Each impact member is provided with an interlocking joint structure for selectively interlocking with the joint portion of the hammer. Preferably, the joint structure is a flared tenon, and the joint portion is a flared mortise dimensioned to mate with the tenon and form a dovetail joint. Recesses are formed in the tenon for receiving portions of a bolt and nut assembly which retains the tenon in the mortise. By arranging the mortises to extend in a direction of movement of the hammer, the impact member will be biased toward a seated position during an impact thereon so that the bolt and nut will be relieved of strain.，下面是Removable caps for crusher hammer assembly专利的具体信息内容。
1. A hammer assembly for a crusher, comprising, in combination: a. a hammer member arranged for being mounted on a rotor of a crusher, and provided with a first substantially planar surface arranged facing outwardly transverse to a radial plane of the associated rotor, a second substantially planar surface extending obliquely from the first surface toward the associated rotor and in a direction of rotation of the rotor, and a projecting portion forming a wall arranged extending transverse to the direction of rotation of the associated rotor and radially outwardly from the first surface along an edge thereof spaced from the second surface; b. an interlocking joint portion provided on the first surface and arranged extending perpendicularly from the wall to the second surface; c. an impact member having a pair of joined legs arranged forming a substantially L-shaped body portion; and d. an interlocking joint means provided on the body portion for removably interlocking with the joint portion, an outside surface of one leg of the body member arranged forming an impact surface for the hammer assembly.
2. A structure as defined in claim 1, wherein one of the interlocking joint means and the interlocking joint portion is a flared tenon and the other is a flared mortise dimensioned to mate with the flared tenon and form a dovetail joint.
3. A structure as defined in claim 2, wherein the interlocking joint means is the flared tenon, and the interlocking joint portion is the flared mortise.
4. A structure as defined in claim 3, wherein the wall is arranged enclosing an end of the flared mortise and provided with an opening, and further including means arranged in the opening for retaining the tenon in the mortise.
5. A structure as defined in claim 4, wherein the flared tenon has walls which diverge outwardly from the body portion and join with an outer surface provided with a recess for receiving the retaining means.
6. A structure as defined in claim 5, wherein the retaining means is a headed bolt and nut, and a further recess is provided in said outer surface and arranged at the junction of the impact member legs in communication with the recess for receiving one of the bolt head and the nut.
7. A structure as defined in claim 6, wherein the hammer member is provided with a plurality of flared mortises, and a plurality of impact members are arranged in the mortises for forming a continuous impact surface on the hammer member.
8. A structure as defined in claim 7, wherein the hammer member is a bar-type hammer having a longitudinal extent and arranged for mounting on the rotor of the impact rock crusher, and the projecting portion extends longitudinally of the hammer member, with the mortises arranged extending perpendicularly from the projecting portion in a direction of movement of the hammer member for cooperating with the tenons and seating the impact members during an impact thereon and relieving strain from the associated retaining means.
9. A structure as defined in claim 8, further including a pair of wedges connected together by a rod having screw-threaded end portions and nuts threadingly engaging the end portions, and wherein the hammer member is provided with a projection arranged for cooperating with the wedges and with at least one aperture for receiving a bolt, the wedges and bolt selectively retaining the hammer member in a recess provided in the crusher rotor.
10. A structure as defined in claim 1, wherein the hammer member is a bar-type hammer having a longitudinal extent and arranged for being mounted on the rotor of a crusher and is provided with a plurality of interlocking joint portions, and wherein a plurality of impact members is provided, each having interlocking joint means arranged in the interlocking joint portions for forming a continuous impact surface on the hammer surface.
11. A removable impact member for a crusher hammer, comprising a body member having a pair of legs arranged substantially L-shaped, one of the legs forming an impact surface and interlocking joint means provided on the other of the legs for selectively interlocking with a mating interlocking joint portion provided on an associated crusher hammer member, the interlocking joint means being a flared tenon having walls which diverge outwardly from a body portion of the body member and joint with an outer surface provided with a recess arranged extending parallel to the diverging walls and a further recess arranged at the juncture of the body member legs for communicating with said recess, said recess and further recess arranged for respectively receiving a bolt shank and one of a bolt head and a nut.
12. A structure as defined in claim 9, further including the rotor, wherein said rotor is provided with means for mounting the hammer member.
