page_text: United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING,"
upon the condition: (amongst others) that we, the said Edwin Knowles
and George Hartley; our exccutors or administrators, by an instrument
in writing under our, or their, or one of their hands and seals,
shouk particularly describe and ascertain the nature of the said

NOW KNOW YE, that we, the said Edwin Knowles and George
Hartley, 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 and accompanying Sheet
of Drawings (that is to say) :-
.
This Invention relates to means or apparatus for working or operating
change shuttle boxes in looms of that class, wherein what are technically
known as 66
'rising boxes" are employed, that is, where a series of two,
three, or more shuttle boxes arranged one above another are caused, to
rise or fall to make the change of one box for another..
. The improvements consist in the application, to the back of tlic series
of boxes of a notch piece or notched bracket, and to the box frame,
is hinged a bell-crank lever, one arm having a finger to take into any of
the notches in the bracket when placed in suitable position, and the
other arm is formed so as to be acted upon by a lever hinged on a
bracket fixed to the loom end frame and placed in or out of position for.
action by means of a combination of levers and rods in connection with
and operated by jacquards, peg lags, or other usual indicating apparatus.
The boxes are raised by a scries of suitably formed tappets-fixed on the
crank shaft acting on a lever, in which is a friction pulley.capable of
being moved into position for contact with any of the said tappets by
means of the aforesaid combination of levers, rods, and indicating.
apparatus, whereby any of the shuttle boxes may be placed in line with
the shuttle race of the lay or lathe as may be required according to
the arrangenient of the jacquard, peg lag, or other indicating apparatus
employed.

page_text: In order that this invention may be more readily understood, we herein
give reference to an accompanying Sheet of Drawings of parts of an
· ordinary loom with our improvements applied thereto.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an end elevation of such parts only as are requisite to
illustrate the application of our Invention; and Fig. 2 is part of the
front elevation of same.
A', A², and A³, are a series of three rising boxes which are mounted
upon and capable of sliding up and down on rods B fixed in a frame C
attached to the "swords" or oscillatory arms D, which are suspended
on the frame at E in the usual manner. The boxes A are suspended by
:
rods F to a lever G, which is hinged to the frame at G', the other end
of which lever is connected by a rod G² to a lever H, in which is carried
a friction roller or pulley H¹ capable of being moved laterally therein.
This pulley H¹ either bears against a pulley I fixed on the crank shaft
of the loom and thereby maintains the box A' in the position shewn in
line with the shuttle race, or it may be placed so as to come into contact
with and be acted upon by one or other of the tappets or cams J, J¹,
and thereby to operate the lever G so as to cause one or other of the
boxes A² or A³ to be placed in line with the shuttle race. This lateral
movement of the friction roller His effected as follows:-A lever L is
hinged to the frame at L', and to the top end of which lever is jointed
a rod L, which is connected to or in communication with a lever which
is operated or actuated in one direction by ordinary jacquards, peg lags,.
or other usual indicating apparatus or pattern surface, and in the other
direction by a spring L³, and to the bottom end of the said lever L is.
a bracket H2 carrying a fork H³ which takes into a groove or betwixt
two collors formed on the shaft of the friction roller or pulley H', by
which the lateral movement is effected as indicated and required. When
the boxes are raised by the tappet J so as to bring the box A² into line
with the shuttle race they are held in that position for the picking of
the shuttle so long as may be required by means of a bell-crank lever M.
(carrying a finger N), which is: pressed by a spring M, so as to place
the finger N under the notch P formed in a bracket fixed to the back
of the boxes, or if it be desired to have the box A³ in line with the
shuttle race the said boxes are lifted by the tappet or cam J.³ into position
and are held there by the finger N taking into the notch Q. When the said

page_text: boxes are required to be lowered the finger N is pulled out of the notch
in which it happens to be by means of a lever R, which is hinged to a
bracket S fixed to the frame and brought into action by the aforesaid
lever L, as follows:-This lever R has two noses R¹ and R², either of
which may be placed in position to act upon the other end or cranked
arm M² of the bell-crank lever M by the action of the bracket H2, in
which is a slot to receive and operate a finger T fixed to the other end
of the said lever R, so that one or other of the noses will be brought
into position according to the arrangements of the jacquards, peg lags,
or other pattern surface employed for working or bringing the boxes
into line with the shuttle race, the nose R' being arranged to remove the
finger N from the notch P, while the nose R² will operate to remove it
from the notch. Q.
Having thus described the nature of our said Invention, and shewn
by Drawings the manner in which the same is performed or carried
into practice, we would have it understood that what we claim as our
Invention is, the combining and arranging parts of mechanism or
apparatus for working or operating "rising boxes," in manner sub-
stantially as herein described and shewn by the accompanying Drawings.
In witness whereof, I, the said Edwin Knowles, for and on behalf
of myself and the said George Hartley, have hereunto set my
hand and seal, this Thirtieth day of June; in the year of our
Lord One thousand eight hundred and seventy.
