in a position to bring about the change at. any time by one simple inovement of a lever while composing.

The invention is particularly applicable to line-casting machines of the linotype system, as for example described in the United States patent specifications 436,531, 436,532

and 557,000. In these machines the moldwheel is enerally rotated a quarter-revolution between the ejection of one line and the casting of the next, the utilized mold being brought into the casting position from the ejection position. After a line has been cast,

the mold-wheel is rotated three-quarters of a revolution more, whereby the mold and the cast line are brought into the ejection position, in order to deliver the line into the line assembling galley.

Now according to this invention, instead of the mold-wheel rotating the standard quarter-revolution it is rotated a different amount, when another mold is to be used instead of that used previously. This modified rotation of the mold-wheel may be a quarter-revolution in the opposite direction. It will be readily understood that, in this event, instead of the utilized mold located in the ejection position another one, which is diametrically opposite to the previouslyused mold, arrives into the casting position. The invention may, however, be modified by a half-revolution or any other fraction of a whole revolution of the moldwheel taking lution backward before. a

this case itis necessary for changing the mold that the wheel rotate a quarter-revm -line is cast, in order to bring the other mold into the casting position, instead of that mold opposite to it, which has been previously utilized and which would be brought into the casting position a quarter-revolution forward. Foranoving the mold-wheel backward its' drlving mechanism must be reversed by the main shaft with the aid of reversing gear. The reversal must be done away with after the first quarter-revolution of the wheel, while this is stationary for the purpose of -casting,.in order that the following threequarter revolution may take place in the customary direction, 0. forward, and that the mold just utilized carrying the cast line may arrive into the ejection position and into the casting position again before the nextcasting operation. A fresh. reversal of the reversing gear causes a second change of mold to take place. Thus repeated reversal brings about as frequent a change of mold.

I The devices serving for reversing the direction of rotation of the mold-wheel must be constructed having regard to various points. For example, the composer can utilize capital letters of large font when he has to set a line serving as title. In this event he will change the font at the beginning of the line. In another case, when one single word to be emphasized occurs in a line, the comooser will only learn of the necessity of cianging the mold when he begins to set up this word and will then, make the change. IVhen he returns to the ordinary type after ending such a word, the change which has been prepared may not be negatived. Further, the peculiarities of the casting apparatus in the machine have tobe'taken into consideration. \Vhen the composer begins a line, the previous line will be, as a'rule, in the casting apparatus and the latter is in operation, and during this timethe driving gear of the mold-wheel may not be reversed. Again, the composer may have finished setting a line of matrices before the casting apparatus has delivered the cast of the previous line; if the composer now begins a new line with a change of mold, this change may only bc'inade. when the previous line has been completely cast.

-all the cams serving for controlling the casting apparatus. W'ith the bevel wheel 12 is connected a rectangular member 17 (Figs. 3 and 6) which lies against the side face of the wheel 15 and brings about and maintains the'exact adjustment of the gear wheels 12, 10, +1 and 9 and the mold-wheel 1. In the normal position of the main shaft the first tooth of the segment 13 meshes with the wheel 12 and as soon as the casting apparatus begins to operate drives the wheels 12 and 10 half a revolution. This movement causes the pinion 9, shaft 8 and wheel 4 to rotate one complete revolution and the mold-wheel 1 a quarter-revolution, the latter in the direction of the arrow 6 in Fig. 7.

In the new mechanism two gear wheels v 10 and 18 are on the shaft 11 carrying the bevel wheel 12 and two corresponding pinions 9 and 19 are provided on the shaft 8.

As in the known arrangement the gears 10 and 9 are in direct engagement, but the gears 18 and 19, on the contrary, are connected with one another by an intermediate wheel 20. The latter imparts the rotation of the toothed wheel 18 to the pinion 19, so that this rotates simultaneously with, but ina direction opposite to, the pinion 9. The latter is not firmly connected with the shaft 8 as in the known arrangenenubut by a detachable clutch, as clearly shown in Fig. 6. The pinion 19 is connected in like manner by a clutch with the, shaft end, the two pinions 9 and 19 have incisions 23 and 21, respectively, in their hubs 21' and 22, respectively. Driving pins 25 and 26, secured in the rod 27, can be introduced into these incisions by means of a rod 27 movable longitudinally in the hollow shaft 8? The distance between the pins and 26 is so much greater than the distance between the hubs 21 and 22 that the pins can only engage alternately in the hubs of the wheels.

Behind the pin 26 is a ring 30 loose on the shaft 8 and a powerful spring 31 which acts on the pins 25 and 26 and the rod 27. The spring abuts against a ring 32 secured on the shaft 8 and tends to place the pin 26 into the slot 2403f the hub 22 and simultaneously to remove the pin 25 out of the slot 23 in the hub 21. The pinions 9 and 19 are prevented from moving longitudinally alongthe shaft 8. The rod 27 projects beyond the end of the shaft 8 and has here a spherical face 35 which lies in a spherical face 3 of a lever 37, as clearly shown in Fig. 5. This lever is rigidly connected with an axle 38 and thereby with the lever 39 secured 611' the same axle. The lever 39 has To this i a roller 40 at its to end and an extension 11. This abuts agamst'the arm 13 (Figs. 3 and 5) of an angle lever which can rock around the pivot 4e and has an arm extending vertically upward. A draw rod 46 is pivoted at 17 to the arm i5 and at 18 to a two-armed lever 49, 50. This lever is fulcrumed on the pivot 51 and can reciprocate with thispivot secured in a lever 52 which rotates with the shaft 53 and the arm 54. The bottom end of the lever is located above the rear end of the shaft 56 carrying at its front end the lever 76 (Figs. 1 and 3) which serves for throwing into gear the casting apparatus and for controlling the line-transferring*earriage 77, it being connected with the latter by a rod 76*. WVhen the assembling elevator E of the machine rises the line-transferring carriage 77 is liberated inknown manner fromacatch 80 and then moves under the influence of a spring 78, which is attached to the lever arm 7 9 secured on the shaft 56, with the set line'to the first elevator H (Fig. l). The lever arm 57 carrying the roller 58 participates in the'rotation of the shaft 56 which takes place. The roller finally arrives in its extreme position against a clickpwherebythe latter is released and. causes the main clutch of the casting apparatus to be engaged. This and the other occurrences in the casting apparatus are not material for the mechanism which is to be described.

On the bushing 59, by means of which the lever 57 is secured on the shaft 56, is a pro-- jection or lug 60 which is located approxi-" m'ately vertically under the bottom end of the lever 50. -The position of the lug is selected such thatvthe line connecting its front face with'the center of the shaft in the normal position forms approximately an eng n of 45 with the vertical and that itappro'ximately coincides with the vertical wheathrhaft 56 has rotated out of its normal position into its extreme position f r'actuatin'g the driving clutch of the machine. It wil beg'readily understood that the pointpf the l ilgmoves, during this rotation, along an arc and that this movementca'n e resolved into a norizontal and a vertical component. The two components of the movement are utilized in various ways in the apparatus.

As long as no change of mold is to take placethe bottom end of the lever 50 is at such an elevation that the lug 60 does not contact with the lever arm 50 during a rotation of the shaft 56. This elevation is maintained by a locking device which coacts with the lever arm 54, and the arm 52 and the lever 49, 50 are thereby prevented from descending. This locking device com.- prises a locking lever 62 fulcrumed on the axle 63 and pivotally connected to a rod 65. This connecting-rod 65' is connected by the cation the roller 69 is pressed downward by the projection 72 of the se ment 71. Each reciprocation of the ban le 73 causes a change of mold, the described apparatus working as follows: When the roller '69 is pressed downward the rod and the looking lever 62 are lifted. The latter slides off the end of the arm 54 and releases the same. Owing to the weight of the lever 49, 50 the arm 52 carrying this lever rocks around the shaft 53 and drives the arm 54. When the roller 69 has passed the projection 72 on segment 71. it returns into its normal position, the'locking lever 62 remaining on the broad end of the arm 54. The rod 65, being guided by the pivot 64 in an oval slot and thereby independently of the looking lever 62 falls immediately back into its bottom position and by its excess weight presses the roller 69 againstthe segment 71 thus preventing an accidental movement of the latter. When the arm 54 is released, the lever 49, 50 moves downwardly longitudinally and its bottom end arrives in front of the lug 60. During the subsequent movement of the. line-transferring carriage, namely when a line is next conveyed from the setting to the casting position, the lug drives the bottom end of the lever 49, '50 and moves this laterally from left to right and, in addition, the entire lever 49, 50 upward. Owing to the latter movement, which is due to lug 60, the lever arms 52 and 54 are returned into their normal positions; the locking lever 62 again falls in front of the lever arm 54 and holds the same until it is released afresh, and the bottom end of the lever 49, 50 is out of reach of thelug 60 as soon as this has returned into its normal position. Simultaneously with the upward movement, however, a lateral movement of the lever arm 50 occurs, the same rocking around the pivot 51. This lateral movement is transmitted in the opposite direction by the arm 49 and the draw-rod 46 to the angle lever 43,45 rocking around the pivot 44. In

consequence of this movement the arm 43 releases the extension 41 of the lever arm 39, and the lever 37 connected with the latter now moves under the action of the rod 27 in .the shaft 8 and the spring 31 influencing arrive by means of a three-quarter revolution in the direction of the arrow 6 into the ejection position after the cast is finished. To this end, the rod 27 having the two driving pins 25 and 26 mustbe returned into its original position directly after the completion of the first uarter-revolution of the mold wheel. This is brought about by means ofa cam 75 which is provided on the .main shaft 16 and coacts with the roller 40 on the lever arm 39. While the mold-wheel itself is at rest on account of the casting, the main shaft 16 rotates and the cam 75 returns the roller 40, the levers 39 and 37 and the pins 25, 26 into their original, normal positions. The driving gear of the moldwheel is thereby reversed afresh so that the wheel rotates again in theordinary direction. At the beginning of the subsequent casting operation the mold 3 is in the ejection position and owing to the ordinary rotation of the wheel 1 arrives into the casting position 5. The mold 3 remains in use until the mold 2 arrives again into the casting position 5 owing to a new temporary reversal of the rotation of the mold-wheel.

It follows from the above that the change of mold takes place, if occasioned by means of the handle 73, when the line in question is conveyed from the setting to the casting position. If a line be situated between the setting and casting positions, in the socalled waiting position the shaft56 and the lug 60 have turned so far that the bottom end of the lever 49, 50, when released in this moment does not fall in front of the lug 60 but onto the back thereof. Consequently, the end of the lever arm 50 is not driven when the transferring of said line is going on but remains in the disengaged position until the lug 60 returns into its normal position, which can only occur when the linetransferring carriage has delivered the line situated in the waiting position to the first or casting elevator.

The 'cam75 is formed in such manner that it only admits of the reversal of the driving device when the casting apparatus is located in the ejection position or in the rest position. In each intermediate position the cam 75 coacts with the roller 40 and thereby prevents reversal until ,the casting operation is finished. I

Mechanism for adjusting the line trimming blades has to be combined with the and is of varying height according in each instance to the width of the mold.

In Figs. 9 and 10 the mold is illustrated in cross-section in two different positions opposite the blades. Of the two blades or cutters 100 and 101 the former is stationary whereas the latter is arranged to rock around an axle 102.- This axle is journaled in an adjustable holder 103 secured by means of screws 104 to the body 106. The latter is connected by means of screwbol ts 107 with the frame 108 of the matrix-clamping device commonly called the vise. The holder 103 can be so adjusted by means of an attachment screw 109 and two adjustment screws 110 (Figs. 8 and 9) that the edge 111 of the blade 101 is parallel with the edge 112' of the blade'100. The blade 101 is not connected directly with the axle 102 but with a support or carrier 113 secured on the axle 102. On this support is an abutment or arm 11 1 which enters into the incision 96 in the mold soon as the mold is opposite the blades and is caused to approach the latter by the machine. Further, a body 115 having two arms 116 and 117 is journaled on the axle 102; these arms enter into the movable abutments or pins 118 and 119, respectively, which move in guiding bushes 120 and 121, respectively. These guides or bushes 120 and 121 are slotted at 122 (Fig. 9). Likewise, the pins 118 and 119 have slots into which the lever arms 116 and 117 respectively enter. Further, there are connected with .the body 115 which carries the lever arms 116 and 117 two additional lever arms 125 and 126, against which the ends of a leaf spring 127 press and thereby tend to rotate the bodv 115 carrying said arms so that the pins 118 and 11.9 are shifted forward as far as possible. Two

faces 131, one of which is provided on each of the arms 116 and 117 (Fig. 9) now drive the body carrying the blade 101 by means of the faces 129 provided on this body 0pposite to the faces 131 (l igs. 8, 9 and 10) so far that the edge 111 of the blade 101 is removed as far possible from the edge 112 of the blade 100. The arm rigidly connected or integral with .the'body 113 also participates in this rotation. If the moldwheel 1 carrying the mold 2 is now caused to approach the blades, which is brought about automatically by the machine before the ejection of the line in well-known manner, two stops or abutments 133, .Which are integral or rigidly connected with the mold, opposite to the pins 118 and 119, press on these pins and thereby rock the levers 116, 117,115 around the axle'102 against the action of the leaf spring 127. The spring 134 tends to impart the rotation of the body 115 to the body 113 and the blade 101, and the body 113 yields to this force until the lever 11 1 abuts against the face 98 of the mold 2. At this moment the correct distance between thsa-edges 111 and 112 of the blades is obtained. The further rotation of the body 115 only compresses the spring 134 thereby securing the position of the blade 101'. The ejector 135 now begins to push the cast line 136 out of the mold 2 and conveys it between the edges 111 and 112 into the galley 137 in front of the blades (Fig. 1). After the mold has receded the leaf spring 127 returns the body 115 having the arms 116 and 117 and the pins 118 and 119 into their normal positions.- The abutment faces 131 on the lever arms 1.16, 117 drive the body 113 and the blade 101 on the same by means of the faces 129.

The thickness of the line to be trimmed is determined by the distance between the edges of the blades 101 and 100. This distance depends on the position of the face 98, because this limits the movement of the blade 101 by means of the lever arm 11%. The face 98 is on the body forming the mold and can be so'made on each individual mold that, when the mold in question approaches the blades, the blade is positioned corresponding to the width of the mold. The blades can be adjusted exactly, without departing from the scope of the invention, solely by the stops or abutments 133 (Figs. 7, 9 and'10), in which event the stop 98 becomes superfiuous. This is without significance for the essence of the invention. Namely, according to the invention the blades 100 and 101 are adjusted for a definite line-body or width of mold by stops or abutments which are arranged on the mold itself and which cause the blades to be adjusted whenever the mold is changed. The special advantage of the stops 133 is that the spring 134 does not require the extensibility requisite for the entire movementof the blade carrier 113 and therefore can be selected very powerful in spite of the limited space, so that the movable blade 101 is held securely in its operative position. But it is necessary, however, that the stops or abutments 133 be approximately adapted to the width of the molds and bring about a rough adjustment of the bladeltll.

As follows from the above, the distance between-the blades isadjusted each time, corresponding to the width of the mold used and therefore changes automatically when a different mold is used. To change the mold and to make the requisite fresh adjustment of the blades 16?.111'88 only one single ma- 'nipulation, name y a movement of the lever manifold ways. The mold-wheels, for ex-- 73. The segment 71 on this lever, which operates the other members for adjusting the mold and blades, maybe connected with an existing handle, a; 9. one serving in machines havingseveral ma 'azines for changing the latter, so that-w en the magazine is changed a change of mold occurs automatically.

The above described illustrative embodiment of the invention ean'be modified in ample, may contain an optional number of like or different molds. Then when one of these molds arrives after use into the ej'cc tion position, every other-mold in the wheel can be brought into the casting position by a partial rotation of co'rres onding amount and direction. These artial rotations can be brought about rea ily by means of reversible toothed wheel gearing of suitable ratio of transmission. The arrangement of.

a largenumber of reversible gears is well known generally in machine constuction, g. in motor-cars. Also it is not necessary for the partial rotation serving forplacing a mold into the casting position to take place at the beginning of the entire casting operation. but otherwise it must take place between the ejection of one line and the casting of the next.
