ROLL HOLDER Filed 001:. 1, 1946 Patented Nov. 7, 1950 UNITED STATES PATENT OFFICE ROLL HOLDER Amos H. Ramquist, Vashon, Wash.

Application October 1, 1946;Serial No. 700,552

Claims. (01. 242-5512) This invention relates'to holders of the type used for supporting rolls of web-like material such as cloth, paper or cord and is more particularly concerned with a holder of the foregoing type in which the roll of paper, cord or cloth is supported for freerotation during use, but is restrained against axial displacement beyond a predetermined range. Materials'such as paper towels, toilettissue, cloth, etc., that find frequent use in'the homeand in industry are sold in roll form; the web of material being wound around a hollow central support or cop. In use, it is customary to support the-wound roll for rotation about'an-internal member over which the hollow cop or tube of the roll freely fits. In use, sheets or lengths ofthe material are withdrawn from the roll by'pulling thefree end and tearing or cutting off the length required, unwinding of the roll resulting in rotation thereof about the support.

The art relating to-supports for rolls of weblike material is highly developed, and-many different types of roll holders are-presently available. Most of these'are-characterized by a central support andflanges at either end which prevent the roll from sliding'axially oil of the support. since the rolls have to be replaced from time to time after they have become depleted'of material, the roll holder assembly 'isusually comprised of detachable parts so that'the end caps or thelike may be removed to-permit replacement of a roll over the central support. Quick detachable connections between the ends or caps of a roll holder and the cylindrical supporting portion thereof have been-the subject of considerable studyand numerous-patents have been granted with respect to such connections. 1 Despite this activity, however, prior arrangements usually involve a connection that is released by pressure somewhere on the cylindrical supporting portion of the holder which is not conveniently accessible when .a roll change is required. Furthermore, prior. art roll holders in general are characterized by a rather-largenumber of parts which renders their constructionsomewhat expensive and their operationsubject to mechanical failures.

.It is therefore an objectof'this invention to provide-a roll holder consisting of but two parts which is characterizedlby-a conveniently operable quick detachable connectionbetween an end cap and a cylindrical roll supporting portion, and which. is simplein: design so that construction is inexpensive and operation is free of mechanical failures.

Other objects andvadvantages of this invention will be apparent upon consideration of the following detailed description of several embodiments thereofin conjunction with the annexed drawings wherein:

Figure l is aperspective view of a roll holder constructed in accordance with the present invention showing the end cap in detached position;

Figure 2"is a longitudinal sectional view of the holder of Figure 1;

Figure 3 is a view in side elevation of the holder of Figure '1 showing the cap in assembled or roll restraining position;

Figure 4 is a view in longitudinal section of a modified type of roll holder constructed in accordance withthe'present invention; and,

Figure 5 is asimilar view of another modified form of roll holder also constructed in accordance with the present invention.

Referring now in greater detail to Figures 1, 2 and'3 of .the drawings, the roll holder there illustrate'dis comprised of a central cylindrical portion 10 adapted to-receive thereover the hollow tube or cop about which a roll of web or cord like material is wound. At one end of the cylindrical portion Ill is provided with an integral flange ll of sufficient diameter to block the roll against movement oil" of the cylindrical portion atthatend thereof. The flange II is provided with a plurality of holes at [2 for the reception of screws or the like for mounting the rollholder so-that the flange may perform the dual function of restraining the roll against movement ofi'of'the-cylindrical portion at that end thereof, and may support the cylindrical portion incantilever fashion from a wall surface or the like.

Now'upon reference to Figure 2, it can be seen thatthe cylindrical portion [0 may be made of molded plastic or cast metal which is-solid for a substantial portion of its length extending fromthelftend of Figure 2. The right hand end of the cylindrical portion as shown in Figure 2, is provided with a number of slots I3 which exten'dlongitudinally inwardly from the end of the cylindrical portion remote from the flange II, the slots communicating with a frusto conical cavity l4 extending inwardly from the slotted end of a-cylindrical portion to a point slightly beyon'd'themid'dle thereof. The slotted end of the cylindrical portion isprovided with an annular, externalrim l5 which is adapted to be received-in'an annular groove H5 in a cavity or socket in anend cap 11. Thegroove I6 is complementary to-the'riml-l: and is of slightly lesser diameter than' the external diameter of the rim.

Ahead of the groove l6, and partially defining it, is an internal rim l8 at the mouth of the socket in the cap ll.

It can now be seen that in normal roll supporting position, Figure 3, the cap ll and the flange ll restrain the roll supported on the cylindrical portion it! against axial movement oil of either end thereof. However, since slots I3 afford a certain resiliency to the slotted end of the cylindrical portion it, it is evident thatthe rim I is continuously biased into firm engagement with the portions of the surface of the cap l? which define the groove 16, thus insuring the holding of the cap in position. When a roll replacement is necessary, it is only required that the cap ll be pulled axially to the right, as viewed in Figure 3, to cause the rim 1% of the cap to wedge the rim l 5 of the cylindrical portion to a sufliciently small cross section so that the cap may be removed. The resiliency of the material. immediately restores therim to its normal unrestrained position as shown in Figures 1 and 2; With the cap removed the roll may he slid over the rim l5 and on to the cylindrical portion ll Thereafter, the cap is moved axially to the left, as viewed in'Figure 2, causing the rim to compress the rim 55 which then expands again into the groove 86 to hold the cap in position.

The construction shown in Figure 4v is similar to that described in connectionwith the Figures 1 to 3 inclusive except that the cylindrical por-- tion I9 is made of sheet metal which is blanked, pierced, rolled and curled to produce a rim 2i! and then attached to a flange 2| by cleated tabs 22. The cap 23 is made of two parts, 24 and 25, joined together at the margins. Once constructed the device of Figure 4 consists of but two parts, the assembly including the cylindrical portion and the flange, and the cap assembly. As described in Figures 1, 2 and 3, the rim 28' coacts with the cap 23 in the same way that therim [5 coacts with the cap l1.

Referring now to Figure 5, there is shown a roll holder comprised of a solid integral cylindrical portion 26 having an integralrigid rim 2'! at one end and an integral flange 28 at the other end. This assembly may be made of porcelain, pot metal, aluminum, brass, plastic or wood. It is intended that. the flange Zl coact, with a cap 29 provided with an internal rimifl and an internal groove 3i. In the previous embodiments described, the rim on the cylindrical portion is indicated as resilient. In the present case, the internal rim of the cap 29 is made of rubber or as a spring ring so that the rim 3!.) rather than the rim 2'! is resiliently held in a normal position and is compressible in a radial sense to permit detaching and attaching of the cap. 1 K

= .It will be understood that the embodiments de-' scribed do not constitute all of the forms in which the present invention may be constructed, but are merely illustrative-of the nature and principles of the present invention, the scope of which is defined in the appended claims.
