TOWEL DISPENSING APPARATUS
Romain De Bersaques, Seattle, Wash., assignor
to Steiner Sales Company, Chicago, 111., a cor
poration of Utah
Application May 17, 1934, Serial No. 726,085
12 Claims. (Cl. 312-—38)
This invention relates to improvements in ap
paratus for dispensing toweling and more par
ticularly to a type of apparatus in which a loop
of toweling is normally maintained outside of the
5 cabinet, and in which towel delivery is obtained
as the result of pulling oi the towel by the user,
and in which the soiled toweling is taken up by
a roll, also as the result of such pulling of the
towel by the user. The two rolls normally travel
10 ing at an equal speed, the depending loop is
maintained at a predetermined length.
An object of the invention is to provide means
for normally operating the feed roll and take
up roll at equal speed and ‘further to provide
15 means to be automatically conditioned as a result
of such normal operation for subsequently auto
matically simultaneously rotating the feed roll
and take-up roll to the end that the depending
loop and the entire unused end portion of the
20 towel is drawn wholly within the cabinet, so that
it will be no longer visible or accessible to the
user.
A further object is to provide means for auto
matically rotating the feed roll and take~up roll
25 at equal yet accelerated speed to take up the de
pending loop and unused end portion of the towel,
thus eliminating the danger of catching the
hand of the user between the bottom of the cabi
net and the web of- the toweling.

accelerated action of the take-up and feed rolls
to draw the depending loop into the cabinet.
Features include all details of construction
along with the broader ideas of means inherent
in the disclosure or illustrated or described 5
therein.

by means of a bell crank 65 having an upstand
ing arm 96 terminating in a right angled lug
61 which traverses the horizontal slot 68 of the
drop bar 6| and upon which the drop bar is
seated. The bell crank 65 is loosely mounted upon
the transverse shaft 1|v which is rotatably jour
naled in the plates 8 and 9 adjacent the hor
izontal clean towel roll supporting bottom I2.
It will be noted by reference to Fig. 2 that the
lug 91 is positioned slightly over the center‘ to
the left of the shaft 1| thus preventing accidental
displacement of the drop bar 6|. A trip arm 13 is
secured to the shaft 1| preferably in the center
thereof as shown in Fig. 6 and is adapted to

until they assume the positions shown in Fig. 5
wherein the roll of clean toweling is practically
exhausted. The bell crank 65 has a forwardly
extending arm 11 terminating in a right angled
lug 18 which lies in the path‘ of the arm 15. It
will also be noted that the trip arm 13 has a
downwardly extending portion 19 as viewed in
Fig. 5 having an edge which contacts with the
30 clean towel web adjacent the forward edge BI
of the false bottom I2. This portion 19 may
be of substantially less width than the towel web
and the tension of the web and the proximity
of the edge of the portion 19 to the edge 8| pre
vents further drop of the trip arm until the clean
toweling is entirely exhausted. When the‘end of
the towel passes the contacting edge of the trip
arm 13 the trip arm falls to the position shown
in Fig. 7, the arm15 which is also secured to
40 the shaft 1| strikes against the lug 18 of the
bell crank 65 thus moving the supporting lug t1
which traverses the slot 68 of the drop bar over
the center to the right of the shaft 1| whereupon
the drop bar 6| will fall. As the drop bar 9|
45 falls a beveled cam lug 83 secured to the drop
bar 6| moves the yoke member 85 from the posi
tion shown in Fig. 3 to the position shown in
Fig. 4. I The yoke member 85 is pivotally mounted
as at 86 to the side plate member 9. A pair
50 of rollers 81 are mounted on the yoke member
85 and are adapted to bear against the outer face
of the clutch member 4|. A lateral extension
88 of the yoke member 85 extends rearwardly
and lies in the path of the cam lug 83 as shown.
55
The drop bar 6| is also provided at its upper
end with a lateral extension 9| adapted to strike
against the arm 92 of the dog 55 thus moving the
hook 56 out of engagement with the ratchet teeth
of the member 31. Simultaneously the arm 93
60 of the dog 55 moves into engagement with the
latch 59 and moves it out of engagement with.
the member 31. The drop bar ISI. having moved
the clutch member 4| into engagement with the
ratchet member 31 by means of the yoke mem
65 ber 85 and the locking dogs having been moved
out of engagement with the ratchet teeth of the
member 31 the stored up energy of the spring
5| is now utilized to rotate the member 31 and
likewise the clutch member 4| in a clockwise di
70 rection and thus operate the feed and take-up‘
rolls I9 and 29 to draw the depending loop and
unused end of the towel within the cabinet so
that the entire length of toweling will be wound
upon the soiled towel roll and may be thus re
75 moved by the attendant with no waste of time.
A means for visible indication of the approxi
mate amount of clean toweling still remaining in
the cabinet is provided by a segment 95 pivoted
as at 96 and having suitable indicia on its pe
riphery as at 91. An arm 99 secured to the pivot
shaft 96 is connected to the arm 15 by means of
the rod 99. As the. arm 15 and the trip arm 13
move together as the roll of clean toweling'di
minishes the segment 95 will be rotated in like
manner. An aperture It! in the door 9 is pro
vided for notingv the reading on the segment 95.
Thus, the indicator is operated by the same trip
mechanism which winds up the end of the towel
and the gradual descent of the trip mechanism’
to its operative position gradually moves the in
dicator to show the approximate amount of
clean toweling left in the cabinet.
Means are provided for locking the rolls against
rotation should a maliciously inclined person out
the towel web and attempt to withdraw the towel— 20'
ing from the cabinet. Such means are shown
in Figs. 1, 6, 10 and 11 wherein the cross shaft
28 is provided with a depending flap 21 which
assumes the position shown in Figs. 1 and 10
during the normal towel dispensing period. ,An 25
arm I02 is secured to the shaft 28 exteriorly of
the side plate 3 and assumes the position shown
in Fig. 10 during normal operation of the cabi
net. The ratchet I93 is shown formed integral
with the usual ratchet I94 which is secured to 30
the shaft 44 of the take-up roll 29. The usual
dog I95 prevents backward rotation of the take
up- roll. Should the web of toweling be cut the
tension of the toweling is released to allow oscil
lation of the flap 21 which will assume the posi
35
tion indicated in Fig. 11, being moved'to such
position because of the weighted arm I92 which
is secured to the shaft 28. The arm I92 has an
oifset portion I68 which is adapted to engage the
teeth of the ratchet I99 and thus positively pre~ 40
vent further rotation of the take-up roll and
consequently the feed roll which is at all times in
driving engagement with the take-up roll. Thus
it will be impossible to withdraw toweling by
pulling on the soiled towel web because of the
locking arm I02.
.
The towel cabinet herein disclosed also includes
a stop mechanism adapted to be automatically
released, i.-e., the rotation of the feed and take
up rolls are stopped after the delivery of a length
of toweling such as by the pulling of the clean 50
towel web. Subsequently, after a suitable time
interval, the stop mechanism is automatically a"
tuated to release the rolls for further dispens
ing of a length of toweling. Such mechanism 55
is shown in Figs. 3, 6 and 10 wherein a segmental
gear Iii having a hub II 2 journaled in the side
plate member 8 is secured to the end of the shaft
35 by means of pin II 3. Thus the shaft 95 and
the segmental gear rotate together, as shown in 60
Fig. 3. A sliding bolt I I4 adapted to be translated
in the bore N5 of the gear III is held against
displacement by the pin I I6. Mounted upon the
side plate 8 and below the segmental gear III
is a suitable timing element such as a’ dash pot
IE1 having a plunger I I8 having secured thereon
an upstanding lug ||9 adapted to move against
the translatable bolt II 4 as shown in Figs. 3 and
10. The plunger H8 has an extension I2! slid~
ably carried by the guide plate I22.
Suitable
rack teeth I 23 are provided upon the extension
I 2| adapted to be engaged by the teeth of the
segmental gear III. As viewed in Figs. 2, 3 andv
10 pulling on the web of clean toweling actuates
the gear 42 of the feed roll which in turn rotates
