PROTECTING DEVICE FOR {TELEPHONE
TRANSM'ITTERS ‘
Maurice Rubel, Chicago, Ill.
Application January 11, 1935, Serial No. 1,392
2 Claims. (Cl. 179-185)
This invention relates to a protecting device
for the transmitter of a telephone and the like,
and more particularly to a device for feeding a
long strip of paper before the mouth of the
5 transmitter upon repeated manipulations.
A considerable number of caps and other pro
tecting devices for the transmitter of a tele
phone have been devised to prevent the spread of
disease through the use of public telephones;
10 however, as far as I am aware, no device has been
found acceptable or satisfactory. The difficulty
of dispensing caps or short strips of paper and
the accumulation of waste caps etc. after use
have made such plans undesirable.
An object of my invention is to provide means
16
whereby a fresh strip of paper can be fed with
a modicum of effort into position bridging the
‘transmitter mouth, and means for compactly
storing the waste strip until a time when it may
20 be conveniently disposed of.
A further object
is to provide means for preventing waste of
the paper during the time that the telephone
is being used. A still further object is to provide
automatic means for feeding fresh paper areas
26 each time the telephone is used. Other speci?c
objects and advantages will appear as the speci
?cation proceeds.
_
The invention is illustrated, in a preferred
embodiment, by the accompanying drawings, in
30 which-—
Figure 1 is a, front view in elevation of a
telephone transmitter equipped with a device
embodying my invention; Fig. 2, a side view in
elevation; Fig. 3, a sectional view, the section
35 being taken as indicated at line 3 of Fig. 2; Fig.
4, an end view of the lower cylindrical casing,
the cap being removed, the view being indicated
by the line 4 of Fig. 3; Fig. 5, a view similar
to Fig. 4 of the opposite end of the cylindrical
40 casing, the view being taken at line 5 of Fig. 3;
Fig. 6, a transverse sectional view of my device,
the section being taken as .indicated at line 6
of Fig. 2; and Fig. '7, a side view in elevation
of a modi?ed form of the invention in which pa
46 per is fed automatically upon movement of the
receiver hook, the end cap of the lower cylindri
cal casing being removed.
In the illustration given, A designates the tele
phone stand equipped with a receiver hook A’;
50 B, a receiver; and C, the transmitter. In view
of the fact that such construction is well known,
a detailed description is believed unnecessary.
My attachment mechanism comprises a rear
metal wall III which is centrally perforated to
55 receive the rear end of the mouthpiece II; that
is, the mouthpiece II is ?rst removed and then
after being passed through the central apertured
plate II], is screwed ‘within the drum casing I_2.
Secured to the rear side of plate In is an annu
lar socket I3 adapted to receive the drum I2.
Screws I4 are passed through the socket member
I3 and engage the drum casing I2 to secure the
attachment rigidly to the drum casing. Soldered
to the ends of plate 'IIJ are the upper cylindri
cal casing I5 and the lower cylindrical casing 10
IS. The casings are provided with caps I5avand
I6a~ respectively. Casing I5 is provided with a
slot H which runs to the extreme open end of
the casing, and likewise casing I6 is provided
with a slot I8 which runs to its extreme open 16
end. ‘Thus, when the caps I5‘1 and IIia are re
moved, the slots ‘I1 and I8 permit the rolls of
paper inside to be removed with a web of paper
connecting, the rolls. Connecting the casings
I5 and'll? is a metal platen member I9 having
its sides turned‘ inwardly'to provide U-shaped
guides 25 receiving the edges of the paper. The
platen is provided with openings 2| in its cen
tral portion and ‘adjacent! the mouth II' of. the
transmitter.
'
I
‘
,
I
25
The upper cylindrical casing, I5 receives a. sim
me roll 22 containing paper 23. ‘The roll or '
spool 22 is provided'with sides 23. The paper
from the upper spool 22 passes through the slot
‘
I‘! over the platen I9 and is attached to a lower 30
spool 24, which is equipped at one end with
an operating wing or thumb button 25. ' The
lower spool 24 is preferably equipped with an
inclined spring stop member 26 which is adapted
to engage‘ a ?xed abutment 21, as shown more 35
clearly in Fig. 4, to prevent the spool from being
turned in an unwinding ‘direction.
‘
It will be observed that the winding handle
25 is disposed on the same side of the tele
phone stand as the receiver B. Thus, when
the telephone is being used, the user of the
telephone having the receiver grasped in his left
hand, is unable to reach and manipulate the
handle 25. This prevents the user from wantonly
operating the mechanism to use up the paper 45
supply. In view of the fact that the paper roll
may contain advertisements, there would doubt
less be a tendency for the user of the telephone
to wind up the bottom roll while telephoning, if
50
this could'be done conveniently.
If desired, additional means may be provided
for preventing the user of the telephone from
winding the bottom roll.
As illustrated more
clearly in Fig. 5, the inner end of the spool roll
may be equipped with a ratchet gear 28. A 65

28 by a spring-pressed pin '30. The pawlii29 is r of platen l9. In inserting the lower spool '24,, "1 »

ton 3] so as'to depress the pawl 29 until the
ratchet 28 is in alignment therewith. 'The caps‘
l5a'and l?a may then'be placed in position‘ and .
. the device isready for'operation.
When auser '
reaches the ‘telephone, he ?rst depresses the but
