LOAD SUPPORT HAS LINEAR VERTICAL MOVEMENT AND ADDITIONALMOVEMENT FOR ALIGNING AND MOUNTING LOAD AT A SPECIFICLOCATION:
(under the class definition) Apparatus having means constructed to move an article linearly in a vertical direction and means for moving said article additionally in other directions or into different attitudes for the purpose of establishing a specific positional relationship between the article and a means to which it is to be attached.
(1) Note. A mere platform (e.g.,., forks of a fork lift truck) or bed means upon which any article may be placed are not included under the definition. See, for example, subclasses 427+ for shovel or fork type vertically swinging load supports.
(2) Note. Article position changing manipulators include any movement transmission means which, when activated by manual or other means, causes the article to move and change position. A swivel mounted article support, per se, permitting the position of the article to be changed as a result of manual engagement with the article, is, for example, in subclasses 754+ below.
