I SIDING CONSTRUCTION Filed Feb. 2, 1953 2 Sheets-Sheet 2 INVENTOR- United States Patent SIDING CONSTRUCTION Lloyd K. Lockwood, Saginaw, Mich. Application February 2, 1953, Serial No. 334,443

22 Claims. (Cl. 189-86) This invention relates to siding or wall covering construction, and more particularly to interlocking sheet metal panels or weather boards, which when assembled in horizontally disposed, partially overlapping relation, constitute the outermost wall or surface of residentialor commercial buildings of all types.

As is well known, there are various types of metal siding panels or weather boards on the market, but these have not been entirely satisfactory in practice, since they are not under tension or are not under a properly controlledtension when assembled in position and are either too loose and create undue rattling and noiseduring wind and rain storms, or are under too great a tension and are dilficult to interlock during assembly.

One of the prime objects of my invention is to design a siding construction wherein the lower exposed, overlapping edge or butt of each panel is held in against the underjacent panel by a predetermined permanent tension which is imparted by'the nails securing the panel in position. The force of this permanent tension is, however, controlled by means other than the pressures exerted by the nails securing either of the panels, thus permitting the provision of suitable uniform hold-in pressures at the joints, which enable both the easy interlocking of the panels and insure a weather-proof joint connection.

A further object of my invention is to provide a siding construction wherein the exposed portions of the panels are under suflicient permanent tension so that they do not rattle in the wind and are relatively immune to the steady vibrations otherwise set up by rain, wind or hail, which cause excessive and annoying noise.

Another object of the invention is to design a siding construction wherein the upper edge of each panel is reinforced and formed to the contour of the overlapping exposed lower edge or butt of the superjacent panel to thus provide a butt of double material thickness which is virtually impossible to dent or otherwise damage.

A further object is to design a substantially concave panel of flexible sheet metal which hugs the backing structure underneath and tends to further flatten out upon the application of pressure so that the weight of a ladder or the like thereagainst will not permanently deform or locally dent or otherwise injure the panels.

A still further object of the invention is to design a siding construction wherein the lower edge of the superjacent panel positively hooks over the upper edge of the panel immediately thereunder and cannot be disengaged, and does so with a clearly audible snap so that the workman is aware that the superjacent panel is in properly aligned position, thus eliminating the employment of chalk lines on a structure which is in horizontal alignment. With this construction, proper alignment no longer depends on the skill of the workmen, and low wage workmen are fully able to apply the siding and are able to do a better job than highly skilled workmen have been doing with older type siding strips.

2,853,163 Patented Sept. 23, 1958 Another object of the invention is to design a siding construction wherein vertical tolerances can be provided in the interlocking arrangement without affecting the tension with which the interlocking portions are held together so that in an older house or building which is out of horizontal alignment, the relative horizontal positions of the siding panels can be adjusted during application to effectively disguise the misaligned condition of the house.

A further object of the invention is to design a weather board or panel of the type described, which is secured by nails which are driven in at approximately a 45 angle, thereby best securing the panel in position against the stresses which are placed upon it, the panel including aligned expansion openings in which the nails are centered to permit the metal panels to freely expand or contract with changes in temperature without buckling. Since the openings provided in the panel are properly vertically and horizontally spaced so that a nail extending therethrough does so at substantially a 45 angle, the workman in the process of nailing, is guided thereby and must nail at approximately the proper angle.

Another object of the invention is to design a flexible sheet metal weather panel, which can be tilted outwardly without becoming disengaged once the lower edge thereof is snapped into position and before the upper edge is nailed to enable the workman to inspect the upper edge of the underjacent panel or the rear face of the tilted panel.

A further object of the invention is to design a panel construction of the type described, wherein the securing or nailing means are protected from the elements, and denting of the nailing flange which is concealed, as by driving nails too deeply, does not affect the appearance of the panels. Further, such denting does not aflect the strength or alignment of the panels and cannot overtension the interlocking portions thereof.

A still further object of the invention is to design flexible sheet metal panels which are easy and economical to manufacture and assemble, and which further can be readily and economically individually replaced in a wall when damaged.

With the above and other objects in view, the present invention consists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportion, and minor details of construction, without departing from the spirit, or sacrificing any of the advantages of the invention.

Fig. 9 is a fragmentary, sectional, end elevational view of the panel construction of Fig. 3 interposed in a wood siding construction in place of one of the wood weather boards, weep openings being provided in the butt thereof and a circulation opening through the backing structure.

Referring now more particularly to the accompanying drawings, the letter S generally indicates the backing structure on which the panels P are horizontally arranged in partially overlapping relation to form the outer. wall or surface of a building. The, immediate structure S to which the panels are applied usually comprises an insulating board of which there are. numerous commercial varieties, but it will be apparent that the panels could be applied to any suitableflat surface or. directly to the studding if desirable. Itis contemplated that the panels are to, be formed of aluminum sheet metal which is flexible, light in weight, and readily cuttable, but the panels could also, of course, be formed of other, suitable sheet metals or materials of similar, desirable properties.

A representative portion of one embodiment of my siding construction is depicted inFi-gs. l and 2, wherein an intermediate panel 10 is shown between an upper panel 11 and a lowermost or starter panel 12. With particular reference to the cross-sectional configuration of these individual panels as illustrated in Fig. 2, each panel 10 or 11' comprises a relatively shallow, concave body portion 13, the upper edge of which is bent obliquely as at 14, and is then turned downwardly and outwardly to form a nail bearing surface 15. The lower portion of the surface 15 is more sharply curved downwardly as at 15a, and the upper edge of the panel is thence directed inwardly as at 16 in a substantially horizontal plane, the portion 16 terminating in an upturned flange 17 adjacent the body 13. The lower edge or butt of the panel substantially conforms to the configuration of the portions 15a and 16, it being turned inwardly as at 18 and terminating in a flange 19 with an obliquely bent hook 2t? formed thereon. As clearly shown in Fig. 2, the butt of each superjacent panel fits over the panel immediately thereunder and is reinforcedthereby, the hook 20 locking over the flange 17; The butt of the panel is directed upwardly at a less sharp angle than the portion 15, however, and for a purpose to be presently described.

I'have found that a nail which is driven at an angle will more firmly secure the panel against the forces to which the panel will be subjected than one which is driven horizontally, and I therefore provide pairs of'vertically spaced, elongatedslots-Zl and 22in the portions 15 and 13 respectively to accommodate the nails 23 which are driven at substantially angles. The slots 21 and 22 are of greater-dimension than the nail shanks 23 to permit the panels to freely expand as a result of outside temperature changes. It will be noted that the slot 21 is substantially rectangular in shape and of limited height to permit the head of the nail to bear on the portion 15, and that the slots 22 are inversely T-shaped to allow for both vertical and horizontal expansion or movement. Since the butt of each panel is directed upwardly at a less acute angle than the nailing surface 15 of the panel therebelow, clearance is left therebetween for the nail heads which will never therefore wrinkle the exposed butt of the superjacent panel. While I prefer to drive nails at an angle, it will be apparent that I could provide slots 21 and 22 in horizontal alignment and drive the nails horizontally if I so desired.

Obviously, the nails 23 will rarely be driven in the same distance with the same amount of force and the force constantly exerted by the nails 23 tending to press in or tension the upper portion of the panel will therefore vary such that in many instances, unless tension controlling means is provided, it might be either extremely difiicult to force the hook 20 up into position, or the interlocking portions will not be tensioned at all. Therefore, I provide a plurality of horizontally spaced strips or spacers 24 of predetermined depth adjacent the slots 21 and 22 which can extend from either the portion 13 or the portion 15, substantially bridging the distance therebetween, and serve the dual purpose of not only controlling the distance which the portion 16 can be pressed inwardly and thereby the interstitial distance between the members 17 and 13, but also of additionally reinforcing the upper portion of the panel and thereby the exposed butt of the superjacent panel so that it is practically impossible to dent or otherwise damage. These spacers 24 are preferably formed when the T-shaped slots 22 are cut in the body of the panel 13, the cut-out portions being bent horizontally to form the spacers 24. Obviously, the spacers 24 could also be similarly formed when the slots 21 are cut in the surface 15 by bending the cut-out portions laterally or could be otherwise provided as desired.

It is very important to note that the panels are so designed that the interlocking portions of the panels are automatically placed under a constant and permanent tension. Thus, the. tensioned flange 17 will snap with an audible click when the flange 19 is pressed up into position so that the workman knows that the particular panel is in horizontally aligned position. The assembly of the instant panels can be very rapid and efficient in most construction, since it is not necessary to adjust the position of each panel with relation to a chalk line. In some old constructions which have settled out of horizontal alignment, it will be desirable to lay the siding according to the chalk lines since the relative position of the panels would need to be adjusted according to the tilt of the structure. The provision of a vertical tolerance between the height of the flanges 17 and 1921s indicated at A in Fig. 5, to permit a slight tilting adjustment of the panels relative to one another, if desirable, in no manner affects the stability of the locking arrangement or slackens the tension on the interlocking portions.

Since often it is necessary to support a ladder or scaffold on. a wall, it is desirable that the panels tend to flatten out or give somewhat without denting or distortingupon application of such a weight, and this flexibility is provided by the slots 22 (see Fig. l) which are disposed along and weaken the inner edge of the portion 14 and permit this portion to flatten out slightly, the upper leg 22a of theslot'being formed in the portion 14. As noted, the body portion 13. of the panels is concaved to hug the backing structure so that relatively little flattening need occur, but it is desirable that the interlocking portions also have some resiliency. When a. weight is placed against a panel, the tendency isalso to pull the panel down slightly, and since the'slots 22 are providedwith the legs 2211, the nailing arrangement is not affected.

The lowermost or starter panel 12 shown in Fig. 2, can be formed from one of the panels previously described, it being only'necessaryto cut'off the lower portion of the panel, or can be separately formed at the factory if desired.

If it should become necessary, it is a very simple matter to replace one of the panels, it being necessary merely to cut across the body portion 13 of the panel, preferably near the lower edge thereof asalong the line B (see Figs. 2 and 5), and to slide-the lower unnailed butt portion edgewise out of engagement with the interlocking portion of the underjacent panel. A new panel is then cut off at or near its upper edge at about the point indicated by the letter C (Figs. 2 and 5), and the butt portion thereof is interlocked with the underjacent panel, the upper edge indicated at Cbeing pushed up between the flange 17 and remaining portion 13 of the replaced panel to firmly secure it in position as shown in Fig. 5.

Various hook arrangements can be employed, and successful panels canbe built which omit the hook 20 as in Fig. 6 without varying the conceptsof the instant invention, since the hook 20 does not in any way have a bearing on the degree of tension which is placed upon the interlocking members.

In Fig. 7, essentially the panel depicted in Fig. 2 is shown, except that the spacers 24 shown in Figs. 1 and 2 are formed by bending the body portion 13 outwardly and thence inwardly in overlapping relation as at 24a to form a continuous spacer instead of bending the cut out portions of the slots 22 inwardly as in Fig. 2. In this panel, the cut-out portions of the slots 22 are, of course, completely punched out.

In Figs. 3 and 4, I have shown other tensioned locking arrangements which may be employed. In Fig. 3, which is similar to Fig. 2, I have shown a starter panel 27, an intermediate panel 28, .and a portion of the superjacent panel 29. With particular reference to the cross-sectional configuration of these panels, each panel 28 or 29 comprises a relatively shallow concave body portion 30, the upper edge of which is bent obliquely as at 31, and is then turned downwardly and outwardly to form a nail bearing surface 32. The lower portion of the surface 32 is more sharply curved downwardly as at 32a and the panel is thence turned inwardly as at 33 in a substantially horizontal plane, the portion 33 terminating in a combination locking and spacing flange which is turned obliquely outwardly as at 34, and thence curves inwardly in a substantially horizontal plane as at 35. In this panel construction, no spacers 24 need be provided, since the depth of the portion 35 controls the interstitial space between the inwardly directed portion 33 and body portion 30 and thereby the interlocking tension. The lower edge or butt of the panel substantially conforms to the configuration of the portions 32a and 33 as before, it being turned inwardly as at 36 and terminating in a beaded flange 37. The upper portion of each panel 32a reinforces the butt of the superjacent panel which curves upwardly at a less angle to provide clearance for the nails 38. Slots 39 and 40, identical to the slots 21 and 22 are formed in the surface 32 and along the inner edge of the obliquely turned portion 31 respectively to accommodate the nails 38 which are driven at substantially 45 angles. Any tendency to displace the portions 35 upwardly when a weight is applied to the butt of a panelis, of course, resisted by the nails 38.

In Fig. 4, I have shown a similar panel in which the obliquely turned portion 31 is eliminated and the nail bearing surface is flat as at 32b. 'Further, instead of a beaded flange 37 on the butt of the panel, a locking flange 41 which curves obliquely outwardly and thence inwardly is provided. This flange 41 which can be readily formed, and which is similarly designed to provide a clearly audible click or snap when it passes between the flange 34 and body portion 30, may be used in place of the beaded flange 37 as desired. This panel has also the nailing slots 3% and 40, of course, and the height of the flange 41 can be less than the height of the flange 3435 to provide a vertical tolerance and permit relative tilting of the panels.

In Fig. 8, aligned weep openings 4242 which are not visible from the outside are provided along the inner terminal edge of the portions 33 and 36 to prevent sweating in the wall of the building. When this particular form is employed, openings 43 are, of course, drilled at spaced intervals in the backing structure between the studding and communication is effected through the vertical portions or legs 40a of the T-slots 40 which are formed in the portion 31.

In Fig. 9, I have shown another modification in which a starter panel 27a and superjacent panel 28a with its interlocking portion cut off is used as a venting panel to replace a clapboard in an existing wood siding construction in which there is difficulty with moisture condensation. In this construction, a starter" panel 27 is provided with horizontally spaced weep openings 44 in the portion 39 and aligned openings 45 are provided in the butt portion 36 of the superjacent panel 28. When this embodiment is employed, openings 43 are, of course,

provided in the backing structure between the studs and tom of the wall with sutficient suitable openings drilled through the backing structure thereadjacent to assure ample air circulation and prevent sweating.

It will thus be seen that I have invented a vastly improved weather board panel which is very practical and oifers many advantages over and obviates many of the practical objections to present panel-s. Obviously, the panels described in this specification could also be used as a covering for roofs of various pitches where desirable.

It is to be understood that various equivalent constructions are to be interpreted as falling within the scope of the claims. For instance the upper edge 14, 15, 16 of each panel could be an independent section or clip mounted on the body portion of any of the panels P in any suitable manner.
