3 Claims. (Cl. 271-34)

The commercial operation of this machine is position and the container, designated by I6, is

Figure 2b is a cross section of the belt.

Figure 3 is a plan view of a machine embodying
our invention.
In Figures 4 and 5 is a detail of our cam and
lever connections.

In Figure 3 is shown a conveyor consisting of
m' a series of belts, I, whose outside surface has
been specially treated, with emery, for the pur
pose of picking a fabric piece from the pile in the
special container which is directly underneath
and to the rear of the belts. The fabric pieces
30
picked off of the pile designated by 2, cling to
the series of belts l and are conveyed to the roller
belts designated by 3, where it is, in turn, con
veyed to the presser roller 4.
The forward and backward movement of the
35 container, designated by 5, is caused by the oper
ation of levers designated by 6 and ‘I.
The le
vers are pinned to a rod designated by 8‘ and are
controlled from the arm, designated by 9 which
is pinned to the rod 8.
40
Figures 4 and 5 are a portion of the side of our
machine containing the operation of our side arm
lever, designated by l0. Connected to the same
rod as lever I0 is the arm designated by I I, which
is the connection between the rod and the box
45 cam 12. The function of the lever is performed
by moving back, causing the spring end, desig
nated by E3, to release itself from the teeth on
the container rack, designated by Hi, through
pressure against the block designated by [5.‘ A
3:1 0 short rise in the box cam I2 causes the levers
to release the container allowing it to come for
ward so the fabric pieces in said container press
against the picker-off belts and when the roller
passes the rise, the levers force the container
55 back in order to give the piece of fabric, just
are grooved so that the wheels of the container
may set ?rmly. These tracks are also adjust
able for the greater or lesser degree of gravity
feed for the container. The tracks are attached
to the frame at the points designated by l8‘ and
I9‘. The track at point I8 is pinnedbut at point
IS the joint may be loosened so that the track
may be raised or lowered in the slotted portion
of the frame designated by 20. The tracks are 20
made adjustable due to the varying weights of
the different types of fabrics. A stack of heavy
fabric pieces would require less pitch than a stack
of light fabric pieces.
Figure 1 is a side view of our machine attached
to a standard ironer. The stacked fabric pieces,
designated by 2|, are placed in the container
designated by 22. The upper portion of the fab
ric pieces rests against the back rest, designated
by 23, and the tops of these pieces are in the 30
direct alignment with the picker-off roller and
belts designated by 24. In the forward move
ment of the containen'the stack of fabric pieces
presses against the picker-off belts and is con
veyed to its destination.
The upper edge of the
fabric piece cannot fallback when being carried
around the roller as it has been picked up at a ‘
point which is approximately the extreme upper
edge of the fabric. We have placed a metal plate
under the conveyor belts designated by 25, for the
purpose of eliminating the falling of the edges of 40
the fabric piece.
The end of this plate, as is shown in Figure 3,
has ?ngers, designated by 26, projecting between
the carrier belts. The ?ngers guide the piece of 45
fabric material to the drum of the ironer.
Figure 2, reference character I, is a detail of
our coated belt. The V belt has been specially
coated with emery. This emery may be attached
to the belt by glue, shellac, blastings, etc. 21 50
designates the coating on the outside face of the
belt.
