Title: Improvements in and relating to flat bar knitting machines
IPC: D04B11/22
Filed: 1934-10-09
Abstract: 432,665. Knitting-machines. SCHUBERT & SALZER MASCHINENFABRIK AKT.-GES., 11, Lothrinagerstrasse, Chemnitz, Germany. Oct. 9, 1934, No. 28916. Convention date, Oct. 14, 1933. [Class 74 (ii)] Lace patterns and tuck patterns are produced in a straight bar machine with the aid of auxiliary instruments 2, 3 respectively that are slidably mounted in a frame 1 and are actuated by draw bits 8 controlled by a Jacquard including hooks 13 and an oscillating blade 15. When tuck stitches are required the appropriate instruments are lowered from their normal position, in which they act as pressers for producing ordinary loops or stitches, to permit the yarn to enter the hooks. In lace patterning the support 1 is raised and the auxiliary instruments 2 that have not been lowered engage the lace points 25 to prevent transfer of loops. The instruments 2, 3 may be actuated by a common element operated by a draw bit or a single instrument having a presser head on one side and a groove on the other may be used. Specification 310,928, [Class 74 (ii)], is referred to.

Title: Improvements in or relating to two-speed hubs
IPC: B62M11/14
Filed: 1962-07-27
Abstract: 959,351. Change speed epicyclic gear. FICHTEL & SACHS A.G. July 27, 1962 [Aug. 2, 1961], No. 29044/62. Heading F2D. [Also in Division B7] In a back-pedal gearshift two-speed bicycle hub providing direct and overdrive as shown, or direct and reduced (Fig. 4, not shown), and comprising planets 17 on an input (or free) carrier 2 meshing a free (or input) ring 13 and a fixed sun 18, a sliding clutch sleeve 4, constantly engaging by arms in slots or teeth 5, the inner member 6 of one-way cam and roller, or pawl-and-ratchet output drive means, is selectively engageable with the ring 13 for overdrive (or direct drive) and the carrier 2 for direct (or reduced) drive. As shown, a body 8, rotated by the inner member 6, carries drive pawls engageable with the ratchet teeth 11 in the hub shell 12. A control member 20, rotatable on, and abutting, the clutch sleeve 4, has facial cam teeth 21 co-operating with cam teeth 23 on the ring comprising deep and shallow notches 22, 27. In Fig. 7 (not shown), the cam teeth may be rounded. The control member 20 and the body 8 are respectively held from reverse rotation by friction springs 25, 26. In the direct drive position the overdriven ring deep notches 22 engage the control member teeth 21. For shift, back-pedalling effects reverse rotation of the ring relative to the detained control member which, together with the clutch sleeve 4, is thereby leftwardly cammed by the cam surfaces of the teeth 21, 23 against a spring 28 until the teeth 21 engage the shallow notches 27 and the clutch sleeve 4 engages the ring 13 for overdrive. On further backpedalling the control member teeth 21 move relatively along the ring teeth 23 until they re-engage the ring deep notches 22 for direct drive. As shown, the body 8, in axial or radial cam or screw-threaded engagement with the inner member 6, has a conical portion engageable with a brake shell 14 expansible into engagement with the hub shell 12. Alternatively, a plate brake may replace the shell 14. when the bicycle wheel and hub shell are rotated backwards, the one-way output drive means releases the brake and prevents application thereof. The body 8 acts as a shift-limiting means. In Fig. 3 (not shown) dispensing with the brake, the body 8 is extended so as to be screwed into engagement with the adjacent bearing support and thereby limit shifts to one change.

Title: Improvements in conveying equipment
IPC: B65G47/48
Filed: 1956-09-26
Abstract: 820,303. Endless conveyers. VALIDA MASKINER A.B. Sept. 26, 1956 [March 1, 1956], No. 29363/56. Class 78 (1). In conveying equipment comprising an endless conveying element 1 on which objects, e.g. work containers 5, are carried, the objects are discharged automatically at one of a number of stations by means including a pivoted pusher 6 at each station, the pusher being operated through linkage by means including a runner 13 which is longitudinally slidable along a pair of rods 14 and carries a pivoted element 10 adapted to be projected from an inoperative position to a position in which it is engaged by the conveying element by means controlled by the setting of selector means on the object. The conveying element 1 is as described in Specification 820,304 and comprises a series of blocks travelling in a guideway formed by bent-over portions 2 of plates 4 and a base-plate 3 of inverted channel-section. The containers 5 rest centrally on the blocks, being located by longitudinal ribs on their undersides engaging the sides of the blocks. Further ribs at their outer edges are provided for engagement with the plates 4 should the containers tilt. The selector means comprise on the forward end of each container a transverse rod 35, Fig. 5, provided with a number of locating grooves for a pair of selector dogs 33 slidable along it, each dog 33 having a spring-loaded ball for engagement with the grooves. At each discharge station a pair of arms 32 is provided at characteristic positions along separate rods 29 for engagement by the dogs of a container set for discharge at that particular station Upon such engagement both rods 29 are rotated against the action of counterweights to cause arms 28 at their inner ends to bear against opposite sides of a triangular plate 27 centrally pivoted on a pin projecting outwardly from a shaft 25. By this arrangement the shaft 25 is rotated only when both arms 32 are engaged by dogs 33. Rotation of shaft 25 causes a pin 11 to be raised into contact with the element 10 whereby the element 10 is caused to pivot from its retracted position in which it is held by gravity into an oppositely tilted position in which it is also held by gravity and in which it lies in the path of the block carrying the container. The runner 13 is now engaged by the advancing block and pushed along the rods 14 until it reaches a release cam which returns the element 10 to retracted position. The movement of runner 13 is transmitted by a link 16, a two-armed lever 18, 20 pivoted at 19 and a link 22 to the pusher 6 causing a head 8 and shoulder 9 of the pusher to engage respectively the side and bottom of the container at one side, lift the container off the conveying element and push it laterally over the plate 4 at the opposite side on to a receiving table.
