Title: Improvements in methods and apparatus for the manufacture of tubes made of a fusiblematerial which can be drawn out, in particular glass tubes
IPC: C03B15/14
Filed: 1929-01-22
Abstract: 304,664. Favre, P. A. Jan. 23, 1928, [Convention date]. Drawing ; forming glass tubes.-Relates to the method of making tubing, described in Specification 300,646, in which a glass cylinder a, Fig. 1, with an axial bore, is threaded on to a tubular former b and its lower end is heated by gas flames. The glass melts and flows over the bulbous end b<1> of the former, and is drawn off by suitable drawing-devices. The present invention consists of a number of modifications of the apparatus described in the prior Specification. The former b may be made of refractory earth, and it may be surrounded by an oven consisting of a bottle-shaped casing r which is heated by any suitable means. A number of cylinders a, a<1>, a<2> may be threaded on the former b, a new cylinder being added as the lowest one is consumed. Instead of a cylinder a, two half cylinders, or a bundle of rods, may be assembled around the former b. The glass cylinders a can be replaced by a refractory tube t, Fig. 2, which surrounds the former and is filled with broken glass. Molten glass may also be poured into the top of the tube t, the heating-arrangements being modified so that the glass at the bottom of the tube has the necessary stiffness. In a modified construction, shown in Fig. 3, the former b is inverted and is formed integral with a dished member n. Molten glass a<3> is ladled into the member n and is drawn upwards over the bulbous enlargement b<1>, the draw being started by means of a bait ring o.

Title: Speed changing transmissions
IPC: F16H3/62
Filed: 1973-01-19
Abstract: 1368405 Variable ratio epicyclic gearing DANA CORP 19 Jan 1973 [24 Jan 1972] 3001/73 Heading F2D In a planetary transmission comprising a plurality of independently rotatable ring gears and selectively operable mechanism for locking a selected one of the ring gears against rotation, a pawl locks one of the ring gears against rotation in at least one direction at such time as all of the ring gears are released by the selectively operable mechanism, e.g. if the latter is inadvertently positioned intermediate two ratios, and the pawl is retracted from such locking engagement with the ring gear upon actuation of the selectively operable mechanism to lock one of the ring gears against rotation. As applied to a bicycle, the transmission is contained in a housing 72 mounted on the shaft 42 carrying the pedal cranks 38, 40 and held against rotation by a bracket 211 engaging a frame member 20. A cluster of sun wheels 90, 92, 94 rotatable on the shaft 42 has a splined connection with an output sprocket 32, each sun wheel meshes with a diametrically opposed pair of planets 96, 98, 100, only one of each pair being shown, mounted on a carrier 102 splined on the shaft 42, and the planets mesh also with respective ring gears 82, 84, 86. Angular movement of a shaft 168 establishes a selected ratio by allowing one of three latch bolts 144, 146, 148 to be urged inwardly by a spring 202 to a position in which it enters one of a plurality of notches 156, 158, 160 on the periphery of each ring gear to hold the gear against rotation in the direction F. Associated with one of the ring gears, preferably and as shown, the low-ratio gear 82, is a pawl 280 pivotally mounted at 292 and having a portion 294 extending into the path of all of the latch bolts so that should none of these be in its inward position the pawl is rocked by a spring 296 to a position in which its end 300 enters a notch in the ring gear 82 to lock that gear against rotation in the direction R so that reverse rotation of the pedals may be transmitted to a coaster-brake in the hub of the driving wheel of the bicycle. The pawl will also be engaged on back-pedalling should any of the transmission ratios be engaged since the operative latch bolt will be raised by a cam surface 151 on rotation of the corresponding ring gear in the direction R. The pawl may have a spring- loaded secondary pawl at its end 300 whereby the amount of reverse rotation permitted the ring gear 82 before it is arrested is reduced. In a further modification an additional pawl is provided to arrest the ring gear 82 also in the forward direction F, and the amount of rotation permitted the gear in either direction before it is arrested is reduced by the provision of additional notches in its periphery.
