Drawings, and the like.
I, HERMAN JOFEH, of 21, Tudor Grove, Wells Street, Hackney, London, N.E.,
Engineer, do hereby declare the nature of my said invention to be as follows:-
The object of my invention is to effect improvements in or relating to apparatus
for obtaining copies of writings, drawings and the like from stencil sheets and
consists in an improved method of mounting and operating the stencil frame
and in the arrangement of the complete outfit for duplicating in a cabinet or
box,
According to my invention, I mount the working parts of the apparatus such as
the platen and stencil frame in a cabinet or box, and provide partitions or receptacles
for the stencil paper, printing paper, ink, roller and other articles or materials
used with this class of printing apparatus, the lid of the cabinet or box being
provided with an ink slab or distributing table fitted with a suitable removable
cover.
The stencil frame is mounted in a frame suitably hinged or pivoted to the
cabinet or box and the frame is provided with a finger or arm projecting downward,
the lower end of which is connected to a spring or a spring controlled rod fitted
in a cylinder suitably pivoted to the side of a cabinet or box. The spring is of
such a strength that the stencil frame is normally held in an inclined raised
position above the platen, whereby the printing paper may be readily laid on and
removed from the platen. The stencil frame is pressed down in contact with the
paper and the roller passed over in the usual manner.
The stencil frame is detachable from the pivoted frame, so as to facilitate
the application and removal of the stencil paper to or from the stencil frame.
This is effected by forming the pivoted frame with a recess of suitable
dimensions to receive the end of the stencil frame preferably by a sliding
movement.
The apparatus is so arranged that, when sufficient copies have been made the
materials and apparatus may be stored in their proper receptacles all together
in one cabinet or box, whereby, mislaying of portions of the apparatus is
prevented.

Drawings, and the like.
I, HERMAN JOFEш, of 21, Tudor Grove, Wells Street, Hackney, London, N.E.,
Engineer, do hereby declare the nature of my said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
The object of my invention is to effect improvements in or relating to apparatus
for obtaining copies of writings, drawings, and the like from stencil sheets, and
consists in an improved method of mounting and operating the stencil frame and
in the arrangement of the complete outfit for duplicating in a cabinet or box.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, in which similar
figures of reference indicate corresponding parts.
Fig. 1 is a plan view of the box as it appears when first opened for use.
Fig. 2 is a section of Fig. 1.
Fig. 3 is a section on the line a, b, of Fig. 1.
4 is the lower part and 5 the upper part of the cabinet or box in which the
working parts of my invention are mounted, the two parts being hinged together
at 6, 6, 7, 7, (shown by dotted lines in Fig. 1) are partitions, whereby the lower
part of the box is divided to form receptacles for stencil paper, ink, roller, and other
articles or materials used with this class of printing apparatus 8 is the stencil
frame which is removably mounted in the metallic frame 9. The frame 9 is
pivotted to the lower part of the box at 10, 10, on each side. The frame 9 is pro-
vided with a finger or arm 11 projecting downwards, the lower end being pivoted
at 12 to the sliding rod 13 of a spring contained in the cylinder 14, pivoted at 15.
The spring in the cylinder 14 draws the rod 13 inwards, and thus acts upon the
pivoted socket frame 9 in such a manner as to raise the stencil frame 8 to the
position shown in Figs. 2 & 3 above the platen 16 when pressure is withdrawn from
the stencil whereby the printing paper may be readily laid upon and removed from
the platen. The stencil frame is pressed down, together with the stencil, in
contact with the paper, and the roller is passed over in the usual manner.
stencil frame 8 is detachable from the pivoted socket frame 9 for the purpose of
facilitating the application and removal of the stencil to and from the stencil
frame, which is effected by a sliding movement. 17 is a folding cover fitted to the
upper portion 5 of the cabinet, covering the inking slab or distributing table 18.
The cover 17 can be raised and folded back, as shown by solid lines in Fig. 3, or
the flaps may be fitted with angle blocks 19 as shown by dotted lines in Fig. 3
for the purpose of using the outer leaf as a convenient table, as shown by dotted
lines in the same figure.
The
The arrangement of the apparatus and construction of the cabinet is such that,
when sufficient copies have been made, the materials and apparatus may be stored
in their proper receptacles all together in the one cabinet or box, whereby mis-
laying of portions of the apparatus is prevented.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
-
1. The improved apparatus for duplicating writings, drawings, and the like, 4
substantially as described.
2. In stencil and analogous printing or copying apparatus, the application and

page_text: use of a stencil frame detachably mounted in or on a pivoted frame, so arranged
that the stencil frame is normally held in an inclined raised position above the
platen by a spring or weight, substantially as hereinbefore described and illustrated
by the drawings.
3. The combination of a stencil frame, pivoted socket frame and platen, arranged
in a cabinet provided with an inking slab and a cover capable of being used as
a table, also with receptacles for the usual appliances, substantially as hereinbefore
described and illustrated by the drawings.
