Patent GB-189923309-A (GB)
Title: Improvements in Acetylene Gas Generators.
Inventor: SMITH GEORGE GREGORY
Filed: 1899-11-22
Granted: 1900-01-06
Abstract: 23,309. Smith, G. G. Nov. 22. Acetylene.-A number of generators C, each having its own water supply tank E, are brought into operation successively and automatically. Each generator receives enough water from its tank to decompose all the carbide therein, and liberates enough acetylene exactly to fill the gas holder A, which is common to all the generators. Each time the bell of the holder falls, another generator is automatically put into operation. At any time a used generator can be cleaned out and recharged without affecting the one in action. Each generator has a removable bottom plate 3 secured by a bow 4 and clamping-screw 5. The carbide is contained in a cylindrical holder G, centered in position by flanges 7, and provided with a central collapsable perforated tube throughout its length. It is supported by a spring 8 just above a spike 6, while a second spike is held by a spring 15 just above the centre of the top. When the spindle 9 is forced downwards, the top spike pierces the carbide holder above the central tube, and the whole holder is depressed upon the lower spike, whereby that end is also pierced, while at the same time the water is turned on. To perform these operations, a shaft 25 is rotated by a falling weight 35, when the bell falls sufficiently to allow the trip-lug 31 thereon to trip the pawl 29 of the ratchet-wheel 27. On the shaft 25 are a number of striker arms 33, one for each generator, radially disposed around the shaft at equal angles. One of these then strikes the cam surface 36 of one of the spindles 9, and forces it downwards, thereby not only causing the carbide receptacle to be pierced, but also, by means of the pin 20, lever 22, and cock lever 23, causing the stop cock 19 on the water delivery pipe to be turned on to the same generator. To prevent all the generators from being started at once should the pawl and ratchet mechanism fail, a protecting-cap 38 is placed over each spindle 9, so that the striker can only operate the spindle after this cap has been moved on one side. This is done by means of a second shaft 41, having mounted thereon a crownwheel 42 and a disc 46 with recesses into which the end of a spring lever can rest. A finger 47 on the bell turns the crown-wheel one step forwards on each descent, whereupon one of the striker arms 43 mounted on the shaft 41 turns the corresponding cap on one side. A drain cock 53 is connected by rods 51, 52, 54 to the water cock 19 in such a manner that the cock 53 is always open to allow any leakage to escape when the cock 19 is closed, but is closed as soon as that one is opened. The gas passes by a valve 56 and pipe 55 to the holder A. Within the holder there is a layer of oil 57 to prevent the gas from being moistened by contact with the water surface. Instead of the arrangement shown, the spindle 9 may be depressed by cams, and returned by weighted levers.
Patent GB-189924430-A (GB)
Title: Improvements in Screwing Dies for Lathes or other Machines.
Inventor: ERRINGTON FRANKLIN ALFRED
Filed: 1899-12-08
Granted: 1900-01-27
Abstract: 24,430. Errington, F. A. Dec. 8. Screwing; tools.-A screwing-die for a lathe or other machine is adapted to open and close by coaction with the work. The body 1 has a shank 3 for attachment to a live spiudle or a turret head. Abutments 2 on the body act as guides for an axially-movable die-holder 7, having slideways 7<d> to receive radially-movable chasing-dies 8. The radial position of the dies is determined by wedges 4 engaging the abutments 2, and adjusted by screws 1<b>. The screws have round heads engaging T-slots 4<a> in the wedges, and have slits 1<x> to allow them to be turned by a screwdriver and to form a spring locking-end. The dies have thrust-surfaces 13, 14 bearing against corresponding surfaces 10, 11 on the wedges, and are normally pressed outwards by a spring 9. The length of thread cut may be automatically determined by an adjustable stop 5, which engages the end of the work and causes the die-holder 7 to be drawn axially outwards so that the surfaces 14 slide off the surfaces 10, 11, allowiog the dies to spring outwards and disengage the work. The dies are closed by applying pressure to them or the die-holder by means of the work or other suitable means, which causes the die-holder to move axially inwards and the dies to be moved radially inwards by cam surfaces 12, 13. The inward movement of the die-holder is limited by lateral projections on the wedges. The dieholder has a central aperture 7<e> to allow the dies to be inserted and removed.
