l UNITED i STATES PATENT Orricn. y
RANDOLPH S. FOSTER, OFNEW YORK, N. Y.
IMPROVEMENT IN ROTARY PUMPS.
I Specilication forming part of Letters Patent No. 4 5,596, dated December 27, 1864.
.To aZZ whom it may con-cern:
Beit known that l; RANDOLPH S. Fosrnn,
" ot 191 WestEighteenth street, inthe city,
county, and State of New York, hav invented a new and Improvedlotary Pump; and I do hereby declare that the following is a full,
clear, and exact description thereof, lwhich `will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawings, in which- Figure 1 is a side view of my invention, the
side ofthe case nearest the eye being removed in order to show the working parts; Fig. 2, a section ofthe same, taken in theline ma, 'Fig-1 l; Fig. 3, a section of'a portion of the same, taken in the line y y, Fig: 2. a
Similar letters of reference indicate like Vcast meta-l and of any suitable dimensions.
This cylinder has a pipe", B, at its upper part; and G is a pipe which communicates with the cylinder A at one side'of it. The cylinder DA is of such diameter that its periphery-will4 workin contact with the inner side ofthe 'periphery of the cylinder A', (See Fig. 1,) the cylinder D being equal in width to'the 'interior 'of cylinder A, as show-n ineFig. 2.
The cylinder D has ,a circular--groove,'ol,l made in it all around -nea-r its periphery, and
. in this groove a pin,b, on a bar, E, is iitted, lthe latter being permanently attached to oneside of a plate, F, which is iittcd ina case, G,
' secured tothe exteriorof the cylinder A, and
in radial position the ewith, as shown in Fig. 1. Wthiu the'case'', and below the plate F, there is iitt'ed afplate, H, in the lower end of which there isa recess c, to receive packing I, of leather orothergcsuitable material,an this packing is kepti contact with the rperiphery of the eccentric cylinder D by means ot' aspring, J, which is 4secured "to the upper end'of the plate ..H and tears againstthe upperY edge ot a recess, d, in the plateF.
Thisspring J may be otf'- semi-elliptic for' other proper form. The upper part Vof the Y plate H is diminished in thickness to form what may be -term ed a t tenen, c, which istitted and works in the recess `Yr11, as shown clearly in Fig. 2.
By referring to Fig. .l itwill be seen that l the plates FH are between the pipes B O, and
form an abutment or cut-oft' between them when the cylinder Dis not incontact with the inner periphery ot' the case A between the) two pipes. A A 4.
,The eccentric cylinder D and plates F H divide the cylinder A intotwo compartments,
ef, the suction-pipe O communicating with e, and the pipe B, which is the eduction o r dis charge pipe, communicating with the compartmen'tf. (See`Fig.`l.)
The cylinder D is rotated in the direction indicated by the arrowle-and..the;.,.ccinpart: ment etills with water through pipe 0, a suc-- tion being produced in e by cylinder D, aidat the Vsame time the water ncoinpartmentf is'iorccd out through the pipe B. When the periphery of the cylinder D touches the inner periphery of the cylinder 4A at a point between the pipes B C, the two chambers e f may be said to be united, and both are illed with water, but the orifice of the pipe C is,"
closed by the cylinder D, so as to prevent any reaction or downward pressure of the water in O, the latter beingcut olf byD just previous .to theunitiug of the .tw'o chambers.
The plates F H work in and out offtlie-cae 'Gr-.Tas .the cylinder D maten-tte packing 1 and spring J, insuring a'water-tiglit contact between the platel H and the cylinder D 'at all points in the pathot rotation of the latter. l would remark that the edu-ctionor force pipe B may, instead ot' communicating directly with the case A, be connected'with-an air-vessel, the latter'being placed on the exterior of the case A and over the case- G. This invention forms a very'etlicient andA simple r'otary pump, one which will not be affected by wear, and it may at the same time '.be1eonstrueted ata very moderate expense.
I claim as new and desire to secure' by Let-f gtersPatentu 1;*The eccentric cylinder D, placed within the cylinder A and in relation'with the pipes B C, as shown, in connection with the sliding abutment or cut-ott' working in acase, G, ccnloathe purpose set; forth.
