Title: Improvements in Railway and Tramway Vehicles Driven by Electricity.
Inventor: FEENY VICTOR ISIDORE
Filed: 1901-05-30
Granted: 1901-08-03
Abstract: 11,168. Feeny, V. I., [Allgemeine Elektricitõts-Ges.]. May 30. Electric locomotives and motor vehicles.-Relates to the support of the motors and to resilient driving-couplings for electrically-propelled railway and tramway vehicles. Fig. 1 shows a front view, and Fig. 2 a side view, of the motor suspension arrangement. The motor within the casing a is arranged on a hollow shaft b, through which passes the axle of the driving-wheels d. The motor casing is secured to a frame g supported by springs f carried on the axle-box above the vehicle springs i. The frame 9 is furnished with shoes p resting on the springs f and curved so that, as the shoes deflect, the points of support approach the centre of the springs, and the greater the shock the stiffer the springs become. The shoes may be adjusted to compensate for a weakened spring. The motor casing is constrained to move vertically with regard to the undercarriage k by slideways, and the rotational recoil is resisted by rods l. The hollow motor shaft b is resiliently coupled to the wheels d, as shown in Fig. 6, by radial laminated springs s held by a ring t made in several parts, each holding a pair of springs. Soft metal bushes are provided at each end of the shaft b to prevent damage in case of failure of the spring suspension.

Granted: 1902-04-24
Abstract: 12,115. Hannah, J. D., and Walton, J. June 13. Ports.-To allow of the gun and other ports and portholes of war-ships and other vessels being readily closed or nearly closed, a series of curved plates A, Fig. 2, are pivoted between a rotary cylindrical frame C and a fixed slotted plate E. Each plate A is pivoted by a projecting pin B' to the frame C, and has a pin B projecting from the opposite side of the plate and engaging with a more or less tangential slot D in the plate E. Thus, if the plate E be fixed within the porthole and the frame C be turned to the left by means of the rack G and the toothed segment F, the port is closed, the movement of the pins B along the slots D causing those ends of the plates A to travel towards the centre of the opening. When the rack is released, the frame may be returned to its original position by a spring, or the opening and closing movement may be effected by hydraulic, electric, or other power.

Title: Improved Combination of Electric Motors for Starting and Operating them.
Inventor: BURKE JAMES
Filed: 1901-09-02
Granted: 1901-10-12
Abstract: 17,567. Burke, J. Sept. 2. Electric locomotives and motor vehicles.-To enable electric motors (especially large motors for electric railway cars &c.) to be started without causing a rush of current to the armature, and with a relatively large torque, a combination of a shunt motor and a series motor is employed, in which the two armatures are mounted on a common shaft or on separate shafts coupled together. At starting, the two armatures a and b and the series winding d are connected together in series, while the shunt winding c is preferably connected directly across the mains; a starting and regulating resistance f and a variable shunt resistance k are connected in circuit, as shown. As the speed increases, the armature a exercises a braking effect on the armature b ; this is gradually reduced by increasing the resistance k, until finally this resistance is cut out. The speed is further increased by cutting out the resistance f. In the next place, a variable resistance is inserted between the line and the shunt winding c, and the armature a is short circuited. Further increases of speed are obtained by connecting the motors in parallel, a resistance being first arranged in circuit with the armature a, then a resistance in shunt to the field winding d, and finally a resistance in series with the field winding c. During stopping, the armature a of the shunt motor acts as a magnetic brake.
