For Making Jirtificial Stone or Marbh; Oba- 

 diah Parker, city ol" New York, September 9. 



Pulverized granite, or pulverized marble is to 

 be brought, to a pro|)er consistence Ibr moulding 

 into the required turin, in combination vviih water 

 'ime. This constitutes the inveniian. 



For the Formation of yjrtijicial Stone and Mar- 

 ble for j/rchitaciarnl Purposes; Obadiuh Parker, 

 ciiy of New York, S "ptember 9. 



We have agam about a dozen page? devoted to 

 the mode of forming various ornamental and use- 

 ful articles, pavements, &c. &c. by modes analo- 

 gous to those described in the preceding specifica- 

 tions, and having consequently, the same claim to 

 novelty, or rather to antiquity. Should the paten- 

 tee think himself aggrieved by the ibregoing re- 

 marks, a thing which we do not anticipate, we 

 will ofl'er him a reference to a gentleman in New 

 York, who can tell him much more about the 

 combinations of water lime, and the formation ol 

 artificial stone,than he now knows; and will give him 

 ample proof that our animadversions, or rather in- 

 timations, are founded in jierlect truth. 



For a TVater JVheel; Jehiel W.'Darl, and Ste- 

 phen Wood, Truxton, Cortland county, New 

 York, Septembar 9. 



This is a kind of re-action apparatus, in which 

 two wheels difilsrently constructed are to be placed 

 one close above the other on the same vertical shaft; 

 the first of these wheels has tour floats which re- 

 volve ill a circular drum, through the side of which 

 the water enters tangenticall^' to the circle, and 

 strikes the floats: after performing its labor there, 

 it escapes through a centre hole in a horizontal 

 partition, and enters the ordinary reaction wheel, 

 passing through its curved channels, and escap- 

 ing at its periphery. 



The claim is to "the increase of power which 

 is obtained in the above arrangement of the cen- 

 tral discharges, or whirlpool wheel, and the reac- 

 tion wheel." This is rather an inverted claim, 

 being to the end, instead of to the means; but this 

 in the present case is a thing of little conse- 

 quence. 



For an improvement in the Coffee and Corn 

 Mill; Elijah Morse, and Caleb Putnam, Knox- 

 ville, Tennessee, September 9. 



Nominal improvements are so easily made that 

 it requires no talent whatever to be author oi 

 them, and such is that which forms the subject of 

 the present patent. The mill in which the pre- 

 tended improvement is made, is the common cast 

 iron mill with a conical shell and nut, in its unal- 

 tered state, excepting only that the patentees 

 "claim as their own invention, and not previously 

 known in the above machine, that the furrows in 

 their mill run straight through, and not spiral, as in 

 all other mills." It does not require two grains of 

 mechanical knowledge to enable a person To decide 

 that this change deteriorates instead of improves 

 the mill: nor is it necessary to have dipped deeply 

 into the logic of Aristotle, or of Watts, to arrive 

 at the conclusion that it requires one and one to 

 make two, yet in the case before us we are to ad- 

 mit that the inventive genius of two individuals 

 might be_ put into requisition to devise one set of 

 etraight furrows. 



For Supplying and Regulating the Draught of 



AW to Fire Places; Robert Mayo, city of Wash- 

 ington, September 9. 



Pipes, or tubes, of tin, or other material, which 

 may be from one and a half to three inches in di- 

 ameter, are to lead from the lower part of a build- 

 ing, up the outer walls, their upper ends opening 

 under the grate or fire place. Such pipes may be 

 added to buildings already erected; but in the 

 erection of new ones it is proposed to form these 

 ascending air channels within the thickness of the 

 walls, their lower ends opening to the external air, 

 and their inner to the fire place. Valves to regu- 

 late the quantit}^ of air admitted, may be con- 

 structed of any suitable form. 



The claims made are '■^Flrst. The arrange- 

 ment, combination ol" parts, and adaptation of tlie 

 air pipes, or tubes, to ascend the outer walls or 

 chimneys of buildings, or apartments, and pene- 

 trate the same, contiguous to fire places. Second. 

 I claim the construction of air channels or flues in 

 the masonry of chimne3's, or the walls of build- 

 ings, to ascend from a lower stratum of atmos- 

 phere and terminate near to, or in, the fire 

 places." 



With the exception of extending the tubes to 

 the lower part of a building, it will not be pretend- 

 ed that there is any novelty in this contrivance, the 

 practice of admitting air from without, to feed fires, 

 being old and common; but even the ascending 

 tubes themselves are not new, they having been 

 frequently recommended and applied to the sup- 

 ply of fires for the purpose of ventilating cellars, 

 and other lower apartments; it may be said, how- 

 ever, in the present case, that this is not their ob- 

 ject, that object beingmerely the supply of the fire; 

 without inquiring into the validity of this allega- 

 tion, it is proper to ask what are the advantages of 

 these descending pipes, and we believe that this is 

 a question which cannot be satisfiicforily answer- 

 ed. The patentee says that we shall "thereby 

 create a constant current through the tube, or 

 pipe, of a strength proportionate to the height of 

 the pipe, or the greater weight of the medium of 

 atmosphere at the lower extremity, or inlet, than 

 that at its upper extremity, or outlet; which takes 

 place upon the same principle of pneumatic or at- 

 mospheric pressure, which forces water in a tube, or 

 well, to rise to the height indicated by the known 

 weight of the atmosphere: and this principle is 

 equally applicable, of course, to the air channeisj 

 or flues, constructed in the masonry." 



The foregoing may pass with the illiterate for 

 good reasoning, but it is altogether false and un- 

 founded. The pressure at the opening of the 

 tube within the room will not be altered by the ex- 

 tra height of the atmosphere above the lower 

 opening, the column within the tube being a per- 

 fect balance to this; the whole trouble and expense 

 of the tubes may, therefore, be saved, together 

 with the cost of a patent right to do that which is 

 in itself altogether useless. 



For a Washing Machine; Jami?s Lombard, 

 Readfield, Kennebec county Maine, Septem- 

 ber 9. 



The trough of this machine is a concave semi- 

 cylinder, closed at the ends, and fluted along the 

 semicircular part. The rubber, which is to act 

 upon the clothes, is also a semi-cylinder, which 

 passes into the trough, and is suspended by an 

 axis at, or near, its centre. This rubber is either 

 fluted, or covered with fluted rollers, passing from
