Improvements in the Mode of and Apparatus for Pleating or
Crimping Paper or Fabric.
PAUL TRACY 18 Compton Street Goswell Road London Engineer, JAMES EDWARDS
CATTY and JAMES DOBSON Stationers of 8 Dyers Buildings Holborn London, do
hereby declare the nature of this invention to be as follows:-
This Invention consists of a development of an ordinary chain pleating machine
whereby the pleats are turned up or down at an angle on either or both sides.
In carrying the invention into effect we cause the paper or fabric that is to be
pleated up or down respectively to project beyond the chain on either side, and during
its passage between the chains it is forced into shape against the sides of the chains
(which are shaped to receive them) by means of suitable mechanism (fingers worked
by springs).

COMPLETE SPECIFICATION.
Improvements in the Mode of and Apparatus for Pleating or
Crimping Paper or Fabric.
PAUL TRACY, 18 Compton Street, Clerkenwell E.C. JAMES EDWARDS CATTY,
JAMES DOBSON both of 8 Dyers Buildings Holborn EC do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention consists in the construction of a pleating or crimping machine for
pleating or crimping paper or other suitable material, and is carried out in the
following manner.
I provide or construct a pleater of the shape shown in side elevation in fig 1. of
the accompanying drawings, and in plan in fig. 2. Fig 3 shows end elevation of
pleater a, showing angular end e; d spring for controlling the action of the movable
piece c, which is pivotted at ¹ to the lever b, which is in turn pivotted to the pleater a
at b. Fig 4 shows in side elevation two endless chains of pleaters a and a¹ connected
together by means of links g' pivotted together at g, the pivots are prolonged a
sufficient distance to allow them to engage in the spur wheels f, f. In the accom-
panying drawing a sufficient number of pleaters are drawn to indicate my invention,
the dotted lines in fig. 4. represent their continuation. ff are two similar spur
wheels for actuating the top chain of pleaters a The spur wheels are actuated by any
well known means such as cogwheels or endless chain. Their bearings may also be
suitably formed in any convenient manner. h is an inclined plane suitably supported
at h¹.
Referring again to fig. 1, it will be seen that if the lever b is raised in a vertical
direction the piece c will also be raised in a vertical direction. The arrows indicate
in the several figs. (4, 5, & 6) the direction of motion of the various parts.
Referring to Fig. 4 When the chains of pleaters are moved in the direction of
the arrows by means of the spur wheels, the pleaters a' in coming together and gearing
with the pleaters a, in the top chain, will form at their ends at the point marked a³ an
angle which may be acute or obtuse as desired according to the shape of the ends of
the pleaters. Along this angle the pieces c, are caused to glide by the action of the
inclined plane h, on the ends of the levers b, thus causing them to descend as shown.

page_text: When the levers have arrived at the end of the inclined plane h, they will return to
their initial position on the pleater owing to the action of the spring d, aforesaid and
shown in fig. 1. The other ends of the pleaters a' carry similar pieces c, and levers b
with springs d; the said pieces being operated by a similar inclined plane in an upward
direction, on the angle formed by the meeting of the ends of the top pleaters a.
The paper or other material to be pleated or crimped enters in the form of a strip
between the pleaters at the point y, and the strip of material being slightly wider than
the length of the pleaters, the sides of the strip of material are turned (or pleated)
up by the movable pieces c on the lower pleaters, while the other side of the paper
is turned down by the movable pieces on the upper chain of pleaters.
When the pleated material passes out from between the pleaters at 2, it enters a
device shown in fig. 5, for compressing and closing the folds or creases given to the
same by the pleaters 1, is a toothed or other wise driven wheel, which by means of
the spindle 10, actuates the toothed wheels 2, 2, and the spur wheel 51, through the
medium of the bevel or mitre wheels 3, 3, the spur wheel 51 being driven directly
from the spindle 4. The spur wheel 11 is driven directly from the spindle 10 and the
spur wheel 11' is driven by means of the bevel or nitre wheels 12, 12'; the spur
wheels 5, 51, 11 & 11', all move at the same velocity in the direction of the arrows
and by engaging with the folds or pleats of the paper or other material 8 as it leaves
the pleaters, the paper or other material is forced along the shoot or guide as shown
by the lines 93, in Fig 5 Fig. 6, shows side elevation of the shoot or guide with
the spur wheels removed. This shoot or guide may be suitably supported to any
framework as shown at 17, 171, the top strip 9' is hinged at 91, and retained in position
by means of a screw bolt 14 and nut 18 and controlled by the spring 13. 16 is a
catch piece or spring secured by the nut 15 and allows the paper when sufficiently
compressed to escape and fall into a suitable receptacle.
The pleaters a & a' may be secured to the links 9¹ by any suitable means, such as
rivets or screws. The ends of the spindles 4, 10, 7, and 6 are supported in a suitable
framework.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
(1) The combination and arrangement of machines for pleating & crimping paper,
or other material, substantially as described and for the purpose set forth.
(2) In pleating or crimping machines, the pleaters a, in combination with the
movable piece c, lever b, and spring d´substantially as described and for the purpose
set forth.
