GON'DENSATION PUMP AND RECEIVEB Filed May 31, 1927 I INVENTOR Bznj'am'm fikidmom Jr.

Pawnee May 28, 1929.



Application filed May 31,

a condensation pump and receiver, particularly. adapted though not necessarily limitedin its use in connection with a heating system, and one of the objects of the invention is to so'construct and arrange a condensation pump and receiver in which pump bearings, flexible couplings and supporting base for the various parts will be eliminated, thereby resulting in a considerable saving in the cost of manufacture and requiring a small floor space for installation.

In apparatus of this charactep it is desirable, and in fact quite important, to establish a low water line. Heretofore it has been frequently necessary' .to install the apparatus below the floor level and this is obviated to a large extent in the present invention by dispensing with the use of a supporting base and considerably lowering gravity intake to pump, the pump being of the vertical type allowing the impeller to be located at a lower point thereby making it practical to establish a low working level in 2 the receiver.

In the drawing- Figure 1 is a view partly in section, partly in elevation and partly broken away of a pump embodying the principles of this in- 3 vention and showing the same in connection with a receiver.

Figure 2 is a view in elevation of the pump unit to which any source of supply maly be connected.

eferring more particularly to the drawing the numeral 10 designates a receiver or container which is supported preferably by two short feet or projections 11, which rest directly uponthe supporting surface or floor '12. These two feet are disposed near the center of gravity of the receiver. A pump casing13 is provided with an inlet opening 14 and a flange 15 encompasssing the opening. The casing is supported by means of a foot or projection 16 located near the center of gravity of the casing and rests upon the floor or supporting surface 12.

The flange 15 is connected directly'to a flange 10 on the wall of the receiver 10 by means of suitable fastening devices 16 such as bolts or the like. The flange 10 surrounds an outlet 17 of the container and which outlet 17 communicates with the in let 0 ning 14 in the pump casing 13.

' en the pump casing 13 is thus secured 1927. semi No. 195,403.

to the receiver 10 the entire structure will be supported by a three point support formed by the feet or projections 11 and 16, thereby obviating the necessity of supporting bases and eliminating strains on the castings.

The pump casing 13 is provided with a discharge outlet 18 around which a flange 19 is arranged, and which latter flange is adapted to be secured to a pipe or the like for conveying away the liquid delivered from the pump casing through said outlet.

An impeller 20 is arranged within the casing 13 and is connected with a shaft 22 of a motor 23 preferably by a non-corrosive rigid coupling 21, preferably by telescoping the shaft into the coupling and then securing them by means of a fastening device 24, such as'a screw, bolt or. the like.

With this construction and being thereby able to locate the impeller at a low point in the casing so that the impeller will be rotatable about a VGItlCfil'flXlS, it is possible to establish a low working level for the pump.

The shaft or coupling 21- passes through a suitable stufling box 25.

The motor -23 is supported b the casing of the pump preferably upon a ormation or supporting structure 26 to which the'motor casing is directly fastened preferably by means of bolts or the like 27, thereby rendering it ossible to readily remove the same when desired.

The supporting structure 26 is preferably connected with the top 28 of the pump casing, the latter being preferably removablysecured in positionby fastening devices 29.

The support 26 may be of any desired construction either as an annular member or as separate uprights, but when formed as an annular member suitable openings 30 are provided therethrough to permit ready access to the coupling device 24 and the stufling box 25.

The im eller will be suspended-by the motor sha t with the result that pump bearings will be eliminated.

In Figure 1 the pump shown in connection with a receiver hile in Figure 2 .the

pump is disclosed as a single and separate unitadapted to be connected to any suitable source of supply. In the latter' form of the invention any suitable number of supports or projections 16 may be employed to maintain the pump elementin proper position for use.

With this im roved construction the parts to be accurate y machined are light and easily handled and assembling simplified.

What is claimed as new is A condensation pump and receiver embodying as a unitary structure a receiver having a discharge outlet adjacent its bottom with a flange engaging surface encomassing said outlet, a pump casing having an inletand a flange encompassing said inlet, means securing said flange directly to said surface, said inlet communicating with said outlet, the casing of the pump being disposed in close proximity to the supporting surface for the unit, said pump embodying an impeller rotatable about a vertical axis, and a motor supported directly by the pump casing, said impeller-being located adjacent the bottom of the casing and suspended by the motor shaft, whereby a low working level in the receiver will be obtained.-

In testimony whereof I have signed my name to this specification, on this 27th day of May, A. ,D. 1927.
