ROTARY PUMP.

UNITED STATES JOHN D. KELLER, OF
PATENT v GEEICE.,
SANTA CLARA, CALIFORNIA, AssIeNOR or ONE-HALF Y TO OTTO LEU, OF SAME PLAOE.
ROTARY PUM P.
SPECIFICATION forming part of Letters Patent No. 570,643, dated November 3, 1896.
Application led October 21, 1895.
To all whom it may concern:
Beit known that I, JOHN D. KELLER, a citizen of the United States, -residing at Santa Clara, county of Santa Clara, State of California, have invented an Improvement in Rotary Pumps; and I hereby declare the following to be a full, clear, and exact -description of the same.
My invention relates to that class of rotary pumps or rotary engines in which radiallyslidable pistons, revolving concentrically with the interior of the shell, are operated by an eccentrically-located cylinder or carrier, which forms an abutment at one side with the interior of the shell and a water or steam space on the other side.
My invention consists in certain improvements, some of which are applicable to rotary engines, though all are particularly and especially applicable to rotary pumps.
These improvements consist, irst, in providing an abutment past which the sand and other foreign substances in muddy or unclean water are adapted to pass; second, in a novel adjustable bearing between the pistons and the wall of the eccentrically-located cylinder or carrier` through which said pistons pass, and, third, in the novel construction by which the pivotal center bearings of the pistons are kept lubricated.
These improvements, together with their several advantages, I shall hereinafter fully describe and specifically claim, by reference to the accompanying drawings, in which- Figure 1V is a Ycross-section of my pump. Fig. 2 is a horizontal section. Fig. 3 is an enlarged cross-section Of the rocking bearing G. Fig. 4 is a vertical section of same. Fig. 5 is a view of a modification of the adjustable bearing.
A is the shell of the engine, mounted upon or formed with a suitable base. In the center of this shell is a shaft or pin C, on which are pivotally mounted the pistons D, there being one or more of these pistons, and for the sake of illustration I have here shown three. They extend in the radial planes of the shell and reach from the center to its interior peripheral surface. Mounted upon an axis eccentric to the shell is a cylinder or carrier E, adapted to rotate within said shell. This cyl- Serial No. 566,406. (No model.)
inder or carrier encircles the shaft or pin C, which forms the center of the shell, and at one side said'cylinder forms an abutment with the interior of the shell, While at either side it leaves a water or steam space. The wear 'at the abutment between the cylinder and the shell is very great and needsto be constantly taken up and compensated for. To effect this result, linsertin' the interior of the shell, at 6o the abutment, a wearing-piece H, which, being held in place by a bolt h, may, when it becomes worn and loosened, have a suitable washer placed behind it, or if necessary it may be removed entirely and another substituted. 6 5 Now, while this abutment-piece has been found by experience to answer very well with respect to an engine, I have found that in the use of the device asa pump and when working with dirty or unclean water containing 7o sand and other foreign substances it is liable to such great wear as to make it impractica ble. This is due to the sand and other foreign substancescoming over with the Water and working down between the cylinder or 7 5 carrier and the abutment-piece. To remedy this difliculty and provide for the discharge of the sand and other foreign matters without allowing it to get within the abutment, I form the abutment-piece with a back passage 8o by recessing it out, as shown at h', which said passage begins at the top with a flaring portion h2, leading out from the point Of abut ment from a sharp edge, and the bottom por- Vtion of said passage is closed in by the shell 8 5 below and has a communication through a passage h3, which may be controlled by a suitable plug Or valve h4. The sand and other foreign substances coming to the point of the abutment will not follow on down the abut- 9o ment-face, but will pass in over the sharp lip and down through the flaring portion h2 of the back passage of the abutment-piece and down through said passage, from the bottom of which it canbe drawn off through the passage h3.
This improvement I have found to entirely remedy the difficulty in the vuse of the machine as a pump. Also in its use as a pump I have found that the wear upon the bear- A10o ings of the pistons where they pass through the cylinder or carrier is very great, and in order to keep them adjusted and to compen'- sate for this wear I have the following improved construction: G represents the rocking or oscillating bearings, through which the pistons freely pass. Formed-in these bearings, radially in planes at right angles to the pistons, and on each side thereof, are sockets g, in the bottoms of which are seated plates g', within the ianged ends of which are movable wearing-plates g2, and between these wearing-plates and plates g' are springs g3, the tendency of which is to hold the wearing-plates g2 constantly against the corresponding wearing-plates in the cylinder or carrier, which I shall now describe. In the adjacent walls of the cylinder or carrier are made sockets e, in which are seated movable wearing-plates e', which are held out by springs e2. The wearing-plates e' bear against the wearing-plates g2 in the rocking bearings. The springs g3 and e2 have a tendency to keep the wearing-plates up to one another constantly, thus taking up all the wear.
As a modification of the above construction I may have the adjustable wearing-bearings shown in Fig. 5, in which the roundended wearing-plates K are seated yieldingly in sockets kin the cylinder or carrier and are held out to their bearing against the piston by means of springs 7c'. Their ends are rounded, and sufficient play being given to the piston as it passes through thecylinder or carrier said piston may have its proper rocking movement and at the same time be constantly kept in adjustment and the wear compensated for by the springprojected wearing-plates. It is also a matter of necessity to keep the pivotal bearing of the pistons well lubricated,`which necessity applies both to the use of the device as apump and as an engine. AIn order to provide for this, I provide holes c in the pin 0r shaft C on which the pistons are hinged or journaled and make said pin or shaft hollow. Its hollow interior communicates with the extension c on the outside by means of a valve c2, controlled by a spring c3. This extension c is exteriorly threaded and receives a nut c4, to which is secured a plunger c5, which operates within the hollow extension. This hollow extension is to be filled with lubricant, and as the nut is turned upon it and the plunger advanced the lubricant is driven in through the valve c2 to the interior of the pin or shaft C and thence out through its holes c to the bearings of the pistons.
The inlet and outlet passages are shown by dotted lines; and while these passages may be of my appropriate and well-known form they are herein indicated as substantially like similar passages shown, described, and claimed in my former patent, No. 550,721, dated December 3, Y1895.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-q 1. Ina rotary pump, a combination of the shell, the rotating pistons operating concentrically within said shell, the eccentricallylocated cylinder or carrier through which the pistons operate, and an abutment in said shell against the cylinder or carrier, said abutment having a downwardly-extending back passage joining the water-space within the shell and adapted to receive the sand and other foreign matters at the beginning of the abutment and to dispose of them.
2. In a rotary pump, a combination of the shell, the rotating pistons operating concentrically within said shell, the eccen'tricallylocated cylinder or carrier through which the pistons operate, and an abutment in said shell against the cylinder or carrier, said abutment having a downwardly-extending back passage joining the water-space within the shell adapted to receive the sand and other ""lltliilliii foreign matters at the beginning of the abuti ment and to dispose of them, and a dischargeway communicating with the base of said passage.
3. In a rotary pump, the combination of the shell, the pistons rotating concentrically therein, the eccentrically-located cylinder orl carrier within the shell and through which the pistons operate, and the adjustable abutment-piece within the shell having a hollow back passage communicating at the top of i therein, the eccentrically-located cylinder or carrier within the shell and through which the pistons operate, and the abutment-piece within the shell having a hollow back passage communicating and joining at the top of the abutment with the water-space by a sharp lip, whereby the sand or other foreign matter is readily delivered into the top of said passage.
5, In a rotary pump, the combination of the shell, the pistons rotating concentrically therein, the eccentrically-located cylinder or carrier within the shell and through which the pistons operate, the abutment-piece with in the shell having a hollow back passage communicating and joining at the top of the abutment with the water-space by a sharp lip, whereby the sand or other foreign matter is readily delivered into the top of said passage, and a controllable discharge-passage communicating with the base of said back passage.
