Title: Improvements in Hardening and Tempering Metals.
Inventor: BOULT ALFRED JULIUS
Filed: 1901-07-29
Granted: 1902-06-19
Abstract: 15,342. Boult, A. J., [Miskolczy, J.]. July 29. Tempering.-Steel or the like is hardened and tempered during the sudden impact of an artificially-cooled body upon the metal, which has previously been heated to a dull cherry-red heat. The metal to be treated is held between spring jaws g, in an airtight chamber A, which may have a glass cover. Near each side of the metal is a hollow head C, secured to a sliding rod B and fixed to a piston D<2>, within a cylinder D. Each rod B is formed with two longitudinal passages b, b<2> respectively communicating with the chambers e, e<2> of a box E to which a cooling-fluid, such as compressed air or gas, or liquid air, is supplied from a pipe e<3> ; the cooling-agent flows along the passage b into the head C, and back along the passage b', thus cooling the end c' of the head. The metal may be heated by means of an electric circuit h, and, when the desired temperature bas been reached, the heads C are simultaneously forced against the metal. If desired, the heating and cooling of the metal may take place in vacuo. Before the impact, the ends c' of the heads are damp in consequence of the condensation of vapour from the air upon the cold metal.

Title: Improvements in Electric Railways and Tramways with Motor Driven Collectors in a Closed Conduit.
Inventor: JANECEK FRANZ
Filed: 1901-10-01
Granted: 1901-11-23
Abstract: 19,538. Janecek, F. Oct. 1. Electric railways and tramways with motordriven collectors running inside a closed conduit. Continuous or polyphase currents may be used for the motors on the vehicle, but the collector is driven by polyphase currents. Conduits ; conductors; collectors.-Connected sectional conductors C, C<1> are mounted on the insulating removable cover b of the conduit a, which contains one or more channelsection main conductors e supported on insulators d. A twoaxled truck, with series-connected motors m, m<1> on each axle, runs on these conductors e, and carries brushes B or D, E for transmitting the main continuous or polyphase current to the vehicle, and also brushes f, g for picking up two of the phases of the current which drives the truck, the third being taken by the brush B. The vehicle has main collectors B<1> or D<1>, E<1>, and also brushes h, i, h<1>, i<1>, bearing on the exposed conductor sections. The brushes h, i, h<1>, i<1> are connected so that their phases are in opposition, and thus, whatever the direction of the vehicle, the truck cannot overrun it, because the front pair supplies current that drives it back. The brush B' is made long enough for this purpose, and the truck motors are constructed so that its speed is slightly greater than that of the vehicle, so that it remains between the brushes.

Title: Improvements in Automatic Filling, Replenishing Mechanism for Looms for Weaving
Filed: 1904-02-11
Granted: 1905-01-12
Abstract: 3376. British Northrop Loom Co., [Northrop Loom Co.]. Feb. 11. Loom shuttles, changing bobbins in, automatically; guards -Consists of means for rotating the circular bobbin-magazines of automatic looms, such as the Northrop loom, positively and without shock, when a fresh supply of weft is required to be inserted into the shuttle. The invention is described as applied to the Northrop loom. The feeder or magazine a' is constructed and mounted in the usual manner, and has secured to it a ratchet-wheel a<8> having teeth corresponding in number to the number of bobbins b carried by the magazine. The transferrer f<1> is operated in the usual manner, and is provided on one side with a recess within which is pivoted a tubular dog d<20> containing a plunger d<25>, which is pressed outwards by a spring. An upturned lug d<22> of an ear formed on the dog d<20> is pressed against by a spring- controlled plunger f<32> mounted within a tubular housing f<31> formed on the transferrer. When the transferrer f<1> is in its inoperative position, the plunger a<25> is held in engagement with the ratchet-wheel a<8>, as shown, by the combined action of its spring and the plunger f<32>. When the transferrer is operated upon to insert a fresh bobbin into the shuttle S, the dog d<20> is lowered with the transferrer, and the head of the plunger d<25> clicks over the last tooth, and is forced by the action of the plunger f<32> into the next tooth of the ratchet-wheel a<8>. When the transferrer is returned, the plunger d<25> moves the ratchet-wheel a<8> one tooth, thus bringing the next bobbin b against the usual guide h<1>, and, since the plunger d<25> is yieldingly mounted, the movement is effected without shock. A rigid upturned stop f<35> formed on the transferrer prevents additional movement of the magazine, and backward movement is prevented by a detent pawl e<25>, which is pivoted on a stud e<30> on the magazine stand A<7> and is controlled by a spring. If it is required to rotate the magazine backwards, the pawl e<25> is drawn back by hand, and a lateral extension on the end of an arm e<28> formed on the pawl acts upon the dog d<20> and withdraws the plunger d<25> from the ratchetwheel a<8>. When it is desired to depress the transferrer manually, injury to the operative's hand is prevented by its coming against a guard consisting of a lateral extension f<10> of an upturned part f<9> of a fixed arm f<6>. The depression of the transferrer is then sufficient for the stop f<35> to be moved below the teeth of the ratchet-wheel a<8>.
