13 Claims.

This invention relates to improvements in the construction of cabinets for visible card indexes.

The invention provides an improved tray and follower construction arranged so that a tail piece is freely movable in operation relative to the tray so as to retain the tray against complete detachment from the cabinet, provide a tail piece that occupies less space in comparison with previous devices, provide a tail piece that is manually operable in a convenient manner for quick detachment of the tray and tail piece from connection with the cabinet, and also provide for ready re-insertion of the tail piece and tray into the cabinet after it has been detached.

The invention further comprehends the provision of a rear end construction for the card index tray that will facilitate the `mounting of the tail piece thereon for eicient operation and at the same time distribute the load on the tray over a substantial area to prevent breakage or damage of parts, at the same time providing a compact structure tha-t reduces loss of filing space in the cabinet to a minimum.

A cabinet indicated at l has an outer casing formed of side Walls 2, top wall 3, rear wall 4, bottom wall 5, and iront wall 6. This casing has the several walls formed of sheet metal constructed and assembled in the manner disclosed in applicants copending application Serial No. 126,015, iiled February 1G, 1937.

Side frames are mounted on the inside of each side wall 2 of the cabinet and comprises a iront vertical member l, a rear vertical member 8 and a vertical stop member 9. The Vertical members are connected together at the upper and lower ends by top member i and bottom channel II', see Fig. 1. Top and bottom cross members I2 extend between Vertical members "I and 8 of the side frames at opposite sides of the cabinet for securing them in position in the outer casing. Front and rear vertical members 'I and 8 are formed with two rows of struck-out tongues I3 and I4 respectively, arranged in spaced ver-tical relation. The tongues on the rear frame member are in horizontal alignment with the corresponding tongues on the front frame member and tongues Id are offset slightly from tongues I3.

riongues i3 slidably support slide members i5. Slide members I5 are formed with sheet metal having a partition forming section I6 at the bottom extending transversely between the side walls of the cabinet, with offset margins I'I at opposite sides terminating in upwardly extending side walls it formed with inwardly extending top flanges is at the upper edges. The rear end of partition section I6 is formed with an upwardly extending rear wall 2U, see Fig. 2, while the front portion is formed with a return bend to provide stop means 2i in the form of a hook.

Each slide member I5 is slidably supported by the side frames through having offset side margins I'I slide-bly supported by tongues I3 on the front and rear vertical frame members at each side of the cabinet. Tongues I 4 operate to retain each slide member in sliding engagement with tongues I3 and to prevent Vertical movement of the slide member in the cabinet. Each slide member provides a tray compartment in the casing open at the front end.

One side wall I8 of each slide member carries a spring latch 22 that engages with vertical stop member 9 as shown in Fig. 2 for releasably retaining slide member I in its housed, rearmost position in the cabinet. When a card index tray carried by the slide member is pulled out of the cabinet, slide member I 5 can be pulled forwardly to a limited extent as shown in Figs. 1 and 2 and in such operation, spring latch 22 is forcibly cammed over stop member 9 into engagement with inclined latching flange 23 carried at the rear edge of front vertical member 1, as illustrated in Figs. l and 2 showing spring latch 22 on one of the trays engaged therewith. It will be seen that spring latch 22 limits the forward movement of a slide member in the cabinet so that it can not be normally withdrawn beyond the position illustrated in Figs. l and 2. When it is desired to detach the slide member from the cabinet, a special tool in the form of a slender piece of spring steel can be inserted under latch 22 in order to move it past vertical front member 1.

The portions of the cabinet and slide member as described above are fully disclosed in applicants copending application aforementioned.

A card index tray 25 is provided for each slide member and slidably mounted therein. Each tray is formed of sheet metal having a bottom 26 turned upwardly at the side edges to form side walls 21, with inwardly extending top flange portion 28, terminating in inner depending flanges 29, arranged in spaced parallel relation to side walls 21 on the inside thereof. The lower end of ilanges 29 terminate in spaced relation to bottom 26 to provide guide channels for receiving visible index card holders, in a manner well known in the art. The rear end of each tray is provided with recesses 39 in bottom 26, opening rearwardly, while sidewalls 21, top section 28 and anges 29 are cut away at the rear end of the tray as shown in Fig. 8 to provide an inclined edge on side wall 21 indicated at 3| inclining downwardly toward the bottom 26 as the incline progresses rearwardly to the rear edge of the tray.

A rear end member 32 is formed to provide a base section 33 seated on the rear margin of bottom 25. Base section 33 is provided with offset portions 34 over recesses 35. The forward edge of base section 33 is formed with a cylindrical portion 35 at the ends and between oifset sections 34 as clearly shown in Fig. 8 to provide one portion of a hinge. The rear edge of base section 33 is provided with an upstanding rear wall extension 33 terminating in a forwardly directed top iiange 31. Base section 33 is seated on the rear margin of bottom 26 and spot welded or otherwise rigidly secured thereto so as to form the rear wall or end structure of the tray and provide a mounting for the follower construction hereinafter described.

Rear end bracket members 38 are formed in pairs, each bracket of a pair being formed opposite to the other, to provide a securing foot 39 spot welded or otherwise rigidly secured to the top face of base section 33 throughout each end thereof, a pair of brackets being mounted one along each side of a tray. The remaining Dortion of each rear end bracket 38 extends along the inner face of one of the side walls 21 in con- 75 tact therewith, and has an inclined upper edge corresponding to the inclined upper edge 3l of the side wall. The forward end of each rear end bracket 38 is formed with an offset extension 43 projecting along the inner face of flange 29 at the rear end thereof, to which it is suitably secured by spot welding or the like. These -brackets 38 provide a rigid rear end structure in cooperation with rear end member 32, that effectively distributes the load on the rear end of the tray.

A pair of links 4l are formed at opposite ends to provide tubular portions 42, the portions 42 at the forward end of each link being inserted into one oi the recesses 30 and engaged between the ends of tubular portions on base member 33 terminating adjacent offset sections 34, in which position a hinge pin 43 may be inserted through tubular portions 35 and 42 to hingedly secure the front ends of the pair of links 4I on rear end member 32. The opposite ends of links 4I extend to the rear of the tray through recesses 3U and offset section 34 where they hingedly4 mount tail piece 44.

Tail piece 44 is formed of a strip of sheet metal 45 provided with a folded upper edge 46 and a lateral flange 41 on the lower edge extended forwardly and formed at intervals with hinge knuckles 43 in spaced aligned relation. Pairs of hinge knuckles 48 are arranged to receive each cylindrical end 42 on the rear end ol each link 4I therebetween, so that when the cylindrical portion 42 is aligned with hinge knuckles 48, hinge pin 49 may be inserted through the aligned hinge portions to hingedly secure tail piece 44 to links 4I.

In line with links 4I, the lower edge of strip member 45 is formed with lateral projections 5D that extend forwardly, as clearly shown in Fig. 8. Projections 59 lie underneath and overlap links 4I, as clearly shown in Fig. '7, and are adapted to slide on the upper face of partition section I6 of slide member I5 so that the follower is slidably supported in a slide section for sliding movement back and forth in the slide member in a transversely extending position. The ends of strip section 45 are provided with lateral rearwardly extending flanges 52 adapted to slidably engage side walls I8 of slide member I5 to cooperate in slidably guiding the tail piece in the slide member.

Strip member 45 is arranged to extend transversely in each slide member with the ends terminating in close adjacent relation to side walls I8, while the top and bottom edges are arranged to extend between and terminate adjacent to partition section I6 and flanges I 9. Tail piece 44 is freely movable relative to tray 25 and therefore gravitates to its own position in slide member I5 by reason of the double hinge connection of links 4I with the tail piece and tray. This allows the lower faces of projections to slide along the upper face of the bottom of partition section I6 for cooperating in guiding the tail piece in its movement back and forth in slide member I5. The distance between the upper edge of strip section 45 of the tail piece and the forward ends of projections 50 is much greater than the distance between the under faces of anges I9 and the upper face of partition section I6. It will therefore be understood that any tendency of tail piece 44 to turn over in slide member I5 will be prevented through the cooperation of strip section 45 and tongues 50.

A leaf spring 53 arranged in folded form as illustrated in Fig. 9 has the lower end thereof provided with projections 54 engaging in openings 55 in projections 50. The fold portion of leaf springs 53 is positioned next to strip section i with the leaf springs positioned between projections 5i) and links 4I, the upper fold of each leaf spring 53 being engaged with links 4I. These folded leaf springs normally tend to separate projections 5D from links 4l so as to maintain the lower faces of projections 50 in sliding engagement with the upper face of partition section Iii of each slide member. In this way, when projections 50 reach the forward end of each slide member, they readily engage stop means or return bend hook portions 2l to arrest the forward movement of the tail piece and thereby prevent its detachment from the slide member. Springs 53 normally tend to rotate the tail piece relative to links 4l causing most of the lost motion between the tail piece and slide member to be taken up, and also secure uniform sliding and guiding action of the tail piece in' the slide member.

Tail piece 44 rides freely in the tray during rearward and forward movement of the tray into and out of its slide member I5, but as the tray is moved outwardly in front of slide member l5, projections 5U on the tail piece engage hook 2i of the slide member, in the manner illustrated in Fig. 3, so as to limit the forward movement of the tray relative to the slide member. operation will take place in the initial pulling of a tray outwardly from its slide member so that the tray will be pulled outwardly from its slide member into the position shown in Fig. 3 until projections 5i! engage hooks 21, whereupon with the slide memlber structure hereinabove described, further forward movement of the tray relative to the cabinet will pull the slide member outwardly to its forward limit of movement. During this operation the parts will retain the position shown in Fig. 3. The card index may then have its card indexes referred to in the usual and well known manner and the tray may 'be swung downwardly from the position shown in Fig. 3 about its hinge connection with links 4l into the position shown in Fig. 5.

Should it be desired to completely detach the card index tray from connection with its slide member and the cabinet, this may be done by pulling the tray outwardly to the position shown in Fig. 3. Then, the tray and its tail piece is pushed inwardly a slight distance to the position shown in Fig. 4 where the forward ends of projections 5B are disengaged from hook member 2 l. By manually moving the upper edge of strip portion i5 rearwardly in the slide member, to move it in a clockwise direction as shown in Fig. 4 about its hinged mounting on links 4I, the ends of projections 5i! will be elevated into the position shown in Fig. 4 while springs 53 will be compressed. This will elevate the forward ends of projections 5D suiciently high that they will clear stop means or hooks 2 I, whereupon the tray and its follower construction including the tail piece may be completely withdrawn from attachment to its slide member and the cabinet.

When it is desired to re-insert the tray and its tail piece in the slide member, the procedure illustrated generally in Fig. 'l is followed. The rear end of the tray with its tail piece are positioned in front of the open front end of a slide member' in the cabinet arranged in its outwardly projected position, as shown in Fig. 7. Then, by manually engaging one or both projections 50 on the lower side and pressing them upwardly As this l,

Cil

against the bottom of the tray as indicated in Fig. 7, spring 53will again-be compressed whereupon the tail piece with its parts held manually in the relation shown in Fig. 7 can be inserted into the slide member and freely and slidably reengaged with the slide member for sliding movement therein, in the manner above described.

ASlide member l5 will be retained in its outer limit of movement during inward sliding movement of a tray therein until the front structure of the tray engages the front end of the slide member. When this position is reached, further rearward or inward movement of a tray toward the cabinet will cause the slide member to move rearwardly therewith into the completely housed and innermost position.

, The drawings illustrate in Figs. 3 to 6, as well as Fig. 2, a bracket 56 mounted on bottom 26 of the tray in advance of rear end member 32 for hingedly supporting top cover 5l. The purpose of this bracket and the top cover are well known in the art.

A tray and follower construction with the tail piece constructed as above described will not only have free hinging movement on the tray relative to the tail piece and its slide member, but can also have lateral shifting movement from side to side to a limited extent due to the fact that one end of the tail piece can move inwardly into slide member l5 a slight distance when the front end of a tray is shifted laterally with respect to its slide mem-ber. A limited amount of clearance between the slide member and tray provides for this sluiting in conjunction with the structure described.
