reedcarrying heads of the. accordion and supplemental to the bellows. i i

In the use .offaccordiotns, considerable difficulty arises because of the tendency for one headof the accordion, and usually the headin which the bass reeds are carried, to drop because of its weight.

-It is theprincipal objectof the present invention to provide an improved interconnection betweenfthe heads of an accordion and rearwardly disposed with respect to the bellows so as to avoid undesired interference with the bellows.

It is a further object of the present inventionto' provide an interconnection between the heads of an accordion having integral brackets which can be quickly and easily attached to accordions now in use, and by which the action of the accordion and the control thereof will be improved.

It is a further object of the present invention to provide an interconnectionbetween the heads of an accordion having integral end brackets eachof such can be readily attachedto one of the heads, anexpansible parallelmotion connector therebetween ,and readilyfinsertable' rods. for

securing the connectoriat its ends to the endbracket.

It is a further object .ocfthe :present invention to provide an interconnection between. the heads of an accordion which is simple in construction, reliable inits action, which will beief fectivel for maintaining theheads of the accordion for controlled movement with respect to each other and which will prevent excessive separation of the heads in 1*;- 11' {It-1s a iurther object of the present invention to provide an interconnection between the heads of an accordion for effecting a parallel motion actuation of the heads in use while permitting vertical swinging of the heads, and

which is adapted for; use with various sizes and models of a i r id lmw i q.

vQIt is a iurthi 1- object of the present invention to provide an interconnection between the heads; of an accordion which is freelymovablelsoiasnot to inter fere with the free movement of the heads of the accordion.

It is a further object of the invention to provide an improved interconnection between the heads of an accordion which will. support the accordion with the bellows; in spaced relation to thebody of the player and which is free from any tendency tocatehpon orgrip'the bellows, or thecushioningpad which is frequently interposedbetween one of the'heads and the body of the player, or the clothing of'the player. r i

iIt is la. {further object of the present invention to provide a simple form of interconnection between the heads of; an

accordion for maintaining a controlled relative movement thereof and which can be easily mounted in position by relativelyinexperienced persons. Y

Other objects and advantageous features of the invention will be apparent from the description and claims;

..The nature and characteristiefeatures of the invention I will be more readily understood from the following de- FIG. 6 is a iragmentary sectional view taken approximately on theline 6 6.of FIG. 5.

A nrain bracket 20 is provided having a vertically extending bracket plate portion 21 and integral upper and lower mounting arms- 22 and 23 shaped as illustrated particularly in FIGS. 3 and 5, to spacethe bracket plate portion 21 from the rear wall 14 of the head 10 and at an angle with respect thereto. The arms 21 land 22 are 30 preferably has ahead 31 with a knurled portion 32 secured. to the head 10 by a plurality of screws 24 at spaced locations and extending therethrough into the Wall 14."

The bracket 20 has extending horizontally from the,

bracket plate portion 2 1, a pair of integral relatively closely spaced; lugs 26 and 27, an intermediate integral".

a The bracket 20 can be made of any desired material which is light in e weight and strongjaluminum being particularly suitable.

An upper hinge plate '36 is provided and is freely rotat-ably mounted on the rod '30, between the lugs 26 and 27, and a lowerhinge plate 37 is provided, also freely pivotally mounted on the rod 30. The upper hinge plate 36 is restrained against vertical movement by the lugs 26 and 27 while being swinga'ble with respect to the rod 30. "The lower hinge plate 37 is freely swingable on the rod- 30 and is slidably movable vertically between the limitpositions permitted by the lugs 28 and 29.

'- The hinge'plaltes 36 and 37, as shown particularly in FIG. 6 for the hinge plate 37, are preferably provided with hearing sleeve inserts 40 of lanti-frictionmaterial, such as Teflon, nylon or the like, which are not affected by damp weather or weather changes A second main bracket 4 5 is provided having a verticall extending bracket pl -ate portion 46 and integral upper and lower mounting arms 47 and 48 extending frorirthe plate portion 46- :a'nd' shaped as illustrated particularly iii FIGSl l to 4.

The nut 57 is also knurled as at 59 for facility of application. 7

The bracket 45' can be made of any desired material but is preferably of the same material as the bracket 20. Anupper hinge plate '60 is provided and is freely rotatably mounted on the rod 54, between the lugs "50 and, '51, land a lower hinge plate 61 is provided, also freely pivotally mounted on the rod '54. The upper hinge plate i 6t) is restrained against vertical movement by the lugs 50 and 51 while being'fswingable on-the rod 54. The

lower hinge plate 61 is freely swinga-ble on the rod 54 land slida'bly movable vertically between the limit positions permitted by the lugs 52 and'53. f

The binge plates 36 and 37 have bifurcated connecting portions '62 and 63 extending therefrom oifset with respect of the rod *30, the head 11 the player is required.

The head 11 may be freely and easily movedtowards. and away from the head in the playing of the accor-' dish, and. is supported and maintained at-the same level by the linkage provided on the rear of the accordion. "The linkage is restrained from contact or engagement with the bellows in the. more or less separated condition of the V heads 10 and llby the'engagernentot the hinge plate the stop post 66. I

z The freely movable pivotal mounting provided between the. links 69 and 71, between the links fi and 7 1 and the t hinge plates 36,37, 60 and 61 and between these hingef plates, and the rods 30 and 54provides a substantially hic tion free-connecting and supporting'st-ructure s-o'that no additional burden is placed on the player, the heads '10 and" l1 being freely' movable towardsand away from each other, and swingablexvertically' but maintained in'level 7 condition. A very rapidor quivering efiect'can thus be to a vertical plane through the longitudinal axis of the rod 7 36 away from the rear wall 114 of the head 10.-

The hinge plates 60 and 61 have bifurcated connecting portions 64 and 65 extending therefrom and ofiset with respect to a vertical plane through the longitudinal axis of the tod 54 forwardly towards-the bead 11.: The upper binge plate 6b is limited in its movement towards the bead 11 by a stop post 66 carried. by the bracket I portion 46.

pivotally connected at their opposite sections and intermediate their ends are connected by I pivot pins, 77 in antifriction bearings78. The connection of the links 69 land 71 at their ends to the rods 30 and Stand intermediate their ends provides a parallel motion connection between the beads 10 and 11," with the upper hinge plates 36 and 60 restrained from vertical movement by their respective positioning between the lugs 2,6 and-27 and the lugs 50 and 51 with the lower hinge plates 37 and 61 free to slide on the rods 30 and 54 in the locations between the lugs 28 and 29 and the lugs 52 and 53. The binge plates 36, 37, 60 and =61 and the links-69 and 71 preferably have their edges rounded or shaped to avoid any sharp configurations which would tend to catch on or abrade the'clothing. The anti-friction bearings 74, 76 and 78 preferably are of synthetic plastic easily obtained.
