Connecting apparatus for power shovel tooth adapters

Claim 2

Apparatus for removably connecting two separable parts, the parts fitting together in overlapping relation and each having an opening, the openings being alignable to form continuous passage when the parts are brought together, the connecting apparatus comprising: a. an elongated block having projections extending laterally from either end, the projections being of such length as to permit insertion of the block into the continuous passage, and spaced to receive therebetween one of the two parts, the back side of the block having undulations formed therein; b. a wedge dimensioned for insertion into the passage in wedging relation between the block and the other of the two parts, one side of the wedge having a recess intermediate its ends, the recess being lined with a resilient pad of a predetermined thIckness; c. and a block-engaging member disposed in the recess and having an undulated block-engaging face for matable engagement with the undulations in said block, the block-engaging member constructed and arranged for rockable movement within the recess upon engagement with the block.

Claim 3

The apparatus as defined by claim 1, wherein the resilient pad is rubber.

Claim 4

The apparatus as defined by claim 2, wherein the rubber is bonded to the surface defining the recess and to the block-engaging member.

Claim 5

The apparatus as defined by claim 1, wherein the recess is rectangular in shape.

Claim 6

The apparatus as defined by claim 1, wherein the top and bottom edges of the block-engaging member abut the upper and lower surfaces of the recess, thus precluding relative longitudinal movement therebetween.

Claim 7

Apparatus for removably connecting two separable parts, the parts fitting together in overlapping relation and each having an opening, the respective openings being alignable to form a continuous passage when the parts are brought together, the connecting apparatus comprising: an elongated block having projections extending laterally from either end, the projections being of such length as to permit insertion of the block into the continuous passage and spaced to receive one of two parts therebetween; a wedge dimensioned for insertion into the passage in wedging relation between the block and the other of the two parts; one of said elongated block and wedge having an undulated engaging face; the other of said elongated block and wedge having a recess intermediate its ends, the recess being lined with a resilient pad of predetermined thickness; and an engaging member disposed in said recess and having an undulated engaging face for matable engagement with the undulated engaging face of said one elongated block and wedge, the engaging member constructed and arranged for rockable movement within the recess.

Claim 8

Apparatus for removably connecting two separable parts, the parts fitting together in overlapping relation and each having an opening, the respective openings being alignable to form a continuous passage when the parts are brought together, the connecting apparatus comprising: an elongated block having projections extending laterally from either end, the projections being of such length as to permit insertion of the block into the continuous passage and spaced to receive one of two parts therebetween; a wedge dimensioned for insertion into the passage in wedging relation between the block and the other of the two parts; one of said elongated block and wedge having an undulated engaging face; the other of said elongated block and wedge having a recess intermediate its ends, the recess being lined with a resilient pad of predetermined thickness; and an engaging member disposed in said recess and having an undulated engaging face for matable engagement with the undulated engaging face of said one elongated block and wedge, the engaging member constructed and arranged for rockable movement within the recess.
