PAPER-ROLL, RACK.

To all lwhom z't may concer/nf 'l Be it known that we, FREDRICK WINTER- HALTEn-and FREDRI'CK T. VIN'riclznAL'inn,

citizens of the nited States, and residents of Bayonne, in the .county'of Hudson and 'State of New Jersey, have invented a new and Improved Paper-Roll Rack, of which the following is a full, clear, and exact de- Another object of the invention is to provide a paper-roll rack having feeding rollers whereby anydesired quantity of paper may be fed fromthe' rack without pulling on the `endl extending in front or ahead of the cutter.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention `consistsin the novel construction, combination and arrangement' of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming lpart of the application, similar characters 4 of reference indicate 'corresponding parts in both views.

Figure 1 is a perspective view of the paper-roll rackl embodying our invention; and

Fig. 2 is a verticalr cross section therethrough. l

The racks -commonl y employed for dispensing wrapping paper hide the edge of paper beyond the edge ofthe cutter after a section of the paper has been severed,v and to get hold of the'edge to pull on the paper to dispense it from the roll it is necessary to manipulate the roll to force the paper edge ahead of t-he cutter.' The paper edge often being ragged resists the vmovement and causes the paper coming from the roll to buckle until the buckling force overcomesthe resistance, when the ragged edge jumps gast the cutter and cuils about the roll. This rings the edge 0f the paper into a very inconvenient place for grlpping and time is 10st... If the roller is turned to bring the Specification of Letters Patent.

edge into a convenient position, it happens very'often that the ragged edge passes inwardly beyond the cutter and it is necessar to raise the cutter and thread the'paper,.a l'

of whichcauses delay and loss of time.

To obviatethe above defects we have pr'ovided a cutter which has a lini'ited' movement and which is displaceable by the pull.

exerted on the paper when the same is fed otl' the roll, means being provided for 're storing the cutter. to its initial position and means for preventing the paper from returning \\'hen the cutter is returned, so that a portion of the paper from the roller always extends in front of the cutter, present innVV a gripping portion.

efcrring to the drawings, 3 is a base of any suitable material, preferably rectangu lar in form. A standard 4- is mounted at4 each end of the base. Each of the standards presents a bearing 5 for the axle 6 0f a core 7 which carries a roll of paper 8. A block 9 is secured to each of the standards to engage frictiona'lly. the core 7 and thereby pre-- vent a tooY easy rolling of the papel` roll on 'its bearings. Each of thestandards has a rising rearwardly extending arm 10 which terminates in a curved bifurcated portion 11.

A pair of feed rollers 12 have the axles 13 thereof engaged in the bifurcated portions 11.

The two rollers are maintained in contact by y gravity.

A' shield llll extends from the axle 13 of.4

the lower ialler l2 over the paper roll 8.

Its movement on the axle toward the roll under the action of gravityis' 'limited by arms 15 which engage the bifurcated .'portionsll of the arms 10. A paper guide 16 is mounted to oscillate over the shield t0- and from the feed rollers 12, the axis of oscillation being the axis ofthe paper roll 8.

The paper 17 from between the feed rollers 12 passes over the guide 16. It is retained upon the guides by. a retaining member 18 which is free to swing under the action of gravity on the axle 13 of the'upper feed roller Y12. 'This retainer will prevent the Ipaper from moving with'the guide when the guide returns to its initial position under.

the action of counterweights 19 extending from the bearings ofthe paper guide 16 tol ward the base 3. mally tend to move the paper 'guide toward the feed rollers 12,the movement bei ng limited by bumpers 20 which come in contact with ob- The counterweights norstructions formed in the base S-for said bumpers.` It will benoted that the counterweights are veryclose to the vertical plane passing l guide from the rollers. When the pull is released the weights are at about an angle of 45 with the vertical plane above referred to and, therefore, at maximum eiliciency, thereby quickly bringing the guide -to its initial or normal position. i 'l A cutter2l is provided abovethe guide 16 slightly rearward of the front, upwardly curved edge and secured to participate in the movement of the guide. Preferably sufficient clearance is provided between the guide 'and the cutterv to facilitate an easy threading of the paper between the two. A The cutter 21 preferably forms a art of a shield orA `cover 22 which extends albove the guide and'houses the retainer 18. Normally a portion of the paper protrudes between the cutter and the guide, hanging over the guide so as to present an overhanging Iportion which can, be easily. gripped'- by the fingers. In pulling on the paper the guide is moved therewith until its movement is 'resisted by the engagement of the bumper with the obstruction on the base, which determines the oscillation of the guide. In continuing the pulling, paper is drawn between the 'cutter p and the guide until the desired amount of paper has been drawn through.' By afswift movement the paper can be severed at the ,cutter 21, particularly if the paper is, narnow. In case of papers of great width, a

Afinger is placed on to the shield 22 and the paper can then be severed by a slow movement In the first case, as soon as the paper has been severed gravity will restore the paper guide and, therefore, the cutter to the initial position, the return movement of the paper being prevented by the retainer 18 and, in consequence, a portion of the paper will overhangthe front end of the guide ready to be gripped. In the second ease` as soon as the hold on the shield is released gravity will restore it to the initial position, leaving a portion of the paper protruding in the manner as stated.

The feed rollers 12.prevent a too rapid feed of paper when pull is exerted on the paper or when Ipaper is drawn off the roll. They furthenprevent. the sagging of the paper. between the guide and the roll. If by inadvertence the edge of the paper is beyond the cutter, it is only necessary to revolve the upper feed roller 12 in the directionally-operable aaeaeea tion of the arrow shown lin Fig.v 2, which would feed the paper past the cutter-in the -position and, therefore, prevents an accidental buckling of the paper between the guide and theiollers 'when the guideis restored to its initial position. This member 14 also prevents the vplacingof too large av roll of paper upon the standards. It will be noted that the. guide and shield associated therewith are removable from the axle of the roller which protrudes through the standards 4, and that neither the retainer nor the paper support will interferewith the removal; the counterweightsas well as the bumpers being outside ofthe standards and diverging, in no way interferewith tlie removal of the guide.. The feed rollers can be easily removed from the bifurcated portions 11 and therewith the member 14 and the retainer to admit a new paper roll intoy the standards.

While we have described the principle of operation, together with the device lwhich we now consider to be the best embodiment thereof, we desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the appended claims.
