This invention relates to an automatic clear
ing device for a machine such as a numbering
machine or a device for printing or otherwise
applying identifying marks on materials. More
speci?cally the invention aims to coordinate the
operation of two machines so that when one
machine is manually actuated to carry out a
function the other machine also operates to carry
out a speci?c function in synchronism.

operation of a valve which is tripped by and
upon operation of the listing machine. Another
object of the invention resides in the provision
of a U-shaped member which is provided in an
inverted position over the numbering machine
to contact the numbersetting knobs in its sweep
over the machine to bring all the number print
ing wheels to the blank positions.
While this invention is applicable to many dif 10

and is not destroyed during the process of clean

two machines, one of which lists the articles and ,
the total number of each and the other stamps
or prints the assigned customer’s number on each
article. When all the articles have been entered
in the listing machineand the numbers applied
to the articles, the operator prints or records the
listing on a work sheet together with the cus
tomer’s assigned number. This operation locks
the listing machine which is independently
cleared and is then ready for the listing of a
machine, and

Only a number of the details of the listing

been illustrated on the drawing since any suit
able types of machines may be used and such
machines per se do not form any part of this
invention. For instance, a listing machine of the
type shown in Patent No. 1,695,964, issued De
cember 18,‘ 1928, and No. 1,103,063, issued July
14, 1914, and a numbering machine shown in
