in the County of York, for the Invention of "AN IMPROVED 'BENCH DOG'
OR BENCH HOOK.'"
Sealed the 24th December 1867, and dated the 1st July 1867.
PROVISIONAL SPECIFICATION left by the said Frederick Towns Pollard
at the Office of the Commissioners of Patents, with his Petition, on
the 1st July 1867.
I, FREDERIO TOWNS POLLARD, of Holbeck, near Leeds, in the County of
York, do hereby declare the nature of the said Invention for "AN. IMPROVED
BENCH DOG' OR 'BENCH HOOK,'" to be as follows:-
My Invention has for its object the obtaining a thoroughly firm hold or
nip of the article under operation, as it is well known in practice that those
dogs or hooks in general use are defective in this respect. For this purpose
underneath the bench I affix in a convenient position a bracket adapted to
carry a short shaft. To the outer end of the shaft I secure a small pulley or
handle, and on the inner end an eccentric cam which may be made somewhat
similar to those used in sewing machines. Within the groove of the cam
works a pin which is secured to the stem of the "dog" or "hook," such stem
being by preference of cast iron, hollow and square, working vertically in a
box let into the bench and secured by screws to the "bench" or "hook."
I am thus enabled readily to regulate the height of the dog or hook (which is

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
TOWNS POLLARD, of Holbeck, near Leeds, in the County of York, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of July, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Frederick Towns Pollard, Her special licence that I,-the-said- Frederick
Towns Pollard, my executors, administrators, and assigns, or such others
as I, the said Frederick Towns Pollard, my executors, administrators, 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
"AN IMPROVED BENCH DOG OR BENCH HOOK," upon the condition (amongst
others) that I, the said Frederick Towns Pollard, my executors or adminis-
trators, 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.
.
NOW KNOW YE, that I, the said Frederick Towns Pollard, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by
the following statement :-
My Invention has reference to the construction of an improved bench, dog
or bench hook for holding work. whilst being operated upon, whether such
work be of greater or lesser thickness. The work to be operated upon may
be held by the workman thrusting the work up against the teeth of the
holder, as in the common joiners' bench hook, or by the work being put
between the holder and the bench and nipped to the bench by turning the

page_text: band wheel. To this: end I adopt the following. mechanical arrangements,.
which are illustrated by the Diawings accompanying these Presents, and are.
referred to by the letters of reference' hereafter mentioned.

DESCRIPTION OF THE. DRAWINGS.

(Fig. 1). A band wheel A is secured on the spindle B; passing through.a
collar A' attached to a pendant A2-secured to or forming part of the securing
plate A³, by which the apparatus, can be screwed to, the bench top; C, a
circular plate secured on the same spindle B as the hand wheel. Sometimes
I have the hand wheel, scroll plate, and spindle all cast together, forming one
piece, to suit which the pendant is provided with a cap, as shewn in Fig:8;
As being the pendant and a the cap; C¹ (see Fig. 2), is a scroll groove on one
side of the said scroll plate, having a pin C working therein, such pin being
attached to the upright piece D which works in the guide box E, secured to
or forming part of the securing plate A', such upright piece being provided
with holder F. The aforesaid pin C is provided with two nuts K and L, as
shewn in Fig. 4, so that should the pin end become much worn by usage and
the nut L slackened and the nut K screwed tight up, would set the pin end
farther into the groove, filling in and not allowing much play. I use two
kinds of guide boxes; thus in one apparatus, as in Fig. 5, the guide box
extends nearly through the bench top; in another, as in Fig. 6, no portion of
the guide box is above the securing plate, the hole in the bench top forming a
guide for the top of the upright piece D. Also I use two kinds of upright
pieces, one of iron with a recess in the back, which upright piece is well fitted
into the guide box, Fig. 5, so that it will just slide up and down. A piece of
wood is fitted into the recess at the back of the upright piece, projecting a
little farther out than the iron back of the upright piece, which prevents the
upright piece shaking in the box, as shewn in Figs. 7 and 8; the other
upright piece is of wood, and is fitted into the box, Fig. 6. Instead of the
holder F I can use two other holders, namely, that shewn in Fig. 9 and that
shewn in Fig. 10, Fig. 9 being screwed on to the front side of the upright D.
and Fig. 10 being screwed into the top of the upright D to nip the work to
the bench. The space X in Fig. 1 is to allow the upright with pin C
attached to be lifted out of the box when required. The scroll groove should
be made rather wider at the outside and the pin made taper to suit. The
workman by turning the hand wheel A tarns the circular plate C, which acts
upon the pin C, thus raising or lowering the upright piece D, and by con-
sequence raising or lowering the holder F above mentioned. A hole is to be
made through the bench top so that the part E may be put through from

page_text: beneath or through which the upright may work, then the apparatus can be
secured to the bench.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed, I hereby declare
that I claim the improved bench dog or bench hook actuated by the
mechanical arrangements herein-before described.
In witness whereof, I, the said Frederick Towns Pollard, have hereunto
set my hand and seal, this 27th day of December, One thousand eight
-hundred and sixty-seven.
Witness,
JOSEPH LONGFIELD.
