SIDING STRUCTURE Filed April 19, 1950 INVENTOR @0852 r Z. See m q. BY p 2 ATTORNEY United States SIDING STRUCTURE Robert L. Siering, New York, N.

Manville Corporation, of New York Y., assignor to Johns- New York, N. Y., a corporation The instant invention relates to siding constructions for buildings, and the like and more particularly to sidings of improved appearance and structural characteristics.

It is now conventional to use relatively thin siding materials, such as asbestos-cement shingles or clapboard. Generally these are laid in overlapping courses in attempted simulation of conventional wooden building materials. Due, however, to the critical difference in thickness between them and wooden shingles or siding, the simulation is poor. That is, the butt lines are not emphasized to the same extent and, in fact, from a relatively short distance the individual units are practically indistinguishable.

The instant invention has for its principal object the provision of a siding structure in which the siding units are made from relatively thin materials but the butt lines are accentuated and deep, shadow efiects are obtained. More particularly an object of the invention is the provision of a siding construction embodying a spacer strip of improved design inserted beneath the butt edges of the siding, shingles or other covering units of an overlapping course to hold the butt edges outwardly from the units of the overlapped course.

Another object of the invention is the provision of a siding structure employing a spacer strip which extends over the upper edges and behind the units of the underlying course. This construction permits the strip to be readily mounted on a previously laid siding course and insures that the spacer strips will remain in position without danger of accidental displacement during the application of the succeeding course.

Another object of the invention is the provision of a spacer strip of the type referred to which will have approximately line contact with the forward face of the overlapped course of units and the rear face of the overlapping course whereby the probability of the shingles chattering on the spacer strips under wind action is greatly minimized or eliminated.

A further object of the invention is the provision of such spacer strip having apertures adjacent the rear faces of the overlapping units to permit drainage of moisture which may seep behind the units or may result from condensation within the wall. The positioning of the drainage openings adjacent the rear face of the overlapping units insures that the moisture will be discharged outwardly of the overlapped units to minimize staining of such units.

My invention will be more fully understood and further objects and advantages will become apparent when reference is made to the more detailed description of a preferred embodiment of the invention which is to follow, and to the accompanying drawings, in which:

Fig. 1 is an elevational view with parts broken away for clearness of illustratiom-disclosing a siding construction embodying the instant invention;

Fig. 2 is a sectional view on an enlarged scale, taken on the line 22 of Fig. 1;

Fig. 3 is a perspective view of a spacer strip employed in the construction of Fig. 1;

Fig. 4 is a perspective view of a modified form of the spacer strip; and,

Fig. 5 is a sectional view similar to Fig. 2 but disclosing the modified form of the spacer strip.

Referring now to the drawings, there is shown a siding structure comprising a base wall 10 to which there is secured a plurality of courses of overlapping covering units 12. In accordance with conventional practice, the base wall 10 may comprise a series of spaced'studs carrying sheathing and an overlying waterproofing layer 16, the exterior covering units 12 being secured to the base wall by nails 18 or other fastening devices.

Covering units 12 may either be individual shingles or elongated siding strips, the latter being illustrated. The instant invention finds its principal field of usefulness, as previously pointed out, in connection with asbestos-cement covering units, and will be particularly described in that connection, although it will be appreciated that it is also applicable to siding structures employing units of other types. Such units, made from a compressed asbestos-cement composition, are, as previously pointed out, relatively thin, their thicknesses ranging from approximately /8" to The units, either in the form of individual shingles or elongated siding strips, are conventionally secured by driving nails through preformed openings adjacent the heads and also adjacent the butts of the units, the latter nailing being referred to as face nailing and illustrated by nails 18, shown in Figs. 1 and 2.

Due to the relative thinness of such units, the butt lines of overlapping courses are not accentuated and the deep shadow effect, presented by the thicker wooden units, is not obtained. In accordance with the instant invention a spacer member, indicated generally at 20, is employed to space the butt edges of overlapping units of a course from the outer face of units of an underlying course, the spacer also serving to close the gap between the units, as clearly illustrated in Fig. l. The spacer thus gives the appearance of thickness to the overlapping units and provides a deep shadow effect similar to that obtained by conventional Wooden sidings.

In the embodiment of Figs. 1, 2 and 3, spacer 20 is folded from a single strip or blank of sheet material into the shape illustrated to provide a flange 22 which extends behind the units of the overlapped course, flange 22 being integrally connected to a forwardly extending arm 24 which overlies the upper edge of the overlapped unit and projects forwardly to contact the overlapping unit and hold it in spaced relationship to the underlying course. An arm 26 extends downwardly and rearwardly from the end of arm 24 and is integrally connected to a downwardly and outwardly extending arm 28. The forward edge of the latter also contacts the overlapping unit and is integrally connected to a rearwardly extending, substantially horizontal arm 30, terminating in a retroverted flange 32 whose terminal edge contacts arm 28. As mentioned above

arms

24 and 30 are proportioned to space the butt edge of the higher course the desired distance from the underlying course.

Apertures or weep holes 34 are provided at the bend or fold line between

arms

24 and 26, and similar apertures or Weep holes 36 are provided in the material at the bend or fold line between

arms

28 and 30. It will be noted that the

apertures

34 and 36 are thus adjacent the points of contact between the spacer member overlapping unit. Suitably these apertures may be formed by drilling holes through the material of the strip on the bend lines prior to the bending operation. The apertures are relatively closely spaced, as illustrated particularly in Fig. 3, and provide passages for moisture, which may be present either as a result of condensation or of leakage and which tends to flow down the inside face of the units. The positioning of the apertures as shown has the additional advantage that it prevents or minimizes the possibility of moisture, dropping from the overlying course, staining the units of the underlying course.

The material of which the spacer strip is made is preferably relatively thin, resilient sheet material, such as galvanized iron, of say, 22 gauge. Copper, aluminum and other such relatively non-corrodible metals may be used.

In laying a wall embodying the instant spacer member, after the first course of siding units is secured by the face nails, one or more of the spacer strips, depending upon the length of the course, is mounted on the upper edge of the applied course in end abutting relationship with their flanges 22 inserted behind the upper edge of the applied course and with their arms 24 extending across and resting on the upper edge of the units of the applied course. The spacer strips are thus held in position against accidental displacement during the application of the next higher course of covering units. The next higher course is then laid by driving face nails 18 through the apertures provided, the nails passing in contact, or substantial contact, with arm 24 and into the base wall structure.

The spacer strip, which is made of relatively thin material, as previously mentioned, resiliently presses the overlapping units outwardly from the wall against the holding action of the nails 18. It will be noted that only line contact between the spacer strip and the forward face of the overlapped unit and the rear face of the overlapping unit is obtained, which reduces or eliminates the probability of chatter under wind action. The characteristics of the spacer strip also eliminate the necessity of head nails as the upper edge of the overlapped unit is resiliently pressed against the base wall structure.

Referring now to Figs. 4 and 5, a minor modification is shown. The spacer strip, indicated in these views by the reference character 38, has the same configuration as spacer strip 20, except that double thickness flanges 4t] and 42 are formed at the fold lines for contact with the overlapping units, the apertures or weep holes 44 and 46 being placed in the flanges adjacent the points of contact with the overlapping units. This construction, though requiring additional bending operations, has the advantage of insuring that the moisture will be confined to a path along the rear face of the overlapping units.

Having thus described my invention in rather full detail, it will be understood that these details need not be strictly adhered to and that various changes and modifications may suggest themselves to one skilled in the art, all falling within the scope of the invention as defined by the subjoined claims.
