Description
PATENT QFFICE.
WALTER O. AMSLE'R, 0F PITTSBURGH, PENNSYLVANIA.
ANNEALING FURNACE OR LEER.
To all whom it may concem:
Be it known that I, WALTER O. AMsLER, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Annealing Furnaces or Leers, of which the following is a specification.
My invention relates to an annealing furnace or leer and more particularly to a new and improved roof structure for the annealin chamber of such furnaces.
As hereto ore generally built the roof of the annealing chamber has been constructed of tiles assembled to form an arch, the ends of the arch resting upon the side walls of the annealing chamber; in some instances the roof has been formed flat and metallic beams, hangers, etc. employed for supporting the roof.
For some purposes it is believed that a fiat roof is desirable, and the present invention is directed to such a construction, omitting however the objec'tionable features of construction such, for example, as metallic supporting members heretofore employed.
In the accompanying drawings, which illustrate applications of my invention,
Figure 1, is a vertical sectional view of an annealing furnace or leer embodying my invention;
Figure 2, a longitudinal sectional view of.
a portion of an annealing furnace, the sec-- tion beingtaken on line 2-2 of Figure 1;
Figure 3 a detail vertical sectional view showing a modified construction, the arched members formed integral with the flat tiles;
Figure 4 a detail longitudinally extendingi sectional view of the form of Figure 3; an
Figure 5 a detail sectional view showing still another form of roof construction embodying my invention.
Referring to the drawings, 2 designates the front wall of an annealing furnace or leer, 3 the top wall and 4 the side walls of the furnace.
In the furnace illustrated the combustion chamber 5 is located at the top of the structure and between the roof of the annealing Specification of Letters Patent.
Application filed May 21,
Patented May 9, 1922.
1920. Serial No. 383,258.
The annealing chamber is formed between the interlocked bottom tiles 13, the side wall tiles 8 and the roof structure.
The roof of the annealing chamber constitutes an important and characteristic.
feature of the present invention and as illustrated and as preferred, includes a plurality of horizontally disposed fiat tile members and a plurality of supporting or strengthening members all made of suitable refractory materials. The members constituting the roof are assembled in interlocked relationship and may assume different forms, this is particularly trueof the supporting elements or members.
In the form of Figure 1 the supporting or reinforcing members 14 each includes a wedge shaped body portion 01 having a curved or arched upper edge and an enlargement or head 6. In this construction the flanges c of the flat tiles 15 rest upon the heads I) of members 14;, and when assembled, form an interlocked structure. 16 designates a series of skew blocks forming the upper edge of the side walls of the annealing chamber and against which the end members 14 bear. The tiles 1 1 are provided along their edges In the form of Figure 3, the reinforcing members 14 are formed integral with the flat tile members 15, and in the form of Figure 5, the members 14", like the memwith tongues and grooves.
; supporting members bers 14 of the form of Figure 1 are separable or independent members. In this last mentioned form, however, the members 14 extend downwardly instead of upwardly as in the other forms.
What I claim is:
1. A fiat roof structure including a series of flat tiles and a series of arched members assembled in interlocked relationship.
2. A flat roof structure including horizontally disposed fiat tiles and tile supporting members formed of refractory materials.
3. A flat roof structure including horizontally disposed fiat tiles and arched tile formed of refractory material.
4. A flat roof structure including flat tiles and tile supporting members formed emma
