Improvements in the Knives and Knife-blocks Employed in
Trimming the Bars of Type for "Linotype" and other like
Machines.
I, MATTHEW HENRY WHITTAKER, of 58 Whitefriargate, Kingston-upon-Hull
in the County of York Mechanical Engineer, do hereby declare the nature of this
invention to be as follows:-
The object of this invention is to enable a capital letter to be used at one end
of a bar of type cast in a "Linotype" or other machine of a similar class, which
capital letter projects downward to a depth equal to two lines of ordinary type,
for instance the letter "
in the word " ANTED."

In order to carry out this invention the principal alterations effected and herein
described are in the knife-block and in the knife which is employed in trimming
and truing up the parallel sides of the bars of type when cast.
For this purpose, to admit and trim up a bar of type, which is cast with a
capital letter projecting downwards at one end, to a depth equal to two lines
of ordinary type, a part of the knife-block and of the knife is severed within a
suitable distance of one end, the severed portion being equal in width to that of
a capital letter.
This severed portion of knife-block and knife, or their
equivalent, is mounted upon a stud or pin attached to the main knife-block, and
provided with a hand lever, by turning which a quarter of a circle the movable
parts above mentioned are thrown out of line and away from the stationary
portion of the knife and block, whereby a gap is left into which the lower part of
the capital letter projects without hindrance, while the narrower and parallel
portion of the type-bar is trimmed by the fixed part of the knife.
Upon turning back the before named hand-lever the knife assumes its original
position for trimming ordinary single line bars of type.

Improvements in the Knives and Knife-blocks Employed in
Trimming the Bars of Type for "Linotype" and other like
Machines.
I, MATTHEW HENRY WHITTAKER, of 58 Whitefriargate, Kingston-upon-Hull
in the County of York, Mechanical Engineer, 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 :-
The object of this invention is to enable a capital letter to be formed at, one
end of a bar of type, cast in a linotype or other machine of a similar class, which
capital letter projects downward to a depth equal to two lines of the ordinary size

page_text: In order to enable this invention to be fully understood, I will proceed to
describe the same with reference to the accompanying drawings in which,
Figure 1 represents a front elevation of a knife and knife-block which are
adapted to be employed in a "Linotype" machine, acccording to my improvements,
for the purpose of trimming up and dressing off rough or projecting irregularities
from the sides of bars of type formed therein.
Figure 2 represents a side elevation of the sanie.
Figure 3 represents a frout elevation of the knife and knife-block similar to
Figure 1-but with the pivotted cutter and crank handle removed.
Figure 4 represents a transverse section of the knife and knife-block at the
plane xx.
Similar letters refer to similar parts in all the drawings. The knife-block is
represented at A A and the knife at B B which has its cutting edge at C C.
Hitherto the bars of type produced in a "Linotype" machine have been formed
with two sides parallel and have when cast been passed between two straight and
parallel trimming knives, but in order to allow the passage and trimming of a bar
of type such as H J, at one end of which a two-line capital H projects, a portion
of the knife is cut away, so as to form a gap or recess and a short knife blade D
mounted upon a shaft E E is provided, which short knife blade can be shut by
means of the crank handle F close up to the main portion of the knife B B or
opened away from it, as shown in dotted lines Figure 2. The spiral spring G holds
the crank in position when adjusted. When closed up the short knife blade D forms
one continuous length of knife blade with the main portion B B.
When opened out the short knife blade D allows the passage for trimming of a
bar of type such as H J, upon one end of which a projecting two-line capital is
formed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In the knife block and knife of a "Linotype" or like machine, a gap or
recess formed for the purpose of allowing the passage when being trimmed of
bars of type which have a projecting or two-line capital such as is represented at H
in Figure 3.
2. In a "Linotype" or machine of a similar class, a knife of which a portion is
made movable to allow the passage of a bar of type, when being trimmed or
trued up, at one end of which bar a two-line capital projects, as shown at H in
Figure 3, and in the gap or recess thus formed a short knife blade is pivotted which
is adapted to be adjusted or removed as described and represented.
3. The construction, operation and general arrangement of the knife of a
linotype machine to which is jointed another and shorter bladed knife, with the
shaft and crank handle, all as and for the purposes described.
4. The pivotted knite and crank handle for operating the same in a linotype or
like machine, for the purpose of trimming or truing up the bars of type either
with or without projecting or two-line capitals.
