PROVISIONAL SPECIFICATION.
An Improved Type Nicking Machine.
I, JOHN WILLIAM MACKENZIE of "Northfield" Oxford Road, Upper
Teddington, in the County of Middlesex Engineer do hereby declare the nature of
this invention to be as follows:-
This invention for an improved type-nicking machine is more especially applicable
for the preparation of type as used in connection with certain automatic type
distributing and composing machines in which each dissimilar type has its own
peculiar nicked conformation corresponding to the orifice of a race over which the
types to be distributed are traversed, so that, as the lowest type of each line in the
distributing wagon passes over its corresponding race orifice it falls through and is
conducted into a groove or conduit from which it is removed as required by an
ejecting device forming a part of the composing mechanism of the machine, and has
for its object to provide a machine which shall effect the nicking of type with great
accuracy and speed; which shall be easily adjusted to cut any combination of nicks,
and which may be manipulated with great ease and facility by any unskilled
operator.
In a type-nicking machine constructed according to this invention a cutter
mandril mounted in adjustable bearings in a frame has a spindle or extension at one
end on which circular disc-cutters for forming the nicks are threaded, their positions
and distances apart being determined by suitable separating washers secured by a
nut, while the positions of the cutters are further adjusted by sliding the mandril
longitudinally by means of the back bearing bush which is adjusted and secured by
suitable locking nuts.
Beneath the rotary cutters is a vertical pillar sliding in the frame of the machine
and surmounted by a horizontal table in which a carrier for holding the type while
being nicked slides.
The type carrier comprises a long sliding bar having a central longitudinal groove
or recess on its upper face extending through its whole length to receive the type
on edge, and provided with a suitable stop and screw clamp at either end for firmly
securing the type while being nicked, while hinged to the back end of its under side
is a rack gearing with a worm secured. to a spindle working in the pillar table and
driven by suitable gearing from the cutter mandril, the front end of the said
rack being pressed downwards by a spring to prevent it jamming when falling
into gear with its driving worm.
The carrier is passed through the feed table from end to end so that several
such carriers may be employed and filled, fed under the cutters, and emptied in
rotation.
The depth of the nicks in the type is adjusted and varied by raising or
lowering the sliding table pillar by means of a screw or other suitable means.

An Improved Type Nicking Machine.
I, JOHN WILLIAM MACKENZIE of "Northfield," Oxford Road, Upper
Teddington, in the County of Middlesex, 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 :—
This invention for an improved type-nicking machine is more especially
applicable for the preparation of type as used in connection with certain auto-
matic type distributing and composing machines, in which each dissimilar type
has its own peculiar nicked conformation, corresponding to the orifice of a race
over which the types to be distributed are traversed, so that, as the lowermost
type of each line in the distributing wagon passes over its corresponding race
orifice, it falls through and is conducted into a groove or conduit from which it
is removed as required by an ejecting device forming a part of the composing
mechanism of the machine, and has for its object to provide a machine which
shall effect the nicking of the type with great accuracy and speed, which shall
be easily adjusted to cut any combination of nicks, and which may be manipu-
lated with great ease and facility by any unskilled operator.
In the accompanying two sheets of illustrative drawings-
Fig. 1 represents a type nicking machine partly in side elevation and partly
in vertical section,
Fig. 2 is a horizontal section,
Fig. 3 is a transverse section through the type carrier and slide table, and
Fig. 4 is a plan of the carrier slide table constructed according to this invention.
In a type nicking machine constructed according to this invention, a cutter
mandril a mounted in bearing bushes b, c in a frame d has a spindle or extension
on which circular disc cutters f of suitable thickness for forming the required
nicks in the type are threaded, their relative positions and distances apart being
determined by adjusting and separating gauge washers g firmly secured together
by a nut h, while their positions are further adjusted by sliding the mandril a
longitudinally. For this latter purpose the back bearing bush c is screw-threaded
at each end and provided with the locking nuts i by which it can be slidden in
the frame and secured in the required position as will be clearly understood.
Friction washers are provided backed by the collar washers m, the whole being
finally secured by the locking nuts n. The bushes b, c are prevented from
turning in their bearings by the feather keys o, p. The mandril a is driven by
a belt through suitable fast and loose pulleys q provided with strap fork tackle
as clearly shown.
Beneath the rotary cutters f is a vertical pillars sliding in the main frame of
the machine, and capable of vertical adjustment by means of the screw t with
micrometer gauge disc v. The said pillars is surmounted by a horizontal
table w in which a carrier for holding the type while being nicked slides.
The type carrier comprises a long sliding bar or case a, having a central
longitudinal channel or recess y on its upper face, extending through its whole
length to receive the type on edge, and provided at one end with a stop having
a steel edge a a for pressing against the type, while the other end is provided
with a three-armed clamp a b and clamping nut ac for firmly securing the type
in the carrier while being nicked.
Hinged to the underside of the carrier at a d is a toothed rack ae gearing
with a worm af mounted on the spindle a g working in bearings a h in the
pillars and table w, and driven from the mandril a through suitable belt
pulleys a i, al and toothed gearing a m, a n, a o, a p as clearly shown, the spindle a q

page_text: sliding freely through the bevel wheel an and being provided with a feather-
way ar to permit of its accomodation to the height of the table w. The front
end of the rack ae rests normally on a stop a s ugainst which it is pressed by the
spring at, but is free to be raised to a limited extent so as to prevent it from
jamming when falling into gear with its driving worm a f.
RC
The type carrier with its column of type is passed through the table w from
end to end, so that several such carriers may be employed, and filled, traversed
under the cutters, and emptied in rotation.
The depth of the nicks in the type is regulated by raising or lowering the
sliding table pillar by means of the micrometer screw.
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 a type nicking machine, the employment of cutter discs threaded on a
mandril and separated by gauge washers, the said mandril being adjusted longi-
tudinally by means of a screw-threaded bush sliding in the frame and secured
in any desired position by means of lock nuts substantially as described.
2. In a type nicking machine the construction of the sliding type carrier with
a channel or recess to receive the type, and with a hinged and toothed rack
gearing with a driving worm substantially as described and for the purpose set
forth.
3. A type nicking machine arranged, constructed and operating, substantially
as described with reference to the drawings.
