Other objects and advantages reside in‘ the
construction of parts, the combination thereof
and the mode of operation, as will become more

Although this invention may be utilized with
any type of a writing machine or tabulating ma
chine wherein continuous length superposed
‘ strips of record material may be used, it‘ has been
shown for the purpose of illustration mounted on
a typewriter I 0 having a carriage l2 supporting
a platen I 4.

In the modi?cation shown the platen M in
‘ Aside from the gear mechanism lit, t8 and 50,
so as to present a suitable resilient surface to the
writing material, thereby providing a suitable
backing for the impingement of the type.
A pair of pin wheels ‘it, each provided with 35
a plurality of equally spaced feeding pins ‘l2, are
mounted for rotation upon a shaft ‘it ?xedly se
cured to a pair of crank arms ‘it, one of which
is attached to a pintle ‘i8 journalled in a suit
able recess in the end of the shaft- 28 and the
other attached to a shaft 80 extending through
the hub 22 and having one end thereof connected
to a lever 84, which lever is provided with a latch
85 suitably seated in a selected aperture 88 in
the side‘of the carriage frame i2.
,
The teeth 12 in the pin wheel ‘ID are arranged
to project through the openings 62 throughout
a portion of the periphery of the platen so as to
engage suitable apertures 90 in the margins of
the record material 92 to feed the several super
posed strips in registry past the writing position.
In addition to positively feeding the record mate
' rial 92 around the platen It, the feeding pins 12
accurately align the superposed strips‘ one with
the other, so that perfect registration is main 55
tained while passing the normal writing position.
The shape of the feeding pins ‘i2 is such that
as the pin advances through the apertures 62 in
the platen, the rear margin of the pin contacts
the rear portion of the aperture 62 and when
2
9,128,924
the pin 12 is retracted or is leaving the engage
ment of the record material the leading edge
thereof contacts a leading portion of the aper
ture 62 until the pin 12 clears the platen. This
$1 results in accurate alignment of the record mate
rial, as the leading arcuate surface of the feeding
pin,_remains in constant engagement with the
record material from the time it ?rst engages it
until the feeding pin is retracted in its entirety
10 from engagement with the record material.
Although the edges of the aperture 62 may be
utilized as the equivalent of gear teeth in the _
platen l4, meshing with the feeding pins 12 to
actuate the pin wheel 10 freely rotatable upon
the eccentrically mounted shaft 14, each of the
wheels 10 have been provided with externally
disposed teeth I00 meshing with the internal
teeth I02, projecting inwardly from the cylindri
cal shell I6, so as to secure accurate relative
movement between the pin wheel ‘I0 and the
platen It. In view of the fact that the pitch line
of the gear teeth I00 and I02 is substantially flush
with the surface of the platen I4, the peripheral
speed of the platen and the paper engaging por
tion of the feeding pins 12 is substantially equal,
so as to cause the record material while passing
the platen to travel at a speed substantially equal
to the surface feed of the platen.

ing devices normally found on typewriters and
‘other writing machines to frictionally feed writ
ing material past writing position, thus elimi
nating the necessity of providing a pin wheel
feeding device that is shiftable from operative
to inoperative position when it is desired to use
the typewriter or writing machine, as the case
may be, with record material or short length
writing material that is not marginally punched.
Although the preferred modi?cation of the de 10
vice has been described, it will be understood that
within the purview of this invention various
changes may be made in the form, details, pro
portion and arrangement of parts which gener
ally stated, consist in a device capable of carrying
out the objects set forth, in the novel parts, com
bination of parts and mode of operation, as dis
closed and de?ned in the appended claims.
Having thus described my invention, I claim:
1. In a writing machine for use with contin 20

terial having therein longitudinally spaced feed
holes, the combination of a rotary platen having
internally disposed teeth arranged in substan

said support, said pin wheel having a toothed

shifted in unison in that the mounting thereof, less than the diameter of the platen, sothat as
that is, members 14 and 10, together with the the gear is eccentrically disposed with respect to 35

the typewriter. When the pin wheel 10 is shifted terial to be fed in registry past the writing posi
from the dot dash position to the full line posi
tion of a writing machine, said record material
tion the conventional feeding device on the having therein longitudinally spaced feeding
typewriter may be used to actuate or feed the holes, the combination of a rotary platen having
writing material frictionally past writing posi
tion, as the feeding pins project beyond the pe
riphery of the platen at a point beyond the nor
mal path of the record material 92.
In the modification disclosed in Fig. 5 the
platen “0 has been schematically shown pro
vided with one pin wheel adjacent one end
thereof and a feed roller “2 also having a pin
wheel feed adjacent the corresponding end
thereof. The opposite end of the platen and the
opposite end of the roller H2 have not been pro
vided with pin wheel feeding devices. The
platen H0 and the roller H2 may be driven in
unison by suitable driving mechanism not shown.
In this modi?cation the record material 92 in
60
,stead of being aligned transversely while passing
the writing position, has one margin thereof ac
curately aligned and held taut while passing
writing position, thereby maintaining registry.
The platen may be mounted in the conventional
65 typewriter carriage and the aligning roller to
the rear thereof. The record material requires
‘ only one row of apertures or feed holes.
These
may be placed in the margin. If the pin feeding
device is mounted near the center of the platen,
70 ‘the aligned row of feed holes may then be cen
trally located.
If it is desirable to use record material that has
not been marginally punched, the portion of the
platen beyond the feeding pins may be used in
75 cooperation with the conventional friction feed
internally disposed teeth adjacent each end 45
thereof, with a pin wheel feeding device includ
ing an eccentrically disposed support mounted
within the platen and a pair of pin wheels
mounted thereon and having the pins ?xedly at
tached thereto for projection through a series 50
of circumferentially spaced holes in the platen
beyond the periphery thereof, said pin wheels

the teeth of the platen so as to rotate the pin
wheel feeding device with the platen as it is actu 55

spaced relatively ?xed radial pins intersecting
and projecting beyond a limited portion of the
periphery of the roll into feeding engagement in
the holes in the strips, and driving means for
actuating the pin wheel by the rotation of the
roller, but at a different speed of rotation.
28. A strip feeding means /for a writing or 55
ing progressive intermeshing engagement in the
holes of the cylindrical member and differentially
printing apparatus wherein a continuous strip
revoluble in unison therewith in a path of travel
eccentric thereto, during which rotation the in
60 termeshing pins are projected through succeed
ing holes in the cylindrical member into feeding
engagement in longitudinally spaced holes in a
an impression receiving position by progressive
strip of material being advanced thereby.
24. Strip feeding means for a writing or im
of record material having therein a succession
of longitudinally spaced holes is advanced past
engagement of pin type feeding means in said 60
holes, including‘ a roller relative to which the
strip is advanced, a rotary pin wheel Joumaled
within the periphery and intermediate the ends
of the roller in eccentric relation therewithrin
printing apparatus wherein a continuous strip eluding spaced relatively ?xed radial pins inter 65
of record material having therein a succession secting and projecting beyond a limited portion of
the periphery of the roll into feeding engagement
of longitudinally spaced feed holes is progres
in the holes in the strips, a concentric series of
sively advanced past an impression receiving po
sition, including a recessed roller relative to which teeth upon the pin wheel and an internal series
of teeth upon the roller‘ with which the pin
70 the strip is advanced, having therein a series of wheel teeth intermesh for transmitting unison
circumferentially spaced holes, a pin wheel lo
cated interiorly of the roller including a succes-'
slon of spaced relatively fixed radial pins eccen
trically intermeshing in the circumferential holes
