  • Patent number: 10967492
    Abstract: A staple gun and a method of using the same. A stapling mechanism in the housing is activated to deliver a staple through an aperture in a housing wall and drive the staple into a surface around a stack of one or more electric cables. The gun includes a reciprocating cable guide for centering the gun on the stack of cables and closing a safety switch to permit the gun's trigger to be activated. A spacer extending outwardly from the housing wall rests on the upper surface of the cable stack. The spacer and a bumper that engages a hammer of the stapling mechanism provide for automatic depth adjustment when driving the staple into the surface. A reciprocating cable guard extending outwardly from the housing wall is positioned between the stack of cables and the staple to aid in preventing the staple from piercing the cable.

The feed member includes a feed tooth which feeds the fastener to the injecting passage by engaging with a rear portion of the fastener and an auxiliary tooth which is disposed on a foot side of the fastener to prevent the fastener from deviating from the injection passage. When the feed tooth of the feed member projects into the supply passage, the auxiliary tooth projects into the supply passage longer than the feed tooth.

  • Patent number: 9662777
    Abstract: The invention provides, in one aspect, a pneumatic fastener driver including a cylinder and a piston positioned within the cylinder. The piston is moveable between a top-dead-center position and a bottom-dead-center position. The driver also includes a magnetic latch emitting a magnetic field that magnetically attracts the piston and is capable of holding the piston in the top-dead-center position with a magnetic force. The magnetic latch is adjustable to vary the magnetic force acting on the piston for driving fasteners into a workpiece at different depths.

  • Patent number: 9615566
    Abstract: An animal trap may include a source of compressed gas; a trigger mechanism configured to be actuated by an animal, and a kill mechanism powered by compressed gas. The trap may include two or more trigger valves connected in series. At least one trigger valve may include an opening, a valve seat surrounding the opening, a valve member having a sealing surface, and an O-ring arranged to seal between the sealing surface and the valve seat. One or more flow paths may allow gas to flow along at least part of an internal periphery of the O-ring. The trigger may include a trigger rod extending in a rest position from a mount at or near a first end thereof. The trigger rod may be mounted for pivoting movement about the mount, and may have two rotational degrees of freedom. Pivoting movement of the trigger rod in any direction away from the rest position may result in actuation of the trigger.

  • Patent number: 9611895
    Abstract: An alignment device aligns rollers R in an annular shaped alignment space 24 in parallel to each other while at the same time prevents damage from occurring on rolling surfaces of rollers R. Plural rollers R that are arranged in a row in an axial direction are sequentially supplied into an annular shaped alignment space 24 that is formed in a main jig 14 in a direction that coincides with a width direction of the alignment space 24. The plural rollers R are aligned in an annular shape so as to be in parallel to each other by alignment-fluid-supply means 16 spraying air onto a roller R that is in a supply position in the alignment space 24 from a direction that is orthogonal to the roller R supply direction and moving the roller R in a circumferential direction of the alignment space 24, and then supplying a next roller R into the alignment space 24.

  • Patent number: 9555529
    Abstract: A device for applying fasteners having one almost flat head having a central pass through hole, two opposed sides having protrusions approximately perpendicular to the head forming shoulders, has a first nail magazine for locking a fastener. A shooting device shoots a nail through the fastener central hole. A second magazine has a slide guide housing a set of fasteners, with tongues oriented in a forward sliding direction, the shoulders oriented towards an outlet. The outlet has jaws hinged to rotation pins, perpendicular to the sliding direction. Front portions of the jaws fully protrude from the second magazine, each jaw having teeth having a shoulder shape to match a shoulder shape of a fastener interposed between the jaws. The teeth elastically and detachably hold the fasteners in an aligned position with the pass through hole and with the shooting direction of the shooting device.
