Definitions
- My improvement relates to the inclosing or boxing of the jaws of the ordinary or Gardner shackle with case-hardened or hardened steel boxes; the said boxes closely fitting the jaws, and closing in upon and to the ring or circle of the shackle, and then riveted through and through the box and jaws with a countersunk rivet.
- the object of the boxes is to prevent the convict from making the steel-hardened jaws of the Gardner or other shackle cut their own rivets, which may be done by placing the one-half of the jaw of a shackle on a solid bed or object and then striking the other half of the jaw until it is driven past its fellow sufli- 'The rivets are preferably countersunk.
