In the improved sway bar of a doubletree, whi:fll etree, or neck yoke. represented in our engraving, the strength of the wooden portion is materially increased by a brace rod, so that the bar may be made much lighter while still furnishing the necessary strength. Each end of the sway bar is fitted with a cap or thimble, whereby it is protected from abrasion and splitting, and to which the clevises are attached in the ordinary way-set up at the ends of these caps.

By using the rod in connection with the wood, as described, the dra ft on the rod and pressure on the wood are both endwise, theIeby, it is claimed, com bining the utmost strength of both materials. These doubietrees, whi:fll etrees, and neck yokes l.ave, we l�arn, been thoroughly tefted with success. With not very expensive mao cbinery, it is stated, they can be manufactured
