The improved joinery system provides a concealed means for connecting two or more wooden members at a variety of angles. Each connection consists of a short tenon on one member being inserted into a shallow mortise in the second member and having a bolt passing through one member into the second member where it threads into an anchor nut. The anchor nut is a metal rod with one or more threaded holes for bolt insertion. The anchor nut is held in place within the member in correct alignment by means of a pressed in sleeve through which the bolt passes when inserted to complete the connection. Wooden plugs may be used to fill anchor nut and bolt counterbores to fully conceal fastening hardware. A Belleville disc springs may be used btween bolt head and flat washer to maintain joint tightness during wood shrinkage.

Timber joining system

This invention discloses a rubber composition that has a high capacity for absorbing energy. This rubber composition has a Shore A hardness in the range of about 20 to about 30 and is nontoxic. Thus, it has excellent properties for use in articles that come in close proximity to humans or animals which benefit from the ability to absorb energy, such as shoe soles, gun butt pads, baseball glove insert pads, helmet liners, hammer handles, horse shoe pads, tumbling mats, and the like. The energy absorbing rubber composition of this invention comprises a mixture of a polynorbornene rubber, a plasticizer, and a resin which is incompatible with the polynorbornene.
