Patent GB-168139-A (GB)
Title: Locomotive stoker
IPC: F23K3/04
Filed: 1920-05-21
Abstract: 168,139. Lower, N. M. May 21, 1920. Mechanical stoking.-Fuel is projected over the grate of a locomotive fire-box by a reciprocating shovel 9, and is distributed laterally by oscillating vanes 25 which may operate independently or in conjunction with laterally directed blast nozzles 34. Automatic and adjustable means are provided as described in Specification 168,140 to control the admission of pressure fluid to vary the interval between heavy and light fuel injections and consequently varying the quantity of fuel supplied with each type of injection, thus ensuring uniform distribution of the fuel. The shovel 9 is attached to and is reciprocated by a hollow piston 7 which works in a casing 2 and contains an internal stationary plunger 15 which is secured in position at the front end of a spring casing 13, to which the pressure fluid is admitted through the passage 10 to operate on the rear face of the piston head 6. When the piston 7 is in the retracted position, the pressure operates only on an area equal to the internal area of the spring casing 13, thus ensuring a small initial velocity of the piston. The movement of the piston immediately exposes its full area to the pressure supply, and admits pressure to the distributing-nozzles 34 through the opening 30 in the piston head. The vanes 25 are pivoted to the shovel 9 at 26 and are provided with short outwardly extending arms 27 which move in grooves 28 in the casing 2. Fuel is fed from the casing 3 upon the shovel 9, the position of the vanes 25 when the shovel is retracted being shown in plan in Fig. 2. The outward motion of the shovel brings the arms 27 into contact with the shoulders 28<a>, giving the vanes a rapid motion substantially at right-angles to the path of the shovel, thus laterally distributing the fuel lying outside the vanes. The retraction of the shovel, by means of the tension spring 12, also retracts the vanes 25 by contact with the casing 2 and by engagement of the arms 27 with the shoulders 28<b>. The intensity of the lateral distribution effected by the vanes 25 depends on the speed of the shovel, and at low speeds the blast nozzles 34 become operative to assist lateral distribution. The relatively small pressure producing a light injection passes through the opening 30 and creates a blast as desired, but with a heavy injection the higher pressure is sufficient to close the spring-loaded valve 31 against the passage 33 and no blast is produced. Fuel is elevated and fed to the casing 3 by apparatus fully described in Specification 168,138.
Patent GB-647022-A (GB)
Title: Cast iron castings
IPC: B22D19/00
Filed: 1948-05-24
Abstract: The first step in a two-step process of making cast-iron castings comprises making a casting having a structure consisting of free graphite in a pearlitic matrix and the second step comprises heating the casting above the critical temperature for sufficient time to produce a predominantly austenitic structure, then quenching in a bath between 350 and 1000 DEG F for one hour or more until substantially all the austenite has transformed to an intermediate product leaving no retained austenite and finally cooling to room temperature.  The casting may be made according to Specification 590,344 and quenched at 500-650 DEG F for four to six hours.  The quenching temperature is governed by the thickness of the casting, e.g. 1 1/2 to 4-inch sections are quenched at 450-500 DEG F and over 4-inch sections at 350-400 DEG F.  U.S.A. Specification 2,200,765 is referred to.
