United States Patent 3,153,338 MGTfiR ACQESSQRY BRAQKET AND PUMP Burl L. Qheely, 3534 W. Rosecrans Ave, Hawthorne, (Calih, assignor of one-half to Usher l). Rudik, Los Angeles, (Calif.

Filed Dec. ill, 1961, Ser. No. 158,189 Claims. (Cl. 193218) This invention has to do with mounting brackets for attaching accessories to small gasoline engines and other motors.

An object of the invention is to provide a novel device in the nature of a combined mounting bracket and pump housing for attachment to a small internal combus tion engine or to an electric motor.

Another object is to provide such a device adapted to mount on a motor in position with the pump housing portion of the device on the axis of the motor shaft and having means for mounting a belt-driven device to one side of such axis.

A further object is to provide a simple, compact, strong and readily manufactured device of the type indicated which can be formed in the main part as a single metal casing.

These and other objects will be apparent from the drawiugs and the following description. Referring to the drawings:

FIG. 1 is a side elevational view of a motor accessory bracket as it appears when mounted on a small gasoline motor, the latter being shown in broken lines;

FIG. 2 is a side elevational view of the bracket and pump housing on line 22 of FIG. 1, but partially broken away to show parts in section;

FIG. 3 is an end elevational view of the inner end of the device as on line 3-3 of FIG. 2; and

F116. 4 is a sectional view on line 4-4 of FIG. 2.

More particularly describing the invention, numeral 11- generally designates a motor accessory bracket and pump embodying the invention which is adapted to be attached to the side of a motor, such as the small internal combustion engine 112 shown in broken lines in FIG. 1.

The combined bracket and pump comprises a central,

substantially cylindrically shaped body 1.4 which extends somewhat less than 270 circumferentially, terminating in

edge portions

15 and 16 which define an opening 18 to the interior of the body. At the outer end of the body I provide a flange 26 which extends radially outward and is provided with circumferentially spaced enlargements 21, these being apertured at 22 to receive mounting bolts. Also, at the outer end of the body, I provide an inwardly extending dished wall 24 which is centrally iaper tured at 25 to receive a shaft 26. The opening is counterbored at 2'7 to mount a rotary seal 28 of the mechanical type. The Wall 24 is shaped to act as a side wall of a pump casing 29. Shaft 26 may be fitted with an impeller 3d of any suitable design and this is housed within the pump casing which includes an outer casing member 32 having a centrally disposed inlet 33 and a tangentially disposed outlet section 34. Member 32 is bolted to flange 2d of the body by means of bolts 35 which fit into threaded holes 36 in member 32 disposed to register with holes 22 in the flange of the body.

At its inner end, the body is provided with an end flange 38 which extends radially outward and generally follows the contour of the body 14 except at one side where it is extended at 39, having a straight, horizontal lower edge 40 and an inclined end edge 41. Holes 42 are provided in the flange for the purpose of attaching the same to a motor 12 by bolts, not shown. A mounting shelf 44, reinforced by gussets 45, extends laterally of the flange extension 39 and'oppositely to the body 14. The shelf includes a recessed central sec-tion 46A, and machined pads 46B and 46C, which are in a plane parallel to a plane tangent to the shaft. The shelf is slotted at 47 to receive mounting bolts, and in FIG. 1 an air compressor 49 is shown mounted on the shelf by way of example.

The accessory mounted on the shelf 44 can be beltdriven from the shaft 2.6 and for this purpose the latter is fitted with a sheave or pulley 5*). A belt 51 is shown trained around this and a sheave 52 on the accessory 49. As shown in FIG. 2, the shaft 26 is the motor shaft, or an extension thereof Although I have illustrated and described a preferred form of my invention, I contemplate that various changes and modifications can be made therein without departing from the invention, the scope of which is indicated by the following claims.

I claim:

1. A motor accessory bracket device comprising a semicylindrical body open at one side, a radial flange at one end of said body for attaching the same to a motor, said flange extending laterally of said body for a substantial distance on the same side thereof as the open side of the body, a shelf extending laterally of the end of the extended portion of the flange in a direction oppositely to said body, a dished apertured end wall at the other end of said body, and a casing attached to said body beyond said end wall and cooperating with said end wall to define a pump impeller chamber.

2. The device set forth in claim 1 in which a shaft is journaled in said end Wall, in which said shaft carries a pump impeller in said chamber, and in which a sheave is fixed to said shaft in the region of the open side of said body.

3. A unitary motor accessory bracket adapted to be mounted upon the end of a motor having an externally projecting motor shaft, comprising a tubular body characterized by a relatively thin wall and a space within the body of relatively large cross sectional area, an annular external mounting flange at one end of the body, said flange having an extension portion, and a shelf carried upon and projecting rearwardly of the extension portion of the mounting flange adapted to carry an accessory, said shelf lying in a plane generally parallel to a plane tangent to the axis of the body and being located to one side of a plane extending radially and longitudinally of the axis of the body and extending normal to the plane of the shelf, said body having a relatively large opening through its wall facing the general direction in which said extension portion of the mounting flange projects, whereby to accommodate a belt trained around the she-ave of the accessory mounted on said shelf and around a sheave within said body and on the motor shaft projecting thereinto through the inner end of the body.

4. The bracket set forth in claim 3, in which said body is cylindrical.

5 The bracket set forth in claim 3 in which said body has a centrally apertured end wall and a peripheral flange at its other end, and in which a casing is attached to said a peripheral flange cooperating with said end wall to define a pump impeller chamber.
