We, HARRY STANLEY GRIFFIN, of Dudley, Camden County, State of New Jersey,
Manufacturer, CEPHAS ROSS CARVER, of No. 25, North Seventh Street, Phila-
delphia, State of Pennsylvania, Manufacturer, and HOWARD STOKES HEWSTON,
of No. 319, North Front Street, Camden, State of New Jersey, Machinist, all in
the United States of America, 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 the following statement:-
This invention relates to certain improvements in perforating machines and
particularly to the class known as rotary perforators for providing divisional
lines on sheet paper for use as checks, receipts &c. for the purpose of rendering
their separation easy.
The main object of our invention is to provide an improved construction of
dies for use in machines of this character, and means whereby the accurate adjust-
ment of the perforating needles may be quickly accomplished so that they will
act on the paper to perforate lines of different lengths.
A further object of our invention is to provide means for rendering any desired
number of intermittent needles inoperative in order that the line of perforation
may be broken to provide for the stub of the check, receipt, or other article, as
may be desired.
A still further object of our invention is to provide an improved form of per-
forating needle together with an improved means for securing it in the die.
With these principal objects in view our invention consists in the construction,
combination and arrangement of parts such as will be hereinafter fully described
and particularly pointed out in the claims made hereto.
In order to enable others skilled in the art to which our invention appertains
to make and use the samo we will now proceed to describe it, reference being had
to the accompanying drawings in which:

In carrying out our invention we provide a suitable supporting frame as A,
which may be of any desired form and constructed of any suitable material. On
the front side of the machine we provide a suitable feed table as B, which may be
secured to the main frame, A, by means of the bracket, b, or in any other suitable
and practical manner. A pair of feed rollers, C, C¹, are located at the end of this
feed table, B, for feeding the material to the revolving dies, the lower roll, C¹,
being mounted in stationary bearings provided in the frame, A, and the upper
roll, C, being provided with movable bearings and means for automatically raising
and lowering the same and operating a gate, so that the paper may be fed evenly
between the rolls and then firmly gripped and delivered to the perforating dies.
This is accomplished by providing a rocking arm as D, on one side of the
machine, pivoted to the frame at d, and carrying the said roller, C, in its forward
end. The rearwardly extending end of the arm, D, carries a stud roller, d',
adapted to engage a cam, E, mounted on the upper driving shaft, F, the revolu-
tion of said shaft tending through the medium of the said cam, E, to rock the
arm, D which raises and lowers the feed roller, C, at the proper intervals. This
arm, D, also carries the gate, c, which consists of a series of fingers carried by
the rod, e, and having their forward ends bent at right angles to form a stop
for the paper. When the roll, C, is raised by the action of the cam, E, the gate, o,
also rises, the bent portions of the fingers presenting themselves above the surface
of the roll, C, and the plane of the feed table, thus forming a stop against which
the sheets of paper may be evenly fed. Upon the drop of the feed roll, C, the
gate, c, also drops, alots, c, being provided in the lower roll, C¹, for the admission
of the fingers of said gate, c, and the paper is then gripped and fed by the fric-
tional contact of the two feed rolls, the lower one, C, of which is driven by
suitable gearing connected with the main driving shaft of the machine, thus feed-
ing the material to the perforating devices which will now be described.
In the frame, A, are mounted in suitable bearings an upper and lower driving
shaft, F, G, respectively provided with suitable intermeshing gearing the lower
or main driving shaft, G, carrying a belt pulley which may be connected with
the source of power. On the upper shaft, F, are located the male dies, H, which
carry the perforating needles, and which are keyed on the said shaft at suitable
intervals, and are capable of lateral adjustment by means of the set screws, h.
This male die, H, consists of an annular disk, H, having a suitable hub formed
around its central bore, for attachment to its driving shaft. On one side of this
disk, H³, is formed an annular shoulder or reduced portion, h¹, for the reception
of an annular ring, I, which is secured to said main disk by means of suitable
bolts as shown.
On the inner face of the reduced portion, h¹, is formed an annular groove or
channel, H, having in its upper end a narrow supplemental channel, ³, and on
the inner face of the ring, I, is formed a similar channel, I', which registers with
the channel, H³, when these parts are bolted together thus forming an annular
chamber as illustrated in Figs. 2 and 8 of the drawings. A series of slots, i, are
formed in the ring. I, opening into its channel, I', and of an equal distance apart,
adapted to receive the adjusting screws, J.
Located in the chamber formed by the channels, H³, and I, are a series of
segmental plates, L, snugly meeting at their ends and entirely filling one of the
said channels, H or I'. Each of the said plates, L, are provided with screw-
threaded openings adapted for the reception of the screws, J, by means of which
they are adjusted backward or forward to raise or lower the perforating needles, M,
as will presently be described. The upper left hand edges of the plates, L, are
beveled as at 7, and most clearly illustrated in Fig. 7 of the drawings.

page_text: The inner faces of the disk, H¹, and ring, I, between their channels and their
peripheries are provided with radial V-shaped grooves, m, which form when put
together diamond shaped openings (illustrated in Fig. 5 of the drawings) for the
reception of the perforating needles, M.
The perforating needles, M, are made substantially diamond shaped in cross
section having their lower ends bent at right angles to form substantially
L-shaped needles and are held in the diamond shaped openings, m, their lower
angular extensions entering the supplemental channel, h, of the channel, H.
When the needles are in operative position, as illustrated in Fig. 2 of the
drawings, they are supported and held against the upper wall of channel, h³,
by the segmental plates, L, and their operating screws, J. Should it be desired
to render a series of said needles inoperative the segmental plates are worked
from under the needles by operating their respective screws which allows said
needles to become yielding the supplemental channel, h, which received their
angular ends preventing them from dropping out as the die revolves, see Fig. 8
of the drawings. When it is desired to render these yielding needles again
operative the screws, J, are operated which works their respective segmental
plates under the said needles, the beveled edges, 1, coming in contact with the
corners of the needles and forcing them out, said plates serving to securely hold
them in this position.
The screws, J, are each provided with a collar, j, pinned or otherwise secured
thereon, over which fits a retaining ring, N, provided with slots, n, corresponding
to and registering with the slots, &, of the ring, I, and through which the outer
ends of the screws, J, project. This ring, N, is secured on the ring, I, by means
of suitable screws located between the slots as shown. A suitable milled head is
provided on the projecting ends of the screws, J, for operating them.
On one side of the male die, H, we provide a scale as o, illustrated in Figures 1
and 3 of the drawings. In operation the initial step is to adjust a set of needles
in operative position a distance corresponding to the length of the line to be per-
forated which may be easily determined by referring to the scale, o, then providing
for the intermission in said line by rendering inoperative a series of needles
corresponding to the desired length of said intermission, see Fig. 1 of the draw-
ings, in which the needles are set to perforate five inch lines and leave three inch
intermissions.
The segmental plates are capable of lateral adjustment by means of their
screws, J, and slots, i, so that it will be readily seen that the needles can be
adjusted to perforate any length of line or any length of space, as may be desired.
The female die, P, consists of two circular disks, p, p, bolted together leaving
a space between them of a sufficient width to admit the perforating needles of
the male die, which may be accomplished by interposing washers, 2, on the con-
necting bolts, 23, between the disks, p, p, or by any other practical manner.
These female dies are keyed on the lower driving shaft, G, in the same manner
as the male dies, and are capable of lateral adjustment on said shaft by means
of set screws, g. A number of openings as 7, are provided in the disks, p, p²,
so that the clippings falling from the perforations may easily escape and not
clog up the said female die.
On the periphery of the male die, H, are secured a pair of annular rubber
rings, r, held in grooves formed in said periphery as illustrated in Figure 2
of the drawings. These rings, r, are in frictional contact with the surface of the
lower female die, and serve to securely hold and feed the paper during the process
of perforation.
The strippers ass, are also provided for pulling the paper off the perforating
needles, which consist of a series of spring fingers carried by a transverse rod, st,
which are located above the paper and serve to pull the same off the perforating
needles and guide it under a pair of feed rollers, T, T¹, from thence it is delivered
to a receiving table or chute, U.
In describing our invention we have described and illustrated it in its relation

page_text: principally to a rotary perforator to which it is well adapted, it is clear, however,
that the invention is applicable and may be used upon perforating machines of
other classes than rotury perforators, for instance our improved perforating
mechanism may be used upon hand perforating machines. It is quite evident
that the construction of the machine to which our invention may be applicable
as herein described may be varied without departing from the spirit of our inven-
tion.
