Claims.

This invention relates to supporting structures for machines and more particularly to such structures which are used in mounting dynamoelectric machines.

In the design of supporting structures for machines, it is frequently desirable to provide an arrangement which permits the supporting element to be mounted in any one of four positions, namely, conventional, inverted, right side wall, or left side wall, without altering the relative position of the machine. It is also desirable to provide a supporting structure which can be permanently secured to an external surface and which permits removal and replacement of the machine without removal of the supporting element. Such an arrangement is particularly desirable in the design of certain dynamoelectric machines such as fractional horsepower electric motors for installation in gasoline pumps since difierent manufacturers may specify different locations for securing the motor, for instance, inverted suspension, conventional mounting, or supported by the right side wall or the left side wall of the pump. In either case, the motor is required to have the same relative position and it is, therefore, necessary to provide a supporting structure which can be used with the same motor in any one of the four mounting positions. It is also desirable in the interests of economioal construction to provide a supporting arrangement which directly engages the clamping bolts of the motor.

An object of this invention is to provide an improved supporting structure for a machine.

Another object of this invention is to provide an improved supporting structure for a machine which can be mounted in any one of four positions without changing the relative position of the machine.

A further object of this invention is to provide an improved supporting structure for a machine which permits removal of the machine without removal of thesupporting element.

Further objects and advantages of this invention will become apparent and the invention will be better understood by reference to the following description and the accompanying drawing. ihe features of novelty which characterize this invention will be pointed out in the claims annexed to and forming a part of this specification.

In the drawing, Fig. 1 is a side elevational view, partly in section, illustrating the improved supporting structure of this invention utilized to support a motor in an inverted position; Fig. 2

is .a view in perspective of the base member of Fig. 1; Fig. 3 illustrates in detail the slotted opening and washer feature of this invention; and Fig. 4 is a side eleva'tional view showing the application of the improved supporting structure of this invention for conventional mountin of a motor.

In accordance with this invention, there is provided a U-shaped base member, one leg of which is provided with two holes which slip over one end respectively of two clamp bolts which are secured to the machine. Ifhe other leg of the base is provided with two slotted openings which fit over the other ends respectively of the two clamp bolts. The neck of the slotted opening is slightly wider than the diameter of the clamp bolts and the interior portion of the slot is substantially larger than the width of the neck. After the base is slipped into place, a washer is placed over the end of each clamp bolt and fitted into the interior portion of the slotted openings. Conventional clamping nuts and washers are then mounted on each end of the clamp bolts. Thus, the weight of the machine is supported on one side by engagement of the holes in one base leg with the clamp bolts and on the other side by the base through the washers in the slotted openings rather than by friction between the clamping nuts and base.

Referring now to Fig. 1, there is shown a fractional horsepower motor I provided with conventional end shields 2 and a shaft extension -3. Each end shield is provided with a, plurality of equally spaced projections 4 on the outer periphery thereof and formed. integral therewith. The end shields 2 are secured to the central portion 5 of the motor by a plurality of equally spaced longitudinal clamp bolts 5 which extend through openings in the projections 4. These clamp bolts also serve as mounting members, as will be hereinafter described. The ends I and 8 respectively of the clamp bolts 6 are on the exterior of the end shields 2 and spaced from the outer periphery thereof. The ends 1 of the clamp bolts 6 are threaded to engage tapped holes in the corresponding projections 4 and to receive-clamping nuts l0, as will be hereinafter described. The ends 3 of the clamp bolts are threaded to receive clamping bolts 9.

,A U-shaped base member H supports the motor I and is provided with a central portion i2 adapted to be mounted on an exterior surface I3 in any convenient manner, such as by bolts II. The base member H is provided with leg portions 15 and it which respectively engage Referring now to Fig. 2, the base member I i i is shown provided with a plurality of slotted openings H in its central portion l2 through which the mounting bolts i4 project. The leg portion !5 is provided with two openings l8 (only one being here shown) which are only slightly larger than and are adapted to slide over the ends 1 of two of the clamp bolts 6. The other leg portion [6 of the base member II is provided with two slotted openings 19. Each of these openings is provided with a neck portion 20 which is only slightly Wider than the diameter of the ends 8 of the clamp bolts 6 and an interior portion 2| which is substantially wider than the width of the neck portion 20.

To mount the motor I on the base i I, washers 22 are positioned on the ends 8 of two of the clamping bolts 6 adjacent the clamping nuts 9. The ends I of the two clamping bolts 6 are then inserted through the two holes iii of the leg portion It: and the other ends 8 are slid through the neck portions 20 of the slotted opening 19 into the interior portions 2!. Two washers 23 are next positioned on the ends 8 of the clamp bolts 6 so that they fit snugly within the interior portions 2i of the slotted openings 22. The clamping nuts are then placed on the ends I securing the leg portion I tightly against the projections 4 and washers 24 and clamping nuts 25 are positioned on the other ends 8 to hold washers 23 in place and to secure the leg portion l6 against the clamping nuts 9.

Referring now to Fig. 3, it can be readily seen that the weight of the machine regardless of the position of the base member ii is supported on one side by the leg portion 15 of the base I l and on the other side by the washer 23 within the interior portion 2| of the slotted opening It ing bolts e and the clamping nuts 25, washers 24, and washers 23 from the other ends 8. The ends 8 of the clamp bolts 6 can then be merely slid out of the slotted openings I9 and the ends I pulled out of the holes l8. Thus, removal and replacement of the motor does not necessitate I dismounting of the base member ll.

While there is illustrated and described a particular embodiment of this invention, modifications thereof will occur to those skilled in the art. I desire it to be understood, therefore, that this invention is not to be limited to the particular arrangement disclosed and I intend in the appended claims to cover all modifications which do not depart from the spirit and scope of this invention.

What I claim as new and desire to secure by Letters Patent of the United States is:
