Abstract: A fork for a fork lift truck having a blade and shank connected by a heel, with a top hook on the shank and a bottom hook near the heel, the bottom hook being constructed so as to be locked and unlocked to the carriage of a lift truck to facilitate engagement of the fork with the carrier and reduce manual effort of the operator and obviate special positioning of the fork prior to connection as is commonly required.

Abstract: A system for storage and shipping of boats availing of a series of adjustable support units which are connected by flexible elements to each other to prevent lateral and longitudinal movement of the boat with respect to its supported location, the support units likewise providing for fastening of a boat to the units by other flexible elements.

Abstract: A fork lift vehicle lift fork having provisions to signal a user when wear of the fork on a surface or surfaces which are subject to wear, has progressed to an extent which may result in failure of the fork if subject to further continued use, such provisions including a plate element fastened adjacent a surface in such a way as to cause automatic release of the plate element when the wear has progressed to a predetermined extent, to assure visible notice of that fact, similar provisions being suitable for use in like manner to indicate wear of a separate surface subject to wear.

Abstract: There is disclosed a method of making a fork for a fork lift vehicle, which fork is formed with an integral head, created by forging the same, into a hooked shape form, the rest of the fork being of generally conventional configuration, the fork further including a mechanism to effect latching of the same in position for use made possible by the method and ultimate form of the fork head and to make positive the positioning and release of the fork for movement into various transverse positions with respect to the vehicle.
