IMPROVEMENTS IN SAWING MACHINERY
Year: 1859

page_text: LETTERS PATENT to Samuel Worssam, of Chelsea, in the County of
Middlesex, Engineer, for the Invention of "IMPROVEMENTS IN SAWING
MACHINERY."
Sealed the 6th March 1860, and dated the 9th September 1859.
PROVISIONAL SPECIFICATION left by the said Samuel Worssam at
the Office of the Commissioners of Patents, with his Petition, on the
9th September 1859.
I, SAMUEL WORSSAм, of Chelsea, in the County of Middlesex, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
SAWING MACHINERY," to be as follows:-
My Invention consists, first, in an improved feed for saw frames. I employ
an eccentric paul on a grooved wheel; the paul is connected to a lever, which
is keyed or otherwise fixed on the shaft or roller which drives forward the
wood to the saw.
Second, in the employment of vulcanized rubber springs to counterbalance
the crank used to drive the saw and the weight of the frame.
Third, in, working two saw frames together by the employment of two
connecting rods, carried up from two cranks on the driving shaft; each rod
being connected to the outside of the double frame.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Worssam in the Great Seal Patent Office on the
9th March 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
WORSSAM, of Chelsea, in the County of Middlesex, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of September, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Samuel Worssam, Her special licence that I, the said Samuel Worssam,
my executors, administrators, and assigns, or such others as I, the said
Samuel Worssam, 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 "IMPROVEMENTS IN
SAWING MACHINERY," upon the condition (amongst others) that I, the said
Samuel Worssam, 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.
NOW KNOW YE, that I, the said Samuel Worssam, 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 thereof, reference being bad to the Drawings hereunto
annexed, that is to say:-
Since the filing of my Provisional Specification, I have ascertained that the
second and third parts therein set forth of my improvements in sawing
machinery are not original, I therefore lay no claim to those parts.
I
My Invention now consists, first, in an improved feed for saw frames;
employ an eccentric paul or pauls on a grooved wheel, the paul or pauls is or are

page_text: connected to a lever, which is keyed or otherwise fixed on the shaft or roller
which drives forward the wood to the saw; and, second, in the employment
of a "sling" connecting rod for driving deal and other saw frames.
Figure 1 of the accompanying Drawings is a side, and Figure 2 an end
elevation of so much of a saw frame as will be necessary to explain my.
Invention. Figure 3 is a front, and Figure 4, a side elevation, on an enlarged
scale, of the feed wheel. Figure 5 is a front, and Figure 6 a side view of
one of the eccentric pauls; and Figures 7 and 8 are front and side elevations.
respectively of the "sling" connecting rod. The same letters of reference
indicate like parts in all the Figures.
A, A, is the main frame of the machine, which is firmly secured to the
foundation B; C is a horizontal shaft working in bearings D, D, secured to
the foundation B; this shaft C carries fast and loose pulleys E, E¹, and a fly-
wheel F. One end of the same shaft C is connected to a crank G, to which
the connecting rod H is keyed at one end and hung at or about the centre of
the frame I, I, at the other, in which frame the saws are fixed. This con-
necting rod is formed with a sling H' at its upper part, in order that the feed
rack may move through it. The said connecting rod works through the
frame I, I, and on motion being imparted to the fast pulley, the crank G
revolves, which through the connecting rod H gives a reciprocating motion to
the saw frame I, I. J is an eccentric, working round the shaft C; it is
embraced by a rod K, the opposite end of which works in a partially slotted
rod L, pivoted on a shaft M, which carries a grooved feed wheel N. The
opposite end of the rod L to that in which the rod K works, carries an
eccentric paul O which takes into the grooved feed wheel N. P is another
eccentric paul connected to the frame A, which also takes into the wheel N.
The shaft M on which the wheel N is mounted, carries a cog-wheel not shewn
in the Drawing, which takes into a rack fitted to the under side of the feed
table, or the shaft M is keyed to a roller or any other known agent, whereby
the table can be carried forward. The reciprocating motion which the rod K
imparts through the eccentric J to the rod L, causes the eccentric pauls O
and P alternately to grip the grooved wheel N, which revolves slowly and
carries with it the carriage and timber, regularly forward towards the saw.
The feed can be regulated by altering the position of the rod K in the slotted
lever L, so that any desired speed can be given to the timber, according to
the nature of the wood to be cut. Instead of the wheel being grooved, I'in
some cases groove the paul or pauls, and form the periphery of the feed wheel
of a A shape.

page_text: And having now described the nature of my said Invention and in what
manner the same is to be performed, I declare that I claim as my improve-
ments in sawing machinery:-
First, the improved feed for saw frames, herein-before described and illus-
trated in the accompanying Drawings.
And, second, the employment of a sling connecting rod for driving deal and
other saw frames, as herein-before described and illustrated in the accom-
panying Drawings.
In witness whereof, I, the said Samuel Worssam, have hereunto set my
hand and seal, this Ninth day of March, in the year of our Lord
One thousand eight hundred and sixty.
HAD
SAMUEL WORSSAM. (S.)
