Definitions
- Cited cartridges are fed from a magazine into breech- UNITED STATES PATENTS loading position in response to relative movement of a barrel to breech-open position.
- Anchoring elements such as studs, pins and other elongated fasteners are commonly driven into metal, concrete or other hard materials by means of handheld, explosively fired tools.
- each cartridge to be ignited may be individually placed with one hand into firing position of a tool gripped by the other hand of an operator, there are numerous occasions where more rapid and automatic cartridge loading can insure increased output with greater convenience.
- Weather or other conditions may require gloves to be worn, and an operator cannot manipulate and load small cartridges (often of only .22 calibre) one at a time in conventional tools without removing at least one glove every time the tool is to be fired.
- small cartridges often of only .22 calibre
- a gun of this general type is disclosed, for example, in US. Letters Pat. No. 3,168,744 issued Feb. 9, 1965. While such guns may be characterized as a ram or piston type operable at relatively low velocity for low to medium duty fastening, the present invention is applicable as well to the so called free flight or ram-less type of tool operable at higher velocity for medium to heavy duty fastening.
- the invention contemplates provision of a raceway externally mountable on a gun body and adapted to receive a row of cartridges, means on the raceway for urging endmost cartridges therein into juxtaposition to a closable breech, and a cartridge carrier automatically shiftable to carry successive endmost cartridges from the raceway into the breech for alignment with a barrel bore when the barrel moves relative to the body and away from the firing position, the carrier being operable by mechanism energized by cocking movement of the barrel.
- a further feature of the invention resides in the provision of a cartridge feeder attachment comprising a magazine portion and a cartridge transferring mechanism substantially in alignment therewith, the mechanism comprising a floating cartridge carrier for receiving successive endmost cartridges from the magazine portion, a member energizable by relative cocking movement of a gun body and its barrel, and means disposed between the member and the carrier to control movement of the latter between an external cartridge loading position and an internal ibreech delivery position.
- the magazine portion includes an escapement mechanism for retaining each endmost cartridge, and the member when energized is effective to cause the cartridge carrier to operate the escapement mechanism whereby the carrier is reloaded.
- FIG. 3 is a section taken on the line IlIlIl of FIG.
- FIG. 4 is a view taken on the line IV lV of FIG. 1;
- FIG. 5 is a view of the cartridge loading mechanism shown in FIG. 1, but now inverted and the breech being partly open;
- FIG. 6 is a longitudinal section of the cartridge loading mechanism of FIG. 5 when turned about its axis, the part now occupying breech fully-open positions;
- FIG. 7 is a view similar to aportion of FIG. 6 with the breech partly open as in FIG. 5 and the feed mechanism locked in single-shot position, and
- FIGS. 8-l3 are sectional views of portions of the cartridge feeding mechanism in a cycle of operations commencing with a breech-closed condition shown in FIG. 8.
- an explosive tool generally designated 14 has a main body 16 which is hollow for largely enclosing firing mechanism including a trigger 18.
- the body supports a hand grip 20 by which the tool may be wielded.
- a tubular forward portion 22 of the body 16 is open on one side as at 24 forproviding cartridge loading access to, and ejection from an axially bored breech end 26 (FIGS. 6, 7 and 10)of a barrel 28 when the latter has relatively moved forwardly as indicated in FIGS. 5, 6, 7, 9, and 10.
- the tool 14 preferably is a commonly known type wherein a muzzle end 30 is thrust endwise against a surface S (FIG. 1), after stud and cartridge loading to relatively retract the barrel 28,
- the gun 14 may receive a manually loaded single cartridge C in its breech bore, and the gun is further provided as will next be explained with an automatic cartridge feeder attachment generally designated 32 (FIGS. 1, -10) for optionally facilitating repeat-fire operation and hence repeated installation of drive pins or the like (not shown) successively receivable in and to be driven from the muzzle end 30.
- the attachment 32 is elongated and comprises a magazine end portion 34, a base portion 36 to be disposed lengthwise of the gun 14, and feeder mechanism generally designated 38 (FIGS. 513) mounted on 'the portion 36'.
- a clamping collar 40 for detachably securing the attachment assembly 32 a clamping collar 40 (FIGS.
- the magazine end portion 34 of the attachment 32 includes a cartridge raceway or slide 46 (FIGS. 2, 5, and 6) longitudinally slotted and undercut to slidably receive a row of cartridges C which are thus retained by their rims.
- the cartridges may be simultaneously loaded into the slide 46 from a disposable tear-off plastic supply strip (not shown) perforated to carry them in suitably spaced alignment.
- a pusher block 48 (FIGS. 2, 5, and 6) longitudinally slotted and undercut to slidably receive a row of cartridges C which are thus retained by their rims.
- the cartridges may be simultaneously loaded into the slide 46 from a disposable tear-off plastic supply strip (not shown) perforated to carry them in suitably spaced alignment.
- a right-hand endmost cartridge C is urged toward the breech and against spaced retainer pins 60,60 (FIGS. 2 and 5) formed of a U-shaped wire carried by the free end of an escapement leaf spring 62 (FIGS. 1, 2, 6 and 8).
- This spring is affixed at one end I to the base portion 36 by-screws 64,64. It will accordingly be understood that successive endmost cartridges C are positioned, upon release by the pins 60, to be transferred into the jaws of a spring clip 66 (FIGS. 5-7 inclusive) preparatory to breech-loading by the feeder mechanism 38 as will next be described.
- the clip 66 is affixed by a screw 68 to a floating cartridge carrier 70 (FIGS. 1, 5-13) which is operable by the feeder mechanism 38 to transfer successive cartridges from the external receiving breech-closed position, shown in FIG. 8 to the internal, breech-loading position (FIGS. 6 and 11) and then retract for receiving another cartridge.
- the mechanism 38 is energized by cocking the gun as above described. This is to say that a push rod 72 (FIGS. 6, 8-10), mounted as will be described on a longitudinal, U- shaped track extension 75 of the base portion 36 yieldingly carries a block 74 having a projection radially engageable with the recoil ring 44, and the rod will be displaced rearwardly in the feeder attachment.
- a compression spring 76 nested in the block 74 urges the latter into engagement with the ring for a purpose later mentioned and the block is restrained by pins 78, 78 respectively arranged in parallel elongated slots 80, 80 (FIGS. 8 and 10), the pins being in the block 74 and the slots formed in the push rod 72.
- a spring 82 (FIGS. 5 and 8-10) confined between a tang 84 struck from the push rod 72 and a tang 86 struck from the track extension 75, becomes compressed as shown in FIG. 8.
- a pin 87 extends transversely therein through a longitudinally slotted guide 89 and abuts the tang 84 to restrain the spring 82.
- a cam end 88 of the push rod 72 therefore progressively engages a surface 90 of a lever 92 pivotally connected at 94 to the cartridge carrier 70 as the barrel breech end 26 moves from its carrier camming position shown in FIG. 1 1 to those shown sequentially in FIGS. 12 and 13. Consequently, and with the aid of the now compressed spring 76, the lever 92 which is pivotally mounted on a cross pin 96 in the attachment 32 is caused to assume a position parallel to the base portion 36 as'shown in FIG. 8.
- a tension spring 98 interconnects the pin 96 and a pin 100 in the carrier, and another tension spring 102 interconnects a cross pin 104 fixed in the base 36 and a pin 106 in the lever 92.
- the lever 92 has a transverse slot for avoiding interference with the pin 104 as the lever assumes the position in the feeder attachment generally parallel to'the axis of the retracted barrel and to the push rod 72.
- the carrier 70 is at once pivoted clockwise by the influence of the spring 98.
- the spring 102 effects added clockwise movement of the carrier 70 to shift the cartridge with the clip 66 to the position approaching parallelism with the barrel bore.
- a pin 110 in the carrier 70 rides into alignment grooves 1 12 formed in the base portion 36 thus guiding and stabilizing the carrier preparatory to shifting the control cartridge to the barrel breech-closing position as shown in FIGS. 11-13.
- confronting flat surfaces of the carrier 70 and the lever 92 comelnto abutment or stop engaging positions.
- the breech end 26 successively engages a cam portion 114 of the carrier 70 and the clip screw 68 to effect substantially right angle withdrawal of the clip 66 from the axis of the delivered cartridge. That the rim of this cartridge is not fully seated is of no effect on its subsequent ignition.
- the cocking of the gun to ready it for firing of the delivered cartridge is accomplished by the return of the push rod to restore the feeder mechanism to its energized and reloaded position shown in FIG. 8, a recess 116 (FIGS. 6 and 7) in the carrier 70 allowing for alignment of the carrier with the track extension 75.
- a push button stop 118 (FIGS. 1, 3, 4 and 6-10) is provided. Referring to FIG. 4 the stop 118 is axially slidable in a bore formed in the clamping collar 40 to different positions releasably determined by engagement of a springpressed detent 120 in the collar with one of a series of mating notches 122 formed in the side of the stop 118. A flat 124 on the stop 1 18 is disposed to accommodate passage therethrough of the push rod 72 when automatic cartridge feeding is desired, as shown in full lines in FIG. 4.
- the stop 118 is shifted to its dash-line position (and corresponding to that indicated in FIG. 7) where the breech is only partly open.
- the wall of a cut-out 126 (FIG. 6, 9, and 10) in the push rod 72 then engages the stop 118 to lock the rod 72 and hence the feeding mechanism against operation.
- the barrel 28 can of course still be retracted to cocked condition and the tool otherwise employed in usual manner.
- the feeder attachment 30 provides uncomplicated mechanism which is conveniently operable for converting a single shot tool to optional, reliable repeat fire operation.
- a cartridge feeder attachment for an explosive fastener driving tool of the type having a barrel provided with a breech formed with a bore and movable between breech-open and breech-closed positions relative to a body to cock the tool, the attachment comprising a magazine portion extending externally of the body for presenting successive cartridges to a position adjacent to the breech, and feeder mechanism including a cartridge carrier responsive to cocking movement of the barrel to cause the successively presented cartridges from said magazine portion to be loaded onto the carrier and the carrier to be energized for presenting the loaded cartridge into alignment with the barrel breech bore when the breech is opened.
- a cartridge feeder attachment comprising an elongated base portion adapted to be secured to a body of an explosive fastener driving tool, a magazine portion extending generally parallel to the axis of a tubular portion of the body adapted slidably to receive a barrel having a breech bore, said magazine portion including an escapement, and loading mechanism mounted on the base portion substantially in alignment with the magazine portion for receiving sucessive cartridges therefrom to be presented in coaxial alignment with the barrel breech bore, said mechanism including a movable cartridge carrier cooperative with the magazine portion to receive successive cartridges therefrom, a member energizable by relative movement of the barrel to a breech-closed position, and! carrier controlling means including a lever pivotally connected to the base portion and to the carrier, said lever being en'gageable by the member when energized to cause return movement of the carrier from its cartridge delivery position to operate said escapement and reload the carrier.
- a barrel operated cartridge feeder assembly for external attachment to a body of an explosive fastener driving tool having an axially movable barrel, said assembly comprising a cartridge magazine including an escapement for releasing successive cartridges to be loaded into a position coaxial with a closable breech bore of the barrel, a base adapted 'to be secured to the body for supporting the magazine with its escapement adjacent to the closable barrel breech, and mechanism mounted on the base for operating the escapement and transferring cartridges therefrom to said loading position, said mechanism including a lever pivoted to the base, a cartridge carrier pivoted to the lever, spring means connecting the lever to the base and to the carrier for influencing pivotal relation of the latter relative to the body, and means energized by breech closing movement of the barrel relative to the body to overcome the spring means and cause the cartridge to operate the escapement.
- an explosive driving tool of the type having a body having an opening providing access for breech loading of successive cartridges, a barrel slidable in the body between breech-open and breech-closed positions, and a magazine means for presenting successive cartridges to a position adjacent to and externally of said body opening
- a cartridge loading mechanism responsive to relative axial movement of the barrel and body, said mechanism including a cartridge carrier operable to receive successive cartridges from the presenting position of the magazine means, a member for yieldingly supporting the carrier for movement into and out of the body opening and for pivotal movement about an axis normal to the axis of the barrel, the arrangement being such that breech closing movement of the barrel cams the carrier radially from its cartridge delivery position, and an element energizable by the barrel movement is thereupon effective to cam the member to cause the carrier to be returned to cartridge receiving position adjacent to the magazine means.
- the magazine means includes a spring-actuated escapement for normally retaining cartridges in the magazine means, and the carrier is fitted with a clip having jaws yieldable to peripherally embrace each cartridge adjacent to its rim, the escapement being operable to release a cartridge to the jaws of the clip in response to pivotal movement of the carrier by said element.
- a U-shaped base largely encloses the carrier, the member, and said element, and a pin disposed in the carrier is arranged to be received in a complemental groove in the base upon presenting a cartridge to a bore of the barrel whereby the carrier is stabilized during transfer therefrom of a cartridge to the barrel bore.
