AUTOMATIC JUSTlFlER.

SPECIFICATION forming part of Letters Patent No. 571,809, dated November 24, 1896.

Application filed February 21, 1896. Serial No. 580,285. (No model.)

To all whom, it may C07L087'IL.

Be it known that I, ALFRED \V. STORM, a citizen of the United States, residing at New York, county of New York, State of New York, have invented certain new and useful Improvements in Automatic Justifiers, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to that class of justiiiers which are inserted between movable matrices in contiguity to the mouth of a mold for conjoint use therewith in casting a linotype from fluid metal.

The object of theinventiou is to furnish a justifier adapted to yield under compression when the matrices are compressed into a line of the required length and to maintain a closed joint at the face of the mold under all the varying degrees of compression to which the j ustifiers are subjected.

My invention not only provides a justiiier which is adapted to close the mouth of the mold under varying degrees of compression, but it also provides a form of just-ifier which requires no extraneous mechanism for its operation and may be moved about in the act of composition or distribution by the same means as the matrices themselves.

I have illustrated my invention in the annexed drawings in a form adapted for use in the lllergenthaler linotype-machine described in United States Patent No. 486,532, granted September 16, 1890; but it will be obvious from the appended description that it is applicable to other forms of type-setting and type-casting machines.

Figure 1 is an elevation, and Fig. 2 a section on line 2 2 in Fig. 1-, of a justifier embodying myimprovements in their preferred form, having the tongue made integral with the adj Listing-springs, with the mold in section adjacent to the tongue in Fig. 1, as also the abutment L. Fig. 3 is an elevation of the j ustifier constructed with a laterally-elastic body and with an auxiliary spring for the tongue. Fig. 4 is a vertical section of the same on line 4 4 in Fig. 3. Fig. 5 is a transverse section of the same on line 5 5 in Fig. 3 with the parts expanded, and Fig. 6 is a similar view with the parts compressed.

Fig. 7 is an elevation, and Fig. 8 a plan, of a justifier having the tongue secured to the body-plate by a springleaf formed upon the latter and by auxiliary springs fitted to slots in its edge. Fig. 9 is an elevation of the body-plate alone, showing the construction of such leaf. Fig. 10 is a diagram showing a mold in section, with a. line of matrices and justifiers assembled before the same with end jaws in readiness to clamp the line to the required length and the justiliers ex panded, and Fig. 11 is a similar view representing the line clamped and the justitiers compressed.

In Figs. 1 and 2, A represents the body or bed plate of the justifier, B the upper and lower walls of the mold, and B the slot or cavity of the same.

The connection of the mold with the melting-pot is not shown, as it is not necessary to the understanding of my invention.

(l designates the cavity or recess formed in one side of the body A adjacent to that edge A of the body which is shown in contact withthe mold, the recess being formed with a sloping end 0 close to such edge. Such sloping end is termed the front incline herein. The tongue D is formed with an inclined face D, and is supported normally with the inner corner of such face engaging the outer corner of the front incline G. The same means are used with the construction shown in Figs. 1 and 2 to support it normally in this position and for pressing it toward the edge of the bed-plate when retracted therefrom, such means consisting of spring-arms E, extended transversely from the sides of the tongue and secured within the bottom of the recess near its opposite ends by screws or rivets e, inserted through slotted feet 6.

The body of the ton gue, excepting the end formed with the bevel face D, is made thin, so as to bend under pressure, and the rear end is flexed toward the body-plate A and forms a tailpiece which lies in a recess or groove A, formed transversely across the bodylate A. The outer side of the tongue when in its normal position, as shown in Fig. 2, is parallel with the opposite side of the body A, and when the tongue is normally extended, as shown in Fig. 2, the device operates to separate the matrices an amount equal to its full thickness, as shown in Fig. 10.

The body A is shown with a central notch in the upper end, having teeth a to serve in distribution, as is common in the matrices employed with the Mergenthalerlinotype-machine, and the whole device may be made of suitable dimensions to cooperate with such matrices in the use of such machines. \Vhen thus used, the justilier would be distributed in a magazine similar to the matrices and would be discharged and assembled in the composed line by the same means used for assembling the matrices.

In Fig. 10 the ends 13" of the mold are shown, as well as the cavity 13, and a line of matrices M is shown in front of the same with three of the justiliers, upon which the letters A and D are placed to designate the body and tongue, respectively. An abutment L is shown upon the opposite side of the matrices from the mold, which in practice presses them firmly toward the latter. The jaws K and K are shown at opposite ends of the line for regulating the length of the same. The jaws are shown separated to receive the composed line in Fig. 10, while the jaw K is shown in Fig. 11 advanced to compress the line to the same length as the mold-cavity B, thus crowding the tongues D into the cavities upon the justifier-plates A and diminishing the thickness of the justitiers, as required.

It will be observed in Fig. 10 that the outer beveled faces of the tongues project into the mold-cavity, and that where they are partially retracted, as in Fig. 11, they lie in close contact with the inclined end of the cavity C, and thus maintain a fluid-tight joint of the j ustifier.

Alternative constructions for sustaining the tongue are shown in Figs. 3 to 9, inclusive, the recess or cavity in Figs. 3 to (3, inelusive, being formed nearly across the entire width of the body A and with inclined ends at both sides of the cavity.

The body A is formed with slits (Lextended alternately from opposite ends of the body parallel with the inclined ends of the recess C, and the entire bodyis thus rendered expansible when the tongue is pressed into the recess 0. The tongue D is formed of a straight bar with inclined faces at both ends and is sustained in its normal position by a spring-leaf d, which is cut from the body A at the middle of its width and bent at its head or free end, as shown in Fig. 4t, to embrace the middle of the tongue. The tongue is formed with a recess d upon its outer side to receive such head flush with its exterior surface.

The front and rear edges of the justifier are lettered A and A respectively, and a longitudinal slit a is formed adjacent to the edge A of the body, and the bevel at the rear end of the recess 0 is formed upon the strip upon the inner side of suchslit. The beveled ends of the recess press the tongue normally outward, but when the rear edge A of the justifier is in contact with the abutment L and the compression is exerted upon the composed line the tongue presses upon the inclined edges of the recess and expands the justifier. thus crowding the rear edge toward the abutment and partially closing the slit a adjacent to such rear edge, as shown in Fig. 6. The elastic resistance of the metal in the rear of such slit (upon the rear edge A holds the beveled face upon the front end of the tongue in close contact with the front incline C of the justilier, and thus keeps the joint closed at the mouth of the mold.

In Figs. '7 to 9, inclusive, the tongue D is formed of a straight bar with a transverse slot at the rear end, adapted to engage a crosspin 0, formed at the rear end of a spring-leaf c, which is cut from the body A in the bottom of the recess 0, as shown in Fig. 9, and bent upwardly, as shown in Fig. 8, to hold the rear end of the tongue normally elevated at the same level as the front end when the j ustifier is uncompressed. The front end of the tongue is held normally elevated by springs I), secured at their outer ends in the bottom of the recess and having their inner ends fitted to slots Z) in the opposite edges of the tongue. The leaf 0 and the springs b are adapted to yield when the justitier is subj cc ted to lateral compression, and the beveled face of the tongue is thus held in close contact with the inclined end of the recess during the act of justifying, while it is thrust forwardly and outwardly when uncompressed, like the constructions previously shown. In this construction it will be observed that the pin 0 upon the rear end of the leaf 0 operates to resist the end movement of the tongue, while the springs Z) operate to resist the inward pressure upon the same; but that the spring-arms E operate to resist both move ments with the construction shown in Fig. 1, while the spring-tailpiece of the tongue also operates to resist the inward pressure.

Vith the construction shown in Figs. 3 to 5 the edges lettered A and A upon the body of the j ustifier are drawn elastically together by the metal lying between the alternate slits a, and the elasticity of the body thus operates upon the inclined faces upon opposite ends of the tongue to force it outwardly, while the spring-leaf (I simply serves to retain the tongue upon the body.

All of the constructions perform the f unction of holding the inclined sloping face at the end of the tongue in close contact with the incline C at the front end of the recess C, thus permitting the tongue to be retracted within the recess as the j ustifier is compressed. while it effectively closes the mouth of the mold in all the variations of its thickness.

It will be understood that the tongue is moved longitudinally when projected out of the recess, which, in the construction shown IOC in Fig. 1, is effected by the reaction of the arms E, which yield when the tongue is moved longitudinally in the opposite direction in 1 the act of compression. The reaction of the spring-arms E thus moves the tongue out of 2 the recess by forcing the sloping face D lat- I erally over the front incline O, and simultaf neously projects the end of the tongue beyond 2 the edge of the just-ifier. lVhen the line of matrices with such justitiers is placed before the mold, the latter would be advanced and its sides I would embrace the upper and lower edges of the tongues, as shown in Fig. 1.

The tongue is projected from the edge of the j ustilier to enter the mouth of the mold before compression that it may be varied in thickness without retracting the tongue wholly from the mold, as such complete retraction would open a space by the side of the body A for the escape of the fluid metal. The construetion is, however, adapted for the tongue to be retracted even with the edge A, in which condition the mouth of the mold remains closed, while the justifier is compressed to its fullest extent, and the tongue would be in contact with the bottom of the recess. The recess is shown in Figs. 3 and 7 of sufficient width to accommodate the entire length of the tongue, while in Fig. l the recess is made wide enough to receive the arms E only and the tailpiece of the tongue is accommodated in transverse recess A"; but these variations are immaterial, as it is only necessary that space should be formed in one side of the flat body-plate A to accommodate the tongue when the latter is retracted.

The general outline of the justilier and the attachments or provisions for composing or distributing the same are immaterial to my invention and may be modified in any desired manner.

IIavin g thus set forth the nature of my invention, what I claim herein is- 1. In a justifier adapted for use with a line of matrices in casting linotypes, the combination, with a flat body having a recess upon one side with inclined end C adjacent to the edge of the body, of a tongue I) arranged transversely to such edge and provided with a sloping face D fitted to the front incline O, the tongue being constructed and operated to close the mouth of the mold continuously as it is retract-ed into the recess, substantially as herein set forth.

2. In a justifier adapted for use with aline of matrices in casting linotypes, the combination with a flat body having a recess upon one side with front incline G adjacent to the edge of the body, of a tongue D arranged transversely to such edge and provided with a sloping face D fitted to the front incline O, and means for holding the tongue normally above the recessed side of the bod y-plate with its end projected over the edge, as and for the purpose set forth.

In a justiiier, the combination, with a flat body having a recess upon one side with front incline 0 adjacent to the edge of the body, of a tongue D arranged transversely to such edge and provided with a sloping face D fitted to the front incline O", and springsupports holding the tongue upon the body normally lifted from the recess with its inclined face projecting from the edge of the body, as and for the purpose set forth.

4. In a justifier, the combination, with a flat body-plate having the recess 0 extended along one edge with front incline 0 adjacent to such edge, of the tongue 1) extended transversely to such edge with its outer side normally parallelto the body-plate and having the spring-arms E secured by slotted feet in the bottom of the recess, to hold the end of the tongue normally projected from the edge of the plate, as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

ALFRED IV. STORM.
