Description

Feb. 419, 1935 E. A. LA ROCK 1,992,077
PAPER ROLL HOLDER Filed Feb. 24, 1954 Patented Feb. 19, 1935 UNITED STATES PATENT OFFICE 2 Claims.
The present invention relates to means for supporting paper roll webs and has for its object the provision of a support of simple construction which will firmly hold the web of paper in position for use and permit free rotation of the roll while preventing endwise movement of the same upon the shaft. The invention is illustrated in the accompanying drawing and will be hereinafter first fully described and then more particularly defined in the appended claims.
In the drawing,
Figure 1 is a vertical section of so much of a paper roll support as is necessary to an understanding of the present invention. I
Figure 2 is a transverse section on the line 2--2 of Figure 1.
In the drawing the reference numeral 1 indicates a portion of the usual rigid supporting frame which may be of any known or approved construction and is shown as having a notched lug 2 providing a seat for one end of the shaft 3. The shaft 3 is provided near each end with an annular rib or enlargement 4, as clearly shown;
The usual tapered plug 5 is employed to be inserted in the end of the central opening provided in the roll of paper and has the usual longitudinal circular opening 16 therethrough to receive the end of the shaft. In the present instance,
however, an annular groove '7 is formed in the wall of the opening 6 to accommodate the rib 4, as clearly shown. The diameter of the opening 6 is slightly greater than the external diameter of the rib 4 so that the plug may be easily slipped over the shaft and the rib. After the roll is in proper position upon the shaft, the weight of the roll will cause the plugs to drop onto the shaft with the groove 7 engaging over the rib 4,
a as willbe understood upon reference to the drawing. The roll will thus be supported by the shaft so that it may be easily rotated about the same, but endwise movement thereof will be prevented by engagement of the rib and groove in an obvious manner.
The device is exceedingly simple so that it is not apt to get out of order and will not entail any expensive operations to produce any of the parts and while the parts will remain in properly assembled relation as long as the web of paper is in place they may be very easily disassembled to permit the insertion of the plugs into a new roll and then easily assembled with the shaft. No springs or other relatively movable elements are employed in the device so that breakages and frequent repairs are obviated.
Having thus described the invention, I claim:
1. A paper roll support comprising a shaft having an annular rib adjacent its end, and a tapered plug insertable in the end of a roll and having an axial opening therethrough to receive the shaft, and an annular groove in the wall of said opening to engage the rib on the shaft.
2. A paper roll support comprising a shaft having an annular rib near its end, and a tapered plug insertable in the end of a paper roll and having an axial bore of a diameter to receive the shaft and the rib thereon and having an annular groove in over said rib whereby the plug may rotate on the shaft but is held against relative endwise movement.
