j 1s claim.

My invention relates to improvements in typecasting or type setting machines. It has for one object to provide in vconnection with such a machine wherein letter carrying'- members are 5 mounted for movement along lines other'than horizontal, means for automatically holding the type carrying members in place during a part of the operation. Y

Another object is to provide means in combil0 nation for-longitudinally displacing a' plurality of bars or matrix strips, arresting the movement f of each strip in a predetermined position, aligning the characters on or associated with or controlled by the various strips in register with a mold, squeezing the strips against the mold and then releasing the strips while holding them against downward movement until the longitudinal moving means has had time to pick up eachv successive strip as it returnsV to the 'starting position.-

f While my device is applicableV to many different types or type selecting-casting or setting machines, I have illustrated it in connection with a type casting machinewhe'rein a plurality of* matrix strips are mounted on an inclinedbed, these strips being associated with propelling means which draw them down inthe same direction they would travel under the' inilue'n'ce of gravity and propelling means releasing successive 30 strips when the strip reaches a point at which the desired character on the strip is in line with the moldA or other place where it is to be used. The propelling means having released each strip, other means come into operation to hold the stripin those holding vmeans let go, the strips may fall freely b y gravity until they reach the propelling means on its upward movement. In order to prevent this, my invention concerns itself primarily 5,5 Figure 4 is a detail view similar to Figure 2 but ing the parts in a different position;

A is a base having an upright frame YAllprejecting'therefrom and carrying a transmission 20 box Az adapted to contain a suitable motor and transmission mechanism. 4Extending from one vend oi' the Vbase A to the upright frame A1 isV a typewriter supporting frame A3 carrying. 'atypewriter'A. 'jAis alpattern bed, Aa'matrix bed, 25 the pattern bed having aplurality of pattern pins A? adapted to be selectively projected therefrom by' manipulation of the typewriter keys. v,"Ihe operative means therefor are not shown because they form no part of this invention, until the stop pins project into the paths of the latch heads Aa onthe matrix strips A9 which are arranged on their edges side by side for longitudinal move ment along the inclined path on the matrix bedA.- A B is a drive carriage adapted' to travel along the sides of the matrix bed being driven by means of a lever B1 and pivoted at one end on the base A.

Connected atthe other end to thedrive carriage by means of the' link B2, a crank B3 having a roller Bf engages a slot B5 inthe drive lever. Rotation of the crank causes reciprocation of the drive carriage B'carrying with it the notched pull bar B5 along the matrix bed. B'l is a latch in the latch -head A8 in the matrix strip or bar adapted toen- 45 gage the notch in the drive plate B5. This latch is pivoted in the head, the spring B8 holding it yieldingly'against engagement and disengagenrienty of the notched portion of the drive plate whereby the matrix strip may be caused to reciprocate by reciprocation of the drive carriage andplate.

It will be noted that the matrix bed A 'is cut away'intermediate its ends to permit the two mold parts C C1 to be locked in engagement with the moving matrix strips. C2 is the pot mouth which ,55

may be'forced upwardly by means not here shown to force'the mold against the matrix strips. C3 is a squeeze frame extending across the matrix bed Vabove the mold and it has a squeeze bar C4 which may by outside means not here shown be forced down against the matrix strips in opposition to the upper forcing of the pot mouth so that thestrips may be squeezed together and squeezed against the mold for casting. C5 is a lower and Ca an upper aligning bar adapted to engage the except that it will be noted that a sprocket C15 is driven by means in the transmissionhousing, and drives the chain C which in turn drives the sprocket C1 which sprocket drives a gear Clll in mesh with the gear C12 on the cam shaft C13 from which the squeeze mechanism and the aligning bars may be operated by any suitable connection not here shown.

D is a latch bar. It extends'across the frame above the matrix strips. Carried on this latch bar on a forward extension thereof are a plurality of pawls Dl loosely plvoted on a pin D2 and heldin the socket formed by the underside of the latch bar and the removable cover plate D4. There is preferably one of these pawls for each 'matrix strip. Each pawl has a downwardly extending tooth D* adapted to engage one of the serrations C" and when in the position shown'in Figure 4, these pawls are pushed down by the spring D as indicated and prevent downward displacement of the matrix strips when they are released by the lock When in the position shown in Figure 2, the pawls are lifted out of engagement. This is accomplished by means of a pivotally mounted spring bar D having a plurality of spring lingers D'I projecting forwardly into engagement with the apertures Da on the ends of the pawls. D9 is a lever associated with the pivotally mounted spring bar having a'roller D10 in engagement with the cam D11 on the cam shaft C13. D12 is a spring anchored at one end on the member D, at the other end on an extension D13 of the lever tending to hold the roller against the cam and so when the cam permits it to force the springs into the down position to permit the pawls to engage by gravity with the serrated matrix strips. When in the up position the cam exerts a tension on the' spring D12, lifts the lever D' up and the springs D'I liftvthe pawls into the upper position as shown,l in Figure 2.

The spring bar is supported on the latch bar by means of the adju-Stable screw pms E engaging each pawl D1 is engaged by a relatively stiil.'

adjustable trunnions lil1 in the latch bar whereby a wide range of transverse adjustment of the spring bar with its associated springsis permitted to assure alignment of the latches and the springs.

In Figures I and 8 is shown the method of supporting the springs on the spring bar. The flat plate E2" being in` opposition to the notched edge EJ of the spring bar D", each spring being held between the two in the notch, the plates being drawn together' by the cap screw E4 thus proviciing for a simple, convenient adjustment or removal of the springs.

It will be understood that as the pull bar makes its downward excursion and the successive matrix strips are engaged by the stop pins and so caused to be detached from the drive plate, that it is only when this operation has been completed that the aligning bars come into operation to, if necessary, move the matrix strips down slightly to bring them in alignment with the mold. Thereafter the mold and the squeeze bar are brought together and still later the pattern pins are moved out of line with the matrix strips. While the casting operation takes place, that is, immediately after the squeeze has been started and the strips no longer need to move, the control cam for the latch mechanism in its angular excursion permits the latches or dogs to assume the position shown in Figure 4 which they retain while the casting is taking place and after the squeeze pressure has been removed and after the aligning bars have been removed from engagement with the matrix strips until. the drive plate has picked up all the 'matrix strips and moved them back to the starting position so that during the succeeding cycle. the roller may be engaged by the cam and the latch dogs be moved into the position shown in Figure-2 so as to make it possible for the matrix strips to go down on the next cycle of operation. It will be Anoted that the purposeV of the springs associated with the latch dogs is merely to provide a convenient and easy means for lifting them out of engagement or for yieldingly hunting or 4tending to yieldingly limit their angular excursion. The springsl however, do not exert any downward pressure on the dogs, gravity doing that. This arrangement being made in the inter- `est of silence because a spring pressed dog as it clicksover each serration would be very much more noisy than a gravity held dog.

While I have illustrated my invention Vas applied to a matrix strip wherein a single continuous strip is used having a plurality of characters in intaglio from which type slugs are to be cast, it is obvious that under some circumstances the matrix strip might be divided into a plurality of separatemembers even one for each character. It is equally obvious lthat so far as my invention is concerned, it makes no difference whether the characters are in intaglio or relief. If in intaglio, they will be used for casting a slug from which printing will take place later or if in relief they might be used for embossing or printing direct. It is equally obvious that the holding and controlling mechanisms which form the basis of this invention'while shown applied directly to the back of the serrated matrix strip'might equally well be used with any serrated strip whether, it be matrix strip, printing strip, embossing strip or even a separate propelling strip which does all the work.V

In the modiedform shownin Figures 9, and 11, it will be noted that instead of having a separate spring member to control each pawl,

tapered strip G, which strip projects from the rock bar G1, the means for operating this bar being identicalwith the means for operating the spring bar D. It will be noted that the pawls are narrower than the matrix and there is a washer G2 between each pair of pawls and the pawls are also loose so that they may move back and forth with their washers. 'I'he stop plates G3 limit such movement. 'I'his is for the purpose of permitting' the pawls to have a suilicient freedom of movement to take care oi'` matrix strips of different thicknesses, for instance, the same set of pawls may control strips with which pica or elite or other sized type may be used and it may happen that one pawl may be in line with p'arts of two matrix strips or that one pawl may be in alignment with one matrix strip only but inno case is there a matrix strip which does not have all or part of a pawl in line with it. Reierence to the drawings will show that at one point the tapered strip is in such position thatv the pawls are free to move up and down by gravvity to engage the matrix strips. In vanother posiv on the machine. She then pushesa button and the operating levers swing down carrying with them the matrix strip drive bar. Each matrix strip is yieldably held to the bar andV asv` each strip engages. its appropriate pattern pin, the bar vtraveling forward, the yieldable engagement releases, thematrix strip is held in place, the drive lbar going down to the bottom of its excursion until each strip has been released and is held by the stop or Apattern-pin. Then the aligning mechanism comes into operation and aligns the matrices with the letters. all in the same line.

'Ihe squeeze bar engages the matrix strips and the casting or printing-act takes place. As soon as this casting or printing act has taken place, the squeeze bar andthe aligning mechanism are automatically released and withdrawn. At the same time, the propeller bar comes up engaging successive matrix strips as. it reaches them. They automatic detentdog or. latch associated with each matrix strip holds the matrix strip against downward movement but offers no opposition to the upward movement of the matrix strip. This is accomplished because the cam which operates the battery of automatic detents, it will be noted is a short cam `and only permits o r causes movement of the automaticdetent strip into working position during the time subsequent to the engagement of the aligning mechanism and tothe time subsequent to the completion of the upward excursion ofthe drive bar. Thus the automatic detents are' not in engagement with the matrix strips beingheld well above them all the time that the matrix strips are going down into printing or casting position. g

It will be noted that there is one detentfor each matrix strip. Thesedetents are loosely mounted in their supporting bar, being held in place by a loose pivot pin. 'I'he spring bar with Aone spring associated with `each detent is rocked by the cam either into the up position when the detents are all raised above the m'atrices or into the down position when the detents areall permitted under the iniluence of gravity to engage the backs of the matrices and penetrate the "zov notches'therein. No spring pressure is normally used to force the detents against the matrices. The spring -is merely for the purpose oi-providing a smooth and ilexible operation of the` detents Yand for the purpose of flexibly limiting their up or down as the case may be.
