IMPROVEMENT IN 'l'RlPODS FOR ROCK-DRILLS Specification forming part of Letters-Patent No. 174,352, dated March 7, 1876 application tiled October 13, 1875. I
To all whom it may concern Be it known that I, LAWRENCE W. 00E, of Auburn, Cayuga county, State of New York, have invented an Improved Tripod for Supporting Drills, and I do hereby declare the following description and accompanying drawings are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvement without further invention or experiment. I
My invention relates to certain improve ments in the stands or tripods which are employed to support rock-drills while they are working; and it consists in a novel construction of the joints of the two side legs, by which I am enabled to make the movement of these legs almost universal, and thus place the drill in the most advantageous position for work,
. while, from the peculiar formation of the joint,
no projections appear above the level of the cylinder or shaft to which the drill is secured. Referring to the accompanying drawings for a more complete explanation of my invenare each hinged, at e, to a plate, F, so that they have a lateral motion, whilethe plates 1*" are perforated so as to receive the axis of the cylinder A, around which the plates may be turned, and this motion, combined with the lateral motion of the legs from the plates F, will allow the legs 0 to be put in any position which may be desired, even to bracing them against the side or face of the tunnel or rock which is being drilled. The plates F are flush with the top of the cylinder, and, as there are no projections above it, the drill may be moved in any position unimpeded.
The peculiar construction of the joints of the legs allows them a freedom of motion which never can be obtained by a ball-andsocket joint, and, as a consequence, drills mounted upon my tripod can be worked to axis of the cylinder A, and having the legs 0 hinged to them so as to have alateral motion, the whole combined to operate substantially as and for the purpose herein described.
