IMPROVEMENTS IN SUSPENDERS OR · BEARERS FOR TUBES, RODS, WIRE, OR OTHER EQUIVALENTS
Year: 1874

page_text: LETTERS PATENT to Ebenezer Entwistle, of Blackburn, in the County
of Lancaster, for the Invention of "IMPROVEMENTS IN SUSPENDERS OR
· BEARERS FOR TUBES, RODS, WIRE, OR OTHER EQUIVALENTS.”
Sealed the 26th February 1875, and dated the 26th September 1874.
PROVISIONAL SPECIFICATION left by the said Ebenezer Entwistle at
the Office of the Commissioners of Patents, with his Petition, on
the 26th September 1874.
I, EBENEZER ENTWISTLE, of Blackburn, in the County of Lancaster,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN SUSPENDERS OR BEARERS FOR TUBES, RODS, WIRE, OR OTHER EQUIVALENTS,” to
be as follows :—
This Invention has for its object improvements in suspenders or
bearers for tubes, rods, wire, or other equivalents, whereby much greater
facility is obtained in imparting motion to any object at any required
distance.
Hitherto it has been the practice in suspending or supporting tubes,
Leon the GAMA An

page_text: grooved pulleys, and to enable them to be moved backwards and for-
wards it requires a weight at one end sufficient to draw it forward, and
to draw it back again it requires sufficient power not only to draw back
the tube, rod, or wire itself, but also the weight that has previously
drawn it forward; the weight and the friction on the pulleys causes it 5
to require equal to 3 times the weight that drew it forward in the first
instance, in order to be able to reverse it.
Now in order to obviate these disadvantages I proceed as follows:-I
take a tube, rod, or wire, or its equivalent, and I connect each end
thereof by a stud or other suitable means to the bottom of a link, such 1
link being suspended perpendicularly from a stud bracket or its equi-
valent, secured to a post or any suitable support. The said links acting
as levers fall perpendicularly and sustain half the weight in moving,
according to the length and motion required, and to move the tube, rod,
or wire, from the perpendicular position requires only half the power in 1
proportion to that which is required in first drawing the tube, rod, or
wire on pulleys, and the weight of such tube, rod, or wire, is in itself
sufficient to cause such links to fall back to their original perpendicular
position. Thus assuming the first moving weight of the tube, rod, or
wire, when supported on pulleys to be 100 lbs., in order to impart full 2
motion both ways a weight of 300 lbs. would be required, whereas by
adopting my improved construction of suspender or bearer, as above
described, only a weight of 50 lbs. is required to give full motion both
ways to the tube, rod, or wire.
The novelty of this my Invention consists in the method of con- 2
necting tubes, rods, or wire to links or equivalents, instead of bearing
or supporting them on grooved pulleys, thereby greatly diminishing
the power requisite to impart motion to any object at any required
distance, which in itself is a most important advantage.

filed by the said Ebenezer Entwistle in the Great Seal Patent Office
on the 25th March 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EBENEZER
ENTWISTLE, of Blackburn, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of September, in the
year of our Lord One thousand cight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Ebenezer Entwistle, Her special
license that I, the said Ebenezer Entwistle, my executors, administrators,
and assigns, or such others as I, the said Ebenezer Entwistle, my exe-
cutors, 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 SUSPENDERS OR BEARERS FOR TUBES, RODS, WIRE, OR
OTHER EQUIVALENTS," upon the condition (amongst others) that I, the
said Ebenezer Entwistle, my executors or administrators, by an instru-
ment 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 Ebenezer Entwistle, do hereby declaro
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, that is to say :-
This Invention has for its object improvements in suspenders or
bearers for tubes, rods, wire, or other equivalents, whereby much greater
facility is obtained in imparting motion to any object at any required

page_text: Hitherto it has been the practice in suspending or supporting tubes,
rods, or wires, and such like machinery, to support or bear the same on
grooved pulleys, and to enable them to be moved backwards and for-
wards it requires a weight at one end sufficient to draw it forward, and
to draw it back again it requires sufficient power not only to draw back
the tube, rod, or wire itself, but also the weight that has previously
drawn it forward; therefore the weight and the friction on the pulleys
causes it to require equal to three times the weight that drew it forward
in the first instance in order to be able to reverse it.
Now in order to obviate these disadvantages I proceed as follows:—I
take a tube, rod, or wire, or its equivalent, and I connect each end
thereof by a stud or other suitable means to the bottom of a link, such
link being suspended perpendicular from a stud bracket or its equi-
valent secured to a post or any suitable support. The said links acting
as levers fall perpendicularly and sustain half the weight in moving,
according to the length and motion required, and to move the tube, rod,
or wire from the perpendicular position requires only half the power in
proportion to that which is required in first drawing the tube, rod, or
wire on pulleys, and the weight of such tube, rod, or wire is in itself
sufficient to cause such links to fall back to their original perpendicular
position. Thus assuming the first moving weight of the tube, rod, or
wire when supported on pulleys to be 100 lbs., in order to impart full
motion both ways a weight of 300 lbs. would be required, whereas by
adopting my improved construction of suspender or bearer, as above
described, only a weight of 50 lbs. is required to give full motion both
ways to the tube, rod, or wire.
The novelty of this my Invention consists in the method of con-
necting tubes, rods, or wires to links or equivalents, instead of bearing
or supporting them on grooved pulleys, thereby greatly diminishing
the power requisite to impart motion to any object at any required
distance, which in itself is a most important advantage.
But in order to elucidate all the parts of this my Invention more fully
I proceed as follows:-In the first place I shall give a description of the
Drawings; secondly, a detailed description of all the Figures, &c., as
shewn in the Drawings; thirdly, their connections; fourthly, their
workings; fifthly, the leading features; sixth and lastly, what I claim
as the novelties of this my Invention.

page_text: SIXTHLY, AND LASTLY.
Having thus fully described the nature and particulars of this my
Invention, and the manner of carrying the same into effect, I desire it
to be distinctly understood that I do not confine myself to the exact
details herein set forth, as such may be varied and modified without
departing from the principle thereof; but what I claim as my Inven-
tion, and which to the best of my knowledge and belief has not been
hitherto used within this realm, is the method of suspending or bearing
tubes, rod, wires, or equivalents, by link d, and all other connections,
and all such improvements thereon, as herein described and set forth 1
in the accompanying Drawings.
In witness whereof, I, tho said Ebenezer Entwistle, have hereunto
set my hand and seal, this Twenty-second day of March in
the year of our Lord One thousand eight hundred and seventy-
five.
