ROTARY PUMP.

Specification of Letters Patent.

Patented Feb. 16, 1915..

Application filed .Tune 28, 1913. Serial No. 776,341.

T0 all whom t may concern:

Be it known that l, VICTOR G. MUNsoN, a citizen of the United States, residing at Whitehall, in the county of Muskegon and State of Michigan, have invented certain newv and useful Improvements in Rotary Pumps, of which the following is a specification.

This invention relates to fluid transmitting pumps of the rotary type, and has for an object the provision of a rotary pump for efliciently pumping water and like liquids.

Another object lof this invention is the provision of an improved valve mechanism which is automatically operated by the 'operation of a pump plunger and which prevents any fluid which is drawn in the pump casing from receding into the inlet of the pump.

A still further object of this invention is the provision of a pump plunger which is provided with means for automatically taking up any wear caused by the continuous operation or rotation of the plunger.

`With the foregoing and other objects in view, this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the ac companying drawings and claimed.

ln describing the invention in detail reference will be had to the accompanying drawings wherein like characters of refer ence designate like or corresponding parts throughout the several views, and in which,

Figure 1 is a vertical sectional view through the improved pump; Fig. 2 is a side elevation of the pump showing one side of the outer casing removed; Fig. 8 is a cross sectional view through the pump; Figs. fl and 5 are detailed side elevations of parts of the pump; Fig. 6 is a detailed perspective view of the pump plunger; and Fig. 7 is a detailed perspective view of the improved valve for preventing the backward action of the water which is drawn into the pump casing.

Referring more particularly to the drawings, the numeral 1 designates one side of the outer casing of the pump and has a Hangs 2 formed integrally therewith and extending inwardly from the inner surface of the side 1. The side 1 of the casing of the pump is circular in shape as is clearly shown in Figs. 1 and 2 of the drawings.

The side 1 has a bearing 3 formed thereupon in which is rotatably mounted a shaft 1l. The shaft l has a shoulder 5 formed thereupon and the reduced portion 6 of the shaft which extends beyond the shoulder 5 has external screw threads formed thereupon adjacent the shoulder 5. The external screw threads formed upon the reduced portion of the shaft l are engaged by a nut 7 which is seated in a recess 8 centrally located in the washer 9 which is constructed of leather or other suitable material. The washer 9 is held in place and against the edge of the liange 2 by means of a plate 10 which is secured on the flange 2 by means of bolts 11 which are inserted in screw threaded apertures 12 formed in the flange 2.

The shaft 6 has connected to its outer end any suitable means not shown) for transmitting power thereto such as a crank handle, pulley or the like.

A. plate 15 is mounted upon the reduced portion 6 of the shaft ll, abutting the shoulder 5, and rotates in unison with the shaft This plate 15 is provided with a out out portion 16, formed therein, which receives the main body portion 17 of the pump plunger 18. The plunger 18 has a reduced portion 19 formed integrally therewith and eX- tending outwardly from one end thereof. The reduced portion 19 gradually tapers inwardly as it extends away from the body portion 17'of the plunger 18 and terminates in a point 20. The reduced portion 19 has a roller 21 rotatably'mounted .upon its upper surface, the purpose of which will be hereinafter more fully described.

Seated within a recess 22 formed in the body portion 17 of the plunger 18 is a plate 23 which has an expanding coil spring 24, which is seated within a recess 25 formed in the plunger 18 abutting its inner surface and pressing the plate 23 outwardly so as to engage the inner surface of the flange 2 during the operation of theplunger 18. This plate 23 serves a Vpurpose identical with the piston rings of an engine in that it absorbs the wear occasioned by the continuous operation of the plunger 18.

By seating the body portion 17 of the plunger 18 within the recess 16 formed in the plate 15, the plunger will be caused to rotate synchronously with the plate 15 and as the plate 15 is rigidly connected to the shaft 4, the former will rotate when rotary motion is imparted to the `shaft4 by the means heretofore set forth. In this manner the operation of the plunger 18 maybe started.

The fiange 2 has two

openings

30 and 31 formed therein each of which receives a screw threaded portion of the

pipes

32 and 33 respectively. The pipe 32, which is seated in the opening 30 has a second pipe 34 connected thereto in any suitable manner. The pipe 34 has its endy 35, which is connected to thepipe 32, enlarged and a. ball 36 isl` seated therein.

rlfhe pipes

34 and 32 andthe opening 30 form an inlet for the interiorof the casing of the pump and the pipe 34 is connected4 to any suitable source offwater 'or' other liquid supply. 'The ball 3'6vi's of greater diameter than the interior ofthe pipe 32 andthe latter has its end 37 which is seated within the enlarged portion offthefpipe 34, shaped so as to form a seat for the ball `36 and prevent the same from passing intothe interior of the casing. The end 37v ofy they pipe 32 is also shaped so as to 'allow water or other fluid to pass therefrom' and into the interior of the casing of the pump when the ball 36 is in engagement therewith.

' The opening 31, and the pipe 3,3 form an outletffor 'the fluid which is drawn into the interior of the casingpof the pump' through the'inlet opening. y

"A 'circular'shaped member 38 is mounted within the pump.casing and is securely and rigidly connectedl to the side by means of bolts 39, f The shaft 4 is rotatably mountedin an opening 4Qwhich extends-through the member i3.8.

The member 38 has a cut out portion 41 formedin its lower side which receives the tongue 424 of the valve member 43. The tongue 42 is pivotally connected to the member 38 by means of a pin 44. The lower end 45'jofzth'e valve'member 43 is shaped so as to fit snugly yagainst the inner surface of the flange 2 and vform a fluidtight joint therewith," The outer lower vedge 46 of the tongue 421is shaped so as to conform to the shape of thev upper edge 47 of :the reduced portion 1,9,oif vthe :plunger 18 and 4,is engaged b'yjj'the roller .21, during a predetermined periodinthe operation `of the plunger 18. llh'en the roller 21 engages the surface 46 ofthe 4tongue' 42 it forces the same up-k wardly` Awithin the recess' 41Vformed in the member 38.and` forces the valve member 43 upwardly a recess 48which is formedl within the member 38 and .against the ten-v sion of y,a eoil spring 49` which is mounted within the recess 48.

A recess 50` communicates with a recess48 and thas a coil spring 51 mounted therein.

The coil springs 49 and 51 force the valve member 43 outwardly out of the recess 48 and into its normal position as is shown in Fig. 1 of the drawings, after the plunger 18 has passed beyond the outer edge of the opening 48 during its stroke. A small opening 52 communicates with the upper and inner end of the recess 50 and extends entirely through the member 38 forming an outlet for any air, water or the like which might be contained withinV the recesses 49 and 50.

The valve member 43 forms means for preventing the water or other fluid which is drawn into the interior of the pump casing from receding into the pipe 32 and causes the entire amount of fluid drawn into the casing, upon each stroke of the piston 18, to be forced outwardly through the pipe 33.

A peripheral chamber is formed in the casing of the pump about the outer surface of the member 38 and the plunger 18 operates within this chamber.

The suction generated by the operation of the plunger 18 within the peripheral chamber formed in the casing draws water or other liquid into the peripheral chamber through the inlet and as the plunger 18 lits snugly within the peripheral chamber within the interior of the casing and about the outer edge of the member 38 the iiuid is d forced outwardly through the pipe 33 by the shoulder 54 of the body portion 17 of the plunger 18.

In practical fields certain minor features of construction, combination and arrangement of parts may necessitate alterations to which the patentee is entitled provided such alterations are comprehended within the scope of what is claimed.
