JOSEF BREJGHA, OF STRASBURG -NEUDORF, GERMANY.
APPARATUS FOR RlNSING THE CORES OF ROCK-DRILLING MACHINES- SPECIFIGATION forming part of Letters Patent No. 766,588, dated August 2, 1904.
Application filed July 15, 1902. Serial No. 115,718. (No model.)
To (all whom 712? may concern:
Be it known that I, JosEF BREJCHA, a subject of the Emperor of Germany, residing at Strasburg- Ieudorf, Alsace-Lorraine, Germany, have invented certain new and useful Improvements in Apparatus for Rinsing the (.ores of Rock-Drilling Machines, of which the following is a specification.
My invention relates to an apparatus for rinsing and washing the cores of rock-drilling machines in the course of the boring. The force-water comes from without through the cutter to the drill-stock and presses out the bore-hole grit with the cores, preventing through it the jamming of the cutter. The water operates in course for the movement of the cores, and the drill-stock is perfectly round and is let open in its rear end.
A form of construction of the object of the invention is illustrated by way of example in the accompanying drawings, in'which- Figure l is asection through the apparatus. Fig. 2 is a front elevation of it witha section through the rear end of the drilling-machine.
A case is seated on the hollow drill-stock a, closed water-tight by two rings g f, of caoutchouc or other material, and possesses a water-tube a. The ring 9 secures the force-water entering through the pipe 0 from running out of the case b, and the ring fis pressed to the rock in such a manner that the coming in of the water into the bore-hole is done without loss. The cutter i has a larger diameter than the drill-stock andis supplied with chamfers i through which the Water can come to the interior of the drill-stock. The
case 6 is braced by an arm (Z, which can be removed In a tube 6, fixed on the frame of the machine by means of a worm with a nut p.
The water gets through the water-pipe Z and the tube a to the case 5, comes through the ring fbetween the drill-stock and the rock through the chamfers I of the cutter a: to the interior of the hollow drill-stock a, and presses the cores m, with the bore-hole grit, through the drill-stock, open in its rear end, preventing through it the jamming of the cutter.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
1. In a rock-drill, the combination with a tubular drill-stock, a casing carried by the drill-stock and bearing against the surface to be drilled and means interposed between said casing and the drill-frame for moving said casing forward, said means comprising a rearwardly-extending arm carried by the casing, a socket on the drill-frame for receiving said arm and means carried by said arm for moving the same forward, substantially as described.
2. In a rock-drill, the combination with a tubular drill-stock, a casing carried by the drill-stock and bearing against the surface to
