2,872,265 MULTIPLE UNIT sroRAGE FILE Application May 4, 1956, Serial No. 582,803
Claims. (Cl. 312-407) This invention relates to storage files, and particularly .to those adapted for storing engineering drawings, prints, and other valuable sheets in rolled condition.
Storage of engineering drawings has become a major problem in many industries. it is highly desirable that the drawings be kept in a manner protecting them from tearing, dirt, and abuse generally; yet, they should be readily accessible and conveniently indexed. Also, costs should not be excessive, either in terms of structures utilized or of space allotted for the purpose.
Engineering drawing sheets of reasonable sizes are conveniently kept in cabinet drawers, but, when such reasonable sizes are exceeded, as is often the case in the aircraft manufacturing industry particularly, the only prac tical way to take care of the drawings has been found to be in rolled form. Yet, as rolled drawings are accumulated, it becomes exceedingly inconvenient to keep them available for easy reference and to protect them against damage and deterioration. The customary way is to stack the rolls in any out-of-the-way space. As a result, they are not readily available for use or for reference purposes, and they quickly deteriorate.
According to this invention, a rolled drawing or other valuable sheet may be conveniently placed in a storage receptacle, the interior of which has a closed curve configuration in cross-section, usually circular, and the exterior of which is made up of angularly intersecting, flat sides, thereby enabling a number of the individual storage receptacles to be assembled into a compact self-sustaining stack serving as a multiple unit storage tile.
The present application is a co-ntinuation-in-part of my copending application Serial No. 485,940, filed February 3, 1955, and entitled Multiplex Tube Construction.
A preferred specific form of the invention has a cylindrical interior for the reception of rolled sheets to be stored and an exterior of rectangular right parallelepiped configuration for stacking purposes and structural strength, one end of such receptacle being a door affording access to the interior, and provision being made at that end to accommodate the fingers of a user in the insertion and removal of the rolled sheets. 7
Such storage receptacle is preferably constructed of paper-box-board material by encasing a cylindrical tube within a container of rectangular right parallelepiped configuration. lnner wall faces of the container are tangentially in contact with the outer cylindrical surface of the inner tube, and are adhesively secured thereto.
The container is greater in length than the tubular insert, and is provided with a tight closure at one end and a closure flap or door at the other end. By making the tubular insert of less length than its container at the door end of the storage receptacle, clearance space is provided at the four perimetral corners for insertion of the thumb and forefinger, thereby affording convenient removal of a stored roll from the inner tube.
Because the fiat outer wall faces of these multiplex storage units make it possible to build therefrom substantial stacks which take the place of ordinary filing cabinets, it becomes possible to make use of limited spaces in ofiices or drawing rooms that might otherwise be wasted. Furthermore, the doors or flaps of these storage units provide exposed areas for the application of labels identifying the drawings or other sheets contained in the tubular interiors of the respective units. This enables the adoption of a convenient indexing system in direct and easily viewed conjunction with the stack itself.
The particular form of my invention which I regard as most suitable for general use and which is presently being manufactured comprises an elongate receptacle body made up of an inner tube and an outer container, as above indicated, capped at opposite ends by rigid closures, whose respective outer peripheries conform in configuration with the outer walls of the container and, in effect, provide longitudinal extensions thereof. The inner tube and outer container are preferably fabricated from sheet paper-boxbo-ard in customary manner, the latter being folded about and glued to the former during fabrication. The end closures are preferably metal die castings, although they may be produced in any suitable manner from various other materials, for example, a plastic.
Such end closures are provided with locking formations at opposite lateral sides thereof, conveniently dovetails, enabling two or more of the storage receptacles to be interlocked side-by-side, with their respective opposite ends closely engaged to give the appearance of integral structure, but with adjoining lateral sides of their respective receptacle body portions spaced slightly apart to permit the insertion of vertical tie plates therebetween, if desired.
Ordinarily, one of such end closures is formed as a permanent closure, while the other is provided with a door and with an interior that accommodates the fingers of a user inthe insertion and removal of the rolled sheets relative to the inner tube of the receptacle body. Both end closures could, of course, be of the latter type in instances where access from both ends of the receptacle is desirable.
. Advantages of the rigid end closure caps of this presently preferred form of the invention include positive and rigid interlocking of the individual storage receptacle units in multiple, added structural strength and stability for the resulting multiple unit storage .file, a more finished and attractive appearance, and the provision of a funnelshaped entry way to the inner storage tube, thereby making for easier insertion of the rolled sheets.
From the foregoing, it can be seen that the principal object of the invention is to provide for safe storage of drawings and other valuable sheets in an economical manner affording the use of a simple visual type of indexing system associated directly with the respective stored sheets.
Such objective is obtained by the provision of a basic storage receptacle unit capable of being interlocked in multiple to form a storage file structure of any desired capacity that may be conveniently erected where found most suitable and added to or diminished to meet requirements. Low. cost is assured by reason of the peculiar construction of the storage receptacle units, whereby paperboard may be effectively employed as the material for all or the greater part of each unit.
Further objects and features of the invention will become apparent from the following detailed description of the presently preferred embodiment illustrated in the accompanying drawings.

Referring to the drawings:
As mentioned hereinbefore, it is presently preferred to construct the individual storage units of the invention with rigid end caps or closures of metal or other suitable material firmly secured to opposite ends of a storage receptacle body that is fabricated in multiplex formation from paperboard material, such as is commonly employed by the paper box industry. This provides an economical structure of substantial and attractive appearance and makes possible rigid and positive interlocking of the units in multiple.
An individual storage receptacle unit is illustrated in Figs. 14 and 7. As shown, it comprises a storage receptacle body 10 and opposite end caps or closures 11 and 12.
The storage receptacle body 10 is of multiplex formation, being made up of an elongate inner tube ,13 and an elongate outer container both fabricated from paperboard.
The inner tube 13 may be manufactured in any suitable manner, but is preferably a rigid structure of spirally wound paperboard strip, such as is in common use for many purposes, notably, as mailing tubes. The outer container 14 is of right parallelepiped formation having four fiat and elongate walls 14a, each of which contacts inner tube 13 tangentially. It is preferably folded to formation about the inner tube from a suitably scored flat sheet of paperboard, so that the seam line 15 between adjoining edges of the folded sheet extends along the line of tangency of one of the walls 14a with respect to the inner tube.
The walls 14a of the outer container 14 are preferably securely fastened to the inner tube 13, at and along their respective lines of tangency therewith, by means of a permanent-set adhesive such as glue. This provides a very rigid and strong storage receptacle body, having a tubular interior of closed curve configuration in crosssection for the reception of rOlled items to be stored, and having a fiat walled exterior for stacking purposes.
-To provide a finished exterior, a thin sheet 16 of wrapping paper is preferably wrapped around and glued to end caps 11 and 12.
The end caps or closures 11 and 12 are both preferably die castings of a metal such as aluminum, and are configurated for snugly receiving the ends of both the inner tube 13 and the outer container 14 of the receptacle body. Their outer peripheries substantially conform to the periphery of the outer container 14.
The rear cap 11 is a permanent closure for the rear end of the receptacle body. It is of square cup formation, mg a closed bottom 11a and flat peripheral walls 11b. ..ithin and from the four corners of such cup formation extend connector corners 110, Fig. 1, between which snugly fits the rear end of inner tube 13 in its extension as deeply as desired within the cap, usually right up to the wall 11:: thereof, see Fig. 3. Outer container 14 extends over and snugly fits against such connector corners. Both the inner tube and outer container are preferably glued to these connector corners, making a firm and rigid connection therewith.
The front cap 3.2 is equipped with a door 17, and defines an entry or entryway 18 immediately in advance of the tubular interior 19 of the receptacle body 10. It comprises flat peripheral walls 12b corresponding to the walls 11b of the rear cap an intermedite section 12a, and four connector corners 12 corresponding to the connector corners 11c of the rear cap.
it will be noted that the intermediate section 12a makes the front cap 12 deeper than the rear cap 11 and contributes to the defining of entryway 18. It provides fillets 1201, at all four corners interiorly of such front cap 12, which converge from the square forward portion of the entryway as defined by the four peripheral walls 12b, to a circular rear opening 29 as defined by the rear end of intermediate section 11a. Thus, the rearward portion of the interior of front cap 12 converges to merge with the inner walls of inner tube 13, thereby providing a funnel-like arrangement to facilitate the insertion of rolled sheets within the hollow interior of storage receptacle body 19.
Inner tube 13 fits snugly between and against connector corners 12c, and abuts against the rear end of intermediate section 12a, with its inside wall flush with the inner circumference of the circular rear end of the intermediate section, namely, with the circular wall 20-4, Fig. 7, which defines opening 20. In this manner, the transition between entryway and tube interior is smooth and unbroken.
Outer container 14 extends over and snugly fits against both the intermediate section 12a and the connector corners 120. The end cap or closure 12 provides, in effect, a prolongation of such outer container. It will be noted that inner tube 13 stops short of this end of the container to provide the entryway 18 mentioned above.
The door 17 is provided with a pair of rearwardiy projecting hinge lugs 11% that fit within corresponding hinge recesses 21 defined in the forward margin of one of the walls 120, here shown as the bottom wall, and are secured therein for hinged movement by means of pintle pins 22. Accordingly, door 17 may be swung downwardly and upwardly in the opening and re-closing of the receptacle unit. The periphery of such door is preferably rabbeted, as at 17b, and the forward margins of the walls 12b against which it fits correspondingly rabbeted, to insure a close and protective fit when the door is closed. v
A forwardly projecting and upwardly sloping flange 170, which preferably extends across the entire width of the door 17, serves both as a handle for opening and closing the door and as a supporting rest for the door (when open) of the immediately superimposed unit in a multiple arrangement of such units, see Fig. 5.
For the purpose of keeping the door 17 in tightly closed position following any closing thereof, a pair of leaf springs 23 are anchored interiorly of front cap 12, so as to en rance extend over the respective lines of action of the hinge lugs 17a, see especially Figs. 4 and 5. As illustrated, such springs 23 are anchored'in respective receiving pockets -12e formed integrally with front cap 12 and projecting rearwardly'within the two lower connector corners, respectively. The forward ends of such springs project over the respective hinge lugs 17a and bear down upon them resiliently in the closed position of the door.
Respective recesses 24 are provided in the inner wall of the door immediately above the hinge lugs to accommodate the projecting forward ends of the springs 23.
For the purpose of conveniently identifying the contents of the storage receptacle unit in connection with a visual type of indexing system applied directly to a multiple unit storage file, a card-retaining slideway 25 is defined across the outer face of door 17 by means of a pair of mutually spaced and oppositely directed fins 170., which extend across the entire width of such door in artistic and ornamental combination with handle 170.
in order to positively and rigidly interlock, in multiple, the storage receptacle units so far described, interengaging formations are formed integrally with each end cap. This means that the individual units will be tightly locked together at their ends, even though there is no interengagement along their lengths intermediate such ends.
The inter-engaging formations advantageously take the form of dovetail mating parts. As illustrated, the rear and front end caps or closures 11 and 12 are provided with dovetail parts 26 and 27, respectively, on corresponding lateral walls 115 and 1% thereof and with mating dovetail parts 28 and 29 on opposite lateral walls llb and 12b thereof. These parts preferably extend along the greater part of the lengths of the respective walls for the sake of firmness and security of interlock.
It will be noted that any two or more units maybe quickly and easily interlocked in side-by-side relationship, see Fig. 6, by merely sliding one longitudinally relative to the other or others, and that, in this manner, as
many units as desired may be interlocked to form a horizontally extending, side-by-side series of units, wherein the end caps are contiguously interlocked but the receptacle body portions are slightly spaced to provide elongate and narrow slots 3t? extending from end cap to end cap and from top to bottom of the series.
In erecting a multiple'unit storage file, such as that illustrated in Fig. 8, any desired number of horizontal series, indicated-31 in Fig. 8, may be stacked one upon another on any suitable base, as for example that indicated 32.
Any suitable means may be employed to prevent horizontal shiftingof the multiple unit layers 33 of the stack relative to one another. It is convenient, however, to employ either one or the other or both of the arrangements illustrated in Figs. 9-12.
As shown in Fig. 9, elongate sheets or strips 355 are inserted in selected slots 3d, which, it will be realized, are aligned from top to bottom of the stack. Such sheets or strips may be heavy cardboard or any other material having sulficient rigidity and strength for the purpose.
As shown in Figs. ll and 12, the front end caps 153 are utilized for vertical interlocking of the several layers of a stack. For this purpose, such end caps are provided with special slots for receiving locking rods. Thus, vertical slots 34, see Fig. l, are provided through the opposite dovetail formation 27 and 29, respectively, see Fig. 2. When these dovetail formations are interlocked in mating relationship, such slots come into registry, and it is possible to insert locking rods thereinto.
in Figs. 11 and 12, there is shown a series of short locking rods 36 disposed end to end within aligned receiving slots 34 of the several multiple unit layers 3t of the stack of Fig. 8. Each rod 36 crosses a dividing plane between layers and thereby prevents shifting of the one layer relative to the other. A half-length rod (not shown) is used to commence any vertical series of these rods in s the'lowermost layer thereof, so that the next and subsequent full-length rods will be properly disposed across the respective planes between adjoining layers.
In using the storage receptacle units of the invention, a rolled drawing or other rolled sheet to be stored, see 37, Figs. 2 and 7, is inserted within the inner tube 13, a
finger-grip marginal portion 37a being left protruding in the entryway 18 to facilitate removal. It will be noted that the outwardly divergent entryway provides openings 18a at all four of its corners, which openings are disposed between the inner periphery of the tube 13 and outer periphery of the container 14 and permit the insertion of a finger of the user in grasping the protruding end 3711 of the stored drawing 37 during both insertion and removal of such drawing relative to the storage receptacle.
Thus, the entryway 18, with its funnel-like'formation, tends to direct the rolled sheet into the inner tube 13 during insertion of such sheet in the storage receptacle, and, also, facilitates both insertion and removal by accommodating the fingers of a 'user.
in order to prevent, so far 'as possible, the entry of light to the interior of the storage receptacle when the door 17 is closed, it is a feature of'the invention that the forward end of the lower wall of closure cap 12 to which the door is hinged has its lower edge rounded about the hinge axis as a center, see 12 Figs. 1 and 3, and that the lower peripheral edge of the door is concavely rounded in a corresponding manner, see 17;, Fig. 3. Thus, there is a close engagement of overlapping parts when the door is closed. 7 p
In instances whe'rea rolled sheet to be stored is of the same length as or shorter than the inner tube 13, an accordion pleat insert 38, Figs. 2 and 3, is pushed back into the rear end of such inner tube 13, against rear wall 11a, in order to insure against accidental pushing of the stored sheet too far into the tube to provide a protruding end for gripping. The accordion pleat inserts 38 are conveniently furnished a user in transversely perforated sheet form, so that the approximate length of insert desired may be obtained by tearing a portion from said sheet along one of the lines of perforation, see 39, Fig. 3. 4
It will be realized that various visual indexing arrangements found suitable in particular instances may beemployed' by means of index cards (not shown) slipped into the card-receiving slideways 25 of the respective receptacle units.
While it is highly desirable, from the standpoints of both strength and appearance, to'make the storage receptacle body 10 of multiplex formation by utilizing the outer container 14 in combination with'the inner tube 13, it is easily seen that such outer container may be eliminated in this embodiment of the invention in view of the rigid and fiat walled end closure caps. These closure caps, interlocked as described herein, serve effectively to support the loads imposed by a multiple unit arrangement and present a finished exterior at both the front and back of any multiple unit storage file erected therefrom.
Whereas this invention is here illustrated and described with respect to a preferred embodiment thereof, it is to be understood that various changes may be made, within the scope of the claims which here follow, without departing from the essential inventive concepts here disclosed.
