13F9 sw ngin referred to. It is to be understood, however, that the invention is not limited to any particular form or arrangement of the magazine column or to main or "split magazines or to the actual number thereof in the column, nor is it limited to any specific form of magazine removal means such as slides running in the magazine frames as in the aforesaid; patent or the magazines frames themselves arranged to serve as removal slides. Thus, the invention contemplates a variety of embodiments equivalent to that herein shown and such will be included within the scope of theappended claims.

- description of the various parts than is deemed necessary for a clear understanding of the pres- In the present instance, a column of three su-,

perposed matrix magazinesA, is shiftably supported in a. machine'of well known construction on upper and lower tracks B and C respectively formed on opposed side plates D which are seent invention. Briefly, each magazine supporting frame G is provided with a fore and aft slidable frame or carriage generally designated K,

cured to the usual face plate E and distributor,

bracket F comprising rigid members of the machine frame. The magazines A are of the well known split variety and cooperate each with a complementary upper conductor portion A, the magazines and their corresponding conductors being removably supported on separate base frames G which are rigidly secured together in superposed spaced relation by upper and lower tie plates H whereby .to form the unitary shiftable column of magazines. As usual, when a magazine is disposed in operating position on the machine it is'cooperatively aligned at its lower end with the assembler front I which is adapted to receive matrices released from such magazine in response to manipulation of the keyboard J in order to compose a line. At its upper end the active magazine cooperates with the usual distributing devices (not shown) of the machine, the latter devices serving to direct the matrices into the corresponding active conductor A which leads them back to the magazine A from w'nich they were drawn.

well understood, each magazine contains a different font of matrices (matrices differing as to style or the size of type face) and it is fre-' quently necessary to exchange a magazine in order to supply the type faces required for different pieces of composition. To facilitate the removal of a magazine and its replacement by another one containing a desired matrix font the machine may be provided with suitable magazine removing means preferably in the form, of a slidable conveyor capable of supporting the rather considerable weight of the magazine while withdrawing'itfrom the column in its own plane and thus easing the burden of the attendant. Such removal means may comprise, for example, a skeleton framework normally confined, within the limits of the; dimensions of the magazine frame proper and slidable relative thereto to a forwardly extended position, all as disclosed in the patenthereinbefore referred to, or it may be constituted by the magazine frames themselves arranged for fore and aft sliding relative to the column.

Whatever the forn'r'of the conveyor forguiding andsupporting a magazine while moving it fore and aft and during an exchanging operation, the present invention contemplates a construction whereby the conveyor, or the magazine sustaining portion thereof, may partake not only of the required fore and aft movement but also a movement designed to present the magazine, after Withdrawal from thecolumn inits own plane and without necessitating changing .of the grilllor handlingof the magazine proper, at a steeper in-' said carriage. comprising fore and aft longitudinal side rods or bars (one near each side of the respective supporting frame) rigidly joined together at their outer or front ends by a crosstie (not shown) whereby to form three sided skeleton frames capable of withdrawal or gravitating movement forwardly relative to the magazine frames. The side bars are let into longitudinal recesses formed in the main magazine frames in such manner as normally to accom- -modate the carriages both fiatwise and laterally within the limits of the dimensions of said frames.

The side bars are formed at their inner ends withsuitable upstanding portions L which provide shoulders adapted to engage the rear edge of narrow-keeper platesM and thus limit the forward extension of the carriages, the plates M being rigidly secured to the magazine frames (one plate at each side) and overlying the respective sidebars whereby to retain them within the aforesaid recesses and thus to sustain the carriages in the plane of their withdrawal. For sustaining the magazines against sliding forwardly both while in the column and when conveyed therefrom on the removal slides, and to permit return movement" of the slides merely by pushing rearwardly against the lower end of a magazine placed onan extended slide, the side bars of the slides are provided'with upstanding pins k and in spaced apart so as to accommodate between them with only a slight clearance the usual magazine stiffening cross-bars X.

The foregoing construction follows in all es sential respects thatdisclosed in the patent to which reference herein has repeatedly beenmade and the improvements provided by the present invention and in one form applicable to magazine removal carriages or slides of this general type will now be described.

As clearly indicated in the drawings and with reference to only one of the removal slides K (it being understood that the invention may be embodied in one or more of the slides) it is herein proposed to construct the side bars of the slide in two sections hingedly joined together at a point located somewhat beyond the forward end of themagazine frame after the slide is extended or withdrawn to the limit fixed by engagementof shoulders L against plates M. Thus, each side bar comprises an upper section N and a lower section 0 each of which is suitably halved out vertically so as to form an overlapping joint, see Fig. 4, adapted to hinge on a shoulder screw P. The screws P for the respective bars are preferably threaded into the inner overlapping portions of the lower sections 0 and countersunk in the outer overlapping portions of the upper sections N. Both ends of the screws thus lie flush with or below the vertical side surfaces of the bars so as not to interfere with sliding of the bars in the bar confining recesses in the magazine frames, said recesses being wide enough only to accommodate the over-all width of the bars with a slight clearance for free sliding movement.

Figs. 3 and 4 illustrate the details of construction of the hinged joint just referred to. Thus, each lower bar section is halved out vertically toward its upper end to provide a shoulder O" and beyond that an extension Q. The bottom edge Q of said extension is formed angular to the top edge whereby to engage a complementary angular surface N forming the base of the adjacent halved out portion of the upper section N, such engagement occurring when the two bar sections are straightened out with their top edges in a common plane as shown in Fig. 3. And in this relative position of the two bar sections the lower end of portions R of the upper sections bank squarely against the shoulders O on the lower sections over but only such vertical height (above the axis of the joint) as will permit sections 0 to swing downward on the pivot screws P. The oppositely disposed relatively angular surfaces S and T on the other half width portions of the respective bar sections N and 0 (surfaces formed in planes passing through the axis of the joint) serve, when engaged as indicated in Fig. l, to limit the extent of downward swing of the magazine conveying portion of the slidethat portion which, as already pointed out is constituted by the two lower bar sections 0 secured together at their forward ends as by a suitable cross-tie.

It will be evident that the lower portion of the hinged removal slide just described cannot be lowered out of the plane of its withdrawal until the tapered extensions Q of the lower side bars have passed out from under the keeper plates M. The attendant may then lower the withdrawn magazine and slide as a unit to the more steeply inclined position indicated in Fig. 1. From this position where the magazine and the slide are stably sustained the magazine may readily be grasped separately and lifted away. In Fig. 2, a slide K is indicated after partial extension forwardly out of a magazine frame G, the extensions Q of the lower side bar sections O still mainr taining the lower or magazine carrying portion of the slide in its plane of withdrawal.

After placing a new magazine on the lowered forward portion of the removal slide (making sure that the magazine stiffening bars X lie between the upper and lower sets of locating and retaining pins k and k) the slide may be swung upward about thehinge screws P into the plane of the upper portion of the slide whereupon the entire slide together with the magazine may be pushed rearwardly into the column. A downwardly cut bevel U at the extremity of each extension Q serves to facilitate entry of the side bars 0 beneath the keeper plates M when the lower section of the slide is elevated and pushed rearwardly into the column. It will be understood that as required and as explained in the aforementioned patent, suitable means such as insert plates V are provided for engaging notches W in the underside of the side bars 0 to hold the slides K in magazine operating position within the column and that the slides are suitably arranged for disengagement (by a slight lifting at their front ends) relative to such plates in order to effect their release for gravitating movement or extension forwardly when desired.

I claim as my invention:

1. In a typographical machine having a normally inclined frame supported therein for limited fore and aft sliding movement in its own plane and adapted to convey a magazine disposed flatwise thereon between an operating position within the machine and a removal position clear of the machine, said frame having means for locating and sustaining the magazine endwise in operating and removal positions and comprising upper and lower sections connected endwise by a non-dissociable hinged joint, said joint being so constructed as to permit the lower frame section and the magazine thereon when in removal position to be tilted up and down to an extent limited only by said joint.

2. In a typographical machine having a normally inclined frame supported therein for limited fore and aft sliding movement in its own plane and adapted to support and convey a magazine disposed flatwise thereon between an operating position Within the machine and a removal position clear of the machine, said frame comprising non-dissociable sections hingedly connected together and said connection being constructed to permit limited swinging of one section of the frame flatwise, while supported by the other section, out of the plane of sliding movement of the frame when the magazine thereon reaches removal position.

3. In a typographical machine having a fixed forwardly inclined frame provided with means for removably supporting a magazine fiatwise thereon in operating position in the machine, magazine removal means movable relative to said supporting frame first endwise in a plane parallel thereto to convey the magazine therefrom to a position clear of the frame and then angularly fiatwise to a magazine supporting position steeper than said plane, said removal means including a hinged joint self-operative to limit said angular movement and also means cooperative with the supporting frame for preventing such angular movement during endwise movement.

4. In a typographical machine having a fixed forwardly inclined magazine supporting frame adapted to removably support a magazine fiatwise thereon in operating position in the machine, magazine removal means arranged for limited fore and aft sliding movement in said supporting frame in the plane of inclination thereof and comprising non-dissociable upper and lower sections hingedly connected together endwise, said lower section being adapted to support and convey a magazine forwardly off its supporting frame to a removal position clear of said frame and to swing downwardly on said hinged connection upon reaching such position, and said connection being constructed to limit the extent of swinging movement of said lower section into and out of the plane of sliding movement and to sustain said lower section and the magazine thereon stably fiatwise and endwise for the magazine removal operation.
