SPCIFICATION forming part of Inletters Patent No. 241,925, dated May 24, 1881.

Application tiled March 17, 1881. (Model.)

To all whom it may concern Be it known 'that I, WILLIAM C. C ADwELL, of Logan, in the county of Harrison and State of Iowa, have invented a new and useful Improvement in Chart-Racks, ot' which the followin g is a specification.

The object of my invention is the production of a chart-rack to be attached to the wall, to hold for 'convenience in use and for protection when not in use charts and maps, particularly those used in school-rooms for instruction, and one which can be used to expose to view both sides or ends of the charts or maps.

In the accompanying drawings, Figure 1 is a front elevation of my invention. Fig. 2 is a vertical section of the same, taken on the line w a: of Fig. l; and Fig. 3 is a plan view, showing the chart-frame swung ont for reversing the same.

Similar letters of reference indicate corresponding parts.

A represents the frame, which is rectangular in form, and secured to the wall by screws passing through the angle-pieces a a. The chart rack or frame B iksalso rectangular in form, and of such size relative to the stationary frame A as to be inclosed within it, leaving suicient space at the upper and lower sides for the hin ged arms C C to fold between the two frames, as shown in Figs. '1 and 2.

B is a reversible chart-frame, whose arms U C are end-pivoted at c o to the sides of frame and hinged together at c', so that the frame will not swing out from the Xed frame A. Thus the frame B may be turned end for end and again placed within the frame A, pivoted buttons d d beingemployed to secure itin place.

One lateral halt' of the chart-frame B is provided upon both sides with the boards D D, which form a chamber, into which the charts E may be moved to shield them from dust and all danger of mutilation when not in use.

The charts E are hung and move upon the wires e c, which are secured at the upper side of the frame, the charts being provided with suitable hooks, e e', for catching over the wires, and the lower edges of the charts move between the wires hh across the lower side of the case, which correspondin number and position with the wires e e at the top, for the purpose of keeping the charts in place; and the edges ot the charts may have the metal labels n, on which the number ot` the chart may appear, and which furnishes means for drawing themaps or charts out from the chamber.

Thus arranged, any chart in the rack may be readily selected and drawn out from the chamber in full view, and, when desired, the opposite side of the chart can be shown by simply reversing the frame; and by the use ot this rack the charts are not only shielded from dust by being returned to the chamber when not in use, but the wear and mutilation of the charts incident to constant handling in the ordinary way is obviated, and thus valuable charts and maps can belong preserved and are always held in a manner convenient for use.

It is obvious that instead ot attaching the rack to the wall it might be attached to a portable frame that could be removed from any part of the room to another, and not depart from the spirit of my invention.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- In chart-racks, the combination, with the frame A, ofthe rack B, having wires e h, and the hinged arms C C, pivoted at c to the sides ot' both frame and rack, whereby the rack may be swung out from frame A, turned end for end, and again placed within said frame, as described.
