Improvements in or applicable to Type Casting Machines and
Moulds.
I, OLIVER TITCHENER, of 3, Wilmington Street, Clerkenwell, in the County of
London, Type-founders' Engineer and Machinist, do hereby declare the nature
of this invention to be as follows:-
My invention relates to type casting machines and moulds. In type casting
machines as heretofore constructed the type has generally been delivered in an
unfinished condition, that is to say, it was delivered with what is termed a break
attached thereto which had to be subsequently detached by hand and the type had
then to be set up on setting up sticks and transferred onto a dressing rod
which was placed in a dressing bench in order to have the burr removed and
the groove made in the end by means of a dressing plane.
The object of my invention is to provide simple and inexpensive means for auto-
matically finishing the type before it leaves the type casting machine thereby
dispensing with the necessity of employing persons to perform this operation.
In carrying out my invention instead of allowing the type to fall from the mould
into a shoot which delivers it to a tray as is usually the case I provide a suitable
arrangement of mechanism for pushing the type from the mould into a guide bed
and knocking off the break, a cutter then coming into action and cutting off the
burr and forming the groove in the foot of the type. The type then passes onto
setting up sticks which are advantageously mechanically moved forward as they
become full, thus delivering the type arranged in proper order for packing.

Improvements in or applicable to Type Casting Machines and
Moulds.
I OLIVER TITCHENER, of 3 Wilmington Street, Clerkenwell, in the County of
London, Type-founders' Engineer and Machinist, 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 :-
My invention relates to type casting machines and moulds. In type casting
machines as heretofore constructed the type has generally been delivered in an
unfinished condition, that is to say, it was delivered with what is termed a break
attached thereto which had to be subsequently detached by hand and the type had
then to be set up on setting up sticks and transferred onto a dressing rod which was
placed in a dressing bench in order to have the burr removed and the groove made
in the foot by means of a dressing plane.
The object of my invention is to provide simple and inexpensive means for
automatically finishing the type before it leaves the type casting machine
thereby dispensing with the necessity of employing persons to perform this
operation.
In carrying out my invention instead of allowing the type to fall from the
mould into a shoot which delivers it to a tray as is usually the case 1 provide

page_text: a suitable arrangement of mechanism for pushing the type from the mould into a
guide bed and knocking off the break, a cutter then cutting off the burr and
forming the groove in the foot of the type. The type then passes onto setting up
sticks which are advantageously mechanically moved forward as they become full,
thus delivering the type arranged in proper order for packing.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawings, in which

Figures 7 to 18 are drawn to a larger scale than Figures 1 to 6.
Similar letters in all the figures indicate corresponding parts.
a indicates the bottom section of the mould which fix to the bottom mould
block in the usual manner, the said block being mounted on a dovetail slide
bed c sliding in a bracket or guide a fixed to the table of the machine (not shewn).
The said slide bed has a backward and forward motion imparted to it by means of
a came and a spring i, the said cam being mounted on the main shaft f of the
machine and working against a roller g journalled in a bracket h on the slide bed c
while the spring i is attached to the front of the slide bed and to a bracket j
bolted to the bracket d.
is the upper section of the mould connected to the usual plate p hinged on
centres m, m in the usual manner in a forked bracket n bolted to the bottom mould
block b in order that it may be raised or moved apart from the bottom section a to
allow each type to be removed. The said top section is raised by means of the
usual bar o which is jointed to the plate p and advantageously adjustably connected
by a slotted plate k and nut k³ to au upright arm 7 fixed to a block r guided
vertically on a bar q³, the said block having guiding strips 9, 7.

The block is provided with a pin s sliding in a guide-block t pivotted at u to a
forwardly projecting lever v pivotted at to one of the frames or brackets v
carrying the shaft f, the said lever carrying a roller w against which bears a came
on the main shaft and a spring y for opening and closing the mould.
The pivot u enables the bar o to be detached from the plate p in the usual

The bottom section a of the mould is provided with a sliding plate or pusher
pushing the type out of the mould into the guide-bed hereinafter described, the
hand end of the pusher forming one side of the recess a¹ in which the type is
The pusher is actuated in a backward direction by a cam b! on a cross
ft c¹ rotated in bearings in brackets d'; d' on the frame through the medium
bevel wheels e, e', the said cam bearing against a roller carried by the tail
d of a lever g' fulcrummed at in a bracket i¹ on the frame vs, the upper end of
e lever g¹ being connected by a link j¹ to a sliding block 3 attached to the
sher by a connecting plate j.
The roller f¹ is kept to the face of the cam 61 by the action of a spring 2
tached to the tail of the lever g' and to a bracket or bar s on the frame. The
sher z is driven forward by means of an arm 2 upon the shaft c' which arm
rries a roller 2 which, as the arm revolves, presses against an arm v² on the
ver g'.
k and are passages in the mould through which water from any suitable source
caused to flow for the purpose of keeping the mould cool.
The
m² is the guide-bed which receives the type as they are pushed out of the mould,
nd guides them to the setting-up sticks n', the said guide bed being fixed at one
nd to a table o' which carries the setting-up sticks as hereinafter explained, the
aid table being supported by brackets o from one of the frames v.
other end of the guide bed abuts against the delivery end of the bottom section of
the mould. The said guide bed m¹ is provided with a cover p¹ hinged thereto at q
and secured by means of a plate or catch r pivotted at s¹ to the cover p' and
having notches engaging with notches in brackets t', t¹ secured to the guide bed.
u' is the striker which knocks off the break v¹ from the type w¹, shewn in dotted
lines in Figure 11, directly it has entered the guide bed m³, the said striker being
fixed to the top plate p carrying the upper section of the mould so that it acts as
the said section descends to close the mould as will be understood by reference to
Figure 12.
The nick in the type w¹ is formed by a rib y' secured by preference to the
upper section of the mould and a similar rib is provided on the underside of
the cover pl of the guide bed which, by fitting the nick in the type serves to assist
in guiding the latter along the bed and keep them square with the same when being
acted upon by the cutter hereinafter described. It will be obvious that the said
ribs can if desired be arranged on the bottom section a of the mould and guide bed.
a² is the cutter for cutting off the burr which is left on the foot of the type after
the break v' has been knocked off and for simultaneously forming the groove in the
said foot. This cutter is adjustably fixed to a bracket 62 secured to the table o¹
and projects inside the guide bed m¹ through a longitudinal opening m³ between the
guide bed and its cover as clearly shewn in Figure 15 so that it acts on the type
as they pass in succession along the guide bed.
The setting-up sticks n' which receive the type as they pass out of the end of
5 the guide bed m³ are moved forward by the attendant as they become full by means
of an endless chain moving over a chain wheel d² and rollers e², e² beneath the
table o¹, and provided with pins f2 which project up through a slot g' in the table
and enter holes in the undersides of the sticks.n', which are further provided with
ribs ², sliding in guide grooves in the table. The chain wheel dis rotated to
50 an extent just sufficient to move a full stick away and an empty one into its place
by means of a lever handle operated by the attendant and carrying a spring
pawl engaging with a ratchet wheel on the chain wheel shaft m², the distance
between the teeth of the said ratchet wheel and the extent of movement of the
lever handle being regulated to this end; n² is a stop pin on a bracket o² for
55 limiting the said extent of movement of the lever handle.
The mechanism for delivering the matrix a*, and keeping it firmly pressed to
the face of the mould is similar to those described in the Specifications of my

page_text: +
former British Letters Patent No. 5795 of 1884 and No. 12621 of 1885 and the
remaining parts of the machine are of ordinary construction and therefore do not
not require to be described.
The operation of the machine is as follows:-
Assume the mould to be closed and pressed firmly against the nipple plate p³ of
the melting pot q² for the type metal by the cam e, and the pusher z in its rearward
position as shewn in Figures 2 and 3. If the machine be set in motion by the
driving pulley w² actuated by a cord from a suitable motor or by a handle (not
shewn) the molten type metal is forced into the mould by the usual mechanism
(also not shewn). The came then allows the mould to be drawn forward by the
spring to disengage the break of the type from the nipple plate p and bring the
mould in line with the guide bed. The cam a then allows the top section of
the mould to be raised or open as shewn by the dotted lines in Figure 7 by the
spring y, Figure 1, the type being then pushed out into the guide bed m¹ by the
pusher z (actuated by its cam 6) into the position shewn by the dotted lines,
Figure 7.
The cam r, through the medium of the arm o, and intermediate parts, then
closes the mould whereby the break v¹ of the type is knocked off by the striker n¹
and the mould is moved back by the cam é into position for casting another type
which is subsequently pushed into the guide bed in the manner hereinbefore
described and so on, each type as it is ejected from the mould pushing forward the
type in front of it. The type in their movement along the guide bed towards the
setting-up sticks pass the cutter a² in succession, whereby the burr is cut off and
the groove formed in the foot of the said type, which then pass onto the setting-up.
stick n' in line with the guide bed. Each setting-up stick as it becomes full is
moved forward and another stick brought into position by the attendant operating
the lever handle as hereinbefore described.
When requiring to form an additional nick in the type 1 advantageously employ
the device shewn in Figures 17 and 18 which consists of a cutter projecting
through an opening in the cover pl of the guide bed and carried on a bracket y*
fixed on the said cover. The said cutter is attached to a slide 22 adjustable
vertically by a screw in a slide 2 the said latter slide being adjustable horizontally
in the bracket y2 by means of a 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. A type casting machine in which the type as it is cast is pushed from the
mould into a guide bed, then acted upon by a striker which knocks off the break
and by a cutter which cuts off the burr and forms the groove in the foot of the
type, the finished type then passing onto setting-up sticks in proper order for
packing, substantially as hereinbefore described.
