' CONDENSER I FOR HECTOR-VEHICLE -RADIATGRS.

Applicati'on filed-August 27, 1923. Serial 310.6533610.

To all 10710122. iii-may concern:

Be it known that we, RANDALL D. GRIF- rum and CHARLES Soo'r'r IIUNTER, citizens of. the United States, and residents of Des Moines, in the county of Folk and State of Iowa, have invented acertain new and useful. Condenser for htiOtOT-VQhiCle vRadiators, of w ich the following is a specification.

The object ot-our-invention is to provide a condenser for motor vehicle radiators.

Moreparticularly-it isour object .to pro vide a condenser adapted to be mounted on the radiator cap and comn'iunicating with the interior of the-radiator, which condenser is of simple, durable and inexpensive and I Jconstruction for causing the condensation particularly i' alcohol vapors, and causing the liquid of condensation to (low back into the radiator.

With these and other objects in View, our invention consists in the construction, arrangement and combination of the various parts of our device, whereby the objects conten'iplatcd are attained, as hereinafter more fully forth, pointed out in our claims, andillustrated in the accompanying drawings, in which: 7

Figure 1 shows a front elevation of a radiator cap and condenser embodying our invention.

Figure 2 shows a side elevation of the same. i

Figure 3 shows a horizontal, detail, sectional view taken on the line 33 of Figure 1. v

Figure 21; shows vertical, sectional view tel-zen on the line 1--4cof Figure 2; and

Figure 5 shows a vertical, sectional view taken onthe line 5 5 of Figure 4.

It is well-known that in some types of automobiles, particularly the Ford, the contents of the radiator become very hot and in winter when alcohol is used with water as a non-freezing solution for the radiator,

the alcohol vaporizes rapidly and is lost in the form of vapor.

we have provided a condenser of novel structure for receiving the vapor from the radiator, condensing it and causing the liquid of condensation to flow back into the radiator.

Our improved condenser is used in combination with a radiator cap indicated in the accompanying drawings by the reference character 10.

Our improved condenser comprisesahollow body or member 11 preferably composed A. B and C somewhat like starpoints.

The lower part of the body 11 is larger and all the parts are so arranged. as to drain toward a common point D.

A tube 13 is received in a suitable open' ing 1% in the upper part of the cap and has a nut 15 screwed on its lower end and an annular shoulder 16 above the cap.

The lower central portion ofthe body or member 11 is tapered from side to side to the connecting edges except at the common point D, where the member 1]. is shaped to snugly receive the tube 13 to which the sides of the member 11 are thus fitted, so that the tube 13 serves to reinforce and strengthen the member 11.

The tube 13 is open at its upper end as at 17, which projects substantially upwardly into the hollow interior. of the member 11.

The tube 13 is provided with one or more openings 18 just above the common lower point D, so as to permit free drainage of the liquids of condensation from the member 11 into the lower part of the tube 13.

In the practical use of our improved condenser, the alcohol and steam passes upwardly from the radiator into the cap 10 and through the tube 13.

The greater part of these vapors pass from the upperend 17 of the tube into the member 11 and diifuse through all .parts of the member 11 including the projecting points A B and C. V

The meniber'll with its projecting hollow portions is subjected to currents of passing cool air, resulting inthe condensation of the vapors in the condenser.

All the star points and the lower part of the member 11 are so arranged as to drain toward the common point D, where the liquids pass through the openings 18 and downwardly through the tube 13 to the radiator.

The thin walls 01 the member 11 and the material and construction thereof are such that it some slight pressure should exist in the member 11, the Walls may spread somewhat toward and from each other at their central parts.

The condenser may be made in a variety of forms, either in combination With the cap or as a separate attachment, and it is not our intention to limit ourselves to the particular form of condenser disclosed herein, and it is our purpose to cover by our claims any modified forms of structure or use of mechanical equivalents, which may be reasonably included within the scope 0t our claims.

e claim as our invention:

1. In a condenser of the class described, a hollow member having projecting hollow portions, adapted to drain to a common point, a tube entering said member at said point and projecting substantially into said member, open at its inner end and adjacent to said point and serving to reinforce the walls of said member.

2. In a condenser of theclass described, a hollow member having projecting hollow portions and comprising spaced resilient walls connected at their edges and capable of some movement toward and from each other except at said edges, adapted to drain to a common point, a tube entering said member at said point and projecting suh stantially into said member, open at its inner end and adjacent to said point and serving to reinforce the walls of said menr ber. v

3. In a condenser of the class described, a hollow member having projecting hollow portions adapted to drain to a common point, a tube entering said member at said point and projecting substantially into said member, open at its inner end and adjacent to said point and serving to reinforce the walls of said member, and a radiator cap mounted on said tube, having the tube projected through it.
