156 MINING AND SCIENTIFIC PRESS. [September 6, 1870. The Mechanics’ Fair. The following ars some among the most interesting exhihits in ths fair: Manufacture of Metallic Laths. Mr. Chas. H. Carter has a machine for manufacturing metallic laths at work in ths machinery department of the pavilion, both the form of the lath and the machine heing of Mr. Carter’s invention, recently patented through the Minine anp Screntiric Press Patent Agency: Metallic laths have heretofore heen formed in sheets in a series of corrugated pieces, adapted for placing on broad, smooth places. The new metallic laths are made singly, and have a eurved central portion with extending flanges, hy means of which they may bs attached to the wall. They are made iu long strips, each one separate, and may be put in place like ordinary wooden laths, and weigh about as much. When placed side hy side, the space formed hetween the raised portions of the lath produces a depression which forms the hend to hold the mortar in place. The machine for forming the laths is a simple though ingenious piece of mechanism. A sheet of metal of snitable dimensions is pushed under the plates from oue side. The eccentrics, as the shaft is rotated, force the sliding plates down, thus forcing down ths oppositely placed levers. These levers foree down the upper edges of the swinging presser plates, the lower sharpened heveled edges of which squeeze the overlapping edges of the metal plates from which the laths are formed down over the rounded edges of the former, and into a crevice on each side. The eccentric again raises the swinging plates and separates their lower edges, releasing the lath, which may he drawn out, and a new piece of metal inserted. The laths, thus formed singly, csn be put upon any surface, and formed or bent to fit corners or angles; while they at the ssme time provide a perfectly fire-proof wall and a hond to hold the mortar in place. The Carter lath is now heing put iu the new Hall of Records in Oakland, and will no douht come rapidly into use in all buildings designed to be fire-proof. Bruckner’s Ore Mill There is on exhibition, in the display of Prescott, Scott & Co., in the fair, oue of Mr. Bruckner’s ore pulverizing cylinders, a machine of which some 80 are in use in Europe, and which is now meeting with the favor here, which experience ahroad has induced. The machine was invented some two years ago hy the wellknown metallurgist, Mr. Bruckner, to replace, if possihle, the costly and cumhersome plant necessary for crushing hy the ordinary stamp battery so much in vogue on the Pacific coast ; and from the facts, which are from the experience of a considerable period, our readers can judge for themselves of its value. It is constructed somewhat on the principle of the ordinary holt-polisher, with which every machinist is familiar. It consists in the main ofa eylinder four feet long and four feet in diameter, iu which a numher of iron halls are placed, and which, when the machine is charged with ore, is rotated, to produce the necessary grinding, The cylinder is constructed of flat steel rails of ahout three and a half inches in width, placed hoop-like at distances of 3-32 of an inch apart, and securely fastened together hy iron braces. The ends of the cylinder are made of strong sheet iron, The ore is charged hy any continuous feeder through one of the trunnions on which the harrel turns. Around the cylinder and fastened to it is placed a cone of cast iron, so that the pulverized ore falling through the apertures hetween the rails is eaught hy the cone and carried hy gravity to the part having the greatest diameter. Here is placed a hollow, annular riug, which forms a natural depository for the ore. This ring contains two eylindrical sieves. The one is made of strong punched iron or steel, and is made with 18 holes. This simply serves to protect the other, a wire screen, which is placed heneath it, This sereen is usually a No. 30. The next object is to remove this pulverized ore, which after having passed the No. 30 screen lies at the lowest part of the outermost compartment of the annular ring spoken of above, This is effected hy a curved tuhe or channel of east iron, which rnns from the bottom of the outer compartment along the end of the cylinder to the hollow trunniou opposite that at which the ore entered the cylinder. With such an arraugement it is evident that the revolution of the cylinder will naturally discharge the ulverized ore through the hollow traunion. y a similar arrangement all the ore which has passed the No. 18 sieve, hut not the No. 30, as well as that which was too coarse for the No. 18, is taken hy a similar tube and discharged hack into the cylinder itself for repulverization. A little reflection will make the working plain, and it is evident that the whole operation is automatic, and that with a proper ore feeder no attention whatever is required to the apparatus, In a eylinder of the dimensions given it is usual to work with about 1,500 pounds of iroh halls. The cylinder is rnn at a speed of from 15 to 22 revolutions per minute. A 5 to 7 horse-power engine only is needed. Perhaps the testimony of Mr, Arnold Lohse, a practical mill man, and chief engineer at La Barranca, Sonora, whsre two of thess pulverizing mills have heen used for two years, will show practical results hetter than anything. He says: ‘The one at the mill, which is 48x48, discharge screen No. 35, running 27 revolutions per minute, grinds 20 tons of silver ore in 24 hours. “Power necessary to propel it is 7 horse-power. The one at the mine is 48 diameter by 36 length of harrel, run at 22 revolutions per minute. Discharge screen for sizing ore for concentrators are 16, 12 and 8, and grinds 30 tons in 24 hours, easy. The repairs are not more than on batteries, and to say the least, your pulverizer is bound hefore long to dismiss the use of batteries in mills.” The cylinder is usually run in connection with a Blake Stone-Breaker, and ean be fed with anything from two to four. ¢ inches in diameter. It will orush either wet or dry, and in the former case the water may be used over and over agsin, a great advantage in dry districts. Besides the advantages presented, there are some which have heen hinted at only, and are evidentfromthearrangementof the machine. There isno useless work done. As soon as the ors is crushed fine enough to pass through the slits hetween the rails it passesout, and there is not that useless waste of energy so constant in the stamp hattery. Also, ths ore is not ground to that impalpable fineness which gives such a loss in the slimes of all our ordinary amalgamating contrivances. Next, the wear and tear of the parts is small. Machines of this kind, with a capscity of two tons in 24 hours, can he purchased for $250. One with a capacity of 20 tons costs $2,000. Mr. W. Bruckner, No, 328 Montgomery street, room 16, csn furnish any further particulars if desired, Waste Pipe Cut-Off In the machinery department of the fair, near the hig engine, is exhibited a waste pipe cut-off and valve for water closets, recently patented through the Minne anp ScizntiFic Press Patent Agency hy Levake & Gruhh. This closet has 8 metalseat, and dispenses with an overflow, providing for valve overflow, making it a sure preventive of sewer gas entering dwellings in which the closet is placed. It also dispenses in new work with traps of all kinds, which are usually worse than useless, giving a feeling of safety which does not exist. In these closets a direct connection is always maintained hetween the outlet valve and waste pipe, aud any leakage occurring, passes into the waste pipe and not into the howl. When the closet ig not in use the lower discharge is always connected with the waste pioe, and no overflow is necessary in the lower bowl, since, as the valve is closed, there is no connection with the upper pipe, it heing tightly closed. In case the waste pipe should become stopped, all that is necessary 40 do is to raise the fall enough to open the inlet valve and allow the full pressure of the water to flow through the lower discharge pipe into the waste pipe, where the pressure will force the pipe clear. By this action the bowl continues closed, and no sewer gss or odor can arise, while the water may he allowed to flow as long as necessary through the waste pit. The waste pipe cut-off and valve may he attached to hasins, hoppers, or wherever a waste pipe isrun, The mechanical construc. tion of the device, though simple, is rery effective in accomplishing the purpose. Home Made Hardware. Morris & Son, of No. 1045 Market street, make an exhibit of a few articles, all of which are of their own invention and practically introduced. Of these the pneuniatic hell is prominent. The elasticity and mobility of atmospheric air fits it for hecoming, under suitahe appliances, the most perfect medium known for sending signals and ringing a hell. Morris’ hell is rung hy means of pressing air by a common hell pull through a small metal pipe or tube leading to the hell. It does away with all wires. For steamboats it is particularly useful, since in the case of wires hreaking frequent accidents occur. They show a steamboat bell with a detector attached. This consists of a small hell in the pilot house, which rings when the engineer's bell does, hut when the latter fails to ring the detector does not, so the captain or pilot will know it immediately, The pneumatic hell is in use in the Board rooms of the S. F, stock board, having displaced an electric hell, The Morris door kuob, recently patented through the Mryine anv SciENTIFIC Press Patent Agency, as was the bell also, is exhihited. This door knoh is adjustahle without any screws or washers, and fits any thickness of door readily, hy a very ingenious and simple construction. It has been adopted in the new city hall, and is rapidly coming into use. The firm also show an improved lock invented hy them and of home manufacture. It is a five-tumbler lock, very light and strong. It is adapted for prison locks, as well as for general use where care is to he exercised. Morris & Son also manufacture locks and hinges, hronze work, nickelplated goods, as well as hells, knohs, ete. Wm. Hawkins, of 210 Beale St., exhibits in running order his improved elevator hoist, pattented through the MINING ANDSCIENTIFIC PRESS Patent Agency not long since, The only gold medal awarded at the fair last year was given for this machine. A long revolving screw carries the cross-head to which the hoisting ropes are attached, thus hoisting the elevator steadily and easily, without any jerk or jar. Six-horse power propels it. c eS Pa TENTS AND a) NVENTIONS. List of U. S. Patents Issued to Pacific

Among the patents recently ohtained throngh Dewey & Co.’s Scientiric Press Americsn and Foreign Patent Agency, the following are worthy of special mention : ImpRoveD CULTIVATOR, HARROW AND SEEDsowER.—James Hugill, Woodhridge, San Joaquin county, Cal. Patent No. 218,975. Dated Aug. 26th, 1879. This invention relates to an improved farming implement, hy which the ground is harrowed, cultivated and seeded at one operation, therehy saving a grest deal of time and expense for farmers. The construction of this machine is simple and not liahle to be easily hroken; it consists of two large rollers arranged to operate independently of each other, rotating freely upon an axle which is journalled in a frame; on the ontside of these rollers are placed in diagonal lines a series of teeth, Behind these two larger rollers is a sinall one having teeth arranged so as to keep the teeth on the large rollers free from lumps, and is connected to the larger rollers hy means of a set of gears. Near the rear end of the frame is arranged a seed-trough in which the seed is placed and dropped as required, and af. terwards covered hy means of teeth secured in the rear beam of the frame. Automatic MINE-DRAIniIne APPARATUS.— Joseph R. Wilcox, S. F. Patent No. 219,050. Dated, Aug. 26th, 1879. This invention relates to an improved apparatus for raising water from mines, wells, ete., and consists in providing two sets of three cylinders each, one set inside the mine and the other set outside, the latter being placed at a lower point than the inside set, Hach set of cylinders is placed in line, so that one piston-rod may carry three pistons, one ior each cylinder. Two pipes connect with opposite ends of each of the central cylinders, so that a continuous pipe leads from one end of the inside central cylinder up and down into the mine, connecting with the outer end of said inside cylinder, thus forming a continnous double water colamn when said pipes are filled and sealed. HorsE Power ror Orgrarinc Pumps, — Henry M. Cox, Linden, San Joaquin county, Cal. No. 218,938. Dated Aug. 26th, 1879. This device consists in the employment of a bevel or crown wheel, which is fixed upon a hed with its teeth uppermost. A central spindle arises from this wheel, and an arm or lever mounted upon this spindle extends across ahove the gear wheel, having an attachment for the horse at one end, while a pinion at the other is mounted to rotate upon its axis hy meshing with the teeth of the large wheel while the lever is carried around hy the movement of the horse, A crank-arm upon the pinion is nnited hy a pitman and universal joint with a halance-beam ahove, and the action of the crank causes it to oscillate so as to operate a pump at the opposite end.” This device is simple and easily constructed. CompinED Boot anp Lecoinc.—P. McNulty, S. F. No, 218,995. Dated Aug. 26th, 1879, The object of this invention is to provide a comhined hoot and legging adapted to fit over the pantaloons and fit the ankle and leg symmetrically; and it consists in a hoot having one side of the leg narrow and the other side projected toward the front to a sufficient width to wrap over the front of the leg onto the other side of the boot leg, the sides heing provided with fastening devices, and connected at the front with gore of thinner material, and lapping over when the leg-flap is secured, Raitway Track Lusricators. — T. P. Smyth, Cuffey’s Cove, Mendocino Co., Cal. No. 219,028. Dated Aug. 26th, 1879. This device relates to a novel method for preventing the retarding friction which usually occurs hetween the moving trains upon railways and the rails where curves exist; and it consists in the application of water to the rails and wheels in such a manner as to prevent in a great measure this rstarding friction, while at the ssme tims allowing sufficient direct adhesion for the purpose of traction.
