Definitions
- the backup plate is in the form of a thrust platform which, as the jaws of the pliers are closed to contract the band, is cammed inwardly toward the axial center of the band clamp, forcing the bulge or offset into a generally keystone shape, thereby giving increased strength to the bulge as compared with an ordinary loop.
- the backup plate or thrust platform is made adjustable, so that when fully cammed into its most inward position, the platform occupies one of two (or more) limit positions.
- FIG. 7 is a perspective view of the thrust platform and the eccentric pin
- FIGS. 10 and 11 are views, in front elevation as in FIG. 1 but with parts broken away and in section, illustrating the manner of use of the pliers of FIG. 1 in contracting a large-diameter ring, the eccentric pin being in its upper position as in FIG. 5; 7
- FIG. 18 is a top plan view, looking down along the line XIXXIX of FIG. 17, showing the pliers about to be used to contract the hose clamp;
- FIGS. 17 and 18 depict the pliers about to compress the offset 151 of clamp 150, thereby to contract the clamp 150 about the hose 152 and the pipe 182.
- the forming edges of the jaw parts 124 and 125 grab the offset porexpanding outwardly, and forces it to assume the desired keystone shape.
- the backup plate 130 also maintains the forming edges of the jaw parts 124 and 125 in alignment as they close on the offset portion 151.
- Clamp pliers for contracting band clamps having an offset portion
- said pliers comprising a pair of complementary lever arms pivotally connected at an intermediate point by a pivot pin, said lever arms having at one end handle portions and at the other end complementary jaw portions characterized by opposing clamping edges adapted to be brought toward each other in abutting relation; a backup plate movably mounted close to but spaced from the path of closing movement of said clamping edges for receiving the thrust of the offset portion; and means actuable by said lever arms for camming said backup plate towards said jaw portions as said lever arms are moved to bring said clamping edges toward each other.
