' This invention relates to type cases together with means for loading them at the top so that the type may descend by gravity into the case. More particularly, the invention is concerned with a case having chan-. nels withprojecting ribs adapted to confine short type, grooved on its opposite sides, such as is used on a multigraph. I I, The primary object of the invention is to enable the rapid and certain loading of the type case from a temporary holder carrying a row of type. Theinvention is hereinafter more fully explained in connection with the drawings and its essential characteristics are 5 summarized in the; claims.

In the drawings, Fig. 1 is afront elevation of a portion of an upright type case I and a loading tube in position for discharging into the case; Fig. 2'isla verticaltrans- 0 verse section thereof, as indicated by the. line 22 on Fig. 1; Fig. 3. is a cross section through the loading tube and upper portion of the'case, as indicatedby the line 3-3 on Fig. 2; Fig. 4: is a cross sectionof thegloading tube; Fig. 5 is a fragmentary longitudinal section ofthe loading tube, as indicated by the line 5'5 .on Fig. 4:; Fig. 6 isa perg 1 spective of a portion of 'ingtype therein. 1 X 1 I As shown in Figs. 1, 2 and 3, the body of the type case comprises. a'series of parallel bars or rails 10 spaced apart and held equidistant by suitable means, as for instance by cross plates, of which the upper plate is shown at 14. Each of the rails 10 has ribs 11 at its opposite edgesjadjacent the front, thus providing under-cut channels in which short grooved type A may be loaded and descend by gravity, the ribs of the bars occupying grooves a in the sides of the-type. The rails are preferably I-shaped in cross section, the base portions 12 of the rails seating in grooves 15 in the cross bars. I j r' The type to be loaded are contained in a the loading tube, havtemporary holder comprising a tube 30 havinadvertently passing out of the tube 30.suitgroove aof the type; To prevent thertype abledetents 32, adjacent theopposite ends of the tube are provided. These detents are preferably integral tongues cut from the pork tion of the tube opposite the slot 31 andbent into the tube as shown in Figs. 4: and 5. The tongues projectin such direction and have such resilience that the ty e, may be readily slid into place in the tube beyond the tongue along the incline'ofthe tongue, but thereafter are retained by abutting the end of the tongue,- which automatically springs back into place.

To discharge described into the case, it is necessaryto cause the tube slot to align with aslot between ribs of the type case and to press back the detent tofreethe type in the tube. My type case provides for automatically effecting this release ,of the type when the tube is brought into registration with the case, as will now be described. 1 Y

The upper cross plate 14 of the type. case projects a material'distance above the upper ends ofthe rails 10, and mounted onthis cross plate behind the upper portions of the rails is a comb spring 20 having teeth 21 (one for each type channel) projecting upwardly directly behind prolongations of the type channels. Each spring tongue 21 isrounded forwardly at its upper end as, at 22 in Fig. 2. A cross bar 14 isrecessed slightly behind the spring tongues. 21, to provide space for'insertion of the rear, wall of the tube 30 behind any tongue. 4

In discharging the type from the tube into the desired channel, the tube is simply thus presses back the detent to release the type. Accordingly, the action of putting the tube in 'place automatically releases the row of type in the tube, so that they may slide by gravity down the tube and into the type channel corresponding to the tongue. The tongue thus serves the doublepurpose of typefrom the tubular holder I less than the height of the grooves a in the type, so that these type lie quite loosely on the ribs provided by the tube edges. Indischarging the type, it is desirable that their heads lie against the outer face of the tube so that all their groves will accurately align, and I effect this by arranging the case so that the tube will be tipped backwardly during the insertion, this backward tipping being sufiicient to maintain all the type with their heads seated against the outer face of the tube edge. To effect this, I incline rearwardly the forward upper face of the cross bars 14 as shown at '15 in Fig.. 2, and I cut off the upper ends of the rails 10' at right angles to such inclined face, and I bend back the tongues 21 of the spring comb. so that they are normally substantially parallel with the inclined face 15 of the cross bar.

To enable the tube 30 to be quickly put in place, embracing the spring tongue 21', I preferably taper the sides ofthese tongues as shown in Fig. 1. I bevel backwardly the upper portions of the. ribs 11 and also of the base portion 12 of the rails, as indicated at 17 in Fig. 1 and 18 in Fig. 2 respectively. This causes the upper portion of the'type case rails to properly register with the tube, the forward face of the ribs 10 thus aligning with the edges ofthe tube at the opposite sides of the slot 31 andthe forward face of the rear portions 14;, clearing the feet of the type. Finally, I taper the top portion of the type case rails, at least as to the front portion thereof, indicated at 19 in Fig. 1.

It will be seen that, when the loaded type tube is shoved downwardly into place em? bracing the tongue 21, a continuous'straight channel is provided for the type from the tube slot to, the corresponding type. case, slot, and the type are free to drop by gravity. The tapering of the sides of the spring tongues provides, for easy placement'of the tube, and the tapering of the upper ends of the rail 'ribs removes any possibility of the type catching on the upper ends of the ribs. Experience has demonstrated that with such a. type case as described,,the tubular carrier may be quickly put in place and will rapidly and efiectively discharge its type into the case.
