Description:
Munn & Co.- patent attorneys

The invention relates to machinery for circling barrel-heads by revolving clamps and a circular saw, the clamps being contrived to move the pieces to be sawed up to the saw, and turn them around one revolution, and then move away at the same time that they open to discharge the finished head; and it consists of the apparatus for gearing the shaft of the clamps with the saw-arbor to turn it thereby; also the apparatus for closing and opening the clamps; also mechanism for starting, stopping, and allowing the clamps to rest for changing the work; and also mechanism for causing the clamps to turn a little more than a revolution at each operation in combination with an automatic stop, to insure the cutting of the complete circle, all as hereinafter described.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent—

1. The combination of a tripping-wheel, a, with the clamp-shaft and the trip-catch, the said wheel having slower motion than the clamp-shaft, substantially as specified.

2. The combination of the pinion, and tripping-wheel, with the driving-shaft, and the clamp-shaft, substantially as specified.

3. The swinging rod, combined with and jointed to the swinging clamp-shaft, substantially as specified.

4. The swinging rod, having lengthwise motion in its support, and the spring, in combination with the clamp-shaft, substantially as specified.
