Year: 1852

page_text: LETTERS PATENT to Jacob Tilton Slade, of Pall Mall, in the County
of Middlesex, Gentleman, for the Invention of "AN IMPROVED MODE
OF DRIVING CERTAIN MACHINES, AND AN IMPROVED DRIVING BAND OB
CHAIN TO BE USED THEREWITH."
Sealed the 23rd March 1853, and dated the 6th October 1852.
PROVISIONAL SPECIFICATION left by the said Jacob Tilton Slade
at the Office of the Commissioners of Patents, with his Petition,
on the 6th October 1852.
I, JACOB TILTON SLADE, do hereby declare the nature of the. said
3 Invention for "AN IMPROVED MODE OF DRIVING CERTAIN MACHINES, AND
AN IMPROVED DRIVING BAND OR CHAIN TO BE USED THEREWITH," to be as
follows:-
I drive a series of machines requiring circular motion by means of a
band or chain passing partly or entirely round the driving drum of each
.machine in the series, instead of driving each of such machines by a
separate band actuated by a shaft. The improved chain is shown on
the Drawing, and will work at right angles, if required, by having each

filed by the said Jacob Tilton Slade in the Great Seal Patent
Office, on the 6th April 1853.
TO ALL TO WHOM THESE. PRESENTS SHALL COME, I,
JACOB TILTON SLADE, of. Pall Mall, in the County of Middlesex, Gentle-
man, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of October, in the year of
our Lord One thousand eight hundred and fifty-two, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Jacob Tilton Slade, Her special licence.
that I, the said Jacob Tilton Slade, my executors, administrators, and
assigns, or such others as I, the said Jacob Tilton Slade, 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, ex-
ercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "AN_
IMPROVED MODE OF DRIVING CERTAIN MACHINES, AND AN IMPROVED DRIVING
BAND OR CHAIN TO BE USED THEREWITH," upon the condition (amongst
others) that I, the said Jacob Tilton Slade, by an instrument in writing
under my hand and seal, 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 Jacob Tilton Slade, do hereby
declare the nature of said Invention, and in what manner the same!
is to be performed, to be particularly described and ascertained in and:
by the following statement (that is to say):

page_text: My Invention relatès,
First, to giving motion to the driving pulleys or drums of a series of
machines requiring circular motion by means of one driving band or
chain, in place of driving each machine by a separate strap actuated by
a common shaft.
And, secondly, my Invention relates to the construction of a driving
band or chain the parts of which are capable of turning on axes at
right angles to those adjoining, and which is adapted to giving motion
to a series of pulleys or drums on the driving axes of a series of
machines placed at angles to each other.
In order that the Invention may be fully understood I will proceed
to describe the means pursued by me.
DESCRIPTION OF THE DRAWING. -
Figure 1, shows a plan. Figures 2, and 3, two elevations of parts
arranged for carrying out my improvements. a, is the main shaft or
axis, to which motion is given by means of a steam engine or other
suitable power. Upon this axis a, is affixed the drum or pulley b, over
which passes the endless band or chain c, which also passes partly around
the various drums or pullies e, e, e, which pulley "ör drum e, being
mounted either upon the main axis of a separate machine requiring to
have circular motion imparted to it, or upon an axis connected by a
suitable clutch box to the main axis of each separate machine, which is
the simplest plan, and that which I prefer to adopt.
I have shown a lathe in connection with one of the drums or pulleys
e; and it will be seen that the main shaft f, thereof is capable of being
connected with the shaft of that pulley e, so as to be driven thereby by
means of the clutch box g; and in like manner may each of the shafts
or axes of the other drums or pulleys e, be caused to drive separate
lathes, or in place of lathes the drums or pulleys e, may be caused to
drive the main shaft or axes of other machines requiring circular motion.
The drum or pulley h, has an adjustable bearing, so as to regulate the
tension of the driving band or chain used.
In the Figures 1, 2, and 3, I have shown an ordinary leather or
other band c; and it will be evident that if a chain or other jointed band

page_text: be used, such must be capable of turning readily in various directions;
and it is to the construction of a chain or other jointed band adapted to
such circumstances that the second part of my Invention relates, and
which I will now briefly describe by reference to Figures 4, and 5.
i, j, k, are the separate parts or links, which are jointed together at I, 1,
and m. The joints connecting the links i, j, it will be seen, admit of
their turning at right angles to the next adjoining ones, and chains or
bands thus formed will be found peculiarly adapted to drive a series
of drums or pullies arranged at angles to each other, in like manner
to those described under the first head of the Invention.
Having thus described the nature of my said Invention, I would have
it understood that I do not confine myself to the various details so long
as the peculiar character of either part be retained.
In witness whereof, I, the said Jacob Tilton Slade, have here-
unto set my hand and seal, this Fifth day of April, in the year
of our Lord One thousand eight hundred and fifty-three.
Witness,
