Serial No. 355,883.

This invention relates to ovens.

In the case of ovens of relative large size or length the construction becomes important. The oven must be of sufiicient strength to render the proper service and yet must be of such a structure as to be efficient. In manufacturing plants it may become desirable to change the location of the oven and therefore the oven should be of such construction m as to be capable of easy removal and re-erection.

Une of the objects of this invention is to provide an oven that can be easily and cheaply erected and one that will permit of disassembly and easy removal and ready re-erection. Another object of the invention is to provide an entirely new type of structure which will give the proper strength and rigidity with relatively light weight. A furao ther object of the invention is to eliminate structural construction. A further object of the invention is to form the oven from panels which are units not exceeding such size as will not permit of buckling under the heat.

A further object of the invention is to provide an oven wherein the panels are interlocked, supported and sealed by posts. A

further object of the invenion is to provide an oven wherein the panels and posts are made of sheet metal filled with heat insulating material. Still another object of the invention is to provide with the aid of strengthening members the required rigidity and strength to the sheet metal posts and panels in order to eliminate structural members. A further object of the invention is to reduce heat losses by heat transmission or radiation from the interior.

Figure 14: is'a detail view of the 2 bar Figure 6 is a top View of two panels with spacing strips 4 is preferably by welding although they may be secured in any other well known manner. Spacing strips 4 further function to retain the heat insulating material and by reason of their reduced area reduce the losses due to. heat transference from the inside wall 2 to the outside wall 2'.

Secured to the sides of each panel 1-, adjacent the ends are strengthening 2

members

the walls 2, 2', being bent around the outside edge of the

Z members

5, 5. Spacing strips 6 join the Z members 5, 5', and function identically, as spacing strips 4. The

Z members

5, 5, at the top and bottom are notched as shown in Figure 14 to permit of the horizontal post abutting the vertical posts for strengthening purposes. The posts 7 have a somewhat similar c nst uction. They are formed of two channels 7 7", se arated by spacers 8 which are likewise wel ed preferably to the exterior of the corresponding legs of each channel comprising the post 7 to form a post 7 as shown in top plan view in Figure 12. The vertical posts 7 may contain a stifiening angle 9 therein which angle can be utilized to secure the post to the supports of the oven and furnishes an element to which conveyors 14 or other machinery within the oven may be secured and supported. Such an arrangement of supporting the machinery within the oven is advantageous as the usual method of securing the same to the panels causes buckling and distortion of the panels unless special structural elements are built into the panels, which latter increases the cost.

In assembly the posts 7 are erected and bolted to the base 13 as shown in Figure 1, and the panels 1 are slid down between the posts 7, the side of each panel 1 covering half of the post so that the edges of each panel abut the edges of the adjacent panel.

It will thus be seen that the posts 7 oper- "ate as an interlocking element as well as a supporting element and of course as it is filled with heat insulating material also has the same function as the panel 1 in retaining the heat within the oven. In an oven of tiers of panels 1 horizontal posts 7 are inserted between the rows of panels 1, that is, at the top of the lower panel 1 and the bottom of the upper panel 1. When it is desired to build any oven of several tiers of panels 1 the vertical posts 7 extend throughout the height of the tiers and lend the required strength and rigidity to the structure. The horizontal posts form the interlocking means to prevent buckling and furnish a proper bearing surface for the panel 1 above. It will thus be seen that such a structure is adaptable to variation in the design of ovens and that the erection cost is very small in comparison to the structural type of oven. The use of the Z

bar strengthening members

5, 5, in the panels 1 is also of considerable importance not only to render support in compression but also to. furnish sufiicient strength and rigidity so that the edges of the panels 1 will not readily become bent out of shape and thereby permit leakage of heat from within the oven around the posts 7 or leakage of dust into the oven in the same manner to the detriment of the articles under process.

In the case of an oven using only one height of panels 1 the channel space formed by

angles

3, 3, and spacers 4 is filled with heat insulating material retained in place and sealed by sealer strips and angles 12 whilein the case of an oven using tiers of panels 1 the bottom of the bottom row and the top of the top row are likewise packed and sealed.

Variations in details might be made in the construction of the posts and panels and still fall Within the scope of my invention.

It will thus be seen that I have invented a form of oven that can easily be erected or readily disassembled and re-erected and one which will have the proper strength and rigidity although of relatively light weight and which can be manufactured in units for assembly for divers types of ovens and which can be constructed with the minimum of erection labor costs.
