Abstract

Described herein is a connecting link which may be adjusted for length and which may be designed such that the portions to be accessed, to effect adjustability, may be positioned anywhere along the length of the link. There may be instances in the assembly or mechanical parts where space is at a premium and adjustment of motion-transmitting members is required but space limitations restrict the accessibility of the members. Two points of accessibility are necessary to adjust the device illustrated in the figure.

Motion Imparting Link Having an Adjustable Length

Described herein is a connecting link which may be adjusted for length and which may be designed such that the portions to be accessed, to effect adjustability, may be positioned anywhere along the length of the link. There may be instances in the assembly or mechanical parts where space is at a premium and adjustment of motion-transmitting members is required but space limitations restrict the accessibility of the members. Two points of accessibility are necessary to adjust the device illustrated in the figure.

Referring to the figure, link portion 1 is formed with a connecting offset 2 on one end. Link portion 3 is formed with a comparable offset 2 on the opposite end. These two ends may be used to attach the link between input and output members or devices. A fastening member, preferably a threaded member 4 threaded for engagement with threaded hole 5, is passed through a slot 6 in link member 1. A tab 7 is formed on the second end of link member 3 to engage slot 8 to maintain the two link members substantially on parallel axes. Formed at any point along the link where both link members 1 and 2 overlay each other are triangularly shaped holes 9 which are oppositely oriented.

To adjust the link after assembly, threaded member 4 is loosened and a screw driver or other similar instrument inserted through the aligned holes 9 and turned clockwise to extend the link and counterclockwise to shorten the link. When the...
