Ihis invention relates to a method of mounting a machine base on a concrete foundation as well as to the mounting itself.

Heretofore in mounting a machine base on a concrete foundation it has been customary to grout the machine base in. When it be-x came necessary to remove the machine base for any reason such as for repairs it was necessary to mutilate the foundation to some to extent and sometimes the machine base was even blasted out.

This difficulty is overcome by the present invention in accordance with which a metal sub-base is first grouted into the concrete is foundation and the machine base after being supported in the proper position with respect to the horizontal or vertical is secured to the sub-base in a rigid manner but by means which can be quite easily removed without injury to foundation, sub-base or machine base. 7

To illustrate the invention I have shown in the accompanying drawings and described in v the following specification the mounting of a vertical shaft base for .anoil well pumping power. In the drawings Fig. 1 shows a pumplng power unit in side elevation with the exception of the base, subbase, and foundation which are shown in central vertical. section Fig. 2 is a plan view of the base and subbase with the upper parts of the power removed and the shaft in section, v

Fig. 3' is a vertical section on the line 33 of Fig. 2,

i Fig. 4 is a plan view of half of a modified form of base and subbase with the upper parts of the power removed, 7

Fig. 5 is a vertical section on the line 55 of Fig. 4,

Fig. 6 is a plan view of half of a further modified form of base and sub-base, and

7 is a vertical section on the line 7-? of Fig. 6. r i

A vertical shaft 1 is secured in a base 2 and upon the shaft are rotatably mounted eccentrics 3 and a bevel gear 4 which areconnected together sothat all are driven by the V bevel gear. The base 2 is mounted in a recess 59 5 of a concrete foundation 6. The outer edges oflthe base 2 rest upon a sub-base? which is grouted into therecess 5 of the concrete foundation. The. base and sub base shown" are substantially square, this being-a very desirable form for rigidity and ease of" mounting,

but the invention is applicable to any shape of base and sub-base. Thesub-base 7 has upstanding lateral flanges 8 and at each corner a depression 9.

.When the sub-base 7 has been grouted into the foundation and the base is ready to be mountech the base is set into the recess 5 with its edges extending .over the sub-base and is then temporarily, supported so that the shaft 1 isvertical. The depressions 9eand the space between the corners of the base and the flanges-8' are then filled with a material 10 whichwill solidify and support the base in the position in which it has been temporarily supported. The material 10:lying between the corners of the base and, the flanges 8 holds *the base against lateral shifting. I prefer ,tojuse for thematerial 10 an easily ineltable metal such as lead or babbit, thisbeing poured ininmolten-condition and when all four corners are filled being further driven in by pe'ening with drift-s or other means.- Foundationbolts 11 are anchored in the foundation ,6 and extend up through holes in the corners ofthesub-base 7 and base 2. Thebase 2 is finally clamped down bymeans of nuts 12 screwed onto foundationbolts 111w In the modified form shown'in Figs. 4 and 5- the depressed portions -9:in the corners of the sub-baseare still provided and filled with material 10, but for taking up lateral stresses wedges 1 mounted on stud bolts 13'and h eld bynuts 15 are used. In this case the lateral flanges 8 have a slight outwardfiare corresponding to the;pitch of the wedges 14-.

ENGINE I I In the modification shown in Figs. 6 and 7 the'wedges l l'are replaced by jack screws 16 extending through the flanges 8 andbearing against the corners of the base. The ack screws-l6 are provided with lock nuts 17. In this modificationalso thematerial 10 .is used in the depressed portions 9 for supporting the base 2 vertically but does not extend up along the sides of the base. r g

By means ofthis invention it is possible to mount a machine base just as rigidly as with the old method of grouting it directly into the concrete foundation, but when it is necessary to remove the machine base for any reason this can easily be done by simply removing the nuts 12 and melting out the lead or babbit or loosening the Wedges or jack SCI'GWS.

Having described my invention, I claim:

1. In a device of the class described, a concrete foundation, a unitary metal sub-base permanently secured in said foundation, a machine base resting solely and mounted upon said sub-base, said sub-base having de pressed portions adjacent the edges of said machine base, and fillings of hardened plastic material vin said depressed portions supporting and fixing the position of said machine base with respect to said sub-base.

2. In a device of the class described, a concrete foundation, a unitary metal sub-base permanently secured in said foundation, a machine base resting solely and mounted upon said sub-base, said sub-base having idepressed portions adjacent the edges of said machine base, and fillings of easily meltable metal in said depressed portions supporting and fixing the position of said machine base with respect to said sub-base.
