(Cl. 312——53)
This invention relates to a mechanism for dis
pensing paper towels of the inter-folded type
wherein the pulling out of one towel pulls the
end of the next towel into an accessible position.
The invention includes features, some of which
are applicable for the dispensing of other kinds
or types of paper toweling.
The preferred embodiment of the invention
shown herein includes means for preventing
quick successive operations of the feeding mech
anism, thus making it necessary for the user to
wait for some predetermined time period before
he can obtain a second towel. By this means, the
number of towels used is substantially reduced
and great economic gain is made.
Features of the invention include: the down
feed and delivery of the towels for access from
the bottom of the cabinet: the incorporation of
friction-reducing means in the towel supply sup
port; the arrangement of the feed-roll-separat
ing and stop mechanism; and. the details of con
struction of the same and the broader ideas of
means inherent in the disclosure.
Objects, features and advantages of the inven
25 tion will be set forth in the description of the
drawings forming a part of this application, and
‘in said drawings:
Figure 1 is a front sectional elevation view
ing the mechanism as when the door is removed

tioned as in Figure 5;
Figure 2 is a vertical transverse section on line
2-2 of Figure 1;
Figure 3 is a view similar to Figure 2 with the
35 mechanism positioned as after a feeding opera
tion, and with a towel so positioned as to be ac
cessible to the user, and with the timer and stop
mechanism positioned as in Figure 4;
Figure 4 is a vertical transverse section on line
40 4-4 of Figure 1, showing the timer stop mecha
nism positioned as immediately after towel de
livery and withdrawal;
Figure 5 shows in full lines the timing and
stop mechanism positioned as at the end of the
45 timing period, and shows, in dot-and-dash lines,
the position of the stop arm and timer control
link as during the feeding operation;
Figure 6 is a plan section on line 6-6 of Figure
l, with the parts positioned as in Figure 4;
Figure '7 is a vertical section on .line 'l-'l of
Figure 6 showing the means acting promptly
after feeding to prevent reverse motion of the
feeding means; and
just before the pawl assumes the position of Fig
ure '7;
The drawings show the, at present, preferred
embodiment of the invention, but the invention
is not entirely limited to the details shown.
In the drawings, numeral I indicates the cas
ing or cabinet which has a door 2 hinged at its
bottom, as at 3, to the bottom of the casing. A
suitable lock is shown at 4. Within the cabinet
are arranged two plates respectively indicated 10
Ill-4i, said plates being spaced from the end
walls of the cabinet and being suitably secured
as at I2--i3 to the walls of the cabinet. The
back wall I4 has inverted keyhole slots I5 adapt- .
ed. to be engaged with hooks on the wall to sup- 15
port the cabinet.
The towel supply chamber is de?ned by the
plates Ill—-i I, the rear wall It, the door 2 and a
pair of plates, see Figures 2 and 6, the mem
bers of which are respectively generally indicated
at l8-l9. These plates form the bottomof the 20
towel supply chamber, and the pile of towels is
supported upon them. Each plate has a ?at por
tion 20 provided with a plurality of transverse,
spaced, relatively narrow, upwardly bulging por
tions ‘ii. The plate is bent downwardly as at
22, then upwardly curved as at 23 and then is
bent to provide a horizontal portion 24, spaced
below the portion 23. The plate is then bent
upon itself to provide a smooth rounded portion 80
25, is then arched outwardly as at 26, and ends
in a relatively flat, inwardly directed portion 21,
the lower longitudinal edge of which is slightly
spaced from the periphery of one of the feed rolls.
These plates have down-turned ?anges which are 35
suitably secured to the plates Ill and H by means
generally indicated at 3|].
The plates l8 and I9 are substantially identi
cal in ?guration but are arranged as rights and
lefts, with their portions 25 and 2'! spaced to pro- 40
vide a downwardly leading throat delivering to
the feed rolls. The bottom-most sheets of the
supply of paper rest on the apices of the ele
ments 2| and 23, and have, so to speak, a bridg
ing relation with these elements. Inasmuch as 45
there are only line contacts between the elements
2| and 23 and the paper, withdrawal friction is
reduced to the minimum. For clearness, the
lowermost sheets have been di?erentiated by
making one solid black, de?ning others by two 50
lines only, and others by two lines, plus stip

A feature of the invention is the downward de
livery of the sheets to a point outside of and be
low the cabinet for access by the user. The
throat-forming plates are held by suitable fasten
ing means to the plates II and II and, of course,
extend from one plate to the other.
An important feature of the invention is the
construction of the combined stop and feed roll
control mechanism now to be described. Refer
ring ?rst to Figures 6, '7 and 8: The shaft 33 is
provided at opposite ends with arms respectively
designated 0 and 44 adapted to engage the shaft
80 of the roll I! and'move it in the slots away
from the friction surface 4! of the roll II, and to
turned in the direction of the arrow because the
stop arm immediately engages the part ‘II. At
the end of the timing period, the off-set portion
10 of the connection is brought into opposition to
the part 50 so that the latter is free to make a
complete revolution in counter—clockwise direc
tion from the position shown in Figure 5, again
to that position thus permitting a feeding oper
ation, which is accomplished herein by a single
rotation of the shaft 33. During this operation,
the roll 32 moves to feeding position, is operated 35
for feeding and is moved again to its spaced non
feeding position.

of the shaft by means of the crank 35 in counter
non-feeding position. Each arm 43 and 44,
therefore, has in its periphery a depression or
notch ll, see Figure 8, adapted to receive the shaft
45 35, as shown in Figures 4, 5, 6 and 7. The shaft
85 is urged toward the roll II by means of springs,
one at each end of the shaft, and attached as at
“to the plates ll and II. One arm of each
spring engages a stop ll, and the other arm passes
through an opening in a clip 50 circumscribing
the shaft 85. The spring, of course, is coiled, as
shown in Figure 6, at Ii and tends to press the
shaft 35 toward the roll ii. The clip 50 is slotted
as at 52, so that the arms 43 and 44 can directly
engage the ends of shaft ll.
Referring to Figure '1: In order to prevent re
verse rotation of the rolls at the end of each feed
ing operation, a pawl 55 is provided and is ar
ranged as shown in Figures 7 and 8, and pivoted
at 55 to the plate II. In Figure 7, the pawl is
positioned to prevent rotation of the arm 43 in a
direction opposite to that of the arrow. In Fig
ure 8, the pawl is being pushed by the arm to a
position from which‘ it will swing to the position
of Figure 7. Figure 7 shows the separated non
feeding position of the rolls, and Figure 8 shows
the rolls in feeding position but just about to be
moved from feeding position as the arm 43 swings
to bring its notch 40 in releasably locked engage
70 ment with the shaft 36. Each arm “44 has
a cam surface II which leads to the depression
or notch 45 and gradually pushes the shaft It
outwardly to its non-feeding position.
The arrangement of a stop arm, now to be
described, on the shaft II, adjacent one of the
clockwise direction, as viewed in Figure 5, the‘arm
5. is moved and the link 5! is drawn upwardly
correspondingly moving the connection ll up
wardly. The full upward movement of the con 45
nection to set the timer is made at about the end
of a half revolution of the shaft 33, that is when
the parts assume the dot-and-dash line position
shown in Figure 5. On completion of the feeding
rotation of the shaft to-the position shown_in
Figure 4, the link assumes the position shown in
that ?gure and the timer is thus free to act and
move downwardly merely swinging the link in
clockwise direction. with the parts positioned as 55
in Figure 4, the shaft cannot be turned because of
the relation of the stop 50 to the part ‘II of the
connection 55. At the end of, the timing period,
however, as shown in Figure 5, the stop arm is
free to rotate because the o?-set portion ‘II is
opposed to it. On slight initial movement of the
shaft a from the position in Figure 5, the arms
l3, 44 move to release the roll 32, which immedi
ately moves to feeding position so that feeding
occurs while the shaft 33 continues its motion.
It will, of course, be understood that each time a
towel is moved to position for acc‘essaby the user,
it pulls the end of the next towel between the
rolls in position to be fed at the next operation
of the machine.
There is no intention to be entirely limited to
the use of any particular number of feed rolls,
nor'indeed to the use of rolls at all, because other
modes of feeding might be employed. I believe
