ROLL-PAPER HOLDER ND CUTTER.

SPECIFICATION vfornuing part of Letters Patent No. 423,798, dated March 18, 1890.

Application iled January 17, 1889. Serial No. 296,604. (Model.)

To all whom it 11a/ay concern:

Be it known that I, JOHN H. NENTRUP, a citizen'of the United States, and a resident of Covington, in the oountyof Kenton and State of Kentucky, have invented certain new and useful Improvements in Roll-Paper Holders and Cutters, of which the following is a speciiication.

My invention relates to that class of devices employed for holding rolls of Wrapping-paper and severing sheets of any desired size from the roll.

Its object is acheap compact device having no parts to weaken or get out of order, and in which the edge of the cuttingknife automatically adjusts itself to bear with sufficient pressure upon the roll from the time it is put into the frame until it is all used.

The invention Will be first fully described in connection with the accompanying drawings, and will then be particularly referred to .and pointed out in the claims.

In the drawings, in which like parts are indicated by similar reference-letters wherever they occur throughout the various views, Figure l is an end elevation of my device with a roll of paper mounted for use. Fig. 2 is a plan view of the same. Fig. 3 is an inside elevation of one of the knife-carriers. Fig. i is a perspective view of a modified form of the knife-carrier.

The roll-holder is composed of the base A, the two standards B B, and the Aupper crossbrace CAv The base A and brace C are preferably made of hard wood and the standards B of cast metal. The standards have upon the outside a longitudinal web or rib b for strength, and also to serve as a guide for the knife-carriers. The standards are notched upon one side to furnish bearings for the rolljournal. The Webs or ribs curve around at b to furnish wider bearings for the roll-journals. The upper part of the standard above the journal-bearings is inclined in the direction of the knife, in order that the cuttingedge may, as the roll diminishes, be carried in the direction of the axis. The knife D is mounted in carriers E, the ends of the knife being preferably dovetailed into the lower edges of the carriers, as seen in Figs. l and 3.

The preferred form of knife-carriers (shown in Figs l to 3, inclusive) are cast-metal anglepieces, each having the rounded corners c and ear e', from which ear projects a projection, such as a stud, pin, trunnion, or lug e2. y One of these angle-pieces E is secured upon each end of the knife, and the frame thus formed is dropped down over the standards B, the pin or lug c2 passing back of the ribs b and the rounded parts e passing in front. It will be seen that the weight of the knife tends to bring its cutting-edge down upon the roll F, and the relative position of the pin or lug e2 androunded corner of the an gle-piece E, bear ing upon opposite sides of the web b, as seen in Fig l, prevents the knife-edge from being thrown up by the act of tearing the paper, While permitting the edge to swing in the direction of the axis of the roll as the roll becomes smaller. The pressure of the knife is therefore the same Whether the roll be full or nearly empty, and a smooth even cut is insured at all times whether the paper be light or heavy.

In the modification shown in Fig. the carriers E are formed up from sheet-steel and are riveted to the ends of the knife, and it is evident that they may also be formed out of the same piece of metal as the knife-blade. In either case the parts or lugs e3 are to slide back of the ribs o and the parts or rounded corners c'l to slide in front. It is also evident that the base A may be dispensed with and the feet of the standards B secured directly ou the counter when the device is to remain permanently in one place. The top brace C is only for strength, and may be omitted if the standards are made sufficiently heavy.

\Vhat I claim ism l'. The combination, with standards having longitudinal ribs, of a weighted gravitating knife resting on the roll and provided at its ends With rearwardly-extending ears having projections which. engage With said ribs and are constructed to prevent the knife edge from being thrown up by the act of severing the paper, while permitting the downward tilt-V ing of the knife-edge as the roll diminishes in size, substantially as described.

2. The combination of the standards B, havree ing ribs l), and the knife having carriers E, secured upon each end, the said carriers having ears c', and lugs projecting from said ears to pass back of the ribs upon the stand- 5 ards, substantially as shown and described.

3. The combination, substantially as specified, of the standards B, connected together,

l n I as shown, and liavlng ribs b, and the knifefralne arranged to slide in front of said stand- Io ards and having lugs to pass back of the ribs h, whereby the knife is vertically guided and retained in position, for the purpose set forth.

L The combination, substantially as specified, of the base A, the standardsB b, notched to receive the journals of the roll andhaving,r 15 the upper ends above the journals inclined, as shown, the knife-carriers adapted to slide on said standards, each carrier being formed with a rounded corner, a rearwardly-projecting ear, and a lug on the ear, and the knife zo D, secured to the forward and lower ends of said carriers, for the purpose set forth.
