claims. (ci. zo`5 This invention relates to a new and improved siding or roofing product ywhich incorporates in its construction insulation against the transmission of heat therethrough and provides' a roofing or siding which is of pleasing appearance, has' long life and which has many other` advantages over roofing or siding such as are now available.

Briefly, roofing or siding as herein disclosed/VM comprise core portions of ber insulating board with the portions thereof which are to be ex posed covered with an asbestoscement-sheet and providing a new and improved product.

It is a particular object of this invention to provide a new and improved form of roofing or siding which has the feature ofv aording resistance to passage of heat therethrough whichis` of rugged construction but which nevertheless is economical to manufacture. It, is still further the object of this invention to provide a product as described lthe surface of which is reproof, which will be long lived, which will be rigid, and which will have many other and further advantages as will be apparent from a consideration of the following specifications. Still further, it is an object of this invention to provide a method for the economical manufacture of the roofing 'or siding product hereof but yet a such process of manufacture which is simple in operation. y In the drawing accompanying this specification: I

Figure 1 is a diagrammatical illustration of a portion of the process of manufacture of the roofing or Asiding hereof with parts of the drawing in section; A

Figure 2 is a schematic view of a step in the vmanufacture of the products hereof with parts shown in section;

Figure 3 is a further schematic view of a still further step in the production of the products hereof with parts thereof shown in section; and

Figure 4 is a sectional view of the siding member at an intermediate vstage of manufacture.

In the drawing accompanying this specification, in the various figures, like numerals will be used to designate like parts.

In the manufacture of the roofing or siding units of this invention there may be prepared In the drawing there is indicated at I2 aformed asbestos-cement sheet, the manufacture of which is readily apparent to those skilled in the art, which step is' not of the essence of the invention hereof. The asbestos-cement sheet I2 as illustrated is a wet sheet taken oif the sheetforming machine and as such is quite soft and susceptible to formation as desired within reasonable limits. The wet asbestos-'cement sheet is for application to the upper horizontal surface of the blanks II) supported in suitable jig II and as the wet sheet is about to be laid on the surfaces of the blanks I0, the wet sheet is divided as illustrated into three parts by rotating knives I3 which sever the sheet I2 so that a separate sheet of the' wet asbestos-cement composition is laid on each roofing blank III. It ,is tp be understood that-the asbestos-cementhet may .be initially formed of a wet sheet for a single roofing blank or as illustrated it may be formed to cover a plurality of roong and be cut as it is being applied according to the foregoing description. f

The roofing blanks I0 will have hadA applied to theirtop surfaces before being put into position, for receiving the asbestos-cement sheet I2 to be applied thereto, a surface coating of a suitable waterproof adhesive which coating will extend around the rounded butt and down around the underside to the base of the rabbet therein.

This adhesive coating indicated at I4 is applied so that the wet asbestos-cement material may be adhered thereto and if desired or if deemed advisableLthe entire blank may have Ibeen or the remainder of the blank may be suitablycoated with a waterproofing, as for example, with a thin coating of asphalt which is indicated at I5.

Now considering a, single blank IIlin its 'jig- II with a severed sheet y I2r of the asbestos-cement'l composition laying on the top surface thereof 1t will be apparent that when the roofing blank is lifted from the jig that a portion of the asbestossuitable fiber insulating board blanks which are shown at III in Figure 1 as mounted in a supporting frame work or jig indicated generally at II, the details of which jig are unimportant excepting that the jig shall be so formed as to properly in the desired spaced relation with .their upper faces in av horizontal plane l I f cement sheet will overhang the edge at the butt thereof and will tend'to sag downwardly as more clearly shown in Figure 2,at I6. The roofing blank with its wet asbestos-cement sheet thereon as described, it is now conveyed to a suitable jig I1 which may be pivoted at I8 and has a stop portion I9 to position the unit on the jig. The

unit will preferably be placed on the jig inra horizontal position and then turned through the angle of degrees to a vertical position where upon there is a tendency for the overhanging portion of the asbestos-cement sheet to further droop or fold over the rounded butt endof blank I Il to take the position alilproxirnatelyasndi'- blank I0.

In order that the wet sheet I2 may be suitably pressed onto blank I there are provided several pressing members, one of which 2I is adapted to be moved up against the overhanging portion 20 of the wet sheet I2to firmly press this portion 20 into the adhesive I4 which is on .theunderside of the roofing blank between the rounded butt end and the base of the rabbet therein. A further pressing member y22 is provided which has a flat portion and an'upper rounded portion indicated at 23, this pressing member 22 being provided with pins 24 extending 'therefrom adapted to operate in cam slots V25 in suitably mounted cam plates 26. Provision is made through a link 21 pivoted at 28 to the pressing member 22 whereby through pivoted connection 29 a plunger 30 may move the pressing member 22 toward and from' the roofing blank.

In the actual shaping of the wet sheet I2 on the yroofing blank I0 and to secure rrr adhesion of the asbestos-cement sheet to the adhesivel I4 on blank I0 the several pressing members 2l and 22 will press `thefportion 20 of sheet I2 firmly into the adhesive on the underside of the roong blank I0 and that pressing member 22 will as it apthough both the product and the method `of manufacture are susceptible tomodification .as will bereadily apparent vto those skilled in the art to which the inventions hereof appertain.

The inventions hereof having been fully described, I claim:

1. A composite siding-and roofing unit comprising a feltedber insulating body blank, the felted ber insulating body blank having a rounded are advanced into contact with the wet sheet I2 v and it 'will be seen that vthe pressing member 2l 35 proaches have a composite motion due to the operation of pins 24 in slots 2S so that in the last portion of the forward stroke of pressing member 22 it will move downwardly as'well as'forwardly so that not onlyv will the flat portion 22 press against the flat portion of the wet sheet I2 but in addition the-rounded'v end 23 will come down against and press vthat portion of wet sheet I2 which extends around the rounded butt of roofing buttl. I,

In accordance with the foregoing it will be readily apparent that.' by subjecting the blank I0 with its wet asbestos-cement sheet thereon to pressing as above described that the entire wet v sheet may be rmly pressed into the adhesive I4 on theblank I0 and brought into intimate'contact therewith, adhered by the adhesive I4.

The pressed roofing unit core I0 and adhered sheet I2 will now be removed from the jig I1 after the several'pressing members 2| and 22 have been retracted and the surfaced 'blank' I0 may then be suitably dried and cured to produce the new and improved product hereof.

In accordance with the foregoing, it Willbe seen that there has been described a new and improved form of roofing unit which has many adv yantages over roong lwhich has heretofore been known and thatthere has been described a simple method of fabricating these roofingV units albutt, an asbestos-cement surfacing sheet ap-v plied to a face of the unit and continuing around the butt and onto the other 'face thereof, and the asbestos-cement surfacing sheet. adhered to the felted ber insulating body blank,l by an adhesive, whereby an 'insulated and surface finished siding and roong unit is formed. v
