WATER-RGULA'I'OR FOR ENGINE-RADIATORS.

pplication filed April 12, 1916. Serial No. 90,717.

To all whom t m ag/ concern: l

Be it kno-Wn that l, Cuantas L. Besten, a citizen of the United States, residing at Winfield, in the county oit Cowley and State of Kansas, have invented certain new and useful improvements in 1Weter-lR-egulators for Enginodtadiators; and l' do hereby declare the following to be a full, clear, and exact description oi the invention, such as will enableothers' skilled in the art to which it appertains to make and use the same.

This invention relates to the Water-cooling of internal combustion engines, especially those of automobiles; and the object of the invention is to provide for the maintenance of a uniform water-level in the radiator at all times. c

The invention has been devised tor use more particularly in connection With Water regulating apparatus, for which Letters JPat- 'ent No. 1,170,475 Were granted to me on the `first day of February, 1916 to which ref erence may be had for specilic details in connection with a brief and general description following.

In the accompanying drawing, Figure l is a sectional view illustrating the invention as applied to an automobile. Fig. 2 is a longitudinal section of the main water regulating device as shown in the above mentioned patent. Fig. 3 is a similar vievv ot the auX- iliary or overflow regulator which forms the subject matter o1? this application.

In the above mentioned patent the apparatus for maintaining a uniform Water-level in the radiator l is a surplus Water supply tank 2, preferably mounted under the cowl 3, at a somewhat higher level than the top of the radiator, and feeding said radiator by gravity through the medium of a Waterregulator 'shown in Fig. 2. This comprises a small chamber i, connecting with the supplytank by a pipe 5, and with the radiator by an outlet pipe 6. The lovv of Water through the outlet is controlled by a float 7 and a Water cut-oit consisting oi' a flexible tube 8 connecting with the outlet and a pinching blade 9 coperating with the float and the base of the float support to close said tube.

In the practical use oi the device above described a. diiiculty was encountered, arising out of the expansion and boiling ci the water in the radiator when the engine Was very hot. This would cause the radiator to overflow at the overlcw pipe, and thus connear the bottom of the radiator.

tinually draw Water from the surplus tank, eventually draining it. This difficulty is overcome by the present invention, the overflow being returned to the surplus tank, and the only Waste in the Water being due to slow evaporation, and practically negligible.

Referring now to the drawings, 10 denotes a small chamber conveniently located with respect tothe topot the radiator. Herein it is shown taking the place of the usual Jfilling nozzle, the body of the chamber being set down within the upper part of the radiator. The upper portion oi the chamber or vessel may serve as a filling nozzledLIand is provided With a tightly closing cap l2. The' bottom of this nozzle (the neck foi the vessel) forms a valve-seat 13 for a valve la carried on suitable stems l5 connecting at their lower ends With a float 16. 1When the Water in the radiator and chamber are at the normal level the valve is closed, as shown. ,When by evaporation the Water sinks belovv the normal level the float sinks, opening the valve. This opens an air-vent 17, normally closed by the valve, and thus permits vvater from the surplus tank to enter the radiator by the action of its regulating mechanism already described, it being understood that 'the radi- -ator 1s otherwise hermetically sealed, the

usual overflow pipe being dispensed With.

In the top of the valve la is seated a small valve'lS, Whose stem 19 runs in aly guide 20 forming part of a bridge. 2l across they nozzle. The small valve islield dotvn on the larger one by a light spring 22. From the neck oi the vessel a pipe 23 runs ba'ck to the supply tank. lt will thus be evident, that when there is an excess of Water or pressure in the radiator the surplus Water or steam Will be 'forced through the small valve 1 and back into the supply tank, to be there icondensed and so restored to the cooling system. l

:Owing to the agitation of the Water near the surface in the radiator, when boiling,`,the chamber containingthe Heat 16 should preferably not be open to the Water near the top, but should be fed by a pipe 24 leading to The main supply is shown as connected with this pipe, but the connection of the supply Withthe radiator may be separate, if desired. The vent at Q5 is for the escape of Water condensing in the neck of the vessel, and to prevent freezing therein in cold Weather.

.Having thus described my invention, I claim:

1. Combined with the radiator of a combustion engine, provided with an air-vent,

t a closure for said vent actuated by the Water-level in -the radiator, and means adapted to automatically supply water to said radiator.

f l 2. Combined with a vented radiator for a combustion engine, a closure for said vent actuated by the rising and falling of water in the radiator, an auxiliary water supply, means adapted to automatically deliver water therefrom to the radiator as needed, and

means coperating with the vent-closer to restore' to said water supply the surplus Water in the radiator due to boiling or expansion.

3. Combined with a radiator and means adapted to automatically supply it with `water at a normal level, a valve normally ed to close the radiator hermetieally, an auxiliary, light pressure valve, a chamber therefor, and a pipe leading fi'om said. chamber to the water supply.

5. Combined with a radiator and means adapted to automatically supply it with water at a normal level, a float-valve adapted to close the radiator hermetically, a chamber therefor, a Water connection of said chamber with still water near the bottom of the radiator, an auxiliary valve opened by light pressure from inside the ra diator, a chamber for said valve, and a communication of said chamber with the main water supply.

(3. Combined with a radiator and means adapted to automatically supply it with water at a normal level, a float chamber holding water at the Water-level in the radiator, a float therein, a valve closed thereby to tightly close the radiator, an auxiliary valve cooperating with the float valve, and opened lby light pressure from Within the radiator, a chamber therefor having air and drainwents closed by the .float-valve,

and a pipe leading from the auxiliary valve chamber to the main water supply.

In testimony whereof I affix my signature.

CHARLES L. BESLER.
