TYPOGRAPHICAL ASSEMBLING AND DISTRIBUTING MACHINE.

Application filed October 5, 1926. Serial no. 139,721.

My invention relates to typographical machines of the kinr in which circulating matrices are released from a magazine anc. sembled in line and then presented to mold in which the print ng type is cast against the line of matrices, the matrices subsc quently being distributed to their individual channels in the magazine from which they were released.

Particularly, it relates to improved means for conducting the matrices into the magazine channels and releasing them therefrom, with the objects in view of rendering these ope 'ations more positive than heretofore and also simplifying the machine and increasing the capacity of the magazine without increasii'ig its size. Heretoforc the magazines of linotype machines have been made about one-third wider at their receiving end than the accumulative thickness of the stored matrices would actually require. The necessity for the excess width of the magazines their receiving end has been due to the fact that the matrices in dropping from the distributing har could not clear the lower distributor screw; therefore entrance partitions were provided equal in number to themagazine channels, the resultant channels between such partitions being of su'liicient dimensions to receive the matrices following their interference with the lower distributor screw. It is the width at these partitioned entrance channels that has determined the width of the magazine at the receiving end, and this invention conten'iplates eliminat ng the entrance partitions and substituting therefor opposed-groove channels similar to those in the magazine and in continuation thereof. lVith such construction. the magaa des may he rectangular in shape instead of the usual trapezoidal form, and the channels therein may be parallel, thus greatly reducing the manufacturing cost of the magazine. Also, the matrices will more readily enter, travel through, and escape from the parallel channels than in the case of converging channels; the matrices will he distributed quicker by reason of the reduced width of the magazine at its receiving end, and addise tional channels may be added to the magazine without increasng its weight. Farah lelino' the channels of the ma az ne also renders feasible the form of matrixescape ment of this disclosure, and this escapement in tiu n renders possible the simplification of the keyboard mechanism. An example of the partitioned entrance above referred to as eliminated may be found in the patent to O. Mergenthaler, No. 436,532.

In the accompanying drawings:

Fig. 1 shows the usual trapeziform maga zine overlying the rectangular form of magazine shown in connection with the principal figures of the drawings, and'illustrates how the magazine may be widened at its lower end and narrowed at the receiving end in order to provide for additional channels without increasing its total area and weight.

Fig. 2 shows the usual trapeziform magazine between a rectangular magazine of less size but with an equal number of channels, and a rectangular magazine as wide as the trapeziform. magazine at the receiving end but capable of containing one-third more channels than the usual trapeziform magazine.

F ig. 3 is a vertical section through the distr'hutor, magazine and delivery throat ofa linotype machine in which the matrices are delivered in vertical position to the entrance channels and thus necessitating a curved entrance channel. This view shows the application of my distributor improvements and a form of my improved escapement to a machine thus constructed.

Fig. 17 is a continuation of Fig. 16 and includes distributor-entrance channels to cooperate in connnon with the magazines of either Fig. 15 or Fig. 16.

Fig. 18 isa. view of the left-hand side of the upper portion of Fig. 17, showing a device for preventing wrong-font matrices from entering the regular channels of the magazine.

Fig. 19 shows the keyboard of Fig. 6 in lowered and tilted position.

Referring to Figs. 3 and 4, the matrices X are as usual conveyed by means of the distributor. screws 1, 2 and 3 along the distributor bar atuntil they reach a point above their individual channels. The omission of a combination of ribs 5 on the bar 4 above any entrance channel indicates the retention of a corresponding combination of teeth on the matrices destined for such channel; therefore the matrices are released from the rail when their retained combinations clear the ends of a combination of ribs on the bar. As commonly constructed, the matrices have their screw-engaging lugs flush with their forward or lead side as they appear when traveling on the bar i, and their distributing teeth flush with the opposite side, and since matrices of one font may exceed in thickness those of another font. I terminate the distributing combinations on the bar 4: with reference to matrices of the thickest font; therefore matrices of thinner fonts will not immediately enter their channels when released from the bar 4, but will be supported by means of their upper lugs on rails 7 and 8 until they reach opposed grooves formed on facing sides thereof, as more fully explained in my co-pending application Serial No. 546,38? \Vith reference to the rails 7 and 8, this present invention is concerned principally with the angles of the grooves 7 and 8 relative to each other and relative to the matrices while suspended from the distributor bar. It will be noted that the outer grooves 8 are continuous with similar grooves 9 in the magazine entrance 9 and that these grooves 9" are in continuation of the grooves 10 in the magazine 10; but the inner grooves distributor screw 3. The angle of the outer grooves 8 relative to the suspended matrices is such that the lower, outer lug, X of the matrices will clear the ribs separating the grooves 8, while the matrices are being conveyed on the distributor bar 4-; when the matrices reach their individual channels their lower inner lugs X immediately enter the inner grooves 9 and both upper lugs X", X enter the grooves 7 8. The inner grooves 7" are parallel with the opposite grooves S but are of receding depth to avoid interference with the horizontal travel of the matrices; hence both upper lugs on the matrices will remain in their channels except as the inner channel is interrupted by the lower distributor screw. A short distance below the lower distributor screw the grooves 9 in the magazine entrance channel approach each other, as at 9, therefore before the inner upper matrix lug X leaves its groove 7" both lower matrix lugs will be fully engaged in their channel 9 and the lower distributor screw will prevent the upper outer lug X from leaving its channel. In order that the upper lug X of the matrices may not enter the groove of the lower screw this screw is of reduced diameter with the result that the groove is made steeper than usual so that its vertical measurement is less than that of the matrix lug X and will be bridged by the lug when passing the lower screw. (See Figs. 4: and 17.) It will be apparent that the channel angles as thus described and illustrated are such that only one matrix lug at a time may remain out of engagement with its groove, and the simultaneous engagement of three lugs with their grooves will retain the matrix in such position that the disengaged lug will enter or re-enter its groove at the appropriate time. This arrangen'lent makes possible the elimination of the usual magazine entrance partitions and a consequent reduction in the width of the magazine as explained in the preamble of this specification and in the description of Figs. 1 and 2 of the drawings. Only a sullicient number of the partitions 9 are retained to space apart the inner and outer channel plates of the magazine entrance 9. The outer grooved rail 8 is secured to suitable brackets 11 movable are of necessity interrupted by the lower Ill) With a shaft 12 mounted on the distributor beam 13 in order that the rail 8 may be moved outwardly and upwardly to provide access to the matrices or other parts. A detent 14 serves to hold the rail in a selected position. The foregoing description of Fig. 3 also applies to Fig. 5 so far similar reference numerals with different exponents are employed to designate corresponding parts. But it will he noted that in Fig. 5 no magazine entrance channel is employed, and its elimination is made possible by the improvements above described in connection with the rails T and 8. In Fig. 5 the distributor bar 1 is arranged at a greater angle than the magazine in order that the initial drop of the matrices may be fast enough to cause them to enter the magazine without interfering with a following matrix. This angle of the distributor bar may be more or less according to requirements, and in Fig. 10 it is shown centered in the same plane with the magazine.

The preceding description of Fig. 3 also applies to Fig. 9, in which corresponding reference numerals with different exponents designate similar parts. But in Fig. 9 the grooves 7, 8, in the rails are curved to better eo-operate with the grooves in the magazine entrance, which is pivoted at its upper end and movable at its lower end from one to another of two magazines in manner similar to that disclosed in my U. S. Patent No. 1,266,970.

The principle of my improved matrix escapement resides in providing a pit or perforation adjacent the discharge end of each magazine channel, into which pit the forward or shorter lug of the matrices may enter. A simple form of the escapement is shown in Fig. 3 in connection with a singlemagazine type of machine. In this example the perforations take the form of notches formed in series in the edge of the assembler entrance throat 16. Each notch is occupied by the end of an escapement reed 17 and as the reeds are actuated in usual manner by manipulation of a keyboard, the lug X of the matrix is raised out of engagement with the notch 15 and the matrix is permitted to escape from the magazine, the following and longer lug X bridging the notch 15 in stead of entering therein. The forward lug of the following matrix will then enter the notch and be retarded until likewise released. By holding the reed 17 in raised position all or any number of the matrices in a channel may be caused to escape from the magazine, as when spacing or leadering out a line in the assembler. In order that the ribs 18 which separate the channels 10 of the magforward matrices in the magazine. For the single magazine type of machine a suitable locking bar 19 may be provided to prevent spillage of the matrices when the magazine is removed from the machine. A rod 20 may be changed from rear or front positions heneath side arms 21 mounted on a pivot rod 22 and carrying the locking bar 19. In Fig. 3 the rod 20 is shown in position to lock the matrices in the magazine, and in Fig. 8 it is shown in unlocking position.

Another simple adaptationof my escapement principle applicable to certain types of machines is shown in Fig. 8 and consists in dividing the assembler entrance throat into a series of pawls 28, one in front of each magazine channel. A centrallypivoted lever 24 is associated with each pawl 23, and as the operating reeds 17 are raised an associated pawl 23 is depressed from in front of a corresponding column of matrices and the forward matrix passes over the pawl to assembling position. The weight of the reed 17 restores the pawl while the matrix is passing thereover and the following matrix is stopped as explained in the description of Fig. 3. A continuous plate 25 integral with the i'nagazine provides a floor for the series of pits in which the forward lugs of the matrices rest.

In certain types or models of machines the magazines are arranged in a column as in Fig. 5, the column being movable in order to bring a selected magazine to operative position. For this type of machine I provide the escapement perforation 26 through each channel of the magazine. In connection with the upper and middle magazines of Fig. 5 the escapement reeds 17 act directly upon the matrices. But where the channels of the magazines are crowded or arranged in pairs for accommodating two fonts of matrices I prefer to employ a thin escapement element 27 to be acted upon by the reeds 17". \Vhen the magazines contain two fonts of matrices (Figs. 13 and 14) the contact points 27 of the escapement elements are placed fore and aft on alternate escapements, those having the forward posit-ion controlling one font of matrices and those having the rear position controlling the other font. By moving the operating ends of the escapement reeds from one to another of the two series of contact points 27 :1 selected font of matrices is brought under control.

In order that both types of escapement shown in Fig. 5 may be employed in the same machine, I provide a keyboard (Figs. 6 and 19) which may be raised and lowered according to whether or not a magazine having the escapement elements 27 is in operative position, the reeds 17* moving with the keyboard. At each of its ends the keyboard 29 is provided with studs 30 which rest on iiu ill

"lior any purpose.

straightline levers 31 pivotally connected to a slide supported on the stationary keyboard support 28. Links 33 are pivotally connected at their lower ends to the stationary frame 28 and at their upper ends to the levers 31. The slide 32 is provided with a rack, and is controlled by means of a gear 36 having an operating handle 37. \Vhen the keyboard is in raised position as in Fig. 6 a latch 38 holds the slide against forward movement, and when this latch is raised and the handle 37 moved rearwardly, the slide 32 moves forward, being supported by means of slide blocks 3i resting on a track 35. In its forward position the slide 32 is stopped by contact of the slide block 3% with a shoulder 39, and when in such position the upper ends of the supporting levers 31 will have been lowered and the keyboard correspondingly lowered to associate the reeds 17" with the escapement elements 27 when in operative position relative to the assembler entrance throat l6. \Vhen thus lowered the forward end of the keyboard rests on opposite cams 40 which are controlled by a handle t1 and serve to tilt the keyboard about the rear supporting points 30 for the purpose of placing the upper ends of the reeds 1T beneath one or the other of the two series of contact points 2, selectively, according to the matrix font selected for use. When tilted as shown in dotted lines in F ig. 19 the reeds 17 occupy the position shown in Fig. 11, the other position being shown in Fig. 12. The reeds li' are guided at their upper ends in a suitable perforated plate =12 and at their lower ends in a guide 43. These upper and lower guiding and spacing members are secured to side members 44 which are in turn held against the sides of the keyboard by means of latches 15 in a manner such as to permit the ready removal of the reeds 17 from the keyboard Also, the keyboard as a whole may be readily lifted from position in the machine and a keyboard having a dill'erent number of keys substituted therefor, for use in connection with a magazine having a corresponding number of channels. In Fig. 15 is shown a keyboard having 120 keys and in Fig. 16 a keyboard having 78 keys.

.ieferring to Fig. l t, it will be noted that the contact points 27 are bent alternately to the right or left according to series, so .that the reeds 17" may engage a selected series without any sidewise adjustment for that purpose. Instead of thus bending the escapement elements, the eseapeinent reeds may be split and forked as shown in Figs. l1, l2, and 13 with the lines of the forks olfset in opposite directions from the body of the reeds. In Fig. 11 the reeds as thus formed are shown beneath one alternating series of escapements, and in Fig. 12 they are shown beneath the other alternating series. Vith the reeds thus shaped the same result would be obtained if the two sets ol, escapements were of like shape.

ltel'erring to Fig. 17. it will be. noted that the distributor entrance rail 7 is provided with notches 7" equal in number to the channels of the magazine of Fig. 16, but has associated with it a magazine having a fewer number of channels. ln order that both kinds of n'iagrazines may he em iiovcd in connection with a single type of rail 7, certain ol the channels of the irizu 'azinc havinp the lesser number of channels are bent at their upper ends as shown in Fifi. 17 so that they are positioned to aline in continuation of those channels 7" of the rail 7 which are intended to be operative in connection with a ll'lilfl'tiiiill} having the fewer number of channels. It will be um bod that such a magazine is intended to contain the large.- s es of matrices, and when the matrices are stored in the magazine in that portion thereof where the channels are parallel, no waste space need exist between the successive columns of matrices.

It frequently nec ssary in the course of composition to employ special matrices or wrong-font matrices not intended to enter the storage channels of the magazine in use. Such characters are usually inserted by hand in the assembler (not shown) and after the casting operation are either removed by hand from the line prior to distribution. or. ii notched for such purpose, are permitted to travel across the entire length of the distributor bar and enter a special receptacle beyond the magazine channels. 1n the la ttcr case their font notch X must correspond in position with the similar notch of the font in use, otherwise the special or wron; ='lont matrices could not pass the usual fonl.ilistinguisher element, corresponding with the similar element A of Figs. 17 and .18 of this invention. In order that such special or wrong-font matrices may be automatically returned to the receptacle or channel in which they are kept, and this without necessitatin; their travel across the length of the distributor bar, I provide the font-distinguisher point A pivoted between the side plates 10 of themagrazin and in advance of the magazine channels. Matrices having the font notch X in regular position will clear the distinguisher point A and enter their magazine channels, but the special matrices having the font notch omitted, or wrong font, or n'iatrices having their font notch differently positioned, will tilt the distinguisher point A about its pivot B. under the urge of the distributor screws. \Vhen this occurs a section 4-" of the distributor bar is raised into a clearance J and above the path of the distributing combinations X on the matrices. The matrix will therefore be disengaged from the distributor bar 4 and will drop into a spiral channel P and thence either through a tube N or an extra magazine channel 0 according to the position of a switch element K, which may be controlled by means of a handle M on the outside of the magazine, the switch and handle being pivoted in common on a pivot shaft L. A lever C is pivoted in common with the distinguisher point A on the pivot shaft B and the two elements are joined together outside the magazine by means of a pin D for joint movement. The outer end of the lever C actuates an arm F which is connected by means of a hinge pin G to a lever H carrying a link I from which is suspended the movable section 1 of the distributor bar. A stop pin E serves to limit the return movement of the parts and thus locate the movable section 4 in alignment with the main portion of the distributor bar 4. Through the connections as described, a wrong-font or special matrix will cause the movable sec tion of distributor bar to be raised and the matrix will enter the special channel P as explained. Any suitable receptacle or container may be employed at the termination of the tube N, and when occasion requires, as when repeatedly using a certain special matrix, it may be diverted into the magazine channel 0 and controlled for release by a special keyboard key or by manually lifting it out of the escapement perforations 26 of this invention.
