Specification of Letters Patent.

Patented Feb. 20, 1917.

Application filed September 12, 1916. Serial No. 119,653.

To all whom it may 'concem:

Be it known that I, CHARLES VAsroA, a subject of the Emperor of Austria-Hungary, and a resident of Long Island City, borough of Queens in the county of Queens and State of New York, have invented a new and Improved Type-Casting Apparatus, of which the following is a full, clear, and exact de- 'scription.

This invention relates to metallurgy and has particular'refere'nce to novel apparatus forcasting type or analogous devices.

Among the objects of the invention .is to provide an= easily manipulated apparatus, whereby any block of material of special design, which will be referred to hereinafter under the general term of type, may be put into position for the formation of a matrix which may be preserved for the making at any desired time of any desired number of duplicate devices precisely like the original. With the foregoing and other objects in view the invention consists in the arrange- 'ment and combination of 'parts hereinafter i described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein,

still for the purpose of illustrating a practi cal embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a vertical longitudinal section on the line 11 of Fig. 3, showing applica 5 tion of my apparatus in the casting of a duplicate type in connection with the matrix; Fig. 2 'is an elevation of the. same, the

cover or casing being removed and the pat-- tern or form holding frame being lowered into horizontal position;

Fig. 3 is a plan view corresponding to Fig. 1, but with the casin removed Fig. 4 is a view su stantially on the line H of Fig. 3; 5 Fig. 5 is a plan view of the pattern showing the manner of securing the matrix;

,Fig. 6 is a vertical longitudinal section indicating the relation of the form and type to the metal chamber in the .formation of 0 the matrix;

Figs. 7 and 8 are perspective views of a type and, a matrix corresponding thereto;

oted at 27 upon the base for movement Fig. 9 is a perspective view of my special design of form block, and

Fig. 10 is a detailperspective view showing the manner of assembling the form blocks. 1 I

Referring now more particularly to the drawings, I show an apparatus comprising a base 10 upon which a casing 11 is adapted to beplaced, said casing having a vertical slot. 12 in one end.

Securedupon the base'10 is a melting pot 13 having legs 14,the body of the pot being elevated sufficiently to accommodate a Bunsen burner 15 or its equivalent, the tube of which leads through the slot 12. The body of the melting pot is bored vertically forming a chamber 16 to receive a mass of type metal of any suitable nature and a piston 17 is 70 fitted for reciprocation in said chamber 16. A lever 18 is pivoted at 19 upon upwardly projecting ears 20 secured to the upper end of the chamber body, and a link 21 loosely connected to the lever and the upper end of 75 the piston provides a means whereby the piston may be operated. The melted metal 22 is adapted to be forced upwardly and outwardlythrough a passageway 23 leading to a restricted mouth 24 at the upper portion of the pot 13. The mouth portion of the pot is faced by a plate 25, the outer surface of which is verticaL- At 26, I show a T-shaped bracket pivaround a horizontal axisparallel to the plane of the face of the plate 25. Said bracket is adapted to be swung outwardly from the body of the melting pot and ledsubstantially horizontal preliminary to the practice of the invention, the arms 26' of the bracket extending at right angles on opposite sides of the main portion of the bracket 26.

' 28 indicates a plate, shown as rectangular in form and pivoted upon a bolt 29 extending through its center and through the bracket 26. By means of a winged nut 30 or its equivalent, the plate 28 may be clamped in fixed position upon the bracket. Said plate 28 carries on two of its adjacent sides, flange members 31 which may be integral or otherwise rigidly secured'thereto, forming a right angle corner, with relation to which the filling blocks or quads may be screw 34, the axes of the screws being perpendicular to each other in practice and in a plane close to the active surface of the plate 28. One of the important features of my 1m- I provement consists of a plurality of form blocks 35, oneof which is shown in Fig. 9. I employ practically four of these blocks, all of the same construction. Each block comprises two parts or portions, one of which, is longer and thinner than the other, 35". The projecting end of the part 35 of each blocktakes under a shoulder formed onthe next adjacent block arranged at right angles thereto. By this means the blocks 35 all have a sort of interlocking engagement with one another, forming a rectangular space at the center, into which the type T'to be reproduced is locked by the application of the binding screws 34 against two adjacent blocks 35, as shown best in Fig. 5. The offset portions of the blocks 35 provide a chamber for the formation of the matrix of larger diameter than the original type. By reference to Figs. 6, 7, and 8, this fact. Wlll be appreciated. Fig. 8 indicates the matrix M of larger diameter than the type, the same being formed as shown in Fig. 6, in the enlarged chamber. By this fact, furthermore, a perfectly square shoulder is provided for the end of the type. By

comparing Figsrl and 6, it will be noted that the form blocks 35 are reversed accord-.

- chamber adjacent to the plate 28 for the formation of the matrix and afterward in boldtion bringing the outer edges of the form' blocks squarely against the face of the plate ing the matrix for reproduction of the type,

the larger caliber of chamber is next to the plate 28. The action of the clamping screws, however, s the same in both cases. Any suitable number orsize of quads Q may be used to properly position the form blocks with respect to the plate 28, so as to bring the type chamber in registry with the mouth 24 when the bracket 26 is swung into vertical posi- 25. In this position, the plate 28 and parts carried thereby are positively locked by means of a yoke 36 pivoted at 37 on opposite sides of the body of the melting pot. Said yoke is formed with notches 38 which take over the upper edges of the laterally projecting arms 26.

From the above detailed description of the mechanism, its. construction or manner of use may be briefly summarized as follows: Given any type T to be reproduced or to be provided with a matrix for future course, may be placed upon the surface of the type to prevent the matrix from sticking thereto After the matrix is formed in this manner and solidified, the operator will loosen, the nut 30 to permit the rotation of the plate around the axis of the bolt 29, whereby the comparatively thin neck of metal at the mouth 24 will be sheared off of the matrix by means of the plate 25. This expedient prevents any possibllity of distortion of the edges of the matrix where they coiiperate with the type which might otherwise be incident to the separation of the type and matrix. After the form blocks are loosened, however, the type and matrix may be separated with impunity with the exercise of ordinary care. The matrix thus herein for the formation of any number of type precisely similar to the original by an operation similar to that above described and indicated in Fig. 1.

I claim:
