"MR. COLLARD'S PATENT. - A Patent (for the United Kingdom) for
Improvements on Piano Fortes has been recently obtained by Mr. W. F.
Collaro, of the House of Clementi, Collaro, and Co. London.
The object of Ma. Collard's invention is however general, and it imparts
not only a new and richer degree of tone, but it submits a choice of
fresh varieties and degrees to the player, which can hardly fail to call
forth novel and beautiful effects in performance.
The mechanism used having been already brought to a very high degree of
excellence, it seemed manifest that if the qualities sought after could
at all be produced to the extent desired, they must either result from a
new construction of the soundboard, or from the mode of applying the
strings, or from both means combined.
The improvement that is the basis on which the other is founded, is an additional bridge on the sound-board, not for the purpose of regulating musical intervals, but of augmenting the duration of the vibration, and consequently increasing and beautifying the tone. This bridge, which he calls "the bridge of reverberation," is placed at a regulated distance on the sound-board; and the important advantage resulting from it is, that the motion given to the principal part of the string by the impulse of the hammer is kept up by the bridge of reverberation, instead of being suddenly checked by an attachment to an unyielding substance.
The prolonged vibration produces an extraordinary purity, power, and
continuity of sound somewhat resembling the richness of an octave below.
The performer, by lifting a valve, is enabled to elicit those harmonious sounds through a well-known sympathetic relation between accordant strings, without touching those portions of the strings which produce them.
The augmentation of sound caused by this means resembles in some measure the effect of lifting the dampers, but without producing the same confusion, since every note on the body of the instrument is regularly damped as the performer lifts his finger.
By this apparatus a threefold power of augmenting the sound is acquired;
whereas instruments of the common construction have but the one caused
by lifting the dampers.
That which we heard appeared to us to produce the kind of prolonged tone which arises in a room of fine resonance, and the power was certainly vastly augmented. Upon the whole, the inventor seems to have accomplished far more than could have been expected after the very high state of improvement the piano forte had already attained."

Self-Acting Pianoforte :
Penny Magazine of the Society for the Diffusion of Useful Knowledge, 16/02/1839 p. 64
"SELF-ACTING PIANO-FORTE. - When the self-acting organs were invented, the musical public gave great credit to the contrivance, and afterwards took honorable notice of the improvements devised by the ingenious and persevering firm of Clementi, Collard, and Company.
But the attention which their creative labours, as displayed in various instrumental constructions, drew to their manufactory, has been greatly increased by their very novel invention of a self-acting piano-forte.
This curious instrument, furnished with a horizontal cylinder, similar to that of a barrel-organ, and put into motion by a steel-spring, performs without external force or manual operation, the most intricate and difiicult compositions; and, by comprising in its mechanism two complete instruments, each independent of the other, it admits, while the operation of the self-actuated intrument is proceeding within, of a distinct accompaniment on the keys without, which occupy the usual place in front, and may be played on at pleasure, with or without the self-acting part of the machine.
This first instrument of its kind, when the spring is fully wound up, will act for more than half an hour, and may he again prepared for performance in half a minute; and, if required, stopped in an instant, while in full action.
The time in which it
executes any movement, may be accelerated or retarded, at pleasure: and
while, by the delicacy and perfection of the mechanism, the piano and
the forte passages are given with correctness and effect, the fortzandi
and diminuandi are produced, by the slightest motion of the hand applied
to a sliding ball at the side of the instrument. When we consider the
state of the piano-forte as originally constructed, — its thin, wiry,
jangling tone, inaffective weakness, and other numerous imperfections,
and witness the complicated beauties and powers of this self-acting
instrument, we must be both delighted and surprised, — and almost be
persuaded, that to ingenuity, science, and industry, no excellence in
musical mechanism is unattainable."

ON A NEW CONSTRUCTION OF PIANO-FORTES.
Patent of 1828 ? : "The Parisians have laid claim to great improvements in piano-fortes by the application of iron in the structure of the case ; but that improvement, as far as its utility goes, has long been in use in England.
The plan of employing one large string to each note of the piano-forte, upon which the Parisians also dilate largely, is another invention, if it may be so called, likewise derived from this country.
Lord Stanhope was amongst the first who made this attempt, but the false and crazy tone rendered by the treble strings, particularly when so enlarged as to produce the quantity of tone required, was an insurmountable obstacle to its success.
This is precisely the case with respect to the French instruments; and those made in this country with strings of less diameter, although not so loud, are of very superior purity.
In the French square
piano, in order to apply the mechanism used in grand pianos, the
manufacturers are obliged to place the hammers diagonally to the
direction of the key, and this sidelong motion is a great defect.
The case of the square piano-forte is somewhat larger than those usually made, and varied from their usual form, not from necessity, but to improve the elegance of its appearance.
The sound-board is prolonged over the whole internal surface of the instrument, in order to increase and enrich the tone.
One important improvement is effected in the mode of applying the damper, the wire of which does not pass down immediately next the strings it is intended to damp, but is placed beyond the two succeeding semitones higher up the instrument, and the damper head is made longer, so as to reach over to the note to which it | is applied.
By this important
change, sufficient space is 32 left between the hammer head and the
damper wire to introduce the grand piano-forte check, to arrest the
hammer in its descent, and prevent its reverberation against the
The object of this is to prevent the distortion of the fibres of the wire by twisting, which often makes them false, to obviate the giving of the wire at the noose, and to avoid the frequent snapping of the string at the twist.
Not with standing that both unisons are made by one continuous wire, yet such is the tenacity caused by the friction on the single hitch pin, that one of the unisons may be lowered several semitones without in the least affecting the pitch of the other.
So great is the
advantage gained by this mode of applying the strings, that a string is
seldom or never known to break; it is brought up to its pitch almost
instantaneously, and a person who has never before put a string on a
piano-forte may do it without the smallest difficulty.
The tone is rich, and of a volume approximating to that of a grand piano-forte. The vibration is prolonged and pure, and highly calculated for expressive as well as brilliant playing.
The touch is in every respect equal to that of a grand piano-forte, and it is from these two qualities of tone and touch, that, we apprehend, the proprietor of this invention has styled the instrument "grand square piano-forte."
It is an instrument well calculated to attract the attention of those who are unwilling to be at the expense of a grand piano-forte, or whose rooms would be too much incumbered by its size, for no professor would hesitate to perforin a composition requiring great power of instrument on such a one as we have described, the tone and touch of which cannot fail to satisfy any performer.
The same makers have
manufactured a few of these instruments of larger dimensions, by which a
greatly increased volume of tone has been obtained; and having also
applied metal centres to the hammers, they still more approach the
perfection of the grand pianoforte."
