SPECIFICATION forming part of Letters Patent No. 746,415, dated December 8, 1903.
Application filed July 28, 1903. Serial No.'167,350. (No model.) i
machines of this class individual matrices, assembled or composed in line, are presented by a supporting device known as the first elevator in front of a slotted mold, which is closed tightly against the matrices, so that the slug or linotype cast in the mold will have the type characters formed in relief on its forward edge by the matrices. The mold is secured rigidly in a vertical disk, mounted to turn on an arm projecting laterally from a horizontal slide, moved forward and backward by a cam, so that before the casting operation the mold is driven forward tightly against the matrices and after the casting operation retracted therefrom in order to draw the. characters on the contained slug out of the matrices, after which the disk is given a partial revolution in order to bring the mold in front of the ejector-blade, which serves to drive the slug or linotype out ofthe mold and between trim ming-knives into a receiv-ing ga'lley at the front. Heretofore it has been customary after the mold-disk has been retracted and rotated to move itforward again in order to bring the mold as near as possible to the knives between which the outgoing slug is driven. It has been found, however, that for want of suitable support-at the front the disk was liable to yield in a forward direction if, as sometimes happened, the slug adhered firmly in the mold.
The aim of the present invention is to give the mold-disk a rigid support at the front during the ejection of the slug. To this end I modify the cam by which the mold-slide is actuated, so that in the second forward movement the mold is carried slightly beyond the original line, so that a surface on the molddisk adjacent to the mold is brought firmly againsta rigid support or bearing.
Figure 1 is a vertical section through the mold-disk and adjacent parts of the linotypemachine, showing the mold in position to cooperate with the matrices. Fig. 2 is a horizontal section through the same on the line 2 2. Fig. 3 is a similar section showing the mold in position for the ejection of the slug and advanced beyond the position shown in the preceding figures that it may receive solid support during the ejection of the slug. Fig.
4 is a vertical section on the correspondinglynumbered line of Fig. 3 looking toward the left.
Referring to the drawings, A represents the rigid frame of the machine, B the slotted 6 5 ally-extending arm in which the pivot or jou rnal E of the mold-disk is secured.
G is the vertical cam, grooved in its side face to engage a roller 9 on the upright lever H, pivoted in the main frame and acting through a stud g thereon on the slide D for the purpose of moving the slide, thedisk, and the mold forward and backward.
I is a horizontal slide mounted in the main frame and carrying at its forward end the ejector-blade J, which advancing from the rear serves to drive the slug or linotype out of the mold and between the trimming-knives K in the ordinary manner.
The mold is rotated intermittingly,as usual, so as to present the mold in a horizontal position during the casting operation and there after carry it around past the stationary baseknife M until it finally assumes a vertical position in front of the ejector.
The mold-disk is provided with hardened thimbles or bushings N, screwedfirmly into its face, which slide forward over fixed studs 0 on the main frame in order to hold the disk from turning and keep the mold in exact alinement with the matrices or the ejector, as the case may be.
Heretofore the groove in the cam G has :00
been of such form that the mold was moved forward after the casting operation the same distance it was advanced against the matrices before the casting operation.
When the parts were in the ejecting position, there was nothing to directly support the mold against forward movement and the disk was liable to spring and allow the mold to go forward whenever the ejector acting against the slug was subjected to excessive resistance. To overcome this difficulty, I make the groove in the cam G of such form that when the mold is moved forward the second time in the ejecting position it is carried forward beyond the casting-plane and until the bushing N bears at its front end solidly against'the shoulder on the fixed stud O. In this manner the disk is given a very rigid support immediately adjacent to the mold and the mold supported so that it cannot spring or yield in a forward direction.
While I prefer to employ the stud and the sleeve as the means of-thus supporting the disk, it is manifest that the only essential requirement is that the cam shall carry the mold forward until the disk at a point adjacent to the mold is brought to a solid bearingagainst a support on the frame.
It will be manifest to the skilled mechanic that the details may be variously modified in this regard without departing from the limits of my invention or changing the mode of action.
Having described my invention, what I claim is- 1. In a linotype-machine, a mold-carrying disk,a rigid disk-support, in combination with means for advancing the disk to force the mold against the line of matrices, and for subsequently advancing the disk a greater dis tance against a rigid disk-support, whereby forward movement of the mold isprevented during the ejection of the slug or linotype.
2. In a linotype-machine, the slide and the mold-carrying disk mounted thereon, in combination with a cam G, acting to advance the mold to one position preparatory to the casting operation, and to a different position preparatory to the ejection of the slug, and arigid support against which the disk is seated when in the ejecting position.
3. In a linotype-machine and in combination with the mold and a movable support therefor, an operating-cam constructed with portions of different radii,whereby it is adapted to advance the mold to different positions for the casting and the ejection of a slug, respectively.
4. In a linotype-maehine, the mold, its supporting-disk provided with bushing, and the slide carrying said disk, a rigid support for the front of the disk, in combination with a cam acting to carry the parts forward'until the bushing is seated firmly against arigid support, substantially as described.
5. In a linotype-machine, the main frame having a shoulderedstud O thereon, and the elevator to support the matrix-line, in combination with the mold and rotary mold-carrying disk, the horizontal slide supporting said disk, and the cam G, constructed as shown,
to carry the mold forward against the matrices, and to carry it forward a greater distance preparatory to the ejection of the slug. In testimony whereof I hereunto set my hand, this 7th day of July, 1903, in the presence of two attesting witnesses.
