ROCKING-CHAIR.

Application filed April 8, 1925." Serial No. 21,083;

poses. Another object ,of my invention is the provision ofan attachment for rocking chairs having a compressible back portion wherein the, movement of the persons body during the :rockingoperation will actuate the compressibleback portion and this action will be utilized for compressing air adapted to be usedzinnwarm weatherasa cooling medium. :1 l p n.

A further object of my invention is the provision of. a device. set forth above wherein there is included :astorage, chamber. in whichrthe compressed air is. stored v wherein manually operated means isemployed for utilizing the, air, stored within the 4 chamber as ,a' cooling; medium. r -7. With the above and my inventioni consists in the novel features of construction and the combinationof parts to ;be hereinafter more 'fullyhdesoribed,

Fig. 7 isa detailed section on-the lines 7 7 ofFig. 6. Referring more ings, itwill-be noted that my improved attachment is preferably incorporated in that type of rocking chair having ajcompressible back portion, the chair in the present in stance including the usual rockers 1,'with the front legs2 and the rear-legs 3, extendparticularly to the draw- 5 ing upwardly therefrom to supp'ort'the seat 4 and side arms 5. 'lher-backisformed of a flexible covering 6 suppo1 -ted uponthe outer ends of the coiledsprings 7 and inner ends of which are connected to the back portion 8. From this it will be noted that when the person is rocking in the chair the forward movement of theirocker willghave a tendency to cause the backjof the person to'move forwardly allowing the springs .7 to expand' upon the flexible covering and will com-- press the springs 7 uponthe backward hove-I ment, an action which 1s bound to talze'place in rocking chairs having a compressible or flexible back. l i 7 In the back portion 8 of the chair atonewayvalve 9 is mounted which opens into'the chamber 10 between the fiexible meaiissfi and the back of the chair "and within this chamber-lsthe transverse partition .11 forming the chamber 12 at thetop kind disposed between the chambers 10 and 12 within the c .pariia nsl ne aw 'yj e 1e p -i through V mitting the air to pass into the chamber 12 t, p yentmaeny eekw m vemen Je the a r into the chamberlO, and both valves 9 ;and being springgcontrolled as illusif trated. so; that it will normally retain them n a v et ivp eiti uF e h .e et
