Title: Manually Operated Printing Machine
IPC: B41L45/02
Filed: 1966-10-21
Abstract: 1,157,819. Addressing machine; stencil printer. DYMO INDUSTRIES Inc. 21 Oct., 1966 [22 Oct., 1965], No. 47386/66. Headings B6C and B6D. A manually - operated stencil - printer, especially an addressing machine of the type in which a print roller receiving ink from an inking roller traverses a stencil forcing the ink therethrough on to a workpiece, is provided with a device which prevents the print roller from traversing the stencil until the latter is correctly positioned and bearing upon the workpiece with a predetermined force. General arrangement.-Fig. 3 is a side elevation of the machine in which the base 12 supports a platen 16 for receiving a workpiece 38, e.g. a card or envelope. A track assembly 18 is mounted for movement towards and away from the base in response to movement of operator lever 20 which comprises two parallel arms 46 linked by a handle 22 and pivoting on a fulcrum provided by cam rollers 48. The track assembly 18 carries two hoppers (24), 26 (Figs. 1, 2, not shown); a stack of stencils 28 are located in the feed hopper (24), pushed manually in turn under the printing station, and then received by hopper 26. Printing operation and mechacism.-A downwards push on lever 20 brings track assembly 18 carrying stencil 28 against workpiece 38, and the housing 120 encloses a fulcrum bracket 54 (Fig. 5) carrying the printing mechanism, the track 18 and the hoppers (24), 26; thus bracket 54 pivots about fixed pin 56 under the action of the operator lever 20 through pin 62 and is biased away from the platen 16 by return springs 67. Print roller 64 is journalled between links 70 pivoted at 72 to the bracket 54, and compression springs 78 bias the roller towards the position shown in Fig. 5. Upon application of the downward force on handle 22 of operator lever 20, pin 62 is raised and bracket 54 forces the print roller 66 against the workpiece 38 on the platen 16. Continued downward movement of handle 22 forces the fulcrum bracket 54 to rotate still further, making the roller 66 traverse the stencil 28, the angle of the links being such that the roller does not traverse until sufficient force for satisfactory printing has been built up. Inking apparatus (Fig. 4).-Inking roller 86 is also journalled between the links 70 and is urged into contact with print roller 66 by springs 89. Means are supplied for positively rotating the inking roller 89 during the return movement of links 70 after each addressing operation. Ink supply.-A cylindrical reservoir 100 is journalled on bracket 102 pivoted to the fulcrum bracket 54, and normally biased out of contact with inking roller 86. When required, the bracket 102 is normally pivoted, and the roller 81 is rotated by turning knob 108, ink passing through perforations 110 on to the surface of the inking roller.

Abstract: 1,117,809. Cathode-ray tube displays. INTERNATIONAL BUSINESS MACHINES CORPORATION. 28 Oct., 1966 [1 Nov., 1965], No. 48335/66. Heading H4T. In an arrangement in which characters are traced on the screen of a cathode-ray display tube by deflecting the beam between coordinate address points in a matrix, signals determining each character are translated into a plurality of sets of coded signals each set of which determines address points in a respective different size of matrix, all matrices being symmetrical about a common centre position. The invention is described in connection with a system in which a main deflection yoke 14, 16 (Fig. 1) is utilized to trace curves such as 150, 152, (Fig. 4) whilst an auxiliary deflection yoke 18, 20 is utilized to display, on such curves, symbols such as 158, 160, 162, 164, 166, it being required that the symbols, particularly when they indicate the positions of data from which the curves are drawn, be centred on the curve and that this location remain fixed if the symbols are changed in size as indicated at 168, 170. To this end the central processor unit or computer 10, which supplies signals controlling the curve tracing to digital-to-analog (D/A) converters 30, 32 and signals determining the character symbols to a character generator 42, also provides a beam blanking control signal on line 60, signals comprising a two-bit binary code indicative of three different sizes of characters on lines 70, 72 and a signal CM indicative of the non-character tracing mode on line 68. The latter signals are fed to translators 44, 46 (detailed in Fig. 2, not shown) which, during the non-character tracing mode (i.e. during the tracing of curves by yoke 14, 16), supply yoke 18, 20 via D/A converters 34, 36 with a " Home Position " signal specified by a 32 bit binary code and defining a common centre point for each of three different sizes of matrices A, B, C (Fig. 3). In the character tracing mode the matrix origins OA, OB, OC are then specified with respect to this centre point from which the character symbols are traced under the control of a three bit binary code from the character generator 42 which is converted by the translators to a code appropriate to the particular matrix.

The assembly 1 Fig. 2 includes an axially slidable sleeve 9 supported within a fixed bracket 8 and carrying an abutment 36 which is contacted by the bar during feeding. Axial movement of the sleeve is limited in both directions by an adjustable nut 17 whose upward extension 16 moves in a fixed slot 15, and a spring-biased pad 11 serves to brake movement of the sleeve. A cam roller 27 is carried by a downward extension of the nut and cooperates with a cam 32 attached to the roll 5.  In operation, the bar M pushes the sleeve to the left which causes the upward extension 16 to trip a switch 31 for starting rotation of the rolls. The switch provides an electrical indication that the stack has been fed in. When a complete rotation of the rolls has been made (and the bar has been profiled by the tools) the cam 32 moves the nut 17 back to its initial position.

Abstract: 1,038,890. Feeding sheets. LINOTYPE & MACHINERY Ltd. Dec. 17, 1964 [Dec. 20, 1963], No. 50526/63. Heading B6B. In a machine as described in Specification 926,193 wherein sheets are fed by gripper bars 12, Fig. 1 (not shown), on endless chains 13 between platens 26, 27 which move towards each other to operate on the sheet and at the same time move forward with the sheet, the gripper-bars 12 are movable within limits relatively to the chains 13 by means associated with one of the platens to register the sheet. The chains 13 have a cyclical movement so as to move slowly when receiving a sheet from a pile 10, then accelerate to feed a sheet between the platens, and decelerate as the platens close on the sheet, and in one form are moving slightly faster than the forward movement of the platens at the time the platens engage the sheet. Each gripper bar 12 has a lug 32, Fig. 2b, at each end fixed to a pin 31 slidable in a U-shaped bracket 29 fixed to a chain 13. A spring 33 biases the bar 12 in the direction of feed. On one of the platens is pivoted arms 34 held by springs 35 against stops 36 on the platen. The ends of the arms 34 lie in the path of the bars 12 as the platens close, and the springs 35 are stronger than the springs 33, so that when a bar 12 is engaged by the arms 34 it is moved rearwardly to register the sheet carried thereby. When the platens begin to move apart, the arms 34 engage fixed stops 38 or may be operated by solenoids which cause them to move out of the path of the gripper bars. If the chains move more slowly than the forward speed of the platens, the arms 34 are arranged to engage behind the bars 12 and move them forward relatively to the chains 13 for registering the sheet. The machine may be a printing, embossing, or cutting and creasing machine and the registering mechanism described may also be used at a waste-stripping station.
