cation with the restricted outlet 17 at pleas ure. lly-operated valve 19 is mounted in the cylinder I1, and passages pipe 4 and space S, rcspectively, to the face of the said valve. A t ird passage 22 leads from the face of the valve 19.to a reserve-fluid chamber 23, in the present instance through a pipe 24. The
To all whom' it may concern.-
Be it known that I, ARTHUR H. GIBSON, a subject of the King of Great Britain, and a resident of Easton, in the county of N orthampton and State of Penns lvania, have invented a new and useful Improvement in Electropneumatic Channelers, of which the followin is a specification. I
The ject of this present invention is to manually-operated valve 19 is provided with provide certain improvements in electroa port 25, which is arranged to bring the passage 21 into open communication with the pneumatic channelers, in which the tool-piston is operated by reciprocating columns of air from a presser.
In the accompanying drawings, Figure 1' represents an electropneumatic channeler in i.
In operation when both of the spaces 8 and 9 are in open communication with their pipes .4 and the tool-piston will operate in unison with the presser-piston.
When it is desired to reduce the blow of the e elevation, a portion of the presser being s own in section, the flexible tubes between the presser and tool-cylinder beingshown broken away. Fig. 2 represents the tool-cylinder in top plan. Fi 3 represents the same in longitudinal centra section. Fig. 4 is a detail sectional view showing the manually-operatedvalve for the space at the back side of the tool-piston turned in position to bring the space into open communication with the atmosph re through a restricted outlet. Fig. 5 is a 'drlall section showing the manuallyoperated valve for controlling communication from the space at the pther side of the tool-piston either to the motive-fluid pipe or the reserve-fluid chamber, the valve being shown in position to bring the said space into open communication with the reserve-fluid chamber; and Fig; 6 is an enlarged section of the said valve.
An electropneumatic presser is shown for drivin the tool, the motor of which is denoted y 1, the presser-cylinder by 2, and its Flexible pipes 4 and 5 trunk-piston by 3. I lead from the spaces 6 and 7 at the back and the spaces 8 and 9 at front of the piston 3 to the tool-piston 10 in This piston 10 hasthe usual front rod'12 and tail-rod 13. A manuall -operated valve 14 is mounted in the cyl in e1 11, and passages 15 and 16 lead from the pi e 5"and the space 9 to the face of the said va ive. A restricted'outlet 17 also leads from the face of the valve 14 to the external atpipe 4'a nd opened to the reserve-fluid chamber 23. desirable where it is desired to ease the tool in tight places by working it up and down or to cut through difficult partswhere a hard blow would injure the tool.
In order to keep the pressure in the space 8, reserve-fluid chamber 23, and pipe 24 up to the desired ressure to accomplish the above result, it is c esirable that a valved assage be arranged in the manually-operated valve 19 through which air may leak from the pipe 4 into the'said space, chamber, and pipe, thus overcoming the reduction of pressure owing to leakage past the front rod 12. passage in the valve 19, referred to, coinprises a small aperture 19*, COIILLOIIQK by a spring-actuated valve 19**, arranged to per mit pressure to pass by the same from the pipe 4, but to close the aperture against the passage of air to the pipe 4. It will be seen that when the space S is closed to the pi e 4 the presser has to compress all of its li ting air into the pipe 4, thus raising the air to a hi her pressure than is usual and imposing a igher torque 011 the presser crank-shaft than where the tool is working in unison with the presser, but consumes no power, since the crank-shaft .re-

mosphere, and the valve 14 is provided with a I port 18, which is arranged to bring the pasceives the energy backagam after turnmgr sage 16. from the space 9 into open communi over at center.
When it is desired to dislodge the tool after cation; with the pipe 5 or into open communi tool, the space S'in front of the tool-piston 1O The valved the accompanying it has been'become jammed, the valve 14 is turned into position to cut oii communication from the space 9 back of the tool-piston to the pipe 5 and at the same time open com- 5 munication from the space 9 to atmosphere the utilization of all of t e pressure in front oi the piston. As the piston rises under this abnormalv pressure it will be prevented from striking the back'head of t e cylinder because of the restricted outlet 17 bein ,sufliciently small to cause the'air back of t e pistonto cushion it to a sufiicient extent. 7
While Ihave shown the tool-cylinder in zontally,it is to be understood that it may be used either horizontally. or vertically or at any angle desired to suit the work to be done. What I claim is Y 1. Atoolpiston,its cylinder, pipes for supplying motive site sides of the amunication etween the space at one side of thepiston and one of the pipes and open ing the said space to atmosphere. v
