PUMP.

SPECIFICATION forming part of Letters Patent No. 349,951, dated September 28, 182m.

Application tiled January .'20, 1336. Serial No. llllls. (No model.)

To all whom it may concern:

Be it known that we, THoM'As PATTEN, Jr., and (JHRis'rL-tu ANDERsoN, citizens ot' the United States, residing at Appleton, in the county of Outagamie and State ot' Wisconsin, have invented a new and useful Improvement in Pumps, of which the following is a specilication.

Our invention relates to that class oi' pumps which are designed l'or use in paper-mills for pumping the liquid pulp from one receptacle to another, and are termed stuff-pumps,7 but may be advantagcously used for a variety of purposes.

The object of our improvement is to produce a greater and more even iow of the liquid or st-uff, and thereby produce paper of even thickness and uniform weight throughout the entire "'batch7 or quantity desi red; also, to produce a pump that is durable in use, its wear being uniform in the valve and seat, whereby it is kept tight and t'rce l'rom leakage; and', furthermore, ol' such construction as will permit access to its parts t'or the purpose ol' removing obstructions and l'or making the needed repairs. \Ve attain these objects in the manner shown in the accompanying drawings, in whichq Figure l is a vertical elevation, partly in section, of the pump upon the line a: ./1: of Fig. 3. Fig. 2 is a vertical elevation ofthe pumpcylinder and valve-chambers; and Fig. S is a top view upon the line ol' Fig. 2, showing the valve d in its chamber, the valve-guides c, the handhole plate h., and the clamp lby which it is seemed in its position.

Similar letters refer to similar parts in the several views.

A is a post of wood, to which the pump is secured by bolts. B is the pump-cylinder. C is its piston.

D D are the valvechambers. el d are globevalves. E is the piston-rod, and F the conneetion-rod, by which the piston is given a reciprocating motion by a crank or other-suitable device.

a a are feet cast with the pump, by which it is secured to the post A with bolts, as shown.

In the upper end of the cylinder B is a gland, l), for the retention of packing around the piston, in the usual manner.

\Vithin the valve chambers are guides c and c', b v which the valves l and l/ are guided in their vertical movement, and made to fall squarely into their seat and make an immediate and perl'ectjoint. These guides c and c' are cast with the valve-chambers, ample room being left between said guides l'or the i'ree passage of both the valves and the liquid it is desired to elevate.

c is the suctioupipe, and f the dischargepipe.

h l1. are handhole plates, which are secured in place upon the valve-chambers by the clamp and bolts l. f/, the removal ot' the plates giving access te the valve and its chamber for repairs thereto, and for the removal ol' obstructions which may lind lodgmcnt therein.

The cylinder l2, valve-chamber D', supply and discharge pipes, &c., are l'ormed in separate pieces, and screwed or bolted together, both t'or their easy construction and repairs.

Its operation is not unlike that ol' pumps which have been long in use. .lhe raising of the piston exhausts the ai r from the chamber, the valve dis raised, and the pulp or liquid enters. Upon the return of the piston the valve l is closed, the valve d opened, and the liquid forced up and delivered through the pipef to the place required. The valve-chambers are located in close proximity one to the other, unlike those formerly used for this purpose in paper-mills, whereby the smallest amount of liquid is accumulated under the valve d', and subjected to the suction of the piston on its upward stroke, thereby producing the smallest variation in the amount ol' liquid elevated at the several rcciprocations of the piston.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

l. In a force-pump, the combination of the cylinder B, the valve-chambers D and B', the plunger or piston C, the globe-valvesd and d', their seats, and the .valve-guides c and c', the latter formed integral with the chambers l) and D, respectively, substantially as shown and described.

2. In a force-pump, the combination of a IOC cylinder, a plunger or piston adapted to be access to said valve-chambers, substantiallyas reciprocated therein, two valve-chambers-in seb forth.

close-proximiby one to the other, having each THOMAS PATTEN, JR.
