PLATE-GLASS ANNNALING LEER.
To all' whom it may concern:
Be it known that we, EDWIN E. MILNER, residing at Scott Township, and WILLIAM J.
LYTLE', residing at Rosslyn Farms Borough,
Allegheny County, Pennsylvania, have invented a new and useful Improvement in Plate-Glass Annealing Leers, of whlch the following is a full, clear, and exact descr ption.
Our invention relates to plate glass annaling leers and particularly to a mufile leer of the zig-zag type.
An Ob]6Cl5 of our invention is such a device wherein the articles to be handled may be easily and readily introduced into and moved from'placeto place in the leer A further object of our invent on is such a device wherein the temperature inside the leer may be accurately controlled.
Further objects and the nature of our 1nvention will be better understood by reading the following description taken connection with the accompanying drawings forming a part thereof, and in which:
Figure 1 is a view partially in plan and partially in section of a devlce embodying our invention;
Figure 2 is a cross section on line II-II of Figure 1;
Figure 3 is a section on line IIIIII of Figure 2;
Figure 4 1s a plan view of one of the;v
tory material. The floor 3 is surroundedby the muflle chamber 4 in which the articles to be treated are placed. The chamber 4 1s surrounded by side walls 5 of any suitable material. The top wall of the muflie chamber is composed mainly of a plurality of longitudinally extending flues 6 arranged side by side and extending substantially the full length of the chamber. These flues 6 commumcate through headers 7 for the various chambers and the headers 7 are connected by flues 8 with the main flue 9, as best shown in Figure '1. The flue 9 leads to a suitable stack 10 for carrying the products of combustlon from the flues. The flues 6 may be formed of any opening 18 in the burner. into the burner through the channel 19 and Specification of Letters Patent. t t Aug 1 1922 Application filed August 16, 1921. Serial N6. 492,660.
suitable material such as tile, either of integral construction or built up in separate top and side members as indicated in Figure 3. These flues are supported by I-shaped key blocks 11 shown in section in Figure 3. The key blocks 11 aresuspended from channels 12, which are suprfosted by any suitable framework. The top walls of the flues 6 may be reinforced by a layer 13 of brick. or other refractory material.
At its front end each of the flues 6 communicates with a vertical combustion chamber 14. which extends upwardly through the one end wall of the muflie chamber. There is a single combustion chamber 14 for all of the flues 6. This combustion chamber 14 is provided with suitable burners 15, shown in detail in Figures 4 and 5 These burners may be used with either producer gas or natural gas. When producer gas is used it is brought into the burner through the flues or tunnel 16 and'enters the burner through an opening 17 which is in line with a similar Air is brought as shown in Figure 4 the air completely surrounds the gas opening 18in the burner.
The'flue 16 has an opening for each of the burners so that all of the burners are fed from a common source. If it is desired to vary the amount of gas passing through the burner, the burnerma be moved to the right or left as shown in igure 2, thus placing. the'openings 17 and 18 slightly out of register so as to cut down the amount of gas supplied.
I The device as shown in Figure 1 is provided with an opening 20 through which the plate glass to be annealed is introduced into the furnace. The plates of glass are introduced through the opening 20 on the floor 3. After they have remained in the first compartment A for the required length of time, a suitable tool is introduced through the opening 21 and the late is moved to the rear of the chamber, a r which a similar tool is introduced through the opening 21 and the late glass is moved into the chamber B. fter the same has remained in that chamber for the required timea tool is introduced through the opening 22 and the plate is moved to the rear of the chamber B and is then moved into the chamber C by a tool introduced through the opening 23 in the chamber B. From the chamber C the article is carried by any well known means through the cooling chamber D shown brokenofi' in Figure 1. The chamber D may be of any desired length depending upon the circumstances.
In the particular leer shown in the drawings there are twelve of the flues 6 for each of the chambers A, B and C, and each flue is provided with an oiltake 24. It will be understood, however, that the number of the fiues may be varied according to the size of the leerand that more oiftake connections may be provided if desired. The ofitake,
connection may be controlled by any suitable means if desired.
By reason of the arrangement shown, the temperature of the heating chambers may be accurately controlled to produce the desired results. Any desired number of burners 18 may be provided.
The advantages of our invention result from the provision of simple and effective means for heating the article to be annealed and for manipulating and moving that article from place to place through the zig-zag course of the leer in combination with the mufl le construction, whereby the article is heated indirectly from a plurality of fines.
lVhile we have described our invention in detail, we desire it to be understood that We are not to be limited to the exact arrangement shown, as many changes may be made in the details thereof without departing from the spirit of our invention- We claim:
1. A plate glass annealing leer having a plurality of heating chambers arranged zigzag with respect .to each other, the upper wall of each of said chambers being formed of a plurality of longitudinally extending heating flues, substantially as described.
2. A plate glass annealing leer having a plurality of mufile heating chambers arranged zig-zag with respect to each other,
the upper wall of eachof said chambers being formed of a plurality of longitudinally extending heating lines and a common com bustion chamber for each flue, substantially as described.
3. A plate glass annealing leer having a.
, plurality of mufile heating chambers arranged zig-zag, with respectto each other,
the upper wall of each of said chambers being formed of a plurality of heating flues, a common combustion chamber for each of said flues, and means for producing combustion in said combustion chamber, substantially as described.
4. A plate glass annealing leer having a plurality of muflle chambers arranged zigzag with respect to each other and a leerin line with the last of said chambers, the top wall of each of said chambers containing a plurality of longitudinally extending heating 'flues, substantially as described.
5. A plate glass annealing leer having a plurality of muffle chambers arranged zigzag with respect to each other, a leer in line with the last of said muflle chambers and communicatin therewith, the top wall of I plurality of mulfle heating chambers ar-.
ranged zig-zag with respect to each other, a
plurality of heating fiues in the top wallof each of said chambers, means for producing combustion for. each of said flues, and means common to all of said combustion producing means in the side wall of each of said chambers, substantially as described.
8. A plate glass annealing leer having a plurality of muflie heating chambers arranged zig-zag with respect to each other, a plurality of heating flues inthe top wall 0% each of said chambers, means for producing combustion for each of said flues, means com- -"mon to all of sald COIIlbllStlOD produclng means in the side wall of each of said chambers, 'and 'Ofi'take-meansfOr each of said "'fiues, and'means for connectingall of said ofi'takes together, substantially as described. ln testimony whereof, we have hereunto ,set our hands.
