Abstract: A projectile launcher has first and second telescopingly connected sections enabling it to be extended into an operative state when it is to be discharged. The firing mechanism has a firing member carried by the first section which extends into a housing on the second section. The rear of the housing is a chamber for a pivoted trigger having a forward portion of greater length than its rearward portion and underlying a boot covered port. A rotary sear in the chamber has first and second arcuately spaced shoulders the second of which is engaged and held by the rearward trigger portion under the influence of a spring. When but a short further relative movement between the sections is required to fully extend the launcher, the first sear shoulder engages and pulls forward the firing member thus to cock the firing mechanism when the launcher is fully extended, the firing spring then exerting a substantial force against the first shoulder.

Abstract: A trash compactor has trash compacting means attached to a chassis that is supported in the upper end of the housing for limited movement relative to its side walls and is detachable in a manner facilitating servicing of the trash compacting means. The chassis moves upwardly in response to reaction force developing on the application of compacting pressures to the trash by the compacting means and, at its upper limit of travel, it transfers the reaction forces to the side walls of the housing.
