. This invention-relates to certain improvements .on
the organ-improvemeut f orwhieh Let-ters Patent, No. 54,603, were granted yto nie on the 8th dayiof May,
The present-invention. has for vits .object to simplify the devices onthe composition-board'referred to in the aforesaid Letters Patent, as well as the pneumatic lever, and to provide a reliable and practicable tremnlant pneumatic lever, and a reversible coupler for the keyboards.
-The connection between the slides which are acted .upon by the buttons or finger-pieces and the oscillating valves of the pneumatic levers that actuate the drawstops, is in this apparatus produced by a series of oscillating rockers, therebyfdoing" away with the elbowcranks and their numerous pivots,`and 'consequently with a great amount of friction.
rlhe valves of the pneumatic levels are made oscillating, and not reciprocating, and can thereby be operated with greater ease, as they are not vmoved against .a direct pressure of air.
The reversible coupler is so arranged that it is reversed by eveiy mot-ion of a button, whatever be its position.
The tremulant'pneumatic lever which is interposed in a suitable position between the wind-trunk and the pipes has its two movable side-pieces so connected that when one side is inflated it will automatically be cut ofl from the air-supply, and the other side connected with thesame, whereby reciproca-ting or other motion is imparted to the draw-stops or other devices for producing a tremulo or other vibrating action.
A A' arei the two key-boards of an organ, fitted into the frame B. 1
C, C, G2, C3, &c., are the buttons or finger-pieces for operating the pneumatic levers D.
Of' the lat-ter, but one is representedin the drawing,
although one is to be provided for and connected with every draw-stop E, by means of rods ab, or their equiv alents, as shown -in tig. l.
The buttons C, C1, G2, die., are connected, by rods c c, with slides F, F1, F", Ste., respectively, each slide having a number of projecting pins, d d.
G, G, G, &c., are a. number of transverse rockshafts, hung iu the composition-frame H, one for each pneumatic .lever and draw-stop.
Each rock-shaft G, G, 3&0., has as many projecting ears e e as there are slides 15",15", &c. Every slide, with the exception of' the irst.one, F,
.which sets all the draw-stops in action, isv at its outer end conuected, by means of pivoted cross-pieces f, with reverse slides I, so that when a button is touched to push one slide out, the reverse slide connectedwith the same will be drawn in. 11
The 'reverseslides have pins g g where their operating-slides have none, and rice versa.
Vheh a slide is pushed by its button, it will, with its' stops d, strike oneor more of the Aears of the rockers 4 G, Gl, 85e., and will tum them to open the valves of the pneumatic levels connected with them, while its re verse slide will actuate the remaining rockers in the opposite direction, and will thereby reverse the valves oftheir levers.
A .s the pins in the various' slides are diiierently disposed, all desi'red combinations can be produced by pushing the desired buttons.
The valveJ is arranged in the air-channel K, which carries the air from the trunk to the pneumatic levei' D, and is of conical form.
An arm, 71, on it, is, by an adjustable rod, fi, connected with a crank of the. rocker pertaining to such valve.
Then the valve is opened by the aforesaid means, the air is let into the leverfand the same has thereby one department inflated to pull the thaw-stop.
lVhen the valve is moved in the opposite direction by the action of the reverse slide, the other side of the lever isinfiated, and the draw-stop moved in the opposite. direction The valve J, which is more fully shown in figs. 5, 6,
and 7, is, as aibremeutioncd, ot` conical form, and is .held against its seat by a spring, j.
Itis made to work tight or loose, by means of' an adjusting-screw, I, which is either put through the valve, as in iig. 6, or through the scat, as in lig. 7,'and
which serves tohold the'valve asuitablc distance away from its seat.
The slides F, &c.', instead of being connected with reverse slides, as aforesaid, canbe slotted, as in iig. 8, to embrace the rock-shafts G, G, 85o., in which case slides have pins al g', respectively, above and below the rock-shafts, to act. on the ears of the latter, in opposite direct-ions, such ears projecting from both sides of the .rock-shafts, as shown.
By this arrangement, the amount of friction in operating the pneumatic levers is still more reduced.-
Tle coupler, for connecting and disconnecting the key-boards of the organ, is operated by a rod, which is shown by dotted lines in tig. 3, and which is connected'with a lever, an, thatjs pivoted to the frame of the compositiou-movement.
From the lever m. projects a wed ge-shaped bar, n., as in fig. 3. v
The reversing-button o is attached to a slide, L, which is at its back end pivoted to a pivot-ed lever, M.
A spring, q, draws the button out.
K A bar, N, is pivoted to the lever H, and is, by a spring, lr, retained in a certain position, and still permit-ted to swing to the right a'nd left.
'\Vhen the button o is pushed, it pushes the bar N .against the wedge n, on one side of vits point, and thereby swingsthe lever m., so as tomove the coupler in one direction.
The spring q will, on account oi' the changed posi- A ,"ton of the wedge, come against the vopposite side of f the wedge, and will thereby reverse the position ofthe couplerx rlhus, at every motion of the button o, the
coupler will be revelsed,
,y The pneumatic lever aboveV described is either as Vmentioned in my aforesaid Letters Patent, or it may have' its sides iixed and its middle portion movable, as indicated in iig. 1.
A pneumatic lever, 1).', for producing a tremolo, is
" shown in tig. 4.
Itisthe same as that above described, and provided with avalve, J, in its middle stem s, and with a rod, t'. Gu the face of its stock is pivoted an'ancl'ior, t,
1 which plays over an arm, u, that projects from the valve. v
A'.lhe -two movable side-plates V V of the lever are connected with each other hy a bar, XV, as in fig. 6, so
. that when one is iniiated, the'other must be emptied,
and 'vice yversa.
The anchor is connected with a. spring, y, which tends to pull it up to either side after ithas passed the centre.
By means of a rod, X, the anchor is connected with one side-plate V.
iVhen the V-side is inflated, it draws, by the rod X, the anchor toward it, and the anchor, during this motion, swings the arm u of the valve, thereby turning the valve and letting the air into the V'eside of the lever.
XVhenI that side is being iUHated, it draws the side V toward the middle end, and the rod X pushes the anchor, so as to swing the same andturn the valve,
and thus the air blown through this lever produces a constant vibration of its sides, and a consequent motion of the tremolo or other devices.
Having thus described my invention,- .l What I claim as new, and desire to secure by Letters Patent, is-
1. The rock-shafts G, G1, &c connected with the pneumatic levers, and provided with projecting stops 'c e, so thatv they may be worked by the slides F, 1.1,
&c., substantially as herein shown and described. .v.. The slides F1, F2, Sac., for` operatingthe pneu#l matic levers, when connected with 4the reverse slides I I, substantially as and for the purpose herein shown 'and described.
3. rlhe slides E11", 85e., when slotted and provided with two sets of pins, d' g, to operate directly the pneumatic levers,substantially. as herein shown and described.
4. The valve J of the pneumatic'lever, when held i against its seat by a spring, 7', and when adjustable on the seat by the screw '1, substantially as aud for the purpose herein'shown and described.
5. The reversible coupler, consisting of the-lever fm,
'wedge n," slide L, lever M, and bar-N, all combined Aand operating substantially as and for the purpose herein shown and described.
(i. The tremolo pneumatic lever D', provided with the anchor t, rod X, spring y, and a-rm u, on the valve, all arranged and operating vsubstantially as herein.
shown and described.
