Feb. 14, 1967 N. L. JONES PAPER ROLL HOLDER Filed March 16, 1965 INVENTOR NED L. JONES ATTORNEY United States Patent 3,304,034 PAPER ROLL HOLDER Ned L. Jones, 3209 Butter-field Road, Yakima, Wash. 98901 Filed Mar. 16, 1965, Ser. No. 440,182 3 Claims. (Cl. 248--27) This invention relates to a holder for paper rolls and the like.
An object of the invention is to provide a holder for paper rolls which is simplified and compact in construction, neat and attractive in appearance, and reliable and efficient in operation.
A further object is to provide a paper roll holder wherein the roll supporting tube or rod is held detachably on bracket arms by a novel spring arrangement enabling the paper roll to be inserted and removed from the holder laterally without difiiculty. The construction eliminates the sometimes awkward manipulation of spring-loaded supporting tubes of the type which must be compressed axially for mounting in a bracket structure. The present construction enables the paper roll and its supporting tube to be quickly installed laterally within recessed bracket arms containing contoured leaf springs which yield to allow easy passage thereover of the ends of the roll supporting tube and easy removal thereof, the springs serving to firmly hold the suporting tube in the installed position.
Another object is to provide a holder for paper rolls in which the retaining springs are replaceable.
Other objects and advantages of the invent-ion will be apparent during the course of the following description.
In the accompanying drawings forming a part of this application and in which like numerals are employed to designate like parts throughout the same,
FIGURE 1 is a perspective view of a paper roll holder embodying the invention;
FIGURE 2 is a vertical section on an enlarged scale taken on line 22 of FIGURE 1;
FIGURE 3 is a perspective view of a modification; and
FIGURE 4 is an enlarged fragmentary end elevation of a bracket arm, spring and associated elements.
In the drawings, wherein for the purpose of illustration are shown preferred embodiments of the invent-ion, attention is directed first to FIGURES 1 and 2, wherein the numeral designates a supporting frame adapted to be installed flush with a wall surface surrounding a recess for the paper roll. The frame 10 carries an integral arcuate forwardly open housing part 11 which enters the wall recess and serves as a lining for the recess. The housing part 11 has fiat parallel end walls 12 as indicated.
Rigidly mounted upon the vertical sides of the frame 10 and projecting forwardly thereof at right angles thereto is a pair of bracket arms 13 adapted to support a paper roll 14. The bracket arms 13 may be integral with the frame 10 or may be detachalbly rigidly secured thereto by screws 15, as found preferable. The bracket arms 13 are in laterally opposed parallel spaced relation near the vertical center of the frame 10, as shown in the drawings.
Each bracket arm 13 is channel-like in transverse cross section and comprises an outer side wall 16 and top and bottom horizontal walls or flanges 17 and 18. A forwardly open horizontal recess or socket opening 19 is formed in the inner side of each bracket arm 13 and includes a circularly curved rear end wall 20 having a radius which defines the overall vertical depth of the recess 19, which recess opens through the forward end of the bracket arm 13.
Mounted within the lower part of each bracket arm 13 immediately inwardly of the side wall 16 is a longitudinally extending contoured leaf spring 20' having an upwardly crowned intermediate portion 21 which projects con- 3,304,034 Patented Feb. 14, 1967 siderably above the lower wall 18 of the bracket arm but terminates well below the vertical center of the recess 19 and forwardly of the center for the radius which defines the curved rear end wall 20. The spring 20 further comprises a generally horizontal portion 22 contacting the lower wall 18 and a forward terminal part 23 which is reversely curved relative to the crowned portion 21. At its rear end, the spring has a depending transverse extension 24 received within a notch 25 in the end of the lower wall 18. The extension 24 is clamped firmly within the notch or recess 25 by a screw 26. The sides of the notch 25 engage the parallel edges of the spring extension 24 and prevent the latter from turning relative to the bracket arm. To further stabilize the leaf spring, there is a shallow ledge 27 formed along the outer side of the lower wall 18 and the spring engages inwardly of this ledge and between it and the outer wall 16. The crowned portion 21 of the spring projects well above the ledge 27, FIGURE 2. The construction of both [bracket arms 13 is identical, and therefore the detailed description of one arm will serve to describe both. The two arms 13 are in opposed relation with their recesses 19 facing inwardly, as shown in FIGURE 1.
The holder further comprises a tube 28 formed of sheet metal or the like and having a length slightly less than the distance between the walls 16 of the two bracket arms 13 and an outside diameter slightly less than the vertical depth of each recess 19. The supporting tube 28 is adapted to have the core tube 29 of the paper roll 14 applied thereover so that the paper roll hangs freely from the tube 28. The tube 28 has its end portions projecting beyond the ends of the paper roll, as is usual. The exposed end portions of the supporting tube 28 are adapted to be introduced laterally through the recesses 19 until the ends of the tube 28 are seated against the curved [back walls 20 of the recesses. The leaf springs 20' will yield to allow the tube. 28 to pass laterally thereover and the crowned parts 21 of the springs will hold the ends of the tube 28 snugly against the curved wall 20 and the upper wall 17 of the bracket arms 13, as clearly shown in FIGURE 2. The arrangement allows free turning of the paper roll on the supporting tube 28 at all times. The entire paper roll and the tube 28 may be pulled laterally out of the bracket arms 13 at any time and the two springs 20' will yield to permit this. The installation or replacement of the roll along with the supporting tube 28 is rendered very simple without sacrifice of security of holding by means of the leaf springs. The awkward arrangement where axially compressible spring-loaded supporting tubes are employed is completely eliminated by the invention.
FIGURE 3 shows a slight modification of the invention where the companion bracket arms 30 embodying the invention are mounted upon a supporting wall which is not recessed to receive the paper roll 31. The bracket arms 30 are therefore longer than the previously described arms 13 and are equipped with rear apertured flanges 32 to facilitate attaching them to the supporting surface. The bracket arms 30 in all other respects are identical in construction and function to the arms 13 and all other features of the invention are identical to the corresponding features shown and described in the prior embodiment of the invention. All of the advantages of the invention enumerated above in connection with the prior embodiment are also present in the embodiment shown in FIG- URE 3. The details of construction shown in FIGURE 4 are of course common to both forms of the invention.
It is to be understood that the forms of the invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size and arrangement of parts may be resorted to,
3 without departing from the spirit of the'invention or scope .of the subjoined claims. 1
