DEVICE EOB WITHDRAWING AND SEPARATING THE LIQUID CONTENTS OF THE CRANK- CASE OF AN INTERNAL-COMBUSTION ENGINE. I
Specification of Letters Patent.
Patented Aug. 7, 1917.
Application filed February 7, 1917. Serial No. 147,227.
To all whom it may concern:
Be it known that I, WEBB JAY, a citizen of the United States, residing at Chicago, in the countyof Cook and State of Illinois, have invented new and useful Improvements in Devices for Withdrawing and Separatmg the Liquid Contents of the Crank-Cases of Internal-Combustion Engines, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.
The purpose of this; invention is to provide an improved device adapted for the purpose of withdrawing liquid fuel from the crank case of an internal combustion engine when for any reason such liquid fuel has accumulated therein by passing the plstons, said device being adapted also for withdrawing lubricating oil from the crank case for the purpose of filtering and cleansing the same and returning it thereto. It consists in the elements and features of construction shown and described, as indicated in the claims.
In the drawings:
Figure 1 is a diagrammatic presentation of the several elements constituting and concerned in the operation of this invention, in their relation to the engine of an automobile. Fig. 2 is avertical axial section of the receptacle which constitutes the essential part of this invention together with its appurtenances.
Fig. 3 is a section at the line, 33, on Fig. 2. M The drawings show in connection with the engine of an automobile represented at 1, and having the crank case indicated at 2," the intake manifold at 3, and the carbureter at 4, a vacuum fuel feed device indicated in its general outlines at 5, and a receptacle, 6,
which constitutes with associated chambers the distinguishing part of this invention.
The receptacle, 6, has connections for alternately producing and relieving a partial vacuum therein, said connections in the contion that the alternation of conditions of partial vacuum and normal atmospheric pressure 1n the partial vacuum chamber, 8,
of the vacuum fuel feed device, is produced by any one of the methods which is familiar 1n this class of devices. The conduit connecting said partial vacuum chamber with the receptacle, 6, is always open, and thereby the condition of the partial vacuum chamber, 8, is reproduced in the receptacle, 6, wlthout other specific means for this purpose. The receptacle, 6, receives liquid from a plpe, 12, from the lower part of the crank case, and communicates downwardly with a chamber, 9, for delivery of the liquid con tents of the receptacle, 6, into said chamber, 9, a check valve, 9*, being provided at the discharge, which check valve is adapted to be opened by gravity flow of the liquid from the receptacle, 6, into the chamber, 9, and to be seated by the suction alternately operating in said receptacle, 6. Said chamber, 9, has an atmosphere inlet at 9, which is preferably provided with a check valve, 9, opening inwardly and adapted to be held seated by any pressure which may be developed in said chamber in excess of atmospheric pressure. In said chamber, 9, below the point of delivery of the liquid thereinto from the receptacle, 6, there is located. a filtering member, 10, designed and adapted for separating solid foreign substances from the liquid. This filteringmember may be of any material suitable for that purpose, such a woven-wire cloth and the like. .It is preferably formed as a slide, comprising a frame upon which the filtering cloth is mounted and stretched, said slide being insertible into its operative position in said chamber through a lateral opening, 9", in the chamber Wall, so that it may be readily withdrawn for cleansing, suitable means being provided for adapting it to close. air-tight the opening through which it is inserted, such as providing its head or outer end, 9,
with a compressible facing, I 9 seating against the outer surface of :the chamber, and providing a button, 11', for holding it' tightly closed.
In the chamber, 9, below the filtering slide member, 10, there is mounted a heating member, 13, which is most conveniently formed by extending a branch,.-13f, of the engine exhaust ,pipe through said chamber,
- 9, and inclosing it within'saidchamber in a partly insulating sleeve, 14:, filling the infter-space between said sleeve and pipe with asbestos or like insulating material. From' the lower part of the chamber, 9, a conduit, 15, leads back to the engine crank case, discharging thereinto at a level above the point at which the pipe leads therefrom. From a higher point in said chamber, 9, a vapor the chamber, 9, to be condensed on the way to the chamber, 24, and to be delivered into said chamber in liquid condition. Some vapor of water may also accompany the gasolene vapor and be condensed on the way to the chamber, 24. For the purpose of quickly separatmg the gasolene from the water, the familiar expedient of straining the mixture of gasolene and water through a chamois screen is employed, and for that purpose there is shown such a chamois screen or filter, 18, mounted in the upper part of the chamber, 24, forming a pocket into which the mouth of the siphon discharge pipe, 27, from the condenser, 17, dips, so that the liquid delivered through said mouth makes impact on the chamois pocket with the result that the gasolene, although lighter than the water, goes through the chamois,
while the water is detained, and overflows the margin of the chamois, escaping through a pipe, 28, which terminates near the bottom of the chamber, 24. The gasolene contents of the chamber, 24, arriving therein by passing through the chamois screen, passes out by the pipe, 19, which opens in the chamber, 24, and a distance above the bottom judged adequate to afi'orda suflicient trappage for the waterwhich' may accumulate therein, and which may be drawn ofl through cock, 30. The gasolene passing out through the pipe, 19, may be conveyed either back to the. gasolene supply tank,*26, or to the car bu'reter, as indicated by the pipes, 19 and- 19 respectively, a three-way valve, 20, being provided at the point at which the .conduit branches for one discharge or the other.'
It will be readily understood that the vacuum fuel feed device is not a necessity to this invention butthat when it is present, its partial vacuum chamber may be'utilized in the manner above described for maintaining the partial vacuum and atmospheric obvious that in the absence of the-vacuum iuel feed device, other means than the connection described between the chamber, 6,
and the partial vacuum chamber of saidvacuum fuel feed device may be employed for producing the alternation of partial vacuum and atmospheric pressure in the chamber, 6.
It will be obvious that the condensing of the vaporized gasolene may be dispensed with, the condenser being in that case omitted, and the gasolene vapor conducted directly to the carbureter, as indicated by a pipe, 22, which may be present, even when the condenser is employed, but being provided with a shut-ofl' valve, 23, to be closed when it is preferred to condense the gasolene vapor before returning it to the path of service in the engine.
