1 WITNESSES: INVENTOR: 6% 8 i 77M l BY i /fl AJ UNITED STATES PATENT OFFICEO JOHN A. CARTER, OF ROSE BUD, ILLINOIS.
MECHANICAL MUSICAL INSTRUMENT.
SPECIFICATION forming part of Letters Patent No. 226,714, dated April 20, 1880.
Application filed December 10, 1879.
To all whom it may concern:
Be it known that 1, JOHN A. CARTER, of Rose End, in the county of Pope and State of Illinois, have invented a new and useful Improvement in Mechanical Musical Instruments, of which the following is a specification.
My improvements relate to the class of musical instruments wherein hammers are employed to strike upon wires or other resonant material arranged in any usual manner and the movement of the hammers obtained by a perforated music-sheet that is fed by a crank, such as shown in the Letters Patent granted to O. H. Arno, January 1, 1878.
The object of my invention is to improve the tone of the instrument and feed the musicsheets with case and regularity, and avoid jumps and stops in the movement; and the invention consists in the use of a sounding-box and in a counter-pressure roller and ratchetwheels and pawls, which are combined with the crank and sheet-guides in a manner to attain the objects named.
The construction and operation will be more particularly described with reference to the accompanying drawings, wherein- Figure 1 is a plan view of the instrument. Fig. 2 is a vertical transverse section on line 00 0c of Fig. 1.
Similar letters of reference indicate corresponding parts.
A is the sounding-box, which is to contain the resonant wires or strips, and will be fitted with the hammers, that operate in the usual manner. They being well known are not shown and do not need description. ais the passage for the music-sheet, formed in the box A, the sheet entering at the top beneath guides b and coming out at the bottom. 0 is the lower roller, and d the upper roller, between which the sheet enters. The roller 0 is on a shaft fitted with a crank, c, by which the sheet is fed forward.
f is the counter press-roller, fitted on a shaft above roller d, which shaft is sustained in suitable bearings and carries ratchet-wheels g g at opposite ends of roller 1'. h is a rock-shaft,
fitted in bearings at the rear of roller f, and provided with a crank that is connected by a rod or pitman, i, with the crank c. The shaft h is also formed with cranks 7c is at its opposite sides, to which crank the pawls l l are connected and extend to the ratchet-wheels g g, upon which the pawls rest.
The pressnre-rollerf is, by preference made in the rounded form shown, and bears upon the upper roller, d, so as to give rotation to d and cause the same to bear on the music-sheet with more or less pressure. This pressure may be regulated by any suitable devices, as a screw and nut.
In operation the music-sheet will be entered between the rolls 0 d and fed forward by turning the crank c. The motion given to the rock-shaft h by its connection to crank 0 will cause a back and forward movement of the pawls I, and the pawls, by engagement with the ratchet-wheels g, will rotate the rollers f and d. The pawls l being at opposite sides of the rock-shaft, one moves forward while the other moves back, so that a continuous motion is given to the roller f. By these means the music-sheet will be carried forward at a uniform speed without stops or jerks.
The entrance and exit of the passage a may be fitted with friction-rollers for the sheet to pass over, so as to facilitate its movement.
The sound-box A may be made of any desired form or size and mounted on legs to give the instrument the appearance of a piano. The volume and sweetness of tone are greatly increased by the use of the sound-box and there is room for the addition of coiled springs for a sub-bass.
In Fi 3 is shown a modification of the pawl, whereby I obtain a noiseless movement. g is the ratchet. on is a rocking fulcrum having its bearings on the shaft of counterpress rollerf. n is a fly-hook, hung at its upper end by a bolt to the rocking piece m, and its lower end engaging the ratchet g. The arm 1 is connected with hook it by a bolt enterin g a slot in piece 112. As arm Zmoves backward it lifts hook it and moves m. On the re turn the arm Z draws hook it, which engages ratchet g, turns roller f, and returns piece m. This movement is noiseless.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a mechanical musical instrument, the
sounding-box A, for containing the action, 3. Infeed mechanismfor mechanical musical formed with the passage a, for the music-shect, instruments the pressure-roller f, ratchets g, and provided With feeding mechanism, all rock-shaft h, pawls Z, and pitman 2', combined combined and arranged to operate substanwith the crank e and rollers a d, substantially I5 5 tially as described and shown. as and for the purposes specified.
