ARTHUR H. HALL, OF CHICAGO, ILLINOIS.

MAP-CASE.

SPECIFICATION forming part of Letters Patent No. 3 84,253, dated June 12, 1888.

Application filed June 25, 1887.

To all whom it may concern.-

Beitknown that I, ARTHUR H. HALL, 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 bad to the accompanying drawings, in which- Figure 1 is a front elevation. rear view. Fig. 3 is a detail showing a piece of the hinged cover. Fig. 4 is a section at line or of Fig. 1, looking to the left. Fig. 5 is a section at line 3 of Fig. 1, looking'to the right, the map being removed from the case.

The remaining figures illustrate a modification, Fig. 6 being a front elevation, Fig. 7 an end view, Fig. 8 a section at line as of Fig. 6, looking to the right; and Fig. 9 a section at line 3 of Fig. 6, looking to the left, the map being removed.

My invention relates to that class of mapcases each of which is designed to receive a single map or chart, the map being secured to a spring roller, and the case in use being designed to be hung upon the wall.

The leading object of my invention is to so construct such mapcase that it can be easily. opened for the purpose of inserting a map therein, and for the purpose of removing the map from the case, which I accomplish as illustrated in the drawings, and hereinafter described. That which Iclaim as new will h set forth in the claims.

In the drawings, A represents the map-case, which consists of two end pieces, to which a thin strip of suitable material is secured, and a third hinged piece at the back.

a represents one of the two end pieces. bis the other end piece. The back side of each of these end pieces is straight. The greaterpart of the remaining portion of the end piece is circular.

0 is a thin piece of heavy paperboard or other suitable material, firmly secured to the end pieces, which, as shown, is done by means of screws, which pass through metal bands or strips (1.

e is a hinged back. To each end of this back 6 there is seen red a strip of metal, f, from the upper end of which there projects a pin, 9,

Fig. 2 is a Serial No. 242.501.. (No model.)

7.0 is drawn up into the case, will be closed by the round strip Z, with which the lower edge of the map is provided, as usual.

on is a piece of leather or other material secured to the round piece Z.

The map-roller is provided at one end with a rectangular projecting piece of metal, which enters a corresponding shaped socket in one of the end pieces, and the other end of the maproller is provided with a round projecting pin or stud, as usual.

or is a slot cut on the inside of one of the end pieces of the case, to receive the round pin on the map-roller.

p is a pin, which is designed to hold one end of the map roller in place. This pinp can be withdrawn, so as to allow the projecting pin or stud on' the end of the map-roller to enter the slot at, and then the pin can be pushed to place, as indicated by dotted lines in Fig. 5.

By opening the hinged cover 6 the map can readily be placed in the case. Then the cover 0 can be closed, and the map-case can then be hung upon the wall ready for use.

To bring the map into view, it is to be drawn down the same as a window-curtain or other maps on spring-rollers, and when not in use it can be returned to its place in the case, at which time the opening between a and 6 will be closed by the round piece Z. If it be desired to remove the map from the case for the purpose of inserting another, or for any other purpose, this can readily be done, first removing the map-case from the wall and opening thehinged cover.

In Figs. 6 to 9, inclusive, I have shown a modification, the principle of construction being the same as before described. In this modification the end pieces are round and are made in two parts. Thin pieces of paper-board or other suitable material are properly secured to the divided end pieces. In the figures, 6 to 9, q 1- represent the two halves of one of the end pieces, and s t represent the two halves of the other end piece. A strip, a, of thin suitable material, is properly secured to the two halves r t of the end pieces, and another strip,

r v, is properly secured to the other two halves,

q s, of the end pieces. The two halves r q of one end piece are hinged together by a suitable hinge, a, and the other two halves, ts, of the other end piece are hinged together by a similar hinge, 1). Thus the two halves of the mapcase are hinged together, and one half may be considered as a cover. The two halves of each end piece, when the parts are closed, can be secured together by hooks c. The map and map-roller used with this modified form of case is the same as before described, one end of the map-roller being provided with a rect angular projection to enter a corresponding hole made on the inside of one of the end pieces, and with a round stud at the other end to enter a recess, (2, in one half of the other end piece, the map being inserted when the case is opened, and when the map case is closed the map will be secured in place therein. \Vith this form,which, as will be observed, is

case to the wall, as before described, I provide two brackets, e, which are seen red to the wall, and the ends of the map-case are provided scribed. perfectly round, instead of securing the map- I with rectangular studs which enter slots in the brackets, as indicated in Fig. 7, and thus the map-case will be prevented from turning.

The two edges of the strips u c which are near the front of the map-case are located a little distance from each other, so that there is an open space, h, between them, which space, when the map is closed, will be filled by the round piece Z on the map.

The arrangement of the parts, when the map-case is in position for use, is such that the map can be drawn directly down through the opening h, as indicated in Fig. 8. In the form first described the map draws down'from the back side of the map-roller, as shown in Fig. 4. In the modification the map draws down from the front of the roller, as shown in Fig. 8. By reversing the case the map may be made to draw down from the back side of the roller.

What I claim as new, and desire to secure by Letters Patent, is-- A map-case consisting of end pieces, a covering or front piece, and a hinged back piece forming a door for giving access to the interior of the case for the insertion or removal of a wall-map and its roller, said map-case being provided with fastenings for securing the case when closed, substantially as shown and de- ARTHUR H.
