Abstract
Abstract A clamping tool for disposing a resilient clip over clamping structures adapted to be secured together. The tool comprises a seating member adapted to receive the head of the clip, a C-shaped arm connecting the seating member to a handle assembly and a toggle assembly. The toggle assembly has a movable shaft extending into a bore provided in the handle assembly and in the direction of the seating member. A lever arm is pivotally connected to the shaft to direct the shaft against one side or edge of the clamping structures such that a clip received in the seating member and disposed over the clamping structures located between the shaft and the seating member, will, upon application of adequate manual force, extend over and secure the clamping structures together.

Claim 1
Independent Claim
152 words
A clamping tool for disposing a resilient clip having two leg portions each with inwardly directed extensions thereon over a clamping structure adapted to be secured together by forcing said extensions of said clip over mating ledges on said structure comprising: a seating member having a recess therein adapted to engage the head of the clip to be applied to the clamping structure, a generally C-shaped arm connected at the one end thereof to said seating member, a handle assembly located adjacent the other end of said C-shaped arm having a bore therethrough in the direction of the seating member, and a toggle assembly fitted into said bore and having a movable shaft connected thereto, said shaft having a tip adapted to be displaced along a line substantially centrally directed toward said recess in the seating member to engage the clamping structure and force said structure past said extensions of said clip.
