Travel stop

A spring support device adapted to support installed piping and similar loads which are movable over a range of travel during changes in operating conditions thereof, comprising a casing having upper and lower end plates and at least two longitudinally orientated side slots, terminating at said upper plate, a compressible spring positioned within said casing between said end plates and bearing at its lower end against said lower plate, a spring plate having outwardly projecting ears laterally extending into said side slots and disposed upon the top of said spring and normally movable therewith towards and away from said upper plate, and load carrying means engaging said spring plate and extending through an opening in one of said end plates for connection with the load to be supported, spacer means disposed proximal said side slots between said top plate and said spring plate for maintaining said spring under a minimum predetermined compression, means for retaining said spacers in position and for simultaneously limiting a predetermined maximum compression of said spring, both said spacer and spacer retaining means, being laterally shiftable through said side slots for entrance and removal from said casing, said upper plate having an inwardly projecting slotted opening positioned at the top of each said side slot, said spacer retention means comprising a headed bolt received in each such opening, said bolt having a lower end adjustably engagable with threaded openings in said spring plate ears, said spacer means comprises hollow cylinders longitudinally orientated between said upper plate and said spring plate and wherein said bolts pass through said cylinders, the height of said cylinders determining said predetermined minimum compression.
