page_text: LETTERS PATENT to George Lewis and Alfred Lewis, both of Albert
Works, Kettering, in the County of Northampton, Engincers, for
the Invention of "IMPROVEMENTS IN TRUCKS OR BARROWS MORE ESPECIALLY
INTENDED FOR CARRYING, ELEVATING, EMPTYING, AND FILLING SACKS, LOADING
THEM INTO WAGGONS OR CARTS OR OTHER VEHICLES, AND OTHER LIKE
OPERATIONS."
ealed the 14th April 1874, and dated the 20th January 1874. .
PROVISIONAL SPECIFICATION left by the said George Lewis and
Alfred Lewis at the Office of the Commissioners of Patents, with
their Petition, on the 20th January 1874.
We, GEORGE LEWIS and ALFRED LEWIS, both of Albert Works,
Kettering, in the County of Northampton, Engineers, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN TRUCKS OR
BARROWS MORE ESPECIALLY INTENDED FOR CARRYING, ELEVATING, EMPTYING, AND
FILLING SACKS, LOADING THEM INTO WAGGONS OR CARTS OR OTHER VEHICLES, AND
OTHER LIKE OPERATIONS," to be as follows:-
:-
The improvements embrace a sack elevator, sack shooter, sack holder,
and loader, and will be understood from the objects or purposes to be

page_text: attained, which are these:-A sack (say of corn) may be placed on the
improved truck or barrow, may be lifted or raised in an inclined or
vertical line of movement, may conveniently be tilted over by an
attendant and the contents transferred to another sack supported and
held open by the sack holder at the back of the elevator, or instead of
transferring the contents the bottom or lower end of the sack may be
mechanically tilted by raising the tail or lower end, so as to tilt or
further tilt or turn the sack into an inverted position.
We construct the improved barrows with two winch motions, one per-
forming the elevating operation much the same as heretofore, the other
performing the tilting or further tilting operation, and with a suspending
frame for holding open the mouth of a sack. This frame being some-
times so made or hinged or applied to the barrow as to fold or pack away
into smaller compass when desired. The back of the elevator is made
with an opening, through, over, or across which the sack may be tilted.
The clevator and tilter both slide in grooves, or are otherwise con-
veniently guided in or on the frame of the barrow. The windlasses
have (sometimes) chains or cords for working the elevator and tilter,
and palls and ratchets to prevent. these from unintentionally running
down till released. The barrow is mounted on wheels, as usual. The
sack holder, apart from combination, is not new, nor the sack elevator,
apart from combination, excepting in respect of the opening at the back
thereof, through, over, or across which the sack may be tilted. With
these exceptions all separate, and all and any convenient combined con-
structions and uses of the elevator, tilter, and holder are intended.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Lewis and Alfred Lewis in the Great Seal
Patent Office on the 20th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
LEWIS and ALFRED LEWIS, both of Albert Works, Kettering, in the 3
County of Northampton, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of January, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-

page_text: seventh year of Her reign, did, for Herself, Hér heirs and successors,
give and grant unto us, the said George Lewis and Alfred Lewis, Her
special licence that we, the said George Lewis and Alfred Lewis,
executors, administrators, and assigns, or such others as we, the said
George Lewis and Alfred Lewis, our 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 tho
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN TRUCKS OR BARROWS
MORE ESPECIALLY INTENDED FOR CARRYING, ELEVATING, EMPTYING, AND FILLING
SACKS, LOADING THEM INTO WAGGONS OR CARTS OR OTHER VEHICLES, AND OTHER
LIKE OPERATIONS," upon the condition (amongst others) that we, the
said George Lewis and Alfred Lewis, our executors or administrators,
by an instrument in writing under our, 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 we, the said George Lewis and Alfred Lewis,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
:-
The improvements embrace a sack elevator, sack shooter or holder,
and sack tilter or loader, and will be understood from the objects or
purposes to be attained, which are these. A sack (say of corn) may bo
placed on the improved truck or barrow, may be lifted or raised in an
inclined or vertical line of movement, may conveniently be tilted over
by an attendant and the contents transferred to another sack, supported
and held open by the sack shooter or holder at the back of the elevator,
or instead of transferring the contents the bottom or lower end of the
sack may be mechanically tilted by raising the tail or lower end, so as
to tilt or further tilt or turn the sack into an inverted position.
We construct the improved barrows with two winch motions, one per-
forming the clevating operation, much the same as heretofore, the other
performing the tilting or further tilting operation, and with a suspending

page_text: frame or shooter for holding open the mouth of a sack for receiving the
contents of or from another sack. This frame being sometimes so made
or hinged or applied to the barrow as to fold or pack away into smaller
compass when desired. The back of the elevator is made with an opening,
through, over, or across which the sack may be tilted or upset for this
purpose. The elevator and tilter both slide in grooves, or are otherwise
conveniently guided in or on the frame of the barrow. The windlasses
have (sometimes) chains or cords for working the elevator and tilter, and
palls and ratchets to prevent these from unintentionally running down
till released. The barrow is mounted on wheels as usual.
In the accompanying illustrative Drawing Figure 1 is a perspective
view of a truck or barrow constructed in accordance with and embracing
the several features of the Invention.
Figure 2 is a sectional elevation or side view, showing the apparatus
as in use for shooting from one sack into another, the position of the
sacks being shown in faint lines.
a, a, are two main side frames, partly of wood and partly of metal,
connected together by an ordinary foot or bow iron b at the bottom, and
by one or more iron cross frames or bars c (one only being represented).
On the inner side of each of the frames a are two longitudinal-grooves a*,
as seen in the section Figure 3; d, d*, is the elevator, of which
separately a front clevation and plan aro represented in the Figures 4*
and 4 respectively. It consists, as represented, of iron bars forming a
sack rest or platform with upright side or guide bars for working in
the front pair of grooves a*, and with cross framing; and it is specially
to be noted that its cross bar or frame, marked d*, is curved or bowed
downwards and not carried straight across. The clevator is capable
of sliding up and down in its proper grooves a*, and is furnished
with lifting chains e extending to the upper and front winding bar,
barrel, or winch f, by means of which it may be elevated to any desired
extent and retained at any desired height by a catch or pall acting on a
ratchet wheel; g is the sack shooter, holder, or suspender (shewn
detached at Figures 5^ and 5³), constructed of iron and hinged to the
frames a, and provided with hooks and spikes for holding open the
mouth of a sack into which a full one is desired to be emptied; g* is a
part of the holder, fixed at an angle as a guiding frame for directing the
mouth of the sack to be emptied. When in use the frame g is held up

page_text: by chains horizontally, or at any desired degree of inclination, as
shewn in Figures 1 and 2, and when these aro released the frame may
be dropped, as shewn in Figure 5, or if desired may be unhinged or
removed from the barrow. This Figure (5) is a diagram or partial
section, corresponding generally with Figure 2, but shewing some of the
parts in a different position; the apparatus being represented as in use
for loading sacks into a cart or turning them over (mouth downwards)
or into an inverted position on to a floor or platform (z), which within
certain limits may be at any height, the apparatus admitting of its.
members being adjusted or worked accordingly; i, i*, is what we term
the tilter or loader, of which separately a plan, a front elevation, and a
transverse section, are represented in the Figures 6**, 6*, and 6,
respectively. This consists, as represented, of an iron framing with
upright side or guide bars for working in the back pair of grooves a* of
the main side frames of the apparatus, and with cross framing; and it
is specially to be noted that its top cross bar ** is intended to bear
against the under side of a sack after it has been thrown down or across
the curved bar d* of the elevator, and again to raise or tilt, or to further
raise or tilt; one end of the sack and turn it over or upset it, whereby
it becomes the means of loading into a waggon or on to a platform, as
shown in the Figure 5. With this object the sack in being thrown down
should be placed over or across the bar i* somewhat beyond the middle
of its length. By performing the operations in a reverse order it is
evident that sacks may be unloaded and lowered instead of raised and
loaded as above described. The tilter is capable of sliding up and down
in its proper grooves a*, and is furnished with lifting chains / extending
to the lower and back winding bar, barrel, or winch 1, by means of
which it may be elevated as required and retained at any desired height
by a catch or pall acting on a ratchet wheel.
Figure 7 is a perspective view, corresponding generally with Figure 1,
but shewing the main frames only of the apparatus, without the elevator,
the shooter, the tilter, and other parts.
Having now described the nature of our said Invention, and the
manner in which the same is to be and may be performed, we claim as
of our said Invention the constructing the sack elevator with a curved
cross bar or frame, as described.
Also we claim the sack tilter or loader.

page_text: Also the combination of a sack elevator and sack shooter or holder
with or upon a barrow or truck.
Also the combination of a sack elevator and sack tilter or loader with
or upon a barrow or truck, and with or without a sack shooter or
holder.
. And also the construction of a barrow or frame for the purposes of the
Invention, with two sets of sliding grooves, in which the elevator and
tilter may respectively work.
And, Lastly. We claim the construction of the apparatus with two
winches in combination with other parts for the purposes of the In-
vention, as described.
In witness whereof, we, the said George Lewis and Alfred Lewis,
have hereunto set our hands and seals, this Sixteenth day of
July, in the year of our Lord One thousand eight hundred and
seventy-four.
