Title: Improvements in engine starting mechanism
IPC: F02N99/00
Filed: 1931-09-03
Abstract: 389,128. Turning-gear. ECLIPSE AVIATION CORPORATION, 545, North Arlington Avenue, East Orange, New Jersey, U.S.A. Sept. 3, 1931, No. 24745. Convention date, Jan. 7. [Class 7 (v).] In an engine starter of the inertia type, centrifugally operated means are held in retracted position while the flywheel 35 is being set in rotation and are adapted, when released, to move radially into engagement with an engine member 11 and to maintain the engine member and flywheel coupled after the engine has been started, so long as the flywheel speed exceeds a predetermined value. As shown, the starter flywheel 35 is housed in a casing 11, 12, 13 mounted upon the engine member 5, which may be the engine flywheel. The web 36 of the starter flywheel is connected by a friction clutch 39, 40 to a hub member 41, 55 keyed to a shaft 66 and rotating on ball bearings 62 carried by a transverse plate 59 forming part of the casing section 12. The hub member 41, 55 is secured to the flange 50 of a shaft 33 integral with a sun gear 21, and planet wheels 26 meshing with the gear 21 and with an internal gear 27 on the casing 12, 13 are carried by the flange 18 of a rotatable sleeve 17. The flywheel 35 is set in rotation by a hand crank 4 engaging a cross pin 32 in the sleeve 17 and driving the shaft 33 and the flywheel 35 through the planetary gearing. The centrifugally operated means transmitting the rotation of the flywheel 35 to the engine consists of shoes 60, 61 pivoted at 82, 83 on the flange 65 of the shaft 66 and provided with friction plates 64. The shoes are normally held out of engagement with the casing member 11 by springs 80, 81 and by the engagement of lugs 69 on the shoes with a cup-shaped member 71 on the end of a rod 73 passing axially through the flywheel and gearing. When the flywheel has been set in rotation, a stud 75 on the rod 73 is depressed against a spring 76 to release the lugs 69, and the shoes move outwards under centrifugal action into engagement with the casing member 11 and transmit their energy of rotation to the engine. If the engine backfires, the shoes 60, 61 are withdrawn from the member 11 by the springs 80, 81 and the lugs 69 are reengaged by the member 71 on the release of the stud 75 on the rod 73. During normal running, the flywheel 35 and its casing rotate with the engine shaft and the momentum of the flywheel may be used for restarting In a modification, the friction coupling 39, 40 is omitted and the flywheel is mounted directly on the hub member 55. In another form, the stud 75 on the rod 73 forms a cap extending over the sleeve 17 to exclude moisture, and the cross-pin 32 is replaced by externally projecting pins for engagement by the hub of a cranking handle.

Patent GB-1423119-A (GB)
Title: Valve
IPC: F16K11/048
Filed: 1974-06-05
Abstract: 1423119 Valves S RYDBERG 5 June 1974 [8 June 1973 25 Sept 1973] 24934/74 Heading F2V A valve arranged to direct first and second pressure fluids entering a housing 1 through respective inlets 6, 7 alternately to an outlet 22 comprises chambers 8, 9 communicating with the respective inlets, and flexible closure members 3, 3<SP>1</SP> carried by an axially slidable spindle 2 and co-operating with seats 4, 5 to alternately communicate chambers 8, 9 with passage 21 and outlet 22. Spindle 2 is actuated by a diaphragm 12 subject on its left side to the pressure in chamber 9 and on its right side to that in a control chamber 11. The latter communicates with chamber 8 through passages 13, 14 having respective variable restrictions 17, 18 and nonreturn valves 16, 15. Thus in the position shown fluid, e.g. hot water, supplied to inlet 7 can flow past closure 3<SP>1</SP> to outlet 22, whereas closure 3 blocks flow therepast of cold water supplied to inlet 6. However the cold water flows through passage 13 to control chamber 11 until the pressure therein is sufficient to move diaphragm 12 leftwards to seat closure 3<SP>1</SP> and open closure 3, whereupon cold water flows to outlet 22. The pressure in control chamber 11 will now decrease as the water therein vents through passage 14 to chamber 8 until diaphragm 12 moves rightwards to seat closure 3 and open closure 3<SP>1</SP>, thus completing a cycle. Control chamber 11 communicates via orifice 19 with an accumulator chamber 20 containing air or rubber. The timing of the valve movements can be altered by adjusting restrictions 17, 18, which may be temperature responsive. In a modification (Fig. 3, not shown) a partition (36) divides the outlet into two separate passages (22<SP>1</SP>, 22<SP>11</SP>) so that the two fluids do not mix. A flexible diaphragm (35) seals partition (36) to spindle 2. In a further modification (Figs. 4, 5, not shown) the controlling fluid flows in a closed circuit separate from the controlled fluids and is acted on by an additional diaphragm (26) exposed to pressure in chamber 8. The fluids may be gaseous rather than liquid.

Abstract: 482,112. Typewriters. FAIRWEATHER, W. C. (Underwood Elliott Fisher Co.) Sept. 14, 1937, No. 24955. [Class 100 (iv)] Paper-supports; platen-roller brakes; linespacing mechanism.-A detachable platen, associated with a line-spacing detent, and a brake which is effective when the detent is released and vice versa, is retained in open bearings in the carriage by means of pivoted clamps adapted to force the platen firmly into position against the pressure of either the detent or brake. The platen 15 shown in Figs. 1 and 2 is provided with stub-shafts 21 which pass through hubs 22, 37 on the enddiscs 18, the hub 22 and the right-hand stubshaft being mounted in bearings 40 which are received by slots 42 in the end-plates 10 of the platen-carriage. Each bearing is retained by a keeper 47 consisting of a pivoted yoke 55 provided with a screw 57 having a large head 61 engaging the bearing. A link 48 connects the yoke to a finger-lever 46 which is raised to release the keeper. The link and fingerlever form a toggle which normally locks the keeper. Accidental movement of the fmgerlever is prevented by co-operation of a spring- urged locking-sleeve 67 with a hole in the finger-lever. When the locking-sleeves are pulled outwards, the finger-levers can be raised to release the keepers and thereby permit detachment of the platen. On return of the finger-levers, the locking-sleeves are cammed outwards, and then return automatically into locking position. The line-spacing wheel 25 co-operates with a pawl 83 formed on a pivoted arm 28 carried by a pivoted arm 27 operated by the line-spacing lever, the arms 27, 28 being arranged below the left-hand stub-shaft 21, so as to permit detachment of the platen. Overthrow of the pawl is prevented by cooperation of a pin on the arm 28 with a nose on the arm 27. Line-spacing is regulated by means of a finger-lever 87 having a pin 86 co-operating with the pawl. The linespacing wheel co-operates with a detentroller 98 carried by a pivoted arm 99 having a finger 102 abutting on a spring 100 which is mounted on a bracket 101 and is provided with an adjusting-screw 101a. The detentroller is releasable by depressing a fingerlever 106 in connection with a link 108 having a slot 101 engaging a pin 110 on the arm 99. A coupling for the line-spacing wheel comprises a brake-shoe 32 which co-operates with a drum 30 on the line-spacing wheel. When the detent-roller is released, a brakespring 103, secured to a bracket 104 on the arm 99, is pressed against the drum 30, to prevent accidental movement of the platen. The spring 103 may be provided with a frictioncoating.
