4 Claims.

This invention relates to improvements in selfsealing siding and it more especially includes th 4 features pointed out in the claims.

The purpose of my invention is to provide a siding that is self-aligning and at the same time is also self-sealing; that also secures a freedom from rain following the adjacent contacting faces of the joint between two'boards. It is also a purpose of the invention to reduce any tendencies toward opening the joints when the boards shrink. In addition a greater rigidity of board is secured and the usual thin edges are eliminated.

With these and related purposes in view,- I show in the accompanying drawing such instances of adaptation as will disclose the broad underlying features of the invention without limiting myself to the specific details instanced thereon and described herein.

Fig. 1 is an end elevation of a pair of six inch boards in their assembled relation, approximately full size on the original drawing.

Fig. 2 is an end view of ordinary beveled siding applied to ship-lap sheathing.

Fig. 3 is an end elevation in section on an enlarged scale of a modification of Fig. 1 showing the adjacent edges of two boards separated.

In practicing my invention I may use whatever alternatives or equivalents of structure that the exigencies of varying conditions may demand without departing from the broad scope of the invention.

Since insulation and air conditioning has come into vogue there-has not been a corresponding progress in the use of storm-tight siding. It has been found that a single rabbet along the bottom edges of siding boards is not a solution of the problem. Ordinary ship-lap sheathing uses this expedient.

It is customary to nail ship-lap boards against the outside of the studding and then nail the siding boards onto the sheathing. In a majority of instances material economies are and eificiency is secured by omitting the ship-lap, providing that the meeting edges of the siding remain sufficiently tight to seal ofi air currents and at the same time provide rigidity in the boards and dripproof lower edges on each board. It is a trite saying that "a. chain is no stronger than its weakest link. Similarly, the sealing in of the siding of a homeis no greater than the largeness of lower edge of each board is made "drip-proof to prevent moisture collecting at the joint between the adjacent edges of each pair of boards and thus prevent capillary attraction, drawing the moisture into the joint which in time will 5 have a tendency to rat the boards.

In contrast to this common practice with beveled overlapping siding (Fig. 2), I form a single rabbet on the outer surface of a board along its thinner edge and a plurality of rabbets on the inner surface along its thicker and bottom edge. The rabbet along the upper edge is beveled at a different angle than that of the outside and inside surfaces,-whiie along the lower edge a rabbet parallel to the outer face of the board is formed and above it offset by a narrow ledge a second rabbet is made terminating in a second ledge. The angle of this second rabbet is the same as that of the rabbet formed along the upper edge. Thus each board has rabbeted shapes along each edge; onopposite faces.

To accomplish this I form the upper edge 2 of a siding board thinner than the bottom edge 8. At the edge 2 I form a beveled rabbet ll between the extreme upper edge 6 and on the narrow ledge 5. The edge 6 and the ledge 5 constitute selfaligning provisions. The bottom or lower edge I of aboard is formed with double rabbets 8-and i0 and two self-aligning narrow ledges 4. Between the narrow ledges a beveled rabbet Ill, corresponding in angle to the bevel l I, is formed. The extreme lower edge of a siding board is formed .at an acute ascending bevel 9 on the angle IE to form a sharp' drip-01f which prevents rain accumulating against the faces I and 9. The beveled rabbets III and II are formed on an angle I l which is not parallel to the outer surface I of each board. The ledges 4 may be perpendicular to the inner faces 3 as shown in Fig. 3 or to the outer-face I in Fig. 1. The rabbet 8 is parallel to" the outside surface I of the board.

If desired I may secure complete self-sealing by forming any desired shape of grooves and 2B in the beveled faces Iii and H in which any desired type of elastic sealing-in medium may be used.

By making the rabbets i0 and II at an angle to the outside surface I and the inner surface 3 a narrowing of a pair of boards in drying will only open a space between the bevels slightly, not as much as opposite the self-aligning ledges 4 and 6. The boards may be secured to the studs 1 I by nails [6. In Figure 3 at is and I9 is shown the added thickness I secure with my improved siding. In Fig. 1 the outer surface 1, if extended on line l3 of the adjacent upper board it would terminate at l2, the inner corner of the edge 6, thus forming a straight line from the point 24 to the comer I2.

As stated the narrow ledges l and 5 and the edge 6 serve to automatically align the siding boards as they are positioned one above the other before nailing. This feature is not present in the ordinary lapped siding.

An accompanying aesthetic eifect is produced by beveling the bottom edge 9 of the boards upwardly, in that greater depth is secured because of the extra shadow effects present which are not in existence in the usual siding shown in Fig. 2.

An examination of Fig. 2 shows that the lower edges 2! of the boards 22 incline downwardly thus causing gravity to assist in leading water to the joint 23 while in Figs. 1 and 3 the bevel 9 is inclined upwardly. This brings gravity into cooperation to collect the water at the extreme point 24.

As previously stated, there is secured an extra.

thickness at the top edge of a board which adds to its rigidity. This overcomes. any tendency to split boards along this upper edge, as is ordinarily present in beveled siding shown at 20 on Fig. 2.

What I claim is:

1. A siding board comprising an inner straight face, an outer beveled face extending over the rabbets being inclined to the inner and outer surfaces of the boards, a separate rabbet formed along the bottom edge of each board parallel to the outer surface, and means along the bottom edge comprising a drip oil.

3. A self-sealing siding comprising a plurality of cooperating boards secured directly to the studding, such boards having a plurality of rabbets and ledges formed along the bottom edge of each board and a single rabbet and ledge formed along the top edge of each board.

4. A rigid siding board having a relatively thick portion along its thinner edge a relatively thicker portion along its thick edge so shaped that the outer beveled face of one board it continued across an upper board would terminate approximately at the inner upper corner of such upper board, a single beveled rabbet adjacent said corner, and a plurality of rabbets along the thick edge of the board, the related angles of such rabbets being diii'erent.
