Application filed September 1, 1883. (No model.)

Be it know'n that .1, JOHN M; sum of l Butte Qity, county of Oolu'sa, and State of Oalifornia, have in ventedan Improvementin Ho tary Pumps; and Thereby declarethe following tobea full, clear, and exact description thereof.

Myinvention'u'elates to certain improvenents in rotary pumps; and it consists of an exterior case with inlet and discharge passagesfanflintcriorcylindrical drum revolving upon anlaXis,-which-is placed. eccentric to the outercaseand slotted to receive buckets, and aloose elastic ring which isplaced within the drum and the inner edges of the buckets, against which it presses and holdsthem out to the inner faceof the case. c l

c It also consists of certain details of construction, whichwill be more fully explained by reference to the accompanying drawings, in

wvhich- Figure 1 is a vertical section of the pump,

taken transverse to the shaft. Fig. 2is a vertical section in a plane through the axis of the shaft.. Fig. 3 is a section of the drum. Fig.

. 4 is an elevation of the drum. Fig. 5 is a perspective View of the drum. Fig. 6 is a View of one of the buckets. Fig. 7 is a horizontal section of the pump, the upper portion of the drum being broken away. i

A is the'outer case, which is in the form of a cylinder, and has an inlet-passage, B, and an outlet, G. A shaft, D, passes through the ends of the case, but at one side of the center, and it has a cylindrical drum, E, keyed to it, so

i as to be revolved by power applied to the shaft exterior to the case. This drum has radial slots F, extending from its periphery toward the'center, into which the buckets G are fitted to slide. A loose elastic ring, H, is dropped into the drum E from one end, and the, inner edges of the buckets have notches I, which fit over the ring and keep it in a central position.

.When all the parts are in place, one side of the drum comes in close contact with the in terior of the case just below theoutlet-passage, while from the position of the drum within the case there will be a crescent-shaped space upon the opposite side. The outer edges ofthe buckets are kept in contact with the inner circunr ference of the case by the pressure of the clastic ring H against their inner edges, as shown.

The inlet-passage is at the bottom of the case, i

and when the drum is revolved the buckets are carried around, andby reason of the shape of thespace between the drum and interior of the case, water or other liquid or fluid is drawn into the case through the inlet-passage,and is carried around and forced out through the outlet. The buckets are forced out to the full distance between the drum and the case by the pressure of the interior elastic ring, and they are prevented from catching,when they pass the inlet or discharge openings, by bridges J, which crossthese openings, asshown. .If any thing obstructs the movement of the buckets, the elastic ring allows' them to be forced back in the radial slots without interfering with their forward movement, and as soon. as the obstruction is passed the ring forces them out again to the inside of the drum.

Having thus described my invention, what I S. H. N oURsE, HENRY 0. LEE.
