TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE:
HASELTINE, of the "International Patent Office," Southampton Build-
ings, London, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
MACHINERY FOR MANUFACTURING TYPE," and have petitioned Her Majesty to
grant unto me, my executors, administrators, and assigns, Her Royal
Letters Patent for the same, and have made solemn Declaration that it

page_text: has been communicated to me from abroad by William Wallace Dunn,
of San Francisco, California, United States of America, Mechanic.
NOW KNOW YE, that I, the said George Haseltine, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement, reference being had to the accompanying Drawing forming
a part of this Specification:-
My Invention relates to certain additions to and improvements in
machines for casting and founding type, by the employment of which
that part of the labor that has heretofore been performed by hand, such
as breaking off the superfluous metal, rubbing, dressing, and planing,
is accomplished by machinery, in the operation of which type can be
produced with much greater facility and more rapidly than by the
ordinary machines now in use or hitherto employed. The said Invention
consists in certain details of construction which will herein-after more
fully annear.
Figure 1 is a perspective view of a machine embodying my Invention.
Figures 2, 3, 4, 5, 6, 7, 8, 9, and 10 shew detached portions of the
same.
Like letters, refer to the same parts in each of the Figures.
The melting pot a is heated by a furnace, not shewn in the Drawing,
and the cavity is kept continually supplied with molten metal. The
plunger c has a vertical reciprocating motion imparted to it by suitable
machinery, not shewn. This plunger is shown in its highest position in
Figure 2, in which position the cylinder or well d will fill with metal
through the passage e.
The sectional area of the plunger is such, and its length of stroke
so adjusted, that in descending it will displace just enough metal to
form one type, and force it out through the passage fup through the
passage g, raising the cylindrical valve and discharging through the
nipple to the carrier or spider; and the mould. When the plunger c
begins its upward stroke the valve h will be immediately forced down-
ward by the spring o closing the passage to the nipple. Increasing the
length of stroke of the plunger will compensate for leakage around or
imperfect filling of the plunger or valve.

page_text: To prevent the excessive heating of the mould a screen k is provided,
between which and the melting pot an air passage should be made.
The mould or matrix consists of three pieces l, m, n, all or either of
which can be readily removed or exchanged at will in order to mould
different forms of type. The rectangular space p formed by the piece
and m is closed at its outer end by the rocking piece n upon which the
matrix for the letter or character is formed, and a separate rocking
picce n should be provided for each character or letter. The molten
metal flowing from the nipple fills not only the mould but the opening
in passage 78 in the end of the arm of the carrier or spider j and forms
between the spider and the type a gate of metal. As soon as the
casting is thus performed the mould is opened and the type released by
means of the following devices, the motions of which are derived from
the excentric q¹
First. The upper part of the mould is raised out of the way and
returned to its position by means of the hinged plater, to which is
attached the swivel box nut 8, wherein is secured by means of the drop
catch

to give the required motion through the intervening mechanism to the
upper piece of the mould, the cam being hinged at 1 and receiving
its motion from a pin 2 on the extremity of the rock shaft arm 3. The
shaft 4 from which the arm 3 proceeds is connected to the rod q of
excentric q¹ by means of arm 5.
Secondly. The rocking piece n is caused to leave the face of the type
by means of the rock shaft 6 and arms 7 and 8 adjusted by the set
screw 9, and caused to return to the mould by means of the adjustable
lever 10 acting on an arm 11 attached to the spring 12. Both the rock
shaft 6 and lever 10 are operated by the sliding cam plate 13, and the
cam plate 13 is impelled by the rod 14 connected with the adjustable rock
shaft arm 15 of shaft 4. As soon as the type is released from the
mould it is carried over by the spider ; and deposited on the type
landing or cutter plate 16 grasped or held in a proper position by the
foot 17 and forced through between cutter 18 and breaker 30 and cutter
plate 16 by the type slice 19 upon the cutter bed plate 20.
The required reciprocating motion is imparted to the slice by means
of the guide plate 21, connecting rod 22, rock shaft 23, arms 24 and 25,

page_text: connecting rod 26, lever 27, connecting rod 28, and crank 29. The
type landing or cutter plate 16 is rigidly secured to the bed plate 20,
and is provided with a diagonal cutter 31 that planes and trims or
shaves the under side of the type as it passes over them while the
cutter 18 trims the top. Breaker 30 separates the gate from the type,
the gate being still retained in the spider arm is carried around until
the extremity of the arm is opposite to the needle or punch 32 when it
is forced out and the recess or opening in the arm thus cleared is in
readiness to repeat its operation with another type. The spider seen in
the Drawing has 6 arms secured to a flange on the shaft 33, consequently
the shaft 33 is rotated one-sixth of a revolution each time that a type
is cast by means of the ratchet wheel 34, stop wheel 35, stop pawl 36,
and pawl arms and pawls 37 and 38, connecting rod 39, lever 40,
the excentric 41. The rod of the excentric 41 is connected to the
lever 40 by means of a pin secured in a slot 42¹ in the lever. The
slotted connection is for the purpose of regulating the throw of the
lever 40.
The plate or mould seat 42 carrying the matrix and the machinery
connected with the excentric q is hinged, secured, and adjusted by the
screws 43 and set or binding screws 45 to a vertical plate firmly attached
to or forming a part of the moving or sliding bed 44. The sliding
bed 44 is forced toward the melting pot by the cam 45 and roller 63,
and towards the cam 45 by a suitable spring. The said roller and
spring are so constructed and adjusted that when the mould is being
filled the face of the mould will press the arm of the carrier tight
against the nipple and prevent leakage of metal, and after the mould
is filled separate the metal from the end of the nipple by moving both
the carrier and the mould away from the nipple.
For the better adjustment of the motion of the moving bed a set
nut 46 is provided. For the purpose of imparting the required corre-
sponding motion to the spider an endwise motion is given to the shaft
33 by means of the collars 47 and 48, between which works an arm 49
rigidly attached to the moving bed. To the moving bed is also attached
another stout arm 50, at the extremity of which is a set screw 51, that
provides a support for the extremity of the arms of the carrier during
the operation of the punch 32 in driving out the gates. The foot 17.
is operated by means of the cam 52, the lever 53, rod 54, lever 55,
spring 56, and adjusted by means of a set screw projecting through the

page_text: plate 57. The cutter bed plate 20 is secured in an inclined position
to the top of the frame 58. Frame 58 is secured to the principal frame
of the machine by the set screws 59, adjusting screws 60, and slot 62,
in such a manner as to be readily adjusted in regard to height and
according to the thickness of the type.

The swivel box nut & is constructed in the manner shown for the purpose
of obtaining a direct and even pressure for causing the face or parts of
the mould to come squarely together. The cutter 18 is secured to the
holder 64 and is raised or lowered to conform to type of different
thickness, by the sliding of the holders on the pillar or rod 65 adjusted
and secured by the screw 66. The pitch of that part of the screw 66
that works in the top plate of the holder is different from the pitch of
the part working in the pillar or rod 65. The melting pot may be
levelled, tilted, or adjusted by means of the adjusting screws 67 and the
holding down screw 68.
The required horizontal motion is imparted to the punch or needle 32 by
the excentric 69, excentric rod 70, cam 71, pin 72, guide frame 73, sliding
plate 74, and clamp 75. The office of the foot 17 is very important
in holding the type firmly down on the type landing and preventing its
being turned or tilted over by the cutter 18, or being thrown out of
place by the leverage of the gate over the breaker 30. The operation
of the slice in bearing uniformly on the type throughout its length
and forcing the said type laterally through the cutter prevents the
possibility of bending or injuring said type during the trimming,
rubbing, or planing. The time of the movements of the parts of the
type mould is regulated by the relative angular position of the arms
3, 5, and 15, on shaft 4, said angular position being adjusted by means
of the set screw 76.
77 is the driving shaft that communicates motion to all the moving.
parts.
The holes or recesses 78 in the extremities of the arms of the carrier
or spider are taper, having their largest end towards the mould, these
holes are tapered in order to keep the gate from being drawn through
them towards the nipple, and thus breaking the gate off of the type
while the type is still in the mould. The screen k is an important
device for the reason that without it the moulds would become so heated
by the radiation from the melting pot that the metal would not have

page_text: The filling of the mould through one arm, the clamping of a type by
the foot 17, and the driving of the gate out of the hole 78 of the lower
arm being simultaneous operations, it is evident that the number of
arms to the spider may be any multiple of three provided that the
herein-before described machinery for giving motion to the shaft 33 is
proportioned to correspond to the number of the said arms, that is to
say, if only three arms are used the shaft should make one-third of a
revolution for each type that is cast, or if nine arms are used one-ninth
part of a revolution.
Having thus fully described the said Invention as communicated to
me by my foreign correspondent, I wish it understood that I do not
claim, broadly, the employment in type-making machinery of the melting
pot a, nipple i, carrier or spider j, or a hollow flange for forcing out
the metal; nor do I claim any peculiarity in the mould or matrix l, m, n,
hinged plate r, adjustable lever 10, or spring 12, nor hinging, securing,
or adjusting the mould seat 42 to a bed by the screws 43 and 45.
Neither do I claim, broadly, operating the machinery connected with the
casting of type by a revolving shaft, nor the employment of the cam 45
and roller 63, for the purpose of causing the matrix or mould to approach
and recede from the nipple i.
