Application November 25,1933, Serial No. 699,647
11 Claims. (01. 197-127)
The present invention relates in general-1 to
bookkeeping machines in which the paper is fed;
from in front, and down past theplaten, and;

more particularly to front feed means which; are
swung from a paper-holding position against. the
platen, to a paper~releasing position away from
keeping machine is diagrammatically indicatedv 5,

In the paper-releasing position it sometimes
happens that the front feed means tends to inter
,fere with the printing operation as a consequence
Referring to the drawing, a Sundstrand book:

damage would possibly result. It is accordingly swing in a counter-clockwise: direction under; the
usual to. provide a motor bar lock, or other dis
abling means, to prevent a printing operation
when the front feed means is in this paper
releasing position.
There are some bookkeeping operations how
ever, in which it is desirable to retain one of a
plurality of work pieces in the .machine for a
second, and sometimes subsequent operations, as
for example, a tally roll; the front feed means
being moved to paper-releasing position at the
conclusion of each working excursion of the
paper carriage to permit removal of the re
mainder of the work pieces.

jecting upwardly from a lever I3. The lever I3
is pivoted at It onthe frame I, and pivotally con

pin and slot connection at IT with a rigid part of

the frame I and terminates in a forwardly ex
tending nose II. A spring I9 connected to the
motor lock lever It at ill-tends to slide the nose
It is therefore an object of my invention to
provide means to automatically unlock the motor
bar as an incident to movement of the carriage

Another object is to provide means for defeat

of the motor bar, is effective to establish an elec
tric circuit to a driving motor, (not shown) but it

The front feed means includes, in this instance, a
parent from the following detailed description,‘ frame comprising a pair of side arms 28 mounted

Displacement of ‘
the side arms from the pivotal axis is normally
prevented by pins 32, fixed to the carriage in
position to act against the lower rear edge of the
arms to hold the latter in bearing engagement
with the cross rod II. The free ends of side arms
28 are rigidly connected for unitary movement

The preferred form of my invention is em 'from the front of the machine, or from the left,

‘
In some forms of bookkeeping operations, a
'25 plurality of work pieces are simultaneously in
serted in the machine and one or more of them,
such for example as a tally roll, are retained for
two or more machine operations, the remainder
of the work pieces, such for example as ledger
30 sheets,'being changed at the conclusion of every
complete excursion of the carriage.
Although it is necessary to prevent operation
of the machine while the frontfeed means is in
claims.
I claim as my invention:

said carriage, front feed means on said carriage,
said front feed means being movable from paper
holding to paper-releasing position and includ

ing a part co-extensive with the length of the
platen identified with the first mentioned-work
piece which tends to obstruct the printing means
when the front feed means is in paper-releasing
5 position, and a part which provides clearance
between the printing means and the front feed
means when the length of the carriage identi~
?ed with the second mentioned work piece is in
printing position, means tending to block the
10 manipulative means when the front feed means
is in paper-releasing position and the carriage
