no, a pm 11'; Y 0% the afngles :3 and 3, 3 and 22, are c imgy blocks 29. Each .5 m: opening or hole extending therethrough and the openings in one row of the blocks register with similar openings in the adjoining row of refractory blocks and with the holes in angles 3, 11 and 15, so that when placed in position within the frame of the door, the insertion of the rods or hollow pipes 23 secures the refractory blocks in place. In putting the blocks into place the joints preferably will be grouted with a mixture of fire-clay or other refractory material.
After the blocks 29 have been put into position in the door frame and are fastened in place by means of the rods or pipes 23, so as to fill the spaces between the sides and top and bottom edges of the door frame the angle 22 is secured in place on the door frame by means of the bolts 27 and 28, so as to maintain the rods or pipes 23 in place and prevent endwi'se movement thereof.
When hollow pipes 23 are employed in forming my improved door construction, air is circulated through the opening or holes extending lengthwise through the pipes, and, preferably, transverse openings 30 are provided' in the side walls of the pipes adjacent. to their ends. Transverse openings 31 in the top and bottom row of bricks are positioned therein so as to register withthe transverse openings 30 in the ends of the pipes, in this way insuring a. thermo-siphon action in the pipes, which will cause the cir culation of air and becoming overheats In the construction shown in Figs. 4, 5, 6 and 7 the construction is very similar to that in the preceding figures, and in these figures similar parts-have the same numerals applied with the prime mark added thereto. The door shown in Figs. 4, 5 and 6 has the removable angle 22, which is applied to what is shown as the top of the door instead I of .on the bottom of the door, as shown in Figs. 1, 2 and 3. The angles 2', 3 and the angles 15', 22' are connected at their ends by plates 5' and rivets 6, 7' and by. connecting angles 8 8 to the angles 4, 4 forming.
the sides of the door of Figs. 4, 5 and 6? The refractory blocks 29 are secured in place in the door frame by means of rods or pipes 23' and, when hollow rods or pipes are employed, transverse openings 30 are provided 1 n the'end of the pipes, which register with similar transverse openings 31 in the top and bottom rows of the bricks forming the door lining in the same manner and for the same purpose as in the preceding figures.
The advantages of my invention will be apparent to those skilled in the art. Bv the construction of the metal frame of the door of rolled commercial shapes in the manner shown and described and by the novel arrangement of the refractory lining for the door and the means employed in holding the lining 111 place, a door construction is obprevent the pipes from tained which is easily and cheaply made and in which the refractory lining can be readily repaired and renewed.
Modifications in the construction and arrangement of parts may be made without departing from my invention. The length. and width of the door may be varied. Instead of employing openings through the )IiCkS for the rods securing the bricks in place, the ends of the bricks may be provided with notches or grooves which will engage with the rods or pipes in securing the bricks in place, in which case the length. of the bricks will be same as the distance be-: tween the vertical centersof tlie ods, and other changes may be made withinfthe scope of my invention as defined in the appended claims.
I claim v l l. A door for furnaces or ovens comprising in combination a sectional refractory- 1 lining, a sectional metal frame adapted to surround said lining, and removable metal rods-within the frame engaging with the lining sections and the frame to secure the lining in place "therein, the ends of said rods engaging with the inner surfaces of the frame to prevent endwise movement of the rods in the assembled frame.
2. A. door for furnaces or ovens comprising in combination a series of refractory blocks, a surrounding metal frame in which the blocks are removably secured, removable hollow metal rods engaging with the blocks and frame in securing the blocks in place, said hollow rods having openings to permit circulation of air therethrough and means detachably secured to the door frame whereby the rods are held in position thereon.
3. A door for furnaces or ovens comprising in combination a sectional metal frame having means for det-achably securing the frame sections together, a refractory llnlng formed of bricks having registering openings therein, and a series of metal rods with- .in the frame and engaging the registering openings to secure the bricks in place in sax frame, the inner surfaces of the assembled frame sections engaging the ends of Said 115 rods to prevent reinoval thereof.
4. A door for furnaces or ovens comprising in combination a sectional refractpry lining, a sectional metal frame surrounding the lining andhaving means to secure the frame'sections together. and removable rods engaging with registering openings in the lining sections and door frame to secure the lining in place, said frame engagmg thfi ends of the rods toprcvent removal thereof 125 from the frame.
