ABSTRACT OF THE DISCLOSURE A time delay device for, in use, combination with a firing device demolition of the type having a pivotable member adapted to release a firing pin to detonate an associated explosive element. The time delay device comprises a pivotable member adapted to release a piston arrangement one and of which arrangement being exposed to fluid within a chamber. A control piston is also provided having one end exposed to fluid in the chamber via a supply port, and a valve is provided to set the rate of transfer of fluid through the supply port under the influence of the pressure exerted by the release of the piston arrangement. In use, the control piston cooperates with the pivotable member of the firing device demolition to hold the pivotable member in a deactivated condition and is subsequently movable to a position under the influence of the fluid pressure, at a rate depending on the setting of the valve, whereby the pivotable member of the firing device demolition will be released and moved to a firing pin release position whereby the firing pin will be released to detonate any associated explosive element. - 1 -
