ROTARY PUMP.

Specification of Letters Patent.

' Patented. June 9, 1908.

Application filed July 12, 1906. Serial No. 325,80

To all whom it may concern:

Be it known that we, MAURICE MOORE and J OHN MURRAY, subjects of the King of Great Britain and Ireland, and residents of 178 Bellair street, Kensington, in the city of Melbourne, in the county of Bourke, and 118 U per H0 e street,'in the town of Geelong est, in t e county of-Grant, respectively, both in the State of Victoria and Commonwealth of- Australia, have invented certain new and useful Improvements in Rotary Pumps, of which the following is a specification. I

The object of our invention is to provide a mechanism for pumping air, gas, water or liquids or semi liquids of any character. In the past a variety of devices have been used to t and simple pump is produced havin but few wearing parts and absorbing but little ower. Referring to the drawings which orm a part of this specification Figure 1 is an elevation partly in section of our pump. The

cover an the casing and the pumping disk occupy the is a view of the discharge end of our casing andpum ing disk. The bracket discharge the ring are removed and both same relative position t at they do in Fig. 1. Portion of the pumping disk is broken away to show the passa e-ways from the ports to the tubular spind es. Fig. 3 is an interior view of part of the casing, andis similar to Fig. 2 except that the pumping disk, driving tongue and suction ring are removed. Fig.

- 4 is a plan of the pumping disk showing the suction and discharge ports and the outer end, of the driving tongue between them.

mg hole E.

Figf5 is a plan on a. reduced scale of the suction ends of two pumps when placed together.

Similar letters of reference. indicate'similar or corresponding parts where they occur in the several views.

Our invention includes a base plate A above each end of which upstands a bracket.

Oneof these is called the suction bracket B and the other the discharge bracket O. Protruding horizontally from the inside of each bracket and near the to of the same is a boss D. Through eachv oss and eccentricwith the same is an eccentric spindle bear- Protrudin from the outside and near the top of each racket and concentric with the is end, but with our invention a cheap spindle bearing hole before referred to is a stufling box F. In this is a gland G or in lieu of there being a gland adjusted by studs and nuts as shown, an internally threaded nut gland may be used. The outer ends of each of the said glands protrude and are either threaded internally or externally to receive connections G Turning around each boss before referred to is a cover plate. There are thus two cover plates, and the suction one is marked Hand the discharge one J. Each cover plate is prevented from moving outwardly upon the said boss by a shoulder K. It is prevented. from movinginwardly by a leather Washer L which is secured to the boss D by a holding 7 plate M. This holdin plate M is fixed to the said boss by screws N Fi The said leather Washer L is larger in diameter than the holding plate M and surrounding g. 3) or other means.

the enlarged portionis a looking or jointing ring P. Each one of these rings P, by screws Q or other means, is secured to its cover plate and turnsror rotates with it. The leather washerand the holdin plate each-have an eccentric hole therethrough ofapproximately the same diameter as the eccentric hole E before referred to. Y

Freely turning in each eccentric spindle bearing hole is a tubular spindle. One of these is hereinafter called thesuction spindle R and the other the discharge spindle S.

The outer end of each spindle passes into the stufling boX F before referred to and turns therein. The inner ends of the spindles are connected to or are integral with a pumping disk T which may be centrally situated between the said two spindles. The width of the said pumping disk as also its diameter will depend upon conditions. In its circumference are two ports, the suction port U and the discharge port V (see Figs. 2 and 4). Between the said suction port U and the tubular suction spindle R is a suction passageway each cover.

, attached a driving ring L "the casing is a ton ue end of this is closed y a cover plate D this box is a radial passageway E (see Fig.

inafter referred to. Into this combination hole is passed the inner or headed end A (Fig. 2) of a rectan ular sectioned driving tongue B The sai driving tongue therefore protrudes radially from the said disk.

Attached between each of the cover plates H and J is the pump casing CH The interior of this is larger in diameter than the disk and there is existing between the disk and the interior of the casing a crescent-shaped space (see Fig. 2). Protrudin from the outside of ox D The outer In 1) to accommodate the outer end of the driving tongue which ton ue moves in and out of the passa eway radially as the casing and the pump dis rotate. v

Inside the casin and at each side of the pumping disk is pTaced a ring F. In each such ring is a central hole F which is larger than the s i'ndle to allow of the eccentric travel of t e saidspindle'. At the side of each ring is'also a chamber-Gr into which escaping water passes. The inner surface H of each ring F is pressed against the disk side by adjusting screws J passing through Throu h each ring F is a dlscharge hole K (see ig. 2.)

To the circumference of the casing may be This may accommodate a fiat leather belt or may be 'provided'with sprockets to accommodate a chain. Or it may be rooved to afford a rope guide. Or it may e toothed driven or the casing may be wound in such a manner as to form the armature of an electric the water chamber M motor, in which case it will be electrically driven.

Two of our pum s may be placed suction end to suction en as seen in Fig. 5. The stuffing boxes and the glands G then lead into Into this the suction water through the inlet hole N enters and passes into the suction spindles R. The s indles overhang the glands G' as seen.

ound each end is recessed a thrust late 0 The distance between the said t ust plates is adjusted by means of the adjusting olts P These are prevented from rotating by the stop Q or other means. The said chamber is closed and provided with an inspection cover. V

The cycle of 0 erations with our invention isas follows-T ewater is led to the suction seas-es connection G on the suction gland and from there into the suction spindle R of the pumping disk T. It then passes through the suction passageway W outwardly till it reaches the suction port U when it is liberated into the space existing between the circumference of thesaid pumping disk T and the inner wall of the casing C As this casing rotates the outer end of the driving tongue B drives the inner or-headed end A of the same. This turns the pumping disk T so that the said disk and casing C rotate together. The water drawn in through the suction spindle R as the casing rotates is compressed within the casing and finds exit through the discharge port V in the circumference of the said pumping disk T. It then passes inwardly through the discharge passageway X to the discharge spindle S and then through the connection G The chambers G in the rings F gather any water that may escape between the inner surface of the said ring and the surface of the disk. Centrifugal force throws this water through the discharge hole K (Fi 2) into the suction space inthe casing. similar action to the foregoing takes place when'two suction ends are placed together as seen in Fig. 5 save that the suction water first enters the water chamber M before itenters the suction spindles.

Having now described our invention what we claim as new and desire to secure by Letters Patent is In a pump, a pair of brackets, each bracket having a stuffing-box and a gland in each stuffing-box, a boss on the inner side .of each bracket, a shoulder on each boss, a cover plate for each boss, a leather washer having an enlarged end and retaining said cover plate in place, a plate securing said washer in place, and. a locking ring surro'unding the enlarged portion of said washer, in combination with a casing rotatably supported bei I tween said brackets, a suction disk rotatable with the casing, tubular suction and discharge spindles connected with said disk, and a driving tongue connected with said casing and with said disk.
