Title: Improvements in Point Changing Mechanism for Railways and the like, of the Type Actuated from a Vehicle on the Track.
Inventor: PESTALOZZA PAOLO
IPC: B61L11/02
Filed: 1911-11-21
Granted: 1912-07-25
Abstract: 26,028. Pestalozza, P. July 26, [Convention date]. Mechanically operated from vehicle; spring control; transmitting - mechanism, applicable generally.-At a suitable distance from the points, a bell-crank lever 1, Fig. 2, is mounted so as to engage a stud 12 in the rail groove. This bell-crank is normally kept in its lowered position by a catch 6 against the action of a spring 27, Figs. 15 and 16. When it is desired to operate the points, an auxiliary wheel on the vehicle is caused to engage the stud 9<1>, which withdraws the catch 6 and allows the bell-crank to force the stud 12 into its operative position. The first vehicle wheel then depresses the stud 12, which, through the rod 4, causes the reciprocation of a rod 26 pivotally connected at 21<1> to a casing 21, Fig. 10, loosely mounted on a spindle 22. The casing carries pawls adapted to engage a four - toothed ratchet - wheel 31 carried loosely on the spindle 22 but rigidly connected to a cross or four-armed star-wheel 33. The parts are so adjusted that each depression of the bell-crank 1, Fig. 2, causes the cross to rotate through a quarter-revolution and by its alternate engagement with the projections 34<1>, 34<11> throws the points alternately to their opposite positions. The cross is prevented from moving backwards by another pawl 39 engaging a wheel fixed on the spindle 22. A modified construction is described in which the cross has only two arms. The points may also be operated independently by hand. Spring control.-The completion of the movement of the points in either direction is effected by the spring-pressed rollers 44 acting on the double wedge-shaped member 45. The levers carrying the rollers are mounted on pins 42 between cones 42<1> which permit the levers to make slight vertical movements.

Patent GB-191207853-A (GB)
Title: Improvements in or relating to the Breech Actuating Mechanism of Semi-automatic and Quick Firing Guns.
Inventor: SCHNEIDER EUGENE
IPC: F41A5/32
Filed: 1912-04-01
Granted: 1912-12-12
Abstract: 7853. Schneider, E. April 1. Ordnance breech mechanism.-Relates to semi-automatic wedge breech mechanism in which the breech block is moved into closed position by a helical torsion spring stressed during recoil, and consists in coiling the spring round a longitudinally-arranged shaft, gearing with the breech-operating lever, and adapted to be rotated on recoil to open the breech and stress the closing-spring by a device interposed between the shaft and the cradle. Fig. 1 is a longitudinal vertical section, and Fig. 4 an enlarged rear elevation, of the mechanism. The wedge breech block a carries a boss a<1> engaging a slot b<1> in the lever b, which is pivoted at b<2> and has a toothed sector b<3> gearing with a similar sector i on the shaft d. Round this shaft is coiled a spring g, one end of which is fixed to the bearing c and the other to a ring h on the shaft d. As the gun recoils, a transverse pin on the shaft d engages an incline k<1> on the cradle, and the consequent rotation of the shaft rotates the lever b to open the breech, and also stresses the spring g. Towards the end of the recoil, a nose on the breech-block a strikes a nose on the extractor n and rotates it to eject the cartridge case. A spring-bolt a is thereby released and. engaging a shoulder on the breech block, retains this open until the bolt is lifted by the extractor when a cartridge is loaded into the gun. The block thus liberated moves into the closed position under the influence of the spring g. To prevent damage to the mechanism should the breech block become wedged, the pin which rides on the incline k<1> is fixed to a sleeve j' having teeth q held by a strong spring r in engagement with teeth p on a sleeve d' keyed to the shaft d. If wedging occurs, the shaft d remains stationary, but the pin can turn, the teeth q sliding on the teeth p and compressing the spring r. To enable the breech to be handoperated, the sector i is carried by a sleeve s, the teeth s<1> of which are pressed into engagement with teeth t' on the shaft d by a spring t. The sectors i, b<3> are disengaged by retracting the sleeve s until the teeth s<1> are out of gear, rotating the sector i into the dotted line position, Fig. 4, and allowing the teeth s<1> and t' to re-engage. A wedge u is provided to render the bolt o inoperative if necessary.

Title: Improvements in Liquid Fuel-fired Steam Generators.
Inventor: LAING ANDREW
IPC: F23C99/00
Filed: 1913-10-16
Granted: 1914-10-08
Abstract: 23,459. Laing, A. Oct. 16. Liquid-fuel furnaces.-In a lighting-up device for liquid-fuel steam-generator furnaces, of the kind in which a preheating-tube for the oil supplied to the lighting-up burner is exposed to the flame from the burner, the temperature of the oil fed to the burner is regulated by arranging the preheating-tube so that it is capable of varying projection into the furnace. Prior to lighting up, the ordinary connecting-pipe between the distributing-box g, Fig. 1, and the burner is uncoupled, and in place of the ordinary burner, a burner used particularly for lighting up may be employed. The preheating-tube a, Fig. 2, which is preferably of the Field-tube type, is interposed between the distributing-box g and the lighting-up burner, flexible connexions d, f being used for coupling up. A piece of waste soaked in paraffin is placed upon the ring m and ignited to heat the tube a. When the temperature of the tube a has been raised sufficiently, a torch is inserted through the opening k in the furnace front, and the valve g', controlling the supply of oil under pressure produced by a hand pump is opened slowly. The burner is thus ignited, and the temperature of the fuel is adjusted by sliding the tube a in its support into or out of the furnace. When sufficient steam pressure has been obtained in the boiler, the burner is coupled directly to the distributing-box. When there is a battery of boilers, the above-described apparatus is used to raise steam in one boiler only, after which the steam can be used for raising the oil fuel to the necessary temperature for use in the other boiler furnaces.
