COMPLETE SPECIFICATION.
Improvement in Roll Paper Holders and Cutters.
1, FREDERICK WILLIAM, DROSTEN of the City of St. Louis, in the State of
Missouri, United States of America, Jeweller do hereby declare the nature of this
invention and in what manner the same is to be perforined, to be particularly
described and ascertained in and by the following statement :-
My invention relates to a device for holding and cutting wrapping paper, and the
like, and relates particularly to an improvement on the invention on which Letters
Patent of the United States was granted to me the 21st day of June 1887,
No. 365,334.
My present invention consists in features of novelty hereinafter fully described and
pointed out in the claims.
In order that my invention may be properly understood and readily carried into
effect, I have hereunto appended one explanatory sheet of drawings in the several
figures of which corresponding parts are marked with the same letters of reference.
Figure 1 is a front elevation of my improved machine;
Figure 2 is a side clevation; and
Figures 3, 4 and 5 are detail views, shewing modifications;
Figure 5 being section taken on line V, V, Figure 4.
Referring to the drawings, 1 represents a suitable base, to which are secured end-
pieces, or standards 2, having extensions or arms 2ª.
3 represents the roll of paper, having journals 4, by which it is supported in the
standards 2.
The extensions or arms have ways or slots 5.
6 represents the knife, having a cutting edge 7, and having projections 8 that fit in
the ways or slots 5.
The slots 5 may be vertical, as shown in Figure 2, or they may be inclined, as
shown in Figure 3. At one side of the slot or way of each extension or arm are teeth
or notches 9, and to them my invention relates. The function of these notches or
teeth is that of engaging the projections S of the knife to prevent the upward
movement of the knife in cutting the paper. Thus, in the operation of the machine,
the knife moves downward by gravity as the size of the roll decreases, thus always
bearing on the roll, and when an upward pressure is brought upon the knife in the
act of cutting the paper, the projections 8 of the knife engage the notches or teeth 9
of the ways, and all danger of the knife being raised or elevated by the pressure of the
paper is obviated.
As stated, the ways or slots 5 may be arranged vertically or on an incline. They
are shown on an incline in my Patent referred to, and as another obvious modification,
the extensions or arms 2ª may be made with parallel sides, as shown in Figures 4
and 5, and the knife may be formed with openings providing two lugs 8 on each end
which embrace the extensions or arts; one side or face of each extension or arm
being provided with the notches or teeth 9.
The notches 9 may be made in one only or in both of the extensions or arms 2ª.
The notches are particularly adapted for use in a machine for cutting heavy wrapping
paper.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination with suitable standards for holding the roll of paper, of a
gravitating knife adapted to rest upon the roll of paper, and guided in its downward
movement by toothed or notched extensions or arms with which the knife engages

page_text: and is prevented from moving upward while severing the paper from the roll ;
substantially as described.
2. The combination of the standards, a knife guided and held by the standards, and
teeth or notches on one or both of the standards with which the knife engages,
substantially as and for the purpose set forth.
3. The combination of the standards having slots or ways, and teeth or notches, and
the knife having projections fitting in the slots or ways and engaging the teeth or
notches, substantially as and for the purpose set forth.
4. The combination of the standards 2 having notches or teeth 9, and the knife 6
having cutting edge 7 and projections 8, substantially as and for the purpose set
forth.
5. The combination of the slotted standards, a knife fitting and working in the slots
of the standards, and means preventing the back movement of the knife.
Dated this 11th day of August 1890.
