',TAMP-MILL.
l Application med my 19, 1907.. serial No. 384,601.
To alliwhom 'it may concern: j Be it known that I, FRANCIS I. MAT- THEws, citizen of the United States, residing at Oakland, in the county of Alameda and- 10 crushing ore and the like.
It consists inthe combination of j arts and.l in details of Construction which Wil 'be more fully explained by reference to the accompanying drawings, in which- Figurel is afront elevation and 'partial section of my apparatus. Fig. v2 is a similar elevation taken at rightangles with Fig. 1.4 Fig. 3 isa lpersp'ective'view ofthe stamp turning devices.
an apparatus in which the maximum of crushing power may be applied, with the minimum of bulkand weight, so that such an apparatus-may be profitably employed in places where the larger and more bulky ap-v dies. lverized itpasses out through screens upon of a sing to revolve-the shaft. which in' the present case is inthe form of a paratus could not be used.-
A is a mortar'of any suitable description,A having dies 2 xed in the lower part. The/ stamp stems 3 carrying'the stam heads and 30 shoes 4 are guided and vertica ly reci rocable, so as .to crush the ore which is fed mto the mortar through a suitable inlet, and the ore thus fed passes between the shoes and When the material is sufliciently pul-` the` side of the mortar, and is receive-d in conveyers which deliver it to other parts `of the ap aratus. f
he apparatus as here illustrated consists e unit of the above description, havmg standards or equivalent supports 6.
Timbers 7 are xed transversely to these standards at suitable distances apart, .and
are provided vwith boxes '8, through which 45 the stamp stems are guided and slidable.
9 `is a horizontal shaftjournaled in boxes, as 'at` 10, and by means of a belt pulley or equivalent attachment ower is transmitted radially slotted disk 13 xed to the end of the shaft, andthe block 14 is slidable in the disk and carriesa crank pin 15 to which the u per end of' the yoke( or itman 16 is attac ed.

It is'the object of my invention to provide T is shaft has a crankA @atented *.T une 23,11908.
moving the crank pin to or from the'center of revolution. It will be manifest that any suitable or desired form of crank or recipron cating device may be employed at this point, but the above device allows forreadyadjustment of the length of the stroke.
The lower end of the pitman yis connected with a wrist-pin 17,by mechanism to benereafter described. This wrist-pin is fixed to and projects from the sleeve 18, through which the stamp stem 3 passes loosely. 4Collars 19 are fixed to the stamp stem above and below the sleeve 18, and these collars retain the sleeve in a fixed position with relation to the stamp stem, the latter being freely turnable within the sleeve by means to be hereafter described. The connection ofthe pin 17 with thissleeve, and the actionof the crank and pitman serve toreciprocate the stamp stem, and to cause the stamp to rise and fall atany desired rate of speed.` In order to connect the Apitman with the wrist-pin, and to apply a force much greater than the .normal weight and meinem tum of the stamps would produce, I have shown the following connection: The pitman 16 carries a table'orarms 2(),-which are here shown as projecting uponv each side, and upon these arms are mounted the stiff springs 21. Holes are made through the table or arms 20 in line with the axis of the spring, and rods 22 extend through these holes from the top of the spring down to a point .of attachment be? low, to be hereafter described. Upon the top of each spring 21 is 'a plate 23, and the rods 22 passing through these plates and bem screw-threaded at the upper end, receive sultable nuts 24 which may be screwed down so as to compress the springs 21 upon the `plate 20 with .any degree of force.
25 are suitably curved arms having their inner ends'hinged or pivoted to the pitman 16 by pins, as shown at 25a. 'These arms are here'shown as curving downwardly, and
their lower ends divergent from the central line. These lower ends are provided with journal boxes 28, as shown. Links 26 have their outer ends mounted in these journal boxes, and the inner ends ysimilarly connected with the head or part 27, which connects the wrist-pin 17, and through which connection is made with the stamp stem 3. at the inner and outer ends of the lin s 26, thus supported in bexes, will allow fan oscillating movement of thepins with the least possible wear. Hard wood boxes are very The` ivots suitable for such conditions, but any material that may be found suitable may be em ployed at these points. These radial rods or inks 26 thus connect the lower ends of the arms 25 with the stamp stem and prevent their being separated about theirl ulcrum points 25a by the tension of the springs.
The lower ends of the spring tension rods 22 are engaged with boxes or sockets on the arms 25, as shown at 29, so that they exert an upward and downward pull upon the arms 25 by reason of the tension of the springs 21 which, as before described, may .be made as great as desired; and this upward pull is resisted by the radial links 26 connecting with the lower ends of the arms 25.
The operation of this portion of the apparatus will then be as follows: Power being applied to rotate the crankshaft, the. crank wil act to reciprocate the pitman 16, and through the arms 25 and links 26 an elastic movement is transmitted to the wrist-pin 17 and stamp stem 3. The inertia caused by the weight of the moving lparts will act to compress the springs 21 when the crank moves upwardly, this compression being producedby the pull-upon the pitman 16 through its connection with the stamp stem, and this pulling down upon the radial links 26, acts correspondingly to pull the arms .25 downward, turning about their pivots 25a; and this movement acting through the rods 22- upon the springs 23 compresses the springs. On the dovmward lmovement of the crank and pitman the reverse action takes place,
the springs being relieved and allowingthe links orl arms 26' to first arrive at vtheir normal position in a substantially straight line; then the further downward movement of the crank and the inertia of'the stamp causes the inner ends of the links to be temporarily moved upwardly, and the same compression of the sprin s takes place. The tension of the springs t us alternately applied after the inertia of the stamp hasfbeen overcome will impel the stamp with increased power, and
with a stroke considerably in excess of that of the crank. Thus'with a crank movement of five inches, a movement of the stamp stem of substantially eight inches maybe effected by reason of the alternate up and down vibrations of the links 26, and the springs being com ressed at each reciprocation will exercise t reir power to act upon the stam The result of these actions is first to enab e thestamp to be run et a high rate of speed, and by reason of the alternate compression and ex ansion of the springs an exceedingly heavy low may be struck, far in excess of any blow that can be struck by mere gravitation of afalling stamp, while the rate of speed with which the blows `can be struck is only limited by the strength of the springsand the ability of the moving parts to resist the strain upon them. l
For the purpose of revolving the stamp stem duringits reciprocation so as to continually presentY new surfaces of the stamp \as it falls, I have shown a spiral groove and an engaging tongue, one being formed in the stem 3, or preferably on a sleeve 3L carried by the stem,'and the other in an' inclosing collar 30, through which the stem and sleeve are slidable. In the present case the spiral groove isshown formed upon the sleeve which is fixed tothe stem, and the engaging tongue 31 inthe collar.
The collar is freely turnable in a box or sup ort 32 carried u on the upper guide 7, ass own, and the co ar has projecting teeth 33' surrounding it, which are engaged by spring pressed pawls 34 carried in the sockets in box 32, so that their inner ends are constantly pressed against the ratchet teeth 33. While one of said awls may be operative, I prefer to use a p urality of such pawls lolcated in suchpositions that they engage the teeth of the ratchet approximately e uidistant from each other, and so dispose that lone opposed pair of the pawls will be engaged withthe teeth of the ratchet, while the other pair are intermediatev of the holding positions and ordinarily moving over the teeth-of the ratchet. f Four such pawlswill produce this resultf'w Consequently, the movements of the stem will alternately engageone opposed pair of the pawls and then the other. The reci rocation of the stamp stem through the col ar and the action of the s iral groove will turn the collar freely in one lrection, referably while the stamp is rising, thus a lowing the stamp to rise directly with no undue friction; and when the stamp falls, the 'action of the spiral will cause the pawls and the teethA to engageso that the stampstem will be rotated by reason of the collar being temporarily locked.
There is always considerable wear in the guide boxes on account of the continuous reciprocation of. the stem throu h them, and in order to prevent the parts a ove described from getting out of alinement, I have shown a connection consisting of a link 35 connecting a lug 36 on the casing with a sup ort 37 of the frame. The bolts bywhich t e part 32 is connected with the frame pass through holes which are sufficiently enlarged to allow a free movement of the member or casing 32 with relation to the frame, 'and the connection causes these movements to be made in unison with those of the stamp stem, so that if the latter shouldget out of alinement with the frame or move irregularly, due to wear` fend.- ofr' the stamp stem to receive the stamp head or the spiral groove sleeve 3?; thus .being tapered in parts,
when the. stamp stem is iirstfused, one end y the usual manner is locked with the stamp head which carries ,the stamp atthe lower end, while the upper end has the l sleeve 3 secured to it.
If at any time it is desirable to reverse the stem, it is only necessary to disengage it from the stamp head and the sleeve, reverse it,'\ and re-connect the ends 'with the relative Having thus described my inventionwhat I claim. and desire to secure by Letters Pat- 1.
