Claims.

This invention relates to insulating siding panels of the brick simulating type disclosed in my prior Patents 2,021,577 and 2,021,578, granted .Nov. 19, 1935.

in asphalt to form a substantially flat granular surface. Spaced rectangular patches of asphalt are then applied to said granular surface in imitation of parallel courses of brick. Following this the granular side of the felt is covered by a layer of brick colored granular particles to which pressure is applied so that the brick colored particles deposited on the previously applied asphalt patches are partially embedded therein to provide the brick simulating elements of the pattern. The brick colored particles deposited on the portions of the foundation layer lying between the asphalt patches eventually fall away or are removed so that such portions of the foundation layer are exposed between the brick simulating areas in the form of narrow strips representing conventional horizontal and vertical mortar joints. The wide strip of felt is then cut longitudinally and transversely into smaller sections of suitable length and width, each section being wide enough to include several parallel courses of the brick simulating areas. Each smaller section of the felt is then attached to a relatively thick and stiff fibrous base by means of an interposed layer or film of asphalt or similar cementing substance. In order to assure proper bonding of the felt sheet to the associated base this assembly is subjected to pressure in a press having flat upper and lower platens.

The present invention provides improvements in the foregoing method of manufacture which result in the production of brick simulating siding panels in which the mortar and brick simulating areas of the granular surface are more clearly and sharply defined to provide a better imitation of a brick wall. The appearance of brick simulating siding panels produced in accordance with proved method of manufacture provided in accordance with the present invention is that it tends to prevent undesirable flowing or displacement of the asphalt layer by which the granular surfaced felt sheet is united with the fibrous base during the previously mentioned pressing operation.

During the pressing operation described in my prior patents the pressure of the lower fiat platen is exerted only against the brick colored areas of the granular surface pattern since these areas project above the intervening mortar colored areas. This results in an undesirable flowing or displacement of the asphalt by which the granular felt sheet is cemented to the fibrous base. What actually happens is'that some of the asphalt beneath the portions of the covering sheet underlying the brick simulatihg areas is displaced toward the portions of the felt underlying the adjacent mortar joint simulating areas. The resulting bulging of the felt at the exposed mortar' joint simulating areas of the surface pattern tends to impair, to some extent, the appearance and other qualities of the finished product. Another objection arising from the fact that the flat lower platen acts only against the raised brick colored areas of the granular surface pattern is that the granular particles of these areas are embedded more deeply in the underlying asphalt. This diminishes the extent to which the brick simulating areas project above the mortar joint simulating areas and detracts from the appearance of the finished product. The pressure of the lower platen also tends to produce some undesirable lateral spreading of the granular particles comprising the brick colored areas to which said pressure is applied.

According to one feature of the present invention the pressure exerted against the granular surface of the covering sheet during the pressing operation is applied simultaneously to both the brick and mortar colored areas in such manner as to effectively prevent flow or displacement of asphalt from beneath the portions of the felt covering strip carrying the brick colored areas toward adjacent portions of the felt covering sheet carrying the mortar joint simulating areas. Simultaneous application of pressure to both the brick and mortar colored areas of the granular surface pattern also ensures that the original projection of the brick colored areas above the mortar colored areas of the granular surface pattern will not be diminished by the pressing operation. As a matter of fact, according to the preferred embodiment of the invention the'simultaneous application of pressure to both the brick colored and mortar colored areas of the granular surface pattern is effected in such manner as to actually increase the extent to which the brick colored areas are elevated above the mortar colored areas.

Another feature of the invention resides in the provision of a brick simulating. siding panel which is of improved appearance in that the edges of the brick colored areas are evenly and sharply defined as compared with the somewhat ragged edges characteristic of similar siding produced in accordance with my prior patents. This result is achieved by subjecting the panel assem-- bly, comprising the base and the granular surfaced felt covering sheet, to pressure between a pair of platens one of which is provided with fiat faces adapted to bear against the brick colored granular areas of the felt sheet and with rib-like projections adapted to fit between said brick colored areas and to bear against the intervening mortar colored areas of the granular surface, said ribs serving to trim and even 03 the corners and edges of the brick colored areas as they are forced toward the intervening mortar colored areas against which they bear during the final stage of the pressing operation.-

Another feature of the invention resides in providing the fibrous base of the panel with preformed grooves into which all or certain of those portions of the felt which lie beneath the mortar joint simulating areas ofthe granular surface pattern are depressed by the ribbed platen during the aforesaid pressing operation so that all the brick colored areas are thereby brought into greater relief than is possible with the method described in my prior patents.

Proceeding now to a more detailed description reference will be had to the accompanying drawings, wherein- Fig. 1 is a view showing two siding panels produced in accordance with this invention as they appear in disassembled relation.

In Figs. 1, 2 and 3 I have shown two siding panels designated A and B. Each panelcomprises a base 5; a covering sheet, 6 adhesively. united to theouter or weather side of the base and aweather resistant surface 1 composed of granular particles embedded in asphalt at. the outer side of said sheet. r

. it comprises a body of compressed paper; wood pulp, asbestos or other fibrous material commonly employed in the manufacture of products known to the trade as wall board or insulating board. The fibrous mass of the base may be of a homogeneous character or may consist of a plurality of separate layers bonded together by asphalt or any suitable cementing agent usually employed in the manufacture of laminated fibre board. The fibrous material, or the different layers of fibrous material, may also be rendered water resistant by treatment with any suitable waterproofing agents. As shown more particularly in Figs. 3, 4 and 5, the weather side of the base is provided with a preformed brick wall design consisting of the raised brick simulating areas l0 and the lower longitudinally and transversely extending mortar joint simulating areas II and [2. This result may be achieved in several ways. In the construction shown in Fig. 5, the weather side of the base is provided (by either a routing or molding operation) with longitudinally extending grooves or recesses l3 and intersecting transversely extending grooves or recesses H. In this case the mortar-joint simulating areas II and [2 are formed, respectively, by the bottom walls of the grooves or recesses l3 and M. The same effect may also be obtained by initially making the base with a flat weather side and then applying thereto a plurality of separately formed slabs to provide the spaced brick simulating areas Ill.

The covering sheet 6 of each panel is made of roofing felt or other porous fibrous material saturated or impregnated with a waterproofing, compound such as tar, pitch or asphalt. The granular surface I is applied to the outer surface of the sheet in two layers. The bottom or foundation layer is composed of mortar colored granules and is continuous over the entire outer side of the sheet. A second discontinuous layer of brick colored granules is then superimposed on the foundation layer to provide a plurality of courses of brick simulating areas lb. The brick simulatingareas lb are spaced apart so that narrow portions of the foundation layer are exposed therebetween to provide the horizontal and vertical mortar joint simulating areas respectively indicated at 10 and Id. This method of applying the component layers of the granular surface I is more fully and completely described in my prior U. S. Patent 2.021.577. ranted Nov. 19. 1935.

The component parts of each panel are preferably assembled in the following manner: The granular surfaced covering sheet 6 is laid on the weather side of'the base 5 so that the brick colored areas lb of the granular surface 1 lie directly above the raised brick simulating areas H] of the base. If the covering sheet is properly applied the horizontal and vertical mortar simulating areas lc and 1d of the granular surface I will lie directly above and in registry with the and Id they serve to trim and even off the defining edges of the brick simulating areas 1d. During the final stage of the pressing operation the portions of the felt covering sheet underlying the joint simulating areas 10 and Id are forced into the base grooves or recesses l3 and M as shown in Figs. 3 and 4.

In order to provide watertight joints between the horizontal meeting edges of panels contained in adjacent courses the upper and lower edges of each panel are constructed as shown in Fig. 3. As here shown the uppermost recess i3 of base 5 is approximately twice the width of the remaining grooves 01' recesses l3. Similarly, the width of the mortar joint simulating area 1c which is depressed into said uppermost groove H is approximately twice the width of the remaining joint simulating areas of the felt covering 6. At its inner side the upper edges of base 5 is shaped or cut away to provide a recess 16. In effect, the opposed recesses l4 and I6 provide, at the upper edge of the base, a tongue ll having its outer surface completely covered by the uppermost mortar joint simulating area lc of the felt covering. It will be noted that the length of the tongue I1 is equal to approximately one-half the width of recess [4. Immediately adjacent its lower edge the outer surface of the base is shaped or cut to provide a tongue portion i8 projecting below the main body of the base to form the inner wall of a tongue receiving groove I9, the outer wall of which is formed by the opposing lower edge portion 6a of the felt covering sheet 6. With the panels A and B assembled as shown in Fig. 3 it will be noted that tongue I! of panel B is fitted in groove H of panel A so that the felt covering of said tongue is overlapped by the lower portion 6a of the felt covering of panel A. As clearly shown in Fig. 3, the lower edge of the felt covering of each panel terminates in the same horizontal plane as the tongue '8 so that only a portion of the relatively wide mortar joint simulating area 10 at the upper edge of each panel is overlapped by the covering sheet of the next upper panel.

In Fig. '7, I have shown one method oi constructing the ends of each panel to form waterproof vertical joints with the meeting ends of adjacent panels in the same row. As here shown one end of the base of each panel'is undercut at the side remote from the felt covering 6 to provide a recess 20. A tongue extension 2| projecting from the base of the next panel in the same row is fitted in said recess to provide the ship lap joint generally indicated at 22.

Figs. 8 and 9 show a slight modification in which the base member 5 is provided with longitudinally extending grooves l3 but no vertical or transverse grooves H. In this. instance those portions of the felt covering sheet which underlie the horizontal mortar joint simulating areas 1c are depressed into the base grooves l3 while those portions of the covering sheet which underlie the vertical mortar joint simulating areas 1d .are simply cemented to the raised portions of the base lying between the grooves I3. The lower platen employed for pressing together the component parts of the assembly appearing in Fig. 8 must, of course, be designed so that the ribs which bear against the mortar simulating areas 1c during the pressing operation projecting a greater distance'below the fiat face of the platen than the ribs which bear against the transversely extending mortar joint simulating areas 1d. It may be noted in connection with Figs. 8 and 9 that all of the brick simulating areas lb are brought into greater relief by depressing the felt covering sheet into the grooves I: of the fibrous base member.

The horizontal joint construction shown in Fig. 10 may, if desired, be substituted for the joint construction shown in Fig. 3. In this case the upper edge of the base 5 of each panel is shaped to provide a tongue portion 24 which is lapped beneath a similar tongue portion 25 provided at the lower edge of the next upper panel. It will also be noted that, in the construction shown in Fig. 10, th lower edge of the felt covering sheet of the upper panel is projected below the corresponding edge of the associated base and overlaps the upper edge of the felt covering sheet of the lower panel.

In the foregoing I have described what I now conceive to be the preferred embodiments of this invention. However, it will be understood that various modifications may be resorted to within the scope and spirit of the invention as defined by the appended claims.

Instead of using a covering sheet provided with a brick simulating pattern formed by contrastingly colored superposed layers of granular material I may employ a covering sheet having its weather side protected by a single layer of granular material which is substantially uniform in color. In this case the brick simulating effect may be obtained simply by depressing portions of the covering sheet into the preformed grooves in th base to represent the mortar joints, the brick elements being represented by the remaining portions of the covering sheet. By applying sufiicient pressure to the depressed portions of the sheet the surface granules thereof may be almost completely embedded in the asphalt so that these portions of the sheet will have a darker appearance than the remaining or brick element simulating portions. 1
