FURNACE-DOOR FRAME.

Application filed February 20, 1925. Serial No. 10,609.

To all chem it may concern:

Be it known that I, EDWARD WILLIAMS, a citizen of the United States, and a resident of Monessen, in the county of VVestmoIe land and State of Pennsylvania, have in vented a new and useful Improvement in Furnace-Door Frames; and I do, hereby declare the followingv to be a full, clear, and exact description thereof.

My ..'invention relates to furnace door frames and has for its object the provision of a frame that may be made from standard metal parts, provided with an efficientcooling arrangement; having its welded joints all disposed at locations where they are effectively cooled by fluid that is circulated through the frame, and to .simplify and improve generally the structure and functioning of doors of this general character.

One form which my invention may take is shown in the accompanying drawing wherein Fig. 1 is a view, partially in front elevation and partially in section, of a door constructed in accordance with my invention; Fig. 2 is a rear elevational view there of; Fig. 8 isa view taken on the line 3-3 of Fig. 1; Fig. 4 is a view taken on the line 4-1 of Fig. 1, and Fig. 5 is a view taken on the line 55 of Fig. 2.

The apparatus consists of an upper tube 6 that serves as a header, or ,a manifold, and a lower tube 7 that also serves as a manifold. The

tubes

6 and 7 are connected by smaller pipes 8 that are welded or otherwise secured at their ends to said tubes, to serve as com municating passages between the

tubes

6 and 7. An angle-shaped member 9, preferabl of sheet steel or the like, is welded to one 1- end of the tube. The front flange of each angle 9 extending upwardly to a'point only about half way across the front face of the tube, as indicated at 9. The backwardly extending flange 9" of the angle 9 extends entirely-across the end of the tube. The flanges 9" are welded to the ends of the tube 6 so as to seal the same against leakage of water therefrom, and the upper edges of the flanges '9 are welded to the front face of the tube.

A front, plate 10 is provided which fits between the inner edges of the flanges 9' and is welded thereto and welded at its upper and lower edges to the

tubes

6 and 7 The plate 10 preferably extends only half way across the front faces of the tubes 6 angles and the plates.

vided with an inlet opening 16 that may be lines.

A rear plate 11 is welded at its side edges to the rear edges of the rearwardly projecting flanges 9 of the angles 9 The

pipes

6 and 7 are of a diameter greater-than the diameter of the pipes 8 so that spaces are left between the pipes 8 and the front plate 10 and the rear plate 11. The plate 11 is.

preferably curved at its lower edge and such edge is Welded to the rear side of the tube 7 on the line 12. At its upper edge the plate 11 is provided with a flange 13 by and 7 and is welded thereto on their median f said tube to the chamber formed by the The tube 6 is proconnectedto any suitable source of fluid supply. An outlet 17 extends throughv the walls of the .tube 6, into communication with the chamber formed by the plates and angles above described. H The tube 6 is preferably of less diameter than the tube 7, because the rear plate 11 'is'cut aw'ayat the..point 12 where it is welded to the tube 7 and 'it'is'desirable toavoid reducing the thickness of the plate 11 at its upper end where greater strength "is required- The tube 6.'must therefore be of smaller diameter in order thatv the plate 11 may be perfectly vertical.

It will be apparent that water or other I I cooling fluid introduced throu h the opening 16 will flow through the tu e 6-, tube 7,

opening 15 and to the outlet 17, in the directions indicated by the arrows, thus effectively cooling the door frame throughout substantially its entire area. The connections'between various parts of the apparatus are preferably eflecte by electric weld mg,

and it will be noted that,'particularly where theplates are welded. to the tubes, such effectively cooled than if the parts of the structure were joined at other pomts. There is therefore less tendency for the joints to be opened under action of heat from the furnace.

While the tube 7 is shown as being of arched form it will be apparent that it may be so formed as to provide an opening through the frame of substantially rectangular form, for example.

I claim as my invention:

1. A furnace door frame comprising an upper tube and a lower tube, front and rear 'plates welded to the front and rear faces 01 said tubes at substantially the median lines thereof, and means for directing a stream of cooling fluid through said tubes.

2. A furnace door frame structure com-- prising an upper header member, a lower header member, an inlet to said upper header member, communicating passages between said header members, the lower header member being open at one side, closure plates secured to the sides and ends of said header members to form a cooling chamber, and an outlet leading from said j'chamber.

3. A furnace door frame structure comprising an upper .tube member, a plate secured to each end of said upper tube member and extending downwardly, a lower tube member disposed between the lower ends of each of said plates and having an opening at one of its ends, a conduit providing communication between said tubes, side plates secured to each side of said tubes and said end plates, and cover members secured to the lower ends of said side and end plates.

4. A furnace door frame structure comprising an upper tube member, a plate secured to each end of said u per tube member and extending downwardly, a lower tube 1 member disposed between the lower ends of each of said plates and having an opening at one of its ends, side plates secured to each side of said tubes and said end plates, cover members secured tothe lower ends of said side and end tween said tu es, an inlet opening being provided for the upper tube and an outlet opening being provided leading from the chamber formed by said plates.

5. A furnace door frame structure comprising an upper tube member, a plate seof said. tubes and said end plates, and cover members secured to the lower ends of said side and end plates, the side plates being welded to the faces of said tubes at substantially the median lines of said tubes.

6. A furnace door frame composed of an upper tube member, a lower tube member, end members closing the ends of said upper tube members and extending downwardly, side plates secured to each side of said tubes and to the front and rear edges of the end members, a plurality of pipe connections providing communication between the said tubes and spaced longitudinally thereof, the lower tube being open at each end, and inlet and outlet passages being provided for permitting a flow of fluid through saidtubes and the chamber formed by said plates.

7. A furnace door frame comprising an upper tube and a lower tube, front and rear plates welded to the front and rear faces of said tubes, and means for directing a stream of cooling fluid through said tubes.

8. A furnace door frame comprising an upper tube and a lower tube, front and rear plates welded to the front and rear faces of said tubes to form a chamber, means for supplying fluid to said tubes, and communicatin passages being provided between said tubes and said chamber.

In testimony whereof I, the said Enwann WILLIAMS, have hereunto set my hand.
