48 Claims. (Cl. 209—110)
My invention relates to card filing or group
ing apparatus for use with what is commonly
known as record-controlled equipment.
One of the objects of my invention is-to pro
vide apparatus for grouping or bringing together

are commonly used with tabulating equipment,
which groups have previously been brought into
numerical or alphabetical sequence, the various‘

the claims, this structural detail and co-opera
tive mechanism has been referred to as value dif
ierentiating selective means. This means is con
. tinuously e?’ective for selectively causing ejec
tion of any one oi’ a plurality of records under—
going comparison, bearing a designation of a pre
determined value extreme, i. e., a high or low

quence, the apparatus serving to group the cards '
designating characters, or any combination of
into one common group arranged in consecutive
the designating characters of such series.
A further object of my invention is to provide
improved apparatus for withdrawing from a
group oi’ such cards arranged in numerical se
quence any desired selection oi’ cards.
A further object of my invention is to provide
apparatus for reassembling matched cards, some
of which cards have previously been withdrawn
from the‘ matched group.
A further object of my invention is to provide
apparatus for, assembling in a predetermined
In the various species shown, this value dif
i'erentiating selective means is combined with
structural detail and mechanism for conveying
the cards to a common receptacle and assembling
them therein in a common group in correct
numerical order. This structural detail and
mechanism is sometimes referred to in the claims
as correlating means and record handling means.
Heretoiore, data comparing machines designed
to accomplish certain selective disposition of
