This invention relates to improvements in correspondence filing cabinets and similar articles of furniture.
It has been customary for many years to provide sheet metal filing cabinets for filing correspondence, both letter and legal size with the papers arranged in position where they stand on edge in a file drawer. This type of filing has become well standardized in business, the papers usually being inserted in folders and being filed in drawers slidable in and out of the cabinets. These cabinets are usually made in three, four, and five drawer units, the four drawer cabinets being used in substantially greater numbers than the others. These filing cabinets have become standardized in size, for the most part, and the four drawer units usually have an overall height of 51 inches or slightly more.
One of the principal factors involved in the construction of filing cabinets is the saving of space in order to accommodate the greatest number of files in a given amount of floor space due to the high cost of floor space per square foot in urban buisness areas.
Correspondence filing cabinets of the type heretofore used and well known in the art over which the present invention is an improvement are illustrated, for example, by the cabinet structure shown in Patent 1,934,644 patented November 7, 1933.
According to the present invention, improvements have been made in the construction and filing capacity of correspondence filing cabinets of the type heretofore used, as above explained, in which the structural characteristics of the cabinet provide for a well-constructed substantially rigid cabinet in which the capacity has been increased, to the extent that five drawers of correspondence of either letter or legal sizecan be accommodated in a cabinet having an overall height of 51 inches, which was the standard height of cabinet previously used for four drawers. Cabinets made according to the present invention will also accommodate four drawers of correspondence of standard size in the space heretofore used by three drawers.
In addition to the substantial conservation of space in filing of standard size correspondence in the usual manner now employed, the invention provides a cabinet construction having the casing sections constructed to use duplicate parts at the top and bottom and on opposite sides, as well as in the construction of the front frame, to materially reduce the number of differentially constructed parts necessary for building the cabinet and thereby reduce tool, die, and other costs of construction to a substantial extent without sacrificin strength, rigidity and serviceability in the finished cabinet. The cabinet according to the present invention also facilitates modern styling through the use of rounded corners and the elimination of corner joints between the side, back. and front sections. drawer suspension cooperate with the cabinet side wall portions and the frame member for interlocking the several partssin assembled cabinet forming relation in order to facilitate efficient and economical assembly of the cabinet parts. By constructing a cabinet in this manner, it is particularly adaptable for use as a pedestal unit in sheet metal desks, either in legal or letter size in which a four drawer unit is provided by the present invention to use the same space as the previous three drawer unit.
Each front frame section has locating means at opposite sides of each of the parts thereon for attaching a drawer supporting member thereon, one of which is used with the other means on an oppositely positioned section in an assembled frame for locating and supporting a separator in position to define a. drawer opening.
The invention provides a sheet metal filing cabinet having a back-side section formed with an attaching means in the form of an angular flange structure on the forward edges of the side portions having interfitting and interlocking engagement with attaching means in the form of channel portions of front side sections of duplicate construction. The front side sections have front corner sections formed with inwardly curved and return bent flanges embracing the forward edges of the front frame while the drawer supporting members are formed for interlocking engagement with the front frame member at the front end and with the interlocking portions of the front side and back-side members toward the rear portion thereof for detachably interlocking the front frame, the front side sections and the back-side member in rigid assembled cabinet forming relation. Duplicate top and bottom members are then applied to the assembled side and back-side members and rigidly secured thereto for completing the cabinet structure. This provides a cabinet structure and assembly that may be readily formed and assembled in a most convenient and economical manner.

The filing cabinetillustrated in Fig. 1 has a topwall l6, side walls ll, "rear'wall l2, and bottom wall l3. The cabinet has five separate pieces,
as shown in Fig. 2 forming the top, side, bottom:
Short offset flanges H are formed of rear side wall portions I l and rear wall I2 but do not extend into corner sections Hi. The front edge of each rear side wall portion I' l-is formed with an inwardly extending lateral flange l8 terminating in a rearwardly directed flange IS in spaced parallel relation to the-adjacent portion of side wall portion Hi forming arearwardly opening channel alonge'ach forward edge of the backside member. Flange 9 is formed with a plurality of vertically spaced pairs of apertures 28 for receiving interlocking tongues on a case slide as hereinafter described.
The forward portions of sidewalls ii are formed by a pair of identical front side members '4;
2|. Each member 2| is interchangeable for use on either the left or right side of the cabinet by reversing its position so the top end on one side is at the bottom on the other side. Attaching flanges 22 are formed on the top and bottom edges of each front side member 2| and have the same height: and contour as flanges ii. In assembled relation flanges 22 are aligned with flanges H on thesides of the cabinet at the top and bottom edges. Front end sections 23 of curved form are provided on the front portion of each front side wall section 2| and terminate in a rearwardly extending flange 24 forming a rearwardly opening channel. The curved front end sections 23 facilitates more convenient and economical manufacture and also an improved appearance to conform to current style designs.
The rear edge of each front side member 2i is formed with an attaching channel 25 formed by lateral flange ifihaving offset strip 2! at the inner edge thereof extending in parallel relation to side member 2| and terminating in an outwardly extending flange 28; Offset strip 21 is formed with a plurality of-pairs of apertures 29 having the same spaced relation as. apertures for registry therewith. Two front side members 2| are used in each cabinet arranged in reversed position end for end as shown in Fig. 2 so that each member is assembled with the backside member by having flanges l8 and |9 engaged in attaching channels 25. The plurality of pairs of apertures 20 and 29 will register when each flange I9 is engaged in the proper position in each attaching channel 25. Channels and flanges l8 and I9 cooperate to provide a rigid structure along the sides of the cabinet and eliminate the'use of angle bars, channels, and the like which have been heretofore used to provide adequate strength.
A front frame 30 is formed of a pair of duplicate frame sections 3l. Each frame section 3| is formed to provide a vertical side member 32 having laterally extending arm portions 33 on the opposite ends, one of which is relatively short, while the one on the opposite end is of substantially greaterlength. I The lon'ger arm' fl has! its 'dimensionflx'ed so that when it is placed. in 1' end to end abutting relation with a shorter'ar-m 33 ofanotherdup'licate frame section 3| in reversed position, the total length will providethe proper dimension forth'e width of the file cabi net at the front'sothat opposite sid'es H of the cabinet will be 'subst'antially'parallel. Frame sections 3| are-formed with unequal arm portions" 33 on opposite ends in order that the j'oin'tbetween the arms at the top andbottom of the 1 frame in assembled relationas shown inFi'g. 2,1 for example, will be adjacent opposite sides which enables a frame having 'greaterstrength to" be' produced as compared with one where the joints are in the same vertical plane such as in the center.
out vertical side member -32 and arm 'por'tionsivi. Channel 34 has a curved front section 35 formed to have the same shape as the curved portion of front section 23 of front side'membe'r 2| addition to providing substantial strength to the frame structure and -the'finished cabinet 'at the front end. A rigid support is provided for the front of the side members by this frame struc ture. The portion where arms 33 are joined to vertical side member 32 have curved sections formed to have the same curvature as the top and bottom corner portions at the front of the cabinet. In order to provide for the desired curvature of sheet metal in forming the corner sections between vertical side member 32 and arm 33 it has been found desirable to form each portion joining an arm 33 to vertical side member 32 with a bead 34 in the center portion of channel 3 5. Each vertical side member 32 is formed with spaced pairs of apertures 31 in the central channel portion 34, as clearly shown in Figs. 2 and 3, to provide corresponding pairs of apertures to apertures 20 and 29 for receiving interlocking projections or ears on case slide mem bers in a manner that will be described. Chane nel 3 is also formed with a smaller aperture 38 between each pair of apertures 31 and offset slightly from the aligned arrangement of apertures 31 to provide an opening in front frame 39 for receiving an interlocking tongue on the case slide member to be described.
Front frame 3| supports theside, top and bot tom walls of the cabinet to define the front opens ing for receiving the file drawers. Separators 39 in the form of flat bars have return bent portions 40 on opposite ends each formed with a pair of beads 4| in the laterally extending portions for engagement in a pair of apertures 42 formed in horizontal alignment in any one of a plurality of positions in vertical side members. 32. The upper ends of portions 40 are formed to support the drawer supporting members on the frame in cooperation with the means engaging in apertures 31 as hereinafter described. Projections 4| on each separator are engaged in pairs of apertures 42 in the front frame at opposite sides 5 thereof to place it in the desired position for the size of drawer to be used in the cabinet. A pair of apertures 42 is formed in each side member 32 on opposite sides of each pair of apertures 31 in equi-distant relation from apertures 31. One pair of apertures is used in one position of a side member 32 while the other pair is used when the side member is in a, reversed position. Front frame 30 is formed with a sufficient number of sets of apertures as shown, to provide for receiving five correspondence size drawers for standard letter-size sheets and also for receivingtwo half-size drawers in place of each lettersize drawer to adapt the cabinet for use with drawers for receiving index cardsfiled on edge.
Four separators 39 are used where correspondence or letter size drawers are to be mounted in the cabinet to provide for five drawers. The separators for five drawers are positioned in front frame 3|] in the manner shown in Fig. 2. Projections 4| are welded at the outside of channel 34 to vertical side members 32 for cooperation with the side members in forming a rigid vertical frame structure. Separators 39 are assembled in front frame 30 at the time sections 3| are brought together for assembly. This is done by inserting projections 4| in apertures 42 to accurately locate the separators as the sections are assembled and welded.
The position of the separators is predetermined by punched apertures 42 and projections 4| so the may be readily assembled into the proper position for the desired size of drawer. The ends of arms 33 of two frame sections 3| are secured together in, a suitable manner, such as by welding; through the use of a. channel-shape welding strip 43 engaged in channel 34 and extending across the joint in the assembled frame sections. When strip 43 is welded in place a substantially rigid frame structure is obtained. Bottom corner brackets 4|! similar in form to the end portions 40 on each separator are mounted in the bottom corners of the front frame for supporting the bottom drawer supporting members in assembled relation. Brackets 40 have positioning projections thereon similar to the separators and are assembled and positioned by apertures 42 in the same manner as a separator. Top and bottom wall members In and la respectively are formed from a pair of duplicately formed pieces of sheet metal. Each member has a flat imperforaterectangular wall forming portion 44 provided with a laterally extending curved peripheral flange 45 forming curved corner sections about all four sides of the cabinet at both the top and the bottom. Peripheral flange 45 at the front of the cabinet is formed with a rearwardly extending lip 46 in spaced parallel relation to wall forming portion 44, as clearly shown in Figs. 2 and 5. In assembling the top and bottom wall members using these duplicate sheet metal structures, lips 46 engage over the inner edge of the arms at the top and bottom of front frame 30 with flanges 45 extending about curved flange .36 in the manner shown in Fig. 5, while peripheral flanges 45 at the sides and rear of the cabinet engage in overlapping relation with flanges l1 and 22 on back-side member l4 and front side members 2|, respectively.
A drawer suspension substantially similar to that shown in the aforementioned patent is used for supporting the drawers 4'! for movement into and out of the cabinet in a manner well known in the art. The case slide for the drawer sus pension mechanism used is of slightly different construction from that shown in the aforementioned patent and performs a new cooperation in the present cabinet not shown by the aforementioned patent. It is only necessary however to show the case slide for the drawer suspension mechanism to illustrate the improvements provided by the present invention. The case slide 48 is of channel-shaped construction having top and bottom tracks for cooperation in mounting the remainder of the drawer guidemechanism in a well-known manner. Case slide 48 is provided with offset attaching ears 49 in forwardly extending relation in an intermediate portion, as shown in Fig. 4. Ears 49 are spaced apart transversely of case slide 48 a distance equal to the spacing of apertures 20 and 29 in flanges I9 and 21 respectively, for projecting through these apertures to engage in interlocking engagement with flanges I9 and 21. The vertical dimension of ears 49 and apertures 26 and 29 respectively, provides for slidable engagement of the ears in the apertures into interlocked position with the flanges but prevents relative vertical movement of the flanges and ears.
In assembling the sections to form a complete file cabinet, front side members 2| have their front cornersections 23 engaged about the outer sides and front edges of vertical side members 32 of frame 30 with rearwardly extending flanges 24 extending rearwardly on the inside of side members 32 to embrace the front frame in the manner shown in Fig. 6. When side members 2| are assembled in this relation with frame 30 attaching channels 25 are then arranged to receive flanges l9 therein in interfitting relation. In this way, a back-side member and two front side members are assembled at opposite sides with frame 30. Pairs of case slides are then inserted into a position as shown in Fig. 4 for assembly in the cabinet. The rear central portions of case slides 48 are formed with outwardly offset and forwardly extending ears 49 arranged in spaced vertical relation for registry and interlocking engagement in apertures 20 and 29 respectively. Ears 49 on a plurality of case slides 48 are inserted through these registering apertures and then each case slide is moved forwardly so that the ears overlie the forward portions of flanges l9 and I! in advance of apertures 20 and 29 respectively. Ears 49 have a spaced position beyond the outer face of case slide 43 equal to the thickness of the metal of flanges l9 and 21 respectively for holding these flanges in tightly engaged non-shifting position in the interlocked relation, as shown in Figs. 5 and 6. When each case slide 48 has the tongues 49 engaged in this interlocked position, a pair of downwardly extending tongues 50 on each case slide will then be in position to extend through apertures 31 in front frame 3|] in horizontal alignment with are" apertures through which tongues 49 have been engaged, see Figs. 4 and 5. Interlocking emetic-are 'in downwardlyextending relation and'have a spaced vertical relation to each other equal to that of apertures--31. Ears 58B are offset outwardly beyond the outer face of case slide 48 at the front end thereof a distance equal to the thickness of the metal of channel 3 in side frame member 32 for firmly interlocking the case slide with' front 'frame 30 when the laterally extending portion ofears eileng'age channel member 40 forming the bottom margins of apertures 3'1. This position of ears '59 in assembled relation on front 'framesil is shown in dotted lines in Fig. 5. When case slides 48 are in this assembled position a locking tongue '5 l is in position to be bent laterallythrough aperture 33 between the pair of apertures 3'ithrough which tongues 58 extend; This provides for rigidly locking the case slide in the cabinet in the manner described in the aforementioned patent.
It will be noted'that the case slide in the present application has the ears as cooperating with the back-side member and front side members 2! to form an interlocking connection with these cabinet forming sections for rigidly retaining them in assembled cabinetforming relation in a manner not shown or suggested in the aforementioned patent. Then, by the interengagement of tongues ill) through the apertures or front frame 35 and the securing thereof ininterlocked position by bending tongue 5!.into aperture 38 the entire structure of the cabinet at the back and sides with front frame 38 is permanently assembled together in cabinet forming relation. It will thus be appreciated thatthis assembly can be made in a minimum' amount of time through this cooperation'of the back-side member, front frame 30, front side members 2! and the desired number of case slides t8 arranged in pairs at each side of the cabinet for supporting each drawer for movement into and out of the drawer opening in the front'of the cabinet defined by separators 333 as shown in the drawings.
Top and bottom walls l8 and it may then be applied by engaging a pair of the "duplicate members forming these walls with the upper and lower parts of the cabinet assembled as above described with lips is engaged on the inside of arms 33 at the upper and lower portions of front frame 39 as shown in Fig. 5. Then, peripheral curved flange 45 will engage on the outer sides of flanges fl and 22 at the top and bottom of the sides and back of the cabinet with the free edges terminating'adjacent the offset portions of the walls where the flanges fl and 22 are attached to provide a smooth wall surface on the outside of the cabinet at the sides and back merging into the curved corners on all sides of the cabinet. The top and bottom wall members may be suitably spot welded or welded by other suitable means to the side and back walls of the cabinet for completing the cabinet structure to produce a rigid assembled cabinet unit.
By constructing the cabinet in this manner, considerable space is saved so that the height of the cabinet for holding 'iive drawers of correspondence size files can be reduced so that it will only occupy the space heretofore used for four drawers of such correspondence. This saving in space is obtained partly in the cabinet construe-- tion by reason of the structural features herein described providing for the elimination of structural frame members within the cabinet shelves that have been heretofore required to provide suihcient strength to make the cabinet structures practical. Inthe present invention the formation of the wall members themselves gives the desired strength in the assembled cabinet structure in cooperation with front frame 3ll,.places the seams between the metal sections of the cabinet at the sides and thereby provides for the construction of the cabinet with rounded corners to meet the requirements of modern styling Without sacrificing strength and rigidity in the completed cabinet structure.
