COMPLETE SPECIFICATION.
Metal Bound Boards for Shelves and the like.
I, WILLIAM HERMAN WINSLOW, a Citizen of the United States of America,
residing at No. 366, Carrol Avenue, Chicago, Cook County, Illinois, U.S.A., Gentle-
man, do hereby declare the nature of this invention and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement:
-
My invention relates to a metal bound board designed especially with reference
to use in shelving, as, for instance, in libraries, drug stores and any other place
in which a neat and durable finish is desired. The purpose of the invention is
to enable an attractive and practically indestructible surface to be provided with-
out the use of expensive materials, as is ordinarily necessary in the case of ordinary
wood shelving and also without necessitating a great amount of labor in polishing
the surface of the shelves. To such end the invention consists in a certain com-
bination of novel features which will be described in the preferred form in
connection with the drawing presented herewith and the essential portions thereof
pointed out in the appended claims.
In this drawing, Figure 1 is a perspective of a board designed especially for
use as a library shelf and illustrating one form of my invention; Figure 2 is a
longitudinal horizontal section of said board in line 2-2, of Figure 1; Figure 3
is a transverse section upon a larger scale in line 3--3, of Figure 2; and Figure 4
is a perspective of the joint in the metal covering described below.
Referring to this drawing, A, is a metal covering or envelope which may be
made of a piece tubing, but which I prefer to make by folding sheet metal upon
itself and joining it together in the form of a flattened tube with the ordinary
stove pipe joint shown at a in Figure 4. This tubular envelope is preferably
shaped to the desired cross section of the shelf, here shown as rectangular, and a
filling made of cheap wood or other suitable material is provided, as is seen
at B, B. This filling is divided longitudinally and in a slightly oblique line, h,
to form two wedge-shaped sections in order that after the filling has been inserted
in the envelope it may be expanded until the covering is bound tightly thereon.
The expansion is effected by forcing inward the larger ends of the two sections
and thus wedging them one upon the other.
It is, of course, obvious that considerable modification is possible in the specific
form and arrangement and a great variety of materials may be used. I desire
therefore, not to limit myself to the specific device here shown in any of these
respects.
It should be noticed that the two wedge-shaped sections of the filling are pro-
vided with a tongue and groove joint. I prefer this construction for the reason
that it prevents any lateral displacement of one section upon the other. .
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed. I declare that what I
claim is:-
1.
A metal bound board consisting of a metal covering in the form of a flat-

page_text: tened tube and a filling composed of two or more wedge-shaped sections whereby
the filling may be expanded within the covering by wedging the sections one
upon the other; substantially as described.
2: A metal bound board consisting of a metal covering in the form of a flat-
tened tube and a filling composed of two or more wedge-shaped sections having
a tongue and groove joint whereby the filling may be expanded within the covering
and lateral displacement of one section upon another prevented; substantially as
described.
