PUMP.
Specification ot 'Be it known that we, HENRY CLAY LYoNs, CHAnLEsRoMAINE CLARK, and WILLIAM T. MGLEN, citizens of the United States, residin at Alexandria, in the county of' l Alex1 yaiidria and State of Virginia, have invented certain new and useful lfmprovementsjin Pumps; and we do declare the lfollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings, and-to the letters and figures of reference marked thereon,'.- which form apart of this s eciic'ation.
Our invention relates to torce pumps but more particularly to that 'class ofrotary pumps in which an eccentric-'movement of the pistons is 4employed for forcing air, water or other liquid frointhe pump. Our inventionhas for its object to provide a device of this class which is so constructed and arranged that a great volume of air, water or other liquid can be forced by the pump with a very slight eccentric movement of thepistonsl Y. further object of our invention isto provide a pump of large capacity and of a comparatively small size.

A' further object of our invention is-to provide means lfor preventing the pounding vof ahe piston' rings against 'the dividing A further object of our invention iB ti) provide a more desirable and convenient l1ocation of theintake and discharge ports.
'With all theseobjects in view our invention consists in the 'arrangement of the shaft and the adjustable eccentric bushing and pistons whichpreve'nts the access of Water to the 'shaft and adjustable eccentric bushing.
Our invention further consists in acon- -struction-which provides for leading a portion of the discharge' ateror fluid behind the same in its proper relative position.

5 of said pistons isv that the wall or plate threaded` to receive a capl 14.
Referring to the rear wall or plate 6 of the pump it will loe-seen that the same is centrally 15 threaded to receive a cap 15,-said cap being of such a size as to permit removal of the 'cap 14 in order to rotate the eccentric bushing 11 on the eccentric enlargement 10 loi? the shaft 9 in order to adjust the eccentric 2o pistons. 1t will also be seen from Fig. 4
that the rear'plate or wall 6 is provided with la vertical groove 16 (also shown in Fig. 6),
while the wall or plate 5 of the eccentric' pistons 4 is provided with-a pin or extension '17 which enters the said groove 16. Referring to Fig. 3 it -will be seen that the,
shell 7 of the pump is cored at 18 and 19, the
While the core 19 communicates with similar p ports 22. and 23.
Referring now to Fig. lit will be seen that the stationary pistons 2 connect with one another by means of two cored passages 24 and 25, said cored passages being clearly shown-in F ig. 2, a central web 29 being employed to divide the cored passages 24 tnd 25. It will be seen from Fig. 5 that the cored passage 24 communicates with the space between the stationary gistons 2 by means of suitable ports 27, while a port 28 connects the cored passages 24 and 25 with the cored 18 in the shell of the pump; this being clearly shown in Figs. 3 and 5.
29 indicates a dividing wall arranged as shown 1n F lgs. 1 and 3, while the eccentric pistons 4 are each .provided with a slot 30 in order to allow said pistons to straddle the dividing wall or partition 29 as shown in Fig. .3. -Reierring now to Figs. 5 and 6 it will be seen that a threaded port 40 connectsE the l cored passage 18 with a cored passage 41 in the rear plate or casing 6 of the ,pump (Fig. 6). It will also be observed from Fig.l 6 that a similar cored passage 42 is provided, which by means ot a threaded port 40 50 2) connects the cored passage 19 (Figs. 2v
and 3) with the cored passage 42, the vport 40 and cored passage 41 being to one side of the center of the pump while the port 40 and cored passage 42`are to the other side of the center of the pump.
From 5 it will be seen that the cored passage 42 communicates with the space in as the intake the ports 20 and 2 3 are plugged as lshown allowing the Water to discharge through port 22. When running the pump in the reverse -direction the ports 21 and 22 are .plu ged, the ports-23 and 20 becoming the inta re and discharge ports. Consider'- ing, however, the port 21 as being the intake, the water or fluid enters said port and passes into the lower portion of the cored passage 18 (Fig. 5) from the cored pa ige 18 it passes through the port 28 ir' the cored passage 24 along the front all orv casing 3 of the stationary pistons 2 entering between the pistons through the ports 27 By means of the eccentricy action of the pistons 4 the water or liuid is forced from the dividing wall or partitt ,in 29- around the pistons to the opp'osite eine 'of the dividing wall or partition 29 where it is discharged through the portsl 27 ,nto the cored passage 25 (Fig. 2), then tl.rough the port 28 into the cored passage 19 (Figs. 2 and 3) being forced up said fired passage 19 discharging through the port 22.
Referring now to Fig. 5 it will be seen that the port 40 entering t-..e cored passage 19 allows a portion of the discharge water to, pass throughsa'id'port 40 into the coring 41 in the rear plate `6 of the pump; from the coring 41y it passes upwardly between the rear plate 6 and theplate or wall 5 of the movable pistons 4; thus the pressure of the discharge acts upon the plate or wall 5of the eccentric pistons 4 to hold Vsaid pistons in their properrelative position, thus insuring a tight 'and etlicient pump. lhen the wateris ,being forced -into the passage 42,
the port 40 leading to the passage 41 is plugged as shown in Fig. 2, and when'the passage 41 is receiving water, the port 40 leading to passage 42 is plugged.
1t has been found that the eccentric movelment of the movable pistons causesthem to strike violently againstthe dividing wall or partition 29, thereby creating considerable noise. In order t'c obviate this diiliculty and render the pump noiseless we providev the' groove 16 (Figs. 4 and 6) within which is a guide pin or extension 17 on the plate or wall 6 of the eccentric pistons This guide pin being directly in rear of the dividing 'wall or partition 29 allows the pistons a free vertical -movement at this point and prevents any lateral movement su'fiicient to allow the pistons to engage the vertical wall or "pari titicn 29..
35 with, a shell or casing for-said pistons, said obviously depending upon the character of ing Water having considerable sand and grit passages, each. cored passage partially smirounding'the said pistons; a partition Aat 4opposite points of said shell or casing for Should it be desired to alter or adjust. 'Y the eccentric pistons the same is accom-t plished by removing the cap 15 from -the rear'v plate or Wall (5 of the pump (Fig. 4,-)` then` removing the cap 15 in the plate or Wall 5 of the eccentric pistons l. By means of a suitable Wrench the bolt or screw 13 is loosened allowing the rotatable bushing 11 t'o be rotated on the eccentric enlargement 10 of the shaft 9. 'Y By this construction a very neat and fine adjustment ot' the pistons can be effected, the extent of adjustment.
the Work to which the pump is to be subjected.
It Will be seen from Fig. 4 that the eccentric bushing 11 being. provided with a Wall 12 and the plate or wall 5 ofthe eccentric pistons 4being provided with the cap 14 all water or.. fluid is excluded from the` shaft and eccentric bushing. As pumps of this character are frequently employed for pump-- therein itis at once apparent that the life of the pump, and partlcularlythe shaft and bushing, 's very materially lengthened by excluding the'tvater laden with sand or grit from these rotating parts.
, Having thus fully described our invent-ion what We claim as new and desire to secure by Letters Patent of the United States is,-
'1. A pump of the character described,l comprising one or-mor'e stationary pistons and one or more movable pistons associated thereshell or casing being'provided with two cored separating the said two cored passages, each cored passage terminating in an intake port at one end and a discharge vport at the other, al `port communicating vwith each of said cored passages .for lea ing the Water to and from said pistons, the Whole arranged inv such manner that' the discharge from the pistons passes ato one o said cored passages and is led partially around said pistons be tore being dischar ed from the shell or ca sing, substantially' s described.
