DEVICE FOR SUPPLYING WATER T0 AUTOMOBILE-RADIATORS.

To all whom it may concern:

Be it known that I, \NILLrAM WELS- HAUSEN, a citizen of the United States, residin at Allenhurst, in the county of Monmouth and State of New Jersey, have invented certain new and useful Improvements in Devices for Supplying Water to Automobile-Radiators, of which the following is a specification.

This invention has as its object to provide a device for supplying water to the radiators of automobile and similar engines and for maintaining a constant water level within the radiator. As is well-known, drivers of automobiles vexperience inconvenience when the water in the radiator boils away and in fact unless the radiator is frequently inspected and kept properly filled with water, serious damage is liable to result not only to the radiator but also to the engine cylinders as they become overheated and the cylinder walls are scored by the pistons. Therefore,-the invention contemplates the provision of a water reservoir which may be conveniently filled and which is located upon the dash ofthe vehicle where a water gage upon the reservoir will bein plain view of the driver, conducting water from this reservoir to a valve chamber from which its flow to the upper head of the radiator is controlled automatically by means of a float actuated valve so that as the water level lowers in the said water head of the radiator, the valve will be automatically opened and water will be permitted to flow from the reservoir to the said water head.

Another object of the invention is to so construct the device that the same may be readily and conveniently applied to any of the ordinary types of radiators nowin use without disarranging the parts of the radiator.

In the accompanying drawings:

sectional view through the float and valve chambers of the device.

-In the drawings the numeral 1 indicates ingeneral a radiator of the ordinary construction and provided with the usual upthe rear side of the radiator at the top thereof in practically all types of radiators now 1n use, although it will be understood that where the radiator is not provided with such an extension, thepipe 3 may communicate with the upper water head through the rear side or wall thereof and the device embodying the present invention may be similarly rearranged.

The numeral 4 indicates a supporting bracket of any desired construction which is secured in any suitable manner to the rear side of the extension of the water head 2 and it serves to support the body provided with the float and valve chambers heretofore referred to. This body is indicated by the numeral 5 and may be of cast integral construction or built up in any desired manner, and the same comprises. a substantially cylindrical float chamber 6 and a smaller and substantially rectangular valve chamber 7 which is located at the rear side of the wall of the float chamber and communicates with the interior of the said chamber through an opening 8 formed in that portion of the wall of the float chamber which forms also a wall of the valve chamber 7. The chambers 6 and 7 are preferably'open at their upper ends and a suitable cover plate or cap 9 is removably secured in place thereon for the purpose of closing the said chamber. A water supply pipe 10 leads from any convenient portion of the wall of the float chamber 6 and communicates with the interior of the extension of the water head 2 of the radiator and serves to conduct the water from the float chamber into the said head, and similarly provides for a corhorizontally disposed partition 11 having a conical valve seat 12 formed therein, A

valve 13 of the needle type is arranged with-' in the valve chamber 7 above the partition 11 and has a conical seating portion 14 normally resting upon the seat 12 and closing the opening defined by this seat. A float 15 which is preferably cylindrical and of any desired construction is arranged within the float chamber 6 and is of a diameter nearly equalto the internal diameter of the said chamber so that while the float 15 may readily rise and fall with the level of the water in the said float chamber, it cannot have any considerable lateral play within thechamber. A lever arm 16 is pivoted at its forward end as at 17 to the upper side of the float 15 and near itsother end this arm fits loosely through an opening 18 formed in the wall which divides the float and valve chambers at a point above the opening 8, the wall of the opening 18 being preferably rounded longitudinally so as to afford a fuls crum for the lever arm 16 and permit of free rocking of the arm. At this point it will be understood that when the float 15 lowers within the float chamber, the forward end of the arm 16 will move downwardly and the arm will fulcrum upon the wall of the opening 18 thereby causing its rear end to swing upwardly.- In order that this upward swing of the rear end of the arm 16 may serve to raise the valve 13 from its seat so as to permit water to flow from the lower portion of the valve chamber into the upper portion thereof and thence into the float chamber, the said rear end of the arm 16 is preferably forked as indicated by the numeral 19 so as to straddle the shank of a screw 20 the head of which is indicated by the numeral 21 and is of such diameter as to be engaged by the arms of the yoke 19 when the said rear end of the arm 18 is swung upwardly; The shank of the screw 20 is threaded and adjustably fitted into a threaded bore 22 formed in the upper end of the valve 13 and, consequently, by rota tably adjusting the screw 20, the position of its head 21 with relation to the yoke 19 of the arm 16 may be varied so that the valve may be caused to open automatically when a selected predetermined water level has been reached.

A pipe 23 communicates at its forward end with the lower portion of the valve chamber 7 and this pipe leads from the bottom of the water reservoir heretofore referred to and which reservoir is indicated by the numeral 24 and is, as before stated, mounted upon the dashboard of the vehicle The waterglass for the reservoir is indicated by the numeral 25 and is preferably located at the rear side of the reservoir so as to be in full view of the driver of the machine.

A suitable cut-off valve 26 is the pipe 23 immediately below the reservoir 24 so that if desired the flow of water from the reservoir may be entirely out off, as for example when it is found necessary to completely drain the radiator and water jacket.

It will be understood that due to the maninterposed in 68 ner in which the arm 16 is fulcrumed through the dividing wall between the float and valve chambers, the employment of troublesome pivotal connections is obviated and the removal of the valve or the float is rendered easy when required. It will also .be apparent that the abutment screw 20 may communication between the chambers and with a second opening located above the firstmentioned opening and having its wall rounded longitudinally, and a lever arm connected with the float and operatively engaged with the valve and at an intermediate point loosely fulcrumed through said opening, the float chamber having an outlet opening and the valve chamber having an inlet opening and the latter being located below the valve. 2. A water supply device of the class described including a float chamber, a valve chamber in communication therewith, a float within the float chamber, a valve with in the valve chamber, a dividing wall between the chambers formed with an opening establish' ing' commnnication between the chambers and with a second opening located above the first-mentioned opening and having its wall rounded longitudinally, and a lever :lrm connected lvlvitili the1 floatand operativ y engaged wit t e va ve and at an intermediate point loosely fulcrumed through said opening, the float chamber having an outlet opening and the valve chamber having an inlet opening-and the latter being located below the valve, the said float being of a diameter nearly nal to the interior diameter of the float c amber.
