MELTING-FURNACE.

SPECIFICATION forming part of Letters Patent No. 753,122, dated February 23, 1904.

Application filed August 9, 1902.

To all whmn it may concern:

Be it known that I, HENRI J. J. CHARLIER, a citizen of France, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Melting-Furnaces, of which the following is a specification.

My invention consists of certain improvements in the melting-furnace for which I obtained Letters Patent of the United States numbered 687,557, dated November 26, 1901, the objects of my present invention being to so construct the furnace as to more effectively utilize the heat and to permit the use of the same opening in the furnace casing or shell, both as a charging-opening and as a pouringopening. These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which Figure 1 is a longitudinal section of my improved melting-furnace. Fig. 2 is a transverse section of the same on the line a a, Fig.

1; and Fig. 3 is a section on the same line, but showing the furnace discharging its molten contents. i

In Fig. 1 of the drawings, 1 represents the cylindrical shell of the furnace, and 2 and 3 the opposite heads of the same, the head 2 having a projecting trunnion 4:, adapted to a bearing 5, and the head 3 having a tubular trunnion 6, adapted to a bearing 7, the furnace-casing having a refractory lining 8, which is extended in the form of a contracted neck 9 through the hollow trunnion 6. The valved oil-supply pipe is represented at 10, and the valved air-supply pipe is shown at 11, all of these parts of the furnace being substantially similar to those of the patented furnace. I

The feed-hopper consists of a tapering casing 12 with refractory lining 13, and said feed-hopper in the present instance instead of being located at that end of the furnace remote from the neck 9 is located adjacent to said neck, whereby the products of combustion injected into the furnace through the Y neck 9 are caused to traverse the entire length of the furnace and after striking the far end of the same are caused to return toward the neck before being permitted to escape through the feed-hopper, the reverberating effect thus Serial No. 119,016. (No model.)

obtained materially increasing the heating effect of the flame and maintaining an increased temperature in the receiving-chamber of the furnace. In the present instance also the charging-hopper is detachable from the easing of the furnace, the lower portion of the hopper fitting into the tapering opening 14, formed in the shell and lining of the body of the furnace, and said hopper having a projecting flange 15, which bears upon the shell of the furnace and serves to steady the hopper in position thereon without interfering with the ready withdrawal of the hopper when necessary. By this means the hopper-receiving opening 14 in the main casing of the furnace can be utilized as a pouring-opening, as shown in Fig. 3, when the melting operation has been completed and the necessity of forming a special pouring-opening in the furnace is thereby obviated.

My present invention can, as will be evident, be embodied in furnaces intended to use natural gas fully as well as in furnaces using oil fuel.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. The combination of the body of the furnace having at. one end an opening for receiving the products of combustion, with acharging-hopper through which the products of combustion escape from the furnace, said charging hopper being located adjacent to that end of the furnace which receives the products of combustion,whereby a reverberating effect of the latter within the body of the furnace is obtained, substantially as specified.

2. The combination of the body of the furnace pivotally mounted so as to turn about its longitudinal axis and having at one end an axial opening for receiving gaseous products of combustion, with a combined feeding and pouring opening located in the peripheral portion of the body of the furnace closer to that end of the same which receives the products of combustion than to the other end, substantially as specified.

3. The combination of the body of a furnace pivotally mounted so as to turn about its longitudinal axis and having at one end an axial opening for receiving gaseous products of combustion, With a combined vent and to this specification in the presence of two sub-' pouring openinglocated in the peripheral porscribing Witnesses.
