Title: Improvements in or relating to stop-motions for textile machines
Inventor: FEATHER EDMUND ERIC
IPC: D01H13/18
Filed: 1953-03-02
Abstract: 724,689. Stop-motions. PRINCE-SMITH & STELLS, Ltd. March 2, 1953, No. 5732/53. Class 120 (2).  A textile machine having a stop motion of the kind comprising a feeler that is biased to tend to move from one side to the other across the run of stock but is normally precluded by the presence of stock under tension from moving to the said other side is characterized in that the feeler is repetitively or cyclically first so actuated and retained against its bias by a continuously driven part of the machine as to be clear of the run of stock and then released to permit movement under its bias towards and (in the absence of stock under tension) beyond the run of stock. As shown a feeler 24 is pivoted about a non-vertical axis by an arbor 25 carried in a bracket 26 and has attached thereto a striker plate 27 of V-shape. A striker 29, mounted for oscillation on a shaft 30 and oscillated by means of the crank 31 with a roller 32 at its end and the roller 33 at the end of a crank 34 keyed to shaft 35 which may be rotating continuously or rocking, periodically, contacts the surface 28 of the striker plate 27 and thus oscillates the feeler 24 into and out of its stock feeling position shown in chain-dotted lines in Fig. 3. Should the stock be absent when the feeler 24 tries to contact it the feeler swings over beyond the position shown in Fig. 3 and the striker 29 on its next movement contacts the other side 37 of the plate 27 and forces the feeler over to the position shown in Fig. 4. The feeler 24 has a rearward extension 38 provided with an adjustable tappet screw 39 which co-operates with a lever 40 mounted on a pivoted crank member 41. Actuation of this crank member through movement of the lever 40 rotates the latch member 21 about its pivot 22 and thus disengages the latch from under the blade or hammer 20 which falls under the action of gravity and clamps the stock 16 against the anvil 23. The movement of lever 40 may be used to initiate any other desired operation or change of operation of the machine. In a second embodiment cam means are used for controlling the movement of the feeler 24. Specification 720,751 is referred to.

Title: Latex foam vulcanizer
Filed: 1940-03-30
Abstract: 535,510. Presses for moulding sponge rubber articles. BRIDGE & CO., Ltd., D. March 30, 1940, No. 5762. Convention date, July 29, 1939. [Class 87 (ii)] A press for moulding sponge rubber articles such as seat cushions comprises three portions, a base portion 16, an intermediate portion 17 and a top portion 18 forming a cover, the portions being movable into superposed registry with each other to form a closed chamber 21 and carrying mould sections 29, 30 adapted to be in mating relation when the press is closed. Steam is introduced into the closed chamber 21 to act as a heating medium for the moulds. The top and intermediate portions are moved in stepped relation upwardly and rearwardly automatically on completion of the vulcanization, the top portion being also tilted so that the mould sections 29 can be readily emptied and refilled. The portions 17, 18 are raised and lowered by the action of a motor 95 acting through a shaft 92 and levers 91 and 88, which rotate the pivoted levers 74 and 68 which are connected by a link 84. The intermediate portion 17 is maintained horizontal while opening by a roller 99 travelling in a guide 98 and links 114, 107 and 113, and the top portion 18 is tilted by a guide 101 thereon and a roller 102 fixed to 17. When the mould sections 29 have been filled the operator presses a switch which starts the motor 95 and closes the press. The motor is stopped by a cam switch and a valve is opened automatically to admit steam to the chamber 21, a timer circuit being also started to control the period of vulcanization, and the steam pressure operates a safety device which prevents opening of the press while steam pressure exists. On completion of vulcanization, the steam valve is closed and another valve is opened to exhaust the steam by suction, the safety device is released and the motor is started to re-open the press. The mould sections 30 are held in place by catches 36, on release of which the sections can be swung out for cleaning and are so mounted as to permit adjustments for varying sizes. Adjustable screws 117 limit the rearward swing of the cover portion 18 and compression springs 120 prevent jerking movement.

Title: Improvements in hydraulic pumps
IPC: F04B23/10
Filed: 1962-02-15
Abstract: 927,325. Reciprocating pumps. W. A. WHITNEY MANUFACTURING CO. Feb. 15, 1962 [April 6, 1961], No. 5905/62. Class 102(1). In a pump for alternately supplying two utility points, e.g. a double acting motor for a machine tool, a cylindrical casing 23, Fig. 1, housing a reversible gear pump unit feeding a swash plate pump unit is rotatably mounted in a housing 13, the arrangement being such that reversing of the direction of rotation of the gear pump causes the casing to turn thereby aligning an outlet 53 in the end of the casing with one of two apertures 57, 58 in the housing leading to the utility points. A reversible electric motor 15 drives gear pump 25, 30 and swash plate 37 through shafts 17, 18. Movement of casing 23 is limited by a pin 72 in an arcuate slot 73. Liquid is drawn from a housing reservoir 33 via a filter 32. A spring-loaded sleeve 89 in outlet 53 provides a seal between the casing and the housing. An arrangement of check valves in the gear pump supply and delivery lines, Fig. 5, ensures unidirectional flow in either direction of rotation of the gear pump. An unloading valve 50 by passes the gear pump output to the reservoir when the required feed pressure is exceeded. The aperture 57, 58 not aligned with outlet 53 serves to return liquid from the utility points to the reservoir via a groove 87, 88. High pressure relief valves 80 are provided in the two outlet conduits. Check valves control the inlet and outlet of each cylinder of the swash plate pump unit. The assembly is readily dismantled and is portable by a handle 14.

Abstract: 525,505. Magnetos. BENDIX AVIATION CORPORATION. Feb. 22, 1939, No. 5947. Convention date, Feb. 26, 1938. [Class 35] The rotor of a magneto supplying two simultaneous sparks comprises arcuate magnets 11 separated by pole-pieces 12, 13 of unequal lengths and the stator comprises pole-shoes 21, 22 having their adjacent ends unequally spaced and two coils 27, 28 the cores 25, 26 of which are mounted on the ends of the stator pole-pieces. As shown, the rotor magnets are retained with the pole-pieces 12, 13 between non- magnetic plates, 14, 15. Tapped holes 19 are provided in the plate 14 to facilitate withdrawal of the rotor. The primaries of the armature coils 27, 28 are in series and the secondaries separately connected to spark plugs, whereby two simultaneous sparks are produced. When used with a two cycle twin cylinder engine, generation of one of the two sparks normally produced per revolution of the rotor is avoided through the unequal lengths of the rotor pole-pieces and the unequal spacing of the stator pole tips. The interrupter cam is formed on the hub 6 of a detachable fly-wheel 5 and a single contactbreaker 8 and a cam-lubricating device 35 are mounted within the cupped rim of the wheel. The magneto casing is adjustable about the rotor axis.

Abstract: 563,099. Repeater systems. WESTERN ELECTRIC CO., Inc. April 16, 1943, No. 6136. Convention date, April 18, 1942. [Class 40 (iv)] The gain-frequency curve A of a stabilized feed-back amplifier matches the lossfrequency curve C of the section of submarine cable with which it is associated at or near the limits of the frequency band to be transmitted, but is slightly above it over the main portion of the band when the tubes are new. By this means the matching improves as the tubes age for the first part of their life. The amplifiers are fed with power over the transmission line, the power currents being separated at the repeater by a constant resistance bridge 45, 46, 47. All the repeaters in the cable may be alike, or some may compensate for the accumulated distortion of the preceding cable and repeaters.
