u I'claim: l f 1.` Incombination an overhead track, a

lcarriage mounted `on said track to traverse the sanie,I spaced apart bars connected at their upper ends to the carriage' and extending downwardly therefrom, brackets secured to thelower ends of said bars having horizontal extensions, a platformV pivotally mounted at the free ends of said extensionsand normally overbalancing to occupy a vertical position, and releasable latching means for holding theplatformuin a horizontal position.

2. A carrier comprising, a carriage, suspending means ccnnected to and extending downwardly from the carriage, brackets secure'drto theflower. end of the suspending vmeans having laterally extending horizontal arms, a'platform pivotally mounted to turn about a horizontal axis at the free end of said 'arms and normally occupying a. vertical position when free to do so, latching means engaging with said platform to hold the same in horizontal position, and means for releasing the latching means. f

3. A carrier-comprising, a carriage adapted to traverse-a track, lspaced apart bars connected at their upper ends to said carriage Yand extending downwardly therefrom, means connecting' said bars at their lower portions to hold the same against movement with respectto each other, brackets secured one to each lower end of said bar, eachl having a laterally extending horizontal arm, a platform pivotally mounted on said arms to turn about ahorizontal axis and normally tilting to vertical position when free to do so, latching means mounted on said bars and engageable with said platform to hold thesame-in horizontal position, and means for releasing the latching means.

4. A construction containingtheelements iny combination defined in claim 3, each of said brackets adjacent its lower ends carrying'a roller mounted t-o turn about a vertical ,axis'at the sidethereof opposite said laterally extending arm, and means for pivotally connecting each of said bars at its upper end to said carriage whereby the bars may swing about a. horizontal axis.

5. A carrier comprising, a,carriage,vb ars v secured' at their upper ends to and '.depending from said carriage in `spaced'relation'-v to each other, brackets attached,rone to the lower end of each of said bars, each of said I v brackets having a horizontal arm at its lower end, a member vpiv'otally connected at -one end to the outer end of each arm, a platform permanently secured'to -and extendng'over ,Y n

lo and between said members', saidplatform ynormally tilting to avertical position when free to do so but'adapted to be turned to a horizontal position, a horizontal rod'mount- Y ed fory rockingy movement 'on land between 15 saidvbars adjacent theV upper ends ofthe brackets, and arms'fastened tos'ai'dvrod efX-i` .tending downwardly therefrom to engage i with said members when the platform is in A horizontal position yand hold the same against tilting to Vertical position.` A .i p

6.- A constructioncontaining the elements" in combinationfdefined in claim 5, each 'of A said. members adjacent its free end having an kl upwardly extending-lug, a roller mounted at the lower end of each arm toV engage against v said lugs and the upper sides of the free ends. offsaid members, and an operating vhandle secured to one end of said rod for rocking the l rod to disengage said rollers from said members, forthe purposes described. Y f .7. In combination, an overhead`track,a y suspending structure traversably supported on said track, and a horizontal platformk mounted at the lower end of'said suspending structure and entirely at one side thereof, the. center of said platform beinglocated sub-A'. 1 stanltially in vertical. alignment with Asaidk trac 1 '87. In combination, an ovehead track, asus- 40 pending structure traversablyy mounted yon said track, a. horizontal platform pivotally!` v supported at the 'lower end offsaid suspend ing structure and extending wholly from one` side thereof, the center of said platform being located substantially in vertical alignment Y' with saidtraok and means for releasably re'-, 1f taining said platform in horizontal position..V In testimony whereof I affix my signature.
