To all whom it may concern:

' Be it known that I, J ULES MI HE MARIE- 'lRt'i-n t-LT, engineer, of 51 Avenuecles Ternes. 1n the city of Paris, Republic of France. I

have" invented Improvements in l rictional Betta-(ling Means for Spring-Vehicles, of

which the following a full. ole-or, and ex- :ict speolticzitiom This; invention relates to thoclass 0t vehi springs are employed cles in general Where. to relieve ]Olt]1l'j.:-1]l(l vibration, and lmrticue l:u']\' motor cars and crcles of tlie'ivarious 'tll-lIIlOWIl kinds. lt'otivithstanding tl e fnse of springs for supportingthe bodies of such \elneles .miich inconvenience is felt from the shocks and Yibretions due to the Wheels,- and pzirticuiarl x the .t'ront steering Wheel or wheels. striking obstructions in the m; d.

The object of the aresent intention is to overcome .or nrteria ll hatween the moving parts or between the running-gear and the SPllllg-EHPPOIiBCl parts,

wl'iereliw said frictional devices serve its l.rul\'es to retard the too-rapid vibration or mcwenwnt .ot the ports.

The invention nu iy be embodied in tori; ous ways and. by details of mechanism which ary. the particular eonstliuetion depending to a cons derableexte it on" the kind 0t vehicle to which it is applied I This application is a division 0t application filed June 9, 1905, Serial No. 26 L523,
