Application September 7', 1937, Serial No. 162.582 s claim... (ci. zia-za) 'Ihis invention relates to a l vertical motor mounting more particularly for mounting'. a vertical motor for driving a vertical pump.

The usual motor driven motor pump is direct connected in alignment with a special motor designed to operate with its shaft in a verticalposition. These pumps are installed in wells of various depths and operate against various heads even in the same well as thel water table rises and lowers therein. Due to the fact that the motor is direct connected, it is impossible to change the transmission ratio betweenv the motor and the pump and the result is that in some cases the motor is far in excess of the power required by the pump.

The principal object oi' this invention is to provide a mounting i'or supporting a vertical motor in parallel relation to thejpump in such a manner that the motor can be quickly and easily changed if desired and so that the motor pulley can be quickly and easily removed and replaced to adjust the power and speed in proportion to the pump requirements.

While the invention is particularly valuable as applied to vertical shaft pumps, itwill undoubtedly be i'ound valuable for other purposes.

Other objects and advantages reside in the detail construction of the invention, which is designed i'or simplicity, economy. and efficiency. These will become more apparent from the iol lowing description.

In the following detailed description oi' the invention reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views oi' the drawing and throughout the description.

Fig. 1 is aside elevation oi a typical installation upon a vertical pump.

Fig. 2 is a plan view of the pump mounting with the motor and pump removed.

Fig. 3 is an end view oi' the mounting with the motor removed. I

Fig. 4 is a detail view oi an alternate form oi trame adjustment.

A typical vertical shaft motor is indicated at Ill driving a vertical shaft pump." through the medium of a plurality oi' V-belts I2. 'Ihe V- 'belts extend from a drive pulley Il on the motor to a driven pulley I4 on the pump.

The improved mounting 'consists oi' a base frame II preferably formed oi' two longitudinal channel members connected adjacent their extremities by cross-channels I6. For the usual pump a sub-trame Il is secured on the base chanzontal angle member nels il provided with crossvbeams i8 for receiving and attaching the base of the pump II.

The motor is mounted in a motor carriage which consists oi' two L-shaped side frames each formed'oi' a vertical angle member I8 extending 5 at right angles from the extremities oi' a horiand connected at their extremities by a diagonal brace member 22. The angle members are joined together by welding to a gusset plate 2| or in any other desired man- 10y ner. The two side frames are tied together by means of horizontal cross-bars 2l which serve as mounting plates for the base oi' the motor Ill.

The angles 20 are spaced-apart just suiiiciently to slip/down over the channels I5 and are se- 15 cured thereto by means o! clamp bolts 24 which extend through slotted openings 25 in the angles 20. A pair of jack screws ,2B are threaded through a cross bar 26 at the end of the subirame l1 .and bear at their extremities against 20 the upright angles il to prevent the motor frame from approaching the pump and to provide means for tightening the belts i2. After the belts have been brought to the proper tension, the bolts 24 are tightened. Lock nuts26 may be placed on the 25 jack screws 25 to hold the device in this preset position.

Should the water in the well descend so as to increase the load upon the pump. the operator can remove the motor pulley I3 and replace it 30 with a smaller pulley. He then, by loosening' the bolts 24, slides the entire motor carriage away from the pump to again tighten the belts on the smaller pulley to reduce the speed oi' the pump 35 and increase its power.

In Fig. 4 an alternate method of mounting the jack 'screws is illustrated-for installations which do not require the sub-frame il. .In this form the jack screws are threaded through angle clips 2l welded or otherwise secured directly on the top of the channels I l.

It is desired to call attention to the fact that the motor is mounted on the inside of the carriage so that its center oi' gravity is always over .4,5l

the base oi' the carriage. The assembly will therefore remain upright even with the assistance of the bolts 24.

While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope oi the appended claims, without departing from-the spirit of the invention.

yHaving thus described the invention, what is claimed and desired secured by Lettera Patent isz- '1. A motor mounting for pumps comprising: a. main frame; means for supporting a pump on said main frame; a motor carriage consisting of two side frames. each side frame comprising a horizontal, flanged angle member iltting over the side edges of said main frame; a vertical member arising from one extremity of each horizontal angle member; cross members connecting the vertical members oi said side frames; a motor mounted on said cross members and projecting over and above the horizontal angle members with its shaft at right anglesto the latter.

2..A motor mounting for pumps comprising: a main frame; means for supporting a pump on said main frame; a motor carriage consisting of two side frames, each side frame comprising a horizontal, anged angle member iltting over the side edges of said main frame; a vertical member arising from one extremity o1' each horizontal angle member, and a diagonal member connecting the other extremities of said horizontal and vertical members, said side frames being connected by cross members; and means for mounting a vertical shaft motor from the vertical mem- 4 bers of said side frames.

3. A mounting for supporting a vertical-shaft motor in adjustable parallel relation to a vertlcal-shaft pump comprising: two longitudinal base frame members; cross members holding said longitudinal members in parallel relation; means for mounting a pump at one extremity of and between said longitudinal members; .a pair of horizontal angle bars, there being one bar lying on each longitudinal member and extending l ,said horizontal bars acting to guide them along said longitudinal members.
