page_text: I, FREDERICK WICKS, of Halfway Lodge, Esher, in the County of Surrey, News-
paper Proprietor, 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:—
In my Specification No. 4986, dated the 9th day of March 1894, I have described
type founding apparatus comprising a rotating disc having radial grooves in
which matrices in the form of plungers slide to and fro, these grooves at one
part of the revolution when the plungers are retracted presenting themselves
successively to a nozzle whence they receive jets of molten metal forming types
which at other parts of the revolution are extruded on to a carrying chain. My
invention relates to improvements in apparatus of this kind but in order that these
improvements may be clearly understood, I shall describe, referring to the accom-
panying drawings, the whole apparatus, the improvements forming the subject of
iny present invention being distinguished by the claims at the end of the
Specification.

Figure 9 is a longitudinal section of the compressible space type.
The disc A is mounted on a stationary vertical axis A¹ and is caused to revolve
by a pinion in any convenient position gearing with teeth A³ on the flange at
the base. In the disc are cavities A³ through which, for the purpose of cooling,
water circulates, ascending and descending by passages A4 A5 bored up the axis
and the boss respectively. The upper face of the disc has numerous radial grooves
in each of which is fitted to slide a plunger B. The outer end of this plunger has
a character engraved or impressed upon it so that it forms the matrix for a type.
The inner end B₁ of the plunger is made of considerable height and is held by
small screws between shoulders of a guide piece B2 having at its inner end an
adjusting screw B³. Above the disc A there is fixed on the upper part of the

page_text: axis A¹ a bracket piece E having a dovetail groove in which slides an arm C. On
the axis A is also fixed a flange E³ carrying a cam E' and other cams D2, D* for
determining the movements of the plungers B. The arm C has a part C₁ turned
downwards and forming a shield C which by means of an adjustable spring E
is made to bear closely against the edge of the disc A where it is grooved and
there it has a projecting rib with a small, bole through which jets of molten metal
are discharged from the nozzle C3 into the grooves of the disc A as they successively
pass the hole.
The surplus metal runs down into the pot C4 by a conduit C5 which
dips into the fluid metal, so that the metal as it descends is not oxidised by ex-
posure to the air. The nozzle 03 is supplied with molten metal from, the pot C+
in the usual way by a suitable pump which forms no part of my invention. The
small hole through which the metal is sent as a jet is situated in the rib projecting
from the shield C this rib being of approximately semicircular section and the
edge of the disc A has a groove all round the periphery suited to this projecting
rib which forms the nick in the foot of the type. Spaces C7 for circulation of
cooling water are provided in C these spaces being so formed that the water is as
near as possible to the hole through which the metal is discharged. Above the
disc A is a cover piece which is cooled by circulation of water and which bears
against the face of the Shield C2 and is kept down by screws C6 that can be
accurately adjusted to press it down upon the face of A at the place where the
metal is injected into the moulds formed in those parts of the grooves of A which
are left vacant by the withdrawal of the matrix plungers.
The cover piece D has on its underside a projecting rib which forms the nick
in the side of the type and the disc A has a corresponding circular groove on its
face. There may be several of such ribs and grooves when the types are to have
several nicks. A ring D¹ rotating with A has on its underside grooves corres-
ponding to those in A which serve as guides to the rear parts of the matrix
plungers. A cam D2 which can be accurately adjusted in postion by a screw D³
determines the position of the matrix plungers at the time when the mould is
receiving metal each plunger being individually adjusted to extend more or less
forwards by its screw 133. The inner face of a cam D retracts the plungers as
they are approaching the nozzle, this cam being shaped so as to retract them a
little farther than required so that the cam D afterwards acting on them has
to push them a little outwards. By means of the cam Et the matric plungers are
pushed forward so as to extrude the types from the grooves. This cam is grooved
so that it does not act on the small adjusting screws B³, but on the ends of the
pieces B attached to the plungers. In like manner the cam 14 acts on the front
of those pieces. The ring D₁ is supported by studs at intervals projecting up from
the disc A and the cams D2 and I are supported independently of A from the
piece E.
As shewn in Figure 8 a special disc and set of matrix plungers and a special
shield are employed to cast space types S of the shape shewn in Figure 9 so that
they can be compressed, the line of type in which they occur being composed a
little longer than required and then justified by compressing it. The shield C
has a projecting rib C with a central hole through which the molten metal is
injected, and the matrix plunger 13 terminates in a nose of similar section B* the
space type being formed by the metal between and on each side of the rib Cs and
the nose B. The disc A has in this case a groove all round its edge corresponding
to the rib C. Obviously by altering the forms of the parts Cs and B' the form of
the space may be more or less varied.
The types are extruded from the moulds by the advance of the matrix plungers
caused by the cam E', and as they are extruded they are received in channels in
the upper faces of links F of a chain. These links are connected together by pins which
allow it to bend freely in one plane and which are somewhat loose so as to give
the chain a little flexibility transversely.
Each link of the chain is made with two vertical grooves on each side of which
grooves is fitted to slide a piece f. When the chain is on a level bed the upper

page_text: parts. f of the two pieces f project above the upper face of the link forming
between them the channel in which a type is received; but when these pieces are
depressed by their shoulders f passing under an inclined rib, while their lower
ends f descend an incline into a groove, then their heads f¹ are lowered down
to the level of the upper surface of the link leaving the type free to be moved
onwards.
The chain F formed of a number of these links passes for some distance along
with the periphery of A which has teeth a engaging in the spaces between the links
of the chain, it passes down a slight incline round a guide roller G³ again up
a slight incline and around a horizontal roller G.
As the chain travels along with the periphery of the disc A, each successive
groove of the disc has presented to it the channel formed between the two pieces f¹
of each successive link to receive a type from each successive groove of the disc,
and when a type is quite extruded it is still carried on some distance by the link
which has received it.
In this part of its course the chain travels over a level table F¹ till it reaches a
point where it travels down a slight incline F2 so as to pass under a table T on
which the types are collected. At the point where the incline F2 begins, there
begin also but with a rapid slope two grooves F3 which receive the lower ends f
of the sliding pieces f In the same vertical line with the rapid slope of the
grooves F3 there are rapid downward slopes of two ribs T projecting down from
the table T so as to bear upon the shoulders f2 of the sliding pieces fr The effect
of the sudden slope of these ribs is to depress the pieces f as they pass under them
leaving the type free on the upper surface of the link and resting on the projecting
ends of the ribs T¹. The chain in returning from the pulley G₁ to G meets with
a corresponding upward incline and corresponding upward slopes terminating
its grooves F3 so that the chain is raised again to its proper level in passing round
the pulley G, and the pieces f are again raised so as to form the type channel.
At the point where a type is about to be quite clear from the channel of a link,
the front side of which channel first descends a revolving approximately semi-
circular helical blade H passing behind the type as the rear side of the channel
is descending urges the type forwards along the table T and under a covering
piece H causing it to push onwards the row of types already collected on the
table T. The helical blade H¹ is fixed on a horizontal spindle H4 driven by bevil
gear from a vertical spindle H5 worked by suitable gear from the teeth A³ on the
lower flange of the disc A.
Although in what precedes I have described the construction and operation of the
whole type founding apparatus, it is to be understood that no general claim is
made to apparatus of this kind but only to the improvements in details as set forth
in the following claiming clauses.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is: :-
1. In combination with each matrix plunger a guide piece fixed on its rear and
provided with an adjusting screw, substantially as and for the purpose set forth.
2. In combination with the shield guides for its sliding limb fixed on the
