means the combustion of the contained fuel, may 

 be completely controlled, and but little, or no con- 

 sumption take place, whatever may be the quan- 

 tity within the stove. That such a stove cannot, 

 and must not, be made perfectly air-tight, will be 

 at once adnntted, and we are not aware at what 

 degree of good fitting, the allair would be entitled 

 to a patent. We have a stove in which the de- 

 sign was to make the doors, and the ash drawer, 

 fit as closely as possible, so that the fire might be 

 regulated by the drawing out, or closing, of the 

 latter; this is one of Spoor's, ;ind there are many 

 others similarly constructed in this respect, and in 

 which, were the workmanship made a little more 

 perfect, without any change of structure, all that 

 Mr. Orr proposes from this arrangement would be 

 accomplished. 



In addition to the close doors, the patentee has 

 grate bars placed under the fiiel, resembling the 

 revolving vertical dampers, or valves, used in some 

 stoves, and consisting of two plates with openings, 

 which may be made to coincide, or which may be 

 closed by the unperforated parts. If we do not 

 greatly err, such a grate will be obstructed by the 

 coal, and choaked by the ashes. There may be 

 enough in some of the individual arrangements 

 pointed out, upon which to found and sustain a 

 claim, but they are not made to stand alone, and 

 it is not in our power to put them iu a situation to 

 do so. 



Yor 3. Portable Reflecting Baker; Lorenzo B. 

 Olmstead, Bintrhamton, Broom county, New 

 Yoric, January 20. 



This tin baker is to be heated by means of a 

 cylinder of sheet-iron, which is to contain ignited 

 charcoal, and to pass vertically down through the 

 back of the box which constitutes the baker. This 

 latter is a kind of eight sided oven, the top being 

 ridged like a roof^ and the bottom in the same form 

 inverted, the back circular, and the front, which 

 lifls off, being straight ; we mention these things 

 because the peculiar form is claimed. The arti- 

 cles to be baked are put into pans, which stand on 

 wires within the baker, and the fire being kindled, 

 and the front reflector affixed in its place, we are 

 assured that the desired operation will be "per- 

 formed sooner than in any iaiown oven or baker, 

 with an immense saving of fuel." 



For a Thrashing Slachine ; Eleazer Brown, 

 Chenango, Broom county, New York, Janua- 

 ry 20. 



This thrashing machine consists of a hollow 

 cylinder about three feet in diameter; its length is 

 not mentioned, but from the drawing, we should 

 suppose it to be, at least, twelve feet. It stands 

 horizontally in a frame, and within it revolves a 

 shaft, which carries tour, or any other number of 

 rows of wooden beaters. The grain is fed into 

 the cylinder through an opening in its side, near 

 to one end, which is closed, the other being left 

 open. On the shaft near the closed end are spiral 

 fan leaves, which force a current of air through 

 the cylinder. The patentee says that "the rapid 

 motion of the shaft separates the grain, and the 

 strong current of air driven through the cylinder 

 by the fans, carries out the straw and grain." 

 There is no claim made, the general construction 

 being probably considered as new, which we be- 

 lieve it is. 



For a Horse- P 010 er ; Samuel Newton, Dayton, 

 JMonlgomcry county, Ohio, January 20. 



This horse power is one of that kind which re- 

 ceives its impulse from the walking of the horse, 

 or other animal, upon an inclined Hoor forming a 

 chain of slats, the patentee calls it the "Friction 

 Obviator, or Double Chain Horse-Power," in 

 which is combined the joint application of two 

 continuous, or endless, chains. The second of 

 these endless chains consists of rollers connected 

 by suitable straps, which sustain the movable 

 floor by running upon a suitable railway under it, 

 the part not so employed hanging down beneath 

 the floor. After a full description of the appara- 

 tus a claim is made to "the particular manner of 

 constructing the fi'iction chain," &c. We could re- 

 fer to several patents taken in the United States, for 

 a perfectly similar contrivance; but will go farther 

 back than any of these, and look in the second 

 volume of the first series of the Repertory of 

 Arts, p. 366, where we find the same nmchine de- 

 scribed and figured, having been patented in Eng- 

 land, in January, 1795. 



For a Plough; John P. Chandler and Peter 

 Ramjer, Wilton, Kennebeck, iVlaine, January 20. 



We have, for brevity's sake, called this a 

 |)lough, but the patentees denominate it a "Ma- 

 chine for ploughing land," and indeed from its com- 

 plexity it appears to require some such appellation. 

 It has an axletree and two wheels, like a cart, 

 with a frame somewhat like that of a cart body, 

 sustaining a tongue to which to attach the horses, 

 together with other appendages. Under this 

 frame there are to be three ploughs abreast, all of 

 which are to be managed, by means of levers and 

 suspending chains, by a person seated on the ma- 

 chine; the ploughs being so suspended that they 

 can be raised or lowered at pleasure. The claim 

 made is to "the using of two or more ploughs at 

 the same time, and with the same team ; and also 

 having the plough suspended so as to have the 

 weiffht of it carried on wheels." The patentees 

 might, probably, sustain a claim to their own 

 mode of doing these things, but double ploughs 

 have of^en been used, and wheeled ploughs are re- 

 presented in the books, and are common in Eu- 

 rope. 



For a Corn Sheller; Warren Carpenter, New 

 Castle, Mercer count}', Pennsylvania, January 23. 



A plank is to be slid up and down between two 

 cheeks, grooved for that purpose; into each side 

 of this plank iron pins are driven, which project 

 out a short distance. The corn to be shelled is to be 

 dropped in between this slide, and two pieces of 

 plank near the lower end of the frame, which are 

 borne up towards the slides by springs; these 

 spring pieces of plank are armed with teeth, like 

 the slide. The slide is to be worked up and down 

 by hand. The claim made is to "the particular 

 structure, combination and arrangement of the re- 

 spective parts." 



For a Machine for Packing Flovr in Barrels; 

 Jonathan F. Barrett, Granville, Washington coun- 

 ty, New York, January 23. 



This is certainly a new, and, we think, a good 

 machine. The flour to be pressed, runs into the 

 barrel in a continuous stream, and the pressing 

 commences at the bottom, and goes on until the
