RICHARD BATTLE, OF OKMULGEE, OKLAI-IOEIA.

THAWING DEVICE FOR AUTOMOBILES.

Application filed December 13, 1824.. Serial No. 755,805.

To all whom it may concern:

Be it known that I, RICHARD BATTLE, a citizen of the United States, residing at Okmulgee, in the county of Okmulgee and State of Oklahoma, have invented certain new and useful Improvements in Thawing Devices for Automobiles, of which the following is a specification. This invention relates to thawing devices, especially adapted for use in connection with water cooled engines.

Brieflystated, an important aim of this invention is to provide a steam circulating coil which may be convenientlyapplied to the outlet pipe of an automobile radiator without first detaching the outlet pipe or in any way disturbing the hose connection of the same. I

' is of highly simplified construction, easy to apply and cheap to manufacture.

Other objects and'advantages will be apparent during the course of the following description. I i

In the accompanying drawing forming a part of this application, and in which like parts throughout the same Figure 1 is a perspective illustrating the improved thawing device applied.

Figure 2 is a vertical sectional view through the device applied. V

Figure 3 is a side elevation illustrating a slightly modified form of invention, the metallic cover being broken away tomore fully illustrate the coil.

Figure 4 is a side elevation illustrating another modification of the invention, the jacket being broken away to illustrate the steam chamber. 1

Fi ure 5 is a perspective of the jacket ilnumerals are employed to designate like" i has its terminal portion inclined downwardlustr dted in Figure l.

In the drawing wherein for the purposes of illustration is shown a preferred embodiment of the invention, the numeral 5 general- 1y designates a motor vehicle having an engine 6 and a water circulating radiator 7 by means of which the heat in the water of the cooling system is dissipated.

Fig. 2 clearly illustrates'that the bottom .of the radiator is provided with a coupling member or outlet pipe 8 which is curved longitudinally, and has its rear end connected to a short hose 9. The upper end of the short hose section pipe 11. I

This invention is shown in connection with a Ford automobile, butit is to be understood that the invention is capable of use in connection with any water cooled automobile engine. y

The improved thawing device consistsof a coil 12' having its upper terminal portion connected to the overflow pipe let of the radiator by means of a short coupling 15, and the coil is as shownin Figure 1, provided'with a plurality of convolutions or turns which'form somewhat of a nest to receive the major portion of the pipe 8. The coil or steam circulating member 12 is more 9 is inturn connected to a or less elongated'to conform to the longitudinally curved pipe 8, and the convolu- ,tions of the steam circulating member are continuously inclined downwardly so that the products of condensation will not be trapped in thexdevice and possibly freeze.

- The presence of traps would allow the products of condensation to freeze and defeat the purposes of the invention.

The lowermost convolution of the coil 12 ly at'an acute, angle to provide an outlet 18, which extends through a metallic insulating terial. The cover 20 surrounds the major portion of the pipe 8, and protects the same from cold. The bottom ofthe metallic cover 20 is provided with an opening 24 for the reception of the ,draincock 25 at the intermediate portion of theoutlet pipe 8.

In carrying out the invention, the steam conducting member 12 is held in place by loo.

plied without first detaching the short pipe 8 or disturbing any of the water connections. This is so because of the peculiar formation of the coil 12 which fits up under the pipe 8 and contacts with both of the sides of the same. When the coil 12 has been applied to the short outlet pipe 8, the coupling member 15 which may be of any suitable material is employed to connect the meeting ends of the overflow pipe 14, and the coil 12 so as to establish communication between the dome of the radiator and the coil. The

straps

26 and 27 are now employed to securely hold the device in place on the pipe 8,andin case the water in the pipe 8 or the radiator 7 freezes and the engine started, the resultant steam will flow down through the overflow pipe 1% and through the coil 12 so as to melt the ice in the pipe 8.

It may be stated that the first place the water in the cooling system freezes is in the pipe 8 and in bringing about the meltingof any ice which may be in the pipe 8, the circulation of water is resumed.

In the form of the invention illustrated in Figure 3 the inventive idea involved is the same as illustrated in Figure 1. The major difference between what is illustrated in Figures 1 and 2 and what is shown in Figure 3 resides in the fact that the coil 80 is provided with an abrupt turn 81 which permits three convolutions to be employed at the forward portion of the connection 8. The addition of the third convolution at the lower portion of the connect-ion 8 substantially increases the radiating surface of the improved thawing device and consequently more effectively thaws the ice which may form in the connection 8. However, the addition of the third coil does not result in the formation of traps as the inclination of the coil is. maintained. Therefore, the steam is consequently flowing in a downward path and will not lodge in any portion of the coil. This form of the invention employs a jacket 85 similar in construction to the jacket 20 and held in place by fastening devices 86.

In the form of invention illustrated in Figures 4 and 5 the jacket is in the nature of a nest shaped elongated body to be applied to the water connection 8 so that the steam chamber 91 in the jacket 90 will extend about the major portion of the water connection to rapidly thaw ice in the water connection.

The upper edge of the nest shaped body 90 is provided with an attaching neck 92 which may be joined in anysuitable manner as by a coupling member 93 with the overflow pipe of the radiator.

The discharge from the steam chamber 91 is by way of an outlet 96 arranged at the lowestportion of the device so as to carry off all steam which enters the chamber. Figure 4 plainly illustrates that the bottom of the nest shaped body 90 is provided with a centrally arranged opening 97 to receive the drain member 98 of the water connection.

The outer side of the jacket 90 may be provided with a suitable heat insulating medium to prevent the cold air from coming in direct Contact with the steam containing jacket and condensing the steam therein. Suitable straps 99 are employed to secure the nest shaped jacket in place.

in manufacture the improved nest shaped body may be stamped or otherwise formed from two separate sections soldered or welded together. That is to say, the jacket is divided longitudinally or otherwise and the two parts joined in any suitable manner. The jacket may be of two sheets of copper pressed to form with the edges soldered together and having the pipe connec;

tion fitted to it in any suitable manner for connection with the overflow pipe.

The invention forming the subject matter of this application may be carried out by the employment of a cast iron jacket or pressed metal jacket with suitable baffles arranged to-divert the steam around and in direct contact with the bottom hose connection of the radiator.

Also the coil may be formed as an integral part of or soldered on to the bottom hose connection during the process of manufacture. Also a sectional pressed steel jacket may be arranged about the bottom hose connection 8 and connected to the dome of the radiator by the overflow pipe or otherwise, so that the steam will flow around and come in direct contact with the pipe 8.

It is further within the scope of this invention to embed the coil in molded asbestos tile without the use of the cover. It is thus seen that this invention is capable of a wide variety of mechanical expressions, and it is to be'understood that the form of the invention herein shown and described is to be taken merely as a preferred example of the same and that such minor changes in arrangement and construction of parts may be made as may remain within the spirit of the invention and scope of what is claimed.

Having thus described the invention, what is claimed is:

1. A thawing device for use on automobile radiator outlet pipes comprising an elongated nest shaped body having a pocket to snugly receive the outlet pipe of the radiator whereby the body may be applied to an automobile radiator outlet pipe without disconnecting the pipe, said body consisting of inner and outer spaced walls defining a steam chamber extending about the sides and bottom of the outlet pipe, and an inlet connected to the upper portion of said body and adapted for connection with the overflow pipe of the radiator, the lowest point in said body being provided with a steam outlet.
