METHOD OF .SOLDERING RADIATORS.
Application filed October 2, 1926. Serial No. 139,098.
My invention relates to.a method for constructing devices which are employed for changing the temperatures in liquids, and which may be especially designed for lowera ing the temperature or cooling the liquid used for preventing overheating in internal combustion engines, and an object of my 1nvention. among others, is the product1on of a method for making devices of this class, as a radiator, that shall be simplein construction and particularly efficient in operation.
A method embodying my invention and in the practice of which the objects herem set out, as well as others, may be atta1ned,1s illusl5 trated in the accompanying drawings, n which Figure 1 is a view of a fragment of a r ad1ator showing the parts assembled preliminary to the step of securing them together.
Figure 2 illustrates a vatcontalnlng a material for securing the rad ator parts together, and in which the radiator is dipped for this purpose.
Fi ure 3 is a view similar to Figure 1 and showmg the parts after treatment inthe vat shown in Figure 2.
Figure 4 is a view'illustratmg an electrplating apparatus by means of wh ch the outer coating is removed from the rad1ator.
Figure 5 is a view similar to Figure 1 but illustrating the appearance of the radiator parts after treatment in the device shown 1n Figure 4.
In the construction of devices for changing the temperature of liquids, and especially in the formation of radiators-and like structures.
employed in automobile construction, as is we 1 known, copper is a metal possessing a' high degree of conductivity, but the userof such a metal has heretofore been limited, owing to the difficulty in securing radiating elements com osed of copper in place, and in some cases w ere copper has been used the advantageous features of this conductivity have been much lessened from the fact that the conducting plates have been covered with. other metal used to secure the plates in position.
By the use of my invention illustrated and .m described herein, I have provided means whereby conducting elements composed of copper may be secured in place as to tubes for conducting liquid, in a very simple and expeditious'manner and in such way that the as surfaces exposed to the action of air currents shall be of copper, or other proper material.
secured to the'tubes in the manner now to be described. a
Each of the plates 9 is provided with openlngs 10'through which the tubes 6 extend, and these openings are preferably provided with flanges 11 to closely fit the tubes.
In practicing my invention a tube and plate structure is formed by assembling the necessary number of tubes and plates in their proper relative ositions, and while maintaming said mem ers in such positions in any desirable way the structure is dipped in a molten bath 20 of any material suitable for securing the tubes and lates together, said material being contained in a vat 21. This treatment, when the soldering material cools, will securely fasten the plates to the tubes, it being understood that the plates and tubes, either or both, are composed of metal. The treatment above described, however, will coat the plates and tubes with the soldering material, and it is my purpose, therefore, to remove this material so that the copper surfaces of the tubes and plates shall be exposed.
In securing or soldering the plates and tubes together tin in a molten state may .be emloyed and after the treatment just described it will be found that this material has entered the spaces, as at 12, between the tubes and 95 plates.
The coating 13 of tin or other material may be removed in any suitable manner, it being possible'to accomplish this purpose in dificrent ways, but I have found that this coating 1 may be removed or stripped off in aready manner by employing an electroplating apparatus in which the radiator is placed in an electrolyte 14 contained in a tank 15, the radiator constituting the anode to which the posi- 1 tive wire 16 of an electric circuit is connected. A cathode 17 is suitabl arranged in the electrolyte to receive the eposit of tin from the radiator or anode, the cathode being connected with the negative wire 18 in such elec- 110 trio circuit.
- 19 are retained in the joints between the After the coatin 13 has been removed in the manner above escribed, or by an other suitable means, it will be found that eposits plates and tubes, thereby securely fastening said parts together, and the-copper tubes and plates are left in their original condition with the entire outer surface of the structure constituted of copper and without any coating of other material.
a While cop er has been mentioned herein as a material 0 which the tubes and plates are composed, and while tin has been mentioned as a material for soldering or securing the parts together, it will be understood that the invention is not limited to any particular kind of materials for these purposes, but that .any suitable material may be employed in the tubes and plate structures, and anysuitable material may be employed for soldering or securing the radiator members together.
In accordance with the provisions of the patent statutes 1. have described the principles of operation of my invention, together with the device which I now consider to re resent the best embodiment thereof, but I esire to have it understood that the device shown is only illustrative and that the invention ma be carried out by other means and applie to .uses other than those above set out.
I claim- 1. The process of securing members together which consists in assembling said 'members leaving pockets at the joints therebetween, applyin a coatin to the outer surfaces of said mem ers and simultaneously filling the pockets with the coating material, and then removing the coating material until the surfaces of the members with the exception of said pockets are free of the material.
2. The process of securing members together which consists in assembling said members leaving ockets at the joints therebetween, fillin said pockets and coating said members by dipping the assembly in a bath of fused metal, and then removing the coat- -ing material until the surfaces of the members with the exception of said pockets are free of the materia 3. The process of securing members together which consists in assembling said members leaving pockets at the joints therebetween, applying a-coating to the outer surfaces of said members and simultaneously filling said pocketsto produce an excessive deposit at the joints, and then placing the assembly in an electrolyte through which an electric current is passed to uniformly remove the coating material until the surfaces of the members with the exception of said pockets are free of the material. -1
4. The process of securing members together which consists in assembling said members in final relative positions and leaving pockets at the joints therebetween, fillin said pockets and uniformly coating sai members by dippin the assembl in a bath of fused metal, and t en placing t e assembly in an electrolyte through which an electric current is passed to uniformly remove the coating material until'the surfaces of the members with the exception of said pockets are freed of the material.
5. The process of securing members together which consists in assembling said members and leaving pockets at the joints therebetween, applying a coating of molten metal to the outer surfaces of the members and simultaneously filling said ockets to produce an excessive deposit at the joints, permitting said metal to harden, and then strippingthe hardened metal toa uniform depth from all exposed surfaces of the members until the surfaces with the exception of the pockets are freed of the deposited metal.
6. The process of securing members together which consists in assembling said. members in their final relative positions leaving pockets at the joints therebetween, dipping sa'id assembly in a bath of molten metal to uniformly coat the exposed surfaces with the exception of the joints where an excessive deposit is made due to said pockets, and then removing the deposited metal by continuing to uniformly strip the same from all exposed surfaces of the assembly until the metal deposited within said poclrets is exposed when the stripping action is stopped.
7. The process of securing members together which consists in assembling said members to create joints therebetween, coat; in g said members by dipping the assembly in a bath of fused metal thereby depositing an excess quantity and thickness of metalin the angle at said joints, permittin' said do osited metal to harden, and then stripping t e hardened metal to a substantially uniform depth over all ex osed surfaces until the surfaces of the members are bared except in the angle at said joints.
