page_text: I, JOHN ANDREW TAYLOR of N° 91 Alderminster Road, Bermondsey in the
County of Surrey, Printer do hereby declare the nature of this invention to be
as follows:-
"
My invention relates to the manufacture of compound types, that is to say types
of several letters combined together so as to form words of frequent occurrence
such as "and," "the," or common prefixes or suffixes such as pro" "ing" &c, such
compound types being useful for facilitating composition of formes. In order to
illustrate my invention I will assume that I have to provide two compound types,
as for example to print the words "and" and "the." I provide a mould consisting
of two pieces, one of which slides longitudinally into the other, each piece being
partitioned in such a manner that when the one is slid into the other there is a
rectangular spare in the middle with a channel opening from it to one end of the
mould. There are also two sets of notches cut in the partition at one side of this
space, into which are inserted the two sets of ordinary types that are to be combined.
Thus in one of the notches are placed types and and in the other are placed th
and e, which are held firmly in position by pressing the one part of the mould
inwards. If there were only two types in each case, that part would be pressed
farther inwards, if there were more than three types, it would not be pressed so far,
the sliding of the one part of the mould relatively to the other in each case allowing
for different widths occupied by the several types. The character ends of the types
which are inwards rest on fillets projecting a little from the side of the farther
partition of the one part of the mould beyond the middle space, across which the
bodies of the types extend; and when the other part of the mould is slid into
position similar fillets on it come up to and bear against the types. Two slips
equivalent in thickness to the prominence of the fillets are then inserted from the
end of the mould, and thus the middle space of the mould is closed except in
respect of the channel opening from it to the end of the mould. By this channel
fused type metal or similar alloy is injected into the space, and this metal encloses
the bodies of the two sets of types which pass through the space. When the metal
has set the parts of the mould are separated, and then. is withdrawn from it the
rectangular block of metal having enclosed within it the two set of types, the

page_text: character ends of which project from one side of it a distance determined by
the prominence of the fillets above mentioned. On this block of metal is electro-
typed a copper matrix which is afterwards justified and employed to form the
bottom of an ordinary type mould. Thus for casting the compound type "and,"
the matrix is applied to the type mould with one of its two impressions forming
the bottom of the mould. When the type "the" has to be cast, the same matrix
is turned end for end so as to present the other impression to the mould. By thus
arranging two sets of types accurately in the first block mould and producing a
duplicate matrix with its two impressions justified relatively to one another, I am
enabled to dispense with half the number of matrices that would otherwise be
required, and I thus greatly reduce the cost of manufacturing and storing the
multitude of matrices required for founts of compound types.

I, JOHN ANDREW TAYLOR, of N° 91 Alderminster Road, Bermondsey in the.
County of Surrey, Printer, 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 the manufacture of compound types that is to say types
of several letters combined together so as to form words of frequent occurrence
such as «<
and," "the," or common prefixes or suffixes such as "pro," "ing" &c,
such compound types being useful for facilitating composition of formes. In order
to illustrate my invention I will assume that I have to provide two compound
types, as for example to print the words "and and "the." I provide a mould
consisting of two pieces, one of which slides longitudinally into the other, each
piece being partitioned in such a manner that when the one is slid into the other
there is a rectangular space in the middle with a channel opening from it to one
end of the mould. There are also two sets of notches cut in the partition at one..
side of this space, into which are inserted the two sets of ordinary types that are
to be combined. Thus in one of the notches are placed types and and in the
other are placed th and e, which are held firmly in position by pressing the one
part of the mould inwards. If there were only two types in each case, that part
would be pressed farther inwards, if there were more than three types, it would not
be pressed so far, the sliding of the one part of the mould relatively to the other
in each case allowing for different widths occupied by the several types. The
character ends of the types which are inwards rest on fillets projecting a little from
the side of the farther partition of the one part of the mould beyond the middle
space, across which the bodies of the types extend, and when the other part of the
mould is slid into position, similar fillets on it come up to and bear against the
types. Two slips equivalent in thickness to the prominence of the fillets are then
inserted from the end of the mould and thus the middle space of the mould is
closed except in respect of the channel opening from it to the end of the mould. By
this channel fused type metal or similar alloy is injected into the space, and this metal
encloses the bodies of the two sets of types which pass through the space. When
the metal has set, the parts of the mould are separated, and then is withdrawn
from it the rectangular block of metal having enclosed within it the two sets of
types, the character ends of which project from one side of it a distance determined
by the prominence of the fillets above mentioned. On this block of metal is electro-
typed a copper matrix which is afterwards justified and employed to form the
bottom of an ordinary type mould. Thus for casting the compound type "and,"
the matrix is applied to the type mould with one of its two impressions forming
the bottom of the mould. When the type "the" has to be cast, the same matrix
is turned end for end so as to present the other impression to the mould. By thus
arranging two sets of types accurately in the first block mould and producing a
duplicate matrix with its two impressions justified relatively to one another, I am
enabled to dispense with half the number of matrices that would otherwise be
required, and I thus greatly reduce the cost of manufacturing and storing the
multitude of matrices required for founts of compound types.

page_text: Fig. 1 of the accompanying drawings shews a transverse section of a mould
according to my invention, Fig. 2 is a longitudinal section and Fig. 3 an end view.
Fig. 4 is a perspective view of a double matrix which it is the purpose of my
invention to produce. The two, three or more types T that are to be combined to
form one compound type are placed in one part of the mould and the other types T¹
that are to form another compound type are also placed in it, the character ends of
the types in both cases resting on fillets F. F. The two parts M M¹ of the mould
are then slid together, and slips S S¹ are inserted from the end, these slips passing
over the character ends of the types and close up to the end fillets against which
the types are pressed. There is thus left in the middle of the mould a rectangular
space B crossed by the two sets of types. By a git G molten metal is run in to
fill this space producing a rectangular block B in which the two sets of types are
enclosed, presenting their characters a little beyond one. face of the block. On
this block is electrotyped the copper matrix shewn in Fig. 4 which, after being
properly justified, can be used in ordinary type moulds for casting the one of the
compound types, and by inverting it can be used for casting the other.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that
what I claim is :-
1. For manufacturing compound types the preparation, substantially as herein
described, of a double matrix capable of being used in one position for casting one
compound type and in an inverted position for casting another.
2. For casting a block as basis on which a double matrix is electrotyped, the
construction of mould substantially as herein described and illustrated.
