I THOMAS COLEBY of Barton Square Manchester in the County of Lancaster,
Yarn Agent do hereby declare the nature of said Invention for IMPROVEMENTS IN
PRESSES FOR COMPRESSING YARNS AND OTHER MATERIALS to be as follows:-
My invention is particularly applicable to what are known as bundling presses for
compressing yarn and thread the object of my invention being to unlock and raise all
the movable top bars of the press simultaneously by one movement and to lower or
close and lock them by a single reverse movement.
In applying my Improvements to a press with several top bars I form each top
bar preferably hollow and fit in it a bolt free to be moved horizontally and to slide
easily into or out of an opening made to receive it in the corresponding front upright
bar. I pivot the back end of each top bar to move freely on a stud passed through
the top of its corresponding back upright bar I prefer to make this bar hollow or
with a groove to admit a rod to be moved vertically in it. I connect the top of this
rod to one arm of a cranked lever pivoted on the same stud as the top bar the other
arm of this lever is made to act upon the bolt and the top bar. There are as many
bolts cranked levers and connecting rods as top bars all the connecting rods being
pivoted or secured on a short shaft placed preferably below the
press table or in any
convenient manner. A hand lever and a treadle or either of them is connected in
any convenient manner to operate the connecting rods.
To open the press the hand lever or treadle is moved to raise the connecting rods
the latter acting upon the cranked levers cause them to slide the bolts out of the
front uprights and unlock the top bars the cranked levers then come against the
hinged ends of the top bars and cause them to move from a horizontal to a vertical
position thus opening the press; by moving the hand lever in the reverse direction
all the top bars are brought down and the bolts moved forward into the openings in
the front upright bars thus locking the front bars.
When my Improvements are applied to presses driven by power I may actuate
the connecting rods and top bars in the manner described or from any revolving
shaft of the press.

Improvements in Presses for Compressing Yarns and other
Materials.
I THOMAS COLEBY of Barton Square Manchester in the County of Lancaster
Yarn Agent, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
My invention is particularly applicable to what are known as bundling presses for
compressing yarn and thread the object of my Invention being to unlock and raise all
the inovable top bars of the press simultaneously by one movement and to lower or
close and lock them by a single reverse movement.
And in order that my Invention may be fully understood and readily carried into
effect I will describe the accompanying two Sheets of Drawings reference being had
to the figures and letters marked thereon.
Figure 1 is an end view of a bundling press driven by power and embodying my
Invention.
Fig. 2 is a similar view of part of the same but with the top bars shown open.
Fig. 3 is a front view of the press and Fig. 4 a back view of the upper part of
the press.
In these views the top bars are all opened or closed simultaneously by connections
operated by the power employed to work the press.
Fig. 5 is an end view of part of a press in which all the top bars are operated
simultaneously according to my Invention by a hand lever.
Referring first to Figs. 1 to 4 :-
a designates the frame of the bundling press 6 the front upright bars which are
fixed on the frame a opposite to the backplate or upper framing a¹. The movable
top bars c are provided with flanges c¹ and are pivoted loosely on a stud d which is
supported and free to turn in lugs or projections on the backplate a¹.
Within each top bar c is fitted a sliding bolt e the end of which enters a hole in
one of the front bars 6 so that all the top bars are locked when in the position
illustrated by Figs. 1, 3 and 4.
The mechanism which I employ according to my Invention for simultaneously
unlocking or locking and raising or lowering the movable bars c consists of the
following parts
:-
Each sliding bolt e is slotted at e¹ and in this slot e¹ lies the end of a lever f the
boss of which is secured upon the stud d and is formed with rack teeth which engage
similar teeth on a rod g. The rods g pass through the backplate a¹ and are connected
to a crosshead g¹ which is pivoted to and carried by two arms h h¹ fulcrumed on a
shaft i supported in hangers secured to the framing. The arm h is connected by a
rodj to an arm mj fixed on a shaft k which is supported and free to turn in brackets k¹
secured to the framing and on the shaft k is also fixed a compound lever / which is

page_text: made in two pieces connected together by pins ♬ on one part entering a slot in the
other part and a spring 12 is arranged to keep the parts of the lever in their normal
relative positions as shown.
The other arm h¹ which carries the crosshead is connected by a rod m¹ to the back
end of a lever m fulcrumed on a stud m² supported by the framing and on the front
end of this lever m is pivoted at m³ a loose piece n which is recessed where it rests
upon a stud m* secured to the lever m so that the piece n is free to turn upward
independently of the lever m but when the piece n is moved downward the lever
moves with it.
The press is worked by means of the fast and loose pulleys o mounted upon a
shaft
p upon which is fixed a pinion r which gears into a spur wheel s fast on a shaft t
on which is also fixed a pinion t¹ gearing into a spur wheel u carried by a shaft u¹.
The rim of the wheel u carries a stud u² to which are secured the ends of two
rods v pivoted on a stud ¹ carried by the frame of the table w on which the
follower w¹ is placed. There are two strikers u³ ut respectively fixed on the wheel u
which strikers are for the purpose of operating the levers land m n as hereinafter
described. On the shaft p is fixed the usual ratchet wheel p¹ the teeth of which are
engaged by a pawl p² pivoted to the frame a and a handwheel p³ is also fixed upon.
the shaft p.
The operation of the press fitted with my improvements as described is as
follows:-
Let it be supposed that a quantity of yarn has been pressed and it is desired to
open the press to remove the bundle when the parts are in the relative positions
shown on Figs. 1 and 3 the belt being upon the loose pulley.
To effect this the attendant disengages the pawl p² from the ratchet wheel pl when
the elasticity of the compressed yarn, assisted when necessary by a spring or other
mechanical contrivance, acting upon the follower w¹ causes it to descend and by
the connecting rods to turn the wheel u in the direction indicated by the
arrow Fig. 3 until the striker u³ in its downward movement comes against the loose
piece n and depresses the front end of the lever m thereby through the connecting
rod m¹ and arm ¹ raising the crosshead g¹ and with it the rods g the racks on which
turn the levers on their fulcrum the stud d thus sliding back the bolts e and
unlocking the movable top bars c and then, as the rods g are further raised, the ends
of the levers f lift the top bars c into the position shown in Fig. 2 and so open the
press by which time the follower w will have reached the bottom of the box as
shown. The bundle can then be removed and the box refilled with yarn, when this
has been done the belt is shifted from the loose pulley to the fast pulley and as the
shaft p revolves the pinion » by the wheel s drives the shaft t which transmits motion
by the pinion t¹ to the wheel u in the reverse direction to that indicated by the
arrow Fig. 3. This movement of the wheel u brings the striker u into contact with
the upper side of the compound lever when in the position shown in Fig. 2 the
effect of which is to move the said lever into the position shown in Fig. 1 thereby
operating the arm hand drawing down the crosshead g¹ and rods g and by the
movement of the levers flowering the top bars c and then sliding forward the bolts e
and locking them in their places as shown in Fig. 1. The continued movement of
the wheel u in the reverse direction to that indicated by the arrow has also the effect
of raising the follower wl by means of the rods and other connections into the
position shown in Figs. 1 and 3 thereby compressing the yarn into a bundle. The
belt is then shifted from the fast to the loose pulley by the usual automatic arrange-
ment not shown and the follower w¹ is held up by the pawl p² engaging the ratchet
wheel p¹ until the yarn in the press has been tied or banded into a bundle. The
pawl is then moved to disengage it from the ratchet wheel p¹ when the follower w¹
again descends and the press opens automatically as previously described.
From the foregoing description it will be apparent that when the lever I and its
connections are raised ready for closing the top bars and are in the positions
illustrated by Fig. 2 the lever m and its connections by which the top bars are
opened will be in the reverse positions as indicated in the same Figure.

page_text: After the striker u* has come into contact with the top side of the lever and the
top bars c have been closed as described the positions of the levers 7 and m will have
been reversed as shown in Fig. 1 the continued movement of the wheel u then
brings the striker u³ against the under side of the compound lever m n but the loose
piece n pivoted thereon allows the striker u³ to pass without operating the said lever.
Similarly on the reverse movement of the wheel u when the strikers travel in the
direction indicated by the arrow Fig. 3 the construction of the lever allows the
striker u to move the front portion back against the pressure of the spring / without
operating the connections kj etc.
Fig. 5 illustrates a press in which instead of having connections operated
automatically from the driving mechanism to open or close all the top bars c
simultaneously a hand lever y is employed fulcrumed on a shaft z and connected by
an arm y¹ to the crosshead g¹ so that by operating the lever y all the top bars c may
be unlatched and opened simultaneously and subsequently closed and locked by a
single reverse movement of the said lever.
Instead of the racks on the rods g and the teeth on the levers f, cranks f¹ as shown
in Fig. 5 or suitable equivalents might be employed and instead of the gearing
described and shown a worm and worm wheel or any other suitable arrangement of
mechanism for operating the follower might be employed. Again any convenient
arrangement of driving mechanism other than that shown might be employed and
other details might be varied or modified without departing from the nature of my
said Invention.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is-
1. Simultaneously unlocking and raising or lowering and locking as required the
movable top bars of a bundling press by the means herein shown and described or
any mere equivalents therefor.
2. The combination with the movable top bars of a press and sliding bolts or
catches for latching or locking the same, of the pivoted levers f and racks gor
cranks or equivalents operated by suitable connections from the driving mechanism
as described with reference to Figs. 1 to 4 or by a hand lever as described with
reference to Fig. 5 for the purposes specified.
3. The several constructions combinations and arrangements of parts embodying
my improvements in presses for compressing yarn etc., substantially as and for the
purposes herein described and as illustrated by the Drawings annexed.
Dated this 17th day of January 1888.
