EDMUND W. FARR/IS, O33 FARGO, NORTH DAKOTA.

INTERNAL-COMBUSTION ENGINE.

Application filed June 2-9,

0 To all rte/1.0m 1'25 may concern.

Be it known that I, EDMUND W, F ARRIS, citizen of the United States, residing at Fargo, in the county of Cass and State of North Dakota, have invented certain new and useful Improvements in Internal-Combustion Engines, of which the following is a specification.

This invention relates to improvements in. internal combustion engines and moreparticularly to the lubricating means therefor.

The invention forming the subject matter of this application aims to provide a lubricating system for internal combustion engines having novel means for supplying. an increased quantity of oil to the several workingparts when the vehicle propelled by the engine is ascending a hill.

A further object of the invention is to provide a lubricating system for internal combustion engines having'ineans for automatically decreasing the supply of oil to the several working parts of the same when the vehicle propelled by the engine is descending a hill.

A further object of the invention is to provide a lubricating system for internal combustion engines which may be incorporated in the engine while the same is being built or at any time thereafter without materially altering the construction of the on gine.

A further object of the invention is to provide a lubricating system for internal combustion engines having eflicient means for collecting grit and other sediment which may be in the oil so that such grit or sedimentis prevented from working into the bearings and other working parts.

A further object of the invention is to provide a lubricating system for internal combustion engines which is entirely automatic in its operation. efficient and durable.

other objects and advantages of the invention will be apparent during the course ofthe following description. 1

'The invention forming the subject matter of this application is especially adapted for usein connection with Ford motors though it is obvious that the inventive idea may be carried out in motors of other types. However, in theFord motor, the principal objection to the lubricating system is the fact that no means is provided for increasing the supply of oil when the motor is propelling a vehicle uphill and, therefore, the hearings in the forward portion of the motor soon become worn. On the other hand, when the forward portion of the motor is inclined upwardly due to the ascension of the vehicle. the oil in the forward. portion of the motor gravitates to the rear of the motor, thereby leaving the forward bearings without the proper supply of oil. This invention overcomes the above diflieulty since it automatically increases the supply of oil to the forward portion of the crank case when the vehicle is ascending a hill and also since it conveys the oil rearwardly without lubricating the forward bearings when the motor is descending a hill thereby preventing the forward cylinders from fouling due to an excessive supply of oil.

In the drawings, wherein for the pure to thecranlr case through the mediurn oili- 3 ofli-he' oil, pan, the-oil 'graduially moves rear pose of illustration is shown a preferred embodiment of the invention, the numeral 10 generally designates an internal combustion the receptacle 28. l/Vith the motor posiengine composed, as usual, of a crank case tioned as above described, the oil within the. 11 upon which is mounted a plurality'otreceptacle"28 flows over the upper end of the flywheel to the neck 24o'f the oil conveyer26 and from" the oil conveyer 26 "into cylinders 12.

As set forth above, it is objectionable to allow the oil. to flow entirely to the rear of the motor when the motor is under an. increased strain and, therefore, the forwardly extending side arms 51 of the ballles 5O serve as a means vtor confining the oil in the several transversely extending troughs when the motor is inclined rearwardly and in operation.

The oil pan is also provided with a plurality oi U-shaped battles 54: arranged forwardly oi the several troughs 14 and provided with rearwardly extending arms 56 which, as clearly illustrated in Figure 7, are arranged inwardly of and in spaced relation to the tern'iinal portions of the side arms 51 so as to provide an oil passage between the adjacent portions of the arms 51 and 56, The oil passages thus formed between the arms 51 and 56 allow the oil upon flowing rearwardly to enter the troughs 14 and thereby be trapped by the baffles 50.

\Vhen the motor is inclined downwardly toward its forward end as the result of the vehicle descending a hill, the natural tendency is under ordinary circumstances for the oil'to flow to the forward portion of the crank case and thereby cause the forward cylinder or cylinders to foul. However, the bailles 534 with the rearwardly. extending arms 56 serve as an e'tiicient means for preventing the oil -from flowing to the forward portion of the motor in excessive quantities. The haliles 50 and 54 may be 'fOliTlGCl integral with the oil pan during the manufac ture and. iii desired. the intermediate bai'lles may have their connecting portions formed from one piece as illustrated.

'l. he improved. oil regulator operates most eiliciently on a level motor and as the forward portion of a Ford motor is in some cases lower than the rear portion of the nmlior when mounted on a Frame l. have provided a simple means whereby the forward portion ot the motor may be elevated without altering the construction oi any of the parts. As illustrated in Figure 9, the forward portion 60 of the crank case 11 is provided with a collar 62 which rotatably receives the shaft 01' a hand crank 64. llnder ordinary conditions and as the n1otor is now mounted upon the frame, the collar rests within a semi-circular recess 66 in a head block. 63 which latter is mounted upon the cross spring 70 and secured to the same through the medium of ll-shaped bolts 72. The forward portion oi the crank case may be slightly elevated by arranging a semi-circular bearing '74 in the semi-circular recess 66 directly beneath the collar 62. A. cap '76 of semi-circular formation is extended over the collar 62 and is provided. with apertured cars 78 alined with the aper tured ears 80 of the bearing 7 1 torthe reception of cap bolts 82 having threaded engagement with the head block 68. The ap plication of the semi-circular bearing memher 7 1 elevates the forward portion. of the motor so that the same is positioned hori zontally. The semi-circular hearing may be of a thickness suilicient to level the motor and may be applied without any elaborate dismantling oil? the motor. H

lVith reiierence to the foregoing descriptiou, taken in connection with the accompanyiug drawings, it will be observed that an internal combustion engine having the improved lubricating system will operate with an increased degree of eliiciency since an increased supply of oil is provided when the motor is under strain and since the supply of oil is automatically decreased when the strain on the motor is removed. Attention is invited to the fact that any sediment which may be in the oil will remain inthe lower portion of the receptacle 28 and will not be allowed to flow either through the forward passage 38 or the rearward pas sage 33. i

it is to be understood that the form of the invention herewith shown and described is to be taken as a preferred example of the same and that such minor changes in arrangement and construction of parts may be made as will remain within the spirit of the invention and the scope of what is claimed.

Having thus described the invention, what is claimed as new is:

1. The combiiuition with an internal coup bustion engine having means :lor discharging oil at the forward portion of the same, oi? an oil receiving member arranged at the forward portion of the crank case of the engine and provided with-discharge passages, and oil coi'iveyers having communication with said passages and extending in opposite directions from the receptacle.

2. The combination with an internal combustion engine having a crank case, of an oil receiving receptacle arranged in said crank case and provided with a pair of partitions thereby forming a pair of passages, and pipes extending :l orwardly and rearwardly from said receptacle and having); communication with said pass ges. i

3. The combination with an internal (5011b luistion engine provided with a crank case, of an. oil receiving receptacle arranged within said crank case and provided with forward and rearward partitions thereby forming forward and rearward passages, said partitions terminating below the horizontal top edge of said receptacle, a rearwardly extending pipe having communication with said forward passage, and a forwardly extending pipe having communication with said rearward passage. In testimony whereof I a'fiix my signature.
