To all whom it may concern.-

Be it known that we, WILLIAM R. MILLER,

A residing at Pittsburg, and PAUL V. COLE, re

siding at Allegheny, in the county of-Allegheny, State of Pennsylvania, citizens of the United States, have invented certain new and useful Improvements in Continuous Ingot-Heating Furnaces, of which the following is a specification, reference being had therein to the accompanying drawings, forniing part of this speclfication, in wh1ch Figurel is a vertical longitudinal sectional. view, partly broken away, of our improvedcontinuous ingot-heating furnace. "Fig. 2 is a similar horizontalsectional view,ind1cated by the line H II of Fig. 1. Fig. 3 is an enlarged cross-sectional view, indicated by the line 111 III of Fig. 1. Fig. 4 is a sectional detail View showing one of the resilient mountings for the side bearing-rod. Fig. 5 is a view similar to Fig. 3', ind1catedby the line V V of Fig. 1. Fig. 6 is a detail viewillustrating the automaticuncoupling of the ingotsbuggy and also showing the operation of emerging from the water-seal trough.

- Our invention relates to im rovementsin continuous heating-furnaces or ingots, bil lets, &c., and comprises a longitudinal furnace opgn at eachend, rovided with an areaway t ough which t e ingot-buggies'and ingots pass upon supporting-tracks laid along the foundation, t e furnace being. pro: vided along its inner sides with Water-seal troughs with which downwardly-projecting water-seal flanges of the buggies cooperate in the manner hereinafter described.

- The invention also refers to the arrange-' ment of tracks whereby said flanges enter and emerge from the troughs'at the'ends of more ful ing a doublearched roof composed of lower and up, er sections 4 5, with an intervening longitu inal air heating passage 6. Jit one end of the furnace the roof structure is sloped upwardlytoward the end, as shown at the left side of'Fig. 1-,provid1ng agas and air buggy mixture chamber 7, into the previouslyheated air is introduced through t e'terminal air-port 8, forming the delivery endlfof air ma aria, 5, 1906.

(Not shown-5) suita le 15 is t eingot-buggy provided with a. 's1 1*-' erimposed ingot-sup ortingstru'cture o'fjfre- Fractory material, the oundation' of the buggy being ofrany suitable constructionysuch as; shown in the drawings, and" particularl in Figs. 3 and 5. The supporting-plates'io the or any'suitable portion thereof I are provlded at each side withidownwardly pro 4 jecting flanges 16, adapted to,-be' immersed in water contained in troughs 14 at each s'ide, whereby a water seal isprovided; so as to 'efs' fectually revent the issage'of air or; gasto or from t e furnace-chamber entir'elyalong each side thereof. w

As heretofore stated, the troughs 14 extend outwardl beyond the, ends of the furnace, and for t e purpose of im'rhersingthe flanges thereinto and causing them toemeigeoutwardly therefrom the supporting tracks 1 upon which the buggiesfiare'mountedf slope upwardly at eaeh'end pffjtheeifurnace," as

clearly shown at 1'8, Fig.1, by which arrangement it will be seen that as the buggies are advanced toward the furnace they will be gradually lowered, correspondingly lowering the flanges 16 into the troughs at the point of entrance, in which relation they will be maintained during the longitudinal travel of the buggies due to the horizontal parallelism of the troughs and tracks. Likewise the flanges will be gradually raised upwardly and out of engagement with the troughs as each buggy is drawn forwardly away from the other end of the furnace. 1t will be seen that by this arrangement the immersing'and emergence stems 20, horizontally arranged in receiving, "bearings 21, mounted against the inner sides of'the structural frame elements 13. These stems 20 are provided with coiled or spiral springs 22, which bear outwardly against the ends of the stems or against collars thereof and also against'inner suitable bearings. As

' thus mounted the rods or pipes 19 are forced outwardly into bearing engagement with the sides of the buggies, as shown, and tend to steady them, providing a resilient bearing throughout the entire interior of the furnace and preventing contact with the sides theretops of stationar of by the buggies.

e buggies make an interfitting engagement with each other at the ends by means of a male and female joint 23, as clearly shown in Fi 1, the abutting faces of the buggies neat y fitting against'each other, whereby gas-tight joints are provided.

The buggies are coupled together by means .of a latch 24, ivoted. at one end of each buggy on opposite sides at 25 and adapted to fit downwardly over suitable pins 26, corres ondingly arranged at the meeting end of the adjacent buggy. By these devices the buggies are con led and held tightly together as they are usfied or drawn through the furnace, and f dr the purpose of automatically uncoupling them as each succeeding buggy arrives at the exit end of the furnace the latches 24 are provided with sloping camabutments 27, arranged to engageover the posts or interferin -abutments 28; By these means the late es are disenga ed as each buggy arrives at theend of the rnace, so that the forward buggy may be drawn awa The operation will be readily understood from the foregoing description.

The device also providesa supplemental sealing construction.

The invention as a whole is simple, cfli cient, and capable of long-continued operation without liability to get out of order.

The features of improvement. may be applied to various constructions of furnaces or incorporated with existing structures and may also be changed or varied by the skilled mechanic to different details; but all such changes or variations are to be considered as within the scope of the following claims:
