Assigned to B. K. Sweeney Mfg. Co. - Denver CO

"This invention relates to a torque indicating wrench for accurately tightening threaded elements such as, bolts, nuts, studs, screws, etc. to a uniform predetermined tightness." "One of the principal objects of this invention is to provide the torque scale of a torque indicating wrench with a simple and highly efficient reading-retaining device which will -travel along the torque scale when force is being applied to the wrench and which will retain its maximum force position when the force is released so as to make it unnecessary for the operator to keep his eyes on the scale while exerting force on the wrench. He can make all the necessary force adjustments of the threaded element to attain the tightness desired by inspection of the position of the reading-retaining device at his convenience." "Another object of this invention is to provide a sturdy, relatively simple, and exceedingly accurate wrench construction which will, when a preset torque is reached will give a positive, sensitive mechanical signal to the hand of the operator so that the application of force can be stopped at the exact preset point. without reference to the scale." B.K. Sweeney Mfg. Co. produced specialty tools including torque wrenches, torque testers, etc.

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.
