^() MACHINE FOR CLEARING ROAD^. 



Machine for of the hand upon the pole tends to make the machnie fteady, 

 from mudf ^ ''^'""^ therefore caufes it to work to more advantage. In the 

 iiKxlel, the pole is made only ten inches long, inftead of fif- 

 teen, (hat it might occupy lefs fpace in the box. The plates 

 in front of the fcraper, and upon the fledge, are made of 

 call- iron. 



Operation. 



For the operation of the machine^ two men and four horfes 

 are required : one man to drive the horfes, and another to take 

 the management of the pole and the dire6lion of the labour 

 to be performed. The horfes are to be worked double, as 

 commonly pra6lifed, two being employed to draw by the 

 fliafts, and two by the chain above defcribed. But the manner 

 of ufing the machine will be beft underftood by the following 

 flietch. Flute I. Fig. 3. 



The firft progrefs of the machine marked No. 1, commenc- 

 ing from the arrow-mark, will remove the mud in a linef to 

 the right ; the firfl: return. No. 2, will remove another part 

 of it to (he left. The fecond progrefs. No. 3, will take up 

 what is left by No. ), befides the quantify which is upon the 

 fpace now to be pafled over, and will remove it all to the 

 right. The fecond return. No. 4, will operate in a fimilar 

 manner with regard to No. 2, and remove that to the left. 

 Thus, by four lengths, more than twenty feet wide of a road 

 can be cleared ; and tliis has been frequently performed in the 

 prefence of feveral perfons. The number of lengths may be 

 jncreafed at plcafure, according to the width of the road. 



In the neighbourhood of London, where there is incefTant 

 travelling, it would be advifeable to ufe two machines at the 

 (ame time, one immediately following the other, as in No. 1 

 and 3, which will leave a fpace fufficiently wide for the 

 largeft carriage to pafs, without difturbing the mud already 

 Icraped up. 



There is one advantage in the operation of this machine 

 worthy of being noticed, which is, that by the ufe of it the 

 r(»ad is made more even and fmooth, the fmall holes being 

 fjiled up by the more folid parts of the mud ; whereas, when 

 roads are fcraped in the ufual way, by hand, all the irregu- 

 larities are increafed, and become the future depofits of water ; 

 and it is univerfally known that thefe puddles, as they are 

 called, are the chief caufe of the deftrudion of roads.
