Manufactured by Bullard Machine Tool Co. - Bridgeport, Fairfield County CT

Pond and Wilson—patent attorneys Abstract: This invention relates in general to the art of metal working tools, and has more particular reference to automatically controlled multiple spindle turret lathes of the station type. Within this type my invention has special reference to lathes characterized by the provision of a plurality of work- carrying spindles or chucks mounted on a work carrier adapted to be rotated in step by step movements to various stations, such as loading and working stations, and a tool carrier adapted to be brought into and out of operation with respect to the work at each station, the arrangement being such that as the work is moved from station to station each tool or set of tools in a tool holder successively perform a plurality of operations thereon. It is desirable to operate the work and tool carrying devices in predetermined timed relation and sequence by automatic control mechanism so that accuracy' and precision in operation is obtained as well as uniformity and expedition. Claim: In a multiple spindle lathe, the combination with a work carrier and a tool carrier one of which is rotatable with respect, to the other, of mechanism for indexing the rotatable carrier including at pair of elliptical gears.

Manufactured by Bullard Machine Tool Co. - Bridgeport, Fairfield County CT

This patent was listed on a Bullard Maxi-Mill patent plate. Abstract: This invention pertains, to automatic 1n metal working machines, and has more particular reference to the general type disclosed in my Patent No. 1274859, dated August 6, 1918. Such class of machines is characterized by the inclusion of a plurality of tool carriers and work carriers, which are relatively indexed in step by step movements to bring the work successively into operative relation with the various tools and at each station a relative movement between the tools and work is effected, preferably by feed of the tools, to simultaneously perform a plurality of operations. Such machines are further characterized by the provision of mechanism which automatically regulates and controls the various, movements in a predetermined manner, The primary object of the present invention is to provide an automatic multiple spindle metal working machine of the character described, of novel construction, designed to obtain a most efficient means for machining parts in large quantities, with the use of semiskilled labor to operate the machine after it is set up and timed for the various operations, thus offsetting increasing labor costs and effectually meeting the need for increased production. Claim: In a multiple spindle machine of the character described having a work carrier and a multiple spindle tool carrier, mechanism for relatively moving said carriers in rapid approach, feed and reverse movements, mechanism for indexing one of the carriers, control mechanism for automatically causing the first mentioned mechanism to produce said rapid approach, feed and reverse movements in predetermined relation, and means operable at the will of an operator for causing the first mentioned mechanism, during control thereof by said control mechanism, to function different from the predetermined automatic operator.
