My. present invention relates to a device for filing and storage purposes and more particularly to an improved form of rack such as is used in supporting. tracings, blue-prints and maps in a hangin position.

An object of my invention is to provide a rack adapted to the above use which will not sag under its normal load, and which will be practical, strong, and at the same time occupy a minimum of space.

Other objects and novel features of my invention will appear from the following deqcription taken in connection with the accompanying drawing, in which- Fig. 1 is a'perspective view of a cabinet equipped with a rack in accordance with my invention. i

by the numeral 10. This cabinet10 has doors 11 which, when closed, provide a substantially fireand dust proof enclosure. Ar

life cf the and maps. This arrangement also provides for a greater filing space than is the case where drawers or shelves and ..c like are provided in a cabinet.

. tension rods 13. vlew of have shown a; steel cabinet and have designated the same The applicant, priorto his present inveng tion, has constructed a greatmany filing devices ofv this character by securing the rods 18 to the sides of the cabinet 10, but he has found this method ofsupporting the rbds 13 to be unsuccessful because of his inability to get suliicient rigidity in the cabinet to pre' vent distortion as aresult of the tension necessary to prevent excessive sagging of the. rods 13. He has also found that such a construction puts a strain upon the cabinet which causes it-to become distorted so thatoperation of the doors 11 is interfered with.

In order to overcome these difliculties,the applicant has provided a rack element having the features shown in Fi 3, but not necessarily limited to the precise construction. This rack comprises end members 15 which in the drawing are shown as of channel iron. The end members 15 are spaced apart by compression rods, 16 which have a shoulder bearingagainst the inner side of the channel iron 15 and are riveted in place. Equally spaced and alternately in a line with the compression rods 16 are the aforementioned supportor The rods '13 pass through the web of the channel iron members 15 and have nuts 17 threaded upon their ends so that they can be put under tension. Thecompression rods 16 are of a greater diameter than the tension rods 13 and as the rods 13 are tightened, the rods: 16 will be placed under compression, thus bringing the end channel members 15 into intimate contact with the shoulders upon the rods 16 and as a resultproducing a rigid frame which may be placed onbrackets or cleats in the cabinet 10 like an ordinary shelf, the channel irons 15 resting upon the brackets. With such a construction, it will be seen that my improved rack can be readily placed in or removed from the cabinet without difiicultyand without mutilating the cabinet By arranging the rods 13 and 16 alternately applicant 'is' able to produce amuch lighter frame than would be the case if allthe tension members creased 'uponanyi of the rods 13 without, as a result causin' a loosenin ofthe other'rods.

sion rods.

It should also be noted that the nuts upon the ends of the tension rods 13 are concealed inside the channel of the end members .15 thus producing a straight unobstructed outer edge upon the rack. It should also be noted that no nuts or washers are required inside of the end members 15 so that a maximum of filing space is provided upon the rods 13.

In Fig. 2 of the drawing, I show a modified arrangement of myiinvention. In thismodificationthe rack 12 is suspended from a side wall and the only additional elements .required are a chain 18 and a bracket 19. The bracket 19 has a notch 20 for engaging, one of the tension rods 13 and the chain 18 has a hook 21 which engages another of the tenlhe chain 18 is also provided with a turn-buckle 22 for leveling the rack.

In using my improved rack the prints or maps to be filed are provided with tabs 23, one

of which is shown in Fig. 4. These tabs are of fabric reinforced with cardboard or the like and have one ortwo flaps 24; which carry an adhesive substance 25 on their inner sides. A-

hole 26 is provided in the stiffened portion of the taband a cut 27 is made vertically through the tab from the hole 26. If a print or map is equipped with these tabs it is only necessary to place the cut 27 acent the ten sion red 13 and press it in'place. The rod will then pass through the hole 26' and, as a v holes 26 and cuts 27 can be placed.

In orderto facilitate movement of the map or prints upon the rods 13, the applicant has provided riders or spacers 28 such as is shown in Figs. 5 6. These riders are of hard wood and are provided with notches 29 and 30 which respectively pass over compressionv rods 16 and tension rods The spacers are placed'along the rods 13' at various intervals and when moved along Wlll engage the several tabs and make possible the movement of a great number of maps at one time. By referring to Fig;'6 of the drawing, it will be seen that thenotches 29 are so located that the rider rests upon the rods 16' and the notches 30 are sufliciently large to prevent the rider from touching the rods 13. It will also be noted that the slots 30 on the end of the rider are slightly larger and offset so that if the rider is once snapped into place, it cannot accidentally rise up or become displaced. 1

embodiment thereof,I desire to have it understood that I do not limit myself thereto, but aim in the appended claims to cover all modifications which come within the spirit and scope thereof.

Having thus described my invention, what Iclaim and desire to secure by Letters Patent 1s 7 1. A rack of the character described, com} prising end members, compression members for spacing said end members, tension rods alternately arranged with said end members for receiving a series of sheet supporting clips, said tension rods being more numerous thansaid compression members so that they will serve to support the outer edges of the filed matter engagedby said clips.

2. A rack of the character described comprising end members, compression membersfor spacing said end members, and tension rods extending between said end members from which to suspend matter to be filed, one of said tension rods being disposed forwardly of dthe rack with relation to the compression r0 s.

3. A device of the class described comprising a rack structure, a series of parallel support rods mounted in said rack'for receiving a series of sheet supporting clips, and a riderslidably mounted with relation to the rack, said rider having recesses formed there in embracing said support rods, said recesses being substantially larger than the cross section of said rods to permit of twisting of the rider with relation to the rods.

4. A device of the class described, comprising a rack structure, aseries of parallel support rods mounted in said rack for receiving a series of sheet-supporting clips, and a rider having sliding engagement with said h rack and embracing but not hearing on. said rods at right angles thereto for sliding the sheet clips on the rods.

' 5. A device of the class described, comprising a rackstructure, a series of parallel support rods mounted in said rack for receiving a series of sheet supporting clips and a rider having sliding engagement with said rack and 'embracing but not bearing onsaid rods at right angles-thereto for sliding the sheet clips on the rods, said rider cut away downwardly adjacent the rods for removal of the rider upwardly from the rack.
