Improvements in Paper Perforating Devices.
We, WILLIAM FRISBY WELLS, AARON D. WELLS, and LEWIS ROBERT
MARSTON Senior all of Cleburne, in the County of Johnson, and State of Texas,
United States of America, Gentlemen, 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 has relation to certain new and useful improvements in paper-
perforating devices adapted for ready attachment to printing presses, and more
particularly to small presses and wherein the platen is moved towards and from the
bed of the press, and the invention is designed to perforate paper at the same time
that the latter is being printed upon as for instance in the preparation of bank-checks;
promissory notes, etc., where there are several of the same contained on each sheet
separated by lines of perforations, and among the objects in view are to provide a
simple, cheap, and efficient construction of perforator of the character described
adapted to perforate paper longitudinally, transversely, and diagonally of the sheet
of paper and whose perforating bars are adapted for ready adjustment so as to vary
the distance between the lines of perforations, all as hereinafter fully described,
illustrated in the drawings and pointed out in the appended claim.
In said drawings
Fig. 1 is a plan view of the device.
Fig. 2 is an enlarged section taken on the line a—a of Fig. 1.
Fig. 3 is a like view taken on the line b-b.
Fig. 4 is a section of the bars A and showing the connection between the same.
Fig. 5 is a plan view showing a slight modification.
Fig. 6 is an elevation of portions of the bars D, E, separated from each other.
Fig. 7 is a detail perspective view of a portion of the bar D and one of its
releasing springs.
In the described drawings A designates the side bars which have their edges a,
beveled and are provided with bolt-holes a' for attachment to the rod X to which
the ordinary grippers are usually attached. This rod X extends transversely across
the face of the platen near its lower edge between said platen and the bed of the
press. Thus the perforator when attached to the rod X stands intermediate the
platen and the bed and in a position to be forced against the paper
laid upon
the platen to cause it to be perforated when said platen and bed are brought
together in the act of printing, the type held in the bed being projected between
the various perforator bars and coming in contact with the paper print it at the
same time that it is being perforated. B is a bar which near each end is thickened
at B' and cut away or beveled at the edges B so as to fit against the beveled
edges a, of bars A. 63 are nuts whose edges 6* are beveled to fit against the beveled
edges a, of bars A and said nuts are perforated to receive the securing screws b³
which pass up through perforations in the bar B. By screwing up the_screw
the bar B will be held securely in place but by loosening the screw the bar B may
be adjusted along the bars A.
C is a bar for connecting the ends of the side bars A to render them more rigid
and. to afford in conjunction with bar B a support for perforating bars. The bar C
is connected with the bars A similarly to the bar B that is to say, it is beveled at c,
to fit against the beveled edges a, and is secured to bars A by screws c³ passing
through perforations in bar C and nut c', the latter having beveled edge c fitting
against beveled edges a, of bars A. The bar C can thus be adjusted along bars A.
Fig. is a section of the bars A and showing the connection between the same.
Fig. 5 is a plan view showing a slight modification.
Fig. 6 is an elevation of portions of the bars D, E, separated from each other.
Fig. 7 is a detail perspective view of a portion of the bar D and one of its
releasing springs.
In the described drawings A designates the side bars which have their edges a,
beveled and are provided with bolt-holes a' for attachment to the rod X to which
the ordinary grippers are usually attached. This rod X extends transversely across
the face of the platen near its lower edge between said platen and the bed of the
press. Thus the perforator when attached to the rod X stands intermediate the
platen and the bed and in a position to be forced against the paper laid upon
the platen to cause it to be perforated when said platen and bed are brought
together in the act of printing, the type held in the bed being projected between
the various perforator bars and coming in contact with the paper print it at the
same time that it is being perforated. B is a bar which near each end is thickened
at B¹ and cut away or beveled at the edges B' so as to fit against the beveled
edges a, of bars A. are nuts whose edges * are beveled to fit against the beveled
edges a, of bars A and said nuts are perforated to receive the securing screws 6*
which pass up through perforations in the bar B. By screwing up the screw
the bar B will be held securely in place but by loosening the screw the bar B may
be adjusted along the bars A.
C is a bar for connecting the ends of the side bars A to render them more rigid
and. to afford in conjunction with bar B a support for perforating bars.
The bar C
is connected with the bars A similarly to the bar B that is to say, it is beveled at c,
to fit against the beveled edges a, and is secured to bars A by screws c³ passing
through perforations in bar C and nut c', the latter having beveled edge e fitting
against beveled edges a, of bars A. The bar C can thus be adjusted along bars A.

(Fig. 2).
D is a perforating bar extending transversely of the device and supported by and
adjustable along the bars B, C, in the following manner :-The bar D at its inner
end is provided with a tenon d³ which fits and is adapted to slide within a groove b¹
formed in one of the lateral edges of the bar B. The opposite end of bar D is
beveled on its under side to receive one of the beveled edges C¹ of bar C. d is a
nut having its inner edge beveled to fit against the other beveled edge C' and a
screw passes through perforations in the nut and bar C to secure the said bar D
in position after it has been adjusted along the bars B, C. Along the length of the
bar D are a series of perforating teeth or needles F which are wedge-shaped as
shown in Fig. 7. J are leaf-springs attached at one end to bar D and having their
bodies extending in a curved line upwardly above the surface of the bar, where
their free ends are broadened as at J. Upon the ends J¹ rests and is secured a
releasing bar H. The bar D may be used in connection with the side bars alone
when it is desired to make one line of perforations in a sheet of paper and in doing
so the springs J and bar H will, when the needles are pressed against the paper, be
pressed backward allowing the needles to puncture the paper. When the type
recede from the paper, the springs will be released and the bar H will press the
paper away from and off the needles. The bar H is provided with tongues h, which
pass down between the teeth F when the springs are depressed, thus guiding the
bar H in its downward movement.
When it is desired to perforate lines at right angles to that of bar D we use
a perforating bar E having a series of perforating teeth or needles G and leaf
springs K secured at one end to said bar upon the upper broadened ends of which
springs is secured a releasing bar I, which has tongues i, adapted to pass down
between the teeth G. The action of the springs K and bar I is similar to that of
the springs J and bar H above described.
The bar E is adapted to be adjusted along the bars A, D, and for this purpose it
is provided at its inner end with a tenon e' adapted to fit and slide in a groove d* in
one of the lateral edges of bar D and is beveled at e to fit against the beveled edge
of bar D (Figs. 3 and 6). The opposite end of bar E is beveled at the edge E¹ to
fit against the beveled edge a, of bar A. A screw e passes through perforations in
the bar E and nut e¹ to secure the bar E in position after it has been adjusted to the
desired position.
We
Instead of employing releasing bars H and I as above described they may be
dispensed with and the springs J K alone made to serve the desired purpose.
however prefer to employ said bars.
In using the invention we first attach the bars A to rod X as indicated, and then
adjust the bars D, E, to the proper points desired for perforating. Inasmuch as
the bars D and E are readily removable from the device corresponding bars of
different lengths can be substituted whereby different lengths of lines will be
perforated and if desired more than one bar D or E may be used, the additional
bars being readily placed in position in the device and thus a number of lines will
be perforated.
Or if desired, some of the perforating bars may be substituted by blank bars
such as B and C which do not perforate the paper.
Furthermore, the bars B may if desired be substituted by a perforating bar
constructed similarly to the bars D and E.
While we have described the device adapted to perforate paper on lines parallel
and at right angles to each other, it is evident that by a slight change in any of the
bevels of the attaching devices, lines may be perforated at any angle desired. Such
a construction we show in Fig. 5, there being no departure from the spirit of the
invention in such construction.
Although we prefer the means described for connecting the several bars of the
device with one another yet such means might be varied if desired, and we reserve
the right to the use of such modified means.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. In a device for perforating paper, the combination with the side arms of the
gripper, of a perforating bar or bars adjustable thereon, as and for the purpose
specified.
2. The combination with a perforating bar, of a releaser arranged along said bar,
a spring or springs beneath said releaser and connected to the perforating bar and
holding the releaser normally above the plane of the perforating teeth, said releaser
having tongues adapted to project between the teeth of the perforating bar, as
described.
3. The combination of the rigid side arms, with the perforating bars, said bars
being adjustable in relation to each other, and means for attaching the bars and
arms to one another, as described.
4. The combination of the bars A, with the bars B, C, and perforating bars
supported by and adjustable along the bars A, B, C, and means for securing the
perforating bars in position when adjusted comprising nuts adapted to clamp the
edges of the supporting bars and screws passing through the perforations of the nuts
and through perforations in the perforating bars the latter bars having beveled
edges adapted to clamp like edges of the supporting bars, as described.
