Application filed November 30, 1925. Serial m. 72,156.
'This invention relates to building structures, and more particularly to metal walls or wood structures, \Vith this end in view,
many attempts have been made to firmly join' together adjacent edges of different sheets in such a manner as to conceal them from view, thereby protecting such joints and effectually preventing the entrance of any moisture.
The methods heretofore proposed have not been altogether-successful in that external fasteners were required in securing the sheets.
to the frame-work so as to prevent any lateral movement-therebetween, and in addition It is to be noted that external fasteners are not attractive, nor are the sheets receiving them impervious to the effects of moisture and other natural agencies.
Further, in the metal structures heretofore designed, the intersecting walls terminating in corners were covered by stops which were not uniform in contour and design with the step-shaped walls; consequently, the structure did not present a uniform appearance throughout. I
'One'object of the'present invention is the provision of concealed joints between the adjacent sheets, thereby protecting such joints and eflectually,,preventing the entrance of any moisture.
Another object is to provide means for securing the sheets at their joints to the frame whereby the necessity of external fasteners are avoided.
A further object is to provide cornerstops having the same appearance as the walls so that the structure will present a uniform" appearance throughout.
Other objects and advantages will appear from the following description, of an illustrative embodiment of the present invention.
To more fully, comprehend the invention, reference is directed to the accompanying drawings, wherein Figure 1 is aperspective view of a portion of a house or building having sheet metal walls constructed in accordance with the to disclose a means of sheets together.

Fig. 4 is a perspective view of a segment of an inner corner stopviewin it from a position designated by arrow A in Figure 1.
Fig. 5 is a development of the corner stop shown in Figure 4, the dotted lines desig natingthe lines of fold.
The structure selected for illustration comprises a frame having horizontally disposed angle bars 10 of any standard or appropriate construction to which is applied metal shown in Figure 2, the dotted lines sidings 11 constructed in accordance with the present invention' The angle bars 10 serve as supports for the frame as well as connecting means for the adjoining sheets without necessitating the use of external fasteners.
appearance of a number of weather boards commonly employed in frame structures.
In order to properly and rigidly secure the adjacent sheets to each other as well as to conceal the joint, the uppermostinclin'ed side 12 of each sheet 11 1S bent inwardly and downwardly as at 14 and 15 respectively, thereby-forming a flange, whereas the lowermost ledge 13'of the adjacent sheet 11 terminates in an inclined portion 16 having an extended flange 17 corresponding in shape with the flange 14supra. This flange 14 with its downwardly projecting portion 15 rests on the upper surface of the angle bar 10, and the correspondingly shaped flange 16 of the lower edge of the adjacent sheet is received thereon as apparent from Figure 1. It is to be noted that the-inclined portion 16 which oil'set's the ledge 13 from the plane of the flange 17, conceals the joint from view, thereby protecting it and efl'ecthreaded or plain apertures in the angle bar so that the sheets can be secured to each other and simultaneously anchored to the frame of ,the structure with any suitable fasteners, such as the screws 18. It will be noted that the fasteners employed for this purpose are placed in position from the in sideof the structure, andtherefore the necessity of external fasteners which are subjected to the weather is entirely eliminated. The
fact that the sheets are secured to the-frame at their juncture stiffens them considerably without resorting to the usual practice of nailing. or otherwise securing the sheets thereon from the outside which not only is undesirable, but unsightly andexpcnsive as well.
The angles and meeting edges of the sections are covered in this instance with the corner stops 19 of step shape form similar to and in harmony with the siding associated therewith, so as to present an inexpensive and simple structure without destroying the continuity of the general design:
In this instance the corner stops 19 are formed from a strip of sheet metal of suitable dimensions, a portion of which to the left of the longitudinal center is perforated at spaced intervals corresponding to one segment, to define a triangular opening 19'. The base 20 of the triangular opening 19 coincides with the longitudinal axis 21 upon which the section is longitudinally bent.
However, prior to longitudinal folding, an incision 22 equal to thg altitude of the triangular opening 19' and extending in line therewith normal to the base 20, is made so that the two triangular flaps 23 and 24, corresponding in size and shape to the opening 19, can be folded inwardly about the lines 25 and 26 respectively. It will be observed that angle 20 of the triangular opening 19' determines the slope of the succes sive inclined sides 19, and in view thereof it is a very simple matter to construct the corner stops to conform exactly with the siding to which it is attached.
The opposite edges 27 and 28 of each segment 19 are struck outwardly'and inwardly about lines 29 and 30 respectively,to form the parallel horizontal ledges 31 and 32 which are perforated -at spaced points as at 33.
The strip consisting of a succession of inclined faces defining Z-shaped segments "is then longitudinally bent about its center axis 21 to form the angular step-shape corner stops to conform in design and appearance to the similarly shaped metal siding 11 described above. It will be noted that the longitudinal bending can be readily accomplished with' little effort, in that the metal 34 constituting the connecting material between each section, is comparatively small yet adequate to sustain the segments in an integral relation. To make the corner stops water and weather tight, solder or any other suitable material having adhesive characteristics, is applied to the flaps 23 and 24, thereby rendering the corner covering means a ri' 'd unitary structure, of any desired length. i
The perforations 33 in the horizontal flanges 31 and 32afi'ord means of securing the corner covering strips to the siding'co-w ered thereby without necessitating the use of any securing means on the external surfaces. This feature is' highly desirable, since the water which collects about the screws or other fastening means, will drop off rather than accumulate into a mass which finds its way through the openings in which the fasteners are seated. Obviously other methods 0f securing the corner stops to. the siding may be resorted to for the above disclosed method is -only a preferred embodiment selected primarily for illustrative purposes. I 4 Y I The form of corner stop described above is only applicable to external corners, and since structures often are rovided with walls extending outwardly rom the main portion as illustrated in Figure 1, the junctionof such two walls, requires a covering or stop of a form similar to that'shown in. Figures 4 and 5. The segment 35 shown in Figure 4 viewed from a position-designated by arrow A (Figure 1) comprises .a strip of sheet material which is slit for the most pa'rtalong the central longitudinal axis 36 except at 37 and 38 (Figure-5) which portions serve as connecting means between the two sections. An incision 39 extendin normal to they slitted longitudinal central pertion 36 defines a triangular flap 40 therewith which is folded over-along line 42. The opv ,applied to the flaps in order to render the corners water-tight. The slope .of the inclined sides in this instance is equal to and dependent upon the angle defined by the line of fold 42 and the longitudinal axial line 36. i
It is obvious that the. width of the corner covering means is quite immaterial and that 1 it may be so extended in width as .to actually constitute a partial side covering. The corner covering means may also be stamped, pressed, forged or otherwiseshaped intothe desired form. In fact various changes may be made in the embodiment of the invention hereinabove specifically described,
shaped cross-section, the .ad acent edges of each sheet bent inwardly and downwardly to form cooperating flanges adapted to be supported by and secured to an angle bar constituting a portion ofthe frame so as to provide a concealed joint, and corner stops shaped similarly to the sheets comprising the siding and secured thereto to present a closure therefor.
