Title: Improvements in Devices for Reading Perforated Tapes and the Like.
Inventor: MARLOW RICHARD ZBIGNIEW
IPC: G06K7/04
Filed: 1967-10-25
Abstract: 1,165,596. Sensing records. CREED & CO. Ltd. 25 Oct., 1967, No. 48465/67. Heading G4M. A perforated tape or card 3 is sensed by elements 5 biased towards the record 3 by springs 4 and moved parallel to the feed path simultaneously with a reciprocable feed member 7, and each element 5 operates an associated switch 28 during the feed stroke, the reaction on each element 5 of the force necessary to operate the associated switch 28 passing through the pivot 2 of the element. The armature 9 of a magnet 12 acts on the common pivot shaft 2 of the sensing elements 5 and feed member 7 to move the elements 5 and member 7 in the feed direction, a sprung detent member 13 being temporarily cammed out of the feed path by movement of record 3. An element 5 which has engaged a code perforation is in the position shown, and during the feed stroke its surface 6 engages surface 18 of a slider 19 to close contacts 27, 32, slider 19 being held in the position shown during the return stroke by latch 23. If, during the next feed stroke, the element 5 senses a " space ", it will be pivoted anti-clockwise and its surface 17 will release latch 23 to allow slider 19 to move to the right under the action of spring 24, thereby closing contacts 29, 32. The recordengaging extensions of elements 5 and member 7 have a non-linear sloping rear surface to impart initial downward momentum thereto as they are cammed out of engagement with the record during the return stroke. The feed member may operate a similar switch 28 to indicate presence or absence of tape in the reader.

Abstract: 978,108. Lubricating. HERR MANUFACTURING CO. Inc. Dec. 9, 1963, No. 48488/63. Heading F2A. [Also in Division D1] So that the level of lubricant in a reservoir of a spinning-ring holder can readily be ascertained, an indicator 12 is provided in the cover of the reservoir of which the lower part is of prismatic form with an inclined face 21 terminating short of the bottom of the reservoir, so that the point at which this face intersects the surface of the lubricant indicates the level of the lubricant. The indicator is a friction-fit in a cover 8 which rests on a shoulder 9 and in a groove 10 in the holder. It is of transparent material and has a convex, magnifying top 15 providing a flange 16 resting on the cover. It has a cylindrical part 14 above the prism, so that when the level is seen to be at the top of the face 21, there is still room for more oil, thus reducing the risk of overfilling; also, as the face stops short of the bottom of the reservoir, when the level is at the bottom of the face there is a reserve of lubricant in the reservoir. A filling port with a resilient cover having a filling aperture 28 and upper and lower concavities is also provided. There is a vent in the cover.

Abstract: 992,286. Shearing. JOSEPH RHODES & SONS Ltd. Dec. 16, 1963 [Dec. 27, 1962], No. 48639/62. Heading B3W. A method of operating hold-downs for clamping plates in a shearing machine, consists in applying fluid pressure to move the hold-downs initially into contact with or close proximity to the plate and then applying a different fluid pressure to effect a clamping pressure. Each hold-down 1, Fig. 1, comprises a body 2, having ports 4 by which the hold-downs are connected in series in an hydraulic line, and containing a piston 6. At the lower end of the piston is a flange 8 and clamping foot 9, and the central portion of the piston passes through an annular chamber 10 to which hydraulic fluid is admitted to retract the hold-downs. The body also forms two air cylinders 13 in which are pistons 14 which are mounted on the flange 8. In an alternative arrangement, standard hydraulically operated hold-downs are used and an airhydraulic slow approach unit is connected in the hydraulic supply lines to the hold-downs. This slow approach unit, Fig. 5, comprises an hydraulic cylinder 37 containing a piston 38 and an air cylinder 42 containing a piston 41. The cylinder 42 has a connection for an air line 44 and has an air bleed hole 45. When the machine is operated by a treadle 17, Fig. 3, air from a charge cylinder 51 passes to the pilot cylinder of a valve 54 and moves this valve to admit air through an adjustable throttle valve 56 to the cylinders 14 of the hold-downs 1, or to the cylinder 42 of the slow approach unit, Fig. 4, causing the piston 38 to displace the oil above it into the standard type of hold-down 1a. At the same time air flows into a charge cylinder 60, and when the pressure in this cylinder reaches a predetermined amount a valve 61 is operated and allows air to pass through a pilot line 62 to reverse the valve 54 and exhaust the air from the cylinders 14 or the cylinder 42. Pilot air from the leak-off port 65-of valve 54 passes to a valve 48 which is operated to admit air to the cylinder containing a piston 49 which operates mechanically an hydraulic valve controlling the operation of the machine. At the end of the machine stroke air is automatically admitted to the other side of the piston 49 which operates the hydraulic valve controlling the machine to raise the hold-downs hydraulically.

To preset a tuning position a pushbutton 41 is pulled out (Fig. 3, not shown) so that a cam 38 releases clamping levers 34, 35 to enable pivoting of a follower plate 33. A spring 24 causes a roller 17 to engage a disc 16. By rotation of a tuning knob 23 a bar 12 and link 13 are moved to the required tuning position via gears 21, 22, rollers 19 and 17 and disc 16. This causes semi-circular fork members 28 to be rocked about pins 29, 30 to the corresponding tuning position. Now when the push-button 41 is pushed in first the follower plate 33 is rotated to the position determined by the fork member 28 and then the cam 38 engages clamping levers 34, 35 to lock the plate 33 in position. When this preset button 41 is pressed in a pin 42 on the slide 31 of the button engages a nylon thread or steel wire 43 which pulls the roller 17 out of drive with the disc 16 and enables the bar 12 to be positioned by the preset follower plate 33 engaging the associated fork member 28. The mechanical actuator may be used to control a mechanical, pneumatic or electrical device.
