ARTHUR H. HALL, OF CHICAGO, ILLINOIS.

MAP-RACK.

SPECIFICATION forming part of LettersvPatent No. 325,337, dated September 1, 1885.

(No modem T 0 @ZZ whom, it 11mg/ concer-11.:

Be it known that I, ARTHUR H. HALL, residing at Chicago, in the count)T of Cook and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in h/Iap-Itacks, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure l is a front elevation, a portion of the door being removed; Fig. 2, a section at line of Fig. l; Fig. 3, a section at line y of Fig. 2. Figs. ft, 5, G, 7. S, 9, and I0 are inodiiications.

My improvement relates to map racks in which the maps or charts are secured at one end to spring rollers, so that the maps or charts can be drawn down for inspection, and then be returned to place by the action of the spring roller. The objects of my improvement are to provide stops arranged so that the lower roller or end of each map or chart will be eX- posed to view when they are all drawn up, so that the name or number of the several maps or charts, .which can be placed upon the lower rollers, will be exposed to View, and to provide a case of improved form for containing a number of maps arranged substantially as shown and described, all of which I accomplish as illustrated in the drawings.

In the drawings, A represents myimproved map rack or case, which consists of end pieces, a, a back, b, a top, c, to the front edge ofwhieh is secured a strip, d, a narrow bottom piece, e, anda door, f, hinged to the front edge of the strip c. This case has considerable width at the top, and is very narrow at the bottom.

g are strips of wood placed one at each end of the map-rack and upon the :inside thereof, as shown in the drawings. Each strip gis provided with a series of notches, l1., equal in number to the number of maps in the case, which notches are arranged so that one end of each of the lower rollers can engage with one o f the notches, as shown in Figs. l and 2.

'i are maps or charts, each of which is secured at one end to a springroller, j, which roller is monntedin brackets upon the inside of the ease, in the usual manner. The lowerend of each map or chart is also provided with a roller, It, as usual, on which lower rollers may be placed the names of the several maps or charts,

or their numbers, as shown in Fig. I. I arrange the maps in the ease substantially as shown in`Fig. 2, the maps not being located in the same plane. I am thus able to arrange a large number of maps in a narrow case. In Fig. I all of the maps are shown drawn up and the door closed. In Fig. 2 the door is open and one of the maps drawn down for inspection. Vhen the maps are drawn up, the lower roller of each map engages with one of the notches h in the pieces g, at each end of the case, whereby such lower rollers will be held in position below each other, so that the name or number of the map will be exposed to View, as shown in Fig. 1.

Z are little strips secured upon each roller, which may be taken hold of to draw down the maps. The strips g may be permanently secured to the sides of the ease, or they may be removably secured thereto.

I prefer to ill the space at each end of the case behind the strip g with a piece of wood,

m, of the thickness of the strip g, so that the exposed surface of the piece m, and the eX-. posed side of the strip g will be in the same plane, which arrangement facilitates the in sertion and removal of the maps. If the pieces m were not used, and the strips g pro jected from the end pieces a of the case, and the brackets which support the maps were placed upon the inside of such end pieces, it would be necessary to remove one of the strips gto insert or remove the maps from the case. W'hen the pieces m are used as described, the roller at the lower end of each map must be a little longer than the one at the upper end.

I do not confine myself to the specific inanner above described of providing stops for the maps. The same result can be acco1nplished in other ways. For example, the strips g, instead of being provided with the notches, might have holes or recesses nin them, as shown in Fig. Il, and the backside of the lower roller of each map might be provided at each end with a little projection, o, entering the holes or recesses n when the map is drawn up.

Another modification is shown in Figs. 6 and 7, in which the strips g are not used at all, but pins p are secured upon the inside of the end pieces, a, while the back side of each IOO end of the lower roller of each map is cut out in a circular form, so as to engage with the pins. In Fig. 8 is shown another modification, in which the pins p are used, and a metal band, r, having a curved plate, s, is secured to the end of each lower roller, the curved plate s engaging with the pin p when the map is drawn up.

In Figs. 9 and lO'Ihave shown still another modification, in which I have provided two pins, q, between which the ends of the roller 7c come when the map is drawn up.

The map rack or case can be secured to a wall in any suitable manner. As shown, it is provided with eyes t, by which it may be hung upon hooks n the wall.

When the maps are not in use, the door of the case can be closed, as shown in Fig. 1. Any one of the maps can then be drawn down for inspection, and when returned to place, the ends' of the lower roller must be brought into engagement with the stops.

I thus provide a compact .ease capable of receiving and holding a number of maps, arranged and held, when drawn up, so that the name or number of each map will be exposed to view, which arrangement will greatly faeilitate their use.

Vhat I claim as new, and desire to secure by Letters Patent, is-

In a map-rack adapted to contain a series of spring actuated map`rollers in different positions, a series of stops located in different longitudinal planes at or near the front edges of the ends of the ease"4 and forming eoncavities or irregular faces for the lower ends of the maps to engage in, substantially as and i'or the purpose described.
