Improvements in Type Casting and Dressing Machines.
I, BENJAMIN JOSEPH BARNARD MILLS, of 23 Southampton Buildings, in the
County of Middlesex, Patent Agent, do hereby declare the nature of this inven-
tion, a communication to me from James Gabriel Pavyer, of the City of St. Louis,
in the State of Missouri, one of the United States of North America, Machinist,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had to the accom-
panying drawings forming part of this Specification :-
This is, in some respects, an improvement on Letters Patent of the United
States of America, dated October 15, 1889, numbered 413,087. The features of
novelty will be set forth in the claims.

1 is part of the main frame of the machine, 2 is an oscillating frame or carriage
to which the lower member 3 of the mould is fixed, and to which the upper

page_text: member 4 of the mould is connected by a hinge 5. The types 6 may be dis-
charged from the mould by "pushers," as described in the Specification of the
aforesaid Patent. My present improvement does not apply to the means for
discharging the type from the mould, but for actuating and operating on the type
after it has left the mould.
The type is left by the pushers upon a plate 7 having longitudinal guide rib 8
that enters the transverse nicks 9 cast in the sides of the type. 10 is a bar sliding
in guides upon the fixed frame, and having a vertical lug 11 that works end wise
on a fixed rod 12. 13 is a spiral spring surrounding the rod and bearing against
the lug 11. The spring 13 pushes the sliding bar 10 to the right. 14 is an arm
hinged at 15 to the sliding bar or slide 10.
16 is a finger adjustably attached to the arm 14 by a screw 17 which passes
through a slot 18 of the finger and screws into the arm 14. Ribs 19 upon the arm
rest in grooves of the finger and prevent the finger turning on the bolt while
allowing its adjustment lengthwise of the slot, see Figures XV, XVI, XVII
and XVIII. The finger 16 has at the end, a plate or flat part 20, which is adapted,
in the lower or active position of the finger, to lie upon, or almost touch, the
rib 8 on the plate 7, and whose working edge is parallel to the type, so that it is
adapted, as the plate moves to the left, to bear against the rear edge of the type 6
and force the type along the plate 7. The slide 10, to which the finger is hinged,
has at the under side a stud carrying an anti-friction wheel 21, against which acts
a cam 22 upon the cam shaft 23. The cam 22 acts to move the slide 10 to the
left, and the slide is moved to the right by the spring 13 as soon as the wheel 21
is relieved from the pressure of the cam. It is necessary that the finger 16 should
be raised as the mould is moved toward it, so as to be lifted above the plate 7
as the mould passes from the position seen in Figure I to the position seen in
Figure II. This lifting is done by an incline 24 projecting forwardly from the
mould frame 2, and carried by the forward movement of this frame beneath the
arm 14. The incline acts directly on a plate 25 attached to the arm by a
screw 26. The incline has a notch or recess 27, into which drops the lower edge
of the block 25 when the mould frame reaches its forward position, and this
allows the plate 20 to drop down behind the type 6, which has just been pushed
from the mould; at this time the cam 22 acts on the anti-friction roller 21 of the
slide 10 and the type is pushed to the left, pushing before it the whole line of
types previously cast and remaining on the plate 7, and the stick to be hereinafter
described. It will be understood that as the mould frame moves forward, the
upper member 4 of the mould is lifted, giving way for the discharge of the type
and allowing the plate 7 to pass beneath the plate 20. 28 is an arm forming a
front brace for the hinged arm 14 to resist the horizontal pressure of the incline 24
upon the arm and relieve the hinges 15 from strain. The type is pushed by the
plate 20 beneath a plate 29 held down by a screw or screws 30, so as to hold the
type flat down on the plate 7, while allowing its free movement to the left.
"
While the type is beneath, and being held down by, the plate 29, the "jet
or sprue 31 is broken off by the jet breaker 32, which is attached to the free end
of the upper member 4 of the mould, so that the jet is broken off as the mould
closes for the casting of the next type. On leaving the plate 29, the type passes
beneath the first of two rollers 33 having bearing in a housing 34. The housing
has upon its sides, apertures for the entrance of the grooving cutters 35, by which
the lower ends of the types and quads and the upper ends of the quads may be
grooved. If any dressing is needed to reduce the types to a uniform thickness or
width, it is done by an oblique cutter 36 held by a screw 37. 34*, 34, are screws
held in a suitable bracket, for engaging and holding the housing 34 and an
adjunctive part thereof carrying the cutter 36.
The plate 7 ends in a flexible plate or lip 38 coming to a knife edge, and over
which the types pass to a stick, which will be now described. The stick is com-
posed of a lower member 39 and an upper member 40, and is adapted to hold a
large number of types 6, lying side by side and transverse to the stick. The

page_text: lower member has a channel made from end to end, to receive a rib 41 that is
inserted in the channel and locked in the channel by a key strip or strips 42.
This occupies the nicks in the sides of the types and keeps them from transverse
displacement as they travel along the stick. The purpose of making the rib
removable is to allow its adjustment to types having the nicks in different
positions. The member 39 of the stick has a standing flange 43 against which
rests the side of the upper member of the stick. The upper member has a
tongue 44 whose end rests against the oblique cutter 36 so as to form a top guide
for the types. The end of the lower member is inserted between the flexible
plate 38 and the supporting plate 45, which is fixed to the plate 7. The upper
member 40 is secured to the lower member 39 by any suitable clamp or clamps.
The outer end of the stick is supported upon a rocking standard 50 having a
pivotal support 51 in line with the axis of oscillation of the mould frame 2, s0
that the stick may have free movement with the mould frame. 52 is a counter-
balance weight tending to keep the standard 50 upright. 46 is a screw working
in an arm 47, and whose end is made conical or cylindrical to fit a conical or
cylindrical recess 48 in the upper member of the stick. 49 is a screw having a
conical or cylindrical point and working in the bearing plate 45. The point of the
screw 49 rests in a conical or cylindrical recess in the under side of the lower
member of the stick.
The operation of the machine, as far as relates to the novel features, is as
follows: As the mould frame swings forward, the upper member 4 of the mould
is thrown up, and the type pushed out ready to be acted on by the plate 20. At
the same time the arm 14 is thrown up by the incline 24, lifting the plate 20
above the plate 7. As the mould frame reaches its forward position, the edge of
the plate 25 falls into the recess 27 and the plate 20 descends into position to act
on the type. The cam 22 acts on the slide 10 and moves the plate 20 and the
whole line of types to the left, the types being grooved by the cutter or cutters 35
and dressed by the cutter 36 where required. As the cam 22 leaves the anti-
friction wheel 21, the mould frame having moved backward somewhat, the side
of the inclined plate impinges against the rear edge of the plate 25 and slips
along it, until the movement of the mould frame carries the plate past the end
of the arm 14, when the spring 13 throws the arm to the right, into normal
position, as shown in Figures XVI and XVII. As the mould frame 2 rocks
forward and backward, the type stick and its supporting standard 50 move with
it. When the stick is full of types, it may be removed by simply loosening the
screws 46 and 49 and slipping the rear end of the stick from its bearings.
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 casting and dressing machine, the four motion feed, consisting of
an arm 14 having pusher 20 and hinged upon a slide 10 having a cam stud, an
actuating cam 22 and its shaft, spring 13, and a swinging mould frame having a
notched incline 24 adapted to lift the arm 14 on the forward movement of the
mould frame, substantially as set forth.
2. The combination in a type casting machine, of the moveable upper member 4
of the mould, a jet breaker 32 secured thereto, and the type holding plate 29
arranged adjacently to, and below, the jet breaker, substantially as set forth.
3. The combination in a type dresser, of an unyielding roller 33 arranged in
the path of the movement of the type and adapted to bear on the upper side of
the type, a plate 7 beneath the roller having a rib or bead 8 to fit the side nick
of the type, and the grooving cutter 35 arranged to act upon the lower ends of
the types and quads and upon the upper ends of the quads, substantially as and for
the purpose set forth.
4. The combination in a type casting and dressing machine, of a swinging mould
frame and a type stick, as 39 40, supported at one end upon a standard having a
