Abstract: A temporary barrier post having a main pole, adjustable post, and bracing shaft. A joint assembly is supported on and can slide axially along the main pole. An end of the adjustable post is connected to the joint assembly such that the adjustable post can rotate relative to the joint assembly. A coupler is fixed to the adjustable post axially between the proximate and remote ends such that the bracing shaft is pivotally connected to the adjustable post. The temporary barrier post is adjustable between an expanded condition, in which the adjustable post extends laterally relative to the main pole, the bracing shaft is oblique relative to the adjustable post, and the adjustable post and the bracing shaft retain the main pole in a set location via the joint assembly, and a collapsed condition, in which the main pole, the adjustable post, and the bracing shaft are parallel.

Abstract: The present invention provides a copyholder having a ratchet mechanism including a flexible rack attached to a line guide with the rack being operable by a pawl which is moved by a foot operated actuator functioning through a cable to move the line guide in discrete steps the magnitude of which are adjustable. Manual adjustment of the line guide is permitted when the ratchet mechanism is in an inoperative position.

Abstract: A semi-automatic attach-detach snowplow mounting comprising two mounting mechanisms each comprising a pivotally mounted U-shaped latch member which cooperates with a slot to captively hold a mounting pin, the latch member being locked in place by a locking lever when in a first position and permitted to pivot to release the mounting pin in a second position of the locking lever. The locking lever being spring biased to both of its positions.
