Show STAMP MILL DEVICE Local Mans Invention to Make Shoes and Dies Wear Better C L Lee fLee Gilson has Invented a worm screw w device that is calculated to great greatly ly I enhance the efficiency and wearing qualities of Shoes and dies employed ed in inthe Inthe inthe the batteries of stamp mills As every even everybody everybody body bod familiar with stamp mill practice knows It Is the hardest thing in the world to mak make a shoe or die wear down evenly As a matter of ot fact they never do wear down Aven ven en and the result is 15 that long before the shoes and anel dies arc are worn even een of their thickness the efficiency of at th s work they are expected to perform Is greatly reduced and new ones have to be bp b substituted Mr invention is a device that can an be adjusted at the top of the tho bat battery batt tery t tex frame and so connected with the battery stem that with the use of the the stem stain and consequently the shoe on its end Is kept constantly revolving Aft r the stem is released by jy bythe the cam earn and drops on to the ore are the contact comes with the stem and shoe revolving r at nt such speed Peed as the operator desires and the ore is ground as well as rushed crushed AH An parts of the shoe and the thedie thedie die di are thus called upon to perform an equal amount of work and the wear Is la distributed over the entire surface of at both loth Mr Gilson says that in addition to the th saving savin of wear and tear on shoes and dies and an increased crushing ca capacity capacity parity his invention will help to solve the problem that has long worried the theop operators op of gold quartz mills in which stamps are employed Much of the gold that is released In crushing is rusty and does not readily amalgamate because the straight drop of the stamp does noth nothing nothIng nothIng ing but release the metal from Its matrix With the grinding movement of ot the stamp which will be Imparted by his de device devicE device vice much of ot the rusty gold will be beso beso so flO burnished that the quicksilver will take hold of It I instantly Mr Gilson Is going to set up a bat battery battE battery tery tE of a couple of stamps and attach his device for illustration purposes In the near future He has applied for a patent on the invention |
