OIL DRAIN.

Application filed July 8, 1927. Serial No. 204,350.

' This invention relates to improvements in oil drains which embodiesamong other ch aracteristics a construction permitting drains for reservoirs to be controlled at remote points.

Another object of the invention comprehends a depth gage operable in conjunction with theoil drain. a

A further object of the invention contemplates a handle member for the oil drain.

More specifically stated the oil drain is adapted to receive the gage.

Said drain is furthermore provided with openings to permit the'contents of the reservoir to seek its level therein whereby the oil level of the reservoir may be readily determined upon the withdrawal ofithe gage from. the drain.

With the above and other objects in view, the invention further consists of the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawing and. pointed out in the appended claim.

In the drawing: I

Figure 1 is a transverse section taken through the crank case of an internal combustion engine and illustrating the arrange.-

I ment and application of the invention there- 7 30 with. I

Figure 2 is a longitudinal sectional view of the invention per se. Y Figure 3 is a sectional 33 of Figure 1'.

Referring to the drawing in detail, wherein like characters of reference denote corresponding parts, the reference character 10 indicates the crank case of an internal comview taken on line bustion engine having an oil pan 11, the above being of the usual construction as embodied in the crank cases of motors of the character described.

It is generally known in the construction of the particular type of motor,aforementioned, that the most effective and reliable oil gage is that of a thin strip extended -with- -in the crank' case, the oil level within the crank case will be indicated upon the strip.

In carrying out the invention" it is mycardinal purpose to utilize the aforementioned tvpe of gage 12 and to combine therewith a housing, member therefor such as indicated at 13, closed uponone end and provided with a threaded extension 14 adapted for engage ment within a drain opening 15 within the bottom of the pan 11 and disposed in alignment with the opening in the crank case. Said housing 13 is provided with handle portions 16 to permit the same to be easily rotated in either direction. When the threaded extension 14 is removed from the opening 15 the contents of the .crank case will be drained, thereby obviating the usual necessity of crawling beneath a motor vehicle and loosen-- ing a cap screw to accomplish this purpose which often provesdisastrous in the event that the oil finds its way up the sleeve. The gage 12 is provided with a knob 17 upon the outer extremity thereof and a tapered portion 18 disposed within a seat 19 having communication with the bore of the housing 13.

An enlargedportion 20'provided adjacent the outer end of the housing is adapted to strengthen the same at the point wherein the same will more frequently rub or chafe against the walls of the opening in the crank case. The lower portion of the housing is furthermore provided with a multiplicity of openings 21 having communication with the bore thereof in order that contents of the pan 11 may seek its level within the housing. The gage 12 when removed from the housing will indicate the oil level within the crank case. It is thus to be noted that essential and effective means have been combined to produce an oil drain capable of being operated at a remote point from the oil drain in the crank case and of the gage operable in conjunction therewith. The construction involved will permit the same to be manufactured at small cost and hence appear upon different makes of automobiles as a decided improvement and sales getter. j

The invention vis susceptible ef various changes in its form, proportions 'and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.

Having thus described the invention, what is claimed is! An oil drain and gauge for use within the crank case of an internal combustion engine comprising a tubular member having perforations in the periphery thereof adjacent one end, said tubular member having a closed end adjacent said perforations having-screw threads on the periphery thereof whereby said end may be fitted into the drain opening" in the crank case, said tubular member having an enlarged portion on the periphery thereof at the endthereo'f opposite said end having said enlarged end may be extended through lar member having a conical portion on the an opening in the upper portion of said crank outwardly disposed end thereof whereby said case, a handle fitted at the outer end of said conical portion may be seated on said valve 10 enlarged portion, said tubular member havseat to retain said gauge in said tubular mem- 6 ing a tapered portion on the inner periphery ber.
