ROLL PAPER FIXTURE 5 Filed Oct. 24, 1932 FIG 4.- 1724- .1 INVENTOR WIIAfESS S I X46?- "/"II WM d T 'FORNEY Patented Mar. 20, 1934 UNITED STATES PATENT OFFICE ROLL PAPER FIXTURE Wisconsin Application October 24, 1932, Serial No. 639,224

3 Claims.

The invention relates to fixtures for dispensing sheets from rolls of paper or the like, such as wax paper, and has for an object the provision of a durable but inexpensive roll-supporting fixl ture adapted for household use and having a cutting member including a cutting portion extending along the roll and releasably held in operative position with respect to the roll, the cutting member being readily displaceable from its operative position to facilitate replacement of the roll.

The invention further consists in the several features hereinafter described and claimed.

In the accompanying drawing;

Fig. 1 is a top plan view of a roll paper fixture embodying the invention;

Fig. 2 is a transverse sectional view of the fixture taken along the line 22 of Fig. 1;

Fig. 3 is a front elevation of one end of the fixture;

Fig. 4 is a fragmentary sectional view taken along the line 4-4 of Fig. 2, and

Fig. 5 is a fragmentary rear view of one end of the fixture, parts being broken away and parts being shown in section.

In this drawing, designates a rectangular base member having marginal flanges 11 which are adapted to engage a support 12, here shown to be a vertical wall. The base member 10 is preferably a sheet metal stamping and is secured to the support 12 by screws 13 which pass through openings 14.

The base member 10 has formed therein near each end a pair of parallel guide slots 16 slidably receiving therethrough the spaced legs of a U-shaped sheet metal strap or stirrup 17, the free ends of the legs projecting forwardly from the base member. A pair of sheet metal rollsupporting arms or brackets 18 have end portions 40 interposed between the spaced legs of the respective straps 17, and each has inturned side flanges 19 which engage embossments 20 formed on the strap legs and which are pivotally connected thereto by rivets 21. Near the rivets 21, the flanges 19 have their edges fulcrumed on ribs 23 embossed on the base member 10 between the slots 16 and the adjacent end edges of the base member.

Each strap or stirrup 17 is urged inwardly by an arched leaf spring 24 which has an intermediate portion bearing on the inner face of the base member and reduced end portions or tongues 25 slidably fitting in openings 26 formed in the strap, thus retaining the spring in place. By this means the arms or brackets 18 are springurged toward each other about their pivotal bearing on the ribs 23.

The above described spring mounting of the arms .or brackets is disclosed in the application of Samuel N. Hope and Nicholas Tuszynski for Roll towel fixtures, Serial No.'621,361, filed July 8, 1932.

At their free end portions the arms or brackets 18 are provided with rounded embossments'27 which are adapted to enter the opposite hollow ends of a roll 28 of sheet material to be dispensed, such as wax paper, the roll being rotatably mounted on these embossments; In the present instance, the roll is shown to be provided with a tubular core 29 of paper or other suitable ma- 7!} terial. An annular shoulder 30 surrounding each embossment 27 is engageable with the end of the roll and is here shown to engage the end of the core. The shoulder 30 is urged against the end of the roll by the action of the spring 24 to frictionally retard the rotation of the roll. In the present instance the embossment 27 and shoulder 30 are formed on a sheet metal cup 2'7 which has a flaring edge 30 fitting within the outer end of the arm 18 and secured thereto by an inturned marginal bead-forming flange 18' on the arm. With this construction the embossments 2'7 on the cups may be economically formed in various sizes.

An embossed sheet metal cutting frame 32, 35 formed from a rectangular loop-shaped blank, is pivotally mounted at its rear bar near the lower edge of the base member 10 about an axis parallel to the roll 28, spaced ears 33 being struck up from the base member and pivotally connected to cars 34 bent up from the cutting frame, as by a rod 35 or other suitable means. The cutting frame includes resilient hook-shaped side bars 36 which at their outer ends extend partially around the rounded outer ends of the brackets 18, the side bars 36 being retained by their spring tension against the brackets. The side bars 36 are suitably ribbed to provide the desired degree of resiliency. At their forward free ends the side bars 36 are integrally connected by an outwardly offset longitudinally ribbed cutting bar 37 of arcuate cross-section extending parallel to the roll and having a lower serrated cutting edge 38 spaced from the outer surface of the roll. The upper rear edge of the cutting bar has an intermediate recess 39 to facilitate manual rotation of the roll. The cutting frame 32 can be sprung off the roll-supporting brackets 18 and dropped away from the brackets to the dotted line position shown in Fig. 2, the downward movement ets. The embossments 27 of the spring-urged brackets are then permitted to enter the opposite ends of the roll core. The cutting frame 32 is then swung upwardly and sprung unto the outer ends of the brackets 18. V

When the fixture is in use, a length of waxed paper is drawn from the roll 28 through the space between the side bars 36 and is cut off by lifting it against the serrated cutting edge 38. The roll isprevented from turning too freely by the frictional engagement of the brackets 18 with the roll. The resilient mounting of the arms 18 permits the roll to be properly accommodated on the fixture notwithstanding variations in roll width met with in manufacture. When the roll is exhausted, the core can be easily removed from the fixture and another roll mounted in place, as above described.

The fixture is constructed of relatively few parts which are principallysheet metal stampings, thereby permitting economical manufacture.

What we claim as new and desire Letters Patent is: 1. A fixture for paper rolls and the like, comto secure by prising a support having spaced roll-carrying" brackets for receiving a rotatable roll therebetween, and a cutting member swingably mounted on said support and having a cutting portion extending along the roll, said cutting member having resilient hooked side bars connected to said cutting portion and adapted to be releasably sprung over and embrace the outer ends of said brackets for retaining said cutting portion along the roll. 7 l i 2. A fixture for paper rolls and the like, comprising asupport having spaced brackets for rotatably carrying a roll therebetween, and a sheet metal cutting frame having a pivotal mounting on said support spaced from the roll axis to be swung thereon into and out of operative position with respect to the roll, said cutting frame having a cutting portion for disposition along the roll and having resilient hooked side portions at opposite ends of said cutting portion to be sprung over and into latching engagement with the out- I er ends of said brackets when said frame is swung about its pivotal mountin gto its operative posi- 7 tion.

3. A cutting device for a fixture rotatably supporting a paper'roll or the like, comprising a res'lient sheet metal frame having a cutting bar and resilient side bars'integral therewith, the portions of said side bars adjacent'said cutting bar being reversely hooked to form a resilient latch ing means, and the portion of said frame distant from said cutting bar having a pivotal mounting.
