PAPER-ROLL. RACK.

Specification of Letters Patent.

Patented Apr. 1, 1919.

To all whom it may concern:

Be it known that we, FREDRIGK WINTER- HALTER and FREDRICK T. WINTERHALTER, citizens of the United States, residin at Bayonne, in the county of Hudson and .tate of New Jersey, have invented a new and Improved Paper-Roll Rack, ofwhich the following is a full, clear, and exact description.

Our invention relates to paper-roll racks used for dispensing wrapping paper for merchandise. This rack forms an improve ment over our rack covered by Patent No. 1,261,668 issued April 2, 1918, andit is characterized from. the structure of the patented rack by the provision of a catch for automatically locking the paper guidein the depressed position when drawing paper off the paper roll and for automatically restoring the paper guide t0-its initial position when the drawn-out paper has been severed.

An object of the invention is to provide a simple, strong and efficient paper-roll rack which will always present a portion of the paper from the roll ahead ofthe cutting knife, thus obviating the necessity formanipulating the roll of paper when paper is to be drawn from the roll.

Another object of the invention is to provide a rack of the class described having locking means for the paper guide operable by the cutting member.

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

In the accompanying drawings, forming part of the application, similar charcters of reference indicate corresponding parts in all the views.

Figure 1 is aside elevation of the rack embodying our invention, certain parts of the same being broken out to show the details of construction, the rack being shown in inoperative position;

Fig. 2 is a section on line 22, Fig. 3, the rack being shown in operative position, that is, the paper guide being shown in depressed position when a portion of the paper extended from the guide is to be severed; and

Fig. 3 is a top plan view on the rack as 1t appears in Fig. 1, certain parts being broken out to show the details of construction.

shafts are mounted to revolve.

Referring to the drawings, 4 is a frame of suitable material in which a shaft or As shown, two shafts 5 are provided and the inner ends of said shafts are supported by an arm 6 which is adjustable longitudinally in the frame 4 so that shafts 5 of different lengths may be accommodated in the frame. Each shaft carries a paper roll 7 The outer end of each shaft is provided with a friction member 8 engaged by a brake 9 the friction of which may be varied by the member 10. It is self-evident that if only one roll is used then the arm 6 is not necessary. On the other hand, if more than two rolls are used, then there will be more arms for the purpose.

The frame 4: carries a pair of friction rollers 11 each formed of independent rolling members 12 revolubly mounted on the shafts 13 of the rollers. The paper 14: from the roll passes between the feed rollers and on to an arcuated paper guide 15 which extends through the entire length of the frame and is supported above the roll by arms 16 which have bifurcations 17 straddling the proximate ends of the shafts 5. In consequence the paper guide is mounted to oscillate in the axis of the paper rolls. The guide 15 has trunnions 18 at the bifurcations which form a pivot for the arms 19 of a knife 20 extending alongside the front edge of the guide and spaced therefrom so that the. paper could be easily threaded between the guide and knife. The swinging movement of the knife 20 is limited by projections 21 and 22 provided on the guide 15 and lying in the path of one of the arms 19. The same arm carries a 111g 23 for operating a catch 24.

The catchhas a hook 25 pivotally connected to the frame 41:, so that gravity normally tends to bring the hook into the path of the projections 22. The movement of the hook under gravity is limited by a stop 26. The part of the hook 27 lying in the path of the projection 22 is rounded so that the hook is moved on its pivot 28 against the force of gravity to allow the projection'22 to enter the hook. The lateral displacement of the hook 25 is prevented by a guide 29. The catch 24: also carries a spring-actuated plunger 30 the end of which comes across the hook opening and, therefore, the same must gaged or disenagegd from the hook. In other words, the hook with the plunger forms a snap hook. i

By pulling on the edge of the paper lt lying in front of the knife 20, the guide 15 is drawn toward the front end of the frame against the resistance of the counterweights 31 which are attached to the extension of the bifurcations l7 and normally tend to restore the guide to the inoperative position, as shown in Fig. 1. As the guide approaches the catch, the projection 22 depresses the plunger 30 and engages the hook 25, the knife 20 being maintained against the projection 21 by the paper which is being pulled on. After the projection 22 has been engaged into the catch any amount of paper can be fed off the roll, as the further displacement of the guide is prevented by the catch and the knife cannot operate the catch unless the paper supporting the knife is severed to allow the knife to drop. When the desired amount of paper is severed on the knife 20, the same will. be free to drop under gravity, bringing the lug 23 against the plunger 30 thereby disengaging the projection 22 from the hook 25 under the action of the weights 31.

To prevent the paper on the guide 15 from returning with the guide, a retainer 32 is provided above the guide to engage the paper under the weight of the retainer,

which is pivotally connected to the shaft 13 of the upper friction rollers 11. To prevent the buckling of the paper by the return of the guide 15, I provide a paper support 33 in proximity to the friction rollers.

To facilitate the gripping of the severed edge of the paper on the roll, I provide an apron 34- which is pivotally connected to the front edge of the guide 15. A crank 35 constrained to revolve with the apron is connected to a push rod 36 which is guided by the guard and, therefore, carried therewith. The push rod comes against the lower friction roller 11 when the guide 15 is in the inoperative position to force the apron 34 at substantially right angles to the proximate edge of the guide. This position of the apron forces the paper upwardly and, therefore, facilitates the gripping of same when the paper is to be drawn ofl the roll. As the paper is drawn, it necessarily tends to depress the apron; gravity also tends to lower the apron; and as the guide swings on its axis the push rod moves until the apron forms an extension of the guide.

Although the paper drawn from the roll can be brought directly against the front edge 37 of the frame 4, I prefer to provide a bar 38 on the edge against which the paper is drawn and which facilitates the formation of a smooth curve in the paper about the knife, which aids the paper to support the knife before the paper is severed. The

edge 37 of thebar 38 forms a support for the paper toward which the paper guide 1s moved when the paper on the guide is pulled off the roll, the catch retaining the guide at the paper support. The knife is unable to operate the catch for the paper resting on the support prevents the knife from dropping until the paper is severed, when the weight of the knife operates the snap hook and allows the guide to return to its normal position.

We claim:
