发明名称 Tool for installing scarifier teeth
摘要 A tool for installing scarifier teeth in a hole in a socket attached to a drum, as by using an identical pin and air hammer as can be used for removing the teeth through an aperture at the rear of the socket. The tool has a circular hole with an inner bevel at an angle of not less than 321/2 DEG but preferably 35 DEG to the center line of the hole, while this bevel engages an outer bevel of a body of the tooth adjacent a shoulder to which weld metal attaches a tip of relatively hard metal to the body, or a flare or skirt of the body adjacent a stem of the tooth. The aforesaid holes in the body may be of different length and different diameter, depending on the distance from the point of the tip to the bevel or the flare or skirt. The opposite end of the tool is provided with a hole to receive a pin which may be impacted by an air hammer, while a shim may wedge the pin in this hole to prevent the tool from flying off the pin if the air hammer is accidentally triggered.
