专利汇可以提供Cutting mechanism专利检索，专利查询，专利分析的服务。并且A parachute arrangement for pin point soft landing air cargo that includes a hand settable time delay cutting mechanism for cutting the reefing line of a cargo attached parachute after a predetermined drag force has been exerted upon a release pin cable. The mechanism includes a ballistic cutting blade carrying a powder charge in alignment with a timer controlled firing pin. A release pin actuates the timer when the cable drag force removes the release pin from its normal position extending in the path of a timer lock member.，下面是Cutting mechanism专利的具体信息内容。

权利要求

1. In a parachute arrangement for pin point soft landing air cargo having a continuously settable mechanical time delay cutting mechanism, and a cargo attached parachute with a reefing line thereof secured transversely through a cutting chamber of said mechanism and positioned forwardly of a cutting blade slidably mounted in said chamber, said mechanism including a timer controlled firing pin for igniting a powder charge in a rearward portion of said chamber and a spring loaded timer lock member, a release pin normally extending in the path of said timer lock member, and a parachute cable secured to said release pin and capable of being subjected to a predetermined drag force prior to releasing said pin from its normally extending position.

2. The structure in accordance with claim 1 wherein said delay cutting mechanism includes a timing fuze member, said firing pin and said spring loaded timer lock member being located within said fuze member, said fuze member having a protruding bottom portion that has a pair of threaded openings, a first cylinder defining said cutting chamber secured in one of said openings in alignment with said firing pin, a second cylinder secured in the other of said openings and slidably receiving said release pin.

3. The structure of claim 2 wherein said first and second cylinders extend substantially parallel to each other, and a plate having a pair of apertures interconnects said first and second cylinders.

4. The structure of claim 2 in which a shear pin is carried by said release pin and extends laterally therefrom in the path of said second cylinder.

5. The structure of claim 1 wherein said cutting blade is defined by a cylindrical body having an annular recess in the forward face thereof.

6. A continuously settable mechanical time delay cutting mechanism for pin point soft landing air cargo comprising a fuze containing a timer controlled firing pin and a spring loaded timer lock member, a release pin normally extending in the path of said timer lock member, a cable secured to said release pin and capable of being subjected to a predetermined drag force prior to releasing said pin from its normally extending position, a cutting chamber secured to said fuze and adapted to house a transversely extending parachute reefing line, a cutting blade slidably mounted in said chamber and having a powder charge in its rearward end in alignment with said firing pin, so constructed and arranged that said cutting blade can be operated upon said cablE being subjected to a sufficient drag force.

7. The structure of claim 6 wherein an elongated tubular body is secured to said fuze and houses substantial portions of said release pin and cable, and an apertured plate interconnects said chamber and tubular body.
