Abstract

Stun grenade includes a steel housing having a steel tubular body with steel end members brazed to the ends of the tubular body, and a brass collar member threadably received in a threaded central opening in one of the end members for supporting an explosive charge in the housing. At the inner end of the collar member is a cylindrical portion to which a tubular container filled with the explosive charge is attached. The outer diameter of the tubular container is less than the minimum diameter of the threaded opening in the one end member to permit the tubular container to be inserted through the threaded opening while attached to the collar member. At the outer end of the collar member is a threaded recess for threaded receipt of a fuse member externally of the housing. A flash hole in the collar member directs a flash which is produced when the fuse member is activated into the tubular container to ignite the explosive charge.

Claims

1. A reloadable stun grenade comprising a metal housing including a metal tubular body having first and second metal end members secured to opposite ends of said body, a threaded opening in one of said end members, a collar member threadably engageable in said threaded opening, said collar member having a cylindrical inner end portion, a tubular container filled with an explosive charge attached to said cylindrical inner end portion, said tubular container having a diameter slightly less than the diameter of said threaded opening to permit said tubular container to be inserted through said threaded opening while attached to said collar member, a recess in an outer end portion of said collar member for threadably supporting a fuse member exteriorly of said housing when said collar member is threaded into said threaded opening in said one end member, flash hole means in said collar member for directing a flash which is produced when said fuse member is activated into said tubular container to ignite said explosive charge, and pressure relief hole means in said end members for relieving the energy that is produced when said explosive charge is ignited out through the ends of said housing.

2. The stun grenade of claim 1 wherein said recess in said collar member is internally threaded for threaded engagement by a threaded end portion of said fuse member.

3. The stun grenade of claim 1 further comprising tape means on said collar member covering said flash hole means to prevent any of said explosive charge from entering said recess through said flash hole means.

4. The stun grenade of claim 1 wherein there are a plurality of circumferentially spaced pressure relief hole means in said one end member.

5. The stun grenade of claim 4 wherein each of said pressure relief hole means in said one end member has a minimum diameter of approximately 15/64 inch.

6. The stun grenade of claim 4 wherein there are six of said pressure relief hole means in said one end member.

7. The stun grenade of claim 4 wherein there is a single pressure relief hole means in said other end member which has an area substantially equal to the combined areas of all of said pressure relief hole means in said one end member.

8. The stun grenade of claim 7 wherein said single pressure relief hole means in said other end member has a diameter of approximately 3/4 inch, and each of said pressure relief hole means in said one end member has a diameter of approximately 15/64 inch.

9. The stun grenade of claim 1 wherein said tubular body is made of 1/8 inch drawn over mandrel welded steel tubing.

10. The stun grenade of claim 1 wherein said end members are made of 12L14 steel.

11. The stun grenade of claim 1 wherein said end members are brazed to the ends of said tubular body.

12. The stun grenade of claim 11 wherein each of said end members includes a cylindrical end portion closely slidably received in the ends of said tubular body, and a flange at the other end in abutting engagement with the ends of said tubular body.

13. The stun grenade of claim 12 wherein the outer diameter of each of said flanges is substantially flush with the outer diameter of said tubular body.

14. The stun grenade of claim 12 further comprising external groove means intermediate the ends of said cylindrical portions of said end members for receipt of copper brazing wire in said groove means prior to insertion of said end members in the ends of said tubular body and applying heat thereto to braze said end members to said tubular body.

15. The stun grenade of claim 14 wherein said end members are brazed to the ends of said tubular body substantially throughout the length of said cylindrical portions and the width of said flanges which are in abutting engagement with the ends of said tubular body.

16. The stun grenade of claim 1 wherein there are a plurality of relatively small pressure relief hole means in said one end member and a single larger pressure relief hole means in said other end member having an area substantially equal to the combined areas of all of said pressure relief hole means in said one end member.

17. The stun grenade of claim 16 wherein said pressure relief hole means in said other end member is in substantial coaxial alignment with said threaded opening in said one end member.

18. The stun grenade of claim 1 wherein said explosive charge comprises approximately 15 ounces of flash powder.

19. The stun grenade of claim 1 wherein said collar member has external threads axially outwardly of said cylindrical inner end portion which, threadably, engage said threaded opening in said one end member, and said tubular container is pushed up against the bottom of said external threads and adhesively secured to said cylindrical inner end portion.

20. The stun grenade of claim 1 wherein said collar member is made of brass.

21. A stun grenade comprising a housing including a tubular steel body having first and second steel end members brazed to opposite ends of said body, means for reloading said housing with an explosive charge through one of said end members and for supporting a fuse member externally of said housing for igniting said explosive charge upon activating said fuse member, each of said end members including a cylindrical portion closely slidably received in the ends of said tubular body, and a flange in abutting engagement with the ends of said tubular body, external groove means intermediate the ends of cylindrical portions for receipt of brazing wire prior to insertion of said end members into the ends of said tubular body and applying heat thereto to braze said end members to said tubular body, and pressure relief hole means in said end members for relieving the energy that is produced when said explosive charge is ignited out through the ends of said housing.

22. The stun grenade of claim 21 wherein said end members are brazed to the ends of said tubular body substantially throughout the length of said cylindrical portions and width of said flanges which are in abutting engagement with the ends of said tubular body.

23. The stun grenade of claim 21 wherein there are a plurality of said pressure relief hole means in said one end member and a single pressure relief hole means in the other end member which has an area substantially equal to the combined areas of all of said pressure relief hole means in said one end member.

24. The stun grenade of claim 23 wherein said means for reloading said housing with an explosive charge and for supporting a fuse member externally of said housing comprises collar means threadably engageable in a threaded central opening through said one end member, said plurality of pressure relief hole means in said one end member being circumferentially spaced around said threaded central opening, and said single pressure relief hole means in said other end member being in substantially coaxial alignment with said threaded central opening in said one end member.
