'iueipsl object of my invention is t0 generally in'i nore the construction shown in the patent zhove referred to and to use n tin; or 1- spring for forcing the locking block into engagement with the sleeve on the end of the hr; he henna, which ronstruetien does away with the use of u coil spring, and thereby eeononiizes space, which is an impl'rtaint, factor in hrulte heuni construetion. in the patent above referred to the heads are :njljustnhly locked on the ends of the l'ietini in such a manner that when the beams are hung" in proper position the heads will uuloimiticully adjust themselves to the surfer-es o l. the wheels regardless of the (chm-tun i. or pesition of the brake l'nrngiugs tun! (luringwhich automatic adjustment the locking blocks between the heads and beam yield tn pen-nit the heads to assume their proper positions, and. which hloeltslirxnly to ln'u lce Specification of Letters Patent.
