ORCHESTRA 0R STREET DRUM
Sidney H. Newberl'y, Laurel Springs, N. J.
Application April 7, 1936,v Serial No. 73,104
5 Claims.
(Cl. 84-411) .
This invention relates to musical instruments
and more particularly percussion drums, in gen
eral banjos, ukuleles and mandolins, using
membrane heads and generally to a musical in
5 strument using a stretched membrane head, has
particularly to do with mechanism for tighten
ing the membrane and is an improvement upon
the prior Patent No. 1,901,765, granted March
14, 1933, for Drum head tightener.
An important object of the invention is the
10
elimination of the use of tension rods of the usual
type and more speci?cally the retainers employed
in my prior construction, so that the exterior of
the drum can be made smooth and the drum shell
15 will be left free for engraving or other adorn
ment without interference from such elements.
A further object of my invention is the pro
vision of means in a drum whereby the drum
may be readily converted from the orchestra type
to the street drum type.
A still further object of the invention is the
provision of means whereby a double adjust
ment of the drum head may be effected in ap
plication thereof, that is to say in applying the
25
drum head to one or the other of the types of
shells for which it is adapted, the head may be
given a differential adjustment independent of
the adjustment effected after the general plan of
my prior patent aforesaid.
A still further object of the invention is to pro
30
vide means whereby the snares may be instanta
neously released from the drimi, thereby permit
ting its immediate transformation from the or
dinary snare drum. to any other type of drum.
These
and other objects are attained by the con
35
struction set forth in the accompanying draw
ings wherein
Fig. 1 is a perspective View of a drum con
structed in accordance with my invention.
Fig. 2 is a vertical sectional view therethrough.
Fig. 3 is a perspective view of the head adjust
ing mechanism common to both the batter and
snare heads of the drum.
Fig. 4 is a sectional view through the lower
45 part of the drum illustrating the positioning of
the snare adjustments.
Fig. 5 is a perspective view of the drum shell
sections.
Fig. 6 is an enlarged perspective view of the
50 snare release, and
Figs. '7 and 8 are perspective views showing
the different types of drum obtainable with the
use of my construction by minor manipulation.
Referring now more particularly to the draw
55 ings the numeral I0 designates the drum shell
which at its upper and lower ends has portions
ll of reduced diameter connected to the main
body of the shell by substantially horizontally
extending shoulders I2. The extremities of the
reduced portions are flanged inwardly and to
ward the center of the drum as indicated at [3
so that these upper surfaces may provide a
smooth surface for the reception of the mem
brane or head 14. Engaged with the shell Ill and
more particularly the main body thereof through 10
bayonet slots l5 are head tighteners l6, each com
prising a cylindrical wall ll, the upper end of
which is reverted in spaced relation to the outer
wall as indicated at [8, thus providing a chan
nel l9. Within this channel I9 is arranged an
upper cam ring 20 having a series of ratchet
like teeth 2| adapted to coact with a similar
cam ring 22 which lies against the wall I‘! at
the inner surface thereof and is held in position
by means of a lug or lugs 23 (which are carried
by said tighteners) engaging in slots 24, which
parallel the edge surfaces of the teeth of the
lower cam ring.
The upper cam ring may be
adjusted with relation to» the lower cam ring
through a rotating member 25 mounted in the
opposed walls provided by reverting the upper
end of the head tightener wall and provided with
a small pinion 26 engaging with racks 21 formed
on the upper and lower cam rings 2|] and 22.
The lower cam ring abuts directly against the
head hoop 28 forcing it downwardly in the an
nular channel provided between the inset por
tion of the shell and the wall ll of the tightener.
An additional quick tightening means is readily
provided by forming the bayonet slot I5 in its
normally horizontal position with a slight in
cline as shown, and by forming in this incline
portion and. more particularly the upper surface
thereof, a plurality of coves 29 in which the stud
or pin 30 may be selectively engaged.
40
Obviously with a structure of this character
it is possible to immediately interchange the
tighteners and heads associated therewith in
different types of shells so that the drum may in
the course of a few moments be converted from
the ordinary orchestra drum to a street drum and
vice versa. To accomplish this it is merely nec
essary that the tighteners be bodily rotated to
disengage the bayonet slot connections between
the shell then in use and the tighteners and then 50
to reverse the operation and secure the tight
eners to the second shell. Thus the cost of a set
of drums may be materially reduced. The lower
tightener has its reverted- portion equipped with
mountings for the snare.
These mountings are 55

designated as a tightener 3| and a release 32.
The tightener 3| needs no speci?c description
comprising merely the usual snare cord attach
ment 33 and adjusting screw 34 therefor. The
snare release, however, comprises a novel con
struction illustrated more particularly in Fig. 6
of the drawings. It is composed of a toggle in
cluding ?xed and movable elements 35 and 36,
movement of the movable element being guided
10 through slots 31 included in the bracket 39, in
which the mechanism is mounted. A lever 39’ is
pivoted in this bracket as at 4!] and has one arm
thereof connected by a link 4| to a pivot 42 con
necting the links 43 of the toggle mechanism.
15 Suitable cords 44 are attached to the lower or
movable element 36, and are passed up and over
the stationary member 35, which is arranged
in close proximity to the snare head and may
be adjusted with relation thereto by reason of
20 the fact that the securing elements attaching
the bracket 39 are passed through slots 45. The
toggle mechanism. is so spaced from the inner
wall of the bracket that the tension of the cords
44 will in the tightened position of these cords,
25 which corresponds to the extended position of
the toggle, tend to force the connected end of the
links 43 toward and against the upper Wall of
the bracket. The second arm of the lever 39' is
bent outwardly so that it is readily accessible
30 beyond the side wall of the drum and it is ob
vious that a movement of this lever in one di
rection will break the toggle and release the
snare cords, while a movement thereof in the
opposite direction will set the toggle and tension
35 of the cords. This arrangement permits of an
instantaneous release or restoration of the snare
action and accordingly permits the drum to be
instantaneously converted from the share to any
type of drum.
Since the construction hereinbefore set forth is
cap-able of certain modi?cations without depart
ing from the spirit of my invention and since the
invention is equally applicable to all types of in
struments employing stretched membranes, I wish
45 it to be understood that I contemplate any
changes within the scope of the appended claims
and likewise understood that the term “drum”
employed in these claims is understood to compre
hend all structures employing drum head arrange
50 ments.
I claim:
