TYPEWRITING MACHINE‘
Burnham O. Stickney, Hillside, N. J., assignor to
Underwood Elliott Fisher Company, New York,
N. Y., a corporation of Delaware
Application October 18, 1933, Serial No. 694,041
10‘ Claims. (Cl. 197-186)
This invention relates to the frames of stand
ard full-size typewriting machines.
This invention is in the non-portable ?eld of
heavy-duty typewriters which are usually at
> 5 tached to a desk.
In this ?eld, there are prob—
lems none of which is touched upon in the port
able typewriter art. The carriage usually sur
mounts the standard machine, and overlies the
type-system; whereas, in the portable, the car
10
riage usually runs in a niche at the back lower
portion of the machine, behind the type-bars. It
is customary in the standard machine to pro
vide a heavy self-sustaining main frame, which
usually includes four corner-posts, and upon these
posts are usually mounted the front and rear
tracks for the carriage.
These frames are usually cast iron, and are
expensive to ?nish and also expensive to carry
in storage after ?nishing, owing to their great
20 bulk and weight. In solving this problem, this
invention has avoided the necessity for ?nish
ing the principal portion of the heavy frame,
and at the same time has improved the appear
ance of the machine and made the main frame
25 better adapted for attachment thereto of many
of the working parts of the typewriter. These
working parts are usually attached by screws,
bolts and other devices, which heretofore have
been inaccessibly put out of sight within the base
of the frame, but, according to the present in
vention, they project conveniently right out from
the sides of the frame, and are fully exposed and
accessible; while at the same time the machine
is more freed from unsightly projections and
mountings than heretofore, and is thus rendered
35
more attractive.
According to- the present invention, the main
frame is provided with un?nished exterior bosses
and projecting parts which are encased by the
sides of a sheet-metal mask or outer frame. The
4 O typewriter has corner-posts, and these corner
posts are encased by the corner-portions of the
mask or outer frame, and attractiveness, great
rigidity and stability and harmony are secured,
and the machine is rendered more salable.
45
The mask or outer frame is so made and placed
that it occupies a position below the shoulders
which in the Underwood typewriter spread up
50
wardly from the main frame and carry the car
riage-tracks. The mask or outer frame is made
to harmonize with these projecting shoulders,
and a smooth, unitary and attractive ‘ appearance
5.5
is gained, a flush unbroken surface being pre
sented where the shoulders rise above the upper
edge of the mask.
One of the features of the present invention
pertains to masking the body of such a main
frame, to cover the unsightly screws and projec
tions usually present in the sides and elsewhere
in the main frame; while the carriage-track
supports may project above the mask, but com
bine harmoniously therewith. The mask or outer
frame may be inexpensively and readily at
tached and removed, and present a smooth,
unbroken, ?nished surface, at the sides and front
of the typewriter, to harmonize with the over
head carriage, and present an attractive uni
tary box-like appearance.
The main frame may be cast in one piece, and
include the forward open framework which hems
the keyboard, and the mask or outer frame may
be struck up from sheet-metal and include side
walls and a member that extends forwardly
therefrom to enclose the open keyboard-frame
portion.
20
At the bottom of the side walls, the sheet
metal is bent inwardly to form ears to fasten up
against the under sides of bosses, and screws
hold rubber feet up against said cars, so that the
mask or outer frame is ?rmly secured, and yet 25
readily detachable.
In this form of the invention, the corner-posts
of the frame are covered by the mask or outer
frame, which may present a smooth unbroken
vertical wall from the extreme rear to the front 30
of the machine.
At the rear ends of the side walls, the mask
or outer frame may be bent inwardly to form
rear vertical plates which are fastened by screws‘
to the rear edges of the side walls of the main 35
cast
frame.
The
latter
is
self~sustaining
throughout, and'the mask is a ?nishing mem
her.
At the front the upper edges of the side walls
may be bent inwardly to form vertical front
plates; and at the top the upper edges of these
portions of the mask or outer frame ?t within
shallow recesses cut in the ~main frame, so that
a flush or unbroken surface is presented where
the carriage-track shoulders rise above the mask. 45
At the rear the carriage~track shoulders pro-;
ject outwardly through upper cutaway-portions’
in the side walls of the mask or outer frame, and
present a harmonious appearance.
A front vertical plate extends from side to side 50
of the mask, just in rear of the usual keyboard,
the same having an arc-shaped upper edge bor
dered by short tablet-portions, this front mask
being ?ush with the side plates that are turned in
wardly from the side of the members of the
2
2,108,832
mask or outer frame. The front plate may be se
cured partly by means of screws passing through
hidden ears pendent from the plate, and partly
by means of top screws fastening down the rear
portions of said tablets.
The front extending frame of the mask or outer
frame has inwardly-turned beads or ?anges which
may ?t over the underlying frontwardly-extend
ing ?ange-portions of the main frame.
10
One of the valuable features of the main cast
frame‘is the formation of strengthening ?anges
upon the outer sides of the Walls, strengthening
the castings and making them easier to mold and
cast and ?nish. The screws which usually pass
Referring to Figure 1, the main iron frame of
the machine may be cast in one piece formed
of side walls I0, front wall ll, rear wall l2, front
and rear side posts I3 and I4, and upper side
bars l5, joining the tops of the posts.
In the typewriter-frame, it has been the prac—
tive to cast the side walls of the base with integral
?anges which are turned inwardly. This proves
to be an objection in manufacturing, but it con
duces to a pleasing appearance of the machine. 10
According to the present invention, the side walls
H] are placed at the inner portions of the base,
as seen best at Figure 6, and their top ?anges l6
15 through the side walls, are mounted in bosses
project outwardly, thus reducing the cost of
which project from the side walls beneath the
desirable structure. The side walls below said
outturned ?anges are formed with various bosses
l1, through which pass fastening screws 33 for
inner members I8, I 9 of the frame, or for securing
other supports for the interior working parts of
the machine.
The posts, the base, and the top side bars
may all form a single casting, from which may
project suitably formed exterior bosses I‘! where

have outwardly-turned ?anges which merge with
the ?anges of the side walls, and the portion of
20 the casting which surrounds the keyboard has
also outwardly-turned ?anges.

All of the bosses are accessible 25
and readily machine-?nished.
There’ is usually included a platen-shift rail
which projects at the sides of the machine and

In some kinds of machines, the main cast frame
may be provided at the front keyboard—portion
with inwardly~turned ?anges, and it may also
have corner-posts with outwardly-turned ?anges
cast'upon the side walls, and upon the corner
posts, and upon the top bar which connects said
40 posts from front to rear. At this portion, this
kind of machine may be masked by a simple side
panel seated in between the posts and covering
the ?anges and screws and bosses, and also cov
ering the upper bar, so as to present a highly
45 ?nished, smooth surface devoid of cuts or breaks,
between the usual side posts of the machine.
Other features and advantages will hereinafter
.appear.
In the accompanying drawings,
Figure 1 is a side elevation showing a standard
Underwood typewriting machine, having an im
proved frame-casting masked according to the
present improvements.
Figure 2 is a perspective of the sheet-metal
55 mask or outer frame seen at Figure 1.
This ?g
ure shows also track-supports projecting up
wardly from the main frame at the sides of the
mask.
Figure 3 shows a main frame casting, resem
60 bling partly the Figure 1 construction and partly
the old standard construction. Figure 3 shows
the usual side posts, and the portion of the frame
between them is masked; the remaining portions
being exposed.
65
Figure 4 is a perspective view to illustrate the
improved form of the cast side portions of the
typewriter-frame seen at Figure 3.
Figure 5 is a perspective of the mask seen at
Figure 3, forming a panel between the side posts
of the main frame casting.
Figure 6 is a sectional front elevation, showing
the construction at Figure 3. The base of the
main frame has an outturned upper ?ange, as
shown at Figure 1. Figure 6 may be read upon
75 Figure 1, as well as upon Figures 3 and 4.
The posts may be provided with outwardly~ 30
?anges l6, and the same may be further continued
at 22 upon the top side bars l5; also at 23 upon
the rear edges of the rear posts, and at 24 upon
the front edges of the front posts.
35
From the ?ange It may be continued down
wardly a brace 25‘merging into horizontal bosses
2B for the front feet 28 of the typewriter. A boss
or ?ange 21 is formed for each of the rear feet
28.
40
Said side ?ange I6 may be continued forward
ly and downwardly at 29 to merge into the ?ange
30 projecting from the front of the vertical wall
I i of the base, forward of the usual keyboard 32.
All said ?anges, as well as all the fastening
screws 33, may be covered by opposite side walls
34, 31 of thin sheet-metal struck-up mask or
outer frame, Figure 2; the vertical side walls of
said mask continuing forward at 35, and being
bent at the front to form a front masking por
tion 36 for the ?anged front of the typewriter 50
frame casting. Said side Wall 34 and said front
wall 36 are preferably formed in one piece with
the opposite wall 31, which is symmetrical to 34.
Each of the side walls and front wall of the 55
mask or outer frame may be formed with in
wardly-turned ?anges 38, 39, 40, 4| and 42, at
the rear, top and front of the main side portion,
extending downwardly to the U-shaped front
keyboard-framing cross-portion of the mask. 60
The portions 38 mask the rear posts I4 of the
main frame and are fastened thereto by top and
bottom screws 38*‘.
The opposite side walls 34 and 31, as described,
are symmetrically formed and placed. The fac 65
ings 34 and 37 mask the ?anges and screws,
bosses, etc., that are exposed on the sides and
upper portions of the casting when the mask
is removed.
Each side of the mask or outer frame has
bent-in bottom ears or ?anges 44, which are
fastened by the same screws 45 which hold the
rubber feet 28 up in place upon the casting 26,
27; the heads 46 of said screws being received
75
5,108,832
in recesses 41 formed in the bottoms of the rub
ber feet.
In the tops of the side portions of the mask
or outer frame are formed depressions 48, to
afford room for the play of the usual carriage
shift rail; but, except for the depressions, the
top ?anges of the side masking members 34, 3'!
may be made level, conducing to neatness.
The mask or ‘outer frame or covering ?ts
around all except the usual topmost portions of
the usual main frame casting. These top por
tions consist of shoulders 49, 50 which form
ridges coextensive with the outer surface of the
mask overhanging the corner-posts and which
15 rise from the mask to carry the front carriage
track; and rear shoulders 51 rise above the mask
to receive the rear carriage-track 52.
The car
riage 53 is of usual construction to carry the
platen 54.
20
'
It will be seen that the mask or outer frame
or covering, with its smooth, unbroken main sur
faces, affords an ornamental covering for the
main casting below the overhanging carriage 53.
The side plates 34, 31 of the mask or outer
25 frame or covering are connected by a detach
able front vertical masking plate 55, having a
curved cut-out upper edge at 56, corresponding
to the curvature of the row of types usual in an
Underwood machine.
At the ends of the front plate 55 may depend
30
ears 51, fastened by screws 58 to lugs 59 upon
the main casting. The top of the front plate
at each, side is bent back forming a tablet 60E,
fastened by screws 60 to the main casting.
35
At Figures 3, 4 and 5, the main casting is
formed with the usual front and rear side posts
6|, 62, and the usual cast front frame 63 extends
forwardly from the post BI and encloses the key
board. Between the posts GI and 62, on each
40 side of the machine, is placed a mask-panel 64
to cover up the various screws 33 and bosses
I‘! which support the typewriter-parts within
the base, and also to cover up the top- ?ange l6
which projects outwardly from. the vertical wall
45 I0 of the base.
The ?ange 16, at Figures 3 and
4, is continued upwardly at 66 for the front post
and at 61 for the rear post, and these merge
into side walls 68, the latter preferably having
parts out out at 69, 10.
The panel 64 may be retained by upper screws
‘H fastened down through inwardly-bent ?anges
12.- The masking panel may also have a bottom
?ange 13, which is fastened up by screws 14
against the bottom of the base.
55
A brace-rod 15 extending from side to side
of the machine may connect the upper side walls
68 in Figures 1 and 3, and may be secured by
screws 16 passing through the side walls I5, 68.
At Figures 2 and 6, there is depicted a ribbon
60
shaft winding button 11 projecting through the
side plate of the mask.
Variations may be resorted to within the scope
of the invention, and portions of the improve
ments may be used without others.
