United States Patent No. 2,055,433, Sept. 22,
In the accompanying drawings, Fig. l is a front
1936, granted to H. J. Goosman and the present elevation of an electric sewing machine cabinet
' applicant, discloses a cabinet of this nature in
which a motor-controller is adapted to be se
re. cured to the inside of one end wall of the cabinet,
in which position it may be actuated by a knee—
treadle mounted within the cabinet and adapted
to be swung to a concealed position when not
in use. The construction disclosed in that patent
15; also permits the motor-controller to be detached
from the cabinet and placed on the floor to be
actuated by the foot, to suit the preference of
individual operators.
Inasmuch as the electric current to operate the
20 machine is normally introduced into the cabinet
at, the upper portion thereof it will be readily
understood that a materially greater length of
conductor cord will be required to connect the
motor-controller with the motor and the source
25 of supply when the motor-controller is placed on
the ?oor than when it‘ is located within the
cabinet for knee operation.
To maintain this extra length of cord concealed
when the machine is not in use it has heretofore
30. been the practice to provide such devices as spring
vclips behind which the folded up surplus cord
may be held, or spaced arms around which the
surplus cord may be wound. Thus the devices
heretofore provided have required manual ma
ggnipulation of the surplus cord in order to con
ceal it from view.
This invention has an object to provide an
electric sewing machine cabinet embodying a
motor-controller adapted selectively to be placed
40in the cabinet for knee actuation. or on the floor
for foot actuation, and a cord controlling device
adapted automatically to take up the slack in
the cord and hold it in a concealed position when
the motor-controller is placed in the cabinet.
A further object of the invention is to provide
for this purpose, a cord controlling device which
is simple in construction, e?icient in operation,
relatively inexpensive to manufacture and which
will not interfere with the placing of the motor
5() controller on the floor or shift it when it is in
that position.
With the above and other objects in view, as
will hereinafter appear, the invention comprises
the devices, combinations and arrangements of
55 parts hereinafter set forth and illustrated in the
embodying the present invention, showing the
sewing machine in its operative position and the
motor-controller in a position to be actuated by 10
the foot of the operator, the cover leaves of the
table being shown as extended and broken off.
Fig. 2 is a fragmentary view similar to Fig. 1
but showing the motor-controller positioned
within the cabinet, for knee actuation, and with
the cord controller holding the surplus cord in a
position in which it is concealed when viewed
from the normal angle of vision of an observer.
Fig. 3 is a transverse vertical section through
the cabinet, substantially on the line 3—3 of Fig. 20.
2, with the cover leaves closed and the sewing
machine head illustrated in dot-dash lines in the
position it occupies when lowered within the
cabinet.
Fig. 4 is an enlarged side elevation of the sup
porting means for the cord take-up arm, later
to be described, and the spring means for actu
ating said arm‘.
Fig. 5 is a plan view of Fig. 4 showing the take
up arm secured to the back wall of the cabinet.
Fig. 6 is a detail sectional View taken substan
tially on the line 6-6 of Fig. 4.
Referring more speci?cally to the drawings, the
invention is disclosed as embodied in a sewing
machine supporting and enclosing cabinet com
prising a body portion designated generally as A
and consisting of a front wall I, a rear wall 2,
left and right end Walls 3 and 4, respectively,
and supporting legs 5 adapted to rest upon a
floor indicated by the line i. A sewing machine
head H is hinged tothe cabinet and is adapted
to be raise-d into the operative position shown
in full lines in Figs. 1 and 2 or to be lowered into
the cabinet as indicated in dot-dash lines in
Fig. 3. The machine head includes an electric 45
driving motor M, and current to actuate the mo
tor is introduced through a supply cord S con
nected with a terminal block 6 secured to the
sewing machine frame. The motor M is con
nected with the terminal block 6 in the usual
manner. A motor-controller C also is connected
with the terminal block and thence with the mo
tor by a conductor cord 1 which is held, inter
mediate its ends, between the two members of a

of the arm H.
As shown by Fig. 1, the motor-controller C is
adapted to be placed on the floor for actuation
by the foot of the operator. Also, as shown by
Figs. 2 and 3 the motor-controller may be placed
within the machine cabinet and actuated by a
Although the cord 1 and the arm II are visible
in the straight side view shown in Fig. 2 it will
be understood that in practice when in that po
sition they will be concealed from view in the
normal angle of vision of an observer. This is
true because of the fact that the take-up arm
and the cord are located on the back wall of
the cabinet, which latter is approximately
eighteen inches wide, and when the cabinet is
resting on the floor the normalv angle of vision
knee-lever 45 fulcrumed at 33 on a bracket 30
secured to the front wall I of the cabinet. When
10 not in use, the knee-lever may be swung upwardly
about a pivot 44, to a concealed position, as
shown in Fig. 3. Any suitable means may be pro
vided for removably supporting the motor-con
troller in the cabinet and any suitable means may
15 be employed for actuating the controller from
the knee-lever.
One suitable form of support for the motor
controller and one operative connection between
the knee-lever and the controller are disclosed
20 in detail in United States patent to Daniel H.
Chason, No. 2,065,428, dated Dec. 22, 1936. These
elements have been indicated in dotted lines in
Figs. 1 and 2 of this application and comprise a
sheet metal support Hi secured to the inside of
25 the end wall 4 of the cabinet and provided with
a spring tongue 2'! which engages and yieldingly
retains the motor-controller, as clearly set forth
in the above mentioned Chason patent. The
connection between the knee-lever and the mo
30 tor-controller includes a thrust member 40 adapt
ed to be actuated by the knee-lever and to en
gage and shift the pedal slide I5 of the motor
controller, also as shown and described in said
35
Chason patent.
It will be apparent that when the motor-con
troller is lifted from the ?oor and placed in the
cabinet, for knee-actuation, there will be an ex
cess of conductor cord 1, which, unless controlled,
would dangle below the body portion of the‘cabi
net and be unsightly.
This invention provides means for automati
cally controlling the surplus conductor cord and
for placing and holding it in a concealed posi
tion when not required. This device comprises
a cord take-up arm II, preferably of wire, piv
oted at one end upon a screw-stud l2 secured
to a plate l3 which overlies the insulation block
8. The plate [3 is secured to the rear wall 2
of the cabinet by the screw 9, which also secures
the insulation block thereto. The plate I3 is
provided with tangs l3a which engage the cab
normally obscured by the front wall of the cabi
15
net. Furthermore when the cabinet is closed and
the machine head is lowered therein the verti
cally movable apron l8 is‘forced downwardly to
the position shown in Fig. 3 and also serves to
conceal the cord and the take-up arm.

From the foregoing it will be apparent that
this invention provides a sewing machine cabi
net having novel means for automatically con
trolling and concealing the conductor cord with
out in any way interfering with the normal and 25
selective operation of the two-position motor
controller.

Having thus set forth the nature of the inven
tion what I claim herein is:
1. The combination with a sewing machine cab 30
inet, of an electric motor driven sewing machine
mounted thereon; a controller-support within
said cabinet; a motor-controller adapted to be
placed on a floor beneath the cabinet for foot ac
tuation or to be placed within the cabinet and 35
secured to said controller-support; a conductor
cord connecting said motor-controller with the
electric motorv of the sewing machine; and means
including an arm pivotally mounted within the
cabinet adjacent said controller-support and pro
jecting therefrom and having at its free end an
operative connection with said conductor cord
and spring means tending to lift said arm for
automatically taking up the slack in said con
ductor cord when the motor-controller is placed 4.5
within the cabinet, said spring means being of
such strength as to have its lifting force over
come by the weight of said motor-controller when
the latter is placed on the floor.

the screw 9. The free outer end of the arm II is
formed as an eyelet or ring pl Ia which forms a
adapted selectively to be placed on a floor he
neath the cabinet for foot actuation or to be'
placed within the cabinet for knee actuation; 'a 55 '
conductor cord connecting said motor-controller
with the electric motor of the sewing machine;
and means including a pivotally mounted spring
guide through which freely passes the cord 1.
A bow spring l4, having one end secured between
a clamp nut l6, threaded on the screw l2, and
the plate 13, has its free end I lie slidingly em

of an observer is downwardly toward the cabi
net and therefore the cord and take-up arm are
a motor-controller
bracing the arm H and normally urges the arm
actuated cord take-up arm having a portion em- '
upwardly toward the position shown in Fig. 2.
It will be understood that the spring I4 is
bracing said cord substantially midway between 60
sufficiently strong to raise the arm H and the
cord ‘I to their uppermost or concealed position,
when the motor-controller C is lifted but that
it is sufficiently weak so that it will not shift the
65
motor-controller when it is located on the floor.
A stop l1, secured to the rear wall 2 of the
said motor and said controller for automatically‘
forming a loop in said cord and moving it. to a
substantially concealed position when the motor
controller is lifted from the floor to be placed
within the cabinet; and stop means to limit the 65
movement of said take-up arm.
