Title: Starting apparatus for internal combustion engines
IPC: F01L13/00
Filed: 1919-08-18
Abstract: 153,966. Norman, G. H., and Smith, W. S. Aug. 18, 1919. Starting.-A multi-cylinder engine is started by charging one or more selected cylinders with explosive mixture under pressure and the remaining cylinders with mixture at atmospheric pressure, and firing the charges consecutively. The mixture is supplied by an auxiliary internal-combustion engine, one cylinder of which acts as a. pump, drawing mixture from the carburettor of the auxiliary engine. A non-return valve on the pump cylinder outlet may have a manual release to facilitate the starting of the auxiliary engine, and a loaded valve may be arranged to return mixture to the induction system when a predetermined pressure is reached. The mixture from the pump preferably passes through an engine-driven distributing- valve, Fig. 8, comprising a rotary member 43 with ports 44 in communication with the conduit 47, 46 from the pump and registering in turn with ports 41 in a fixed member 40 leading through pipes 20 to non-return valves 50 on the cylinders of the main engine. Some of the ports 44 are fitted with loaded valves 49, which do not open until a sufficient pressure is reached in the cylinders supplied through the other ports. A small permanent leak hole may replace the valve 49. The non-return valves 50, which admit the starting-mixture to the main engine, may be contained in valve casings 51, Fig. 9, fitted around the sparking-plugs 53 and secured by screwing in the plugs. The outlet passage 52 from the casing 51 communicates through ports 56 with the interior of the sparking- plug. Leakage past the valve stem may be prevented by a cover 59 fitted with a valve 61, which can be used as a plunger for freeing the valve 50 in case of sticking. The starting-mixture may be ignited by the magneto of the auxiliary engine, one terminal of the magneto distributor being connected to the distributor of the main engine. The Provisional Specification states also that the starting-mixture may be supplied by a hand pump.

Title: Automatic coupling systems for railway cars
IPC: B61G5/08
Filed: 1972-05-03
Abstract: 1363183 Rail vehicle couplings DRESSER INDUSTRIES Inc 3 May 1972 [12 May 1971] 20604/72 Heading B7T A railway vehicle automatic coupling system comprises a main air line 40 adapted to be connected to a corresponding air line of another vehicle, and a main valve 41 interposed in the air line and controlled by a network including valves 45-48 as described in Specification 1,274,714 and indicated by numeral 44 therein, the present invention further including a check valve 100 which receives pilot air from the output line 65 of valve 46 and operates to restrict air flow through line 76 from the left hand end of line 40 through valve 60 and line 51 so that when the vehicle is coupled to another vehicle with pressurized air in its main air line this air cannot pass to valve 45, which if open will cause valve 41 to open and hence vent this air, unless the other end of the vehicle is coupled.  If the said other end is coupled valve 48 will open valve 46 and allow pressurized air to pass to line 65 and then to line 102 when it will open valve 100 and allow air into valve 45. A time delay 118 ensures that valve 45 will not be opened unless a good coupling is made. Should valve 48 only operate for a short time a spring 96 will quickly close valve 46. A further check valve 110 in parallel with valve 100 obtains its pilot air from line 40 which when charged with air will cause valve 110 to open and allow pressurized air to pass to valve 45. Thus should valve 48 fail and cause valve 100 to close air will still be able to reach valve 45 through valve 110 and retain valve 41 open.

Abstract: 295,507. Asquith, Ltd., W., (formerly Asquith (1920), Ltd., W.), and Feather, G. Aug. 6, 1927. Drilling-machines.-In a radial arm drilling- machine the arm is locked to the pillar and the carriage is locked to the arm by the same control member, the first portion of the movement of the member serving to lock the arm and the final movement serving to lock the carriage. A locking shaft A extends through the drill carriage c and along the arm (not shown) and is rotatably mounted at one end in a bearing D on the arm. A sleeve b<3>, splined to the shaft, is rotatably attached to the carriage by an annular recess b<4> and a plate c<1> on the carriage and is connected by a crank pin and link b<1> to a crank pin on the boss b of a control lever B. As the control lever B is pulled downwards from the position shown its first action is to rotate the shaft A and lock the arm sleeve b<5> to the pillar by the mechanism shown in Fig. 3, but when the crank pin on the lever is almost at its dead centre a stop a<1> on the shaft engages an adjustable stop d on the fixed bracket D and prevents further rotation of the shaft, whereupon movement of the lever just over the dead centre causes the carriage to be locked on the arm through binding of the spline connection between the sleeve b<3> and the shaft A. According to the Provisional Specification the stop a<1> may be adjustable in a recess on a collar secured to the shaft A.

Current flowing through the switches (99, 100) energizes a solenoid (94), Fig. 2 (not shown), to lower a locking pin (98) into a matching hole in the cassette 16; switches on a lamp 52 to illuminate the card 32; and energizes a motor to draw a carriage 62 to the right (as seen). As the carriage 62 moves, a rod 92 rides along a cam surface 90 of a member 84 to lower a light seal 88 on to the upper surface of the cassette 16. Simultaneously a roller 74 rides up on to the top surface and pivots a support member 68 thereby lowering a pen 80 into a hole in the cover 18. Further movement of the carriage 62 opens the cover 18 fully, the apparatus then being in the solid line position shown. By this time a motor 64 turns a shutter 44 to align an aperture 46 thereof with the lens system 42 and the film underneath the window 18 is thereby exposed. The mechanism is then returned to the dotted line position shown with the cassette 16 ready for withdrawal. The apparatus also includes a voltage control system to compensate for variations in the voltage supply to the lamp 52. A three position switch 118 is provided for the exposing of films of different sensitivities, each switch position resulting in a different lamp intensity. In another embodiment, Figs. 6-8 (not shown), the cassette (16') and the data card (32') are inserted in adjacent vertical slots, and a lens and mirror system (156-160) is provided to expose the part of the film in the cassette in conjunction with a similar shutter mechanism.
