Specification of Letters Patent.
Patented Marl 3', 1914.
Application filed February, 1912. Serial No. 675,292.
To kill whom t may concern Be it known that I, Liiwis C. Barnes, a and resident of in the county of Northampton and State of Pennsylvania, have invented a new and useful lImprovement in Percussive Tools, of which the following is a specification.
rI he object of this invention is to provide a novel form of automatic rotation device which will be very simple and compact, which rotation device is under the control ofthe valve which controls the operation of the tool.
In the accompanying drawings, Figure 1 represents in longitudinal central section a percussive tool with my improved rotation device applied thereto, Fig. 2 is a transverse section taken in the plane of the line .Li-A of Fig, 1, Fig. 3 is a transverse section taken in the plane of the line B-B of Fig. 1, 4and Fig. 4 is a diagrammatic view showing more clearly the construction of the controlling valve, its chamber and the passages leading therefrom to the work piston chamber and the rocking piston chamber.
The work piston is denoted by 1 and the chamber within which it'reciprocates by 2. The tool cylinder is denoted by 3,. its front head by 4, the front head -washer by 5, the back head by 6, the rocking piston chest by 7, 8, and the handle, of usual form, by 9, which handle contains the usual oil supply chamber 9*.
The pressure fluid operated rocking piston is denoted by 10 and the chamber within which it oscillates by 11. yThe valve 12 which controls the operation of the work piston 1 and rocking piston 10 is situated in a valve chest 13.
The drill steel shank is' denoted byl 14 and Easton,
'its chuck by 15, which chuck is rotatably mounted in the front head 11 and has anl enlarged bore 16 into which the rear end of the drill shank 14 extends in position to be struck by the extension 17' of the work piston 1. l
`The oscillating rocking piston 10 is vfixed :tothe rear end of a rock shaft 18 which `ei:-
tends longitudinally from front to rear of the toolthrough the cylinder 3, The Jfront end of this rock shaft 18 is extended into the front head 4 and has a driving connec-I tion with the chuck 15 whereby the rocking movement of the shaft will impart a step by step rotary movement in one direction to the chuck. This driving connection is shown h erein as a pawl and ratchet clutch connection, the ratchet 19 being on the chuck 1,54
and the spring pressed pawl 20 being car'- ried by a collar 2]ixed to the shaft, 18.
The valv'e 12 herein shown is of the well known double winged type, one wing controlling the inlet passages 21, 22, leading to the ends of the work piston chamber 2 and the inlet passages 25, 26, leading to the opposite sides of the rocking piston chamber 11, the other wing controlling the exhaust passages 23, 24, leading to the work piston chamber 2 intermediate the inlet passages 21, 22. It will thus be seen that the valve 12 controls the movements ofthe work piston 1 and the rocking piston 10.
It will be seen that the rotation device, as herein shown and' described, isa very simple and compact one.v i
While I have shown this rotation device as applied to a pressure fluid operated per'- cussive tool of the piston hammer type. 'I do not wish to limit myself to such application but contemplate its use in connection with percussive tools of any type.
1. In a percussive tool, a chuck and means for rotating it comprising a rock shaft, a fluid pressure operated rocking piston carried thereby at the rear of the tool and a driving connection between the shaft and chuck.
2. In a percussive tool, a chuck` a rock shaft, a fluid ressure operated rocking;` piston, carried t ereby at'the rear of the tool, and a clutch connection between the shaft and chuck.
3. In a percussive tool, a chuck and means for rotating it comprising a rock shaft extending longitudinally from front to i'ear of the tool, a fluid pressure operated rocking piston fixed -to the shaft at the rear of tending longitudinally from front to rear of presence of two witnesses` this first day of the too, aduid lpressure operated rocking February, 1912. piston Xe to the shaft :it the rear of the f L -f tool and a clutch connection between the LEWID C' BlLEb' 5 Shaft and chuck at the front of the tool. Titnessesz In testimony, that I claim the foregoing F. GEORGE BARRY, 'as my invention, I have signed my name in C. S. SUNDGREN.
