APPARATUS FOR OPERATING STAMP-MILL DRIVES.
SPECIFICATION forming part of Letters Patent No. 791,732, dated. June 6, 1905.
Application led March 7,1904. Serial No. 196,996.
To all whom it may concern:
Be it known that I, ROBERT TAYLOR, a subject of I-Iis Majesty King Edward VII, residing at Subiaco, in the State of Western Australia, Australia, have invented certain new and useful Improvements in Apparatus for Operating Stamp-Mill Drives, of which the following is a specification.
This invention relates as aforesaid to apparatus for the purpose of operating Stamperbatteries, drop-hammers, pile-drivers, and other similar machines in which it is required to obtain the action of raising a battery-shank, hammer, or other weight and dropping it on the object to be crushed, hammered, or driven with a rapid succession of drops or blows, also to facilitate or impart an impetus to the drop or blow. The mechanism is'devised as a substitute for the same and other devices at present in use for a similar purpose and with the special object of obtaining a greatly increased speed in the succession of drops or blows over existing methods and appliances.
In order that my invention may be better understood both as regards construction and the method of operation, I shall now proceed to describe the same by the aid of the accompanying illustration, in which the mechanism comprising my invention is attached and adapted to an ordinary stamper-battery as at present in use for quartz-crushing and the Alike.
Figure l is a vertical side section of the -stamper-battery with thedouble-faced levercams and cooperating mechanism attached, and Fig. 2 1s a front elevation of a Stamper- -battery with the double-faced lever-cams and driving-shaft C, and bearings C', may all be similar and be constructed of like materials to those respective part-s at present in use in stamper-batteries or may be of any. other design or arrangement as is now or may be adopted byvarious makers, such materials,-
design, or arrangement constituting no part or claim in this invention. I also make use of a tappet D, as 1n use in ordinary cam-batteries, which tappets may be attached to the shank B by means of a screw, clamp, and key or by cogs and wedges, yas at present in use, and shall have a removable liner D2 attached to their wearing-faces, so that the main body of the tappet may be worn out; but when the liner is worn the latter may be replaced by a new one. In addition to this tappet B, I place a second tappet D on each shank at a certain distance below the other, the distance being in direct relation to the throw of the camlevers E. This tappet D may be similar in .design and construction and in means of atshaft by means of collars and set-screws ory some similar device. The cam-faces E2 of the lever E are made to the form of a cycloidal curve, so that whatever-position the lever may be in within its arc of action the face D2 ofthe tappet'shall be tangential to the curve of the cam-face at its highest point with which it is in contact and shall be so adjusted that when lifting the shank B the cam shall cause it to revolve in one direction, and when a cer.- tain speed of action is reached the tappet shall be thrown above the reach of thelevercams are made alike at the top and bottom, so thatthey may be reversible when worn out on IOO one face, likewise so that the lower face shall bear the same relation to the face of the lower tappet D as already specified for the upper tappet D. The back or connecting-rod end of the lever at E3 is made with an eye to which the connecting-rod F may be coupled or attached by means of a pin or bolt. A crankshaft G is fitted to the standards or columns A or to cross-bearers, as many as may be found most convenient. This crank-shaft G will have as many double cranks G as there are lever-cams to operate. They shall also be set at varying angles to each other in order to equalize the work and attain on the crankshaft as well as to obtain the correct succession in the dropping of the stampers.
Each crank G' shall be coupled to the levercams E' at the point E3 by means of a connecting-rod F, so that when the cranks are revolved the levers shall receive an alternating motion and bring the cam-faces E2 into contact with the tappet-faces D2, lift the shanks, and on returning allow them to fall.
In the event of the speed at which the levercams are driven being so great that the motion of the cams shall exceed the gravitation of the stampers the`lower cam-faces E2 will strike the top of the tappet D and accelerate its falling motion, thus increasing the impetus of the blow and avoiding the possibility of the upper tappet D dropping on the upper cam-face E2 before it has completed the drop or blow. y
rIhe crank-shaft may receive its motion from a driving-shaft C with a pulley C2, having a belt driving on the crank-shaft pulley G2, or may be driven direct by an engine or motor or by gear or by any other convenient means of power transmission. A fly-wheel Gr3 may be attached to the crank-shaft G, which by its centrifugal momentum will overcome the inertia of the stampers and equalize the strain on the driving power.
For convenience of illustrating my invention it is shown attached to a three-head battery; but I desire it to be distinctly understood that my invention may be attached to a unit battery or one of any number of stamps or heads arranged in a line, as shown in the illustrations, or the lever-cams may be constructed with a double-faced cam on each end of the connecting-rod F, coupled to a point between one end of the shaft or fulcrum E, so that one lever may be arranged and employed to operate two stamps. With this object the stamps may be arranged in asystem of even numbers back to back, or the levercams may be fitted in a position at right angles to that shown on the drawings and made to operate two stamps in the one mortar-box, the lever-cams being actuated by one crank and one connecting-rod. In a similar manner the lever-cams and mechanism may be attached to and employed for the purpose of operating drop-hammers, pile-drivers, or
such other machines in which it is required to obtain a rapid succession of dropsor blows. In all cases the cam-faces E2 being down will be some distance below the upper tappet-faces D2, and clearance shall be allowed between the tappets D and D and the guide-blocks A2, so that the action of the cam-levers E may throw the shank B some distance higher than the highest point reached by the top of the cam-face E2, also to allow for wear in the shoes and dies.
The method of operating my invention is as follows: The crank-shaft Gr being revolved by means adapted for the purpose the cranks G', through the connecting-rods F, will operate the lever-cams E', which will throw the Shanks B upward and in the case of a high speed being attained will strike the lower tappet p on the return stroke and accelerate the falling motion of the stamper or hammer or the like, thus enabling a very rapid succession of blows to be delivered on the material to be crushed, hammered, or driven, as the case may be.
What I claim as my invention, and desire to secure by Letters Patent of the United States, is-
1. In apparatus for operating stamper-batteries, drop-hammers and the like, the combination of a level' fulcrumed upon a fixed pivot and having one end formed as a double-faced cam, each of the faces being described upon a cylindrical curve, a stamper or hammer shank to one side of which the cam end of the lever passes, an upper tappet upon said shank with which the upper cam-face engages, to lift the shank and concurrently turn it, a lever-tappet at an appreciable distance from the upper, out of engagement with the cam, against which the lower cam-face may strike a blow when the lever is rapidly driven, and means for vibrating said lever.
2.
