Title: Improvements in and relating to Platen-operating Mechanism for Typewriting Machines and the like.
IPC: B41J19/76
Filed: 1916-10-26
Abstract: 109,683. Evans, W. E., and Remington Typewriter Co. Oct. 26, 1916. Platen rotation for condensed record work. Operating-mechanism comprising a hand-lever, a pinion, and cams is mounted on an arm pivoted on the platen-carriage, and the cams are arranged so that, on moving the hand-lever, the pinion is engaged with a pinion on the platen shaft, the arc of engagement being greater on the return than on the forward stroke. In the device shown, the operating-mechanism is mounted on a pivot d on a disk or arm c which is pivoted at c<4> to a bracket b and is held up by a spring c'. The operating-mechanism consists of a hand-lever f secured to a pinion e and to a cam g formed with a boss on which is mounted a cam h. The handlever is provided with a pin f<1>, Fig. 9, engaging a spring h<4> in a slot f<2> in the cam h. The cam g is formed with a recess g<5> and the cam h is formed with recesses h<1>, h<2> separated by a projection h<3>.Normally the pinion e is disengaged from the pinion e<4> on the platen shaft b<2> and a pin i on the bracket b lies in the recesses g', h<1> in the position shown in Fig. 3. When the handlever is moved forwards, the lost motion between the pin i and the end< >g<6> of the recess g' is first taken up and the arm c is then depressed to bring the pinions e, e<4> into engagement, the cam h being held back by the pin. In the further forward movement of the hand-lever, the platen is rotated and the cam h is released and is moved forward by the spring h<4> into a position in which the projection h<3> covers the recess g<5>. In the return movement of the hand-lever, the projection h<3> prevents disengagement of the pinions by the spring c' until the recess h<2> is beneath the pin, thus causing the arc of engagement to be greater on the return than on the forward stroke. The hand-lever is secured to the cam g and the pinion c by screws g' passing through slots in the handlever, the arrangement enabling the hand-lever to be adjusted radially for the purpose of varying the amount of lost motion. The forward movement of the hand-lever is limited by the engagement with the pinion e<4> of an adjustable detent e<3>, Fig. 3. on a loose ring e<2> which is, mounted on the pinion c and is secured by the engagement of the detent with the teeth of the pinion.

Filed: 1925-06-16
Abstract: 246,024. British Thomson-Houston Co., Ltd., (General Electric Co.). June 16, 1925. Dynamos and motors combined for transmitting power; systems for alternating-current motors only.-A motor for ship propulsion has stator and rotor windings fed separately by two groups of machines each group comprising an induction generator driven by a prime mover, e.g. an internal-combustion engine, and means for controlling the frequency of the generator, for example a synchronous machine having an adjustabde-speed drive such as from a steam turbine. The running speed of the motor depends upon the sum of the frequencies in the two circuits when the stator and rotor fields rotate in opposite senses and upon the difference of the frequencies when they rotate in the same sense. Either method of speed regulation may be used. Each circuit may comprise a plurality of series connected generators driven by independent Diesel engines, the torque and speed variations in which will have no influence upon the speed of the propeller motors, each machine running at a speed which will enable it to deliver all its available power to the circuit, and hunting and circulating currents being avoided. The exciting machines may be connected in series or in parallel with the generators. The Figure shows a propeller motor 1. The stator 2 is connected through a reversing switch 17 to the stators 13, 14 of two induction generators 3, 4 with their windings in series. The squirrel cage rotors of these are driven by prime movers 5, 6 and exciting current for the generators, and partly for the motor, is supplied at a controlled frequency by the winding 12 of an alternator 7 driven by a steam turbine 8. The rotor 18 of the motor 1 is supplied from a similar group of machines 22, 23, 29 through a reversing switch 19. A switch 20 is provided to connect the rotor 18 to starting resistances 21.
