IMPROVED SHAG CUTTER. 



larged views of the head of the churn staff. ABDE fig. 7, 

 is a section of the churn ; FG is the lid; KL is the churn 

 staff, and HI the wings, or beaters; it is this part only 

 which differs from the ordinary churn; it consists of four 

 wings or vanes MNOP, fig. 5, tirmly fixed together, and 

 turning freely on a pin driven into the end of the churn 

 staff. The flat part of each vane is cut, so as to be inclined 

 to the plane in which all four lie, in the same manner as 

 the sails of a windmill, as is well explained by figs. 5 and 6. 

 When the beater is moved up and down through the cream, 

 its action upon the oblique vanes causes it to turn round 

 upon a pin above mentioned, as a centre, a, Fig. 7> is a 

 small wooden bolt sliding in a groove made in the churn 

 staff, KL; its end shuts into a hole 6, fig. 5, made in one 

 of the vanes; when this bolt is pu(hed down, it prevents the 

 vanes from turning round, for the purpose of collecting the 

 butter together at the top of the butter-milk when the 

 churning is done.

Improvement in Cutting Sifk Shag Edgings: by Mr. Pe* 

 ter Tansley, at the White Horse, Wheeler Street, Spi~ 

 talftelds*. 



SIR, 



Narrow *hag Jl N the latter end of March, 1806, my employer, Mr. Jef- 

 tedious to cut f frv f g ow Lane, Cheapside, applied to me with a pattern 

 nion in»p!e- of & i'k shag, about six eighths of an inch wide, which he 

 roent, wished to be executed as quick as possible. 



Being aware how tedious an operation it was tp cut the 

 shag with the trivat, the instrument generally used by the 

 shag weavers for that purpose, I thought I could invent an 

 instrument, which would cut it in one third of the usual 

 time; I therefore drew the plan of one, and gave it to Mr. 



» Trans, of the Soc. of Arts, vol. XXVI, p. 164. Five guineas 

 were voted to Mr. Tansley tor this invention.
