Improvements in or relating to Type-writing Machines.
I, HIRAM JOSEPH HALLE, of 186, Kensington Street, City of Cleveland, in the
County of Cuyahoga, and State of Ohio, United States of America, Manufacturer,
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 typewriting machines, and particularly to typewriting
machine supports, and has for its object, primarily, to provide a construction of
rails or tracks for supporting book typewriting machines whereby during the
adjustment of a book, or other object which is to receive the impression of
the printing characters, the machine may be so positioned as not to interfere with the
turning of the book-leaves, without requiring the removal of the machine from the
rails or tracks to provide the machine-guiding and supporting members, respectively
positioned outside of or beyond and spanning the printing field or area, or that
space within which the printing is accomplished; and also to provide rails of
sectional construction, having stationary or permanent and movable members, of
which the latter. span the printing field or area, of the type writer, while the former
are located outside of or beyond the printing field or area.
Further objects and advantages of this invention will appear in the following
description, and the novel features will be particularly pointed out in the appended
claims.

The base, 1, (Figures 1, 2, 3, 9) which may be constructed in the form of a
horizontal table top, and may, as illustrated, be provided with suitable supporting-
legs, carries front and rear, preferably adjustable, strips, 2, forming platen-rests,
the interval between the strips or platen-rests being such as to receive a book
positioned upon the base. When adjustable the platen-rests may be provided with
operating mechanism consisting of segment or mutilated gears, 3, connected in
pairs, by spindles, 4, which are arranged longitudinally of the base, racks, 5,
depending from the strips or platen-rests and engaged by the segment or mutilated
gears, and worms, 6, meshing with worm-gears, 7, on said spindles, and carried by
a worm-shaft, 8, provided, beyond the front edge of the base and within reach of
the operator, with an operating crank, 9. The means for vertically adjusting the
platen-rests form no part of my present invention.
The platen-rests, in the construction illustrated (in said Figures 1 to 13) carry
a platen which is of sectional or two-part construction, comprising a main or
operative leaf-member, 10, which spans the printing field or area or the interval
between the rests, and is co-extensive with the printing field of the typewriting
machine which is to be used in connection with the supporting mechanism, or is
co-extensive with one or more leaves of the book located between the strips, 2:
and a platen-extension or stationary leaf or member, 11, which is located beyond
or outside of the printing field or area of the typewriting machine, or outside of
the space between the supporting strips. This platen-extension or normally
stationary leaf or member is adapted to support the typewriting machine when the
latter is not in use, and it may be upheld by the rear supporting-strip, 2, through
the assistance of angle brackets, 12, or the equivalents thereof, when the supporting-
strips are adjustably mounted, whereby the adjustment of the supporting-strips
causes the corresponding adjustment of the platen-extension or stationary leaf or
member. The main or operative platen-leaf or member, which spans the interval
between the supporting-strips, or spans the printing field of the typewriting machine.
is movably mounted with relation to the platen-extension or normally stationary
leaf, and may be hinged upon the supporting-strip, as indicated in the drawings,
Figures 1 and 2, by means of hinge-eyes or clips, 13, and 14, fitted upon a hinge-
rod or pin, 15, which is secured to said strip, the front edge of the movable platen-
leaf or member being adapted, in normal position, to rest upon the front supporting-

page_text: strip, as indicated. The main or movable platen-leaf or member is designed to
support the impression-sheet, or the leaf of a book which is to receive the impression,
whereby in writing the printing members of the machine strike downwardly toward
the platen as a backing.
The platen is provided with tracks to guide a typewriting machine in traversing
its surface, and preferably the book-leaf or sheet which is receiving the impression
is held in a flat condition upon the surface of the platen by means of rails, 17,
constructed to carry the frame of the typewriting machine, and also of sectional
construction, or consisting of members, of which the main or movable member is
supported by the main or movable platen-member, 10, and the extension or stationary
rail-member 18, is supported by the extension or stationary leaf or platen-member 11.
Also, these rail-members may be hingedly connected, as shown in Figures 4--7
and 12-18, the length of the auxiliary or extension rail-members in either form
being sufficient to support a typewriting machine when the latter is disposed beyond
the printing field of the mechanism, and is at rest. Obviously, the length of the
main rail-members depends upon the width of the printing field, and may be varied
to suit the functions of the machine which is to be used in connection therewith,
Various means may be adapted to maintain the platen-members or leaves in the
desired relative positions, and in the required positions with relation to the strips
or rests. For instance, in Figures 1 and 2, as above indicated, the platen-members
may be provided, respectively, with eyes, 13 and 14 fitted to slide upon a hinge-1od,
15, the eyes of one member being arranged between those of the other member,
whereby the adjustment of the member, 10, parallel with the hinge-rod causes the
corresponding adjustment of the member, 11, the latter being provided with means,
such as depending, ears, 19, which bear against the rear side of the rear rest, 2,
to maintain the member, 11, in a horizontal position, or in a common plane with
the main member, 10, when the latter is in its operative position. In the con-
struction illustrated, the cars, 19, consist of the downturned portions of the angle-
brackets, 12, herein before mentioned, and in this construction, shown in Figures !
and 2, said brackets may be secured to the under side of the platen-member, 11.
In this particular of the attachment of the brackets to the under side of the platen-
member, 11, the construction illustrated in Figures 1 and 2 differs from that illus-
trated in Figures 9 and 10, wherein the brackets, 12" are secured to the rear side
of the strip 2, and are not adjustable with the platen-members. On the other
hand, in said construction shown in Figures 9 and 10, the platen-members 10"
and 11 are connected by interlocking eyes 13" and 14" and an engaging hinge-
rod 15, the latter being separate from the strip 2ª, and hence providing for the
arrangement of the platen at any desired point, or the entire removal thereof from
the base, as indicated in Figure 11. In this construction shown in Figures 9
and 10, however, I have found it desirable, (to prevent rearward displacement of
the platen) to provide the brackets 12" with upstanding studs or ears, 20, which
engage suitable sockets or openings in the platen-member 11ª.
Again, in Figures 12 and 13 the platen-member, 10b, which is supported by the
front and rear strips, 2b, is supplemented, to form a stationary or temporary sup-
port for the typewriting machine, by a stationary leaf or member, 11, which is
permanently secured to the rear strip or rest, 2b, by brackets, 12b. In this con-
struction, the stationary leaf. or member, 11b, which is arranged in a common
plane with the member, 10b, may be made co-equal in length with said strip, and
hence with the path of the member, 10b which, by means of eyes, 13, is mounted
for adjustment upon a hinge-rod, 15b, carried by said rear strip, 2b.
Moreover, in the construction illustrated in Figures 14 and 15, the base, 1°, is
constructed with the front and rear supporting-strips or rests, 2c, flush therewith
and stationary, and the book is adapted to be supported below the plane thereof by
a vertically adjustable platform, 21, co-extensive with the printing field or area,
and provided with adjusting devices analogous to those herein before described
as designed for securing the adjustment of the supporting-strips or rests, and hence

page_text: requiring no further detailed description. In this form of the apparatus the main
platen-leaves or members, 10°, are hinged to the rear strip or rest, 2, and flush
with the upper surface thereof, and hence with the table-top or base, and the latter
is provided with an extension forming a stationary leaf or member, 11°, which is
adapted to perform the functions of the leaves or members, 11, 11" and 11b, as
hereinbefore described in connection with other forms of my invention, said leaf
'or member, 11, also being flush or in a common plane with the main leaf or
member, 10°.
Also, in Figure 16 I have shown a base 1, front and rear supporting-strips or
rests, 2, and a main platen-leaf or member, 101, which, however, in contradis-
tinction to those forms of my invention which are described in connection with
the foregoing figures, is hinged at its side edge, to fold laterally instead of folding
from the operator, for a reason which will be understood as the nature of my
invention is more fully disclosed. In this form of my invention the leaf or
member, 11, is also permanently secured in the plane of the leaf or member 10ª.
In connection with the construction illustrated in Figures 1 and 2, it will be
seen that I have shown tracks, arranged in parallelism upon both leaves or
members of the platen, and consisting of rails, of which those members which are
arranged upon the main or movable platen-leaf or member, 10, are so disposed as
to allow a book-leaf or other impression-sheet to be arranged thereunder, or between
the same and the upper surface of the platen, to receive the impression of the
printing characters. These rail-members, while arranged in parallelism, in order
to allow the machine traversing the same to be pushed from those upon the main
leaf or member to those upon the other leaf or member, without raising or lower-
ing the machine, or otherwise moving it out of its straight path, need not be in
alinement; and for analogous reasons the rail-members which are arranged upon
the main platen-leaf or member may be movable or adjustable laterally with
relation to each other to vary the interval there between, to suit lines of writing
(at right angles thereto) of different lengths, while those rail-members
be fixed,
are supported by the auxiliary platen-member may
or permanently attached to the said platen-member, or at least may be incapable
of relative adjustment upon said platen-member. In the construction illustrated in
Figures 1 and 2, the main and auxiliary rail-members, 17, and 18, are shown in
parallelism, but out of alinement, the interval between the auxiliary rail-members
being such as to correspond with the widest or most remote setting of the main
rail-members, and hence being designed to support the machine, when pushed
rearwardly thereon, at any relative adjustment of the main rail-members, 17.
This, obviously, avoids the necessity of adjusting the auxiliary rail-members to
suit the adjustment of the main rail-members. The auxiliary rail-members at
their rear ends are provided with stops, 22, to limit the rearward movement of a
machine traversing the same, to prevent displacement, and both the main and
auxiliary rail-members may be provided with depending pins, 23 and 24, to engage
sockets, 25, and 26, depending upon the rail-members. It will be understood,
however, that other means may be employed for arranging the rail-members in the
desired positions upon the platen-members, or, with sufficiently heavy rails, attach-
ing devices may be dispensed with entirely.
which
In the construction illustrated in Figures 9 to 11, a corresponding separate and
non-alined arrangement of rail-members, 17" and 18, is disclosed, the same being
provided with corresponding means of attachment to the platen-members, said
means being such as to provide for the displacement or detachment of the rail-
members, and consisting, essentially, of pins on the rail-members fitted in openings
or sockets, 25 and 26", in the platen-members. The detachable form of platen
illustrated in said Figures 9 to 11 is desirable in that it is adapted to be used in
connection with other than the special form of supporting means or rests disclosed
in these figures, and, in fact, constitutes the simplest form of typewriting machine
support having main and auxiliary members which are arranged respectively within

page_text: and outside of or beyond the printing field or area, to support the typewriting
machine respectively in operation and at rest.
It will be understood from the foregoing description that the forms of rails or
tracks illustrated in Figures 1 and 2, 9 and 10, are adapted to be arranged in
alinement when the space required between the main rail-members is equal to
that which is provided between the auxiliary rail-members.
Therefore, in operation, when it is desired to change the book, by turning one
or more leaves, or otherwise to secure the required surface to receive the impression
of the printing characters, the typewriting machine, which is indicated in dotted
lines in Figure 2, should be shifted, beyond the printing area, to a position upon
the stationary auxiliary members of the rails, where it is supported by the platen-
extension or member. The front ends of the rails, or the movable members thereof,
may then be elevated to adjust the sheet or page upon the main platen-member, 10,
or both rails and platen-leaf or member may be elevated to allow the change of
position of the book, or the turning of the leaves. The construction described
provides for shifting the impression-receiving surface without displacing the machine
from the rails or support, or moving the same out of its normal path. It is only
necessary to continue the line spacing movement of the machine, or the movement
parallel with the tracks provided therefor, to dispose it beyond or outside of the
printing area, whereupon those members of the rails and platen which span the
printing area, and serve as the means of support for the machine when the latter
is in operation, may be moved or displaced, preferably without detachment, to
expose the printing area, and give free access to the space between the rests by
which the platen is upheld.
As hereinbefore indicated, however, it is not indispensible, in carrying out my
invention, that the rail-members shall be separate and non-alined. On the other
hand, I have found it desirable, under certain circumstances, to have the rail-
members constructed for permanent alinement, whereby the adjustment of the
main or operative members thereof is accompanied by a corresponding adjustment
of the auxiliary, or, as I have hereinbefore termed this feature, stationary"
members. For instance, in Figures 4 to 6, inclusive, the main and auxiliary
rail-members 17 and 18, are hingedly connected by a pivot-pin, 27, the auxiliary
or stationary rail-member having a joint stiffening or strengthening tongue, 28,
which is preferably flush with the under side of said rail-member, and is adapted
to be countersunk by fitting normally in a cavity 29, in the under side of the
member, 17. This hinge connection between the rail-members is shown also in
Figures 14 to 18, inclusive, but in Figures 16 to 18 the members, 17 and 18d, are
connected pivotally by a vertical pin, 29d, whereby the front or movable rail-
members are adapted to swing laterally in a horizontal plane, as indicated by the
dotted lines in Figures 16 and 17, to expose the printing area or field.
Also, in Figures 7 and 8 I have shown in connection with the hinged movable
rail-members, 17, a transverse connecting-bar, 30, having notches, 31, to receive
pins, 32, depending from said rail-members near their front ends, said pins pre-
ferably consisting of set-screws having heads, 33, and being threaded into sockets
in the under sides of the rail-members to clamp the connecting bar, 30, and the
rail-members at their points of intersection. It will be seen that the desired
notches, 31, of the connecting-bar may be engaged with the pins, 32, to hold the
rail-members at the desired relative adjustment at their front ends, and at the same
time enable the operator to lift both movable rail-members in one operation, as
by the thumb and forefinger of one hand, to leave the other hand free to move the
main platen-member, or to properly position the leaf or impression-sheet upon
the upper surface of the platen preparatory to again lowering the rail-members.
In the construction illustrated in Figure 16 the movable rail-members, 17ª, may
be held in their normal positions by means of spring or yielding stops, 34, or the
equivalents thereof, and it will be seen that the advantage in swinging the said rail-
members laterally is to suit the lateral swinging movement of the main platen-
members, 10d.

page_text: Finally, it will be seen that the essential features of my invention resides in the
construction of a typewriting machine support having two members or elements of
which one is permanently located outside of or beyond the printing field or area,
while the other is normally located to span the printing field or area, but is movable
into and out of said printing field or area, to provide for the arrangement of the
leaf or sheet which is to receive the impression, the first-named member or element
being adapted to receive and uphold the typewriting machine temporarily when
the latter is at rest, while the last-named or main support-member or element is
designed to normally uphold the machine when in operation.
Furthermore, it will be seen that the platen is not an indispensible element of
the mechanism described, for it has been demonstrated that, with suitable support-
ing devices, such as rails, spanning the printing field or area to be traversed by
the machine, printing may be done directly upon the surface of a book-leaf which
is unsupported throughout its area by a platen, but it is obvious that the result under
such conditions is not as satisfactory as when a firm backing is employed for the
leaf or sheet which is receiving the impression, owing to the yielding quality of
the book-leaves, particularly when they are in bulk, or when there is a considerable
depth of leaves.
In the same way, it will be understood from the foregoing description that the
rails as shown and described are not wholly indispensible, provided some means
are employed to guide the typewriting machine in traversing the printing field or
area, and provided that element which serves to support and guide the machine
while traversing the printing field or area is movable when relieved of the machine
to expose the printing field or area when it passes to a point beyond the printing
field or area to release said movable supporting element. But the result obtained
by the use of the rails, and particularly when those rails are loose, or are movable
independently of the supporting surface, such as the platen described in connection
with my apparatus, is far more satisfactory than when these members are omitted,
for the reason that the rail-members which span the printing field or area serve
to maintain the leaf or impression-sheet in its proper position upon the supporting.
surface or platen, and thus insure a sharp impression of the type-faces.
"
Moreover, in the drawings I have shown (see Figures 1, 9 and 11) a platen
which is adapted to support only one leaf or sheet and which, hence, may be termed
21 single" platen; but the features of construction which have been shown and
described are equally applicable to a double platen or one which is capable of
supporting the opposite pages of a book simultaneously (see Figures 12 and 16).
It will be understood, moreover, that various other changes in the form, pro-
portion and minor details of construction than have been specifically shown and
described, may be resorted to without departing from the spirit or sacrificing any
of the advantages of this invention.
