An example simulated weapon includes a delayed trigger and a pellet ejector. The delayed trigger includes a chamber and a piston slidable between armed and triggering positions. A spring biases the piston towards the triggering position. A locking member releasably locks the piston in the armed position. Release of the piston by the locking member causes the spring to move the piston from the armed position to the triggering position. The pellet ejector is coupled to the delay trigger to be triggered by the delay trigger in the triggering position. The pellet ejector includes a pressure chamber to receive a pressurized fluid and a pellet chamber to receive pellets. A valve is disposed between the pressure chamber and the pellet chamber communicates pressure from the pressure chamber to the pellet chamber. A barrel that extends through the pressure chamber is connected to the pellet chamber to eject the pellets.

Delayed trigger, pellet ejector, and simulated weapon

A reusable simulated weapon device includes a holding chamber and an expansion chamber for receiving expanding gas. A shuttle is slidable between a closed position that blocks communication between the holding chamber and the expansion chamber and an open position that allows communication. A pilot valve allows pressurized gas in the holding chamber to drive the shuttle into the open position. A firing pin opens the pilot valve. The firing pin has an armed position, in which a protrusion engages with a recess to hold the firing pin against a spring. The firing pin can be released from the armed position in response to an impact to the device. When the firing pin is released, the spring drives the firing pin to actuate the pilot valve, causing the shuttle to slide from the closed position to the open position to allow gas to move into the expansion chamber.

Reusable simulated weapon and triggering mechanism

A saw blade for an oscillating saw can include a plate having cutting teeth arranged in an arcuate tooth pattern at a cutting path. Cutting teeth on opposite sides of the centerline of the plate may be arranged to face oppositely. Each cutting tooth can have primary and secondary relief surfaces at different angles to the cutting path. Cutting teeth may be offset outwardly from the plate, with tips of some of the cutting teeth having outward-facing kerf surfaces parallel to the plate. The plate may be of bimetal construction, so that the cutting teeth and bulk of the plate are made of different materials. The cutting teeth may be formed by a coining process.
