Title: Improvements in propeller pencils
IPC: B43K21/08
Filed: 1925-12-15
Abstract: 256,110. Bina, F. C., and Barrey, F. F. Dec. 15, 1925. Pencil holders. - In a pencil holder of the screw-propelling type, the propeller is in the form of an arm arranged transversely to the axis of the holder and bearing transversely on the lead, means being provided for moving the arm out of propelling position to enable a lead to be inserted through an opening in the cap and then returning it into position for ejecting the lead. The propeller is in the form of a staple-like piece of wire 7 having a straight back position slidable in a longitudinal groove 10 in the band 2, an upper projecting portion 8 extending through the coils of a rotatable wire spiral 4 into the central passage, and a lower projecting portion 9 extending into a lower coil of the spiral but not into the central passage. 'The lower end of the spiral rotates on a metal ring 15 in the barrel and the upper end is connected to a disc 5 having peripheral notches engaged by indentations 17 in the operating-cap 3. The spiral is of such a length that it acts as a spring to hold the disc 5 in contact with the cap. The upper end 19 of the spiral is enlarged and rotates freely in a space between the upper end of the barrel and the disc 5. When the portion 8 - of the propeller is retracted beyond the upper end of the barrel, the enlarged part of the spiral turns the propeller on the straight portion lying in the groove 10 to remove the portion 8 out of the central passage. A lead can then be inserted through openings 11, 18 in the cap and disc 5. The cap 3 is rotatably held on the rear end of the barrel by means of a split spring ring 12 engaging grooves in the cap and barrel. The lead is held by means of a split metal tube 21 having a tapered end mounted in the pointed portion of the barrel, and the tube may also be provided with a spring tongue. When the barrel is made of non-metallic or composition material the point may be strengthened with a metal tip having a reduced portion extending into the barrel.

Patent GB-920099-A (GB)
Title: Hydrauliccaly operated drop-hammer or hammering press
Inventor: BRAUER WILLI
IPC: B21J7/36
Filed: 1960-09-20
Abstract: 920,099. Hydraulic drop hammers. LANGENSTEIN & SCHEMANN A.G. Sept. 20, 1960, No. 32237/60. Class 83 (4). In an hydraulic drop hammer whose tup 4 is raised by pressure liquid admitted below a piston 2 in cylinder 1, one or more apertures 44a- 44d are provided in the cylinder wall which when opened by the ascending piston cause an exhaust valve 11 to open and exhaust the pressure liquid. Oil from a reservoir 27 is fed by a pump 6 to chamber 7 which has a by-pass outlet 26 controlled by a fluid-actuated by-pass valve 18, and a spring-loaded check valve 12 leading into chamber 9 which communicates with an aperture 5 in the cylinder wall. The height to which this hammer is raised is selected by a switch 54 which closes a circuit leading to one or other of pressure switches 49a-49d, 50a-50d; these are actuated by spring- loaded pistons 46a-46d leading to the respective apertures 44a-44d in the cylinder wall. The upstroke is initiated by foot switch 52 and when the piston 2 passes above the selected aperture, the pressure oil depresses the relevant piston 46a-46d which closes the relevant contact 49a-49d and energizes a solenoid 37 controlling a spring-centralized relay valve 28. Thus pressure oil supplied by a second pump 30 passes through pipe 32 and raises the exhaust valve 11 which opens chamber 9 and cylinder 1 to the reservoir and thus causes the tup to fall; simultaneously the valve 18 is opened by its spring 22. When the relevant cylinder aperture 44a-44d is opened by the falling piston 2, the relevant piston 46a-46d returns under spring pressure and closes one of contacts 50a-50d which energizes a second solenoid 38 of valve 28. This closes the by-pass valve 18 by pressure oil admitted through pipe 24 to chamber 25, and also shuts off the pressure to valve 11 but the latter remains open during the remainder of the downstroke due to the oil exhausting through ports 42. When the tup strikes the workpiece, however, the valve 11 closes under spring pressure and the valve 12 re-opens to start the next upstroke. A holding relay 58 is provided across foot switch 52 and a safety valve 14 and shock absorber 15 are provided in chamber 9. German Specification 970,878 is referred to.

Title: Improvements in spring motors
IPC: G11B17/00
Filed: 1920-11-16
Abstract: 175,082. Goold, R. L., (Brunswick-Balke- Collender Co.). Nov. 16, 1920. Centrifugal governors.-In a spring motor, a worm gear 28, Fig. 5, on the spindle 12 drives a worm shaft 29, which carries a centrifugal governor consisting of governor springs 30 and weights 31 disposed within a drum 32 upon which a friction pad 38 operates. The pad 38 is carried at one end of a lever 36, Figs. 3 and 5, pivoted at 37, the other end being forked and formed with separate fingers 36<1>, 36<11>. The finger 36<1> operates in a spiral groove 39 on a pin 39<1> which can be turned by means of the head 40. The rotation of the head 40 causes vertical motion of the end of the lever 36 under the action of a control spring 42, and hence adjusts the pad 38 relatively to the drum 32.

Title: Improvements in or relating to the distillation or heat treatment of solid carbonaceous materials, especially briquettes
IPC: C10L5/28
Filed: 1934-11-09
Abstract: 450,240. Heating or distilling solid materials. BRITISH COAL DISTILLATION, Ltd., HARDY, R. D., MACHEN, C., and ARAM, E. H. G., 48, Broadway, Westminster. Nov. 9, 1934, No. 32287. [Classes 51 (ii) and 55 (i)] The charge is fed on to a shallow rotary hearth surmounted by a muffle and is arranged to be heated from above indirectly only, or indirectly and directly by heating gases admitted to the chamber below the muffle arch, heating being also applied from below the hearth by gases withdrawn from the muffle and circulated below the hearth. The charge of coal or briquettes from a hopper A is fed down a water cooled inclined plate A' on to an annular rotating hearth B, the level of the charge being regulated by a water cooled slide D. A level indicator comprises an inclined plate C which rides over the surface of the charge and indicates the necessity for operation of the slide D. The fuel, after being carried round on the hearth, is discharged by an inclined water cooled scraper E, the distillates passing through an outlet P<1> to a condenser R and exhauster O. The briquettes which pass in counter current to the heating means are subjected to a gradually increasing temperature, which is due either to indirect or direct heating or a combination of both. Producer gas entering through ports E<1> is burned in air entering through inlet O<1> heated in the oven cover and supplied through air bricks G, the combustion gases passing along a flue H and heating the muffle arch J before passing to the stack K. To apply direct heat, the stack valve L is closed, and the gases pass through conduit M when they are mixed with a portion of the cooled stripped distillation gases and enter a mixing chamber Q<2> having ports Q leading to the inside of the muffle. The fuel layer is heated on both sides by feeding it on to a false hearth Q<5>, Fig. 5, above the hearth B, flue gases passing from the mixing chamber Q<2> through a duct Q<3>, leading to the hollow space Q<4>, the hot gases passing round this space to an outlet port diametrically opposite the inlet port Q<3>. A sand seal Q' prevents the distillates from mixing with the heating gases. When direct heating is applied the hot gases pass through the ports Q as previously described, the relative pressures in the mixing chamber Q<2> and the muffle chamber being adjusted. The Provisional Specification refers also to Specifications 18471/14 and 181,863, [both in Class 51 (ii)].

Filed: 1964-08-07
Abstract: 1,073,414. Manure distributers. JOSEF DECHENTREITER MASCHINENFABRIK G.m.b.H. Aug. 7, 1964 [Aug. 8, 1963], No. 32362/64. Heading A1D. [Also in Division B8] An agricultural trailer having an endless conveyer 11 over-its floor for loading and unloading material has an intermittent pawl and ratchet drive for the conveyer. The chains 29'of the conveyer 11 are driven by sprocket wheels 28 on a shaft 27 also having a ratchet wheel 31. A chain 15 from the trailer's drive shaft drives a shaft 13 which by a chain 19 drives a sprocket wheel 20 having an eccentrically mounted disc 22 which reciprocates a lever 32 mounting a pawl 37 which drives the ratchet wheel 31 whose return movement is prevented by a pawl 44. A lever on the trailer can move a rod 42 to alter the initial position of the lever 32 to vary the magnitude of the intermitent movement of the conveyer. If a continuous feed is required a pin 47 locks the sprocket 20 to a sleeve 23 to effect a drive of the shaft 27 through a chain drive 24-26. The speed of this continuous drive is such that it renders the pawl drive ineffective and prevents locking of the parts. The vehicle may be used as a manure spreader.
