Improvements in Double Action or Open Shed Jacquard Mechanism
of Looms for Weaving.
I, EDWARD HOLLINGWORTH, of Hutchinson, Hollingworth and Company,
Limited, of Dobcross Loom Works, Dobcross, in the County of York, Power Loom
Makers, do hereby declare the nature of this invention (which has been com-
municated to me by George Stafford and Albert Kelmel, both of Providence, in
the County of Providence and State of Rhode Island, in the United States of
America, Power Loom Makers) to be as follows:
This invention has relation more especially to open shed Jacquard machines.
There are different classes of open shed Jacquard machines, but this invention has
reference more especially to that class which is termed sometimes full open shed
machines. In a machine of this last mentioned class there is employed a stationary
griff or its equivalent, and the uprights or hooks are so constructed and operated
as that when one of the same, after having been engaged by the movable griff
and carried into its highest position, is desired to remain up for one or more
succeeding picks, each upright or hooks is caused to become engaged with the
stationary griff so that it shall not descend again until after such succeeding pick
or picks shall have become completed. It has been customary heretofore in
Jacquard machines of this class, to occasion two beats of the same pattern-card
against the needles for each pick, one of such beats occuring when the movable
griff is at its highest point, a given shed being open, and being designed to move
out of engagement with the stationary griff such of the hooks or uprights which
occupy an elevated position for that shed as should be lowered for the next shed
formation. The second beat occurs at the completion of the descent of the
movable griff and is followed immediately by the rise of such griff for the open-
ing of the said next shed. This mode of working is disadvantageous for several
practical reasons. It involves two beats of the pattern-cylinder or prism for each
pick. The quickly repeated beats of the pattern-cylinder or prism, and of the
batten carrying the said cylinder or prism, together with the chain of cards pass-
ing around the said pattern-cylinder or prism, consume power, occasion great
wear and tear on certain parts of the machine, and require such an amount of
time as to limit the speed of running of a loom having applied thereto a Jacquard
machine operating on the principle which has just been explained. It also
Occasions great wear of the pattern cards so that they are capable of being retained
in service for only a comparatively short time. The chief aim of the invention
is to obviate these disadvantages and to enable each shed formation to be effected
in the working of a full open shed Jacquard machine with a single beat only of
the card, pattern-cylinder or prism, and batten.
In order to overcome the disadvantages above referred to, I employ new and
improved mechanism for accomplishing that object, my improvements com-
prising:-
Firstly. Vertical needles are employed which rest upon transverse rods, such

page_text: needles being provided with an inclined portion. Each of the needles is formed
or provided with a broadened bearing portion, to act against a corresponding sup-
porting wire, this broadened bearing portion being provided in the case of the
needles by returning upon itself the wire of which such needle is composed,
thereby producing short parallel lengths of said wire.
Vertical flattened strips may be passed between the returns of the wire of the
needle. The inclined portion of each needle, co-operates after the fashion of a
cam in connection with the corresponding supporting wire, and inasmuch as the
said supporting wire is fixed in a convenient portion of the framework, it follows
that when the needle is moved endwise by pressure of a blank or unperforated
portion of the pattern-card, so as to move the inclined portion thereof over and
in contact with the said supporting wire, the needle itself is caused to have a
slight extent of vertical movement. The rear ends of the needles are formed
or provided with hooks or other projections, or otherwise are constructed to be
engaged with the blades of a horizontally reciprocating griff or equivalent engag-
ing device, which is mounted to move horizontally on suitable supports, and is
connected at each end thereof by a rod to an arm, the latter being pivoted and
provided with a pin or roller working against a cam fast on a rock-shaft. The
said griff or equivalent engaging device, moves back and forth in a horizontal
direction without engagement of the blades or other engaging portions thereof
with the projections or hooks of the needles, so long as the said needles remain
in their normal positions, the blades thereof passing above the said hooks or pro-
jections on said needles. When, however, a needle is moved endwise by the
pattern-card, so as, by the action of the inclined portion thereof in connection with
the corresponding supporting wire, to occasion a sufficient extent of vertical move-
ment of the needle to bring its projection or hook into the range of movement of
the adjacent griff-blades of the griff, then, in the ensuing outward movement of
the said griff the said needle will be engaged by the said adjacent griff-blade and
will be carried outward thereby, thus occasioning a lateral deflection of the up-
right which is engaged by the said needle out of the path of movement of the
ascending griff.
The operation of a Jacquard machine having applied thereto the described
embodiment of my invention, so far as the same is modified in consequence of the
invention, is as follows;-
The beat of the pattern-card against the needles which takes place when the
moving-griff is in its highest position, is followed promptly by a slight outward
movement of the horizontally moving griff or equivalent engaging device. This
outward movement is sufficient to place its blades in engagement with the hooks
on those needles which have been uplifted in consequence of the action of their
cam-shaped portions upon the rods before mentioned. As herein before indicated
this action results from the endwise movement of such needles which is caused by
pressure of blank or unperforated portions of the card against the ends of the
needles. This outward movement of the said griff is due to the action of a cam
against a roller on an arm which is connected with the said horizontally-recipro-
cating griff. During the descent of the vertically moving griff the horizontally
moving griff remains in engagement with the hooks of the needles, but without
further outward movement. During this time a roller bears against a concentric
portion of the said cam. At the time of the completion of the descent of the
vertically-moving griff, the cam-grade acts against said roller to press the
horizontally-reciprocating griff outward into its extreme position. In this last
part of its outward movement the horizontally-moving griff takes with it all the
needles, which by the beat of the pattern-card against the same were moved or
pressed back by the blank or unperforated portions of the said pattern-card,
whereby the said horizontally-reciprocating griff operates to occasion the same
selection of the uprights which for the time being are in their lowered position
as ordinarily is effected by the second beat of the same pattern-card.
Secondly. My invention consists in combining means whereby as each of the

page_text: moving griffs in turn descends, the disengaged hooks of the uprights which are
engaged and descending therewith are pressed back, so that the said hooks thereof
shall be out of the path of the ascending griff, consequently I prevent the ascending
griff from picking up a descending upright and raising it at a time when it should
be lowered into a depressed position. I use, by preference, wires, which are
arranged to engage with the uprights and are moved transversely with relation
to the griffs at the proper moment in the working of the Jacquard-machine, so
as to press the disengaged hooks on the said uprights out of the path of the
ascending griff-blades. The said wires or their equivalents may be variously
constructed, arranged, and applied. Springs may be employed to press the wires
or needles toward the left. When these wires are moved toward the right, they
press the limbs of the uprights to the right also, thereby carrying laterally clear
of the ascending griff-blades those hooks which are not in engagement with either
the ascending griff-blades or the descending griff-blades. The mode of operat-
ing the wires or their equivalents and of arranging and connecting the same with
their actuating devices may be varied. A press bar is arranged to act against the
ends of all the wires, so that when movement is is given to the said press-bar
toward the right all the limbs of all the uprights shall be pressed in the same
direction. This will operate to carry toward the right clear of the ascending
griff-blades all the hooks which are not in engagement with moving-griff-blades.
The movement will not be sufficient to disengage from the moving-griff-blades
the hooks which are in engagement therewith, and the limbs on which such hooks
are formed will simply bend under the pressure which is exerted against them by
the wires. For the purpose of operating the press-bar at the proper times I pro-
vide an arm or arms on a rock-shaft. The said rock-shaft is provided with a cam-
shaped arm against which latter acts a roller, carried by a projection from one
of the moving-griff-frames. The roller acts against the cam-shaped portion of
the arm in both the upward movement and the downward movement of the griff-
frame, so that the wires are operated in proper season every time the respective
griff-blades pass each other.
In some cases it may be desired to press back only one-half of the said limbs
at a time in order to reduce the strain on the parts which operate the press-back
devices as well as in order to lessen the danger of accidental dislodgment of the
hook of an upright from the griff-blade with which such upright is descending.
To this end the wires or their equivalents may be divided into two sets, and the
operating devices may be so contrived as to operate the said sets alternately, so
that at each action of the parts only those wires shall be pressed back which
correspond with the limbs that normally co-operate with the particular griff
which for the time being is rising. Therefore, the press-bar is arranged to
operate only a part of the wires at each movement of the same to the right, the
remaining part of such wires being operated at the next movement of the press-
bar to the right, and so on. I arrange the wires or needles in two sets one above
the other and combine with the press-bar means of shifting the same vertically,
so that when in one position it shall act against the upper set of wires or the
equivalent thereof and when in the other position it shall act to move the other
set of wires or the equivalent thereof. Each end of the said press-bar is supported
by a carrier, the said carrier having therein a horizontal slot, which receives the
said end of the press-bar and along which the said end is free to move toward and
from the ends of the wires by means of the actuating devices. The upper part of
the carrier is formed with lugs, having holes therethrough, the said holes
receiving guide-pins, which are applied to a stand, which is connected with a fixed
part of the framework. A pin, or the like, projecting from an arm or bracket,
operates the carrier by striking against the lugs as the griff-frame with which
such projection is connected nears the respective ends of its vertical reciproca-
tion, thereby shifting the said carrier and with it the press-bar so that the said
press-bar shall be placed in position to operate one set of the wires, during the
descent of the griff-frame, and then placed in position to operate the other set of

page_text: wires during the rise of said griff-frame. Sufficient friction between the carrier
and the guide-pins is provided for in order to enable the carrier to remain in its
elevated position after being raised by contact of projection with an upper lug
in the ascent of the griff-frame, until it is depressed positively by the ongage-
ment of the pin with a lower lug in the descent of the griff frame.
Thirdly. My invention consists in bending the two limbs of each double up-
right toward each other forming a reduced neck, with portions, of greater width
below and above such neck, The neck and wider portions above and below the
same co-act with wires, or equivalent bearings relatively to which the double up-
rights move as they ascend and descend in unison with the griffs. The said
wires or bearings are mounted in a fixed portion of the framing of the machine,
in the upper portion thereof. They co-operate with the double up-right in each
rise or fall of the up-right, to cause a backward movement or recession of the
upper portion of the upright at the time when the two sets of griff-blades are
passing each other, which is the time at which the ascending griff is likely to pick
up the descending upright and carry it again into an elevated position. This
backward movement or recession of the upright is not sufficient to disengage the
hook thereof which is engaged with a moving griff-blade from the said griff-
blade, but is sufficient to press back the disengaged hook of such upright out of
the path of the adjacent oppositely-moving griff-blade.
Fourthly. The press-back wires are mounted in a movable carrier, consisting
of cross-bars to which the opposite ends of the wires are applied, and support
arms by which the said cross-bars are upheld, and slide rods to which the sup-
porting arms are attached. With the carrier for the press-back wires is combined
means for reciprocating the said carrier horizontally in proper timing, with refer-
ence to the movements of the two moving grifts, whereby each time the said
moving griff's pass each other the carrier and press-back wires are operated to
bear the uprights laterally, in order to move the hooks of the disengaged
descending uprights laterally clear of the blades of the ascending griff, and
thereby prevent the engagement of such hooks with the said blades. Prefer-
ably, I arrange for operating the carrier from one of the moving griffs, or a part
connected and moving in unison therewith, thus I employ a cam in engagement
with a pin or roller, one of the said parts being connected to move with one of
the moving griffs and the other being connected with the carrier. In the present
embodiment of the invention the cam, is attached to the slide-rod of the griff-
frame, while the roller which is engaged by the said cam, is mounted
on a pin which is attached to a slide-rod. The cam preferably is
a slotted cam SO that it shall operate to move the carrier positively
in both directions horizontally, and is shaped to occasion a complete recipro-
cation of the said carrier in each complete vertical movement of the cam up or
down. Thereby, each time the moving griffs pass each other at an intermediate
point in their vertical traverse, the carrier with the press-back wires mounted
therein is moved toward the right so as to carry the disengaged hooks of the
uprights out of the path of movement of the ascending griff-blades.
The ends of the press-back wires or needles are inserted into horizontal holes
in the said cross-bar. The right hand ends of the said wires are bent to form
eyes through which are passed the stems of pins entering vertical holes that are
provided in the said cross-bar. This manner and means of applying and con-
necting the press-back wires to the cross-bars provides conveniently for the sup-
port and retention of the said wires in the carrier and facilitates the application
and removal thereof.
To each slide rod of the carrier is applied and made fast a collar, the said
collar being located at or near mid-length of the said slide-rod. This collar is
formed or provided with an arm or lug and to the said collar and arm or lug a
vertical strip is affixed, by means of a bolt. To the depending portions of the
strips are secured the opposite ends of a bar extending crosswise of the machine,

page_text: immediately below the press-back wires or needles, and parallel with the cross-
bars. The press-back wires or needles rest upon the upper surface of this cross-
bar, or else are located normally immediately adjacent to such surface, so that the
said cross-bar constitutes a stay or support for the intermediate portions of the
said wires or needles. Pins are driven into the top of the cross-bar, between
the press-back wires or needles, to separate the latter from one another, and
restrain them from transverse or side movement. The said pins are headed, and
the heads thereof serve to keep the press-back wires or needles from rising away
from the cross-bar. The said cross-bar, or intermediate rest, as it may be termed,
reciprocates horizontally in unison with the carrier and the press-back wires or
needles, it being in effect a part of the carrier. During the operation of the
Jacquard mechanism having the present invention applied thereto, the rising
and falling of the uprights produces sufficient friction where they make contact
with the press-back wires or needles to tend to keep these latter continually
jumping, and this would occasion unnecessary wear thereof if the jumping were
not prevented. The intermediate rest with its headed pins, restrains the press-
back wires or needles from unnecessary movement, either sidewise or vertical.
Preferably, the pins are of the character or construction known as split, or spring,
or cotter-pins, and this facilitates their application to the rest, or their removal
therefrom, rendering such removal and subsequent replacing of the said pins
convenient and easy whenever the press-back wires or needles require any."
attention.
The press-back wires or needles are formed or constructed as will now be
described. Each wire or needle is formed with a succession of half-eyes therein
for the reception of the prolongations of the uprights above the upper hooks of
the latter, these half-eyes being, for example, of semi-circular shape. Two wires
or needles are used in conjunction, one thereof being located immediately above
the other, the said wires or needles being turned so that their half-eyes face in
opposite directions, whereby each of such wires or needles serves to retain the
limbs of the corresponding series of uprights in the half-eyes of the other of
such wires or needles. This use of wires or needles in pairs, and formed with
half-eyes, enables me to avoid the use of wires or needles having round eyes, as
usual heretofore in Jacquard mechanism. The wires or needles with half-eyes
are cheaper to make, are much more easily and conveniently put into the
machine and taken out again, and have no objectionable features in operation.
Fifthly. I arrange that each engagement of the cam and roller, (this engage-
ment occuring each time the two moving griffs are about to pass each other)
occasions a movement of the carrier and press-back wires to the right. This
operates to carry toward the right, also, clear of the ascending griff-blades, all
the hooks which are not in engagement with moving griff-blades. Those limbs
having the hooks thereof engaged with such griff-blades will ordinarily bend under
the pressure which is exerted against them by the press-back wires or needles,
and it is not intended that the hooks of such limbs should become dislodged from
the griff-blades on which they are seated. However, in order to guard against the
liability of such dislodging, I provide in connection with the uprights springs
which shall yield under the pressure of the press-back wires or needles, thereby
relieving the strain at the hooks which would tend to dislodge the same from the
griff-blades. This is effected very conveniently by providing the limbs of the
uprights themselves with springs located between the points at which the hooks
are formed or provided on such limbs and the points at which the press-back
devices take bearing against such limbs. The said springs may be formed
variously, and are of such strength that so long as the hooks of the uprights are
disengaged from the griffs the springs shall not yield under the pressure of the
press-back devices, the latter and the uprights operating the same as if the
springs were not present. However, a hook being engaged with a moving-griff-
blade, the action of the press-back devices against the upright, occasions a yield-

page_text: ing of the spring, thereby relieving the hook from strain which might operate
to dislodge the same and obviating the tendency to the production of faults in the
weaving.
Sixthly. My invention here has reference more particularly to the springs
referred to in the fifth part of this specification and consists in interposing such
springs between the wires or needles and uprights, and which springs are intended
to yield under the pressure of the press-back wires or needles and thereby relieve
the strain at the hooks which would tend to dislodge the latter from the griff-
blades.
The said springs are each in the form of a narrow elongated U and are mounted
with their free extremities extending downward. The said springs are hung
upon cross-rods supported by side-bars made fast to the carrier for the press-back
wires or needles, or the said springs may conveniently be hung or supported in
any suitable manner. The two ends of each spring are introduced, together
with the upper end of one limb of an upright into one of the elongated eyes, of
one of the wires or needles. The expansion of the spring within the said
elongated eye holds the said limb pressed up against one end of the said eye.
When the carrier and with it the said wire or needle is moved in manner as
described above toward the right, the pressure that is transmitted from the wire
or needle through the spring to the limb of the upright bears the said limb to the
right, also, so as to tend to move the said limb sufficiently to bear its hook out
of the way of the griff-blade which is adjacent thereto. Should, however, the said
hook be in engagement at such times with the said griff-blade and moving in
unison therewith, the said spring will yield and become compressed under the
resistance which the limb of the upright offers to being moved laterally and
thus the strain exerted against the said limb will be relieved, so that the said
hook will not be forced off the griff-blade. The wires or needles are formed in
the present embodiment of my invention of flat metal strips, each punched with
a number of elongated eyes. The ends of said wires or needles are sprung into
holes prepared therefor in the cross-bars of the carrier.

Improvements in Double Action or Open Shed Jacquard Mechanism
of Looms for Weaving.
I, EDWARD HOLLINGWORTH, of Hutchinson, Hollingworth and Company,
Limited, of Dobcross Loom Works, Dobcross, in the County of York, Power Loom
Makers, do hereby declare the nature of this invention (which has been com-
municated to me by George Stafford and Albert Kelmel, both of Providence, in
the County of Providence and State of Rhode Island, in the United States of
America, Power Loom Makers) and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention has relation more especially to open shed Jacquard machines.
There are different classes of open shed Jacquard machines, but this invention
has reference more especially to that class which is termed sometimes full open
shed machines. In a machine of this last mentioned class there is employed a
stationary griff or its equivalent, and the uprights or hooks are so constructed
and operated as that when one of the same, after having been engaged by the

page_text: moveable griff and carried into its highest position, is desired to remain up for
one or more succeeding picks, each upright or hook is caused to become engaged
with the stationary griff so that it shall not descend again until after such
succeeding pick or picks shall have become completed. It has been customary
heretofore in Jacquard machines of this class, to occasion two beats of the same
pattern-card against the needles for each pick, one of such beats occuring when
the moveable griff is at its highest point, a given shed being open, and being
designed to move out of engagement with the stationary griff such of the hooks
or uprights which occupy an elevated position for that shed as should be lowered
for the next shed formation. The second beat occurs at the completion of the
descent of the moveable griff and is followed immediately by the rise of such
grift for the opening of the said next shed. This mode of working is dis-
advantageous for several practical reasons. It involves two beats of the pattern-
cylinder or prism for each pick. The quickly repeated beats of the pattern-
cylinder or prism, and of the batten carrying the said cylinder or prism, together
with the chain of cards passing around the said pattern-cylinder or prism,
consume power, occasion great wear and tear on certain parts of the machine,
and require such an amount of time as to limit the speed of running of a loom
having applied thereto a Jacquard machine operating on, the principle which has
just been explained. It also occasions great wear of the pattern cards so that
they are capable of being retained in service for only a comparatively short time.
The chief aim of the invention is to obviate these disadvantages and to enable
each shed formation to be effected in the working of a full open shed Jacquard
machine with a single beat only of the card, pattern-cylinder or prism, and
batten.
In order to overcome the disadvantages above referred to, I employ new and
improved mechanism for accomplishing that object, which is illustrated in the
accompanying drawings, where Fig. 1 is a side elevation of a Jacquard machine,
Fig. 2, is a view of the inside of the machine Fig. 3, is plan on enlarged scale,
shewing a needle and certain parts adjacent thereto, and Fig. 4 is a view in vertical
section on an enlarged scale shewing certain of the parts while are found at the
left hand side in the other figures.
1 designates one of the side-frames of a Jacquard machine. 2, 2, designate
blades of a vertically-moving griff. The said blades are shewn in dotted lines
in their lowest position in Fig. 2, and in full fines in their highest position.
3 (see Fig. 1) designates the griff-frame in which the said griff-blades 2, 2, are
mounted. The said griff-frame is operated in practice in any suitable manner,
not necessary to be shewn or described. 7, 7, are upright wires provided with
hooks 8, 8, for engagement with the griff-blades 2, 2, as usual. 9, 9, are needles
co-operating with the said hooked uprights 7, 7, and disposed as usual in
horizontal or substantially horizontal position. 10 is the pattern-cylinder or
prism around which are passed the usual pattern-cards, not shewn, the said
pattern-cylinder or prism being in practice mounted as usual in a swinging
frame or batten (not shewn) which is actuated in customary manner, and the
said pattern-cylinder or prism being rotated intermittently in customary manner.
19, 19, Figs. 1 and 2, are stationary griff-blades which are mounted in a fixed
griff-frame 20, or other convenient support. The uprights 7, 7, are furnished or
formed each with a second hook 21 in addition to hook 8, mentioned above, this
second hook being for engagement with the stationary griff-blades 19, 19. The
hooks 21, 21, become engaged with the said stationary griff-blades 19, 19, after
the uprights 7, 7, have been raised into their highest position, and thereby the
said uprights are held in their upraised position until by the working of the
mechanism they are caused to descend again. The strain that is transmitted
through the cords which in practice are connected with the lower ends of the
uprights or hooks 7, 7, draws the lower ends of the upraised uprights into
position for engagement with the griff-blades 19, 19, as in the case of the
uprights and g in Fig. 2.

page_text: Figs. 1 and 2 shew the moving griff in its highest position, with the up-
rights d, e, f, g, supported thereby, the shed being supposed to be open. It usually
happens that at each descent of the vertically-moving griff preparatory to the
formation of a new shed, certain of the uprights 7, 7, which previously were
lifted by the said moving griff and allowed to engage by their hooks 21, 21, with
the stationary griff-blades are required to descend in unison with the said moving
griff. It has been customary heretofore to occasion a selection of the uprights
which are required to descend, and to provide for their descent in unison with
the moving griff, by causing the pattern-cylinder or prism to beat up when the
moving griff is at its highest point, so as to present against the ends of the
needles 9, 9, the pattern-cards corresponding with the next shed which is to be..
produced in the warp-threads. As will be understood by those who are versed
in the art, the blank or unperforated portions of the said card correspond with
the uprights which are to occupy their lowermost position when the next shed is
open. Consequently, when the said pattern-card is carried against the ends of
the needles 9, 9, the moving griff being in its highest position and engaging with
the hooks 8, 8, of the uplifted uprights 7, 7, at which time the said griff
supports the said uplifted uprights with their hooks 21, 21, slightly above and
free from the stationary griff-blades see Fig. 2, the pressure of such blank or,
unperforated parts of the said cards as come opposite needles pertaining to
uplifted uprights will carry the said uprights into the position that is occupied
by the uprights d and e of Fig. 2, that is to say, free of the stationary griff-blades,
80 that in the ensuing descent of the moving griff such uprights
will go down with it. At the time of such descent those among
the uplifted uprights which are not pressed laterally as in the case
of the uprights and e, but which are allowed to remain in the
position that is occupied by the uprights f and g, will settle back on to the
stationary griff-blades 19, 19, and be held thereby in elevated position. As stated
herein before, it has been customary in machines of the class to which the present
invention relates to occasion a second beat of the same pattern-card against the
ends of the horizontal needles 9, 9, at the end of the descent of the vertically-
moving griff, and prior to the ensuing ascent of the said griff, such second beat of
the said pattern-card being intended to effect the selection of the uprights which,
being in their lowest position, are to be elevated for the shed which
opened by such rise of the said moving griff. In accordance with my invention
I dispense with the necessity for making the second beat of the pattern-card
against the needles, by providing devices which operate substantially as I shall
now proceed to set forth in connection with the needles and uprights, and whereby,
prior to the rise of the moving griff, the uprights which the said pattern-card
indicates for being left in their lowest position shall be prevented from becoming
engaged with the ascending griff.
to be
I will now proceed to describe the parts in which my invention more
immediately resides.
Firstly. In the drawings, the rear ends of the needles are shewn as supported
upon traverse rods 24, 24, that preferably are arranged in a vertical series as
shewn. Adjacent to each rod 24 the needle 9 which rests thereon is formed or
provided with an inclined portion 25, see more particularly Fig. 4.
Each of the
needles is formed or provided with a broadened bearing portion, to act against
the corresponding supporting wire 24, this broadened bearing portion being
provided in the case of the needles which are shewn in the drawings by returning
upon itself the wire of which such needle is composed, thereby producing short
parallel lengths of said wire as at 26 in Fig. 3. Vertical flattened strips, as 261,
may be passed between the returns of the wire of the needle. The inclined
portion 25 of each needle, as will be obvious, co-operates after the fashion of a
cam in connection with the corresponding supporting wire. 24, and inasmuch as
the said supporting wire is fixed in a convenient portion of the framework,
as at 27 in Fig. 4, it follows that when the needle is moved endwise to the left by

page_text: pressure of a blank or unperforated portion of the pattern-card, so as to move
the inclined portion 25 thereof over and in contact with the said supporting
wire 24, the needle itself is caused to have a slight extent of vertical movement.
This is indicated in the case of needles l, m, n, and o, in Figs. 2 and 4. The
rear ends of the needles 9, 9, are formed or provided with hooks or other
projections as at 28, 28, Figs. 2 and 4, or otherwise are constructed to be engaged
with the blades 29, 29, of a horizontally reciprocating griff or equivalent engaging
device, the framework of which last is designated 30. This griff is mounted to
inove horizontally on suitable supports, not shown herein and of obvious and
well-known character. It is connected at each end thereof by a rod 31 to an
arm 32, the latter being pivoted at 33 and provided with a pin or roller 34 working

ing device, moves back and forth in a horizontal direction without engagement
of the blades or other engaging portions thereof with the projections or hooks of
the needles 9, 9, so long as the said needles remain in their normal positions, as
in the case of the needles i, j, k, and p, the blades thereof passing above the said
hooks or projections 28, 28. When, however, a needle is moved endwise by the
pattern-card, as in the case of the needles I, m, n, and o, so as, by the action of the
inclined portion 25 thereof in connection with the corresponding supporting
wire 24, to occasion a sufficient extent of vertical movement of the needle to bring
its projection or hook into the range of movement of the adjacent griff-blades 20
of the griff 30, then, in the ensuing outward movement of the said griff the said
needle will be engaged by the said adjacent griff-blade and will be carried
outward thereby, thus occasioning a lateral deflection of the upright which
is engaged by the said needle out of the path of movement of the ascending
griff.
The operation of a Jacquard machine having applied thereto the described
embodiment of my invention, so far as the same is modified in consequence of
the invention, is as follows:-
The beat of the pattern-card against the needles 9, 9, which takes place when
the moving-griff is in its highest position as hereinbefore stated, is followed
promptly by a slight outward movement of the horizontally moving-griff 30 or
equivalent engaging device. This outward movement is sufficient to place its
blades in engagement with the hooks 28, 28, on those needles 9, 9, which have
been uplifted in consequence of the action of their cam-shaped portions 25, 25,
upon the rods 24, 24. See dotted lines in Fig. 4. As hereinbefore indicated
this action results from the endwise movement of such needles that is caused
by pressure of blank or unperforated portions of the card against the ends of the
needles. This outward movement of the said griff 30 is due to the action of the
grade 51 on the cam 35 against the roller 34 on the arm 32 which is connected
with the said horizontally-reciprocating griff. During the descent of the
vertically-moving griff the horizontally moving griff remains in engagement with
the hooks of the needles 9, 9, but without further outward movement. During
this time the roller 34 bears against the concentric portion 352 of the cam 85.
At the time of the completion of the descent of the vertically-moving griff the
cam-grade 353 acts against the roller 34 to press the horizontally-reciprocating
griff outward into its extreme position. In this last part of its outward move-
ment the horizontally-moving griff takes with it all the needles 9, 9, which by
the beat of the pattern-card against the same were moved or pressed back by
the blank or unperforated portions of the said pattern-card, thereby the said
horizontally-reciprocating griff operates to occasion the same selection of the
uprights which for the time being are in their lowered position as ordinarily is
effected by the second beat of the same pattern-card.
Secondly. My invention consists in combining means whereby as each of the
moving griffs in turn descends, the disengaged hooks of the uprights which are
engaged and descending therewith are pressed back, so that the said hooks
thereof shall be out of the path of the ascending griff, consequently I prevent the

page_text: ascending griff from picking up a descending upright and raising it at a time
when it should be lowered into a depressed position. Figure 5 of the drawings
shews in side elevation certain portions of a double-action Jacquard-machine
having one embodiment of my invention applied thereto, only such old parts
being shewn as are necessary to make clear the relations and mode of operation of
my new devices. Fig. 6 is a view in transverse vertical section of the parts which
are represented in Fig. 5. Figs. 7 and 8 are views in elevation at right angles to
each other shewing certain parts which co-operate in raising and lowering the
press-bar of Figs. 5 and 6. Fig. 9 is a view in vertical section corresponding
with a part of Fig. 6, but shewing a modification.
The framing and certain fixed parts which are applied thereto are designated 11
in the various views or figures of the drawings, the usual bottom board being
designated 2, the uprights being designated 33, the usual needles co-operating
therewith being designated 4 4, the springs which are applied to the said needles
being designated 5 5, and the usual card-cylinder or prism being designated 6.
7 and 8 respectively designate the two moving griff-frames, the blades applied
thereto being designated, respectively, 71 and 81 and being arranged in alternat-
ing succession, as shewn. The two griff-frames 7 and 8 are shewn as mounted,
respectively, on the slide rods 9 and 10, as usual, the said slide-rods being fitted
to move in guides 11 11 on the fixed framework of the machine, all as usual, and
the griff-frames being in practice actuated through suitable power connections,
but not necessary to be shewn or described herein, and thereby being caused to
move simultaneously in opposite directions with respect to each other.
The card-cylinder or prism 6 in practice will be supported and operated by
devices of usual character and construction, (not herein shewn) and thereby
will be caused to make one beat for each shed formation this usually corre-
sponding with one pick of the loom to which the Jacquard-machine is applied.
The uprights 33 are each provided with two hooks, as 31 31, for engagement
with the respective moving griffs, and in the present embodiment of the invention
the said uprights are double, as shewn, each limb of each of such uprights
having a hook 31. One hook 31 of each upright is designed for co-operation
with a griff-blade 71, and the other hook 31 thereof is designed for co-operation
with the adjacent griff-blade 81, one of such griff-blades being designed to be
uplifted for one shed and the other thereof being designed to be uplifted for the
succeeding shed, and so on in regular alternation.
12 12 designate the blades of a stationary griff such as sometimes is employed
(that is to say, in full open-shed Jacquard-machines) when it is desired that an
upraised upright shall remain in its elevated position for several picks in
succession without being caused to descend meanwhile.
32 32 designate hooks that are formed on the uprights 3 3 for engagement with
the said griff-blades 12 12.
The devices which have been described thus far are common to pre-existing
Jacquard-machines.
With the foregoing devices I combine means whereby as each of the moving
griffs in turn descends, the disengaged hooks 31 of the uprights which are engaged
and descending therewith are pressed back, so that the said hooks thereof shall
be out of the path of the ascending griff. Thereby I prevent the ascending
griff from picking up a descending upright and raising it at a time when it
should be lowered into a depressed position. I use by preference, wires, which are
arranged to engage with the uprights 33 and are moved transversely with relation
to the griffs at the proper moment in the working of the Jacquard-machine,
so as to press the disengaged hooks on the said uprights out of the path of the
ascending-griff-blades. The said wires or their equivalents may be variously
constructed, arranged, and applied. I have shewn them herein as constituting
a set of supplemental needles, the same being designated 13 13 and having eves
or the equivalent thereof where they engage with the uprights 33, as at 131 131.
Springs as at 132 132, may be employed to press the wires or needles 13 13 toward
E

page_text: the left in the drawings. When these wires are moved toward the right in the
drawings, they press the limbs of the uprights to the right also, thereby carrying
laterally clear of the ascending griff-blades those hooks 31 31 which are not
in engagement with either the ascending griff-blades or the descending griff-
blades. The mode of operating the wires 13 13 or their equivalents and of arrang-
ing and connecting the same with their actuating devices may be varied. In
Fig. 9I shew a press-bar 14, arranged to act against the ends of all the
wires 13 13, so that when movement is given to the said press-bar 14 toward the
right in the said figure all the limbs of all the uprights 33 shall be pressed in the
same direction. This will operate to carry toward the right clear of the ascending
griff-blades all the hooks which are not in engagement with moving griff-blades.
The movement will not be sufficient to disengage from the moving griff-blades the
hooks which are in engagement therewith, and the limbs on which such hooks
are formed will simply bend under the pressure which is exerted against them
by the wires 13 13. For the purpose of operating the press-bar 14 at the proper
times I provide an arm or arms 15 on a rock-shaft 16. The said rock-shaft is
shewn provided with a cam-shaped arm. 17, against which latter acts a roller 18,
carried by a projection 19 from one of the moving griff-frames, as at 8. The
roller 18 acts against the cam-shaped portion of the arm 17 in both the upward
movement and the downward movement of the griff-frame &, so that the
wires 13 13 are operated in proper season every time the respective griff-blades 7.1
and 81 pass each other.
The arrangement that is shewn in Fig. 9 is intended to press back all the
limbs of the double uprights at every action of such bar. In some cases it
may be desired to press back only one-half of the said limbs at a time in order
to reduce the strain on the parts which operate the press-back devices as well as
in order to lessen the danger of accidental dislodgment of the hook of an upright
from the griff-blade with which such upright is descending. To this end the
wires 13 13 or their equivalents may be divided into two sets, and the operating
devices may be so contrived as to operate the said sets alternately, so that at
each action of the parts only those wires shall be pressed back which correspond
with the limbs that normally co-operate with the particular griff which for the
time being is rising. In Figs. 5 to 8, therefore, the press-bar 14 is arranged
to operate only a part of the wires 13 at each movement of the same toward the
right, the remaining part of such wires being operated at the next movement
of the press-bar to the right, and so on. In these figures I have arranged the
wires or needles in two sets one above the other and have combined with the
press-bar 14 means of shifting the same vertically, so that when in one position
it shall act against the upper set of wires 13 or the equivalent thereof and when
in the other position it shall act to move the other set of wires 13 or the equi-
valent thereof. Each end of the said press-bar is supported by a carrier 20,
the said carrier having therein a horizontal slot 211, which receives the said end
of the press-bar and along which the said end is free to be moved toward and
from the ends of the wires 13 13 by means of the actuating devices, which have
been described. The upper part of the carrier 20 is formed with lugs 21 21
having holes therethrough, as indicated in dotted lines at 22, (see more particu-
larly Fig. 7) the said holes receiving guide-pins 23, which are applied to a
stand 24, which is connected with a fixed part of the framework.
A pin or the
like, as at 25, projecting from the arm or bracket 19, operates the carrier 20
by striking against the lugs 26 26 respectively, as the griff-frame 8 with which
such projection 25 is connected nears the respective ends of its vertical reciproca-
tion, thereby shifting the said carrier and with it the press-bar, so that the said
press-bar shall be placed in position to operate one set of the wires 13 during
the descent of griff-frame 8, and then placed in position to operate the other set
of wires during the rise of griff-frame S. Sufficient friction between the car-
rier 20 and the guide-pins 23 is provided for in order to enable the carrier to
remain in its elevated position after being raised by contact of projection 25

page_text: with the upper lug 26 in the ascent of griff-frame S until it is depressed positively
by the engagement of the pin 25 with the lower lug 26 in the descent of the
griff-frame S.
Thirdly. In the accompanying drawings Fig. 10 is side elevation of certain
portions of a double-action Jacquard machine having one embodiment of my
invention applied thereto, only such old parts being shewn as are necessary to
make clear the relations and mode of operation of my invention.
My invention consists in bending the two limbs of each double upright toward
each other as shewn forming a reduced neck, as 33, with portions, 34, 35, of
greater width below and above such neck. The neck and wider portions above
and below the same co-act with wires 13, 13 and 14, or equivalent bearings
relatively to which the double uprights move as they ascend and descend in
unison with the griffs. The said wires or bearings are mounted in a fixed por-
tion of the framing of the machine, in the upper portion thereof. They co-
operate with the double upright in each rise or fall of the upright, to cause a
backward movement or recession of the upper portion of the upright at the
time when the two sets of griff-blades are passing each other, which is the time at
which the ascending griff is likely to pick up the descending upright and carry
it again into an elevated position. This backward movement or recession of
the upright is not sufficient to disengage the hook thereof which is engaged with
a moving griff-blade from the said griff-blade, but is sufficient to press back the
disengaged hook of such upright out of the path of the adjacent oppositely mov-
ing griff-blade.
Each upright acts in connection with two of the bearings 13, 13, which latter
are spaced at a distance apart corresponding with the width of the portions 34
and 35 of the uprights which are next adjacent above and below the neck 33.
The said bearings 13, 13, serve to maintain the upright in its normal vertical
position, except during the period of rearward deflection of the upright at the
time when the two sets of griff-blades are passing each other. The bearing 14, in
each movement of the upright up or down, by its engagement with the shoulders
at the front of the head 35, operates to deflect the upright rearwardly. The rear
bearings 1, by its engagement with the shoulders above and below the neck 33,
operates to deflect the upright forwardly again. The bearing 14 is located at a
higher level than the bearings 133, 13, and at an intermediate position, hori-
zontally, with reference to the two latter, in order to enable it to act in connec-
tion with the upright to occasion the desired rearward deflection of the latter.
The first upright at the left in Fig. 10 is shewn in a depressed position, with the
head of the same fitting between two of the bearings 13, 13. The second
upright in the said figure is shewn in an intermediate elevation, with the upper
portion thereof deflected rearwardly through its engagement with bearing 14.
In this position of the upright the rear bearing 13 enters the recess at the rear
of the neck 33. The third upright in the said figure is shewn in its full elevated
position, with bearing 14 received in the recess at the front of the neck 33.
Fourthly. My invention relates to another means whereby as each of the mov-
ing griffs in turn descends, the disengaged hooks of the uprights which are
engaged and descending therewith are pressed back, so that the said hooks
thereof shall be out of the path of the ascending griff, consequently I prevent
the ascending griff from picking up a descending upright and raising it at a
time when it should be lowered into a depressed position.
Fig. 11 of the drawings shews in side elevation certain portions of a double-
action Jacquard machine having one embodiment of my invention applied thereto,
only such old parts being shewn as are necessary in order to make clear the
relations and mode of operation of my new devices.
Fig. 12 is a view mainly in transverse vertical section shewing certain of
the parts which are represented in Fig. 11. Fig. 13 is a plan view of certain of
the parts which are represented in Figs. 11 and 12, the same being drawn on

page_text: an enlarged scale. Fig. 14 is a view in detail shewing more especially the form
of the press-back wires and the manner of engagement with the uprights.
Fig. 15 is a view in vertical section on the plane that is indicated by the dotted
line 5, 5, in Fig. 12, looking in the direction of the arrows which are located
adjacent to the ends of the said dotted line.
The press-back wires 13, 13, are mounted in a moveable carrier, herein shewa
as consisting of cross-bars 33, 331, to which the opposite ends of the wires 13, 13.
are applied, supporting arms 34, 34, by which the said cross-bars are upheld,
and slide-rods 35, 35, to which the supporting arms 34, 34, are attached. With
the carrier for the press-back wires is combined means for reciprocating the
said carrier horizontally in proper timing, with reference to the movements of
the two moving griffs, whereby each time the said moving griffs pass each other
the carrier and press-back wires are operated to bear the uprights laterally, in
order to move the hooks of the disengaged descending uprights laterally clear
of the blades of the ascending griff, and thereby prevent the engagement of such
hooks with the said blades. Preferably, 1 arrange for operating the carrier
from one of the moving griffs, or a part connected and moving in unison there-
with. Thus, I have shewn in the drawings a cam in engagement with a pin or
roller, one of the said parts being connected with the carrier. In the present
embodiment of the invention the cam, herein designated 36, is attached to the slide-
rod 9 of the griff-frame 7, while the roller which is engaged by the said cam, the
same being designated 37 herein, is mounted on a pin 38, which is attached to
a slide-rod 35. The cam 36 preferably is a slotted cam, as shewn, so that it
shall operate to move the carrier positively in both directions horizontally, and
is shaped as shewn to occasion a complete reciprocation of the said carrier in
each complete vertical movement of the cam up or down. Thereby, each time
the moving griffs pass each other at an intermediate point in their vertical tra-
verse, the carrier with the press-back wires mounted therein is moved toward
the right so as to carry the disengaged hooks of the uprights out of the path of
movement of the ascending griff-blades.
The ends of the press-back wires or needles 13, 13, at the left in Figs. 11,
12, and 13, of the drawings are inserted into horizontal holes in the cross-bar 33.
The right hand ends of the said wires 13, 13 are bent to form eyes through which
are passed the stems of pins 39 entering vertical holes that are provided in the
said cross-bar. This manner and means of applying and connecting the press-
back wires 13, 13, to the cross-bars 33, 331, provides conveniently for the support
and retention of the said wires in the carrier, and facilitates the application and
removal thereof.
To each slide rod 35 of the carrier is applied and made fast a collar 40, the
said collar being located at or near mid-length of the said slide-rod. This collar
is formed or provided with an arm or lug as 41, and to the said collar and arm
or lug a vertical strip 42 is affixed, as by means of a bolt 43. To the depending
portions of the strips 42 are secured the opposite ends of a bar 44 extending
crosswise of the machine, immediately below the press-back wires or needles 13,
13, and parallel with the cross-bars 33, 331. The press-back wires or needles
rest upon the upper surface of this cross-bar 44, or else are located normally
immediately adjacent to such surface, so that the said cross-bar constitutes a
stay or support for the intermediate portions of the said wires or needles.
Pins 45, 45 are driven into the top of cross-bar 44, between the press-back wires
or needles 18, 18, to separate the latter from one another, and restrain them from
transverse or side movement. The said pins are headed, and the heads thereof
serve to keep the press-back wires or needles from rising away from the cross-
bar 44. The said cross-bar, or intermediate rest, as it may be termed, recipro-
cates horizontally in unison with the carrier and the press-back wires or needles,
it being in effect a part of the carrier. During the operation of the Jacquard
mechanism having the present invention applied thereto, the rising and falling
of the uprights 3, 3, produces sufficient friction where they make contact with

page_text: the press-back wires or needles to tend to keep these latter continually jumping,
and this would occasion unnecessary wear thereof if the jumping were not pre-
vented. The intermediate rest 44, with its headed pins 45, restrains the press-
back wires or needles from unnecessary movement, either sidewise or vertical.
Preferably, the pins 45 are of the character or construction known as split, or
spring, or cottor-pins, as shewn clearly in the drawings, and this facilitates their
application to the rest 44, or their removal therefrom, rendering such removal
and subsequent replacing of the said pins convenient and easy whenever the
press-back wires or needles require any attention.
The press-back wires or needles 13, 13, are formed or constructed as will now
be described. The drawings shew two rows thereof; one row being located
immediately above the other. Each wire or needle 13 is formed with a succession
of half-eyes therein as at 131, 131, for the reception of the prolongations of the
uprights above the upper hooks 31, 31, of the latter, these half-eyes being for
example, of semi-circular shape as shewn. Two wires or needles are used in
conjunction, one thereof being located immediately above the other, the said
wires or needles being turned so that their half-eyes face in opposite directions,
as shewn, whereby each of such wires or needles serves to retain the limbs of
the corresponding series of uprights in the half-eyes of the other of such wires
or needles. This use of wires or needles in pairs, and formed with half-eyes,
enables me to avoid the use of wires or needles having round eyes, as usual
heretofore in Jacquard mechanism. The wires or needles with half-eyes are
cheaper to make, are much more easily and conveniently put into the machine
and taken out again, and have no objectionable features in operation.
Fifthly. My further improvements are shown in Figs. 16 and 17, the former
being a side elevation of certain portions of a double action Jacquard machine
having certain embodiments of my invention applied thereto, only such old parts
being shewn as are necessary in order to make clear the relations and mode of
operation of my new devices. Fig. 17 is a view in transverse vertical section of
Fig. 16, shewing certain of the parts which are represented in Fig. 16.
Each engagement of the cam and roller, (this engagement occuring each time
the two moving griffs are about to pass each other,) occasions a movement of
the carrier and press-back wires to the right in the drawings. This operates to
carry toward the right, also, clear of the ascending griff-blades, all the hooks
which are not in engagement with moving griff-blades. Those limbs having the
hooks thereof engaged with such griff-blades will ordinarily bend under the pres-
sure which is exerted against them by the press-back wires or needles, and it is
not intended that the hooks of such limbs should become dislodged from the griff-
blades on which they are seated. However, in order to guard against the
liability of such dislodging, I provide in connection with the uprights springs
which shall yield under the pressure of the press-back wires or needles, thereby
relieving the strain at the hooks which would tend to dislodge the same from
the griff-blades. This is effected very conveniently by providing the limbs of
the uprights themselves with springs located between the points at which the
hooks are formed or provided on such limbs and the points at which the press-
back devices take bearing against such limbs. The said springs may be formed
variously, and are of such strength that so long as the hooks of the uprights are
disengaged from the griff's the springs shall not yield under the pressure of
the press-back devices, the latter and the uprights operating the same as if the
springs were not present. However, a hook being engaged with a moving-
griff-blade, the action of the press-back devices against the upright occasions a
yielding of the spring, thereby relieving the hook from strain which might
operate to dislodge the same and obviating the tendency to the production of
faults in the weaving. In the drawings I have shewn the springs produced
at 333, 333, just above the hooks which engage with the moving griffs by
flattening the uprights for a portion of their length.

page_text: Sixthly. My invention here has reference more particularly to the springs
referred to in the fifth part of this specification and consists in interposing such
springs between the wires or needles and uprights, and which springs are intended
to yield under the pressure of the press-back wires or needles and thereby relieve
the strain at the hooks which would tend to dislodge the latter from the griff-
blades.
Fig. 18 of the drawings shews in side elevation certain portions of a double-
action Jacquard machine having my invention applied thereto, only such old
parts being shewn as are necessary in order to make clear the nature and mode
of operation of the invention. Fig. 19 is a view mainly in transverse vertical
section shewing certain of the parts which are represented in Fig. 18. Fig. 20
is a partial plan.
The best arrangement of the said springs which I have yet contrived is illus-
trated in the drawings, in which latter the springs themselves are designated 134,
134. They are each in the form of a narrow elongated and are mounted with
their free extremities extending downward as shewn. The said springs are hung
upon cross-rods 135, 135, supported by side-bars 1836, 136 made fast to the carrier
for the press-back wires or needles, or the said springs may conveniently be hung
or supported in any suitable manner. The two ends of each spring are intro-
duced, together with the upper end of one limb of an upright into one of the
elongated eyes 137, of one of the wires or needles 13. The expansion of the
spring within the said elongated eye holds the said limb pressed up against one
end of the said eye. When the carrier and with it the said wire or needle 13
is moved in manner as described above toward the right, the pressure that is
transmitted from the wire or needle through the spring 134 to the limb of the
upright bears the said limb to the right, also, so as to tend to move the said limb
sufficiently to bear its hook 31 out of the way of the griff-blade which is adjacent
thereto. Should, however, the said hook 31 be in engagement at such times with
the said griff-blade, and moving in unison therewith, the said spring 134 will
yield and become compressed under the resistance which the limb of the upright
offers to being moved laterally and thus the strain exerted against the said limb
will be relieved, so that the said hook will not be forced off the griff-blade. The
wires or needles 13, 13, are formed in the present embodiment of my invention
of flat metal strips, each punched with a number of elongated eyes 137, 137.
The ends of said wires or needles are sprung into holes prepared therefor in the
cross-bars 33, 33, of the carrier.

above the hooks thereof, the moveable carrier supporting the opposite extremities

page_text: of the said wires, and means to actuate said carrier whereby to move the same
transversely in the machine and thereby cause said wires to bear the uprights
laterally, substantially as described.
15. The combination with the uprights, and the oppositely moving griffs, of
the press-back wires to prevent engagement of a descending upright with an
ascending griff, the carrier engaging with the opposite extremities of the said
wires and provided with a rest to restrain the intermediate portions of the said
wires from movement through their engagement with the uprights, and means to
actuate said carrier whereby to cause said wires to bear the uprights laterally,
substantially as described.
16. The combination with the uprights, of the press-back wires engaging
therewith, the carrier engaging with the opposite extremities of the said wires,
the rest mounted on the carrier and located at an intermediate point in the length
of the wires, and the pins applied to the said rest and holding the wires from
movement, substantially as described.
17. The combination with the upright, of the two wires each having the half-
eye to receive a limb of the upright, the said half-eyes facing in opposite directions
whereby each wire serves to hold the upright in the half-eye of the other wire,
substantially as described.
18. The combination with the double uprights, and the oppositely moving
griffs, of the press-back wires engaging with the stems of the respective limbs
of such uprights and operating to prevent engagement of a descending up-
right with an ascending griff, the carrier for the press-back wires, the spring
to move said carrier in one direction, and the cam and pin or roller acting
in opposition to the spring to move the carrier in the other direction, substantially
as described.
19. The combination with the uprights provided with springs to yield under
the action of the press-back wires and thereby obviate forced disengagement
of the hook of an upright from the griff wherewith it is engaged, and the
oppositely moving griffs, of the press-back wires to prevent engagement of a
descending upright with an ascending griff, the carrier for the press-back wires,
the spring to move said carrier in one direction, and the cam and pin or roller
acting in opposition to the spring to move the carrier in the other direction,
substantially as described.
20. The combination with the oppositely-moving griffs, of the uprights, and
press-back devices to prevent engagement of a descending upright with an
ascending griff, the said uprights provided with springs to yield under the action
of the press-back devices and thereby obviate forced disengagement of the hook
of an upright from the griff wherewith it is engaged, substantially as described.
21. The combination with the oppositely-moving griffs, of the uprights formed
with springs adjacent to the hooks thereof, and press-back devices engaging with
the said uprights and operating to prevent engagement of a descending upright
with an ascending griff, the uprights bending at the spring portions thereof to
obviate forced disengagement of the hook of an upright from the griff wherewith
it is engaged, substantially as described.
22. The combination with oppositely moving griffs, of the uprights flattened
adjacent to the hooks thereof to produce springs, and press-back devices engaging
with the said uprights, and operating to prevent engagement of a descending
upright with an ascending griff, the uprights bending at the flattened spring
portions thereof to obviate forced disengagement of the hook of an upright from
the griff wherewith it is engaged, substantially as described.
23. The upright having a hook for engagement with an actuating griff, and
having the stem thereof adjacent to the said hook constructed with an elastic
portion of increased flexibility to permit the bending of the stem substantially
as described.
24. The combination with the oppositely-moving griffs, the uprights, and the
press-back devices to prevent engagement of a descending upright with an

page_text: ascending griff of springs interposed between said press-back devices and the
uprights, to yield and thereby obviate accidental disengagement of an upright
from a griff-blade on to which it is hooked, substantially as described.
25. The combination with the oppositely-moving griffs, the uprights, the press-
back wires or needles, and actuating devices for such wires or needles, of springs
interposed between the wires or needles, and the uprights to yield and thereby
obviate accidental disengagement of an upright from a griff-blade on to which
it is hooked, substantially as described.
26. The combination with the oppositely-moving griffs, the uprights, the
press-back wires or needles having elongated eyes receiving the limbs of said
uprights, and actuating devices for such wires or needles, of the springs also
entered into said elongated eyes and operating to yield and thereby obviate
accidental disengagement of an upright from the griff-blade on to which it is
hooked, substantially as described.
27. The combination with the oppositely-moving griffs, the uprights, the
press-back wires or needles having elongated eyes receiving the limbs of such
uprights, and actuating devices for such wires or needles, of the U-shaped
springs having the extremities thereof also entered into said elongated eyes
and operating to yield and thereby obviate accidental disengagement of an
upright from a griff-blade on to which it is hooked, substantially as described.
