APPARATUS FOR WELDING IRON AND STEEL- SPECIFIGATION forming part of Letters Patent No. 760,600, dated May 24, 1904.

' Application filed December 26,1902. Serial'No. 136,716. (No model.)

To alt whom it mayconcern:

Be it known that I, ABRAM O. ALLEN, a citizen of the United States, residing at Dayton,

in the county of Montgomery and State of- Ohio, have invented certain new and useful Improvements in Apparatus for Welding Iron and Steel; and I do hereby declare the following to be a full, clear, and exact description of the'invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the art of forging iron and steel, and more particularly to the" time or the welding will not be successfully accomplished, on account of the rapid cooling of the heated metals when exposed to the air. In case of failure, which is,of frequent occurrence where the parts to be welded are thin and of considerable extent, the parts must be again reheated, involving loss of time and more or less impairment of the parts themselves. To avoid this, I cement the heated parts together in a highly-heated atmosphere and in preference in the furnace itself.

In the accompanying drawings I have shown a furnace devised by me to carry out this method, and my invention is disclosed in the following description and claims.

Figure 1 is a longitudinal vertical section of my improved furnace. Fig.2 is a horizontal section on the line 2 2, Fig. 1. Fig. 3 is a section of the anvil on line 3 3, Fig. 2; and Fig.

4 is a section of the same on line 4 4:, Fig. 2.;

The furnaceA is of theusual form of a gas or oil burner heating-furnace. This furnace is provided at'the end nearest the door with an anvil B, projecting slightly above the floor of the heating-chamber. Thisanvil is firmly supported and has its upper end recessed, and

connected therewith are water-pipes b b for the hammer O, and-the roof of the furnace is provided with an opening a directly beneath the hammer. The hammer is so located and supported that it can drop through the opening upon the anvil. This hammer is supported in guideways controlling its upward and downward movements and'maybe raised and dropped by hand or by power mechanism, as preferred." Provision is also made for retaining the hammer when not in use above the roof of the furnace, as shown in the drawings. When raised to this position during the heating of the parts to be united, the aperture in the roof of the furnace is closed by united or welded are placed in the furnace behave been raised to the required temperature. The cover a is then removed, the parts are drawn forward on theanvil, and the hammer dropped upon them; Ifthe parts are of such extent that .theyare not completely united by this operation, they are then drawn forward and the hammer again dropped, and

thisis repeated until the parts have been completely welded or cemented together.

' What I-claim, and desire to secure by Letters Patent, is

1. A welding furnace having a heatinghearth for heating materials tov be welded,

and an anvil within said furnace adjacent to the heating-hearth, whereby the materials to be welded may be heated upon said hearthin upon said anvil, whereby the parts to be 1 upon said anvil, the whole combined and o I welded may be heated in said furnace and suberating substantially as described. jeeted to the action of the hammer Without In testimony whereof I have afiixed my sigremoving any of the parts from the furnace, nature in the presence of two Witnesses.

5 substantially as described.

/ 3. A Welding-furnace having a heating- ABRAM ALLEN hearth for heating materials to be Welded, a Witnesses: Water-cooled anvil adjacent to the said heat- EUGENE G. KENNEDY,

ing-hearth, and a hammer arranged to fall GRAFTON G. KENNEDY
