FIG. 7 is an enlarged detail fragmental view taken on line 7-7 of FIG. 6 showing the arrangement of the keys thereat, and

FIG. 8 is a sectional view enlarged, of the bass buttons shown on line 88 of FIG. 2.

Referring now more particularly to the drawings wherein like numbers refer to like parts throughout, there is provided a portable cabinet 10 provided with suitable rests or legs 11 and which as shown extend from the front 12 to the rear 13 of the bottom of the cabinet 10, to permit placing the cabinet on any suitable surface such as on a table, not shown. Said cabinet as shown is of the rectangular type; however, it may be of any suitable shape or outward form.

Said cabinet 10 has its front wall 12 provided with a plurality of longitudinal slits 14 extending part of the length of the face and a number of circular openings 15 as shown at the left side of the face thereof. These slits are provided merely for esthetic appearance and it is to be noted the slits 14 do however, extend through the wall 12 into the interior of cabinet 10 to permit some air to pass through from the interior of the cabinet. The top 16 of the cabinet is provided with a fixed top wall portion 16a attached to the rear wall 13 thereof and a movable flap portion 16b connected to said fixed top 16a by means 3,030,844 Patented Apr. 24, 1962 of a piano hinge which extends the full length of the top of said cabinet 10.

It will be noted that the cabinet at its front or face portion as shown in FIG. 2, when the top lid 16b is open has a keyboard 17 consisting of keys 18 and 19 representing sharps and flats respectively, and a bass board 20 with bass buttons 21 which are set in groups as shown to obtain the desired harmony when playing the instrument. As shown said keys .are each provided with a rearwardly extending portion 22 the end of each of which is provided with a felt closure piece 23 adapted to fit over and normally cover openings 24 in the top board 25 of inner compartment 26 as shown in FIG. 4.

It is to be noted that the cabinet 10 contains said closed compartment 26 with its upper or top board 25 containing a series of openings 24 for each of the keys of keyboard 17. It is to be further noted that said compartment is completely sealed and that air therein cannot readily escape except through said openings and also through the area of the openings in the bass portion as well. Furthermore, said compartment 26 contains a reed plate 27 mounted on depending members 30 and 31 and provided with individual passageways 28 each covered by a reed 29. As shown, the reed plate is inside the compartment, and it is only when keys on the keyboard are operated that air escapes through the reed plate vibrating the respective reeds to obtain the desired tone or musical effect.

As shown in FIG. 8, the bass buttons 21 on keyboard 20 terminate the vertically slidable rods 30 which have transverse projections 9. Crank arms 31 are engaged at one end thereof by said projections for rotation upon depression of buttons 21, and also comprise central pivot rod portions as seen in section at the opposite extremity thereof, which are thus journalled for rotation in con ventional means not shown. They also comprise at the other extremity thereof, valve lifting fingers 9a located in different vertical planes than those of their corresponding arms 31, and which are rotatable integrally therewith, in engagement with links such as 33 on the valves 34 to lift said valves from their seats by swinging them outward therefrom on the resiliently swingable arms 32 to which said valves are attached. Valves 34 are thus enabled to permit air passage therethrough from the sealed compartment 26 to actuate the respective reeds 35, as shown in FIG. 8 of the drawings. These bass key buttons may be operated singly or severally to combine with the playing of the keys 18 and/ or 19.

It will be further noted that each of said keys 18 or 19 as shown in FIGS. 5, 6 and 7 is provided on its under side 36a with a spring 36 fixed to the exterior of the top wall 25 of inner compartment for normally keeping the end portion 22 depressed so that the felt piece 23 normally covers the openings 24 except when the key is actuated. Also the underside 36a of the key is provided with a cross pivot of dowel 37 adapted to fit in a cross recess 38 in parallel side plates 39 which are fixedly located on each side of the under portion of the key as more clearly shown in FIGS. 5 and 6.

Furthermore, the top plate or board 25 of the compartment is provided at its top face with a pair of felted stop members 40 and 41 to soften the downward thrust of the finger pressing portion of the key 18 or 19. Also as clearly shown in FIGS. 4 and 6 there are provided members 30 and 31 onto which is mounted said reed plate 27. Said members are coextensive with the length of the keyboard 17 and provide a sufiiciently large opening for air or wind to pass through the different reed openings or passages 28 when one or more of the keys 18 and 19 are depressed or into the chamber 44 and pass therethrough when any of the buttons 21 are depressed to open valves 34 of reeds 35.

It will be noted that compartment 26 is sealed and is provided with air space for the reed plate and also an opening 45 at the floor board 46 of the compartment.

Mounted over said opening and fixed to said floorboard 46 there is an impeller 47 with a motor 50 mounted inside a hollow funnel or truncated section 48 onto which theimpeller 47 is axially mounted as shown. Said motor 50 is connected with a source of electricity by means of aconductor cord 51 controlled by a switch 52 shut off when cover is down on top plate, and when operated causes the impeller to build air pressure in compartment 26 for the continuous and proper operation of the instrument.

It will be noted that as stated when the motor and impeller "are operating, the pressure of the air in the compartment builds up and on depression of keys 18 and/or 19, the air escapes through the reed plate 27 to produce the desired music. In other words, there is always available a supply of air under pressure to insure suflicient air to permit easy and rapid playing of music according to the keys and chord selected. The instrument as constructed gives a complete chromatic run of music. The sealed air compartment beneath the key and bass board section permits a continuous supply of air under pressure to facilitate smooth playing with the instrument. Also, there are no normal air outlets in the compartment except through the valves and reed plates. Furthermore, it will be noted that as shown in FIG. 8 there are provided rows of transverse crankshafts terminating the crank arms 31 at their left hand ends and at right angles thereto which operate valves 34 the same as the others on the keyboard. However, there are varying combinations of valves being lifted when the buttons 21 are depressed so that sometimes both valves 34 are lifted by the same button 21.

While a preferred embodiment of the invention has been herein illustrated and described, it is to be understood that changes or modifications as to form, structure, arrangement of parts auduse of materials may be made without departing from the spirit and scope of the invention as claimed.
