SD, i A BY DEWEY «& Co., Patent Selleltors. «€ J a . NDUSTRIAL PROGRESS, inent TONS, SATURDAY, MARCH 23, 1872, VOLUME XXIV. Number 12, Pelton’s Improved Horse-Power. Onr illustration represents an improved horse-power which combines strength, compactness, a large wearing surface and consequent dnrahility. It consists of two sets of triple gears, one arranged ahove the other, both of them driven hy the same master-wheel. A case or hoxing of novel construction and application covers the gearing or moving parts, which protects the power from dust and foreign bodics and men from danger of accident. A represents the bed-frame upon which the horsepower is secured. Tho annular metal hase plate is properly secured upon the frame A, and has a raised outer rim or vertical flange, C, which is formed into alternate raises and depressions, making the lower half or section of a circular hox. The douhle set of triple gears are arranged inside of this section of the box, the two sets heing arranged in alternation, and each of the six-toothed whecls engaging with the centre pinion which is made witb a suflicent face to admit the engagement of hoth sets of triple gears. The horizontal bevel wheel is driven by the centre pinion heing socnrod to the lower end of the same shaft, aud it in turn . ’ drives the tumbling-rod. Nis the upper half of the cirenlar caso, inside of which the train of gears is placed, and it is arranged with a downward projecting flange, O, which is also provided with alternate raises and depressions corresponding to thoso on the lower half, so that when the two flanges are placed together the projections will interlock and forma snuglyfitting side to the case, so as to resist the torsion conseqnent on the application of the power. The upper section of the hox, Ny, is also annnlar, and recesses are made in the proper position around its innor edge, through which the pinions pass, so as to stand above the npper face of the npper section, NV. A raised ring is securcd around the inner edge and ahove the circular opening in the upper section, NV, being secured to it by flanges which project downward so as to leave sufficient space above the ,recess to allow the master-pinions to project above the case or box. The journals on the npper end of the vertical shafts which carry the double set of triple gears, hear and are supported in the holes in this ring, while the journal of the shaft wbich carries the center pinion hears in the cross bar below. Tho master-wheel, U, is an annular one witb internal gears. In order to protect the gearing inside of tho box, a cap or cover, V, is secured upon the raised ring, thus entirely concealing tbe operating parts, and preventing the master-wbeel from being lifted or displaced hy any means. The four levers, z, to which tbe borses are attached, are secured to tbe masterwheel by means of a hook or curved bar, Y, which is secured to the end of each lever so that extend beyond tbe in a end and z, are mado through the upper face of the master-wheel, parallel with its rim, and the hooks, ¥, inserted hy clevating the outer ond of the lever until the end of the book enters tho slot, z. The lever when depressed will then he supported upon the mastor-wheel hy the hinding of the hooks upon the under side of the wheel. The braces, e, are provided at ono end with a similar hook which is inserted into tbe slots, 2’, in the vertical rim of the annnlar masterwheel in tbe same manner as that of the levers. The outer extremity of the hraces, e, are secured to the levers near their outer ends hy a loose joint. By this manner of arranging and applying the triplo gears, a large amount of wearing surfaco is secured, and the strain is distrihnted more evenly, thus insuring durability and strength, while the entire machine is at the same time in a compact and convenient form. The arrangement of the box or incloscogs bright and smeoth, owing to the great extent of hearing surface. This invention was patented throngh the Sorentrric Press Agency hy Samuel Pelten, of Marysville, Cal., who may be addressed at that place for further information. 2: am oo The Mining Incorporation Bill. TYhe ‘‘ Mining Corporation Bill,” one of the most important that has come hefore the Legislature this session, passed the Senate after a determined opposition, on the 19tb inst. It provides that one-half of the stockholders of a company may call a general meeting at any time, and that two-thirds of all the stock may remove trustees and appoint new ones in their stead. One-third of the stockholders may call for a statement of the affairs of the company. The provisions of the hiil will do much to secure persons of small means in holding mining stocks, but would bave
ing case is at once economical and convenient. While it not only protects the gearing itself from injury, it completely obviates any liability of accident to lifo or limb, which the ordinary open borse-power is apt to occasion. It also excludes dust and dirt from tho mazhinery, so tbat it will not be necessary to be continually cleaning the journals from tbe accumulatiou of gummy or otber matter, thus saving oil and time, while the macbine willrun much easier on acconnt of its keeping clean. Tho device for attaching tbe levers and braces is especially useful, as it will allow of all neccessary changes in tbe elevation ofthe outer extremities of the levers, witbout in any way affecting the attachment; while it at the same time provides a strong, simple and convenient means of attaching these pieces to the horse-power. Ovwing to the extended surface of the journals tho power only needs oiling once a day. The construction of this power is such that, as willbe evidont to any one familiar witb this class of machines, from 25 to 50 per ceut. more power can be gained with the same steam than any other tbe hook sball. horse-power will furnish, and it will take use in driving a. mines whose interests they were supposed at least 30 days’ S,PELT ON PATS FEBR, 6.1872 a Vv g heen still hetter if a simple majority of the stockholders had the power to remove trustees when desirable. Heretofore the trustees of mining companies have been elected for one year, and having complete control, did pretty mucb as they pleased without regard to the wishes of the stockbolders. Tbere has long been a necessity of a law of this kind, and many a man who bas beon fleeced of hard earnings by the manipulations of stock by trustees will beglad to know that people are now to have some protection. Mines bave been run in the interost of trustees and not for the benefit of the parties who pay the assessments and furnish the money. The stocks are ‘pulled and beared” by parties on the ‘¢ inside” without any apparent relation to the actual value of the mines themselves. A mine may run up, according to the value of its stock from $100,000 to $3,000,000 during a year, and yet he actually worth no more at the end than at the beginning. Another great evil has heen that the trustees have frequently used the funds of the company at different times for the purpose of manipulating the stock of the very line with the lever. Holes or slots, . tbreshing macbineto get tbe master piston . to uphold. As the means of carrying on the business of mining is most conveniently done hy means of incorporated companies, that great interest should be as properly protected as pessiblo, and in no way can it be done better than hy restraining the acts of unreliable trustees, and allowing the real owners of mines a voice in the affairs of the company they support. The bill as passed will prove of great value to all who are interested in mining operations and cause a reform in many practices which have heretofore been indulged in to the detriment of parties huying mining stock as a legitimate investment. oe oe State Geological Survey. The hill providing for the continuance of the State Geological Survey and appropriating $2,000 per month to defray expenses, bas been signed by the Governor, and that necessary and highly useful work will now go on towards completion. The leading papers of the State bave advocated the cause of the Survey strenuonsly, and although considerable opposition bas heen manifested by a few non-progressive members of the community and those who have no desire to promote the cause of science, we are pleased to see that the memhers of the Legislature and the Governor have been fully awake to the interests of the State in taking the neccessary steps to ensure its successful opcration. We have already given a description of the work that has been accomplished by Prof. Whitney and his able corps of assistants, and that which it proposes to do, If the maps and hooks that have been, and will be, issued by the Survey were in such places as to be convenient to the miners throughout the State, for reference, that partieular class of men, who represent a large and growing interest, would be materially benefitted, But not only to them, but to the farmers, and in fact all classes of our community will the advantage of the work accomplished, accrue. The #ulletin pnts forth a very good suggestion that the Geologist ought to be authorized to forward copies of the books to learned societies in America and Europe, and ,to the leading libraries in this State and elsewhere. This would not only bring credit upon the people of this Coast as an enlightened and progressive community, but the exchanges we would he likely to receive would be of great use to us. We hope shortly to hear of the completion of the maps which are in hand at the office of the Survey, and congratulate not only Professor Whitney, but the people of the State of California, that this most necessary measure is now sure of completion. Toe Commerce oF THE Wortp.—The aggregate international commerce of the world, at the present time, is estimated at $9,237,000,000 in value. Of this large amonnt Great Britain, mainly througb her subsidized steamship lines, is able to control within a fraction of $3,000,000,000— or nearly one-third of the entire world’s commerce. It behoves the United States to be actively in earnest, in reconstructing ber commercial marine.
