Title: Improvements relating to endorsing machines
IPC: B41K3/00
Filed: 1946-02-11
Abstract: 611,074. Endorsing machines. KODAK, Ltd. Feb. 11, 1946, No. 4238. Convention date, Jan. 25, 1945. [Class 100(ii)] A machine for endorsing cheques &c. is constructed so that means are provided for varying the positions of the printed or embossed endorsements on successive sheets of a series of similar sheets, either by automatically shifting the position of the printing &c. members or of the paper feeding members in a direction which is preferably transverse to the direction of feed. As shown, the sheets are fed along a flanged guide way 16 between guide plates 87, 89 and are fed between a platen member 85 and a printing or embossing member 25 mounted on a plunger 93 which is withdrawn from printing position by energization of an electro-magnet 96, and is moved by a spring 99 to make an impression upon de-energization of the magnet. An ink-ribbon may be passed between the sheet and the member 25. The platen 85 is mounted in a carriage 75 which is movable transversely to the direction of movement of the sheets, and the stamp 25 is also similarly movable. The transverse movements are effected by lead screws 81, 66 respectively. The carriage 24, in which the stamp 25 is mounted, is shown in Fig. 2, and it is formed with threaded apertures 64, 65 engaged by the lead screw 66 which is driven by gearing from a reversible motor 68 controlled by a switch 113 actuated by projections 30, 31 on the carriage 24. The sheets are fed through the machine by feed rollers 34, 35, 36, 37 mounted on the carriage 24 and driven constantly by a motor 61. Similar rollers are mounted in the carriage 75. After passing the rollers 35, 37 the printed sheet is guided for delivery between guide plates 88, 90. The carriage 24 is guided at the end opposite to that engaged by the screw 66 by means of rollers 63 mounted in an extension plate 33 and engaging opposite sides of a channel-shaped guide bar 62. The actuation of the electro-magnet 96 is controlled by feeler mechanism comprising a curved end 105 of a bell-crank 106 which projects through apertures 91, 92 in the guide plates and, when engaged by the sheet being fed, actuates a switch 100, 101 to close the circuit of the magnet coil 96. The switch is automatically opened by the action of a post 111 on the printing-stamp which acts upon the trigger mechanism associated with the bellcrank 106.

Title: Improvements in or relating to optical measuring systems
Inventor: MERTON THOMAS RALPH
IPC: G01B21/06
Filed: 1955-02-14
Abstract: 822,543. Photo-electric measuring apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 14, 1956 [Feb. 14, 1955], No. 4367/55. Class 40 (3). An optical measuring system of the kind in which a distance is determined by counting the number of (moisÚe) " fringes " which pass a given point when one line grating is moved with respect to a further grating over the distance to be determined comprises a first grating G (Fig. 1), movable with respect to a spaced plurality of further gratings g1...g6, each of which has associated therewith a light source l and a photo-electric cell p (which feeds the " fringe " counting device) and the spacing of which is such that grating G " overlaps" any two adjacent ones of the further gratings as it moves between the left and right-hand extremes. This arrangement allows extended distances to be determined without the need for line gratings of comparable lengths. Fig. 8 shows a practical realization of the system and comprises a base member 11 on which the grating G (the lines on which extend in the vertical direction) is movably mounted by means of a slidable carriage 13, the base member also carrying the plurality of further gratings (the lines on which also extend in the vertical direction) and associated light sources and photo-electric cells one combination of which is shown at g1, l1 and p<1> respectively. To effect the initial setting-up adjustment of the apparatus the direction of the lines of the gratings g<1> .. , g6 are first given a slight inclination with respect to the lines of grating G (in order to allow the production of " fringes ") by means of a worm 24 and worm wheel 25 (controlled by a knob 26) which effects a rotation of the member 17 (carrying grating gl and photo-electric cell p1) with respect to a bracket 17 attached to base 11. The width of a horizontal slit 23 across which the fringes (comprising horizontal bands alternately light and dark) move vertically as grating G is moved, is next adjusted to allow transmission of a single band only and when this adjustment has been completed for each of the assemblies carrying the gratings g1 ... g6 the position of each slit 23 in the vertical direction is then adjusted so that when grating G is moved past positions in which its ends " overlap " any two adjacent ones of the gratings g1 ... g6 the pulses generated by the photo-electric cells associated with latter gratings occur simultaneously. With this adjustment made a count of the pulses produced in each photo-electric cell by the passage of the " fringes " across the slits 23 is then truely representative of the distance traversed by grating G, the output of the cells being supplied to a counting device for this purpose and the carriage 13 being provided with contact making and breaking devices by means of which the various cells may be switched out of circuit when grating G has passed the grating g1 ... g6 appropriate to that cell.

Title: Improvements in and relating to apparatus for joining pieces of yarn
IPC: B65H69/06
Filed: 1941-04-07
Abstract: 548,423. Piecing or splicing yarns. COOK & CO., MANCHESTER, Ltd., and CHARNOCK, C. J. April 7, 1941. No. 4592. [Class 120 (iii)] Apparatus for piecing yarns comprises two opposed yarn-retaining devices 16, Fig. 1, mounted on a common supporting means and actuated by a single mechanism to untwist the respective pieces of yarn held by them and after pulling off the loose ends to bring the remaining yarn ends together and to rotate and twist them in the reverse direction and thus unite the two pieces. The yam ends to be united are arranged in a channel 48, Fig. 11, on a table 33 and are secured by retaining springs 17 in the axiallyaligned slotted spindles 16 and by breaking means 47, 47a. Each spindle 16 is rotated by a pinion 18 from a train of gear wheels 19 driven e.g. by a handle from a common shaft 20 through a differential gear comprising pinions 22, 23 and a free bevel pinion 24 mounted on a block 25 on the shaft 20. The pinion 23 is integral with a pinion 27 while the pinion 22 is mounted on a sleeve carrying a bevel pinion 28 which engages a pinion 29 on a vertical shaft carrying the table 33 and yam breaking mechanism 34. A twist adjustment drum 35 is also provided consisting of two parts one mounted on the shaft 20 and the other rotatably adjustable thereon and secured by a nip screw. Arms 37, 38 project from the two parts of the drum 35 the former co-operating with a stop 39 fixed about the shaft 20 and the latter with an arm pivoted on'a support 40 and having a retaining notch 42 held up by a spring 43 to engage an arm 44. When the handle is rotated the drive is from the gearing 27, 23 and through the bevel 24 as the pinion 22 is held by the arm 44 engaging the catch 42. The shaft 20 rotates however and brings the arm 39 against the. stop 37 which turns the drum 35 and when the pin 38 depresses the pivoted arm the arm 44 and the bevels 22 and 28 are freed and the drive passes thence to the pinion 29 and the wheel 30 and pinions 31. In use the yarns passing through the hollow spindle 16 are laid parallel in the channel 48 and nipped at 47, 47a and the handle is then rotated to untwist the lengths held between the members 17, 47. When the appropriate number of turns have been removed according to the setting of the drum 35 the pin 38 releases the catch 42 and the pinions 31 are rotated thus swinging the horizontal arms 45 and breaking the ends nipped at 47. When the arms 45 reach the end of the outward movement a peg operates to stop the handle and when released the parts are returned to their original positions by spring mechanism the yarn ends in the channel 48 being rotated sufficiently quickly to engage one another and form an even splice. Alternatively the reverse rotation may be obtained by positive rotation of the handle.
