IMPROVEMENTS IN APPARATUS POR RAISING BUILDING MATERIALS
Year: 1860

page_text: LETTERS PATENT to Nathan Ager, of 77, Upper Ebury Street, Pimlico,
S.W., for the Invention of "IMPROVEMENTS IN APPARATUS POR RAISING
BUILDING MATERIALS."
Sealed the 7th May 1861, and dated the 28th November 1860.
PROVISIONAL SPECIFICATION left by the said Nathan Ager at the
Office of the Commissioners of Patents, with his Petition, on the 28th
November 1860.
I, NATHAN AGER, of 77, Upper Ebury Street, Pimlico, S.W., do hereby
declare the nature of the Invention for "IMPROVEMENTS IN APPARATUS FOR
RAISING BUILDING MATERIALS," to be as follows:-
This Invention has for its object improvements in apparatus for raising
building materials. For these purposes endless chains are used, which are
constructed in the following manner:-Two sets of short plates or links are
used, which are connected together at their ends by short rods, the ends of
which are passed through the ends of the side plates or links, by which the
side plates or links are made up into two parallel chains which are kept apart
by the rods. The rods are formed with small shoulders at each of their ends,
which come against the parallel side chains, and keep such chains at an equal
distance apart from each other. The ends of the rods are fixed by rivetting,
or by screws and nuts outside the parallel chains. Provision is made for
readily introducing or removing parts of the chains and rods in order to
accommodate the length of the endless chains to the height to which building

page_text: materials are for the time being to be lifted. The endless chains work with
an axis, having fixed thereon two discs or wheels, or it may be a single barrel
with notches or grooves thereon corresponding with the horizontal rods which
connect the two chains together; the horizontal rods are received into such
notches or grooves, whilst the links of the parallel chains are outside of such
discs or barrel. The axis receives motion by means of a crank handle on an
axis, having thereon a fly wheel, there being a pinion on such axis, which
gives motion to a cog wheel fixed on the axis carrying the discs or barrel. In
using this combined apparatus, hods, each with two hooks, are used, which
are hooked on to the horizontal rods of the parallel chains, or other forms
of holders suitable for carrying up the building materials may be hooked
on to the rods of the chains.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Nathan Ager in the Great Seal Patent Office on the
28th May 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NATHAN
AGER, of 77, Upper Ebury Street, Pimlico, S.W., send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of November, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Nathan Ager, Her special licence that I, the said Nathan Ager, my
executors, administrators, and assigns, or such others as I, the said Nathan
Ager, 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
APPARATUS FOR RAISING BUILDING MATERIALS," upon the condition (amongst
others) that I, the said Nathan Ager, 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.

page_text: NOW KNOW YE, that I, the said Nathan Ager, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, 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 apparatus for raising
building materials. For these purposes endless chains are used, which are
constructed in the following manner:-Two sets of short plates or links are
used, which are connected together at their ends by short rods, the ends of.
which are passed through the ends of the side plates or links, by which the
side plates or links are made up into two parallel chains, which are kept apart
by the rods. The rods are formed with small shoulders at each of their ends,
which come against the parallel side chains, and keep such chains at an equal
distance apart from each other. The ends of the rods are fixed by rivetting,
or by screws and nuts outside the parallel chains. Provision is made for
readily introducing or removing parts of the chains and rods, in order to
accommodate the length of the endless chains to the height to which building
materials are for the time being to be lifted. The endless chains work with
an axis, having fixed thereon two discs or wheels, or it may be a single barrel
with notches or grooves therein corresponding with the horizontal rods which
connect the two chains together; the horizontal rods are received into such
notches or grooves, whilst the links of the parallel chains are outside of such
discs or barrel. The axis receives motion by means of a crank handle on an
axis, having thereon a fly wheel, there being a pinion on such axis which gives
motion to a cog wheel fixed on the axis carrying the discs or barrel. In using
this combined apparatus, hods each with two hooks are used, which are hooked
on to the horizontal rods of the parallel chains, or other forms of holders
suitable for carrying up the building materials may be hooked on to the rods
of the chains.
And in order that my said Invention may be most fully understood and
readily carried into effect, I will proceed to describe the Drawings hereunto
annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a perspective view of the whole of the apparatus arranged in
the manner I prefer.
a, a, is a scaffolding supporting at the required height from the ground a
platform b. On this platform a frame c carrying an axis d is mounted, and on
this axis is a pinion gearing with a spur wheel e; the axis d has a handle
11

page_text: wheel e two metal discs f, f, are fixed; the form of these discs is clearly shewn
at Figure 2, which is a side view of a portion of the apparatus on a larger
scale. On the ground underneath the platform 6 is another frame g carrying
an axis, which also has fixed on it two discs h, h, similar to the discs f; the
lower axis with its discs h, h, is not, however, usually driven, but it may be so.
The double endless chain passing over the discs f, f, and h, h, at the top and
bottom of the scaffolding is marked i. The details of this chain are so fully
shewn at Figures 3, that no description of them beyond that already given will
be necessary; the manner in which the chain packs for carriage is shewn at
Figure 4. At the hooks applied to the side of the hods are clearly shewn.
In witness whereof, I, the said Nathan Ager, have hereunto set my
hand and seal, this Twenty-seventh day of May, in the year of
our Lord One thousand eight hundred and sixty-one.
NATHAN AGER. (L.S.)
