Anni/rs, orrlewifnfiljokirliinomgf mri m nDet rmine "release the latch at such time and the piston will lower to dnmping position so that'themm terial will passthroughtheholes in-the piston and cylinder.

This invention also consists in certain other,

features of construction-andin the combination and arrangement of the several parts to be hereinafter i'ully described, -illustrated in the accompanying drawings and .zspecifically pointed out in the appended claims.

in describing the invention in detail, referenoe will be had to the accompanying drawings wherein like characters designate like or corresponding parts thruont the several views, and in which v Figure 1 is a view of the device attached to the lower end ofthe tube having a bail at its upper end. r

Fig. 2 is a longitudinal. sectional view through the device with parts in elevation. Fig. 3 is a similar view but looking to-' wards the rear'part of the clock. I

Fig. at is a longitudinal sectional view look ing toward aside of the clock. Fig. 5 is an enlarged view of the rear of the clock showing the 'arm attached to the long winding stern and also showing portions of the trip armand a part'of the spring.

Fig. 6 is a transverse sectional view'through' the piston.

Fig. 7 is a diagrammatic view of the trigger arrangement. Fig. 8 is a view of the trip arm. v Fig. 9 is a view 01": the arm ttached to thelong winding stem. r

after the parts are set as fsh'own i'n' FigsfQ and 3, the device on cylinder. lzisattached-to the tube 3 and the stem or'other material is placed in thetube and is supportedtherein by the piston 12. j The device is then lowered into the well at any desired position,'it being of course understood that the c'lock mechanism is settooperate'the trigger. at any desired time: WVhen-this time occurs, the arm 20 is moved i'romnnder the trigger bar so I nism re set'so that that the'cy'linder drops and the holes l3 thereinare in register with theholes 11 in the cylinder, and thus the material will pass l through the holes into the well. The parts are then withdrawn and the trigger mechaover again.

Attention is. called to the tact that this 'device'fwill dump its-load wherever necessary, "andit is not necessary-to lower the device to the bottom of the well, and by controlling the fdumping'by the clock mechanism the device can be positioned wherever it is desired, as sufiicient tnneis provided ffOI properlyadusting" the 'devicebefore the dumping act. 7
