bustion engines, and more particularly re lates to such a device adapted for use on automobile radiators to prevent the lower portion or outlet thereof from freezing inextremely cold weather especially after the automobile has been started.
In' the operation of automobiles in cold weather, it is well-known that difficulty is often experienced in preventing the lower portion of the radiator or circulating system from freezing, especially when the circulation through the radiator is obtained by the thermo-siphon principle, used in numerous makes of automobiles. As the water or other cooling-medium flows through the radiator, .it rapidly .cools, sometimes to the extent that when it reaches the outlet at the bottom of the radiator, it will freeze and obstruct'the flow therethrough, thereby causing the water in the cylinder jacket to be heated to the boiling point after which it will rapidly be dissipated in the form of steam' though the usual overflow pipe provided in the-radiator. It is, therefore, desirable that means he provided whereby the water will be prevented from freezing in the'lower portion of the radiator and thusobstructing the flow of water therethrough, and it is-theobject of this invention to provide a simple and eflicient method: and means whereby the frozen section of the systemwill immediately be thawed by the steam generated in the system, as a result of the obstruction caused by the frozen portion.
A further and more specific object of the invention is to provide a steam jacket around the outlet pipe of the radiator which has a connection with the usual overflow pipe of the radiator so that steam escaping through the overflow pipe will be discharged into the steam jacket, thereby thawing out the frozen section of the radiator.
A further object of the invention is to provide a simple andinexpensive anti-freeze attachment for a gas engine cooling system, and particularly the radiator of an ordinary automobile, which may easily and quickly beattached thereto in cold weather and readily be detached therefrom, when desired, as in warm weather when there is no use for the device.
Other objects of the invention will appear from the following description and the accompanying drawings and will be pointed out in the annexed claims.
In the drawings, there has been disclosed a structure designed to carry out the various objects of the invention, but it is to be understood that the invention is not confined to the exact features shown as various changes may be made within the scope of the claims which follow.
. In the accompanying drawingsforming a part of this specification,
Figure 1 is an elevation of a radiator showing: the invention applied thereto;
Figure 2 is a vertical sectional view'on the line 22 of Figure 1 showing the steam jacket enclosing the lower portion 'or outlet of the radiator;
Figure 3 is a detail sectional view on the line 3-8 of Figure 2. I
In the selected embodiment of the invention here shown, there is illustrated a ra- :1
diator of ordinary construction, comprising the upper water chamber 4, lower water chamber 5 and the cooling tubes 6 interposed elbow to preferably provide a. flexible con 'nection between the radiator and the engine water jacket, (not shown). The usual inlet connection 12 is shown depending from the upper water chamber 4 and this connection.
is also adapted to be connected to the water jacket of the engine.
A'feature of this invention resides in the novel means provided for thawing out the lower portion or outlet elbow 9 of the radiator should it be obstructed by water freezing therein in cold weather. Such means preferably consists in the provision of a steam jacket'or casing 13, preferably of a flexible material, which is so arranged as to substantially enclose the lowermost portion of the elbow 9, as shown in Figures 1 and 2. This jacketis suitably secured to the elbow by means of a bracket 14 .securely The usual overflow clamped to the elbow 9 preferably by means V of a clamping bar 15 and bolts 16 (see Fig ure 3). The bracket 14 is shaped so as. to clampthe upper edge of the flexible jacket or casing; against the usual flange of the elbow 9, a portion of it also being securely clamped against the inwardly extendingneck around: the outlet'elbow 9'by me'ansot the ste'anrjacket or casing: 13. An opening is provided in the lower portion of the-casing 18 to provide"clearance.for the usual drain cock l8, and this opening" ispreierablyvof such size as to permit the live steam being discharged into the casing" to escapetherethrough as indicated bythe arrows in Fig ure- 1, thereby providing treecirculation of stean'raround the-lower portion: of theclbow 9." k i From the foregoing, therefore', it will' be readily seen that by the employment-0tthis novel method' and means tor-preventing the lower portion or outletio't aradiator from freezing, the" usual danger of" radiators freezing iiir cold weather will be practically eliminated.- Should' the outlet 9', however,
freeze, and the passage of water there through be obstructed by ice, suclr obstruo'-' tion will immediately cause the water in- I the coolingqacket' ot the engine to be gen.-v
erated into steam, which willbe discharged through the overflow pipe 7 into the OlliLIIlber provided around the elbow-by the jacket or casing: 13' resulting: in immediately thaw-'- ingthe frozen section and .re-establishing. circulation through the radiator;
The construction of this novel device is very simple and'inexpensive, and is such that it may easily and quickly be attached-i to the radiator of an ordinary automobile and may as readily be removed therefrom when not" needed, as in: warm: weather. As a result of the jacket 13, preferably; being constructed of a' flexible material, it may conveniently be folded and packed-inte a comparatively small space in thej tool box or the" automobile or other suitable place,
when: not inuse. If desired however, thejacket 13 may bepermanently left on the outlet elbow of the radiator and only the hose v connection 17.be detached, When the device is not in use.
