skilled in the art to which it appertai'ns tomake and use the same.
This invention is directed to the provision of an improved construction for the walls of combustion chambers, such for instance, as a chamber having tubes in the walls thereof for a cooling medium or a chamber having tubes in the walls thereof for a liquid to be heated.
The invention is of particular utility in the construction of walls for liquid heaters lofthe type shown in Patent No. 1,085,341
granted to me January 27th, 1914, and this application is a division of the application for that patent which latter application was led May 21, 1907, and serially numbered 374,851.
The invention involves the provision of a wall for a combustion chamber consisting oit' a plurality of sheet-metal strips which are secured together at their lengthwise edges and arranged in the same general plane so as to form a wall, and a plurality of tubes for a liquid extending lengthwise of the strips and secured thereto. By constructing the wall in this manner, strips all of the same shape may be employed in the construction of combustion chambers diffel-ing in size and shape, the number and relative positions of the strips being varied as may be required to give the particular shape of combustion chamber desired. The
strips are preferably provided with one or.
more lengthwise' grooves in which the tubes are received, the tubes being secured to the stripsso as tofacilitate the transmission of heat to or from the liquid in the tubes. Each stripmay have two grooves formed therein adjacent to its lengthwise edges, and in assembling the parts each tube may be laid in the grooves at the adjacent edges of two adjacent strips, the strips being secured to opposite sides of the tube. In the latter case, the two grooves in each strip may be on the same side or upon opposite sides of the strip, and when the grooves are on opposite sides, each strip will be of S- shape.
I have illustrated certain embodiments of my invention in the accompanying drawings in which- Figures 1 to 5 are cross-sectional views of five different forms of walls for combustion chambers.
Referring to F ig. 1, the wall is shown as I consisting of a plurality of sheet-metal strips (l), each of which has the metal at its lengthwise edges curved so as to for-m grooves adjacent to those edges. vThe grooves so formed are adapted to receive tubes (2). The several strips (l) are arranged to face alternately in opposite directions so that the curved edges of two adjacent strips will coact with a tube. Each tube (2) is securedto the portions of the 75 strips (1) in contact therewith so that a wall is formed consisting of alternating strips (1) and tubesy (2). The several strips (l) 11e in the same general plane so as to form a wall, and the number and rela- 8() ,tive arrangement of the strips and tubes may be varied as is required to give the chamber the size and shape desired. It will be seen that each tube (2) is `almost completely encircled 'by the curved edge por- 35 tions of the strips (1), so that the transmission of heat to or from the medium within the tube takes place more readily.
Fig. 2 shows a construction closely similar to that shown in Fig. 1.. This construction constructing the plates '(3) in this manner 95 the tubes are more completely inclosed and the space within the combustion chamber is slightly enlarged.
In Figs. 1 and 2, the curved lengthwise grooves in each sheet-metal strip face in the same direction. In Fig. 3, each strip (4) is formed so that the two grooves face in opposite directions, the strip being of S- shape. Each strip so formed contacts with the inner side of one tube and the outer 10,5
side of the next tube. These strips (4) and tubes (2) are 'secured together as above described, lying in the same general plane so as to form a wall.
In Fig. 4, the several sheet-metal'strips 130- of the several tubes (2) is secured to one of the strips (5) extending lengthwise thereof. If desired, all of the tubes may be upon the same side of the-strips (5) of the wall, but I prefer to arrange the tubes as shown in Fig. 4, wherein alternate tubes (2) are onl opposite sides of the strips (5).
In Fig. 5, the strips (6) are shown as secured together, not by having their edges overflapped, kbut by having an additional strip4 (7) placed in contact .with the adjacent edges of each pair of adjacent'strips and secured thereto. In Fig. 5., each strip (6) is shown as having a length-wise groove formed therein at about the middle of the strip as shown at (8), and the tubes (2) lie in these grooves (8) and are secured to the strips in contact therewith.
I claim: v
l. In a liquid heater, a wall for the combustion chamber consistingof a plurality of sheet-metal strips secured together at their lengthwise edges and arranged in the same general'plane so as to form a wall, and
a plurality of liquid-containing tubes eX- tending-lengthwise of the strips and secured to the strips in contact therewith, substantially as described.
2. In a liquid heater, a wall for the co1n' bustion chamber consisting 4of a plurality.
of sheet-metal strips secured together at their lengthwise edges and arranged in the -Laietana same general plane to form a wall, each of said strips having a curved groove therein extending in the direction of the length of the strip, and a plurality of liquid-containing tubes extending lengthwise of the strips in the grooves thereinand secured. to
the strips in Contact therewith, substan- 4 tially as described.
In a liquid heater, a wall for the cornbustion chamber consisting of a plurality of sheet-metal strips each having grooves formed therein at its lengthwise edges, and a plurality of tubes each lying in the grooves at the adjacent edges of two adjacent strips of the wall and secured to said strips, substantially as described.
L .In a liquid heater, a wall for the coinbustion chamber consisting of a plurality of HUGO JUNKERS.
