Title: Improved manufacture of lead pencils
IPC: B43K19/16
Filed: 1925-09-24
Abstract: 250,828. Kuhula, R. Sept. 24, 1925. Pencils.-Lead pencils, having a sheath composed of a fluid artificial composition which solidifies in the air and is capable of being cut, are manufactured by dipping rods or wires into the fluid composition, removing them and allowing at least the outside of the composition to dry, and then repeating the operation until a sufficient thickness has been obtained, the rods being finally withdrawn from the composition and replaced by sticks of lead coated with an adhesive. If desired, the leads themselves may be subjected to the dipping-process. The sheaths before they have become hard may be subjected to pressure insufficient to produce an appreciable compression, in order to increase the uniformity and to form any desired shape. This pressure may be applied before the sheath has attained its desired size, and the dipping then continued. The rods or wires may be coated with oil or with an inert powder to facilitate their withdrawal when the composition has, set. The composition consists of a binding-agent such as glue, collodion, or other gelatinous material of animal or vegetable origin, and filling-materials preferably wood-meal, with or without the pulverulent materials and colouring-matter.

Mechanical stoking; doors. -In mechanical stokers which project the fuel into the furnace such as duescribed in Specification 7418/99, the projecting means are protected from the heat of the furnace bv movable doors which are actuated by the stoker mechanism to allow the fuel to be projected into the furnace. In the arrangement shown in Fig. 2, a door h mounted on a shaft i is arranged in front of the box c in which the shovel e moves. The shaft g of the shovel actuating mechanism carries a pinion w provided with interrupted teeth x which engage with an idle wheel u geared to pinion t on the shaft i. During rotation of the pinion w the shaft i is raised at intervals to permit firing and allowed to descend by its own weight to protect the shovel when it is retracted. The door h. may be pivoted on its lower edge or may be formed in two parts each of which is pivoted on a vertical axis at the side of the fuel discharge opening. A modification is shown in Fig. 6. in which the door h is pivoted at n and moved in a vertical plane by an arm 5 pivoted to the door at 6 and at 8 to link 7 supported on the frame 10. The link 5 is actuated by a cam 2 driven by the stoker and engaging with a roller 3 carried by the link 5. The door h may also be operated by a pinion having interrupted teeth engaging with a toothed segment formed on the door. Fig. 9 shows a further modification in which the doors o, p are supported by levers 15 pivoted at 16 and actuated by links 17 driven by a link 19 carrying a roller 21, which is engaged by a cam 2 on the shaft g.

[Also in Group XXVIII] Fuel is supplied at constant pressure to an oscillation chamber 25 in which it is set into oscillation by the cylinder pressure variations at the same frequency as the pressure variations but with a time lag, whereby fuel is injected through the orifice 23 on the compression stroke. The fuel is supplied through a pressure regulating valve 36 and a distributer 38 and a charge collected in chamber 25 is forced upwards against a resilient gas cushion 29 when combustion occurs in the cylinder. The fuel returns towards orifice 23 during the compression stroke and its inertion causes some fuel to be injected through orifice 23. The gas cushion 29 may be replaced by a diaphragm or spring-loaded piston. The valve 36 is controlled from the accelerator pedal 41 and by a suction responsive device 18. In Fig. 3 the passage 23 of the oscillation chamber contains a non-return valve 58 and a plug 56, with orifice 57, separates a gas space 29 above the fuel. The fuel may be gaseous.
