I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my invention for "IMPROVEMENTS IN INKING APPARATUS FOR PRINTING
MACHINERY" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to apparatus for transferring stripes of printing-ink from
the ductor roller of a printing machine to the types.
In the apparatus heretofore employed for transferring ink from the ductor roller
the arrangement was such that, in order to obtain a wider or narrower stripe
of ink, the inking roller was alternately brought into contact with the ductor
roller for a greater or smaller length of time, according to the width of the stripe
of ink to be obtained.
The length of the said stripe of ink thus. taken off the ductor roller, however,
was always the same as that of the inking roller and would always remain the
same after having been transferred from the inking roller to the other rollers, and,
ultimately, applied to the types.
It is found desirable, however, in some cases, that only a portion of the inking
roller should take ink from the ductor roller and at certain places thereof.
In order to attain this end the said invention comprises the improvements
hereinafter described.
In the accompanying drawing,
Figures 1 and 2 are vertical sections of the said apparatus showing the inking
rollers in different positions.
Figure 3 is a front view of the said apparatus and
Figure 4 is a rear view of the same, partly in section.
Figure 5 is a plan view of a part of the said apparatus.
Instead of a single inking roller, as formerly, I employ a number of small
inking rollers w arranged adjacent to each other in such a manner as to form
a line of rollers of any required length. The said small rollers ware arranged

page_text: so as to slide in a frame S mounted on the shaft 8, each roller being journalled in a
small block a which slides in guides b of the frame S.
The blocks a are each provided with a set screw c passing through a slot d of
the guides b, and by tightening the said set screws the blocks a carrying the
rollers w may be held in position.
In the position shown in Figure 1 the small inking roller is set back so as not to
engage with the ductor roller D when the shaft s is rotated, or the frame S is
raised. In Figure 2 the small inking roller is drawn out, being held in such a
position, by means of the set screw c, as to engage with the ductor roller D, and,
when the shaft 8 is rotated, to take a stripe of ink, from the ductor roller every
time the frame S is fraised, the length of the said stripe- corresponding to the
number of the said inking rollers drawn out. On lowering the frame S; the
rollers ware also lowered, all those which have been in contact with the ductor
roller D transferring ink to the roller w'.
It will thus be seen that a stripe of ink of a given length may be obtained by
drawing out the requisite number of inking rollers.
J
Having now particularly described and ascertained the nature of the said
invention, and in what manner. the same is to be performed, as communicated to
me by my foreign Correspondent I declare that what I claim is
1
The employment of a number of inking rollers arranged adjacent to each other
and capable of being drawn out and set back independently, only those rollers
which are drawn out taking ink from the ductor roller, so that a stripe of ink is
conveyed corresponding in length to the number of the said inking rollers drawn
out.
