vices in which the rapid rotation of the in-v terior working partsl is 'utilized for the purpose of pumping fluids, compressing air and gases, and for producing vacuums: and consists in the peculiar construction of the parts andtheir combination which may be best and drawings The device is shown in the following-described illustrations of which Figure 1 is a longitudinal' vertical section taken through the center. Fig. 2 is a cross vertical section takenon line 2--2 of Fig. 1'. Fig. 3 is a side elevation of the pump. Fig. 4 shows in elevation a part ofthe piston-carrying drum. Fig. 5 s ows in perspective a part of the piston-carrying drum illustratinglcertain distinctive parts.
Fig. 6 shows in perspective an adjusting device. Fi 7 shows in perspective the construction fo the pistons.
My rotary pump may be used for any liquids, hot or cold, and also .for liquids that contain more or less foreign matter such as the liquids incidental to the opertions of dye-houses, bleacheries and tanning plants,
etc. It may also be used in. breweries for pumping beer in its various stages of preparation. Air and gases may be compressed or rareiied by this device.
The outer case of the pumpconsists of a short hollow cylinder, A, of metal and two side disks A1 A2. lThis case hasl an inlet B and an outlet K, a shaft C journaled in the side disk A1` and A2 is firmly keyed to the .A piston-carrying drum D D1, vsee Figs. 1 and 4 and 5.' This piston-carrying'drumconsists of a single disk- D, keyed to the shaft C, and a cylindrical ring D1. The said' piston-carrying drum is provided with radial o enings D2 D2 in which the pistonsP P are icton.
. ally held and are free to be moved in and out The outward motions the ring E as the drum rotates. of these' pistons are controlled b which is free except that the acjusting roll,
tion that it, the ring,will causeone at H,holdsit,'as shown in Fig. 1, in such a osieast reference to the specification of the pistons P P to bear against the inte riorof the case as shown. The inlet B is connected to a port-way B1 which extends to the point B2 which begins at K2, see Fig. 1. The terminations B"L and K2 of these port-ways are so near together that no pocket for the liquidA can exist that is, the port-way K1 is longer than the port-way B1Aso that the capacity of the chamber I will always be less than the capacity of the chamber I1 hence there can bel no crowding in the chambers between the pistons, which, if it existed,
"would be a great detriment to the working of the pump and .subtract largely from its efficiency.
The adjusting roll H is .mounted upon a journal H2 which is connected to the disk H1 which in turn is connected eccentrically to the 'shaft H3, see Fig. 6. By turning the shaft H3. theposition of the roll H is changed, that is, it may be advanced towards lthe portway K or withdrawn from it, thus changing the position of the piston-controlling ring E and adjusting it so that the greatest pressure of the ends of the pistons P upon the inner surface of the case shall be at the desired point between the ends of the port-ways and also the position of the chambers Pand I1, the object being to have the capacity of the chamber I1 always less than the capacityv of the chamber I, thereby preventing the possibility of crowding in the chamber I. The shaft H3 that operates the adjusting roll H extends through the side A1 of the case and and the outlet K has a port-way K1l has attached to it a lever L, see Fig. 3.. The
moving end of the lever L is operated upon bythe companion screws L1 and Lz by the turning of which the adjusting roll H may be placed. in any desired position, thus governing the piston-controlling ring E and. through it the actions of the pistons `P P.
The pistons P are constructed as shown in Fig. 7, that is, each consists of a number of plates each4 of which has an opening P1, as shown; this'op-ening is of the saine length in each of the plates of which the iston is formed, but not located longitudinally in relation to each plate the same, so that the the drum and the others from the other-l side,
as shown in Fig. 7, so that some of the 4plates will bear upon the disk A1 of the'case and the others -upon .the disk A2, thus insuring a llO in through the inlet B they Will close-fitting tight joint at both ends 'of the said istons.
en this pump is used for pumping a liquid that has IniXed With it seniiesolids, like brewers" grains and parts of hops and other material that might clog thepump, l have diagonal fillets or ribs both on the eX- terior of the piston-carrying drum andupon the interior of the cylindrical part of the case. The ribs on the drum are indicated by D3, Fig. '5, and those on the interior of the case by A3, Fig. '2. These ribs will crush and grind up the clogging material and thus prevent it .from interfering with the action of the pump. y
To avoid theeil'ect of small solid particles that by chance get into the pump and catch between the pistons and the case, l. cut away apart of the piston-carrying drum as shown at R, Fig. 1, and l cut into the case as shown at l, so that if any solid articles get Y e caught in one of the recesses Rand be carried to the outlet K, and as the pistons are forced inward the-solidswill 'be likely to fall 0E and be ejectedthrough the outlet; even if the solids be carried to the recess T, Fig. l7 then they Will be pushed od and dropped. For convenience 1n oiling I have oil ducts and and for the purpose holders N and N1, see Fi 2. From the duct N leaders N2 and' N3 ta e the oil to the interior; Claims. v .Y
