An Illustrated Journal of Mining, Popul i ar Science and & BY DEWEY & Co., Patent Solleitors, SAN FRANCISCO, SATURDAY, NOVEMBER 21, 1874. VOLUME XXIX Wumber 21. The Haskins Steam Engine. The accompanying illnstration represents a seml-portahle engine of 10 horse-power, made by the Haskins Machine Co., for whioh Parke & Lacy, No. — Leidesdorff etrect, San Francisco, are agents. Jt is claimed for this engine that aside from this perfect system of mannfactnre, it has many points of excellence. One of these points is claimed to be its genoral ontline. It will be neticed that all strains are met by straight lines, rather than cnrved ones which are regarded 43 elements of weskness, The valves used on these engines are the “ piston valves’? of Thomas §. Davis, long the snperintendent and msnager of the Jersey City Locomotive Works—which, though first constrncted and patented some ten years since, have stood the test of time thoronghly and successfully. On small engines, nnless epecially ordered otherwise, the valves are made to cut off at a point predetermined ; on others, an sutomatic ‘‘ent-off,” controlled hy the governer, is applied, insuring efficiency equal to the hest, For driving the valve the nsual eccentric is made nso of, with the exception of its mode of constrnction and adantation to this psrticnlar engine. It is msde fsst on the shaft, permanently, not with set screws or keys, bunt is made an integral portion of the shaft, ond then, onits periphery is ‘“‘shrunk”’ a reinforcing ring which is hsrdened and can he replaced in case of accident to its surface. No place is left for any adjustment of valve motion. Every part is made the exact length desired and pinned fast. No sorew or nut can be, changed to alter the desired results. Thns is the perfection sought permsnently secured; for, 50 soon 8s 8 change is allowed in the yalvé-motion of an engine, ynst So soon are the resnlts of the origins] engineering skill lost. The main shaft, the connecting rod, and all other hoxes are composition, lined with best Babhit metal, and sre made interchangeable. Their wear does not therefore affect the framing or lining of the engine. The connecting rod and its pins are very large at the bearing points. The cross head is provided with adjustahle composition gihs of very large surface snd self-centering. The piston rods and all the parts that reqnire it are of the hest steel. A neat and efficient plan of getting rid of drip water from the cylinder is peculiar to this engine, The device is contained heneath the jacket. When in use the drip water passes down inside the post and ont of the hase, and it can thus he carried off to the sewer, without in the least Soiling the floor. THE engineer of the Imperial mine was killed on Wednesday last. He was standing at the engine hoisting a cage np the shsft, when the cable broke and the upper section was hurled with great force sgainst him, striking his hreast and knocking him down. He lived only a few minntes, fi ‘ : illuminating Tiles. Mr, William Lynch of this city is determined to provide proper means fer lighting and ventilsting dark and unssvory places. A large experience in the mannfactnre of illnminating tiles has convincad him that to admit a few Z te te: straggling sunbeams into an wnderground apartment will not purify the atmosphere or render it a healthy abode, neither will it prevent articles stored in snch apartments from heing affected by the dampness and closeness of the atmosphere. A short time since. we deserihed in the columns of this paper, an improved ventilating blank to be used aiternately with the ordinary illuminating hlank in the mantfacture of illuminating tiles which waa patented hy Mr. Lynch. ‘We now report the issnance of another patent obtained hy Mr. Lynch through the Miyine ann Screntirie Press Patent Agency, for an improvement in connection with those ventilating blanks. His present invention consists in tap} ing the hole in the ventilating blank with screw threads and adapting thereto a short screw which can bo ecrowed np through the hold from underneath Academy of Sciences.

They had better depend on their mines for their proits, than on stock transactions. People will have more confidence in the mines if they stick to legitimate mining. presented by Captain J. W.
