- To all whom it may concern.'

:Be it known that I, Gnonen KEARNEY,

i i a citizen of the United States, residing at Highland Park, county of Wayne, State of Michigan, have invented a certain new and usefull improvement in Paper-Roll Hold; ers, and ydeclare the following tobe a full,

clear,l and exact description of the same,

such as will enable others skilled in the artV to which it pertains to make and use the same, reference being. hadto the accompanying drawings, which form apart of this specification. Y V Y. Y This invention relates to paper roll holders and its object is a simple and inexpenf paper and' other similar rolls in which the paper is in a continuous length and preferably perforated at regular intervalswhereby the portion desired for vuse may be readily separated from theroll, the parts being so arranged ras to prevent the withdrawing orunwinding ofy morethan a single sheet at each actuation of the device.` In holders ordinarily in use for this purpose, itis posf sible yto unwind a greater Iportion than is required at any one interval as nol provision is made to prevent a ycontinued rotation o f the-roll after aspecified portion has 'been unwound therefronnand it` is the purpose ofthe invention hereindisclosed to over7 come such fault and to provide a device from which the roll may not be removed until the paper is entirely unwound there-z. from, and in which the working parts such as springs and the lock for the spindle, hereinafter more fully'A described, are wholly inclosed within the core or spindle upon which the roll is mounted and, thereforeyin such position as to prevent disarrangement [or displacement thereof by accident or intent.

A further object` of the invention is a de- I f vice ofthe nature stated in which rolls provided with a core of peculiar 'formation only are` adapted for use on theI device therelby limiting the device to the use with such rolls and preventing a substitution of rolls of other forms.

These and further objects and novelties of the invention arehereinafter more fully de- .portion 10 -of the shaft.

scribed claimed and shown inthe accompanying drawings in which- Figure lisa perspective view of my proved paper rollf holder. Fig. 2 is a seotional view of the paper roll and `spindle illustrating more lfully the structure thereof' '1 andmethod of vI n'ounting inthe supporting bracket. Fig; 3 -is a cross-section of the spindle on line w;w of Fig. 2. v

Similar characters refer to similar partsthroughout the drawings and specification.

' The device consists of a bracket 1 having a fixedarm- 2 and a hinged arm 3, and {iX-- edly secured to the arm=2 is a shaft 4c. On the shaft 4 is a pyramidal shaped core or j'spindle 5 having a` central bore for the shaft, the portion 6 of said bore being greater in diameter than the portion 7 thus providing a seat 8 for a thrustbearing 9 on the shaft 4. The shaft is formed with amain portion10 of greater diameter than the portion 11 upon which thethrust bearing is mounted, and the enlarged portion y10 is provided with a spiral groove 12 in which'a Vpin 13 secured to the core rides,

whereby a rotation of the core produces a longitudinal movement thereof on the-shaft vas indicated by the dotted lines a in Fig. 2. `This longitudinal movement' compresses a spring 14: on the part 11 of the shaft be tween the thrust bearing 9 and the'enlarged The thrust bearing 9 enables the core to be rotated without ra rotation of the spring on the shaft and vprevents frictiony which would otherwise oc- ,curV ifthe spring engaged a rotatingseat.

- The hingedarm -3 terminates in an en- "larged portion 15 provided with a socket 16 which the free end of the'portion 11 of vthe shaftengages, and in the portion 15 of the arm '3 is secured a pin 17 provided with a longitudinal slot 18 in which a pin 19 in the arm engages and by .,Ineansof which the pinv is held from complete withdrawal from theend of the arm.` The end of the portion l1 of the shaft is bored to receive the pin 17 and, when fully inserted within the bore in the shaft, a lock-pin 191 engages in the slotl and Jholds the pin in position. The pin 191 `is 'provided with a spring-`20 moreparticu- Patented sept. s, 1914..-

larly shown yin Fig. 3 which tends to hold the pin in place and provides a lock for holding the parts in normal position. The core 5 is provided with acut out portion 21 allowing access to the lock-pin 191 to withdraw it from engagement with the slot 18 whereupon the pin 17 maybe withdrawn from the end of the shaft as indicated in dotted lines in Fig. 2, and whereupon the hinged arm 3 may be swung to one side as indicated by `the dotted arrow in said figure. The papercore of the roll may now be rek moved from the core or spindle 5 and a new roll placed thereon, whereupon the arm and pin 17A are returned to their'normal position as shown by full lines in said figure. From the above description itfmay be seen that all loose parts such as the spring etc., as well as the locking device are entirely inclosed withsuch position that mischievously inclined persons may notv readily disarrange the parts and destroy the usefulness of the device.

The paper preferably used on this device is perforated at regular intervals of greater or less extent depending upon the purpose for whichlthe roll to be used and the longitudinal movement of the roll on the 'l' 7 plete sheets.

" 1` this invention to provide a core or spindle shaft is sufficient to allow removal of a singlesheet at each actuation thereof, the

thata sheet may be unwound from the roll fwhen the core is of' its smallest diameter and, while' a somewhat greater length may be unwound from the roll at a single actua* tion when first placed thereon, it is not so great as to allow the removal of two com- The sudden stopping of the roll in its longitudinal movementA on the shaft, tends to separate the sheet from the roll at the line of perforation.

` Fixtures of this nature are not ordinarily i sold to the consumers lbut remain the property of those supplying the paper, the intent being to secure succeeding orders from the consumer by reason of the provision of thefixture. This method of disposing of the fixtures does not always hold the paper supply business as it `1s very common for manufacturers to supply rolls of paper for use on fixtures belonging to or furnished by other supply houses and it is an object of of such shape that a roll of paper in order to Ybeused on this fixture must have a core of corresponding'shape, and rolls not as provided can not operate theV device. l have "i therefore formed the spindle 5 in the shape of a` four sided truncated pyramid and within the usual round core 22 of the paper roll, lgprovide, a paper core23 corresponding `in shape to the shape of the spindle 51 and provided with the ends 24 andl 25 which are glued in place in the paper core of the roll. With a core of this form fitting the spindle, a rotation of the roll insures a rotation of the core and consequent movement of the spindle is heretofore described, butif a roll of the ordinary round core only be placed on the spindle the axis of the roll will not coincide with the axis of the shaft but will lay at such an angle thereto that the edge of the roll will engage the sharp teeth like projection 26 on the arm 3V and, a rotation of a roll be practically prevented and therefore such roll would be .totally unadapted for use on the fixture.

'fConsequently consumers that are supplied @with fixtures having the formation herein described must necessarily seek their supply paper from the manufacturer or agency :supplying the fixture. l in the core or spindle 5 and therefore in s Having thus briefiy described my invention and its mode of operation, what I claim tand desire to secure by Letters Patent of :the United States is- 1.
