XIII. Defeription of the Mangle invented by Mr. Jun.. Ex- 
traéied from the Tranfactions of the Society for the En- 
couragement of Arts, &c.* Vel. XVI. 
Ta IS mangle (fee Plate XI.) is fo conftru&ted that the 
handle is required to be turned one way orly, which moves 
the machine more fteadily and fafer for the linen, than by 
varying the turning of the handle. hy 
Fig. 1, is a perfpetive view of the mangle when at work. 
The letters of reference anfwer to the fame parts as in 
fig. 2; but here the great wheel is hid’ by a board which 
lies on the frame B. 
A, fig. 2, is the great atid 15 inches in diameter, the 
teeth of which, being on the under fide, cannot be feen-in 
this view; B is the arbor on which the pinion C is faftened, 
which is worked by the winch D. The pinion caufing the 
large wheel to revolve, works the crank EF, (the part E is 
21 inches long) which being faftened to the moveable bed 
K by a pivot at G caufes it to move forward and backward,, 
by one continued motion of the winch, guided in its place 
by the pulleys III1I. HH are two levers for raifing the 
bed to put in or take out the linen which is wound on the 
rollers LL: this is effected by the open ftuds GG at the 
ends of the bed being brought alternately over the ends H 
of the levers, the other ends of which are then preffed down 
by the hand. 
Fig. 3 is a front view of one of the open ftuds. 
* In confideration of the merit of this invention, the Society voted their 
filver medal to Mr. Jee. Two complete models are referyed in their 
Frepofitory for the ufe of the public.
