Title: Mechanical movement for a measuring instrument
IPC: G01P5/14
Filed: 1945-09-27
Abstract: 621,614. Indicating-apparatus. WEINGART, R. I. N. Sept. 27, 1945, No. 25065. Convention date, Dec. 13, 1944. [Class 106 (iv)] [Also in Group XXIV] Mechanism for converting rotary movement about one axis into rotary movement about another axis at right-angles, is described in connection with a pressure-responsive instrument, and comprises a cam member 33, Figs. 1 and 3, having a driving edge 35 of an increasing radius which is rotated about a spindle 26 by a connecting link 56 from the pressure-responsive device 50. The edge 35 of this cam co-operates with a spiral groove 22 in a cylindrical member 21 on a shaft 13, 20, the axis of which is disposed in a plane parallel to the plane of the cam 33. Thus rotary movement of the cam 33 converts the linear movement derived from the pressureresponsive device 50 into a rotary movement of shaft 20, which latter carries a pointer 46 to indicate the amount of movement and the degree of pressure acting on the device 50. The lead of the spiral groove 22 may be non- uniform and the contour of the cam 33 varied as required, providing jamming does not occur in the groove. The point at which the link 65 is connected To the cam can be adjusted by means of a slotted link 59 through which the shaft 26 of the cam passes and which is clamped to the cam by a screw 61. The thrust on the cylindrical grooved member 21 is taken by the lower bearing of its spindle 13 and a helical spring 47 is provided to maintain the thrust on this bearing and effect return movement of the mechanism. In a modified arrangement the end thrust on member 21 is taken by a further edge on the cam 33, which may or may not be circular, engaging a conical end on the member 21. Thus the additional thrust edge may modify the rotation imparted to the pointer. In Fig. 8, the driving cam is formed by a strip of metal 79 secured at one end to an arm 78 which may be varied in contour to give the desired movement. In this arrangement also a screw 83 is provided for zero adjustment of the pointer 46 and the shaft 27 of the arm 78 can be adjusted in a slot 82 to further vary the movement transmitted. Specification 557,639 is referred to.

Patent GB-534637-A (GB)
Title: Improvements in or relating to safety guards for presses suitable for use in performing cutting out operations
IPC: F16P3/04
Filed: 1939-09-08
Abstract: 534,637. Machinery guards. BRITISH UNITED SHOE MACHINERY CO., Ltd., and BAGSHAW. C. M. Sept. 8, 1939, No. 25383. [Class 80 (iv)] In a cutting-out press a framework 1 has a pair of slides for a horizontal table 5 provided with handles 19. Below the table is a shaft 7 rotatable by a pulley 9 and carrying at its other end a pinion meshing with a large gear wheel 11 keyed to a shaft 13 carrying eccentrics the straps of which actuate pairs of rods 15 to which a pressure-applying .beam 17 is adjustably secured. The table 5 is adapted to support a fibre cutting-block upon which the material and a cutter are placed. A guard 21 in the form of a rectangular frame with cross wires is secured to the forward ends of two arms 25 pivoted at 27 to brackets 29 secured to the framework 1. The arms 25 are connected by rods 31, 33. The guard falls normally by its weight into the operative position, its downward movement being limited by stops 35, 37, and it is raised by power. For this purpose, a catch-piece 39 on a rod 15 is adapted to engage a pawl 41 pivoted on the left-hand arm 25. The pawl is normally held away from the piece 39 by a spring 43. The pawl is moved into the path of the piece 39 by a bell-crank lever 45 pivoted to the bracket 29 and carrying a roller 46. The other arm of the lever has connected thereto a Bowden wire 47 the other end of which is connected to a second bell-crank lever 49 pivoted on a bracket 51 secured to the framework 1. The lever 49 is arranged to be rocked by a bar 63 extending transversely of the machine and connected by pin-and-slot connections to slides 55, 57 in the handles 19. If both slides are moved forwardly the bar 53 will be moved sufficiently to rock the levers 49 and 45 and to move the pawl 41 into the path of the catch-piece 39 and so raise the guard. If, however, only one hand be used and one slide moved by the operator the bar 53 will merely pivot about the other slide and the guard will not be raised. To hold the guard in raised position when the operator is holding both slides, a small latch 61 is pivoted on the lefthand arm 25 and its rearward movement is limited by a pin 63 on the pawl 41. When the pawl 41 is moved rearwardly by the bell-crank 45, the latch will move into contact with a catch-plate 65 on the bracket 29 thus preventing downward movement of the guard. If the operator relaxes his grip on one of the handgrips, the pin 63 will engage the latch 61, move it forwardly and allow the guard to fall. According to the Provisional Specification, the guard slides in vertical guideways and may be adjusted heightwise by a series of holes to receive bolts, the downward movement of the guard being controlled by a spring. To raise the guard, a catch-piece on one of the vertical rods is arranged at times to strike against the enlarged lower and free end of a pendulous lever.

Title: Improvements connected with the injection moulding of small articles
IPC: B29C45/38
Filed: 1946-08-27
Abstract: 644,354. Injection-moulding of small articles. MAZZONI, L. Aug. 27, 1946, No. 25640. Convention date, June 24, 1943. [Class 87 (ii)] Beads, thin plates, buttons, &c. are made by injecting moulding material through channels 9, Fig. 3, formed in superposed mould parts 5, 6, 7 to cavities 1 formed in opposite faces of two parts 4, 5, the cavities 1 being so shaped as to form a depression in one or both sides of each moulded article and the channel outlets being of small diameter and located at points in the cavities corresponding to the bottoms of the depressions in the moulded articles. After solidification of the material in the cavities and injection channels, the upper part 7, Fig. 4, of the mould is raised, then the part 6, Fig. 5, is raised, carrying the sprues 10 with it to fracture the connection of the sprues to the moulded articles, and finally the parts 4, 5 are separated to release the articles. The parts 4-7, Fig. 8, are held between upper and lower pressureplates 12, 11, the upper part 7 carrying the injection orifice 14 leading to the channels 9. The mechanism for opening the mould comprises a tubular push-rod 16 rigidly connected to a plate 17 located in a chamber 18 in the lower plate 11, the plate 17 carrying four pushrods 19 fixed to the part 6. The rods 19 pass freely through sockets 20 in the part 5, the sockets being freely slidable in the part 4, and shoulders 21 on the rods 19 abut against recesses in the sockets 20 when the rods 19 are raised, this moving the part 5. The tubular push-rod 16 is traversed by a push-rod 22 secured to a plate 23 carrying rods 24 which pass through the parts 4, 5, 6 and form rejectors for the sprues in the part 6. A strong spring 25 tends to retain the push-rods 16, 22 in the extended position whilst springs 26 on the pushrods 19 tend to raise the part 6 with respect to the part 5. On opening the part 7, the spring 25 retains the plates 17, 23 at the bottom of the chamber 18 against the action of the springs 26 which tend to raise the part 6 with the pushrods 19. The push-rod 22 is then progressively raised carrying with it the plate 23 and rods 24 and permitting the plate 17 to rise under the action of the springs 26 taking with them the part 6 which raises with it the sprues which are torn from the moulded articles. The part 6 ceases to rise when the shoulders 21 abut against the sockets 20 and then the rods 24 continuing their upward movement effect the sprues. As the upward movement of the rod 22 continues, the tubular rod 16 is eventually carried with it and the plate 17 then resumes its upward movement raising the rods 19 which by means of the sockets 20 raise the part 5 and permit the moulded articles to be removed. The beads &c. may be moulded on a cord or braid or on a series of parallel cords to form a pseudo-fabric, the mould having grooves to accommodate the cord &c. Beads may be moulded in successive lots on braid, the braid being advanced to a new moulding position after the moulding of one lot of beads.
