United States Patent This invention relates to new and useful improvements in stands for rolling sheet material.

One object of the invention is to provide an improved stand having a reel for rolling sheet material thereon to facilitate handling, packaging and shipping of the material.

Another object of the invention is to provide an improved stand, of the character described, wherein the reel is of such construction that sheet material may be readily wound thereon and removed in roll form therefrom, which'material may be relatively thin, light-weight and diflicult to handle, such as sheet plastic.

A further object ofthe invention is to provide an improved stand, of the character described, wherein the reel includes novel clamp means adapted to be readily engaged with and disengaged from sheet material where by the material may be easily and quickly connected to and wound on said reel and removed therefrom.

A construction designed to carry out the invention will be hereinafter described, together with other features of the invention.

The inventionwill be more readily understood from a reading of the following specification and by reference to the accompanying drawing, wherein an example of the invention is shown, and wherein:

Pig. 1 is a perspective view of a stand constructed in accordance with the invention,

Fig. 2 is an enlarged, perspective view of an upper portion of the reel of the stand, its clamp and latch,

Fig. 3 is a top plan view of the stand with the clamp lower portion of the stand.

In the drawing, the numeralltl designates an upright stand embodying the principles of theinvention and including a flat, horizontal base 11' which is preferably circular. An axial, upstanding pin or spindle 12 is carried by the base for supporting an upright reel 13 by its longitudinal, tubular axle or mandrel 14 (Fig. 4). Preferably, a suitable bearing 15 is interposed between the base 11 and the tubular axle 14 to facilitate rotation of the reel 13 relative to said base and its spindle 12. The reel is substantially cylindrical and is adapted to support sheet material M (Fig. 3) which is wound on said reel to facilitate handling thereof. Usually, the material is relatively thin, light-weight and diflicult to handle, such as sheet plastic. After the desired length of material has been rolled or wound on the reel, it is adapted to be removed in roll form by sliding the same upwardly oif of said reel.

The reel 13 includes a plurality of substantially annular or circular, circumferential bands or rings 16 connected in substantially parallel, spaced relationship by One of the bands 16 is provided at each end of the reel and the bars 17 are substantially coextensive with said reel. Substantially radial arms or members 18 are provided for Patented Feb. 24, 1559 connecting the circumferential bands to the tubular axle 14.- For imparting rotational movement. to the reel, a

crank 19 is. provided at the upper end of said reel and includes an arm 20 telescopingly mounted in a complementary housing 21 (Figs. 1-3). Suitable supporting legs 22 depend from the housing 21 for connection with the closed upper end 23 of the shaft 14 and one of the radial arms 18. The crank housing terminates inwardly of the exterior of the reel and the arm 20 is of such length to permit telescoping thereof inwardly of said reel exterior, whereby the telescoped crank does not interfere with the upward removal of rolled sheet material from the reel.

As shown most clearly in Figs. 2 and 3, each annular or circumferential band 16 is interrupted to provide an opening 24 between its ends and one end, preferably the clockwise end, is offset inwardly of the other end.

The openings 24 are vertically alined and coact to pro-' less length than the other memberKFig. 3).

For confining one end of the sheet material in the reel opening, a clamp 26 is mounted in the openings 24 for engagement with .the clockwise ends of the bands 16. The clamp includes an elongated, actuating element or rod 27 extending longitudinallyof the reel and having a handle 28 on its upper end. Suitable bearing members oi-plates 29 extend between the inner portions of the. arms 25 for rotatably supporting the actuating rod 27 adjacent the axle 14. A plurality of transverse clamp arms or members 30 are connected to the rod by suitable collars 31 immediately below the plates 29 whereby the clamp arms extend outwardly between the pairs of reel arms 25. A longitudinal clamp bar or member 32 is secured to the outer ends of the arms 30 for overlying engagement with the outer portions of the bands 16. adjacent their clockwise ends. As shown in Fig. 3, the clockwise ends of the bands are engaged by the outer end portions of the clamp arms and the inward offsetting oflsaid band ends provides space for accommodating the clamp bar 32 whereby said clamp bar is disposed within the circular contour of the reel. By swinging the handle 28, the actuating rod 27 is rotated for swinging the clamp 26 into and out of engagement with the clockwise ends of the circumferential bands 16.

In order to hold the clamp in such engagement, a latch 33 is provided and includes a rock shaft 34 having a handle 35 at one end. .A pair of apertured lugs or cars 36 project upwardly from the arms 25 at the upper end of the reel 13 to rotatably support the shaft 34 in overlying, transverse relation to said arms and the clamp arm 30 therebetween. The intermediate portion of the shaft has a wedge-shaped dog or element 37 projecting laterally therefrom for engagement with the uppermost clamp arm 30 andjthe counter-clockwise reel arm 25 so as to hold the clamp 26 engaged with the clockwise ends of the bands 16 to confine one end of the sheet material M therebetween as shown in Fig. 3, whereby said material is attached to the reel for rolling thereon.

In order to facilitate rolling of the material on the reel, a guide 38 encircles the lower portion of said reel in concentric, spaced relationship. The guide 38 includes a plurality of upright posts or rods 39 mounted on the base 11 and having their upper ends connected by a substantially annular band or ring 40. Preferably, the guide surrounds at least the lower half of the reel.

a. The ends of the bandarespacedfrom each other, with.

one end being welded or otherwise secured to one of the posts 39 and its other end being connected to an adjacent, elongated. post or rod41. which, is substan: A substantially, coexs tially coextensive with thereel. tensive angle bar or member-42 is carried by the clone gated post-41 tozprovide a. straight edge and. fiat surface which facilitates cutting or severing of the sheet ma,-. terial As has been explained, the sheet material M is rolled onto the reel 13. until the desired length is obtained.

When the latch 33, is disengaged. as shown in Fig. 2, the

clamp 26 may be swung out of. engagement with: the clockwise ends of thebands 16 to permit the insertion of .the, free end of the material therebetween. Upon reengagement of the clamp and latch, the. materialis con:-
