The inclined table is employed for feeding,` the material'to the rolls and may be in connection with the open end of a Wool-Washing` tank or otherwise.

Vhat we claim is- 1. The combination of a fixed and a movable roller, a frame on which the saine are mounted, movable bearings for the movable roller, upright pivoted levers, link connections between the said levers and the movable bearings, a shaft mounted on the said frame, pulleys carried by the said shaft, quadrantlevers connected to the pulleys, flexible connections between the upright levers and the said pulleys, flexible connections attached to the quadrant-levers, weights carried by the said connections, and means for raising the weights and adjusting the pressure between the rollers aforesaid, substantially as described.

2. The combination of a fixed and a mov# able roller with a frame on which the said rollers are mounted, movable bearings for the movable roller, upright pivoted levers, link connection between said levers and the movable bearings, a horizontal shaft carried by the aforesaid frame, pulleys carried by the said shaft, weighted quadrant-levers connected to the said pulleys and mounted on the same shaft, flexible connection between the said pulleys and the upright levers, resilient bearing` between the upright lever and its connection with the pulleys, means for regulating the tension of said connection, weights connected to the said quadrant-levers, means for raising the said weights consisting of a cylinder connected to the aforesaid pulley by ilexible connection, a wormwheel and worm-shaft for operating the same, substantially as described.

Iniestiinony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
