Year: 1873

page_text: LETTERS PATENT to Henry Batt, of Victoria Road, Kentish Town,
in the County of Middlesex, Builder, for the Invention of “IM-
PROVEMENTS IN MACHINERY OR APPARATUS FOR HOISTING BUILDING AND
OTHER MATERIALS, OR FOR RAISING AND LOWERING HEAVY WEIGHTS.
PROVISIONAL SPECIFICATION left by the said Henry Batt at the
Office of the Commissioners of Patents, with his Petition, on the
23rd July 1873.
I, HENRY BATT, of Victoria Road, Kentish Town, in the County of
Middlesex, Builder, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR HOISTING BUILDING AND
OTHER MATERIALS, OR FOR RAISING AND LOWERING HEAVY WEIGHTS," to be as
follows:-
This Invention relates to improvements in machinery or apparatus in
which a treble action reversible up-and-down motion hoist is arranged
suitable for raising and lowering building or any other description of
materials either light or heavy, being so constructed as to hoist and

page_text: lower four barrows at the same time, or two barrows and any heavy
materials, such as stone, or timber, or iron,, without in the slightest
degree interfering with each other while at work, the working action
being quite separate and actuated either by steam or hand power.
The apparatus consists of three drums, two at top and one at the
bottom of the hoist, each drum being divided into two parts. Two-
spindles are arranged over the two top drums, and upon one end of each
of these spindles three riggers are mounted, one fixed and two loose, also
a small cog wheel working into a larger one, which larger one is fixed
upon another spindle upon which the drum is fixed, the lower drum
being actuated by one of the top ones which has cog wheels to increase
the power. The two top drums are for raising light materials, and the
lower one for heavy materials. The lower drum is constructed to work
back the chain or rope after the material is hoisted.
The apparatus is so constructed as to be thrown in and out of gear
and to hold the material at any height.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Batt in the Great Seal Patent Office on
the 23rd January 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BATT, of Victoria Road, Kentish Town, in the County of Middlesex,
Builder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of July in the year of
`our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Batt, Her special license
that I, the said Henry Batt, my executors, administrators, and
assigns, or such others as I, the said Henry Batt, 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

page_text: MACHINERY OR APPARATUS FOR HOISTING BUILDING AND OTHER MATERIALS, OR FOR
RAISING AND LOWERING HEAVY WEIGHTS," upon the condition (amongst
others) that I, the said Henry Batt, 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 Henry Batt, 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 improvements in machinery or apparátus in
which a treble action reversible up-and-down motion hoist is arranged
suitable for raising and lowering building or any other description of
materials either light or heavy, being so constructed as to hoist and
lower four barrows or weights at the same time, or two barrows and any
other heavy materials, such as stone, timber, or iron, without in the
slightest degree interfering with each other while at work, the working
action being quite separate and actuated either by steam or hand
power.
The apparatus consists of three drums a, b, c, arranged as shown in
the Drawing hereunto annexed, the two marked a, b, mounted in
bearings at the top; and the one marked c at the bottom of the framing.
of the hoist apparatus, each drum being divided into two parts by a
flange a¹, 61, as shewn. On one division of each drum a and b a chain
or rope is wound up, another chain or rope being at the same time
unwound from the other division, one end of each chain or rope being
connected to the drum, the other end passing over a pulley or pulleys to
the weight to be raised or lowered. Two spindles e, f, are arranged over
the two top drums a, b, and upon one end of each of these spindles e, f,
three riggers e¹; f¹, are mounted (one fixed and two loose), also small
cog wheels or pinions e³, f³, working into spur wheels a³, b², fixed upon
the axes upon which the drums a, b, are fixed. The lower drum c is
actuated by a pinion a³ fixed on the axis of the top drum a taking into
the large cog wheel e³ fixed on the axis of the drum c to increase its

page_text: power. The two top drums a, b, are employed for raising light materials,
and the lower one c for raising heavy materials. The lower drum c is
constructed to work back the chain or rope after the material is hoisted
by means of a cord attached at one end to the drum c, and the other
end to the hoisting hook or link, the reverse motion of the drum acting
by means of the cord to wind back the hoisting chain.
.
The apparatus is so constructed as to be thrown in and out of gear by
sliding forks e³, f³, for shifting the driving belts from the fast to the
loose pulleys, and to hold the material or weight at any height required
by means of the levers and breaks g, h, which act on the circumference
of the spur wheels a³, b². When the drum c is in operation for raising
a weight, the chain on the drum a is disengaged. The two upper
drums a, b, can be used independently of the lower drum c by disen-
gaging the rope or chain on the drum.c.
Having thus described the nature of my Invention, and the manner of
performing or carrying the same into practice, I would have it under-
stood that I do not confine myself to the exact details herein described
so long as the main features of my Invention are retained, but what I
claim is, the improved arrangement and combination of machinery or
apparatus for hoisting building and other materials, or for raising and
lowering heavy weights, in which the drums or barrels a, b, and c are
combined and arranged to act, substantially in the manner and for the
purposes herein-before described and shown in the Drawings hereunto
annexed.
In witness whereof, I, the said Henry Batt, have hereunto set
my hand and seal, this Twenty-second day of January, in the year
of our Lord One thousand eight hundred and seventy-four.
