DESCRIPTION OF THE PREFERRED EMBODIMENT The numeral 10 refers generally to a conventional piano having a keyboard 12. The numeral 14 refers to the bass keys on the keyboard which are pivotally mounted on the pivot 16. Each of the keys 14 are operatively connected to its respective piano string in conventional fashion so that depression of the key will cause the strings to be sounded.
The numeral 18 refers to a foot pedal assembly comprising thirteen foot pedals 20 which are pivotally mounted as will be explained in more detail hereinafter. Inasmuch as each of the foot pedals are substantially identical, only one pedal 20 will be described in detail. As seen in FIG. 4, a collar.22 is secured topedal 20 by welding or the like. Pin 24 extends through ears 26 and 28 and the collar 22 to provide the pivotal connection between the pedal 20 and the support 30 to which the ears 26 and 28 are welded. The upper end of the pedal 20 is provided with a horizontally disposed portion 32 which normally engages the horizontal portion 34 of the support 30.
Nut 36 is welded to pedal 20 as seen in FIG. 4 and has a bolt member 38 threadably extending therethrough. Return spring 40 is mounted on the innerend of the bolt 38 and engages the support member 30 as seen in FIG. 4 to maintain the pedal 20 in the position of FIG. 4. The bolt member 38 may be adjustably threadably moved with respect to the nut 36 to provide an adjustment forv the amount of depression of the pedal. It can be seen that the inner end of the bolt 38 will engage the support member 30 and any threadable adjustment of the bolt member 38 with respect to the nut 36 will change the amount of depression permitted to the pedal 20.
Nut 42 is welded to the upper surface of horizontal portion 32 of pedal 20 and has a bolt 44 threadably received therein. A lock nut 46 is threadably mounted on the bolt 44 to securely lock the bolt 44 in the nut 42 and to permit adjustment therebetween. An adjustment nut 48 is also threadably mounted on the bolt'44 as seen in FIg. 4. Bolt 44 is provided with an opening 50 formed therein which is adapted to receive rod 52 therein. Collar 54 embraces bolt 44 between the nut 48 and the opening 50 so that upward threadable movemerit of the nut 48 will urge the collar 54 into engagement with the rod 52 to prevent movement of rod 52 in the opening 50. It can also be seen that the collar 54 and nut 48 permit the rod 52 to be adjustably positioned in the opening 50 as desired. 1
Rod 52 is provided with an eye portion 56 on its inner end adapted to receive the lower end of rod 58 which is provided with external threads at the lower end thereof. A pair of adjustment nuts 60 and 62 are threadably mounted on the rod 58 as seen in FIG. 4 to securely fasten a rod 58 to the rod 52 and to permit the vertical adjustment of rod 58 with respectto eye portion 56. The numerals 64 and 66 refer to felt washers positioned between the nuts 60 and 62 and the eye portion 56 respectively.
' tively and extend through suitable openings 80 formed in the member 82 positioned beneath the keys. Opening 80 is provided with an enlarged portion 84 at its upper end which receives an O-ring 86. Each of the push rods extend through the O-ring 86 and has a felt disc 90 secured to its upper end which is adapted to engage the underside of the key. If desired, the disc 90 can be secured to the underside of the key. A felt washer 92 embraces the upper end of the push rod beneath the upper end portion as seen in FIG. 3. The push rods 76 and 78 are spaced apart so as to engage the bass keys which are positioned an octave apart.
Nut 94 is secured to the forward side of horizontally disposed portion 70 and threadably receives the upper end of the rod 58 as illustrated in FIG. 3. Lock nut 96 is also threadably mounted on the upper end of the rod 58 to prevent rotation of the rod 58 with respect to the nut 94 and to permit the length adjustment of the rod 58 with respect to the nut 94. As previously stated, each of the spanner elements 68 are substantially identical. The only difference in the various spanner elements is in the vertical height of the push rods 76 and 78 as depicted in FIG. 5. The difference in the vertical height of the push rods and the offset of the push rods with respect to the horizontally disposed portion 70 together with the offset of the nut 94 with respect to the horizontally disposed portion 70 permits the spanner elements to be positioned beneath the keys so that all of the push rods are disposed in the same vertical plane. The relationship just described also permits all of the rods 58 to be positioned in the same vertical plane. FIG. illustrates the fact that the push rods of the respective-spanner elements 68 engage the bass keys of the piano an octave apart. The push rod 78 on the left hand spanner element 70 and the push rod 76 on the right hand spanner element 68 engage the same bass key which is referred to generally by the reference numeral 98. The fact thattwo push rods engage the same key requires one of the push rods to be slightly bent to permit their positioning. 1
The apparatus of this'invention permits a person who is familiar with an organ but unfamiliar with a piano to readily adapt to the piano'since the foot pedals may be individually depressed to actuate the bass keys of the piano. The bass keys will be actuated an octave apart. The fact that all of the push rods of the spanner elements are in the same vertical plane and the fact that all of the rods 58 are in the same plane results in the keys being able to be actuated with an equal amount of push pressure. In other words, it does not require different push pressure to actuate the different bass keys.
ratus'of this invention also permits the piano to be played to achieve different rhythms, for example shuffle, rumba, cha-cha, waltz, four/four-two beat, four beat bass, four beat bass with double lead, etc.
Thus, it can be seen that a novel foot operated piano playing device has been disclosed which permits the bass keys of the piano to be actuated so as to sound the piano strings an octave apart upon depression of an individual foot pedal. It can therefore be seen that the invention accomplishes at least all of its stated objectives.
