ROTARY PUMP.
Specification of Letters Patent.
Patented July 14, 1908.
Application filed August 1, 1906. Serial No. 328,782.
To all whom it may concern:
Be it known that I, LEE DANIELS, a citizen of the United States, residing at Placerville, in the county of Eldorado and State of California, have invented new and useful Improvements inqtotary Pumps, of which the following is a specification.
My invention relates to rotary pumps of the type including an eccentrically mounted piston and an independently movable gate.
' The primary object of my invention-is to provide means whereby the piston may be readily and quickly adjusted to compensate for any wear thereof.
With the above and other objects in view,
the invention consists of the construction,
combination and arrangement of parts hereinafter fully described, claimed and illustrated in the accompanying drawings, where- 1n:
Figure 1 is a vertical transverse section of a pump constructed in accordance with my lnvention. Fig. 2 is a vertical longitudinal section thereof. Fig. 3 is a sectional view taken longitudinally through the cylinder on the planelndicated by the line 3-3 of Fig. 1, the cynnder, heads, piston and gate being omitted. Fig. 4 Iis an end view of the piston. Fig. 5 1s a sectlonal view taken longitudinally througlrthe piston on the plane indicated by thehne 5-5 of Fig.4. Fig. 6 is a detail perspective view of the gate, the packmg blades belng omitted. Fig. 7 is a detail view in front elevation of the stuffing box,
the capnut, gland and packing being omitted. Fig. 8 1s a vertical central section therethrough; Fig. 9 is a detail view in rear elevation of the thrust bearing, the stem being removed, and Fig. 10 is'a vertical cen- "with longitu tral section therethrough.
Referring to the drawings by reference numerals, 2 designates an open ended cylinder, and 3-4 the heads thereof, The cylinder 2 is formed withvertical flan es 5, and the heads 3-4 are formed with io'rizontal flanges 6 which are ada ted to engage oyer' theflanges 5 when the eads are in applied posltlon. Theheads are secured in position y bolts 7 and nuts 8, the bolts bein passed through the flanges 5 and the bee The cyllnder 2 is provided with an'intake port 9 and a dischar e port 10 which communicate 'nally extending recesses 11 formed in the inner wall of the cylinder,
which inner wall is also formed with recesses 12. The recesses 12 extend from one side wall of each recess 11 andgradually diminish into the inner wall of. the cylinder 2. The cylinder 2 is formed with coupling bosses 13-14 inclosing respectively the ports 9-10 and havin respectively connected therewith a disc arge pipe 15 and a' supply pipe 16. A longitudinally extending flange 17 is formed upon the under side and exteriorly of the cylinder 2, and provides means by which the pump may be secured to a suitable base or suppor-t. 1 The flange 17 isstrengthened and braced by a web 18 formed upon the under side of the cylinder and extending from the coupling boss 14 to the flange.
The heads 3-4 are provided with longitudinally alined and eccentrically arranged openings 19, and with a plurality of screwt readed openings 20 arranged in lanes conthe openings 19. At rust bearing 21 is formed at a point intermediate it's ends with an annular ange 22, the location of the flange providing a boss .23 which is ada ted to be received by the opening 19 in the ead 4. The flange 22 is provided with a number of segmental openings 24 which are arranged in a concentric plane, and through the medium of which the thrust bearing is adjustably secured in applied position by bolts 25 assed through the opening 24 and threaded y engaged with the openings 20 in the head 4. The bearing 0 ening 26 of the thrust bearing is eccentrical y arranged with relation to the lane in which the openings 24 are located. A stuffing box 27 is formed at a centric wit flange 28, the location of said flange providing a boss 29 adapted to be received by the opening 19 in the head 3. The flan e 28 1s provided with a number of segmenta openmgs 30 which are arranged in a concentrlc rim is adjustably secured in a y bolts 31 passed through t and threadedly engaged with The bearing spectively. A suita le packing 34 and a shaft 33 is J s 26 and 32 in depth and merge attheir opposite ends point intermediate its ends with an annular plane, an? through the medium of which the 4 I of the stufling box is eccentricalliy;
27, and a cap-nut 36 has men erewith.
A ton 37 is fixed upon the shaft 32, and
it consists of two approximately semi-cylin- 1ch are secured to a hub drical sections 38 w 39 by spokes 40 in a manner to provide two 7' blades being yieldingly hel 'cur in the openin 0 I In view of the act that the piston 37 is ec diametrically opposed and longitudinally ex- I tending openings 41, said openings beingprovided to adapt the iston for the reception of a radially movab e gate 42. The gate 42 com rises two sections 43, recessed as at 44, for t e reception of the spokes 40. The outer edges of the sections 42 are provided with longitudinally extending recesses 45 adapted blades 46, said in enga ement with the. mnerjwall of the cylinder 2 t ough the medium of springs 17 located within the recesses 45 behind the packing blades,
In order to limit the thrust of the shaft, an
for the reception of packing adjustable stop 48 is provided, which is car ried by a screw-threa ed stem 49, said stem being adjustabl mounted in a screw-threaded opening in t e extension 50 of the thrust bearing 21 and projected .exteriorly thereprovided: with an angular head 51 which the'stein may be adjusted. By means of the adj ustability of'the stem, the stop carried'thereby' may be inwardly or outwardly moved to limit the longitudinal thrust of the shaft and to take u anylwe'ar' that may 0cthe bearing.
,centricalliy mounted withinlthe cylinder 2, a portion 0 the piston is at all times in contact with a p'ortio'n ot the inner wall of the cylinder.
i v connection witht In order to take up anywea'r that mayoccur to, either the inner wall of the cylinder orthe piston, theshaft 33 maybe'adjusted through the 'medlum of the thrust bearing 2 1 and the stuffing box '27, this adjustment being permitted. .through. the, medium of the segmental open-' ings 24 and 30 located respectivelyin'the flanges of the'thrust bearing and stuffing box.
