Machines and Means for Making the Same,v

of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a art of this specification.

y invention relates to improvements in printing machines and means for making the same and is especially concerned with improvements in that type of machine commercially known as the multigraph.

It is often desirable to use cuts or prints in connection with the mult-igraph machine. Heretofore these cuts or prlnts have been prepared by the electrotype process and as a result they are not only expensive but more or less delay is experienced in procuring them.

The cuts or prints formed by the electrotype process are of annular cylindrical shape and are secured to the segment of the print ing machine either by means of bands engaging the edges of the prints or cuts or where the prints or cuts are of less width than the printing segment, by means of clips having T-shaped heads for engaging the correspondingly shaped slots in the segment of the machine and an overhanging lip or projection for engagin the edge of the print or cut. Considerable ifiiculty has been experienced in the use of such cuts because of their tendency to slip on the printing segment and thus throw them out of alinement. Furthermore, the reproductions produced by cuts secured to the printing segment heretofore employed are apt to be more or less indistinct, due to a slight movement of the cut during the printing operation.

The objects of my invention are:

(1) To provide a out having novel means formed integrally therewith for securing the cut to the printing segment of a printing machine, whereby the out can be easily secured to and detached from the printing segment and by means of which the cut W111 be rigidly held against displacement during the printing operation;

(2) To .provide a new article of manufacture comprising a cast out having ribs formed on the back thereof and integrally therewith, whereby thetcut can besecured to the rlntmg segment; v (3) 0 provide a cut for use on cylindrical printing segments which can be cast by means of the ordinary matrices used for making fiat cuts or prints for newspapers 0 other similar publications;

(4) To provide a cut for the cylindrical printingsegments of a multigraph machine which can be easily and quickly made; and (5) To provide a new and novel casting machine for casting the cuts referred to above.

Other objects will appear as this description progresses, references being had to the accompanying drawings in which Figure 1 is a side elevation of my improved casting machine.

Fig. 2 is an end elevation thereon.

Throughout the several views similar reference characters will be used for referring to similar parts.

Referring for the present to Fi s. 1 to 5 inclusive, my improved casting mac ine comprises a drag 10 which as shown in Figs. 2 and 3 is provided with a concave cylindrical inner surface which is adapted to receive and support a papier mach matrix 11, such as is used in-the preparation of prints or cuts for newspapers and other similar publications. Trunnions 12 extend in opposite directions from the upper edges of the drag 10 and are journaled in bearings 13 carried at the upper ends of the brackets 14.- The brackets 14 are secured together by means of a cross-bar 15 as shown in Figs. 2 and 3.

A cope 16 having a convex cylindrical Sui face co-acts with the drag 10 to form an annular cylindrical space 16 between the cope and drag for receiving the matrix and the curvature of the concave surfaceof the drag.

Side spacing strips 17 and an end spacing strip 17 (see Fig. 4:) are used for properly spacing the cope from the drag and for de- .position of the en limiting the,outline of the cut, that is,'-the h size of the cut is determined by the distance between the side spacing strip 17 which can be shifted longitudinally of, the space between the cope and drag.

A pedestal 18 extends upwardly from each of the trunnions 12 and a cross-bar 19 is secured to the upper ends of the pedestal 18 by means of the nuts 20. The cross-bar carrles a screw-threaded nut 21 into which is threaded a screw 22 having the handle 23 at its upper end. The lower end of the screw 22 is adapted to bear upon a bar 24 extending transversely of the cope. By means of the mechanism just described. the cops can be firmly clamped to the drag and then released when the casting operation has been completed so as to expedite the removal of the cut from the cope.

From an inspection of Figs-4 and 5 it will be noticed that the cope is provided with an end member 25 which inclines upwardly away from the space between the cope and the drag and that the drag is provided with an outwardly extending flange 26 which inclines in an opposite direction from the end member 25 of thecope. These two members co-act, when the mold is tilted to the position shown in dotted outline in Fig. 4, to form a trough or channel for receiving and directing the molten metal into the space between the cope and the drag. If desired, the

the space between cope can be hinged to the drag as shown at 27 in Figs. 1 and 4. A. pin 10 is conveniently provided on the drag 10 to co-operate with a standard 10" when the matrix is being assembled in the drag, the cope having of course been removed. The drag is thereby prevented from tilting during the make ready operation.

As shown in Figs. 1 and 3, the cope is to vided with spaced longitudinal exten ing T-shaped slots 28 which open outwardly through the convex surface of the cope into the cope anddrag. As many of these slots can be used as desired, but it is necessar to make the s acing thereof the same as the spacing of t e T-shaped slots-on the printing segment of the machine with which the cuts produced by my casting machine are to be used. For'use'with the commercial multigraph machine, ll prefer to have the slots 28 spaced apart seven-eighths of an inch.

In using my improved casting machine,

tilted to the position sdpacing strips 17 and thenearest the paper which it is desired to reproduce by the cut is first placed in the conveniently by the standard 10"; the cope having been previously removed. The spacing strips 17 and 17 whereupon the cope sition and the screw 22 manipulated to clamp the cope and drag together; The type metal avlng been melted, the co e and drag are shown 1n dotted outline in Fig. a and the molten metal poured into the trough formed by the end member 25 and the flange 26. The molten metalthereupon flows into the space between the cope and drag, which is supported are properly positioned, 16 is then placed in pomatrix bearing the impression drag and quickly solidifies due to the chilling action of these two members. The screw 22 is thereupon manipulated to release the cope 16 which can be removed from the drag. The formed out is thereupon removed from the cope by. moving it lengthwise of the cope. The cut thus formed can be easily and quickly attached to a segment of a printin machine having slots of the same shape an size as the cut, by bringing the ribs formed on the back of the cut into registry with the ends of the slots and then moving the segment and cut longitudinally relatively to each other. A cut thus secured to a printing segment w1ll not shift during the printing operation. It will, of that the cost of producing a cut by the method described above cost of producing a cut by means of the electrotype process, and that. the cuts can be easily and quickly made whenever they are desired.

In order to prevent the cut formed by the process described above from sticking to the mold, I prefer to apply thin cocoanut oil or some other similar material to the surfaces of th: cope which come into contact with the cu.

On account of the comparatively small dimensions of the slots formed in the cope, and because ofmaking these surfaces very smooth, ll prefer to construct the cope in .the manner shown in Fig. 6, wherein the reference character 16 indicates aconvex cylindrical member having longitudinally. extending slots 28 milled therein. ll then secure to the convex surface of the member 16 by means of the screws 30 or any other suitable means, a strip of metal which thereafter has the slots 28 milled longitudinally thereof and inlregistry with the slots 28 thereby forming a plurality of strips, 31, the edges of which are in spaced relation and overhang the sides of the slots 28', thus forming thenecks of the T-shaped slots.

The strlps 31 are preferably formed of metal cope which facilitates this separation. If

4 course, be apparent is much less than the l for' any reason it'fbecomes .necessary, the screws 30 can be manipulated to release the strips 31 from the member 16. ofthe cope thus permitting the strips 31 to be removed from the member 16'- along with the formed out. The strips 31 can then-be individually removed or separated from the cut.

In Fig. 7 I haveillustrated a further modification in the construction of the cope wherein the sides 32 of the grooves 28' in the member 16' are beveled or inclined outwardly. This not only facilitates there- -Fig. 8. The thin edges thus the edges of the heads of the r bs-will conmoval of the formed out from the cope but produces a cut in which the sides of the heads of the ribs are beveled as shown :in roduced on tation within the scope of the. appended goope and drag. thus described my; invention,
