WILLIAM F. TRAUDT, OF BUFFALO, YORK, ASSIGNOR TO IABER PUMP COM- PANY, OF BUFFALO, NEW YORK, A CQR-PORATION F NEXV YORK.

PORTABLE POWER-DRIVEN PUMP.

Application filed March 7, 1928.

This invention relates to portable pumps and comprises a pumping unit which can be moved about and hung over the side of a receptacle to pump out liquid therefrom, or set up in a flooded cellar or shallow stream for the same purpose. To this end it consists of a rotary pump and usually an electric motor both mounted .on a light weight bed frame, and adapted to operate in a perpendicular, or approximately perpendicular, position said bed frame being provided with an adjustable suspension hook and an easel-like supporting strut, or other supporting foot.

The best form of apparatus at present known to me embodying my invention is illustrated in the accompanying three sheets of drawings in which Fig. 1 is a front elevation of one form of the apparatus, with parts shown in section.

Fig. 2 is a side elevation showing one form of support for the apparatus in section and broken away and another in broken lines.

Fig. 8 is a detail View showing the pump with a supporting foot for the bed frame, used as shown in Fig. 4c.

Fig. 4 is a side View on smaller scaleof the apparatus, set up for one of the uses for which it is designed.

Fig. 5 is a plan view of another form of foot for the pump supporting structure.

Fig. 6 is a side elevation showing the same applied to a pump structure, and

Fig. 7 is a detail rear elevation of this form of foot, i. e. a view looking from the right hand side of Fig. 5.

Throughout the drawings like reference characters indicate like parts. i

1 is a rotary pump preferably having a central inlet 5 and a circumferential discharge connected to the pipe 6. 2 is a bed frame of light weight, preferably a piece .of channel iron, to which the pump 1 and electric motor 3 are fastened, with the driving shaft 1 connecting the two, so that the motor may rotate the pump. 7 is an eyebolt screwed into bed frame 2 to firmly hold the upper end of discharge pipe 6, so that when. it is attached to a hose or system of piping by a coupling such as the elbow 6", employing a screw connection, the pipe may not be twisted away from the bed frame by any unnecessary force which the operator may apply in making the screw connection.

Serial No. 259,764.

8 is a hook projecting from the backof the bed frame 2 and fastened to the same by bolts 9, 9, the hook being adjustable lengthwise along said bed frame 2-by shiftlng bolts 9, 9, into different holes of the series '9, indicated in dotted lines in Fig. 2. By means of this hook engaging the edge of a liquid receptacle such as is indicated at 18, the entire apparatus may be suspended with the pump immersed in the liquid in said receptacle, the hook being adjusted in position according to the depth of the receptacle.

10 is a switch for the electric motor connections operated by thefloat 11, and connecting rod 12, so that the pump may be automatically stopped when the level of the liquid in the receptacle. reaches a predetermined point.

An additional means of support for the apparatus usable in other situations comprises the strut 13, vertically adjustable in the sleeve 14, where it is held by set screw 15, said sleeve being pivoted to the upper end of the bed frame 2 at 16, so as to form, with said bed frame, an easel-like structure which may be set up in a shallow stream, as shown in. Fig. 4, for the purpose of pumping water therefrom, or lowered into a flooded cellar for the purpose of pumping water out of it. To facilitate this action, the lower end of the bed frame 2 is provided with a laterally extending foot piece 17, which may be bolted thereto, as best shown in Fig. 3.

Still another form of supporting foot is shown in Figs. 5, 6 and 7, where 19 is a circular, metal base plate having the

upright flanges

20 and 21 to which the pump bed frame 2 may be bolted, as shown in Fig. 6, or otherwise fastened. 22 is a backing rib for

flange

21, and 2 is a boss corresponding to the cross section of channel iron bed frame 2, on which the end of said channel iron may rest.

In operating the apparatus, it is hung over the edge of the liquid receptacle by means of hook 8, as shown in Fig. 2, or set up like an easel with the pump submerged in the body of liquid on which it is to operate, as shown in Fig. 4:, or set on the foot plate, as shown in Fig. 6, the parts being ad justed to place the bed frame 2 in a vertical or approximately vertical position so that the motor 3 will not be submerged. When the apparatus is used to pump out a receptacle like a cistern having a wall over, or on the edge of which, hook 8 can be rested, as indicated in Fig. 2, the lower supporting foot, such as 17-, is also useful in pre venting the lower end of the apparatus from swinging away from a vertical line and to hold the entire apparatus in proper position. After the contents of the cistern have been pumped out down to level nearly that of the suction opening of the pump, the apparatus can then be unhoolred and stood up on the bottom of the cistern through the action of the foot 19, the hook 8 then resting against the side wall of the cistern and still contributing to the support of the apparatus.

While I have illustrated an electric motor, other small motors might be substituted as the driving member of the apparatus.

The advantages of the invention comprise its cheapness, lightness, ease of portability and facility for locating in operative position in any one of many diiferent situations, where water has to be removed for emergency purposes, or obtained during a short period of use.

Having described my invention, 1 claim:

1. The combination, with a rotary pump, a motor and a driving connection between the two, of a light-weight bed frame adapted to support said motor above said pump,

and a hook mounted on said bed frame for temporarily engaging any convenient support for the entire structure, whereby it may be suspended from the side wall of a liquid container with the pump submerged in the l quid, said hook being adjustable lengthwise of said bed frame.

2. The combination, with a rotary pump, a motor and a driving connection between the two, of a light-weight bed frame adapted to support said motor above said pump, a transversely extending foot piece on the lower end of said bed frame, and an adjustable strut pivoted to the other end of said bed frame, whereby said structure may be set up in a liquid receptacle with the pump submerged in the liquid.

The combination, with a rotary pump, a

motor and a driving shaft connecting the r two, of a lightweight, narrow bed frame adapted to support said motor above said pump, supporting means mounted on the up per portion of said bed frame adapted for engaging any convenient support for the entire structure, and a supporting foot piece fastened to the lower end of said bed frame and adapted to cooperate therewith and with said upper supporting means to maintain the above described structure in substantially vertical position.
