Year: 1857

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street, in
the City of London, E. C., Editor of the Mechanics' Magazine, and
Patent Agent, for the Invention of "IMPROVEMENTS IN VICES."-A com-
munication from Manciaux Nullio
Sealed the 1st January 1858, and dated the 7th July 1857.
PROVISIONAL SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his
Petition, on the 7th July 1857.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, E. C., Editor of the Mechanics' Magazine, and Patent Agent, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN VICES,"
(communicated to me by Monsieur Neullies, a foreigner residing abroad,) to
be as follows:-
This Invention consists in the employment of a washer placed between the
jaws of the vice and the ends of the screw, for affording a direct pressure and
complete support to the screw. It may be applied to vices manufactured for
the purpose as well as to vices already constructed.
Figure 1 shews the Invention applied to a vice constructed for its reception,
and Figures 2 and 3 shew it fitted to an ordinary vice.
In Figure 1, a is the washer or friction piece, which must be supposed to be
solid, with the head 6 of the screw c. It is maintained against the head
by a spring d entering the groove e; the eye 9 in the jaw h is hollowed out

page_text: spherically to receive the spherical end of the washer or friction piece a.
Experience has shewn that vices wear at the eye of the moveable jaw, and
this Invention by preventing such wear will increase their durability. A similar
arrangement to that shewn at Figure 1 may be adapted to the opposite jaw
and end of the screw. Figure 2 is a view of so much of an ordinary vice as
is necessary to illustrate this Invention. a is the washer in the position it
occupies in the vice, and in Figure 3 it is shewn in section detached. The
washer is straight upon its face or portion which is next the eye in the jaw,
instead of being spherical as in the washer first described. The washer or
friction piece a is fixed to the eye b of the jaw, and is maintained in position
by the tenon c, which fits into a recess formed in the jaw.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brouman, in the Great Seal Patent
Office on the 7th January 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, E.C.,
Editor of the Mechanics' Magazine, and l'atent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of July, in the year of our Lord One
thousand eight hundred and fifty-seven, in the twenty-first year of Her reign,
did, for Herself, IIer heirs and successors, give and grant unto me, the said
Richard Archibald Brooman, Her special licence that I, the said Richard
Archibald Brooman, my executors, administrators, and assigns, or such
others as I, the said Richard Archibald Brooman, my executors, adminis-
trators, and assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term therein expressed, should
and lawfully might make, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN VICES," (a communication from Monsieur
Neullies,) upon the condition (amongst others) that I, the said Richard
Archibald Brooman, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Richard Archibald Brooman, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement thereof, reference being had to the Drawings hereunto
annexed (that is to say):-
This Invention consists in the employment of a washer placed between the
jaws of the vice and the ends of the screw, or of two washers, one outside of
cach jaw, for affording a direct pressure and complete support to the screw. The
washers may be applied to vices manufactured for the purpose as well as to
vices already constructed.
Figures 1 and shew the Invention applied to a vice constructed for its
reception in side and plan views respectively; and Figures 3, 4, 5, and 6, are
detached views of the parts employed; Figure 7 shews the improvements
applied to an ordinary vice; and Figures 8, 9, and 10, are detached views of
the parts employed in this case.
In Figures 1 and 2, a is the washer or friction piece, which must be
supposed to lie solid in a recess formed in the head of the screw c; the
head b is maintained against the washer a by a spring d entering the groove e;
the outer edge of the eye, which is formed at g in the jaw h, is hollowed out
spherically to receive the spherical part of the washer or antifriction piece a.
Figures 3 and 4 are respectively front and back views of the washer a;
Figure 5 is an edge view of the same; and Figure 6, a section.
Experience has shown that vices wear at the eye of the moveable jaw, and
this Invention by preventing such wear will encrease their durability. A similar
arrangement to that shewn at Figures 1 and 2 may be adapted to the back of
the opposite jaw; Figure 7 is a view partly in section of so much of an
ordinary vice as is necessary to illustrate this Invention; a is the washer shewn
in section in the position it occupies in the vice; Figures 8 and 9 are front
and back views of the washer a, detached; and Figure 10 is a section of the
The washer is straight upon its face, or the portion which is next the
eye in the jaw, instead of being spherical, as in the washer first described. The
washer or antifriction piece a is kept up to the eye b, and is maintained in
position by the tenon c, which fits into a recess formed in the back of the
jaw.
same.
Figure 11 shews a portion of a vice with antifriction washers of a different
form applied thereto; A, A', are the washers, with a portion broken away to
shew their peculiar form. The faces of these washers, which are placed next
the jaws, are flat, so that they may lie solid to the front of one jaw and back
of the other, as at a and b; notches c, c, are formed in the flat faces of these

page_text: washes, to take on to pins or projections d, d, which pins or projections are
screwed into or formed on the back and front of the jaws C and D. By the
notches c, c, in the washers A, A¹, taking on to the pins or projections d, d,
they are prevented from turning round while the screw is made to revolve by
the lever; and to prevent the screw box F from turning, a feather is sunk in,
or a projection is formed on its under side, which feather or projection takes
into a notch or slot f, cut, cast, or otherwise formed in the washer A¹, as shewn
in Figure 12, which is a front view; Figure 13 is a back view of this washer
A', which is applied to the back of the vice; Figure 14 is a section of the
same through the lines g, h; and Figure 15 is another section taken through
the lines i, j, at right angles to that in Figure 14. The washer A which is
placed on the front of the vice jaw C, is similar to the washer A', but with the
following exception, viz., the eye or hole is of less size to allow the screw
to pass through instead of the screw box F, and the notch or slot f is dis-
pensed with. From the foregoing description, with reference to the Drawings,
it will be seen that the shoulders of the screw rod and screw box will always
have the strain taking place on their centres, instead of being thrown on
to their edges as in ordinary vices, whereby unnecessary tear and wear are
prevented. G, G¹, are hoops or rings which are shrunk on or otherwise
secured to the washers A and A¹, or they may be cast or formed in a piece
with them; these hoops project over the shoulders of the screw and screw
box (when they are in place), to prevent filings, dust, or other matters
from entering between the shoulders and washers.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim as the improve-
ments in vices the employment therein of a washer or of washers in manner
and for the purpose herein-before described.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Seventh day of January, One thousand
eight hundred and fifty-eight.
