2 Claims. (Cl. 45---138)
This invention relates to a mattress tufting
ie machine, for example, to the right side, as
machine and particularly to a machine which is viewed in Fig. 1. Approximately at their cen
intended to hold and compress the mattress, par
ters the links i3 at each end of the machine are
ticularly at the points at which tufts are to be connected together by the pivot i5. The other

A further object of the invention is to provide
an improved tufting machine in which the mat
tress can be readily compressed and moved in
compressed condition into horizontal and vertical
positions to facilitate the tufting operation.
A further object of the invention is to provide
an improved actuating means for compressing a

mattress.

A further object of the invention is to provide
an improved frame construction for a mattress
tufting machine.
Other objects, advantages and capabilities of
the invention will appear from the following de
scription of a preferred embodiment thereof,
taken in conjunction with the accompanying
drawings, in which:

At each end the frame I Si carries a bracket

Fig. 2. The brackets I9 carry outwardly pro

able bearings 2l mounted on the upper end of
standards 22. These trunnions are preferably
located approximately at the center of the com
pressed mattress so that the frames when loaded
and the mattress compressed, are substantially

ing frame which includes a longitudinal channel
member 23 and transverse feet or supports 24.
The feet 24 are rigidly connected to the chan

The standards are suitably held rigid by means
of straps 25 connected thereto and‘to projecting
portions of the channel member 23. It will read

merals I!! and II designate two frames which
are of a size to enable them to receive between
them a mattress to be tufted.
These frames are
relatively movable into their extreme positions
'50 shown in Figs. 3 and 4.
The frame I0 carries
upstanding rods I2 which are received in open
ings in the upper frame II so that the frames
are maintained in register. A link I3 is pivot
ally connected to each frame Ill and I I by piv

the supporting frame provides an open space in
On its under side the frame Iii supports a ro
tatable shaft 26. At one end, that is, the left
hand end as viewed in Figs. 1 and 2, the shaft 2S
has rigidly secured thereto an actuating handle
21 of substantial length. The portion of the
handle 2l adjacent the? shaft 26 is in the form
of a hook so that this shaft may clear the brack
40
et I9 in moving between the positions shown in
Figs. 3 and 4, and vice versa.
It will be under
stood that the actuating handle 2l' operates be
tween the standard 22 and
adjacent ends of
the frames ID and ll. A link 228` is pivotally con as 01
nected to the shaft 21 and to the upper frame
I‘I. 'I‘his link is bent, as shown in Figs. 3 and
4, so as to clear the bracket I9. rl‘he link 28
is located on the inner side of the operating han
dle 2l and on the outer sides of the links I3 so
that the handle 27 may be swung without it or
the link 28 fouling other parts of the mecha
nism. The outer end of the actuating lever 21,
that is, the part remote from the shaft 26, is oíf

set as shown in Fig. 1, to enable it to be grasped
by hand and moved past the frames Il) and I l.
At the other end of the machine the shaft
positions inwardly directed arcuate compressing
26 rigidly carries a hooked arm 29 which is ar
members 45 are bellied inwardly so as to com
ranged in alignment with the hooked end of the
lever 21. The arm 29 is of the same shape as
the hooked end of the lever 21 for the same rea
son, that is, to enable it to clear the bracket i9
at the adjacent end of the machine. The arm
29 is connected to the center of the top vframe
ll by a link 30 which is similar to the link 28
and located in alignment therewith. The lower
frame i0 is secured in the horizontal or vertical
position by means which will hereinafter be de
scribed. The pivotal connections between the
link 28 and lever 21 and between the link 30 and
the arm 29 are arranged to pass the plane of
the centers of the upper pivots of the links 28
and 30' and the center of the shaft 26. Conse
20 quently, when a mattress is inserted between the
frames l0 and H, these frames being in the re
lation shown in Fig. 3, and the lever 21 is thrown
in the counter-clockwise direction into the po
sition shown in Fig. 4, the upper frame ll is
25 drawn downwardly and the lower pivotal con
nections of the links 28 and 36 move past the
central vertical plane so that the frames are
automatically locked in mattress-compressing
relation. After the tufting operation has been
30 completed and the frames have been brought
members 45 are mounted between adjacent strips
42. As best shown in Fig. '7, the compression
press the mattress more strongly at their posi
tions. The compression members 45 are provided
with central openings 46 to enable the workman
to tuft through the most highly compressed por
tions of the mattress. The grid structures 4l be
ing removable, they may be replaced by other grid 10
structures, giving a different desired tuft spacing.
The grid structure 4l may be assembled from the
strips 42 and 43 and the arcuate compression
members 45 by welding.
The operation is as follows: The frames are
latched in their horizontal position by the latch
34 by merely moving them into that position.
The lever 21 is swung into the position shown in
Fig. 3 so as to distend the frames l0 and Il. A
mattress to be tufted is then placed between the 20
frames so as to rest on the lower frame I0. The
lever 21 is then swung in the clockwise direction,
as viewed in Fig. 3, into the relation shown in
Fig. 4. The mattress is thereby compressed and
the portions of the mattress at which tufts are 25
to be applied are more strongly compressed by
the compression members 45.
As previously
noted, the compression linkage is automatically
locked in compression position. The latch 34 is
then unlatched and the frames are swung in the 30
into- the horizintal position sho-wn in Fig. 4, the
clockwise direction, as viewed in Fig. 4, until they
lever 21 is swung in the clockwise direction and
on the completion of the movement of the lever
21 the lower pivots of the links 28 and 38 are
35 located on the right-hand side of the central
vertical plane so that the frames are automati
cally lo'cked or held in the distended relation
shown in Fig. 3. The finished mattress can now
are latched in vertical position, as shown in Fig.
5. The workmen now perform the tufting op
readily be removed.
The lower frame I0 is provided on one side
with a rail 3|, the major length of which is
spaced outwardly from the frame towards the
adjacent standard 22. The standard has formed
thereon a bracket 32 which carries an inwardly
_ projecting plate 33 which is adapted to engage
the rail 3l when the frame is in its horizontal
position. A latch 34 is pivotally mounted on the
bracket 32 and is biased by a spring 35 into
the position shown in Fig. 6. When the frames
I0 and Il are swung from their vertical posi
.50 tion shown in Fig. 5 into their horizontal posi
tion shown in Fig. 4 (in the clockwise direction
as viewed in Fig. 5 and in the counter-clock
wise direction as viewed in Fig. 4), the rail 3l
slips past the latch 34 into engagement with the
55 plate 33. The latch then closes into the position
shown in Fig. 6 and the frames are held hori
zontal until the latch 34 is released. When the
latch 34 is released by moving its lower end in
wardly, the frames l0 and Il may be swung in
60 the clockwise direction, as viewed in Fig` 4.
When the frames are swung intoI a vertical posi
tion the end of the rail 3| enters a recess 36 of
the latch member 31 and the frames are locked
in the vertical position.
The latch 31 is pivot
eration passing their needles through the aligned
openings 46 of the two frames. When the mat
tress has been completely tufted, the latch 31 is
released and the frames are swung into horizon
tal position, in which position they are held by
the latch 34. The lever 21 is then swung in the
clockwise direction, as viewed in Fig. 4, and the 40
frames are distended so that the completed mat
tress may be removed. It will be noted that the
compression linkage including the lever 21, arm
29, shaft 26 and links 28 and 3|] being exclusively
mounted on the frames, swing with the frames 45
Vwithout relative movement thereto and maintain
vthe frames in their position of adjustment until
the lever 21 is actuated.
Although the invention has been disclosed in
connection with the specific details of a preferred 50
embodiment thereof, it must be understood that
such details are not intended to be limitative of
the invention except in so far as set forth in the
accompanying claims'.
