MACHINE FOR CASTING STEREOTYPE PLATES AND THE LIKE Filed Aug. 6, 1951 U222] Ma yar Patented May 2, 1933 Uhii'lfi STATES s er-es CARL WINKLER, OF BERN, S'WITZERLAND llIAGl-HINE FOR UASTL'NG STEREOEYPE PLATES AND THE LIKE Application filed. August 8, 1931, Serial No.
For machines for casting stereotype plates and backing electrotypes devices have been designed to prevent the casting device from being put into operation before the mold has been brought into the casting position. In actual practice such devices are not used to any extent, because it has been found simpler to move the mold and casting device by the same gear, in which case the mold is nec- 39 essarily always closed before the casting device enters into operation. A drawback, however, consists in the possibility that the par! used to hold the matrixthat is to say, the matrix lock when such is used and the side mold gauges-can be left open by mistake, so that they are injured in closing the mold.
lVith the object of overcoming this drawback the invention arranges for the lever for putting the drive for the mold into operation to be locked by a lever which is connected with the matrix lock and with the side mold gauges, or with one or the other of these alone, and only releases the starting lever when these parts have been brought into the correct position.
In the accompanying drawing which shows the in 'ention by way of example,
F 1 is a side elevation of the mold in the opened position and Fig. 2 is a similar view of the mold in the closed position.
The mold consists of the core a, which is fastened to the side frames 6, and of the mantle c which is adapted to be moved up and down in the side frames Z). In raising the mantle 0 against the core a the side frames Z are simultaneously tilted up somewhat about the pins (Z, so that the closed mold is pressed against the mouth 6 through which the molten metal flows from the pot into the mold. If the matrix lock 7 is not properly closed, or if the side gauges g are not turned down into the mantle 0, they would be bent when the mold is closed and raised towards the mouth e.
According to the invention the movable part of the matrix lock 7 and the side gauges g are adapted to lock the starting lever h by which the motor for moving the mold is put into operation. For this purpose is arranged 555,441, and in Germany August 22, 1930.
on the mantle 0 a two-armed lever i which with its free end engages behind the stop 70 on the movable part of the matrix lock f. The other end of the lever 2' is linked to a rod Z, which in Fig. 1 is pressed to the left by a spring m and is linked at its right end toone arm of a two-armed lever n which is also carried by the mantle c. The other arm of the lever n carries a set-screw 0, which, when the matrix lock f is open, presses lightly against a lever 79 (Fig. 1). This lever is connected by a rod 9 with a second lever 7" which under spring pressure engages under a stop 8 on the starting lever h.
On the mantle 0 there is further a pawl 16 5 which engages over a pin u on the lever z and holds this lever in the position in which the lever 1 looks the lever 7L.
As soon as the side gauges g are turned down into the mold they knock against one end of the pawls t and thus release the levers i. The matrix lock f is then closed by turning down the handle 1) (Fig. 2), in order to press the upper edge of the matrix lying in the mantle 0 against said mantle. At the same time the stop k will be moved towards the left from. the position shown in Fig. 1 into that shown in Fig. 2, so that the upper end of the lever i is moved, against the pressure of the spring m, towards the left. By this movement the set-screw 0 at the lower end of the lever it, turns the two levers p and r, so that the starting lever h is released. By then pressing down the lever 72. the drive can be put into operation in the usual manner.
What I claim and desire to secure by Letters Patent of the United States is 1. In a machine for casting stereotype plates, and the like, comprising a metal pot containing molten metal and having an outlet mouth, a mold adapted to be opened and closed and moved towards and away from said mouth, a matrix lock for holding the matrix in said mold, side gauges in said mold, and a starting lever to put said mold into operation, the combination of a locking part to mechanically lock said starting lever, and a system of levers provided on the mantle of said mold and adapted when moved by said matrix lock to transmit its motion to said locking part and thus to release said starting lever, substantially as and for the purpose set forth.
2. In a machine for casting stereotype plates, and the like, comprising a metal pot containing molten metal and having an outlet mouth, a mold adapted to be opened and closed and moved towards and away from said mouth, a matrix lock for holding the matrix in said mold, side gauges in said mold, and a starting lever to put said mold into operation, the combination of a locking part to mechanically lock said starting lever, a system of levers provided on the mantle of said mold and adapted when moved by said matriX lock to transmit its motion to said locking part and thus to release said starting lever, and a pawl adapted to normally hold said system of levers in inoperative position and to be released by lowering the side gauges into said mold, substantially as, and for the purpose, set forth.
In testimony thereof I have signed my name to this specification.
CARL WVINKLER.
