9 Claims. (Cl. 24255.3}`

This invention relates generally to cabinet constructkmV for holding rolls of paper wherein paper may be readily dispensed'rom a rollY and to means associated with the cabinet for holding an auxiliary or reserve supply of paperV rolls.

A primary object of this invention is to provide provements in paper roll dispensers wherein whiie theexi pendedroll of paper may be easily re; roved'romtue cabinet, at the same time means is provid-ed whereby the mechanism is temporarily urged during dispensing operation to a position wherein a newly placed roll -rnay not be accidently displaced or removed from the cabinet.

Another object of this invention is to provideY improve` ments in paper roll dispensing cabinets wherein a supply'j of roll paper is held in reserve above the normal supply,V means being provided for holding the reserve supplyl in" elevated position until such time as it is needed. Y

These, together with other objects and advantages which will become subsequently apparent reside. in theV details of construction and operation as more fully here-` inafter described and claimed, reference being had to the,`

accompanying drawings forming a part hereof, whereinV like numerals refer to like parts throughout, and in which:

Figure l` is a vertical section taken through the improved dispenser;

Figure 2. is ahorizontal section taken substantially along the plane of section line 2-2 of Figure l;

Figure 3 is a vertical section taken substantially along` the plane of section line 3 3 of Figure l;

Figure 4 is an enlarged vertical section taken substan.

tially along the plane of section line 4 4 of Figure l;

Figure 5 is an enlarged sectional` View showingv the in Figure 6 for illustrating a modified link structure; and` Figure 8 is a transverse sectional View taken substantially upon the plane of section line S-Sin Figure 7.

Referring now more particularlytto the drawings, and at this point most specically to Figures 1 3, the reier-V ence numerall indicates the cabinet construction generally which will be seen to consist of aV front wall 1,2, a rear wall 14, ya removable cover member 16 and opposite side wall members 18 and Ztl. The entire assemblage may be removably secured to a suitable support member such as a wall 22 by means of fasteners 24 which exten through the rear Wall 14 inthe manner shown most clearly in Figure 1.

It is to be noted that the front and rear edges at the lower ends of the side walls 18 and 2i? are cutaway as at 26 and 28 to permit ready access to a roll of paper 30, disposed between the lower ends of these side wallsV in themanner shown. The paper rolls are of entirely comentional construction and consist of inner rolls or cores 32 upon which the paper isA wound and ay spindlev 36 which projects through the core 52.`v and extends on opposite sides thereof Vfor the purpose of rotatably supporting the paper rolls;

The manner in which the paper rolls are supported in the cabinet structurel() will be seen most clearly from' a study of the Figures 1'-3 wherein it is to be 'noted' that a horizontal support arm 38 is pivotally secured intermedi#v ate its ends to. each of the side walls 1'81and' 2li. as byV pivot pin member 4,0'. These' supportV arm members arel grooved. or notched as atr42 to receive the opposite end. portions of the spindle 36 such that the paper rolls Vare; rotatably supported` in the proper manner.

"I-Thus;` the inner ends ofthe actuator arm l17* provide asupport on which the uppermost; rolloi: paper is placed.

At its outer end,`the actuator rod or shaft 47 isprovided with a pull button frsecured thereto asv by nut members" e6 andthe inner end portion of the outerend of the'shaft is provided with a stub/ collarv 68.: to limit? its inward slidingmotion with respect to the track members 6th A coil spring surrounds-the shaft *betweenV .they front iwall l2"- and the tracl'asY 6l) and bears againstv aY collar member rigid withthe shaft such that when the shaftv is retracted; the spring 70 will be loaded to normallyret'urr thes'h'aftf to the position shown inFigure l`. AS1 previously mentioned, the upper end of the links 44 are provided with` plunger mechanisms which are illustrated most-clearly' in Figure-'5i The uppermost' ends ofY the links* 44 are threaded as at 73 and engaged thereon are thel thimble members in which'thev pistons $2' of the plunger rods 84' are slidable.

pivots 4tltin the position shwn in Figure 1. However, when the roll of paper on the spindle has been depleted;

Disposed belowy the piston"` 852 and the upperend of the links is a compression springS;` Theplunger is provided at its upper end with an enlarged headV and the spindle has been removed from the support arms 38, the support arms will be overbalanced by the weight of the links and associated mechanisms such that the lnner-ends 91 of the arms Vwill swing upwardly to engage the lower beveled end 92 ofthe rearmost track Vor kguide member 62. Simultaneously, this movement of the-supportarms will have'retracted the enlarged 'headS' from the notches 90 in the actuator shafts 4.7', perrnitting the handle 64 to be grasped so as VtoV retract or withdraw the actuator shafts. The purpose of this construction is such as to preclude accidental disengagement of the spindle 36 of the next paper roll which is automatically dropped as the actuator shafts 47 are retracted, that is, the rearmost end of the arms 38'are normally disposed with respect to the lower ends or" the track members 62 such that a spindle may be disengaged therefrom by moving it rearwardly. However, when the rearward ends of the arms are outwardly swung, insufficient space is left to permit the spindle`36 from being disengaged.

The spring 86 does, however, act as a shock absorber as the uppermost roll of paper is dropped thereon. To further aid in absorbing the shock as the uppermost roll of paper is dropped, a yoke 100 is provided. This yoke is secured at its lower end to the links 44 and extends upwardly around on opposite sides of the shafts 47 for connection to a rod 102 which projects into the cylinder member 104 and has secured at its uppermost end a resilient piston assembly 106 in a manner shown most clearly in Figure 4. The upper end of the cylinder 104 Y is provided with a bleed passage 108 and a screw valve 110 associated therewith such as to guide the rapidity with which the piston 106 may be moved upwardly in the cylinder. The cylinder is held by a colla1 or sleeve 112 and an associated set screw 114 for initially adjusting the position of the cylinder.

VReferring now more particularly to Figures 6-8 wherein the modified form of the invention is shown, it will be seen that the cabinet 120 in this case'is recessed into the wall structure 122, it being appreciated that the cabinet may be disposed flush therewith as desired. The cabinet 120 consists of a front wall 124, a rear wall 126, a bottom wall 128, a top wall 130 with the lower portion of the front wall being open and the side walls notched away v as at 132 to permit access to the roll and with the top portion of the front wall being open and having associated therewith a hinged cover member 134 in the manner Shown. The cover may be provided with a knob 136 which is rotatable and has attached to its inner end a lateral projecting latch member 138 so that rotation of the knob will effect latching of the cover or door member.

Like the modification shown in Figure 1, the cabinet assembly 120 is provided with

guide members

140 and 142, the former of which is angularly oiset as at 144 such that a paper roll may be disposed thereon in the manner shown in dotted lines.

V'The actuator shaft 146, the support arms 148 and the links 150 with the exception that the yoke members 100 previously described and their associated cylinder and piston assemblies are omitted, are identical to those previously described.

In the case of the modiiications shown in Figures 6-8, the shock absorber assemblage incorporates a star wheel mechanism indicated generally by the reference character 160.

The shock absorber mechanism consists of a pair of star wheel members mounted on a common shaft 162 and connected together by any suitable means such as a plurality of rods 164 extending therebetween which form abutment means against which a spring 166 engages. 'Ihe spring 166 is of cantilever construction and is intended to resist the rotation of the star wheel assemblage, it being noted that one finger or point 168V of the star Wheels are always projected between the track members 140and 142 such as to catch the spindle ends of the paperY roll as it is dropped duringV the dispensing operation. f

abutting engagement with the lower notched iirst portion of the actuator shafts. Each

link portion

170 and 172 has a

collar

174 or 176 rigidly attached thereto and one of the collars has rigidly secured in depending fashion thereto a plurality of plunger or rod members 178 which slidably project through the other collar member in the manner illustrated most clearly in Figure .7. 'I'he adjacent ends of the

shaft portions

170 and 172 are disposed in spaced relation and a coil spring 180 is disposed between the two

collars

174 and 176 to normally maintain in the spaced apart relation shown.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
