Abstract: 16,579. Hulbert, C. E. Lacy-. July 25. Compressing; ex- hausting. - An air or gas compressor or exhauster i s constructed with two cylinders a, b, Fig. 1, fixed to- gether or forming one casting, and arranged on oppo- site sides of a crank shaft q. The inner ends of the cylinders open into a crank chamber o, the covers of which support the crank-shaft bearings. The pistons c, d of the two cylinders are rigidly connected by rods g, g, and one of them is connected to the crank shaft by a rod r. The pistons and the end covers are fitted with valves consisting of steel discs l resting on perforated seats and rising against stops m. In the case of a compressor, the valves in the pistons act as suction valves, and the valves in the covers as delivery valves delivering into chambers k. When the apparatus is arranged as an exhauster, the valve in the piston acts as a delivery valve, and the valve in the cover as a suction valve as shown in Fig. 3. In each case the valve-stop which comes inside the cylinder is arranged to enter the valve port opposite, and thus reduce the clearance. The crank chamber is fitted with a silencer consisting of a box s, Fig. 2, with wooden or other baffles t, t, or a number of small tubes. The crank shaft may be driven directly by an engine or by pulleys. The cylinders and crank chamber may have a water jacket v.

Title: Improvements in or connected with Alternate Current Motors.
Inventor: FYNN VALERE ALFRED
Filed: 1902-09-20
Granted: 1903-09-19
Abstract: 20,572. Fynn, V. A. Sept. 20. Motors, controlling.-Relates to the arrangement of a single-phase motor, which will start with considerable torque. The motor is of the asynchronous type, the stator carrying one winding only, preferably embedded in partly-open slots. The rotor is formed with the coils or bars all electrically connected at one end, and at the other connected to the segments of a commutator. Brushes, covering two or three segments each, are placed on the commutator, and are connected directly or through an impedance or capacity. The brushes are placed at an angle at starting. The sections of the commutator are connected by resistances or bridges, as shown at 0 in the Figure, to eliminate sparking and to increase the power of the motor when near the synchronous speed, The brushes may cover as much as 45‹ of the commutator, or a. number of narrow brushes may be employed. When the motor has speeded up, the brushes may be lifted off the commutator automatically or by hand, the segments of the commutator being first short-circuited. By using two or more sets of interconnected brushes when the motor is running, or by altering the relative position of the sets, the speed can be varied. A transformer of the ordinary or " auto" type, which may be " stepped," may be employed for supplying the stator with a higher or lower potential. In multipolar machines, two sets of brushes for each pair of poles may be employed.

Title: Improvements connected with Type Composing Machines.
Inventor: HADDON WALTER
Filed: 1903-06-29
Granted: 1904-05-12
Abstract: 14,447. Haddon, W., [trading as Haddan & Co., J.], and Larder, F. T. June 29. Type, setting.-Relates to means connected with composing-machines for indicating the length of the line being composed, for placing the lines in a galley, and for leading between the lines. Fig. 2 shows a side elevation in which the types, as they are composed, are fed along a channel A<1> formed between a sliding-plunger B, and a support D. As the line is formed, it is supported by, and moves, a finger E<1> on a slide E, guided on transverse rods E', and pulled towards the incoming types by a cord and weight E'. When the slide E reaches a predetermined position, it engages a stop-piece adjustably fixed on a longitudinally-movable bar F, one end of which is engaged by a bell-crank lever F' connected by a rod F<3> to a pivoted toothedsegment F<4>, in gear with a pinion on a pointer G', which moves over a scale G. The segment is moved in one direction by a spring F<8>. When the operator has completed the line by filling in at the end of the spaces required for justification, it is pushed into the galley H by the plunger B, moved forwards by two cams J<2> engaging extensions B' of the plunger. The plunger is returned by a spring. The shaft J of the cams J<2> is driven, through a clutch, by worm gear from a shaft rotated by the composing-machine. The clutch is operated by a special key on the machine. The line-support D is carried by pivoted arms D', and is raised by a spring to permit the types to pass into the galley. It is held in the normal position shown, by a pivoted catch D<4> operated to release the plunger by the rod F. The support D is depressed to its normal position, as the plunger advances, by a rod M connected to the plunger and to an arm M', which engages one of the arms D'. The support, being thus lowered behind the types, prevents them from adhering to and returning with the plunger. Leads may be inserted between the lines, by a plunger-blade N<1>, which presses the leads from a magazine N down into the line channel. The blade N<1> acts as a stop for the leads in the magazine and has a 'rib or shoulder for engaging the upper edge of the front lead. It is carried by arms N<4> raised by a spring N<7> and depressed by means of an arm on the shaft N<5> having a pin, which may be caused to engage a grooved cam when desired, by operating a special key. Fig. 9 shows a plan view of an indicator applied to a curved type channel A', into which the types are fed in the direction indicated by the arrow. The indicator scale G' and pointer G<4> &c. are carried by a frame G<5> pivoted at G<6> and adjustably fixed in position by means of a screw G<8> and graduated scale P. The types engage and move a finger E" on an arm E<8> fixed to a sleeve E<7> on the stud G<6>. The arm E<8> engages and moves a sliding rack G<11> gearing with a pinion on the pointer G<4>. The sleeve E<7> may be raised to lift the finger E<13> out of the channel A', by an arm E<9> operated by a key when desired.
