Claims priority, application Great Britain February 13, 1953 Claims. (Cl. 199-77) This invention relates to single-type casting and composing machines and to photo-typographical composing machines and refers particularly to machines wherein positioning mechanisms for a matrix-case or for a master character-plate, as the case may be, are controlled by a record-strip.

In such type casting and composing machines the matrices for any particular layout or font are arranged in a rectangular case, which is movable in two directions in the same plane to position the required matrix accurately over a mould and in the photo-composing machines, the characters are similarly arranged on a mastervplate adjustable in the same manner to position a character relatively to a lens for projection on to a light-sensitive surface. In both kinds of machines individual members of two series of gauges are selectively operated under control of the record-strip to govern the positioning mechanisms which control the movements of the matrixcase or master-plate, as the case may be.

The existing gauging and positioning mechanisms for the matrix-case or for the master-plate comprise two pairs of primary positioning jaw-carrying levers co-operating with two stepped series of separately operated primary gauge pins, each of which determines only one positioning point for a matrix-case or for a master-character plate. Each pair of these primary positioning levers adjusts a secondary gauge or stop, and, co-operating with each of these secondary gauges are two pairs of secondary positioning jaw-carrying levers one pair of which moves the matrix-case or master-plate in one direction to the position indicated by one of the secondary gauges and the other pair moves a carrying frame for the matrix-case or the master-plate in another direction to a position indicated by the other secondary gauge.

The present invention is particularly concerned with the primary positioning mechanisms and the primary gauges.

It is the chief object of the present invention to provide primary positioning mechanisms which can determine or dictate two positions of adjustment for a matrixcase or for a master-plate from any one or from a selected number of the primary gauge pins.

According to the present invention there is mounted on the normal jaw of one of the primary positioning levers a second or supplementary jaw which is loosely mounted on the normal jaw and placed in advance thereof and the mechanism controlled from the record-strip acts to render one or other of these jaws operative on any one, or on a pre-selected number, of the gauge pins of the series.

The invention will be described and illustrated as embodied in a die-case positioning mechanism of an existing single-type casting and composing machine, such as described in the specification of British Letters Patent No. 8,633/99.

Referring to the accompanying drawings:

In the existing machines there are, as already stated, two series of gauging and positioning mechanisms for the matrix-case or for the master plate and, as these two mechanisms are similar, a description of one will serve for both.

Each gauging and positioning mechanism of the existing single-type casting and composing machine comprises: a stepped primary gauge in the form of fifteen gauge pins A each operated by air from perforations in the record-strip, and a primary positioning mechanism comprising a pair of oppositely movable levers A1, A2, co-operating therewith. The lever A1 is furnished at its outer end with a jaw A3 provided on its forward face with recesses A1 (see Figs. 2, 3 and 6) and the lever A2 has pivoted to its forward end a jaw A5, which after the jaw A3 has contacted with a gauge of the series moves into contact therewith. The levers A1, A2 are coupled together at their rear ends by a link A6. Intermediate its ends the lever A1 is connected by a link A'I to a pivot pin A8 mounted on an arm A9 which is rocked on a stationary pivot A10. The lever A2 is coupled to a stationary pivot A11 by a link A12. When the rocking lever A9 is moved to the right as shown in Figure 1, the lever A1 is moved to the right until the jaw A3 contacts with whichever of the pins A is raised. The lever A2 is then moved until the jaw A5 thereon contacts with the opposed jaw A3. In closing on a projected pin of the primary group A, the jaws A3 and A5 carry with them the secondary gauge which is formed by a head or stop A13 on a sliding bar A14 and position this stop in line with the projected pin of the series A. On encountering the said pin, the lever A1 is arrested and the continued movement of the rocking lever A5 causes the lever A2 to advance towards the left until the jaw A5 carried thereon meets lthe jaw A3. During this closing movement of the levers A1, A2, the jaws A3 and A5 have moved the secondary gauge A13 into alignment with the raised pin of the series of primary gauges A. The sliding bar A14 is then temporarily locked by a toothed rod A15 which engages teeth on the bar. The secondary positioning mechanism which cooperates with the secondary gauge A13, comprises a pair of oppositely movable levers A16, A12, which carry at their outer ends respectively jaws A12, A19. These levers A16, A17, are coupled together at their rear ends by a link A2l1 and the lever A1r1 is connected to the pivot pin AB on the rocking lever A9 by a link A21 whilst the lever A16 is connected to a stationary pivot A22 by a link A23 (see Fig. l). During the closing movement of the jaws A3, A5, the secondary positioning levers A16, A17, have been opened by the movement of the rocking levers A9. On the return movement of the rocking lever, i. e. towards the left hand, the levers A1, A2, are separated leaving the secondary gauges A13 stationary and the levers A16, A17 are brought together until the jaws A111, A19 thereon encounter the secondary gauge A13. In closing these jaws A13; A19, encounter a stop BA connectedl to the matrix-case B1.v

The matrices b (see Fig. l) are arranged in columns and rows in the case Bl which is movable bodily in one direction in a carrying frame B2 which in turn is movable in a direction at right angles to the movement of the die-case. As shown in Fig. l the stop B is formed on the head of a draw-bar B3 attached toa slide B4t in a slot in which a nose B5 on the end of the die-case B1 is free to slide in company with the frame B2 in which it is mounted.

In the commercial machine, to which the present invention is applicable, there are fifteen` pins in the series Vof the primary gauge A and correspondingly there are fifteen columns of matrices b in the die-case B1. Thus one pin is useful only for positioning one row of matrices. In this machine also the gauging and positioning devices described above are,.as already stated, duplicated for positioning the frame B2, so that by the combined movements of these two groups of positioning and gauging devices a matrix, situated on the point of intersection of these two lines of movement will be positioned over the type-casting mould.

The positioning mechanism for the carrying frame B2 of the matrix-case (not shown) is controlled from a rocking lever A24, which is mounted on the pivot A1". This mechanism is a duplicate of that above-described for the matrix-case.

According to the present invention each, or a selected number, of the gauging pins A may be used individually to determine, as already stated, two different positions of adjustment of the matrix-case. In the example illustrated the die-case is furnished with twenty-one rows ofrnatrices and by the present invention these twenty-one rows can be positioned selectively from the fifteen pins or a lesser number than fifteen In accordance with this invention, a supplementary jaw C is hinged on the jaw A3 so as `to project in front thereof (see Figs. 1, 2, 3 and 6). This jaw C is furnished on its forward face with three pin-engaging recesses C1 (see Figs. 2, 3, 4, 5 and 9) similarly to the jaw A3. The hinge between the jaws A3 `and C is conveniently formed by ,a rib C2 on the jaw C3 arranged to project into a channel in the underside of a hood a on the jaw A3. The rear end of the jaw rests on the top of the jaw A3. Thus the jaw C is moved backwards and forwards in company with the jaw A3, and in one position of yadjustment it is raised 'above the level of the gauge pins in their operative position (see Fig. 5) and any raised pin is then. engaged by the jaw A3. When the supplementary jaw C is lowered on its hinge in front of the jaw A3 (see Fig. 3) it can engage whichever pin of the series A is raised and the jaw A3 is thereby rendered inoperative. y

The supplementary jaw C is moved into and out of operative position under control of perforations or signals in the controlling record-strip in which case special signals accompany any character or like designating signals which control the gauging pins of the series A.

in order to render the movements of the jaw C responsive to the record-strip there is furnished on the said jaw a side lng C3 (see Figs. 4 and 6) arranged to move along a channel in a supporting bar D which is mounted on a shaft Dl at one side of the gauges A (see Figs. l and 2).

Connected Yto a projection D6 on the bar D is a rod of `a piston D2 situated in a cylinder D3 to which air is admitted at d from a conduit controlled by the recordstrip.Y When no air is admitted to the cylinder D3 the bar D remains in the position shown in Fig. 4 and the jaw C is in position to contact with the gauge pins A. A perforation in the record-strip for admitting air Vto the cylinder D3 will accompany the character designating perforations in the record-strip, which do not require the'jaw C to be in operative position. When i airis admitted. tothe cylinder D3 the piston D2 is raised and the jaw C is also raised clear of the pins A (see Fig. 6) by the raising of the bar B. When air pressure is removed from the piston D2 the bar D and jaw C are returned by a spring D4.

In the arrangement of the relative positions of the jaws A3 andY C, above described and shown in the annexed drawings, the first ten pins, counting from left to right, are used with the supplementary jaw C in operation, to bring the first ten columns of matrices inthe matrix case in line with the casting mould and the first eleven are used with the jaw A3 in operation, to bring the next eleven columns into alignment with the mould, thus providing twenty-one die-case positions from the fifteen gauge pins.

By a relative setting of the jaws A3 and C, the entire fifteen pins can be used with the jaw C for the first fifteen columns of matrices and the first or last six pins of the series can `be used with the jaw A3 for the extra six positions to provide twenty-one positions in all.

The arrangement, in all cases, will be that when the jaw C is in position to contact the last pin of the series A allotted toit, the jaw A3 will be one stage 'away from the first pin of the series A allotted to it.

The provision of the mechanism of the present invention does not interfere with the use on the machine of a die-case restricted to fifteen rows of matrices. When this use is desired, mechanism is provided for locking theV jawAC in lower or operative position and the jaw A3 will not be used. This mechanism comprises awedge piece E mounted on a slidable bar El (see Figs. 2, 4 and 8). Whenthe bar El is moved to the right from the position shown in Fig. 8 the wedge E passes under a. lug D5 on the bar D (see Figs. 4 and 6) and prevents the said bar D from being forced up by the controlling piston D2.

Likewise a pin yF (see Figs. l and 2) held in raised position by a spring (see Fig. 8) acts `as a stop for a rod B6 attached to the 'slide B4 which is coupled to the diecase. This` stopy prevents the over-throw or over-travel of the smaller sized die-case.

The Vwetige-carrying bar E1 and the stop pin F are controlled by hand. rl`he bar E1 is coupled to an arm G1 on a shaft G (see Figs. l, 2, 3, 4, 7, 8) on which are also mounted arms G2, G3, supporting a frame G4 which extends over the positioning mechanisms. When the frame is `moved by hand from the positions shown in full lines in Fig. 8 to that indicated by broken'ilines on the same figure, the pin F is withdrawn against the action of its spring b y an inclined face on a sliding bar F1 which acts against the pin F2 on the pin F. This sliding bar F1 is connected to an arm F3 mounted on the shaft F. At the same time the inclined piece E is moved under the lug D5 on the bar D. i

The nose of a die-,case having twenty-one rows is arranged to pass under the forward end of the frame G4 but the nose of a die-case containing only fifteen rows will be Vso arranged as to contact with the said frame. Thus, should the machine attendant neglect to set the frame to loclcthe jaw C operative position when a smaller rnatrixfcVaseY or master-plate is in use, then the die-case or master-plate in advancing, will shift the frame G4 and effect thelocling andl prevent accident or damage to parts O f th machine As previously stated, the mechanism of the present invention andthe existing gauging and positioning mechanism above described can also be applied to aphoto-typographical composing machine, wherein is employed a master ycharacter-pla"te in place of a matrix-case, for example, with the photo-typographical composing machine described and illustratedin the specification of U. S. A Letters Patent No. 2,388,961.

By means of this invention the primary positioning jawsrcanvdetermine or ydictate two different positions of adjustment for the matrix-carrier or the master-plate from any single pin of the primary gauges, thus providing for the employement of a considerable increase in the number of matrixes or characters that can be positioned from a given number of primary gauge pins.
