Patent GB-116071-A (GB)
Title: Improvements in and relating to Ratchet Mechanism for Shafts particularly applicable to Spring Motors.
IPC: F03G1/00
Filed: 1917-12-13
Abstract: 116,071. De Camp & Sloan, (Assignees of Dooley, J. H.). May 21, 1917, [Convention date]. Spring power-storing mechanism.-The winding-shaft of a spring motor such as is used in phonographs or talking-machines is provided with a detent mechanism which is automatically disengaged, during the winding operation, to prevent noise. In the arrangement shown, the detent 8 is normally held in engagement with the ratchet-wheel 7 by a spring 13 which is coiled round the winding-shaft 4. When, however, the shaft is turned in the direction of the arrow for winding, the friction between the shaft and the coils of the spring causes the disengagement of the detent, which automatically re-engages with the wheel when the winding ceases. The detent may be provided with an extension 3 which prevents it from being moved away too far from the ratchet-wheel.
Patent GB-459136-A (GB)
Title: An improved advertising or display device
IPC: G09F25/00
Filed: 1935-06-28
Abstract: 459,136. Gramophones. DAY, H. L. V., and DAY, E. H., 17, Lisle Street, Leicester Square, London. June 28, 1935, No. 18614. [Class 40 (ii)] [See also Group XVIII] A display cabinet 1, having windows C<1>, C<2>, C<3>, C<4>, C5 through which advertisements, objects, &c. arranged in compartments behind the windows are seen when lamps in the compartments are illuminated, is combined with a gramophone &c. 5 and with mechanism which automatically lights each compartment in turn while the gramophone reproduces speech relative to the objects in said compartment. The gramophone pick-up 4 is arranged to begin at the middle of the record 3, and mechanism is provided whereby the arm is raised at the end of the traverse, transferred back to the middle of the record, and lowered thereon for repetition. This mechanism comprises a shaft 12 driven by the gramophone motor 8 and geared to a vertical shaft 15 carrying a fast and a loose pinion 18, 19 respectively. The pinion 19 is geared to a pinion 21 fast on a vertical spindle 20 which carries at its top a turn-table 34 furnished with a flat hump 35. A universally pivoted rod 36 carries an arcuate plate 39 supporting a runner 40 on an L-shaped arm 41 fixed to the pick-up arm 7. The rod 36 rests on the table 34, and when this rotates is raised by the hump 35, thus lifting the pick-up 4 off the record. A cam 28 driven by the shaft 12 rotates once for each traverse of the record and pushes a spring-pressed arm 30 to tilt a bell-crank 25 against the action of a spring 32. This releases a pin 27 on an arcuate ratchet 21<1> pivoted at 23 to the pinion 19, and allows a spring 24 to pull the ratchet 21<1> into engagement with the pinion 18, thus locking pinions 18 and 19 and starting the table 34 rotating. The crank 25 has returned to meet the pin 27 after one revolution thereof, thus automatically stopping the table 34 after one rotation. The swinging of the arm 7 back to the middle of the record is effected by a pin 42 on the table 34, which strikes against an adjustable face 47 of an arm 44 pivoted at 43 and rigid with an upper arm 45 which is thus swung laterally against the pull of a spring 46 and pushes the arm 41 aside. The lamps in the compartments may be illuminated through mercury switches carried by right-angled rods R<1>, R<2>, R<3>, R<4>, R<5> pivoted on a common shaft and each having an adjustable screw 52 the bottom of which rests on a cam K<1>, K2, K3, K4, K<5>, all of which are mounted on a spindle 17 driven through gearing 16 from the shaft 12. Each cam has a gap into which the screws 52 fall, thus tilting in succession the mercury switches. The inoperative switches may tilt backward to allow the circuit to be completed through double poles therein, thus ensuring that one lamp only, at a time, is illuminated. Instead of mercury switches, the shaft 12 may carry switch contacts or the arm 7 control switch gear for the lamps.

Abstract: 652,123. Fairleads for fishing nets. GARROOD, H. J., and ELLIOTT, M. E. July 12, 1948, No. 18722. [Classes 78 (i) and 78 (v)] A net roller adapted to be mounted for rotation alongside the rail of a fishing vessel and built up as an open-work construction with a discontinuous surface for supporting the nets constituted by a series of separate narrow faces or ribs 15 extending along the roller and spaced equi-angularly all around and equidistant from its axis 12, which faces or ribs are separated from one another by gaps which partly accommodate the fish in the loaded nets and reduce bruising of the fish. As shown, the roller is formed of six long radiating flutes 15, each flute being pressed from a sheet-metal piece to form a circular-sectioned tube 14 and a rib 13 and a flat flange 12a, the flanges being welded to-. gether to form the central hexagonal tube 12. The whole is supported by and welded to endplates 11, a strengthening piece 21 being welded on where each tube joins an end-plate, and each end-plate is welded to a stub axle 24 which fits into the hexagonal centre-bit and which carries replaceable bearing linings so that the roller may be supported for rotation over the side of the trawler. The rotation may be free or driven by the drive of Specification 652,120. The roller may be made in unit lengths joined together by pieces welded within adjoining tube sections and within the adjoining centre tube sections. The fishing nets are hauled into the trawler over the roller and the open-work pattern thereof prevents damage to the fish. According to the Provisional Specification, the narrow faces or ribs may be made helical, or may be straight in the centre and be helical at the ends and of opposite hands, or may be rotatably mounted.

Filed: 1918-11-28
Abstract: 132,125. Roseman, S. G. Nov. 28, 1918. Brush-making machines.-Relates to improvements in the tuft-making machine described in Specification 25053/13 and consists principally in arranging the bristle magazine horizontal so that the bristles are fed to the clamping-means in a vertical position, and in so shaping the magazine that the bristle supply is automatically maintained. The magazine, shown in side view in Fig. 3 and in plan in Fig. 2, comprises a cradle 40 in which fits an open trough 47 having an upwardly curved bottom on which the bristles are stacked end-on and fed forwards by the presser-plate 52. The cradle is adapted to be moved backwards and forwards along guides 41 on the machine table during each complete operation of the machine. When the magazine is in the forward position, the bristle material is supported by a pair of bridge-pieces 55, 56, Figs. 2 and 18, provided with combs which project into the material and hold it firmly while the parting needle 75 is moved laterally through the gate 79 to separate off the requisite layer of bristles. The clamp C is carried along with the needle into the magazine and after engaging the divided layer is moved to the buncher, turning at the same time from the vertical to the horizontal position so that the bristles are in the correct position for being acted upon. The ends of the divided layer of bristles are treated with pitch or like binding medium before being withdrawn from the magazine. The frame carrying the bunching jaws is adapted to slide in the guides 150, Fig. 2, so that as the clamp C brings a layer of bristles from the magazine, the bunching jaws are positioned so as to close upon such layer. The bunches or tufts are ejected from the jaws by ejector pins as the frame moves backwards.

Filed: 1930-07-01
Abstract: 358,514. Gas turbines. KNAFF, A., MAYER, L., and WOLTER, J., 33, Avenue Monterey, Luxembourg. July 1, 1930, No. 19914. [Class 110 (iii).] In a gas turbine with a revolving feed bucket wheel Z between the air compressor K and the turbine T, the buckets are charged in succession with air supplied through a passage P and then with fuel, or a mixture of fuel and air, by means of a nozzle B and, on the buckets entering a pressure-equalizing chamber E leading to the jet nozzles, the mixture is ignited and the combustion gases flow into the chamber, the buckets being scavenged as they pass a passage Q through which air is forced from the passage P. The nozzle B may be arranged so that the buckets are charged with fuel, particularly highly combustible liquid or pulverulent fuel, as they enter the chamber E. At starting, ignition is effected by a sparking-plug K<1> in the chamber E. The operations may be repeated any desired number of times during a single revolution of the wheel. The residual burnt gas in the buckets leaving the chamber E may be allowed to expand in stages through passages on the turbine side, and supplied to other stages of the turbine, before scavenging is effected at the passage Q.
