I, THOMAS JAMES HEAP, of 54, Mill Street, Hanley, Staffordshire, Bookbinder,
do hereby declare the nature of this invention to be as follows:
-
This invention relates to an improved machine for perforating paper, such as
bills, receipt forms and such like, for the purpose of enabling a portion of the
same being torn off or separated from the other portion.
The said machine consists of a frame or standard provided with a board or
table for receiving the papers and fitted with side brackets which support two
cross-bars, one above the other.
:
The upper bar which is supported by a frame sliding in the brackets carries
one or more shaped pieces or brackets in the lower edge of which are fixed
the perforating pins. The lower bar carries a similarly shaped piece or pieces
forming the bed into which the pins pierce.
The bars are passed through rectangular holes in the T shaped pieces or
brackets, the bars being also rectangular to fit the holes, and any number of
the said pieces or brackets can be fixed in the required positions upon the bars
by means of set screws.
:
The support of the upper T pieces or brackets is connected by vertical rods
to a treadle fitted to the frame or standard for giving the reciprocating vertical
motion to the perforating pins.
!
The said pieces or brackets are for the purpose of forming the lines of per-
forations at right angles to the vertical line of perforations on the paper which
line is formed by pins fixed to the lower edge of one of the sides of the move-
able, or reciprocating support or frame extending across the machine.
.
Thus by means of my invention the whole of the division lines on a sheet
are perforated at one operation or stroke of the machine.

page_text: to be performed, to be particularly described and ascertained in and by the
following statement:—
This invention relates to an improved machine for perforating sheets of paper
forming bills, cheques, receipt forms and such. like for enabling a portion of the
same being torn off or separated from the other. portion.
The machine comprises a frame supporting a table for receiving the papers
and fitted with side brackets supporting two cross-bars one above the other. The
upper bar is supported by end frames sliding in guides on the brackets and
carries one or more T-shaped pieces or brackets in the lower edge of which are
fixed the perforating pins.
The lower bar, which is supported by the side frames, carries a similar nuniber
of pieces forming the beds into which the pins pierce. The said pieces or brackets
are fixed to the bars in the required positions by means of set screws, and they
are carried at right angles to the line of pins running across the machine and
forming the vertical line of perforations upon the sheets of paper. The supports
of the upper T-pieces or brackets are connected by vertical rods to a treadle fitted
to the frames for giving the requisite vertical motion to the pins in the usual
manner.
In the accompanying sheet of drawings
Fig, 1 is a vertical cross section of the machine and Fig. 2 is a plan thereof.
Figs. 3 and 4 are side and plan views, to a larger scale of the "knocker off" for
removing the paper from the pins, and Fig. 5 shews a sheet of paper with the
perforations formed therein.
a are the side frames of the machine and b is the table. c c are the side brackets
fixed to the frames, and d, dare the end frames carried by the guide-pieces e, e¹
sliding in the guides f, fl. g is the upper bar, which as shown is of triangular
section, and is supported in similar shaped openings in the frames d, d. h are
the T-shaped pieces or brackets carried by the said bar and fixed thereto by the
set-screws h¹, and are the perforating pins fixed to their lower edges. k is a
metal block fitting in a space formed in the brackets h and which is removed for
giving sufficient play for fixing the pins to fit the perforations in the beds.
1 is the lower bar supported by the frames, and carrying the lower pieces or
perforated beds m which are fixed thereto in line with the brackets h by the set-
screws m¹.
The pins forming the vertical line n of perforations, see Fig. 5, are carried by
the cross bracket o in the usual manner, and this bracket as well as the brackets h,
forming the perforated lines #1, is supported and operated by the vertical rods p
by means of cranks q operated by a treadle in the usual manner.
To prevent the paper sticking to the pins after it has been perforated, steel
strips are carried by a cross-bar s and caused to engage with the pins by means
of a slit r, Fig. 4, a little wider than the pins, the said strips bearing upon the
paper and preventing its rising with the pins.
As will be seen the brackets and o carrying the pins are operated simul-
taneously as one piece, and consequently the perforated lines n and n¹ are all
punched at a single operation of the machine.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what
I claim is:-
(1) The improved machine for perforating sheets of paper to form bills, receipt
forms and such like comprising a frame or bracket carrying the pins forming the
vertical line of perforations, and frames or brackets carrying the pins forming the
horizontal lines of perforations and supported by a cross-bar carried by end
frames sliding in guides in side brackets, the said pins entering holes in beds
or T-pieces supported by a lower cross-bar, substantially as described.
(2) In machines as above claimed the combination of frames or brackets carry-

page_text: ing pins, and perforated beds arranged at right angles to one another, steel strips
for removing the paper from the pins, and means for operating the machine so
as to punch the whole of the perforated lines simultaneously substantially as
described.
