DESCRIPTION OF THE DRAWINGS.
Fig. 1 shews an upright pianoforte action with one part of my invention applied
thereto.
In this arrangement, a is the sticker of ordinary construction lifted by key b.
c is ordinary hammer, having however a forked prolongation cl, which embraces the
adjustable pin a', which is threaded and, the thread of which engages a threaded
hole pierced diagonally through the sticker . a² is a button on the end of the
pin a and this button sets off, as the pin a¹ is adjusted, against the incline d¹ formed
on, or applied, to the hammer rail d, thus combining the parts so as to afford
adjustability of "set off" and lateral guidance of the sticker relatively to the
hammer. is a balance head of metal, to engage the front face of the check 9,
thus securing a cheap and simple "check."
Fig. 2 shews the tail of the butt c, formed as a central pin a³, and forming a
guide for the forked part a* projecting from and forming part of the sticker a.
a' is a
Fig. 3 shews a modification of Fig. 1, adapted to a sticker a having a solid
"check" and engaging a notch in the hammer butt c. In this arrangement the
spring e for returning the hammer c is applied on the butt flinge d² to press against
the butt c instead of being applied on the sticker a, to draw the butt c.
spring applied in front of the sticker a, connected to a loop as, which passes through
a slot a in the sticker a, to, and so as to be fastened to, the hammer rail & thereby
drawing the sticker to its work.
Fig. 4 shews a modification of Fig. 1, in which instead of the lateral guidance to
the sticker a being obtained by the pin passing through the hammer tail fork c',
the pin a' here receives guidance from a separate fork hinged at f¹ in the slot
of the butt flinge d².
Fig. 5 is another modification, in which lateral guidance of the sticker is attained
by forking the upper end of the check y and causing the balance head shank e² to
travel therein. is the shank head, which is covered on its lower inner side to
check against the covered front surface of check head, and this is combined with an
adjustable "set off," attained by the attachment, or formation, of the incline a' on
the sticker, which sets off against the button on the end of the adjustable screw
pin screwed through the flinge d².
In the modification, Fig. 6, the incline a' is formed movable on the sticker a, by

page_text: hinging it thereto by its arm a³ at aº, so as give greater lift to the damper head h,
from the stringi (see Fig. 1) by the increased motion imparted to the damper
wire j, and the shank ³ carries a forked head e* which embraces an adjustable
wire a screwed into the sticker. a and carrying the button a", which adjustably
checks the head c³, and thereby the hammer.
In the modification, Fig. 7, the lateral guidance of the sticker, relatively to the
hammer, is attained by the forked tail of the hammer e embracing a hinged'
incline piece e, pendent therefrom, but controlled by the tension loop, or spring c³,
attached to the fork c', drawing the incline c constantly rearward, whilst the
curved pin c, fixed in the piece c', travels in the slot a¹², formed in the sticker a,
affording support thereto. a is an adjustable stop for the incline c¹ to set off
against.
In the modification, Fig. 8, the lateral guidance, or support, of the sticker is
attained by the pin c', adjustably fixed in the tail c¹ travelling in the slot a¹ in the
sticker a, whilst the adjustment of "set off" is attained by regulation of the screw
pin a, applied in the sticker head, and adjustment of checking by the screw pin c³,
carried in the head. The hammer tail has hinged to it the arm k¹, carrying
the damper head k, and by screwing the pin c so as to cause it to more or less
protrude through the tail c¹ rearward, the damper arm will be caused to damp the
wire, with greater, or less, promptness.
Fig. 8 shews a modification of Figs. 7 and 8, the arrangement therein shewn
embodying portions of cach. The hammer rail d, supports by the flinged, the
hammer butt c, from which is carried the check head c³; prolonged from the butt c,
is the tail c', which carries the arm k', and damper k; to the butt c are also
attached the flinges (1) (one on each side of the butt) carrying the hinged incline
piece e, carrying the guide pin c, which passes through and guides the sticker a.
The button a sets off against the incline c
Fig. 9 shews another modification in which some parts of the previous action are
somewhat altered in form, particularly designed to attain simplicity of construction
& cheapness of manufacture. The lateral guidance and support of the sticker a is
effected by the pin a traversing in the slot a therein, and said pin is affixed in the
damper body which carries the arm k¹ and head k. This body k² is carried
hinged to the arm k³ affixed to the flinge d².
In Figs. 8 8 & 9, the arrangements illustrated possess the advantage that by
affording facility for disconnecting the attachment of the butt flinge to the rail
supporting it, say by removing the screw d*, which screw is shewn in each
Figure, 8, 8 and 9, the damper and hammer parts may be removed in one.
advantage also attends the arrangement in Fig. 11 to be described.

The
In Fig. 10 the sticker a is laterally guided and supported by the hinged arm d4,
riding in the slot al in the sticker a. This armn d, is hinged at d to the rail d,
and carries fixed pendent therefrom the projection do, the front face of which is
clothed, and "sets off" against the hinged piece a carried by the sticker a.
extent of projection of this piece a" from the sticker is adjusted by screwing in, or
out, the screw pin a¹s from the sticker, and the damper wire j being connected to
and actuated by the end of the arm d', the damper is caused to act with increased
promptness; or, there may be instead an under damper, as in Fig. 8, the hinged
arm there shewn being hinged to the pendent arm de iu corresponding manner.
In case of it being desired to bave "outside" check, instead of "inside" check,
as shewn, it is simply necessary to mount the check head c³ on the arm d inter-
mediate of the sticker a and the front end of said arm, clothing the meeting surface
of check head and balance head c³ accordingly, as will be readily understood by
any practical maker of such parts.
In the modification shewn by Fig. 11, the pin d here shown, affords guidance
and lateral support to the sticker a, and this pin d is screwed into the head of the
hinged inclined set off piece de jointed at d to the rail d; the adjustable set off
pin a carrying the button a" serves, when screwed in, or out, to adjust the extent
of "set off," and in like manner by screwing the pin d' in, or out, of the piece de

The sticker a in this figure, and some of the other arrangements shewn, if
desired, is provided at its lower end with an adjustable screw extension, to facilitate
regulation of the length of the sticker.

piece c', which is carried by an arm, or extension, hinged to the butt
flinge d² rearward of the butt hinge, whereby I am enabled to dispense with a
separate flinge to connect this piece e, and also with the screw to attach it to the
hammer rail. The screw a¹0 forms an adjustable stop carried by the sticker for
the arm, or piece, c¹ to set off against. Or, the arm of the piece c* may be con-
tinued above the flinge d² and serve by engaging the tail (as k in Fig. 11) of a
damper body supported in a separate rail and flinge fixed above the rail d and in
like manner, so that the movement of the set off would actuate the damper.
In Fig. 13 I show another modification in which the "set off incline," or piece c
is slung, or hinged dependent from the same flinge as the butt, and this piece c¹ is
connected or hinged to the sticker a by the link, or flinge r. all is the set off
button on supporting screw pin a¹, whereby, great certainty of operation of parts
connected is secured.
Or, the link and the arm a³ (see Fig. 6) may be formed in one continuous
piece, the sticker being independent thereof, except where centred to this piece.
In Fig. 14 is shewn a modification of the arrangement indicated by Fig. 5, in
which the incline piece a¹ is made movable on the sticker a, by means of a hinge
joint a¹, the screw pin a serving to effect the adjustment; the "set off button" d³
is here shown fixed in the flinge d². In place of a prolonge rail and flinge
(carrying bottom arm 12 hinged to the sticker bottom), as shown in Fig. 1, I have
here shewn secured at foot of da bent, or angle, arm 14 carrying a flinge 1³, hinged
to the bottom of the sticker a, but dispensing with the prolonge rail and sup-
porting the series of arms from the hammer rail.
A guide pin m, indicated by dotted lines, projecting from the horizontal part of
arm may ride in a slot in the sticker a to guide and laterally support in lieu
of the forked check head shewn.
Or, the hinged arm d, shewn in Fig. 10, may be hinged at the base of the
pin c, Fig. 12, and in lieu thereof, and pass through and form the support for the
damper wire j, dispensing with or replacing the arm as of Figs. 1 and 2, the check
head g being supported from the sticker as shewn in Fig. 10.
In Fig. 15 I have indicated a modification of Fig. 5, in which I dispense with
the balance head and its shank and also with the check head and its wire, and I
attain the support and guidance of the sticker by means of a double ended link
piece n,
the spring o, supported from the front of the link n, serving by pressing on
the butt e to press the parts into proper relative position.
In Fig. 16 is shewn a modification of the invention, applied to an action having
a sticker with a "solid check" head. The flinge d² affixed on the hammer rail d
and carrying the hammer c, also carries the pendent arm k³, to which is hinged the
lever k, which is hinged to and supports the sticker a, and is also below hinged to
the prolonge p, which latter is by the hinged connection 1, 1, jointed to the
prolonge rail. The projection a from the sticker a, is pressed upwards by the
spring a, fitted between it and the lever k², and as the prolonge p rises, when lifted
by the end of the key lever b (see Fig. 1) it comes in contact with the adjustable
button q. The hammer butt c carries a metal balance head 8 of simple con-
struction, adapted to engage the front of the solid head of the sticker, or jack a.
In Fig. 17 is shewn a modification of the arrangements of the action shewn by
Figs. 13 and 15, in which the set off incline et is hinged to the hammer flinge d²
and carries a pin-c which passes through. a slot. in. the sticker a.; and the set off

page_text: button is held on the regulating pin a¹0* carried by the sticker_a.
The con-
nection of the sticker a and the hammer butt c is the same as in Fig. 15. The
lever, shewn in the preceding figure, may be connected, as shewn in Fig. 18,
to the prolonge p by means of a clothed, grooved, or slotted, piece t on the under-
side of the lever k², and a hinge pin on the head of the prolonge p.
The pin and regulating buttons thereon, hold this lever k² in correct relation
to the prolonge rail l, and this prolonge rail can be drawn towards the front or
pressed back, so as to carry the prolonges or lifters p forward, or rearward, on the
key levers b, and in the grooves t¹, to regulate the "touch" to make it lighter, or
heavier, either by means of a pedal, or a draw stop, as preferred.
This mode of regulating the strength of "touch is applicable to other like
arrangements where the prolonge p is connected, or operated, by a lever k² inter-
mediate of the same and of the sticker.
"
In Fig. 19 the butt spring is arranged as in Fig. 3, and the sticker
intermediate
lever, and prolonge p, much the same as in Fig. 16, but the prolonge rail is
dispensed with, and the arm k³ dependent from the hammer butt flinge d² is pro-
longed and centred to a connection to the prolonge p. The set off incline kis
mounted on the arm k³ and is engaged by the button a" of the set off pin a¹º,
screwed into the sticker a. is a spring borne by the lever k² and pressing on the
front of the sticker a.
10
Fig. 20 shews another modification of parts, somewhat different from Fig. 12, in
the form of the parts giving lateral support and guidance to the sticker or jack a.
This is effected by bent wire e passing through the slot al in the sticker a, and on
the rear end 18 of this wire is mounted the check c. This check c¹ can be regu-
lated, as regards its relative position to the hammer butt, by bending the wire c.
The set off a screwed into the sticker, engages the arm of the swinging piece,
centred to the butt flinge d² at 8, and the upper arm c¹ thereof may carry the
screwed pin c¹¹ carrying the button c which actuates the tail of the under damper
lever c centred at c¹ to the damper rail c¹³, cle being the under damper head.
j is the wire from the sticker arm actuating the over damper body' carrying
the damper arm 2 and over damper h. This body I hinge, as shewn, to the
rail c, and the over damper arm I support, as shewn, from the upper side of the
damper body h', as thereby I facilitate access to the means of connection of
the parts of the damper body to its supports, and ease of access to the damper-
head wire, or arm, to regulate the relation of the head to the string.
In case of an under damper not being desired, the parts of the under damper
action above the upper edge of the flinge d² might be dispensed with.
In like manner should the under-damper alone be desired to be used, and not
an over damper, the arm a projecting forwards from the sticker a may be
dispensed with and the wire and parts actuated by it may also be omitted or
removed.
By reason of the head of the screwed pin cl passing to the front of and through
the butt c, its regulation is much facilitated.
This method of supporting may be applied to the parts as shown in Figs. 8, 9,
10 and 11 by dispensing with the hammer rail d and prolonge rail l, and instead
screwing the flinges or supports to the pillar u, as indicated by the front view
Fig. 21, side view Fig. 22 and detail plan view Fig. 23, so that in repairing the
action, only that set of parts requiring attention need be removed, and this removal
only entails the removal of the screws connecting the particular pillar ụ to the base
or supporting rail s. The parts forming the "action" in the foregoing arrange-
ments, where the under damper is used, may be borne in the said manner on a
pillar u, one to each set or key.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1: The various combinations or arrangements of parts forming actions of

page_text: upright pianofortes substantially as and for the purposes set forth and shewn in the
accompanying drawings.
2: The construction of the metal balance head of one plain piece of metal as
shewn and described in respect of Figs. 1, 2, 3, 9, 11, 16, 18, 19 and 22 for upright
pianoforte actions.
