- An object of the invention is to provide a well tool of the character` described adapted to' be lowered into 4a pipe which is located in a well bore and which is operative to punch a bushing through the pipe. `This bushing is provided with a ilow channel, orforice, therethrough through which uid may enter the pipe.
.It is, at times, desirable to introduce pressure fluid into the well tof assist in the flow of the well fluid through` the well tubing and when this becomes necessary the tool herein described may be lowered to the desired location and the bushing punched through the pipe to provide for the inflow of the pressure fluid and, if desired bush ings maybe inserted at diierent elevations for the introduction of this pressure uid.
It is another object of the present invention to provide a tool of the character described which is composed of few movable parts, the essential movable, parts being the bushing itself and an explosive actuated plunger for forcing the bushing through the pipe.
It is a further object of the invention to pro- Y vide, in a tool of the character described, means for quickly relieving ,the pressure generated by the explosion upon insertion of the bushing through the pipewall.
A further object of the invention resides in the provision of a novel Atype of bushing which may be effectively punched through the pipe but which cannot be displaced and which is formed of' hard, wear resistingmaterial so that it will not be readily cut out by the iniloiv of gritty duid therethrough.
The invention also embodies novel means for anchoring the tool at aselected place in the pipe.
Other objects and advantageswill be apparent from the following specification which is illustrated by the accompanying drawings wherein:
vFigure 1 is a vertical, sectional view oi the upper endof the tool while being lowered into a well pipe. Y
Figure 2 is a vertical,.sectional view of the lower end thereof. Y,
Figure 3 is a cross-sectional view takenon the line 3-3 of Figure 2.

Figure 7 is a vertical, sectional, view of the lower end of the tool as shown in Fgure.
Figure 8 is an enlarged, longitudinal, sectional View of the oriiee bushing in the well tubing, and Figure 9 is an end View of the bushing. Referring now more particularly to the drawings wherein like numerals of reference Adesignate similar parts in each of the figures, the
numeral i designates a cylindrical body having Within this barrel there is aplunger 3 whose inner end fits snuglyu a radially extended barrel 2.
in the barrel but whose outer end is slightly reduced in diameter thus forming an externalA annular shoulder i around the plunger.
Within the outer end of the barrel there isan annular groove 5 and a snap ring 6 is locatedin this groove and forms a stop aga-instwhich the shoulder i engages to limit the outward Inove-` .ment of the plunger.
Secured to the outer end of the plunger there is a bushing "l which has a passageway 8 extendinglongitudinally therethrough. Thisv passageway, or channel, t may be of any selected transverse diameter and the bushing is formed of hard wear resisting material so thatit will not be readily cut out and enlarged by gritty iiuidl ilowing under pressure therethrough. i v
Any selected type of bushing may be usedb-ut what is now considered a preferred form of the bushing is shown. It is reduced in external diameter at its outer end and formed with the annular cutting edge 9, this reduction forming an external annular shoulder l0 near `the outer end of the bushing. It has been found in practice that this type of bushing will more readily penetrate the pipe. Also the bushing is provided with external ribs H which, preferably, are parallel but are arranged slightly diagonally with respect to the axis of the bushing and these ribs embed themselves into the material ofthe pipe around the punched hole to form a Very `secure anchor--` age for the bushing when it is inserted through the pipe wall. t t
The inner end of the plunger 3 is provided,with` a cavity l2 extending from the upper side of the plunger and terminating just above the lower side thereof for a purpose to `be hereinafter stated. t
Screwed into the upper end of the body l there.
is a coupling I3 jwhose lower end is provided with a powder chamber Ill. The upper end of this -chamber lli isreduced in diameter to receivela-1 primer cartridge l5.

The:v latch 46 slides in a ver'- tical groove 5 Iv cuttirr the external surfaceof the barrel 21'Yand in substantialvalignment withv thel groove" 39.. The` latch 46` hasi an upward extension 46a. which is provided? with a-vertical slot-5 I;
Pivotally mounted in the slot` 5I4r andlon tl'iei body 21 there is arv trigger-52; This trigger "isi-of. asemi-circularv shapewith itsstraigh-t edgefnorf'V mally held in `af ilush relation Withthe'surfa'ce of" thebarrel 21"l: y-4 means of av tensioni spring 53,. one` endi ofwhich is attached tothe. stationary' axisf pin 54fon which the trigger worksand'whose' other:` end i's-atta'ched'to the trigger. The curvedl margin of the trigger 52v works in tl'ieslot 5I', as" shown in Figures 5 and 7.
When it isdesired to run the` tool into the pipe inr a well the latch 48 will be interengagied'with.A theupper end of the supporting arm40, Ias ist indicated iin Figure 2, and' will'be maintained iIL thaty position `by the shear pinl 50.' and" justbeforethe' triggerl enters the upper end of the pipes.` it will befswun'g around in a clockwise. direction. as indicated inrFigure 2", so that itszouter endlwilll rideagainst the inner surfaceof the pipe.y
As the tool' is lowered'` the. trigger. 52jvrililpass;`
the pipe couplings freely without engaging therel in and the lower end of thesupportinggarm 40 will be held retracted' into the groove38, asf shownin Figure 2. When. ay pointzh-as-.beenr reached where it is, desired` tov operatetheftool the tool: may be. pulled upwardly and. the outer' end ofelthe` trigger` 52r will engage-in .the` coupling aboveeand the outer. end of said trigger will be therebyl-ieldf and as vthe tool is moved further upwardly-fthe: innervl endxof ther trigger will engage the upper'. end of the slot 5I thus exerting'anv upward'pulli on thee-ranch, shearingr the pin so and releasing. the latch from the upper endofi'thef supporting'1 arm 40 and'thereuponthejspring 4I willf'orce. y

The jars may then be operated. Any type of jars may be employed. As shown the jars include a hammer 55 to whose upper end the cable 26 is secured and upon suitable manipulation of the cable the hammer 55 may be dropped against the upper end of the firing pin 29 thus causing the point 22 of said pin to perforate the disc 2l and fire the primer cartridge I which ignites the main charge I4. The explosion will rupture the disc I5 and a high pressure will be suddenly created in the expansion chamber I1 which will suddenly drive the plunger 3 outwardly forcing the bushing 1 through the well pipe 56, as is indicated in Figure 6. As hereinbefore indicated,
Y the forward end of the bushing is so formed that the bushingr will readily penetrate the pipe and the external ribs on the bushing will embed themselves into the material of the pipe around the punched hole so as to maintain the bushing in` the pipe.
The bushing may be detachably secured to the plunger 3 in any preferred manner. As illustrated in Figure 4 it is gripped by the gripping fingers 51 on the forward end of the plunger 3 which will release the bushing when the bushing is punched into the pipe.
The gland I9 is provided with a plurality of radial exhaust ducts 58 to permit an exhaust of a portion of the pressure from the explosion and upon forward movement of the plunger 3 the exhaust passageway 34 will be partially cleared by the plunger and will rupture the disc 33 thus forcing the plunger 30 downwardly, shearing the pin 35 and the head 3| will finally land on the shoulder 31 clearing the exhaust openings 36 to allow a free exhaust.
After the insertion of the bushing the tool may then be elevated and the trigger 42 will assume its normal position, as shown in Figure 7, and the lower end of the slot 38 will engage the lower end of the narrow key 42 operating to retract the supporting arm 40 into the slot 39, as shown in Figure 7, and the tool may then be readily withdrawn from the well pipe.
Should the inserting tool become stuck in the well an upward pull may be exerted on the cable 26 suilicient to shear the pins 24 and remove the cap 23 which may be drawn to the ground surface and any conventional type of grapple,
of sufficient strength for the purpose, may then be lowered into the well pipe and engaged over the external annular flange 59, provided for the purpose on the upper end of the gland I9 and the inserting tool may then be withdrawn from the Well.
The drawings and description are illustrative merely while the broad principle of the invention will be dened by the appended claims.
