McWHORTER, '24District Manager, Goodman Mfg. Co.Denver, Colo.A glance thru the Alumni Directorywill give indication of the surprisinglylarge number of "MinesMen" that have followed the businessof supplying to the mineral industriesthe tools with which theywork. In speaking of tools I meanto include equipment and suppliessuch as hoists, rock drills, compressors,locomotives, tramways, shovellingmachines, conveyors, powder anddynamite, chemicals, and just a hostof other items up to complete mining,milling, preparation plants, smeltersand even manufacturing plants.Mechanization of the mineral industrieshas become an importantpart of it and surely the most potentmeans of reducing production costs.The technical education receivedat the Colorado School of Mines issuch that a great number of engineershas either chosen tbis mechanizationprofession or have been drawn into itby the very nature of their training.Far-thinking manufacturers interviewthe graduating class at Mines eachyear for the purpose of picking out anumber of prospective technicians andsales engineers. These interviews areinvariably done by personal contact,not by letter, reflecting the care andprudence exercised by these industriesin selecting men who are particularlywell suited for their specialty. Manymanufacturers have made tbe remark: "I don't know what it is butthere is a certain intangible somethingfound in the man from 'Mines' thathas proven to be very essential, aquality not found in men from othercolleges".CEDRIC E. McWHORTERIt is an established fact that menfrom Mines are more generouslyscattered thru the mining equipmentindustry than men from any other oneinstitution and I believe I know why.First of all, a man who enrolls atMines almost invariably reaches thisdecision only after a lot of hard,straight thinking, with a full realizationof the energy and personal disciplinerequired to complete his 4 hardyears of study. He is, therefore,already a man of purpose andequipped to make a logical decision.Success in any business demands agood generous portion of purposeand logic, better known as clearjudgment, "horse sense" or whathave you. I have heard it said by mypeople, as well as by other manufacturers,that a cross section thruthe_ graduating class at Mines invariablyshows a clean cut, energeticman who knows what he wants to doThe well worn term, "MachinerySalesman" or "Drummer" is mostsurely a misnomer. A successful miningexecutive cannot be "sold" anything.He will "buy" it if it willmake money for his company but heis too shrewd to be talked into anythingthat he does not need. Highpressure selling simply won't do. Wemanufacturers call our field men,"Sales Engineers" and we know thatour best men are those who areactually considered "consultants bytheir clients. We train them intensivelyin the application of whateverit is that we build as weli as"what makes it tick." It isn't so importantto know how a set of gearsand a motor are assembled in a machine,but it is vitally important toknow what kind of a job tbis machinewill do when applied to a particularproblem. This is why we wantand use mining engineers. Theyknow after a little experience how toanalj'ze a raining man's problem asrelated to their own particularproduct.Little need be said about the actualtechnical training received at Mines.We all know it is excellent and fullof good sound fundamentals. Ofmore importance is that when wemanufacturers get these new men wefind them already capable of applyingthese fundamentals to our specializedproblems. The old saying,"Make a start, the rest is easy" applieshere. It is important that the"Mines Man" has secured the fundamentalsof engineering and knowshow to apply them—the importantstart.I like to think that these sales engineersand technicians are performinga real service to the mineral industriesand I feel that they are. While theydo not actually produce the minerals,they keep pace with tbe needs of tbeindustry for more efficient raethodsand are constantly developing andintroducing better and safer tools.They have hundreds of thousands ofdollars in annual research expendituresback of them and they are intelligentlyapplying the results of thisresearch to the many problems ofproduction. Because of his start the"Mines Man" fits into the settingwhich the manufacturer has preparedat great expense and effort. The two,through combined efforts, produce aservice to the mineral industrieswhich has resulted in the rapid progressin civilization todaj'. Thus"Mines Men" in sales and distributionsupply tbe "tools" so necessaryfor industrial progress.Shaker Conveyors for Metal MinesThe Goodman Manufacturing Company,4834 South Halsted Street, Chicago,after nine years of intensive developmentand improvement of this system ofmechanized loading, has a line of shakerdrives which is being used very successfullyin both iron ore and copper mines.The shaker conveyor may be used solelyas a medium of transportation in mineswhich use a scraper loader for diggingand loading, or, as is the case in coalmines, it may become a digging, loadingand transporting medium combined by• Goodman Shaking Conveyor.the addition of a duckbill. The duckbillis a self-loading head which is made onlyby Goodman Manufacturing Company butis suitable for use with any make ofshaker conveyor.IN ORE MINES . , . The scraperloader has proved to be a reliable diggingunit, but, under conditions where softbottoms or long distance are involved itis much more effective and profitable toload with scrapers and discharge onto ashaker conveyor, for two reasons: (1)As the scraper drags for only short distances,its productivity is increased; (2)The shaker conveyor, having been designedespecially for the carrying of heavyloads, transports the ore continuously asfast as it is loaded.The narrow width of the troughing permitsvery close timbering. The shakertrough line may be easily and quicklymoved to a new location, ground movements.The capacity of a shaker conveyoris far in excess of most haulagesystems or systems in which the scraperdoes both the digging and the hauling. _Goodman engineers who specialize inthis type of equipment are available tomake a survey of your requirements andoffer their recommendations without anyobligation on your part."Mines Men" associated with GoodmanManufacturing Company in themanufacture and distribution of equipmentfor the mineral industries areCedric E.

Retaining dams constructedeven in freezing weather at minimumexpense and with good control atall times.Essentially the method consists of placingthe coarser tailings (usually tablesands) on the back of the dam with theBotation slimes forming a graded "pad"with the coarser materials on the face ofthe dam. This is easily accomplishedwith two pipe lines, where the table sandsare placed by the outer line and the flotationslimes by the inner. A single linemay be used by proper alternate pumpingand use of the Grigsby Spigots andGooseneck for placing the materials wherewanted.Manifolding of pumps and distrihutionof flow to the various lines are controlledeffectively with Grigsby Rubber-linedPinch Valves.Denver Hydro-ClassifierFine sizing and desliming problems, inboth cyanide and flotation, will find theirsolution in the Denver Spiral Rake Hydro-Classifier. This is an ideal unit forfurther treatment of the overflow fromother types of classifiers especially therake type, or in closed circuit with a regrindmill treating jig or flotation concentrateswhere it is essential to reducethe material to sizes —200 mesh to 10microns.Denver Equlment Company, 1400 SeventeenthStreet, Denver. Coiorado, announcestheir Hydro-Classifier.When the Hydro-Classifier is used fordesliming purposes, all particles belowany predetermined size are removed withefficiency. This flexible unit is built insizes from S' in diameter of 25 tons perday capacity to 30' in diameter of 750tons per day capacity. Even larger sizeswill be engineered for higher tonnageplants.As shown in the illustration, this Hydro-Classifier utilizes spiral rakes and theDenver Integral-Lift Worm Gear Reducer.The Denver Adjustable StrokeDiaphragm Pump permits positive controlof the underflow. This complete unitis the answer to many problems.Colorado School of Mines Men in DecoOrganization: A. C. Daman, 'IS; F. E.Briber, '16; Fred A. Brinker, '21; H. W.Kaanta, '15; E. J.
