Improvements in Map Cases.
I, ISAAC WATTS HENDERSON, residing at 652 West Adams Street, in the City of
Chicago, in the County of Cook and State of Illinois, United States of America, Book
Binder and Map Mounter, do hereby declare the nature of my invention, for
"IMPROVEMENTS IN MAP CASES," and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement, reference
being had to the accompanying drawings, in which :-
Figure 1 is a horizontal longitudinal section, the section being at line 1 of
Figure 3.
Figure 2 is a detail, being an elevation of one of the end pieces.
Figure 3 is a section at line 3 of Figure 1, looking to the right, a part of the
map and its roller being cut away so as to expose a part of the inner end of the right-
hand end piece.
Figure 4 is a section at line 4 of Figure 1.
Figure 5 is a detail, showing one of the metal strengthening pieces used in the body
of the case.
This improvement relates to that class of map cases in which each case is designed
to receive a single map; and its object is to provide a cheap, strong, durable case,
and to provide end pieces of novel construction which serve several purposes; which
I accomplish as illustrated in the drawings and as hereinafter described.
That which I claim as new will be pointed out in the claims.
I construct the body of the case as follows:
I take a strip of Manilla or other strong paper of suitable width, and roll the paper
around a roll or former the diameter of which equals the proposed diameter of the case
to be made, applying glue or other suitable adhesive material to the paper being rolled,
and after the paper has been thus rolled around the former two or three times, or more
if desired, I insert one or more metal pieces of the proper size and form, for example,
like that shown in Figure 5 of the drawings, and continue to roll the paper around
the roll or former until enough has been so rolled to form the body of the case of
desired thickness. The metal pieces mentioned do not entirely encircle the roll or
former, but there is considerable space between the ends of these metal pieces, as shown
in Figure 5. I then cut out a longitudinal strip from one side of the cylinder which
has been formed as described, forming a slot in one side thereof through which the
map.sheet can pass. I then cover the outside of the case so formed and the edges of
the slot and a part or all of the inside of the body of the case, with a piece of canvas,
or other suitable material, secured in place by glue or other adhesive material.
.In the drawings:-
A represents the body of the map case which is formed from a strip of paper rolled
or glued and cemented as above described.
B are strips of metal cylindrical in form, and having an opening on one side, which
strips of metal are inserted between two layers of the paper while it is being rolled
to form the body of the case. As shown, these strips of metal are provided with holes
into which the glue or cement will partially pass and aid in cementing and holding
the pieces of metal in place.
a is a slot in one side of the body of the case through which the map sheet 6 can
pass.
c is a piece of cloth or other suitable material secured by glue or cement to the
outside of the body of the case, which piece of cloth or other material also is lapped
over the edges of the slot a and either partly or entirely covers the inside of the paper
part of the body.of the case.

page_text: C is an end piece, consisting as shown, of two pieces D, E, which two pieces can
be best made from brass, and may be spun or stamped. The part d on D forms a
ferrule, and the part e forms a cover for the end of the body of the case. The piece B
is of such size that it fits the interior of the body of the case and forms a support
therefor. As shown, it is provided with a flange f, which flange is soldered to e. The
piece E is provided with a depression g on one side, opposite to the slot in
the body of the case, which part g, serves the office of a stop for the strip of wood /,
secured to the outer end of the map when the map is wound up within the
case.
The piece E is provided with an oblong hole to receive an angular stud on the
end of the map roller F, which is a spring roller such as is commonly used for the
purpose. The end piece C, may be held in place by means of a pin or screw j, as
shown in Figure 4.
This end piece C, serves several purposes; it forms a ferrule on the outside of
the body of the case, a covering for one end, a support for the interior of the case at
one end and a bracket to receive one of the studs on the map roller, as well as a stop
for one end of the wood strip h.
D' is another end piece which is constructed in the same manner as the end piece C,
except that it is provided with a round hole to receive a round stud or pin k on
one end of the map roller.
G are loops hinged to the end pieces C and D by means of which the map can
be hung up against a wall, or in any other suitable place. The number of strips B
which it is desirable to use varies with the length and size of the body of the case.
These metal pieces are preferably made of steel and greatly strengthen the body of
The map can be inserted in the case as follows:
the case.
One of the end pieces is first to be secured in place; then the map is to be inserted
from the end, and the other end piece is to be inserted and secured. I thus provide
a strong, durable, compact and inexpensive single map case.
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 map case consisting of a tubular paper body having a longitudinal slot for
the passage of the map and a cylindrical sheet metal strip B internally supporting
the paper body along its length and open along one side opposite the slot in the said
body, substantially as described.
2. A map case consisting of a tubular body composed of layers of paper cemented
together and having the longitudinal slot a for the passage of the map, a cylindrical
sheet metal strip B internally supporting the tubular body and open along one side
opposite the said slot, end pieces for the body and a map roller F, journalled within
said tubular body, substantially as described.
3. In a map case, the combination with a tubular body having a longitudinal slot,
of an end piece consisting of two sections, one section entering into and fitting the
interior of the tubular body and serving as a cylindrical support therefor and for one
end of the map roller and the other section secured to the outer end of the cylindrical
inner section forming a surrounding ferrule for the end of the said tubular body,
substantially as described.
4. In a map case, the combination with a tubular body having a longitudinal slot,
of an end piece composed of an inner section E having a lateral flange f at its outer
portion and inserted into and fitting the interior of the tubular body and serving as a
support therefor, and the outer section D secured to the lateral flange on the inner
section and having the annular flange d forming a ferrule which encircles the end of
the tubular body, substantially as described.
5. In a map case, the combination with the tubular body, of an end piece consisting
of the inner cylindrical section E, inserted into and fitting the interior of the body
to support the latter and having its inner end provided with a bearing for a stud or

page_text: pin on the map roller, and the outer section D secured to the outer end portion
of the inner cylindrical section and provided with an annular flange d forming
a ferrule which encircles the end of the tubular body, substantially as described.
