Abstract
Abstract This invention relates to a quick release clamp for applying the laterally constrictable ears of a cable connector to the terminal of an electric storage battery. The clamp includes a bolt having a threaded shank terminating at one end in an enlarged head. The shank is dimensioned to extend through aligned holes in the connector ears, with the bolt head being located on the outermost side of one of the ears. A nut is threaded onto the bolt shank on the outermost side of the other of the connector ears. A cam lever is rotatably connected to the bolt, and is adjustable between a closed position cooperating with the bolt and nut to laterally urge the connector ears together to grip the battery terminal therebetween, and an open position permitting the connector ears to move away from each other to an extent sufficient to permit the cable connector to be removed from the terminal.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
171 words
A quick release clamp for applying the laterally constrictable ears of a cable connector to the terminal of an electric storage battery, comprising: a bolt having a threaded shank terminating at one end in an enlarged head and having a slit extending axially through said head into said shank, said shank being dimensioned to extend through aligned holes in said ears with said enlarged head being located on the outermost side of one of said ears; a nut threaded onto said shank on the outermost side of the other of said ears; and a cam lever received in said slit, said lever being rotatably connected to said bolt by means of a pin extending transversally across said slit, said lever being adjustable between a closed position cooperating with said bolt and nut to laterally urge said ears together to grip said terminal therebetween, and an open position permitting said ears to move away from each other to an extent sufficient to permit said cable connector to be removed from said terminal.
Claim 2
Dependent Claim
171 words
A quick release clamp for applying the laterally constrictable ears of a cable connector to the terminal of an electric storage battery, comprising: a bolt having a threaded shank terminating at one end in an enlarged head and having a slit extending axially through said head into said shank, said shank being dimensioned to extend through aligned holes in said ears with said enlarged head being located on the outermost side of one of said ears; a nut threaded onto said shank on the outermost side of the other of said ears; and a cam lever received in said slit, said lever being rotatably connected to said bolt by means of a pin extending transversally across said slit, said lever being adjustable between a closed position cooperating with said bolt and nut to laterally urge said ears together to grip said terminal therebetween, and an open position permitting said ears to move away from each other to an extent sufficient to permit said cable connector to be removed from said terminal.
Claim 3
Dependent Claim
27 words
The quick release clamp of claim 1 wherein said lever is rotatably adjustable about an axis extending transversally with respect to the longitudinal axis of said bolt.
Claim 4
Dependent Claim
43 words
The quick release clamp of claim 1 further comprising a pressure washer axially received on said shank at a location between said head and the outermost side of the said one of said ears, said cam lever being engageable with said pressure washer.
Claim 5
Dependent Claim
21 words
The quick release clamp of claim 3 wherein said bolt, nut, pressure washer and cam lever are fabricated of stainless steel.
Claim 6
Dependent Claim
22 words
The quick release of claim 3 wherein at least one side of said pressure washer is countersunk to receive said cam lever.
Claim 7
Dependent Claim
206 words
A quick release clamp for applying the laterally constrictable ears of a cable connector to the terminal of an electric storage battery, comprising: a bolt having a threaded shank terminating at one end in an enlarged head, said bolt having a slit extending axially through said head into said shank, said shank being dimensioned to extend through aligned holes in said ears with said head being located on the outermost side of one of said ears; a cam lever received in said slit and rotatably connected to said bolt by means of a pin extending across said slit in a direction transverse to the longitudinal bolt axis; a pressure washer axially received on said shank at a location between said head and the outermost side of the said one of said ears; and a nut threaded onto said shank on the outermost side of the other of said ears, said cam lever being rotatably adjustable between a closed position cooperating with said bolt, nut and pressure washer to laterally urge said ears together to grip said terminal therebetween, and an open position permitting said ears to move away from each other to an extent sufficient to permit said cable connector to be removed from said terminal.
