PROVISIONAL SPECIFICATION left by the said William Henry Latham
and Frederic Cartwright Ward Latham at the Office of the Com-
missioners of Patents, with their Petition, on the 6th February 1865.
We, WILLIAM HENRY LATHAM, Machinist, of Bolton, in the County of
Lancaster, and FREDERIC CARTWRIGHT WARD LATHAM, Printer, of the same
Place, do hereby declare the nature of the said Invention for "A New OR
IMPROVED MACHINE FOR TRIMMING OR CUTTING THE EDGES OF BOOKS, MAGAZINES,
AND SUCH LIKE ARTICLES," to be as follows:-
There is a circular knife fastened in a suitable manner upon a spindle
which revolves in two bearings with a pulley upon the spindle, by which the
circular knife may be actuated either by a pulley driven by a treadle or other
suitable manner. At that end of the spindle to which the knife is attached is.

Latham in the Great Seal Patent Office on the 4th August 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
HENRY LATHAM, of Bolton, in the County of Lancaster, Machinist, and
FREDERIC CARTWRIGHT WARD LATRAM, of the same Place, Printer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of February, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said William Henry Latham and Frederic Cartwright Ward Latham, Her
special licence that we, the said William Henry Latham and Frederic Cart-
wright. Ward Latham, our executors, administrators, and assigns, or such
others as we, the said William Henry Latham and Frederic Cartwright Ward
Latham, our 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 "A NEW OR IMPROVED MACHINE FOR
TRIMMING OR CUTTING THE EDGES OF BOOKS, MAGAZINES, AND SUCH LIKE ARTICLES,"
upon the condition (amongst others) that we, the said William Henry Latham
and Frederic Cartwright Ward Latham, our exccutors or administrators, by
an instrument in writing under our, 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 YF, that we, the said William Henry Latham and Frederic
Cartwright Ward Latham, do hereby declare the nature of the said Invention,

page_text: and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement and accompanying Drawings
(that is to say):-
Our Invention consists of a circular knife fastened in a suitable manner
upon a spindle which revolves in two bearings, with a pulley upon the spindle
by which the circular knife may be actuated either by a pulley driven by a
handle, treadle, or in any other manner. At that end of the spindle to which
the knife is attached is a moveable table sliding at right angles with the axes
of the knife. The material to be trimmed or cut is placed on this table with
the parts of the edges requiring to be cut overhanging the same. The table
slides accross the face of the knife, the knife at the same time rotating rapidly;
the edges of the paper requiring cutting are cut away in a much more expe-
ditious and regular manner than by the present method.
In order that the Invention may be better understood and explained in
detail, we have hereunto attached a Sheet of Drawings made upon a scale of
about two inches to the foot, and having similar letters of reference marked
upon corresponding parts in all the Figures.
Fig. is a side view of the machine for trimming or cutting the edges of
books magazines, and such like articles; Fig. 2 is an end view of the same;
Figs. 3 and 4 are diagrams showing the latch for putting the moveable table
in motion.
In Figs. 1 and 2, a, a, is the framing of the machine; b is the circular"
knife secured to the spindle c, to which motion is given from the handle e
by pulleys f, g, and h, secured to shafts i, j, and driven by the belts h, l.
The table m slides in the grooves n, n, across the axes of the knife b. The
presser o connected with the weighted lever p through the links q, q, holds
the books or magazines whilst being trimmed. The bracket r secured to
the table m carrying the weighted lever p by the stud s. Upon the curved
bracket is placed the spring catch u, which supports the weighted lever p,
and the presser o when raised up from the table during the time the work is
being changed, being the gauge. On lifting the latch (shewn in Fig. 3)
the spiral spring ht draws the strap fork gl, moving the belt Z from the loose
pulley a2 to the fast pulley a!, driving spur wheel 61 and spur wheel cl,
upon which a sliding block his carried by a stud of sliding in a slot in the
vertical lever 1, which is connected to the table m by means of the link el,
thus moving the table backwards and forwards. The latch on the return
motion of the table m presses against the incline pl (shewn in Fig. 4) upon
the strap fork g1, which stops the motion of the table. The glazier il is for
sharpening the knife, and is driven by pulley ji and belt kl, with lever II for

page_text: putting glazier in and out of contact with the knife by means of incline ml
attached to vertical lever d1.
Having thus described the nature of our said Invention, and the method
for carrying the same into practical effect, we desire it to be distinctly under-
stood that we claim as our Invention the revolving circular knife for trimming
the edges of books, magazines, and such like articles.
And, secondly, we claim the construction and general arrangement of the
various parts for effecting the desired object, as herein-before described, set
forth, and fully illustrated in the Drawings attached.
In witness whereof, we, the said William Henry Latham and Frederic
Cartwright Ward Latham, have hereunto set our hands and seals, this
Second day of August, in the year of Our Lord One thousand eight
hundred and sixty-five.
