ENGINE ATTACHMENT.

Application filed January This invention relates to internal combustion engines of that type having a splash system of lubrication and has for its object the provision of an attachment adapted to be mounted at the base of the cylinder block for forming substantial continuations of the cylinders so that the pistons will be enclosed even when they project below the bottom of the block, the advantage being that there will be less oil splashed onto the cylinders and consequently greater economy in oil consumption and a reduction of carbonization and likelihood of fouling the plugs.

An important object is the provision of an attachment of this character which is designed to be installed upon already existing engines with very little trouble, the device being moreover simple and inexpensive to make, easy to install, efficient in use, durable in service and a general improvement in the art.

With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a bottom plan View of a portion of an engine block showing the engine applied,

' Figure 2 is a vertical longitudinal section,

Figure 3 is a vertical cross section on the line 33 of Figure 1,

Figure 4 is a vertical cross section on the line 44 of Figure 1,

Figure 5 is a perspective view of the device detached.

Figures 6 and 7 are views of modifications.

Referring more particularly to the drawings the letter A designates a cylinder block formed with the cylinders I3 and crank case portion C. The letter I) indicates the cam shaft which operates the push rods FM It is well known that the cylinders themselves are separated by a web F at which is pro vided a lug G.

In carrying out the present invention I provide an attachment which is formed preferably as a single casting and which includes an elongated body 10 of a length to be disposed between the bearings H and I on the block. This body is formed with two cylindrical recesses 11 designed to register with. the bores of the cylinders 13 when the body is secured flat against 2, 1924. Serial No. 684,043.

the underside of the block. At its outermost ends the body is cut away as indicated at 12 so as not to interfere with the bearings, and at one side its upper surface is beveled at 13 to lie against the crank case portion C of the block. The bottom wall 14 is formed with elongated openings 15 for the passage of the connecting rods J of the motor, and the body is also formed with openings 16 at the side opposite that having the beveled edges 13 likewise to permit the necessary movement of the connecting rods.

To effect mounting of the device, I pro vide a hole 17 which is formed therethrough in the web portion 18 which is at the center of'the body or between the recesses 11, and through this hole is passed a stud 18 which is screwed into a tapped hole 19 in the block. body has a flat face 20 adapted to lie conformingly against the lug 20 and'projecting from this flat face is a bracket like projection 21 formed with a cavity 22 adapted to engage and receive the lug G, the cavity being of such size and shape as to fit neatly upon this lug.

IVhile it is true that the opposite side of the device might be attached in substantially the same manner, that is: by means of a stud or the like, I preferably form the upper surface of the body at the center of its opposite side with an upstanding projection 22 which fits within a cavity 28 formed originally in the block. This projection 22 has its under surface hollowed out as indicated at 24. The device is designed primarily for use in connection with a Ford engine and it-appears that in the later models the cylinder block is not provided with a cavity 23. In applying my device to this type of block it becomes necessary either to grind or otherwise gouge out the material of the block to define a cavity or else to omit the projection 22 entirely and to rely entirely upon the securing stud 18 or to provide two of such studs one at each side of the engine. These two alternative modifications are illustrated in Figures 6 and 7; the former of which shows the device as held by a single stud, and the latter of which shows the use of two studs.

In the use of the device, it will be seen that when the pistons reach the lower ends of their strokes and project beyond the bottom of their cylinders they will still be enclosed by the attachment except at the The intermediate portion of the cut may 1 emits 12 and it is therefore obvious that on y a limited quantity of oil may be splashed onto the pistons. When the pistons are at any other position, the "attach ment Will operate to'prevent excessive oil;

from being splashed onto the cylinder Walls. As a consequence it is apparent that excessive oiling and Waste of oil together with the resultant disadvantage of carbonization and plug fouling will be prevented while at the same time ample lubrication will be insured; The device Will not in any Way interferewi'th the operation of the engine and it is to be noted that it is simple to make and may be readily applied Without involving any changes inrthe bloclr other than the making of a hole therein.

comprising a body member formed to extend across a pair of cylinders and having flanges registering with and forming continuations of the cylinder Walls, the body member having its bottom and portions of its sides open to accommodate the connecting rod, a projec'tion on one side of the body member fitting Within thespace between the cylinders to preventshifting of the body, a lug on one side of the body engaging upon an existing projection on the cylinder block, 'and a stud passing through said lug.

2. An engine attachment comprising a body 'member adapted for disposition against the bottomof a cylinder block and formed with recesses registering Withthe cylinder bores, the bottoms of the recesses having 0 a'enin'gs for the accommodation of the connecting rods and the ends of the body having cut away portions to expose limited areas of the pistons and means for securing the body in'po'sition, comprising a stud passing through the body and screwed'into a tapped hole in theblock, and lugs projecting from one side of the body and fengageabl'e with an existing project-ion on the block.

In testimony whereof I aflix my signature. a
