Improvements in Screw Boxes for Vices, Cramps, and similar Tools.
I, JOSEPH CASE of No. 268, St. Philip's Road, Sheffield, in the County of York,
do hereby declare the nature of my invention for IMPROVEMENTS IN SCREW BOXES FOR
VICES, CRAMPS AND SIMILAR TOOLS, to be as follows:-
My improvement consists in making such Screw Boxes reversible, so that when
they are worn out or broken at one end, they are still available for work, by simply
turning them with the other end towards the pull and wear of the Screw.
I make the said boxes of any suitable metal and either by casting or forging or
by a combination of casting and forging as may be preferred, and likewise I either
cut the threads out of the solid, put in separate bushes or worms brazed or fastened
in as at present is well understood.
In making a wrought Iron box according to my invention for a common Bench
vice, I proceed as follows, I make by welding or forging, one end of the Box
corresponding to the front end of an ordinary box as far as the collar which sustains
the pull against the back of the vice, I then make a second end exactly.similar and
fasten the two together at the collars either by welding, by Screws or by pins etc.,
having first formed the Screw threads inside and left clearance between them. Then
over the back end of the box, I fit and attach a sleeve or socket cover to give all a
more finished appearance and also to prevent any dirt etc. from getting into the
unused end.
The Cast Boxes I make in a similar manner and either all in one piece, or of two
pieces joined together as before described, and I complete as before with a sleeve
cover.

I JOSEPH CASE of No. 268, Saint Philip's Road, Sheffield, Vice Maker, do hereby
declare the nature of this invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
My improvement consists in making such Screw Boxes reversible, so that when
they are worn out or broken at one end they are still available for work by simply
turning them with the other end towards the pull and wear of the Screw.
I make the said Boxes in any suitable Metal, and either by Casting or Forging or
by a combination of Castings & Forgings as may be preferred. And likewise I
either cut the threads out of the solid, put in separate bushes or worms brazed or
fastened in, as at present is well understood.
In making a wro't Iron Box according to my invention for a common bench vice, I
proceed as follows. I make by welding or forging one end of the box corresponding
to the front end of an ordinary box as far as the Collar which sustains the pull against
the back of the vice. I then make a second end exactly similar and fasten the two
together at the collars either by welding, by Screws or by pins etc. having first
formed the screw threads inside & left clearance between them. Then over the back
end of the box I fit and attach a sleeve or socket cover to give all a more finished
appearance and also to prevent any dirt etc. from getting into the unused end.
The cast boxes I make in a similar manner, and either all in one piece, or of two
pieces joined together as before described and I complete as before with a sleeve
cover.
And in order that my said Invention may be more clearly understood, I have
annexed hereunto a Sheet of Drawings illustrative thereof, and have marked the same
with Figures & letters of reference, the same letter referring to the same part in all
the corresponding Figures.
Fig. 1. is an Elevation of a complete Vice Box.
Fig. 2. is an End view of the same &
Fig. 3. is a Longitudinal Section of ditto.

my Invention.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed, I declare that what I claim is.
The formation of a Screw Box in parts fastened together or in one piece, in such
manner that only one portion or end of the box is subjected to wear and strain leaving
the other end ready & available for reversal and use whenever required.
