9 els in one direction, so that only one wall of veach of the cylinders and one side of each of the pistons is properly lubricated. It may,

therefore, be; considered the object of this invention to provide a simple means for direct,-

ing a lubricant splashed'by the cranks against the thrust side of the motor, that is,t he side of thecylinder and piston that receives the most wear during the power stroke, so that these portions .of'the pistons and cylinders the pistons and cylinders.

A still further object ofthe invention is the provision of a means for this-purpose which can'be readily attached to and formed with the pistons and with the engine block below the cylinders'of any known type of internal combustion engines without interfering with the remaining structure thereof.

It is a still further object to provide a lubricant system or means for this purpose which shall be simple in construction, cheap to manufacture and which will perform its purpose with ease, accuracy and efliciency.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the, accompanying drawings which form part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawings nor to the precise construction described and, therefore, such changes and modifications may be made therefrom as do not aifect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims. I In the drawings: Figure 1 is a sectional view through a porwill be efiectively lubricated to prevent undue wear and consequent scoring of such sides of tion of engine cylinder to illustrate the application of my improvement, the piston and other partsbeing also in section.

Figure 8 is a fragmentary sectional view through the type of engines having radially disposed cylinders such .as those employed upon aeroplanes and illustrating the application of my improvement thereon.

Figure 9 is a sectional view approximately i p on the line 9-9 of Fi ure 8, the piston connecting rod being. indicated by the dotted lines? 1 p Figure lOis a front elevation of the lubricant deflectors disclosed in Figures 8 and In Figures 1 and 2 of the drawings the numeral 1 designates a cylinder of .an. internal combustion engine, 2 the piston which reciprocates in the cylinder, 3 the'shaft, {l'the crank portion of the shaft and 5 the connecting, rod between the crank 45 and the piston 2. The piston 2 is of the ordinary construction but in carrying out myinvent-ion Ieither incal plane and has an'inner flange 7 that is tegral'lyfform, bolt, .or weld'therein-a metal *trough'lwhich is broadly indicated by the numeral 6." The trough, in the showing of the drawings is substantially semi-cylindri- Secured to the wall of the piston 2." Thef flange may be termed theibooly portion of the trough, the trough proper being somewhat spirally bentin plan to afford an upper porti0n8, whose top is openand a lower or downwardly directed portion 9 whose top may be closed. "The portion 8 has its end open,but

the end of the part 9 is closed and this part 9 delivers to an oil opening 10 in the piston 2.

The lower portion of the trough is arranged on the thrust side of the piston and likewise on the thrust side of the cylinder 1.

The crank 4 rotates in the direction of the arrow as disclosed by Figure l of the drawings. On theengine block,'directly below the cylinder 1 and at the said thrustsides of the cylinder and piston I fix in any desired or preferred manner the inner ends of director elements 11 and 12. Both of these elements are of the same construction, both being in the nature of channeled elements whose lower faces are open, as at 12, and whose front faces are arcuate and extended upwardly, as at 13. The top portions of the members 11 are also open, and the closed backs 14 are arranged angularly and are secured to the inner face of the engine block. From the arcuate front the sides of the lubricant deflectors are arched inwardly as at 15 to provide a clearance for the piston on the extreme down stroke thereof.

In operation the crank, traveling through the pockets therefor in the oil pan picks up and would ordinarily dash such oil against the wall indicated for distinction by the numera-l 16 of the cylinder 1. The piston rod travels between the deflector elements 11 and the oil from the-crank will be directed through the open bottoms of the said elements, against the inwardly curved front walls 12 thereof and be delivered against the second or thrust walls indicated for distinction by the numeral 17 in the cylinder 1. A portion of the lubricant will, of course, be splashed against the wall 16 and the lubricant 011 the wall 17 is received through the opening 10 in the piston upon the downward stroke thereof and directed into the downwardly rounded or curved trough in the said piston. Also a quantity of oil splashed by the cranks toward the wall 16 will be delivered into the open top of the trough and will be of the piston or otherwise effectively secured thereto slightly differs from that above de- 7 scribed. The trough comprises an upper downwardly inclined portion 19 which is widened and which has its top open. This face is also open.

ure 8 I have illustrated the improvement connected in any suitable manner in an engine provided with radial cylinders 22. The crank shaft for the pistons in the cylinder 22 turns in the direction of the arrow disclosed in c Figure 8 and the lubricant deflector elements, in this instance, have their outer walls concaved, as at 23 and the sides of their inner faces dished, as at 24, so that the lubricant splashing against the curved walls 23 will be directed toward the thrust wall of the cylinder 22.

Figure 9 illustrates the manner in which the piston connecting rod travels between the lubricant deflectors and Figure 10 illustrates in perspective the said deflectors.

The construction and advantages of my improvement will, it is thought, be understoodand appreciated by those skilled in the art to which such invention relates so that further description is not required.

Having described the invention, I claim l. Oil dcflectorsdesigned to be secured in an engine directly below the piston cylinder,

arranged in pairs to receive the piston connecting rod therebetween, each comprising a channeled member whose lower face is open and whose front face 1s curved and extended upwardly into the cylinder and whose upper 9 2. Oil deflectors designed to be securedin an engine directly below the piston cylinder, arranged in pairs to receive the piston connecting rod therebetween, each comprising a channeled member whose lower face is open;

and whose front face is curved and extended upwardly into the cylinder and whose upper face is also open and the side walls from the said openface of the deflector being arched inwardly to afford a clearance for the piston on the extremedown stroke of the piston.

In testimony whereof I affix my signature.
