This invention relates to a new mechanism for automatically controlling the
position and moving the fabric frame of embroidering machines, and consists of the
new combinations and arrangements of parts that are hereinafter more fully
described and pointed out in the claims.
The main object of my invention is to produce the various motions of the fabric
frame of an embroidering machine by the use of fewer pins than have hitherto
been employed for this purpose. In the prior art, so far as I am aware, there has
been used a separate Jacquard pin for obtaining each motion, that is to say one pir
would give, say, unit motion in a given direction; another pin two units of motion

page_text: in the same direction; a third pin three units of motion in the same direction; and
So on up to the desired number of motions; so, therefore, if we wished to give the
fabric frame three units of motion in a certain direction, we would pick out, by
means of the Jacquard card, the third pin. This necessitated a great number of
pins, as, if it were desired to give the fabric frame a range of 100 units of motion
in both directious, it would be necessary to have a set of 100 pins for imparting the
ne hundred increments of motion in one direction and a set of 100 pins for giving
one hundred increments of motion in the other direction.
It will thus be seen that in the mechanisms of this class heretofore used, a great
number of pins were necessarily employed in order that many different ranges of
movement might be given to the fabric frané.
Now, by my invention I dispense with the use of a great number of pins by
arranging the fabric frame in combination with mechanism, which enables different
pins to each give different extents of motion to the fabric frame on one and the
same line, and by actuating a plurality of pins and causing these pins to add or
subtract their motions, as will be more fully hereinafter set forth. For instance,
suppose we have a pin that is capable when actuated of giving to the fabric frame
seven units of motion on a certain line in the plane of the fabric frame and another
pin which is capable when actuated, of giving to the fabric frame eight units of
notion on the same line as the first mentioned pin. Now, if we wish to give to the
fabric frame seven units of motion or eight units of motion on the given line, we
actuate the corresponding one of these two pins, and if we wish to give fifteen units
of motion we actuate both of these pins, at the same time actuating other mechanism
which will cause these two pins to add their respective movements, in order to
produce the fifteen units of motion on one liue. Similarly, if we desire to give the
fabric frame one unit of motion on the given line, we actuate the same two pins at
the same time actuating other mechanism which will cause the said two pins to
subtract their motions, giving, instead of the sum, as in the former case, the
difference of the two motions, that is to say one unit of motion.
Therefore, broadly speaking, the essence of the invention consists in providing a
limited number of pins which will each serve to impart to the fabric frame different
degrees of motion on one and the same line, and selecting two of these pins and
combining their respective movements in order to obtain a movement of the fabric
frame on the given line, which will be the resultant of the movements which would
ordinarily be imparted to the fabric frame by either of the two selected pins acting
singly.
It will of course be understood that I also combine with these pins mechanism
for determining whether the movements shall be the sum of the respective
movements imparted to the fabric frame by the two selected pins, or the difference
thereof, thus further simplifying the machine.
To some extent the mechanism which I shall proceed to describe may be employed
in connection with the cross guides that are described in the Patent of the United
States of America No. 283,707 of August 21st 1883, as will more fully appear in
the later part of this Specification. But my present improvement can also be
employed in combination with means other than those specified in my aforesaid
Letters Patent for transmitting the desired movement to the suspended embroidery
frame:
With reference to Figure 4, Sheet 4, of the drawings, the letter A represents
the fabric frame. This frame A is intended, so far as this Specification is
concerned, to be understood as the same structure as the frame A shown in
Figure 1 of the said Patent No. 283,707 namely, a fabric frame properly
suspended, as shown in Figure 1 of that Patent, so as to be fairly balanced and
easily movable up or down, or in the direction of its length, in the plane of its
suspension, and is, as is likewise shown in Figure 1 of said Patent, and as is indicated
in Figures 15 to 18 inclusive, Sheet 11 of this present application, provided with
an extending arm a which has friction rollers or blocks that enter grooves in two

page_text: guides B and C which are represented as crossing one another at right angles.
These guides B and C, shown in Figures 15 to 18, are. the guides a and b of
Figures 1 and 14 of the aforesaid Patent No. 283,707. The guide B is rigidly
connected to a rack d and the guide C in like manner is rigidly connected to a
rack e, as clearly shown in Figure 16, Sheet 11. The rack d engages with a
pinion on a vertical shaft D and the rack e engages a pinion g on a vertical
shaft D (Figure 7, Sheet 7).
The reader of this Specification will have to understand that it is the object of
this invention to so revolve the shafts D and D* by mechanism controlled by a
Jacquard card E (see Figure 1) that the suspended fabric frame A, after each
stitch, shall be moved in the desired direction up or down or lengthwise in the
plane of its suspension, so as to present a particular new spot in the fabric to the
needles for the obtainment of the requisite design. It is, of course, not necessary
here to describe the machinery for operating the needles. The needle carrying
frame, or, as we may call it, the needle bar, is given a transverse movement after
every adjustment of the fabric frame A so as to cause the needles to pierce the
fabric at the desired place. But this invention does not concern itself with any
particular mechanism for controlling the needles or actuating them, as long as it is
understood by the reader that the needle frame moves, without any longitudinal or
vertical adjustment, on a certain track, whereas the fabric frame is to be adjusted
according to the Jacquard card in such manner that every new stitch shall be
placed exactly where needed for the production of the design; and it is likewise of
interest to understand that the invention relates mainly to machinery in which a
large number of needles is used simultaneously in the same fabric that is carried
by the fabric frame for the production of Hamburg-edgings or analogous multiplied
embroidery of like design.
By reference to the former Patent No. 283,707 it will be understood that when
the inclined guides or crossing guides B and C, which are shown in Figures 15
to 18 of this application, are properly moved, the required adjustment of the fabric
frame is obtained. They may be moved one at a time, or both together, as was
described in the above mentioned Patent, and, consequently, with reference to the
present invention, it is needful to so construct the mechanism intervening between
the Jacquard card E and the shafts D, D³, (see Figure 1, Sheet 1,) that, at the
proper time, each shaft shall be turned in the precise direction required to the
specific extent required, and that, after having been moved for thus adjusting
the fabric frame, each shaft shall be locked and rendered immovable while the
stitch is being produced. Inasmuch, therefore, as it will be necessary to revolve
each of the shafts D, D2, or turn it once in one direction, and at other times in
another direction, it follows that four means of turning said two shafts must be
used, namely, one for turning one shaft to the right, another for turning the same
shaft to the left, a third for turning the other shaft to the right, and a fourth for
turning this other shaft to the left. These four devices, in accordance with the
present invention, are: two double racks which, in manner hereinafter described,
enter into engagement with the shafts D, D', and turu each of them in the desired
direction from time to time. But, as will hereafter more fully appear, it is also
necessary to turn the shafts D, D, with varying speeds from time to time, and for
the obtainment of these different speeds I have, in connection with certain differential
gearing, which I shall also hereinafter describe, added two further double racks,
one for each of said shafts D, D2, so that with the aid of one of these racks the
shaft to which it pertains may be turned less far than when brought in gear with
the other of said racks, as will be more clearly described. It follows that we have
four racks with the aid of which to move the two shafts D and D'. The Jacquard
card is punched with reference to the existence of these four racks. Now, it also
follows that if any one of these four racks which is thrown into action is moved
further, it will turn its shaft D or D2 further than if the same rack is moved less
far. For the purpose of this Specification, and as a matter of convenience, I have

page_text: found a division of stroke into seven parts to answer the purpose; but, of coure,
any
other division into less or more than seven parts for the lengths of strokes
might be adopted.
These four double racks, which are indicated in Figures 7 and 8 of the drawing,
are so arranged that two of said racks, being the lower two shown in these figures
and being those marked J J', will affect the shaft D and pinion, while the other
two of said racks, being those marked J, J³, are intended to effect the motion of
the shaft D and of its pinion g. In other words, by horizontally reciprocating
either one of said racks, a corresponding degree of motion in the desired direction
is imparted to the proper pinion, the arrangement being such, as will be hereinafter
described, that the two double racks pertaining to the same pinion, for g, may be
moved to turn them in opposite directions, if necessary, at the same time, so as to
obtain for the said pinion the difference resulting from such motion in opposite
directions. All of this will be more minutely hereinafter described. I have stated
introductorily the general plan of mechanism for imparting motion to the fabric
frame A, but I shall now proceed to describe, starting from the Jacquard cards,
how the parts are arranged, which, when affected by said Jacquard card wilÍ
ultimately result in imparting to the pinions f, g, the precise extent and direction
of movement prescribed by the said card. Referring now to Figure 5, Sheet 5,
which is a vertical section on the line 5-5, seen on Sheet 6, we notice that the
Jacquard card E moving in a step-by-step motion to be explained herea ter, passes
around a pertion of a guiding cylinder E' and then around the card drum E2.
This drum is best seen in Figures 44 and 45, Sheet 16. It consists of a number of
straight bars, ex, arranged in such a manner as to form a cylinder or drum (see
Figure 3, Sheet 3). These bars ex are set in notches in the periphery of two
disks, e, at equal distances apart and parallel to the axis of the cylinder. The
disks are arranged so as to divide the drum into three parts, the central being
much the longer and the two extremes equal and much shorter. These dividing
disks carry projecting spurs which mesh with certain corresponding holes in
the guiding cylinder E', as also seen in Figure 3, Sheet 3. I have shown the
cylinder and drum E2 of about the same diameter and having the same number
of holes and spurs, respectively, but the relative diameters of these two parts may
he in any ratio, the former merely acting as a guide to the card E, and may have
any number of holes, provided their distance apart may be such as to cause them
to mesh properly with the spurs e. The office of the spurs e² is to properly mesh
with holes in the Jacquard card E so that the perforations in the card may always
coincide with the space between the bars ex of the drum E². The disks e' ure
secured to an axle e (Figure 44), which is rotatively hung in oscillating hangers E*
and E', which are rigidly fastened to a rock-shaft E', best seen in the rear view
Figure 3, Sheet 3. This shaft E° moves in bearings in the housings of the machine
and is rocked in its said bearings by suitable mechanisın. For this purpose it may
carry (Figure 6, Sheet 6) a crank E', which is connected by a link E8 (Figure 6)
to a suitably formed rotating cam on main driving shaft 1, Figure 3. This cam
imparts an up and down movement to the link Es, which in turn imparts a rocking
movement to shaft E, which in turn gives a swinging motion to the hangers E
and E, thus giving a similar swinging movement to the card drum E².
Referring again to Sheet 16, in Figure 44, it will be seen that the regular radial
arrangement of the bars or slats ex of the drum E produces longitudinal slots or
spaces into which the Jacquard pins can enter without friction, provided no
intervening obstacle is interposed between the ends of pins and the openings in
the drum.
The card E is punctured with reference to these slots in the drum and to the
position of the Jacquard pins h, so that pins which are to remain stationary will,
on every forward stroke of the swinging drum, be freely permitted to enter the
holes in the card and the slots in the druin, whereas those pins h which are to be
moved will encounter an unperforated portion of the card.
The inner or front ends of the pins h (Figure 5) abut against a corresponding

page_text: number of slides i which are confined in stationary guides,,,, which allow
fa free horizontal movement in a direction perpendicular to the axis of the
drum E. In the upper part of each slide i is a recess which engages the
downwardly bent end of one of a series of wires 1º. Each wire is thus enabled
to connect with one of the slides i, and is partly guided in the guide. The
wires connect by hooks or otherwise flexibly the slides with an equal number
of slides j, which slide in ways cut in stationary rods, but so as to admit of
two movements of j, one the horizontal backward and forward movement corre-
sponding to that of the slide i, to which it is connected, and the other a vertical
rotary movement of the front end of j around a movable point in its rear end,
which in the present case is the centre of a circle of which the two arcs 10 and ju
form a part. The front ends of the slides j are loosely held between pins which
serve as guides for the front ends of these slides. These pins & are fastened in
pairs, one above and the other below each slide to slides k, which are made in the
shape of an L, and are confined in stationary guides k', k², k³, kª, in which are cut
ways that admit of a vertical movement only.
On the horizontal portions of these slides k are hung by means of jaws which
loosely clasp them (see Figure 5) sliding hangers 4, to which are fastened vertical
rods k, which in their turn are fastened to and support sliding locking bars ;
28 of these bars slide vertically in ways go which are formed integrally with the
vertical sliding frames G1, G2, G³, Gʻ, G³, Gʻ, G7, Figure 6, Sheet 6, and which
serve the double purpose of acting as ways for the sliding bars 8 and as guides for
the horizontal rods m, m³, m², and m³. The remaining + locking-bars k³ connect
with a fixed block Go hereinafter described.
Referring to Sheet 7, Figure 7, we see these same rods m, m³, m², m³ again
fastened to horizontal sliding frames 1, 1, 12, 13, shown in vertical section in this
figure. A plan view of one of these horizontal sliding frames is seen in Figure 9,
Sheet 9, this figure showing said frame as fastened to eight rods m³, which latter
form the connecting links between a corresponding number of locking-bars k
and said frame 13. The other sliding frames 1, and connect also each with a
set of eight such rods, m, m³, m² respectively. Hence there are shown four
frames or slides 1, 1, 113, connected to 32 rods m, m³, m², m³, and by them to
32 locking bars 8, slides k and slides j. Of these 32 slides j, 28 connect with
28 Jacquard pins h, the remaining 4 slides j being otherwise connected as herein-
after stated.
In Figure 6, Sheet 6, which is a broken plan view of that part of my machine
shown in vertical section in Figure 5, Sheet 5, it will be seen that there are seven
vertical sliding frames G', G', G³, G, G³, G, G7. These correspond to the seven
divisions of stroke to which I have previously alluded. Each of these frames
slides horizontally in well-finished ways placed above and below it as in Figure 5.
The upper of these ways are formed on a plate X which has seven slots g³ (Figure 6),
through which the rods k' pass, 4 being in each slot. The seven slots y are of
varying lengths as indicated in Figure 6 to provide for the seven progressive
movements that are to be given to the seven slides G¹, G³, G³, Gʻ, G', G, G².
In Figure 3, Sheet 3, we see a rear view on a smaller scale of these vertical
slides G, &c. These slides are respectively connected by links 9', I³, 9³, 9ª, 9′, 9ª
and g' to a triangular shaped bell-crank lever H, the lower arm of which holds
a friction roller, which works in a rotating cam, H, which is mounted upon the
main shaft I. The upper arm forms a right triangle, upon the hypothenuse of
which we see a series of seven steps, upon which are. formed seven bearings for
the rear ends of the seven before mentioned links. This crank lever H is
rotatively mounted in bearings H³, H', which are hung to the main frame. The
distances of the bearings upon the steps from the axis of rotation of H are in
arithmetical progression from 1 to 7, the "1" representing the unit stroke before
mentioned, and the other terms of the progression representing the other six
strokes.
Now, returning to Figure 5, Sheet 5, we see a side view of the upper part of the

page_text: lever H showing the seven bearings on the steps and the seven links g',g', g³,9', 0°,9*
and 97, which connect the lever H with the vertical frames 'G' to G inclusive,
only one of which, G', is seen in this figure, because I have here shown these
frames in their forward position in which their ends all lie in a vertical plane
parallel to the rotating axis of the lever H.
When the lever H is moved by means of a cam to the position shown by dotted
lines in Figure 5 it will draw after it the seven vertical slides, but each slide will
move through a distance equal to the chord of the are described by its point of
connection with the lever H, and will thus be brought into their respective
progressive positions shown by dotted lines.
In Figure 6, Sheet 6, it will be seen that there are eight rods marked m³. In
Figure 5, Sheet 5, only one of these rods m³ is shown; but it must be remembered.
that in this figure m³ represents a horizontal group of eight such rods all connected
to one horizontal sliding rack frame. In like manner m, m' and m² represent
horizontal groups of eight rods each, each group being fastened to a similar
horizontal frame. Thus we have four groups of eight rods each connected to
four horizontal sliding rack frames, and each of these frames controls the longi-
tudinal motion of one of the four double racks before mentioned.
Referring to Figure 9, in these rack frames 1, 1, 1, P, the latter of which is the
only one seen in full (it being the upperinost), we see inwardly projecting brackets /
upon which are finished ways or guides . At the rear end of the frame, and
opposite to , are two other finished guides formed on said frame. Sliding in
these ways is a double rack J³, the two sides of which are joined rigidly by a
connecting bar J underneath their rear ends, which in the present case is cast
integrally with the racks, and is shown in elevation in Figure 7, Sheet 7.
The rack frame has finished edges which fit and slide in finished ways in the
stationary frame only, as shown by cross-section in Figure 8, Sheet 8. This.
description of the rack frame will substantially fit the other rack frames 1, 1
and which control respectively the movements of three other double racks J, J
and J. The lower of these racks J and J' have their connecting bars J* in front.
as in Figure 7, and the brackets for these lower racks face forward instead of
backward.
The two upper racks J' and J³ control the movements of the pinion g on shaft D'..
The two lower racks J and J' control the movement of the pinion on shaft D.
The pinions and g, Figure 7, Sheet 7, are made integrally with the shafts D
and D, respectively, though they may be made separately and fastened to their respec-.
tive shafts. I have broken away the housings of the shaft D', exposing its pinion g.
In Figure 8 we see a stationary bracket, d', on which is cast an upwardly projecting
hub, d, and a downwardly projecting hub, D. In these hubs or tubular housings.
the shaft D is by preference held. I also prefer to use a bushing, d, driven into
hub D and held in place by a screw, d, or otherwise. On the upper end of the
hub is a shoulder, d, which forms a support for a rotating frame, De, which
contains in its lower part, within a yoke formed integrally therewith, a train of
differential gears, dª, d³, dº, d², to be explained hereafter. The wheel ‹* is fastened
rigidly to the upper end of the shaft D.
The wheel is fastened to the lower end of a shaft, D', which is aligned with
the shaft D as shown, and which is supported in a stationary hub, D, which is.
carried by a cross-bar, D", of the main frame.
The shafts D and. D' are connected only by the train of gears d*, d³, d³, d², in
which train d and d are made integrally of one piece of material, or otherwise
fastened rigidly together.
The office of this train of gears will be more fully explained in another part of
this Specification.
Upon the upper part of the rotating sleeve D, Figure 8, is a spur wheel D' and.
upon the shaft.D is fastened a spur wheel D8 and further up on the same shaft
another spur wheel D, all as shown in Figures 7 and 8.
The above description of the shafts D' and D', with their bearings and mountings,.

page_text: applies similarly to the shaft D and its fellow D³. The spur wheels D' and Dª are
made to mesh with the racks J, J', respectively, whilst on the other shaft D³, the
spur wheels D and D are made to mesh with the racks J and J, respectively.
The sleeve D corresponds to the sleeve D, the wheel D" to the wheel D'. The
sleeve D has also a yoke containing a train of gears in every particular like the
sleeve and yoke D, with its train of gears d', d³, d' and d'. Hence the shafts D³
and D' will, when revolved, communicate motion by these gears to the shafts D
and D', and thereby to the racks d and e.
Referring to Figure 9 again, we notice below the rack frame a narrower trans-
verse frame L', whose office is to mesh, to shift and to unmesh the rack J³ with
and from its spur wheel D³. This frame, which we will call a meshing bar, slides
on finished edges L in grooves cut in the housings. Two projecting brackets L°,
at right angles to the length of the bar, form guides and supports for the rack J³,
as clearly shown in Figures 7, 8 and 9.
Three meshing bars, L, L', L', which guide and support the racks J, J', J',
respectively, are like the meshing bar I just described, except that bars L and L'
have the supporting brackets nearer the front, whilst the bars L' and L' have their
brackets nearer the rear. By reference to Figures 7 and 9, we see between the two
shafts D and D, extending downwards through bearings cast to cross bar D", two
smaller shafts, K³, K, of unequal lengths. Upon shaft K³, which is the longer of
the two, are two pawls K, arranged to engage the two spur wheels D and D".
Upon the shaft K are two pawls K2, which are arranged to engage the spur
wheels D' and D. The upper ends of these shafts, K, K, see Figure 10, Sheet 10,
are provided with cranks K, K, respectively, which at their ends farthest from their
respective shafts engage an actuating link K7. This link K' has its rear end
connected to a lever, which carries a friction roller playing in a rotatory cam, as
indicated in Figure 1. This cam is mounted upon the main shaft I, in such relation
to the cam that operates the meshing bars L, L', L, L³, that whenever the racks
are unmeshed the pawls engage, and vice versa. It will be explained further on that
the racks are either all engaged or all disengaged; one or more cannot be engaged
whilst the others are free. This is also true of the pawls, whose office is to
immediately engage the spur wheels as they are disengaged from the racks, so as to
hold them in proper position to be engaged without interference when necessary.
A certain train of gears, D, D, D1, D18, which I will now refer to, is to be
used when the machine is at rest, and it is desired to arrange my attachment to
begin work.
It must be remembered that the object of my invention is to so move the fabric
frame back and forth before the embroidery needles that the latter will make
successive stitches upon the fabric such as would be made by hand by one skilled
in embroidery.
There must be a starting point in the figure to be worked, and in order to set
the fabric frame at any desired point of the pattern a band-operating device is
necessary. This device is shown near the front of my attachment in Figure 2,
Sheet 2, and in detail in Figures 7, 8, 10 on Sheets 7, 8, 10 respectively and
Figure 11 on Sheet 10.
The shafts D and D', it will be remembered, indirectly operate the racks d
ande (Figures 15 to 18, Sheet 11), which in their turn operate the inclined
guides B and C, which in their turn move the fabric frame A in a direction which will
be the resultant of the two motions imparted to A. by B and C working separately or
together. When my attachment is driven by power applied to the main driving
shaft I these two guides B and C move at the same time with any desired speed
unless only one is required, in which case the mechanism which operates the idle
guide is locked and immovable. But when the fabric frame is to be moved by hand
through the agency of these guides it is found best to move the two guides together
with the same speed, either in the same or in opposite directions. When moved in
the same direction at same speed the fabric frame is moved. horizontally. When
moved in opposite directions at same speed the fabric frame is moved vertically.
"

page_text: Thus by these two motions successively applied, the fabric frame may be brought
to any desired position. For this purpose we provide the shafts D³, D', with spur
wheels D, D, respectively, both of same size. An idle spur, D, in the present
A smaller
case of the same size as Die and D is permanently in mesh with D".
spur, D, is rotatively mounted in a bracket bearing D, which in its turn is
rotatively mounted upon the upper end of the shaft D (see Figure 12, Sheet 10).
This bracket is so arranged that it may slide up and down on D between certain
limits. Two pins, D", driven into shaft D, confine a small crank, D", which
carries at its smaller end a dowel pin D", which passes through a boss on D", and
is held therein by a set screw. This dowel may rotate about the shaft D' within
certain limits, but may not move vertically, since it is held by pins D.
The spur D18 is fastened to the lower end of a small shaft or arbor which passes
vertically through the bearing D, and is held from falling by a collar D, which
is either driven on the arbor or fastened by means of a set screw. The upper end
of this arbor or shaft is faced off in the form of some regular prism to accommodate
one end of a removable crank-handle Dº.
Figure 11 is a plan view of this bracket-bearing D. The collar D, which
rotates with the spur I18, carries a pointer D2, which moves around a dial which is
divided into ten (more or less) equal parts. In the present case the spur D 18 is
provided with ten teeth, whilst the other three, D, D16, D", have each sixteen
teeth. The axis of D is always parallel to that of D, and the distance between
these axes is such that the pitch cylinders of the two spurs are always tangent
whether they are in or out of mesh.
The hand-driven pinion D18 when meshed with D" and D', as shown in Figure 10,
and then turned in the direction indicated by the arrow, will drive the shafts D*
and D in opposite directions and with them the shafts D and D3, thus moving the
racks d and e in the same direction and away from the embroidery machine at the
same rate of speed, which combined movements will cause the fabric-frame to move
horizontally in the same direction and to the same extent. By turning the
crank D in the other direction we will get a reverse movement of the fabric-frame.
When the hand-driven pinion D18 is in mesh with D and D", the two latter will
be driven in the same direction and consequently move the racks d and e in opposite
directions at the same rate of speed, thus causing the fabric-frame to move up or
down vertically, according as the crank D is turned to the right or left.
The pinion D18 before being lowered so as to mesh with D and either of the
other two pinions D1 or D should be 60 located that its teeth will slide
uninterruptedly between the teeth of the other two. To accomplish this easily
and surely it is necessary that in moving the bearing D about D it must only
move just far enough either way to bring the pitch cylinder of D18 to a position
tangent to that of the other pinion with which it is desired to mesh it. It must be
remembered that the pitch cylinders of D1 and D are always tangent, hence by
moving D18 till its pitch cylinder becomes tangent to either of the other pitch
cylinders, it makes its pitch cylinder tangent to the pitch cylinders of the two spurs
with which it is to be meshed.
In order to prevent D₁ from being moved too far in its arc, an arm D cast
integrally with D and having a hook-shaped extremity, which in the drawing
Figure 11, is in the form of a sector whose mean radius is the distance between the
centres of D and D* has secured to its upper surface a piece of metal di bent
downward at its two ends far enough to form two stops d" and dis for the horizontal
rotary movement of D. In Figures 11 and 12 the stop is seen to be in
contact with D³.
In this position a pin d" projecting downwardly from D is in such a position
that it will slip snugly into a hole bored in the top of the shaft D³, when D is
lowered for operating. Again when D18 is moved so as to be in position for
meshing with D and D the stop d" will reach contact with shaft D' and a
downwardly projecting pin d" will then be above the same hole in the top of
shaft D. There is a third pin d larger in diameter than, and situated midway
B

page_text: between, and d¹s which serves as a stop to prevent the spur D18 from falling
into any position save those two determined by the pins d and d and the
stops d and d¹³, because the pin de will be above the shaft D13 and prevent the
descent of the bearing D", unless one of said pins d or d arrives above said
shaft. The office of the dowel pin D" is to prevent the lifting of the pinion D18
and bracket D except when the gears D', D8, D", D" (Figure 7, Sheet 7) are in
proper position to be engaged by their respective double racks. This is shown by
the pointer D and dial upon D". When the pointer rests upon one of the radial
marks which are the same in number as the teeth of D', it is an indication that
the dowel D is in position to pass between two of the teeth of D18, allowing D18
to be raised after it has performed the desired adjustment.
It is evident from the description of this hand-operating device that the
shafts D and D* can only be turned through ares which are multiples of the ares
on the pitch circles from cne tooth to another of the spur-wheels D' and D
(which are equal). It is also evident that (referring to Figure 9, Sheet 9), since
the rack frames 1, 11, 12, 13, all must return to a normal position (which is that
shown in the figure) before the double racks can be again meshed to their respective
spur-wheels, these spur-wheels must always stop in position to be meshed by the
racks in the normal position. This can only be accomplished by making all the
rotary movements imparted to the spurs by the racks multiples of the ares on
the pitch circles representing the distance from one tooth to another.
The pattern to be embroidered, however, in nearly all cases, requires that the
movements of the fabric frame shall not be restricted to multiples of any one unit
of distance, but, on the contrary, requires the greatest variety of movements in
any direction and to any distance. This led to the introduction of the differential
gearing before mentioned so that the movements of the shafts D and D' in
multiples of a certain unit might be divided and subdivided so that any desired
distance in any desired direction might be accomplished by the fabric frame.
Before describing this differential gearing, however, I will return to the rack-
frames and show how they are connected to that part of the machine that is
operated by the perforated card E.
Referring to Figure 9, Sheet 9, we see that the rack-frame and likewise the
other three rack-frames below it, have extending horizontally from the under rear
surface eight bars m³. In Figure 5 these four groups of eight bars each are shown
in elevation, m³, m³, m², m, as passing between the lugs or ways 9, which serve as
guides and which are cast upon the vertical sliding frames G to G. Each of
these bars has near its rear end a hole marked in their respective groups n³, n', n³, n.
These holes in the normal positions shown in Figure 5 stand immediately over pins k
extending upward from the locking bars k³.
Let it be borne in mind that
below each group of these eight bars and below each bar of the group is to be
found one of these locking bars 8. When one of the vertical hanging rods k' is
lifted carrying with it its locking bar, the pink will enter the hole immediately
above it, locking its particular rack-frame to the vertical sliding frame intended.
I have spoken of groups of eight bars m, m³, m³, m³, whilst there are only
seven vertical sliding frames, G' to G', to give the seven grades of motion before
mentioned.
It is as necessary to provide for holding the double racks stationary as to give
them movement, hence the first bar in each group of eight is for locking its
particular rack to a locking bar which is horizontally stationary, moving vertically
in ways cast upon a stationary block seen partly dotted in Figure 6, marked Go.
On the outer side of G° will be noticed, dotted in, another group of four hanging
rods with their locking bars. This group is for regulating the meshing of the racks
to be explained hereafter.
It will now be evident why these vertical hanging rods k' are arranged in groups
of four, since each rod. in each group is to.govern some function of, or pertaining to,
one of four double racks. In addition to those nine groups of four each there will
be noticed two isolated hanging rods, one at each end of the phalanx.
These

page_text: rods 0, 1, Figure 6, have no locking bars attached, but extend downward through
holes in the housings to certain mechanisms which will be explained hereinafter,
and which are partly shown in Figure 1, and more fully in Figure 35, Sheet 17.
The rod regulates a shuttle-moving device of the kind commonly used in
embroidery machines, and operates to stop the embroidery machine and with it
my attachment. The shuttle rod 10 operates in the following manner :-
On the embroidering machine there are two cams for moving the shuttles. They
are different in shape and give the shuttles a motion suitable for various kinds of
stitches. Only one is in use at a time, and the cam roller connected to the bar
which directly works the shuttles may be changed or has to be changed from the
one to the other according to the movement that is required of the shuttles, and
the function of the shuttle rod 10 is to move the cam-roller out of one cam and into
the other.
Since the hanging rods k', Figure 5, are connected through the sliding hangers k
with the slides and j it follows, that since the hanging rods are arranged in groups
of four, the slides and will be arranged also in groups of four. And since there
are four double racks to be operated by the pins h, it follows that a division of
those pins and their slides into four groups will be the most convenient. This
scheme of grouping these pins and slides is clearly illustrated in diagram 43
Sheet 20. The slides are here shown divided into four groups of eight each with
two extreme slides isolated from the rest and marked "stop" and "shuttle "
because they operate the stop and shuttle mechanisms respectively. before
mentioned, whose actuating bars are vertical, marked " and 10. I have placed
near these four groups of eight (see right hand end Figure 43) the letters J, J', J², J³,
which are the same as appertain to the four double racks. Thus by analogy we
see that the first group of slides i controls the movements of rack J, the second
controls rack J, the third controls rack J', and the fourth controls rack J. I
have marked the individual slides in each group 1a, 1, 2, 3, 4, 5, 6, 7. The four
marked la control the meshing of the four racks, and those marked 1 to 7 deter-
mine whether the racks shall be moved 1, 2, 3, 4, 5, 6, or 7 units respectively. This
unit of movement is the distance between the centres of any two teeth on the rack.
So that in speaking of moving a rack three or more units is equivalent to saying
three or more teeth (or multiples thereof). We also see that the four slides i,
marked la, are connected with a group of four slides j, also marked la, shown in
the lower left hand corner; also-that the four slides i, marked 1, are connected with
four slides j', marked G (Fig. 43) that the four slides i, marked 2, are connected
with the four slides 2, marked G, and so on up to slides i marked 7, and slides.
marked G.
The group of four slides j, marked la, see Figure 6, is immediately over four
hanging rods k, that control the meshing of the racks. The group marked Go⁰,
Figure 6, is immediately over four hanging rods k' that lock the racks. It will be
noticed from the diagram, Figure 43, that these four slides j, forming the group
marked Go, are not connected to slides i like all the other slides, but are con-
Dected by wires (see Figures 5 and 6) to the upper arms of four levers,
which
are rotatively mounted on a horizontal axle, 0, which is held at its extremities in
the ends of two cranks, which are secured firmly to a rock shaft, which is
mounted in bearings in the housings or main frame, and carries on its outer end a
crank, which imparts to the rock shaft "n oscillating movement through a
small are by means of a link ¹ (see Figure 1), which is actuated by a bell crank 14,
which plays in a rotary cam on the main shaft I. The group of four slides j,
marked in the diagram, Figure 43, ƒª, is immediately over the vertical sliding
frame G', which has a reciprocating horizontal movement of one unit, and may be
connected to any one of the four double racks. Similarly the group of four slides j,
narked, is immediately over the vertical frame G2, which has a reciprocating
horizontal movement of two units, and may be connected to any one of the four
double racks. And so on, throughout the other groups of four slides j, it will be seen
hat each group is immediately over its respective vertical slide, thus providing

page_text: a means of connecting any one of the four double racks with any one of the
vertical sliding frames whose horizontal movements are in arithmetical progression
from 1 to 7. The slides į pertaining to group Go, connect with locking bars,
which have no horizontal movement. This last-mentioned locking of the racks
I have preferred not to leave to the action of the perforated card, and have not,
therefore, connected those bars with the slides i and pins h, but have connected
them, as explained before, to levers, whose action 1 will explain later on in the
Specification.
Two notches, j, j", Figure 5, Sheet 5, will be noticed in the slide j. Over the
notch is a bar M, which extends over all the slides j, and is held at or near its
ends by two cranks M' secured to a rock shaft M. Just touching the under
surface of near its front end, and hence all the other slides j, is seen another bar, M³,
which is held at or near its ends by two cranks, M, secured to a rock shaft M'.
These rock shafts, M, M, are mounted in bearings in the housings or main frame
(Figure 2, Sheet 2), and have secured to their outer ends cranks M6, M7, respec-
tively (Figure 1, Sheet 1), which are actuated by a T-shaped link M, which
receives a reciprocating movement in the direction of its length by a bell
crank M, which plays in a rotary cam upon the main shaft I. The cranks M6, M7,
extending in opposite directions, and actuated by the same link M8 will impart to
the shafts M M³, a rocking motion in opposite directions.
Referring again to Figure 5, this rocking motion will move towards and from
each other the bars M, M. The extent of this movement is indicated by dotted
lines.
In the upright part of and in the rear edge will be seen two notches 1, k.
These are in all the slides k. Into these notches fits a locking bar M°, which is
held at or near its ends by two cranks M10, which are secured to a rock shaft M",
which is rotatively mounted in bearings in the housings or main frame (see
Figure 2) and carries secured to its outer end (see Figure 1) a crank M, which
is pivoted to a link M", which receives a reciprocating movement in the direction
of its length by means of a bell crank M28, which plays in a rotary cam on the
main shaft 1.
Referring again to Figure 5, Sheet 5, we notice on the upper edge of the front
limb of slide two V-shaped notches o, o¹, and another V-shaped notch which has
its front incline, o³, longer and extending higher than the others. This forms an
incline near the upper part of which is seen to be nearly touching it the lower edge
of the lever before mentioned. This lever is made long enough to engage all
but one of the slides i of each of the four groups of eight shown in the diagram.
The four slides of these groups that are not engageable by these levers are
marked la (in Figures 6 and 43). The reason for omitting these four slides from
engagement with the levers will be understood later. Directly over the notch o
will be seen the cross section of a rod O, which extends over all the slides i, and
is shaped to fit in the notches o' and o. This rod O is for holding the slides
firmly in their proper places. The rod O is held by arms O¹, which are secured
to a rock shaft O' which is rotatively mounted in bearings in the housings or main
frames (Figure 6), and carries, secured to its outer end, a crank O³ (see Figure 20,
Sheet 13), which extends in an upward direction and is pivoted to a horizontal
bar whose rear end is provided with a slot O' which slides over a pin P.
This pin P is seen to be secured in the end of a semi-circular lever P. This
lever is secured (see Figure 23, Sheet 14) to a shaft P, which is rotatively mounted
in the housings. I will explain the office of this shaft at another place. For
the present it is best to consider the semi-circular lever P7 (Figure 20, Sheet 13)
as fastened to the housings aud kept from rotating by a pin P (see Figure 19,
Sheet 12) which passes through a boss P' on the lower part of P7 and into the
housings. Thus, it will be seen that the rear end of the bar 01 (Figure 20,
Sheet 13) is kept from falling and also from being lifted by a pin P.
A cam which rocks with a shaft Q, upou which it is mounted, plays in a
suitable notch O' in the bar O' (Figures 21 and 22), and, by reason of its deflected

page_text: form and oscillating movement, imparts to the bar 04 a reciprocating horizontal
movement. This movement rocks the shaft ()* (Figures 5, Sheet 5), thereby
depressing and raising the locking bar O when required. The manner of rocking
the shaft Q is hereinafter described. Loosely pivoted at the rear ends in the
swinging arms E' (Figures 5 and 6) are two stout wires 13, which slide through
holes in and are held from falling by the bar, which is mounted in the housings.
These wires carry a bar, which is secured to them. This bar is seen to be
nearly tangent to the upright limb of the slides, and being linked to the
swinging arms which carry the card-drum E2 must move with said druin.
l'assing through the bar and fastened to it at its rear end by a set screw is
seen a wire (Figures 5 and 6), which near its front portion slides through a
hole in a stationary bar . The front end of this wire carries a winged pawl,
which engages the four slides of the series G in recesses in said slides..
These are the slides which operate the locking bars k, which slide in the fixed
block G".
Referring to Figure 45, Sheet 16, we see secured by a set screw to the outer
end of the drum shaft e a crank e, which has at one end a handle e, which is
arranged to slide in the direction of the axis of drum in bearings in the crank.
This handle carries a spur on its inner end, which engages radial slots e' in a
stepping wheel E', which is loosely hung on the drum shaft e³. This stepping
wheel is held from rotating and is also given a step-by-step rotation by means
of a lever E, Figure 1, which carries a flat pawl Elf on its rear end, which
engages radial slots in the wheel E. This semicircular lever E is rotatively
mounted on a pivot E12 rigidly fastened to the housings, and is given an oscillating
movement by a link E, which is pivoted to a lever E", whose lower end plays in
a rotary cam on the shaft I. There is to the front of the stepping wheel E'
another flat pawl E", which is secured to the housings.
It will be noticed by reference to Figure 45, Sheet 16, that this stepping wheel
has as many radial slots (say 32) as the number of radial slots in the card-drum,
but that only half this number extend entirely through the thickness of the wheel.
Referring to Figure 1 it will be seen that the drum E2 is shown in its backward
position with the stepping wheel engaged by the rear pawl E". In swinging
forward it will be seen that the stepping wheel will be engaged by the pawl E
before E has released it. The former pawl E1 being fastened to the housings,
prevents any possible rotation of the drum while in the forward position. The
step-by-step movement is imparted as follows: As shown in Figure 1, the
stepping wheel is free from the stationary pawl E" and engaged by the movable
one E. This latter by means of the link E13 and the rotary cam before mentioned
receives an upward movement about the pivot E, carrying with it about its own
centre the stepping wheel E' a distance equal to that between one radial slot and
the next. This will bring another slot opposite the pawl E, which will engage it
when it swings forward releasing E". E" then returns to its former position, the
drum swings back, engaging the stepping wheel again with E", which is thus
in position to repeat the former upward rotary movement.
"
The slack in the card is cared for by another roller e¹¹ of the same size as El,
though it may be smaller or larger, suspended above, and over which the card is
passed. This is clearly shown in Figure 42, Sheet 19.
Above the shaft E and near to it is a parallel one considerably smaller, carrying
Lear its ends two sprocket wheels e, which engage two sprocket chains e, which in
their turn engage two other sprocket wheels e, secured in some convenient position
to the ceiling above in such a manner, that the chains may remain always taut.
Somewhere in the length of these chains are inserted two bearings which carry a.
light axle on which is fastened the roller e". In Figures 1 and 3, on Sheets 1
and 3, respectively, it will be seen that the shaft E carries near its out end a
toothed wheel which engages a gravity pawl e, operated by hand, which prevents
rotation of the shaft E, and consequently its sprocket wheels with their chains.
Thus the roller el, Figure 42, Sheet 19, may be raised or lowered to any position

page_text: and held there by this pawl. This, it will be readily seen, provides a simple
method of taking up the slack of the card.
We now understand enough of the principal parts of my mechanisin to be able
to follow their various actions in succession as controlled by the perforations in the
Jacquard card. The explanations of various precautionary devices which have
been found desirable in connection with the proper working of my machine, and
which form a part of my invention, will be reserved for another part of this
Specification.
'
Referring to Figure 5, Sheet 5, we will suppose that there is only one perforation
in the card E and that one to be opposite the end of the sliding pin there shown,
so that when the drum E, carrying the card E swings forward by means of a
rocking motion imparted to the shaft E by crank E' (as explained previously, and
clearly understood by reference to Figure 6), the pin 4 will pass through the card
and into the drum, or rather the card will pass over the pin without moving it,
while all the other pins, with their slides and will be pushed forward.
j
It must
be remembered, however, that there are four slides (see diagram, Figure 43) that
have no corresponding pius and slides i; hence, these four slides j, in addition to
the slide operated by the card, will be left behind. Thus we have all but five of
the slides pushed forward assuming the positions indicated by dotted lines 1.
The slide shown in Figure 5 is the same that is numbered 1 in group J in the
diagram 43, Sheet 20. The slides i are then all locked firmly from further move-
ment by the rocking of shaft 03, thus depressing the locking bar O into the
notches o, o, according as the slides are pushed forward or remain behind. Next
the shaft is rocked, depressing the rod 10, which carries the wedge-shaped
lever . Now, since the slide i, as seen in the figure, is the only one remaining
behind, it is the only one that will engage one of the levers. The wedge end of
this lever will, on its descent thus be pushed backward by the incline o², thereby
pushing forward the upper end of the lever, the wire and the slide j, to which it
is joined. Thus we have only four slides standing in the normal position; all the
others occupying the forward position shown by dotted line 14. Next the locking
har M is withdrawn from the notches in the upright limbs of the slides k. Then
the shafts M and M' rocking in opposite directions, cause the bars M and M³ to
approach each other, carrying upward the four slides that are left behind, and
not disturbing those that were pushed forward. That is to say, the upwardly
moving bar M³ enters the notches 12 of the slides that have been moved forward,
and only lifts those slides whose notches are out of line. The extending bar M
simply serves as a jaw to receive the thrust of the ascending slides, and to help M³
hold all the slides in position. The slides; that have been lifted carry with them
the slides k, to which they are attached, together with the hangers 6, the rods
and their locking bars k.
In the figure the slide k, which is shown, will lift the lowest locking bar k³,
thereby locking the vertical sliding frame G¹ to the lowest rack frame, thus
.connecting it for the smallest (unit) movement.
By referring to the diagram, 43, it will be seen that the four slides į,. &c., that
have been lifted, I have caused to be marked by small semi-circles. It must be
remembered that the group of slides G are intended for locking the rack frames.
These slides are not operated from the card, but in a more satisfactory manner, as
will now be seen.
In the case when only one perforation occurs opposite the pin marked 1 in
group J that one slide remaining behind causes the first slide in group Go to be
pushed forward whilst the other three remain behind. This is as it should be, for
the card indicated that the lowest rack was to be used, and only the lowest; there-
fore, the lowest, and only the lowest should be free to move, all the others being
locked.
Again, suppose the slide marked 3 in group J' be left behind. This will actuate
the third wedged-shaped lever, thus unlocking the rack J', whilst all the others will
be locked. This slide marked 3 in group J₁ indicates that the double rack J¹ is to

page_text: be moved three units, therefore this rack is unlocked for the purpose, whilst all the
others are locked immovable.
Those levers which regulate the unlocking of the racks, engage with but seven
of the slides i in each group of eight shown in the diagram. This is because there
being seven positive motions, any one of which may be connected to one rack frame,
it follows that any one of the seven slides which control this connection should also
control the necessary unlocking for that particular group. Hence each lever
submits to the action of seven slides i and no more. The first slide la in each group
is to regulate the direction in which its particular rack is to turn the pinion with
which it is to be meshed. It is so arrangal that when there occurs no hole in the
card opposite one of those pins marked la the toothed wheels D', D, Du, D", will
be turned in a certain direction. When the hole does occur then the rotation will
be reversed.
This meshing of the double racks with one side or the other of their respective
pinions is accomplished in the following manner :
Referring to Figures 8 and 9, Sheets 8 and 9, respectively, we see pivoted near
the outer ends of the meshing slides L, &c., V-shaped links, F³. These links
have two limbs of unequal length set at an angle of about forty-five degrees and
pivoted at their junction to the meshing slides. Each limb forms on its inner face
a jaw, said jaws being adjusted to fit over pins F, F. There are four pairs of these
pins, one pair for each meshing slide, and they are carried in four tiers on opposite
sides of a vertical shaft, F (see Figure 13, Sheet 10), and are firmly fastened to
four horizontal brackets at equal distances from said shaft F. Two of these
brackets (Figures 8 and 13, Sheets 8 and 10, respectively) are firmly secured to the
shaft F, which rests in bearings in the housings and has secured to its lower end u
crank F (Figure 8). The other two brackets move with the shaft Fe in the same
way as if they were fastened to it. This will be explained more fully in another
part of this Specification. The end of this crank is pivoted to a link Fs (Figures 8
and 9), which is itself connected to a bell crank, F*, one end of which plays in a
rotary cam on main shaft I (see Figure 1), thus securing an oscillating notion to
the shaft F (Figure 9), and with it and about it to the pins F, F. If the
V-shaped links F are all connected to the pins F, as in Figure 9, they will,
when the shaft F is rocked by a pull on F, push the slides L³, &c., and their racks
over against the pinions, meshing them so as to give a rotation in a direction
contrary to the movement of the hands of a watch, when the racks thus engaged
are moved rearward.
To the rear limb of each of the links F, F, F, F (see Figures 1, 8, 46 and 47),.
are attached horizontal bars, f³, ƒ³, f¹, f. respectively, which bars are pivoted to
bell-crank levers, whose bearings are in the stationary castings G° before
mentioned (Figure 6). The lower arms of these bell cranks are provided with
slotted holes in which play horizontally projecting pins from four bars similar to
the locking bars in Figure 5 and similarly placed. These bell-cranks having.
their angles opposite (as in Figure 1), do not all move alike. The two lower ones
when actuated by the lifting bars k' will push their meshing links F toward the
front. The two upper ones when actuated in the same manner will pull their
respective links F³ to the rear. The normal position of these links is that indicated
in Figure 1.
Now, returning to Figure 9, we will see that if a rotation like that of the hands.
of a watch is desired the link F' must first be pushed to engage the pin F³,
after which the shaft F' must be rocked to move the pin F away from the
double rack.
Thus it will be readily understood how the perforated card may be made to
control any and every movement of the fabric frame within certain limits prescribed
by my mechanism.
I will now describe the actions of the train of differential gears introduced
between the upper and lower parts of the rack-driven and rack-driving shafts.
Referring to Figures 7 and 8, we see that there are two spur wheels of the

page_text: .
same size and gearing firmly fastened to the vertical shaft D. The upper of these
spur wheels, D, is for operating by hand, as before described. The lower one, D³,
is intended to be meshed with the double rack, J. The lower end of this shaft, D,
has attached to it a larger toothed wheel, d'. This wheel has 75 teeth, which
engage a pinion, d, which has 20 teeth. This pinion is rigidly fastened to and
immediately above another pinion; d, on the same shaft, which has 19 teeth. In
the present case these two pinions with their spindle may all be made in one piece
of metal. The lower pinion, d³, engages a larger toothed wheel, d', which has
76 teeth and which is firmly secured to the upper end of the shaft, D. If the
bearings of the small pinions, d³ and do, are held immovable by locking the
sleeve, De, one revolution of the shaft, D', will produce fifteen-sixteenths of a
revolution in D. The bearings of these pinions are carried by the yoke and
sleeve, D. If, now, we hold D' from moving and turn the yoke, D', through one
complete revolution in the same direction which we previously turned D¹, the
shaft, D, will be turned through one-sixteenth of a revolution.
Thus, if racks J', J³, are meshed with spur wheels, D', D³, respectively, on the
same side and at the same time, and are made to turn these spur wheels to the same
extent (Figure 7), the pinion g on the shaft, D2, will be turned (18 +16) to precisely
the same extent. If these two racks, J, J³, meshed on the same side be con-
nected to the sliding frame, G' (Figure 6, Sheet 6), they will give to the pinion, g
(Figure 7), and rack, e, the greatest movement which my mechanism is capable
of imparting.
If they be meshed on opposite sides, thus turning their respective spur wheels in
opposite directions, they will give to the pinion g and rack e fourteen-sixteenths
(16) of the seven units of motion. If D' be turned seven units in one direction
and D one unit in the opposite direction the result will be expressed by fifteen-
sixteenths of one unit, minus one-sixteenth of seven units, leaving eight-sixteenths
of one unit.
Thus it will be seen that by connecting the spur wheel D' successively with the
vertical sliding frames G₁ to G' whilst D is locked immovable, we will obtain
successive movements of rack e equal to from 1 to 16 of one unit of motion.
If we connect the spur wheel D8 successively with the vertical sliding frames G¹
to G7, whilst D' is locked immovable, we will obtain successive movements of rack e
equal to from 1 to 10 of one unit of motion.
It will be readily seen, therefore, that by combining these motions either in the
same or in different directions any movement from 16 to 11 of one unit of motion
may be obtained in any direction.
Now, referring to Sheets 17 and 18, I will proceed to describe certain mechanism
which further connects my fabric moving mechanism with the embroidery machine.
Figure 35 is a plan view of the lower front portion of my device, partly seen in
Figure 4, Sheet 4. In Figure 35 we see a bent lever A¹ pivoted at a¹, and pro-
vided at each end with an open jaw. Near one end of this lever at a² is pivoted
a link A, which is partly shown dotted in Figure 1, Sheet 1. This link is
attached to a bell crank, one end of which engages a rotary cam on the main
shaft I, which imparts to the lever A¹ a regularly recurring oscillating movement
through the arc a (Figure 35). A³ is a curved lever pivoted at a, which stands
still unless it be coupled with A', as will be explained. Figure 38, Sheet 18, is a
section on line 38-38 of Figure 35-looking in the direction of the lower arrow.
We there see the lever A³ pivoted at a, carrying in its outer end a loose
vertically sliding coupling pin a, which has a dowel pin a' driven into it an
extending through a slot as of lever A³. This vertical coupling pin a is seen
to extend into the frame or housing, thus holding the lever A² from moving.
The dowel pin a' extends into a circular slot a' cut in a small block a0, which has
a downwardly projecting pin a", which slides in a suitable hole in the housing.
This block (see Figure 1, Sheet 1) has cast or fastened to it at an angle an
upwardly projecting arm a", which carries a small boss on its upper end through
which passes and is secured by a set screw the rod k before mentioned. This rod

page_text: 18 connected to the outside slide indicated in diagram 45, 80 as to be operated by
the Jacquard card.
Returning to Figure 38, Sheet 18, it will be remembered that the pin a' is capable
of oscillating back and forth in a circular slot a°. When the block a¹ is raised by
action of the card it carries with it the dowel pin a³ and coupling pin as, thereby
coupling the levers, A¹ and A' together at the same time loosing A³ from the
housings. Thus A³ will be made to move with A. In Figure 35 the lever A* is
shown to have an arm projecting forward beyond the pivot a³, to the end of which
arm is coupled by a swivel joint a horizontal rod A. The motion imparted
to A will, therefore; pull the rod A³ in direction of arrow, thereby regulating
shuttle mechanism on the embroidery machine, which may be united in suitable
manner to said rod. Thus the card controls the shuttle mechanism if such is
required.
ቢ
A curved lever A carries a similar combination of coupling and dowel pins
operated by a similar lifting block connected to the rod k", which is connected to
the other outside slide shown in the diagram, Figure 43. This lever A* has an arm
projecting forward beyond the pivot a which carries at its end a swivel A'. The
lower part of this swivel has a bore through which freely slides the rod A',
(Figure 39, Sheet 18). The swivel carries a latch A which engages a stop A
firmly secured to the rod A' by a set screw. When A is coupled to A' this lath
will be pulled in direction indicated by arrow (Figure 35), carrying with it the
rod A'. This rod connects with a proper shipping lever to arrest the motion of
the embroidery machine and of my mechanism.
From a pivot a's, extending toward the front is a double curved lever A10 which
carries a pin a near its front end. This pin, as shown in Figure 35, rests in a
notch in a curved slot in a shoe A". This shoe is rotatively mounted on a pivot A¹³.
The lever A10 is connected to the housings by a spring A" which tends to pull it
away from the embroidery machine. Should the shoe A" be pulled backward by
the wire a the pin A" will be released from its notch and the lever A" will fly
outward by action of spring A" (away from.embroidery machine) till it is stopped
by the pin A reaching the end of its slot in the shoe.
Figure 39 is a vertical section taken immediately in front of the latch A³. This
view shows the lever A10 in the same position as is shown in Figure 35. The
first action of the lever A10 in its flying outward will be to lift the latch A*
from its stop A, then by carrying this stop with it in its flight it will cause
the rod A' to stop the machine in the same manner as it would be stopped by the
lever A' as just explained. This mechanism is operated by the wire a" being pulled
backward, carrying with it the shoe A". This wire at its rear end is hooked
through a hole in a short lever a" which moves in a vertical plane about the axle a
(Figure 36). This axle is set horizontally in bearing a" which is carried by an
upright a¹ cast upon the housings. The lever a" is secured at right angles to a rear
bar a", which has two other levers a and a secured to it and extending downward.
It is also provided with a bracket a", which forms another inner bearing for this
trio of levers which are joined by the bar a¹.
The lever a has hooked into it a vertical wire a", and the lever a has hooked
into it, extending upward and backward at an angle, another wire a". It is readily
seen, Figure 36, that pulling either of these wires upward in the direction of its
length will operate to pull backward the wire a", thus stopping the machine.
The wire a extends upward some distance (Sheet 19, Figure 40), and passes
loosely through a hole near the end of a crank a", and has a small cotter run
through it above the crank, so that the crank may lift the wire a", but the wire
may pass freely up through the crank without disturbing it.
This crank a is secured to a shaft a2, which turns in bearings at some con-
venient place in the housings of the embroidery machine. This shaft has secured
to it a short upright crank a", which has drilled into it, near its upper end, a conical
recess a (Figure 41). In this conical recess rests one end of a rod a, the other
end of which is pointed. Near the middle this rod has a disk or enlargement a
c F.. :

page_text: This disk presses against a flange a", near the end of a hole a", drilled into a boss
on the housings of the embroidery machine, which hole has a diameter slightly
greater than that of the disk a 30.
This disk is pressed against the flange a" by the crank a whose tendency is in
a backward direction due to the weight of the crank a and the wire a”.
Near to the pointer a" and in a plane perpendicular to its length moves a board
upon which is drawn the pattern to be embroidered. This board is fastened to
the fabric frame before mentioned and moves with it. The pattern is surrounded
by a frame a whose thickness is greater than the distance of the pointer from
the pattern drawing. The area inside this frame represents the surface that.
may be covered by the extreme movements of the fabric frame in any direction.
A movement beyond these limits would cause damage and breakage. The device
shown on Sheet 19, Figures 40 and 41, is to prevent this accident, and operates
as follows: Should the fabric frame be moved beyond its prescribed limits, the
rear end of the pointer a will come in contact with the frame a³, thereby
deflecting this pointer about some point of the flange a as a fulcrum. This
deflection will cause the other end of the rod to be forced out of the vertex of its
conical resting place, and by pushing against the inner surface of this conical recess
it will press forward the crank a", thereby rocking the shaft a³, and lifting the
wire a, stopping the machine before any damage can be done.
The other wire, a, Figure 36, also operates to stop the machine in case of
accident, as will be explained hereafter.
When my mechanism is to be operated by hand it is necessary that some
means of preventing the starting of the embroidery machine by accident should
be provided. This provisional device is shown partly in Figure 35, Sheet 17.
To the housings a projecting boss A sustains a forwardly projecting pin A",
upon which is rotatively mounted a bell crank A", with an outwardly projecting
arm A, a downwardly projecting arm A" and a third arm A projecting upward,
all as in Figure 37. The lower arm A, Figure 37, is secured to the end of a long
horizontal rod A" by a swivel. The arm A is secured to a vertical rod A" also
by a snivel. If the arm A be pushed forward the bell crank will be turned
and the rod A will move in the direction indicated by arrow away from the
embroidery machine. This rod A" is connected to a clutch loosening the
driving pulley, or analogous interlocking device which prevents the machine from
being started.
The vertical rod A" extends up and is connected with the hand-operating device
(see Figure 8, Sheet 8). At or near the top of this rod is fastened a swivel A",
which in its turn is fastened to a lever A2, supported upon an upright bearing upon
the housings near its middle, and having its inner end resting underneath the
pinion D. This is the pinion (Figure 12, Sheet 10) which is fastened upon the
shaft or arbor which carries the handle D. Returning to Figure 8, Sheet 8, we
understand that when D is in gear with my mechanism the rod A will be lifted,
thus causing the rod A" to be pulled with the effect already stated of interlocking
the embroidery machine.
The
In describing the hand-operating device in the earlier part of this Specification
I spoke of turning the two shafts D' and D, Figure 7, Sheet 7. It was not
the place then to cloud the explanation by referring to the yoke-carrying
sleeves D, D, which revolve upon the lower parts of these two shafts.
reader can
now understand that when operating by hand it will be necessary
that these sleeves remain stationary whilst the spurs Ds and D" are released
from their racks.
Referring to Figure 13, Sheet 10, we see the meshing pins F and F in. two
vertical rows of four each. We will also notice that the first and third pairs F, F',
beginning from the top, are secured to two shorter brackets than are the second and
fourth pairs. These latter brackets Fº together with another similar one at the top
are secured firmly to shaft F. These extend forward beyond the meshing pins and
have holes bored near their forward ends. Through these holes passes loosely a

page_text: vertical sliding pin F. This pin is kept in place by a winged pawl F", secured to
the vertical rod A", which pawl fits into a slot Fin the pin F. The shape of
this winged pawl is best seen in Figure 9, Sheet 9. The engaging edge is in form
of an arc whose centre is the centre of the shaft F. The rocking of shaft F carries
with it the pin F10, whose notch F" rests and slides upon the upper surface of the
pawl Fu
The first and third pairs of meshing pins, F, F, counting from above, are secured
to the two shorter brackets FIs, which are joined rigidly together by a vertical
bar F. The lower bracket has cast to it a forward extension F1 in the form of
an arc whose centre is that of the shaft F. To the outer corner of this extension
is added an arm for moving by hand (see Figs. 14 and 14^). The pin F" passes
through this extension F1 and has its axis in line with the circumference of the
arc. The hole through which it passes is partly cut open, as seen in Figure 14ª.
Lower down and on the other side of the pin F is another notch F1 similar to F1.
When the rod A" is lifted, as stated, by the depression of the spur D18 of the
hand operating gears, the pawl F will raise the pin F10 till the notch F is in line
with the circular extension F. This will admit of an outward circular movement
of F about the shaft F by hand.
The mechanism of my attachment is so arranged that while the needles of the
embroidery machine are in the fabric the double racks are all released from their
respective spurs, and the spurs are, as stated before, locked by their pawls; and,
on the other hand, when the needles are withdrawn from the fabric the racks are
meshed and the pawls are withdrawn. It must be in this latter position when the
hand operating mechanism is to be used. The manipulation of this device is as
follows:
Referring to Figure 4, Sheet 4, the lever arm, A, should first be pushed over
toward the embroidery machine. This will operate the interlocking or arresting
rod A before mentioned, and also lift the rod A".
.
Now, referring to Figure 8, Sheet 8, it will be seen that this rod A", by means of
the pawl F, will lift the pin F and rock the lever A", thus leaving the spur D 18
free to drop into engagement.
The arm F (Figure 9, Sheet 9) is now pulled outward, thereby unmeshing the
top and third racks from their respective spurs Ds and D", whilst the other two
racks and spurs are in mesh, not so shown, however, in this figure. Thus the
sleeves D and D will be held stationary, whilst the shafts D³ and D' may be
turned by hand and the fabric frame moved as desired.
It, by an accident, more than one of the vertical sliding frames G' to G' should
be connected to the horizontal rack-frames, a destruction of various parts would
be the result. I have provided against such an accident in the following manner:
Figure 19, Sheet 12, is a vertical section on the line 19-19 of Figure 5, Sheet 5,
locking toward the rear; and Figure 23, Sheet 14, is a plan view of the same
portion of my mechanism. I have omitted the pins h and the guides for clearer
representation. There are seven slides in each group of eight, of which seven
only one must be left behind by the action of the card drum at the time: Above\
cach group of these seven slides, hanging vertically and straddling the group
between their lower ends, will be seen a pair of shears. The rear blades, P, of
these shears are rotatively hung from a rigid bar, P. The front blades, Pis,
which are pivoted to P" a little below the centre, are provided with forwardly pro-
jecting pins, P, which move freely in vertical depressions in a transverse bar, P18.
This bar is pivoted to the ends of two parallel cranks of equal length, P1, P1,
so that it always remains parallel to its normal position. These cranks
move through an arc of sufficient length to close the lower jaws of the shears just
far enough to admit the free passage of one of the slides i; see Figure 33, Sheet 16.
The hanging of the shears enables them to accommodate themselves to any position
between the limits determined by fixed stop pins P18. P1 is the active crank
and P the follower. The form of P is best seen in Figures 24, 25, Sheet 15.
Upon a hub p is cast an upwardly projecting flange pl which serves as the moving

page_text: crank for the bar P1, and a support for a cam p' which is circular and has its
centre in that of the hub. In the same plane as p' and at right angles thereto is
an arm p³. Projecting below the hub is a flange Q which forms the cam previously
mentioned in the description of rod O'. In Figure 20, Sheet 13, this casting is
seen mounted upon an axle Q' upon which it rotates freely and is held on by a
cotter. The arin p³ rests upon a longitudinal bar p¹. This is shown in detail
Sheet 15, Figures 28, 29. The bar p, the hub p³, and the two bosses p, p, are all
parallel and rigidly joined together by a web as shown, the whole forming a
crank Q. The shaft Q', Figure 20, Sheet 13, rests in a bearing Q, and is firmly
secured at its forward end in the hub p', of the crank Q. To the forward end of
the bar p is pivoted on a crank pin a link Q (see Figure 1, Sheet 1), which is
connected to one end of a bell crank Q%, the other eud of which plays in a rotary
cain on the main shaft I, which gives to the link Q a reciprocating movement in
direction of its length. This rocks the crank Q3 with its shaft Q
Underneath the cam p² (Figure 19, Sheet 12) of the crank P17 is seen a pawl p³.
This pawl is secured to a shaft p", which passes through the longer boss p upon
the crank Q (see Figure 23), and carries secured to its forward end a lever p
notched at its outer end as seen in Figures 26 and 27 on Sheet 15. Fitting into
these notches is a corresponding projection at the end of another lever p", which
latter is secured to a small shaft which is rotatively mounted and held by a cotter
in the shorter boss p' of the crank Q. A spring p¹ between this lever and a hook
on the longer boss 16 (Figure 23) presses the notches in the ends of these levers
together, thus requiring a considerable force to separate them. This (Figure 19,
Sheet 12) keeps the pawl p8 in position underneath the cam p². This pawl på and
the horizontal bar p move in a rocking motion with the crank Q', and carry with
them and between them the crank P", which gives a reciprocating movement to
the bar P, thus closing and opening the jaws of the shears. This movement is
just sufficient to close the jaws far enough to admit the passage of a single slide i.
The shears straddle the slides i near their rear ends (see Figure 5), and any slide i
which is moved forward escapes from between the shears. Should two or more
slides remain behind by accident, such as a rent in the Jacquard card, the jaws of
the shears will not come near enough together, the bar P16 cannot complete its full
motion, a sudden resistance will be offered by the cam p² to its pawl sufficient to
push the pawl from its normal position, thus rocking the shaft p and shearing the
two levers p and p" apart. The lever p° carries near its end a forwardly
projecting pin po, which engages a slot near the end of an upright crank p
This crank (Figure 20, Sheet 13) is cast to a hub pand is continued below the
hub and then bent backward horizontally till it reaches just beyond the sliding
pin P, previously mentioned. A downwardly projecting toe p' (Figure 19,
Sheet 12) from the end of p" engages permanently a slot in the pin P. The
resistance opposing the closing of the shears, disengaging the pawl p³, throws
downward the lever, carrying with it the crank p. This movement throws the
pin P into the hole P in the bell crank P³, thus coupling the semicircular crank P
with Ps, and loosing it from the housings (see Figure 20). This crank, P7, will
therefore move with P. The pin P8 in the end of P' will pull downward the end
of the flat bar 01, thus releasing this bar from the cam Q. By this time the
turning of shaft P upon which the semicircular crank P7 is secured, has brought
the rod P against the slides i which have remained behind and will push them all
forward. At the same time (see Figure 23, Sheet 14) the rocking of shaft P
turns a crank p" secured to its inner end, pulls upward in direction of its length
the wire a, thus stopping the machine (Sheet 17, Figures 35 and 36).
It might happen that one of the pins, h, after passing freely through the card,
will meet some obstruction in the drum, and be pushed with its slide i forward a
part of the way. Referring to Figure 5, the bar O descending would probably
carry such slide back again by pressing into its proper notch. But, should the
slide offer resistance, and remain stationary, while partly advanced, the rod O
cannot complete its descent (see Figure 20, Sheet 13;) the crank O³ with its

page_text: 1
horizontal bar O will offer resistance to the cm Q and prevent it from turning.
This cam is formed integrally with the crank P (see Figure 19, Sheet 12). Any
interruption to its movement will therefore interrupt those of the crank P. Thus
the saine result will transpire; the shaft P will be rocked, the slides pushed
forward out of danger, and the machine stopped. Such stoppage will call attention
to the existence of a defect and give opportunity for proper repair.

the machine, and with it my mechanism, an endless cord R (see Figures 2 and 3)
passes around four, more or less, sheaves S (only two of which are shown) near
the corners of the embroidery machine, said cord being secured at some convenient
portion of its length to the lever or other device for shifting the driving belt to or
from the driving pulley on the main shaft. This cord R, passing completely
around the embroidery machine, enables the operator to start or stop the machine
wherever he may be standing.
Before specifying my claims of invention, I desire to have it understood that
the principles underlying the mechanism of my fabric-moving device can be
employed with many modifications. I have been particular in describing the
construction of the parts of my device in considerable detail, stating how certain
parts are connected to others by means of set-screws, or by being cast together,
and otherwise. It is evident that, nevertheless, by other forms of connection the
same results could be accomplished. Again, I have described the particular
machine which is represented in the drawing as operating with the aid of slides
and Jacquard pins by which four double racks are controlled in seven units of
motion; or, in other words, each rack is capable of a step by step movement under
the influence of the jacquard, there being seven such steps for each rack. But
instead of having this number 7, it may he 8, 9, 10, 6, or any other desired number.
So, with regard to the differential gear, I have described the relative difference as
represented by 15, while clearly the same principle may be brought into play if
any other difference be selected. And in other respects my mechanism can be
modified by the skilled mechanic, without departing from the spirit of my invention:
I therefore desire it to be particularly understood that I do not limit myself to
the precise details or numbers of parts and forms of constructions shown in the
drawing or described in the Specification. I have simply endeavoured to clearly
state one form in which my invention may be clothed. Other forms will readily
occur to those who may choose to enjoy the fruits of my invention.

:
In addition, I wish to say that whenever I use the term "Jacquard card" or
"Jacquard mechanism or "Jacquard drum or Jacquard pins" in this
Specification, I mean to embrace by said terin any pattern mechanism of analogous
kind adapted to perform analogous service. A perforated Jacquard card may be
sed, as shown, or one having no perforations whatsoever, but, instead, projections
might be used, or no card at all might be used. A cylinder having projections
properly applied according to the pattern desired to be produced or, in fact, any
analogous pattern regulating mechanism, is by me understood to be the equivalent
of the Jacquard mechanism specified. In this sense I desire the term "Jacquard
to be read in this Specification. I need not state also that in lieu of levers and
cams indicated in this Specification and drawings in connection with the essential
parts that are to be moved, other mechanical contrivances may be used with like or
substantially like effect.
"
I will further have it understood that throughout the Specification where I use
the words "on one line" I mean a single line of direction in the plane of the
Jabric, which line may be horizontal, vertical, or inclined.
While I consider the above described mechanism as being but one of the many
forms in which my invention may be clothed, it can, nevertheless, be construed broadly
as generic mechanism, and is capable of analysis into.the following elements :-To
begin with, we have a fabric frame; then there is mechanism directly connected

page_text: to said fabric frame for actuating the same, that is to say the guides, the racks d, e,
and the vertical shafts; then there are one or more moving mechanisms, that is to
ay moving racks or their equivalents for imparting varying ranges of movement
to the fabric frame actuating mechanism; then there is a compounding mechanism
for compounding the motion imparted to the fabric frame actuating mechanism by
the moving mechanisms. This last is shown as differential gearing, but it will be
understood that any suitable compounding mechanism may be used, the character
of which will vary with the varying conditions of practice. Such differential
gearing I have here shown as a part of the actuating mechanism of the fabric
frame, and as interposed between the moving mechanisms and the guides which
directly move the fabric frame.
It will be observed that the pinion teeth f, g, co-operate with the rack teeth d, e,
to move the frame but once the frame is in motion and it is desired to stop it, the
pinions f, g, are stopped and the rack teeth engaged therewith at the instant are
stopped from motion and consequently stop the frame. Thus the pinion teeth form
stoppers for co-operating with the contacting surfaces of the rack teeth to stop the
motion of the frame.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
