6S Description of a Machine, &c. 



Reference to the Engraving of Mr. CleaWs Machine for heat- 

 ing out Hemp-seeds and Flax-seeds. Plate I. Fig. 1, 2. 



Fig. I. Represents the machine for beating out hemp- 

 seeds, in which A is the table or board on which the hemp 

 is to be placed ; B the axis in which the four arms, CCCC, 

 are fixed; DDDD, eight single flails, moving upon four 

 pins near the extremities of the four arms ; these flails di- 

 verge from the pins o.n which they move, so that two of 

 them united on each arm are nearly in the form of the let- 

 ter V. E is the winch or handle by which the machine is 

 put in motion ; FF, two upright pieces of wood to sustain 

 the axle of the machine; G, an upper cross-piece, to secure 

 the uprights firm; HH, the two bottom pieces or sills, in 

 which the two uprights are mortised, also the two smaller 

 uprights which support the board or table A ; 1 1, two lower 

 cross-pieces to secure the machine firmly ; KK, two levers 

 on which the table A rests, and by which it may be raised 

 or lowered as thought necessary by iron pins, at K K, pass- 

 ing through these levers and the two uprights. 



When the machine" is used, the hemp must be laid on 

 the table A, and moved about in different directions by the 

 person who holds it, whilst another person turns the ma- 

 chine by the handle E; the flails D of the machine fall in 

 succession on the hemp ; as the axis moves round they beat 

 out the set-ds as different surfaces of the hemp are exposed 

 on the table ; and when the seeds are all beaten out from 

 one parcel of hemp, a fresh quantity is applied upon the 

 table. 



Fig. 2. Represents one of the flax-beaters, which is made 

 of a solid piece of wood, one of which is attached instead 

 of the two flails, to every arm, when the machine is em- 

 ployed for beating out flax-seeds, as they require more force 

 to separate them from the flax plant.
