The loose materiel employed is desirably of such 2. nature that it may permit of the passage the 'electric'current. A suitable flu may well serve the'purposeyin whioh ease the flux is brought to e molten condition either before or after it is placed in contactwith the rail or other object and in such -molten condition constitutes the loose materiel with which my invention is practiced, it being well known in the art that flux a non molten condition is not a serviceable current conductor. In z'i'molten. condition, although a serviceable conductor, it'ofiers'sutlicient resistance to enable it further to be heated by the passage of the current, the heat being transferred-from the molten or loose meterisl to the metal object'so that the heat of the metal object may be raised to such a state as to enable-it to be joined to another metal object in'accordance with :the rocess ,of m invention.

By means of myinventionyeach rail bond terminal may be clamped into po- 5 against the rail web, inasmuch as the surface 5 of the rail bond terminal pressing against the ruil web is subject to the greatest heating action. 1 My invention, therefore, in its broad as fpect, resides in locating the loose mass of jects to be joined by fusion and locating the other metal object upon the other side of the ,first meta-1 object, in order that neither of the metal objects will interfere with the proper raising of the temperatures of both metal objects, and in order that other adperen may be secured. I

I will explain the method of my invention more particularly by reference to the accompanying drawing, showing one type of apparatus that may be employed in practicing the invention and also showing some metal objects in connection with whichsaid apparatus is used. r

'sition when the container isfirst placed material on one side of one of the metal obventageous results which will now" be ap- Cri" paratus and rail sections in association not being indicated in this figure for the sake "of clearness. Fig. 2 is a sectional view on line 2 2 of Fig. 1, showing some of the clamping mechanism that is employed. Fig. 3 is sectional VlQW on line 3 3 of F 1g. 1, showing other clamping mechanism that may be employed. Fig. is a perspective View of one form of rail bond terminal that may be employed in bonding the adjacent ends 01f adjacent rails together.

Like parts are indicated by similar characters of reference throughout the ditterent figures.

l have indicated the adjacent ends of two i -rail sections a a and two containers Z) 6, each having an open side that is closed by the rail web cagainst which it is placed, each container being), held in position by means of some suitable form of clamping mechanism such as that indicated at d, Fig. 2. As I have illustrated the containers 6, they are composed of non-metallic material, on which account the receiving spaces thereof, in addition to holding the loose material or iiux c that has contact with the web faces, also contain electrodes f located to the rear of the material I do not wish to be limited, however, to the use of containers composed of non-metallic material and to the use of electroces that are distinct in their construction from the containers. llach clamping device (Z, in addition to holding a container 5 in place against one side of rail web, may also hold a bond terminal 5 against the other side of the rail web immediately opposite the material 6. The terminals or electrodes 7L, complemental to the terminals or electrodes f, may be clamped upon the same side of the rail Webs c that are engaged by the bond terminals g, a clamping device for a terminal 72 being indicated at 2' in Fig. 8. The electrodes or terminals are in parallel relation with each other and. the electrodes or terminals 7b are in parallel relation with each other, these electrodes being included in a suitable circuit that will occasion the passage of current through the loose material c and the Webs 0, in order that the portionsof the webs that are in line with. the terminals 9 and the loose material 6 may become heated and may, in turn, suihciently heat the terminls g to enable them to fuse with the webs. In order to promote the fusion between the webs and the terminals spelter, or suitable comminuted metal, may be interposed. between the rail webs said terminals.

l i hilc have shown the contain the bonding terminals 9 as bein the webs of the rails it ceases do not wish to be limited to the portions of the rails that are to be united with the bond terminals.

ll'hilc I hate herein shown and particularly described pne way of practicing my in- Vention, l do not wish to be limited to all the details that have been specified, nor do I wish to be limited to the use of my invention in bonding the adjacent ends of adjacent rail sections together.

Having thus described my invention, I claim as new and'desire to secure by Letters Patent 1. The process of bonding the adjacent ends of adjacent rail sections together, which consists in causing loose ttusible electric current-comlucting material. to be in contact with one side of each rail section, passing; an electric current through said loose material and the rail sections to heat the loose material, heating the rails by said loose material, and holding the terminals of the rail bond against the sides of the rails opposite to those sides that are incontact with the loose material.

2. The process of bonding the adjacent ends of adjacent rail sections together. which consists in causing loose electric current-conductingmaterial to be in contact with one side of each rail section, passing an electric current through said loose material and the rail sections to heat the loose material, heating the rails by said loose material, and holding the terminals of the all bond against the sides of the rails opposite to those sides that are in contact with the loose material. I

8. The process of bonding the adjacent ends of adjacent rail sections together, which consists in causing loose fusible current conducting material to be in contact with one side of each rail section, passing an electric current through said loose material toheat the same, heating the rails by said loose material, and holding the terminals of the rail bond against the sides of the rails opposite to those sides that are in contact with the loose material.

i. The process of bonding the adjacent ends of adjacent rail sections together, which consists in causing loose current-conducting material to be in contact with one side of each rail section, passing an electric current through said loose material to heat the same, heating the rails by said loose material. and holding the terminals of the 'ail bond against the sides of the rails opposite to those sides that are in contact with the loose material.

7. The process of joining metal objects,

which consists in causing loose electric rent-conducting material to be in contact with one side of'one metal object, passing an electric current through said loose material and metal object to heat the loose material, heating said metal object by'the heated loose material, and holding the other metal object against a side of the first metal object opposite to that side that is in contact with the loose material.
