IMPROVEMENT IN ROTARY PUMPS.

Specification forming part of Letters Patent No. 55,318, dated June 5, 1866.

To all whom it may concern Beit known that I, HENRY MAAS, of Homestead, Iowa county, State of Iowa, have in` vented new and useful Improvements in Rotary Pumps 5 and I do hereby declare that the followingis a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had to the accompanyillg drawings, forming part of this specication, in which- Figure lis aside elevation of the pumpeasing; Fig. 2, a plan or top view of the lower section ot' the pump-casing, witl1 the upper section and revolving disk or plate-ring ot' the same removed; Fig. 3, a central vertical section taken in the plane of the line c x, Fig. 2, with all the working parts of the pump and the two sections of its casing placed properly together and fastened; Fig. et, a view of the under side of the revolving disk or plate-ring, and Fig. 5 a plan view of the interior of the upper casing with all the operating parts removed. f

Similar letters of reference indicate like parts.

Ain the drawings represents a hollow round casing divided into two equal parts or sections,

. B B, secured together by screws or in any other ner, and are at equal distances apart, with an opening, I, between every t\voot` them, which openings are all similar in shape and each bounded by that portion of the inner side of the ring Gand the periphery of hub H included between the edges ot' every two of the arms F. Each of the arms F, both upon their upper and lower sides, have a shoulder, J, extending in the direction of their length, and in a radial line with the center of the ring (J. The hub H projects above the upper edge of the rin g G. but is in the same line with its lower edge, Each of the openings I of the ring G, formed as above explained, is closed by a plate, J, corresponding in shape thereto, resting upon the shoulder portion ot' the upper side ot'one of the arlns F and tting the shoulder of the' under side of the next arm thereto, either toward the right or left, as the case may be, which plates are ot the same thickness as the arms, and are each hung so as to balance, by trunnion-pins, a, one upon their outer circularshaped edge, fitting the inner side ot' the ring G, and the other upon their edge fitting the periphery ot' the hub, but in aradial line with each other from the common center of the hub and ring, turning respectivelyin suitable bearings of the ring and its hub at the proper points therefor. The inner trunnion-'pin of each plate, J, has a similar quadrant-shaped arm, K, which arms, when the plates are horizontal or resting upon the shoulder portions of .the upper side of the ring-arms F, project down,- ward in a plane at right angles thereto, their curved edges corresponding in shape to the stationary annular cup-shaped cavity L of the central portion of the lower casing-section.

M is a vertical shaft passing loosely through the upper section of the casing A and the center of the ring-hub H, with diametrical notches c of which it isinterlooked by its diametrical pins d, turning at its lower end in a suitableshaped socket or bearing, N, in the lower section of the casing A. By turning this shaft either to the right or left it necessarily turns with it the ring and hub, with the series of plates balanced between them, as explained, each ot' which, as the quadrant-shaped arms -of their inner trunnion-pins, upon which they are hung, abuts in turn against the stop O,formed in the annular cup-shaped cavity K of the lower casing-section, are swung upwardV from their seat upon the ring and hub arms and brought-into a vertical position, ora plane at right, angles thereto, the quadrant trunnionarms of such plates then lying in the annularshaped recess I?, surrounding the shaft M, in the under side of the hub, from which position, by continuing the rotation of said shaft, they (the -said plates) are swung down again into a horizontal position upon or in the same line with their ring-arms, from which they were raised or swung up, as explained, by their abutment, in turn, against the corner Q and inclined edge R of the block or stop S at one portion of the annular-shaped channel or way T of the upper j casingsection; the transverse section of which,

in connection with the annular channel or way U of the lower section, corresponds exactly to the periphery or edge of the rin g-plates or win gs as they move around in the same. In this horilhui'g, as described, theiifaterpthus admitted will be carried around with the plates and by l y th ein discharged from the pulnpcasin g through suitableontletor escape therefor leading zontal or flat positionl they renraiii aslthtey in; turn pass between the lower face of the said block ofthe upper casing-section and ablock, T, in a position and of a length corresponding thereto, or nearly so, of the lowersection, the

space between these two blocks beingequal to' the entire thickness ofthe plates when the quadrant-arms of the plate trunnion-pins in turn againA abutting against the stop'of the cup- Shaped cavity of the lower section, the plates ar'e again' in turn swungupintoa vertical poi-1 sition, and again movedbackinto a horizontal position as they strike' the'corner Q and-inclined edge R ofl the upper section" of the casing=block S; when; as each, in turn, passingy between vsuch blocks- SV and the block 'correr spending! thereto in" the lower section,- it is again swung' in avertical or right-angula-r.por`

From the' above-F description of the manner in which the several plates: hung to therevolvigring or disk C et thepumpcas'ing are operated ilr connection with the internal con#4 struction of the latter and the general arrangef ment of the whole together,` it ijs plain to bel s'cen that if the pump heplaced in the bottom j of the well, for' instance; with a suitable opening incide in itsic'asin'gtoallow`l water to enter it at such part or portion of the same as the plates are swung into a vertical position, or, in

other words, at right angles to the plane of u rotation of the common ring in which they are up through the well, arranged at such point of i the pump-casing as the plates are swung back into line, or so as to coincide with the plane of rotation of their common rin g, thereby causing the water to be forced up from and out of the well,` as is obviouswi-thout'ainy further explanation it bein g here advisablefhowever, to state, inl c onclu'sion,` thatit' is necessary that all the working and-slidifgparts of the pump 'should be watertight so far as possible and practicable;
