit known that I, R. W. Cnousn, of Westminster, in the county of Carroll, and State of Maryland, have invented a new and improved Pump; and I do herebyideclare that the following is a full, clear, and exact description of the construction and operation of the saine, reference'being .had to the accompanying drawings, making a part oi' this specification, in which lmy invention is represented by a side view, a portion oi' the wall being broken away.

The. object of this invention is to provide forpublic use a double-acting pump, so constructed that it can be conveniently repaired when the packing 'becomes worn or injured.

,ln the drawings- A represents the upper chamber, and v B', the two cylinders connected with it, there being ltwo valves, not shown, between tbe upper ends of the cylinders and the lower side of chamber A.

rlhc plunger-s are worked Vat the lower end of the two 4cylinders by means of rods or straps G C', extendingdowny alongside of or around the `cylinders from a double-crank shaft, l).

The rot-ation of the shaft gives an alternate reciprocating action to the rods and plungers, as will be at once understood ii'om the drawings, thereby forcing the water up through the cylinders into chamber A, and thence discharging it through the pipe E.

The plunger consists of a disk,`M, fitting into the lower end of the cylinder, and havingan opening, an, through its centre.

.A curved brace-yoke, n, is suitably attached to the under side of the disk, and a vertical standard, o,

screws into the latter at its centre, the vlower end of the standard terminating in two lugs o' o', between which the lower end of rod C or C passes, and tok which it-is fastened by a removable pin or bolt, b.

An arched dome, W, having apertures through its sides, is attached to the upper, side of disk-M, enclosing between it and the disk a ball-valve, I.

'A stem, s, projects vupward from the top of the arch orcover W, and screws into a guide-plate, T, having suitable openings in it to let tbe water pass through.

rlhis whole apparatus, consisting of disk M, yoke n, standard o, arch W, valve I, and guide T, constitutes 1n y improved plunger, its advantage over all others -being that whileJ it runs .easily in the cylinder, and operates i perfectly, its ball-valve not being liable to get out of order, it can, by removing the pin b and swinging the rod (l C to one side, be readily removed from the bottom of the cylinder for the purpose of repairing .the packing, or cleaning it, or for yany other purpose.

If' preferred, the arch YV may be cast to a ring, R, and the latter' screwed to a suitable hollow stein on the upper side oi' the diskv M, as shown in the drawing, The arch can then be detached from the disk for the purpose of inserting or removing the ball.

Having thus described my invention, `Vl/'hat I claim as new, and desire to secure by Letters 'Pat-cnt, is V A pump-plunger, constructed oi' the guide T, valve I, ring 1t, disk M, yoke-n., and standard o o', combined and arranged as herein described and for the purposes set forth.
