Claims
- 1. The combination of a socket wrench adapted for application of torque limiting frangible fasteners having a flatted wrenching collar of narrow height, said wrench having at least one socket sleeve of substantially greater depth than the height of said wrenching collar distally carried on a wrench body with a through aperture having unbroken, smooth-walled indexing flats for mating with said flatted wrenching collar and with an internal lip at one end thereof, and;
- a. a cylindrical member having a cylindrical body with an external diameter closely conforming to the internal diameter of said socket sleeve and a length sufficient to fill at least 50 percent of the depth of said socket sleeve and leave an unfilled depth substantially equal to the height of said narrow collar, said member being slidably received within said socket sleeve and having a reduced diameter neck at one end to form an annular shoulder with said cylindrical body, and said neck having a length at least equal to the width of said narrow wrenching collar; and
- b. A ring permanently secured to the outer end of said reduced diameter neck whereby said internal lip of said socket sleeve is captured between said annular shoulder and said ring, thereby slidably retaining said cylindrical member in said socket sleeve.
- 2. The socket wrench of claim 1 wherein said cylindrical member is a hollow sleeve.
- 3. The socket wrench of claim 2 wherein said annular shoulder is axially spaced from said ring by a distance substantially greater than the thickness of said internal lip to permit axial sliding of said cylindrical member in said socket sleeve.
- 4. The socket wrench of claim 1 wherein said socket sleeve is rotatably carried on said wrench body.
- 5. The socket wrench of claim 1 including ratchet teeth disposed about the exterior of said socket sleeve and a cooperative pawl carried by said wrench body.
- 6. The socket wrench of claim 5 including spring means biasing said cooperative pawl into engagement with said ratchet teeth.
- 7. The socket wrench of claim 5 wherein said cooperative pawl is pivotally mounted in said wrenching body for reversal between positions engaging said ratchet teeth against clockwise, and counterclockwise rotation.
- 8. A socket sleeve and adapter received within said socket sleeve to adapt said socket sleeve for for application of torque limiting frangible fasteners having a flatted wrenching collar of narrow height, which comprises:
- a: a socket sleeve having substantially greater depth than the width of said wrenching collar, and a through aperture with indexing flats on its internal wall for mating with said wrenching collar and an internal lip at one end thereof; and
- b: a cylindrical adapter member having an external diameter closely conforming to the internal diameter of said aperture of said socket sleeve and received therein, and having a length at least equal to 50 percent of the depth of said socket sleeve and leaving an unfilled depth substantially equal to the height of said narrow collar, said adapter member being slidably received within said socket sleeve and having a neck of a reduced diameter to provide an exterior annular shoulder and a length at least equal to the height of said narrow collar; and
- c: a ring permanently secured to the outer end of said neck whereby said internal lip of said socket sleeve is captured between said annular shoulder and said ring, thereby slidably retaining said cylindrical adapter member in said socket sleeve.
- 9. The socket wrench of claim 8 wherein said annular shoulder is axially spaced from said ring be a distance substantially greater than the thickness of said internal lip to permit axial sliding of said cylindrical member in said socket sleeve.
