MAP-CASE.

Specification of Letters Patent. Patented N 12, 1918,

Application filed June 19, 1917. Serial N0. 175,676.

To all whom it may concern Be it known that I, EDWARD A, WALBY, a citizen of the United States, residing at Millersville, in the county of Sandusky and State of Ohio, have invented certain new and useful Improvements in Map-Cases, of which the following is a specification.

This invention relates to certain new and useful improvements in maps and more particularly in that type of map including a roller having a pictorial web or map wound thereupon, and the object of the invention is to provide a map of this character having a protective casing inclosing the map roller and provided with a slot to permit the necessary manipulation of the map.

Another object of the invention is to provide a slotted map casing having its ends closed by means of caps, which caps are provided with openings to receive pintles formed on the opposite ends of the map roller.

Another object of the invention is to provide a slotted protective casing adapted to inclose a map roller and to provide the map Wound on said roller with means for closing the slot in the casing to prevent the entrance of dust when the map is in a retracted position within the casing.

The above and other objects and advantages of this invention will be in part described and in part understood from the following description of the present preferred embodiment, the same being illustrated in the accompanying drawings in which,

Figure 1 is a complete view of the device ready for use.

Fig. 2 is a cross sectional view.

Fig. 3 is an end view and Fig. 4 is a fragmentary longitudinal sectional View.

The body portion of my improved map casing is preferably constructed from a piece of smooth finished sheet tin, but any other sheet material suitable for the purpose may be used. In constructing the casing the sheet of material is first rolled to provide a substantially tubular casing 1, open at both ends and having its longitudinal edges spaced apart to provide a slot 2 therebetween. These edges are then rolled back from either side of the slot to provide the cylindrical beads 3 and 4 which will not chafe or mar the map as it passes back and forth in the slot 2.

Received thereon, and closing each end of the casing is a cap, consisting of a substantially circular plate 5 provided with a marginal flange 6. Each of the cap plates 5 is provided with a recess 7 alining with a slot formed in the flanged portion thereof. The slot in the flange of each cap is in turn alined with the slot 2 of the casing when the caps are secured in position thereon. The ends of the flange are rolled back to provide the beads 8 which in assembled position are adapted to be slidably received within the beads 3 and 4 of the casing as shown to advantage in Figs. 1 and 3.

Positioned within the casing is a roller 9 upon which is wound a map or other pictorial web 10. The roller 9 is provided at its opposite ends with pintles 11 which project through suitable openings formed in the cap plates 5 and are adapted to be supported on a wall or other support by suitable brackets 12. The free end of the map or web is adapted to be moved in and out of the casing through the slot 2 and has secured to the free edge thereof a strip 13. This strip 13 is preferably made of wood and is of an oval shape in cross section. When the map is entirely wound upon the roller 10 this strip is adapted to be received and clamped between the beads 3 and 4 in order to close the slot 2 thus preventing the entrance into the casing of dust or other foreign matter, and the extreme ends of the strip are adapted to be received in the recesses 7 formed in the cap plates 5.

As more clearly shown in Figs. 2 and 3 the openings in the cap plates through which the roller pintles pass are eccentrically disposed, that is to say they are arranged nearer the front wall of the casing thus causing the casing to have a tendency to revolve in such manner as to bring the head 4 in engagement with the blank side of. the map or web 11 and spacing the bead 3 from the pictorial side thereof, from this, it will be appreciated that the casing is so arranged that there will be no rubbing action on the marked or colored side of the map which in time would ruin the appearance of the same and render the map unfit for use.

The foregoing description and accompanying drawings set forth the detailed construction of the preferred embodiment of my invention but it is to be understood that the invention itself is susceptible of various changes in the construction, arrangement and proportion of the several parts thereof, and I reserve the right to make such changes providing that the same come within the scope of the appended claims without departing from the spirit of the invention.

. I claim z 1. A device as described, including a tubular casing provided with a slot; beads extending along either side of said slot, caps closing the ends of said casing and provided with eccentrically arranged openings positioned nearer the front wall of the casing, a roller mounted in said casing, pintles secured to the ends of said roller and adapted to project through the openings formed in said caps, and a web wound'on said roller.

2. A device as described including a casing provided with a slot, beads extending along opposite sides of said slot, caps closing and adapted to be received within the beads formed in the casing, a roller mounted within said casing, a web wound on said roller,

and a strip secured to the free end of said web, said strip being substantially oval in cross section and adapted to be clamped between the beads formed on saidcasing with its ends received in the recesses formed in said cap Intestimony whereof I afiix my signature in'presence of two witnesses.
