PROVISIONAL SPECIFICATION.
Improvements in or relating to Apparatus for Perforating or Blind
Marking Cheques and other Papers.
I, EUSTACE SLOPER, of Tower Royal Works, West Hampstead, Middlesex,
Perforating Machine Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in or to apparatus for perforating or
blind marking cheques and other papers.
For the purpose of my invention, I cast or otherwise make a circular box with
an offset. The box carries a disc, in or near the periphery of which is a series of
shoulders for supporting or holding pins, the lower ends of which having the
perforating or stamping dies, and with the upper encircled by tension springs to
lift the dies. The disc is affixed to a handle movable over a plate provided with
holes for fixing the handle at any desired point, and according to the perforator or
stamp to be acted upon. The handle has a flat spring engaging the nose of the
handle catch pin to temporarily fix the handle.
I employ a transverse shaft encircled by a spring, and one part of the shaft has
projecting cheeks, between which a plunger bar is pivoted and pressed on by a
small spring to set it square with the cheeks.
The outer end of the transverse shaft has a lever for depression by the hand
to give the required pressure on the die plunger.
This lever is in connection by a slotted link with a paul for operating a ratchet
for moving the paper along after the perforating or stamping has been effected.
The offset has a stop piece for the paul to bear against, and so lock the paul in
the tooth of the ratchet when thrown down. The pressure on the paper is by a
spring roller from under the table of the offset.

COMPLETE SPECIFICATION.
Improvements in or relating to Apparatus for Perforating or Blind
Marking Cheques and other Papers.
I, EUSTACE SLOPER, of Tower Royal Works, West Hampstead, Middlesex,
Perforating Machine Manufacturer, 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 improvements in or relating to apparatus for perforating
or blind marking cheques, and other papers.
For the purpose of my invention and as shown in the annexed drawings, I cast
or otherwise make a circular box A with an offset B. The box A carries a
disc C in or
near the periphery of which is a series of shoulders D, D, for
supporting or holding plungers E, E, the lower ends of which have the perforating
or stamping dies F, and with the upper encircled by tension springs G to lift the
dies F. The disc C is affixed to a centre post H movable over a plate I by a
handle J, said plate I being provided with holes K to enable the handle J to be

page_text: fixed at any desired point, and according to the perforator or stamp to be acted
upon. The handle has a flat spring L engaging the nose of the handle catch pin M
to temporarily fix the handle.
I employ a transverse shaft N encircled by a spring P, and one part of this
shaft has projecting cheeks Q, between which a plunger bar R is pivoted. The
outer end of the transverse shaft N has a lever S for depression by the hand to
give the required pressure on the die plunger. E through the intermediation of the
cheeks and plunger R. This lever S is in connection by a slotted link T with
a paul U for operating a ratchet V for moving the paper along after the
perforating or stamping has been effected.
The offset B has a stop piece W for the paul U to bear against, and so lock
the paul in the tooth of the ratchet V when thrown down.
The ratchet shaft X has a resistance roller Y and another roller Z acts under
the action of the spring a to give the required pressure for retaining the paper in
position after being lodged in the slot b, said spring a also serving as a lever to
enable the roller Z to be lowered for the ready insertion of the paper.
By the arrangement of the ratchet mechanism a depression of the lever S causes
the paul to slide over a tooth of the ratchet wheel V and the selected die to
perforate the paper with the mark or symbol corresponding to that at which the
handle J had been moved and temporarily fixed by the spring and catch L, M, the
return movement of the lever S effected by the spring P compels the paul U to
force the ratchet wheel V and roller Y round the distance of one tooth so that
by the pressure on the paper by the roller Z it moves along a corresponding
distance for automatically spacing and placing the paper in position for the next
depression of the lever S for a fresh marking.
It will be observed from the drawings that the die plate c and guide plate d
are moved as one at each motion of the handle J and these plates are kept in close
contact by screws e, e, which serve for adjusting the level of the plates and to
receive the pressure caused by the perforating.
The shaft N is out of the centre and the divided arm Q projects to the centre
but not near the central shaft H, and said plunger R is pivoted and located between
the two cheeks Q, Q, to follow a straight down motion without putting side
strain on the plunger E when under depression.
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. The improvements in or relating to apparatus for perforating or blind
marking cheques and other papers, as hereinbefore described.
2. In a perforating or blind marking machine for the purpose described, loosely
pivoting the plunger R to the cheeks of an extension from the shaft N, as set
forth and as shown.
3. In a perforating or blind marking machine, the employment of a slotted
link T between the hand lever S and the ratchet U in conjunction with the paul
and roller appliances for the purposes explained and as shown in the annexed
drawings.
