BACKGROUND OF THE INVENTION
This invention relates generally to control of striking of percussion instruments, and more particularly to an improved beater construction facilitating enhanced control of striking of drums and drum heads.
During beating of a drum, a drummer may seek to control the movement of a beater or mallet to vary its impact with a drum head, for example to produce a softer or louder sound, or otherwise variable sound. This control is made more difficult by the construction of beaters that present a uniform beating surface to the drum.
There is need to overcome this difficulty or problem, and in such a way as to enhance controllability as well as to increase the range of tones producible by drumming.
SUMMARY OF THE INVENTION
It is a major object of the invention to provide a solution to the above described problems and difficulties, as well as to provide an improved beater construction. The improved beater of the invention comprises,
- a) an elongated stem, and
- b) a beater head carried by the stem, and having:
- i) a relatively hard drum striker
- ii) a relatively soft drum striker,
- c) both of said strikers facing in the same direction, to strike a drum head.
As will be seen, the relatively soft striker may consist of resiliently compressible material; and the relatively hard striker may be metallic, or of other hard material. Further, the relatively soft striker may consist of cushioning material formed as a block or blocks, and may extend at opposite sides of the metallic striker to yieldably engage a drum head to substantially equal extents at opposite sides of the hard striker.
Another object is to provide a relatively hard striker forming a drum striking surface having first and second portions facing forwardly, said first portion protruding forwardly relative to said second portion. Such first and second portions may define a dome that is forwardly facing and may be forwardly convex. In this regard, the relatively soft striker may extend at opposite sides of the relatively hard striker to face sidewardly and openly toward angled extents of the hard dome.
Apparatus to swing the hard and soft striker forwardly may include a pivoted foot plate, an axle supporting the stem, and structure operatively connecting the foot plate and axle to rotate the axle in response to displacement of the foot plate.
Yet another object is to provide an adjuster operable to adjust the relative positions of the strikers. As will be seen, a base may be provided, and to which the relatively soft striker is connected, the adjuster being rotatable relative to the base to advance or retract the relatively hard striker relative to the relatively soft striker.
These and other objects and advantages of the invention, as well as the details of an illustrative embodiment, will be more fully understood from the following specification and drawings, in which:

DETAILED DESCRIPTION
FIGS. 1 and 2 show a drum beater or mallet 10 having an elongated stem 11 and a beater head 12 carried by the stem. The head 12 includes a relatively hard, as for example metallic drum striker 13, and a relatively soft drum striker 14. Both face in the same direction indicated by arrow 15 to strike a drum head, as the stem 11 moves in that direction. Striker 13 has a hard surface 13a facing in direction 15, and striker 14 has a soft surface or surfaces 14a facing in direction 15. The striker 14 and surface 14a may consist of resiliently compressible foam rubber, or other elastomeric material, or felt, and surface or surfaces 14a extend or extends at opposite sides (for example above and below) striker surface 13a. Note upper surface extent 14a′, and lower surface extent 14a″, which are generally alike, whereby induced deflection of a drum head by simultaneous impact of surfaces 13a, 14a′ and 14a″ may be substantially balanced. Striker 14 may comprise a block of compressible material forming an opening or bore 16 in which metallic striker 13 projects forwardly, from a base 17, to which striker 14 may be attached at 17′. Surface 13a may comprise metal, plastic, wood, or other material significantly harder than foam rubber.
Referring now to FIGS. 4 and 5, the hard surface 13a has first and second portions facing forwardly, the first such portion protruding forwardly relative to the second portion. One way this is effected is by shaping such first and second portions in the form of a dome facing forwardly. See for example dome first portion 18 defining a crest, and dome second portions 19 and 20 at opposite sides of 18, and angled or sloping rearwardly, whereby 18 protrudes forwardly relative to 19 and 20. The dome preferably may form a curved surface, shown. Surfaces 19 and 20 may be alike in extent, curvature and angularity.
FIG. 4 shows the condition where the drum head 21 is impacted with lesser force F1, by the beater head. The compressible striker is resiliently compressed by amount or amounts t1 both above and below the crest 18 of the metallic striker, and only that crest portion of lateral dimension S1 crosswise of the striker engages the drum head, to produce a relatively soft sound.
FIG. 5 shows the condition where the drum head 21 is impacted with greater force F2 (F2 exceeds F1), by the beater head. The compressible striker is resiliently compressed by amount or amounts t2 (where t2 exceeds t1), both above and below the crest 18 of striker 13. Not only crest 18, but also portions 19a and 20a of 19 and 20 engage the drum head, to produce a relatively louder sound. The dome surface extent of wider dimension S2 now impacts the drum head. In this regard, the compressibility of striker 14, at surfaces 14a, controls the extent to which the convex surface of the dome of 13 impacts the drum head.
FIG. 3 schematically shows one form of apparatus 30 applicable to swing the beater head and stem in a forward direction toward a drum, as the drummer's foot depresses a pivoted foot plate 31, with controllable force, i.e. to produce selected forces F1 and F2 described above. Other controllable forces are of course usable.
Apparatus 30 also includes an axle 33 supporting the stem 11, as well as structure 34 (such as a belt or chain) connecting the forward portion of the plate 31 to a hub or sprocket 35 on axle 33, as is known.
FIG. 1
a shows a capability for adjustment of the position of striker 13 relative to striker 14, in the forward direction. An adjuster 70 is rotatable to advance or retract 13 relative to 14. Adjuster may have threaded engagement to base 17, so that it moves axially, with the striker 13, as it is rotated. Coupling of the striker to the adjuster is indicated at 73. Striker 14 is attached to the base at 74.
In the modification of FIG. 6, a beater head 80 is carried by stem 11. Head 80 includes upper and lower plates 81 and 82. Plate 81 defines a relatively hard striker or drum striking surface 81a; and lower plate 82 carries a relatively soft, compressible striker, or drum striking surface 82a. A slot 83 is formed in plate 81, and a threaded fastener stem 84 projects downwardly through the slot into threaded bore 84a in plate 82. When head 85 of the fastener is rotated in one direction, plate 82 is loosened and can be shifted endwise in direction 86 or direction 87, to adjustably position surface 82a relative to surface 81a. When head 85 is rotated in the opposite direction, the plates are clamped together at interface 88. If surface 82a projects forwardly of surface 81a, the drum head is first struck by 82a and then by hard surface 81a. The extent to which compressible surface 82a project forwardly of 81a determine the impact of the drum head by 82a and 81a, and therefore the resultant sound.
FIG. 7 shows a reverse construction. Lower plate 91 now defines the relatively hard striker, or drum striking surface 91a; and upper plate 92 carries a relatively soft compressible striker, or drum striking surface 92a. Slot 93 is formed in plate 92, and threaded fastener stem 94 projects downwardly through the slot into threaded bore 94a in plate 91. Plate 91 can be adjustably shifted when the fastener head 95 is loosened, and fixedly positioned when the head is tightened. The extent to which compressible surface 92a projects forwardly of hard surface 91a determines the the impact of surfaces 91a and 92a against the drum head, and the resulting sound.
