`I irn/'entclnn relates,toaccordions ofthtype ncomprisingv, valves ,being ...fastened :underneath said panel.U The vvalves. `are `controlled I.by` rneans `.of,.levers by av keyboard..y arranged vinproximity .of therear Vvvall,..\vhiclr1 keyboard 4may be a pushbutton or piano-sty1e,keyboard. ....SIhe .principal l objectcof the ./invention vis an .boarda Accordingtofthe invention the arrangement is @of sucha nature that .the end .of V.the panel facing .I the rear .wall of .thecasing reaches .at least-f up .to thebellows frame,.and`that .thelowernend of the keyboardis arranged inlthespacebetween the lrear wall of the accordion casing and the said part of the panel. i

OwingV tofthe. deep position of the lower end of, the keyboard within theaccordion casing,V at- AVAtained Vthrough said arrangement, thekeyboard ,(wdtnis. smaller thantha'tpf the`,.accordions hitherto known, and the decrease inheightlhas the,l advantage of easierf'and more :con nient playing because of theshorter distance b 4ween ff-athe players hands.` In vaddition, thelside the 1,accordion casing facing the, .'player is vle`s's""`l1igh Iand fits well to the playersjbody. n. u

Another object of *the present inveitinthe manner in whichthe room for the arrangement ofthe lower end of the keyboard or themecha- I Iiismfor-contrgllinatbe register slidesiecreaed `one form yef realisation y.of the invention the ,panellmounts from underneath the keyboard in a fslanting ,line towardsithe front vwa'llof the V.accordion casing.v It may ascend uniformly until it reaches thefrontend` o f.theaccordioncasing or it may ,.fQrm an angle with the portionrarrying the reed blocks. In the latter case the portion of the panel arranged underneath the keyboard mounts in a slanting line up to the reed blocks, and that portion of the panel which carries the said reed blocks forms an angle with the slantingly ascending portion of the said panel. Y

The angular portion of the panel may also be so constructed that it forms a trough into which the lower end of the keyboard reaches down. This arrangement has the advantage that the keyboard can be made to reach especially deep into the accordion casing.

It is also possible according to the present invennen that thetrugh is` formed byftl angular portion of tle'panel arranged below -'the keyboard together with the lower end of tliekey- 5V; board support, fand with a further realisation of the,invention the space, to receive kthe lower L end of the keyboard isH formed by the panel alone. y

Another roinect ofthe present inventi onis^ that i the I:portion ofthe cover which overlays the reed gck, rows in the proximity of the accordion casing rear wall is at right, or nearly right angle )to thekeyboard surface. ...advantageous arrangement of the treble key- The invention .willbe more 'easily"y understood tion and in which:l

.Abellows frame l0 carrying` the Abellows II'is ar- A.ranged atthe lower .edges of thecasing I. o

According to the invention the end of the panel 3 facing the rear wall I2 of the accordion casing I reaches at least up to the bellows frame I0. The end may be mounted directly on the frame I0 (Figs. 1, 4 and 5), or fastened some distance above it (Fig. 2), or penetrate into it (Fig. 3).

In the arrangement according to Fig. 1 the panel 3 mounts in a continuously slanting line from the bellows frame II] to the front wall I3 of the accordion casing I. The keyboard support I4 rests on the panel 3, or on an intermediate block I5. The keyboard support I4 is held *d by a prop I6 glued between the rear of the said keyboard support I4 and the rear wall I2 of the accordion casing I.

In the arrangement according to Fig, 2 the panel 3 has an angular form. The panel 3 does not entirely reach up to the bellows frame I0 but leaves a small clearance I'I and is fastened to the rear wall I2 of the accordion casing I.

At rst the panel mounts in a slanting line and the portion I8 of the panel 3 carrying the reed blocks 2 is arranged at a certain angle to the slanting portion I9 of said panel, e. g. in such a way that said portion I8 runs parallel to the plane of the bellows frame I Il.

The slanting portion I9 of the panel 3 is preferably reinforced because of the keyboard support I4, e. g. by a block 29 (shown by dotted lines) glued to the said portion from underneath.

Fig. 3 shows an arrangement of the invention according to which the space to receive the lower end of the keyboard is of a trough-like shape. In

this arrangement of the invention the slanting portion of the panel 3 and the lower end of the keyboard support I4 form the trough 2|. The angular portion extends deep enough to allow the trough 2| to penetrate into the bellows frame I0, whereby the levers 22 of the keyboard and 'the levers E controlling the valves 'I are mounted and jointed at the bottom of the trough. l

In this arrangement the angular portion of the panel has the form of a right, or almost right angle 23, whose free end is glued to the lower end of the keyboard support I4, the latter being held by a prop IS glued between said keyboard support I4 and rear wall I2 of the accordion casing I.

The arrangement according to Fig. 4 also has a trough-like space 2l in which the lower end of the keyboard, formed in this case by the keys 5, is arranged. The said trough 2! is formed by the angular end of the panel 3 and by the rear wall of the accordion casing I which wall in this case serves as keyboard support. The end 24 of the angular portion 23 is fastened between rear wall I2 of accordion casing I and bellows frame IIJ.

The mechanism 30 for the register slides 25 which are controlled by the key 26 and the linkage 21 are preferably arranged in the trough.

Fig. 5 also shows a trough-shaped space 2I serving to receive the lower end of the keyboard. In this type the trough 2l is inside the bellows frame I0, and the keys are arranged as low as possible` The end of the angular portion 23 is U-shaped and its end portion 24 is fastened between the r-ear wall oi accordion casing I and the bellows frame I0.

In all modes of realisation of the present invention the portion 29 of the cover 9, overlaying the reed block rows in the proximity of the rear wall I2 of the accordion casing I, is at a right, or almost right angle to the keyboard surface.

What I claim is:

1. An accordion comprising two casings and a bellows connected with its ends to said casings, one of the casings comprising a bellows frame,

a rear wall and a front wall both mounted on said bellows frame, a cover, a panel arranged between the rear wall and the froni-l wall within said cover, reed blocks arranged underneath said panel, a keyboard arranged in proximity of said rear wall with the rear end of the keyboard arranged between the rear wall and the reed blocks, said reed blocks including valves being adapted to be controlled by said keyboard, at least one part of said panel being arranged at an acute angle relative to the plane of the bellows frame, the end portion of the panel facing the rear wall vbeing arranged to extend substantially to the plane of the bellows frame where the bellows is secured, the keyboard being arranged approximately perpendicularly to that part of the panel which is arranged at an acute angle relative to the plane of the bellows frame, and the part of the panel which is spaced the greatest distance from the keyboard being for the most part spaced from the plane of the bellows frame, a part of one of said casings on which the keyboard is supported having means which include pivots for the keys of the keyboard, and a trough comprising a part of the rear wall and an extensionof the panel provided for receiving the lower end of the keyboard, the walls of said trough including the portion of the panel arranged under the keyboard and the lower end of said panel supporting the keyboard with the rear wall of the casing being integral with the said part of the rear wall forming a part of the trough.

2. An accordion according to claim 1, in which the rear end of the keyboard is arranged in said trough, and in which at least one register slide is provided between said reed blocks and said valves, a mechanism in the trough for controlling said register slide, a key for controlling said mechanism, and a linkage connecting said lastmentioned key with said mechanism.
