SPECIFICATION formingpart of Letters Patent No. 434,507, dated August 19, 1890.

' Application filed November 12,1889. sermno. 330,919. (Nomodelfl To all whom it may concern.-

Be it known that I, ISAAC W. HENDERSON, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Map-Cases, of which the following is a specification, reference being had to the accompanying-drawings, in which Figure 1 is a horizontal longitudinal section, the section being at line 1 of Fig.3. Fig. 2 is a detail, being an elevation of one of the end pieces. Fig. 3 is a section at line 3 of Fig. 1, looking to the right, a part of the map and its roller being cut away so as to expose apart of the inner end of the right-hand end piece. Fig. 4 is a section at line .tof Fig. 1.

Fig.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 andshereinafter described.

That which I claim as new will be pointed out in the claims.

I construct the body of thecase as follows: I take a strip of Manila or other strong paper of suitable width and roll the paper around a roll orformer, 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 formfor example, like that shown in Fig. 5 of the drawingsand 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 thick ness. The metal pieces mentioned donot entirely encircle the roll or former, but there is considerable space between the ends of these metal pieces, as shown in Fig. 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

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, glued, or 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 b can pass.

0 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.

0 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 (1 on D forms aferrule, and the part 2 forms a cover for the end of the body of the case. The piece E 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 h, 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 1' 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 Fig. 4. This end piece 0 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,

. )fd/ I i I 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 0, except that it is provided with a round hole to receive a round stud or pin it on one end of the map-roller.

G are loops hinged to the end pieces Cand 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 case.

The map can be inserted in the case as follows: 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.

\Vhat I claim as new, and desire to secure by Letters Patent, is as follows:

1. A map-case consisting of a tubular body composed of layers of paper cemented together and having the longitudinal slot afor the passage of the map, a cylindrical sheetmetal 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, journaled within said tubular body, substantially as described.

2. In a map-case, the combination, with a tubular body having a longitudinal slot, of

an end piece consisting of two sections, one section enteringinto 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 and forming a surrounding ferrule for the end of the 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 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 (l, forming a ferrule which encircles the end of the tubular body, substantially as described.

4. In a map-case, the combination, with the tubular body, of an end piece consistingof the inner cylindrical section E, insert-ed 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 pin on the map-roller, and the outer section D,secured to the outer end portion of the inner cylindrical sect-ion and provided with an annular flange d, forming a ferrule which encircles the end of the tubular body, substantially as described.
