1 Claim.
My invention relates to improvements in accordions and has as one of the principal objects thereof the provision of means for automatically supplying the accordion with air for operating the reeds.
Another object of my invention is to provide means of the above described character adapted to be installed within an accordion of ordinary construction and which means includes an auxiliary power operated bellows so constructed and arranged as to be inserted within the bellows of the accordion.
An important object of my invention is to provide a device of the character described which is simple in construction, durable in use, efficient in operation and economical in manufacture.
Other objects and advantages will be apparent from the following description, appended claim and annexed drawings.
Referring to the drawings wherein like reference characters designate like parts throughout the several views:
Figure l is a rear elevation of an accordion, with the rear and front walls of the rear reed chamber and the reeds removed, and illustrating my invention as applied thereto.
Figure 2 is a sectional view, partly in elevation, taken on the line 22 of Figure 1.
In practising my invention, as illustrated in the drawings, I provide an accordion 4 having the usual treble and bass reed chambers 5 and 6 respectively and which chambers contain the usual reeds (not shown). Prejacent the chamber 5, the accordion is provided with the usual key board 8, the latter being connected to the front wall 9 of the chamber 5. The chamber 5 is provided with a rear wall l having secured thereto, adjacent one side thereof, a rearwardly extending bracket I l for a purpose hereinafter set forth. The chamber 6, is provided with front and rear walls l2 and I3 respectively and with said rear wall constituting a closure plate readily removable from the side and end walls of the chamber 6 whereby ready access may be had to the chamber 6.
The rear wall ll) of the chamber is provided with an opening 14 effecting communication between the chamber 5 and the interior of an auxiliary bellows l5, the latter having its front fixed to the rear face of the wall I0. The rear end of the bellows I5 is provided with a plate l5 having secured to one side thereof a U-shaped channel member ll slidably receiving a pin l8 mounted on a disk l9 adjacent the periphery of the latter. The disk I9 is provided with a centrally disposed hub fixed to a shaft 20, the latter being rotatably journaled in a bearing 2| carried on a rear end of the bracket II. Fixed to the shaft 20, between the disk I9 and bearing 2|, is a sprocket 22 connected to a similar sprocket 23 by means of a chain 24.
As clearly illustrated in Figure 1 of the drawings, the bottom and one of the side walls of the chamber 6 has secured thereto a pair of bearings 25 the latter hawng journaled therein a shaft 26. One end of the shaft 26 has fixed thereto the sprocket 23 while the other end of said shaft has keyed thereon, for rotation therewith, a gear 2'! meshing with a gear 28 fixed to the armature shaft 29 of an electric motor 30, the latter being mounted on the oppositely disposed side wall of the chamber 6. An electrical receptacle 3! is arranged within the last mentioned side wall and has electrically connected thereto electric wiring 32 leading to the motor 30. The receptacle 3| receives therein, for electrical contact therewith, the prongs of a detachable electric plug 32. The plug 32 has connected to its prongs input wires 33 connected to a source of electrical energy for operating the motor in the usual manner.
The side of the plate l6, oppositely disposed from the side on which the member I1 is fixed, has extending therefrom a pin 34 normally seated within an opening 35 formed in the rear end of an arm 36. The front end section of the arm 36 is pivotally connected to a bracket 31 carried by the wall It adjacent the bellows l5. The front end of the arm 36 is pivotally connected to the inner end of a plunger 38 extending through the adjacent side wall of the chamber 5. The outer end of the plunger 38 is provided with a finger piece 35 for operating said plunger inwardly and causing the rear end of the arm 36 to be disposed out of engagement with the pin 34. The inner end of the plunger 38 has sleeved thereon a coil spring 40 having one end fixed to the adjacent side wall of the chamber 5 and the opposite end connected to t e r0nt End Of the arm 36 whereby to normally maintain the rear endof said arm in engagement with the pin 34 thus maintaining the adjacent side of the bellows 15 in a fixed position with respect to the wall I4. The walls 9 and I2 of the chambers 6 and l are provided with inlet and outlet valves 4! and 42 respectively whereby air may be introduced into said chambers and exhausted therefrom should the pressure therein become too great.
Obviously, upon operation of the motor 30, the
disk [9 is rotated to effect reciprocation of the adjacent end of the bellows 15, the pin 34 disposed within the slot 35 of the arm 36 serving as a pivot for the opposite end of the bellows 15 thereby causing air to be pumped from said bellows I5 into the chamber 5 through the opening Hi.
When it is desired to operate the accordion in the ordinary manner, the arm 36 is disconnected from the pin 34 through the medium of the plunger 38 and the plug 32 detached from the receptacle 3|. When the parts are thus arranged, the left hand is disposed through the strap 43 attached to the plate l3 and the accordion operated in the usual manner through the medium of the bellows 1.
Without further elaboration the foregoing will so fully explain the invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service. Moreover, it is not indispensable that all the features of the invention be used conjointly since they may be employed advantageously in various combinations and sub-combinations.
It is obvious that the invention is not confined to the herein described use therefor as it may be utilized for any purpose to which it is adaptable. It is therefore to be understood that the invention is not limited to the specific construction as illustrated and described as the same is only illustrative of the principles of operation, which are capable of extended application in various forms, and that the invention comprehends all construction within the scope of the appended claim.
What I claim is:
A device of the character described, comprising, an auxiliary bellows adapted to be carried by the rear wall of the front reed chamber and within the main lbellows of an accordion for supplying said reed chamber with air through an opening in said rear wall, eccentric mechanism connected to said auxiliary bellows for operating the latter, a motor adapted to be mounted in the rear reed chamber of said accordion, means connecting said motor to said mechanism for operating the latter, and means detachably connected to said auxiliary bellows and operable for precluding operation of said auxiliary bellows during operation of said accordion by said main bellows.
