I ROBERT CAUNCE of No. 126 Queen's Walk in the Town of Nottingham
Gentleman do hereby declare the nature of this invention to be as follows:-
The improvement consists in the addition to the Carrier or Dog of a perforated
Bar to form a guide and holder for the nipping-screw for the purpose of retaining
the projected portion of such screw in a state of fixity when applied and screwed up
to the material to be carried, the Carrier or Dog being shaped in such a manner as
to allow of the said Bar sliding up and down with and on or without the screw and
the end of the screw (plain or threaded) passing through the Bar.

Figure 1 represents a front and back view of my improved apparatus.
Figure 2 represents a vertical section of figure 1 from front to back.
Figure 3 represents a plan of the screw end of the lathe-dog with the screw
removed.
Figure 4 represents the sliding bar guide.
Figure 5 is a horizontal section of the stalk of the lathe-dog.
Figure 6 is a plan of the sides of the screw head.
The corresponding parts in each figure are indicated by the same letters where
necessary.
A represents the principal frame of the apparatus.
B is the screw with which to nip or press the material to be worked against the
V in E.
C is the sliding bar guide which, together with the making of the inner sides of the
carrier parallel and adjustment of screw passing through the slide, constitutes my
improvement in the lathe-dog.
G are the nibs of sliding bar guide and are nearly in contact with the frame A
and so prevent the slide getting out of position laterally.
H shows the curves of slide the outer portion of which is nearly in contact with the
inner portion of E and so prevent any transverse motion.
K shows the portion of the screw passing through the guiding bar the screw being
adjusted to work with sufficient freedom in the slide.
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 addition to the Lathe-Dog of the sliding bar guide (through which the nipping
screw passes) in conjunction with the parallel sides of the dog.
