WATER TUBE FOR ROCK DRILLS.
Application filed November 29, 1921.
To all whom it may concern:
Be it known that we, LEwIs C. BAYLEs, a citizen of the United States, and a resident of Easton, county of Northampton, and State of Pennsylvania, and GnovER G. TUT- TLE, a citizen of the United States, and a resident of Phillipsburg, county of \Varren, and State of New Jersey, have invented a certain ater Tube for Rock Drills, of which the following is a specification, accompanied by drawings.
This invention relates to fluid actuated rock drills of the hammer type, but more particularly to an improved water tube construction for such machines.
In a rock drill of this type, the water tube passes from the back head of the cylinder through the piston and anvil block, if one is provided, into the shank of the drill steel, and the water tube is usually provided with a nozzle at its ejecting end. The end of said water tube sometimes becomes damaged, and the object of the present invention is to construct the water tube with a removable nozzle, which may be removed as desired without removing or renewing the entire water tube.
Certain preferred constructions are illustrated in the accompanying drawings, in which- Figure l is a side elevation partly in longitudinal section of a portion of a rock drill illustrating the invention,
Figure 2 is an enlarged detail longitudinal sectional view of the removable nozzle, and
Figure 3 is a view similar to Figure 2 with the parts separated.
Referring to the drawings, only so much of a rock drill of the hammer type is shown as will serve to illustrate the invention. The portions of the machine shown comprise the cylinder A, having the front head B into which the shank C of the drill steel B extends in position to receive the blows of impact of the reciprocating piston E, delivered upon an anvil block F. A front cylinder washer G is located between the cylinder and front head B and the cylinder is provided with the plate H at its rearward end, the head block J and back head K containing a suitable distributing valve L, shown in this instance as of the oscillating Serial No. 518,638.
type. The parts of the machine casing may shown).
Water enters at the water inlet 0 and passes through the passage P to the water tube Q, which is held in the head block J in any suitable manner, as by means of the gland R and packing S and T.
The water tube Q extends through the pis ton E and anvil block F and in accordance with our invention, is provided with the removable nozzle U extending into the shank of the drill steel.
The nozzle is is provided with a nipple 0 having a peripheral groove adapted to be engaged by the hooked ends 9 of the spring fingers 1" on the water tube Q, when the anvil block F engages over said fingers.
The anvil block F has a bore of substantially the same diameter as the tube Q and thus serves to retain the spring fingers 9 about the nipple 0, so that the hooked ends 9 of the spring fingers a" will be retained in the peripheral groove 29. In the event of damage to the nozzle is so that water is prevented from being delivered into the hollow bore of the drill steel G, the nozzle is may be removed and a new one replaced. In order to remove the nozzle is, the front head B must first be removed and then the anvil block F can be removed. The nozzle is may then be withdrawn from the water tube Q and a new one substituted in its place. The anvil block not only serves as a protection for the nozzle, but also enables the water tube Q and the nozzle 7c to be securely held to ether.
e claim:
1. In a fluid actuated rock drill of the hammer type, the combination with a cylinder, reciprocating piston, and an anvil block, of a water tube extending through said piston and into said anvil block, and a removable nozzle connected to said tube and prevented from movement therefrom by said anvil block.
2. In a fluid actuated rock drill of the hammer type, the combination with a cylinder, reciprocating piston, and an anvil block, of a water tube extending through said piston and into said anvil block, a removable nozzle, and cooperating means associated with said nozzle and tube for holding said parts together, said nozzle being prevented from movement from said tube until said anvil block is removed.
In a fluid actuated rock drillwof the hammer type, the combination with a cylin- (lenreciprocating piston, and an anvil block, of a Water tube extending through said piston and into said anvil block, a removable nozzle, and spring means for connecting said nozzle and tube together, said nozzle being prevented from movement from said tube until said anvil block is removed.
4; In a fluid actuated rock drill of the hammer type, the combination with a cylinder, reciprocating piston and an anvil block, of a Water-tube extending through said piston and into said anvil block, a removable nozzle, and spring fingers on said tube adapted to connect said nozzle and tube together, said nozzle being prevented from movement from said tube until said anvil block is removed.
In testimony whereof We have signed this specification.
