"The: housing is open at the top, between points l2 and I3, to provide access to the cards therein; but it may be closed when not in use by an arcuate sheet metal hood I4 which is mounted for rotation about the axial center of the housing and provided with an outwardly extending flange or lip l4a which serves both to limit the movement of the hood, in both directions, and to afford a finger hold for operating the hood.

Welded or otherwise secured to the respective interior surfaces of the two side walls of housing II] are a pair of oppositely disposed bearing blocks I5 and I B which provide bearings for both the hood I4 and an index wheel or drum which is desi nated as a whole by reference numeral IT.

The index wheel includes a cross shaft 18,

journaled at its ends in the bearing blocks and I6, which are bored axially to afford bearings for the shaft and slotted radially, as indicated at H) and (Figs. 1, 2 and 3), to permit the index wheel to be lifted bodily from its bearings and from the housing.

A cylindrical hub 2| is fixedly secured to shaft l8 and is rotatable therewith. Said hub spans the space between the opposing faces of bearing blocks I5 and I6, and thus serves to locate index wheel [1 axially between the housing walls.

Attached to and extending radially from hub 2| are four spokes 22 of a hand wheel 23 having an annular tubular rim 24 which is welded to the outer ends of said spokes. Hand wheel 23 serves to facilitate manual rotation of the index wheel.

As depicted most clearly in Figs. 2 and 5, hub 2| has eight peripheral slots 25 equally spaced circumferentially and each'adapted to receive a wedge block 26 and the inner edge portion of a sheet metal radially extending spoke 21a forming one leg of a generally V-shaped sheet metal element 21 which includes a peripheral rim portion 211) and an inwardly directed radial flange 210. Each wedge block 26 is secured to hub 2| by means such as a pair of capscrews '28 which are threaded into the hub; and each serves firmly to clamp to the hub the immediately adjacent spoke 21a.

Each inwardly directed flange 210 is welded or otherwise secured to the spoke portion 21a of the next adjacent V-shaped element 21; and, as will be apparent, the several elements 21 constitute sectors forming, conjointly, a polygonal sheet metal wheel structure which completely encompasses the hub and, in the disclosed embodiment, has eight fiat peripheral surfaces constituting the sides of an octagon.

The hub 2| and shaft l8, together with the structure composed of the sheet metal elements 21, constitute what is herein referred to as a mounting drum, on the periphery of which are detachably mounted a number of card-holding trays 29 equal to the number of flat surfaces on the drum. Each tray 29 is composed of a sheet metal member 30 having a bottom plate 30a, two side walls 3% and 300, a high end wall 30d and a low end wall tile. As viewed in Fig. '7, the cross section of each tray has the form of a channel; and the upper edges of the side walls 30b and 300 are each curved in concentric relationship to the axis of the mounting drum. Welded or otherwise secured to the arcuate upper edge of each side wall 30b, 330 is a bar 3| of round cross section. Each of said bars extends from the high wall 39d to a point 32 somewhat beyond the front edge of the tray, as shown in Fig. 5. The overhanging end 32 of each bar 3] is slotted, as shown of the tail pieces.

in Fig. 6, to receive a flange 33 forming an integral part of the high end wall 30d of the next adjacent card tray. This serves to avoid the presence of a gap between the ends of the card-carrying bars of one tray and the high end wall of the next tray, through which gap cards might become unintentionally detached; and it also aids in lining up the trays on the drum.

Each bar 3| with its supporting side wall 302) or 360 forms a card track, the pair of which are spaced laterally in correspondence with the spacing of two keyhole shaped notches 34 in the lower edge of each card 35, an exemplary embodiment of which is shown in Fig. 4. The cards are attached to the tracks by notches 34, and each tray is capable of accommodating a large number of cards. Groups of cards may be threaded onto the tracks at the front end thereof, the end wall 36c being low enough to afford no obstruction, and they may be withdrawn from the same end of the track when the tray is lifted at the front end, as shown in dot and dash lines -in Fig. 5, or is removed from the drum. Individual cards or small numbers thereof may, however, be withdrawn or placed upon the tracks, without moving the trays, by force applied to the cards which distorts the lower portions of cards adjacent the slots. The rear end wall 30d is high enough to form a backstop for the cards, thus enabling the tray to be lifted at its front end and removed from the drum without any of the cards becoming detached.

Extending outwardly in a radial direction from each rim portion 21b, and integral therewith, are a pair of laterally spaced lugs 36, to each of which is rigidly secured a pin 31. Lugs 38 are spaced axially of the drum an amount sufficient to receive between them the rear end of a tray; and the two side walls 301) and 300 are each notched at 38 (see Fig. 5) to engage said pins 31. Pins 31 serve to anchor and locate the back ends of their repsective trays, while the front end of each tray is detachably secured to the drum by a pair of latch members 39, 40 which are pivotally mounted on a shaft 4 I, the two ends of which are journaled in a pair of lugs 42 which are integral with their respectively associated rim portions 21b and project inwardly in a radial direction therefrom. The two latch members 39 and 40 project through apertures 43 in the rim portion and through registering apertures 44 in the bottom plate Sim of the card tray. The hook ends of the latches overlie and bear down upon the bottom plate of the card tray, as shown in Fig. 5, and thus serve to hold down the front end of the tray. Each latch member 39, 40, or at least one of them, has an integral tail piece 39a, 400. which, preferably, is curved arcuately about the axis of shaft 4| and projects through aligned openings 45, 46 in rim portion 21b and bottom rotate together, thereby making it unnecessaryv to depress both tail pieces manually at one time to remove a tray. The operator thus has one hand free to lift the front end of the released card tray, while the other is used to depress one The two latch members of jacent spoke. 251a.
