I TYPOGRAPHICAL MACHINE.

- Application filed April 17,

This invention relates to typographical machines, such as linotype machines, wherein the circulating matrices in a composed order for a linotype are transferred from an assembling elevator into. a receiving channel of a vertically movable first elevator, which presents it to a mold to enable the type bar or slug to be cast therefrom.

In machines of this class various sets of matrices are employed, as, for instance, matrices bearing .a single character; matrices bearing two characters located at different levels thereon, matrices having large face characters, known as head letters or head 1 characters, for casting a slug having an extended width over a single line Width. Therefore, different matrix supporting positions are provided, whereby the matrices may be composed and maintained at upper or lower levels as desired, to locate the selected characters in operative position.

In the use of head letter matrices as having large face characters, it is a practice to assemble them at the usual or lowest 2 level in the first elevator and provide means for positioning the first elevator to an auxiliary position, or level corresponding to an upper level, with respect to a mold, in order to enable a type metal from the mold to properly reach all portions of such character. The positioning of the first elevator to an auxiliary position being generally accomplished by the use of a socalled fill ng piece, which when in operative position functionsto arrest the movement of the first elevator when it reaches -=that point in its descent at which the matrix will occupy a proper position with respect to the mold.

The filling piece also functions to control a socalled vise-automatic for stopping the machine in the event that the matrices were not properly positioned relatively to the mold, such control being also efiective when the first elevator descends to its normal position or point.

After the matrices in the first elevator have been properly positioned with respect to the mold, the mold moves laterally against the matrices, after which the casting is made.

As the throwing in of the filling piece is under manual control, it happens that the operator inadvertentlygfai'ls to make said throwin, so that the assembled matrices in the 1924. Serial No. 707,244.

first elevator are not-sustained in their proper mold registering position, resulting in the improper representation of the matrix line to the mold and hence producing a squirt, or causing damage to the parts or both.

lVith the present invention, when a line casting is to be made, which requires the first elevator to be sustained in an auxiliary position or level, the first elevator is automatically elevated or adjusted to a position for appropriately bringing the-matrix line to registering position with the mold, the mechanism for adjusting the first elevator being actuated by the mold in its movement toward the matrix line.

As a different mold is required for casting head letters from that of general characters, the machine is provided with a plurality of molds mounted on a disk, orrotated carrier, whereby the molds are selectively brought to a functioning position. Therefore, the mold carrier is provided with means for cooperating with the mechanism for elevating the first elevator, when the head letter mold is moved into its operative po sition, and adapting first elevator auxiliary positioning mechanism to be out of commission when the various other molds on the carrier are selectively brought to operative position. Therefore, an object of the invention is to provide means for automatically moving the first elevator carrying type matrices in a composed line, to an auxiliary position sustaining the matrices in an appropriate level for mold registry and cooperation therewith.

Another object of my invention is to pro-, vide for a machine of the class specified, a lever mechanism actuated by the forward motion of the mold, which will raise the first elevator a sufficient amount to cause it to cooperate with the mold in question.

Other objects and certain advantages will appear in the description of the drawings forming a part of this specification, in which:

Figure 1 is a front elevation of a linotype machine having my invention mounted thereon.

Figure 2 is a section taken approximately on line 22, of Fig. 1.

of Fig. 1, showing the first elevator in raised position and the present invention in operative position during the casting operation.

Figure l is a detail view showing means for adjusting the device.

Figure 5 is a sectional. view taken on line 55, of Fig. 3.

Figure 6 is a detail view of the device an mounted.

The present invention is applicable genorally to typographical machines, wherein matrices may be assembled at either of two levels, and positioned at either of two levels, in front of a mold adapted to cast slug or type bart-herefrom.

In machines of such capacity, the improvoment can be easily applied to the connnereial machines as an attachment; therefore, the machineorganization not distiu'hed or its general operationinterfered with. The first elevator for casting head letters permit-ted to descend to its normal position or level for functioning or controlling the 50* called vise automatic, which is in advance of tlle timed movement at the mold toward the composed line oi matrices carried lay the first elevator, the first elevatorbeingelevated to its auxiliary posit ionuby lever oeviees actuatedby the mold mechanism in its move ment toward the matrices. This, therefore, causes no interference in the general operation ofthe machine or the satet y" device em ployed for-its control* and avoids any manual control for the auxiliary positioning of the first elhvator.

Referring'to the drawings 1 indicates the conventional type UTE mold carrier for supporting a mold 52 or a plurality of molds spaced about the carrier. The carrier rotatable for bringing the several molds mounted upon the carrierselectively to an operative position. The mold bod below the mold cavity or cell 3 is provided with grooves las upper and lower, to respectively receive the lugs 5 of the matrices assembled in the. jaws of the lirst elevator 6. The elevator is slidingly engaged with the vise cap of the vise frame i". The mold and itscarrier, first elevator and vise frame are of standard commercial structure and their operation "\VGlllIliOWll in the art so that more specific illustration and description thereof need not be made herein for the purposes of the present invention;

Ilevermeclianism for raising the first elevator to its proper level is secured to the Block Son the vise frame 7. In this position, the levers do not interfere with other parts of the mechanism being mounted upon the block and securely attached to the vise frame.

This main lever mechanism comprises a toggle, lever, operated by a rod attached at its central pivot. More specifically, I mount upon a plate 10, the surface of which is eas -s4.

parallel to the line of motion of the mold disc, two spaced plates 11, 12, each provided with a semi-cylindrical recess 13. These roceases are opposite to one anothon, and in them are positioned the two members 14:, 15, oi my toggle lever. The ends 16, of these members Ll, T5, are semi-circular and fit intothe reo as 13 coopeatiug with them to form end pivots for the toggle. The lower one of these plates'th is secured to the plate 10 stationarily and the upper 12 is hinged, thus constituting said upper plate itself a .econd lever. This form of pivot is found light, staunch and economical, but othen forms of pivots are usable and are llltBlldhCh to be included withini the scope of, this lllr vention.

The rod 1"? WlllClLflChUitiiGS-hlKMtOgglUlGVGU is provided with beveled outer edges 18, which cooperate \vi thibearing attaclln'ients 19 to the plate 10 which foiun guides font/he rod.

On the other-u en of. this third lever 25 is w a lifting rod, 28iwhich extends upwardly through the vise" cap. 27 and terminates undorthe head 29*oftthe first cleva'torG, and is thus adapted toraise the same.

When my attachment is used, the mold disc moves forward, engages the rod, which operates the toggle, lifts the second lever, which in turn raises the third lever to which is attached the rod which directly lifts the first elevator, thus, whether the filling piece (not shown) is used or not, my mechanism positions the first elevator at the proper height so that the matrices properly'align with the mold slot.

The inherent characteristic of a toggle lever, that the rapidity of motion decreases as the 180 point is reached, causes rapid motion of the first elevator until approximately the correct height is attained, and then relative slow motion as the mold disc comes forward and fits its own groove over the lugs on matrices.

When the mold carrier is rotated to move the mold for the head letters out of commission the stud 22 is moved out of engagement with the rod whereby the lever mechanism is inactive, in any forward movement of the mold carrier.

Having described my invention, I claim:

1. In a type casting machine wherein selective molds are carried by a rotatable mold disc and register at different levels with a reciprocating matrix carrying elevator, the registration bein completed by a forward motion of the mo d disc, the combination of lever mechanism and an abutment, the lever mechanism being operatively attached to the vise frame to engage and raise the elevator above its lowest position and the abutment being provided on the mold disc in association with a mold registering at a higher level and positioned to contact and operate the lever mechanism as the mold disc moves forwardly to raise the first elevator to registering position when the higher level mold is in operative position.
