4 Claims.

This invention relates to accordions and has for one of its objects the provision of such a musical instrument in which the keys control a plurality of valves by means of a plurality of rods connected to each of the keys, each of the said rods carrying at its end a cover overlying a valve opening located at different portions of the instrument.

Another object of the invention is to produce an accordion in which the keys when actuated will simultaneously operate a plurality of valves in communication with reed chambers located in diiierent Zones of the accordion.

A further object of the invention is to provide an accordion with reed blocks at the front of the accordion, the reeds of which are in communication with a sound chamber formed by the accordion cover, the said accordion also having a plurality of reed blocks at the rear of the instru- 20 ment, the reeds of which are in communication with a sound chamber extending the entire length of accordion and in open communication with the aforementioned chamber, the reeds of the last named blocks extending laterally.

A still further object of the invention is to provide an accordion which is capable of producing a sound or tone in simulation of an organ.

Another object is to produce a device of the character described in which the maximum sim- 30 plicity of construction and operation is secured.

Other objects and advantages will appear as the nature of the improvements is better understood, the invention consisting substantially in the novel arrangement and co -relation of parts herein fully described and illustrated in the accompanying drawings, wherein similar reference characters are used to describe corresponding parts throughout the several views, and then finally pointed out and specifically defined and indicated in the appended claims.

The disclosure made the basis of exemplifying the present inventive concept suggests a practical embodiment thereof, but the invention is not to be restricted to the exact details of this disclosure, and the latter, therefore, is to be understood from an illustrative, rather than a restrictive standpoint.

The inventive idea involved is capable of receiving a variety of mechanical expressions, one of which, for the purpose of illustration, is shown in the accompanying drawings, in which Figure 1 is a fragmental perspective view of my improved accordion with a portion thereof broken away for the sake of clarity.

Fig. 2 is a sectional view taken on line 2-a Fig. 1.

Fig. 3 is a bottom plan view of tr showing the arrangement of the blocks.

Fig. i is a fragmental plan ViCW partly in section of the right-hand end of the acco Fig. 5 is a iragmental sectional vr line 55 Fig. 2, and

Fig. 6 is a fragmental top p an view fied form of the front portion of the a Referring now to the drawings in detail, 5 dicates a housing in communication usual bellows ii. A keyboard i2 lo the top of the housing ill, keyboard seine provided with keys i3 and iii pivoted respectively at l5 and 56. The said lteys are each provided with a. tension spring ii one end of whi cured to its respective key and the oppo is in contact with the key-board has The keys [3 are each provided with a arm 20 having a valve cover which normally overlies and closes a valve opening in a wall or plate 22 at the front of the accordion, and a second rod 23 provided with a valve cover covering a plurality of valve openings in a Wall or plate 25 located approximately midway be tween the housing front and rear walls 52? and 28 respectively. The keys i i are each provided with a. rod 39 having a valve cover 83 normally closing a valve opening in the plate of the said keys M being further provided l a rod 33 having a valve cover normally COVQ: J.{Z' a plurality of valve opemngs 35 in. the plate Eli.

Directly below the wall 22 there are provided 35 two reed blocks 35 and 35 having sets or banks of reed chambers 36 and ill respectively. Reeds 38 are secured to plates 39 which close the inner side of the reed chambers 35 and plates 39 provided with reeds 40 which close the reed chambers 37. Directly behind or to the rear of the wall 26 there is provided a chamber a l in which are removably mounted lower and upper reed blocks 42 and 43 respectively. The block 42 is provided with banks or sets of reed chambers i l 45 and 45 which are in communication with the valve openings 25, the valve chambers 44 being provided with reeds 46 and the reed chambers 45 with reeds 41. The block 43 is subdivided into sets of reed chambers 48 and 49 in communication with the valve openings 35 and each of the said reed chambers is provided with reeds 553 and cordion reed 3 in-- the dat wall 26 and the rear wall 53 of 37, the said sound chamber horn-shaped in cross section and is open at the top thereof, said opening leading into the interior of a cover 54 which forms a sound merging chamber 55 common to all of the reed banks.

The reed blocks t2 and 43 are each provided at one end (see Fig. 3) with an extension 56 and at the opposite end with a slidable wedge 51. The extension 56 normally engages a block 58 and the wedge 57 engages a tapered strip 59. The wedges 51 are normally held in place by thumb screws Bil which when slightly unscrewed loosen the wedges sufiiciently so that they may be slid out of engagement with the strip 59 thus enabling the reed blocks to be removed when occasion arises.

I have found that the combination of oboe and clarinet tones produce an organ effect, and inasmuch as I desire an accordion that will produce tones or sounds in simulation of an organ, the reeds 38 and it are of such nature that they will produce an oboe sound and the reeds on the reed blocks 32 and 43 are adapted to produce base clarinet tones which when combined with the oboe tones of the reeds 38 and 40 will produce the desired organ effect.

It will be seen that when any of the keys of the keyboard are actuated two valve covers will be raised thus sounding base clarinet reeds of the lower reed block All? and oboe reeds 3B of the foremost reed block 35 or base clarinet reeds 5i! and 59 of the upper reed block 33 and reeds of the reed block 35*, which sounds will combine and be amplified in the sound chamber 55 to produce an organ effect.

In Fig. 6 I have shown a modified form of the invention wherein instead of a single reed block 35 I utilize two such blocks the reed chambers of which are in communication with two valve openings 22 and are covered by a single cover Zi on the rods 20 thus enhancing the tone qualities and volume of any given notes.

I desire it understood that I do not limit myself to the use of sound devices that will produce the oboe and base clarinet tones as any desired combination of sound-producing devices may be used to produce a given or desired tone effect.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In an accordion, a housing having a cover formed with a sound outlet opening, a bank of reed chambers in said housing, a second bank of reed chambers in said housing, said banks of reed chambers being spaced from the cover of the housing to provide a sound merging chamber and being spaced from each other to provide a sound chamber leading from the sound merging chamber, playing keys, an arm extending from each key towards one of the first bank of reed chambers, a second arm extending from each key towards one of the second bank of reed chambers, and a valve cover on each arm controlling their respective reed chambers, one bank of reed chambers extending in a vertical plane across the accordion with the outlets of its chambers opening into the sound merging chamber and the other bank of reed chambers extending in a horizontal plane with the outlets of its chambers opening into the sound chamber.
