8 Claims.

My invention relates to improvements in a typographical machine.

One of the objects of my invention is to improve typographical machines which have a plurality of matrix magazines, for supplying different founts of type.

Another object of my invention is to improve a typographical machine having a plurality of magazines, in which the matrices of the different founts have corresponding combinations. This type of typographical machine is known in the trade as Mergenthaler Linotype No. 8 but it is to be understood that my improvements relate to all types of typographical machines, having a plurality of magazines.

Another object of my invention is to provide new and improved means which prevent the changing of the magazine unless the last line of matrices which has been set, has been fully dis- 1 tributed before the magazine is changed.

Another object of my invention is to generally improve the operation of a typographical machine which has a plurality af magazines, so as to prevent the matrices from entering the wrong magazine.

Another object of my invention is to prevent the changing of the magazines, while the matrices have not yet reached the distributor bar, so that the magazines cannot be changed while the matrices are retained on the second elevator bar, or in the distributor box.

Another object of my invention is to provide improved means for preventing the changing of the magazines, while the matrices are on the distributor bar.

Generally speaking the improvements make it impossible to change the magazine, until all the matrices have been caused to enter the magazine which is being shifted.

Other objects of my invention will be set forth in the following description and drawings which illustrate a preferred embodiment thereof, it being understood that the above generel statement of the objects of my invention is intended merely to generally explain the same and not to limit it in any manner.

For many years it has been a frequent experience to have the operators of typographical machines of the multiple magazine type, change the magazines before all the matrices which belong to said magazine have entered the same. This has been a frequent source of serious errors in printing, and this has also caused the jamming of the machine, and the loss of a great deal of time.

According to my invention a plurality of controls is provided, which prevents the changing of the magazines, unless all the matrices are properly located in their respective magazines.

In order to clearly illustrate my improvements, I have illustrated a number of the essential parts of a well known typographical machine (Mergenthaler #8) but the improvements generally apply to any type of typographical machine.

In the type of machine illustrated herein, there are three magazines 1, which are mounted upon a common base la. Said base 1a is mounted upon a vertically movable member 11), which is moved up and down by the operator, in the well known manner, in order to change the magazine.

Referring to Figs. 1, 1a and 6, the machine is provided with distributor screws or worms 3, and these are of the usual type. These distributor screws 3 operate to feed the matrices M along the distributor bar 4, in the usual manner. The distributor screws 3 are actuated in the usual manner by a. conventional drive 2, which is operated by the usual belt 2a.

Referring to Fig. 2, the magazines are shifted up and down in the direction parallel to the arrow 18, in order to change a magazine. The frame of the machine, including the various frame arms is generally designated by the reference letter F.

Referring to Figs. 2, 7 and 8, the base 1a is provided with a suitable number of slide bars 19, which are of the well known type. As shown in Fig. 3, each said bar 19 is connected to the base 1a by means of suitable bolts, and each said bar 19 is provided with a pair of cutouts or recesses 20 and 20a.

Magazine locating bars or bolt-bars 17 are provided in the usual manner and each of these bars 17 is provided at each end thereof with a head or enlargement 21. When said heads or enlarge ments 21 enter the top cutouts 20a, the bank of magazines is in its bottom position so that the top magazine 1 is in the operative position. When these heads or enlargements 21 enter the recesses 20, the intermediate magazine 1 is-in the operative position. When these heads or enlargements 21 abut and engage the bottom surfaces of the bars 19, the bank of magazines is in its top position, and the bottom magazine 1 is operative.

The magazine locating bars 17 are held in their operative positions, in which they prevent the changing of the magazines, by means of springs 22. Said springs 22 are suitably connected to the frame of the machine and to studs which project from said bars 17.

Referring to Figs. 6 and 8, one of the magazine locating bars 17 is provided with a laterally projecting stud or pin 39. The guard-lever 36 for the distributor screws 3, is pivotally connected to the frame of the machine, by means of the pivot member 37. The movement of said lever 36 in the counter clockwise direction, is limited by the pin or banking screw 36a, which is suitably connected to the frame of the machine.

Referring to Figs. 1, 6 and 7, thescrew guard 31 is of the usual type, and this is connected in the usual manner to the bottom ends of arms 32, which are turnably mounted upon a rod 33. The rod 33 is connected to arms 34, which form part of the frame of the machine. Tension springs 35 operate to maintain the guard 31 against the upper end of lever 36.

The bottom of the guard lever 36 is provided with a cam-shaped extension 38, which may be integral with said lever 36, or may be suitably connected thereto.

As shown in Fig. 6, said extension 38 has a tapered face which positively engages the pin 39 of the locating bar 17.

The lever 36 therefore positively locks the bar 17 in position, thus making it impossible to change the magazine, as long as there are any matrices M remaining upon the distributor bar 4.

The face of the extension 38, which contacts with the pin 39, may have a veryslight taper and be almost perpendicular to the bars 17 so as to diminish the leverage of the pin 39 against the lever 36. This construction makes it impossible for the operator to force the bars 17 out of the position shown in Fig. 6, while there are matrices upon the bar 4. When the matrices have been cleared from the bar 4, the operator can turn the guard lever 36 to the inoperative position shown in Fig. 8, by shifting the bar or bars 17.

It is to be understood that there are a number of the bars 19 and 17 in the device, but that it is only necessary to provide a single guard lever 36, which is associated with one of said bars 1'7.

It has been proposed to utilize a distributor screw guard of the type of member 31. However in constructions of the present type the plate 31, which is flexible, can be bent or jammed against the matrices so that the magazine can be changed while there are matrices remaining upon the bar 4. However the construction illustrated herein causes the screw guard 31 to have a large movement when the lever 36 is actuated, so that the end of said guard 31 is underneath the central plane of the distributor position shown in Fig. 8. It is therefore impossible for a careless operator to manipulate the bolt-bar 17 to such an extent as to spring the guard 31 and'to remove the bolt-bar 17 to its inoperative position, if there are matrices on bar 4.

Referring to Figs. 1 and 1a, the device is provided with a second elevator bar 5 of the usual type, having the usual head 5a, which is brought into alignment with the distributor bar 4 when said bar 5 is raised to the position shown in Fig. l. In order to shift the matrices M from the head 5a to the distributor bar 4, mechanism of the usual type is employed, as the invention consists of a special control which is later described. The mechanism for shifting the matrices from the head 5a to the bar 4 comprises a lever 6 which is connected to a link 7, which is pivotally connected at 8 to ablock or slide 14.

Fig. 1 shows the dotted line position of the block 14 when the shifting mechanism is about to shift the matrices from the head 5a to the bar 4. In the full line position of the slide 14 which is illustrated in Fig. l, the matrices have been completely shifted through the distributor box 11.

Referring to Figs. 1 and 2, the slide 14 is connected to a bar 9, which is connected to a head 10. The head 10 pushes against the matrices M in order to shift them on to the bar 4, and to force the matrices through distributor box 11.

Referring to Figs. 1a and 2, a separator bar 12 of the usual type is provided, and this is provided with the usual separator or spacer 12a, so that the matrices are separated as they are shifted out of the distributor box 11, so that the spaced matrices M are engaged and fed along the distributor bar 4 by the distributor screws 3. This spacing mechanism is of the usual type.

Referring to Figs. 2 and 3 a control lever 23 is provided with a bottom extension 23b and with a top extension 23a; The bottom extension 23?) enters an opening in one ,of the bolt-bars 17, so that said bolt-bar 17 cannot be shifted out of its operative position, as long as said extension 23b is in the opening of said bolt-bar. The control lever 23 passes through and is adjustably held in a bearing member 24. Said-bearing member 24 has a shank 25 which abuts a plate 26, which is suitably connected to the frame of the machine by means of fastening members 27. The shank 25 is turnably held upon the plate 26, by means of a pivot member 28. Stop pins 28s are provided for limiting the turning movement of the control bar 23. A spring 29 has one end thereof connected to the plate 26 and the other end of said spring 29 engages said lever 23 so that said lever 23 is normally held in the operative or full line position which is illustrated in Fig. 3.

When the slide 14 is moved to the full line position shown in Fig. l, in which position all of the matrices have been moved onto the bar 4, the bar 9 engages the upper extension 23a (as shown in Fig. 1) so that the extension 231) releases the associated bolt-bar 17. Fig. 3 also shows how the bar 9 engages the extension 23a, which is .L-shaped, so as to turn the control lever 23 to the inoperative position. However the lever 23 does not fully release the bolt-bar 17 as long as any of the matrices are still on the head 5a or in the distributor box 11.

The movement of the slide 14 is limited by a stop30.

The second elevator bar 5 is provided with the 150 usual spring 15, which is connected to a yoke 16 of the head 5a, said head 5a being turnably mounted upon the bar 5 in the usual manner.

As shown in Fig. 4, the upper end of the boltbar 17 is provided with a bevelled surface 170., in order to facilitate the clearing of the bolt-bar 17 by the extension 23b.

It will be noted that both sets of controls i1- lustrated herein cooperate in order to prevent the changing of a magazine, unless and until saidmagazine has received all its matrices.

It has heretofore been proposed to have the pin 39 engage the bottom surface of control lever 36, and to have said bottom surface make a very small angle with the longitudinal axis of bolt member 17, and such a construction has been extensively used for many years. However, if a careless operator moved the bolt member 17 away from its operative position, the pin 39 would ride along and jam against the bottom surface of lever 36 without turning the same substantially especially if said lever 36 were loosely mounted upon its pivot. The bolt 17 could thus be withdrawn from its operative position even if matrices were mounted on the distributor bar. Likewise, such constructiton did not move the guard 31 in a lateral path of suflicient length towards the bar 4, so that the guard 31 could bend against the matrices, thus permitting the release of the bolt. According to my invention, the lower branch of lever 36 is made sufficiently long, so that the path of movement of said guard plate 31 is long enough to allow for any bending of said guard plate, thus pre venting release of bolt 1'7 unless bar 4 is clear of matrices. Likewise the pin 39 abuts lever 36 above the bottom surface thereof, so that pin 39 cannot slip along or" jam against lever 36. The parts are so dimensioned and shaped as to cause the guard 31 to substantially assume the position shown in Fig. 8, before pin 39 contacts with the under-surface of lever 36.

Of course, the same result could be secured if the pin 39 contacted with a bottom surface of lever 36 which was sharply inclined with re spect to the longitudinal axis of bolt 17. The pin 39 preferably remains in contact with the bottom part of lever 36, when the bolt 17 has.

been fully withdrawn to its inoperative position.

In the embodiments shown in Figs. 10-12, the member 23 and its appurtenant parts are eliminated, and a lock is provided for the screw guard plate 31, which prevents its release from the position shown in Fig. 6, unless all the matrices I have been pushed through the distributor box 11, so that they are engaged by the screws 3.

As shown in Fig. 11, a plate 60 is rigidly connected at 61 to the frame of the machine. A pawl or looking member 62 is pivotally connected to the plate 60, by means of the pivot member 63. A blade spring 64 is connected to the plate 60 by means of the member 64a and this spring 64 bears against a pin 6'7 which projects from the locking member 62, so that said locking member 62 is turned in the counter clockwise direction, until said member 62 abuts a stop pin 65, which projects from the plate 60. For this purpose a suitable recess is formed in the edge of the pawl 62.

As shown in Fig. 12, the recess 66 is of substantially triangular shape.

As the slide 14 reaches the end of its movement, it contacts with the upper end of the pawl member 62, turning the same in the clockwise direction, so that the member 31 is released, thus permitting the changing of the magazines. However the magazines cannot be changed until all the matrices have been pushed through the distributor box 11.

Of course the guard plate 31 cannot be moved away from the position shown in Fig. 6, until the matrices, all of which have been delivered to the distributor bar 4 so that they are engaged by the screws 3, have been caused to enter the proper magazine.
