Description
UNITED STATES PATENT OFFICE.
JAMES B. WAYNE AND NVILLIAM EVERED, OF DETROIT, MICHIGAN.
IMPROVEMENT IN ROCK-DRILLS.
Specification forming part of Letters Patent No. 37,652, dated February 10, 1863.
To @ZZ whom it may concern.-
Be it known that we, JAMES B. WAYNE and WILLIAM EVERED, of Detroit, Wayne county, and State of Michigan, have invented a new and useful Improvement in Machines for Stamping Rock and Crushing Ores; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a perspective view of the Inachine. Fig. 2 is a section of the lifter-stem, fulcrumcollar, lever or pincher, and anti-friction roller.
O, Figs. l and 2, is the double cam 5 P, the lever or pincher; D, the die; R, the anti friction roller; S, the fulcrurusleeve; B, the radial bar; A, the lifter-stein; N, the notch on the cam G. F is a foot on the fulcruIn-sleeve S. O is a stay-bar.
The cam C, Figs. l and 2, lifts against the roller R on the end of the lever or pineher P, thereby pressing the die D rinl y against the stem Aand carrying it upward as the cam C revolves. Upon the arrival of the notch N on the cam U at the roller R, the roller R drops into the notch N, thereby allowing the stern A to fall freely to its place. The part of the cam C then supports the foot of the fulcrum-sleeve S, and gradually allows it to descend. The cam O is then ready to repeat the operation, and give at each repetition a uniform lift to the drill.
The upward motion of the fulcrum sleeve S, Fig. 1, by the cam C, actuated by the radial bar B, gives a turning motion about its axis to the stem A, which can be regulated at pleasure by raising or lowering the stay-bar O, Fig. 1, as required, thus giving a partial turn to the stein at every revolution of the machine.
We claim- The manner of tripping the stem by means of the notched or double cams (I, thereby allowing the lever or pincher to drop, while the fulcrum-sleeve is supported and gradually allowed to descend on the cam, substantially as set forth.
JAMES B. WAYNE. WILLIAM EVERED. In presence of- GEORGE I. ROBINSON, WILLIAM G. LONG.
