Description

l rails, '1 oe :tonnel up since is adequate, .ably rigid and reeonstruetioo is so nelly small enel liability Aunusual t oit order in l; alperieiioecl amateur. soribeel illustrated our in- 'p ad. sliding front of an 'png camera hut we wish it rm- .ie invention is applicable to other similar structures, the
' meets which are those above eet s to ee who 'that mooinfiuhe details of eeni r elo not limit eserl'oeol anal.
in appmfetus oit class stated, the combination of e slidingy part, e slideway spring actuate looking levers t one enfl to the Sliding part, a art upon each lever the heveleel enel thus sliclepon the levers aetuating spring therefor may he compressed and the' looking levers withdrawn from engagement with the sliding part and slicleway.
2. ln apparatus or.' the Class stated, the combination of a sliding part, a slideway therefor, looking levers pivoted at one end to the sliding part, a spring interposed hetween the levers which normally tends to move them outwardly, a laterally projecting part upon each lever adapted to engage the slideway and to look the sliding part thereto, and means upon the levers whereby they may he moved inwardly against the stress of the spring, parts removed from Contact with the slidewey.
3. ln apparatus of 'the class stated, the combination of e, sliding part, a slideway therefor, locking levers pivoteol at one end 'to the sliding part, a spring interposed between the levers which normally tends to move them outwardly, a laterally projecting part upon each lever adapted to engage the slideway and to look the sliding part thereto, means upon the levers whereby they may be moved inwardly against the stress of the spring, and their said looking parts removed from Contact with the slideway, enel a oonfiner plate which overlaps the free endeof 'the .spring and the levers, thus assuring their proper relation to each other.
In testimony whereof we have signecl our names to this specification.
