Definitions
- This invention relates to fluid actuated percussive tools but more particularly to a rotating connection for imparting rotation to the drill steel.
- the objects of the invention are to improve upon the rotation connections for such tools and to produce a small, light and compact front end for the tool, which permits the rotation motor and its operative parts to be more readily mounted rearwardly of the front end instead of at the front of the hammer cylinder. This is especially advantageous in stope drills, in which a heavy front end is particularly undesirable because the front end is usually raised at an elevation.
- Another object of the present invention is to produce a tool which is free from exterior projections at the front end so that the outside of the casing is as smooth as possible.

ROTATING CONSTRUCTION FOB PERCUSSIVE TOOLS.
Specification of Letters Patent.
Patented Apr. 19, 1921.
Application filed. March 22, 1920. Serial No. 367,833.
To all whom it may concern:
e it known that I, Lnwrs C. BAYLEs, a
citizen of the United States, residing at Easton, in. the county of Northampton and State of Pennsylvania, have invented a certain new and useful Improvement in R0- tating Constructions for Percussive Tools, of which the following is a specification.
This invention relates to fluid actuated percussive tools but more particularly to a rotating connection for imparting rotation to the drill steel.
The objects of the invention are to improve upon the rotation connections for such tools and to produce a small, light and compact front end for the tool, which permits the rotation motor and its operative parts to be more readily mounted rearwardly of the front end instead of at the front of the hammer cylinder. This is especially advantageous in stope drills, in which a heavy front end is particularly undesirable because the front end is usually raised at an elevation. Another object of the present invention is to produce a tool which is free from exterior projections at the front end so that the outside of the casing is as smooth as possible.
The invention is illustrated in one of its preferred forms in theaccompanying drawings in which- Figure 1 is a side elevation partly broken away and partly in longitudinal section of so much of a percussive tool as will show the invention,
Fig. 2 is a transverse sectional view on the line 22 of Fig. 1, and
Fig. 3 is a transverse sectional view on the line 33 of Fig. 1.
Referring to the drawings, Arepresents a cylinder casing in which a piston B is adapted to reciprocate, actuated by suitable means as for instance motive fluid. The connections for supplying and distributing the actuating motive fluid are omitted as not forming a part of the present invention.
A suitable front head 0 is adapted to be secured to the cylinder casing in the usual manner as by means of the side bolts D indicated in Fig. 2. The drill steel E is adapted to be held in a rotating chuck F within the front head C, and a rotation sleeve G is also mounted within the front head and provided with lugs or extensions H engaging recessed portions J formed in the rotating chuck F so that the rotation sleeve G and chuck F rotate together. The rotation sleeve G is preferably provided with a flange K adapted to be seated between a recessed portion L of the cylinder casing and the inner end of the front head Q to maintain the rotation sleeve in operative position in the tool.
The rotation sleeve G is preferably hollow and within the sleeve is placed an anvil block 0 adapted to bear upon the drill steel E The rotation sleeve G also forms a holder or carrier for the tappets P which extend through the sleeve and bear upon the anvilblock 0; These tappetsare adapted to be struck by the piston B and transmit the impact through the anvil block 0 to the drill steel.
Rotation is imparted to the rotation sleeve G by means of a rotating shaft Q, extending through the piston B and provided with a squared end R engaging the socket S in the head of the rotation sleeve G. Any suitable means not shown may be provided for rotating the driving shaft Q, but if this means comprises an independent rotation motor it is obvious that the motor may if desired be located at the back end of the tool or in any other convenient osition rearwardly of the front head. Cleaning fluid may be supplied to the drill steel through the water pipe T in the usual manner.
I claim a 1. In a percussive tool, a cylinder, a piston reciprocating therein, a front head, a chuck in said front head adapted to receive the drill steel, an anvil block, a rotation sleeve engaging the said chuck, a rotary shaft passing through the piston and connected to rotatesaid rotation sleeve, and at least one tappet slidably'mounted in said rotation sleeve and adapted to receive and transmit the impact blow of the piston.
2. In a percussive tool, a cylinder, a piston reciprocating therein, a front head, a chuck in said front head adapted to receive the drill steel, an anvil block, a rotation sleeve engaging the said chuck, a rotary shaft passing through the piston and connected to rotate said rotation sleeve and tappets slidably mounted in said rotation sleeve and adapted to receive the impact of the block.
3. In a percussive tool, a'cylinder, a piston reciprocating therein, a front head, a chtiekin saidfront head adapted to receive the drill steel, a rotation sleeve engaging said chuck, an anvil block ithin the rotation sleeve, tappets slidably mounted in said rotation sleeve and adapted to bear upon the anvil block, and a rotary shaft passing through the piston and connected to rotate the said rotation sleeve. 10
i In testimony whereof, I have hereunto set my hand.
LEWIS C. BAYLES.
