2 Claims. (Cl. 101-26)
This invention relates to a machine for spot
treating, especially spot-marking, multiple fabric
layers and more particularly superposed fabric
layers that are to be cut into parts of garments
5 orrthat represent already-cut parts of garments.
In cutting the parts of garments in a garment
factory, it is the practice to withdraw the cloth
from a bolt and to build up a pile or large multi
plicity of cloth layers. The cutter then chalks
10 the outline of the garment parts from suitable
patterns on the top layer of the pile; and prior
to cutting out the various parts or blanks from
the pile by the usual automatic cutting machines
or after the parts have been cut, it is customary
15 to locate certain spots in a pile of parts, for in
stance, the spots where buttons are to be sewed,
buttonholes made, and pockets or other parts
attached. This has sometimes been done by pull
ing a marker thread through a pile of the parts;
20 and, prior to separating the parts from the pile,
the spot at which the thread passes is marked
with chalk for subsequent location by the oper
ator to Work on the parts. Accordingly, another
operator is usually detailed to chalk-mark each
2 Ul blank or part at the appropriate spot, namely, the
spot coincident with that through which the
thread had passed when the blank was in a pile.
This latter operation of chalk-marking is time
consuming and monotonous, since each part must
30 be handled and marked separately.
In accordance with the present invention, the
spot-marking of each of a multiplicity of super
posed fabric layers is effected without disturb
ing -or handling each of the layers through the
35 use of a marking instrument in the form of a
hollow needle whose hollow has an outlet at or
near the needle point. The method hereof in
volves passing such needle through the superposed
fabric layers so that the outlet from the needle
40 hollow'is surrounded by the fabric of each of
the layers in succession; and, while the needle
is passing through the superposed layers, caus
ing a marking fluid to flow progressively through
the needle hollow as a ñne stream impinging
45 against such layers successively as it is being
emitted through the outlet and thus marking the
fabric surrounding the spot in each layer through
which the needle passes. While the method here
of might be performed with machines of various
50 designs, it is preferable in any event to provide
a machine wherein the needle necessary for the
performance of the method hereof forms part
of an advancing and retracting needle holder
whose advancing and retracting strokes are both
55 accompanied by the passage of the needle through
the superposed fabric layers and at least one of
Whose strokes is attended by the emission -of the
fine stream of marking fluid through the needle
hollow outlet against the fabric of each layer
surrounding the spot through which the needle
passes. When the needle-holder is advanced by
a suitable handle, it is possible to construct the
machine hereof so that the marking fluid is emit
ted from the needle hollow during both the ad
vancing and retracting strokes of the needle
through the multiplicity of superposed fabric lay
ers. Thus, the machine hereof may have a res
ervoir for the marking fluid or equivalent source
of supply leading by way of a normally closed
valve to the needle hollow, communication be 15
tween the reservoir and the needle hollow being
established preferably by automatic opening of
the valve by suitable means as the needle in its '
advancing stroke penetrates into the pile of fab
ric and being disestablished preferably by auto
matic closing of the valve as the needle in its
retracting stroke emerges from the pile of fabric,
although the >opening and closing of such valve
may in some instances be under manual control
of the operator.
25
With the foregoing and other features and ob
jects in view, the present invention will now be
described in further detail with reference to the
accompanying drawing, wherein,
Figure 1 is a side elevation, partly in section, 30
of a machine for performing the method hereof.
Figure 2 is a plan view of such machine.
Figure 3 is a sectional detail on the line 3--3
of Figure 2, looking in the direction of the arrows.
As shown in Figure l, the machine hereof may 35
comprise a base or work support I0 upstanding
from which is a pedestal or frame II inclusive
»of a forwardly projecting arm or bracket I2 con
siderably above the base I0 and a fabric-gauge
I3 fixed so as to be vertically adjustable, as by 40
bolts I4, to a slide I5 at the front edge of the
pedestal Il. The arm I2 terminates at its front
end portion'as an elongated vertical bushing or
tubular guide I6 for a vertically movable cylin
drical rod I1 whose lower end portion serves as 45
a holder for the hollow needle or punch I8 and
Whose upper end portion is suitably secured to
a handle I9, as will presently appear.
The needle I8 shown is hollow from its upper
end to its lower or pointed end I8a, which may 50
advantageously be left solid so as to minimize
needle breakage as the needle point penetrates
into and through a thick pile of fabric, as well as
to prevent fabric lint from clogging the needle
outlet and to avoid displacement or deviation of 55
2
2,118,718
the needle point away from a substantially per
pendicular line as it encounters the flexing stress
incident to its being driven through the pile.
Immediately above the needle point I8a, the nee
dle may have one or more outlets I8b for its hol
low interior, which outlets preferably occur
through opposite side walls so that marking fluid
may be emitted therefrom to opposite points of
the fabric immediately surrounding the needle
as it is passing through the fabric.
The upper
end portion of the needle may be suitably fixed
within a tubular holder 20 whose upper end por
tion is threaded into a socket afforded by an en
largement or knob 2I at the lower end portion
15 of the rod I1.
Leading from the interior 20a of the needle
holder 20 is a flexible‘hose 22 which communi
cates by way of a valved pipe 23 to a reservoir
24 for holding the marking fluid. The valve 25
20 in the pipe 23 is normally closed, but it is adapted
to be actuated by a lever 26 to which is pivotally
secured a crank 21 constituting the vertically
movable core piece of a solenoid 2B whose elec
tric circuit is closed in the course of the down
25 ward movement of the handle I9 to open the
valve 25 and is opened in the course of the up
ward movement of the handle I9 to close such
valve, as will presently be described.
The portion of the rod I1 above the bushing I6
30 may terminate as a block or head 30 from whose
side walls project pins 3I slidable within slots 32
formed in the opposite walls 33 of an enlarged
open intermediate handle portion. The lower or
left end portion of the handle may terminate as
35 a hub 34 secured for pivotal movement on a pin
35 in between a pair of bearings 36 at the upper
end of the pedestal II. 'I'he retractive or up
ward stroke of the handle I9 may be caused auto
matically, as by a compression spring 31 encom
40 passing the rod I1 in between its head 30 and the
upper end of the bushing I6.`
The electric circuit for the solenoid 28 com
prises a wire 49 leading from one terminal of the
solenoid to a contact-piece carrier 4I fixed to
45 the handle I9 immediately below or beyond the
intermediate handle portion. Such contact piece
4I may carry a Contact pin or button 42 pro
jecting yieldingly from the front face of such
piece and passing into an opening in such piece
50 `with its inner end 4-3 flanged over an annular
shoulder añorded at the inner end of a sec
ondary enlarged opening 44 containing a com
pression spring'45 for bearing yieldingly against
the inner end of the pin 42. The outer or back
`end of the opening 44 may be closed by a suitable
insulator plate 46 secured in between the back
of the contact-piece carrier and the handle I9,
as by a pair of bolts 41. The other terminal of
the solenoid leads by a wire 49 to a suitable source
60 of electricity, which source also supplies electric
current by a wire 49 to a contact piece or mem
ber 5I] upstanding from the upper face of the
arm or bracket I2 and insulated therefrom as by
an electro-insulator plate 5I.
65
The upper end of the contact piece 50 is im
mediately below the contact pin 42; and, when the
handle I9 is depressed, the pin 42 is brought into
yielding engagement with the back face of the
piece 5'0 on arcuate path or line 53, indicated in
70 dot and dash in Figure 1, to close the circuit of
the solenoid and thus to open the valve 25. 'I’he
limit of downward travel of the handle is de
fined by a stop element 54V at the lower end of
the path 53, against which sheet the pin 42
75 strikes to arrest the downward movement of the
handle. When the handle is released and the
spring 31 acts to elevate it automatically to its
normal position shown in Figure 1, contact be
tween the pin 42 and the piece 50 is broken and
the electric circuit of the solenoid 28 is thus
opened with attendant closing of the valve 25.
The operation of the machine hereof may be
briefly described as follows.l The pile of fabric
or fabric parts P may be placed on> the base II)
and the gauge I3 adjusted vertically to exert the
desired clamping or holding pressure on the top
of the pile and thus to prevent dislodgment of
the superposed fabric layers. The outer end I3a
of the gauge I3 is shown as being an apertured
guide through whose aperture the needle I8 passes 15
on its way through the fabric pile, as such a guide
acts to prevent undue flexing or bending of the
needle such as might otherwise tend to take place
when the fabric pile is especially thick or re
sistant to piercing and/or when the needle tends 20
to flex under heavy load in the absence of a
guide. It is thus seen that the needle guide I3a
serves to keep the needle properly located
throughout the fabric pile as well as to inhibit
undue flexing of the needle such as might other 25
wise cause needle breakage. Once the fabric pile
is accurately placed in the machine with the spot
to be marked immediately under the needle guide
I3a, the handle I9 is depressed until it is stopped
by reason of the pin 42 striking against the stop 30
element 54, at which time, as depicted in dotted
outline in Figure 2, the needle has penetrated
throughout the fabric pile, whereupon the han
dle is released and is automatically elevated or re
stored by the spring 31 to its normal position
shown in Figure 2.
In the advance or downward stroke of the han
dle I9, the contact pin 42 makes contact with the
contact piece 50' just as or slightly after the
needle I9 penetrates into the fabric pile P, in 40
consequence of which the valve 25 is opened and
kept open while the needle passes downwardly
through the pile to the very lowermost fabric
layer, as seen in dotted outline in Figure 2, and
while the needle is passing upwardly through 45
the fabric pile in its return stroke. This means
that marking fluid is emitted through the needle
outlets IBb as the needle passes substantially all
the way down and all the way up through the
fabric pile. The base I0 of the needle is shown 50
as provided with an opening 9 into which the
point of the needle may enter at the end of its
downward stroke, which opening may extend to
an absorbent pad or felt 8 capable of absorbing
such drippings as the needle may yield at the end 55
of its downward stroke. As already indicated,
the emission of marking fluid may begin to take
place slightly after the needle has entered the
fabric pile, that is, after the uppermost outlet I9
has passed, say, the uppermost three 0r four 60
fabric layers. Because the needle carries some
marking fluid even after the supply of marking
fluid thereto has been stopped, the few uppermost
fabric layers that may have remained unmarked
during the descent of the needle therethrough 65
are generally marked during the ascent of the
needle therethrough, In order to prevent the
discharge of any significant amount of marking
liquid through the needle outlets I9 after the
needle has emerged from the fabric pile, a suit 70
able valve 1 may be provided at the point where
the hose 22 delivers the marking liquid into the
needle holder 20, which valve 1 may be designed ,
to check flow of such residual liquid as may be
containedv in the hose 22 by reason of such valve

requiring greater pressure or head of liquid for
its opening than that afforded by the residual
liquid in the hose 22.
It is, of course, desirable to change the point
at which the needle begins and stops emitting
marking liquid, since the depth or thickness of
the fabric pile being spot-marked may vary from
time to time. Such change may be had by mask
dust or like dry pigment as the marking medium
presents the advantage that it may be readily
brushed or dusted off the finished garment.

removab-ly and adjustably secured to the piece
50, as by fasteners 5 slidable within an arcuate
bonding medium locally into the body of each of
slot 52 in the piece 50. It is obvious that a num
ber of such shields 6 may be available to corre
spond to different depths or thicknesses of pile
of fabric to be marked. So as to enable the oper
ator to know at once the particular shield to be
used with a particular thickness of fabric pile,
the slide l5 may carry graduations or marks
denoting the particular shield that is serviceable
with a particular setting of the gauge I3 thereon.
It is also possible to provide a single shield that
is readily adjustable on the contact piece 50 to
mask more or less of the inner face of the con
tact piece 50 in terms of graduations associated
with the arcuate slot 52 and in terms of the set
ting of the gauge I3 read off from the graduated
scale associated with the slide I5.
Various fluid marking media may be used pur
30 suant to the invention hereof, depending upon
the color and other characteristics of the fabric
to be marked. For instance, when blue serge
is the cloth being marked, a suspension of very
finely ground white pigment in Water or other
volatile medium may be kept in the reservoir
for the marking medium.
In other instances,
wax as such or dyed or pigmented Wax in molten
condition or dissolved in organic solvents may
serve as the marking medium, especially when
the finished garments made up from the marked
fabric parts are to be ironed under heat and such
wax or such dyed or pigmented wax spots as are
Visible in the ñnished garments can be oblit
erated through volatilization of the particular
45 pigment and/or dye and/or wax employed. In
still other instances, the marking medium may
consist of a solution, suspension, or dispersion of
dye, pigment, or other coloring agent in water
or other volatilizable liquid medium, the par
ticular dye, pigment, or other coloring agent se
50
lected being capable of being volatilized or de
colorized under ironing heat. When the mark
ing medium is a dispersion or emulsion of suit
able marking material of either liquid or solid
55 character, such dispersion or emulsion may be
stabilized by suitable protective colloids or emul
dental spots, thereby effecting spot-welding or
spot-bonding of all the layers. Similiarly, a
multiplicity of superposed fabric layers may be
locally dyed, or infused with gas, perfume, or
other agent which one might wish to incorporate
only locally into each of the bodies of a` super
posed plurality of fabric layers, that is, while
preserving the main body of each of the fabric
layers against the effect of the agent thereon
and/or such weakening action thereon as might
ensue through widespread or dense punching or
piercing thereof.
