= us = @ trated Journal of Mining, Popular Science and Progressive Industry. BY DEWILY & CoO., Patent Solcltors. SAN FRANCISCO, SATURDAY, FEBRUARY 14, 1874. t VOLUME XXVIII +» Number 7%, Morris’ Settler and Amalgamator. The acenmpanying illustration reprosents au improved aettler, recently patented throngh the Sciestirié Press Patent Agency, by Fredrick Morris of this city. It merits the ottention of the mining community not only for its unusoal cheapness, bnt for ita efficiency io working and novel metbod of discharge. . The machina has been in proctical operation for some littla time in this State and in Idaho. A fact that will attraét tbe sttention nf all mill men is that the settler gains quicksilver in working tailings, as has been repeatedly proved in practice. Ths vides-and bnttam are made of wood, as are olsn the mailers, leaving only the running gear of metal. This, in itself, is an important featnre, ax it is easily and cheaply transported, a8 well as easily and cheaply made and set np. The castings, gear, ete., weigh altogether only 520 Ibs.; tbe largest piece weighing 135 lhs. The wholo thing will weigh no more than the bottom alone of an ordinary settler. As will be seenin the detailed description of the settler, tbe bottom is made of wedge-shaped blocks, fastencd in a peculiar manner, 80 that there is not the slightest danger of tha bottom hniging or getting out of place. The action of wood agninst wood brightens the quicksilver without “flouring’’ it, as any miser knows. Tha bottom blocks, ussd by Mr. Morris in the settler Tonning at his place, were madc of common redwood, ond the revolving action of the mnllers slightly rnnghans it, giving the quicksilver a ohance to become brightened without ‘‘flouring.”’ Soft wood is preferable to bard for this reason. “ By referring to tbs cut the opera'ion of the settler can be seeu: A represents o tub or vessel, which’ can be made of wood or iron, in the oenter of which Tisea tha muller-supporting standard, b. The j bottom of this vessel is covered with a layer of wooden blocks, ¢,c, placed with tha grain standing vertically. Radiating wooden strips,-d,d, seperate the ssetions of blocks, ¢,c, at intervals extending from the center to the onter edge of the bottom. Thesa strips d,d, consist of boards placed edgewise between the triangnlar sections of blocks and so that their upper edges will be somewhat lower than thesnrfaca of the bloelks, ce. Aronnd the onter edge, of the bottom a ‘cbannel or deep grooveis mada between this wooden bottom and the sida of the vessel, for tha purpose hereinafter explained. The mullers, G, ara nlso constrneted of wooden hlocks secnred to the muller-arms with the grain of the wood standing vertically, so that all of the wear npon tha mniler and bottom will be upon the end of tha grain of wood, By.employing wood in this manner—for the bottom of the tnb and for the muller—much better results ean be obtained in the process of settling. The channel formed by tha depressed strips, d,d, serves to convey any particles of quicksilver, which may become separated, to the annular channel around the edge of thé bottom of the vessel. In order to draw off the water from the vessel a siphon, &, is employed which is secured upon tha edge of side of the vessel so tliat its inside leg will come almost to the center of the pan. By means of tbis siphon the operator isenabled to draw off the tailings or slime from the center of the vessel, where, by reason of 4 lcss amount nf agitation than at the sides, an eddy is formed, which is more favorable for allowing the heavier particles to settle than at any other point in the vessel; while at and near the eides the greater speed of tha muller keeps the-pnlp in constant motion, so that a portion of the amalgsm will always bs drawn off with the tailings when the discharga is at the side: This settler draws from nearer the surface than onr engraving would indicate. It can be made of metal or common rubber hose, as is most convenient. ,The settler is easily cleaned np in half an hour, ag the blocks can be rewioved without tronble. Making its sides of wood is a new and economical feature, as it Saves cost of iron and transportation. The eastings can ba sent to any mine, and the frama work, mullers, sides and bottom, can he mada by any carpenter. The blocks are set on edga like thoss in pavements, or in“ sluices, x At will and are ensily changed when worn down. ‘Lho wear and tear amounts to very little, ag wood is cheap in the interior, and a neighboring tree will furnish all the blocks neecssary. will not cost wore than $4 or $5 to make a new sct nf mullers, and new hlocks for tho bottom. . Very little power is necessary to ran the settler as thy arms and muilers are light and the setller draws off the sllme contiuuously. The wooden mullers and blocks can be nsed in iron hottoms, 80 that pans already Tnoning can ha altered easily. The idea of using wooden bottoms is not new, but Mr. Morris’ method of doing so is new. Although very simple it anawers the purpose excellently, and the wedge-shaped bottom bloeks do not bulge or crack. Ilis idea of drawing the slime is a good one, as any mill man will readily seo. Tt} Locomotive Bell Ringers. Engina nnmbor eight, belonging to the S.P.R.R., is one of Booth’s make, end was built expressly for yard work, it having to make np trains, do the switching, and all tha general work of moving cars in the yard and about the depot. Since its first advent on the road, it bas done some good work, and as a natural conscqneice it began to show visible signs of . wear and toar, that refused to allow themselves . to be overlooked; consequently she was hauled off the road, and pnt on the stocks in tbe ma. chine shop for general repairs. Her insida fire. box was found to be in a very defective state; MORRIS’ SETTLER AND AMALGAMATOR, Mr. Morris furnishes whole paus if desired, but prefers to sell only the castings and let the miners put up the woodwork thamselvee, as it is casier made on the gronnd. Parties owning mines or localities where freight is
high and roads bad, as in some of onr monntainons districts or in Mexiéo, will be glad to know ‘there is a settler which will not cost a fortuno to transport. Mr. Morris informs us: that he will ‘furnish these pans complete for $250. Ha will fnrnish castings and right to use for $175. He has been very successful iu eeparating magnetic iron amalgam with this pan, ‘in Joealitiés whera the magnetic iron created difficulty in pans. ’ One of these settlers is rnnning daily at Mr. Morria’ office, 616 Merchant street, where those interested can see it. Czoucn’s Excin#, which we described last week, has been placedon a dummy locomofiva on the Alameda horse ear line in San José. The loeomotive was put np at MvuKenzie’s foundry, hy Mr. Mitchell, It is said to possess great speed and power, though itis quite small. ill be run outside tha city limits, as the authorities will not allow it to run in the ‘ city. . Miners are leaving Pioche daily for the Stickeen country., They will rendezvous: at Victoria, B. C., until the. weather will_ permit of their going to tha mines. From all accounts. the Stickeen River country is apretty sevare ons to work in, ,.o . x le ls) aa ‘ this ‘vas taken out bodily, and a new one put in its place hy the foremon boilermaker, Mr. J. Kelshaw, who also pnt in a new set of flues. The link motion, slide valves, axle boxes, and all tha general machinery of a locomotive, were errefully examined,‘ and thoroughly repaired, so that when a few days ago'the engine took np her old position in the yard, it was with a feeling of safsty, satisfaction,. and pleasure that the engineer saw her settle down to the work, ‘just a8 good again as when she first left Mr. ‘Booth’s shop. ! Pek. But thsre was one new feature’ added during the sojeurn in tha machine shop, that could not but arrest the attention of any: passer by who might be near, while the engine wae in motion, This is what is popnlarly styled the bell ringer, or the “‘lazy fireman’s assistant,” As the engine is continually at work at varions points about tha city, and, in consequcnce repeatedly crossing and recrossing the streets, it was deemed essential to adopt soma method by which the bell shonld he continually sonnded as a warning to those near, and as tha employésin charge of the eugine could not be always pniling at the bell rope, an extra hammer has heen affixed to the frames of the bell, which, by means of rodsand levers, is alternately raised and allowed to fall again, striking the bell as it does so. Motion is com‘munioated by the cecentric, thus giving one blow on the bell for avery révolution of the driving wheal. Bnt.if the’ hammer were allowad to strike tha bell and remsin tbere until a Califortiia invention. lifted for the next stroke, of course it would kill the soned, To connteract this difficulty, a cleverly arranged spring, thoronghly tempered, is placed in such a position, that tho force of the downward blow allows it to givé enongh for the hammer to strike tbe bell, yet on the very instant of striking it lifts the hammer from the bell, tbus enabling the opparatns to strike a good ringing blow, so essential on the locomotive. Although looked at from a machanical point of view there are fanlts and blunders in its construction, yet the idea is good, and we shonld thank the 8 P.R.R., for having adopted it, and the genius of its inventor for having used his brain to such good purpose, . Its chief fanlts are tbat the hammer is too small, and the fall too little. Altogether it gives the idea of being ina cramped position, and too close to the bell. If the fnlerum had been thrown further out, and a longer lever and heavier hammer attached, tha resnits would have been more satisfactory; 25 it is, the sonnd prodnced is not lond enoygh. But as this is a maiden attempt of this style of bell ringer, at least in this city, it would be ungenerons-to be too criticol. but wa will aceept it in the spirit with which it is offered, as expressing a desire on the part of ths railroad authorities fo do all in their power, to avert tha danger of any casuality oceurring on thairnll too exposed road in and ahont the city. ° d Another style of bell ringer for lecomotives hss been in use some little time past on the C. P. R. R. on the locn) road from Oakland wharf to Brooklyn and Alameda. On that Toad there are three traina running continually from half-past five in the morning until halfpast twelve ot night. These trains rnn through the straets for most of tha distance. The bell ringer on those locoutotives is so arranged as to work hy steam, bnt is not connected with the rnnoing gear of the engine. A very small independent cylinder is attached to the rear end of the boiler near the cab-window, andits piston is connected ton short crank on the trunnion of the bell by means of anironrod. By this means the hell is msde toring continnonsly and at regular intervals, without reference to the speed of the engine, It can also ring when the engine is not in motion, an advantage not possessed by the othar bell ringer spoken of nbove. By so doing the bell can be rung before the engine starts np without having to handle tbe nsnal bell rope. We have often heard peopla express snrprise as to how the engineer or fireman was able to keep the bell ringing with such unvarying regularity of stroke for so long a time, when they did not know that machinery wags dnring tha work. ‘It is fonnd very convenient and advantageous, and some ‘davice of tha sort should be used ‘on ‘all local roads bnd on yard engines where there is, any . danger of‘ accident. This also is, we believe, , . How Mark Twain Got ‘‘ Beat.” Oar friend, Almarin B. Paul, tells us a pratty good thing on ‘“‘Mark Twain” as a quartz eharp, which we do not recollect ever hearing Mark say much about, in his mining axperiences. Perhaps he wae afraid of incorporating too many factsin his book, and this came to neat home to suit him. Just efter Mark returned from tha Sandwich Islands to this city, he was hard up for something to do if not, for coin; and to make a raise, concluded to do what many others ina like situation were trying to do—sell a mine belonging to afriend, Among others, he consnlted Paul on tha subject, who like all the others gave him planty of advice if nothing else. Mark's plan was to make a large interest in the mine clear. His’ arrangements went on very nicely; his descriptive and perstasive powers were irresistible, and the mine was sold. When this bappy consummation was reached, Mark, of course, expected tohave “his interest, which was not forthcoming as anticipated. It ended by his not getting the interest ‘at all. One day Paul met_hjm and askéd how it was he ‘got beatsobad."’ ‘Wall,'’ says’ Mark,‘ the faat is, I talked 80 well nnd made the feller helieve tha mine was so valnahie, that ha conldn’t help but take it all.” + Tur Satony Swecrer at Sandy, Utah, has cleaned np 11 tons of basa bniljon in 26 honrs’ Tun, 7 ' “4
