4 Specification of Letters Patent.

Patented Mar. 22, 1921.

Application led December 26, 1919. Serial No. 347,626.

. up of independently rotatable sections espe- -cially adaptable for use in post offices for routing mail.

The objects of the invention are to provide a rack made up of a plurality of independently rotatable sections, each section comprising a circular case provided with a plurality of radial compartments adjustable in width; to provide means for normally holding each section against rotation and to allow each section to be rotated independently of the other sections and to generally improve and simplify constructions of this character.

With these objects in view the invention consists in the novel construction and arrangement of parts, hereinafter described,

illustrated in the accompanying drawings,'

and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of construction may be made within the scope of the appended claims., without departing from the spirit or sacrilicing any of the advantages of the invention.

The invention thus Set forth in general terms is illustrated in the accompanying drawings forming part hereof, in which- Figure 1 is a plan view of a filing rack embodying the invention, parts being broken away for the purpose of illustration.

Fig. 2 is a side elevation of two units of the rack for the purpose of illustration.

Fig. 3 is a detail perspective view of one of the sections of the standard which carries the brake mechanism.

'Fig 4 is a longitudinal sectional view through the brake mechanism.

Fig. 5 is a detail perspective View of the spring pressed plunger used in the brake mechanism.

A practical embodiment of the invention is disclosed in the accompanying drawings, forming a part of this specification in which similar numerals` of reference indicate corresponding parts throughout the several vlews.

At 1 is shown a table orany other suitable support upon which the rack may be mounted. Screwed or otherwise attached to the table 1s a metal face plate 2 carrying a concentrlc stud 3 which is received into the bearmg socket 4 of a similar face plate 5 attached to the under surface of the lower section 6 of the rack. The -lower section is thus rotatable upon the table or other support upon which it is mounted. Each sectlon of the case comprises the 11pper and lower spaced circular top and bottom walls 7 and 8 respectively which are connected yto ether by means of the hub ort1on 9. Ra ial grooves 10 being '.provlded in the upper and lower members 7 and 8 and communicating with vertical ooves 1 1 .in the hub 9 for the reception of t e partitions 12 by means of which the compartments 13, for the reception of mail or the like are provided. y

The lower section 6 has connected to its upper wall 7 a face plate 2 upon which is rotatably mounted a face late 5 carried by the upper section 14 whic is constructed 1 n the same manner as the lower section and 1s provlded upon its upper face with the face plate 2V for the attachment of another section if desired. It will be noted that the partitions 12 may be placed in any desired grooves 10, thereby providing any desired size of compartment 13 which may be necessary to accommodate the mail for any one patron. The lower section l5 of the standard which carries the brake\mechanism for the sections of the rackis connected to the table by means of screws 16 or the like. The tubular casing 17 is provided with the flange portion 18 and connected by screws 19 and the like to the standard 1 5 and slidably mouilted within the tubular casing 'is the plunger 20 having a collar 21 fixed thereon, a coil sprin plunger tenl ing to normally urge the shoe 23 into engagement with the periphery of the lower wall 8 of the adjacent section of the rack.

'The upper end of the standard section 15 is provided with a socket 24 which receives the boss 25 upon the lower end of the standard 26 a set screw 27 holding said standard l sections in fixed relation. The section 26 22 being located around said' is also provided with a brake mechanism or' the same construction as that carried by the section 15 and is provided in its upper end with a socket 24 arranged to receive the boss 25 of the next higher section.

Although only two sections or the racir are illustrated in the accompanying drawing it is of course understood that any desired number of sections may be added in the same manner, each section being normally held against rotation by means o1z brake mechanism acting thereon and arranged to be moved independently of the other sections. Although the device has been described as beingbest adapted for use as a mail rack for routing mail it will of course be seen that the device is applicable for filing or displaying any character or small articles where it is desired to place the largest number of articles in the smallest space.

-the invention, within t e scope or' the appended claims.


A tiling rack including a lurality of superposed. concentric, inde en ently rota- :able tiling sections, a stan ard parallel to `he axis of the tiling sections and a brake mechanism carried by the standard and enaging the periphery of each filing section, said brake mechanism normally holding each section against rotation independent oi' the other sections and at the saine time al- `lowing each section to be manually rotated independently or' the other section.

2. A tiling rack including a plurality of superposed. independent, rotatable filing sections` a standard parallel to the axis of :he tiling sections comprising a plurality of ietachable sections corresponding to the {il- Lng sections and a brake mechanism carried ov eacn standard section and engaging the periphery of the adjacent filing section.

A tiling rack including a )lurality of superposed concentric indepen cntly rotutable circular tiling sections, a plurality of superposedstandard sections parallel to the ixis or' the iiling sections and a brake mechinisrn carried by each standard section and engaging the periphery of the adjacent fil- ;ng section.

in testimony that I claim the above, I liave hereunto subscribed my name.
