.invention aims to provide a .new and improved device for advantageously supportinga map, a picturecarrying sheet, a curtain or the like upon a wall, for instance, .the wall of a .Schoch-oom.v Y

The device'embodies a tra-ck secured tothe wall` -andfihaving `upperwand .lower parallel edges spaced Vfrom said wall, and a Yplurality of slides to engage the track for supporting lthe map, picture-carrying sheet or theflike.

It is one object of the invention to provide novel -co-opelrable construction of track and slides, permitting quickand easy enga-gement Y of said slides with the track. or disengagement therefrom with vequal facility.

The track is formed of sections and it is a further object to provide unique connecting means between said sections which serve also to space the track outwardly from the wall.

A still further .object is to provide novel and advantageous construction vfor the slides.l

With the foregoing in view, the invention resides in the novel Subj ect matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.

In the drawings above fbriefly described., 1l i denotes a horizontal track formedof elongatedv sections/12, each inthe .form of a single i Thus, when fastening screws 116jare passed through the v'aline'd openings 14--15an'd threaded into the or the likeV 17, these screwsattach the track structurerte the wall er otherV support 'and rat .the lsame -time complete connection vof fithetrack sections with rThe lower 'edgeof each track .sectionsl is formed with oneor more notches :such as 18, which notches are instrumental in thev attachment and detachment of slides .hereinand 7),.this biock being preferably 4bound 4 I by astrip 'of-sheet'metal 21, extend-ing around itsedges. The plate 19 Ilies against the rear Y face of the block QOand its upper and lower ends 22-'23 respectively are l bent forwardly andfthen vertically', so that'they clinch around the upper and'l'ower portionsof the block 2O and secure it tothe plate. Theb'ody portion of this plate is provided with two .rearwardly bent lugsQ-of angular ,'form, to slidabaly engagetheupperand lower edge Aportion-s of the track l1 las seen most lclearly-in F ig. 5. Then the lowean'iostof the lugsor fliooksf is opposite one of the notches 18, the entirle slide S may be moved forwardly at `its lower portion' Aand hence the upper lugo-r hook may be liftedfromthe track, permitting quick and easy disengagement .of the entire slide from Y said tra-ck. Similarly, when a slide vis to be engaged with the track, this may be easily done at a notched portion Vof said track, by passing the upper hook or lug 24 over the upper edge portion of the track and then righting the slide so-its lower hook or'lug 24 will pass through the notch 18.

Preferably the upper end of the plate 19 is provided with an'integral tongue 25 which extends forwardly and then upwardly from the slide to 'providea hook.; These hooks of a number of the slides are often instrumental in supporting maps having rings, grommets or the like at their upperends. The blocks 20 of cork or other suitable material, may readily receive thumb tacks, for attaching pictures or other articles in sheetform, tothe i slides S to be suspended by the latter.

The slides S shown in Figs. 9 and l0, are provided with upper. and lowerhooks or lugs 24 to engage the track ll in the same manner as the hooks or lugs 24. These slides embody forwardly projecting arms 26 for disposition at opposite ends of the roller 27 of a roller map 28. Each arm 26 is formed with a slot 29 and with a circular opening 30 shaped to fit the usual flat and round pintles at theV ends of the roller 27, it being understood that the liat pintle at one end of the roller will be received in the slot 29 of one of the arms 26 while the cylindrical pintle at theother end of said roller is thenreceived in the circular opening 30 in the arm 26 of another slide.

Like the slides S, the slides S may be quickly and easily attached and detached and slid into any desired spaced relation. To prevent Y vdisengagement of them from the roller 27 however, set screws 3l are preferably provided to contact with kthe track 11.

.these brackets to supporting map rollers on which the map is rolled eitherk face in or face out, the fiat roller pintle being at one end of the roller in one instance but at the other end thereof in the other instance. In many I schools, there are setsof maps in racks arranged in such way that the maps roll face out, and in the same schools there are maps used on spring roller boards'and the like which roll the other-way, that is face in, in the same manner as most spring roller curtains. The brackets herein disclosed permit the use of maps of either kind.

Excellent results are obtainable from the general construction shown and described and such construction is therefore preferably followed. However, within the scope of the `invention as claimed, minor variations may be made.

I/Ve claim z l. In a sheet suspending means, a block of material into which thumb tacks' may be forced, aplate disposed vertically and contacting with the rearside of said block, means securing said plate vand block'together, and

upper and lower hooks secured to and projecting ,rearwardly from saidplate for engagement with an elevated track.
