My invention relates to improvements in paper r011 dispensers, which are particularly adapted for dispensing paper towels. The object of the invention is to provide a dispenser suitable for schools, hospitals, public buildings where it is desirable that a towel strip may be projected from the roll and allowed to hang freely therefrom, so that it may be removed without the need for touching the roll. Further objects are to provide a fixture which will have a delayed action, to prevent useless extravagance of paper, and to provide a dispenser which is extremely economical to manufacture and which cannot get out of order, except through long wear or serious damage.

The invention consists of a dispenser head adapted to support a transversely perforated paper roll, which dispenser is provided with a jet for dislodging the free end of the strip wherein air is supplied to the jet from a suitable compression device and the air supply to the compression device is restricted, as will be more fully described in the following specification and shown in the accompanying drawing, in which:

Fig. 1 is a side view of the invention showing parts in section.

Fig. 2 is a plan View of the paper cabinet.

Fig. 3 is a modification of the air line connecting the bellows with the air jet.

In the drawing like characters of reference indicate corresponding parts in each figure.

The numeral l indicates the paper cabinet which consists of a back panel 2 from which side walls 3 and 4 connected together by a top wall 5 extend. The side wall 4 is divided vertically to provide a hinged panel 6 having on its inner top and forward edge a rim I, see Figure 2. The side wall 3 and the hinged panel 6 are each fitted with a matrix 8 which serve to non-rotatably support a paper roll 9, indicated by dotted line in Figure 1. The top wall 5 is provided with a hinged extension or cover ill to enclose the perforated paper roll. The cover I0 is provided with a rim II on each side edge which overlaps the front edge of the wall 3 and the panel 6.

Mounted upon the back panel 2 is a tube l2 which terminates at its upper end in a relatively fine jet l3. The disposition of the jet I3 is somewhat below the free edge line of the paper roll and is directed towards the paper roll so that the air stream emanating from the jet l3 will cause the free edge of the paper to be carried over the roll and hang downwardly where it is accessible to the user.

Below the paper dispenser l a suitable compression device or blower I6 is provided, which consists of a metal casing I 1 having a sloping cover [8 hingedly connected thereto. Within the casing l! is a rubber bag H! of substantially angular cross section as shown, which bag is provided with a nipple 20 which serves as air inlet and air outlet to and from the bag. A pipe 2| communicates between the bag and the jet l3.

In the modification shown in Figure 3 a ball valve 25 is inserted in the pipe 2|, which valve consists of a vertical sleeve 26 having a valve seat 21 at its base and a ball 28 normally resting upon the seat. The valve seat 21 is not necessarily ground and is therefore capable of allowing a slow leak of air downwards, so that the bag I9 may fill slowly. The ball valve incidentally is not necessary except in cases where an abnormal volume of air is required to be forced out of the jet l3.

In operation, as foot pressure is applied to the cover I8 the bag 19 is compressed to force a volume .of air at high velocity through the jet l3, which causes the free end of the paper strip to be thrown over and drop out between the paper roll and the front cover Ill so that it can be conveniently grasped and a connected strip be torn oil. As soon as the foot is removed from the cover [8 the bag l9 endeavours to fill and return to its normal shape and incidentally to return the cover I8 to normal position. Since the only air access to the bag is through the jet Hi the bag is slow in filling and consequently cannot immediately provide suflicient air to deliver a second paper strip even though foot pressure were applied to the cover l8 again. By providing this delayed action a considerable saving is effected in the amount of paper used.

It will be obvious that the blower It may be disposed for hand operation instead of foot operation if desired.

What I claim as my invention is:

1. A paper roll dispenser comprising a cabinet adapted to support a transversely perforated paper roll, a jet within the cabinet adapted to direct a fiow of air onto the paper roll to dislodge its free end and carry it over the paper roll, a manually operated blower device having a single opening only to serve as both inlet and outlet and a pipe communicating between the blower device and the jet, and valve means between the blower device and the jet for permitting a free flow of air from the blower to the opening and for delaying the flow of air entering through said opening into said blower device.

2. A paper roll dispenser comprising a cabinet adapted to support a transversely perforated paper roll, a jet within the cabinet adapted to direct a flow of air onto the paper roll to dislodge its free end and carry it over the paper roll, a blower device consisting of a rubber bag of sufiicient strength to maintain itself in distended form, said bag having a single air opening and a pipe connecting said opening with the jet and a plate member in contact with the bag adapted to be depressed to collapse said bag.

3. A paper roll dispenser comprising a cabinet adapted to support a transversely perforated paper roll, a jet within the cabinet adapted to direct a flow of air onto the paper roll to dislodge its free end and carry it over the paper roll, a manually operated blower device consisting of a rubber bag of sufiicient strength to maintain itself in distended form, said bag being enclosed in a container having a hinged cover and being adapted to normally support said cover in raised position, said bag having a single air opening and a pipe connecting said opening with the jet.
