Title: Improvements in Trolley Heads Employed in Electrical Traction.
Inventor: JAMES HORACE
Filed: 1904-10-08
Granted: 1904-11-10
Abstract: 21,648. James, H., and West, A. Oct. 8. Collectors for overhead conductors. The trolley wheel is so mounted that when on the wire it can readily yield downwards and can swivel to any required extent, but when off the wire it can only swivel through a relatively-small angle out of line with the wire. The frame a mounted on the trolley boom b has a vertical socket c in which the spindle d of the trolley-wheel bracket is pressed upwards by a spring. When the trolley wheel is off the wire, the upward movement of the spindle d is prevented by a pin h engaging a shoulder d<1>, and in this position the swivelling of the spindle is limited by the engagement of projections i on it with the pin h, Fig. 5. In the working position, however, the projections i are below the pin h, and the spindle d can then swivel to an unlimited extent. The bottom of the spindle d rests on a washer j.

Title: Electric Welding Apparatus.
Filed: 1905-02-27
Granted: 1905-12-21
Abstract: 4076. Wise, W. L., [Thomson Electric Welding Co.]. Feb. 27. Welding; working by electricity.-A machine for electrically welding small sizes of iron, brass, german-silver, copper, or other wire is shown in the Figures. The work is held between jaws 37 fixed to slides 12, 13, and jaws 36 fixed to blocks 30, which are mounted on pivots parallel to the line of movement of the slides, are provided with handles 33 and acted on by springs 35 adjustable by means of screws 34. The jaw 37 on the slide 13 is adjusted vertically by means of a wedge 40 and screw 42, and the slide 13 is 'adjusted lcngitudinally on one terminal 6<1> of the transformer secondary 6 by a screw 14. In order that the slide 12 may have free end movement but no vertical nor lateral play, it is provided with angular side-ribs 24 to engage balls 25, dust being excluded from the bearings by plates 28. The ball races 26 are insulated from the table 3, and the slide 12 has fingers 90 projecting into a mercury or other cup in the other terminal of the transformer secondary. The slide 12 is retracted by a lever 18 and bent rod 19, and is advanced by a spring 15 adjustable by means of a screw 17. When the slide 12 has advanced sufficiently to weld the work, an adjustable contact 20 engages a spring contact 21 and closes the circuit through an electro-magnet 73, Fig. 9, which attracts the catch 72 and releases the lever 68, one end of which is pulled away from the contact 70 by a spring, thus breaking the circuit through the transformer primary 7. The closing of the automatic cut-out 69, 70 before the hand-operated switch 70', 76 in the same circuit is effected by the projections 84, 83, Fig. 4, on the lever 68 and rod 77 when the handpressure on the latter is removed and a spring then allowed to withdraw the rod 77 from the flexible part 70<1> of the switch 70', 76. The transformer secondary 6 is threaded through the laminated core 8 and recessed to receive the primary 7. On one leg of the core is a supplemental coil 9 for supplying current to the magnet 73. The primary current is passed through the parts of a sectional reactive coil 49 either in parallel or series by a swicch consisting of contacts 65, 65<1> and bridge-pieces 64 on a longitudinally sliding bar 62, the current being regulated by moving the closed circuit band or conductor 56 and a laminated cylinder which occupies the space within the laminated core 50 of the coil 49.

Title: Improvements in Pistons for Air Suction or Vacuum Brake Cylinders and the like.
Inventor: HARDY JOSEPH ROBERT
Filed: 1905-03-20
Granted: 1905-08-31
Abstract: 5864. Hardy, J. R. March 20. Pistons.-In pistons for vacuumbrake cylinders in which an air passage, governed by, a relief valve, is provided in the piston for effecting connexion between its two. sides when the brakes are off, the air passage and relief valve are so arranged relatively to the rolling packing-ring that, when the piston is slightly raised in applying the brakes, the packing-ring closes all communication between the two sides of the piston. Fig. 1 shows a ball valve 8 in a casing 9 in the piston 3. When air is admitted to the cylinder 1 beneath the piston to apply the brakes, the valve is closed ; when, however, in taking off the brakes, the pressure beneath the piston is reduced, the valve opens and the chambers above and below the piston are put in communication through channels 6, 7. The channel 6 discharges immediately below the npper groove 11, in which the packing-ring 10 enters at the lowest position of the piston, so that, when the piston is lifted, the ring gets below the channel 6 and forms a further protection against the passage of air from the lower to the upper chamber. Fig. 3 shows the valve formed by an india-rubber ring 81, which is fixed in the casing 9 at its outer circumference and closes with its inner free edge the channels 7 in case of excess pressure beneath the piston. In Fig. 4 the casing 9 is shown at the end of the piston-rod, the channel 6 being developed into a pipe leading to the piston wall.

Granted: 1907-02-28
Abstract: 5435. Marriott, T. March 6. Pitch.-Disintegrated peat, peat dust, or peat moss dust is combined with rich or soft pitch or with ordinary medium or hard pitch and tar or anthracene oil or heavy tar oils, the product being sufficiently bard and brittle for pulverizing for use in making fuel briquettes. The dry peat may be added to boiling pitch as it issues from the still, the period of distillation being reduced by onetenth or more, this corresponding to the attainment of a temperature of about 280‹ C. Any deficiency of tar or anthracene oil due to the quality of crude tar employed or to excessive distillation may be made up by addition to the mixer. Instead of employing soft pitch, peat may be mixed with tar or anthracene oil and then under heat with ordinary medium or hard pitch. Addition of melted medium pitch to the soft pitch and peat is advantageous.

Title: Improvements in Apparatus for Starting and Regulating Electric Motors.
Inventor: FRICKER GUY CAREY
Filed: 1906-06-14
Granted: 1907-06-13
Abstract: 13,673. Fricker, G. C. June 14. Switches.-Resistance is cut into or out of the armature circuit of an electric motor by means of a rheostat, the arm of which is moved in either direction by tho preponderating magnetic effect of one or other of two differentially-opetating solenoids. One solenoid is connected in series and the other in shunt with the armature, the speed of which determines the relative strengths of the coils. In Fig. 2, the upper solenoid b is shown placed across the terminals of the armature f, the main current through which passes through a rheostat e and a lower solenoid a. Current passes between the rheostat and the lower solenoid by means of a conducting core h bearing the contacts i and connected to the solenoid a. In the starting position, the core h common to both solenoids is in its lowest position, with its multiple contacts i pressed outwards by springs k against the inside of the lowest insulated ring contact d of the rheostat. As the motor speeds up, the current through the solenoid a weakens, and the upper or shunt solenoid pulls the core upwards, cutting out the resistances. A guiding rod or wire may paps through the centre of the core, this being made tubular to contain the rod. The latter may also engage electrically with the core by means of multiple contacts on the core itself, so as to receive current from the rheostat whatever the position of the core, and to pass the current on to the solenoid a, which is electrically connected to the bottom of the rod. The core may be retarded in its movement by a dash-pot, spring, or weight. In a modification, the solenoid a is above the solenoid b, and the core is connected to one end of a pivoted lever, the other end of which holds a vessel containing mercury. The mercury is raised to cover the ends of a series of rods depending from and connected to the resistances. In the application of the invention to a series motor, as shown in Fig. 5, the cores h, h<1> of the series and shunt solenoids respectively, act on the opposite ends of pivoted bar v biased to the 'off' position by a weight x. An arm w on the bar is moved by the solenoids over a row of resistance terminals. Contact with the resistance terminals may be made by means of spring-pressed conducting-rollers, as described in Specification No. 14,589, A.D. 1906.
