Application April 9, 1936, Serial No. 73,417 12 Claims. (01. 129-29) This invention relates to improvements in fol-' The inventionfurther comprehends the provi-' sion of a card tray with guides on the side walls,

slidably mounting a follower supporting structure which carries a movable compressor plate and a lever operated mechanism for locking the follower structure against movement in the guide,

the lever of said mechanism being also constructed to operate the compressor plate.

A tray construction is provided by the invention for conveniently housin'gthe cards and supporting the follower structure provided 'witlr means to cooperate with the movable follower construction so that it may be operated efliciently in the tray and also with the provision of vmeans to make the trayv particularly useful for the fil ingof accounting machine cards. For-this purpose the tray is provided with special handle constructions so that it may be transported from place to place in a convenient manner.

Fig. 6 shows the parts forming the follower 50 supporting structure, compressor plate and lever operating mechanism disassembled and inperspectiv'e.

The tray has a front wall I formed of sheet metal provided with a rearwardly directed flange 55 -2 on the bottom edge and an inwardly and down wardlyexten'ding flange portion 3 on the upper edge. The sides of front wall I are bent rear-- wardly to provide attaching

flanges

4 and 5 for securing the front wall to the side members 6 of the tray.

Two side members are. provided, and are formed of sheet metal to provide side wall portions 1 formed'at the upper edges with outwardly directed flanges 8 terminating in verticallyextending sections 9 offset outwardly from Sidei pOItiODS' l in spaced parallel relation. The sections 9 are formed with lateral flanges forming the upper side edges .II'I of the tray having depending flange portions II at the inner edges.

Flanges 8, vertically projecting portions 9, upper edge portions I0 and flanges II form guide channels for slidably and adjustably supporting the follower construction in the tray in a manner that will be hereinafter described.

The lower edges of side wall portions I are formed with'inwardly extending bottom sections I2fthat have the inner. edge portions provided with return bends. The inner edge portions of the bottom sections I2 are arranged in spaced parallelrelation at opposite sides of the center of the tray to leave a central bottom opening in the tray indicated at I3 to provide a convenient means for projecting the cards upwardly out of the tray by means of any suitable instrument or by manual engagement with the bottoms of the cards.v A rear wall, not shown, is provided in the tray that is similar in construction to the front wall I.

A channel shaped member I4 formed of sheet metal is mounted against the inner face of front wall I near the top and extends transversely between'the sides I. An inner front plate I5 is mounted in spaced parallelrelation to front wall I along the inner edge of channel member I4 as label holder I1 is mounted in'the central por-' tion between the sides on flange I6 as shown in Figs. 1 and 5. At opposite ends of the label holderflange I6 and channel member I4 are formed with vertically aligned openings to receive handle I8 of U-shaped construction having vertically extending legs I 9 slidably engaged in said openings.

The lower ends of legs I 9 of the handle are provided with heads after they are inserted through the openings in flange l6 and channel member l4 that will thereafter prevent their removal from the channel member and will act in cooperation with the channel member when the handle is 'drawn upwardly through the openings to provide a convenient carrying handle for the tray.

Ratchet bars 20 are securely mounted in the upper outer corners of the channels formed in the side walls of the tray with the outer side faces engaged with the inner surfaces of vertically extending sections 9 and the upper edges engaged with the under faces of upper edge forming portions in. The lower edges of these ratchet bars 20 are formed with ratchet teeth indicated at 2|. These bars extend throughout the length of the side walls of the tray and serve in cooperation with mechanism carried by the follower, to be described, for retaining the follower in adjusted position.

The follower has a pair of arm members 22 of angular formation. These arm members have guide sections 23 thereof arranged in spaced parallel relation and slidably engaged in the channels formed in the side walls of the tray. ,Projections 24 on the upper edges of guide sections 23 slidably engage respectively between ratchet bars 26 and flanges II of the tray, as shown in Figs.

' "2 and 3, while the lower edges of guide sections upper edge in the formation of the return bend portion 21. I

The lower edge of the return bend portion 21 is formediwith laterally and rearwardly directed flanges 28 at opposite sides of supporting plate 26 leaving a central opening between the inner edges of the flanges'as clearly shown in Fig. 6. Below these flanges the supporting plate is formed with a pair of guide projections 29 while the lower edge of supporting plate'26 is recessed as indicated'at 30. Openings 3| are formed at opposite sides of the central portion of return bent flange 21 and threaded openings are formed in aligned relation with the openings 3 l' in support- 'plate 26 and flange 21.

ing plate 26.

Supporting arms 25 are formed with openings 32 that align with openings 3| in the assembled relation of the arm members 22 with supporting Assembly screws 33 are engaged through openings 3| and threaded into the supporting plate 26 to rigidly assemble arm members 22 and supporting plate-26 together.

These assembly screws have the heads thereof spacedrearwardly from the return bent flange 21 and are provided with cylindrical guide portions 34 for guiding follower locking bar 35 provided with vertical slots 36 to receive guide portions 34. The opposite ends of locking bar 315 are formed with lateral extensions 31 provided with ratchet teeth 38. .When the bar 35 is assembled on screws 33 as illustrated the lateral extensions 31 extend into the channels formed in the side walls of the tray below ratchet bars 20 so that ratchet teeth 38 thereon will cooperate with ratchet teeth 2! on bars 29 when looking bar 35 is moved upwardly to engage the teeth with one another.

The central portion of locking bar 35 is provided with an extension 39 formed with opening 40 to receive pivot bolt 4| for pivotally mounting looking lever 42 thereon. The extension 39 on looking bar 35 is guided by guide projections 29 on supporting plate 26 and the lower end portion of extension 39 is offset forwardly from the plane of locking bar 35 so that it will slidably engage the rear face of supporting plate 26 as clearly shown in the drawings. 1

Locking lever 42 is provided with an upwardly and rearwardly offset extension providing a handle 43 by which the lever is operated in a manner that will be presently described,

At the lower side edges-of supporting plate 26 are formed rearwardly extending ears 44. A compressor plate 45 is arranged in the tray in front of supporting plate 26and has a rearwardly extending flange 46 on the lower edge extending to the rear of supporting plate 26 below the lower edge thereof as clearly shown in Fig. 5, for example. Studs 46' are provided on flange 46 at opposite sides adjacent plate 45. Side flanges 41 are also provided on the sides of plate 45 that extend rearwardly and are joined at the lower ends with flange 46. These flanges 41 are arranged to extend adjacent the outer sides of ears 44 on supporting plate 26 as clearly shown in Figs. 2 and 3. Pivot pins 48 are inserted through aligned openings in the rear ends of ears 44 and flanges 41, for pivotally mounting compressor plate 45 on the supporting plate 26 in a vertical plane that is spaced rearwardly from the position of locking lever 42 as shown in Figs. 4 and 5.

Flange 46 of compressor plate 45 is formed with a pair of upwardly extending ears 49 adjacent opposite ends, and the lower ends of springs 50 are secured thereto having the'upper ends extending through slots 5| formed in the return bend por tion 21 and flanges 28 of the supporting plate structure and secured to locking bar 35 by inserting the ends of the springs through openings 52 in said bar. These springs normally operate to draw bar 35 downwardly and to move follower plate 45 upwardly about its pivot so that the follower plate will be moved toward the front face of supporting plate 26 into the position shown in Fig. 4.

Lever 42 has an arm 53 projecting from the opposite side of pivot pin 4| from operating handle 43. This arm 53 carries a roller 54 having its periphery projecting below the end of the arm for rolling engagement with the upper surface of flange 46 of compressor plate 45. Recess 30 in supporting plate 26 provides space for the free swinging movement of this arm 53 and its roller in operation. This operating lever 42 has handle 43 projecting between the inner edges of flanges 28 so that the upper end is above flanges 28 and the inner edges of the flanges serve to limit movement of the lever in opposite directions.

It was just pointed out that springs 50 normally operate to move compressor plate 45 toward supporting plate 26 and also to draw or slide locking bar 35 downwardly. This serves to disengage ratchet teeth 38 on extensions 31 from the ratchet teeth on ratchet bars 20 and hold the parts in a position so that the follower maybe slidably moved back and forth in the tray sup-ported and guided by arm members 22, guide sections 23 efficiently guiding the movement offlthe follower structure in its adjustment in the tray. v

The parts assume the position described above with operating lever 42 in the position illustrated in Fig. 2. Handle 43 in the released position of operating lever 42 engages against the end of flange 28 to the right side of the tray as shown in Fig. 2.

Fig. 3 illustrates operating lever 42 with its parts in the operative position with the handle extending toward the left of the tray and engaged with the end of flange 28 to the left-hand side of the tray as viewed in Fig. 3. In this position it will be noted that roller 54 has engaged the upper surface of flange 46 on compressor plate 45 and through the action of arm 53 it has moved the compressor plate structure, about its pivot mounting on supporting plate 26 so that flange 46 has been moved downwardly to engage studs 46 with the bottom |2 of the tray and plate 45 moved forwardly in the tray as shown in Fig. 5, away from supporting plate 26 for the purpose of compressing the cardsin the tray. In this position, arm 53 of lever 42 has moved across a vertical plane through the axis of pivot pin 4| or past what may be termed a-dead center position so that the tendency of spring 53 to raise compressor plate 45 about its pivot mounting serves to hold the operating lever in the position shown in Fig. 8 in operative positionv to compress the cards in the tray. With this operation of the compressor plate to compress the cards, the operation of the lever also serves through pivot pin 4| and extension 39 to slide lock bar 35 upwardly for engaging ratchet teeth 38 with ratchet teeth 2|. In so doing the lock bar 35 looks the follower construction against adjustment in the channels of the tray, thereby rendering the operation of the compressor plate effective to compress the cards- As soon as handle 43 of operating lever 42 is moved to the position of Fig. 2, springs 50 will follow this operation by moving compressor plate 45 about its pivot to the position shown in Fig. 4 while clamping bar 35 will be moved downwardly on screws 33 to the position shown in Fig. 4 for disengaging ratchet teeth 38 from ratchet teeth 2|.

It will be appreciated from the foregoing description that screws 33 provide assembling and guiding means for mounting the supporting arms on the supporting plate and the locking bar and operating lever in their operative positions thereon. It is, therefore, only necessary to mount the operating lever on the extension 39 and to assemble the compressor-plate structure on pivot 43, connecting the springs 50 to their proper anchorage whereupon the complete construction I is assembled It will also .be apparent that am members 22 may be easily assembled in the tray and the other parts connected thereto for quickly and conveniently mounting the follower structure for operation in the tray, thereby providing a tray and follower structure which is economical to manufacture and assemble, and also eflicient ator with a suitable handlethat may beprovided on the rear end of the tray;for transporting the tray of cards from place to place in a convenient manner. The handle assumes the position shown in Fig. 5 when not in use so that the tray may be conveniently stored in a suitable cabinet.
