This invention relates to a machine for casting stereotype printing plates.
The principal objects of the invention are to provide means whereby the time required 5 for the insertion and adjustment of a new matrix when the casting box is open can be saved by putting it into position ready for insertion while the casting operation is going on; to provide means for supporting a matrix of such a nature that, while a cast is being made on a matrix in the machine, a new matrix can be made and clamped in position ready to be introduced into the box immediately after the box is opened; to provide a holding device capable of supporting two matrices at a time; to provide for moving two matrices endwise to remove the old ma trix from the casting box and introduce the new one already clamped, and to do this by a single simple straight line motion.
Other objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accompanying drawings in which Fig. 1 is a longitudinal vertical sectional view of a casting box constructed in accord ance with this invention;
Fig. 2 is a side View of the same shown with the parts in the opposite extreme posit-ion;
Fig. 3 is an end View with the parts in position for casting; and
Fig. 4 is a reduced sectional view showing the back lowered after casting.
I have applied the invention to a casting machine comprising a frame 10, a core 11 rotatable on a horizontal shaft 12, carried by the frame 10 and a reciprocating back 1?. The back 17 is operated by a crank shaft 13 which receives the power from any desired source and has two crank rods 14: which are connected with the back 17. This connection is shown as made through a pair of eccentric pins 15 having arms 16 thereon.
The box is guided to move in a vertical direction by a pair of vertical uides 20 which preferably are stationary and are received between guideways 21 extending vertically downward from the bottom of the casting box 17 On the back I provide a sliding frame 23 adapted to slide in dove-tail gibways 24L on the outside of the opposite straight sides of the back. This frame has cross bars 25 below at its ends to serve as operating handles and is provided with two sets of matrix holding clips 26 and 27. These clips are arranged at opposite ends of this frame to carry a pair of matrices. The clips are provided on the usual rods 31 and are operated by pivoted handles 32 as is well understood in this art.
The casting back 17 is equipped with two overhanging concave aprons 29 and 30 in which a matrix can be adjusted while the other matrix is in use for casting a plate in the box.
In Fig. 1 I have shown the frame shifted to the right so that the left hand matrix in the frame is in casting position. This matrix can be used for as many casts as may be desired and while that operation is going on the new matrix can be introduced into the frame at the right, the clips on that side operated to secure the edges of the matrix in the sliding frame. Then when it is desired to change t 1e matrices, the box is opened by lowering it, by means of the crank shaft or any other desired way. his leaves the parts as shown in Fig. 1. The clips 27 at the right are then turned down and the frame slid over to the left, as shown in Fig. 2, so as to bring the old matrix out into a position where it is accessible to the operator and the new one into casting poistion. Then the back is raised, closing the mold and bringing the matrix clamps into contact with the studs 34 to positively hold them.
It will be observed that the new matrix will not have to be adjusted or even clamped after it reaches that position. Now the old matrix can be removed and a new one placed in the frame while the casting is going on at the right hand end of the frame.
It will be understood, of course, that the rest of the casting box, including the end rings 35, are all of the usual construction and will not be described in detail.
It will. be seen that with this invention all the time now lost in inserting the matrix, inspection, removing and replacing it is saved and the only thing necessary to do when the casting box is not 1 operation, is to slide the frame from one o:- me position to the other. This allows an important saving at a time when the operation mus" be pro ceeded with as rapidly as possible.
Although I have illustrated and described only a single form of the invention and shown it as applied to a specific type of casting nnichine, I am aware of the fact that modifications can be made in the details of construction and that it can be applied to other types of stereotype plate casting machine without depart ng from the scope of the invention as expresse... in the claims, but what I do claim is 1- 1. In a stereotype plate casting device, the comljiination with a mold com rising a convex core and a concave back, of means whereby a matrix can be moved out of the mold in an axial direction and supported at the end of the mold.
2. In a. stereotype plate or sting box, the combination with the parts of the box, of means located between them for holding an old matrix, and guides for guiding said holding means to move out of the box in unchanged relation to each other with the matrix clamped to the holding means and a new matrix can be moved into the mold sinuilt-aneonsly.
3. In a stereotype plate casting box, the combination with a core and back, of a frame having means for holding a matrix clamped in position therein, and guides for supporting the frame so arranged that the frame can be moved longitudinally along the guides far enough to take the matrix out of the back.
4. In a stereotype plate casting box, the combination with the core and back, of a frame for holding a matrix in the back, guides on the back for the frame, and an extension on the back for su'p 'iorting the frame with the matrix thereon outside the back.
5. In a stereotype plate casting box, the con'ibination with the two parts of the box adapted to hold'a matrix between them, one part being mounted in stationary position, and means whereby the other part of the box can be moved back and forth to open and close the mold, of means whereby the matrix can be moved bodily outbeyond the box in an axial direction while still clamped in curved position.
(5. In a stereotype plate casting device, the combination with a core rotatable on a fixed axis, of a. reciprocable back co-operating with the core, means for holding the. matrix therein, said back being mounted to nove to a position away from the core, and longitudinal guides for guiding the matrix holding means to a position outside the back.
7. In a casting machine, the combination with a mold part, of a crank shaft, a pair of crank rods connected with the crank shaft and with the mold part for reciprocating the mold part, a pair of guides for said mold part, a matrix holding frame carried by said mold part, and means whereby the frame can be moved longitudinally until the matrix is located entirely outside the mold.
8. In a stereotylie plate casting machine, the combination with two mold parts, one mounted in stationary position and the other movable toward and from it, of means for moving the latter mold part toward and away from the stationary part, means for sup mrting a matrix in the movable mold part and guiding it outwardly therefrom atthe end, and means whereby when moved away from the movable mold part it will be supported in position so that its interior will be exposed.
9. In a stereotype plate casting device, the combination with a core, of a back, means for operating the back, a pair of guides in the back, and a frame carried bysaid guides and having means for holding two matrices at a time, one inside the back and one outside the back, said frame being movable back and forth to hold either matrix in casting position.
10. In. a stereotype plate casting device, the combination with a casting box comprising a core and back, of guides along the straight edges of the back, a frame slidably carried by said uides having clamps for holding two matrices therein at the same time, whereby said frame can be slid along the guides to two extreme positions in either of which one matrix is in casting position.
11. In a stereotype plate casting device, the combination with a core and segmental back, of guides in the back extending along the straight edges thereof, a semi-cylindrical frame carried by said guides and of approximately twice the length of the back, two sets of clamps on said frame, each set adapted for holding a matrix at the oppositeends of the frame, and extensions on the back at both ends for receiving the ends of said frame alternately as the frame is moved along the guides to two extreme positions in each of which one matrix is exposed.
12. In a stereotype plate casting device, the combination with a core, of a back, means for operating the back, and a frame, means on the frame for holding two matrices at a time, each of the full length of the mold, one inside the back in casting position and one outside the back.
13. In a stereotype plate casting box, the combination with the two parts of the box adapted to hold a matrix between them, of
means whereby the matrix can be moved bodily out beyond the box while still clamped in the shape which is assumed in the box and a new matrix can be moved into the mold simultaneously.
14. In a stereotype plate casting box, the
combination with the back and core, of means for holding a matrix in the back and means for simultaneously moving an old matrix out of the back in a longitudinal axial direction and a new matrix into the back whereby the matrix is charged and unloaded at the same time.
In testimony whereof I have hereunto affixed my signature.
