TQ ALL WHOM IT MAY CONCERN:
Be it known that I, JOHN SQUIRE STOCKHAM, of Red Dog, county of Nevada, State of California, have invented certain new and usefullmprovements in Rock-Drilling Machines, and I do hereby declare the following description and accompanying drawings are snicientto enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvements without further invention or experiment. i
My invention relates to machines for drillingr rock, and consists in providing an improved mechanism for directing the drill toany desired point, and also for giving more etective blows, especially in confined places where a sledge could not h'e used to advantage. This object is attained by constructing a double frame or any convenient mechanism by which a universal joint is obtained, so as to allow the drill to be pointed in any direction. The drill-stock extends longitudinally across the frame, and has a tappet fixed to the back part of it, behind which is a spring sufficiently stii` to force the drill forward and give the desired blow ias soon as the tapp'et is released by the earn. The cam-shaft crosses theframe transversely, and has a cam soplaced as to operatethc tappet, cranks being fixedI at each end by which to turn it. By means of a hand-wheel the drill may be fed forward through the tappetas fast as necessary. Arcs with set-screws or other devices may bc used to retain the frame in position after-it is set. i
.To more fully describe-my invention, refcrence is had to the accompanying drawings, forming parts of this specification, of which- Figure 1 is a side sectional elevation.
Figure 2 is a plan.
Similar letters indicate like parts in each of the drawings.
In .the accompaning drawings, A is a base-plate, having the upright standard B. A pin or bolt, C passes through the horizontal part of this standard, on which it turns, thus giving any desired motion to the drill from side to side. The frame D is hinged to the upper ends of B, so that it will move in a `vertical plane, and, by combining the motions, any desired angle may be attained. E is the drill-stock, having the drill H in one end of it. The istock is supported and slides in boxes at the end of the frame D. F is a tappet on the stock E, moving on ascrcw cut on the stock, and by this means allowing the drill to be fed forward as fast as is necessary. Thespring G is placed back of the tappet, resting between it and the back of the frame. The cam I is supported and turned by the shaft K, which may have cranks Il upon each end by which to operate it.
When the machine is to be operated it is moved up to the rock, and the supporting-frame turned either up, sidewise, or-down, so that the drill will operate on the rock at the desired point. The frame is then set or fastened and the cranks turned. The cam presses the tappet back and compresses the spring, which, on being released, impels the drill against the rock'; the drill will be turned around by thecam operating on the tappet each time. In this manner a man or two men can do much more work with a less expenditure of power than where a sledge is to be used, while the drill ean`he used to advantage in places were it would be impossible to use an ordinary drill.
Having thus described my invention; what Iclaim, and desire to secure by-,Letters Patent, is
The drill, constructed with the drill-rod E, the tappet F, spring G, and cam I, operating within thc swingingframe D, supported by standard B, for giving universal motion, substantially as described.
In witness whereof I have hereunto set my hand and seal.
