LUBRIGATOR FOR EXPLOSION-ENGINES.

Specification of Letters Patent.

Patented Sept. 3,1912.

implication filed December 6, 1911. Serial No. 864,168.

To all whom it may concern.

Be it known that I, EARLI; W. GoonNow, a citizen of the United States, residing at Lansing, Michigan, have invented certain new and useful Improvements in Lubricators for Explosion-Emgines, of which the following is a specification.

This invention relates to improvements in lubricators for explosion engines.

In the operation of explosion engines, of

the so-called twin or duplex type having opposed cylinders, which are iubricated by the splash system, frequently an excess of lubricant is carried into one of the cylinders causing the cylinder, spark plug and other parts to foul, interfering with the efiiciency of the engine and requiring frequent cleaning.

It is the main object of my. invention to provide an improved lubricating means of the splash type for explosion engines having opposed cylinders in which the parts are so arranged that the cylinders do not receive an excess or undesirable amount of lubricant. v

Further objects. and objects relating to details of construction, will definitely appear from the detailed description to fol- 3, 1

I accomplish the oliljects of my invention by the devices and means described in the .part of this specification, in which:

Figure Iis a vertical longitudinal section taken on a line corresponding to line l 1 of Fig. II, one of the cylinders being shown in full lines. Fig; II is a transverse sec .tion taken on a. line corresponding to line '2-2 of Fig. I. Fig. III is an enlarged detail section taken on a line corresponding to line 3-'3 of Fig. I I, showing the mounting of theisplash finger 10. Fig. IV is adetail View taken on a line corresponding to line 4--4; of Fig. III.

In the drawing similar numerals of reference refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

leterring to the drawing, the cylinders 1- 1 are mounted on opposite sides of the crank casing .Z'to open into the same. The crank shaft 3. is provided with a pair of crank arms The pistons 5 are connected to these crank arms by the connecting rods 6 and 7. The crank shaft casing is provided with a depressed or well-like lubricant reservoir 8. This reservoir is on the side of the cylinder, the down stroke of whose connecting rod 6 is away from the cylinder. The bottom 9 of the outer side of the crank shaft casing is inclined to drain intov the reservoir. The connecting rod 6 is provided with a spiashjfinger 10 which, as the crank shaft revolves, dips into the lubricant throwing it against the wall of the crank shaft casing toward which it moves on the down stroke.

This finger is preferabl adjustably mount-' ed on the connecting ro bearing 11, the adjustment being effected by slotting the finger at 12 to receive the bolt 13. The object of the adjustment is to cause the finger to throw more or less lubricant, as desired. A shield 14: is provided {or the other cylinder. This shield projects from the wall of the crank shaft casing toward which the splash finger moves units down or splash stroke, the plate being disposed at the inner side of the reservoir to project toward the crank shaft. The shield is curved forwardly at 15. This permits it to project as much as possible Without" interfering with the crank shaft. By thus arranging the parts, the lubricant is splashedagainst the wall 16 and sufiiciently atomized and spattered about in the casing to effectively lubricate the parts, and, at the same time, the cylinders are protected so that they do not receive an excessive amount of the lubricant; that is, such an amount as interferes with their etliciency or would unduly. tout the cylinders.

I provide the reservoir with :1 having a T 18 at its outer end. The T 18 is provided with plugs 19 and 20. By remov ing the plug 19 the reservoir may be drained completely or by removing the plug 20 it may be drained to the proper level. The" reservoir may also be filled through the upper arm of'the T 18. The foul or used lubricant may be drawn off and the reservoir cleaned by flushing with kerosene or the like. p

I have ilh ed and; described my improvements in form in which I have embodied them for the market. I am aware, howei'er, that various modifications in structural details are ossible. I do not attempt to illustrate suc modifications herein as they will no doubt be readily understood by those skilled in this. art, but I desire to be understood. as' claiming my improvements specifically in the form illustrated, as well as broadly within the scope of the appended claims. a

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

1. In a lubricatin means for internal combustion engines aving a lurality of oppositely disposed cylinders, t e combina tion with the crank shaft thereof; of a crank easing into which said cylinders open pro vided with a lubricant reservoir on the side of the crank arm whose downstroke is away from its corresponding cylinder the bottom of the other side of the casing being adapted to drain into the reservoir; a splash finger for such crank arm; and a shield for the other cylinder project-in r from the wall of the crankcasin towar which said crank arm moves on its down stroke, said shield being disposed at the inner side of the reservolr. v

2. In a lubricating means for internal combustion engines having a plurality of oppositely disposed cylinders, t e combination with the crank shaft thereof; of a crank easing into which said cylinders open prcvided with a lubricant reservoir 'on the side of the crank arm whose down-stroke is away from its corresponding cylinder the bottom of the other side of the casing being adapted to drain into the reservoir; and a splash finger for such crank arm.

. 3. In a lubricatin means for internal combustion engines ving a plurality of cvlinders, the combination with the crank shaft thereof, of a crank casing provided with a lubricant reservoir on the side ol the crank arm whose downstroke is away from the cylinder in alinement therewith, such crank arm being adapted to splash the lubricant, the other side of the casing being adapted to drain; and a shield for the other cylinder projecting from the wall of the crank casing toward which said crank arm moves on its downstroke, said shield being disposed at the inner side of the reservoir.

4. In a lubricatin means for internal combustion engines aving a plurality of cylinders, the combination wit the crank s aft'thereof, of a crank casing rovided with a lubricant reservoir on the si e of the crank arm whose downstroke is away from the cylinder in alinement therewith, such crank arm being adapted to splash the lubricant, the other side of the casing being adapted to drain.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
