149 MINING AND SCIENTIFIC PRESS. {August 29, 1874 The Motive Power at the Pavilion. The engines now driving the machinery of the Fair are from the Union Iron Works, Messrs. H. J. Booth & Co., and evince a very important advance step in the production of a stenm engine combining simplicity of construction, economic resnits, beanty of design, few namber of pieces, and access abiliry of all parts These engines appeal to the judgment of every one as being the machines needed for this coast. The cylinders are 12 ‘bore 24” stroke, having the steam chest and foundation cast in one piece; the steam ports are very short, being naarly at right angles to the face of valve. The valve has a large lap and quick stroke, The bed embodies the well tested and correct principle of oentral bracing, frst introduced by Corliss, and in this case most admirably carried out. The pillow block has the most improved method of7 adjusting the qnarter-hrasses, which insures a compleis support on the entire surface of the brass, while being adjustable in every direction. The foundation is cast to the pillow block, making a most complete and simp!e equivalent for the old, expensive and cumbersome bed. The crank, top of pillow block, steam chest, throttle valve, Zs-wheel and governor, are all splendidly finished, and in harmeny with the general design. -The valve stem and eccentric rod connection are carried in a simple and mechanically designed guide, accessible and sub. stantial. The cross-head has large gib snrfaces, adjasted hy set screws and within reach and in sight stall times. The cross-head pin is of steel, with an automatic oiler-attached. The lower slide 1s suppliad with oi) from a s'ationary oiler under fall control of the engineer, while the engina is in motion. In fact, every part of the engime ssems to have been designed with especial reference to the convenience of Inbrication, adjustment and rep ir. The oilers used are the Dreyfus Glass oilers on the wearing, and the Seibert Eureka oiler on the ecylmier. One engine is fitted with Watson's steam packing for the piston rod, and one with the old-style hemp packing. The governors are of the Lamott patent and Hendys mannfacture, embracing the automatic stop ju case of breakage of belt or gear, and have separate adjustment for nice regulation of spred; they are well boilt and nickel plated. The cylindsrs are cased with black walnut held in place with sliver plated screws. All the nats are sapplied with fmished washers, something not arnaly done, thongh it adds mach to the general appearance. The engines are intended to be used for the Palace Hotrl, now tuilding, and we congramlute the owaers on the wisdom of their selec tion. If the balanes of the appurtenances of that hotel are made in keeping with the engine, the pablic can have no fanit vo dnd. Miners and Mechanics. Do mining men often think how mach they are indebted to the artisans and mechanics ¢ Without their assis‘anoz mines conld never be wolked to the depth they now are, and cre production wonld be necessarily lHmited for waut of proper hoisting machin-ry and crushing apparatas. At the same time the artisans ure very slightly affected by the sneorss or failure of individnal mimes, Wild speculation, haste io be rich, incompetent and exiravapant superintendence, fictitious compsnies, éte., have depressed the mining interests of our State irom nme to ime; yet the inventive, practical mechanic and miner have been at work sontinnally, experimenting and perfect ing improved applications of motive power, NEW processes, new pumps, and all the differeut appliances veadinl abouts mime. The foundrymen of this city have grastly aided the mining interests of the oonst in their stoc: ssful efforts to manufacture improved mining machinery, thongh the mimers scaroely give them tbe proper credit for the mann-r in which they have simpliged and strengthened mining appEances. Tux chinch bors are making serions inroads on the corn crop of Brown, Pits, and sdjoining counties in Tiinois, and there is no calculating the extexi of damage that will be sustained to this cerexl; es the insucta are seemingly jost beginning to muke their appearance. “It may be safely estimated, say a good many farmers, that ut Jeust one-half of the corn erop will be destroyed. Cris. D. Greens, of this city, has been appointed United Stutes Depnty Minera] Surveyor, by James T. Stratton, U. 8. SurveyorGeneral for California. Mr. Gibbes is an old Onlifornian, perfectly familiar with every part of the State, and wall Epown asa most eficient and rehable surveyor. The eppoiztment js an excellent one, Necormvioxe are on foot for the srle of the Perrin mine, severa) miles below Grass Valley. on Wolf erack, and the O°Connor mine, be longing to an English company, situated near . 3 Txion hill, Nevada oounty. Tsunr is alarce deposit of cobalt near the hesd of the Walker river, and it is being extenstvely worked. The ledge bas been traced fer 6 jong distance, and ore is being taken ont im Give or six places. Our Press in the Pavilion. We venture the assertion that there are few ; more interesting pieces of machinery than the modern cylind-r press. Look at ours at work. How rapidly and neatiy it tums ont our immense paper, and yet how quietly it performs its dnty. We wonld say here that it is the pecoliarity of the Potter Press to work withont noise, jar or friction. reil’’ jobber is an excellent mate for it in this respect, Both machines are built for strength and move smoothly and easily along in their duties, withont the characteristic clatter and hang of other presses. Where there are crashing and slamming there are friction and wesr, just as surely us smoke is an indication of fire, . Reader, whether you are a printer or not, ¢xamine these representatives of modern excel. . lence in printing presses. Once thousand Potter . Cylinders are in nse in toe best offices of the Eastern Siates, without a known «enemy. Some of the finest illnstrated works of the land are printed on the Potter presses, and for the ex-. oclent and at the same time rapid execation of the general requirements of the joh printer, . the two-roller extra heavy machine is the . favorite far and wide. . An experienced and conscijentions printer . says: “‘ It is my conviction, alter a careful investigation, and comparison with other cylinders that the Potter is the best, as I find all the best points of the prominent machines retained, its renowped bunter spring and lever ale-ne places it far ahead of all others, in giving the bed that beautifol, easy movement at a high rate of sperd with vo tendency to jar, nor to work the ‘gnads’ up in the form. The rollers can he pot in or ont in half a minnte, and the distri. bution is very supsrior. The whole machine ; is solid, firm and strong, and the workmanship . and finish noexoelled.”’ ! The large factory, at Norwich, Conn., ie now . employing sboat 90 hands and torning out ten { machines amonth. To hring these cylinders . up to their present standard of exceflenoe avd perfection has taken many years, and a vast . outlsy cf money. We are glad that these presses are to be introduced on this coast; sand Enowing that the agent, Mr. N. C. Hawks, Manager of the Pacific Type Founiry, is a practical printer of seventeen years experience, we bave faith that he will succeed in proving their merits to all who are interested, and who . will call st 532 Clay street. It certainly gives . us an honest pleasure in adding onr evdorsement of the good quelities of the Potter press, and we will say in this connection of the new . type foundry also, which we notice israpid'y approaching considerahle magnitude and enjoyipg a good trade already. a Tze new heisting works of the Sisrra Nevada mine snooe-ded in two diya, witb a single tack, in clearing the shaft of 225 feet of waler. @at rf P ENTS & 4 NVENTIONS.
