Title: Bobbin-thread pull-offs for lock-stitch machines
IPC: D05B51/00
Filed: 1929-09-24
Abstract: 328,533. Fairweather, W., (Singer Manufacturing Co.). Sept. 24, 1929. Lock-stitching by hooks. - The stop-lug 55 depending from the throat plate 2 engaging a stop-shoulder 44 to prevent rotation of the bobbin carrier in one direction, is displaced a substantial distance from a line intersecting the throat plate needle-aperture transversely of the line of feed. The spool carrier and rotary hook are rotated from the shaft 15 by the bevel gears 16, 17 at twice the rate of the needle reciprocation. The looper body 22 has a loop-taking hook 28 and supports the spool case 23 which has an interrupted bearing rib 24 fitting between flanges 25, 26, Fig. 3, on the body. An auxiliary hook 31 on the spool carrier directs the needle-thread loop towards the bottom of the carrier. The bobbin 33 is latched in place by the spring 35. A thread-slit is provided in the bobbin carrier for passage of the thread. This slit is bridged by a tension spring 46. As the hook 28 enters the needle loop, it carries it against the face of a lug 53 below the throat plate 2, causing the loop to be rapidly spread and cast round the carrier 23. The usual intermittently vibrated finger 56 is provided to oscillate the bobbin carrier in a direction opposite to that of the loop taker 28, such oscillation being limited by a stop-finger 64 engaging the shoulder 41. To nullify the varying inertia effects of full or empty bobbins on the quality of stitching, the feed-dog 71 is provided with a rib for pulling off bobbin thread during its downward movement.

Title: Improvements in or relating to selective calling systems
IPC: H04M1/50
Filed: 1947-10-31
Abstract: 657,894. Exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Oct. 31, 1947, No. 29100. Convention date, Dec. 13, 1946. [Class 40 (iv)] [Also in Group XXXVIII] Calls may be extended by radio from a toll board to mobile stations. Numbers dialled at the toll board are registered and transmitted as tone signals which are applied as successive modulations to a radio transmission. The dialled digits are registered on switches TH, H, T, U. An oscillator 31 associated with time constant networks 41 and the four register switches mark the networks so that four pulses may be transmitted successively with voice frequencies characteristic of the digits. Slow release relays are marked SR. When key 7 is operated relay 9 follows the impulses and relay 16 repeats them over a distributer RC to switch magnets 17 ... 20. The distributer is stopped when dialling relay 14 falls back during an interdigited pause. When the fourth digit has been registered, relay 22 is operated and the relays 27 to 30 operate and release in sequence to connect the marked networks 41 to the oscillator. Each relay operates only during the period of charge or of discharge of an associated condenser. As relay 30 falls back after the fourth digit, condenser 62 discharges through relay 24 which locks and completes a homing circuit for the distributer RC over the wiper B4 of the fourth bank. The register switches follow the distributer and return home in turn. The oscillator 31 is connected to a radio transmitter 57 through an amplifier 48 and contacts of relay 55. Relay 55 is operated as soon as the distributer moves off normal. To prevent the successive transmission of two pulses of the same frequency, corresponding terminals of the first banks of the register switches are strapped together. If the same digit is dialled successively relay 10 operates an alarm 65 and short circuits 27 to disable the oscillator. Receiving systems with means for detecting a call number transmitted in this manner are described in Specifications 630,815, [Group XL (c)], and 630,819, [Group XXXVIII].
