    Abstract: A stapler device and a method of stapling an article. The stapler has a striker and a spring for driving the striker to apply a staple. During the stapling cycle, the striker and spring are cocked and loaded prior to being release to apply the staple. While the stapler is in the cocked and loaded position the stapling cycle is automatically interrupted to maintain the spring and the striker in the cocked and loaded position. The stapler device may be then moved to a second location before the interruption is discontinued by an actuator. Once the stapling cycle is continued, the cocked and loaded striker and spring are released to apply a staple. The device is also selectively capable of a second mode of operation wherein the stapling cycle is not interrupted.

A magazine assembly feeds fastener elements individually in succession into the column to be forced down into the ground when the driver is moved down by pushing the foot pedal down. The magazine assembly has a magazine housing located on the opposite side of the column from the foot pedal, a magazine removably received in the magazine housing and slidably supporting a continuous series of the fastener elements, and a spring-biased follower which urges the fastener elements toward the column.

  • Patent number: 4699307
    Abstract: A machine for driving glazier's and framer's points utilizes a push plate which is effective to drive the points at both of two levels. A ramp element is incorporated, which serves to deflect the points from an upper to a lower level as they are being driven forwardly into the workpiece, and edge features of the points employed impart a rotation or turning action thereto which deflects the tail portions downwardly to bear tightly upon the glass plate or other piece that is being mounted. Features of the points cooperate with elements of the magazine to ensure proper orientation, and the machine is effective and comfortable to use.

  • Patent number: 4624401
    Abstract: A device for driving fastening elements, such as nails, staples and the like, includes a magazine extending transversely from a driving unit. A follower is located within the magazine for supplying fastening elements to the driving unit. For filling the magazine with fastening elements, the follower can be secured in a loading position. The follower is secured by a stop pivotally attached to the follower which engages an abutment on the magazine. The follower is released from the loading position by an actuating member movably mounted on the magazine so that it can contact an engagement part on the follower and pivot the stop out of engagement with the abutment.

  • Patent number: 4558811
    Abstract: The invention is concerned with a nail driving tool preferably operable in pneumatical manner, comprising a magazine for nails composed to form straight rows or straight strips, which nails are successively forced from the front end of a guide, possibly corresponding to the staggered arrangement of the nails, and obliquely terminating into a drive-out channel via a lateral inlet channel into a presenting composition for being, e.g., pneumatically forced out of the drive-out channel. For increasing the magazine capacity while maintaining a handy volume, it is provided that the magazine be formed as a box-type magazine of a width suitable for accommodating two or more nail strips or rows in side-by-side relationship and that the nail strips or rows can be successively forced in a direction normal to the planes of the nail strips or rows into alignment with the inlet channel of the drive-out channel.

  • Patent number: 4524896
    Abstract: A reversible feeder shoe and door system for the magazine of a staple driving tool enabling set-up of the tool for right or left handed loading. The tool magazine comprises an elongated rail terminating at its forward end at the guide body of the tool. A row of staples is slidably mounted in straddling fashion on the rail. A feeder shoe, having a substantially symmetrical inverted U-shaped body, is slidably mounted on the rail in straddling fashion behind the row of staples. A resilient member constantly urges the feeder shoe forwardly so that the forwardmost staple of the row is located in the guide body drive track. The magazine may include a U-shaped elongated body in which the track is mounted. An elongated door is provided, swingable between an open position exposing the rail top and a closed position overlying the rail top to prevent inadvertent dislodgement of the staples from the rail.

  • Patent number: 4470531
    Abstract: An improved nailing machine including a reciprocatable plunger for sequentially severing and driving nails from a nailing strip, and a reciprocatable piston for advancing and retracting the plunger. The machine includes a unique reciprocatable control valve actuating and nail guide means which serves both to set a control trigger for activating the reciprocatable plunger, and to properly align a nail with a workpiece as the nail is driven into the workpiece, while at the same time maintaining the nailing strip in a fixed position to prevent contact between the driven nail and the next nail to be severed from the nailing strip. The machine further includes a magazine having retractable nailing strip advancing means which positively moves a nailing strip along the runway of the magazine, and which, in its retracted position, enables a nailing strip to be easily and readily inserted into or removed from the magazine of the machine.

  • Patent number: 4463888
    Abstract: A tool for driving uncollated nails includes a tool body with a nose portion defining a drive track wherein a driver blade moves in drive and return strokes. A magazine carried by the body supports a row of nails, and a pusher urges the nails along a feed path toward the drive track. The magazine is adjustable for tailoring the feed path width to the nail size. Individual nails are advanced from the magazine to a drive position in the drive track by an escapement mechanism operated in timed relationship with the driver blade, and an advanced nail is held in the drive position by a magnet assembly supported by the tool nose portion. Nails are positively advanced and are properly oriented by the escapement mechanism independently of the number of nails, the pusher force, or other conditions in the magazine. The tool magazine is quickly and conveniently loaded with nails supplied in an oriented condition from a loading chute.

  • Patent number: 4432484
    Abstract: An improved tool for driving metal fasteners, such as nails, brads, tacks, staples and the like in a frame and setting its rear closing panel. The tool comprises a driving lever suitable to urge, against a loading spring, a driving hammer which slides in the hollow bed of the tool. When the driving lever and the driving hammer disengage each other, the compression spring urges the driving hammer towards the outlet opening of the metal fastener, the latter being fed from a feeding magazine essentially perpendicular to the direction towards which the hammer is moved said magazine being provided with a pusher member for the metal fasteners.

  • Patent number: 4323184
    Abstract: Nails, screws and the like, referred to as fasteners, are automatically supplied into the magazine of a driver for the fasteners from a supply chute. A slide pusher may extend out of the free end of the magazine and cooperates with a gate at the discharge end of the supply chute, whereby the gate is opened when the free end of the magazine is inserted into the discharge end of the supply chute. In this position the magazine slide pusher is located in a recess to permit the fasteners to freely pass by the slide pusher into the magazine guide channel. When the magazine is full it is withdrawn from the supply chute, whereby a spring closes the gate and the slide pusher is moved back into the magazine guide channel to push the fasteners toward the magazine discharge end under the force of a spring in the magazine.

  • Patent number: 4200216
    Abstract: In the housing of a setting device for driving fastening elements, a belt-like magazine holding fastening elements in spaced relation is moved through a guide channel transversely of the path of a driving piston. A transport device positioned in the housing moves the magazine through the guide channel in a step-wise manner. A stop lever is pivotally mounted in the housing and is spring-biased at one end into the guide channel. When the magazine is located within the guide channel in the path of the stop lever, the transport device can be operated to move the magazine. When the magazine is moved out of the path of the stop lever, however, the stop lever extends further through the guide channel and its other end engages a pawl on the transport device blocking its operation so that the magazine cannot be moved through the guide channel.
