Application filed April 7, 1914. Serial No. 830,158.

To all whom it may concern:

Be it known that I, WILLIAM DOUGLAS CARTER, a citizen of the United States, residing at San Jose, in the county oi Santa Clara and State of alifornia, have invented certain new and useful Improvements in Centrifugal Pumps, of which the following is a specification.

My invention relates to the clam of centrifugal-pumps, particularly to those of the horizontal type.

The object of my invention is to provide for supportin and stood ing the pump on the suction si e of its casing, under all conditions of the angular adjustment of the discharge and of the suction of saidpurnp.

To this end ,my invention consists in the novel construction and combination of parts which I shall now fully describe by reference to the accompanying drawings, in

which-- Figure 1 is an elevation, partly broken, of my pump, showing the position of the suction and discharge as said pump is normally shipped out. Fig. 2 is a perspective view of the pump, showing both suction and discharge turned to an "angle difl'erent from that shown in Fig. 1. Fig. 3 is a fragmentary view showing the steadying foot as a separate. iece from the cap-plate of the casing and olted thereto, instead of being made integral therewith as it appears 'in Figs. 1 and 2.

1 is a base having a pedestal. 2 is the pump casing s-u ported by said pedestal, and having a perip eral discharge 3. 4 is the cap-plate of the casing and 5 is the suction elbow. The assemblage of these parts is as follows: The pump casing is carried by the base pedestal and is rotatively adjustable relatively thereto. The connection here shown is formed by the bolts 6, the heads 7 of which are fitted in an annular groove 8 in the casing. The cap-plate is rotativel adjustable with respect to the casing, sai connection being formed by the bolts 9, the heads 10 of which are fitted in an annular roove 11 in the casing. The suction-elbow 1s also rotativelv adjustable with relation to the cap-plate, this being possible by reason Specification of Letters Patent.

impeller, and 17 is the drive-shaft pulley.

18 is a supporting foot, with. which the cap-plate 1 is formed or provided. In Figs. 1 and 2 it is shown integral with the plate. In Fig. 3 it is shown as a separate piece bolted to said plate. This foot always rests on a foundation whether said foundation be an extension of the base, or, as here shown a floor, regardlessof the angular position of the suction or the discharge. This results fromthe fact that the cap-plate which carries it has such a connection both with the casing on one side and with the suction elbow on the other side, as will enable it to rest its foot on the foundation under all circumstances, while permitting the casing to be turned to adjust its discharge to'any position desired, and permitting the suction elbow to be also turned to any desired position; or to permit both suction and discharge to be adjusted to suit any conditions found most practical in setting up the pump. The pump is thus provided with a permanent outer support on the suction side of its casing which avoids the usual ex edient of temporarily blocking up under t e casing.

I claim 1. In a centrifugal-pump the combination of a base having a pedestal; a pump 'casing having a discharge; a connection between the pedestal and the pump casing adapted for the rotative adjustment of said casing to vary the angular position of its discharge; a cap-plate having a supporting foot adapted to rest on a foundation; a connection be- Patented Nov. 24., 1914.
