Title: Improvements in the Manufacture of Artificial Stone
Filed: 1900-03-30
Granted: 1901-03-16
Abstract: 5995. Lake, H. H., [Wachtel & Co., D.]. March 30. Stone, artificial.-Relates to the manufacture of artificial stone from arenaceous quartz or materials rich in silica, such as flint, slack from smelting-furnaces, ores rich in silica, &c., and slaked lime. Instead of admitting high-pressure steam directly to the chamber in which the moulded blocks are treated, the chamber is steam-jacketed, and trays of water, the evaporation of which is facilitated by steam-heated coils, are contained within it, the result being that a gradual increase of pressure and temperature takes place, and cracks and strains in the stone are avoided. After the slabs or blocks have been allowed to cool, a solution of sesquicarbonate of ammonium is introduced into the vessel for the purpose of hardening the stone.

Title: Improved Means for Lighting and Extinguishing Gas Lamps and Burners at Predetermined Times.
Inventor: VOLLMANN CARL
Filed: 1900-12-15
Granted: 1901-05-11
Abstract: 12,367. Vollmann, C., Thielenhaus, F. W., and Thielenhaus, E. Dec. 15. Lighting and extinguishing gas.-The plugs of the bye-pass gas cocks of burners provided with pilot jets are actuated by clockwork mechanism at predetermined times to turn the gas on and off. By means of the gearing 4, 5, 6, the spring barrel 3 of the clockwork mechanism rotates each of the wheels 7, 8 once in twenty-four hours. Upon the respective spindles 9, 10 of the wheels 7, 8 are mounted the dials 11, 12, the pointers 13, 14, and discs 15, 16, which are provided with semicylindrical studs 17, 18. In the path of these studs normally depend the lower ends of two bell-crank levers 21, 22, which are respectively pivoted at 23, 24 to a lever 19, which is itself pivoted at 20 to the frame-plate 1. When setting the mechanism, the discs 15, 16 are turned backwards, the studs 17, 18 then pushing aside the pivoted levers 21, 22, which are immediately returned to their normal positions, in which the other ends of the levers are held in contact with the stops 20, 27 of the lever 19 by the spring 28. Of the two studs 30, 31 on the lever 19 which project through the frame-plate 1, the stud 31 supports a pawl 32, keyed on the spindle 34 of a second pawl 33 which engages with a pin 35 on The wheel 36. Through the gearing 38, 40, 41, 42, and 43, the arbor 37 of the wheel 36 is connected with a second spring barrel 44. The arbor 45 of the wheels 42, 43 carries a plate 46, which, by means of the pins 47, is coupled to the plug 2 of the bye-pass cock. The predetermined times for turning the gas cock on and off are respectively indicated by the separate dials 11, 12, which are adjusted relatively to the fixed pointers 48 by turning the discs 15, 16 backwards, as previously described. As the dial plates are revolved by the clockwork, the studs 17, 18 on the discs 15, 16 engage at different times with the ends of the levers 21, 22, which, being held rigid by the stops 20, 27, lift the pivoted lever 19, causing the pin 31 to lift the pawl 32. The pawl 33 on the same spindle 34 then releases the pin 35 on the wheel 36, which turns until a pm 39 on the arbor 37 is caught by the pin 30 on the lever 19, and held till the actuating stud 17 or 18 has passed its lever 21 or 22 and allowed the lever 19 to fall. The stud 30 then releases the pin 39, and permits the spring barrel 44 to drive the arbor 45 and the connected plug 2 of the gas cock through a quarter of a revolution, which is sufficient to turn the gas on or off. The pawl 33 is returned to its normal position to engage the pin 35 and stop the gearing by the engagement of an eccentric 49 on the arbor of the wheels 40, 41 with the pawl 32, which is on the same shaft 34 as the pawl 33.

Type-writers.-A cash register or recorder is shown in Fig. 1 which will visibly register the total sales of a day or any desired period and is provided with means by which the totals are printed on a roll of parchment at intervals when it is desired to set the visible register back to zero. The units keys D, tens keys 17, 18, 19 and 20, and the hundreds keys 21 are fulcrumed on a rod C and carry vertical rods J having recesses 4, varying in height according to the keys, and adapted to engage rollers H, 24 and 32 carried by arms F, 22, 23, 30, and 31 resting on stops b, a, and d. These arms turn loosely on a rod E and one of the arms F carries a pawl N engaging a ratchet-wheel K which communicates motion through friction or toothed wheels, as shown, to the units registering disc 8. The tens and hundreds registering discs 13 and 39 are similarly operated. A thousands registering disc 42 is provided. Each carrying- device consists of a cam carried by the disc and having a projection 12 which, by engaging the tail c of a lever pivoted at 47 and connected to the pawl lever 50, brings this pawl lever into the path of a projection 55 on the shaft 53 so as to cause the pawl lever to operate a ratchet-wheel carried by the next disc. The shaft 53 is operated on each return of a key by a pawl engaging a ratchet-wheel 64 geared as shown to the shaft. The pawl is carried by a lever connected by a link to a centrally pivoted lever frame held in contact with the key levers by a spring. The printing device consists of discs with raised numerals and carrying wheels kept in gear with wheels carried by the discs 8, 13, 39, and 42 by springs supporting the sliding bearings of the spindle supporting the printing-discs. The two central discs have retaining ratchet-wheels. An inking-tape, carried by two vertical spools one of which has an operating thumb-piece, is situated between the discs and a rubber pad over which the parchment moves from one roller, over a guide roller, to another roller. To take an impression the sliding bearings are operated by a lever carrying a pawl-lever held in contact with a ratchet-wheel, carried by the parchment receiving-roller, by a spring so as to operate this roller on the return of the impression lever. When the printing-discs are out of gear the numeral discs on the shaft 9 may be set to zero by a hand-wheel 11, the shaft having a groove with a shoulder to be engaged by spring dogs carried by the discs.

Title: An Improved Method for Conveying Vessels and the like from one Water Level to another in Waterways
Inventor: SCHNAPP FRIEDRICH
Filed: 1901-08-10
Granted: 1902-03-13
Abstract: 16,129. Schnapp, F. Aug. 10. Canals and rivers; docks. - Relates to transferring vessels from one level to another in waterways, and is shown in plan and sectional elevation in Figs. 2 and 4 respectively. The lower and higher levels w<1>, w<2> of the waterway are separated by lock gates b, c from a basin a, in which is a large float d provided with cut-away parts e, f to allow the passage of a vessel v. The float is divided horizontally into compartments n, o, p, q, r, s, which communicate through adjustable pipes t with corresponding outer reservoirs g, h, i, k, l, m respectively and through pipes w with the atmosphere. If the float is pressed down by external mechanical means, water flows from the reservoirs g-m into the compartments n-s and the float sinks, thereby raising the water level in the basin. An upward pressure on the float raises it and lowers the water level in the basin, the water in the compartments flowing back into the reservoirs. In a modification, the mechanical means are replaced by allowing some water to enter or to leave the basin a.

Steam &c. turbines.-A parallel-flow reversible turbine, which may be adapted as a single or multiple expansion engine, is shown in Fig. 2 as a compound turbine. The high-pressure casing A and the low-pressure casing B are mounted on the shaft C which carries the turbine wheels D, E. The turbine wheels are formed of metal discs 20 bolted together and having peripheral vanes which alternate with rows of fixed vanes secured to the casing. The fluid pressure normally passes from a row of nozzles 39 into the first wheel D and then passes through a chamber 71 and second set of nozzles 74 into the second wheel. The nozzles 39, Fig. 11, taper towards their outlets 53, and, instead of having wedgeshaped walls, may be formed with thin walls. The nozzle inlets are covered by a casting 55 formed with ports 57 controlled by a slide valve 58 which is worked by a screwed spindle connected to hand or governor actuated gearing, which also works a double sliding valve 77, 78, Fig. 9, by means of a screwed spindle 82, and so controls the supply to the second wheel E. The nozzles 74 of the wheel E are similar to those of the wheel D, but occupy a larger arc, Fig. 9. A set of reversing-nozzles, fed through a passage 40, are placed in the lower left-hand quadrant of the casing B, and these nozzles 36, Fig. 5, work in connection with rings of reversing-vanes 26 on the rim of the wheel E and corresponding rings of vanes 30 fixed to the casing. The vanes 25, Figs. 5 and 6, of the wheel E are cut in rings 24 which are bolted to the discs 20 to form the wheel rim. The reversing-vanes 26 are cut in metal rings 27 which are covered with bands 28 and bolted to the vanes 25 by bolts 29.

Title: An Improved Industrial Process for the Production of Hydrated Sulphide of Zinc from Zinc Ores.
Inventor: BERMONT VICTOR
Filed: 1902-03-19
Granted: 1903-01-08
Abstract: 6752. Bermont, V. March 19. Zinc carbonate, oxide, oxysulphide, and sulphide. -Zinc ores, such as those containing carbonate, silicate, oxide, sulphate, phosphate, arsenate, &c., are treated to obtain pure zinc sulphide. If a carbonate ore is used, it is crushed to the size of grains, and then treated with liquid ammonia. The resulting solution of zinc and other metals is separated, by decantation or filtration, from the residue, from which ammonia is recovered by heating. To the solution is gradually added a soluble sulphide, such as sodium sulphide, until all the metals, other than zinc, have been deposited as sulphides. When this occurs, the solution, which only contains zinc salts, is filtered from the precipitate, and may be treated as follows :-(1) to obtain zinc carbonate and recover the ammonia for re-use, the solution is evaporated ; (2), to obtain zinc oxide, the carbonate is roasted ; and, (3), to obtain sulphide, sodium sulphide is added. In the last-mentioned case, sodium-carbonate solution remains, from which sodium sulphide may be obtained for re-use by either a wet or dry method, and by using sulphur in any of its forms or combinations. The zinc sulphide may be roasted in the presence of air, to obtain the oxysulphide. When zinc salts insoluble in ammoniacal solutions are treated, they are first roasted or otherwise treated to transform them into the oxide. Instead of liquid ammonia, solutions of ammonium carbonate, sulphate, nitrate, acetate, or phosphate may be used.
