To all whom it may concern:

' Be it known that I, HEINRICH DEGENER, residing at 26 Hollmannstrasse, Berlin, Germany, a subject of the King of Prussia, German Emperor, manager, having invented certain new and useful Improvements in or'ltelating to Line Setting and Castlng Machines, do hereby declare that the following is an exact specification of the same, being a division of an application filed by me on the 22d day of August, 1910, Serial No. 578,459.

This invention relates to improvements in line setting and casting machines of the known Mergenthaler type, and has particular reference to the fixing or locking of the matrix line in the casting carriage.

The accompanying drawings show by way of example constructions according to this invention.

Figure 1 shows a front elevation of the locking jaw, partly in section, Fig. 2 the corresponding plan,'Fig. 3a section through Fig. 1 on line A-A, and Fig. 4 a section through Fig. 1 on line B-B. Figs. 5-11 show a device on the locking device for the line, intended, when 'a line is not fully set, to prevent the foremost matrix from turning during the transfer of the matrix line to the elevator and from causing disturbances, namely Figs. 5- and 6 show one construction in elevation and plan, while Fig. 7 is an elevation of a second construction. Figs. 8 and 9 show a device in which the springy jaw can be locked in its back posit-ion by hand, in case the casting of the line is to be repeated. Fig. 8 being an elevation and Fig. 9 a plan. Figs. 10-11 show an- -other construction by which the spring member is automatically operated or locked, Fig. 10 showing the position after the introduction of the line between the locking jaws, and Fig. 11 shortly before the introduction of the line in case of multiple casting.

For locking the line set, for the purpose of carrying it farther to the casting devite, is used, as is well known, a device in which the line consisting of matrices and spacers, is gripped between two jaws which must be arranged in an adjustable manner for the purpose on the one hand of enabling the length of the line to be altered, and on the other hand, for allowing, during the justifying, a small widening in order to insure better driving in of the spacer Wedges.

- It is already known to arrange one and the same means for these two adjustments, namely a screw secured to the frame of the machine, while in the adjustable jaw is mounted the corresponding nut. That device has, however, the disadvantage that in adjusting the line, it is necessary to disconnect the screw from the justifying mechanism which disconnection is a complicated matter. It has been attempted to remedythe disadvantage by inserting between the nut arranged in the jaw, and the jaw itself, an adjustable connection which was used for setting the different lengths of line, and by leaving to the screw spindle only the adjustment for the purpose .of justifying. lhis arrangement occupies, however, too much space, and also increases the number of adjustable parts on the mach-inc.

The locking device according to this invention (Figs. 1-4) is a device which goes back to the joint operation of the two'adjustments by means of one part, but on the other hand affords means for avoiding the above mentioned difliculties combined therewith. The spindle 19 used for the adjustment is mounted with its front end 20 in the adjustable jaw in a rotatable but not longitudinally movable manner. The adjustablejaw is shown in the drawing consisting of two parts, 21 and 22, the latter one of which rests against a stop arranged in the former. This division of the locking jaw has nothing to do withthe invention itself, but has been made only for the purpose of enabling the vise jaw to be moved entirely,

to the right when there are no matrices in the line, and only reg-lets are cast. In the frame of the machine 23 is mounted the nut belonging to the spindle and consisting of two part 24 and 25. Between the two parts of the nut engages the front end of the spindle 26 flattened on both sides and thus forming a cutting edge, which can be rotat-ed by means of a handle 27. By rotating the spindle in question, the two parts 24 and 25 of the nut are moved outward away from the spindle 19, so that they release the latter, and the spindle becomes longitudinally adjustable. The springs 28, after the turning back of the handle 27, bring the nut again into engagement with the spindle. The spindle itself is preferably provided with a division in accordance with ty e bod d3- mensions, preferably with a pitc of cicero.

The spindle is provided with a slot 29 extending throughout the whole of its length and engaging with a key 30 connecting the spindle to the bush 31. The spindle is consequent-1y adjustable but not rotatable relatively to the bush 31. The bush 31 is mounted in a slotted crank 32 composing opposed movable clamping jaws 36 and 37 which can be fixed lay-tightening a set-screw 33. The crank 32 is operated in the well known manner by means of the rod 34 and the spring 35, from the justifying mechanism.

The working of the device is as follows: Before or after the justifying, the crank 32 effects in well known manner a reciprocation and being secured to the bush 31, rotates withthe latter the spindle 19 to and fro.

The spindle, and with it the locking jaw, is

consequently slightly moved to and fro as the nut is in engagement with the spindle. If it is necessary to adjust for another length of line, this is effected-when it is a question. of an adjustment, as is generally the case, to the extent of complete or cicero unitsby turning the. handle 27, whereby the two parts of the nut are moved away from each other, whereupon the spindle is moved to the right or to the left to the extent of a corresponding number of threads. Only when it is necessary to adjust to the extent of smaller units than 3 cicero, it is necessar to release the setting screw 33 and to e ect the adjustment by manually turning the spindle. The bush 31 participates in the rotation of the spindle, and is afterward fixed again in the crank 32 by tightening the set screw 33. When the line is not set completely full, there is between the matrix at the farthest left hand end, and the adjustable locking jaw such a great clearance that the matrix in question can easily turn and cause trouble. In order to remedy the'drawback in question, a spring member can be pushed in, which always comes 'to lie close against the left hand matrix and prevents it from turning over.

In the construction shown in Figs. 5-7, the adjustable jaw 22 whichrests in well known manner against the stop 29, is slotted in the center. Into the said slot is introduced an adjustable part 312 pressed forward by a spring 313, the movement of the part being limited by a pin 314. In the pushed in position, the insertion 312 is flush in front with the adjustable j aw. Before the line arrives, the part 312 is in the position shown dotted in Figs. 57. The matrix line 315 'is then moved in well known manner between the two grippers to the casting point, and the left hand gripper 316 strikes during that movement with its point a projection or stop 317 of the part 312 and pushes the latter in as far as required by the length of the line just set. lVhen the matrix line is carried downward between the jaws, it

will always rest on the left hand side close against the part 312, so that a turning of the first matrices is prevented. During the subsequent justifying of the line, the spring 313 which is only a weak one, is compressed to such an extent that. the front edge of the part 312 is flush with the front edge of the jaw. The part 312 in the position of rest projects from the jaw to such anextent that it remains operative even in case of the loosest line. The arrangement in Fig. 7 is very similar, only in this. case the whole jaw 22 is mounted in an adjustable manner. In order to insure greater mobility, it can be preferably mounted on rollers or balls 318. The movement forward toward the matrix line is effected by the spring 319, and the stop 320 prevents the jaw from being moved too far toward the matrix line.

In making repeated castings, the construction shown in Figs. 5-7 would have the disadvantage that when the line in the casting carriage from its uppermost position is brought for the second time between the locking jaws, it would come to rest on the upper edge of the part of the locking jaw, advanced by the spring, as the finger which otherwise adjusts the spring member to the proper width, is no longer present in this case, but has been already moved back to its original position for receiving a new line. Below are given two methods for remedying the disadvantage in question and for locking the spring jaw part in its rear position.

In the first construction shown in Figs. 8 and 9, the locking jaw 22 is itself exactly the same as in the construction shown in Figs. 5 and 6. In this case as well, the CeI1-' tr'al part 312 is adjustable and is pushed forward by the spring 313, a pin 314 being provided for limiting the travel, and guided in an elongated hole in the stationary part of the jaw. There is here further provided a spring 336 with a button 334 for seizing it, and-with a locking toot-h 335 on the bottom surface. If the movable or adjustable part 312 is moved in the usual manner by the matrix line, that is to say, to such an extent that its front surface is flush with the front surface of the two lateral stationary parts, the locking tooth does not act as it does not yet come into engagement, on the contrary, the part 312 again springs forward after the removal of the line. If. however, the line is to be cast repeatedly. the compositor presses the part 312 somewhat farther intothe slot between the two lateral parts. In that case, the'locking tooth 335 springs behind the part 314 as shown in Fig. 8, and thus locks the part 312 in its back position. The matrix line 315 can then be brought into its bottom position without the part 312 disturbing and coming into its path. When this line isdistributed and a new line set, the compositor, by raising the button 334, releases again the spring device, and the setting is continued in the ordinary manner.

In the construction shown in Figs. 10 and 1.1, hand locking becomes superfluous, nevertheless the path for the line always remains free, as the spring member is pressed against the matrix line only when the latter is already between the locking jaws. In the position of rest, the locking jaw 22 is in the position shown in Fig. 11. The spring member 312 is carried by a bolt 337 provided at its end with a collar or with a nut 338. A spring 339 which on one side rests against the jaw, and on the other side against the collar draws the spring part 312 111 the position of rest into the jaw always to such an extent that its front surface is flush with the front surface of the jaw, that is to say, does not reject into the path of the matrix line. Beliind the bolt 337, in the same recess, is arranged a spring 340 which is stronger than the spring 339, andthe other side of the spring 340 rests against a bolt 341 prevented from turning by a pin 342 guided in a slot of the locking jaw 22, which pin limits at the same time the travel of the bolt in question. The rear end of the bolt 341 is beveled. The first elevator or casting carriage 343 which receives the matrix line from the collector and carries it to the casting or distributing place, is provided with a projection 344 with a bevel corresponding to the bevel of the bolt 341. When the casting carriage is lowered in order to bring the matrices into the casting position, the projection 344 engages with the bolt 341 and forces the latter into the position shown in Fig. 10 into the locking jaw. The spring part 312is then moved into the path of the matrix line, the spring 339 being at the same time compressed, namely at the moment when the matrix line is already partly between the locking jaws. T he spring part. engages then with the matrices standing on the farthest left hand end, the spring 340 being compressed to a greater or less extent according to the width of the matrix line. The justifying then takes place, and the spring part is again the longer jaw owing to the widening of the matrix line. When the matrix line is moved after the casting into the distributing position, the spring part remains in the locking jaw owing to the removing of the stop 344 from the bolt 341, and at a repeated descent of the casting carriage. for the purpose of a new casting, the line, without finding any obstacle. can enter between the two locking jaws. In Fig. 10 is further shown dotted the line coming from the collector elevator, and subsequently received by the casting carriage. The locking jaw 22 is provided at" its back end with an oblique slot with forced completely into.

'gagement from the spindle,

which engages the projection or stop 344, so that the slide of the locking jaw facing the casting mold, retains its solid surface so that it could cover completely the casting slot if necessary.
