10 Claims. (Cl. 199-11) This invention relates to typographical composing, casting and distributing machines of the conventional type, such as Linotype machines of the general organization represented in the basic Mergenthaler United States Letters Patent No. 436,532, wherein matrices are released from their storage magazine in the order in which their characters are to appear in print, then composed in line, the composed line transferred to the face of a slotted mold, the mold filled with molten metal to form a type bar or slug against the matrices, and the matrices thereafter returned through distributing mechanism to the magazine from which they started.

The speed of operation of the commercial machines is normally between six to seven cycles per minute or, to express it differently, six to seven lines per minute. In recent years, there has been a growing demand for machines capable of operating at a higher speed, especially in the case of machines equipped with tape-operated keyboards.

The present invention is intended to meet this demand without departing from the basic design of existing machines. The exact manner in which this is accomplished will best he understood from the detailed description to follow, but it may be stated at this point that, as a result of the various improvements incorporated throughout the machine, the speed has been practically doubled, that is to say, increased up to twelve cycles per minute or slightly higher. While all of the improvements have been made with this high speed operation in view, nevertheless many of them would be equally useful in machines operated at normal speeds.

Matrix magazines and shifting mechanism (Figs. 1 to 4 and 14) While the machine could be equipped with a single magazine, it is herein shown with two magazines A containing matrices X of two different fonts. These magazines are desirably of the so-called Model 5 variety, which means that they do not carry escapements. The magazines are removably mounted upon separate base frames A which conjointly constitute a shift frame which may be raised and lowered to bring either magazine into operative position. It may be noted at this point that the inclination of the magazines is seventy degrees (70) from the horizontal, this being a steep inclination as compared to the normal inclination of about thirty-seven degrees (37) in standard machines. By increasing the angle of inclination of the magazines, the travel of the matrices from and to the magazines will be greatly accelerated. While the travel of the matrices could be accelerated even more by arranging the magazines in a truly vertical position, such an arrangement has been found to lead to other complications and should be avoided. An angle of the order of seventy degrees (70) has been found to give the most satisfactory results and especially when the machine is run at a speed of twelve cycles per minute.

Due to the steep inclination of the magazines, the right angular path in which they are shifted has been correspondingly reduced, that is to say, to twenty degrees (20) from the horizontal, which angle is the complement of the seventy degree (70) angle of inclination. Advantage has been taken of this reduced angle of shift by slidably suspending the shift frame at its upper end. This has been accomplished by providing the shift frame at its opposite sides with a pair of supporting plates A (arranged at the twenty degree (20) angle) running on rollers A journaled in brackets A adjustably mounted in the fixed machine frame (Figs. 3 and 14). The supporting plates A are attached rigidly to the lower base frame and extend upwardly far enough to provide seats A for the customary pivot pins A protruding laterally from the upper base frame. Three adjustments are proposition (see in particular Fig. 14): First, the pivot pin seats A are adjustable by set screws A which locatethe upper base frame and the'magazine thereon in proper longitudinal position within the shift frame; second, the roller carrying brackets A are adjustable 'by set screws A which locate the shift frame as 'a whole in a longitudinal direction; and third, the shift frame as a whole is located in a transverse direction by set'screws A carried by the'brackets A and bearing against the side edges of the supportingplates A a At its lower end, the shift frame is unsupported except for the raising and lowering mechanism which will now be described. Rotatably mounted in the fixed machine frame are two parallelrock'shafts A one near the lower end of the shift frame and the other. near the upper end thereof. Each of these rock shafts '(see Figs. 3 and 4) has fastened thereto at its'opposite ends crank arms Matrix releasing devices (Figs. 9, 10, 13 and 'to 17) Each of the magazines A has associated therewith a bank of escaprnents B independently supported. in the, corresponding base frame A. These escapements, being of the Model 5 type, have actuating slides B whose; nose portions are arranged substantially flush with the discharge end of the magazine. Due to the steep inclination of the magazines, theactuating-s lides B of-the 7 magazine in operative position are arranged to be engaged directly by the upper ends of a corresponding series of reeds B whose lower ends are likewise arranged to be engaged directly'by the usual power-operated keyboard slides B As a feature of the present invention, the actuating reeds B instead of being'mounted in the fixed machine frame, are mounted in an auxiliary rectangular'supporting frame 13* which is detachably connected to the fixed machine frame so that the whole .series of reeds Inlay shift frame, Each of the rock shafts also has fastened thereto, at its opposite ends, "further crank arms A the corresponding pair on the respective rock shafts being pivotally connected by means of :long'fore-and-aft links A his now evident that the two crank shafts will be caused to rotate in unison in raising and lowering the shift frame and will maintain the 'magazines at the proper inclination in both positions of the shift frame. The rotation ofthe crank shafts is'effected by means of a hand lever A fastened directly to the lower shaft and located at the front of the machine. 7

In order to limit the movement of the shift frame in opposite directions and to locate the selected magazine accurately its operative position, two pairs of fixed stops, in .the form of adjustable set screws A are provided, one at each of the four-corners of the shift frame. Each pair of stops is located in a U-shaped bracket A attached to the fixed machine frame (Fig. '3) and arranged to be engaged by a lug A protruding from the lower base frame. As can be seen at once, when'the shift frame is in its lower position, all four lugs A thereon will bank against the lower fixed stops (as in Fig. 3), whereas when the shift frame 'is in its upper position, all four lugs will bank against the upper fixed stops. 1

' The shift frame is .held in either of :its two different positions by means of .a counterbalancing spring A which is connected to the shift frame through the medium of ashort crank shaft A mounted in the fixed machine frame (Figs. 3 and 4). This crankshaft has two arms I upon the lower .fixed stops A it being noted that at this time the crank arm A approaches the vertical and holds the counterbalancing spring near a dead center position. When, however, the shift frame is raised to its upper position, the crank arm A will be turned down to a nearly horizontal position and thus, because of the increased leverage, enable the counterbalancing spring g to exert a greater lifting force and one which is sufficient to overcome the weight of the whole magazine structure and hold it firmly against the upper fixed stops A The arms A 5 and the associated parts represent the usualattachments for removing'the magazines when desired. 7 They are, in general, similar to those shown and described in the McNamara Patent No. 1,586,316 and form no part of the present invention.

The parts are so I be removed as a unit. The auxiliary supporting .frame B is provided with upper and lower comb plates .3 to guide the reeds in their upward and downward movements and also near the top with a bankingbar 3B which supports the reeds in their downward position. Springs B attached to the lowercomb plate, act to return the reeds to their lower position after they have been raised by the keyboard slides B to operate the matrix releasing escapements.

The detachable mounting ofthe reed supporting frame 7 is best shown in Fig. 13. There it will be seen that the frame is supported at its lower end and at 'oppositesides by meansof slotted lugs B arranged to fit over supporting studs B projecting inwardly from brackets 3 attached to the fixed machine frame. The lugs E .are provided at the upper ends of their slots with adjustable set screws B which locate the frame. in a vertical direction; and the brackets B (see Fig. 16) are provided with-adjustable set screws B which locate the frame in a transverse direction. 'At its upper end and at. opposite sides, the reed frame is provided with a pair of thumb screws B mounted in adjustable thimbles B on ears. B pr.o-

jecting laterally from the reed frame ,(Fig. 15). At their rear ends, the thumb screws are threaded into, sockets formed in brackets B 5 projecting laterally from the fixed machine frame. As will be apparent from the drawing, by loosening the thumb screws B the reed frame can be quickly detached from the brackets B and then lifted upwardly from the supporting studs B y Inrestoring the frame, its slotted lugs B? are lowered into place upon the supporting studs 3 and the thumb screws B then tightened up to attachthe frame tothefixed brackets B1 The adjustable thimoles B serve to locate which, as usual, is arranged to be swung from and to its,

operative position in the fixedmachine frame. The frame B also contains (Fig. 9) thecustornary power mechanism for operating the slides B consisting of the pivoted cam yokes B the rotary cams B (which make one com plete rotation at each matrix releasing operation), the

continuously driven rolls B for'operating the camsB the triggers B controlling the operation of the cam yokes, and the trigger actuating slidesB These trigger actuating slides B may be operated manually from the keyboard B 3 or automatically by a tape control, such as the Teletypesetter unit B (Fig. 1). As pointed out, however, as a feature of the present invention the speed of rotation of the continuously driven rolls B has been. increased from the: normal speed of about 300 R. P. M. to a higher speed of the order of 550 R. P. M. Asa result, the matrices will be released at a much faster rate-than normally, as permitted not only by the steep inclination
