Flooring and bench cramp; machine for mortising wood; lifting jack
THE FOLLOWING ARE EXHIBITED:--
MORTISING MACHINE. This works upon a different and more powerful principle than any other mortising machine yet introduced. The power is obtained by an eccentric wheel working in a rack at the back of the slide, whereby greater leverage is obtained.
BISSELL'S PATENT FLOORING CRAMP. The force of this cramp is fully equal to 1 ton. It is adapted to joists from 2 to 4 in. and is the most expeditious and easy in working of any cramp in use.
BISSELL'S COMBINED LIFTING JACK.
