PROVISIONAL SPECIFICATION left by the said George Tomlinson
Bousfield at the Office of the Commissioners of Patents, with his
Petition, on the 5th August 1875.
I, GEORGE TOMLINSON BOUSFIELD, of Sutton, in the County of Surrey,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN POWER LOOMS FOR WEAVING PILED FABRICS," to be as follows:-
This Invention relates to the mechanism for operating the pile wires,
and is illustrated by the accompanying Drawings.
Figure 1 is a front elevation of the improved mechanism and such
other parts of a loom as are necessary to illustrate its construction and

page_text: operation; Figure 2 is a right-hand elevation of the same'; Figure 3, a
rear elevation; and Figure 4, a plan.
The object of the Invention is to simplify the construction of the
mechanism, and to facilitate the passage of the pile wires into the shed
of the warps.
A part of the Invention consists in the employment of two oscillating
staffs to operate the pile wires, one to carry the withdrawing hook and
the other the inserting receiver or its equivalent, and also in the mode
of constructing and operating said staffs.
In order that the pile wires may pass properly into the shed of the
warps it is necessary that their inner ends should be directed towards its
deepest part whilst being inserted, and then swung towards the cloth-
forming line as the inserting operation is being completed.
Heretofore the inserting receiver or its equivalent has had but two
movements, one towards and from the lay and another towards and from
the cloth, the direction of the latter movement being sometimes inclined
slightly towards the reed. I find in practice that by giving it an addi-
tional movement irrespective of the direction of its other movements a
better result is obtained. Another part of the Invention, therefore,
consists in giving to the inserting receiver or its equivalent an oscil-
lating movement in addition to its two usual movements, whereby any
desired lateral movement may be given to the inner ends of the pile
wires whilst they are being inserted, whatever may be the direction in
which said inserting receiver- or its equivalent may be moved towards
the cloth. This part of the Invention is applicable and it is intended
to apply it to inserting receivers or their equivalents carried by slides
and slide bars, as well as to those carried by oscillating staffs.
The frame of the loom to which the improved wire operating
mechanism is applied is indicated in the Drawings by a, the cloth
by b, the ground warp by c, the figure warp by d, the shed for the
passage of the shuttle by c, and the shed for the reception of the pile
wires by f, the two sheds being represented in the position given them.
at the time a pile wire is inserted and the shuttle thrown.
The pile wires are formed with heads, as is usual, and as shown in
Figure 5. A series of them as they are held in position by the guard

page_text: .
and lie in the cloth during the operation of weaving is represented in
Figure 4.
The improved mechanism which acts in succession on the forward one
of the series will now be described. It is actuated by a shaft i, which
receives motion from the cam shaft ; through the action of the bevil
gears. The shaft is supported by two stands and m, which are
held together by a girth n. The withdrawing staff, which at its upper
end carries the withdrawing hook, is held in position by a stand o, and
oscillates on a stud p affixed thereto. Now it will be obvious that if
the distance between the upper end of the staff and the stud p remains
constant the withdrawing hook as the staff oscillates towards and from
the cloth would move in an are of a circle corresponding to the radius
thus formed, whereas it is necessary that it should move more nearly in
a horizontal plane. To effect this result the staff is made in two parts,
which are respectively indicated by q and r. The upper part q is con-
nected with the lower part in such manner as to be capable of moving
up and down in the guide bearings s (see Figure 6), and to sustain it
in its proper vertical position and to cause its upper end to move
towards and from the cloth in the required horizontal plane a bar or
link is employed, the lower end of which is jointed to the part q,
whilst its upper end is supported by and oscillates on a stud u affixed to
the stand o, before mentioned, the several parts co-operating on the prin-
ciple of the well-known "parallel motion." The length of the bar or
link and the position of the axis on which it oscillates are so adjusted
with respect to each other as to cause the upper end of the oscillating
staff as it draws out a wire to rise above the plane of the wires in
the cloth and elevate the wire to the proper position to enter the
shed f
The withdrawing hook is formed on the rear side of a lever arm w,
which is jointed at a to an adjustable bar on the upper end of the part q
of the withdrawing staff. It is formed on the lever arm instead of the
end of the staff in order that by swinging the lever arm into a vertical
position the hook may be prevented from 'drawing out the pile wires
when the loom is turned to restore a "lost pick." A spring y holds
the lever arm when at rest in its vertical or horizontal position. The
withdrawing staff is moved towards and from the cloth by the shaft i
before mentioned, the motion being transmitted through the medium of
the disc, stud a', and connecting bar b', and when it has nearly com..

page_text: pleted its movement towards the cloth the hook engages the wire head,
as is usual, and when it moves from the cloth it draws out a wire and
delivers it to the inserting mechanism, which will now be described.
A front view of the inserting mechanism is represented in Figure 7
detached from the loom. The inserting staff is made in two parts which
are respectively designated c¹ and d'; the part c' is connected with the
part d'in such manner as to be capable of moving up and down freely
in the guide bearings e¹, and for the same purpose that the two parts of
the withdrawing staff before described are similarly connected. The
lower part d¹ is affixed to a horizontal axis f¹, which will hercin-after
be described. The upper part c' with which the inserting receiver or
its equivalent g¹ is connected is held in its vertical position, and caused
to move towards the cloth in a proper plane for inserting the pile wires
by a stud h¹ which carries a roller i¹, which traverses a slot j¹ formed in
the bar . By this arrangement it will be seen that the plane in
which the inserting receiver moves may be varied to any desired extent
by a corresponding variation of the slot j¹. Instead of the stud h',
roller, and slot j', for keeping the inserting receiver in the required
planc, a bar or link similar to that used in connection with the with-
drawing staff, as before described, is sometimes substituted.
The inserting receiver or its equivalent has three movements, one
towards and from the lay to successively receive the pile wires from the
withdrawing hook and carry them from the line where they are drawn
from the cloth to the line, where they are inserted in the shed of the warps,
another motion towards and from the cloth to insert them, and another
to direct their inner ends towards the reed or deepest part of the shed
whilst being inserted, and to swing them towards the cloth forming line
as thic inserting operation is being completed.
These movements are effected respectively as follows:-The mechanism
connected with the inserting receiver is supported by a frame consisting
of an axis, and a bow projection m³ on its rear side, as shown in Figure 4.
Two standards marked n' are affixed to the axis l', and support at their

by bearings o¹ and is capable of oscillating therein.
The axis before mentioned to which the lower part d' of the
inserting staff is affixed, is supported by bearings formed in the axis
and bow projection m', and is capable of oscillating therein. From this

page_text: description it will be readily seen that by oscillating the axis ¹ the
inserting receiver g' will be moved towards and from the lay, and that
by oscillating the axis fit will be moved towards and from the cloth.
To the rear end of the bow projection m¹ the lower end of a rod p' is
jointed whilst its upper end is jointed at q¹ to the inner end of a lever
arm which oscillates on a stud s¹. A cam l'on the shaft i acts on a
roller on the side of the lever arm r¹, and thus turns the axis and
moves the inserting receiver from the reed, whilst a spring
draws it
in the opposite direction when the cam allows it to do so. A bent
lever arm w¹ oscillates on a stud x¹, and is connected by a bar y' to the
lower part of the oscillating staff. A cam acts on a roller all on
the side of the lever arm w¹ and moves the inserting receiver towards
the cloth, whilst the coiled spring on the axis f¹ draws it in the opposite
direction, a grooved cam being sometimes employed which moves it in
both directions. The inserting receiver g¹ is formed on a spindle bu
which is capable of oscillating in bearings c" projecting from the front
side of the upper part c¹ of the inserting staff. Its socket which
receives the pile wire heads from the withdrawing hook is represented
by Figure 8 and Figure 9, Figure 9 being an enlarged front view, and
Figure 8 an edge view, showing its mouth, which is slightly bevilled to
facilitate the entrance of the wire heads. The mouth of the socket is
also made wider than its bottom, as indicated by the dotted lines in
Figure 9, in order that the wire heads may retain their horizontal position
whilst the angle of the staff is changed by its movement towards the
cloth. The front side piece of the socket is cut out at du for a passage
for the withdrawing hook as it draws in a wire head.
To prevent the wire heads from escaping unduly from the socket and
yet not hold them so firmly but that the socket can readily be with-
drawn without displacing the pile wires, a spring e" is affixed to the
rear side piece of the socket, on the upper end of which a convex
face is formed which passes through said rear side piece into the
path of the wire head. Now it will be obvious that as a wire head
is drawn into the socket the convex face of the spring will yield to
its pressure until the hole in the wire head on which it acts is brought
in range with it, when it will engage therewith and hold the pile wire
in position whilst being inserted, though not so firmly but that the
receiver as it returns for a succeeding wire is readily withdrawn
from it

page_text: The movement of the inserting receiver or its equivalent, whereby
the inner ends of the pile wires are directed towards the reed or deepest
part of the shed whilst they are being inserted therein and swung
towards the cloth forming line as the inserting operation is being
completed, is imparted to it as follows, videlicit :-The spindle on
which the inserting receiver is formed has a helical spring g" surrounding
it, which constantly tends to turn the mouth of the receiver towards
the reed, though its movement in that direction is limited by a fixed
stop.
To the lower end of the spindle 6" a bent lever arm " is affixed, the
depending arm of which at appropriate intervals acts on cam surfaces
and ju̟, which are affixed to the slotted bar, before described.
When the inserting receiver is at the outward stage of its movement, in
which it is represented in Figurec 7, its mouth is on the line on which
the pile wires are drawn from the cloth and delivered to it, then when the
receiver has started on its movemement towards the cloth to insert the
wire, the cam surface allows the spring g" to turn the spindle " to
the fixed stop before mentioned, and thus direct the inner end of the
wire towards the reed, in which relative position the receiver and the
wire continue their movement until the depending arm of the lever "
reaches the cam surface j" which turns the receiver back to its former
position, and swings the inner end of the wire towards the cloth forming
line as the inserting operation is being completed. A mode of effecting
these movements of the inserting receiver when it is carried by a slide,
and a slide bar is represented in Figure 10 and Figure 11. The slide
bar is traversed by the slide 1", as is usual, and the spindle 6" of the
inserting receiver g' oscillates in bearing c" projecting from the slide 2"
in the same manner as when it is carried by the oscillating staff just
described. In the side of the slide bar a recess m¹¹ is formed, the
bottom of which is shaped in accordance with the oscillating movement
required to be given to the receiver. The lever arm " carrics a
roller which rests on the bottom of the recess m". The helical
spring on the spindle constantly tends to press the roller against
the bottom of the recess, so that as the receiver is moved towards the
cloth to insert a wire it oscillates in accordance with the form of thic
bottom of the recess. The inner ends of the pile wires are transferred
from the line where they are drawn from the cloth to the point where
they are inserted by a carrier o" as is usual. It starts on its movement
11

page_text: towards the lay in unison with the inserting receiver which carries the
outer end of the pile wires, though it moves a greater distance than the
inserting receiver, thus deflecting the pile wires to the point of insertion
as is usual. The carrier o" oscillates on a stud ", and is affixed to a
horizontal arm q" which is connected by a bar to a lever arms" which
oscillates on the studs, and is actuated by a cam t" on the shaft i. But
as this part of the mechanism forms no part of my Invention a further
description of it is deemed unnecessary.
The withdrawing hook and the inserting receiver co-operating with-
draw and insert a pile wire at every two beats of the lay. When the
former has engaged a wire and nearly completed its movement from the
cloth the latter takes a position by its side, and by pressing against a
guide bar on the withdrawing staff the two parts are kept in such
relation to each other that the hook moving a little faster than the
receiver draws the wire head into the socket of the receiver; thus armed
with a wire it moves back towards the lay to the line of insertion, then
towards the cloth, and inserts the wire as herein-before explained.

of Man, an Invention for "IMPROVEMENTS IN POWER LOOMS FOR WEAVING
PILED FABRICS," a communication to me from abroad by Erastus Brigham
Bigelow, of Boston, in the County of Suffolk, and State of Massachusetts,
in the United States of America, upon the condition (amongst others)
that I, the said George Tomlinson Bousfield, my executors or admini-
strators, by an instrument in writing under my, or their, or one of
their hands and scals, should particularly describe and asscertain 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 Scal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Tomlinson Bousfield, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, that is to say :—
This Invention relates to the mechanism for operating the pile wires,
and is illustrated by the accompanying Drawings.
Figure 1 is a front elevation of the improved mechanism and such
other parts of a loom as are necessary to illustrate its construction and
operation; Figure 2 is a right-hand elevation of the same; Figure 3, a
rear elevation; and Figure 4, a plan.
The object of the Invention is to simplify the construction of the
mechanism and to facilitate the passage of the pile wires into the shed
of the warps.
A part of the Invention consists in the employment of two oscillating
staffs to operate the pile wires, one to carry the withdrawing hook, and
the other the inserting receiver or its equivalent; and also in the mode
of constructing and operating said staffs.
In order that the pile wires may pass properly into the shed of the
warps it is necessary that their inner ends should be directed towards its
deepest part whilst being inserted, and then swung towards the cloth,
forming line as the inserting operation is being completed.
Heretofore the inserting receiver or its equivalent has had but two
movements, one towards and from the lay, and another towards and

page_text: L
from the cloth, the direction of the latter movement being sometimes
inclined slightly towards the reed. I find in practice that by giving it
an additional movement, irrespective of the direction of its other move-
ments, a better result is obtained. Another part of the Invention
therefore consists in giving to the inserting receiver or its equivalent an
oscillating movement in addition to its two usual movements, whereby
any desired lateral movement may be given to the inner ends of the pile
wires whilst they are being inserted, whatever may be the direction in
which said inserting receiver or its equivalent may be moved towards
the cloth. This part of the Invention is applicable and it is intended to
apply it to inserting receivers or their equivalents carried by slides and
slide bars, as well as to those carried by oscillating staffs.
The frame of the loom to which the improved wire operating
mechanism is applied is indicated in the Drawings by a, the cloth by b,
the ground warp by c, the figure warp by d, the shed for the passage of
the shuttle by e, and the shed for the reception of the pile wires by f,
the two sheds being represented in the position given them at the time
a pile wire is inserted and the shuttle thrown.
The pile wires g are formed with heads, as is usual, and as shown in
Figure 5. A series of them, as they are held in position by the guard
and lic in the cloth during the operation of weaving, is represented in
Figure 4.
The improved mechanism which acts in succession on the forward one
of the series will now be described. It is actuated by a shaft i, which
receives motion from the cam shaft j through the action of the bevil
gears .
The shaft is supported by two stands and m, which are held
together by a girth n. The withdrawing staff, which at its upper end
carries the withdrawing hook, is held in position by a stand o, and
oscillates on a stud p affixed thereto. Now it will be obvious that if the
remains
distance between the upper end of the staff and the stud
constant, the withdrawing hook, as the staff oscillates towards and from
the cloth would move in an arc of a circle corresponding to the radius
thus formed, whereas it is necessary that it should move more nearly in
a horizontal plane. To effect this result the staff is made in two parts,
which are respectively indicated by 9 and 7. The upper part q is con-
g
nected with the lower part in such manner as to be capable of moving
up and down in the guide bearings & (see Figure 6), and to sustain it in

page_text: its proper vertical position; and to cause its upper end to move towards
and from the cloth in the required horizontal plane a bar or link is
employed, the lower end of which is jointed to the part q, whilst its
upper end is supported by and oscillates on a stud u affixed to the
stand o, before mentioned,, the several parts co-operating on the principle
of the well-known "parallel motion." The length of the bar or link t
and the position of the axis on which it oscillates are so adjusted with
respect to each other as to cause the upper end of the oscillating staff as
it draws out a wire to rise above the plane of the wires in the cloth, and
elevate the wire to the proper position to enter the shed f.
The withdrawing hook is formed on the rear side of a lever arm w,
which is jointed at a to an adjustable bar on the upper end of the part q
of the withdrawing staff. It is formed on the lever arm instead of the
end of the staff in order that by swinging the lever arm into a vertical
position the hook may be prevented from drawing out the pile wires
when the loom is turned to restore a "lost pick;" a spring y holds the
lever arm when at rest in its vertical or horizontal position. The with-
drawing staff is moved towards and from the cloth by the shaft i before
mentioned, the motion being transmitted through the medium of the disc,
stud a', and connecting bar b', and when it has nearly completed its move-
ment towards the cloth the hook engages the wire head as is usual, and
when it moves from the cloth it draws out a wire and delivers it to
the inserting mechanism, which will now be described.
A front view of the inserting mechanism is represented in Figure 7
detached from the loom. The inserting staff is made in two parts, which
are respectively designated c¹ and d¹. The part c¹ is connected with the
part in such manner as to be capable of moving up and down
freely in the guide bearings e¹, and for the same purpose that the two
parts of the withdrawing staff before described are similarly connected.
The lower part d' is affixed to a horizontal axis f¹, which will hercin-
after be described. The upper part c', with which the inserting receiver
or its equivalent ¹ is connected, is held in its vertical position and
caused to move towards the cloth in a proper planc for inserting the
pile wires by a stud h', which carries a roller which traverses a slot j¹
formed in the bar . By this arrangement it will be seen that the
plane in which the inserting receiver moves may be varied to any
desired extent by a corresponding variation of the slot. Instead of the
stud ¹, roller ', and slot j¹ for keeping the inserting receiver in the

page_text: required plane a bar or link similar to that used in connection with
the withdrawing staff, as before described, is sometimes substituted.
The inserting receiver or its equivalent has three movements, ono
towards and from the lay to successively receive the pile wires from the
withdrawing hook and carry them from the line where they are drawn
from the cloth to the line, where they are inserted in the sled of the
warps; another motion towards and from the cloth to insert them; and
another to direct their inner ends towards the reed or deepest part of
the shed whilst being inserted, and to swing them towards the cloth
forming line as the inserting operation is being completed.
These movements are effected respectively as follows:-The mechanism
connected with the inserting receiver is supported by a frame consisting
of an axis and a bow projection m' on its rear side, as shown in
Figure 4. Two standards marked n are affixed to the axis and
support at their upper ends the slotted bar before described.
axis is supported by bearings o¹ and is capable of oscillating therein.
The
The axis before mentioned to which the lower part d' of the
inserting staff is affixed is supported by bearings formed in the axis and
bow projection m³, and is capable of oscillating therein. From this
description it will be readily seen that by oscillating the axis the
inserting receiver g¹ will be moved towards and from the lay, and that by
oscillating the axis f¹ it will be moved towards and from the cloth. To the
rear end of the bow projection m¹ the lower end of a rod p' is jointed,
whilst its upper end is jointed at q¹ to the inner end of a lever arm ¹,
which oscillates on a stud s'. A cam on the shaft i acts on a roller u¹
on the side of the lever arm, and thus turns the axis and moves the
inserting receiver from the reed, whilst a spring ' draws it in the opposite
direction when the cam t allows it to do so. A bent lever arm w' oscil-
lates on a stud x', and is connected by a bar y to the lower part d' of
the oscillating staff. A cam acts on a roller a" on the side of the lever
arm and moves the inserting receiver towards the cloth, whilst the
coiled spring on the axis f¹ draws it in the opposite direction, a grooved
cam being sometimes employed which moves it in both directions.
inserting receiver g¹ is formed on a spindle 6", which is capable of
oscillating in bearings c" projecting from the front side of the upper
part of the inserting staff; its socket which receives the pile wire
heads from the withdrawing hook is represented by Figure S and
The

page_text: Figure 9, Figure 9 being an enlarged front view and Figure 8 an edge
view, showing its mouth, which is slightly bevilled to facilitate the
entrance of the wire heads. The mouth of the socket is also made wider
than its bottom, as indicated by the dotted lines in Figure 9, in order
that the wire heads may retain their horizontal position, whilst the angle
of the staff is changed by its movement towards the cloth. The front
side piece of the socket is cut out at " for a passage for the withdrawing
hook as it draws in a wire head.
To prevent the wire heads from escaping unduly from the socket and
yet not hold them so firmly but that the socket can readily be
withdrawn without displacing the pile wires, a spring e" is affixed to the
rear side picce of the socket, on the upper end of which a convex
face is formed, which passes through said rear side piece into the
path of the wire head. Now it will be obvious that as a wire head
is drawn into the socket the convex face of the spring will yield
to its pressure until the hole in the wire head on which it acts is
brought in range with it, when it will engage therewith and hold the
pile wire in position whilst being inserted, though not so firmly
but that the receiver as it returns for a succeeding wire is readily
withdrawn from it.
The movement of the inserting receiver, or its equivalent, whereby
the inner ends of the pile wires are directed towards the reed or deepest
part of the shed whilst they are being inserted therein, and swung
towards the cloth forming line as the inserting operation is being
completed is imparted to it. as follows, viz., the spindle & on which
the inserting receiver is formed has a helical spring g" surrounding it,
which constantly tends to turn the mouth of the receiver towards
the reed, though its movement in that direction is limited by a fixed
stop.
To the lower end of the spindle a bent lever arm " is affixed, the
depending arm of which at appropriate intervals acts on cam surfaces ¿"
and j", which are affixed to the slotted bar ³, before described; when the
inserting receiver is at the outward stage of its movement, in which it
is represented in Figure 7, its mouth is on the line on which the pile
wires are drawn from the cloth and delivered to it, then when the
receiver has started on its movement towards the cloth to insert the
wire the cam surface allows the spring 7" to turn the spindle 6" to

page_text: 12
the fixed stop before mentioned, and thus direct the inner end of the
wire towards the reed, in which relative position the receiver and the
wire continue their movement until the depending arm of the lever h"
reaches the cam surface j", which turns the receiver back to its former
position and swings the inner end of the wire towards the cloth forming
line as the inserting operation is being completed. A mode of effecting
these movements of the inserting receiver when it is carried by a slide
and a slide bar is represented in Figure 10 and Figure 11. The slide
bar is traversed by the slide 1" as is usual, and the spindle 6" of the
inserting receiver g¹ oscillates in bearing c", projecting from the slido ¹¹
in the same manner as when it is carried by the oscillating staff just
described. In the side of the slide bar a recess m is formed, the
bottom of which is shaped in accordance with the oscillating movement
required to be given to the receiver. The lever arm " carries a roller "1
which rests on the bottom of the recess m¹¹. The helical spring g" on
the spindle constantly tends to press the roller against the bottom of
the recess, so that as the receiver is moved towards the cloth to insert
a wire it oscillates in accordance with the form of the bottom of the
The inner ends of the pile wires are transferred from the line
where they are drawn from the cloth to the point where they are inserted
by a carrier o¹¹ as is usual. It starts on its movement towards tho lay
in unison with the inserting receiver which carries the outer end of the
pile wires, though it moves a greater distance than the inserting receiver,
thus deflecting the pile wires to the point of insertion as is usual. The
carrier o oscillates on a stud p", and is affixed to a horizontal arm q",
which is connected by a bar to a lever arm s¹ which oscillates on
the stud & and is actuated by a cam " on the shaft i. But as this part
of the mechanism forms no part of the Invention a further description
of it is deemed unnecessary.
recess.
The withdrawing hook and the inserting receiver, co-operating, with-
draw and insert a pile wire at every two beats of the lay. When the
former has engaged a wire and nearly completed its movement from the
cloth, the latter takes a position by its side, and by pressing against a
guide bar on the withdrawing staff the two parts are kept in such
3 relation to cach other that the hook moving a little faster than the
receiver draws the wire head into the socket of the receiver; thus armed
with a wire it moves back towards the lay to the line of insertion, then
towards the cloth, and inserts the wire as herein-before explained.

page_text: It will be obvious to those accustomed to construct machinery that
the form and arrangement of many of the parts above described may be
varied without departing from the principles of this Invention. I am
aware that an oscillating staff has been used to carry the inserting
receiver, or its equivalent in combination with the slide traversing a
slide bar to carry the withdrawing hook, and also that a single oscillating
staff has been employed to carry both the withdrawing hook and the
inserting receiver, but the employment of two oscillating staffs as herein
set forth I believe to be new.
What I claim as new and desire to secure by Letters Patent is the
combination of two oscillating staffs, constructed and operated sub-
stantially as herein described, when one of said staffs is employed to
draw the pile wires from the cloth and the other to insert them in the
shed of the warps, substantially as specified.
I also claim giving to the inserting receiver or its equivalent an
oscillating movement towards and from the lay in addition to its usual
movements, and irrespective of the direction of its movement towards
and from the cloth, substantially as and for the purpose specified.
In witness whereof, I, the said George Tomlinson Bousfield, have
hercunto set my hand and scal, this Twenty-first day of 1
January, in the year of our Lord One thousand eight hundred
and seventy-six.
