RESILIENT GUIDING MEANS FOR TYPE CASTING MACHINES Filed June 8, 1960 2 Sheets-Sheet 2 F9. f5 37 EH I WWI United States Patent 3,037,615 RESILIENT GUIDING MEANS FOR TYPE CASTING MACHINES Sol M. Cantor, 130 W. 46th St., New York 36, NY. Filed June 8, 1960, Ser. No. 34,699 2 Claims. (Cl. 199-27) This invention relates generally to line of type casting machines, and more particularly to means and method for preventing damage to the side walls of matrices used in the casting machines, of the kind known as Linotype and Intertype.
In presently known and used type line casting machines, the type forming matrices are released from a magazine by the depression of keys on the keyboard of the machine. The matrices, as they are released, are rapidly carried down a moving inclined belt and hurled against the side of the next previously positioned matrix in the line being set up in the assembling elevator by the assembler. In most of the characters, the depression in the shape of the printing character to be cast is very close to the side wall of the matrix, and when such border of the female type character impression is struck by the edge of the next matrix as it leaves the belt, an indent-ation or damage is created. Singly or cumulatively, the damage becomes so severe that when the matrices are placed to receive the liquid hot casting metal under pressure, the metal is forced into those damaged areas or lateral depressions disposed between the matrices, and fins are formed in the printing slug, the fins being between the type characters. When subsequently used for printing, hair lines are printed between the letters. This condition is intolerable in good printing, so that the matrices must be replaced, necessitating high expense.
It is known in the art to provide a deflector adjacent the point of impact, such constructions being exemplified by the United States patent to J. Tunaley, No. 764,167, granted July 5, 1904. While these devices have some utility, they are not entirely effective in controlling the path of motion of the matrices, and particularly fail during the placement of relatively heavier matrices which are used to form relatively wide type characters.
It is therefore among the principal objects of the pressent invention to provide an improved deflecting means of the class described which is particularly adapted to control the movement of relatively heavier matrices by absorbing a degree of the kinetic energy possessed by the matrices as the same are moved into position.
Another object of the invention lies in the provision of improved deflecting structure of the class described which may be incorporated into existing type casting machines without substantial alteration or expense, thereby permitting relatively Wide sale, distribution and use of the inventive structure.
Another object of the invention lies in the provision of a deflecting means which may be pivotally associated with respect to the assembling elevator portion of a line casting machine, and which may have incorporated therein a resilient component capable of absorbing much of the force possessed by the moving relatively heavy matrix.
A feature of the invention lies in the fact that frictional forces are utilized to absorb kinetic energy in addition to the resilient forces exerted by the above-mentioned resilient mean-s.
These objects and features, as well as other incidental ends and advantages, will more fully appear in the progress of the following disclosure, and be pointed out in the appended claims.
In the drawings, to which reference will be made in the specification, similar reference characters have been employed to designate corresponding parts throughout the several views.

In accordance with the invention, the device, generally indicated by reference character 10, is shown in FIGURE 1 in installed condition upon a conventional line casting machine 11. As is known in the art, referring to FIGURE 2, a first matrix 12 when discharged from a moving assembler belt 13, moving leftwardly as seen in FIGURE 2, travels in such a manner that a lower edge 14 strikes the side Wall 15 of a second matrix 16 which is already in the horizontal stack 17 in the assembling elevator 18. While some deflection and retardation may have been produced by a deflector 19, particularly in the case where relatively heavy matrices are used, the kinetic possessed by the matrix is not absorbed sufficiently to prevent substantial damage to the previously positioned matrices in the stack or row. These have been pushed into position to the left of the upper rear retaining wall 20 by a star wheel 21.
Referring to FIGURES 3 and 4, and in accordance with the present invention, in the assembling elevator 17, the front and rear lower matrix support rails 22 and 23 are not changed, but the upper front matrix support rail 24 is provided with a new deflecting cam member 25, which differs from the deflector 19 of the prior art, principally in its location with respect to the upper front support rail 24 and its pivotal resilient mounting.
As best seen in FIGURES 5 to 14, inclusive, the element 25 includes a deflecting cam member 26 having a relatively flattened cam face 27. The member 2 6 is arranged for pivotal motion on a shaft 28 which extends through a bore 29 in the elevator frame 30, as best seen in FIGURE 8. The shaft 24 is provided with a noncircular terminal portion 31 having a bore 32 selectively engageable by a pin 33. Again, as seen in FIGURE 8, the terminal 31 projects outwardly of the bore 29, and has thereon a frictional member 37 and a lever member 34 having a corresponding square bore 35 therein. Near the opposite end 39 of the lever 34 is a spring 38, the first end 40 of which engages a hole 41, and the second end 42 of which is connected to another portion of the elevator frame 30.
The operation of the embodiment is seen in FIGURES 3 and 4 in the drawing. When a relatively thin lightweight matrix 52 moves down the elevator belt, the operation is relatively simiiar to that seen in FIGURE 2, the prior art construction. However, when a relatively thick heavy matrix is positioned, the striking of the cam face 27 is with sufficient force to deflect the cam member 26 in a clockwise direction as seen in FIGURE 4, whereby a portion of the kinetic energy is absorbed by the friction member 37, and the remaining portion by the spring 38. Upon clearing contact of the cam face, the extended spring 38 contracts returning the cam member to its initial position as seen in FIGURES 3 and 5.
I wish it to be understood that I do not consider the invention limited to the exact details of construction shown and described in this specification, for obvious modifications will occur to those skilled in the art to which the invention pertains.
I claim:
1. In a line of type casting machine, including an assembling elevator having an entrance end and a matrixsupporting rail adapted to receive a plurality of type character casting matrices, the improvement comprising: a deflecting element having a cam member having an edge thereon, said cam member being pivotally mounted on said assembling elevator in the area of said rail for movement about an axis spaced from said cam member, and means interconnecting said member and said elevator for resiliently urging said edge into the path of oncoming matrices.
2. In a line of type casting machine, including an assembling elevator having an entrance end and a matrixsupporting rail adapted to receive a plurality of type character casting matrices, the improvement comprising: a deflecting element having a cam member having an edge thereon, said cam member being pivotally mounted on said rail, and means interconnecting said elevator and said cam for resiliently urging said edge into the path of oncoming matrices.
