Abstract
An ice breaking attachment for impact hammers. The main component is a rigid metal beam used to transfer the blows of the impact hammer to the ice surface and then when the beam breaks through the ice distribute the impact of those blows over a large enough area to prevent damaging the underlying surface. The beam has a convex lower edge that also helps prevent damage to the underlying pavement. A vertical metal sleeve welded at the center of the beam accepts the blunt end of the impact hammer bit, and tether cables or chains attach the apparatus to the frame of the impact hammer.
Claims2
A method of removing accumulated ice from paved surfaces without damaging the underlying paved surface consisting essentially of the steps of:
- (a) Impacting a metal beam at its center;
- (b) Using the beam to transfer the blows to accumulated ice to fracture and break the ice;
- (c) Using the beam to distribute the blows over a large enough area on the pavement to prevent damage to the pavement;
- (d) Providing a convex bottom edge on the beam to prevent chipping the pavement;
- (e) Providing a means of attaching the beam to an impacting device.
An ice breaker apparatus to be used in conjunction with an impact hammer for removing accumulated ice from paved surfaces, without damaging the underlying paved surface consisting essentially of:
- (a) A rigid metal beam of a length that will transfer blows from an impact hammer to fracture and break up ice but will distribute those blows sufficiently to prevent damage to the more rugged underlying paved surface;
- (b) A convex striking surface on the bottom of the beam to help prevent chipping the pavement;
- (c) Tether cables and a vertical sleeve centered on the beam to provide a means of attaching the beam to an impact hammer.
