Automobile conveyor apparatus having a continuous chain running beneath a slotted car supporting platform, the chain having pushing assemblies mounted at spaced intervals thereon normally passing beneath the platform and selectively movable on passage of a front wheel and rear wheel of the automobile over an advance end of the platform to a tire engaging position supported on top of the platform. A ramp, spring urged to, and releasibly locked in, a horizontal supporting position at an opening in...

The invention is a conveyor or transfer means for wheeled vehicles. A helical member or worm is provided in a trough or channel extending in the direction that the vehicle is to be transferred or moved. One or more wheels of the vehicle directly engage a convolution of the helix or worm which is power driven to rotate about its axis so that the convolution of the helix exerts a driving thrust directly against the vehicle wheel to move or convey the vehicle.

A duplex chain conveyor system for conveying articles along a conveyance path is provided. The duplex chain conveyor system includes a trolley device which is detachably engageable with a driven engagement member attached to a driving chain which moves within a power rail. When the trolley device is coupled with the driven engagement member, the trolley device is pulled forward on the free rail disposed along a predetermined conveyance path. An article carrier, such as a truck or hanger, is conn...

A conveyor for transporting a vehicle along a track through a carwash is adapted to selectively lift a roller mechanism through a first opening at the forward end of the tire track for engaging the front tire of a vehicle to convey the vehicle along the track until the rear tire moves beyond the first opening whereupon the roller mechanism engaging the front tire drops through another opening at an intermediate location along the track and a second roller mechanism is lifted through the first op...

An automobile conveyor which has a plurality of automobile pushing units having pushing rollers spaced at intervals along an endless chain which travels over sprockets mounted for rotation about vertical axes. The rollers are swingable in a plane transversely to the chain. Means is provided for selectively swinging any of the rollers on an advance run of the chain into a pushing position behind a tire of a wheel of an automobile so as to move the automobile and means is provided for enabling a r...

The specification discloses a pusher device for use with the conveyor chain of a car washing installation, or the like, in which the pusher device includes a bracket adapted for manual engagement with and disengagement from the chain and having support rollers rolling on the vehicle wheel support surface and pusher rollers rollingly engageable with a wheel of a vehicle passing through the installation.

A device for moving a wheeled vehicle along a predetermined path having a track alongside the path with pusher means operating slidably along the track and arranged to push against the wheel of a vehicle in the path to move the vehicle along the path and mechanism to move the pusher means slidably along the track.

A conveyor for a vehicle washing system. The conveyor includes an endless chain located above grade level so that both the conveying path of the chain and the return path move in a common horizontal plane. A series of roller units are attached at spaced intervals to the chain and are adapted to engage the tire of a vehicle to convey the vehicle through the washing unit. A provision is made at the entrance end of the conveyor for enabling the roller units to selectively by-pass the vehicle tire. ...

Apparatus for moving a vehicle along a path of travel such as through a washing installation includes an endless horizontally disposed drive chain having a return path outside of the path of travel of the vehicle, a plurality of on-demand roller assemblies for selectively engaging a wheel of the vehicle, a drive motor for the chain, a self-lubrication assembly, staggered load-bearing surfaces for supporting the roller assemblies regardless of the degree of wear adjustment to the apparatus, and a...

The conveyor system features plural endless and independently powered conveyor chains traveling individual guide tracks, one chain and track representing a main power conveyor line traversing the entire length of the system, and one or more further and similar chain and track-type branch lines which, at spaced zones therealong, converge and diverge in relation to the main line, paralleling the latter through some length. Thus, pusher dogs on the parallel-traveling conveyor reaches may selectivel...
