The invention relates to type-casting machines of the kind in which a mold of variable size is used, the size of the mold being automatically adjusted to suit the varying widths of successively cast types.

According to the invention the adjustment of the size of the mold is effected by the movement of a striker which drives the type matrices towards the metal in the mold, and the amplitude of this movement, on which the adjustment of the mold depends, varies according to the width of the type to be produced by each successive operation of the machine.

The invention is illustrated in the accompanying drawings, in which Fig. 1 is a vertical section showing one form of construction, and

Fig. 2 is a similar section showing another form of construction,

Figs. 3 and 4 are sectional views, illustrating a modification of a detail.

Referring first to the construction shown in Fig. 1,0tis a shaft with a wheel I) thereon, and the wheel has a flange withaseries of holes for slidable matrix carriers 01, 02, etc. Each matrix carrier is under the influence of a spring, not illustrated, tending to restrain it from radial outward movement. The wheel rotates above a mold d, which is of variable size, molten metal being injected into this mold through a duct e from a nozzle ,1. The mold is composed of two parts g, h, the part it having a horizontal portion hi and being horizontally adjustable. The duct e is in the part hr and is so formed therein that in all positions of the part the duct can receive metal from the nozzle and deliver the metal to the interior of the mold. The part g is fixed, but alternatively it may likewise be adjustable, an arrangement being made whereby, when the part h is moved for altering the size of the mold the part g is also given. an appropriate movement.

A stop 1' limits the movement of the part h in one direction. This part is engaged by means of a stud and slot with an arm 70 projecting from a double armed lever pivoted at Z. The lever has an arm m adapted to strike whatever type matrix is by rotation of the wheel placed over the mold d. Its other arm n is connected to a coiled spring 0 and has fixed thereto a plate spring 10 resting on a cam q.

The widths and lengths of the matrix carriers are correlated, in the sense that all the carriers of all the matrices of the same width are of uniform length, sothat the carriers of matrices of different widths are also of different lengths. In

their normal positions all the carriers project outwardly to an equal extent from the rim of the wheel I), as indicated at r in the drawings, and this involves, owing to the different lengths of the carriers, that some of them project inwardly from the flange more than others. It will be seen in Fig. 1 that the narrower matrix carrier 01 projects inwards from the flange to the extent 81 which exceeds the inward projection t of the wider matrix carrier 02.

The wheel b is rotated by means of suitable mechanism, which may be actuated by means of a keyboard, so that for each casting operation a selected matrix carrier is placed directly over the mold, as shown in the case of the matrix carrier 01 in Fig. 1. When the wheel has stopped in the selected position the cam q is rotated, as indicated by an arrow in the drawings, so that it lifts the lever arm n, with consequent downward movement of the arm m, which strikes the matrix carrier and drives it downwards. During this movement of the lever the arm is is swung so that by shifting the part h, in of the mold it adjusts the size of the mold cavity to suit the width of the matrix. As the movement, which the lever makes is limited by the impact of the matrix carrier with the mold, its amplitude depends on the length of the matrix carrier. When the lower surface of the matrix carrier strikes the front of the mold, the mold is already closed and the matrix cannot pass into the mold, but is pressed against the front of the mold. Thereupon molten metal is injected into the mold for casting the type. When the cam has cleared the plate spring p the lever and the parts h, hl are restored to normal position by the spring 0, and the matrix carrier is also restored to normal position by its spring.

In the case of a shorter matrix carrier such as 02 the lever and the arm k make a longer movement, so that the mold capacity is adjusted to suit a narrower type.

In the construction shown in Fig. 2 the matrix carriers are all of the same length but have notches u u into which the tip of the driving arm m engages, and these notches are of different depths, so that as regards the movement of the lever the effect is the same as if the matrix carriers were of different lengths.

In the modification shown in Figs. 3 and 4 the lever arm m does not strike the outer ends of the matrix carriers 0 0 but strikes bosses v projecting laterally therefrom, the distance a: between the lever arm and the boss varying in the case of matrices of different widths.

It will be understood that the slidable matrix carriers are not necessarily mounted on a wheel, as other means may be used for placing them over the mold.
