1 Claim.
This invention relates to tufting buttons and
more particularly to a button especially designed
for use in tufting mattresses.
The object of the invention is to provide a
5 tufting button of simple and inexpensive con
struction capable of being quickly and con
veniently attached to the opposite ends of a loop
(Cl. 24-102)
The improved tufting button forming the sub
ject-matter of the present invention may be used
on mattresses, cushions, pillows and upholstery of
all kinds, and by way of illustration is shown ap
plied to a conventional type of mattress, in which
5 indicates the top of the mattress and 6 the ?ll
ing thereof. The tufting button is preferably
of cord or other binding material for the pur
pose of holding the loop under tension after hav
10 ing been threaded or otherwise passed through
the body of the mattress.
A further object of the invention is to pro
vide a tufting button having a transversely split
stamped, pressed or otherwise formed from a
single metallic blank of the construction shown
in Figure 6 of the drawing, said blank being pro- 10
vided with terminal enlarged portions '3 and 8
united by a relatively narrow integral connect
ing web 9. The metal at the outer edges of the
head to permit ready application of a cord loop
thereto, said head being provided with a depend
ing eye adapted to receive and frictionally en
as indicated at H], in simulation of a clover leaf 15
while the inner edges of the said enlarged por
gage said cord loop.
A further object is to provide a tufting button,
tions are preferably straight and disposed at sub
the head of which is concavo-convex in cross sec
of the connecting‘web 9, as indicated at H. In
fabricating the button, the metal constituting the 20
connecting web Q is bent or pressed laterally to
form an attaching eye l2 and this bending or
tion to impart additional strength and rigidity
thereto while the upper surface of said head is
devoid of projections so as to present a smooth
unobstructed surface to the bed covering.
A further object is to provide a tufting button
which is stamped or otherwise formed from a
1.3 O
enlarged portions 7 and 8 is preferably scalloped,
stantially right angles to the longitudinal plane
pressing operation brings the terminal enlarged
portions '5 and 8 of the blank in juxtaposition
to each other, as illustrated in Figure 4 of‘ the
single metallic blank having terminal enlarged
drawing, thereby to produce ‘a button comprising
portions united by a relatively narrow connect
ing web whereby, when the blank is pressed into
two lobes normally separated from each other
by an intervening transverse slot M with the
attaching eye integral with the head of the but
permanent shape, the enlarged portions thereof
will be disposed in spaced juxtaposition to each
other to form the head of the button with the
connecting web looped at one side of said head
to form the attaching eye of said button.
A still further object of the invention is gen
H orally to improve this class of devices so as to
increase their utility, durability and e?iciency.
In the accompanying drawing forming a part of
this speci?cation and in which similar numerals
of reference indicate corresponding parts in all
40 the ?gures of the drawing:
Figure 1 is a perspective view of a portion of
a mattress provided with my improved tufting
button,
Figure 2 is an enlarged vertical sectional view
45 taken on the line 2-2 of Figure 1.
Figure 3 is an enlarged top plan view of one
of the tufting buttons detached,
Figure 4 is a transverse sectional view taken
on the line 4-—4 of Figure 3,

Figure 5 is a similar view taken on the line 5-5
of Figure 3,

the button is formed, and

ton and bridging said slot. The lobes I3 con- 30
stituting the head of the button are preferably
concave-convex in cross section to impart addi
tional strength and rigidity thereto and the upper
surface of the head of the button, it will be noted,
is entirely devoid of surface projections so as to 71,7,
present a smooth unobstructed surface to the
bed covering. The walls of the attaching eye l2
converge in the direction of the lower surface of
the head of the button so as to form a constricted
throat l5 communicating with the slot l4 and 40
through which the twine or cord loop I1 is in
troduced when applying the button thereto. It
will thus be seen that the button comprises a
transversely split head having an attaching eye
integral therewith and so connected with the 45
mating lobes constituting the head of the button
that the cord loop may be quickly and con
veniently attached to the button or removed
therefrom at will. It will also be noted that,
when the tufting buttons are attached to the 50
opposite ends of the cord loop l1, said buttons
will bear against the upper and lower faces of
the mattress and maintain the loop under ten
sion at all times.
The buttons are, of course, arranged in pairs 55

and in applying said buttons to a mattress one
end of the cord loop I‘! is passed through the slot
M in the adjacent button and a longitudinal pull
exerted thereon until it contacts with the closed
end of the attaching eye, after which the cord
loop is threaded or otherwise passed through the
?lling 6 of the mattress and the other end of the
tendency to close the transverse slot Ill and thus
assist in preventing accidental displacement of
said cord loop.
It will, furthermore, be noted that the closed
' cord loop inserted Within the slot in the head of
end or saddle of the attaching eye I2 is con
cavo-convex in cross section, as indicated at l9,
so as to present a transversely curved smooth
upper surface for contact with the cord or twine
the mating button and in which position both
and thus prevent cha?ng or cutting of the twine.
10 buttons will be securely anchored on the mattress
and the cord loop maintained under tension at all
times, as will be readily understood.
As previously stated, it is preferred to scallop
the outer edges of the lobes constituting the head
15 of the button in simulation of a four-leaf clover
so as to give the button a neat attractive ap
pearance, but it will, of course, be understood
that the heads of the buttons may have any de
sired marginal outline so long as the head of the
20 button is transversely split and provided with an
integral depending attaching eye.
In Figure 7 of the drawing, there is illustrated
a modi?ed form of the invention in which the
mating lobes constituting the head l8 of the but
25 ton are substantially semi-circular inv shape so
that, when the blank is pressed into permanent
form with the lobes of the head in juxtaposition,
said head will be substantially circular in outline.
Inasmuch as the attaching eye I2 is integral
30 with the lobes constituting the head l3 of the
button and said lobes are normally separated, it
follows that the head of the button is more or less
resiliently supported on the eye with the result
that, when the cord loop I‘! is introduced within
the eye, the tension on the cord loop- will have a
It will, of course, be understood that the tuft 10
ing buttons may be made in different sizes and
shapes and nickeled, Japanned or otherwise coat
ed to give them a neat attractive appearance
without departing from the spirit of the inven
tion.
Having thus described the invention, what is
claimed as new is:
A tufting button comprising a head consisting
of companion sections having parallel confront
ing inner side edges extending across the head
in close proximity to each other, and a substan
tially U-shaped shank consisting of a narrow
strip integrally united at its ends to opposed
medial portions of the inner side edges of the '
head sections in appreciable spaced relation to
ends of the inner side edges and. having its arms
converging upwardly and at their upper ends dis
posed in close proximity to each other to form
the shank into a substantially closed eye, the 30
head sections being of concavo-rconvexed forma
tion to provide a dished head having a concaved
under face with the shank located centrally
thereof.
