TYPOGRAPHI GAL MACHINE IN VEN TOR Patented May 10, 1932 UNITED STA TE-S PATE CE .ANTHONY J. STOUGES, OF QUEENS VILLAGE, NEW YORK,.AS'SIG1\TOR T0 MERGENTHALER LINOTYPE COMPANY, A CORPORATION OF NEW YORK TYPOGRAPHICAL MACHINE Application filed January 4, 1930. Serial No. 418,466.

This invention relates to typographical machines,such as. linotype machines of the general organization represented in U. S. Letters Patent to O. Mergenthaler No. 436,-

1532,whereincirculating matrices are released from a magazine in the order in which their characters are to appear in print and then composed in line, the composed line transferred-to the face of a slotted mold, the mold "filled with molten metal to form a slug or linotype against thematrices which produce the type. characters thereon, and the matrices thereafter returned through distributing mechanism to the magazine from whichthey started.

Inithese machines, the transfer of the composed lines to the casting mechanism is effected by a so-called line delivery carriage which comprises a slide or bodyportion and a pair of vertical opposedline engaging finwithstand the shocks and rough usage to whichitisconstantly subjected in practice.

To this end, the two sections of the improved finger are fitted together byan elongated tongue-and-slot CODIIGCtlOILPIBSBHtlIlg cooperatingbearing and banking. surfaces located both above and below the axis ofthe hinge. In the preferredembodiment illustrated, the tongue is formed on the upper fixed. sectionof the finger, from which it depends,.and at its lower end is beveled oif to afford .an additional banking surface below the hinge for locating the lower hinged section of the fingerin itsnormal vertical position, Whilesaid lower section is slotted to receive the tongue: and has its upper end on opposite sides of the slot beveled off to cooperate with banking surfaces formed at the lower end of .the fixed section and located above the hinge. Certain other improvemcntsintheconstruction of the finger are also contemplated, but these will best 'be understood from the detailed description to follow.

Inthe accompanying drawings, the invention is shown-merely inpreferre'd form and by way of example, and obviously many changes and variations may be made therein and in itsmode of application which will still be comprised within its spirit. .It should, therefore,.be understood that the invention is not limited to any specific form. or embodiment. except insofar as such limitations; are specified in-the claims.

Referring to the drawings Fig.1 is afrontelevationof a portion of a linotypexmachine equipped with the present improvements g r Fig. .2- i-s a fragmentary front view, showing the linetransfer carriagedn the course of its returnmovement and depicting' the relation which the left-handfinger bears to a justified'line a i Fig. 3-is a perspective view'ofthe improved lefCtI-hand finger and its supporting block, an 1 Fig. tisaperspective view, partly broken away, ofJsaidkfinger detached.

The-matrices X, when released fromtheir storage magazin'e (not shown), are delivered in the usual way to :the assembling elevator A, wherein they are composed in line, to-

gether with the'spacebands Y,-under the influence of'the star wheel A Aftercomposition, the elevator A is raised into registration withthe intermediate channel B and the composed line positioned between the long and short fingers of the delivery slide C, which then carries the line through-said channel and-intothe casting elevator D. The elevator D thereupon descends to present the composedzlinebetween-the clamping jaws E for the slug casting operation, the line being justified-before casting by-the vertically movable bar F, which in rising is adapted to. drive the -spacebands upwardly through the line so as to expand it against the jaws (see Fig. 2). The foregoing parts and their mode of operation are so well known that any further description would be superfluous.

The line delivery slide C (Figs. 1 and 2) is mounted in the guideway O of the machine frame 0 and is moved to and fro by the power-operated lever G and the intermediate connecting link G The short right-hand finger C is rigidlysecured to the delivery slide C, whereas the long left-hand finger C is movable relatively thereto, being attached to a separate block C which is also slidably mounted in the guideway 0 In order to prevent damage to the space bands Y, which are occasionally projected by the justification bar F into the path of the long left-hand finger C during the return movement of the slide C (see Fig. 2), said finger is provided with a lower hinged section C which is adapted to yield as it engages the spacebands so that the finger may ride safely thereover. The hinged lower section C possesses the additional advantage that, when the line delivery slide is in its receiving position (as in Fig. 1), the section may be readily pushed aside to give access to the line in course of composition for making corrections, etc.

According to the present invention, and for the reasons before stated, it is preferred to supportthe hinged section C from below as well as from above its pivotal axis. Consequently (as best shown in Fig. l) the upper fixed section C is formed with a depending tongue C which extends a substantial distance below the hinge pin 0, and the lower section C is formed with a corresponding vertical slot C" wherein the tongue is snugly confined, the side faces or bearing surfaces 0 of the tongue contacting throughout their length with the adjacent side walls or hearing surfaces 0 of the slot, whereby the hearing surfaces mutually cooperate in rigidly supporting and sustaining the lower section of the finger against edgewise strains or displacement. At its lower extremity, the tongue C is formed with a banking surface 0 which (as shown in Fig. at) is beveled upwardly from right to left and against which a similarly beveled bottom wall 0* of the slot C is adapted to engage when the lower hinged section C occupies its vertical position.

Although the banking surface 0 may in itself be sufficient to sustain the lower hinged section C against facewise movement toward the opposing finger C the upper fixed section (3* is provided above the hinge 0 with additional banking surfaces These latter banking surfaces, as may be observed, are

beveled in the opposite direction and are.

formed at the lowerend of the upper section C on opposite sides of the tongue C so as to cooperate with the upper ends of the side walls 0 which latter are beveled to corre spond and are adapted to engage therewith as the bottom wall 0 of the slot C comes in contact with the lower banking surface 0 As a result of the above construction, while the lower section 0 may swing freely facewise about the hinge pin 0 to and from its normal vertical position, it will be rigidly suported and firmly restrained against movement in other directions. Moreover, since the tongue-and-slot connection extends considerably below the hinge, the bearing surfaces presented are greatly increased in extent and permit of a freer and easier swinging movement of the lower hinged section, eliminating all danger of binding.

As a further feature of the invention, the swinging movement of the hinged section C is yieldingly resisted by a pair of flat springs C C, which are permanently secured to the upper fixed section C, as by means of clamping screws 0, such as are ordinarily employed in attaching the whole finger C to the slide block C These springs serve to hold the hinged section C normally in its vertical position against thebanking surfaces 0 0 and, while their tension is such as to permit the section to yield readily when it is obstructed by a spaceband in the manner before indicated, they are sufficiently strong to sustain it against yielding when the delivery slide is in its receiving position and the lower section C is called upon to support and guide a composed line of matrices as it is raised to the transfer position. The spring C as may be observed (see Fig. 3), is considerably shorter than the spring C and is superposed upon the same so as to supplement the action thereof when the pivotal movement of the hinged section C becomes pronounced or exaggerated. this way, the resiliency of the springs C C is preserved indefinitely and any danger of the longer spring becoming strained or set, which might occur if used alone, is avoided. V In this connection, it may be stated that the flat type of spring employed is more desirable than springs of other types, since it takes up less room and is not so subject to accidental displacement.

As another feature of the invention, the improved left-hand finger C is also provided with means in the form of a light leaf spring C for applying a yielding pressure to the matrix line as it is carried upward between the fingers preparatory to its delivery to the casting elevator D. The spring 0 as will be noted (Figs. 3 and 4) is secured at its lower end tothe inner face of the lower hinged sectlon C .and diverges upwardly therefrom to a point opposite the upper section 0*. posed lines areof the proper length, the spring (3 is of ,little or no value and will be cammed aside by the line, but when the Ordinarily, that is, when the com-j line is excessively short, it acts to straighten up the end matrices if they happen to be tilted or twisted and will thus compact the line and prevent such matrices from falling through the assembler. By locating the spring C on the lower hinged section C the latter may swing from its normal vertical position without encountering any resistance or interference on the part of the spring.
