To all whom it may coofoern:

Beit known that I, Ammo F. MAsuRY, a citizen of the United States, and residingin the borough of-Manhattan of the city of New York, county of'New York, in the'State of New Yor'k,have invented certain new and 1 useful Improvementsin Sheet-Metal Intervtion in nal-Combustion Engines, .ofwhich thefollowing is a specification, reference being had to the accompanying drawings, forming "a' part hereof. i

Thisinvention-relates to internal combusti n casings formed of sheet metal and has for itsgeneral object to provide a construcwhich the sections of the casing may be pressed readily into symmetrical parts from integral blanks and then united per manently to form the complete casing. In:

.ternal combustion engine casings of this type while possessing many mechanical ads vantages over cast structures are diflicultto manufacture in. such form as will'satisfy manufacturing considerations, and at the same tiine give the necessary' .strength and .111 service. The

durability for cooperation improved constructioncontemplates one form of casing in which the cylinder section .walls and crankcase walls are formed of two integral sections united a transverse plane passing substantially through the mld-section of the motor. In

I each section the crank case .walls and cylinder section walls are integral withone an other and the proximate edges of the two sections are flanged to permit their perma-' nent' union and the formation of the unitary engine body- Within the cylinder section walls may be supported the other, elements such as the cylinders and the'top and bot tom plates by which the cylinders are supclearly from the illustrated embodiment, in which,'

concerned with its form or the means for applying it to the improved "casing. The

cylinder section of the casing consists of two symmetrical sections indicated generally by the reference characters a and each of these sections includes side walls a, end walls a integral with the said a for the crank case, and side walls a therefor, all of'the said walls in each such sectionbeing stamped from a single integral blank vices available in the art other way known to the art. In addition to the openings a for the bearings of the crank shaft the walls a fof the crankcase may have stampedtherein suitable handholes a as is usual in crank case'constructions.

Within the engine walls proper there may side walls, end Walls by any suitable defor handling metal. ach section has formed, in the endWalls'a be supported adjacent the top and bottom horizontal plates 6 in which are formed openings 6 alined in the respectlve plates to receive the cylinders c of the motor.

These plates aresupported within the sheet metal .walls of the casing'by riveting, weldtop and bottom plates by some such method. en the partsare'given their permanent set necessarv, of course, that the top and bottom after formation of'the engine body it ismg or otherwise, and the cylinders 0 may be secured intheir respective openlngs 1n the disposed with. relation 7 to the engine Walls and cranlr and the cylinders so mounted in said plates that the cylinders shall be maintained in parallelism and in proper relation to the moving parts of the motor.

The construction described has the ad vantage that the two sections a may be pressed from a single blank of sheet metal, the walls or": the engine and the crank case in each section being integral, and that these tWo sections may be readily united along the transverse line of union indicated by the flanges a. I

It is to be under tood that the invention is not to be limited to the precise form or size of any of the parts mentioned nor to the particular means employed for uniting any of the contracting metallic parts since all such details Will depend upon the character of the motor to be formed and to metal Working considerations which may best be optional with those skilled that particular art.

I claim as my invention:

1. A sheet metal casing for an internal combustion engine formed of sections united along transverse planes, the Walls of the cylinder section and the crank case in each section being formed in one integral piece from a single piece of sheet metal.

2. A sheet metal casing for an internal combustion engine formed of two sections united along a transverse plane passing substantially through the mid-section of the engine, the walls of the cylinder section and the crank case in each section being formed from a single piece of sheet metal.

3. 1%. sheet metal casing for an internal combustion engine formed of two sections united along a transverse plane passing substantially through the mid-section of the engine, the Walls of the cylinder section and the crank case in each section being formed from a single piece of sheet metal, with openings formed in the end walls of the crank case to receive the crank shaft.

4. A sheet metal casing. for an internal combustion engine formed of sections united along transverse lanes, the Walls of the cylinder section andthe crank case in each section being formed in one integral piece from a single piece of sheet metal, and top and bottom plates secured permanently Within the engine Walls and having openings to receive the cylinders.

5. A sheet metal casing for an internal combustion engine formed of sections united along transverse planes, the Walls of the cylinder section and the crank case in each section being formed in one integral piece from a single piece of sheet metal, with flanges formed along the proximate edges of adjacent sections, and means to secure the flanges together.

This specification signed this 19th day of June, A. D. 1917.
