The present invention has relation to print
ing presses and the main object of this invention
is to provide a miniature press operating as a
useful and instructive toy.

are included whereby a comparatively inexperi
within the slideway or track holding the same
enced juvenile person may therewith‘effect print
ing on cards or sheets of a size within the
10 capacity of the press.
With this miniature press most of the parts
thereof are made of sheet metal stamped out
and so arranged and constructed that these parts
may be produced and assembled at a compara
15 tively low cost so that the press can be sold at
a low price as an operating and useful toy. The
construction and design of the press is such that
the packing and handling of the press is facili
tated. Furthermore, the design’ is attractive in
20 appearance which may tend to- materially aid in
the sale of the press.
'
The invention consists mainly of the particular
construction and arrangement of the component

whereby an even'impression can be obtained in
the printing operation.
It will be understood,
however, in a moreexpensiveform of the im-v 10
proved press metal type and a metal block would '
be employed so as to get :?ne adjustment for
better printing.

The improved press has the platen I6, which
is connected by a system-of links l‘! with the 15
inking roller l8 and operating lever IS in such
a manner that on ‘the upward movementfofisaid
lever the sheet on, the platen will'be brought in
contact with the type and in the same movement
the inking roller I8 is caused to- travelover the 20
inking pad Ill. When the lever I9 is brought
to its down position the inking roller picks up’
ink on the pad and inks the type for the next
impression. To insure perfect contact of the
parts or elements of the improved structure as
