panying'drawings, forming a part of the same.

Our invention relates to record controlled type casting and composing machines, and more particularly relates to improvements in the means whereby the usual operations thereof are modified so as not to cast characters ity is desired to omit from the composition. 7

Machines of this type have been illustrated in connection with the United States patent to G. A. Goodson dated August 16th, 1898, No. 609,098, and also in Patent No. 715,233, dated December 9th, 1902, issued to WV. Ackerman, co-inventor of the present improvement, it being'the purpose of the presentinvention toattain this end in a more direct and etfectualmanner.

I Vhile the preferredcform of our niacha-' nism illustrated herein is designed to operate in connection with a type casting machine, such as is described in our joint U. S. Patent 964,677, it is not desired to limit the application of the same to that one form of machine, as with unimportant modifications it may be adapted to operate in conjunction with other forms of type casting machines. Nor is it essential that any par ticular form of controller mechanism be employed to operate the, parts constituting our invention, and therefore the tape controller described in our joint United States Patent 964,678 which is adapted to operate in connection with the type caster of our first mentioned joint patent may be used, or the selector controller devices described in our joint Patent No. 964,679 may be employed with the sameresults, However, inasmuch as the present invention in its preferred form is applied to the type casting machine described in our last mentioned patoutin this connection that in the use of the perforated tape controller of the type def scribed in connection without first mentioned patent, a slightly. different order is followed in its preparation and presentation to the type casting mechanism than insetting the separable'controller devicesfor selectors of theso-called one man machine described in our said joint Patent 964,679.

We will therefore briefly refer to the perti-,

nent features of the two methods, in so far as they relate to our present apparatus.

Thus, in preparing the tape the operator wi]l by means of the proper key make a special line cancel perforation in the strip in thespace immediately following matter to be omitted, in the place of the usual justification perforation, which is immediately followed by the trip signaling perforation. YVhen the ribbon is fed through the index headin its reverse order, as is usual in machines employing the tape record presentation, the trip perforation through the electrical contacts may thereby oause'the cam that constitutes the justifier partsto rotate, which as one of its functions will be made to actuate the mechanism of our present invention which by operating special means presently to be explained, is adapted to render inoperative the mold plunger actuating means,rnot only during the setting of the justifier parts, which is normally and automatically performed each timethe usual trip signal controller passes through the index head, but also for the extended period covering the line cancel requirements, which is efliectedthrough' the action of the special line-cancelin erforation of the tape above'referred to. Such mechanism is necessary for the reason that the mold plunger mechanism being actuated by the main driving shaft would cast a type at each revolu-f tion thereof, unless some means is especially intervals.

provided to prevent its operating at certain Furthermore, inasmuch as the driving shaft of the caster is carried through two rotations while the jiistifier cam is operating to set the justifier mechanism and perform the other functions relating thereto, it is obviously indispensable that the justifier cam should interpose preventive means to the action of the plunger mechanism while said cam is performing the operation above referred to. Therefore, as the trip perforation operates to cause the justifier cam to rotate, which in the manner indicated shuts on the pump mechanism from operating, it is only necessary to interpose an independently operated locking device to the mechanism thus ordinarily actuated by the justifier cam, which will retain the mold plunger in its in operative position indefinitely, or until the dead matter of the controller has been run through the index head of the machine. This separate mechanism is made necessary for the reason that the justifier cam only holds the plunger mechanism out of commission during a certain portion of its revolution, which plunger mechanismwould therefore be free to operate to cast type immediately upon the justifier cam coming to its normal position of rest.

Therefore, having interposed such independent locking device which may be termed the line-cancel latch mechanism, it is only necessary to construct such line canceling lock in amanner that will admit of its automatic release upon the succeeding revolution of the j'ustifier cam which will necessarily be tripped at the commencement of the next succeeding line to be reproduced in type. That is to say, inasmuch as each line of composition must preceded by a trip perforation, it is apparent that the line canceling lock will not need t6 be released until the new line is thus introduced into the composition, which is accomplished automatically by the action of the cam upon the latch mechan1sm. I

The controller devices employed in connection with the mechanism illustrated in our said Patent 964,67 9, may be employed to cocperate' with the mechanism of our present invention, and are introduced into the index head of the casting machine, in the same general manner in which the tape perforations are employed as above described. It is therefore not necessary to describe in detail in this connection the method whereby the justifier selector is introduced into the procession of selectors at theposition next following the trip selector at the head of those representing a given line, it bein apparent that the trip selector in the practice of our present invention will be followed im mediately by a line cancel selector which will have its selective collar located by the mechanism described in said patent at a position features an electromagnet which is energized to operate the actuating mechanism that controls the line, canceling locking device, which in the preferred form of our present invention comprises as one of its essential by action of a circuit closing device corresponding with the line cancel perforation or selector as the case may be.

Therefore, generically our in'iprovemen't includes in its complete form means for setting a controller device to operate a specially provided eiectromagnet which in turn will interpose a stop or latch mechanism in the path of the slide which operates the mold plunger, thereby preventing the casting of the type until such latching is subsequently released. It will therefore be necessary in describing our invention in detail to include certain portions of the mechanism described in the above patents, which incidentally are incorporated in the mechanism of our invention, it being apparent, however, that several equivalent mechanisms can be used for the same purposes. 7

Where our invention is employed in connection with tape operated machines, or those of the one man type in which separable controller selectors constitute the presentation record, the trip signal device in whichever form employed will be followed immediately by a specially prepared signal device which will operate the line canceling mechanism of our invention, thus occupying the position normally assigned to the justification perforation or selector as the case may be. 7

Heretofore, in connection with casting and composing machines, especially the electrically controlled class thereof, it has been the practice to have an electrically operated mechanism to engage the connecting rod which causes the pump plunger to operate to cast atype at each rotation of the cam driving shaft, so as to throw that member out of engagement with its respective actuating 110 cam, thereby rendering the pump plunger inoperative during the rotation of the justifier cam while that member is scttin the justifier mechanism, at which time 0 course no type will be cast. In our present invention 115 we have devised mechanism whereby the j ustifier cam drum, by action of specially designed cam surfaces thereon, will automatically interpose a locking arrangement in the path of the pump rod so as to hold that 120 member out of alinement with the pump operating cam on the main shaft of the casting machine, during the entire rotation of the justifier drum.

Hence, our invention broadly described 125 attains the object of the line cancellation by adding a mechanism whereby the locking device which is operated by a cam on the justifier drum to scotch the pump rod, may be held out of action indefinitely or until it 130 canceling look.

In the accompanying drawings, illustrative of a preferred embodiment of our improvement, Figure 1 is a plan view of a part of a casting mechanism showing a portion:

of the driving shaft of the type casting mechanism with the justifier cam and mold plunger rod. Fig. 2 is a sectional side elevation of parts shown in Fig. 1, showing the line canceling locking device in position to be thrown into engagement.

Referring to the drawings: 1 represents the frame of a type casting machine of the class to which our invention applies, having a bed plate 2, and a top plate 3 immediately above the bed'plate, and a main shaft 4 which is supported by means not shown, upon the framework of the machine. Upon the shaft 1 are the several actuating cams of the castin machine, only two of which are illustrate in the 'drawlngs in connection with our present invention, namely the'cam 8 which relates to the pump operating mechanism and the drum 15 upon which are the various cams employed in connection with the setting of the justifier parts, which will be referred to as the justifier cam, having added thereon a special cam 16 suitably arranged and timed to interpose a latch to lock the pump rod 5 from engagement with its cam 8. The justifier cam is loosely mounted upon a sleeve upon the cam shaft 4, which sleeve is a part of the mechanism by means of which the cam 15 is intermittently clutched to the cam shaft 4 through the action of a trip mechanism, fully described in connection with our said joint Patent No. 964:,697, it being sufficient to point out in this connection that whenever the trip is operated by means of which an operable connection is effected between the shaft 1 and the cam 15, whereupon the latter makes one revolution while the shaft is passing through two complete rotations.

Slidably mounted upon the top plate 3 is the pump rod 5 which is operably connected at one end with the pump plunger of the type casting machine and is carried by spring action in the direction of the cam 8 on the driving shaft, in order to operate said plunger to force the molten metal into the mold for casting type. Upon the opposite end of the slide 5 is a cam roll 7 which by the sprinoaction above referred to, is operably helcf in contact with the periphery of the cam 8, in which is a depression 9 into which the cam roll 7 is thereby thrust when that portion of the cam is carried into the proper position to operate the mold, the rearmost side of said cam depression being adapted by a gradual incline to return the slide 5 in its normal position with the roll upon the periphery thereof, as the cam 8 continues its rotation. In this manner the pump is worked by the spring actuated pump rod 5 to cast a type with each rotation of the driving shaft, unless held out of engagement with its cam by other means which it is the purpose of our invention to provide and will now be described.

A hook lever 10 that has heretofore been employed to act as a safety lock on the pump rod 5 is pivotally mounted upon a bracket extending upwardly from the top plate 3 and has its hooked end 11 adapted to engage corresponding toothed projection 6 upon the pump rod slide 5 while the roll 7 rests upon the periphery of the cam 8. The hooked lever 10 is therefore carried downwardly upon its-pivotal bearing in order to be thrown into a position to hold the slide 5 in the manner indicated, from dropping into the depression 9 for the purpose of cast' mg type.

The hooked lever 10 is held normally in looking position by spring yielding means 6, urging the hooked portion 11 into engagement with the toothed member 6 so that it requires releasing means in order to permit type to be cast. To this end the opposite end of the hooked lever 10 has an arm 12 which has a loosely pivoted finger 13 attached at the extreme end thereof and suitably held in a normally upright position by link connection with the frame of the machine so as to be contacted by the under side of the matrix frame A which is hinged to the top portion of the machine, and when type are to be cast thereby is brought down into position contacting the member 13 and lifting the latch 11 at the opposite end of the hooked lever 10; so that at the succeeding revolutions of the pump actuating cam 8, unless otherwise held out of engagement therewith, the roll of the pump rod will drop into the notch 9 of the pump cam and the plunger thereby operated to cast the type. Inasmuch, however, as it is necessary toief feet the line canceling omission in the castring operation of the machine while the matrix frameA is in position to cast, it is found desirable to throw the latch 11 into engagement with the tooth of the slide 5 while the matrix frame is in position to normally hold the latch 11 out of engagement therewith. Consequently the finger 13 is made in two parts yieldably connected one to the other by means of a compressionspring 14 supported upon a rod l4: so that as the matrix frame at A presses upon the top of the finger 13 it actuates the hooked lever 10 through yielding means to withdraw it from engagement with the tooth 6 so that the pump'rod may be carried by its spring to operate the pump when permitted so to do by the cam 8, asdescribed. 'Hence, while the hooked member is thus being held out of engagement with the slide 5 to permit the pump plunger to act, other means must be employed to depress the hooked end of the lever 10 into engagement with the tooth of the pump controlling slide 5 when it-is desired to pre vent the casting of the type while the-machine is in operable condition otherwise. Such result is. accomplished in the present invention by means of cam block 20, 11 the hooked lever 10 upon the top portion of which is the upwardly inclined cam surface 21, upon which bears a pin 23, projecting laterally from the swinging arm 22 that is suspended immediately above theblock 20. As the arm 22 is rocked to the right as shown in Fig. 2, the pin depresses thecam block, the surface 21 of which isthere shown in its normalnnlocked positiominvthe path of the pin 23. on said arm.

The arm 22 is pinned to a rock shaft 24 suitably supported in a bracket 2r upon the top plate 3 and is actuated by means of a lever arm 25 which issecured to said shaft 2 1 by means of the set screw 25. At the free end of the arm 25 is a stud 26 and loosely mounted thereon is a cam rollf27 which is held, by action of the torsion spring 28 on the rock shaft 24, in yielding contact against the periphery of a cam 16secured to the justifier cam drum 15. Thecam 16 is so designedthat when the roll ofthe, arm 25 is .restingupon the low portion thereof as bestshown in Fig. 2, the pin of the swinging arm 22 is carried out of engagement with the inclined portion of the cam surface 21 ofthe block on the latching. lever 10. having a raised portion thereon so designed that whenthe roll 27 rests thereon, the pin 23 will have been forced along the surface 21 withthe result that thelatohing lever .10 is thrown into engagement with the tooth projection ,6 of the pump slide, thereby locking it so asto forestall the castingoperation. The high part of the cam 16 is sufliciently prolonged so that it is .in contact with the cam roll to lock the pump throughout the major part of the rotation of the justifier cam covering all the setting operations thereof, during which period the pump is locked in the manner indicated. The cam however coming to its normalposition of rest as shown in Fig. 1, with the swinging arm 22 brought into the low part of the cam surface of the block 20, permits the latch 11 to be carried out of locking engagement with the pump plunger mechanism. Thus is attained the purpose of omitting the casting operations during the circuit setting process when no type are to be cast, it being necessary so to lock the pump mechanism for the reason that the main. driving shaft has rotated twice during. the revolution of the justifiercam, and but for theaction of the locking-mechanism at each revolution a type would have-been cast, whichwould of course not beperniissible.

\Vhile the mechanism .as thus far explaincd would be adequateflin forestalling the casting operations during the .period occu pied by the settingof the justifier-inechanism, it will be apparent that if the period of eliminating. type casting should be required to extend beyond the mere setting operation other-mecl-ianism will be required. Therefore, when a number of characters or an entire line is desired not to'be cast, z'-.e.,.to be-canceled, instead of inserting a justificationCQlltroller signal immediately after the trip signal in the usualway, a SPQClZLlfllllE cancel selector 0r=perforation is introduced at thatpo'int in the controller, which in our present form of mechanism when introduced into the index head, is designed to close an electric circuit in which is included an electromagnet 35which is provided with means forholding theswinging arm 22indefinitely in alocking position with referenceto the cam block 200 1 the hook lever 11.

The means byv which theimagnet 35. accomplishes this locking purpose comprises a lever armature -36 pivotally supported upon a post 37 being heldnormally outof contact with the magnet 35 by means of the spiral spring 38 secured to one side of the lever 36 at one end, secured at the opposite end to a pin suitably projecting from the post 3'7. llhe armature lever at its opposite end is adapted vto engage the bottom of a latch 40 whichis slidably mounted in a suitable bearing vertically disposedlin the bedplate 3, upon the upper end of which is the toothed portion 11 adapted to engage acorrespondingly hooked end 46 of a horizontal latch member 45 which is also slidably mounted in a bracket block 47 and adapted to slide in a path immediately above the position of the locking slide &0, and when the latter is held in its normal inoperative position shown in Fig. 1, to pass freely overthe head thereof. The vertically sliding latch member 40 is held in its normally disengaging position by means of a coil spring 1-2 upon the stem thereof, there beingprovided for the purpose a collar 43 suitably secured to the end thereof, the other end of the spring bearing, against the under side :of the plate 3 in which the slide 10 has its hearing. The horizontal sliding latch -member 45 .is connected by a short pitman 48 which is pivotally mounted with the latch member 45 at one end being at tached at its other end to the stud 26 upon the actuating arm 25 by means of which the hooked arm 11 is operated.

Gonsequently,.as the cam 16 rotates from the position shown in Fig. lit forces the arms 22 and 25 outwardly, therebyperforming two distinct functions, namely, pressing the hooked lever 11 into locking engagement with the pump rod, and at the same time carrying the horizontal sliding member 45 into a position so that if the magnet be energized the armature lever 36 will be carried against its spring 38 to force the ver tical latch slide 40 upwardly into engagement with the slide 45, so that as the cam 16 coming to its position of rest recedes from the roll the slide starts to return with it, but will now be held by the latch member 40 in the position to which the cam 30 has carried it in which position as has been seen, the cam of the hooked member, 11 is held to lock the pump rod. Thereupon the cam 30 remaining in the position in which it presents the low portion thereof to the slide 45, that member is only held by the latch 40, which is held in such position against the action of its spring 42. The armature lever having immediately returned to its normal position of rest, the parts will therefore remain in this locking position with reference to the pump rod until the justifier cam through the action of a new trip selector signal is caused to make another revolution at which time the cam 16 as its high part strikes the roll will move the horizontal latch slide 45 just enough to release the vertical latch 40 which by action of its spring will be carried out of engagementtherewith to allow the arm to fall back as the cam 16 rotates, thereby throw-' gized by a new line canceling impulse from a new line cancel selector signal, and the machine will resume its ordinary operation. Hence, the justifier cam 15 by action of the cam 16 therewith not only forestalls the action of the pump rod during the circuit setting operation, but also during the action of the working circuits for an indefinite number of rotations of the driving shaft or until such time as it is desired to start in with a new line of composition.
