stick out while a second roll of paper was in a non-dispensing position within the housing and the roll holder assembly rotates to reverse the roll holder position relative to the housing, when the first paper roll is used up and to bring the second or reserve roll into the delivery position.

Dispensers of the general type described here are used in industry and institutes and are usually checked once or twice a day to replace the used rolls. In this way, the staff checks the various dispensing devices in predetermined periods of time, replaces used rolls and brings opened rolls back into the correct position. One of the obvious benefits of using delivery devices that are able to sequentially deliver a variety of paper rolls, is that more than a single roll paper is provided at each location so that the review werii _fc) 3r often needs to happen unn there is always enough paper available.

These inspection intervals are of course determined to wet the initially given roll is completely used in most dispensing equipment and the reserve roll "is just ixi consumption. With the discussed '"rühsreii Ao ^ -ibgerätijn, indifferent oo of the kind with

This pawl spring 80 has a free lower end 82 which is resiliently urged transversely away from the right side wall 32 of the housing and this movement away from the plate is by engagement of an integral end portion 84 of the lower end 82 of the spring in a transverse recess 86 of the transversely protruding pawl stop 88 which is provided on the right side plate j2 . A generally hook-shaped cross-section, open to the front and angled downward to the rear, guide 90 is formed on the right side plate 32 and protrudes transversely from this plate adjacent to the pawl spring 80 and the pawl stop 88, as best shown in Fig. 2, J5 4 and 4, the entirety of the pawl spring 80, the pawl stop 88 and the guide 90 have the purpose of controlling the movement of the roller holder assembly 24 within the housing 22, just like the previously described running rails 56 and 38 in the housing rare plates and the housing inversion preventing pawl 72, the function of which will be described below.

As in the housing 22 in Figures 1 to 7 and separately therefrom in fl. 8-10, the roll holder assembly 24 has one U-shaped metal bracket 92 which has essentially identical roll holders 94 and 96 at the ends. The roll holder 94 and 96 are supported by the bracket 92 in the longitudinal direction parallel and at a longitudinal distance through a right roll holder frame 9Θ, so that grooved bracket end

parts 100 and 102 actually represent the left ends of the roll holder, while the roller holder frame actually constituting the right ends of the roll holder "Thus, the grooved Bügelendteile form 100 and 102 are left protruding parts for the roll holders 94 and 96 and the protruded portions 104 and IO6 of the roller holder frame 98 form right protruding parts for the mentioned reel seat, which all protrude transversely.

Each of the roll holders 94 and 96 has a cylindrical one Mandrel 108 with a thickened part 110 and a thinner part 112, and a longitudinally rotatable sleeve 114 having a pair of forward and rearward spaced and aligned pawl engagement legs 116. The roll holder tubes I08 are pushed over transverse bracket parts 118, with the thinner parts 112 of the mandrel are attached to the roll holder frame 98 and said roll holder frame lies along a longitudinally aligned bracket part 120. Furthermore, the thorns 108 held axially on the cross bracket parts 118 by holders 122, which are in grooves 124 and spring washers abutting them Γ26 engage, which in turn rest axially on parts of the mandrels IO8.

The roll holder sleeves 114 are slid axially over the thinner portions 112 of the mandrel and rotatably engage the

set forwards and backwards protruding, essentially triangular stabilizers 1 ^ 2, which are arranged in the longitudinal direction identically in relation to the corresponding roller holders ^ k and 96 , as can be seen particularly well in FIG. In addition, in the roll holder group 94, the roll holders 94 and 96 and the roll holder frame 98 can be made of molded plastic, while the bracket 92, as already mentioned above, is preferably made of metal.

Rolls of paper, generally labeled 1 ^ 4, and to be dispensed from dispenser 20 according to the present invention have slotted cores 136, as best shown in Figures 5 and 6, where these slotted cores in axially aligned. Ratio be maintained by I38 paper that is wound on the reels is. It can also be seen from Fig. 5 that the slots in the cores axially between the enlarged Parts 110 of the mandrel and the sleeves 114 of the reel seat 94 and 96 are made to ensure that this works properly of the dispenser 20 is required, as will be described below.

When using the dispenser 20 according to the invention, the roll holder group 24 is separated with paper rolls 1 ^ 4 filled from housing 22, said paper rolls being pushed axially over roll holders 94 and 96

are with the slotted cores Ijj6 above the mentioned Roll holders and held by them. As previously described, if the paper is 1 ^ 3 over the slotted Cores ljjo of paper rolls Ij54 is wound, these slotted cores hold together and hold the thickened portions 110 of the mandrel and the sleeve 114 of the Reel seat 94 and 96 axially with the sleeve pawl engagement legs 116, which Iieg3n over the longitudinally downwardly directed ends IjJO of the reel holder frame 98 and are longitudinally aligned therewith. Furthermore, and during the application of the paper rolls 1 ^ 4 to the Roll holders 94 and 96 become the roll holder sleeves 114 axially aligned rather than pivoted relative to the thickened portions 110 of the mandrel by the roll holder springs 128 so that the paper rolls are simply pushed over the roll holders 94 and 96 can.

Now the filled roll holder group 24 is ready to be inserted into the housing 22, which is done by simply the housing cover J4 opened and the roll holder group is inserted with one end or the other first into the housing rails 56 and 58, the protruding roll holder or bracket end parts 100 and 102 in the narrower running rail 56 and the protruding Roll holder parts 104 and I06 are accommodated in the wider running rail 58. While the roll holder group

downwards into the housing 22 along the running rails 56 and 58 slides, pushes the front of the pawl engagement legs II6 on the sleeve 114 at the front end of the roll holder, about the roll holder 96, across which the pawl spring 80 down and comes to rest on the pawl stop 88, as shown and in the position according to FIG. 1, 2, 4 and 5 · Simultaneously and when the special latch engagement leg 116 of the roll holder 96 in engagement with the left-hand stop 88 comes, the longitudinally downwardly directed end I30 of the roller holder group 24 slides behind the Housing guide 90 and ensures correct Q-O alignment the roller holder group 24 with the housing 22.

It should also be noted that when the roller holder assembly 24 is within the housing 22 along the slide rails 56 and 58 passed downwards and the roll holders 94 and enter the straight parts of the said rails, the left protruding parts of the roll holder, as in 5, i.e. the grooved temple end portions 100 and 100 102, transversely within the housing rail 56 through the Front edge 68 on the left trough leg 56 of the housing be taken, which lays forward into the grooved temple end parts 100 and 102. The metal housing trough 26 accordingly prevents any possibility of transverse expansion of the plastic side plates j50 and j52 and makes the formation of the housing slide rails 56 and

58 with the relatively complicated arrangement of it in the plastic side plates 30 and 32 possible. In this way secure the more economically manufactured Plastic side panels 30 and 32 of the housing 22 the correct functioning of the overall construction and also create the aesthetically pleasing exterior that is possible with these side panels 30 and 32.

When the roll holder group 24 is received in the housing 22 is and brought into such a position, as described, the housing cover 3 ^ can be closed and the dispenser 20 is ready to deliver the first roll of paper 134. The first or bottom roll of paper 134 is located in the delivery position while the second or topmost Roll of paper 134 is in reserve or undelivered position is as clearly shown in Figs. If the housing cover 34 is still closed, will the anti-reverse pawl 72 disengaged from the protruding edge 76 of the lid so that the pawl rotates, to lay sioh against the edge of the housing 78 and over the topmost of the roll holder frame stabilizers I32 of roll holder group 24, as best shown in phantom Lines shown in Fig. 2. Any attempt at the role holder group 24 upwardly in housing 22 is therefore achieved by engaging the anti-reverse pawl 72 blocked on the roll holder group stabilizer I32.

If the first or lowest paper roll is in the delivery position and the second or uppermost paper roll \ y \ in the reserve or non-delivery position, as described, the first paper roll can be used in the usual way and, if the rolled up paper is completely used, I38 the slotted cores I36 completely exposed or exposed, and the housing pawl spring 80, which abuts transversely against the housing pawl engagement leg 116 which engages the housing pawl stop 88, overcomes the lesser resilient force of the reel seat spring 128 of the reel seat 96 and thereby rotates the reel seat sleeve 114 in relation to the Roller holder mandrel I08 in the manner shown in dashed lines in FIG. The turning of the sleeve 114 of the roll holder 96 by the housing pawl spring 80 pushes the case pawl engagement leg II6 transversely from the housing pawl stop and releases the roll holder assembly 24 for further downward movement along the housing rails 56 and. In the particular embodiment of the dispensing device 20, as shown here, this downward movement of the roll holder group 24 is carried out solely by gravity, as it is exerted by the weight of the roll holder group and the rest of the roll P-.pier Ij54 on it.

The downward movement of the roll holder group ? A along the

Housing rails 56 and 58 continues until the different of the lowermost protruding parts of the reel seat, i.e. the temple end part 102 and the protruding Part 106, the closed lower ends 62 and 66 of the running rail reach. Such readjustment of the roll holder group 24 brings the lowermost roll holder 96 into an exhausted position and the roll holder 94 in a delivery position, the remaining paper roll 134 under the lower edge of the housing cover jj4 exposed, ready to use the coiled one Paper 1 ^ 3 as clearly shown in Figs. While the Rollerihaltergruppe 24 is in this lowest position moved downward, the forward one of the pawl engaging legs 116 engages the reel seat sleeve 114 of the reel seat 94 into the housing inversion prevention pawl 72 and swings this pawl counterclockwise, as in Pig. jj seen until the said reel holder Qi walked down through the anti-reverse pawl is at what point in time this anti-reverse pawl clockwise only by gravity rotated back to engage the housing edge 78 and over the front of the pawl engagement legs 116 on the Roll holder 94 to lie, whereby the entire roll holder group 24 against upward movement along the Running rails 56 and 58 is blocked and the holding of the unused paper roll l> 'i in the delivery position described secures.

At a certain time during the use of the top paper roll 134 on the roll holder 94, the maintenance time for the dispensing device 20 comes and the maintenance personnel only unlocks the housing cover 34 and opens it and tilts the cover into the open position. Tilting the housing cover 34 ^to the open position causes the protruding edge j6 of the cover to engage the protruding portion 74 on the inversion prevention pawl 72 and bring this inversion prevention pawl 72 into the counterclockwise position as seen in FIG Roll holder group 24 is no longer blocked against upward movement along the housing rails ^{56 and l jQ.} The entire unitary roll holder assembly 24 can therefore be slid up and out of the housing 22 to be serviced removed from the housing.

At this time, the roll holder group is in the state that it has a partially used roll of paper 134 on the upper roll holder 94 and one completely used paper roll, i.e. only the slotted cores I36, on the lower roll holder 96. The maintenance process is carried out by only the Roll holder assembly 24 is turned around its ends, the slotted Cores I36 are removed from the roll holder 96 and a new paper roll 134 is pushed onto it. the

Roll holder assembly 24 is then put back into housing 22
inserted with the roll holder 94 in the lower position containing the partially used paper roll 134, while the roll holder 96 in the upper position contains a completely new roll of paper 134.

Since the roll holder 94 contains the partially used roll of paper I34 so that a certain amount of wrapped paper I38 holds the slotted cores I36 of the roll together, the roll holder 94 is in the previously described latched state for engagement with the housing latch stop 88, as well as in the mold as previously described. The roll holder 9 ^ is therefore now in a
Dispensing position, and the roll holder 96 is placed in the inverted, non-dispensing position. When the partially used paper roll 134 on the roll holder 94 is completely used up, the unlatching and downward movement of the roll holder group 24 is repeated to bring the now lower roll holder 94 into the empty position and the now upper roll holder 96 into the delivery position.

A dispenser as described above is advantageous in that it provides a variety of dispensers of paper rolls of the type described, wherein the roll holder group to the unitary sliding movement is mounted by running rails that are attached to the side walls of the
