LIlYE-SLUG-CASTING MACHINE.

Specification of Letters Patent.

Patented July 18, 192

Application filed September 4, 1820. Serial No. 498,298.

To allow/2.019s it may concern:

Be it known that l, SUNKER A. llisnr, a subject of the llingoi' Great Britain, and a resident oi New York city, county and State oi"? New York, have invented certain new and useful Improvements in Linc-Slug-Casting Machines, of which the following is a specification.

My invention relates to the casting of line slugs and the object of the invention is to enable a single mold type casting machine to be used for the production of continuous unitary lengths ol typographical matter.

The invention involves a number of novel tleatures including particularly a special method of? permanently interlocking succeeding sections cast in the mold and the casting of the sections against a composed matrix, which remains in engagement with and travels along with the cast portion of the line slug.

These and other features or the invention will appear more fully as the specific-atioii proceeds.

The invention is particularly adaptable to a type, lead and rule casting machine like that disclosed in my companion application, Serial No. 16%l,199, and for that reason I have disclosed the same as applied to a machine of that character, but- I wish it understood that the invention is'by no means limited to that particular machine, and further, that the structure maybe modified as regards the present disclosure without departure from the true spirit and scope of the invention.

In the accompanying drawing:

Figures 1 and 2 are vertical. sectional views taken through the mold chamber at the machine, Figure 1 being taken on sub stantially the plane of line 11 of Figure 2, and conversely, Figure 2, being taken on substantially the plane of line 2-2 of Fig ure 1.

Figure 3 is a transverse sectional view.

of dill ercntcross sectional forms which can he produced in the mold.

Figure 6 is a plan view, illustrating the permanent integration. of the cast sections.

Figure 7 is a detail sectional view, illustrating the additional interlock obtained where the cast sections overflow the matrices.

In the machine disclosed, the mold chamher, as indicated at 10 in FigureQ, is initiallv defined by upper and lower opposed horizontal mold blocks 11 and 12. and side walls formed by the vertical slides and Li. hen the first section is cast, the slide 13 which operates in the upper mold block is loweed to cooperate with the lower mold block 12, and after this first section is cast, the slide is raised to the position indicated and stands there until the casting or the slug is completed.

cast,

the slide Ll which operates in the lower meld block 12, is retracted to permit pusher l5 to enter the thus opened side of the mold chamber and to expel the casting therefrom. The mechanism by which these-slides are thus operated is not disclosed and may be similar to that shown in the application referred to.

The metal may he introduced into the mold chamber at the back through a jet opening as indicated at 16, to produce the castings 17.

The permanent interlock between the cast sections is accomplished bynoviding the slide l l'with a vertical undercut rib 18 on the mold lace thereof, which iliorms an undcrcut channel or dove tail groove in the adjacent side of the molded product, as indi clued at 19 (seeparticularly Figure 4i).

The upper and lower mold blocks, as shown in vllligure 2. :lorm'in effect a packing channel. at the left of the mold chamber receivin the cast product as it is advanced from the mold chamber. Alter the first section is cast, and the slide 18 iswithdrawn, the "front wallet the mold is formed by the rear face of the casting just made and as this isthe side which has the undercut groove in it the metal is flowed into this undercut groove and the sections are thereby permanently and fixedly interlocl'zed.

In casting a typographical line slug, the matrices, which I have shown in detail at 20 in Figured, are composed in a holder or ,arrier 21 which is then slidingly engaged in 'Aiter each section is a guide-way 22 extending across the front of the mold chamber. 1 have illustrated this carrier in the form of an open frame, having ribs 23 at the upper and lower edges thereof engaging in the grooves 24-. provided at the top and bottom of the guide-way and have shown the matrices as held in. said frame by being engaged over the ribs 25 which are interrupted at one end of the frame, asindieated at 26, to permit the matrices being slipped late ally into the frame. The matrices when composed in the desired order and properly spaced, as by means of the blanks 27, may be held by a clamp screw .28 arranged to bear on the endmatrix.

As the casts are made, the metal congealing in the depressions of the matrices forms a temporary interlock between the cast portion of the slug and the matrix carrier, thereby causing the matrix carrier to advance in step, and as a unit with the slug being cast. The matrices thus remain in contact with the casting during the entire operation, giving the metal ample time to set and enabling the work to proceed rapidly and smoothly. When the line is east, the slug may be separated from the matrix, it being convenient for this purpose to entirely remove the matrix holder with the slug from the machine.

Means may be provided for stopping the machine or for giving a suitable indication when the slug is completed. Thus, I have indicated at 29 a switch controlling a power or signal circuit 30 and having an arm 31 standing in the path of travel of the matrix carrier and arranged to be operated thereby when the slug casting is completed. This switch mechanism may be adjustable, as I have indicated, to enable the device to be set for line slugs of different length.

The invention is particularly suited to the casting of oversize type face. This is accomplished by enlarging the mold cavity at the matrix end by means consisting in the illustration of opposed upper and lower gages 32 and 33, slidingly supported in the upper and lower mold blocks and adapted to be advanced or retracted by means of the thumb turns 3d, :35 which operate pinions 3G in engagement with racks 87 carried by such slides. These gage slides are further shown as secured in their adjusted relations by the set screws 38. i

In Figure 1, the lower gage slide 33 is indicated asretractedto' produce an overhang at the lower face of the slug. In Figure .3, the lower gage is shown as projected into engagement with the upper gage so as to cut off the forward end of the mold cavity and produce a shortened blank slug such as shown at the left in Figure 5. It will be evident that by retracting both slides, an overhang can be produced at both top and bottom of the slug, as shown at the right in Figure 5. This ability to enlarge the mold cavity at the matrix end maltes it possble to produce various forms of display type and other large units with a mold of only moderate normal size.

hen casting with matrices which do not register laterally with the sides of the mold chamber, as when the individual matrices are larger or smaller than the mold chamber, the metal may flow laterally beyond the bounds of the mold chamber, producing an excess, as indicated at 39 in Figure 7 This is of advantage, however, in that the section next cast will interloclr with the more or less irregular shaped excess, and thereby produce a bond or interlock directly at the type face. This, with the undercut interlock in the body of the slug, produces a firm, strong slug.

The mold is preferably adjustable, as in my prior application, to enable the casting of different body sizes and this, with the ads j ustability of the type face gages makes it possible to east typographical matter in a great many different sizes in a machine of only moderate size. It will be clear that pictorial as well as strictly typographical matter may be cast with this machine and I, therefore, wish it understood that the term "typographical, and in fact, other expressions employed herein are used in a descriptive rather than in a limiting sense, except for such limitations as may be required by the prior art.

Ordinarily, the engagement of the cast portion of the slugwith the matrix will be sutlicient to provide a driving connection between the two, but in special cases, for instance, with electrotype or half-tone matrix blocks where the depressions are relatively shallow, a positive drive for the matrix holder may be provided, as by equipping the ejector with a spring-pressed pawl 4.0 arranged to engage with properly spaced notches or teeth .41 on the matrix carrier. In the rearward stroke of the ejector this pawl will. simply slide over the toothed rib E23 on the upper edge of the matrix carrier, but on the forward stroke of the ejector, the pawl will take hold of the carrier and insure its traveling along in unison with the ejected portion of the slug.
