Title: Apparatus for gathering, delivering and transferring materials
IPC: B65G65/28
Filed: 1919-06-11
Abstract: 150,587. Stuart, F. L. June 11, 1919. Conveying and elevating apparatus.-In apparatus for transferring materials, including a boom conveyer mounted at its inner end to turn about both vertical and horizontal axes, as described in Specification 146,762, a gathering device carried by the outer end of the boom conveyer is supported by a tractor arranged directly beneath it which serves to move the conveyer about the vertical axis. The gathering-device comprises a double-ended plough R, a belt conveyer r<1> and a hopper r<3>. The frame r<2> of the conveyer is detachably connected to the boom M so that it may be replaced by a gathering-device in which the plough enters endways into the material. The frame r<2> of the conveyer is supported by an endless-track tractor S which, in addition to moving the boom conveyer and gathering-device about a vertical axis, may also move the boom conveyer longitudinally. The hopper r<3> is pivoted at r<4> so that it may be raised out of the way when the boom conveyer is discharging material. In a modification, the gathering-device is pivotally connected to the boom M so as to move independently in an horizontal plane. In another modification. the plough enters the material endways instead of sideways. In all constructions, the boom conveyer may be lowered and moved in one direction about its vertical axis bv a cable T and winch T<1>.

Title: Improvements relating to internal combustion engines working with liquid fuel
IPC: F02M31/18
Filed: 1921-12-06
Abstract: 191,252. Saunt, T. W. Dec. 6, 1921. Vaporizers, external.-The vaporizer comprises a box containing a quantity of fusible metal such as lead which remains molten and presents a level surface over which the fuel spreads even when the vehicle is on a gradient. The box is heated by a wickless burner arranged in the lower part of an enclosing casing. Fig. 1 shows a box A having tubular pockets B in its lower wall and having an outlet pipe C with a lateral branch D leading to the annular chamber E of a carburettor F. Air is admitted through adjust. able holes K to a concentric tube H through which the flow is controlled by a screwed needle M. In a modification the vapour enters through an axially arranged pipe which can be adjusted towards or away from the choke tube. A pipe N concentric with the pipe C admits liquid fuel from a pipe O to the box A where it is vaporized as sub-atmospheric pressure. The pipes D, O support the box A in a casing Q in the lower part of which is arranged a burner comprising a tube T and heat-concentrator V in which are air inlet holes W. Oil is supplied to the tube T through a lateral pipe Y and issues through a nozzle Z which can be cleaned at intervals by moving a plunger 1. Primary air for combustion enters through a hole 7 and passing up a casing 6 to the holes W mixes with the fuel from the nozzle Z. The mixture enters a hole in the lower of two domes 8, 9, the outer dome having a series of peripheral holes so that flames impinge on the concentrator V. Additional air for combustion is supplied through a separate inlet S. A pillar 21 supports a mass 22 of refractory material which serves to reignite the burner after the plunger 1 has been used. A wick 11 of asbestos supplied with oil from a branch pipe 12 or with methylated spirit surrounds the casing 6 and serves for starting the burner. The fuel issuing from the pipe N may be preheated by being passed through a coil in the flue of the vaporizer. A modified form of burner is described in which two flat circular discs connected by a perforated circumferential strip replace the domes 8, 9. The box A normally contains molten metal on to which the fuel from the pipe N drips. Fig. 3 shows a modification in which a chamber 45 has a hemspherical base with external pins 46, and is provided with internal baffles 48, 49 to control the motion of the molten lead. In the vapour outlet pipe C<1> is arranged a nozzle 50 through which air, oxygen or inert gas such as the exhaust is drawn to mix with the vapour when induced by the engine suction. A check valve may control the air &c. The lower part of the chamber 45 has a projection 52 that fits into a perforated tube of nickel, nickelchromium alloy, porcelain or other refractory material which fits over a similar projection 54 on the dome 9 of the burner. This tube is filled with lumps of refractory material and has the same function as the mass 22 shown in Fig. 1.
