Title: Improvements in or relating to means for effecting movements in accordance with changes of light intensity and to apparatus operated thereby
IPC: G01J1/54
Filed: 1942-09-15
Abstract: 559,973. Photometric apparatus. VENNER TIME SWITCHES, Ltd., and NORRISH, R.G.W. Sept. 15, 1942, No. 13028. [Class 97 (i)] [Also in Group XXXVII] Incidence of light on a deformable container causes alteration of pressure and hence of shape, due to distortion of a predetermined quantity of material contained therein, e.g. nitrogen peroxide, nitrosyl chloride, chlorine or bromine and is utilized in switching operations or in releasing spring controlled mechanisms. Speed of actuation may be controlled by adding such substances as nitric oxide, which acts as an accelerator, or nitrogen which serves as a diluent. In the example described a switch contact 16 is moved from one co-operating contact 17 to another 18 when light, falling on a bourdon-tube 12 made of glass, anodized aluminium or magnesium, causes deformation. As described, these contacts with adjusting means are mounted on one side of a partition in an inert gas filled glass container relay means being mounted on the other as follows. Contacts 3, 4 are connected to a source of electric current and 3, 5 to a load, for example by means of suitable plug-pins. With relay contacts 44, 45 and 46, 47 as shown current will be supplied to the load through contacts 56, 57. If the effect of the light causes vessel 12 to deform moving contact 16 to contact 18, relay 50 will be energized, attracting armature 49. Pin 54 now separates contacts 56, 57, contacts 46, 47 are allowed to close, and spring 63 pulls arm 64 of armature 60 to latch armature 49 and, by projection 62 to open contacts 44, 45. When light allows vessel 12 to assume normal shape, contacts 16, 17 re-engage, relay 59 is energized, releasing armature 49 and restoring contacts 44, 45 and 56, 57. Thus, the energizing of each relay serves to stop the current through it and to prepare the contacts for subsequent energization of the other.

As applied to the machine described in Specification 213,594, the welt-butting knives 346, Fig. 2, are each provided with a clearing member 522 carried by a longitudinally sliding shaft 521 operated by a lever 525 pivoted at 526 and provided with a roll 543. This mechanism is mounted on the cutter carrier 344 which has a four-motion movement, as described in the prior Specification. As the carrier moves forwardly of the shoe and above the plane of the sole on return from the cutting stroke the roll 543 engages a cam surface 514 and the clearer scrapes waxed threads and wax from the knife and removes the severed waste end of the welt. The clearer is returned by a spring 545 and spring-held bumper 538 which engages a tail 547 on the lever 525 at the end of its travel. On the cutting movement of the carrier 344, the roll 543 travels beneath the cam 544 and is not operated. The treadle 136, Fig. 3, operates the clutch only. As soon as the machine starts, a cam disc 241 actuates a lever 768 connected by a link 790 through a spring 798 with an arm 796 on the rock shaft 278, which operates the last supports as described in the prior Specification. The swinging side frames carrying the welt supports are operated by a rock shaft 144, as described in the prior Specification. In the present construction, these are adjusted for size of shoe by a cam turned by a hand-wheel and engaging an arm 740 on the rock shaft. As the lever 768 moves, a pawl 776 thereon slides off a shield 782 and engages teeth 778 on a slide backed by a spring 752 which resiliently operates a rod 748 adjustably clamped to a bar 746 pivoted to the end of an arm 230 on the rock shaft 144.
