Still another and more specific object is the
provision of a scope having a guide strip with
embossed alphabetical or other characters there
on and a combination selecting handle and indi
25 cator operable to move the guide strip back and
forth across the scope table and also indicate the
selected letter and additionally indicate the total
number of characters selected forr` each line of

in the recess Il with the block I9 flush against
the bottom of the glass table. Depending from
the bottom crosswise frame member- 2l is a leg 25
block 2|, which serves when the folding leg Il is
extended to maintain the frame and table in a
conveniently slanted position for operation of the
device.
Each of the long-sided frame members 22 and 30
23 of the frame has an open-ended longitudinal
groove-24 (Fig. 5) for reception of a sliding tongue
25 on the offset section-connecting arms 29' of

ordinary scope and to permit the free use oi
ruling devices such as a T-sq'uare and the like.
The intermediate arch parts between the side
arms of each
U-shaped bracket section are
formed, by casting for example, in the shape of
combination lamp housings and reflectors 38 and
40 interiorly of each of which are lamps 39 and 4|
in sockets 39’ and 4|’. The upper socket 39' is
desirably removable and is secured in place by a
10 set screw 39” (Fig. 2). The lamps 39 and 4| are
connected by the usual lamp cord and may be
turned on together or separately as desired by
usual switch means.
_
In assembled relation, the main bracket sec
15 tions 29 and 32 are disposed to embrace the
scope board or frame across its lateral extent, as
seen in Figs. I_and 2, and are slidable longi
tudinally thereof upon unloosening set screws 21.
Between the opposite side arms 30 and 3| of
20 the lower bracket section 29, but above the frame
and glass, is a roller 44 having axial pivots 45
and 46 (Fig. 5) extended into the said side arms.
One (right-hand) end of the roller has a deep
recess or Well 41 in which is a coilfspring 48,
anchored to the roller at 49 and to the frame at
58. 'I'his roller has wound thereon a supply of
tracing paper or a non-ñbrous transparent stencil
`protecting sheet such as Cellophane, and when
the roller is rotated by unwinding the sheet ma
30 terial therefrom, spring 48 winds back and tight
ens the sheet over the underlying stencil sheet
or copy, as the case may be.
-At this juncture it is appropriate to point out
that a spring-urged clip or jaw 5| (Figs. 1 and 5)
is mounted centrally on the lower frame member
28 so as to clamp down against the latter and
thus hold a tracing sheet, stencil sheet and/or
a protective transparent cover sheet stretched
tautly over the glass table; for instance, in the
40 relation shown in Fig. 6, the transparent top
protective sheet being indicated at 52, the un
derlying stencil sheet at 53, the customary stencil
backing sheet 54, and between the stencil and
backing sheet, a tracing guide strip 58 (see also
45 Figs. 7 and 8).
It may also be observed that the top of the
stencil backing sheet 53 (Fig'. 5) is attached to
the top cross frame member 22 by means of studs
or screws 55 spaced apart on the frame and ñtted
50 into the usual anchoring apertures 56 in the
backing sheet.
.
In order to facilitate the speedy execution of
uniform stencil characters and copy, the inven
tion includes a lettering guide in the form of a
55 guide strip 58 (Figs. 5 to 9) of aluminum or
other impressionable material, on which are em
bossed alphabetical characters 59 in the central
region of the strip, these characters being flanked
longitudinally along opposite edges of the strip
by a series of spaced gear-engaging apertures 80
along the top edge, and a series of spaced clon
gated guide bosses 6| along the bottom edge.
Extended across the tableY or frame between
side portions of the lower bracket section 29 is
' a track strip (Figs. 5 and 6) composed of two
spaced strips 65 and 66, the former and upper
most strip having a longitudinally extensive
channel or track 61 in which the guide bosses -
6| of strip 58 travel to assure uniform back and
forth movement of the lettering strip by means
now to be described.
Referring especially t?
3s. 5 and 2, it will be
observed that the left-hand offset connecting arm
portion 29’ of the lower bracket section 29 has an
75 angled sidewi~ extension 18 positioned conveni
ently at one side of the scope table or frame for
easy access by the operator, and journaled in
this extension is a form of bevel gear 1| (Figs.
1, 2, 3) having a sleeve-shaft 12 which terminates
at its upper end in a cup or bell-shaped operat
ing knob 13 having a flat outer (axial) face 14
divided in thirteen evenly spaced sectors 15 (Fig.
4) and divided circumferentially into three zones
16 surrounding the central recessed portion 11 of
the cupshaped knob. Alphabetical letters or 10
characters are disposed in the several sectors de
fined on the face of the knob.
Fitted into the opening of the recess 11 of knob
13 is a tally disc 18 having thirteen equal and
serially numbered divisions around its periphery,
there being one such division for each division 16
on the knob or letter scale. However, the
markings of the tally scale are offset a half
division relative to the markings of the knob
scale.
.
Extended from the inner face of the tally disc
18 is an integral sleeve 19 (Fig. 3) which passes
through the sleeve portion 12 of knob 13 into
the bracket extension 10, where it is secured
against movement by a set screw 80. A pointer
arm 8| pivots around the knob face 14 on a short
shaft 82 which extends with the sleeve 19 of. the
tally disc, to a collar 83 set on the inner end 82’
of shaft 82 which collar 83 rides against ball
member 84 disposed between the collar and ex 30
tension 10 for movement into depressions 85
against the riding tension of a small spring 86
embracing an upper portion of shaft 82 between
the knob part of the pointer 8| and the tally disc
18, thus producing a ratchet effect to hold the
pointer in any adjusted position.
A semi-cylindrical hood 88 is attached at 89
to the bracket extension 18 and shields the upper
half of the bevel gear 1|. The teeth of the bevel
gear 1| are spaced and numbered in relation to 40
the spacing and number of gear tooth holes 60
in the lettering strip 58 proportionately to the
size and spacing of the alphabetical characters
thereon, in such manner that for every move
ment of the knob 13 one division 16 relative to
pointer 8| when the latter is positioned on one
of the tally divisions |, 2, 3, etc., the strip 58 will
move across the scope table a distance equal to
the width of one character or letter.
In the operation of the improved scope, the 50
table Aor frame is set up as it appears in Fig. 1,
and a stencil with its backing sheet is attached
on the screws or'hooks 55;` the backing sheet lies
against the glass and beneath the track strips
65-66, and the embossed lettering strip 58 rides
in the latter track (Fig. 5), while the bevel‘gear
1| engages the spaced holes 60 in the strip 58.
The stencil sheet 53 (Fig. 6) is placed over the
embossed lettering strip 58, and with the bracket
structure 26 slid down toward the bottom of the 60
frame or table, the Cellophane protective sheet
52 is fed off of the roller 44 and clipped beneath
the spring clip- 5 |, the roller. spring 48 being some
what tensioned by this operation.
Thereafter,
the bracket 26, together withl the lettering strip,
is moved to the top of the table as a unit, the
Cellophane sheet unwinding from roller 44 and
further tensioning spring 48.
\__
The operator now selects his ñrst alphabetical
character, let us say the letter A, by turning the 70
pointer 8| (Fig. 4) to the numeral | on tally disc
18, and thereafter, he turns the knob 13 until the
letter A in the outer sector 16 coincides with the
pointer, which indicates that the letter A is in
first- position relative to the left-hand margin of 75

being especially effective to this end, and by
rapidly brushing a suitable stylus against the
Cellophane cover sheet over the embossing of the
htter appearing in the first position, that letter
will be cut into the stencil sheet, by a displace
ment of the wax in the stencil'l sheet due to the

numeral 5 of the tally disc, and should be moved
to the next following number, 6. Having done
this, the operator simply rotates knob 13 until
the letter “I” coincides with the number 6 to
which the pointer arm has been set. The oper
ator then knows that the embossed letter which
now lies beneath the stencil sheet next to the
letter “C" in the as yet incomplete word stencil,
will-be the next required letter “I”, and he pro
25 ceeds to rub with his stylus the Cellophane cover
sheet in the space immediately to the right of
the last letter “C” in this incomplete word, thus
cutting the next required letter, after which the
