JESSE AUSTIN GREENWALT, OF GALVESTON, TEXAS.
TAPE FEEDING AND C ECING REGISTER.Specification of Letters Patent. Patented Mar. 30, 1920.
Application filed October 22, 1919. Serial No. 332,384.To all whom it may concern,:
Be it known that I, JESSE A. GREENWALT,
a citizen of the United States, and a resident
of Galveston, in the county of Galveston and
5 State of Texas, have invented a new and Im-
proved Tape Feeding and Checking Regis-
ter, of which the following is a full, clear,
and exact description.
The present invention relates to a tape-
10 feeding and checking register, and has ref-
erence more particularly to a device of this
character in which successive characterized
portions of a tape are exposed through an
opening in the device, with means for check-
15 ing or indicating the portions of the tape
thus exposed.
The primary object of the invention is to
provide a device with which a tape, includ-
ing numbers or other characterized features,
20 may be checked or compared to verify the
correctness of the numbers, or other char-
acterized features of the tape.
In its preferred embodiment, the inven-
tion finds expression in a device which is
25 specially adapted for comparing the num-
bers of adding-machine tapes to verify the
same with the figures represented on the
text from which the figures were copied by
the adding machine.
30 As heretofore practised in banking institu-
tions and other establishments where adding
and calculating machines are employed, it
has been customary to verify the figures
copied on the machine tape with the text,
35 to check up mistakes. The method usually
resorted to in comparing these figure tapes
was to have them proof read by one or two
persons. This method, while satisfactory in
so far as concerns the result of the compari-
40 son, is impractical in that it requires either
two persons' time or. an undue hardship on
one person. According to the preferred em-
bodiment of the present invention, the fig-
ures of the tape may be verified with the
45 text by a single person and without impos-
ing a hardship on the person.
The device is illustrated in the accompany-
ing drawings, in which-
Figure 1 is a top plan view of the device;
50 Fig. 2 is a side elevation;
Fig. 3 is a cross section on the line 3-3
of Fig. 1;
Fig. 4 is a longitudinal section on the line
4-4 of Fig. 1;
55 Fig. 5 is a sectional view of the tape-checking means taken on the line 5-5 of
Fig. 1;
Fig. 6 is an enlarged detail view of a part
of the tape-feeding means; and
Fig. 7 is a sectional view on the line 7-7 60
of Fig. 6.
Referring now to the drawings in detail,
the device preferably embodies .a relatively
long casing 1 providing a tape holder
through which the tape A is longitudinally 65
fed, the same entering the casing or holder
through an opening 2 in the slanting front
wall 3, from where it passes over a suitable
platen 4 positioned adjacent the face or top
5 of the casing. The tape is passed over and 70
fed through the holder by frictional contact
with a rotatable roller 6 located in the oppo-
site end of the holder and over which the
tape passes to the opening 7 in the slanting
back 8 of the device. To insure proper fric- 75
tional contact of the tape with the roller 6,
a pair of oppositely-spaced friction-inducing
rollers.9 and 10 are supported over the roller
6 and adapted to maintain the tape in con-
tact with the roller 6. These rollers are 80
mounted, with freedom of rotation, on suit-
able spindles 11 and 12 which are, in turn,
journaled in suitable bearings, the spaces be-
tween the bearings being bridged by strips
13. The friction rollers are supported over 85
the roller 6 by the levers 14 which- are piv-
oted to the casing, as at 15, and to the strips,
as at 16. Coil springs 17 are connected to
the levers 14 and to the casing to maintain
the friction rollers against the tape under 90
tension.
To release the friction rollers from con-
.tact with the tape, a rocking lever 17'.is
pivoted to the casing, as at 18, and adapted
to swing about its pivot to manipulate the 95
levers 14 to raise or lower the friction roll-
ers. The tape is fed through the holder
in a step-by-step manner, to which end the
roller 6 is provided with a co-axially-
mounted ratchet 18, the teeth of which are 100
disposed at an angle to the axis of rotation
of the ratchet, whereby they may receive a
suitable ratchet 19, which is pivoted as at
20, with a hooked end 21 disposed in a po-
sition to successfully engage the ratchet .105
-teeth and rotate the roller. The manipulat-
ing means for the pawl comprises a lever
22, one end of which is pivoted, as at 23,
with a pivot point also provided at the
pivot 20 of the pawl 19. A spring 24 con- 1101,335,576.
