UNITED STATES PATENT o Flc JAY E. WUNDERLICK, OF WATERLOO, IOWA, ASSIGNOB. OF ONE-HALF TO CHARLES 5 HOS'IETLER, OF WATERLOO, IOWA.
EXPANSION JOINT.
Application filed May 17,
Be it known that I, JAY E. WuNDEaLrcK, a citizen of the United States of America, and a resident of Waterloo, Blackhawk County, Iowa, have invented certain new and useful Improvements in Expans on Joints, of which the following is a specification.
My invention relates to improvements in expansion joints in metal structures, particularly to constructionsof a planarlform shape in iron or steel, and the object of my 1mprovement is to produce such a jolnt between abutting edges of plates or like bodies as will permit and be a positive means for permitting expansion or contraction of the plates without injury thereto or to the oint, when these structures are exposed alternately to considerable variations in temperature. My improvement moreover comprehends an improved method for completlng and rendering strong, resistant and imperyious such a joint, whatever may be its destlned place or employment.
With the above objects in view, I have successfully attained the desired results by the structures and by the method which are hereinafter fully described and claimed, and
Will refer to the accompanying illustrative drawings, in which like numerals indicate similar parts throughout the several views.
Fig. 1 isva perspective elevation of parts of two plates whose prepared abutting edges are in juxtaposition preparatory to being united by means of my improved method. Fig. 2 is a like view showing the edges of the plates united to provide my improved expansion joint therebetween. Fig. 3 is a similar elevation of two plates in position to be operated upon, the plates being positioned angularly relative to each other. Fig. 4 is a like view, but showing the completion of the process of forming said expansion joint between them. Figs. 5, 6 and 7 are modifications.
My improved expansion joint in form and use is such as to be suitable for uniting iron or steel plates of ordinary thicknesses. As shown, the joint is made between plates of relatively thin structure. It is therefore particularly adapted for and useful with such applications as iron or steel siding plates for buildings or vehicles, for tanks, containers, and like constructions.
This type of joint may in practice he Specification of Letters Patent.

somewhat varied, as the expansion joint shown is merely illustrative of one kind in this class. The plates 1 and 5 are placed in any desired relative positions. In Figs. 1 and 2 they are shown as being in the same plane, and their abutting edge parts 3 are bent to the same side, and preferably divergent at to afford a grasp to a clamping device during the welding operation. The angle of bending of each plate should be curvillnear as shown at '2 for maximum strength and elasticity. Y i
The terminal edges 3 are then welded together by a flat union, or by an arched union 6, the latter being more elastic and yleldable, therefore more suitable for light plates.
In Figs, 3 and 4. the plates 1 and 5 are positioned at an angle to each other, with the arched joint 6 within the reentrant angle. The joint could be positioned at the salient angle if desired to suit the required conditlons of use.
In either case, it will be seen that a complete union of the .plates is accomplished, and this may be effected by welding in any of the well-known ways, electric or by the oxyacetylene mode. The reversed curves in the joint at 2 and 6 afford scope for expan- S1011 or contraction of the plates, and the joint is impervious to moisture.
In Fig. 5 is displayed a simpler shape of joint, in which the flanges 3 are parallel and joined by spot welding, or fabutted union, but the angles provide some scope for expansion.
In Fig. 6 the edge parts 3 are offset rather flatly and united edgewise'to provide flat joints Where such joints are desired, while in Fig. 7 a like flat joint is shown, in which,
however, the S or reversed curve flanges 3 are united at their edges, the expansion limit being thus increased, while afl'ording requisite flatness to the joined plates. The joined flanges, it will 'be evident, furnish ribbed stiffening members for the plates,
a desirable feature where the plates are in one direction in narrowly spaced relation, narrowly spaced relation, .and an electrical 10 and an electrical welding device applied to welding device applied to both the upset both the upset edges to fuse said edges, bend edges to fuse said edges, bend the fused parts the fused parts toward each other and weld toward each other and weld them together 5 them together into a closed arched joint. into a closed arched joint.
2. The method of formlng an expansion Signed at Waterloo, Iowa, this 8th day 15 joint between car-roofing plates and thelike of May, 1920. positioned to abut edge to edge, wherein the abutted edgesare upset in one direction in JAY E. WUND'ERLIOK.
