'I'his invention relates to a copy holder for
typists and has for its principal object the pro
vision of a neat, eiiicient compact foldable device
which will hold the material to 'be copied in an
5 easily visible position and which will successively
indicate the line to be copied as the copying pro
Another object of the invention is to provide an
efûcient mechanism which can be- rapidly oper
lß ated by finger pressure to move the indicating
gauge accurately along the work and to provide a
gauge which will indicate line `lengths and line
positions on the sheet lbeing copied so that an
exact duplicate may be made.
Other objects and advantages reside in the de
tail construction of the invention, which is cle-`
signed for simplicity, economy, and eiiiciency.
These will become more apparent from the fol~
lowing description.
‘ In the following detailed description of the in
vention reference is had to the accompanying
drawing which forms a part hereof. Like nu
merals refer to» like parts in all views of the draw
ing and throughout the description.
In the drawing:
Fig. 1 is a perspective View of the improved
copy holder, as it would appear ready for use.
Fig.` 2 is a rear view thereof with the sup
porting arms or legs in the folded position.
Fig. 3 is an enlarged detail section taken on
the line 3_3, Fig. 1.
‘FigJl is an enlarged side elevation of the line
The invention consists of a backing board or
plate I il, turned outwardly along its lower edge
to form a projecting shelf I I. On the back of the
plate I0, adjacent each vertical edge thereof, a
toothed rack bar I2 is positioned. The upper
extremities of the rack bars I2 support hinge
40 arms I3 and the latter support a paper clamp
bar I4 across the upper front of the plate I0.
The clamp bar I4 is constantly pressed against
the plate by means of tension springs I5 acting
upon lever extremities on the hinge arms I 3.
The lower extremities o_f the rack bars I2 are
formed into bracket members I6, to each of which
a supporting arm I'I is hinged. The outer ex
tremities of the arms are provided with rubber
cushions I 9*.
At their bottoms, the rack bars I2 terminate
in legs 20 provided with suitable rubber cushions
2|. The weight of the device rests upon the
legs 2U and it is supported in an inclined vertical
position by the arms I 'I which project rearwardly
55 at an upward angle.
The brackets I6 also provide a support for
hingedly supporting a pair of side arms 22 which
extend forwardly of the shelf II and terminate
in a line-spacing bar 23. The line-spacing bar
extends across the plate I0 immediately in front
of the shelf I I. A coil spring 24 supports the line
spacing bar in the raised position until depressed
with the finger. Two stop bosses 25 and 26 are
formed on each of the bracket members I6 to
limit the upward and downward arc of movement -10
of the line-spacing bar. A rod 27 is connected
with one of the side arms 22 and extends upwardly
therefrom alongside of, and parallel to, the rack
bar I2.
A line gauge plate 28 extends entirely across the 15
front of the plate I 0, and terminates at its ex
tremities in terminal brackets 29 which overlap
the edges of the plate I G to maintain the gauge 28
in place thereon. A pinion shaft 3U extends across
the back of the plate I6 ‘between the brackets 29
and carries two pinions 3| ñxedly secured 20
thereon. The pinions 3| engage the teeth of the
rack bars I2 and, since they are ñxed to the
shaft 30 constantly hold the gauge 28 Vin a hori- `
Zontal positio-n.
A lever 32 is rotatably vmounted on one ex-
tremity of the pinion shaft 30. 'I‘he lever 32 has >
an opening for the passage of the rod 2l. This
opening is of a size to allow the rod 2l to slide
freely through the lever 32 whenthelatter is 30
positioned at right angles to the rod but when
the lever is moved out of right angular position,
the side of the opening grips the rod 2l. A leaf
spring 33 is secured to the lever and acts against
the gauge plate 28 to constantly urge the forward extremity of the lever 32 downwardly so
that it will grip the rod 21 when the latter moves
When the rod 2l is moved upwardly, it lifts the
lever 32 to the right angle position and allows ¿o
the rod to slide freely therethrough without rais
ing the gauge plate 28. A finger bracket 34 pro
`jects from the gauge plate immediately alcoveV
the lever 32 so that the two may be grasped by
the fingers to lift the lever to the released position 45
to allow the entire gauge plate to be adjusted or
raised to the top of the rack bars.
In use, the typist ‘suspends the sheet to be
copied from the paper clamp I4 between the
gauge 28 and the plate I0. She then releases the 50
gauge plate by lifting the lever 32 and moves it
to a position below the first line to be copied.
When this line has been copied, she strikes the
spacer bar 23 with the lingers. This causes the
rod 21 to pull downwardly on the lever 32 and 55
move the gauge downwardly a line space so that
-the next line to be copied will be visible. This
operation iscontinued to the bottom of the sheet.
The gauge plate 28 is preferably formed with a
sight’opening 35 below which is a letter kspacing
scale 36. It is preferred to view the line to be
copied through this opening immediately above
the scale 36 Vsince this concentrates the vision
Von the line being copied. The upper edge of the
gauge 28 however can be used for'this purpose
if desired, as itis provided with a second'letter ‘
spacing scale 31.
The .spacing scales are in
dexed 'similarly to the scales of an ordinary'type
Íwriter so that the operator can read the line posi
15 tions on these scales and set her tabular stops to
correspond therewith.
