Improvements in Musical Drums.
I, BENJAMIN JOSEPH BARNARD MILLS, of 23, Southampton Buildings, in the
County of London, Patent Agent, do hereby declare the nature of this invention
(a communication to me from the Firm of A. Osmanek, of Schönbach, Bohemia,
in the Empire of Austria) to be as follows; -
The present invention relates to improvements in the arrangement of the snares
in drums as well as to a new tension-device for. the said snares.
According to this invention the snares are arranged in the interior of the drum
along the two drum heads and are provided with a tension device which can be
actuated from the outside of the drum. A spring equalizing the tension is
arranged between the two sections of the drum snares which are stretched along
the upper and the lower drum heads.
The accompanying drawing shows in vertical section a drum provided with
the improvements above mentioned.
a is the upper head at the lower head of the drum. Both drum heads can be
stretched in the well known manner by means of the tension hoops 6 b' and the
screw bolts 6º.
The drum snares c are arranged in the interior of the drum and are stretched
diametrically in proximity to the drum heads over guide-staples c¹ fixed to the
drum cylinder d.
Between the upper and the lower drum snares c, a spiral spring is arranged
on one side and a tension or stretching device on the opposite side. The latter
consists of a flat rod f with screw threads on its two opposite edges, the rod being
guided in a socket f¹ in such a manner that it can move in a longitudinal direction
but is prevented from turning around its axis. This rod has on one of its ends
a hook to which the upper drum snares are affixed and passes through a screw
nut f3 arranged between the arms of a strap f* fixed to the drum casing d, whereby
all motion of the nut 3, except that of rotation is obviated. The milled edge of
the screw-nut 3 passes through a slot of the drum casing d to the outside and can
thus be easily rotated.
The lower drum snares are connected at one end with the spiral spring d'
which equalizes the tension and at their other end with a fixed eye f.
If the screw nut f³ is rotated from the outside the rod f is moved lengthwise
in the socket f1, the drum snares being thus loosened or strained.

I, BENJAMIN JOSEPH BARNARD MILLS, of 23, Southampton Buildings, in the
County of London, l'atent Agent, do hereby declare the nature of this invention
(a communication to me from the Firm of A. Osmanek, of Schönbach, Bohemia,
in the Empire of Austria) and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:-
The present invention relates to improvements in the arrangement of the snares
in drums as well as to a new tension-device for the said snares.
According to this invention the snares are arranged in the interior of the drum
along the two drum heads and are provided with a tension device which can be
actuated from the outside of the drum. A spring equalizing the tension is
arranged between the two sections of the drum snares which are stretched along
the upper and the lower drum heads.
The drawing accompanying my Provisional Specification shows in vertical
section a drum provided with the improvements above mentioned.
a is the upper head a¹ the lower head of the drum. Both drum heads can be
stretched in the well known manner by means of the tension hoops 6 6' and the
screw bolts 62.
The drum shares are arranged in the interior of the drum and are stretched
diametrically in proximity to the drum heads over guide staples c¹. fixed to the
drum cylinder d.
Between the upper and the lower drum snares c, a spiral spring d¹ is arranged
on one side and a tension or stretching device on the opposite side. The latter
consists of a flat rod with screw threads on its two opposite edges, the rod being
guided in a socket f¹ in such a manner that it can move in a longitudinal direction
but is prevented from turning around its axis. This rod has on one of its ends
a hook f to which the upper drum snares are affixed and passes through a screw
nut 3 arranged between the arms of a strap f* fixed to the drum casing d, whereby
all motion of the nut f³ except that of rotation is obviated. The milled edge of
the screw nut f³ passes through a slot of the drum casing d to the outside and can
thus be easily rotated.
The lower drum snares c are connected at one end with the spiral spring d¹
which equalizes the tension and at their other end with a fixed eye. f.
If the screw nut f3 is rotated from the outside the rod f is moved lengthwise
in the socket f', the drum snares being thus loosened or strained.
Having thus 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 drums the arrangement of the snares in the interior of the drum in such
a manner that these snares c are stretched over guide-staples c¹ and are connected
with a spring d for the compensation of the tension and with a stretching device,
substantially as described and shown.
2. In drums of the kind referred to in Claim 1, the arrangement of a stretching
device for the snares actuated from the outside, said stretching device consisting
of a screw threaded rod f connected with the drum snares and prevented from any
rotatory motion, and of a nut f³ accessible from the outside which, when rotated,

page_text: produces a vertical displacement of the rod f and thereby the stretching or the
loosening of the drum snares, substantially as described and shown.
