SPECIFICATION formingpart of Letters Patent No. 715,233, dated December 1902- Application filed October 6, 1 902.

$ at whom it may concern:

Be it known that 1', WILLIAM AOKERMAN,

a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Omitting Means for Automatic Type Casting and Composing Ma the following is a specifica-.

chines, of which tion.

Machines which automatically cast, compose, and justify individual type according to the location of perforations in a strip of paper of the class set forth in United States patent to G. A. Goodson, dated August 16, 1898, No. 609,098, have means whereby a line will be omitted if the operator that perforated the strip discovered a mistake or fault and at the end of the incorrect portion'made the necessary perforation to set the omitting means into operation. Whenever the operator at the perforating type-Writer thatis used to make strips for these machines detects an error or desires to eliminate or substitute a new Word or ex-' pression to the composition, a key is struck which makes a perforation in the strip in the space which would otherwise have been occupied by justification-perforations. The tripkey is then struck, as usual, to produce the perforation which causes the tripping of the cam-clutch. The strip is fed to the castingmachine in the reverse order of its making in the perforating-machine. Hence when the part of the strip containing the undesired matter is reached the trip-perforation comes into action and throws the idle cam into'oporation, and then at the next feedthe cancel ing-perforation comes into action and causes the setting of the omitting means. In United States patent to G. A. Goodsom'dated'April 24, 1900, No. 648,201, means are set forth for opening the electrical circuit that passes through the trip that controls the action of the pump that forces the fluid metal from the melting-pot to the mold and matrix, which means 5 are set to operate by the proper perforation in the strip. These means, however, also open the working circuit, as the various i branches of the working-circuit have a comration, so as to trip a Serial No. 126,113. (No model.)

is to provide canceled line is being fed through the ma- I chine. I g 7 My object is attained by causing one of the circuits that are put in operative condition when the justifying-switch is closed to he closed by the operation of a canceling-perfomechanism which Will shunt the working circuit around the coils of the pump-trip magnet and render that magnetinop'erative until the justifying-switch is 7 again closed for justifying a correct line.

The accompanying drawings'show the mechanisms by which my object is attained and oniyso-much of the mechanisms of the prior Goodson machines as is necessary-to show the connections.

Figure l is a froutelevation of the common switch that is thrown when a trip-perforation appears to ciose the circuits used to efiect the justification of a line composed and cast on a machine of this nature with my improved omitting mechanism represented in'connection therewith- Fig. 2 is a front elevation,on larger scale, of the omitting mechanism with parts removed in order to show the construction. Fig. 3 is a side elevation of the omitting mechanism. Fig. 4 is a plan looking down from the plane of the broken line a: as of Fig. 2. Fig. 5 is a diagrammatic view illustrating the electrical connections of a machine of this nature provided with my improved omitting mechanism.

The angle-lever 1 has the upper end of its arm 2 held against a cam'3 by a spiral spring 4:. The cam is set in operation by the usual .is fastened to the clutch and clutch-trip mechanism provided for these machines. The end of the arm 5 of the angle-lever is connected with a rocking lever 6, that has one end connected with a vertically-movable slide 7, bearing insulated electrical contact-forks 8, and the other end connected with a vertically-movable slide 9, that bears insulated electrical contact-forks 10. When the angle-lever is engaged with the low section of the cam, the spring causes the levers to lower the slide 9 and lift the slide 7, so that the contact-forks 10 will enter the mercury-cups in the block 11 and close the circuits connected with these cups, which circuits are known as the justifying-circuits, and so that the contact-forks S will rise from the mercury-cups in the block 12 and open the circuits connected with these cups, which circuits are known as the working circuits. When the angle-lever is engaged with the high part of the cam, the slide 9 is drawn up, so that the justification-circuits are opened, andthe slide 7 is pushed down, so that the Working circuits are closed. With the switch in the position illustrated by Fig. 1 the working circuits are open and the justifying-circuits are closed. If justifyingperforations follow the trip-perforation which causes this switch to be set as illustrated, the justifying mechanism 'will be set for a line of characters, which will then be cast and composed. If, instead of justifying-perforations, an omitting-perforation appears in the strip, my omitting mechanism will be set in operation.

One end of an angle-lever 13 is connected with the switch-slide 9. The other end of this angle-lever by a link 14 is connected with a slide 15, that moves in a dovetail groove in a plate 16, that projects from the back 17, that frame of the machine. Mounted on and movable with the slide 15 is a pawl 18, with a hooked end 19. This pawl isnormally held forward by a spring 20. Fastened to the plate 16,which supports the slide, is a pawl 21, with a hooked end 22, that is normally pressed forward by a spring 23. A lever 24 is pivoted on a screw 25, that projects from the back 17. The lower end of this lever adjacent to the hooked ends of the pawls has three teeth 26 27 28. Extending in one direction from the lever 24 is an arm 29, car- I I cury-cups 31. 55

' hub of the lever rying contact-forks 30, adapted to enter mer- Extending in the opposite direction from the lever 24 is an arm 32, carrying contact-forks 33, adapted to enter mercury-cups 34. A spring is coiled on the 24 and has one end con nected with the arm 29 and the other end connected with the back of the frame, so as to throw the lever into such position that the pins 33 enter the mercury-cups 34 and close the circuitconnected therewith whenever the hooked retaining-pawls are disengaged from the teeth on the lower end of the lever. A pair of magnets 36 are mounted in front of the lever 24.

The armature 37 of these magnets is fastened to the upper end of the lever 38 the lower end 39 of which armature-lever extends between the hooked pawls and the teeth on the lower end of the contact-lever. WVhen these magnets 36 are energized and the armature 37 is drawn downwardly, the end of the armaturelever will push the pawls against their retaining-springs and disengage the hooks from the teeth of the contact-lever, so that the spring 35 will throw the arms to their normal positions and causethe contact-forks 33 to close the circuit that is connected with the mercury-cups 34.

As illustrated byFig. 5, the circuit-wires 40 of machines of this nature which come from the index-pins which are operated by the perforated strip for opening and closing the diiferent circuits branch and lead to the mercury-cups 41 in the block 11 and to the mercury-cups 42 in the block 12. From the mercury-cups 43 in the block 12 the circuit-wires lead to the composing mechanisms, and from the mercury-cups 44 in the block 11 the circuit-wires lead to the justifying mechanisms. The cups 42 and 43 are adapted to be connected by the contact-forks 8,carried by the switchslide 7, and the cups 41 and 44 are adapted to be connected by the contact-forks 10, carried by the switch-slide 9, as previously described. These circuits are arranged in the common manner. All of the branches of the composing or working circuit are connected with a common return-wire 45, that leads to and is connected with the coils of the pumptrip magnet 46, which coils are connected by a return-wire 47 with the outlet binding-post 48. In carrying out my invention a shuntwire 49 is connected with the return-wire before that wire joins the pump-trip-magnet coils and with one of the mercury-cups 34, which are connected by the contact 33 when the lever 24 is released by the action of the omitting line-trip. The minus mercury-cup 34 is joined by the wire 50 with the outlet binding-post 48. When the cups 34 are connected by the contact-fork 33, the current that would usually flow through the coils of the pump-trip magnet and operate the pump-trip flows around the pump-trip magnets and out through the shunt-wire 49 and the mercurycups 34 to the outlet binding-post48 on account of the less resistance in the shunt-wire than through the pnmp-trip-magnet coils. By reason of this all of the circuits which are connected with the outlet remain closed and all the mechanisms are in operative conditionexcept the shunted pump-trip. The return-wire 51 from the omitting-trip magnet 36 is connected with the common return-wire 47, and the inlet-wire 52 of the omitting-trip magnet 36 is connected with one of the justification-circuits which has been selected to be-made active by the omitting-perforation in the strip. When an omitting-perforation appears in the strip after trip perforation IIu has closed the justifying-switch, the circuit illustrated by the wires 51 and 52 is closed. This energizes the omitting-trip magnet 36, which, through its armature, releases both of the pawls from the lever 2t and allows that lever to be thrown by its spring 35 so that the contact-fork 33 enters the mercury-cups 34 and closes the shunt-circuit 49 around the pump-trip. The first time that the justification-switch is closed if an omitting-perforation follows the magnet 36 is energized and allows theshunt-circuit to be closed. When the slide 9 is lifted by the action of the cam, so as to open the justification-circuits, the hookof the movable pawl 18 engages the tooth 27 and draws the lowerend of the lever one step against the pull of the spring 35. This does not, however, lift the arm 32 sufficiently to draw the contact-fork 33'out of the mercury-cups 34 and break the shunt-circuit. The fixed pawl holds the lever and the fork in these positions. The next time the justification-switch is closed and opened the pawl 18 is carried forward and the hook 19 engages the tooth 28 and draws the lever a further step. This draws the contact-fork 33 completely out of the mercury-cups 34 and opens the shunt-circuit.

Machines of this class have a mechanism which is set into action to open the main circuit by a circuit which is closed when a cast line is too short or too long. Of course when a line is omitted and no type are cast this mechanism would ordinarily act as if the line were too short. To prevent this, when a line is omitted the mercury-cups 31 are connected in the circuit 53 with the coils 54 of the magnet that operates the automatic cut-out, so that when the omitting mechanism is in operation by reason of the closing of the shuntcircuit by the fork on the lever 24 the automatic cut-out circuit will be opened by reason of the withdrawal of the fork 30 from the cups3l. Ifjustification-perforationsinstead of an omitting-perforation follow the tripperforation, the omitting-magnet is not energized, and the pawls retain the lever 24, with its contact-fork 33, out of the mercurycups 34 and its contact-fork 30 in the wells 31. By means of this simple arrangement the current is shunted around the pump-trip magnet without opening the circuit that actuates the composing mechanism. Then an omitting-perforation appears, all of the mechanisms except the pump operate as usual, causing the matrix to move around and to be stopped in exactly the same positions as if characters corresponding to those in the line which is to be omitted were to be formed; but those characters are not cast for the reason that the pump is not tripped so as to force metal from the melting-pot to the ma trix. As a result of this the machine'runs as noiseless as usual, and the wear of the parts is distributed. The matrix is not thrown to its extreme position each time and the centering-pin repeatedly forced into the same hole so as to beat out the metal of the matrixplate and cause it to spread into the matrices "adjacent to the corner where the spaces are formed, and thus obstruct the withdrawal of type cast in those matrices, as in the prior machines, when the working circuit is completely opened to cause a cessationof the casting. v
