Even though 51 other patents reference this original swing-arm patent, almost none of those "improvements" are in use today.

The original patent has remained unchanged .... until now!

The patent has 20 pages of diagrams and 30 pages of description. It reads clearer than any "manual" ever written for a swing-arm inserter. To look at the 60 year old design is to look at the machine that is sold as the current design by 5 other US companies.

If you would like a copy of the patent, we will be pleased to provide you one for historical and or even current reference.
