I, WILLIAM ARNOLD COMPTON, Commercial Traveller, residing at Liberty Corner,
Somerset County, New Jersey, U.S.A. do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention consists in an improved construction for such embossing tools as
are used to impress an ornamental surface upon wood, and it consists in the
combination with the embossing surface of cutters applied thereto at certain points,
as hereinafter set forth.
The object of this construction is to sever the fibres of the wood between the
depressed and undepressed parts of the ornamented surface to prevent the rupture
of such fibres which would be produced by pressing the same abruptly downward
without previously cutting them at the required line.
In the drawing, Fig. 1 is an edge view of an embossing roll, Fig. 2 is a transverse
section on line x, x, in Fig. 1, Fig. 3 is a longitudinal section of a similar roll
provided with a convex face, Fig. 4 is a plan of a strip of wood embossed by the
roll shown in Fig. 1, Fig. 5 is a longitudinal section of the same on line y, y, in
Fig. 4, Fig. 6 is a transverse section of the same on line 2, 2, in Fig. 4, and Fig. 7
is a detail.
a is the embossing surface of the roll c raised above the body of the roll so as to
indent the wood when pressed thereon, and rotated by any suitable mechanism;
b is a projecting cutting edge applied around the opposite ends of the raised
surface a, and d are cutting edges applied to the surface of the roller to form an
ornamental outline thereon around a recess e.
Three such recesses, of leaf shape, are shown upon the roller in Fig. 2, and in
addition to the cutters d, cutters are also projected from the bottom of the
recess to form a mid-rib and veins for each leaf.
When such roller is rotated upon a suitable arbor in contact with a piece of
wood, the embossing surface a depresses a strip f along the surface of the wood, as
shown in Fig. 4, while the recesses e operate to leave the wood standing in
ornamental leaf shaped figures e¹, marked by the cutters & with ribs and veins d³.
The cutters b operate to sever the depressed from the undepressed part of the
wood at the margin of the strip f, while the cutters d serve to separate the raised

page_text: parts of the wood in the leaves e¹ from the depressed surface of the strip around
them; the cutters d operating chiefly to ornament the surface of each leaf by the
marks d².
Fig. 7 shows an alternative construction which may be employed in place of
that described above, which consists in a series of projecting points formed as blunt
round studs, adapted to punch a series of minute holes around the margin of
the leaf.
By this construction, I find that the depressed and undepressed surfaces of the
wood may be effectually divided, the fibres thus being ruptured only in minute
groups instead of continuously, as with the knives d, shown in Figs. 1, 2 and 3.
Except such cutters were used, abrupt depressions could not be made in the
surface of the wood without rupturing and splintering the fibres at the edge of such
depressed parts.
Figs. 5 and 6 show the depressed strip f and the elevated margin g at each side
of it, as well as the raised figures e¹ forming the elevated leaves. To ornament the
surface without depressing the edges of the ornamented strip, a roller with convex
face may be used, as shown in Fig. 3, where the picce of wood is shown in section,
as well as the roller, with the cutters impressed in the wood, and the recess in the
embossing surface operating to leave the surface of the wood standing within the
margin of the cutters. The cutters need not be applied to the entire margin of
the embossing surface or of the recess therein, if the configuration of the surface
permits the depression of the wood without rupturing its fibres at any particular
point.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
1st An embossing roller having cutters entirely surrounding the embossing
surface to sever the fibres of the depressed from the undepressed portions of the
wood.
2nd A recess in the embossing surface of the tool, and cutters applied to the
margin of the recess, as and for the purpose set forth.
3rd A recess in the surface of the embossing tool, a cutter around the edge of the
recess, and cutters projected from the bottom of the recess within the margin of the
same for the purpose set forth.
4th In an embossing tool, the combination, with those parts of its surface which
operate to depress the wood, of series of projecting points arranged about the
margin of such raised parts to sever the fibres, substantially as herein shown and
described.
