Improvements in Button-holė Barring Machines!
I, HENRY PAUL FEISTER, Manufacturer of 1733 Montgomery Avenul,” Phila-
delphia, in the County of Philadelphia, State of Pennsylvania, United States of
America, do hereby solemnly declare the nature of my invention for "IMPROVE-
MENTS IN BUTTON-HOLE BARRING MACHINES," and in what manner the same is to
be performed to be particularly described and ascertained in and by the following

My invention consists of a machine for finishing button-holes, embodying means
for holding securely, and guiding and automatically clamping and releasing the
material containing the worked button-hole. in such a manner that the needle and
thread of the sewing machine will stitch a substantial bar across the unfinished end
of the button-hole. This bar, as made on my machine, is formed of a series of
transverse stitches, laid, one on top of the other, at right angles to the length
of the button-hole, which series of long transverse stitches is afterwards overseamed
by a number of short stitches, crossing the transverse stitches side by side, and very
close together. As the long stitches are laid at right angles to both the length of
the button-hole and the bed-plate of the machine I call them long transverse
stitches; and as the short stitches are laid in the same direction as both the length
of the button-hole and bed-plate of the machine, I call them short longitudinal
stitches. The formation of this combination of stitches is accomplished by having
the cloth or other material to be operated upon, shifted under the needle point,
between each descent of the needle, in its stitch-forming operations. This shifting
of the goods I accomplish by having a carrier, A, go through the necessary
operations, and by clamping the goods fast to said carrier by means of an automatic
clamp B. This carrier, A, is a flat piece of metal pivoted at one end by the
stud, A² (Fig. 4) to the sliding block, P, which slides lengthwise in the slot, P,
cut out in the table or bed-plate, I, of the machine. By this arrangement the
carrier, A, is susceptible of being oscillated transversely on its pivot, A², or of
being vibrated longitudinally on the bed-plate I, by reason of its connection with
said slide-block, P. Hence I term my carrier a vibrating and oscillating carrier.
These separate movements may be made independently or both together; and in
forming my bar, I first cause the carrier to oscillate transversely, to form the long
transverse stitches which constitute the bed or foundation of the bar: I then cause
the carrier to vibrate longitudinally, thus forming the short longitudinal stitches,
which overseam the long transverse ones just made, and at the same time 1 cause

page_text: my carrier to slowly move transversely, so that the short overseaming stitches will
not be at one place, but evenly distributed along the long under stitches, side by
side and close together.
At the opposite end of the carrier, A, from the pivot, A², is the throat, A¹ (Fig. 2)
or opening, through which the needle passes in sewing. In order to properly
locate the material, in the first instance, and to more firmly secure it during the
after operation of sewing the bar, I place on the carrier an adjustable guide. This
adjustable guide is a metal projection somewhat similar in shape to a button-hole,
consisting of a blade, C, (Figs. 1, 2 and 4) and a post, C', over which the button-
hole is slipped. This post, C, is mounted on a flat piece of metal, C², provided
with a slot, C³, for adjusting, through which slot passes a screw, C', entering the
carrier, A, and thus securing the post to the carrier at any desired distance from
the blade, C. The goods clamp, B, is pivoted at B to the standard, B³, on the
carrier, A, and is further extended by the spring arm, B4, which is connected by a
joint, adapted to allow the free play of the guide when operating both ways, with
the carrier, A, to the elbow-lever, D, (carrying a roller, D', which rests upon the
disc, K.) so that when the latter is depressed by the spring, D', the clamping end
of the clamp, B, over the carrier, A, will be elevated, thus automatically releasing
the goods.
The mechanism for imparting to the cloth carrier the necessary movements is
actuated directly from the intermittently driven shuttle-shaft, M, of the sewing
machine. I do this by pinning to the shuttle-shaft, M, of the machine, a suitable
cam or gearing, which actuates a pawl and ratchet wheel, in connection with the
shaft H, which shaft I will denote the carrier actuating shaft. In the first modifi-
cation of this device, as shown in Figure 3, 1 have a cam, E, pinned to the shuttle-
shaft, M, and provided with a properly curved slot, E¹, entered by and guiding the
roller, E, carried at one end of one of the arms of the elbow-lever, E³. This
elbow lever, E³, is pivoted to the bed, I, by the stud, E, and carries on the end of
its other arm the pawl, F, held in operative position by the spring, F. The
pawl, F, engages with the ratchets on the periphery of the ratchet wheel, G,
mounted on the carrier actuating shaft, H, which shaft is journalled in the bed-
plate or table, I, and carries the mechanism for directly operating the carrier. In
this modification, the movements of the shuttle-shaft, M, (which movement is an
element of the original sewing machine) causes the cam, E, to turn, by which
turning the curved slot, E', forces the elbow lever, E³, to swing on the pivot, E,
and thus carry the pawl, F, secured to the elbow lever, E³, backward and forward
over the periphery of the ratchet wheel, G, whereby a ratchet is engaged, and said
wheel, and the shaft, H, on which it is mounted, is rotated step by step. This
modification may be employed on machines which have either a vibrating or
revolving shuttle shaft, the cam, in either case, being timed to cause the lever E³
to vibrate as described. The device is so timed that at every vibration or
revolution of the shuttle shaft, M, the pawl, F, drops back one ratchet, and
engages therewith, and returns, carrying the ratchet wheel, G, and the shaft, H,
one step around. By this means, the shaft H, carrying the mechanism for shifting
the carrier, A, is given an intermittent rotary motion. The same timing is used in
both of my other modifications, about to be described, and with similar effect to
the shaft, H. The device is also so timed that the ratchet wheel, G, and shaft, H,
can never operate while the needle is down in the material. Hence the carrier, A,
which is solely dependent upon the shaft, H, for its motive power, can never shift
while the needle is in the goods. In my second modification of the device for
actuating the shaft, H, I pin to the shuttle-shaft, M, a gear wheel, J, (Figs. 6 and 7)
working in the rack, J, suitably hung from the bed-plate, I, to allow a sliding
movement in the direction of the double-headed arrow, J³, from side to side. This
rack is provided with a pawl, F, which engages with the ratchet wheel, G,
as in the former modification, with exactly the same result. In my third
modification of the device for actuating the shaft, H, from the shuttle-shaft,
M, I pin to the shuttle-shaft, M, a bevel gear-wheel, O, which operates in a

page_text: curved-rack, O¹, occupying a segment of the ratchet wheel, O³, (which is mounted
loosely on the shaft, H) carrying the internal ratchets, r, r,r (Figs. 8 and 9), which
engage with the pawl, F. This pawl, F, is mounted on a disc, H', which is fast to
the shaft, H, hence each step by step movement of the disc carrying the engaging
pawl, F, is imparted to the shaft, H.
In each of these two last described modifications, the vibratory movements of the
shuttle-shaft, M, turn the gear wheel, J, in Figs. 6 and 7; and O, in Figs. 8 and 9,
back and forth, which in turn imparts a forward and backward movement to a
vibrating rack (.J', in Figs. 6 and 7; and O' in Figs. 8 and 9) with which, in each
case, the gear wheel is engaged. In each case also the ratchet and pawl movement
is operated by the rack, with a result similar, i.e., the imparting of an intermittent
rotary motion to the shaft, H.
Having shown my device for imparting to the shaft, H, an intermittent rotary
motion from the shuttle shaft, M, I shall now describe how the proper movements
are given to the carrier, A, by the intermittent rotation of the shaft. H.
On the shaft, H (Figs. 1, 2 and 4) I fasten, above the bed-plate or table. I, a
disc, K, carrying on its under face, two or more (according to the number of long
transverse stitches intended to be made) small rollers, h, h, projecting downward.
Each roller, as the disc, K, rotates, is brought around so as to bear against one end
of the elbow lever. L, which is pivoted to the bed-plate, I, by the stud, L'. This
elbow lever, L, is provided with an arc-shaped slot, L³, on its other arm, which
slot is entered by a thumb-screw, L³, passing through the link, N, which is pivoted
to the carrier, A, by the stud, A. The object of this slot, L3, and swinging ſink, N,
is to provide a means for adjusting the length of the oscillations of the carrier, and
consequently, regulating the length of the bar, as well as to connect the elbow
lever with the carrier, A. As the disc, K, revolves, the rollers, h, h, in turn bear
against and force the lever, L, outward, thus moving the carrier, A, as shown in
the dotted lines of Fig. 2. sidewise on its pivot, A. After the passage of the
roller, the elbow lever, L, is forced back to its former position by the spring, L,
by which means the carrier, A, is also moved sidewise, in the opposite direction to
its last move, and back to its former position. The next roller then coming into
operation and acting as the first one, again causes the carrier A to move sidewise
once more, and so on; which to and fro movement of the carrier A constitutes the
oscillation necessary to make the long transverse stitches. It is by this means that
the goods clamped to the carrier A are shifted, between each downward stroke of
the needle, from side to side, and the long transverse stitches forming the bed or
foundation of the bar are laid at right angles to the length of the button-hole.
A similar device (Figure 3) placed under the table or bed-plate, I, of the
machine, is used to impart to the carrier the short longitudinal movement whereby
the short overseaming, stitches are made. To a disc, or preferably, to a ratchet
wheel, G, when the first or second modifications of my actuating device, before
described, is used, or to the disc, H' (Figs. 8 and 9) when my third modification is
used, I fasten, on the upper face, a number of small upright rollers, y, g, g, etc.,
(according to the number of overseaming stitches intended to be laid) similar to
the rollers, h,. These rollers, g,, g, as the shaft H rotates, one by one bear on
the face of the block R, which is fastened securely to the sliding block, P, to which,
as already described, the carrier A is pivoted. Therefore the block R is sus
ceptible of being vibrated longitudinally, and every movement of the block, R, is
communicated to the carrier A. As the ratchet wheel, G, in the first and second
modifications, or the disc, H', in the third modification, revolves, the rollers g, 9, 9,
come into play, and one by one force back the block R, which between the passage
of each roller is returned to its normal position in the path of said rollers by the
action of the spring R¹ which is pinned to the bed-plate of the machine. In this
manner the transverse vibratory movement is imparted to the carrier A, and hence
to the goods clamped thereon. I have so arranged these separate sets of rollers,
that but one set shall operate at one time, the upper set giving the long transverse

page_text: stitches first, the lower set afterwards operating the carrier to form the overseaming
stitches on top of the transverse ones.
Now it will be observed that in the formation of the short overseaming stitches,
they would all be in the same place, that is, one on top of the other, the same as the
long stitches, unless some means were used to move the carrier slowly sidewise while
its short longitudinal movements are being effected. This I accomplish by means
of a cam K (shown by the dotted lines on Figure 2 and in section on Figure 4).
This cam I place on the lower side-projecting downward of the disc K, and it is
so shaped that its effect on the elbow lever L will be to slowly force it back while
the lower set of rollers, 9, 9, 9, is giving the short longitudinal vibratory motion
to the carrier A. This forcing back of the lever, L, of course has the effect of
drawing the carrier in the desired sidewise direction while vibrating lengthwise, and
the overseaming stitches being formed by the needle are properly and evenly
distributed along the long transverse stitches.
I will now describe my device for automatically stopping the machine at the
completion of each bar. On the main driving shaft, W (Fig. 4) of the machine, is
hung loosely a belt-and fly-wheel V, having a number of projections or lugs, S', S¹,
so placed as to couple with a corresponding number of similar projections or
lugs S2, S3, carried by a clutch-and-brake disc, T, which I fasten to the main
shaft W, so as to revolve with it, but also, so as to slide loosely lengthwise_along
it for a limited distance, to allow the two sets of lugs, S¹, S, and S*, S³,
to be coupled and uncoupled. The brake disc, T, has also cut around it an
encircling slot, T', into which projects the upper end of the upright arm of the
elbow-lever D, which lever is pivoted to a standard and bearings on the bed-
plate I at D³. I fasten to the upright part of the arm of the machine, I', a friction
disc, S, surrounding, but entirely disconnected from the main shaft W. This disc
is stationary and is faced with leather, S, and is mounted at such a distance from
the disc T that it will interfere with, and be firmly pressed by, the disc T at the
very instant that the disc T is carried away from the belt-and-fly-wheel V, and the
machine unclutched.
On the upper surface of the disc K is constructed a ledge projecting upward at
right angles to the plane of the disc K. On this ledge the roller D, at the end of
the horizontal arm of the elbow lever D is kept firmly pressed by the spring D'.
At a certain point, calculated to act at the proper time to stop the machine at the
completion of the bar, on the projecting ledge K³, I have an opening K', downward
into which the roller D is forced by the spring D' the instant that the same is
presented by the intermittent rotation of the shaft H. This downward movement
of the lever D causes its upright arm to slide the clutch and brake-disc away from
the belt and fly-wheel V. and toward the friction disc S, a sufficient distance to
uncouple the two sets of projecting lugs, S₁, S', and S2, S3, and to bring the brake
disc into contact with he leather face S' of the friction disc S. By this device not
only is the motive power completely cut off from the machine, but any possible
momentum of the main shaft and dependent mechanism is immediately arrested by
the forcible contact of the brake and friction discs. As before explained, the cloth
is at the same time released from the pressure of the clamp, leaving it free to be
taken out without effort on the part of the operator.
The machine is started by pressing the treadle X (Fig. 1) which draws down the
rod X' (Fig. 4) lowering one end of the lever X, fulcrumed at X', to a standard
projecting downward from the upper side of the bed or table I. This depression
of one end of lever X³ elevates the opposite end, which being connected by the
rigid rod X' to the horizontal arm of the elbow lever D, elevates said elbow lever,
drawing the roller D' out of the slot K', and coupling the lugs S, S₁, and S³, S³,
whereby the machine is at once started to run until the slot K is once more
presented to the roller D' by the intermittent rotation of the shaft H, which will
not be until another bar has been worked complete.
The cloth is, at the same instant that the machine is started, automatically

page_text: clamped into position, fast to the carrier A, by reason of the automatic spring
arm B*, connecting with the lever D, as before described.
