'UNETEQ CARL WINKLER, 0 BERNE, SWITZERLAND.
AUTOMATIC MACHINE FOR CASTING STEREOPLATES.
Application filed March 20,1923. Serial 1T0. 826,348.
To all whom it may come m: v
Be it known that I, CARL WINKLER, a citizen of the Swiss Republic, resident at Berne, in the Swiss Republic, have invented new and useful Improvements in Automatic Machines for Casting Stereoplates, of which the following is a specification.
In type-setting and line casting machines it is usual to lock the pump normally and only to release same when a set line is in front of the mould, in which case a spring puts the pump into action. A device of this kind cannot be used in an automatic machine for casting stereo-plates for preventing the molten metal from issuing before the mould is in thecorrect position, because in such. machines the part controlling the flow of the metal cannot be opened by a spring, but must be driven direct.
According to my invention I prevent splashing, or the emptying of the pot, in casting machines for stereo-plates of the special kind in which the mould is adapted to be moved tightly against the outlet of the metal pot, by putting the driving mechanism for moving the part controlling the flow of metal out of action when the form, for any reason. is prevented from reaching its proper casting position.
One construction of a casting machine showing the features of my invention is shown on the accompanying drawing, in which- Fig. 1 is a side elevation of the principal parts of the machine, and
Fig. 2 an enlarged view of the-release device alone. i
The mould, consisting of a core a and bed 7), is opened and closed by the motor 0 through the agency of the connecting rod d, and, in the closed position, the mould is pressed against the outlet of the pot 6.
By the same motor 0 the cock 7 for open ing and closing the outlet of the pot is moved, which is done by means of the crank g and connecting rod it.
According to my invention the connecting rod h is constructed on the telescopic principle, the two parts being adapted to be locked together by a pawl 11 pivoted to the outer telescopic part and kept in the locked position by a sprin 10 by its engagement with the notch w inthe inner telescopic art. To the mould is attached a tappet 1, w ich, during the oblique upward movement of the mould from its open position along the dot and dash center line into the closed position shown in Figure 1, lifts the pawl i out of engagement with the notch in the inner one of the two telescopic parts and thus unlocks the connection between the two parts of the connecting rod until the mould reaches the highest point of its upward stroke and presses tightly against the pot. In this position the pawl 11 falls under the influence of the spring it into the locking'position again, that is, it engages the notch of the inner telescopic part, so that, when the crank g to which the connecting rod h is attached,
rotates, the cock f will be opened and closed, and a plate will be cast. Should the mould not reach its top position shown in Figure 1, owing, for example, to something getting between the mould and pot, the t-appet I will prevent the pawl i from falling into the notch of the inner telescoping part, thus enabling the inner part of the connecting rod to move without moving the outer part. Consequently, the cock will not be operated by the rotation of the crank m.
When the mould moves down away from the pot the tappet Z turns about its supporting pin a and can then slide past the pawl 2'. without moving same.
In order to assure that the crank g and connecting rod it always have the same end position, so that the tappet and pawl will engage with each other during the upward movement of the mould, locking discs 0 and p are provided, which by engagement with each other, assure that the crank always 1 stops in the same end position.
What I claim and desire to secure by Letters Patent of the United States is:
1. An automatic machine for casting stereo-plates, comprising in combination, a pot having aslot in the bottom, a cock in saidpot to open and close said slot, a mould adapted to be moved against and away from said pot, a crank adapted to be periodically rotated, a connecting rod attached to said crank, a lever attached to said cook, a sec ond connecting rod attached to said lever and having a telescopic connection with said first connecting rod, a pawl adapted to connect said connecting rods to form one whole, a tappet on said mould adapted to release said pawl until said mould reaches its casting position, substantially as, and for the purpose, set f0 2. An automatic machine for casting position, substantially as,and for thepurstereo-plates, comprising in combination, a pose, set forth.
l pot having a slot in the bottom, a cock in In testimony whereof I have signed my said pot to open and close said slot, a mould name to this specification in the presencr of I 5 adapted to be moved against and away from two subscribing witnesses.
said pot, driving mechanism to open and I V i a close said cock and to lift and lower said 1 CARL WINKLER. mould, and means to release the connection. Witnesses-i 7 between said cock and driving mechanism SAMUEL GEORGE TRIPP,
