No. 464,383 Claims priority, application Germany, June 18, 1964, L 48,076 Claims. (Cl. 199-13) D uring casting of a line of large size types in matrix setting and line casting machines, such as linotype machines, it has been noticed that the interior of the type slug during casting of large size types is not solidly cast, that is not completely filled with casting material. Such slugs are subjected during printing to premature wear and do not withstand the high printing pressure they are subjected to, and the slug is liable to sag in direction transverse to its elongation. These serious disadvantages can only be avoided to a limited extent by very extensive cooling of the mold in which the slugs are cast. These disadvantages can also not be overcome by increasing the casting pressure, since, due to the diiiiculties of providing a proper seal between the mold and the discharge end of the metal pot, as well as between the mold and the line of matrices thereon and between the individual matrices, the casting pressure cannot be increased to a desired extent. To overcome the mentioned disadvantages by means of a slug which has cross sections and dimensions so as to result in a small heat capacity and corresponding accelerated cooling, is connected with the disadvantages that the filling out of the depth of the characters, as well as the stability and the resistance against bending during printing will be greatly impaired in such a slug.

It is an object of the present invention to overcome these disadvantages in matrix setting and line casting machines during casting of lines of large size types.

It is an additional object of the present invention to provide in a matrix setting and line casting machine an arrangement permitting to cast lines of large size types in a perfect manner.

It is also an object of the present arrangement to provide for such an'arrangement which can be easily incorporated in a standard matrix setting and line casting machine.

It is a further object of the present invention to provide for such an arrangement which is composed of relatively few and simple parts so that the arrangement can be manufactured at reasonable cost and will stand up perfectly under extended use.

With these objects in view, the present invention mainly comprises in a matrix setting and line casting machine for casting lines of types of either large or small size, a mold for casting the line of types, magazine means containing matrices of different size corresponding to cast types of different size adapted to be transferred into casting position to the mold so that a line of types of desired size may be cast in the mold and ejected after casting and means for adjusting the time period between casting and ejection of the line of types in dependence upon the size of the type cast.

Preferably, the adjusting of the time -period between casting and ejection of the line of types, that is the time period during which the molding material injected into the mold is allowed to solidify, is controlled from the position of the mold, that is by means of an element which moves the mold between a casting and an ejecting position. Especially suitable for this purpose is a cam disk which is connected by a drive to the turnable mold disk to turn therewith and which, in dependence on the respective mold section on the mold disk which is brought during turning of the mold disk into casting position, closes an appropriate switch. An essential advantage of ICC such an arrangement is that the desired delay between casting and ejection of the line of types from the respective mold section is directly coordinated to that mold section for which the extended cooling of the mold material is desired.

According to the present invention, it is however, also possible to control the delay between casting and ejection of the line of types in dependence upon the transfer position of the magazines, that is the delay is produced when a magazine containing large size matrices is in a transfer position in which the matrices are adapted to be transferred to the respective mold section of the mold disk so that types of correspondingly large size may be cast therein.

The arrangement for adjusting the time period between casting and ejection of the line of types preferably includes an electromagnet or solenoid which is operatively connected to a coupling forming part of transmission means between the drive of the matrix setting and line casting machine and a cam shaft carrying the cams for controlling the various elements of the machine. The electromagnet is energized over a time delay relay, which is preferably adjustable, so that the time period in which the drive to the cam shaft is interrupted may be adjusted in a desired manner. Such an arrangement is not only extremely simple, but has the further advantages that such an arrangement can be easily incorporated into matrix setting and line casting machines of standard construction.

The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be 'best understood from the following description of specific embodiments when read in connection with the accompanying drawings, in which:

FIG. 1 is a schematic illustration of the arrangement according to the present invention;

FIG. la is a schematic illustration of another arrangement according to the present invention; and

FIG. 2 is an enlarged partly cross sectioned view illustrating the coupling means and the solenoid cooperating therewith.

Referring now to the drawings, and more speciiically to FIG. l, it will be seen that the arrangement according to the present invention includes a plurality of superimposed 4magazinesZ respectively containing matrices of different size. The magazines 2 are shift-able in a known manner by means of an elevating member or shifting means 1 to bring a selected one of the magazines 2 in a transfer position in which matrices contained therein are adapted to be transferred in a known manner, not forming part of the present invention, to one of the mold sections 40a, 40b 40C or 40d of a mold disk 40 schematically shown in FIG. 1. One or more cams 3 are fixed to the elevating member 1, adapted to cooperate with a microswitch 4 arranged in fixed position adjacent the elevating member 1. The number `of cams 3 and the positioning thereof on the elevating member 1 is such that during movement of .a magazine 2 which contains large size matrices to the transfer position, the respective cam 3 will move the normally open microswitch 4 to its closed position.

A circuit in which connection the casting delay is effected in dependence on the position of the mold disc can be seen in FIG. 1a. The mold disc 40 carries for each mold which requires time delay contact cams e.g. 3a cooperating with the fixed microswitch 4a. In this example contact 3a belongs to the mold 40a. The `cam 3a actuates the microswit-ch 4a if the mold 40a is in its casting position. In principle this circuit is analogous 3 tothe circuitshown in FIG. 1 in which thetime V-delay according to the invention is independent from the position of the magazines.

The'microswitch 4 forms part of an electric `circuit for energizing an electromagnet or solenoid 7. The circuit includes further a second normally open microswitch 5 `and a time delay -relay 6, which is preferably adjustable so that upon closing the microswitches`4 and 5 the solenoid'7 is energized for a time period corresponding the time set in the time delay relay 6. The solenoid 7, when energized, acts by means of a lever on a ring 111, slidably guided on .a shaft 17 for movement in axial direction thereof, and the ring 11 is connected as.

schematically shown in FIG. 1 to la coupling rod 12 slidably guided in an axial bore of the shaft 17 so lthat during energizing of the Vsolenoid'7 and movement of the armature thereof in direction of the arrow A, that is `toward'sthe left as viewed in FIG."1, the ring 11 and the fcoupling rod 12 connected thereto is moved towards .the right, as viewed in FIG. 1, against the actionof a compression spring'13 which tends to shift the coupling rod -12 towards the'left as viewed in FIG. 1. The right lend lof the coupling rod `12, as viewed in FIG. 1, which Aprojects beyond the shaft 17, is connected by means of .leversto'a pair of friction shoes v14 of Va friction clutch which are adapted to engage an annular inner :face 15 .of a; belt pulley 16 which Vis driven over ia belt drive,

--1 as-l'viewed vin FIG. 2, into the shaft in which a coupling surface 15 of the pulley 16 so that the drive from the latter to` the main'k shaft 17 is interrupted.

The shaft 17 carries xedly connected thereto a gear 18 for rotation therewith, which in turn meshes with a gear 30 fixed to a cam shaft' 31 which carries in a known manner a plurality vof cams for controlling the 'movements of the various components of the. matrix setting and line casting machine in a known manner. A cam 32 xedly mounted on the cam shaft 31 for rotation therewith has-a pair-of

gear segments

32 and 32" successively cooperating with a gearing 33, schematically -shown in FIG. 1,` to move la mold section on the turnable mold disk 40, provided with a gear meshing with the gearing 33, in a known manner between a casting position in which 'casting material is injected'from a melting pot not shown in the drawing into the respective moldsectionin lcasting position, and an ejecting p0- sition for ejectinng the cast slug from the lmold section.

The.cam shaft. carries further'a cam `9 which has 4a cam portion 8 adapted 'to cooperate with the microswitch 5 on any other of the cams provided on the cam shaft,

which are not shown in the drawing, and which cooperate with the other elements. of thematrix setting and line casting machine in a known manner to control the movements of the elements of the machine. Regardless where the cam portion 8 is provided, it has to be arranged in such a manner that the microswitch 5 is closed whenever an appropriate mold section of the mold disk 40 is in the casting position.

FIG. 2 shows the arrangement of the coupling means `for coupling the pulley 16 to the shaft 17 as well as the arrangement of the solenoid 7 vfor disengaging the coupling' means in further detail.

The shaft 17 shown in FIG. 2 is mounted on the frame I u rod 12 is slidably guided, protruding with its right end, as viewed in FIG. 2, beyond the shaft 17. The coupling rod 12 is normally pressed by means of a 4compression spring 13 which engages with one end thereof a collar xed'to the rod 12 and with the other end thereof a sleeve xed to the right end of the shaft 17 through which the rod 12 extends toward the right, las viewed in FIG. 2, so that a pair of pressure shoes 14 of a friction clutch arrangement .are pressed, by means of the levers 14 connected to the right end of the coupling rod 12 in the manner as clearly shown in FIG. 2, against an annular inner face 15 of the pulley 16 mountedvfor free rotation on the outer surface of the shaft 17. The pulley 16 is driven by a belt drive, not shown in the drawing, from a motor of the machine, which mot-or is likewise not shown in the drawing, so that in the position shown in FIG. 2 the shaft 17 is driven from the pulley 16 over the friction clutch 14, 1-5. Fixed to the shaft 17 is a pinion 18 which meshes with a gear 30 mounted on thev cam `shaft 31, as shown in FIG. 1, which in turn operates in a known manner the various components of the matrix setting and "line casting machine by meansof cams and gears mounted thereon. The disengagement ofthe

rfriction clutch

14, 15 is carried out during normal operation of the machine by means of fa ring 11 which is slidably guided on the shaft 13 and which is connected by a pin 19 screwed at one end into an appropriate bore of the ring 11 and extending through a cutout in. the .shaft 17 rand through an appropriate bore in the coupling rod'12. The lever mechanism for normally moving the ring 11 to the position uncoupling the

friction clutch

14, 15 is not illustrated in FIG. 2, but FIG. 2 illustrates Ionly the mechanism used to move the ring 11 to the uncoupling position for obtaining a desired delay of movement of the mold disk `from the casting to the ejecting position. This -arrangement includes, as `described before, the solenoid 7, the armature of 'which isv connectedv by means of .a rod 20 to za two armed lever 10 which is pivoted intermediate its ends at 22 on a projection of a plate 23, which in turn is'xed to the machine frame, as schematically indicated in FIG. 2, and which carries Ialso the solenoid 7- in the manner as shown in FIG. 2.' One yend' of the lever 10 is pivotally connected to a fork 21 xed to the rod 20, whereas the lother end of the lever 10 engages one end of a bolt 24 slidably guided in a bushing provided on the upper end of the plate 23. 'The other end of the bolt 24 carries a ball hearing 25 and the outer rin-g 26 of the ball bearing rollingly engages an abutment face 27 of the ring 11.

The operation of the arrangement described -above'will be obvious from the above description. If a magazine 2 containing large size matrices is shifted to the transfer position by means of the elevating member 1, the cam 3 located on the elevating member 1 will close the normally open microswitch 4. The matrix setting and line casting machine is then operated in the normal manner so that a line of matrices istransferred to an appropriate mold section of the mold di'sk40, which mold section is brought in a known manner in a casting `po sition in which casting lmaterial isvinjected in a known manner in the appropriate mold section. `The various elements'of the matrix vsetting andA line casting machine are thereby' operated and-controlled from the' cams on the cam shaft 31 which is driven from the shaft 17, which in'turn is driven from the pulley 16 when the clutch means 14,':15 are engaged.. The movement of the mold disk 40 from lthecasting to the ejecting position in which the castslug is ejected from the mold is however de layed when large size matrices are c'ast, since when a magazine 2 containing -larg'esize'matrices is inthe transfer position2 the mioroswitch 4 will be closed by the cam 3 and the microswitch 5 will al'so'be closed by engagement with the-cam portion 8 when the mold section of the mold disk 40 to which the large size matrices have been transferred is in the casting position so that the solenoid 7 is energized over the time delay relay `6. Energizing of the solenoid 7 causes movement of the ring 11 towards the right, `.as viewed in FIGS. l and 2, to disengage thereby the friction clutch 14, 1S so that the drive from the pulley 16 to the shaft 17 and from the latter to the cam shaft 31 is interrupted and so that movement of the mold disk 40 from the casting to the ejection position is delayed depending on the time to which the time delay 6 is set. This will permit the molding material injected into the respective mold section containing the large size matrices to properly solidify before the mold disk 40 is turned from the casting to the ejecting position. After expiration of the time set in the time delay relay 6, the latter Iwill break the circuit, thereby de-energizing the solenoid 7 so that the friction clutch 14, lwill be re-engaged through the action of the compression spring 13 and so that the pulley 16 vwill drive the shaft 17 and the latter the cam shaft 31 so that the respective mold section of the mold disk 40 will be turned from its casting to its ejecting position.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of arrangements for adjusting the time period between casting and Vthe ejection of a type slug in a matrix setting and line casting machine differing from the types described xabove.

While the invention has been illustrated and described as embodied in an Iarrangement for `adjusting the time period between casting and ejection of a type slug in a matrix setting and line casting machine in dependence upon the size of the type cast, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various -applications without omitting 'features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of the invention and, therefore, such adaptations should and fare intended to be comprehended within the meaning and range of equivalence of the following claims.
