page_text: LETTERS PATENT to James Norris, of the Firm of Charles Jeakes and
Company, of 51, Great Russell Street, Bloomsbury, in the County of
Middlesex, for the Invention of "IMPROVEMENTS IN HYDRAULIC, STEAK,
AND OTHER LIRTS BOD RAYOTER DAGO Coong"
Sealed the 8th May 1866, and dated the 11th November 1865.
PROVISIONAL SPECIFICATION left by the said James Norris at the
Office of the Commissioners of Patents, with his Petition, on the
11th November 1865.
I, JAMES NORRIS, of the Firm of Charles Jeakes and Company, of 51,
Great Russell, Bloomsbury, in the County of Middlesex, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN HYDRAULIC,
STEAM, AND OTHER LIFTS FOR RAISING PASSENGERS OR GOODS," to be as
follows:-
This Invention relates to improved arrangements of the balance weights
and the chains which connect them to the room or cage in which the
passengers or goods are raised up or lowered down the well or shaft of
hydraulic or other "lifts." Heretofore it has been the practice to attach
the end of the chain (which connects the balance weight or weights and
the lifting chamber together) to the roof or cover of the lifting room or
chamber employed for raising or lowering the passengers or goods. In
consequence of this arrangement serious and fatal accidents have resulted.

page_text: from the breaking of the chain or its support, which by falling down the
shaft upon the roof of the lifting room have crushed it in, thus killing and
injuring the occupants. Now, in order to avoid the risk hitherto con-
sequent upon the occurrence of such accidents, I attach the balance
weight chain or chains to arms which project from the sides of the lifting
room or parts connected therewith, such arms moving up and down in
grooves or guides formed in the sides of the shaft. Friction rollers are
also attached to the "lift," by preference formed with bevilled sides and
travelling up and down in guides of corresponding form, so that the rollers
may at all times act in the guides should the lift move sideways in either
direction. By thus arranging the connection of the "lift" with the
balance weight or weights all overhead gear in the shaft of the "lift" is
dispensed with.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Norris in the Great Seal Patent Office on the
11th May 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
NORRIS, of the Firm of Charles Jeakes and Company, of 51, Great
Russell Street, Bloomsbury, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of November, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-ninth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said James Norris, Her special licence that I, the said James
Norris, my executors, administrators, and assigns, or such others as I, the
said James Norris, 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 HYDRAULIC, STEAM, AND OTHER LIPTS' FOR RAISING
PASSENGERS OR GOODS," upon the condition (amongst others) that I, the
said James Norris, 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

page_text: 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 James Norris, do hereby declare 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 relates to improved arrangements of the balance weights
and the chains which connect them to the room or cage in which the pas-
sengers or goods are raised up or lowered down the well or shaft of
hydraulic or other "lifts." Heretofore it has been the practice to attach
the end of the chain (which connects the balance weight or weights and.
the lifting chamber together) to the roof or cover of the lifting room or
chamber employed for raising or lowering the passengers or goods. In
consequence of this arrangement serious and fatal accidents have resulted
from the breaking of the chain or its support, which by falling down the
shaft upon the roof of the lifting room have crushed it in, thus killing of
injuring the occupants. Now, in order to avoid the risk hitherto conse-
quent upon the occurrence of such accidents, I attach the balance weight
chain or chains to arms which project from the sides of the lifting room
or parts connected therewith, such arms moving up and down in grooves
or "guides" formed in the sides of the shaft. Friction rollers are also
attached to the "lift," by preference formed with bevelled sides and
travelling up and down in guides of corresponding form, so that the rollers
may at all times act in the guides should the lift move sideways in either
direction. By thus arranging the connection of the lift with the balancé
weight or weights all overhead gear in the shaft of the "lift" is dispenséd
with.
And in order that my said Invention may be better understood and
readily carried into practice, I will proceed to describe the Drawing
hereunto annexed...
DESCRIPTION OF THE DRAWING.
Figures 1 and 2 show vertical sections of an hydraulic "lift" for raising
and lowering passengers or goods constructed and arranged in accordance
with my improvements; Figures 3 and 4 are horizontal sections taken on
the lines C, D, and E, F, of Figure 1. a, a, are arms, by preference fixed

page_text: the cage or room 6 may be raised and lowered by steam or other mecha-
nical means. The arms a, a, pass between the fixed guides c, c, into the
vertical grooves or channels c¹, c¹, formed on each side of the shaft of the
"lift." Chains a¹, a', are attached to the arms a, a, such chains passing
upwards over the pulleys a, a, their other ends being attached to balance
weights a³, which move up and down in the well a', formed on one side of
the shaft as shown; d, d, are friction rollers mounted on arms or brackets
fixed on the upper and under sides of the lifting cage or room b. These
friction rollers d are by preference formed with bevelled edges, so as to
travel up and down between the corresponding bevelled edges of the fixed
guides c, c, in order that they may at all times act correctly in their guides
should the lift move sideways in either direction. Figure 5 shows an iso-
metrical perspective view of a "lift" of similar construction, arranged with
two sets of balance weights a³, a³, moving up and down in separate wells
a, a, (in place of in one well as previously described,) for the purpose of
convenience. It will thus be seen that by means of the arrangements of
hydraulic and other "lifts" previously described all overhead gear is
dispensed with, and the consequent risk of injury from the falling of the
chain through the roof of the cage or room in case of accident is
avoided.
Having thus described the nature of my improvements, and the manner
of carrying the same into practice, I would remark that I do not confine
myself to the exact details herein described so long as the peculiar character
of my Invention is retained; but what I claim is the arrangement and
construction of hydraulic, steam, or other lifts for raising passengers
or goods whereby all overhead gear is dispensed with, as herein
described.
In witness whereof, I, the said James Norris, have hereunto set
my hand and seal, this Ninth day of May, in the year of our
Lord One thousand eight hundred and sixty-six..
