Granted: 1903-12-17
Abstract: 2538. Smith, H., Smith, O., and Hayward, T. A. Feb. 3. Bending; straightening.- Relates to means for bending, straightening, and setting the flanges of angle, channel, Z, bulb, T, and other beams and bars, used in shipbuilding &c. The bar or beam to be treated is pressed between a pair of flexible forms, which are set to the required shape or curve. Fig. 1 shows a plan and Fig. 2 a cross-section of the machine ; Fig. 6 shows, to a larger scale, a cross-section of the machine as used to treat a Z-beam. The form A is stationary, and consists of a number of blocks hinged together at a, and adjustable by means of screws D. Each block contains a number of separate pieces G, which can be adjusted to the desired curve by means of screws J and levers H, Fig. 3. Each piece G has an adjustable screwed block G' to give the desired inclination to the flanges of the bar or beam. The form A<1> is constructed similarly to A, and is shown as moved by hydraulic cylinders, but electric or other power may be substituted. A single bar, or a pair, placed back to back, may be treated at each operation. The bar is placed on a bed C composed of hinged blocks, and the upper flexible beam C is then pressed down bv hydraulic power to prevent lateral movement of the bar to be bent. The for n A' is then pressed forward to bend the beam to shape. An arrangement of toggle-links L, L<1>, L<2>, actuated by an adjustable stop K, is used to bend the end of the bar sharply. At the lower end of Fig. 1 is shown a toggle arrangement for bending bars to a right-angle.

Granted: 1904-02-11
Abstract: 21,893. Hewitt, H. Oct. 12. Safety suspending-apparatus for mine or cage lifts. The blocks A, which slide on the guideropes, carry the pivoted levers C which are also pivoted to the upright D, the springs S attached to the levers being kept in tension by the chains E connected to the hauling- chain G. The blocks A rest upon and are separate from the stays L, so that, should the hauling- chain break, the springs cause the cam end of the levers to press the rope against the block, thus suspending the cage. The weight of the cage acting through the uprights D further increases the pressure of the cam ends on the ropes.

Title: Improvements in Starting Resistances for Electric Motors

Granted: 1905-06-15
Abstract: 16,664. British Thomson - Houston Co., [General Electric Co.]. July 28. Motors, controlling.-In an alternating-current induction motor, a number of resistance bobbins connected in series with the rotor coils are mounted on the rotor with their axes parallel to the rotor shaft, and axially - moving contacts, operated from without the motor, make sliding contact with these coils. The bobbins B, B are wound non-inductively with insulated resistance material in the form of thin strip, and are secured to the rotor by bolts b, while a ring b<1> clamped against the outer ends of the bobbins takes up the centrifugal strain. The rotor shaft A is hollow for part of its length, and receives a rod C carrying a pin c which extends outward through the slot D in the hollow shaft and carries a collar E. This collar carries brushes e electrically connected together, one bearing on the outer surface of each of the bobbins. When the rod C is pushed inwards, the brushes e travel over the surfaces of the bobbins, and so lessen the amount of resistance in the rotor circuit. Fig. 3 shows the connections diagrammatically for a three-phase motor. Each phase of the motor has connected in series with it a bobbin, by means of the terminal b<2>. To hold the brushes in a given position and to prevent them from being moved too rapidly by hand, a rack F is secured to the shaft D, and is engaged by the spring-pressed pawl f carried by the collar E, giving a step-by-step movement to the collar when pushed in or pulled out by the rod C.

When a revolving disc is employed to impart the drag, it is supported between curved springs secured to the parts a, b which may be provided with fine screw threads as before, or as shown in Fig. 8, in which the disc o is shown supported between springs p on separate rings r and the part b provided with pins engaging a spiral groove in the part a. Fig. 11 shows a modification, the part b entering the part a, which is provided with spiral grooves w to receive projections on the part b. The weight of the part b is varied to regulate the drag. A cushion of air may replace the springs p.

Granted: 1906-08-02
Abstract: 20,431. Snell, F. A. Oct. 10. Water and other liquid pressure engines. - Hydraulic engines for air or gas compressors used for increasing the pressure of air or gas supplied to incandescent burners are provided with a speciallyarranged and unpacked pilot valve for actuating and guiding the main valve of the motor, the valve being of the type in which the pilot valve slides within the main valve. In order to reduce friction, packing is dispensed with, wherever possible. Fig. 2 shows a sectional view of the apparatus. The hydraulic motor A is alined .with the compressor B, the piston-rod carrying a projection j which engages collars i on the rod, the hollow upper portion of which forms the pilot valve g controlling the action of the main valve e. Fluid enters the main valve casing at the chamber a and is exhausted from the chamber b. The chamber c is alternately placed in communication with the chambers a, b, and is always in communication by a pipe d' with the top of the piston, the smaller underside of which is constantly exposed to fluid pressure. By means of the ports h, h<1>, h<2>, the space k above the main valve is opened to pressure or exhaust, thus causing movement of the piston m attached to the valve e. Fig. 4 shows a modification in which the parts are inverted, and the adjustable part of the main valve seat is formed in the valve instead of on the seating as shown in Fig.2.
