  • Patent number: 8474230
    Abstract: The present invention relates to improvements in or relating to saddles and saddle trees, especially English saddle trees, particularly for horses. In particular, we describe a method of manufacture for a tree which is simplified by the use of leather, webbing and plastic in flat sheet material. This fabrication can be simply stitched and riveted together and a Y-bar and headplate are then bolted and or riveted to the finished leather plastic fabrication. This method of making a tree is fast, efficient, cost effective, safe, reliable, provides more consistent symmetrical performance, and above all is very light, providing a weight saving of 60% compared with conventional methods. The tree fabrication requires no additional finishing or tidying, unlike other forms of manufacture. As soon as the parts are assembled they are ready to go to the next stage of making the finished seat for the saddle.

  • Patent number: 6474052
    Abstract: The present invention describes improvements in “Western” style saddles allowing existing saddles to be converted to a European saddle panel style which will facilitate a method of modelling the underside of the saddle to fit a horse's back. There is described a panel adapted for mounting to an underside of a skirt of a saddle, the panel comprising a sheet of a padded material and a sheet of a flexationally resistive material, the sheets being generally shaped to match a shape of the skirt to which the panel will be secured, and wherein the sheets are bonded together generally around their edges to define a pocket therebetween; and wherein the pocket is filled with a resilient medium. The resilient medium may be conventional flocking, but preferably comprises at least one inflatable bladder. The use of two generally coplanar inflatable bladders arranged to provide an overlap between the two bladders, is preferred.
