this bar is connected to a jaw closing mechanism which operates to move the jaw I inwardly or toward the jaw 2 to lclose against a matrix line after the latter has been presented between the vise jaws and to move the jaw I outwardly against its stop after a cast has been made. The jaw closing mechanism shown in the present instance is similar to that shown and described in my prior application, Serial No. 612,349, filed May 19, 1932, it comprising an arm 6 which is pivotallj7 connected to the bar 5 by a link 1, this arm being pivoted at 8 on a stationary part 9 of the machine frame, the arm 6 being connected to an arm I0 which is operatively connected by a spring II to a lever I2, the latter being pivoted at I3 on a stationary part of the machine frame and having a forked rear end which straddles the usual cam shaft I5 on the machine, the arms of the fork of the lever I2 being provided with cam pieces i6 and I1 which are successively engageable by a roller or projection I8 on the cam shaft and operative respectively to close and open the jaw I at appropriate times in the cycle of operation of the machine, Vthe jaw I being closed against the line yieldably through the action of the spring II. The lines of matrices M which may be composed in the machinein the usual and well known manner, are received by the jaws I9 of a line transporter which may be the usual so-calledvilrst elevator as employed in machines of this class, the matrices in each line being supported in this elevator by the usual lugs or ears which project forwardly and rearwardly. from their upper corners and hang from rails on the jaws of the elevator in the usual and well known manner. '.Ihe line transported or first elevator lowers' the matrix lines between the :vise jaws and into a position in front of a mold 20 which may be of the form commonly employed in machines of this class, having a slot or cavity in which a type bar or slug is cast against the 'character bearing edges of the matrices presented thereto, by metal injected into the mold from the metal pot in the usual and well known Way.

` The matrices, as usual in machines of this class, may have upper and lower type forming characters or cavities m located at different heights or levels thereon, as shown in Figure 4, or head letter characters located thereon at the level of the lower character of such two-letter matrices, or the matrices may have relatively large or advertising display characters m formed thereon at another orrlowermost level, as shown in Figure 3, the molds used conforming withvthe kinds of matrices from which the casts are to be made and the line transporter or rst elevator being stopped in its descent so that it will present the matrix lines at 'the proper alining levels with respect to the mold. The means shown in the present instance for stopping the descent of the rst elevator at one or another level corresponding to the alining level at which the matrix lines should be positioned in front of the mold cornprises an alining bar 2I which is sldable longitudinally in the top of the vise cap 3, this bar carrying pins 22 and 23 which project upwardly therefrom to different heights, and one or the other of these pins or the top ofthe bar 2`I is engageable by an adjustable stop screw 24 which is fitted in the head 25 of the first elevator to stop the descent of the latter at the required height for alining different height characters on the matrices in front of Ythe t'ype bar or slug casting mold, the engagement of thev screw 24 diready with the upper side of the aiming bar :I serving to aline the upper characters on the matrices with the mold slot as shown in Figure 4, the engagement of the screw 24 with the pin 23 serving to aline large or advertising display characters with the mold slot as shown in Figure 3, and the engagement of the screw 24 with the pin 22 serving to aline the lower of the two-letter characters or head letter characters on the matrices with the mold slot, the level to which the first elevator and, in consequence, the matrix line is lowered in front of the mold being controlled by shifting the alining bar 2I longitudinally to bring one or the other ofthe pins 22 and 23 or the top surface of the bar 2l into position beneath the screw 24 on the first elevator.

In order to retain the vise jaw I against movement inwardly or against the matrix line until the line is lowered between the vise jaws, a latch 25 is provided, this latch in the present instance being pivoted at 21'to a bracket 28 which is xed to the top of the vise cap and may serve to support the stop screw 4 'for the jaw I. The latch 26 has a downwardly projecting portion 26 which is engageable in a notch 5 in the bar 5, the latch 26 normally resting by gravity with its downwardly extending portionZIiil engaged inthe notch 5a in the bar 5 and thereby 'retaining the jaw I connected to the bar 5 in its normal open or matrix line receiving position against the stop 4, and an upward swing of thev latch about its pivot 21 serving lto disengage the portion 2li'r1 from the notch 5a and thereby releasing the jaw I for inward movement against the matrix line.

According to the present invention, a latch releasing member or pawl 29 is pivoted at 30 to the latch 26 and has a toe 3I which projects into the path of one of the jaws I9 of the first elevator so that it will be depressed as the first elevator descends toA present a matrix line between the vise jaws and in front v.of the mold. A block 32 is fixed on the alining bar 2I by a screw 33 which preferably engages in an elongated slot 34 which enables the block 32 to be adjusted longitudinally of the alining bar 2l, and the block 32 is preferably provided with an indicator mark 35 and the top of the vise cap 3Y is provided with cooperating indicating marks with which the indicator mark 35 may register to indicate the different settings for the alining bar 2|, the indicator marks shown in the present instance on the vise cap being Normal, H. L. and High and designating and corresponding with the setting ofthe alining bar 2| to arrest the descent of the rst elevator respectively at the normal alinement level at which the stop screw 24V onthe first elevator directly engages the top of the alining bar, the intermediate orv head letter alinement level at which the screw 24 engages the lower alining pin 22, andthe high alinement level at which the stop screw 24 engages the higher alining pin 23 and thereby arrests the descent of the first elevator at the highest level as shown in Figures 1 and 3. The block 32 has a pivot or fulcrum pin 36 projecting therefrom and into a slot 31 formed in the releasing member or pawl 29, this pin being shiftable longitudinally in said slot when the alining bar 2I is shifted longitudinally `to set it in one or another of the positions described to control the extent of descent of the first elevator, the slot 31 being so shaped that the vpivot or fulcrum pin 36 will position the toe 3I on the releasing member 39 at such a height as to cause it to beengaged and actuated to release the latch when the elevator is within the'vsame l 'l'evel,H the pivot onfulcrum lscrew 35 will restiat "l co ofits iinal'stopping point.

ieetnssa distance .of ,its final i"stopping" point, whether the `alining: barl is set f or thehighestorlowest alineirnent levels ser for the intermediate .alinement level. For example, Figures 6 4and 7 showpthe .pivotxor fnloru-m pin 35 respectively atthe,-."oppo :siteends vof the slot''l'corraipcnding to :the `set-- tingacf the aliningl bar 2l .for normaler lowest :andthe Vhighest' alining positions respectively, and lit @will vbereen from these v'figures .thatv the 'nrst elevatorwillstrike and: depress ,the toe 3 l aofthe@ releasing ,member 25,: in each instance, when' .theiiirst Y'-ilevator yiswithin` the same distance When the alining bar'i isfset in an.intermediatefposition for the stopping ofy the yidrst elevatcruat the intermediate aninterinediate. pointin thelength-oifthe slot 3l, and the'toc 3l of the releasing member will then be set; at :jsuch'a height that it will be engaged and, depressed by the iirst... elevator when V4the latterY is v/ ithin the samedistance Vof its final intermediate stoppingpoint as indicated by the distanceXin Figures 6: and '7. Since the pivot lor fulcrum vpini is supported bylthe alining bar ata point betweenthe-toe V3i or the releasing member .2S and the pivotil which connects said to the' latch 2t, `depression of thetoe Si `byfthe descending first elevator willrock the portionita of the latchjnpwardly out of Vthe notch linthe bar` 5., thereby releasing this bar and the movablejawi connected thereto so that the latter mayclose against the matrix line,V and since `the pint. is carried bythe alining bar .2! so, that it is shiitable' therewiththe settingof the `releasing member 29 for the release of the jaw Al is controlled by or coordinated with the setting of the alining bar tov determine .the level to which theilrst .elevator` lowers the matrix lines be-` tween the vise jaws. 1' f n In operation, sliding of the alining bar" 2l' to bringthe indicator mark 35 into registerwith thermarlrzon the fvise Vjaw corresponding .to the Adesired setting ofthe alining bar positions the alining bar to stop the descent ofthe first elevator at-the desiredlevel andalso `shifts the pin 35 in the slot 3l of, the latch releasing memberl@ andv thereby automatically rocksv themember 29 to raise orlower its toe Si, according to the direction in which the alining Vbar `is moved, Figure 6 showing the"releasingmember all in its highest position corresponding to'y the position of the parts in "Figtlrej, l whercinthe high alinement pin 23 stands beneath the stop screw 2t conforming with the vsetting fof the indicator mark .35 in register with the High indicatorv mark onl thev will be engageable directly 'with the top, of the alining bar, the pin 3d being thenshifted to the. lefthand end of the slot Stein the latch releasing member 2g and the latter then occupying itsr lowest position. Setting ofthe alining bar, 2| in an intermediate position so that the Yindicator mark 55 thereon registers with the I-I. L. indicator mark on'th'e vise cap will bring the alining pin 22 into position Ybeneath the screw 24 to stop the descent of the first elevator at an intermediatelevel and this settingof the'alining bar 2i will concurrently set. the pin 36. at a point intermediately of the length lof the slot 3l in the latch releasing. member. 29' "and will thereby set this member-with its toet! at an .intermediate height. Thus, for eachsetting ofthe alining bar 2l;todeterminefthe-level to which the first elevator descends to present `the matrix-line'zbeitween theY visejaws, thetoe. 3iV ofl the latchrevleasingmember 29 -will be' positioned atv such ya -heightthat it'will always be struck by the first ,elevatcrwhen the latter is'thesame distance abcvepits. aliningstop; so that the jaw retaining latch Etiwi'll always be tripped to releasectheV jaw "l for inward"movementzunder the action of the closing mechanism when the matrixV line has `been brought down between; therjaws to the lowest peint possible/for any given alinement and hence premature releasing of. the vise jaw and consequent interference with the proper presentation .of the matrix lines between the vise vjaws and in front of the mold is avoided. l
