PAPER-REEL.

Specification of Letters Patent.

7 Patented June 6, 1916.

Application filed January 3, 1916. Serial No. 69,884.

Tr. all whom 2'25 may concern Be it known that I, FRANK H. Honnnc, a citizen of the United States of America, residing at Green Bay, in the county of Brown and State of lVisconsin, have invented certain new and useful Improvements in Paper- Reels, of which the following is a specification, reference being had therein to the accompanying drawing.

The invention relates to reels and its principal object consists in the provision of a reel which upon manipulation may be rotated to describe two complete revolutions whereupon it is arrested and after severing the paper the reel is automatically brought into original position by describing two revolutions in the opposite direction.

Another object of the invention is to provide means for preventing the withdrawal of a paper roll slid upon the reel in the longitudinal direction making it necessary to cut the core of the paper roll longitudinally after the paper has been completely unwound.

To the accomplishment of the general objects stated and others which will more fully appear the preferred embodiment of the in vention consists in the construction and arrangement of parts to be described, illustrated in the accompanying drawings and defined in the appended claims.

In said drawings, Figure 1 is a front View of the reel mounted in a bracket, the reel being in its normal position. Fig. 2 is a front view with part of the reel and shaft in section. Fig. 3 is a fragmentary view of the reel when in normal position showing the stop arm in contact with the side bar of the reel adjacent a slot therein. Fig. 4 is a similar view as Fig. 3, but showing a slot in the side bar in alinelnent with the stop arm as occurs when the reel has completed one revolution. Fig. 5 is a view showing an advanced position of the slot relative to the stop arm which occurs when the reel has described two complete revolutions. Fig. 6 is a fragmentary view of the reel with the roll of paper in section thereon. Fig. 7 is a perspective view of a catch plate adapted to lock the paper roll 1n place.

In the drawings 1 designates a suitable bracket having apertures 20 for purposes of attachment to a wall, door, or the like.

2 denotes in general the reel which comprises a plurality of disks 3, 4, 5 with central openings and interconnected at their periphery by side bars 6 to form a rigid reel structure. The reel 2 is rotatably mounted on shafts 7, 8 which extend through the central openings of the disks and cooperate with the reel in a manner to bepresently described. One end of the shaft 8 is enlarged and provided with screw threads 9 and enters with a square tongue 10 a similarly shaped opening in the bracket arm 13 whereby the shaft 8 is secured against rotation. The opposite end of this shaft is hollow to receive the adjacent end of the shaft 7 which abuts a. spring 11 disposed therein. The opposite end 12 of the shaft 7 is journaled in an aperture in the appertaining bracket arm 13. This disk 5 of the reel 2 has screw threaded engagement with the screw threaded end 9 of the shaft 8. A stop arm 14 is keyed to the shaft 8 and extends far enough to engage the upper edge of the bar 6 adjacent a notch 15 provided therein. A coil spring 16 surrounding the shaft 8 is secured with one end thereto while its other end forces the bar 6 of the reel 2 into engagement with the said stop arm 14. The rotatable shaft 7 carries a plate 17 formed with an upturned pointed projection 18 adapted to enter the core of the paper roll and to prevent the same from being withdrawnfrom the reel in longitudinal direction.

The reel is actuated in the following manner: To remove the reel structure it is only necessary to shift the shaft 7 longitudinally against the spring 11 until the end 12 thereof clears the bracket arm 13. A. roll of paper wound ordinarily on a center core of card board is then slid onto the reel until the core enters into engagement with a shoulder 19 of the end disk 5. The projection 18 of the catch plate 17 possesses suflicient flexibility to permit shifting of the paper roll in one direction, but prevents a longitudinal movement thereof in the opposite direction, since then the point 18 enters the core of the paper roll. When paper is withdrawn the roll of paper revolves simultaneously with the reel structure upon the shafts 7 and 8. The stationary shaft 8 bepermitted. Upon completion of the second revolution the slot 15 has traveled farther toward the left hand side so that the stop arm 1% engages the under side of the side bar (3 and prevents further rotation of the reel structure. After a sheet of paper has been torn off along the line of perforations the roll is released and the spring 16 will untension and cause the reel to describe two revolutions in the opposite direction to return the same to its original position.

It is obvious that various changes and alterations may be made without departing from the spirit and scope of the invention, and I want to avail myself of all such departures within the scope of the appended claims.

I claim:

1. A paper reel comprising in combination with a bracket having suitable arms, shafts in axial alinement mounted. in said arms, a reel structure rotatably mounted on said shafts, a stop arm secured to one of said shafts, and means for bringing said reel structure in engagement with said stop arm upon completion of a predetermined number of revolutions in both directions.

2. A paper reel comprising in combination with a bracket having suitable arms, shafts in axial alinement mounted in said arms, one of said shafts being rotatable, the other of said shafts being stationary, a stop arm secured to said stationary shaft, a reel structure rotatably supported by said shafts, and

means for bringing said reel structure in engagement with the stop arm upon. completion of a predetermined number of revolutions in both directions.

3. A paper reel comprising in combination. with a bracket having suitable arms, shafts in axial alinement mounted in said arms, a stop arm secured to one of said shafts, a reel structure rotatably supported by said shafts, and means for shifting said reel structure longitudinally and into engagement with said stop arm upon completion of two revolutions in both directions.

4. A paper reel comprising in combina- -tion with a bracket having suitable arms,

shafts in axial alinement mounted in said arms, one of said shafts being held against rotation, a reel structure comprising a plurality of disks and bars interconnecting the same, a stop arm secured to said non rotatable shaft, means for shifting said reel longitudinally and into engagement with said stop arm upon completion of a predetermined number of revolutions in one direction, and means for automatically restoring said. reel to original position. upon release.

5. A paper reel comprising in combination with a bracket having suitable arms, shafts in axial alinement mounted in said arms, one of said shafts being held against rotation, a reel structure comprising a plurality of disks and bars interconnecting the same, a stop arm. secured to said non-rotatable shaft, means for shifting said reel longitudinally and into engagement with said stop arm upon completion of two revolutions in one direction, and resilient means for automatically restoring said reel to original position upon release. I

6. A paper reel comprising in combination with a bracket, shafts in axial alinement mounted in said bracket, one of said shafts being locked against rotation, a stoparm secured to said statlonary shaft, a reel structure comprising a plurality of disks and bars interconnecting the same, one of said bars being provided with a slot adjacent said stop arm, one of said disks having screw threaded engagement with the stationary shaft whereby said reel structure is shifted longitudinally and is permitted to describe two revolutions upon manipulation, and means for automatically restoring the reel structure to original position upon release.

' 7. A paper reel comprising in combination with a bracket, shafts in axial. alinement mounted. in said bracket, one of said shafts being locked against rotation, a stop arm secured to said stationary shaft, a reel structure comprising a plurality of disks and bars connecting said disks, one of said bars being recessed adjacent said stop arm, one of said disks having screw threaded en gagement with said stationary shaft whereby the reel structure is shifted longitudinally and is permitted to describe a predetermined number of complete revolutions upon manipulation, and a spring between said stationary shaft and said reel structure to re turn the latter to original position upon re lease.

8. A paper reel comprising in combination with a bracket, shafts in axial alinement mounted in said bracket, a stop arm secured to one of said shafts, a reel structure ro-tatably supported by said shafts, means for shifting said reel structure into engagement with said stop arm upon completion of a predetermined number of revolutions in both directions, a catch plate mounted upon one of said shafts and having portions engaging said reel structure, said catch plate provided with a single flexible pointed projection adapted to permit the paper to be slid upon. the reel structure and to automatically expand and enter the inner side of the paper upon shifting the same in opposite direction.

In testimony whereof I hereunto affix my signature.
