UNI-TED STATES BERNARD F. JOHNSON, OF JERSEY CITY, NEW JERSEY.

AUTOMOBILE ACCESSORY.

Application filed May 19, 1921. Serial No. 170,913.

To all whom it may concern:

Be it known that I. BERNARD F. JoHN- I SON, a citizen of the United States, residing at Jersey City, in the county of'Hudson and State of New Jersey, have invented certain new and useful Improvements in Automobile Accessories, of which the following is a full, clear, and exact description.-

In the operation of automobiles, difliculty is often experienced because of clogging of the oil or fuel supply pipes,'such as may be caused, for example, by lint frequently found in gasoline and oil, which condition is sometimes difli cult to detect or remedy and may necessitate taking down or removing the piping.

An objectof the invention is to provide an accessory for automobiles which will enable a motorist to quickly ascertain if an obstruction exists in a small conduit or pipe and if so to facilitate and assist its removal, which enables the convenient withdrawal of gasoline or oil when a quantity is desired for priming, cleaning spark plugs, or various other purposes, which may be embodied or used with present constructions with lit-v tle or no material changes therein, which occupies little space and adds little weight, and which is simple, reliable, durable, convenient and inexpensive. Other objects and advantages will be apparent from the following description of an embodiment of r the invention and the novel features thereof will be particularly pointed out in claims.

In the drawing:

Fig. 1 is a schematic elevation of certain parts of an automobile and showing one manner in which my invention is embodied therein and used,

Fig. 2 is a section through the multi-way valve, showing the normal position of its movable part when the sections of the pipe 5 are connected to one another.

Figs. 3 and 4 show similar sections with the valve parts connecting the branch pipe to either section of the pipe 5 and interrupting communication between the sections of the latter, and

Fig. 5 is a perspective of the movable element of the valve.

In the illustrated arrangement wherein the accessory is utilized in connection with the gravity feeding line between the gasoline tank and the carbureter, the storage tank 1 for the gasoline is connected through the usual shut off valve 2 with a small settling compartment 3 having a pet cook or valve 4 in its bottom to'drain the gasoline from the storage tank or to facilitate the removal of finely divided solids which getinto the tank and settle to the bottom of the compartment 3 as th gasoline passes there through. T he supply pipe 5 leads from the compartment 3 at one side thereof and a suitable screen 6 is provided at the entrance to the pipe 5 to prevent the-passageinto the supply pipe of lint and other solids which may clog or obstruct the pipe or carbureter.

This screen soon becomes clogged with lint and such other solids as may be suspended in the gasoline and prevents or seriously hinders the passage of the gasoline to the pipe with the result that the engine fails to act properly without any definite indication of the cause. The pipe 5 leads to a carbureter 7 of any suitable construction and interposed in the pipe at a point, adjacent the carbureter, is a multi-way valve 8,

which, in addition to its connections to the sections of the supply pipe between which it is interposed, is provided with a branch pipe connection 9 having an open end.

A pipe 10, which may conveniently comprise a flexible rubber hose, is provided at one end with a connector 11 which can be pressed over the uncovered valve stem 12 of an inflated tire 13. The tire may either be one of the tires in use or a square inflated tire such as commonly carried for emergency use. The connector 11 is provided with a pin 14 which enters the valve stem when the connector is applied thereto and depresses the valve piston so as to admit air from the inflated tire to the pipe 10. The other. end of the pipe is provided with a manually operated valve 15 and a terminal 16 by which the pipe 10 may be conveniently connected to the branch pipe 9. r

The valve comprises a casing 17 in which a frustro-conical valve element 18 is rotatably mounted. The element 18 has a groove 19 across the same, extending slightly over half the circumference, and with a passage 20 in the same plane with the groove 19 but extending from the inner wall of the groove obliquely outward to the periphery. The groove and passage are in the plane of the passages connecting the interior of the valve casing to the pipes 5 and 9. The stem 21 of the valve element 18 carries an indicator arm 22, and an operating button are 23 by means of which the valve is manipulated. The casing is provided with pins 2-l and 25 for limiting the extreme movements of the indicator arm. A s ring washer (not shown) acting between t \e casing and an end of the valve element may frictionally hold the latter in adjusted positions. The arm 22 is in a position at right angles to the main supply pipe sections 5 when these sections are in communication, this position is produced, the indication is that no obstruction exists in that section of the supply pipe. If the storage tank contains fuel and it fails to run out through the branch 9, an'obstruction is indicated. Any convenient source of pressure may be connected to the branch 9 to remove the obstruction] For example an air pump may be connected to the branch 9 which will blow loose the collection of solids upon the screen 6 or remove other obstructions. The pumps often fail to provide the necessary pressure and therefore the pipe 10 may be connected between the valve of an inflated tire and the branch 9. Upon an operation of the valve 15 the pressure of the tire which is usually around lbs. per square inch will be imparted to the clogged section and force out the obstruction. When the obstruction has been forced from the pipe into chamber 3 it may be removed therefrom through the cook or valve 4. The valve 8 may then be returned to intermediate position to re-connect the sections of the supply pipe 5 as before. By a movement of the operating button 23 clockwise until the indicating arm engages pin 25 the section between valve and the storage tank will be closed and the branch connected to the other section of the supply pipe and permit of the application of pressure thereto to remove obstructions in a similar manner. The amount of air used from a tire is very small and will not be suflicient to render it too soft for use. The pipe 10 with attachements on its ends occupy little space and can be conveniently carried in the tool box.

It will be obvious that the principle herein disclosed may also be employed in the removal of obstructions from the oil pipes, and that various changes inthe details and arrangement of parts may be made by those skilled in the art within the principle and scope of the invention.

I claim:

1. In an automobile having a conduit for conveying a liquid from one point to another, a valve interposed in said conduit and having a, branch leading therefrom, said valve beingfnanually operable to a plurality of positions, in one of which the sections of the conduit between which it is interposed are connected and the branch is closed, and in another of which communication between the sections is closed and the branch is connected to one of the sections, and a device adapted to be interposed between the valve of an inflated tire of the automobile and the branch for transmitting the pressure ofthe tire to a section of the conduit through" the branch and valve to blow out any obstruction in said conduit.
