The head 33 of the cylindrical slide valve is provided with ports 4I which serve as passages for the liquid charge to flow from the cylinder I I into the interior of the slide valve 34 and thence into the tail pipe 36 when the slide valve is in thetop position, as shown in' Fig. 7.

In the modication shown in Figs. 8, 9, and 10, the slide valve housing 29 and slidevalve-34 of Figs. 1 and '1 have been dispensed with, the lower end of the valve stem 3l being connected directly to the top of the tail pipe 49 of similar constructionk to' thatof thetailpipe of Figs. 1 and 7, except thatit is provided with .ports 50 just'below thepoint offattachment toy the-valve:A stem".

The method of manipulating the'two forms of" theapparatus illustratedis essentiallyfthe same as' regards the steps of chargingthe container, operating the pistonv rod `and rodlatchvmechanism, and i the f expulsion/.of the charge from: theI con.

Cleaning the apparatus after use may be accomplished by introducing a cleaning fluid into the apparatus through port 22 while the top of the tail pipe abuts the bottom of bushing I, thus opening discharge port 2l, and when the piston `is raised to the top of the cylinder. The cleaning fluid then may flow through the cylinder, discharge valve and tail pipe. i The cleaned apparatus is made ready for reloading as already described.
Among the advantages of the invention are that the liquid charge-is fully protected from contamination by fluids in the well hole; complete expulsion of the charge from the container is assured and return of charge or other uid thereinto is precluded while the apparatus is in the well; by employing a known volume of liquid in the container, the amount deposited in the well can be accurately controlled; and viscid liquids such` as some of the synthetic resin-forming liquids, e. g. phenol-formaldehyde resin-forming liquids which are dicult to place in deep wells by usual methods can be readily and accurately conveyed to the bottom of deep wells and deposited therein with the apparatus.
