V UNITED STATES PATENT FFIQE 2,112,128 TYPOGRAPHICAL COMIPOSING MACHINE Christian Augustus Albrecht, Berlin, Germany, assignor to Mergenthaler Linotype Company, Brooklyn, N. Y., a company of New York Application‘ November 30, 1936, Serial No. 113,386 7 . ' In Germany June 20, 1936 '2' Claims. (Cl; 199—45) This invention‘relates to typographical com column, consisting of any desired number of posing machines. , . In such machines having’ a plurality of maga zines arranged in superposed relation as’ a col umn, it is usual to employ matrix entrance chan nels (hereinafter called magazine entrances) ca pable of being interchanged. and‘ which, when the magazines are shifted are changed one for an magazines (four being shown in the construction . exempli?ed) which are supported by a suitable frame. The magazine column is guided in the usual manner by means not illustrated in the 5 drawings, so that it can ‘be moved upwardly and. downwardly, perpendicularly to its top and bot tom plates. In order to shift the magazine col other by axial rotation. Such change-over is > rack bars 3 are articulated to it, and pref» 10 effected at the same time as the shifting move erably to the base frame. The rack bars mesh 10 ment of the magazines, so that the rotation and with toothed gears ll, upon the shaft. of which are the change-over of the entrances is performed at secured bevel gears 5 in mesh with bevel gears every magazine shifting operation.’ Such means are therefore only applicable to machines where in a change-over of the magazine entrances is ‘ necessary each time the magazines are shifted. 6 mounted on a shaft 1, and the shaft 1 carries a handle 8 so that by turning the handle, the magazinesrwill he adjustedgto different levels. 15 When changingover from one magazine to anoth er, it’ is necessary for the shaft 1 to be turned to a rotary change-over of the magazine entrances certain extent, (preferably to- the extent of one to a particular magazine arrangement, ithas whole revolution for. changing from one maga 20 been proposed, when using a rack bar andpin zine to the next), and in. order tobe able to lock. 20 In order to allow application of this automatic ion’mechanism for the rotary change-ovento make the rack bar interchangeable and to ?t it to the magazine arrangement in use for the time being. This arrangement makes it necessary 25 however to have different rack bars always avail able and to interchange them when required. The object of the invention is to overcome these disadvantages in the known arrangements, and to make the rotary change-overof the magae’ in zine entrance entirely independent of the maga zine change. According to one embodiment of the invention the locking and the change-over of the magazine: entrances, joined together into a rotatable unit, is effected by the movement of a handle, ‘operating the release of the magazine shift, beyond the extent required for releasing the magazines. ' i In the drawings, one constructional form of the invention is illustrated by way of example, 4:0 and in the said drawings:—- ‘ Figure l is a diagrammatic side elevation of the relevant parts of a matrix composing and line casting machine according to- the inven tion; Figure 2 shows, on a larger scale, the magazine entrances together with the pertinent change over and locking mechanism in the operative po sition; V Figure 3 is a part of Figure 2 and shows the parts after their release, and Figure 4 is the same illustration as Figure 3, but showing the said parts after the change over. In the construction illustrated in the draw ings, i is the machine frame, and 2 the magazine the shifting frame after each shifting opera tion, a disc 9 is mounted upon the shaft 7 and carries on its periphery} a notch, in which engages a ledge l9’ mounted. on a lever 52 ‘adapted to. swing about a stud l i on the magazine frame. 25 Upon a pivot‘ i3 is located a three-armed lever,. one arm ill of which is formed as a handle,_the second arm 65 is articulated to a draw-rod l5.‘ and'third arm ll consists of a segmental por tion, which is adapted to bear against a roller 50 i8 mounted on the lever l2. The lever i2 is also provided with a cam is serving to move a lever 29, ?tted with a roller, which is loosely mounted on the shaft l3 and serves to rock the releasing rods 2| which operate the release of the matrices 35 from the magazine, but which must be moved away from the magazines before the latter are shifted. When therefore the lever I4 is swung clockwise, i. e., when it is raised, the segment I’! bears against the roller 28 and swings the lever 40 12, moving the ledge iii out of the slot of the disc 9 and thereby release. the shaft 1. Atlthe same time the cam 59 acts against the: lever 25 and swings the matrix releasing rods 2i away from the magazine, so that the shifting of the maga- 45 zine can proceed. According 'to the invention, ‘further rocking movement of the said handle I ll causes the re lease and the rotary change over of the maga zine entrances,v and as shown this is effected by 50 means of the rod l6 attached to the lever arm 15. This rod i5 is linked by means of a stud 22 to a double lever 23 Which'is adapted to rock about the pivot 24 located on the lever 25, the lever 25 being itself capable of swinging about 55 2,112,128 ' 2 a pivot 26. On the lever 25 are two abutment screws 2?, 28, which limit the rocking movement of the lever 23 about its pivot 24. Upon the shaft 26 is also mounted a toothed CI wheel 29 which is in mesh with a toothed wheel (ill, fast on the shaft 3| upon which is also ?rmly secured the support 32 for the two magazine en trances 33, 34. The shaft 3| is located. on a swinging arm 35 which is adapted to rock about 10 a stationary stud 36 on the machine frame. On leasing wrods return into their operative position, enabling the compositor to proceed with his work. It should be understood that the principle un derlying the invention consists in arranging means common for the operations of shifting the magazines and of changing-over the magazine entrances, so that these operations can be carried out independently and in particular so that the magazines can be shifted without necessarily changing the magazine entrances. Within the the same arm 35 is also located the stud 26, and a further pivot stud 3'! for a double lever at terms of this principle various modi?cations of the form of the invention described above may one end of which is attached a spring 38 whereas the other end carries a pin 39. The latter, un der the action of the spring 38 is capable of en tering a recess 40 in a disc 4| positively secured be introduced in order to meet different condi tions and requirements which have to be ful?lled, upon the shaft 26. A detent 45 also adapted to‘ engage in the recess 40, is pivotally mounted upon a shaft 24 and by a spring, not shown in the drawings, is pressed against the disc 4|. A stud 42 is also provided on the machine frame to come without departing in any way from the scope of the invention. Having described my invention, I declare that what I claim and desire to secure by Letters Patent is:— 1. A typographical composing machine having 20 adjustable magazines and interchangeable into contact with an abutment 43 on the arm 35 magazine entrances, wherein means common to in order to limit the swinging movement of the the operations of shifting the magazines and arm 35 about the stud 36. changing the matrix entrances are so arranged as to allow said operations to be effected inde 25 The mode of operation of the present arrange ment is as follows:— When the operator desires to shift the maga zines he ?rst swings the handle I 4 in order to release the shifting mechanism. When the lever 30 I4 is raised to a certain extent the shifting shaft ‘l, as previously mentioned is released and the escapement rods 2| moved away from the maga~ zine. Simultaneously, however, and by reason of the pull exerted by the rod It, the arm 35, 35 which is held in its operative position by a very light spring 44, is rocked until the abutment 43 comes into contact with the pin 42. When the parts are in the said position, the shifting of the magazines can be effected in the usual manner 40 without adjusting the magazine entrances. If it is necessary to change-over the magazine en trances, the operator swings the lever I4 clock wise a little further. The pull exerted by the rod l6 rocks the lever 23 about its pivot 24. A rotation of the lever 25 about its pivot 26 does not occur because, in consequence of the engage ment of the locking pawl 45 with one of the grooves 49, it is engaged with the disc 4| and the latter is locked against rotation by the pin 39. When, however, the lever 23 is rocked, the free arm of the lever bears against the pin 39 and raises the latter out of its locking position. The parts then occupy the position shown in Figure 3 pendently irrespective of the number and relative arrangement of the magazines. 2. A typographical composing machine having adjustable magazines and interchangeable maga zine entrances, wherein means for unlocking the magazine shifting mechanism are adapted, upon being moved beyond the extent necessary for said unlocking, to effect a change-over of the maga zine entrances. 3. A typographical composing machine com 35 prising a lock for the magazine shifting mecha nism, means adapted to release said lock upon being operated to a limited extent, a plurality of magazine entrances rotatable as a unit for bring ing one or other into operative position in rela 40 tion to the magazines, and a linkage system, con— meeting said magazine entrances to said releasing means, adapted to rotate the magazine entrances when said releasing means are operated beyond said limited extent. 4. A typographical composing machine accord ing to claim 3, comprising a lock for said maga— zine entrance unit adapted to be released upon operation of said means to the extent necessary for releasing the magazine shifting mechanism. 50 5. A typographical composing machine having adjustable magazines and interchangeable maga zine entrances, wherein common means are em in which the disc 4| has been released so that any ployed for unlocking the magazine shifting mech further movement will cause the locking pawl 45 and the disc 4|, together with the shaft 25 and the toothed Wheel 29 mounted thereon, to turn. After a quarter of a revolution, the stud 39, under the action of the spring 38, drops into the nex notch 49 of the disc 4|; the parts are then in the position shown in Figure 4. The transmission ratio between the toothed wheel 29 and the toothed wheel 30 is such that one quarter of a revolution of toothed wheel 29 causes toothed Wheel 39 to make half a revolution and thereby turn the support of the magazine entrance 180 degrees. In place of the magazine entrance 33, which in Figures 2 and 3 is in the operative posi anism and for effecting a change-over of the magazine entrances. tion, the magazine entrance 34 is brought in operative position by the movement described mechanism and for effecting a change-over oi’ the magazine entrances, said means being capable 70 at one actuation of eifecting both operations con above. When, after shifting the magazines, the handle I4 is released, the rod l6 returns to its original position, the shaft 1 is again locked and the re 6. A typographical composing machine having adjustable magazines and interchangeable maga zine entrances, wherein common means are employed for unlocking the magazine shifting 60 mechanism and for eifecting a change-over of the magazine entrances, said means being oper able to unlock the magazine shifting mechanism alone or independently when desired. 7. A typographical composing machine having adjustable magazines and interchangeable maga zine entrances, wherein common means are em ployed for unlocking the magazine shifting currently.
