Abstract

The positioning clamp can be manually moved to any position along guide rails, at which position clamping is achieved automatically. The clamp carries an item to be positioned such as the side of a card hopper which is to be modified to receive cards of different sizes. This is achieved by oppositely oriented springs 1 and 3 which each bite into guide rails 9 until pushed free by handle member 5.

Universal Adjustable Clamp

The positioning clamp can be manually moved to any position along guide rails, at which position clamping is achieved automatically. The clamp carries an item to be positioned such as the side of a card hopper which is to be modified to receive cards of different sizes. This is achieved by oppositely oriented springs 1 and 3 which each bite into guide rails 9 until pushed free by handle member 5.

Guide rails 9 are fixed to create an open slot along which the clamp assembly can be positioned. The assembly has internal body 7 which provides structural support for springs 1 and 3. Body 7 also is internal to and loosely supports handle member 5. Body 7 carries limit stops 11 and 13 on each side near springs 1 and 3.

With handle 5 in its normal position, each spring 1 and 3 takes up a normal position in contact with rails 9. External forces tending to move the clamp in either direction pull one of springs 1 or 3 into tight contact with rails 9. Such tight contact prevents movement of the clamp.

On the other hand, a manual force on handle 5, exerted through the finger hole, first results in the projections 15 freeing either spring 1 or 3. For example, upon movement of member 5 to the right, projections 15A and 15B bend spring 3 away from rails 9. Subsequently, handle 5 abuts limit stop 13. Further movement of handle 5 causes the entire clamp assembly to move along rails 9, spring 1 sliding along rails 9. Movement can be effected in either dir...
