Definitions
- This invention relates to cartridge powered stud drivers and in particular to an extractor for such tools.
- a great many cartridge powered tools are made with chamber bushings which hold the cartridge during firing and which must be removed so that the fired shell can be removed. Some of these tools have studs positioned in hollow handles so the operator can force the shell out of the bushing. The tool is normally loaded by placing the bushing in the barrel and then putting an unfired cartridge in the bushing.
- This invention relates to the addition of an extractor to a tool currently in production which requires a minimum amount of revision to the tool to install.
- a further purpose of this invention is to provide an extractor for a cartridge powered tool originally having a chamber bushing.
- FIGURE 1 is a side elevation view partially in section of a cartridge powered tool incorporating the present invention
- FIGURE 2 is a side elevation view of the barrel assembly of a cartridge powered tool incorporating the present invention
- FIGURE 3 is a side elevation view of the barrel assembly of a cartridge powered tool incorporating the "ice present invention and showing the guide tube in the readyto-fire position;
- FIGURE 4 is a side elevation view of the barrel assembly of a cartridge powered tool incorporating the present invention and showing the extractor fully actuated;
- FIGURE 5 is a' side elevation view of the tool showing the tool in the open position
- FIGURE 6 is a longitudinal sectional view taken through FIGURE 2 showing the details of the instant invention.
- the powder actuated tool shown incorporating the instant invention has a cover 1 and a housing 2. These two portions or sections are locked together by means of a latch 3 which is slidably mounted on housing 2. Cover 1 and housing 2 are pivotally hinged together by means of a bolt 4.
- Housing 2 contains a fire control mechanism which does not constitute any part of the present invention and is not shown.
- a breech member or breech cover 5 closes the end of housing 2. Cover 5 is arranged to close over the end of barrel 6 when cover 1 and housing 2 are in the closed position.
- a slot 7 is formed in cover 1 to receive latch 3.
- a button 8 is mounted in the underside of housing 2 which can be depressed and its extension will then lift latch 3 out of slot 7 so that housing 2 and cover 1 can be swung open.
- a barrel assembly 9 which includes barrel 6. Set screws (not shown) thread into cover 1 and retain barrel assembly 9 in cover 1. Assembly 9 also includes an action tube 10, an action bar 11, a washer 12, action spring 13, collar 14 and piston 15. Barrel 6 is formed with a chamber 16 to receive a cartridge and an extractor 17 is positioned in an opening 18 in barrel 6 adjacent chamber 16.
- FIGS. 2, 3 and 4 wherein barrel assembly 9 is shown with extractor 17 and action or guide tube 10 in their various positions before, during and after firing the tool.
- the action of spring 13 forces collar 14 toward the muzzle end of barrel 6.
- Spring 13 is retained between washer 12 and collar 14 and exerts its force on collar 14 due to the fact that washer 13 is positioned against a shoulder 19 formed on barrel 6.
- Action bar 11 is secured to collar 14 by welding or any other suitable means and is thereby moved by collar 14.
- Action tube 10 is formed with a groove 20 into which extends the end of set screw 21 so that while tube 10 is retained in cover 1 it is free to move rearward in tube 10.
- the end of tube 10 near the breech abuts collar 14 so that pressing of the muzzle end of tube 10 compresses spring 13 as collar 14 moves rearward.
- a screw 22 is positioned in action bar 11 and extends through bar 11 into a slot 23 in extractor 17.
- tube 10 is slidably mounted over barrel 6 and is part of barrel assembly 9 which includes those elements previously set forth as well as a barrel extension 24, coupling 25 and a buffer 26. Tube 10 slides over the barrel assembly from the muzzle end and abuts collar 14. It can be seen that barrel extension 24 and coupling 25 are enclosed completely by tube 10. Buffer 26 is included to protect the tool if a no work short is made, that is, the
- Extension 24 has a smaller diameter than barrel 6 so as to retain piston 15 in the tool. It can be seen therefore that movernent of action bar 11 causes movement of extractor 17.
- FIG. 2 wherein barrel assembly 9 is shown in the normal position.
- tube 10 is biased forward by the action of spring 13 and collar 14. This action also biases bar 11 forward so that extractor 17 is within opening 18 in barrel 6 and forms a portion or segment of chamber 16.
- the muzzle end of tube 10 is pressed against a work surface compressing spring 13 by causing collar 14 to move rearward. Movement of collar 14 causes bar 11 to move rearward and cock the firing pin contained in the fire control positioned in housing 2. Screw 22 carried by bar 11 moves rearward in slot 23 in extractor 17 but is restrained from moving extractor 17 rearward due to extractor 17 being held in position by breech member 5. This ready-to-fire position of barrel assembly 9 is shown in FIG. 3.
- the tool breech cover is formed with an opening as shown in FIGURE 5 to receive the end of barrel 6 in a sliding engagement.
- button 8 When button 8 is pressed, this action lifts latch 3 out of slot 7 formed in cover 1 allowing the operator to rotate cover 1 and housing 2 away from one another about bolt 4.
- This rotating action slides the breech end of barrel 6 containing chamber 16 out of engagement with the opening formed in breech cover 5.
- This opening as can be seen in FIGURE 5, is formed to receive the breech end of barrel 6 when the tool is closed but to allow the barrel 6 to freely slide out of the opening when the tool is opened by the operator.
- barrel assembly 9 is shown in the cartridge extraction position.
- button 8 is depressed lifting latch 3 out of slot 7 and cover 1 and housing 2 are swung apart exposing the breech end of barrel 6.
- the operator grasps tube and moves it rapidly to the rear.
- extractor 17 is free to move rearward and is so moved as scew 22 engages the end of slot 23 causing extactor 17 to move rearward of 4 barrel 6. This movement removes the fired case of a cartridge contained in chamber 16.
- An extractor system 'for a powder actuated tool comprising an extractor attached to the barrel of said tool adjacent said breech end, said extractor positioned to engage the head of a cartridge positioned in the chamber formed in the breech end of said barrel, an action bar movably mounted outside said barrel and biased toward the muzzle end of said barrel, a member mounted on said action bar to engage said extractor and an action tube surrounding said barrel adjacent said muzzle end in engagement with said action bar whereby movement of said action tube toward said breech end of said barrel causes said action bar to move and carry said extractor past the breech end of said barrel to remove a cartridge positioned in said chamber.
