Title: Machine for cutting tobacco and similar material
IPC: A24B7/10
Filed: 1928-10-24
Abstract: 316,535. United Cigarette Machine Co., Akt.-Ges. July 30, 1928, [Convention date]. Cutting and sliding vegetables &c.-A tobacco cutter, of the type in which a circular cutter is mounted on a swinging arm, is provided with a device so that the cutter which swings up to and just across the cutting area in close contact therewith, is then withdrawn axially from the cutting area and remains withdrawn during the swing back to its initial position, thus enabling the tobacco to be led forward without hindrance notwithstanding the small amplitude of the swing. A circular cutter 28, mounted on a shaft 26, is driven from the main driving shaft 3 by a system of bevel wheels and a pinion 27 on the shaft 26 which meshes with an annular bevel wheel 24<1>. The connecting wheels and shafts are enclosed in the swinging member 9 which is operated from the main driving shaft by a connecting rod 43. The withdrawal of the cutting blade from the cutting area is effected by a lever 34, pivoted in a bearing 36 and attached to the shaft 26 at 37, which carries a roller 35 held against a cam 30 by a spring 35<1>. While the roller runs on the lower part of the cam the blade is kept pressed against the cutting area, but when running on the raised part the motion of the lever 34 against the spring 39 pulls back the blade. The spring 39 is adjustable by turning a screw head 40. The swinging member is made in two parts slidably connected so that the distance between the axis of swing and the axis of rotation of the cutter can be increased to compensate for wear of the cutter and the bearing 36 in which the lever 34 is pivoted can be moved longitudinally by a screw 41. A grinding roller 53 is arranged so that at the end of the swing away from the cutting area the cutting blade impinges on it and is sharpened. The cutter head is preferably so fixed to the swinging arm that it can easily be removed to enable the cutter to be changed in case of damage by a foreign body.

Class 64(2) [Also in Group XI] In an electric heating mantle comprising an inner fabric cover 1 shaped to the bottom of a flask and carrying resistance heating wires and surrounded by cupshaped heat insulating lagging 3 enclosed between the inner cover 1 and an outer cover 2, the connection of the covers is effected by an expansible resilient ring 5 which contracts into a rigid annular recess 6 associated with the outer cover and thereby holds the edge portion of the inner cover in said recess. The ring may be an endless helical spring 5 which is sewn to the edge of the inner, glass fabric cover or is separate from the inner cover and clamps it in the recess. The heating wire or ribbon may be sewn to the inner cover. The recess may be formed in the outside of a sheet metal outer cover 2, or the top of the outer cover may be spun to turn inwardly then upwards and outwards to form a recess 6, Fig. 6, to receive the inner cover held by the spring 5. The outer cover may be flexible and of glass fabric, Fig. 3 (not shown), and a grooved cylindrical ring is placed within its top part, so that the ring 5 holds the edges both of the inner and outer covers in the annular groove. The grooved ririg may be permanently. attached to the outer cover and its lower edge may seat on the upper edge of a stand. The top of the flask may be covered by an over mantle comprising inner and outer cupshaped covers 8, 9 of glass fabric sewn together with an intermediate packing 10 of glass wool. The edge of the downwardly extending outer cover 9 has an endless helical spring 12 sewn thereto, and this ring may contract into the pocket 6 or into an annular groove in or under an annular beading 14 on the outer periphery of the lower outer cover 2. When the over mantle has a side opening, the endless spring 12 may be replaced by a plain ring of spring wire with a gap in it coinciding with the side opening, so that the spring may open when the over mantle is placed on the flask, and will snap into the recess to retain the mantle in place. Reference has been directed by the Comptroller to Specification 623,786, [Group XI].

Abstract: 976,638. Centrifugal pumps. JOSEPH LUCAS (INDUSTRIES) Ltd. Aug. 16, 1962 [Aug. 31, 1961], No. 31329/61. Heading F1C. A motor driven submersible pump comprises a housing defining a substantially cylindrical chamber in which the motor and pump rotor are coaxially accommodated, the housing having an open end pivoted with a peripheral flange for mounting the housing within a hole in a tank or other container, at least one inlet in the housing adjacent the flange, a closure member detachable from the open end of the casing by relative angular movement, a sleeve within the housing and angularly movable with the closure member and having an aperture or apertures in register with the inlet or inlets when the closure member is correctly engaged with the housing but removed from the inlet or inlets when the closure member is moved angularly to a position in which it can be detached so as to cause the sleeve to seal the inlet or inlets, and means for retaining the closure member from angular movement when in the correctly engaged position and for retaining the sleeve from angular movement when the closure member is detached. A cylindrical housing 1 has an eccentric peripheral flange 2 by which it is bolted around a circular hole in the bottom of an aircraft fuel tank. The pump body 3, together with the pump impeller 4 and the driving motor 5, is inserted into the housing 1, with cylindrical sleeves 15, 19 interposed, and held in place by a closure plate 11 which is pivotally mounted on a boss 12 formed on the pump body. Lugs 13 on the housing 1 overlap the closure plate 11 to hold the assembly in place, rotation of the closure plate being prevented by a spring-loaded plunger 18 which engages a notch 11 b in the edge of the closure plate. Extensions 17 on the sleeve 15 engage recesses 14 in the edge of the closure plate 11, whereby the sleeve is held in the angular position in which ports 16 in the sleeve align with inlet ports 8 in the housing 1 to permit flow of fuel towards the impeller 4. The impeller 4 discharges to a volute 10 formed in the housing 1. For removal of the pump body 3, impeller 4 and motor 5, the plunger 18 is depressed manually to permit the closure plate 11 to be turned into a position in which the recesses 14 align with the lugs 13. In this position of the closure plate 11, the sleeve 15 is in the position in which it obturates the ports 8 to prevent fuel from flowing from the tank to the housing 1, and the plunger 18 engages a recess 17a in one of the extensions 17 to hold the sleeve in this position. The closure plate 1, pump body 3, impeller 4 and motor 5 can now be withdrawn. At the same time, the sleeve 19, which is spring-loaded, moves downwards into a position in which it covers the ports 16 as an additional safeguard.
