OORP R TION P ILLINOIS APPARATUS FOR MAP DISPLAY Application filed October 7, 1927. Serial No. 224,650.

My invention relates in general to methods and apparatus for conveying information and giving instruction through the medium of maps, charts and the like, and more particularly to a combination moulding strip and suspension clip structure for slidably supporting maps and charts.

An object of the invention is to provide an adjustable mounting for principal maps or 1g display sheets either mounted or unmounted; to provide a mounting for minor or temporary sheets; and to provide means by which the minor or temporary sheets may be definitely secured in proper position relatively to the principal sheets whereby the two sets of sheets may be coordinated and referred to contemporaneously. I Another object of the invention is to pro vide a display map moulding strip.

A further object of the invention is to provide. a novel suspension clip adapted to be slidably and removably mounted upon my novel moulding strip.

In accordance with the general features of my invention, I provide a substantially continuous wall moulding adapted to be cut to convenient lengths, together with a suspen sion device or clip of such a construction as to be reciprocal to the construction or form of the moulding so that it may be readily mounted upon the moulding and secured thereon against accidental displacement.

Other objects and advantages of my construction will more fully appear in the following detail description, taken in connection with the accompanying drawing, which illustrates a single embodiment thereof, and in which:

Figure l is a fragmentary frontelevation of certain suspension elements forming a part of my invention and illustrating it as applied to one of the walls of a room and representing a map suspended therefrom; I Fig. 2 is a fragmentary perspective view of a portion of the moulding strip illustrating the insert therein; I

Fig. 3 is a fragmentary sectional view taken on substantially the line 33 of Fig. 1; Fig. 4 is aperspective view of the suspen= sion cliplooking at it-from the front;

Fig. 5 is a perspective View of the suspension clip looking at it from the rear; and

. Fig. 6 is a view similar to Fig. 3 illustrating the suspension clip as supporting a map mounting of the character disclosed in my copending application, Serial Number 224,651, filed Oct. 7, 1927. It is thought that my novel method of con veying information will be readily understood from a detail description of the apparatuses by which it may be practiced.

Referring now to the drawing in detail, in which like characters of reference denote similar parts throughoutthe several views: Numeral 1 designates generally a channelshaped moulding strip preferably made of thin metal and comprising a base 2 and a pair of laterally extending sides 3-3. Formed integrally with the outer ends of the sides 7 3-3 is a pair of flanges 4c and 5 disposed substantially parallel to the base 2. These flanges extend outwardly and laterally from the sides 33 and project in opposite directions.

The channel defined by the strip 1 is filled by a stiifening'strip or insert 6 which may be of cork, wood or analogous material of proper shape and size to fill the channel of the moulding strip throughout its length. This strip may be secured in place within the channel by means of glue or other cementitious material. The fastening for the in sert 6 is further established by the means provided for securing the strip to the relatively stationary support or wall.

It will be noted from Fig. 3 that the outer surface of the core or insert 6 is disposed slightly below the flanges l and 5. The insert 6 is provided at intervals with holes 7 which are disposed in alignment with holes 7 in the base 2 of the strip. The holes in the insert 6 are preferably countersunk, as shown in Fig. 3. Positioned in each set of the aligned holes 7 and 7 is a tubular eyelet 8 having outwardly flaring edges 9. It will be noted from Fig. 3 that the edges 9 of the eyelet are disposed flush with the flanges 4 and 5 of the strip. A screw 10 of suflicient length to secure the strip to the relatively stationary support is disposed in each eyelet 8. 'Each of these screws is provided with 4 indicated at 18.

an enlarged head 11 seated in the flared portion of the associated eyelet. These screws not only serve as a means of securing the moulding strip 1 to the support or wall but, previously pointed out, at the same time tend to air fastening the core insert 6 to the metallic strip 1.

A. moulding strip thus formed and mounted is provided with movable suspension devices or clips formed to embrace and having slidable movement on the moulding strip. Each of these clips may be made from a blank of thin metal and comprises a body portion 14 and inwardly turned flanges bent back upon the body portion 14 including a top member 15 turned back and downwardly flanged to ride upon the upwardly turned flange ot' the moulding strip, and an upwardly turned flange 16 adapted to engage the downwardly turned flange of the moulding strip.

A hook 17 is turned outwardly from the body portion 14. and is disposed at substantially a. right angle to the portion l i, as Attention is directed to the fact that. the flange 16 comparatively shorter in length than the flange for a purpose which will become more apparent hereinafter. Extending from the body portion 15 adjacent the flange 16 is an oflset member 20 including a downwardly projecting wall fender 21.

The lower flange 5 of the moulding strip is provided with spaced notches 23, each of which is of such a width as to receive the lower and relatively short flange 16 of the suspension clip. It will thus be evident that when the suspension clip is attached by means of its own downwardly turned flange 15 to the upwardly turned flange i of the moulding strip, the flange 16 may enter one of the notches 23 and may be thus readily engaged by lateral movement in either direction with the lower flange 5 of the strip. This arrangement insures against the accidental displacement of the suspension clip relative- 1y to the moulding strip.

After a pair of the suspension clips have been slidably mounted upon the strip 1, they may be spaced a given distance apart so as to accommodate and support a device such as the map 25, shown in Figs. 1 and T his map includes eyelet lugs 26 adapted to be hung on the hooks 17 of the suspension clips. It will be noted that the map stick 28 of the map is adapted to abut the fender plate 21 of each or the suspension clips, as shown in Fig. 3. This tender plate 21. due to its offset position relative to the plane of the body portion ll of the clip, serves to maintain the map away from the wall, thus preventing the map from being soiled by contact therewith. Moreover, should the map he posltioned so as to be drawn down over the front of a blackboard, by my spacing it from the surface of the blackboard, it will follow that any chalk data on the board will not be erased or marred by the rear of the map coming into contact with the board.

In Fig. 6, I have illustrated my novel map supporting structure as supporting a map mounting 30 of the construction disclosed in my co-pending application, Serial Number 224,651, filed Oct. 7, 1927 This mounting as disclosed in my co-pending application comprises a pair of spaced brackets secured to a metallic spacing strip 71. The upper edge of the spacing strip 71 is provided with spaced openings 74 for receiving the hooks 17 of the suspension clips. From the foregoing, it will be readily apparent that not only can my novel suspension clips be utilized to support a map or chart such as the map but they may also be used to support a mounted map unit including a spring shade roller mounting such as indicated at 30, and suspended, as shown in Fig. 6, so that the lower port-ion of the roller mounting will bear against the fender member 26 and hold the spring roller and the dogs thereo'l in operative position.

Now it frequently happens in the use ol" charts and maps that temporary or auxiliary sheets of data are associated with the map so as to aid in the explanation of the same. By providing the moulding strip with insert (5 of cork or other material which will readily receive and firmly hold a thumb tack, these auxiliary sheets of data may be positioned and supported in proximity to the principal sheets or map. In Fig. 1 is illustrated an auxiliary sheet 30 for additional related matter which is positioned adjacent to the map 25 and secured to the cork 6 of the moulding strip by means of thumb tacks 31. Due to the proximity of the map 25 and the sheet 30, it will be evident that they may be studied and visualized together.

Now I desire it understood that, although I have illustrated and described my invention in detail, the invention is not to be thus limited, but only in so far as defined by the scope and spirit of the appended claims.
