TO UNION STEAI/lv PUMP COMPANY, OF BATTLE CREEK,

ROTARY PUMP.

n To all whom t may concern:

' v Y Beit known that we, KARL D. SMITH and BERNARD SAMELsoN, citizens of the United States, residing at Battle Creek, count of Calhoun, and 4State of Michigan, an at 'New Yorkcity, State of New York, respectively, have invented certain new and useful Improvements in Rotary Pumps, of lwhich the following is a'speciiication.

This invention relates to improvements in rotary pumps,

' The main object of our invention is to provide an improved rotary pump well .adapted for the pumping of milk which does not have a churning action on the milk, is of large capacity, and a structure which facili- Itates ready cleaning. v

Furtherobjects, and objects relating to structural f details, will deiinitel appear 420 yfrom the detailed descri tion to fo low.

We 'accomplish the o' jects of our inven- Jtionby the devices and means described in thefoll'owing specification. The invention Clearly defined and pointed' out in the aejgc'laims.

A structure which is a preferred embodiment of our invention is 'clearly illustrated .in the accompanying drawing, forming a part. of. this specicatlon, in which: ipumpmainly in Vertical central section,'the

rotorlbei'ng shown in full lines for convenience in illustration.

Fig. II is a detail front view with the outer casing member removed.-

Fig. III is a detail'section on a line corresponding to line 33 of Fig. I.

In the drawing, similar reference characters refer to4 similar parts throughout the several views. Referring to the drawing, we preferably provide a yoke-like frame 1. The arm 2 of the frame 1 is adapted to receive the supporting hub-like projection 3 of the inner casing member 4. This inner casing member is internally cylindrical and is provided with a tangentially disposed outlet 5, to which the delivery pipe 6 is connected.

The outer casing member 7 is adapted to fit within the inner casing member and has an overlapping rim 8 provided With ears 9 for the bolts 10 by means of which the outer casing member is detachably secured to the inner. The outer casin member has an in- Wardly ared axially 'sposed inlet exten-V Specification of Letters Patent. l

- sion 11 to which the supply-pipe 12 is secured. The supply pipe 12 is mounted for quick detachment, being provided with a collar or flange 20 secured to the inlet exgnsion 11 by means of the flanged coupling 60 The rotor shaft 13 has pulleys 14, one of which is loose .and the other fixed to the shaft. The rear end of this shaft is mounted in a Ibearing 15 carried by the arm 65 16 of the yoke-like, frame. The other end extends through the hub portion 3 of the inner casing member, a bushing 17 being provid-T therein,

The rotor comprises a pair of fiat oppositely disposed blades 18 formed integrally with the hub 19 which projects int'o the inlet extension 11, the bladesv being iared ork widenedA at 20 to extend into the hub,- see Fig. I.

The shaft 13 is providedwith a packing .22 and packing gland 23 threadedl upon the v hub-like projection 3 of the casing.

Withthis form and arrangement of parts', the structure may be quickly` assembled and disassembled for use or for cleaning, and, further, the pump may be used for pumping `milk without van objectionable churning ac- A tion thereon.

Having thus described our invention, what we claim as new and desire tosecure by, Letters Patent, is:

1. In a rotary pump, the combination of a supporting frame, a casing comprising an inner member having a tangentially disposed said frame, and an outer member detachably mounted upon theinner, said outer portion being provlded with an axiallydisposed inwardly fiared inlet extension, a rotor shaft having a bearing in the said hub portion of said inner member,vand a single pair 0`- oppositely disposed flat rotor blades'provided with va hub mounted on said shaft to roject into said inlet extension, theblades eing widened at their inner ends to the outer end of the hub.

2. In a rotary pump, the combination of a casing comprising an 4inner member having a peri herally disposed outlet, and an outer mem er detachably mounted upon the inner, said outer ortion being provided with an axially disposed inwardly ared inlet extension, and a rotor having a single pair of oppositely disposed at rotor blades `llc provided with' a hub projecting into said '4.
