STAND No. 123.
MBE Allehin is an orthodoF overtype • wagon, embodying the charaoteristic features of its type. Its three-speed gear is of interest because of the ingenious method of operating it, with pullout pine to prevent maladroit usage. The latest-type Allchins are shown on the stand, embodying, amongst other new features. Ackerman steering and brakes on drums in the remwheels.
The gear embodies a nut and screw, of which the latter is formed on the lowerend of the steering column, the nut being. supported in guides in a bracket in the frame. This same bracket. is extended in a downward and forward direction, and it supports at its extremity the fulcrum of a beIl
crank lever, one arm of which is coupled tothe nut, while the other is enlarged and hollowed out to accommo date a Hooker-type universal joint. A rod from this joint couples to the offside steering arm.
The spring-controlled towing hook on these wagons is worthy of note, being most ingenions. A semicircular loose lining to the frame of the hook conveys the oncoming tow-bar of the trailer, and is kept pressed against the shackle pin, preventing it from falling, by a spring. When the towing-bar enters it pushes this lining forward, releasing the pin, which falls automatically into place and effects a coupling.
The other complete vehicle on this stand is a tipping wagon with high hinged sides. .
