| Wilhelm, Parker & Hard - patent attorneys
This invention relates to feed mechanisms for the tool carriages of lathes and the like. The ordinary screw-cutting lathe is provided with a power-driven feed shaft or lead screw, and the carriage is moved longitudinally along the bed for feeding the tool length wise of the work, either by the direct connection of a feed device or screw nut on the carriage with the feed shaft or screw, or by gearing connecting the carriage with a toothed rack on the lathe bed and operated by hand or by power, and the cross slide is also operated to feed the tool crosswise of the work by gearing operated by hand or by power, depending upon the movement of the tool required for the work being performed. When either the cross or longitudinal power-driven gear feed is used the screw feed must be thrown out of action, and vice versa when the screw feed is used the cross and longitudinal power-driven gear feeds must be thrown out of action to prevent injury to the lathe of work. One of the primary objects of this invention is to provide lathes with reliable means of simple construction whereby neither the longitudinal nor cross gear feed can be power operated when the other or screw feed is in operation, but which enables either gear feed to be employed when said other or screw feed has been thrown out of action. Another object of the invention is to construct the feed mechanism so that the hand crank or device for feeding the carriage longitudinally will not be rotated while the carriage is being operated by the screw feed.
