Improvements in Apparatus for Use in Producing Copies of
Writings, Drawings, and the like.
EUGENIO DE ZUCCATO of 15 Charterhouse Street, in the City of London, do
hereby declare the nature of this invention to be as follows:-
My invention is designed to improve the construction and increase the efficiency of
the apparatus described in the specification of former Letters Patent granted to me
and dated 29th September A.D. 1877, No. 3647, for holding stencils during the
operation of producing copies of writings, drawings or the like by the process set
forth in the said specification.
The said apparatus, as hitherto constructed, comprises a frame having connected
thereto by means of hinge-joints two metal bars which fit into grooves in the said
frame for the purpose of holding and stretching the stencil thereon. The said frame
is, moreover, provided with hooks for securing the said bars in the said grooves.
A board is connected at one of its edges by means of hinge-joints to the said frame
and is supported at its opposite edge by a lever pivotted to the said frame and
provided with a handle whereby it may be turned in either direction. This board is
arranged between the said metal bars beneath the stencil, and serves for supporting
the sheet of paper on which the copy or facsimile is to be produced. By turning the
said lever in one direction, the said board may be lowered or inclined to permit the
introduction of the paper between the same and the stencil, and by turning the said
lever in the reverse direction, the said board may be raised to bring the paper into
contact with the under surface of the stencil.
According to one part of my present invention, I adapt the said apparatus for
holding or containing the india-rubber scraper, the bottle of ink or other articles
required in the process of producing the said copies. For this purpose I make the
said apparatus in the shape of a box, the stretching frame forming the sides and the
hinged board serving as the lid of the said box. By this means I am enabled to
dispense with the box which has heretofore been supplied for containing the said
apparatus, the scraper and the other articles required for use therewith. I thus
reduce the cost of the entire apparatus and make the same very compact.

page_text: According to another part of my present invention, I make the front portion of the
box movable and connect the same by means of hinge-joints to the bottom of the
box, and I provide the said front portion with one or more curved projections or cams
on its inner side. The front edge of the aforesaid board rests upon these cams or
projections, which are so formed that, by turning the said front portion upon its
hinges in one or the other direction, the said board may be raised or lowered for the
purposes above specified. By constructing the apparatus in this manner I am
enabled to dispense with the aforesaid lever.
I prefer to make the said front portion with extensions at each end thereof, which
extensions project above the top of the box and are formed with vertical slots or
grooves, and I make the aforesaid metal bars of such length that their free ends fit
into the said slots or grooves when the apparatus is ready for producing a copy.
I thus provide in a very efficient manner for preventing lateral displacement of the
said bars.
By my present improvements the operation of producing the copies is greatly
facilitated and the entire apparatus can be made more compact and produced at a
lower cost than heretofore.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Use in Producing Copies of
Writings, Drawings, and the like.
1, EUGENIO DE ZUCCATO, of 15 Charterhouse Street, in the City of London,
Manufacturer, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
My invention is designed to improve the construction and increase the efficiency of
apparatus of the kind or class described in the Specification of former Letters
Patent granted to me and dated 29th September A.D. 1877, No. 3647, that is to
say, apparatus for holding stencils during the operation of producing copies or
facsimiles of writings, drawings or the like by the process set forth in the said former
Specification.
Such apparatus, as hitherto constructed, comprises a frame having connected

page_text: To provide for effectually preventing lateral displacement of the bars D, I some-
times employ slotted or notched metal pieces e which are secured to the ends of the
box so that they extend upward above the same and so that the bars D, when in their
grooves, will fit into the slots or notches in the said metal pieces e as shown in
Figure 2. In other cases, I make the front portion of the box with extensions at
each end thereof, which extensions project above the top of the box and are formed
with vertical slots or grooves, and I make the bars D of such length that their free
ends will fit into the said slots or grooves when the said bars are in the grooves in
the box A.
The hinges of the lid B are so made that the said lid may be opened to permit the
placing of the scraper, the bottle of ink and other articles in the box.
The apparatus is, in some instances, constructed with a frame substantially as
described in the said former Specification, the front portion being hinged and
provided with a projection or cam substantially as, and for the purpose, herein
specified, and the lever described in the said former Specification being dispensed
with.
.
By my present improvements, the operation of producing the copies or facsimiles
is greatly facilitated, and the entire apparatus can be made more compact and
produced at a lower cost than heretofore.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I wish it understood
that I claim :-
First An apparatus for the production of facsimiles of writings, drawings or the
like, which apparatus is so constructed that it will serve as a box for containing
articles required in the production of the said facsimiles.
Second The employment of the hinged front portion of the box or frame having
the projection or cam, substantially as, and for the purpose, set forth.
Third The improved apparatus constructed substantially as described with
reference to the accompanying drawing for the purpose specified.
