DAVID S. KENNEDY, OF BROOKLYN, NEW YORK, ASSIGNOR TO MERGENTHALER LINOTYPE COMPANY, A CORPORATION OF NEW YORK.

' TYPOGRAPHICAL MACHINE.

To all whom it may concern:

Be'it known that I, DAVID S. KENNEDY, a citizen of the United States, residin at Brooklyn, in the county of Kings and tate of New York, have invented certain new and useful Improvements in Typographical Machines, of which the following is a specification, reference being had therein to the accompanying drawing, being a division of original appllcation filed November 30, 1917, Serial No. 204,534.

My invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States to O. Morgenthaler, No. 436,532, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce .the type characters thereon, and the matrices thereafter returned through a distributing mechanism to the magazine from which they started.

My invention, generally speaking, is intended to adapt these machines for handling matrices with characters of greatly increased size or point, such as are used in advertising-matter or. display work. The ordinary linotype machine is not entirely adapted to this class of work for avariety of reasons, and principally because the machine elements are not capable of handling matrices of a size that would be required to carry the enlarged characters. Thus, heretofore, the magazines have been limited in width to that of the keyboard, due to the form of connections between these parts, etc, and hence it is impossible to store all the matrices of a complete font such as I propose to use in any one of such magazines because of its reduced size. The present machine is organized along a different principle and contemplates the use of magazines of such size that each may contain a complete font of the required matrices, involving a radical departure in the form and arrangement of the parts as will appear in. the detailed description to follow.

In the accompanying drawings, for the sake of simplicity, I have shown my improvements 1n connection with a single Specification of Letters Patent. Patented J 11y 27, 192() Original application filed November 30, 1917, Serial No.'204,534. Divided and this application filed March 29. 1819. Serial No. 286,221.

magazine only, but it should be understood that they may be embodied in a machine employing a movable series of magazines,

such as illustrated in my pending application Serial No. 204,534, filed November 30, 1.217, of which the present application is a division, or in any other class of machine to which the invention is applicable. In addition, I have shown my invention only in referred form and by way of example, an obviously many changes and variations may be made therein and in its mode of application and still be comprised within its spirit. Generally speaking, I desire it to be understood that I do not limit myself,

to any specific form or embodiment, except in so far as such limitations are specified in the claims.

Referring to the drawings:

Figure 1 is a side elevation (partly in section) of a portion of a linotype machine having my invention applied thereto;

Fig. 2 is a front elevation of the machine on an enlarged scale;

Fig. 3 is a diagram illustratingthe connections between the keyboard and the magazine;

Fig. 4 is a front View partly in section of a portion of the keyboard and its operating connections;

Fig. 5 is a side elevation of the keyboard broken away at the rear to expose its connections with the escapement operating reels which are shown in vertical section: an

Figs. 6 and 6 are top plan and fron views, respectively, of a portion of the keyboard connections detached.

The matrices X are stored in the magazine A, which is sustained by the supplemental frame g in registration at its lower end with the fixed throat C communicating with the usual front plate or raceway C and. at its upper end with the magazine entrance F leading fro-m the distributor F.

The matrices are released from the ma azine by a single series of escapements 2 located in the throat C and actuated by reeds C and each comprising, as usual, (Fig. 1) a pivoted lever and two pawls which are projected thereby alternately into the throat in effecting the release of the matrix. The arrangement and operation of the escapments are the same as shown and described in my previous Letters Patent No. 1,115,211, and therefore require no further description here. It may be stated, however, that the action of the escapements is such that they hold the lowermost matrices in the magazine and after their actuabar G as a pivot tolocate the magazineabove the assembling devices.

The parts so far described, except as hereinafter pointed out, may be of any well known or approved construction or, as illustrated in the parent application above referred to. As before stated, the present invention is directed to a new relation between and in the form of the magazine and the assembling devices as will now be described.

By referring to Fig. 2, it will be seen that the magazines are much wider than the keyboard which, in prior machines, has been of the same width, and in addition, they are made much shorter than those ordinarily employed (see Fig. 1). By thus shortening the magazines, the weight of the parts is materially reduced and the machine rendered more compact than if the magazines were of full normal length. I have found that, in respect to most of the characters, there is no danger of the supply of matrices becoming exhausted because of the short magazines, and as to those more frequently used, I have allotted two magazine channels to each, providing mechanism whereby the .matrices may be drawn alternately therefrom. I also propose to store the matrices in the magazine in the regular order and to arrange the finger keys in the keyboard in the same order, as customary. Due to the increased width of the magazine as compared with that of the keyboard, it is obvious that the usual connections between these parts is unsuitable for the present arrangement, as it is well known that ordinarily each finger key cooperates with its corresponding matrix column through a train of connections lying in a vertical plane which'passes substantially through the key and the matrix column. In accordance with my invention, 1 have provided a system of connections between the finger keys and their corresponding matrix columns such that the keys may stand in different vertical planes from their corresponding channels, although as to some of the keys this relation has been maintained.

The general arrangement of the parts is represented diagrammatically in Fig. 3,

ond tier of keys (s to u); while as'to the third and fourth tiers (c to j) the keys lie substantially in the same planes as their escapement reeds C being connected thereto in the usual manner. All the other tiers of finger keys are connected to their respective groups of escapement reeds by offset connections, the distance between each tier of keys and the corresponding group being greater and greater as the last tier is approached.

Referring now in detail to the construction of the parts, the magazine is provided with as many escapements C and actuating reeds C as there are matrix columns in the magazine. The escapement reeds C are operated by the yokes C arranged in two different banks and provided with cams or eccentrics C adapted under the influence of the trip dogs or triggers C to cooperate with the underlying power-driven rolls C in' the well known way. The dogs C are connected as usual to the upper ends of vertical slides G which are suitably supported in the framework and are adapted to be raised by the manipulation of the finger keys C of the keyboard C The two tiers of finger keys bearing the letters c to j are connected directly to the corresponding slides C so that such keys and their connections stand in the same vertical planes as their respective escapement reeds, as heretofore. The keys of the remaining tiers, however, are attached at their rear ends to short idle slides C which are connected to the correspondin cam releasing slides C located at a di erent point in the width of the keyboard, the keys thus being oflset from the matrix columns which they control. The connection between the slides C and C in the present instance is in the form of U- shaped straps or bails C whose parallel arms engage in notches or recesses in the rear edges of the slides. By means of this connection, therefore, a finger key occupying its usual place in the keyboard is capable of controlling the operation of its cam yoke located in the plane of the escapement reed or matrix column which is situated remote from the key. Preferably, and as shown,

. from one side of the keyboard to the other.

It will be noted that the bails vary in length in the different groups correspondin to the varying distances between the tiers o finger in Figls. 6 and 6. This group arrangement of t e bails and escapement reeds is advantageous fora variety of reasons, not only reducing the cost of manufacture but greatly simplifying the construction. The six pivot rods C are common to all the groups of connecting bails, each rod giving support to the corresponding bails of all the groups arranged at the same level.

These pivot rods with the bails thereon are mounted in a box-like structure comprising the longitudinal parallel plates P secured to- 15 gether at their opposite ends by the cross plates P The pivot rods C are fitted into the side members P while the arms of the bails C project forwardly throu hout slotted openings in the front plate to 20 make engagement with the key actuated slides, the openings P being of such character as to permit a limited rocking of the bails such as is uired in communicating the movements of t e slides C to the cam z5.'neleasing slides C As thus arranged the box-like structure P, P, with the contained bails and pivot rods, may be readily applied 1 to or removed from the machine as a unit, the loose engagement betweenthe bails and so the actuating slides C and C being made and broken as the unit is applied or removed. When in place the unit is fixed to the machine by means of screws P 'passin through -extensions in the front plate P o the supporting structure. If desired, pointed pins P may be employed to aid in locating the parts in their proper position (Fig. 6). In this construction, it may be noted that the pivot rods 0 are capable of being with- 40 drawn endwise to disassemble the parts, the rods being held in'place by a locking strip P engaging in circumferential grooves in the exposed ends of the rods.

If desired, the bails Q could be applied 45.at a different point in the connections between the keyboard and the magazine. Thus, instead of being arranged between the fin er keys C and the power-operated cam yo es C", as shown, they could be arranged between the cam yokes and. the escapement-reeds C in which event the yokes would be operated directly by and located in the planes of the corresponding finger keys (as in the case of the two-tiers c to j) and the idle slides 56 C would be arranged above and in the planes of the yokes and their reciprocations transmitted through the bails to the escapement reeds.

As before indicated, I propose to store the 80 more frequently used matrices in duplicate channels of the magazines, such as those bearing the characters e, t, a, o,i and n (represented in the first tier of finger keys), and em, en and th (represented in the sixth, seventh and eighth tiers of keys, respectively).

' added to the The ma azine is therefore provided with so many a ditional channels and a corresponding number of escapements C and actuating reeds C it being noted by referring to the diagram of Fig. 3 that six reeds have been tier of finger s, and one added to each of the groups represented by the sixth, seventh and eighth tlers of keys. Theescapement reeds associated with all the duplicate channels are shorter than the remaining reeds, and are supported in the framework some distance above the operating cam yokes-C, as clearly shown in Fig. 4. Interposed between these escapement-reeds and the cam yokes are short rods or sections'D supported with their lower ends in permanent en aging relation to the cam yokes C and w ich are arranged to be moved laterally at their upper ends to be connected alternately with first one and then the other of the two sets ofoverlying escapement reeds. Thus, for the characters e, t, a, o i-and 11, there are six intermediate rods 15 to cooperate with the twelve escapement reeds serving the magazine channels wherein the matrices bearing these characters are stored, so that when the rods are shifted to the left they will operate everv other escapement reed of the group, and when to the right the intermediate escapement reeds, thus causing the matrices to be delivered alternately from their respective duplicate channels. The same arrangement is true as to the characters em, on and th, except that for each there is but one adjustable rod D employed to make the alternate connection of the corresponding finger key with the two associated esca ement reeds. 7

he lateral adjustment of the rods D as lgroup represented by the first above described is effected by means of a longitudinal shiftable bar D formed with laterally projecting guide or comb plates D wherein the upper ends of the sections engage. This bar is supported in the ma; chine frame by a pin and slot connection D and a sliding plunger D, which latter is loosely attached to the upper end of an operating lever D pivoted centrally as at D to the frame. A spring D acting on the lever above its pivot tends constantly to shift the bar D to the left and to maintain the lower end of the lever in engagement with a rotatable face cam D having alternate risers and depressions D and D. See Rogers U. .8. Patent No. 1,188,730. As a result of this construction, when the lower end of the lever D engages in one of the depressions D of the cam, the bar D is shifted to and maintained in its position to the left, presenting the rods D in operative I 55 zines, but it enables those parts to be manurightmost escapement reeds.

its position to the right, causing the rods D to be presented in operative relation to the In other words, the rotation of the cam D acts through the connections described to shift the rods D alternately to the right and left to connect different escapement reeds with the cam yokes and their controlling finger keys.

he rotation of the cam D is effected by means of an attached ratchet wheel D having as many teeth as there are risers and depressions on the cam and adapted to be rotated by a reciprocating pawl D. The pawl D is carried by a pivoted bell crank lever D connected by a link D to the bring either a riser or depression thereof into action, so that by the repeated operations of the assembler a change will be effected between the duplicate magazine channels.

The distributer F is supported in thesecalled distributer bracket Z, which constitutes the upper portion of the main frame. Ordinarily, this bracket is of U-shape form with its two arms substantially straight and parallel and pointing upwardfor the attachment thereto of the distributer parts. In the present instance, the two arms are extended forwardly from the connecting or base portion of the bracket, as shown in Fig. 1, so as to locate the distributer nearer to the front of themachine and at a lower level than customary; This new location of the distributer thus adapts it to cooperate with the'improved magazine, which as previously stated is of less than normal length.

The improved wide and short magazine herein shown and described presents many advantages: It not only reduces the weight of the parts because of its shorter length and the fewer matrices employed and thus permits the interchange of magazines with the same ease and facility as ordinary magafactured and sold at comparatively small cost, thus permitting a large number of magazines with different fonts to be kept on hand for ready interchange in the production of the varied forms of printed matter desired. In addition, the construction of the machine itself is greatly simplified and rendered more compact than would be possible in the use of magazines of ordinary or full length. Thus, the width of the magareductionin the width of the magazine en-.

trance and in the length of the distributer, which latter in their new relations are not much greater in extent than the assembling devices themselves. These and various other advantages will be apparent to those versed in the art.

As previously stated, I have shown my improvements merely in preferred form and by way of example and as applied to the particular kind of-machine described, but it will be obvious that many modifications and alterations will readily suggest themselves to those skilled in the art without departing from the scope of the invention.
