Application filed April 15, 1921. Serial No. 461,713.

To 'all fwwm t may concern:

Be it known that I, VICTOR W. PAG, a citizen of the United States, anda resident of the -city of New York, Kew Gardens, borough of Queens, in the county of Queens and State of New York, have invented anew and Improved Crank-Case Construction, of which the following is a full, clear, and exact description.

The present invention. relates to new and useful improvements in motors and it pertains particularly to a new and novel construction of crank cases therefor. Crank cases as commonly constructed have a drain voutlet disposed centrally of the bottom wall thereof and said outlet is generally closed by means of a screw plug. In constructions of this character lit is necessary to get beneath the motor to remove vthe screw plug in order that the crank case may be drained, which operation is attendant by various disadvantages.

lt is one of the objects of the present in-- vention to provide a crank case for motors in which the drain is not centrally disposed with respect;4 to the bottom wallthereof.

It is a further object of the invention to provide a new and novel means for closing the drain opening.

It is a further object of the invention to provide vcontrolling means lfor the drain opening which controlling means is capable of operation from above the motor rather than below the same as is the common practice.

With the above and other objects in view, reference is had to the accompanying drawings, in which.

Figure 1 is a transverse sectional view of a'\motor crank case showing the inven'- tion applied thereto;

Fig. 2 is a view in elevation plete closure member.

Referring more particularly to the drawings, the reference character 5 designates the crank case, the crank shaft and bearof the comings being designated by the reference characters 6 and 7, respectively. The reference character 8 designates the drain opening and said drain openin is positioned near one of the lower edges of t e crank casein a position where allof the contents of the crank case will drain towards said openin Depending from the lower wal of the crank case is an integral nipple or the like' `provide a seat 11.

9 provided with a central passage 10 and the upper end 'of said passage 10 is tapered to The reference character 15 designates a housing mounted interiorly of the crank case 5, and said housing is adapted to have its upper end closed by means of a screw-threaded plug or the like 16, which plug 16 is provided 4with amen'- tral opening or passage 17.

'The lower wall of the housing 15 is pro# vided with an opening or passage .18, and mounted for sliding movement in said passage or opening 18, is a plug 19. 4This plug has its lower end tapered as indicated by the reference character 2O and said tapered portion is adapted to seat or engage the tapered portionll of the passage 1() in order to close the drain opening 8 in the bottom wall of the crank case. provided with a reduced extension 21 and said reduced'extension has its upper end bifurcated as at 22. The reduced extensionv of the plug 19 .is slidably mounted in the passage or opening 17 of the screw-threaded member 16 in order to provide an upper guide for the plug 19. Interposed between the upper end of the plug 19 and the inner face of the screw-threaded member 16 and surrounding the lower portion of the reduced portion 12, is a coil spring 23, and said coil spring exerts a pressure down wardly suificient to maintain the tapered end of thel plug in engagement with the -seat 11 of the passage 104 in order to provide an e'ective closure for ing 8.

Pivotally secured in the bifurcated end of the reduced portion 21 as by means of a .bolt or the like 24, is a-rod 25, andsaid rod is provided upon its upper end with a handle 26. This rod is adapted.` to extend upwardly from the dcrank case of the. motor to the desired height, preferably beneath the hood of a motor vehicle. This handle 26 is provided upon one end with a hook'27, and said hook 27 is adapted to engage any one of a plurality of hooks 28 carried by a plate 29 suitably secured adjacent the motor.

The device operates Ain the following manner:

'Assuming that the crank case has the usual amountof oil therein, and it is desired to drain the same, the handle 26 is the drain open- 'grasped and the hook 27 is disengaged from that lug 28 with which it. is engaged. Upon The plug 19 is an upward pull on the handle 26, the tapered portion 20 of the plug 19 will be disengage from thefseat 11 of the drain opening, thus permitting the oilu to flow from the crank case'. lt is to be understood that this drain opening will be left open just so long as the hook portion 27 of the handle 26 is engaged with one of the lugs 28. When it is desired to close the drain opening, the hook 27 and the handle 26 are disengaged from -that lug with which they are engaged, and

under the iniuence of the spring 23the tapered portion 20 of the plug 19 will be moved into engagement With the seat 1l of the drain opening 8.

- From theforegoing it is apparent that i th present invention provides a new and novel controlling mechanism for openin and closing the drain of the crank case, an

at ,the same time, said operating mechanism is so positioned with respect to the motor crank case that it is not necessary to get n beneath the motor' to open the oranti; case d drain.

l claim:

lin a crank case having a disoliarge opening, a chamber formed on one of the side Walls of the crank case and positioned infv teriorly thereof, a tapered plug having a reduced extension, said tapered plug being slidably mounted in the bottom Wall oi said interior chamber, a coil spring surrounding the. reduced extension of the tapered plug and serving to maintain the tapered plug in position in the discharge opening of the crank ease, means exterior of the crank oase for operating said tapered plug to remove the samev from the drain opening oi the crank case, and means for maintaining said tapered plug out of engagement with said drain opening against the action of said coil spring.
