Description

Patented Oct. 2, 1928.
UNITED STATES GEORGE A. SPANG, OF BUTLER, PENNSYLVANIA.
COMBINED BAILER AND JAR.
Application filed January 12, 1923. Serial N o. 612,250.
This invention relates to bailers for use in well drilling by the cable system.
In well drilling by the cable system, it is necessary to use a bailer of some description and it is very common for the bailer to stick in the well hole.
When the bailer sticks, various devices are resorted to by the driller to remove the bailer, but so far as I know, none now in use are as satisfactory as might be desired.
Ordinarily, the driller first attempts to jerk the bailer out by leaving slack in the line and then jerking as the line straightens. This is hard on the line, since the space is small within which the slack line can coil. It
also rubs on the wall of the hole and often kinks.
The second method ordinarily tried if the one above outlined fails, is to cut the line by means of a rope knife, and then attempt to ar the bailer out of the hole. This is done by taking hold of the bailer by means of a boot or latch jack attached to a set of jars,
a drilling stem and a rope socket.
It often happens that the bailer is so tightly fastened in the hole that in attempting to jar it out by the second method above outlined, the bailer bail will be cut in two by the jarring operation. Often when this happens, the driller goes to the trouble of making special tools to take hold of the cut or split bailer bail.
It often happens that both of the above methods fail and that the only possible way of removing the bailer is to drill the same into fragments by means of the drilling tools, so that the bailer and its contents can be removed from the hole.
An object of this invention is to produce an organized or integral device comprising a'bailer and a jar by means of which the bailer, if it becomes stuck in the hole can immediately be jarred outwithout loss of time.
tially in section and partially in elevation This object, as well as others which will of a combined bailer and jar embodying this invention. Fig. 2 is a sectional view of the upper part of the bailer and jar illustrated in Fig. 1, taken at right angles to the view of Fig. 1 and Fig. 3 is a view in perspective of the bailer bail.
As shown in the drawings, the bailer 4 which may he of any suit-able construction, is provided with a bottom valve 5 and a bail 6. Linked Within the bailer bail 6 is a link like element 7 to the upper end of which the line 8 is connected. A guide rod 9 projects downwardly from the element 7 and at its lower end is provided with guide members 10 which co-operate with a ring 11 secured in position within bail 6 to maintain link element 7 in operative position or in axial alignment with the bailer.
It will be seen that the lost motion connection formed by the bailer bail and the linklike member 7' constitutes a jar.
In operation, the driller can start to jar the bailer out the instant it becomes stuck in the hole. This is of great advantage, because ordinarily the longer a bailer remains in the hole after once sticking, the tighter it becomes. This is so because material breaks awa from the walls of the hole and wedges the ailer in place. In this device, the jar is always in operative position ready to be used the instant it is needed.
While I have described but one embodi ment of my invention, it will be apparent to rious changes, omissions, additions and substitutions may be made in=the device illustrated Without departing from the spirit and scope of the invention, as set forth by the appended claim.
I claim The combination with a bailer having a hail, of a link adapted to co-operate with said bail so as to'form a jar, a collar secured to said bail, a rod on said link extending into said bailer through said collar, and means on said rod for aligning it with said collar so as to guide the movement of said link.
In testimony whereof, I have hereunto subscribed my name, this third day of J anuary, 1923.
' GEORGE SPANG.
