Improvements in Rosin-boxes for Violinists' Use, also applicable for
other purposes.
"
I, LOUIS LÖWENTHAL of the Firm "The Lowendall Star Works
of 121,
Reichenbergerstrasse, Berlin, in the Kingdom of Prussia, Enpire of Germany,
Manufacturer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
My invention relates to an improved rosin-box, which I call "Lowendall's.
Rosina," destined to preserve the piece of rosin or colophony generally used for
violin-bows, and to move the said piece of rosin forward in such a manner that
the top projects from the box, while the body of the piece of rosin remains in
the box in a protected position. By gradually moving the piece of rosin forward,
only the top surface projecting from the box will be worn out, and the wear will
proceed down at a uniform rate, so that the rosin may be used up to the last
stump.
The said box may equally be used to preserve and move forward a piece of wax,
or hard pomatum, or any other matter of the kind.
In the accompanying drawings :-
Figure 1 is an outside view of the rosin-box:
Figure 2 is a central vertical section of the same: and
Figure 3 is a cross section drawn to line of Figure 2.
A, is a box or shell, preferably of sheet metal and open at both ends, the upper
end may be closed by a cap A¹, not shown in Figure 2, and the lower end is
provided with a similar bottom cap A", turning on the cylindrical surface of the
lower end of the shell A. In the central portion of the bottom cap A", a screw
spindle B is rigidly fixed, and on the said spindle is mounted a nut C, carrying a
plate or disc D, the rim of which may be slightly turned up, as shown; to form a
cup, or which may be flat, as desired. The said disc or plate D has in its
circumference a recess d, through which extends a spring E, secured inside the
shell A. By means of said spring E, engaging with the recess d of the plate D,
the said plate is prevented from turning when the bottom cap of the box A is
being turned. It will be easily understood, then, that, by turning the cap A" on
the shell A, the disc or plate D, on the nut C, will be moved along the screw
spindle B in either direction. The piece of rosin or other solid matter F, having
a central bore and being placed on the said spindle B with its lower surface resting
on the plate D, will be shifted forward to project from the top of the box A as the
bottom cap
A is being turned to the right, and it will be returned into the box as
the cap A is being turned to the left. The speed of motion in either direction
depends on the pitch of the screw.
The spring E, preventing the plate D from turning, may equally serve to lock
the bottom cap A against being drawn from the shell A, on which the said
cap A is loosely fitting. To obtain said locking, the lower end e of the spring E
may be hook-shaped to engage with a recess in the cap A", by which means the
cap is secured against falling or being drawn from the shell A. A pin el, secured
to the spring E and projecting through a hole in the shell A, serves to lift the
said spring E out of engagement with the cap A" when it is desired to remove the
said can A 11

page_text: 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. In a box destined to gradually move forward the piece of rosin or other
consistent matter preserved therein, the combination, with a shell or cylindrical
body, of a bottom cap arranged to turn on the lower end of said shell, a screw
spindle fixed to the bottom of said lower cap and projecting upward inside the box,
a nut fitted on said spindle, a disc or plate carried by said nut, and means for
preventing said dise or plate from turning along with the bottom cap, substantially
as and for the purpose set forth.
2. In a box destined to gradually move forward the piece of rosin or other
consistent matter preserved therein, the combination, with a shell A, of a bottom
cap A, arranged to turn on the lower end of said shell, a screw spindle B, carried
by said bottom cap, a nut C fitted on said screw spindle, a disc or plate D carried
by said nut, and a spring E, serving to prevent said disc or plate from turning and
also to lock the bottom cap to the shell, substantially as and for the purpose set
forth.
