Abstract: 957,016. Variable speed ratchet gear. JOSEPH LUCAS (INDUSTRIES) Ltd. April 11, 1961 [April 26, 1960], No. 14537/60. Heading F2D. An inertia-controlled ratchet gear between an input shaft 5 and two parallel output shafts 11 connected by equal gears 12, in a domestic mixing machine, comprises one or two levers 8 each oscillated by an eccentric 7 or crank on the input shaft 5 and each connected by a link 9 to a ball or roller one-way clutch 10 on each output shaft 11. The centre of gravity of the levers 8 lies near the ends remote from the links 9 whereby under decreasing loads inertia forces tend to compel the levers to oscillate about a fulcrum approaching the centre of gravity, thus imparting increasing one-way movement to the output shafts. In Fig. 4, not shown, a single lever is oscillated through a crank-block sliding in a longitudinal slot in the lever and is pivoted at its lighter end to both output links and also to one end of a pair of links, the other end of which swing on a fixed pivot pin accommodated in a widened part of the lever slot, thus limiting transverse oscillation of the lever.

Abstract: 361,301. Treating tobacco ; endless belt conveyers. MONTIS AKT.-GES., Burgstrasse, Glarus, Switzerland. May 13, 1930, No. 14694. Convention date, March 7, Void [Published under Sect. 91 of the Acts]. [Class 130.] Tobacco is moistened and treated electrically and with ozone. Tobacco from a sieve c falls between two endless metallic bands e, f through which a current is passed by brushes g, h included in an electric circuit; the circuit is completed through the tobacco. To ensure a constant current passing through the tobacco, current and voltage indicators x, y are provided and an alarm is given when the maximum voltage is reached. A relay operates water injection nozzles z, z<1> which spray the tobacco to facilitate the flow of current. Papers charged with charcoal are carried by the bands and serve to collect deposits which are removed at intervals with the paper. Hammers v, v<1> pack the tobacco between the bands. The tobacco is removed from the bands by non-metallic strippers o, o<1> and enters a chamber b in which it is shaken by rollers q and a plate r to expose it to ozone which enters at n. If then falls on to belts t, t<1> which convey it to an outlet u. In a modification one of the bands is constructed in two sections to one of which current is supplied. The Specification states that if the tobacco is passed through the apparatus repeatedly the whole apparatus is enclosed in a. conveying device so that the upper inlet c and the lower outlet u are above and below hoppers 18, 21. The tobacco from the hopper 21 is deposited on a belt 1 having driving holes which engage sprocket wheels. Pulleys 7, 8, 20, 9, and 10, 11, 13, 12 are so spaced that the belt after receiving the tobacco is flexed to form a tube. It is then driven at such a speed that the compressed tobacco therein is conveyed vertically upwards after which the tube is opened above the hopper 18 and the tobacco delivered thereto. Various ways for flexing the belt during its passage over rollers are described in the Specification.

Title: Improvements in and relating to control mechanisms for woodworking machines
IPC: B27B25/02
Filed: 1956-05-14
Abstract: 788,839. Woodworking machines. ETABLISSEMENTS GUILLIET, COMMERGNATGUILLIET ET CIE. May 14, 1956 [June 1, 1955], No. 14993/56. Class 145. The height of the feed rollers 11, 12 of woodworking machines is automatically adjusted by fixing each of their bearings 16, 17 to one end of a pivotally-mounted lever 18, 19 which, at its other end, is acted upon by the piston of a hydraulic jack 25, 26 having its discharge aperture 29 arranged in the piston 25 itself and controlled by a sliding rod 37 which is actuated through the intermediary of a cam 43 by means of a feeler 45 placed in the path of the boards 46 entering the machine. The hydraulic jack is operated by fluid from a pump 28 and the discharge of the jack is through one or more apertures 29 and an axial opening 31 in the piston 25 to a fluid trough 35. The inner end 38 of the sliding rod 37 so co-operates with the apertures 29, when the rod is actuated by the cam 43 and feeler 45 by a board 46 entering the machine, that the apertures are first blocked and the consequent increase of pressure in the cylinder 26 causes the piston 25 to move and, by contacting levers 18, 19, lifts the rollers 11, 12 to the required height. The weight of the rollers in this position are in balance with the hydraulic pressure but, when the board has moved under both the rollers, the pressure is reduced to a negligible amount ; at this stage, the cam 43 falls back under its own weight to return the rod 37 and uncover the apertures 29. The hydraulic system may further be adapted to operate mechanism for regulating the spacing of the saws or cutters by means of a secondary pipe 47 leading from the feed pipe 27 to the cylinder 48 of a valve whose piston 49 controls the flow of fluid to a hydraulic motor 53 serving to displace the saws or cutters ; as the pressure is nil during the working operation, the movement of the cutters is then prevented. It is similarly possible to connect into the pressure circuit other parts which it would be unsafe to move while the machine is in operation.
