L. w. ALFRED ENGINE MOUNTING BRACKET Filed Aug. 4; 1942 WiNVw.

Lawreg e fr Patented Sept. 22, 1942 UNITED STATES ATENT OFFICE (Granted under the act of March 3, 1883, as

amended April 30, 1928; 370 0. G. 757) 3 Claims.

The invention described herein, if patented, may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.

The present invention relates to mounting brackets, and more specifically to a novel and improved design of engine mounting bracket adapted to support any one of numerous types of internal combustion engines.

In the maintenance of military motor vehicles it is the universal approved practice to run in every vehicle motor that has undergone extensive repairs in order to avoid any possibility of the motor being damaged by improper use after repair, and also to serve as a check to determine that the motor is functioning properly before being released for service. This is done in army maintenance shops by mounting the motor on some type of engine stand that will serve as a satisfactory base to support the motor during its run-in period. Inasmuch as each shop must of necessity service many and various types of vehicles it has been found difficult to provide any single design of engine stand that could be used for all of the various types, sizes and models of motors that must be serviced.

One of the problems incident to the provision of the universal engine stand has been that the mounting surfaces of different types of motors differ widely, some being horizontal, some vertical, and some at different angles. Also, some are parallel with the motor, others at right angles or almost any intermediate angle.

It is therefore the specific object of the present invention to provide an engine mounting bracket arranged and adapted to support any type of internal combustion engine irrespective of the location or angular position of the mounting surfaces or mounting bolts thereof.

Referring now more particularly to the drawing wherein the present preferred embodiment of this invention is disclosed:

Fig. 1 is a sectional View of an engine mounting bracket constructed in accordance with the teachings of this invention, and

Fig. 2 is a side elevational view thereof.

The type of bracket illustrated in the present drawing is intended to be used on any one of several types of adjustable engine stands so that the individual brackets may be positioned against the mounting surfaces of any one of different types, sizes and models of internal combustion engines, but the subject matter of this application is limited to the bracket with which the final 55 connection between the'motor and the stand is accomplished.

The bracket is mounted on the upper end ofa supporting column ll which'has a reducedportion l2 at its upper extremityto provide a supporting shoulder l3 to receive the lower flat surface M of the main bracket castinglfi. The bracket casting 15 comprises a generally rectangular metal block having a vertical bore IE5 at its lower end in order to fit over the reduced portion 12 of the supportingcolumn. The bracket casting is secured in position on the column bya threaded set-screw l1 extending through the wall l8 of the [bracket and into an annular groove I9 on the reduced upper portion of the supporting column. The arrangement is such that the setscrew ll may be loosened sufiiciently to permit free rotation of the bracket casting l5 on the upper end of the supporting column or may be tightened down to the bottom surface of the groove l9 to lock the bracket in any position with respect to the column.

The bracket casting It includes two side wall portions 2| and 22 spaced apart from each-other to define a central slot 22, and a cross-pin 23.ex-

tends between these side portions to provide a pivotal mounting for a shiftable motor bracket arm 24. The bracket arm 24 includes a flat upper surface 25 adapted to bear against the supporting surfaces'of any usual type of internal combustion motor and a bolt hole 26 so that the motor may be bolted to the arm.

It has been heretofore mentioned that one of the objects of the present invention was to provide a bracket or such design and construction that it .will accommodate internal combustion motors of all types, irrespective of the location and angular position of the mounting surfaces. This is accomplished by the present construction, since the combination of the pivotal movement provided between the cross-pin 23 and the motor mounting arm 24, together with the pivotal movement provided by the connection between the bracket casting [*5 and the supporting column ll permits the bolting surface 25 and the bolt hole 26 to assume any angular position.

The mounting arm 24 is also provided with an adjustable locking means so that the arm may be limited in its movement around the pivot 23; the locking means comprising a threaded machine screw 2'! extending through the wall l8 of the bracket casting l5 and having a rounded end portion 28 arranged to bear against the curved inner surface 29 of a limiting lug 3! formed integrally with the motor-supporting arm 24. The inner surface 29 of the limit lug 3| is of such curvature as to bear against the end 28 of the cap screw 21 in an approximate right angle relationship, irrespective of the angular position of the mounting arm 24. If desired, the structure may also include a machine screw 32 extending through one of the side walls 21 to bear against the flat side surface of the mounting arm 24 and thus assist in clamping the arm in any desired position, either below the horizontal position illustrated in Fig. 1, or above.

From the foregoing it will be apparent that the provision of the particular structure illustrated in the drawing provides a simple and rugged universal engine mounting bracket capable of assuming any angular position and thus adapted to engage the motor mounting surfaces of any one of numerous different types and models of internal combustion engines. It is believed, however, that while the construction illustrated in the drawing is the most satisfactory for the purpose, yet certain minor modifications, may be made without departing from the spirit of the invention, the scope of which should be limited only by the terms of the appended claims. 7

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1-. In an engine mounting bracket, in combination, a supporting column, a bracket body portion, a vertical pivot inter-connecting the bracket body and the supporting column; together with means to maintain the bracket body in position on said column; a horizontal pivot pin carried by the bracket body, and a motor mounting arm mounted on said pivot pin, the arm including a fiat mounting surface and a bolt hole adjacent the outer end of the arm and means to limit the pivotalmovement of the arm with respect to the body portion, said means comprising a limiting lug on said arm and a machine screw on said body portion adapted to engage the surface of the limiting lug to adjustably support the mounting arm'in any one of a plurality of angular positions with respect to the supporting column.

2. In an engine mounting bracket, in combination, a supporting column, a reduced cylindrical portion of the upper extremity of said column, and a horizontal bearing surface at the lower end of said reduced cylindrical portion; said reduced cylindrical portion including an annular groove; a bracket body portion consisting of a pair of side walls spaced apart from each other at their upper extremities, a rear wall interconnecting said side walls and a solid lower portion having a vertical cylindrical recess in pivotal relationship with the reduced portion of the supporting column so that the lower surface of the body may bear against the horizontal bearing surface of the supporting column together with means to maintain the bracket bodyin position on said column; a pivot pin extending between the side Walls of the bracket body and a motor mounting arm mounted on said pivot, the arm including a flat mounting surface and a bolt .hole adjacent the outer end of the arm. 3. In an engine mounting bracket, in combination, a supporting column, a reduced cylindrical portion of the upper extremity of saidcolumn, and a horizontal bearing surface at the lower end of said reduced cylindrical portion; said reduced cylindrical portion including an annular groove; a bracket body portion consisting of a pair of side walls spaced apart from each other at their upper extremities, a rear wall inter-connecting said side walls, and a solid lower portion having a vertical cylindrical recess in pivotal relationship with the reduced portion of the supporting column so that the, lower surface of the body may bear against the horizontal bearing surface of the supporting column, together with means to maintain the bracket body in position on said column; a pivot pin extending betweenthe side walls of the bracket body, and a motor mounting arm mounted on said pivot, the arm including a flat mounting surface and a bolt hole adjacent the outer end of the arm; and means to limit the pivotal movement of the arm with respect to the body portion, said means comprising a limiting lug integrally formed with said arm and having a curved inner surface and a ,machine screw in threaded engagement with the rear wall of the body portion of the bracket and adapted to engage the inner surface of the limiting lug to adjustably Support, the mounting arm in any one of a plurality of angular positions with respect to the supporting column.
