Patented Feb. 3, 1931 malais CHARLES H. WAGNER, 0F MILWAUKEE, WISCONSIN, ASSIGNOR TO Li. J. MUELLER FUR/NACE COMPANY, OF MILWAUKEE, WISCONSIN, A CORPORATEON OF WISCONSIN FURNACE STACK 'Application led December rllhis invention relates to furnace stacks, and more particularly to the single wall y1flot air furnace stacks or pipes which extend throughv the walls of buildings are usually of rectangular form in cross section and are formed in sections to be connected together when placed in position in the building. It is desirable in assembling the parts to provide joints between the sections which while firmly holding the parts together will permit the separation of said parts if desired.
lt is one of the objects of the present invention to provide a furnace stack having the above mentioned desirable features and further in which the joints between sections are formed integral with portions of the metal of the stack sections.
A further obj ect of the invention is to provide a furnace stack in which the joints while firmly locking the partsl together permit the separation of the parts when desired.
A further object of the invention is to provide a furnace stack which is of simple construction, is strong and durable, and is well adapted for the purpose described.
llVith the above and other objects in view, the invention consists of the improved furnace stack and its parts and combinations as set forth in the claims, and all equivalents thereof.
ln the accompanying drawing, in which the same reference characters indicate the same parts in all of the views:
Fig. 1 is a side view of two stack sections provided with the improved joint;
Fig. 2 is a top view thereof;
Fig. 3 is a vertical sectional view thereof talren on line 3 3 of Fig. 2; and
Fig. 4 is a sectional detail view of the joint talren on a larger scale.
Referring to the drawing, the numeral S indicates the improved stack or pipe which is formed of two pieces of sheet metal joined together at the corners 9 and forming stacks of elongated rectangular form, as indicated` in Fig. 2. The upper edge portion of the pipe or stack is provided with integral eX- tensions 10 which are folded over outwardly 10, 1925. Serial No. 74,539.
downwardly and then outwardly and upwardly to form outer side grooved or chan-y neled portions 11. The upper edges of the portions are turned inwardly downwardly at an! angle to form yielding locking shoulders l2. The lower edge portions of the stack are Abent outwardly and downwardly to form sloping locking shoulders 13 and then bent inwardly and upwardly to reinforce the lower edge portion of the stack, as indicated by the numeral 14. The upper end portion of each sectionis slightly reduced in size to per mit the parts telescoping each other as indicated by the numeral 8. f
In use, the lower edge portion of the stack section is inserted into `the grooved portions 11 of the lower stack section until the locking shoulders 12 snap over the inclined shoulders 13 and the parts will be iirmly held in assembled and locked position. If it is desired to separate the sections, it is only necessary to pull the sections apart as the inclined locking shoulders will force the locking shoulders 12 outwardly and the parts. can then be easily f separated.
From the foregoing description it will be seen that the furnace stack is of very simple construction and will form a close connection between the parts and firmly hold the scctions together while permitting separation if desired.
What I claim as my invention is:
1. Ay furnace stack joint, comprising a lower stack section having upper edge eX- tensions which form outer grooves with elongated inwardly and downwardly angled loclring shoulders, an upper stack section having lower edge outwardly and downwardly inclined locking shoulders and inwardly and upwardly turned edge portions. which eX- tend into the grooves of the lower section, said inclined shoulders removably engageable with the locking shoulders of thelower stack section therebeneath.
2. A furnace stack joint, comprising a lower stack section of rectangular form having upper edge extensions which are folded over outwardly, downwardly and upwardly and then folded inwardly downwardly at oblique angles to form upwardly opening grooves and inwardly extending locking shoulders, the upper edges of said extensions projecting a considerable distance above the grooves to forni guides for an adjacent section, an upper stack section having lower edge outwardly and downwardly inclined locking shoulders and groove entering portions therebelow, said locln'ng shoulders being of approximately the width of the groove entering portions which removably enter the grooves of the lower stack section therebeneath, said inclined shoulders engaged by the locking shoulders of the other section to perniit an easy separation oiE the sections.
3. A furnace stack joint, comprising a lower stack section of rectangular form having upper edge extensions which are folded over outwardly, downwardly and upwardly and then folded inwardly downwardly at oblique angles to forni upwardly opening grooves and inwardly extending yielding locking shoulders, the upper edges of said extensions projecting a considerable distance above the grooves to forni guides, an upper stack section having lower edge outwardly and downwardly inclined locking shoulders and groove entering portions therebelow, said locking shoulders being of approximately the width of the groove entering portions which removably enter the grooves of the lower stack section therebeneath with the inclined portions engaging the locking shoulders to removably lock the two sections. together.
In testimony whereof, l affix niy signature.
CHARLES H. WAGNER.
