Improvements in and relating to Type-writing Machines.
We, SAMUEL COLLINS of 22 32 Catharine Street Philadelphia in the County
of Philadelphia and State of Pennsylvania United States of America, Gentleman,
JOHN BERESFORD LOVE and SAMUEL ARTHUR LOVE both of No. 500 Locust
Street Philadelphia Pennsylvania United States of America Manufacturers 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:-
Our invention relates particularly to the figures on the key board, and on the
printing types of these machines, and is designed to facilitate and expedite the work
thereof, and it also relates to fonts of type used in printing.
Our invention consists in combining the number indicating the numerator and the
diagonal stroke in one type, and, when applied in a type writer, in one type, and
one key of the key board, so that they occupy only the same space usually occupied
by one full sized letter or figure. We employ a line of small sized figures, 1, 2, 3,
4, 5, 6, 7, 8, 9, 0, as well as a line of large sized similar figures. The line of small
figures is used to indicate the denominators and the fraction is thus distinguishable
from the ordinary lines of figures.
In the drawings
Figure 1 represents a perspective view of a caligraph type writing machine,
showing also my improved key board.
Figure 2 is a detached plan of the keys, showing the letters, figures and part-
fractions on the keys.
Figure 3 shows a detached type with a small numeral 7 on its face, also a type
with small numeral 2 and diagonal line extended slightly beneath it, which with
the small numeral 7 will represent two sevenths. These being type markings are
in reverse.
Figure 4 shows simply the connection-rod between the type and the key and
Figure 5 shows the impression made on the paper by a type, such as will form
numerator and incline stroke, as in Figure 3, and a large figure 5, and the results
of two strokes from type shown in Figure 3 combined, making five and two
sevenths.
The general construction of the machine shown, and other analogous machines,
is well known in the arts, and we will confine our description to the feature wherein
our improvements are made; these being the markings on the keys and on the
printing types.
A is a fine of keys with the large, ordinary-sized figures 1 up to 9 and 0; B B lines
of letters; C a line of small figures adapted to form denominators to supplement my
small sized numerators and inclined strokes; D a line of numerators from 1 to 9 in
small figures, with the inclined strokes alongside and extended slightly beneath
them, each figure and stroke taking up no more than the space occupied by one
whole figure, and being on one type-face and on its one corresponding and
connected key.
E, E are types, Fa key. The keys containing the small separate figures in
printing can be struck to follow any figure or numerator with its inclined mark and
be followed by small sized figures until the size of the denominator is indicated thus
enabling an operator to write a denominator of any required size.
We contemplate applying our invention to fonts of printing type.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same as to be performed we declare that what we
claim is
$3.1
1. In a type writing machine, a key board containing keys, the faces of which
are marked with ordinary sized figures and keys, the face of each of which is marked
with a combined small sized figure and an incline mark or stroke alongside and
extended slightly beneath it, in combination with a set of impression type corre-
spondingly separately marked, and connected with said keys, substantially as
.described.
2. In a type writing machine, a key board containing keys of which are marked
with ordinary sized figures and keys the face of each of which is marked with a
: combined small sized figure and inclined mark alongside and extended slightly
beneath it, in combination with a line of keys the faces of each of which are marked
with small sized figures, also in combination with said keys a set of impression types
correspondingly separately marked, and connected therewith, substantially as
described.
3. In a type writing machine a key-board, in combination with a set of impression
types cach separately marked with a figure for a numerator and an inclined stroke'
or mark and connected with the keys by bars, substantially as described.
4. In a type writing machine, a key board in combination with a set of impression
types some of which are marked with ordinary sized figures, and others with a
figure for a numerator and an inclined stroke, said type being connected with the
keys or bars, the figures and strokes on the separate faces of said types so marked,
being restricted in size, so as to take up no more space when printed than that
necessary for the separate impressions of the ordinary sized figures, substantially as
described.
