PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Parallel Vices.
I, WILLIAM DANGERFIELD of No. 23 Bell Street Darlaston in the County of
Stafford Tool Maker do hereby declare the nature of this invention to be as
follows:-
In the manufacture of this improved parallel vice, the parts called the plate and
the back jaw, are cast or otherwise made in one solid piece, doing away with the
pins and buttons that are usually required to secure the said plate and back jaw
together.
The body or slide is grooved in the usual way for the boss to work along, and
into which the pin is wormed to draw the jaws together, except that the groove is
continued right to the back end of the said body or slide, so that when the pin is
turned out of the boss the body and front jaw may be taken out of its position, and
becomes loose from the other part of the vice, thus doing away altogether with the
use of pins and buttons.
Dated this 23rd day of December 1895.

1, WILLIAM DANGERFIELD of No. 23 Bell Street Darlaston in the County of
Stafford, Tool 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 :-
In the manufacture of this improved parallel vice the parts called the plate and
back jaw are cast or otherwise made in one solid piece, doing away with the pins
and buttons that are usually required to secure the plate and back jaw together.
The body or slide is grooved in the usual way for the boss to work along and into
which the pin is wormed to draw the jaws together, except that the groove is
continued right to the back end of the said body or slide, so that when the pin is
turned out of the boss the body and front jaw may be taken out of its position and
becomes loose from the other part-of the vice, thus doing away altogether with the
use of pins and buttons.
I will now describe it in connection with the accompanying sheet of drawings.
The same letters of reference occuring on different figures indicate corresponding
parts.
Fig. 1. is a side view of this improved parallel vice. Fig. 2. is a section of same
and Fig. 3. is a cross section through the back jaw and plate.

page_text: A is the back jaw that is cast or otherwise made in one piece with the plate B
(that the vice rest upon when fixed for use to a bench by means of the screws D. D)
as will be seen by Fig. 3.
The body or slide E is made with the end open as E' so that when the pin F,
by means of the handle bar G, is turned out of the boss H, the body or slide E
may be detached altogether from the back jaw A and plate B. The hole I Fig. 3. is
the receptacle for the pin F and is wormed with the pin F, by means of which the
jaws A and K of the vice are drawn together. The hole J. Fig. 3 is the part
wherein the slide E passes through the back jaw A.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
.claim is :
1st. The construction of a parallel vice wherein the back jaw and the plate are
made in one solid piece as herein before described.
2nd. The construction of a parallel vice wherein the body or slide has the back
end open as herein before described.
3rd. The construction of an improved parrallel vice substantially the same as
shown and described in this specification and the sheet of drawings accompanying
:the same.
Dated this 23rd day of September 1896.
