Abstract

677,252. Rope railways. WEBB, CO., J. B. Aug. 5, 1949. [Aug. 14, 1948] No. 20388/49. Class 104 (ii). A conveyer system for propelling a truck 27 7 upon the surface of a floor comprises a driven chain 19 of the known articulated rivetless or Keystone type, supported by trolleys 17 which run on a circuituous track within a trough below the floor level, the truck being provided with swivelled or castered forward wheels 32 and having a retractable driving pin 26 mounted in a tubular housing 30 in a forward position, so that it can be lowered below floor level to engage driving dogs 23 carried by the trolleys 17. The trolleys are mounted on pairs of wheels 20 at the front and rear ends respectively, and the tracks upon which the wheels run are provided, by the lower sides of oppositely directed metal channels 14 which are spaced apart to allow the passage of the trolley between them. A pair of guide rollers 21 mounted on vertical axes in the trolley bear against the lower edges 22 of the track channels to provide stability during the rounding of curves in the track, and a tongue or member 18 extending downwardly from the trolley is engaged within a link 19 of the driving chain. The dogs 23 are pivoted on the front and rear ends of the trolley 17 and provided with counterweights 25 so that they swing to engage the driving pin 26 when their relative approach to the pin is in either direction of the track. The vertical pin 26 is raised or lowered by means of a pin or handle 28 extending laterally from it through a vertical slot in the housing 30, the pin 28 being retained in the upper position by seating it in a recess 31 in the upper end of the housing. Specification 608,181 is referred to.
