To aZZ whom it may concern.

Be known that I, WILLIAM B. COLLINS, a citizen of th in the borough of Ben Avon, in the countyof 6 Allegheny and State of Pennsylvania, have invented or discoveredthenew,"usefu1, and" Improved Roll-Pa tus, of which .the to er-Dispensing Apparalowing 1s a SPBClfiCgitlOIl,

:MyiIIVBIIiJIQn COIISlStS in new andnseful 1 improvements in means for dispensing pa per, such as paperotoweling'toilet paper,

' wrapping paper and the'like, 'in'measured' quant ties from a parent roll; "It" is much less expensiveto siich' paper up in a coi1 "-J pply ng e 1P tinuous roll as compared to same in cut and folded form, but previously dispensing such paper irom'a roll has been uneconomical, owing to the'waste Dispensing apparatus has been made for 2 this purpose in Ywhich the roll-of paper is rotated to dispense the paper-by a pull 'jeX- erted on the loose end'of the paper, and after the paper has beenunrolled 'anddetached theroll is rotated in the opposite direction to its former position. 'Meanshave "been provlded for limiting the dispensing rotaljonof the roll, and alsofor r'otati'ng the rollpinthe reverse direction. v I V 'lhedifliculty has'been that the amount or papers. delivered by. lajgiven rotation of the roll varies with'thefdiameter of the roll of paperf Thus when a fresh roll is; put in the dispensing apparatus a given" rotation .will deliver a'much longer length ofpaper than is delivered when the roll of paperis paratus by providing the same with means I controlled by theamount of paper contained in the roll for regulating the rotation ofthe roll the dispensing operation whereby substantially thie'same length of paper will United States, and residingalways be dis ensed notwithstanding pro gresslve depletionof the'paper stored on the parent roll.

the accompanying drawings wherein 1 I illustrate an apparatusembodying the;v

principles of my invention, Fig; 1' is a plan view of the same, -the apparatus being in its 1 p0s1t1on of rest; Fig. 2 is an end view look ing from the left in" Fig. 1, the apparatus being however in the posltion assumed when the'pa'per has been unwoundl'in a operation; Fig. 3 is a view similar to Fig." 2

but "illustrating a modification, the appa-w ratus' being in its position of rest, and Fig. l 1s a detail view in cross section showing the paper core of the use IV-IV in Fig. 1; Y

The followingis a detailed description the drawings;

A repr'esentsthe support which may beta board. *Brepresent's a'fixed Wall, a table or a stand at one 'side and C'the usual "hinged stand at the other *sideofthe support: 1) represents the axial spindle having one end fixed in the 'sta'nd' B while'its other end is detachably secured to'the'st and C in such a dispensing i parent roll mounted on the spindle of the machineylt aken along the manner as to hold said stand in its erect "or extended position. ThustI have'shd'w'n the spindle D provided with at spring finger 1 p which snaps into'engagement with a hook on thecylindrical boss 2 of theihi'nged stand G. The particular structure so far described forms no part of my present invention, and any other convenient manner" of supporting thespindle in such awaythat the parent roll'may be slipped thereonmay lee-adopted.

w Eis the metal mandrel upon-which the roll of paper is mounted. Thus the mandrel may be a tubewith'a non-circular or flat.- tened-perimetral' surface, or it may be an open frame; One end 'of' the mandrel E, the left end'in 1, is provided'witha circular end late*3,and :near'the other end of said man rel is provided the 'filler plate 4. 'The plates 3 and i' are axially perforated so that the mandrel B may he slid on to' the spindle the plates 3, and j ournaled on the'spindle.

the filler 4 being the outer surface of the end plate 3 is the spur-gear F, the same being positioned in; sidethe stand'B. Meshing with said spur "gear is'a toothed .quadrant G whose hub is journaled eccentrically of the parent roll a 1 a sta 'Fixed axially to wei t ifiee e of the stand B near the bottom thereof. Thus, when the mandrel E is rota-ted the quadrant G is swung on its axis.

I-I represents the paper in the form of, a continuous roll wound about a paste-board or other core tube I of the; proper internal form to slip easily over the mandrel E when the stand G is swung down to PIOVidQgCiGQT" ance. Thus the parent roll H, the mandrel E and, the. pinion F will rotate in unison and their rotation. will swing, the quadrant G. In the drawings the rotation of the parent. roll Hain dispensing the paper is assumed: to be clockwise, and thus, the un-,

winding of the paper from the parent roll will swing the quadrant G counterclockwise.

I provide means for returningthe roll to its: former position aften the, pull on the paper hasceased? and the unwound paper is;

detached; ThusI may provide a spring 6 connecting the proper end, of the quadrant A meansmay be provided for accomplishing the return rotation of the roll. In Figs. 1 and Q-the patent rollnisshowninrthe position which: it assumed when the predetermined amount of paper has been, unwound and before it has been returned intov its original position. In Fig; 3' the roll isshown in the position itassumes after-having been rotated in: the reverse direction.

The quadrant Gispnovided with a finger J which extends parallel with the axis of the paper roll, and. which swings with the qu ad rant as the latter moves: counterclockwise as the paper is. unwound from. the parent roll, until said finger comes in contact with: the perimeter of theirol'l as indicated in. Fig. 2. It is evident thatthe, contact of the finger J with the parent roll-v will halt the ro tationof the quadrant and thus halt the rotation of the-parent roll. thereby limiting the amount of paper which is; unwound from said parent roll. It is also evident that; as the parent roll diminishes; in diameter the finger J will move farther in a counterclockwise direction, in: the dispensing operation thus. permittinga greater notation of the parent roll. By this means I am able to compensate for thediminution of the parent, roll, and by properly proportioning the parts,and the ratio of the pinion to the quadrant, so regulate the rotation of a, parent roll so that substantially the same amount of paper will always be delivered at an operation, notwithstanding the variations of the diameter of the parent roll due to. the removal of paper theretrom.

If it be desired to use a roll of unperforated paper any convenient form of cutting mechanism may be provided, a number of which are well known in the art, but if paper transversely perforated at regular intervals is used my dispensing machine will deliver the perforations at the proper place for detachment at each operation of the apparatus.

It is evident from the foregoing that paper toweling, toilet paper, wrapping paper and the like may be convenientl and; eco-. nomically dispensed by" my device from: a parentv roll, a substantially uniform length of paper being delivered for detachmentat each operationof the. appanatus, thereby i nut ng uni rm y-'i the he ts or lengths:
