7 Claims.
This invention relates to improvements in filtering devices and more particularly relates to an improved filtering device for use in the lubrieating system of an internal combustion engine. It is an object of this inventionto provide a construction of filtering device within a receptacie such as the crank case of an internal combustion engine which will insure its periodical removal into position to be inspected.
Another object is to secure an improved arrangement of parts for securing most effective operation and efiiciency of filtration of liquid.
a clearly shown in Fig. 1. x
Other objects will be apparent from the specification and from the accompanying drawings in which latter- Fig. 1 is a vertical sectional view through a filter device and the crank case of an internal combustion engine;
Fig. 2 is a bottom plan view of the closure upon which the filter device is mounted and looking along the line IIII of Fig. 1, and
Fig. 3 is a transverse sectional view taken along the line III-III of Fig. 1.
Referring particularly to the drawings, reference numeral I design-ates the crank case of an internal combustion engine. The crank case is provided with a drainage or outlet opening 2/ in its bottom wall. A closure 3 is adapted to seat against the wall of the outlet opening and is held in position by means of a cross bar 4 which is pivotally connected to the crank case at 5 and is detachably connected to the crank case at 6. The connection of the closure to the cross bar is effected by means of a pin 9 which extends between ears I0 protruding from the closure. The pin extends through an elongated slot I I in a protruding lug l2 upon the cross bar. Suitable sealing means i3 prevent leakage of liquid around the closure.
The crank case is adapted to contain a body of lubricant l6 therein which is to be subjected to filtration through a filter device. The filter device or assembly comprises a shell l8 provided with a base l9 having a delivery orifice for filtered lubricant at 20 which communicates with the main chamber of the crank case. The shell is supported resiliently upon the closure 3 by means of a 1181mm: L one end oi. which is secured to a suite c ormed at 22 upon the inner face of the closure. The opposite end of. the spring nests within an annular groove formed upon the under surface of the base l9, as is An inlet for oil to be filtered to the shell is provided opposite the discharge orifice 20. The
.asbestos or the like.
inlet comprises a body having a tubular portion 25, the inlet end of which is flared radially outwardly at 26. The positioning flange 21 protrudes radially from the body. A base portion 29 protrudes from the body into the shell. The base portion is provided with a passageway 30 which communicates at one end with the interior of the tubular portion and at its other end communicates with a plurality of transversely extending passageways 3| which open through the base portion into the shell l8.
Within the shell is a central vertical tube 35 supported at one end by the base I! of the shell in communication with the delivery orifice 20. The tube is supported at its upper end by the base portion 29. A plurality of perforations are provided throughout the length of the tube as can be clearly seen in Fig. 1. Surrounding the perforated tube 35 are a fine wire screen 36 and a wrapping of canton flannel or similar fabric 31. It is preferred to have this combination of means, but under some circumstances a single mesh device of suitable finenesscan be used and some of the advantages of the invention retained. Surrounding the outer wrapping 31 and substantially filling the shell I8 is a mass of fibrous or filamentous material 31 such as'silk, wool, The function of the fibrous material is to form a filter body which strains out the impurities of the oil.
The oil to be filtered is introduced into the filter device from a suitable source through a passageway 39 and pipe 40 which-protrudes from a wall of the crank case into the tubular inlet of the shell forming a sliding fit therewith which is liquid tight. A spring pressed ball valve 4| is mounted in a wall of the crank case communicating with the passageway 39. In the event that excess pressure develops in the filter, the ball valve will open and permit the by-passing oil to return to the crank case through a passage 42.
Inthe operation of the device,.a part of the circulating oil is delivered in known manner through passageway 39 into the shell of the filtering device where the oil passes through the fibrous material, the outer wrapping of cloth 31, the wire screen 36, and through the perforations into the tube 35 from which it is delivered through orifice 20 back into the crank case.
By the construction described the filter device is readily removable from the lubrication system.
- It is withdrawn with the closure each time that the crank case is drained of oil. Consequently it is subjected to inspection at frequent intervals to determine if it is operating at its proper efliciency. The removal of the filter device is facilitated by thesliding fit between the pipe 40 and tubular inlet portion 25. The filter device is protected from possible injury during use by the walls of the crank case. It is readily reinserted into operative position by closing the closure or the crank case.
While the invention has been described as applied to the crank case of an internal combustion engine, it will be understood that it is contemplated to apply it to other containers'in a fluid circulation system.
Various changes may be made within the terms of the appended claims in which it is desired to claim all novelty inherent in the invention as broadly as the prior art permits.
We claim:
1. In c mbination with the outwardly removable bottom closure for the bottom discharge opening of a receptacle, a filter assembly within the receptacle of lesser diameter than the opening and including an imperforate .shell having an outlet, filter material in the shell, means resilable closure for the bottom discharge opening of a receptacle, a delivery tube protruding inwardly from a wall of the receptacle toward the closure, 5. filter assembly of a lesser diameter than the awning within the receptacle including an imoerforate shell having an outlet, filter material .n the shell, means resiliently supporting the shell from the closure, and an inlet tube protruding from the shell into telescopic engagement with he delivery tube whereby the filter assemblyis withdrawn from the receptacle through the openng when the closure is removed from the opening. -3.
