Filed: 1952-05-19
Abstract: 701,957. Band brakes. UNITED STATES STEEL CORPORATION. May 19, 1952, No. 12625/52. Class 103(1) The spaced brake bands 15 and 15a on the hoist drum of a well drilling draw works are anchored at one pair of ends on an equalizer beam 37, and have their other active pair of ends applied by a hand lever 29 operating through a shaft 28 crank arms 32. The arms 32 have connected to them links 35 which are coupled to levers 34 which act upon the ends of the brake bands and are pivoted about pins 33 carried by ears 24 integral with the base plate member 22. In applying the brake, clockwise movement of lever 29 and the crank arm 32 constantly shortens the lever arm between arm 32 and link 35, constantly lengthens the lever arm between the link 35 and the lever 34, and constantly shortens the lever arm between the lever 34 and the live end of the brake band. Therefore the mechanical advantage increases with the movement of the hand lever 29. The equalizer beam 37 is pivoted on a bracket 26 having sockets 40 and 40a receiving cushioning springs 41 and 41a. Rollers 16, 16a and 17, Fig. 3, a spring 18 and a set-screw 19 position the brake band. A sand reel brake drum and band 20 is operated by a second handlever 42, Fig. 2.

Force-transmitting mechanism. - In transmission apparatus for brakes of the kind described in the parent Specification the means employed to alter the ratio of transmission comprise wedges which are moved automatically into position. The brake lever 2 is pivoted at 7 to plates 6 connected to a block 9<1> sliding between four guide bars 5. A slotted link 11 is pivoted to the lever and has sliding connection with the pivot 13 of a bell-crank lever 12. A link 14 operating a second bell-crank lever 16 is pivoted at 13 and the link 11 bears against a spring 17 connected to the link 14. The bell-crank levers are connected to wedges 20, 21. When the brake rod 1 is moved to the right the lever turns first about a pin 3 which rests against an abutment 4, the wedges being moved to fill the gap between an abutment 22 and the block 9'. After the brakes are in contact with the wheel the point 7 forms the pivot of the lever. In the form shown in Fig. 3 the mechanical advantage obtainable is variable in accordance with the weight on the vehicle by virtue of the displacement of a sliding abutment 29. A single wedge 20 is employed and this is interposed between the block 9<1> and a block 25 the position of which is determined by a beam 27 connected to the block 25 by bars 26 and to the lever 2 by a link 28. The beam is moved to contact with the abutment 29 about which it turns when the brakes are in contact with the wheels.

Abstract: 1353644 Purifying I C engine exhaust gases; treating charge NISSAN MOTOR CO Ltd 5 May 1971 [2 June 1970 24 Nov 1970(2)] 13115/71 Heading F1B The exhaust gases from an I.C. engine 10 are heated in the exhaust manifold 12, 12a or immediately downsteam of the manifold by hot gas produced by combustion of a fuel and air mixture when the temperature of the exhaust gas or the engine cooling medium, e.g. water, is below a predetermined value. In the embodiment shown a temperature detector and switch 29 on the exhaust pipe 19 closes the circuits of an igniter 22 of a combustion chamber 21 and a valve 27, 27a on a liquefied gas container 25 below the predetermined exhaust temperature and hot gas from the combustion chamber flows through a chamber 20 surrounding the exhaust manifold portion 12a. A portion of the gas discharged from the chamber 20 is mixed with air from a port 34 and flows to the engine intake manifold 11 through a heat insulated passage 32. The passage 32 has a valve 33, 33a which is energized with the valve 27, 27a. Air may be supplied to combustion chamber (42), Fig. 4 (not shown), by a motor-driven blower (51) and the fuel may be supplied by the engine fuel pump (41) through a valve (50, 50a). The blower motor (52) and fuel valve (50. 50a) are energized by the switch 29. The outlet (28'), Fig. 4, (not shown) from the hot gas chamber 20 may be directed towards the air inlet of the engine air filter 15. The hot gas produced in a combustion chamber (55), Fig. 5 (not shown), may be fed into the portion 12a of the manifold. The combustion chamber (55'), Fig. 6 (not shown), may surround the manifold portion 12a and communicate with it through openings in the manifold portion. An afterburner (70) Fig. 7 (not shown), immediately downstream of the manifold 12 may be supplied with air, by a pump (71) driven by the engine, or combustible mixture by a motor-driven blower (84) under the control of a coolant temperature responsive detector and switch (89). The air may be introduced into the engine exhaust passage (17). The exhaust gases and the engine coolant in the region of the intake manifold 11 may be heated by hot gas from respective combustion chambers (101 and 106), Fig. 8 (not shown). The supply of combustible mixture to the coolant combustion chamber (106) is controlled by a valve (107, 107a) which is opened when a coolant temperature detector and switch (108) is closed and the supply of mixture to the exhaust combustion chamber (101) occurs when either the coolant temperature switch or an exhaust gas temperature detector and switch (111) is closed. To prevent engine back-firing air may be fed through a pipe (79), Fig. 7, to the intake manifold 11.
