Shuttle picker made of vulcanised rubber, the use of which was patented in 1857, unknown maker.

To drive the shuttle of an ordinary calico loom, a blow of about three foot- pounds must be struck for each throw, and this energy is transmitted to the shuttle by the picker. At even an ordinary speed of 200 picks per min., the wear upon the picker is serious, so that many materials have been tried in place of buffalo hide, the material most generally employed. The picker shown is made of hard vulcanised rubber.
