Abstract
A tool for removing damaged sickle teeth from a supporting sickle bar. A support member supports the sickle bar on edge with the damaged teeth being disposed within an open area of the tool. An impact member is vertically slidably mounted and transfers hammer blows to the tooth upper edge to cause shearing off of the rivets mounting the tooth to the sickle bar. The impact member, in its lowermost position, serves as an anvil during the riveting of a replacement tooth onto the sickle bar.
Claims4
A tool for shearing rivets passing through and joining sickle teeth to a sickle bar, said tool comprising,
- a base including lengthwise extending upright support members having an opening therebetween, one of said support members having an upper planar surface on which a sickle bar may be temporarily positioned on edge with a sickle tooth disposed in said opening,
- guide means on said base, and
- an impact member mounted for vertical sliding movement on said guide means, said impact member being of clevis shape to straddle said support members and having an impact surface for contact with the edge of the sickle tooth whereby blows delivered to said impact member are imparted to and cause said tooth to impart a shearing force to rivets joining the sickle bar and tooth.
