BRITAIN HOLMES, OF BUFFALO, NEW YORK, ASSIGNOR 'IO HIMSELF AND EDWARD HOLMES, OF SAME PLACE.
MODE OF lNCASiNG KNOTS OR OTHER DEFECTS IN WOOD.
SPECIFICATION forming part of Letters Patent No. 256,567, dated .April 18, 1882.
Applicntion filed October 21, 1881. (No model.)
, lowing is a specification.
The object of my invention is to provide a cheap and reliable means for covering knots or other defects in boards or other material, or in staves, barrels, tanks, or other liquid-holders, so as to make them water-tight. It is particularly useful in sugar-barrels and other packages where the heads or other parts are made of pine, for which clear lumber free of knots has been required heretofore; and the invention consists in forming a shallow open ing around the knot, (either with an incisingtool or with the covering-cap itself, as will be more clearly hereinafter specified,) or forming a depression around and over the face of the knot or other defect, and then inserting a cap or piece of sheet metal corresponding to the shape of the opening, so as to cover the knot or defect with its edge embedded in the wood around the knot, and make a smooth surface, and also form a close water-tight joint around and over the knot, as will be-more clearly hereinafter shown by reference to the drawings, in which Figure 1 is a face view of a barrel-head, illustrating my invention. Fig.2 is a section through line X X, Fig. 1. Fig. 3 is an enlarged section through a board, showing my invention applied thereto. Fig. 4 is an enlarged section, showing a modification of my invention. Fig. 5 is a central section through Fig. 9. Figs. 6, 7, and 8 are sectional views of modifications of my invention, and Fig. 9 represents a top view of one of the metal caps.
In carrying my invention into practice I first make a thin slit or depression, A, around the knotor other defect a, when the metal covering-cap is not heavy enough to allow its rim to be driven directly into the wood, (see Figs. 1 and 2,) which opening is made by an ordinary hollow punch or other incising-tool, when the cap itself is not heavy enough-for the purpose, as above mentioned. A thin metallic cap, 13, having a rim, 0, surrounding it,
(see Fig. 5,) and of the same-form as the opening A, (when such an opening is required,) is then placed in said opening, or on the article, and forced down by a piston or 'a hammer, or other similar means, until the top of thecap lies on or covers the knot or other defect, and the rim is forced tightly into the, wood, thereby forming a close tight joint around the knot or other defect, which joint becomes tighter as the wood becomes wet and swells. It will be ,seen that by this arrangement the wood acts as a packing against the metal at a point in a line surrounding the knot, and more or less below the surface of the wood, and that as the cap is forced down the rim wedges into the wood, and is forced tightly against the outer side of the opening all around the knot, so as to form in said line a perfectly water-tight joint.
- In Fig. 4 I have shown a modification in which the cap-rim G is made to fiareoutward,
as shown in the detached sectional view of a cap, B,in said Fig. 4. E is a depression, into which the said cap is forced into place with sufficient force to bring the rim into the shape of the depression, as shown.
If desired, the cap B may be closely fitted into a depression, E, as shown in Fig. 6, or a cap, F, may be formed,as shown in Figs. 7 and 8, and forced down into said depression, thereby forming a close joint around the knot, it being forced into the position shown by the dotted lines 0, so as to extend the periphery of 8 the cap and tightenthe joint.
In Fig.8 I have shown a nail, f, for holding the cap in place, which device might be used in some cases.
The caps or disks B are usually made of tinplate; but any other suitable metal or material may be used, and the rim 0 may be either round, oval, or of any other desired form to surround the knot or other defect.
I claimas my invention I The combination, with a wooden strip having a knot, of a metallic piece covering the knot'portion, with its edge embedded in the wooden strip around the knot, as and for the purpose set forth.
