CRANK CASE Filed March 20. 1930 2 Sheets-Sheet 2 4- Inuenlor A llorney Patented Mar. 1, 1932 UNITED STATES 03mins- A. BUSCH, or .iorlmn nnmois '5 7 I cnamrcasn Application mm March 20; i930; eaano gia character, embodying means to facilitate the separation of water and other foreignm'atter from the lubricating oil and further to drain said water and other foreign matter from the crank case without the necessity of removing the oil therefrom, thus avoiding a considerable waste of lubricating oil which takes place at present.
Other objects of the invention are to provide a crank case of the aforementioned character embodying means for accomplishing the vpurpose heretofore set forth which will be simple in construction, strong, durable, efficient in its use and which may be manufactured at low cost.
All of the foregoing and still further obao jects and advantages of the invention may become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and
wherein Figure 1 is a view in side elevation showing a crank case constructed in accordance with this invention mounted in position on the engine.
Figure 2 is a view in top plan showing the valve which is disposed over the sump.
Figure 3 is a vertical longitudinal section- .11 view taken substantially on the line 33 of Figure 2.
Figure 4 is a detail viewin perspective of the valve.
Figure 5 is a fragmentary sectional view showing the drain plug in the sump.
Referring to the drawings in detail, it
will be seen that'the reference numeral 1 designates the engine and 2 is the crank case which is bolted tosaid engine in the usual manner, ias'at 3. In the comparatively deep 'rear'endportio ofacrank case, the bottom, wallet thereof is formed to provide, a sump designated generally by the reference numeral '5 and having-inclined sidewalls 6 and a flat horizontally disposed bottom wall 7 having'an upstanding integrally'formed boss 8 "disposed 'centrallytherein. The inner periphery 'ofthe side walls f the sump is beveled atgitsupper'end to provide a valve seat 9 upon which 'is engageable a vertically shiftable valve 10 rigidly mounted on the 55 upper end of a threaded stem 11 through the medium of the nut 12 between which the valve 10 is disposed. The stem 11 is threaded for vertical movement through a threaded opening provided therefor in the boss 8 and 70 the bottom wall 7 of the sump and a polygonalhead 13 is provided on the lower end of' the stem to receive an actuating tool such as a wrench. A packing gasket 14 is disposed on the stem 11 between the head 13 and .7 the bottom wall 7 of the sump to prevent leakage between the stem 11 and the boss and said bottom wall through the opening in which said stem extends.
Adjacent one side, the bottom wall 7 isgo further provided with an integral boss 15 and a threaded opening extends through said boss and the bottom wall for threadedly receiving the removable plug 16 having the polygonal head 13 on its outer end for receiving an actu 85, ating tool and a flange l8 engageable with the free end of the boss 15. The removable plug 16, constitutes means for draining the sump 5 when it is so desired.
In use, the valve 10 is normally maintained 00 disengaged from the seat 9 as illustrated in Figure 3 of the drawings and when in this position any water or other foreign matter may be present in the lubricating oil in the crank case will gravitate into the sump." This water orother foreign matter may then be drained from the sump without removing the oil from the crank case by simply actuating the stem 11 in a manner to seat the valve 10 tightly on the valve seat 9 and the ment through the opening having a wrench receiving head on its outer end, avalve disc .rlgidly mounted on the inner end of the head drain plug 16 is then removed to empty the sump 5. It will thus be seen that the oil will be retained in the crank case.
It is believed that the many advantages of a crank case in accordance with this invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction may be had which will fall Within the scope of the invention as claimed.
What is claimed is A crank case of the character described comprising a bottom wall having a sump formed therein, saidsump open at its top for communication with the'cranke case, a valve seat formed on the upper end of the sump,
said sump being provided with a threaded opening formed centrally in its bottom Wall, a threaded stem mounted for vertical moveand engageable on the valve seat in a manner to close the sump when the stem is turned to project said stem and-a removable drain plug in the bottom wall of the sump.
