The operation of the invention is as follows: The di

into account the area to be covered, the width of the
material, the number of pleats desired, and the distance
to be covered by the returns. With the dimensions thus
established, the device It} is adjusted to make the ?rst

While I have shown and described in considerable
detail what i believe to be the preferred form of my
invention, it will be understood by those skilled in the
art that various changes may be made in the shape and
arrangement of the several parts Without departing from
the broad scope of the invention, as de?ned in the follow

I claim:
1. A device for making returns, spaces and pleats in
draperies, comprising a base having a frame projecting
therefrom, said device having means de?ning a narrow
slot through which drapery material can be passed and
the frame 12 to place the lateral projection 43 of member
over the graduation on scale
corresponding to
the dimension for the return. The thumbscrew 69 is
then tightened to lock the slide lit in adjusted position.
1‘. e thumbscrew 52 is then loosened, and the shank 5d
of the pleating book 51 is moved up or down through
the block 47 to place the hook 51 directly above the
graduation on scale 53 corresponding to the pleat depth
dimension.
The edge of the drapery material is then hooked onto
the pin 57 of the holder 56, while the latter is positioned
as shown in FIGURE 1. The material is carried up
over the member 42 and is passed under and around the
hook 51, and back down over the member 42. Hold
ing the material down ?rmly against the underneath thick

determined pleat depth dimension, and means for lock

the material or inserts a pin therein, measuring from
the pin of the ?rst pleat. The first return and ?rst pleat
are then placed on the base plate it behind the frame _

and up over the frame 12. Holding the material taut,
with the ?rst pleat drawn snugly against the back side
of the shoe 21, the operator moves the slide 20 up or
down to place the pin groove 46 directly under the mark
be has previously made on the material. He then tightens
the thumbscrew 6G, to lock the slide 20 in adjusted posi
tion.
Leaving the ?rst pleat in place behind the shoe 21,
the operator carries the material up under and over the
hook 51, then down over the member 42, where he in

said slot whereby each succeeding pleat is spaced apart
from the preceding pleat by said predetermined space
dimension when said preceding pleat is engaged and
held by said slot as the new pleat is formed and pinned.
2. A device for making returns, spaces and pleats in
draperies, as de?ned in claim 1, wherein said drapery

on said base for swinging movement between an operative
position and an inoperative position, said pin holder
