JYo. 1845 — Trom Block for Flour Mills a7id Xoddlc Pin for 



Saw Mills. 

 Gideon Hotchkiss, Windsor, Broome co., N. Y. The tram block 

 is a very great improvement upon the old system of bridge tree, 

 insuring a perpendicular lifting of the spindle. A large socket 

 is placed in the lever, and is perfectly under the control of the 

 miller. The grinding can be done with more certainty as to 

 evenness than in the common way. Millers have long been in 

 need of something like this present apparatus, which has no 

 parallel for simplicity and efficiency. The flouring mills of 

 Eichmond, Boston, Wilmington, Rochester, &:c., have adopted 

 it. The universal joint noddle pin for saw mills, is a very use- 

 ful and simple fixture, used extensively for the upper end of the 

 pitman in saw mills. [A silver medal awarded. 



J\^o. 1440 — Adjustihle Mill Pick. 

 H. T. Hyde, Troy, N. Y. A very convenient and economical 

 tool, [^ diploma awarded. 



Grain Mill. 

 W. P. Coleman, New Orleans, La. This is a portable grist mill, 

 with small horizontal perch burr stone, the lower stone being 

 the runner, and balanced on the spindle. The workmanship 

 and whole getting up is superior; it grinds with great rapidity 

 and evenness. The best for plantation common use. 



\^A silver Tnedal awarded. 

 JYo. 231 — Grain and Flour Mill. 

 Prentiss & Page, 8 Seventh avenue. These mills have long been 

 known, and fully secured the confidence of the public. They 

 are well suited for making flour, grinding feed, &c. The second 

 best. ■ ^A diploma awarded. 



Mo. liO—Cob a7id Corn Mill. 

 Troy Portable Grain Mill Company, Troy, N. Y. The working 

 parts of this mill are made of cast iron so arranged as to be easily 

 and cheaply renewed, grinding grain of all kinds, corn and cob, 

 with great rapidity, and witli a small amount of power. It is 

 also anti-choking, and grinds oats, without mixture with other 

 grains. The best as a corn and cob mill. 



[A silver medal aumrded. 



JYos. 1493, 1494 a7id 1848— TArce Co?iical Burr Stone Mills. 



Ross & Davis, Rochester, N.Y. These mills are well arranged, and 



show good workmanship in their getting up ; but conical forms, 



in our opinion, are far inferior to the flat. [A diploma awarded.
