FlgtlI-Bl shows the invention comprising;

a semi-circular diskl pivotally connected 1 at 2 to-a support 3' which in turn is attached to a rocker 4. Attached to disk 1 at 5 is a push rod 6 which in'turn is held in place by brace rod 7 attached to the rocker 4 at 7 one end and to the rocker arm 6'at the other. ,A spring 8 is also attached to the endo'l:

semi-circular disk '1 and rocker arm 6,v A

cord 9 attached at oneend of'semi-circulardiskl passes over the faces of corresponding pulley 10 to a pulley 11 set at right angles to pulley 10 and from there'around a pulley 12, back around a pulley similar to 11 called 11 and from there overa pulley 10 to p posite end of semi-circular disk from which it started. 1 and 10 are mounted'on an oscillating arm 20. Rollers 11and 1'1 are mounted in a housing 13 and 13f respectively, which are pivotallymounted on arm 145.3

- Extending frorn'the housings'as showniin s Figure 3 is aspring armi15 Which rests-on" a pivoted rocker arm 16 as'shovvn in Figure 4:. Directly below; pulleys 11 and '11 re shown in Figure 3.; These disks aremounted on a shaft 19, on Which'in turn is mounted a,

fan 21. Attached to spring arms 15 and 15f arecords 18, and 18 attached to the base of pulleys 10am 10 respectively, afpin 22 spectively, are rubber disks 17 and '1 'ing members With passing'through rocker arm 16 ingitssmidexerted .by spring/arm 15 .or spring armzl5.

In operation, as the rockingwohair comes 7 forward, the push =rod .6,v coming. in contact with a surface, causes the disk 1 to tiltdoWn-V avardl'y andthe cord 9, to beariagainst pulley 10-.-v. hich .in turn causes. the .oscillatingarm isaattached to pulley l0 exerts a downward .dle:- 536011101130: that therocker-amm16 may- V .oscillate according to Where the pressure is" 'T-heobject of; this invention is to utilize to 1 some useful purpose the I unused ,en'ergycreated in a rocking chair.
