9 Claims.

The invention relates to printers type cabinets. More especially it has reference to printers cabinets of sheet metal construction such as shown and described in U. S. Patent No. 2,106,163,

5 granted to me on January 25, 1938 in which gravity feed type chutes are supported on inclined shelves, and in which there is associated with each chute a keeper allowing removal of but one type block at a time.

In connection with type cabinets of the kind specifically referred to, I aim to minimize manufacturing costs through improved and simplified construction of various of its parts, particularly the type chutes and the associated keepers; and to enable, through provision of means for the purpose, adjustment of the chute supporting shelves so that any of them may be projected beyond others in the cabinet for greater convenience of the compositor in selecting type as needed, as well as for convenience in loading the type chutes from the front of the cabinet, and interchanging the chutes without necessitating complete removal of the shelves.

Other objects and attendant advantages will appear from the following detailed description of the attached drawings, wherein Fig. I is a fragmentary view in front elevation, of a printers type cabinet embodying the present improvements.

As shown in Figs. I, III and IV, my improved printers type cabinet is constructed from sheet metal with side walls whereof one is shown at I, intermediate the partition walls 2 and a rear wall 3, the cabinet being open at the front except at the lower part thereof which is provided with a number of utility drawers l. Each side wall I is finished off at the front with a columnar box bead 5 for the sake of greater stiffness, and to each of them is secured a pair of vertical battens 6 of hollow rectangular cross section. The partition walls 2 are formed hollow as shown in Fig. V, with the front bead strips I corresponding in width to the box beads 5 on the side walls. Attached in suitably-spaced relation and at corresponding levels to the battens 6 on the side walls I and to the partitions 2 are shelf guides 8 which incline downwardly toward the open front of the cabinet as best seen in Fig. III. Each of these shelf guides 8 is fashioned to channel configuration from sheet metal with top and bottom flanges 9 and Ill and a connecting web I I.

As best seen in Fig. IV, the top flange 9 terminates somewhat short of the bottom flange I0 0 at the lower end of each shelf guide 8 with the web II extendedupwardly as at I2 forwardly of said top flange. Also as shown, the end of the bottom flange Ill of the shelf guide is turned upwardly and rearwardly with resultant formation of a hook stop I3 for a purpose later on explained. Slidably engaged in corresponding guide channels 8 are shelves I4 of which one is illustrated in perspective in Fig. II, said shelves being formed with central openings I41: for the purpose of decreasing their weight. The side edges of each shelf are marginally offset upwardly as at l5, and to the bottoms of these margins are secured, by welding or otherwise, reinforcing strips I6 of like width. Transverse stiffening is had through downward and inward retroversion of the edge margins at the top and bottom ends of the shelf as at H, 58 the bottom edge being notched at the corners as at l9. As far as described, the construction of the shelf is identical with that of the shelves in my patent hereinbefore referred to; but in accordance with my present invention each shelf is provided at correspondingly allocated points at the side edges with additional notches 20 of a width equal substantially to that of the stops E3 on the guide channels 8. The purpose of this provision will be explained later on. Adjacent its upper and lower ends, each shelf I4 is provided (as in the patent supra) with transverse lines of apertures 2|, 22 adapted to be engaged respectively by upwardly projecting punched out tongueszt and pendant loops or eyes Z l (Figs. III and V) on the bottoms of sheet metal gravity feed chutes 25 of channel cross section, each of which is adapted to contain a series of type blocks T. Rods 24.2: extending continuously through the eyes 24 of the several chutes 25 on each shelf lock said chutes against displacement. Each chute 25 is closed at its upper end as instanced at 26 in Fig. V, and at its lower or delivery end, its side flanges 2'1 are reduced in height and there connected by a transverse stop lip 23 by which the column of type blocks T is arrested. From Figs. VI-VIII it will be observed that in accordance with my present invention, the bottom of the type chute 25 is indented adjacent its lower end, the indentation in this instance having the form of an angular depression 29 which slopes downward on a bias toward one bottom corner of the chute, and which terminates short of the stop lip 28 so that a narrow bottom portion 30 is left at said corner on the same level as the main portion of the chute bottom. Thus, as the type blocks T slide down the chute, the lowermost one of the series will be positioned at the normal level in the chute, while the next adjacent type block and a few others behind it will be tilted at an angle relative to said lowermost block as shown in Figs. VII and VIII. The lower end of the chute 25 is moreover provided with a notch 3! which extends downward centrally of the stop lip 23 and rearwardly of the chute bottom to a distance somewhat in excess of the width of one of the type blocks.

Associated with each type chute 2 5 is a keeper 32 comprising a component 33 which is fashioned from a single length of spring wire with a pair of forwardly projecting fingers 34, 35 of slightly differing lengths, and with a pair of rearwardlyextending parallel shanks 36; and side components 3? with bosses 38 along their top edges in which the shanks of the wire component are frictionally engaged. The side components 3l of the keeper are in the form of sheet metal stampings of sectoral configuration with pressed out stiffening ribs 39 and with curls along their top edges constituting the bosses 38 in which the shanks 36 of the wire component 33 are frictionally engaged. As shown in Figs. VII-IX, the side components 37 of the keeper are ap-ertured to engage outwardly projecting pivot lugs 40 welded to or otherwise permanently attached to the sides of the chute 25. By means of spring washers 4| incorporated in the pivotal connections just described, the keeper 32 is held against accidental displacement in positions of vertical adjustment relative to its chute 25. With the keeper properly positioned as in Fig. VII, the longer finger 34 slightly overlaps the rear corner of the lowermost type block in the chute while the shorter finger 35 rests on the next adjacent block slightly rearwardly of the top corner of the latter. Accordingly, the endmost type block can be readily removed by first grasping it between the fingers as shown in Fig. VII, and then turning it forwardly about the edge of the stop lip, the latter operation being facilitated by reason of the possibility of finger access to the bottom of the block through the notch 3| in the lower end of the chute. Upon removal of a type block in the manner explained, the other blocks in the series will slide downward until the then lowermost one occupies the position vacated by the one just removed. The keeper 32 thus allows removal of but a single type block from the chute at a time. The formation of the keepers from wire results in an open construction through which the type blocks at the delivery ends of the chutes can be seen at all times. This is of great practical advantage in that it dispenses with, the need for warning slugs as heretofore, and moreover in that it makes possible the loading ofthe chutes without the necessity for lifting the keepers and disturbing their adjustment as was the case with the construction shown in my Patent #2,106,163.

In Figs. VI and VII, one of the shanks of the keeper is laterally offset as at 42 with attendant provision of a fiat rounded projection over which is slipped a removable marker cap or button 43 bearing the letter corresponding to that of the type blocks in the chute. As an alternative, a. projection for a similar purpose may be formed at the crotch between the fingers 34, 35 of the keeper 32 as at 420. in Fig. IX. The last described feature is new to my present invention, and is of great convenience to the printer or compositor in that it facilitates identification of the various chutes for quick selection of the type.

When the shelves I4 are in their normal positions in the cabinet, the frontal edges of their corner notches l9 are engaged and locked within the hook stops [3 on the bottom flanges ll] of the channel guides 8. Through provision of the additional notches 20 in the side edges of the shelves l4, it is possible to project any desired shelf outward beyond as shown in connection with the shelf second from the top of Fig. III, the others for convenience of type selection, for convenience of filling the chutes on such shelf from the front with a loader such as shown and described in my patent supra. The procedure in extending the shelves is as follows: The selected shelf is first pushed inward until the transverse edges of its corner notches H) are out of the stop hooks I3 on the guides 8, then lifted slightly at its lower or front ends until the notches clear the hooks, then moved outward until the side notches 20 register with the hook stops, then lowered onto the bottom flanges of the guides and finally moved further outward to engage and lock the transverse upper edges of the side notches in said stop hooks. With the shelf so projected it is obviously easier for the printer or compositor to select type from the chutes thereon, or to fill the chutes from the front of the cabinet as already pointed out hereinbefore. It will moreover be noted from Fig. III, that when a shelf is partly projected and so held by coaction of the notches 20 and the stop hooks 53, the locking rod 241: is beyond the front of the cabinet so that it can be withdrawn for convenience of interchanging type chuteswithout necessitating-complete removalof the shelf as was heretofore neczfr's igin essary. This is of great advantage in crowded composing rooms with restricted space for maneuvering. Complete removal of a shelf may be effected when required simply by sliding it outward of the channel guides after release of the corner notches from the stop hooks as illustrated at the top of Fig. III.

Figs. X and XI show a modified form of type chute, in which endmost type displacing means is in the form of an upward spot indentation 29a." of small area, at the juncture between the lip 28a and the chute bottom at one side of the finger clearance notch 3m.

Figs. XII and XIII show another modification in which the clearance notch 31b is disposed to one side of the center of the chute and the type lifting indentation 29b is located at the opposite side of said notch.

In the modification of Figs. XIV, XV and XVI, the type lifting indentation 290 is in the form of a V indentation into the lower corner of the chute adjacent one side thereof.

In Figs. XVII, XVIII and IUX, type lifting indentation 29d is in the form of a corner depression with cut sides.

In the modification of Figs. XX-XIGI, the type lifting element 29e is in the form of a tongue or tab cut out of the stop lip 28c and depressed through the position shown in Fig. XXIII to the position shown in Fig. XXI so that its top surface becomes flush with the top surface of the chute 25c.

Since in each one of the modifications the construction is the same except for the formation of the type lifting means, the same reference numerals have been employed to designate the corresponding parts with addition, however, in each instance of different letters for convenience of distinction.
