frame is to be kept together, and tightened, by iron rods with heads, 

 screws, and nuts. 



This machine, in its general features, bears a strong resemblance 

 to others which have been heretofore used ; the patentees say, 

 " what we claim as new, and as our own invention, in the above 

 described machine, is the operation of the open cjlii^der, and the 

 manner of fixing in those slanting slats, to carry the water to every 

 part of the machine, to serve as drenchers ; also the iron rods that 

 fasten the frame together." [/6.

The main object of this invention appears to be the turning of 

 both miil-slones in opposite directions ; as this is not new, the 

 claim of the patentee must r-^st upon the manner of eiTecling this 

 object. A vertical wheel, with cogs upon its face, works into two 

 vertical trundles at its upper and lower points, aind, of course, turns 

 them in opposite directions. These trundles are attached to the 

 spindles of the upper and lower stones, and (he desired motion is 

 thus attained. The manner of attaching the spindles, and hanging 

 the stones, we do not think it necessary to describe. The patentee 

 says, " what 1 claim as new, and as my invention, or discovery, in 

 the above described grist-mill, is (he use, or apphcatioii of the 

 whole machine, vvith the exception of the two main wheels, and 

 the wallower in the horse-mill." [/6. 



Specijjcation of a Patent for a Socket Vice. Granted to Lutker 

 Hemminvvav, of Suil'vayi, Cheshire County, J>fe20- Hampshire, 

 September 4. 1828. 



The socket vice may be made of any size, according to (he use 

 to which it is to be applied, and of metal or wood. When made 

 to be used as a socket for awl'^, it should be of steel ; its whole 

 Jength should be about two inches and three-fourths ; one end, for 

 about three-fourths of an inch, should be round, and about one- 

 fourth of an inch in diameter; beginning three-eighths of an inch 

 from the end, it should taper slightly to the end, upon which, for 

 the same distance, a screw should be cut ; it should then diminish, 

 and again increase in diameter, in both cases slightly, and i;radual- 

 Jy ; at three-fourths of an inch from the end it is flattened abruptly, 

 forming a shoulder on two sides, and is made tapering on the two 

 edges, to the other end, where it is pointed ; a hole is made longi- 

 tudinally into the round end. about three-fourths of an inch deep ; 

 it is then cut twice transversely, from the end to the bottom of the 

 hole, dividing it into four equal parts ; a hollow screw, or nut, 

 adapted lo the vice, is screwed upon this end, compressing it so as 

 to hold, firmly, the shank of the awl ; the outside shape of the nut
