" TTED STAT ares LUBRICATING SYSTEM FOR ENGINES.

Specification of Letters Patent.

Patented Feb. 13, 1912.

Application filed October 21, 1911. Serial No. 655,837.

To all whom it may concern Be it known that I, BENJIMAN H. TURN- AGE, a citizen of the United States, residing at- Society Hill, in the county of Darlington and State of South Carolina, have invented certain new and useful Improvements in Lubricating Systems for Engines, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to new and useful improvements in lubricating systems for engines and more particularly to an automatic oiler for the crank case thereof, the primary object of the invention being to 'provide such a system wherein there will be a constant circulation of the lubricant when the engine is in operation and at all times will provide a suflicient amount of oil to lubricate the parts in the crank case,

A further object of the invention resides in providing a system wherein the oil is fed by gravity to the crank case, and a still further object resides in providing a means for drawing the oil from the crank case when the engine is in motion.

Still another object of the invention resides in providing an auxiliary tank into which the oil from the crank case is drawn,

said tank being also in communication with :the supply pipe extending from the resertank to flow to the crank case when said float valve is moved to its efiective position.

A still further object resides in providing a device which is simple and durable in construction, inexpensive to manufacture, and thoroughly efficient and useful in operation. I With these and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawing forming a part of this application, the figure is a side elevation partly in section of my improved system.

In carrying out my invention, I shall refer to the drawing in which similar reference characters designate. corresponding parts throughout the several views and in which- 1 indicates an oil supply tankor reservoir which, when used on an automobile, is adapted to be positioned either on the rear of the machine or below the seat thereof, as desired, from which tank extends a supply conduit 2, and an auxiliary tank 3 is also provided to which said conduit leads, but does not directly communicate therewith. The tank 3 has threaded on the upper end thereof, a cap or closure 4, and disposed in said tank, is a float or the like 5 pivotally carried on the one end of an arm 6 which, in turn, is pivotally carried on the one end of a balancing arm or lever 7. This balancing arm 7 is pivoted, as shown at 8, in one side of the tank 3 having a portion thereof extending within said tank proper, while a portion thereof extends therebeyond, and the end of the latter portion has pivotally connected thereto, an arm 9, the purpose of which will be hereinafter and more particularly described. The arm 9 and that portion of the arm 7 which extends beyond the side of the tank 3, is inclosed in a casing or the like 10 formed on the side of the tank 3, into the lower end of which extends the conduit 2, and the lower end of said arm 9 carries thereon, a valve 11 which is adapted to be disposed in a seat 12 at the point where the conduit 2 leads to said casing 10, whereby it will be seen that the flow of oil from the tank 1 to the casing 10, may be cut off at certain times. This casing 10 has also leading to the lower end thereof immediately adjacent the point to which the conduit 2 leads, an additional. pipe or conduit 13 which extends upwardly to a crank case 14 of an engine 15 and this pipe 13 also communicates directly with the tank 3 through the opening or passage-way 16, the purpose of which will be hereinafter and more particularly described. The tank 3, itself, communicates with the casing 10 above the point where the float reaches its maximum point, as shown at 17 the purpose of which will also be hereinafter and more particularly described, and communicating with said tank 3 immediately adj aecnt the bottom thereof, is a casing 18, within which is mounted a rotary motor or pump 19, said casing also having extending therefrom, a conduit 20 which extends to and communicates with said crank case 14:. This rotary 'pump or motor l9 is preferably operated from the engine 15 in any desired manner,

but, of course, may be otherwise operated, if desired, and it must also be stated that the casing It) is provided at the upper end thereof. with,an opening 21- for which there is provided a closure 22, whereby in case of necessity, for any reason, whatsoever, entrance may be had to said casing 10.

In operation, when the'reservoir' is filled with oil, said oil is adapted to feed by graverably connected with said engine, is set inmotion which will draw the oil from the crank case 14 through the conduit 20 into the auxiliary or float tank 3, and as the oil rises in said tank 3, the float 5 will rise therewith and when reaching a predetermined point, will cause the valve 11 to be disposed effectively in the seat 12 and there by prevent the further flow of oil-from the tank 1. When the float 5 reaches this'point, however, the opening 16 in the tank 3 leading to said pipe 13, will be below the level of the oil in said tank, which will permit saidoil toflow through said conduitld back to the crank case 14. This will, of course, allow the float to descend slightly which will permit of the valve 11 being opened, whereby the flow of oil from the tank 1 will again be permitted to flow directly to the crankcase 14, and in this manner, the oil is kept constantly flowing to the crank case and is set in circulation by the pump 19 as long as said engine is in operation. Should at any time the flow of oil into the tank 3 from the crank case 14: through the conduit 20-become so great as to overflow the float 5, said oil may be permitted to make its exit through the opening 17 into the casing 10, where it will pass to the conduit 13 and again be conducted to the crank case, and in this manner, there will be absolutely no chance for overflow and at the same time, a constant flow, of oil will be conducted to the operating parts in said crank case When the engine is not in operation, however, so

that the pump 19 will also not be inoperation, the oil in the crank case and the tank 3 will seek equal levels, which level will cause the float 5 to' reach its maximum height and thereby close the valve 11 and prevent the unnecessary flow of oil from the tank 1, and thus it will be seen that the parts in the crank case may be; lubricated even when the engine is not in operation.

From the foregoing, it will be seen that 1 have provided an improved oiling system for the crank case of an engine, wherein the same will be effective whether said engine It will further be 1 fie will be a constant c1rculat1on of the 011 when is in operation or not. seen that this system is one in which there the engine is in operation. It- 'will further be seen that'I have provided an auxiliary tank havingindirect communication with the supply pipe between the crank case and the main reservoir, which tank has means therein for the control of oil from the main reservoirto the tank.- Furthermore, it will be seen that I have provided means for the drawing of the oil from the crank case to this'tank, which oil, drawn within said tank, is adapted to indirectly control the flow of oil from the main reservoir to said crank,

case. the apparatus in this device is simple and durable in construction, the same is extremely efficient and useful in operation.

What I claim is 1. In a lubricating apparatus, the combination with an oil reservoir, and a conduit leading therefrom; of an auxiliary tank with which said conduit communicates, a p y point a acent the entrancev of the conduit thereto, to a housing-adapted to receive the oil from the reservoir, a return pipe entering said tank, and a float valve in said tank operating in connection with the aforesaid conduit at its entrance to the tank. 2. In a lubricatingappara-tus, the'combination with an oil reservoir, and a housing (pipe leading from said tank, at a i It will still further be seen that while" ice to which the oil in said reservoir is adapted to be onducted; of an auxiliary tank, a conv duit leading from the reservoir to said tank, a supply pipe extending from the tank to said housing, the entrance of said pipe to the tank being adjacent the entrance of the conduit thereto, a return pipe between said case and tank, a rotary pump mounted with: in said return pipe, at float within said tank,

and avalveoperated by said float to open andkclose the entrance of said conduit to the tan a 4. In a lubricating system of the class described, the combination with the crank case of an engine; of an oil reservoir, an auxiliary tank, said tank having a casing formed on one side thereof, a conduit leading from said reservoir to said casing, a float-operated valve at the entrance of said conduit to said casing, an additional conduit extending from said casing to the crank case, said latter conduit also having direct communication with the tank, communicating means be- .tween the lower portions of said crank case and tank, and a pump disposed in said communicating means.

5. In a lubricating system of the class described, the combination with the crank case of an engine; of an oil reservoir, an auxiliary tank, said tank being provided with a casing in one side thereof having communication with said tank, conduit leading from said reservoir to said casing, a valve seated at the entrance of said conduit to said casing, a float disposed in said tank operating said valve, an additional conduit lead ing from said casing to the crank case, said latter conduit also having communication with said tank, and a pump adapted to draw the oil from the crank case to said tank.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses. BENJMAN H. TURNAGE. Witnesses:
