STAMP AND ROLLER CRUSHER AND PULVERIZR.
SPECIFICATION forming part of Letters Patent No. 633,248, dated September 19, 1899.
Application filed July 12, 1898. Serial No. 685,756. (No model.)
To all whom t may concern:
Be it known that I, ADoLrH JOHN PE'rTER, a citizen of the United. States, residing at Randsburg, county of Kern, State of California, have invented an Improvement in Stamp and Roller Crushers and Pulverizers;
and I hereby declare the following to be a full, clear, and eXact description of the same. My invention relates to an apparatus which 'is especially designed for crushing and pulverizing ores of precious metals, either wet or dry, and also for amalgamating.
It consists in the parts and the constructions and combination of parts hereinafter described and claimed.
Figure- 1 represents a vertical section through my machine. Fig. 2 is a sectional view, on a reduced scale, von the line .fr m of Fig. 3. Fig. 3 is a plan view. Fig. lis adetail showing a rear view of one of the pinions 13 with its cam 14 and showing also the shaft 17 and tappet-cam.
The object of my invention is to combine vertically reciprocating stamps with rolls which travel upon the dies of the mortar, so that the material is subject to the sweeping or oblique impact of the falling stamps and the horizontal dragging, rubbing, or mullerlike motion of the stamps and conical rolls.
lis a circular mortar or chamber having suitable anges by which it is secured to the mortar-block 30. This mortar-block contains a ring or series of dies 2, arranged in a circle, and the stamps 3 are fixed upon vertical stamp-stems and adapted to rise and fall when the machine is in operation, so as to pulverize any material which is delivered into the mortar and upon the dies through a feedhopper 23 or by other method.
The stamps are mounted in a movable upper framework or support 7, which is revoluble by means of belt or other connection to the belt-pulleyor its equivalent driver 38, and this motion during the rise and fall of the stamps produces a glancing oblique sweeping stroke of the stamps, which greatly increases their pnlverizin g capacity. The bottom plate of 7 is supported upon an antifriction-bearin g, herein shown as including balls 8, which fit in suitable runways 9, so that the upperportion of the apparatus is carried upon these balls, thus enabling it to turn easily.
29 are felt or other flanges, which fit over the joints between the stationary mortar and movable upper part to prevent dirt from entering the bearings on the inside and to prevent the pulp or dust escaping outside. This upper part- 7 carries vertically-movable standards 6, which are slidable in guides and which are pressed downwardly by springs 21, the upper ends of which abut against the caps 20. These caps are fitted to bolts 19, fixed in frame 7 and having nuts upon the upper ends, and by screwing these nuts down the tension of the springs 2l is increased and the pressure through the standard 6 is correspondingly increased. The lower ends of the standards 6 carry shafts which are rotatable with relation thereto. Upon the ends of these shafts are the conical rollers 4t, the faces of which run upon the dies 2. The faces of these rollers converge outwardly, and the incline of the shafts corresponds, so that the faces will roll upon the dies with the couvergent ends outwardly instead of inwardly. Therefore it will be understood that as they roll upon the dies they will also produce a rubbing or grinding' action which increases the capacity of the apparatus for work. As previously described, the pressure of these rollers upon the diesis increased by screwing down the caps 2O and increasing the tension of the springs 2l, so that a greater portion of the weight of the upper part of the machine may be brought upon the rollers. Fans 2S are carried by the rollers, and these act to force the pulp outwardly and through the screens 27 when it is fine enough.
A is a fan driven by a pulley or equivalent device H, carried by the gear 13. Airfroin this fan enters the circ ular pipe F and escapes therefrom through holes D and serves to blow the pulp or dust oil" the dies and out through the screens.
l1 is a vertical central shaft passing down through the machine and having its Ylower end fitting in a step 25. This shaft has keyed to it a bevel-gear 16, which engages withthe teeth of bevel-gears 13, the shafts of which are journaled horizontally in the framework 7, as shown. These shafts 17 extend to one side of the stamp-stem 3 and have cams 1S lixed to them in such a position that the cams will engage with tappets 34 and raise Athe IOO stamps, allowing them to drop whenever the cams have passed the tappets.
It will be seen by this construction that when the upper part of the lnachine is revolved by the pulley or other device 38, as previously described, the stamps, with their stems and tap pets, and the shafts 17 and gears 13 will be revolved around the central vertical axis or center of the machine, and as the gears 13 engage with the teeth of the stationary gear 16 it will rotate the gears 13 and their shafts, and thus cause the cams to alternately raise aud drop the stamps.
The central shaft 11 passes through a socketpiece 10, the lower portion of which is fluted and fits within the runway 9, in which the balls S are carried. This socket-piece is connected with the vertical shaft 11 by a key 12, so that the two are stationary, and as long as the socket 10 remains seated within the runway 9 it retains the shaft 1l and its gear 16 iu a stationary position, and the revolution of the upper portion 7 of the machine acts upon the stamp and grinding-rollers, as previously described. The keyway extends to the bottom of the shaft, and this allows it to be lifted out from the top and the machine dismembered.
It is desirable to cause the stamps to drop at different points on the dies 2 to prevent their wearing into depressions, as would be the case if they always fell at the same points. I have therefore shown a lug or cam 14 either cast with the gear or fixed to turn with the shaft 17, so as to engage the outer end of the lever 15, which is fulcrumed upon the framework 7. When the lug thus engages this lever,the inner end of the lever rises up under the flange of the socket-piece 10 and lifts the socket-piece 10 and lifts the socket out of its engagement with the runway 9. This temporarily frees the socket 10 and the central shaft 1l and allows them to turn'a little way until the cam 14 releases the lever 15, when they will drop back, the socket engaging the runway, as previously described, and again holding the parts stationary. This change of position insures the falling of the stamps upon a new part of the die at each time when thechangeoccurs. The fiutingsinthesocketpiece and those in the corresponding ring are tapered and pointed, as shown, to insure the parts engaging easily when the socket-piece is again let down.
It is sometimes desirable to raise the stamps to such a height that the tappets will not be engaged by the cams 18, and this is effected by a yoke or spider 33, the arms of which engage with collars 32, fixed upon the outerends of the stamp-stems. A swivel-ring 36 is connected with the center of the spider, and by means of a block and tackle of any suitable description these parts may be lifted to any desired height. If the apparatus continues in motion under these conditions, the rollers will continue to grind the ores upon the dies, while the stamps will bevout of action.
22 are flanges extending beyond the peripheries of the bevel gear- wheels 13 and 16, so that they run in Contact, and this insures the teeth of the gears meshing to prevent them from being forced together or becoming jammed by the weight of the upper part of the machine.
K K are channels through which waste oil is discharged and prevented from entering,r the mortar.
The peculiar sweeping grinding motion of the stampsy and the outwardlyconverging rollers greatly facilitates .the amalgamation of free milling ores by its scouring and polishing action on the metal.
The devices here described are very satisfactory for carrying out the principles of my invention; but I do not wish to confine myself to its special mechanisms,as various modifications will suggest themselves to those skilled in the art without departing from the spirit of the invention.
Having thus described my invention, what I claim as new, and desireto secure by Letters Patent, is-
