of Illinois, have invented new and useful Improvements in Liquid-Cooling Apparatus, of which the following is a specification.

This invention relates to apparatus for cooling the Water which circulates in the jackets around the cylinders of internal combustion engines.

The invention has for its object to provide a Water cooling apparatus ivhich is very simple in construction and highly efficient in operation, and in which no pump or mechanical device is necessary to produce a circulation through the Water jacket of the cylinders. The apparatus is also entirely devoid of thin metal Water cooling tubes, and the trouble'and annoyance of a clogged cooling system is therefore eliminoted. The apparatus also does not require a fan for cooling the Water.

The object stated is obtained by means of a novel combination and arrangement of parts to'be hereinafter described in detail, and in order tliet the saine may be better understood, reference is had to the accompanying drawing forming part of the specification. The preferred'embodiment oi the invention has been shown, but it will be understood that various changes and modifications may be made Without departure from the spirit and scope of thejnvention as claimed hereinafter.

in the drawings,

Figure 1 is a vertical section of the apparatus, and r Fig. 2 is a cross section on the line 2--2 of Fig. 1. p

Referring specifically to the drawing 5 denotes a casing suitably shaped so that it may be carried at the front end'jof a motor vehicle, it being understood thatthe cooling apparatus is designed more articularly for automobile engines. Near te top, the casing is entered by a Water inlet pipe 6 and near the bottom a water outlet pipe 7 is co nnected to the casing. These p pes are su1t-' ably connected to the water gasket otthe 1 engine cylinders, and as such connections are immaterial to the present invention the have not been illustrated. in the pipe is a check valve 8 to prevent a return fiow through said pipe to the casing 5.

Patented Dec. a, tore.

In the-casing 5 near the top thereof and 1 below the level ere the inlet connection'o is made, is a horizontal partition 9 havinga series of perforations 10 so that the Water discharged on the partition is broken up into minute particles and trickles down tothe bottom of the casing.

Below the partition 9, the interior of the easing 5 is crossed by a series of air tubes 11 the same being open atboth ends,'and

suitably fastened at their ends in opposite walls of the casing, these vvalls being the front and rear walls, so that When the car is in motion the air is. forced through the.

tubes. The air tubes are thus cooled, and'as they are located beneath thepartition 9 water trickles over the tubes and the heat is quickly extracted when the drops ofwater strike the cool tubes. vided into fine particles, and it does not flow in a large stream over the cooling tubes, the cooling action is considerably expedited.

the

As the wateris di On the front end of the casing 5 is an air inlet chamber 12 into which the front ends of the air tubesll open. The chamber has an air inlet 13 nearthe top, and above the tubes 11 the chamberlias a vent openin 14: leading from the casing 5 above said tn es. This opening permits the'escape of heat from the incoming hot Water.

The chamber 12. is provided with a sliding gate 15 for regulating the air intake in cold weather.

' When the Water in the water jacket of the engine becomes heated it expands and flows through the pipe 6 into the casing 5, and by the Way of the pipe 7 it flows back to the bottom of the Water jacket. As pointed out hereinbefore, the Water trickles down over the air-cooled tubes 11 whereby all its heat is extracted, and it flows back into the Water jacket of the engine properly cooled off.

The tubes 11 do not extend down to the bottom of the casing 5, so that this ortion of the casing forms a Water cham or 16..

The tubesjll'provide a large heat absorbing f area, and the number oftubes employed depends on the amount of cooling surface re quired to assure the best results.

W here the pipe 6 opens into the casing 5 it is formed with elongated spreader nozzle 17 extending in the direction of the length of the casing and serving to spread the Water throughout a large area.

I claim:

A liquid cooling apparatus comprising a casing having a liquid inlet and a liquid outlet, a transverse perforated partition in the casing between said inlet and outlet, and a series of air tubes extending across the inside of the casing between the partition anolvthe liquid outlet, and opening through opposite Walls of the casing, and an air chamber over the inlet ends of the tubes; said chamber having an air inlet and also having a heat vent from the casing on the liquid inlet side of the partition.

In testimony whereof I aflix my signature.
