En the drawings, 1 indicnes: e metal bar haring seem-eil n one end extensions 2 and 3, by ineens boils fl. rllhe opposite end of he extensions., 2 :incl 3, are rovifilefl with glionliiers, and e, beniJ et right' angles to he main body porion of said extensions. A drew-bar, 7, provided with extension irnis, 8 and 9, ne one end, reeiproentes be i 'een Athe exensions 2 and 5. A spiral spring.y lyhziving one end sented against the shoulders, 5 and 6, and its opposite end seiied against. he extensions 8 and 9 of the (lier-:bnr 7., proi'iiee n enshion 1for the (l nwbnr when the obj-eet drown comes in Contact with :in obstacle. fr brace, l, is secured et one end by :i bolt, 12, io the metal bar, 1. The brace, exten ls above the extensions 2 11ml 3, mul 'o which pivot a lever, 13; one enil oisixi l lever contacting with the extension, 8, on the bnr 7, and the upper end of lhe lever being connected by a cable, i4, (inhiber snimble means tolithe clutch, throttle er operative valve of a traction enzgine of motor. A spiral spring, 15, I secure et obo end to he bolt, 12, and :it its opposite cnil lio the end of the lever, 13, below the support, 11v which normallyv holds the lower encl of the lever, 13, in Contact with the arm, 8. (llevises, 16, are connected to enel) end of he flraftnpplianee, whereby he Same muy be suitably connected between rho trec'tion engine or motor and the object being drawn thereby.

irn the operation .of my device, the draft eppliemm will be Connected to the tzirtion engine or nioior :if one end by means ol' the elevis, and :it the other end o :1 gung-plow, harvesting: implement, or Object to be drawn, nml the cable, i4, connected :il: one oml fo the lever, 13, :nifl connected to the clnieh or Throttle-valve lever or n traction engine :il ite opposie enfl. The engine being,f started moves therewith the objeelwio be drawn. lilhen saiol object comes in Contact with :my obstacle in iis path, the spring, l0, will be Compressed and by the forward movement of the bei: 7, drawing with it the lower end@ of the lever, 13, ,aid movement will release the clnteh and shut off the motive power of the traction engine or motor7 and thus bring it to a stop, preventing any shook or injury which would otherwise be caused by the object being;` drawn coming; in Contact with an obStacle and not provided with means for absorbing' the shook of the Contact.

ll'hat l elaiin as' new and desire to Secure ln a device of the character described, a bar having extensions secured thereto, said extensions being' provided with shoulders extending' at right angles to said bar, a draw bar having arms extending at right angles
