Abstract

ABSTRACT OF THE DISCLOSURE
This device consists primarily of an oil pan for com-bustion engines, which comprises an improved crank case oil pan, comprising in combination, a plurality of six interfitting sections, and including an end section at each end and a pair of wedge-shaped sections therebetween, each said section including a flange having openings therethrough for receiving mounting bolts to fasten said sections to an underside of an engine block, said bolts extending through a gasket fitted between said engine block and said oil pan, one end of said oil pan being downwardly relatively deep while an opposite end thereof is downwardly shallow, a vertical wall forming a shoulder between said deep and said shallow ends, said vertical wall extending across said wedge-shaped sections, each said section additionally including an outwardly turned flange along all edges that abut with mating-like flanges of an adjacent said section, bolt openings through said flanges receiving mounting bolts for securing said sections together, and said sections each being in-dependently removable from said engine block without need of removal of adjacent said sections.

Description

106~740 This invention relates to internal combustion engines, and more particularly to a crank case oil pan. According to the invention, there is provided an improved crank case oil pan, comprising in combination, a plurality of six interfitting sections, and including an end section at each end and a pair of wedge-shaped sections therebetween, each said section including a flange having openings therethrough for receiving mounting bolts to fasten said sec-tions to an underside of an engine block, said bolts extending through a gasket fitted between said engine block and said oil pan, one end of said oil pan being downwardly relatively deep while an opposite end thereof is downwardly shallow, a vertical wall forming a shoulder between said deep and said shallow ends, said vertical wall extending across said wedge-shaped sections, each said section additionally including an outwardly turned flange along all edges that abut with mating-like flanges of an adjacent said section, bolt openings through said flanges receiving mounting bolts for securing said sections to-gether, and said sections each being independently removable from said engine block without need of removal of adjacent said sections.
In the past it has been a difficulty that it was usually necessary to raise the engine in a vehicle in order to remove the oil pan. Designs to alleviate this problem have generally been unsatisfactory. The present in-v~ation provides an improved sectional oil pan which serves to overcome-the difficulty by allowing removal without raising the engine.
It is therefore the principal object of this invention to provide an oil pan which will be composed of two sections.
Another object of this invention is to provide an oil pan which will be of two piece construction, so as to eliminate the former necessity of raising the vehicle's engine, thus saving time and labor.
A further object of this invention is to provide an oil pan of the type described, which will have overlapping edges on the two sections or abutting edges, which will be fastened together by suitable fasteners.
Other objects of the invention are to provide an oil pan which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.

,........................ 1 --"'l'' These and other ob~ects will be readily evident upon a study of ,he following specification and the accompanying drawings, wherein:
FIGURE 1 is a side view of the present invention shown partly broken away and separated from the engine block;
FIGURE 2 is a top plan view of the invention;
FIGURE 3 is an enlarged cross-sectional view taken along the line 3-3 of Figure 2;
FIGURE 4 is similar to Figure 3, but shows a modified form of joining the two members of the invention;
FIGURE 5 illustrates a modified crank case oil pan according to the present invention.
According to this invention, a crank case oil pan 10 issh~wn to include one hollow section 11 which mateingly engages with a second section 12, each of the sections 11 and 12, having a mating flange 13 with spaced apart opening 14 for receiving suitable fasteners 15 for securing pan 10 - la -iO60740 to engine block lOa.
As will be seen more readily in Figure 3 of the drawing, a gasket 16 is secured between the overlapping edges of sections 11 and 12 of pan 10 so as to provide an effective seal when oil pan 10 is secured to the engine block lOa.
Referring now particularly to Figure 1 of the drawing, it will be seen that a modified separation point for sections 11 and 12, is indicated by the numerical characters 17, which may be the preferred joining point for some automotive engines.
Referring now to Figure 4 of the drawing, a modified joining means is indicated by a section lla abutting with section 12a, the arrangement including a gasket 16a therebetween.
In Figure 5 of the drawings, there is shown a modified design of crank case oil pan 20 which differs from the crank case oil pan 10 of the preceding Figure by being made up of more than only two sections. The oil pan 20 as shown includes opposite end sections 21 with intermediate sections 22 therebetween. This form of the invention preferrably employs the flange type construction of Figure 4 in order that the intermediate sections 22 can be readily removed alone in case the end sections 21 are preferred to not be removed. Also it is to be noted that each of the intermediate sections 22 are of wedge shape so that they will readily slip out from the space 23 after the fasteners 15 are removed, thus not requiring the same to be forcibly hammered out such as would be necessary in case the opposite side edge 24 thereof were parallel to each other. Each of the end sections 21 has an abutting edge 25 which accordingly is V-shaped when view from a bottom as indicated in Figure 5 so to accommodate the - converging sides 24 of the wedge-shaped intermediate sections 22.

Claims

THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:

1. An improved crank case oil pan, comprising in combina-tion, a plurality of six interfitting sections, and including an end section at each end and a pair of wedge-shaped sections therebetween, each said section including a flange having openings therethrough for receiving mounting bolts to fasten said sections to an under-side of an engine block, said bolts extending through a gasket fitted between said engine block and said oil pan, one end of said oil pan being downwardly relatively deep while an opposite end there-of is downwardly shallow, a vertical wall forming a shoulder between said deep and said shallow ends, said vertical wall extending across said wedge-shaped sections, each said section additionally including an outwardly turned flange along all edges that abut with mating-like flanges of an adjacent said section, bolt openings through said flanges receiving mounting bolts for securing said sections together, and said sections each being independently removable from said engine block without need of removal of adjacent said sections.
