Vaartmat actiscias "es ‘lent e-tcel! ont erlisnt en’? « = Se An Illustrated Journal of Mining, Popular Science and General Neve. Br DOEWILY & CO., Patent Solicitors, SAN FRANCISCO, SATURDAY, JULY 28, 1877, VOLUME AXAV. € Number 4, Notices of Recent Patents. Among the patents recently obtained through Dewey & Co.’s Screntiric Press American and Forcign Patent Agency, the following are worthy of meution: Coat Evevator.--John A. Woodward, S. F. This invention relates to on improved machine for unloading cargoos of coal and other similar substances from the holds of ships and at the samo time screening the coal and delivering it into carts upon the wharf. The machine is constructed upon the elevator plan and is made in two parts, each of which is portable, so that the machine can be easily moved from place to place and adjusted to the location and pecubar surroundings of the vessel. One of theso parts is supported on the vessel which is to be unloaded, and consists of the frame work around which the endless chain travels, while the other part supported upon the wharf consists of the reservoir or hopper into which the screened coal is dumped by the elevator buckets and from which it is delivered into tbe carts, The operation of the machine is as follows: The upright frame is lowered down the hatchway of the vessel hy means of a shaft, pinions, and rack until a semi-circular box or trough rests upon tbe coal in the ship’s hold, where it is held by a ratchet and pawl. Power is then applied to the driving shaft and the endless belt with its buckets is set in notion. The coal is shoveled into the box or trough, from which it is taken by the buckets and carried up over tho frame and cast upon the screen. The screenings or fine coal pass through the perforations in the plate and are directed by an apron or shute over the side of the hox upon the wharf, while the morchantahle pieces of coal fall into a box or reservoir provided for them. AQuarRiuM.—Mathew Palen and Daniel Sexton, San Bernardino. This invention consists in constructing aquariums in such a manner that a portion of the water can be raised into a chamber which extends above the level of the water in the main tank and sustained there hy atmospherio pressure so that the fish in the aquarium can pass from the main tank into this elevated chamber and back again at will. This invention can be applied in a variety of ways, so as to produce mysterious and illusory effects, The Mechanics’ Institute Fair. Arrangements are heing perfected in all the departments of the Mechanics’ Institute Exhibition, Workmen are overhauling the building and goods are coming in rapidly. Unusual demands for space have been made. To relieve the pressure an addition of 100x100 feet will he made on the east side of the Market street end of the structure. Workmenare now engaged in takiny the seats out of the pavilion and otherwise preparing it for the reception of goods, The garden will be adorned with new features, principally in the matter of rockeries and a waterfall, An addition will he made to thelarge fountain in the center uf the main building, aud in the tank or hasin thus added will float workiug models of niouitors and other vessels of war. ‘hese will be from Mure 1sJand. The exhihits from the Mastern States will be much larger than usual, and will iuciude several that attracted attentiun at the Centennial. ira H. Chapman, for many years au engineer of the fire department, has been appointed Superintendent of the engine department. Superintendent Gihnore is at the pavilion locating the ditferent exhihits. The large paiuting for the south end of the gardeu has boeu completed and is spoken of as very handsome, Altogether the prospect is good for a mnch hetter exhibition than ever before, An advance edition of the Mecuanics’ Farr Day, to he published by Dewey & Co. during the fair, will he issued next week, Tue latest war news is to the effect that Ingland is becoming very restive on account of Sussian success, and intervention is threatened, Diagonal Planing and Polishing Machine. In establishments whoro cottage and chamher furniture is madothere are several kinds of planing required. First, common surfacing or thicknessing of lumber for inside work, Second, smooth planing of panels, and otber outsido surfaces. Third, smoothing of door and similar frame work parts, after they are made up, In ea penier and joiners’ shops the same work have to be done; 50, also, in classes 0: planing, tootb planing, scraping and sand-papering, in the cases referred to, and produces the hest quality of surface for about the saine amount as common machino surfacing costs. Several months of successful use in the hest walnut furniture factories in New York City, has decided that it is perfect for tho uscs for which it is intended. . A glance at the euts will show that in its entirety, it is a diagonal planing and polishing machine, the component parts of which are, a Woodworth planer of ordinary type, with the cylinder so constructed that its position may be NORRIS DIAGONAL PLANER FOR HBAVY SURFACING. the mauufacture of cabinet organs; in building railroad and strect passenger cars; the inside finish of vessels; some agricultural iunplements; wagons and a large list of other articles. The common planing is usually done with ordinary planing machines; the smooth planing with panel planers and hand planes; _ the changed at will, from its usnal one of square across, to diagonally, or vive revsa ; and a revolving disk sand-paper polishiug machine, all constructed so as to he worked scparately or conjointly, as necessity requires. It has various

The two latter methods involve hard labor, skill, time, and consequently great expcnse, proportioned to the nicety of the snrface obtained, hut in all cases great, even when the work is poorly done. We illustrate herewith a new machino which, while itis one of the hest staudard surfacers, also does away with the necessity for hand For surfacing of rongh lumher the cylinder is used square across, the polisher discounected, and the machine used exactly like ordinary planers.’ For smooth planing and planing of framed articles, the cylinder is used diagonally, with the appropriate rate of feed, For planing or polishing of lumber or frame work, the cylinder is used diagonally and simultaneously with the polisher; in this case, stuff enters with rough, uneven surfaces, to emerge planed and polished ready for oil, filling, varnish or paint. For planing and polishing wide waluut and other hard wood boards, a reciprocating polisher, or eylinder polisher, is u+ed after it passes the disk. (It is not sbown in these cuts). In ordinary doors and frame work the disk works with the grain. The cost of common surfacing is the saine as with ordinary planers, that of smooth planing panels and frame work and planing and polishing, from tifty te oue bundred per cent. greater. The machine is the inveution of Mr. Wm. R. Norris, of Fort Ann, N. Y., well known for several years past as the introducer and mauufacturer of the diagonal planerand diagonal planing and polishing machines, to be found in ucarly all the important door, sasb and blind factorics of tbe East. What the latter machines do for door, sash and blind mannfacturers the new machine is surpassing in the case of furniture factories and the other trades mentioned. Further informatiou can be obtained by addressing the inventor and manufacturer, as above. Items of Interest from the Mines. Wo give below items of interest from prominent mines, most of which are collated from letters of the respective Superintendents on file at the offices in this city: In the Overman tbe drift which was being run north on the 1400-fs0t level was extended 21 feet, at which point a eonucetion was made with the Belcher south drift on the 1600.foot level. The current of air is very strony, hut hot; temperature, 105° The Crown Point compauy are cleaning ont some of the old drifts ou the 160 and 300-foot levels, but have not yet reached the point at which it is believed considerable ore may he found. ‘They have rented the company’s mill, the Rhode Island, to Mackay & Fair, at $1,500 per month, 7 ; The north drift of the Andes is still turning out some low grade ore, but not enongh to keep the mill running, so it was compelled to shut down for the preseut. ’ North drift 1600-foot level of the Mexican showsa decided improvemeut, being all in nice vein matter,j with stringers of quartz coming in. The Superintendent of the New Coso says: There has heen marked improvemeut in the quality and width of ledge in stopes. Since I wrote last I am taking ont ore superior to any jyet extracted, with every prospect of contin uance. The uorth drift from foot of winze is uow in good pay ore, and the quality is improving. Phey have had to put a blower in the Panther mine, as the air has heen quite bad. Men have been compelled to stop sinking main shaft at the Tybo Con. nine ana timber the same, the ground growing very hlocky and soft and dangevons, and they thougbt it hetter and cheaper to timber to the 7th level at onve than to partly timber it. The Ghollar-Potosi turned out last week 521 tons of ore, assaying $22 per ton. ’ ,An improvement bas taken place in the face of south lateral drift 1000-foot level of the Justice; the width of the vein which produces the ore is three fect; the whole vein has a more lively aspect. The upraise and stopes from each end continue to devclop a body of fair m lling ore, a. ‘he Ophir is hoisting and shipping the usual amount of ore to the Winficld mill. The Eureka Consolidated letter is as follows : The miue shows decided improvement at all points at which work is heing done; the fifth and sixth levels showing great improvement during the past weck. The third level is still in hard limestone, but with good indications for ore in face of drift. Connections have been made from 70 feet above the fifth level to 100 feet helow the ninth level, a distance of 580 feet, all the way in ore of about the same grade as that smelted during the last six weeks. The furnaces have been running well, having produced 328,379 pounds of bullion from 759 tons of ore during the past week. Everythiug working well at mines and furnaces.
