OILING SYSTEM FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Apr. 9, 1912.

Application filed July 29, 1911. Serial No. 341,299.

a novel construction, particularly applicable to the crank case of an engine such as those of the type commonly used on motor vehiclesl, for the purpose of automatically providing an increased supply of oil for lubricating the various parts when the engine is ,inclined as in ascending a grade; the increased supply being proportional to the amount of such inclination and the arrangen'l ent'being such that when the engine again assumes a levek position the amount of oil in active circulation is shortly reduced to normal.

' It is further desired that the construction shall be such that when the front end of the engine is downwardly inclined, oil shall be collected in one or more supplementary reservoirs and thereafter be at once placed in active circulation when the engine returns to a level osition so that there is no danger of a fallure in the delivery of a proper amount of oil to the various parts requiring lubrication.

These objects and other advantageous ends I secure as hereinafter set forth, reference bein had to the accompanying drawings, in w ich;

Figure 1, is a vertical section of the lower portion of the crank case of an engine illustrating my invention as applied thereto;

. Fig. 2, is a side'elevation of the crank case shown in Fig. 1, illustrating the piping for distributing the voil to the supplementary reservoirs, and Figs. 3 and 4 are vertical sections, respectively taken on the lines a-a, and b--b, Fig. 1.

In the above drawings 1 represents acasting forming the lower portion of an engine crank case and 2 is the crank shaft, in this instance provided with four cranks to which are respectively connected rods 3, 4, 5-,.and 6. -The lower portion of the crank case is in the form of a main reservoir 7 wHose' bottom slopes from its front end 1 toward its rear end and has connected adjacent said latter end a pump 8 designed to draw lubricant from the deepest portion of said reservo1r.

Either integral with the structure 1 or independent thereof are four supplementary reservoirs 9, 10, 11, and 12, inthe present instance in the form of narrow containers of approximately crescent shaped section and extending transversely of the main casting 1, respectively under or in the plane of oscillation of, the various connecting rods 86. Each of these supplementary reser voirs has an opening 13 at its forward side to permit of the overflow of lubricant into the main reservoir 7, while at its rear edge there is provided a structure formed in'the present instance of a ledge 14 and a transversely extending artition 15 constituting a pocket, which w en the forward end of the crank case is raised, serves to catch and retain a certain amount of lubricant.

In addition, at the forward part of each of the supplementary reservoirs is a transversely extending ledge 16 and a transverse partitlon 17 which in some cases is provided b the partition 15 and in other cases is distinct therefrom, as indicated at 17. There is then formed a second pocket designed to catch and retain lubricant splashed up by the connecting rod when the forward end of the crank case is depressed.

Each of the various partitions 15 or 17 is of a definite height so as to permit of 'the overflow of oil after a certain amount has accumulated; there being in the case of the rearmost partition an opening 18 to permit of thisoverflow.

Bet-Ween the-ledges 16 and 14 of the two supplementary reservoirs 9 and 10 there is a single transverse partition, although in the case of the two supplementary reservoirs 10 and 11 two partitions 15 and 17 are provided, wit-h an opening between them; it bein' in most instances immaterial as to whici construction is adopted.

' For supplying oil to the various supplement'ary reservoirs, the delivery end of the Under operating conditions, with the crank case of the engine in a substantially horizontal position, oil is drawn by the pump from the main reservoir 7 of the crank case and is forced through the pipes 18, 19, and 20 and thence to the various reservoirs 9, 10, 11 and 12.

By what is known as splash lubrication, the various connecting rods deliver this oil to the crank pins and other parts requiring lubricant, the surplus oil escaping from the reservoirs to the main reservoir through the overflow openings 13. If now the front end of the crank case be raised, as when the vehicle on which the engine is mounted is ascending a grade, the oil, instead of escaping through the overflow openin s 13, c0 lects in greater quantity within t e various supplementary reservoirs 9 and 10, etc., and also is retained b the pockets formed by the partitions 15 an ledges 14.

As a consequence there is provided for each connect-ingrod a body of oil in excessof that normally in active circulation and which in amount is proportional to the inclination -of the englne and hence in some degree likewise proportional to the increased amount of work put upon said engine by reason of the grade. There is thus applied to the parts requiring lubrication a sufiicient amount of oil to maintain them in proper Working condition and as soon as the engine returns to its horizontal position, the surplus oil previously collected is at once returned to the main reservoir throu h the overflow openings 13 where it is not 111 circulation. If, on the other hand, the forward end of the crank case be depressed, as when the engine is descending a grade, the supplementary reservoirs would temporarily contain but relatively small amounts of oil and when the engine returns to the horizontal position it might be compelled to o erate for an appreciable time without su cient lubricant for the various parts. By my construction, however, this condition is avoided, since as soon as the forward end of the engine is depressed, lubricant .collects in the pockets formed by the ledges 16 and the partitions 15 or 17 as the case may be, so that as soon as normal conditions again exist, a body of oil is at once delivered to each of the supplementary reservoirs from these pockets so that the connecting rods and their associated parts receive ample lubrication.

It'is obvious that while my system is primarily intended for engines used on motor vehicles, it is notnecessarily confined to engines of this type, since it may be advantageously employed on engines or other machines whose position varies sufficiently to render it operative.

I claim 1. The combination of a crank case having a main oil reservoir; a series of containers forming supplementary reservoirs and each having an overflow outlet at its forward side; a pocket for each supplementary reservoir placed to receive and hold oil when the forward end of the crank case is raised; with means for causing oil to flow from the main reservoir to the supplementary reservoirs.
