OIL-DRAINING DEVICE FOR INTERNAL-COMBUSTION ENGINES.
Application filed October 8, 1920. Serial No. 415,687.
This invention relates to the removal of the from the crank casing of internal combustion engines. As is generally known it is necessary to remove from time to time I all the oil from the crank casing because the oi thickens gradually through impurities which admix with the same and in con-- sequence of decomposition through the action of the high temperature, so that even if a considerable quantity of fresh oil is admitted it is impossible to obtain a perfect circulation. With this object in view drains are arranged at the lowest point of the crank casing which are to be opened from time to time. Such oil drains possess however the inconvenience that when they become leaky all the oil can flow out, this low point of the crank casing being specially exposed to damages or to get foul. A
cock at this lowest point of the crank casing is besides diflicult to manipulate so that the draining of the oil is rather complicated.
' This invention avoids all these inconveniences owing to the use of an oil drain pump which removes the oil from the crank casing by suction, the ,suction orifice ofa hand pump being situated at the lowest point of the oil-collecting space of the crank casing.
The over-flow of the pump is preferably arranged in proximity of a feed tube so that the oil can be directly returned to the crank casing even without previous examination if required. In this manner it is possible to examine the oil in the crankcasing and to remove the same if it has become bad.
' In the accompanying drawing the inven tion is shown. The figure shows a cross section through a motor casing taken percrank shaft.
In the drawing: 1 designates the casing, here shown as having an upper closure. and a lower closure. the latter having no oil outlet in its walls, 2 the oil to be examined or removed, 3 a pump, 4 the suction orifice of the pump, 5 the over-flow oftho pump and 6 the oil inlet tube of the casin 1.
In the form of construction shown the oil can be returned in the simplest manner directly to the crank casing after, if necessary, the useless part of the same has been withdrawn.
1. The combination. with an engine crankcase having an upper closure provided with two adjacent apertures, of a pump extending removably through one of said apertures and having an outlet member arranged to discharge through the other of said apertures or into a receptacle disposed thereabove. 7
2. In combination with an engine crankcase having an oil inlet, a suction pump carried by the casing and having its suction orifice within the crank-case whereby the oil within'the crank-case can be withdrawn for examination or returned to the crankcase through the oil inlet.
3. An engine crank-case comprising an upper and a lower closure, the latter of which contains oil and the upper of which has an aperture; and a pump fitting in said aperture and constituting the only discharge 75 of the oil from the crank-case.
In testimony whereof I aflix my signature.
