HENRY E. BYRNE, OF TYLER, TEXAS.
TYPE-WRITER LINE-SHIFT.1,185,4'76.
Specification of Letters Patent.
Patented May30, 1916.
Application filed December 18, 1915. Serial No. 67,636.
To all whom it may concern:
Be it known that I, HENRY E. BYRNE, a
citizen of the United States, residing at
Tyler, in the county of Smith and State .of
5 Texas, have invented new and useful Im-
provements in Type-Writer Line-Shifts, of
which the following is a specification.
. This invention relates to line shift attach-
ments for typewriting machines and it con-
10 sists in the novel features hereinafter de-
scribed and claimed.
An object of the invention is to provide
an attachment of the character indicated
which when applied to the typewriter per-
15 mits of the use of the machine wherein a
stenographic effect or principle is obtained.
By use of the attachment -a system of
shorthand writing may be had with a type-
writer machine fully as. well as with a pen
20 or pencil now generally used. By use of
the present attachment the point of writing
on the platen of the typewriter may be va-
ried to a definite point so that the letters
or characters will be produced on the paper
25 at points above or below the regular line of
writing. When any letter or character in
the line of writing appears above or below
the regular line of writing, it becomes a
word or phrase sign, and the fact that it is
30 above or below the line indicates positively
that the letter or character is used as a word
or phrase sign.
With these objects. in view the attach-
ment in the present instance comprises a
35 lever pivotally connected with a lug which
may be attached 'to the frame of the type-
writer, and which carries a key and also
means for straddling the shift key of the
typewriter and a roller engageable with the
40 said shift key. A link is pivotally con-
nected at one end with the lever and at its
other end is pivotally connected with an ear
which may be slidably connected with the
frame of the machine. If desired or nec-
45 essary a spring may be interposed between
the ear and the lever and is under tension
with a tendency to normally hold the free
end of the lever toward the ear.
In the accompanying drawing: Figure 1
50 is a detail sectional view of parts of a type-
writer showing the attachment applied and
the parts in one position. Fig. 2 is a simi-
lar view showing the parts in another posi-
tion. Fig. 3 is a detail view of a sample
55 of the writing produced showing the rela-tive positions in which the characters may
be. produced from the same type.
As illustrated in the accompanying draw-
ing the attachment comprises a lug 1 adapted
to be secured to the frame of a typewriter .60
and to which a lever 2 is fulcrumed. The
lever 2 is provided at its free end with a key
3 and also with approximately parallel bars
4 adapted to lie at the opposite sides of the
shift key 5 of the typewriting machine. A 65
roller 6 is journaled between the bars 4 and
rests at its lower side upon the upper edge
of the shift key lever.
A link 7 is pivotally connected at one end
with the lever 2 at a point between the ends 70
thereof and the said link at its other end is
pivotally connected by means of a loop with
an ear 8 connected with the frame of the
typewriter. ' The connection between the
link 7 and the ear 8 is sufficiently loose to 75
permit the link to have slight longitudinal
movement without moving the ear. The ear
8 is provided with a slot 9 which loosely re-
ceives a screw 10 usually provided upon the
frame of the typewriter, in a manner where- so
by the said ear may move with relation to
the screw and the frame of the typewriting
machine, but when the said screw is tight-
ened the said ear is secured at an adjusted
position on the frame. A spring 11 is em- 85
ployed and one end of the spring is con-
nected with the free end portion of the lever
2 and the other end of the said spring is
connected with the ear 8. The spring 11 is
under tension with a tendency to hold the 9o
free end portion of the lever 2 toward the
ear 8 when the attachment is applied to a
typewriting machine.
When the attachment is applied to a
typewriter the parts are so arranged that 95
.the contact of the roller 6 with the upper
edge of the shift key lever 5 normally holds
the said key in a slightly depressed posi-
tion whereby the platen of the typewriting
machine is held slightly above its normal 100
position when the attachment is not used..
Therefore, when the small letters or charac-
ters are produced upon a sheet of paper
placed upon the platen the said letters ap-
pear along a certain line. When it is de- io
sired that one or more of the letters should
appear above the said line, the lever 2 is
swung whereby the shift key 5 may assume
its uppermost position and consequently
the platen is lowered and the character or no
