Year: 1897

page_text: This Print is in accordance with the Original Specification as it stands after
Amendment (under Section 11 of the Patents, &c. Act, 1883), as required by
the decision of the Comptroller General, of the 8th day of July 1898.
Date of Application, 26th Apr., 1897
Complete Specification Left, 18th Jan., 1898-Accepted, 26th Mar., 1898
WILLIAM HENRY CHRISP, 18, Tindal Street, North Brixton, London, S.W.,
do hereby declare the nature of this invention to be as follows:-
The machine has two blades, steel. One long side of each blade has three
edges. Each blade strikes the other on top alternately. Each blade forces the
material into the heated copper and brass sinking which contains great heat.
The heat is caused by the plates being surrounded by atmospheric air and gas
jets, by Tee shaped gas barrel.
The pressure of gas is regulated according to material.
The whole of the machinery is adjustable so as it can make from of an inch
pleat, to 2 inch pleat altering bolts, nuts, plates and slots.
The machine is made of wrought iron, copper brass and steel.
On the outside of these two plates, are two long spindles.
Each pair of set screws, are four inches apart.
The two extreme set screws force the blade out, and the two inner screws raise
the blades.
One long plate is on a socket.
As the pleating is sinking down, the brass, copper and iron plates give with the
pressure.
The machine is worked by a cog-wheel fixed on each spindle, and on the end of
one of the spindles a heavy fly wheel is fixed to carry the machinery round, and on
the centre of this fly wheel a cog-wheel and chain is attached, so as it can be
driven by the feet similar to a sewing machine.
The plates are five feet six inches long, by 12 inches wide by 1/8 inch thick.
The blades are five feet four inches long, three inches wide by 1/8 inch thick
and are adjustable.
The blades are fixed between two strips of iron, five feet four inches long
1/8 inch thick and two inches wide. Second length of iron five feet four inches
long 1/8 thick and one inch wide adjustable by bolts and nuts.
Each of these complete blades has three heavy spindles, to press the pleating into
the sinking.
At the end of the machine are two iron plates, 18 inches high, 12 inches wide,
by 1/4 inch thick.
In each of these plates are three slots, six inches long and 3/8 of an inch wide,
and two holes for revolving spindles, and four iron legs bolted on.

page_text: An Improved Pleating Machine.
I, WILLIAM HENRY CHRISP, of 18, Tindal Street, North Brixton, London, S.W.,
Clerk, 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 relates to an improved pleating machine.
My invention will be more particularly understood by reference to the annexed
drawings in which at
Figure 1 a mid section transversely of a machine in which blades are fitted"
for the alternate overlapping, said view also showing the means or appliances by
which the degree of overlap or pleat is maintained or adjusted.
Figure 2, side elevation of machine, and
Figure 3, plan.
A, A, represent the two blades.
These blades are affixed and adjustable as to extent of projection and also as to
angle, if tapered pleating is required, between two plates 1, B, which are supported
at their ends on the frame C of the machine and on which they have combined
reciprocating and lifting and falling motion, the lift being effected by the tips C¹
of the screw bolts D riding in contact with the horizontal plates E, the back or
outward motion by the tips F of the screw bolts G riding against the vertical
plates H and the inward or return motion by the springs I, I, one being at each
end and affixed to eyes J, J, of the tables K, K, which are secured to and move
with the plates E and H.
The screw bolts D and G are arranged at nearly right angles to each other on
their respective shafts K K' which receive rotation by the gear L L when the
crank handle M is rotated the shafts K' K' running the full length of the machine
and working in bearings in the end frames C, C one of them having a fly wheel N
for steadying the motion. The travel of the screw bolts D) on each side alternately
draws back the blades from the fabric and the bolts G lift the blades, and as
the tips of the bolts G clear the plates H, the springs I draw the blades inwardly
to make a fresh pleat.
The tables K, K with the plates B and blades A are adjustable as to the extent
of inward travel by the screw bolts P, P, which are passed through lugs Q, Q,
projecting from the ends of the tables K, K.
Directly under the centre of the machine is a receptacle R down which the
fabric as pleated by the two blades A, A, alternately in an opposite manner
descends and presses upon a platform S termed a sinker, the pressure being due
to the resistance of the weights or counterpoise T which keep the pleats flat, in
conjunction with the upward pressure against the blades A, A, while the feed
is taking place.
The receptacle R is in two parts and these hang from the plates U, U, which
are adjustable by the slots and bolts V, V, for differing widths of pleatings. The
sides of the receptacle are heated by gas jets enclosed in cover casings W one on
each outer face for preventing undue escape of gas heat gas being supplied from
the branches X X and flexible tubing Y it being essential that heat be applied
to the machine during the pleating operation to sett" the pleats.
If the blades A, A, be set farther apart at one end of the machine than at the
other the pleats can be narrow and wide in their length.
I am aware of the Specification of Letters Patent No. 3597/89 granted to Howard
Trotman and I do not claim anything described and claimed therein. I am also

page_text: aware that pleating of fabrics has been effected by a machine somewhat of the
same construction as mine which however possesses many features of novelty in
detail such as, the adjustment screws, the slow back travel of the blades, the rapid
return, the plates by which the lift and throw back actions are obtained and the
appliances by which varying widths of pleatings can be effected, tend to render
the machine more serviceable for practical use and more reliable for the purpose
of pleating than any such machine hitherto made.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. In pleating machines, the screw bolt arrangement on the longitudinal shafts
for adjustment in lifting and in the back throw of the blades as described and
substantially as shown.
2. The improved pleating machine shown on the annexed drawings the parts
being arranged and acting in the manner and for the purposes explained.
