For grinding or crushing calcium-carbide, the employment of a grinding- or crushing-mill in which the operation of grinding or crushing takes place in the presence of hydrogen or hydrocarbon gas, substantially as described, and for the purpose specified. (18.) Generating-apparatus for acetylene gas which consists of a generating chamber a with right- and left-handed traversing screws or conveyers d, e, feeding-hoppers f, g, regulating taps or valves j, k, and outlet o for exhausted residual products, combined and operating substantially as described with reference to Fig. 1 of the drawings. (19.) Generating-apparatus for acetylene gas which consists of a drum t divided into compartments z 1, communicating with one another by openings 4 and 7, said drum being adapted to be rotated within an air-tight casing u, the drum t and casing u being provided with charging- and discharging-orifices, combined and operating substantially as described with reference to Fig. 2 of the drawings. (20.) In apparatus for storing acetylene gas, the employment of a gas-reservoir which consists of a submerged gas bellows or bag 9, arranged and operating substantially as described with reference to Fig. 3 of the drawings. (21.) In apparatus for generating and storing acetylene gas, the means for automatically mixing the carbide with the decomposing material as the reservoir 9 becomes exhausted which consists of the rising and falling rack 15 and pinion 14 acting upon the moving part of the generating-apparatus 13, arranged and operating substantially as described with reference to Fig. 3 of the drawings. (22.) In apparatus for storing acetylene gas, the employment of a liquid seal consisting of a solution of water-glass, substantially as described.

No. 12805.—21st July, 1900.—JAMES JOSIAH SMYTH, of Peasenhall, Suffolk, England, Agricultural implement Maker. Improvements in machines for distributing manure broadcast or in drills.

Claims.—(1.) In manure-distributing machines such as described, the coupling-together the scrapers, which act against the revolving measuring-discs, in pairs, by short levers at the back, in such way that when one scraper is moved backwards the other must move forwards, whilst at the same time the discs against which they act are so set that when one scraper rests against a prominence on one disc, the other scraper rests in a cup or recess in the other disc. (2.) Mounting the bar upon which the several scrapers are hung upon pivots at its upper end. (3.) The construction of manure-distributing machines substantially as described, and illustrated in the drawing.
