It is the object of the presentv invention to
and servicing, comprises what may best be
providev paper supporting and feeding means for
termed an inner housing and a cover member
a towel dispensing cabinet which will insure
proper feeding of an. uncrumpled and untorn
length of toweling upon each dispensing operation of the cabinet, and which will insure against
jamming or clogging of the paper within the cabinetA further object of the invention is. the provision of a dispensing device in which the-operating mechanism and the most vital parts of the
paper feeding mechanism. are protected against
tam'pering or adjustments by unauthorized persons, even-when the dispenser is opened- for the
purpose of replenishing the towel supply therein.
A still further object is the provision of paper
feeding mechanism which advances a length of
toweling to. a. position where it may be torn from
a continuous roll upon each dispensing operation
of the cabinet, and to prevent tearing of. the
paper within the cabinet at any point which is
likely to cause the paper to become jammed or
‘crumpled or torn during. the. next dispensing op-
therefor. The inner housing consists of a back
plate H! (see Fig. '7) which may be secured
against a wall by any conventional means, and‘
a bottom plate I I, preferably formed integrally
with and extending forwardly from. the. lower
edge of the back plate. Secured to the back and
bottom plates are side plates [3' and; [4 (see also
Fig. 1), which side plates. are set inwardly a short
distance from. the outer edges of the back‘and
bottom plates and provided with'outwardly pro
j‘ecting ?anges I5 which extend all of the way'
around the side plates so that the side walls of
the housing are in fact recessed. from their outer
sides to provide spaces Within which may be dis
posed‘ substantially all‘ of the mechanism by
means of‘ which the toweling is dispensed,
Each of the recessed outer sides of the side
plates [3 and I4 is preferably covered‘ by inward
1y ?anged cover plates I6 and I Go, respectively,

plates and form enclosures for the towel dispens
eration.

The arrangement of. the dispenser and pres

cabinet are all disclosed in my copending appli

‘ of which the present application is a continua
tion in part.
It has been found in practice that upon feed
ing a strip or web of paper between rolls such
as those described, there is often a tendency for
means to secure the bearing; discsv in place.
The pressure roller 58 is also‘ mounted in re
placeable bearings which permit of its easy assem
bly and removal, and which are combined with
resilient means for urging it; into contact with
the dispensing roller 56. The construction of
these bearings- is illustrated in Figs. 2, 7 and‘ 8,
wherein the roller is shown as: provided with.

its absorbent qualities, becomes compressed or
lengthened at the point of greatest pressure be

rapidly at some points than it is at others. In
