Patented May 6,1873.

JOHN F. CARLL, OF PLEASANTVILLE, PENNSYLVANIA.
IMPROVEMENT IN PUMPS.
Specification forming part of Letters Patent No. 138,477, dated May 6, 1873; application filed February 14, 1873.
ing portion or working-barrel of a pump can be easily introduced into an old well, or be drawn out for renewal or repairs, without requiring the withdrawal of the entire line of tubing; and that it may thus be introduced or drawn out with the pump or sucker-rods without theinsertion of other or special device for doing it.
Figure 1 represents a vertical section, and Fig. 2 a transverse section, of a pump embodying my invention.
a is the lower portion of the pump-tube. b is the working-barrel, tting loosely within the tube a, and having a leather packing at c and d. The lower packing c is made to fit closely within the tube a, to steady the barrel when in place. rlhe upper packing d is tapered slightly to t into and rest upon the top of the old working-barrel, or on a surface of corresponding taper iixed at any point within the tube a, where the pump is required to work. Within the barrel b is a foot-valve, e, and the working valve or pistonf. The latter may be the ordinary cup valve, or of any suitable pattern. The upper end of the barrel bis arranged to embrace the pump-rod g, at h, for the purpose of guiding the piston and changing the working-barrel, having openings *M around the rod, as shown.
It will be seen that the barrel b, valves e and j', and pump-rod g, form a complete pump in themselves, independent of the tube a. The
latter is provided with a foot-valve, 7s, which prevents the escape of iiuid from the tube when the pump is drawn out.
In using the device, the tube a being first placed in position within the well, (or, in case of an old well, it being already in place,) the barrel b with its valves is attached to the pump-rod g, and lowered within the tube a until the packing d iits closely intoor upon its place in the tube, as shown, when the whole is ready for use.-
In casel the barrel becomes worn, or any trouble occurs in Workin g the pump, the whole device, including the barrel b and its valves, can be withdrawn from the well by drawing out the pump-rod, without disturbing the tube a.
The advantages' claimed for this arrangement are: that it can be easily introduced into any well now in operation, as a substitute for the ordinary working-barrel, or for a wornA out or defective one, without necessitating the withdrawal of the tubing; being heldin place by static pressure, no lock or screw joints are required; when the pump is withdrawn for any reason, the lower foot-valve la prevents the fluid in the tube from forcing back into the well, and thereby injuring it by agitating and forcing the dirt and sediment into the rock crevices; and any-sized pump and workingbarrel can be introduced to suit the capacity Witnesses:
