A TYURNEYS Patented June '27, 1933 FFECE Lo UIs' H. ROW-LAND, on CINCINNATI, onio connnsronnnncn UNIT Application filedluly 11,

My invention relates to correspondence units and'particularly to means for facilitating the filing and removal of papers therefrom and to means permitting the units to be built up into stacks or tiers.

Correspondence units of this type previously constructed have been so designed as to make it diflicult for papers to be removed with facility or have provided no means for preventing papers from becoming blown from the unit.

The principal object of my invention is to providea correspondence unit in which papers may be filed without chance of their becoming blown out of the unit and in which meansare provided for facilitating removal of one or more of the papers.

Another object of my invention is to provide such a unit which is so constructed as to permit several of these units to be secured one uponthe other where greater amount of filing space is required.

Another object of my invention isto accomplish these new features without any 5 greater cost than is required in constructing other similar units without these advantages.

In the particular embodiment of my invention selected for illustration:

Figure 1 is a top planview of one of these units,

Fig. 2 is a front elevation,

Fig. '3 is a plan of the blank from which i one of the units ismade,

Fig. 4 is a front elevation of two of the units secured together in one manner,

Fig. 5 is an elevation of several of the units secured together in another manner,

Fig. 6 is a detail of one of the spacers and the means for securing the units together as shown in Fig. 4, and V Fig. 7 is a detail of the means for securing the units together as shown in Fig. 5.

Referring now to the drawings, each of these units is composed of a bottom member 10, the front part of which extends inward arcuately so that papers may be grasped by the fingers from the front of the unit and removed readily. The unit has side walls 11 and rear wall 12, all of which have the turned over edges or flanges 13 which prevent 1930. Serial no. 467,280.

the papers being blown out of the unit, yet allows the papers to fall by flexure down into the unit when laid thereon. Suitable feet 14, preferably made of rubber or some similar material, prevent the bottom 10 from resting on the desk orother member where the unit is used. 1

. Referring particularly to Figs. 1 and 6, the turned over edges or flanges 13 of the walls and bottom 10 are provided with aligned apertures 15 and 15 respectively. Spacers 16 are fastened in the bottom apertures 15 and are secured by nuts 17 in the flange apertures '15 of alike unit holding two of the correspondence units together.

Referring particularly to Figs. 5 and 7, the units are secured together directly by means of acorn nutsll' and machine screws 18. A suitable top 19 may be provided on top of the highest unit.

- While the invention has been described above in its preferred form, it will be obvious that various changes and modifications maybe made therein without departing from the spirit or scope thereof and it is therefore desired that only such limitations may be imposed thereon as are'ne'cessitated by the prior art or specificallyset forth in the appended claims. i

I claim as my invention and desire to secure by Letters Patent of the United States:

1. As a new and improved article of manu-. facture, a correspondence unit comprising a single sheet bent up at three sides, forming a four sided bottom and three upstanding walls, said walls having their edge parts bent inward with the corner portions of said edge parts lapped at the two meeting corners of the sides.

2. As a new and improved article of manufacture, a correspondence unit comprising a single sheet bent up at three sides, forming a four sided bottom and upstanding walls at opposite'sides and the rear, said walls having their edge parts bent inward'to form flanges with end portions of said flanges lapped at I the two meeting corners of the side and rear walls and having openings, one through each two lapping end portions of the side and rear flanges, and one through the opposite end part of each flange, said bottom having openings substantially vertically aligned with the flange openings, spacing walls and having openings,- one through each two lapping end portions of the side and rear.

flanges, and one through the opposite end part of each side flange,- said bottom having. openingssubstantially vertically aligned with the, flange openings, foot members, one foot member secured in each bottom opening, spacing 7 members, and means whereby said spacing members may flange and bottom openings of two like correbe secured in the respective spondence units.

,4. As a new and improved article of manufacture, a correspondence unit/comprising a single sheet bent up at three sides, forming a four sided bottom and upstanding walls at opposite sides and thereansaid walls having their edge parts bent inward to form flanges to prevent accidental escape of papers from said unit, said Walls being of such height and their flanges thus being so spaced up from thebottom that papers placed on said flanges may fall by fiexure down past the flanges into the unit, the fourth side of said bottom being devoid ofobstr'uction'to such extent as to allow .the papers to be picked up andiremoved freely at said edge, and the walls and their flanges meeting at the rear to prevent wedg ing of the rear corners of the papers between them. a I
