For an improvement in Saw Mills; George 

 W. Black, Montgomery county, Tennessee, Feb- 

 ruary 3. 



The object in constructmg ihii? mill is to apply 

 the power above the surlace of the ground. The 

 main cog wheel, driven by any suitable power, 

 gears in'o a pinion on a pitman shaft above the 

 sills, the pitman extending thence to a rocking 

 shall which gives motion to a saw frame, hung in 

 the usual way. The claim is to the horizontal 

 pitman and its apurtenances, including " the en- 

 tire mode of driving the saw, or saws, and the 

 mode ot ajipljing the power to them," in which 

 the patentee perceives numerous advantages, 

 which we apprehend will not be realized m many 

 situations, and no where, assuredly, where water 

 power is employed. 



For a Straw Cutter; Isaac S. Wright, El- 

 bridge, Onondaga countj'. New York, February 

 3. (See specification.) 



For a Machine for Harvesting, Thrashing, and 

 Cleaning Grain; Eliakim Briggs and George 

 W. Carpenter, Covington, Franklin county, New 

 York, February 5. 



This machine is to run on four wheels, like wa- 

 gon wheels, the adhesion of the hind wheels to 

 the ground carrying revolving scythes, a cylinder 

 thrashing machine, and other apurtenances. The 

 apparatus is not fully described, and we are very 

 apprehensive that it had not been fairly tried be- 

 fore bemg patented, as we are of opinion ihat its 

 promise upon paper would not be realized in the 

 wheat field. Its power, to cut, conve}', thrash, and 

 clean grain, and the satisfactory concurrent action 

 of all its parts, would not, we think, have given it 

 a passport to the Patent Office. 



The claim is to ''the manner and principles of 

 applying the power of a team to cutting, thrash- 

 ing, and cleaning grain, by moving Ibrward the 

 machine; of cutting grain, of carrying it to the 

 thrasher, of thrashing, and of cleaning grain, by 

 power so applied." This claim does not, with 

 sufficient distinctness, state the pariicular machine- 

 ry for effecting the object, refers to no individual 

 part of it, but appears to relate more to the end 

 than to the means, whilst the latter is the only 

 thing patentable. 



For a. Horse Rake for Hay and Grain; Joseph 

 W. Webb, Mount Morris, Livingston county. 

 New York, February 5. 



Behind an axeltree with two wheels, there is a 

 frame which sustains the rake-franie, and the lat- 

 ter slides up and down between cheeks, furnished 

 with grooves for that purpose ; upon the bottom 

 edge of the rake-frame are teeth, curved forward 

 and reaching to the ground ; a man stationed on 

 a platform above the- axel free, raises the rake- 

 frame by means of a lever, when it has collected 

 the desired quantit}', and thus depositcs it. The 

 points of the rake teeth curve back suddenly to 

 prevent their catching in the ground. The claim 

 is to "the manner of laising or depressing the 

 rake at pleasure, by means of the perpendicular 

 grooves and the lever; and the mannerof curving 

 the teeth backwards, for the purpose set forth." 



For a Machine for cleaning smut from Buck- 



wheat and Rice; Samuel Richardson, Elmira, 

 Tioga county. New York, February 5. 



It is very well that the patentee sets forth no 

 exclusive claim to this niacfiine, as, were he to 

 do so, he woidd encounter a host of competitors. 

 The whole consists of a hollow cast-iron cone, in 

 which runs a conical nut, both properly grooved, 

 m the well known old coffee mill fashion. 



For a Press for Cotton, Tobacco, 8fc.; Azel 

 IM. McLean, Russelville, Logan county, Ken- 

 tucky, February 5. 



This press consists of a lever working on a ful- 

 crum t)etween two upright posts, the articles to be 

 pressed being placed under the lever, and resting 

 on sills, or a |)lailbrm on the ground. A rack and 

 pinion below the long end ol' the lever serves to 

 raise or lower it ; and the improvement claimed 

 consists in extending the lever beyond the up- 

 rights, so that it shall have a short arm projectmg 

 out far enough to press the articles by the eleva- 

 tion of the loiig arm, as they are pressed on the op- 

 posite siile by its depression. 



For a Horse Power; Dudley Marvin, Canan- 

 daigua, Ontario county. New York, February' 5. 



This machine is, in its general construction, like 

 many which have preceded it, consisting of an 

 endless chain floor upon which the animal walks, 

 which floor is sustained by Iriction rollers running 

 upon ways, and connected so as to Ibrm endless 

 chains ; it is the peculiar manner in which these 

 are put together, upon which the patentee must 

 depend to sustain a claim, and he says, " I confine 

 my claim to the particular manner in which I con- 

 siruct the power chain, and the Iriction chain, as 

 described, together with their combination with 

 those accessory parts which are necessary to their 

 action. I do not claim either of the individual 

 parts as separate and uncombined." 



For a Churn; Hezekiah Roberts, Seneca 

 Falls, Seneca county. New York, February 5. 



A vertical churn is to have the dasher made to 

 revolve alternately in reversed directions, by 

 means of a double strap, the two ends of which 

 are wound round the shalt, and are alternately 

 acted upon. To produce this motion, the patentee 

 employs a wheel and pinion, on the shaft of the 

 latter of which there is a crank and fly wheel. A 

 pitman from the crank is made to vibrate a wheel 

 which communicates the alternating revolution by 

 means of the straps. The claim is to " the crank, 

 connecting rod, spur wheel, pinion, and balance 

 wheel." All of which are well known affairs. 



For an improvement in the Process of prepar- 

 ing bark and obtaining the extract therefrom ; 

 Daniel Williams, Boston, Massachusetts, Febru- 

 ary &. 



We are infJjrmed that the bark is to be first di- 

 vested of its outer part, after which the inner bark 

 is to be cut into small pieces, and the tanning 

 principle extracted thereii'om by boiling, or by 

 steam ; the water is then evaporated and the ex- 

 tract fit for use. The thing claimed is the ex- 

 tracting tannin Irom the inner bark cut into pieces, 

 instead of grinding or pulverizing it, by which 

 means, it is said, the extract is more pure, being 

 free from the admixture of the minute particles
