LUBRICATING SYSTEM FOR MOTORS.

Specification of Letters Patent.

Patented July 21, 1914.

Application filed April 21, 1913. Serial No. 762,527.

To all whom it may concern:

Be it known that I, \VALTER L. MARK, a citizen of the-United States of America, residing at Flint, in the county of Genesee and State of'Michigan, have lnvented certain new and useful Improvements in Lubricating Systems for Motors, of which the following is a specification, reference being had therein to the accompanying drawings.

In the operation of automobiles, motor boats and the like, wherein the motor is liable to assume different inclined ositions owing to the movement of the ve icle or boat, it is desirable for the feed pump of the lubrica-ting system, if the latter be of the type wherein the circulation system includesthe engine base for trapping and returning the oil to the pump, that the oil be maintained at sufficient depth around the pump to always supply the latter regardless of the position of the motor.

This invention relates to a lubricating system for motors of automobiles, boats and the like wherein provision ismade for maintain ing a supply of lubricant for a pump included in the system, regardless of the angle of inclination of the motor or its position under ordinary working condition.

The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a plan view, partially broken away of the base of a motor, a feed pump and a gage tank that embody features of the invention; Fig. 2 is a view, partially in side elevation and partially broken away and in sect-ion of the base, tank and pump; Fig. 3 is a view in detail of a return check valve; Fig. 4 is a. view taken on orabout line IV IV of Fig. 1; Fig. 5 is a view taken in section on or about line VV of Fig. 1; Fig. 6 is a View in end clevation of Fig. 1; Fig. 7 is an enlarged View,

- partially in longitudinal section and partially in elevation of a feed pump and driving mechanism therefor; Fig. 8 is a view in detail of the pump; and Fig. 9 is a view taken on or about line IXIX of Fig. 7

As herein shown in preferred form, an engine base 1 suitably ribbed and flanged to combine strength and lightness is provided at intervals with cross walls. These are through the pairs of cross walls.

grooved, hollow or disposed in pairs, and

form supports for the crank shaft bearings between which the cranks 0f the engine play.

A feed duct extends longitudinally of the base in substantially parallel relation to the upper, normally horizontal face thereof and In preferred form, the duct is formed by a pipe indicated at 2, Wa is cast into the base when the latter is housed and is provided with a forward discharge aperture 3 that opens into the groove, hollow or space between the forward cross walls 4, another opening 5 that discharges into the space between another pair of cross walls 6, an aperture 7 be tween the cross Walls 8, and an aperture 9 between the cross walls 10. The base, which is substantially semi-circular in cross section, slopes downwardly from its forward end to its rear compartment in which the fly wheel turns. A combined gage reservoir and tank is seated on the dash or other convenient observation spot of the vehicle or boat on which the motor is mounted and communicates with an inlet 11 of the pipe 2 through a suitable pipe 12 or the like. the reservoir being adapted to supply the inlet by gravity. In preferred form the tank comprised a base 13 on which a bell jar '14 of glass or transparent material is secured as by a clamping rod that may also hold a filling cap 16 in place. As one means of making connections between the pipe 12 and the inlet of the pipe 2, the pipe may have a flanged end .17 secured by a collar 18 on the nipple 19 of a fitting 20 detachably held against the side of the casing of the. base by set screws 21 or the like.

A pump casing 22 is removably secured in the opening in the base near the lowest point thereof by cap screws 23 or the like. Aforamin'ous cage 24 that acts as a screen to exclude dirt and like foreign substances is formed on the casing aroundan inlet resists endwise movement and that corresponds to an enlarged portion 36 of the journal 29, the spring 28 being in compression between the heads. A suitably disposed oil duct 37 sufficiently lubricates the bearing of the journal 29.

To prevent the escape of the oil from the space around the pump cage when the motor is tilted forwardly, and the oil approaches the level indicated by the broken line 38 of Fig. 2, (suitable openings indicated at 39, in the forward cross walls,permitting this,) a swinging check valve is placed in an opening through the base of the walls 8, 8, this opening being so disposed as to normally allow the oil to fiow backwardly toward the pump chamber. Preferably the check valve consists of a closure 39 which hangs on a pivot pin 40 passing through a lug 41 extending from the closure, the parts being so disposed that the closure seats itself when the base is tilted forward slightly but opens to allow the backward flow of oil when the level thereof ahead of the walls 8, 8 comes higher than that of the lubricant accumulated in the chamber containing the pump gage. As a result of this construction any lubricant finding its way into the spaces between the bearing walls through the longitudinal and normally horizontal duct or pipe, returns down the sloping wall of the base and collects in the chamber around the gage of the pump and afi'ords adequate supply to the latter under ordinary working conditions. If the motor is tilted forwardly, the check valve prevents the corresponding movement of the oil and traps it so that it is retained in the base around and over the pump inlet.

Obviously, changes in the details of construction may be made without departing from the spirit of my invention and I do not care to limit myself to any particular form or arrangement of parts.
