Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
217 words
An automobile conveyor including: a. a platform providing rolling support for a tire of an automobile for passage thereof through a work area, the platform having a slot bridged by the tire; b. an endless driven chain having an upper arm run spaced below the platform in alignment to the slot; c. a plurality of rollers mounted centrally of the chain at intervals along its length, the rollers being extendible through the slot; d. a pair of followers connected to the chain at each roller, the followers extending outwards of opposite sides of the chain, the chain, rollers and followers normally following a path in which the rollers pass in a normal hidden position beneath the platform; e. means movable into and out of the path of the followers for selectively lifting a pair of followers and a roller to an elevated position in which position the roller projects through the slot above the platform so as to engage an automobile tire; and f. a pair of upper tracks, having head and tail end arranged below the platform on opposite sides of the chain for receiving any pair of followers lifted by the chain for passing a roller, in an elevated position the length of the slot so as to move the automobile through the work area.

An automobile conveyor including: a. a platform providing rolling support for a tire of an automobile for passage thereof through a work area, the platform having a slot bridged by the tire; b. an endless driven chain having an upper arm run spaced below the platform in alignment to the slot; c. a plurality of rollers mounted centrally of the chain at intervals along its length, the rollers being extendible through the slot; d. a pair of followers connected to the chain at each roller, the followers extending outwards of opposite sides of the chain, the chain, rollers and followers normally following a path in which the rollers pass in a normal hidden position beneath the platform; e. means movable into and out of the path of the followers for selectively lifting a pair of followers and a roller to an elevated position in which position the roller projects through the slot above the platform so as to engage an automobile tire; and f. a pair of upper tracks, having head and tail end arranged below the platform on opposite sides of the chain for receiving any pair of followers lifted by the chain for passing a roller, in an elevated position the length of the slot so as to move the automobile through the work area.
Claim 3
Dependent Claim
19 words
A conveyor as claimed in claim 1 wherein the followers are rolls, the rolls being coaxial of the rollers.
Claim 4
Dependent Claim
53 words
A conveyor as claimed in claim 2 wherein the chain is formed having links, each link having spaced apart side bars and an interconnecting pintle, each roller being mounted for rotation on a pintle between the side bars and the rolls being mounted on opposite ends of the pintle exteriorally of the chain.
Claim 5
Dependent Claim
80 words
A conveyor as claimed in claim 1 in which the means e. includes: g. a pair of ramps swingably mounted at the head end of the tracks for movement between inclined positions into the path of the rolls and substantially horizontal positions out of the path of the followers; h. overacting resilient means for yieldably resisting movement of the ramps out of either position; and i. means for moving ramps to either position against the action of the resilient means.
Claim 6
Dependent Claim
26 words
A conveyor as claimed in claim 1 wherein the tracks are disposed so that only an upper segment of a lifted roll projects above the platform.
Claim 7
Dependent Claim
49 words
A conveyor as claimed in claim 4 wherein the ramps are mounted intermediately of fore-and-aft ends for swinging movement about transverse axes so as for swing automatically to swing from inclined positions to horizontal positions under the weight of the followers as the latter pass over the transverse axes.
Claim 8
Dependent Claim
28 words
A conveyor as claimed in claim 1 including a pair of lower tracks spaced below the upper tracks upon which the followers ride when following the normal path.
Claim 9
Dependent Claim
57 words
A conveyor as claimed in claim 7 including ramps swingably mounted at the tail ends of the upper tracks for free swinging movement between inclined and substantially horizontal positions for guiding any pair of lifted followers from the upper tracks to the lower tracks and swinging upwards to permit passage of any followers following the lower tracks.
