For Backs of Stoves and Fire Places ; Wil- 

 liam R. Prescott, Hallowell, Kennebec county, 

 Maine, March 19. 



A tulie of suitable diameter, say nine inches, 

 and two or three feet loiiii;, is to be built in the 

 back of a fire place, or fixed, in any convenent 

 way, in a stove ; a tube, of about two inches di- 

 ameter, is to lead from without the room, into this 

 longer tube, to supply it with cold air, and warm 

 air tubes are to lead from either end of it, into the 

 room, to afibrd a supply of warm air. 



The claim is "to bringing, in the manner de- 

 scribed, the cold air fi'om without the room to 

 which the fire place is situated and suppl^vinji it to 

 the stove, and of thus keeping up a circulation of 

 cold air from without, and of" warm air into the 

 roofli. The application of the apparatus described 

 for fire places, stoves, and fire frames, for the pur- 

 pose of warming rooms, and its general construc- 

 tion." 



Whilst there is nothing new in this principle, 

 the form pointed out for carrying it into effect 

 would be one of the least efficient ; the "general 

 construction" is so ge[ieral,'and so extensively em- 

 jiloyed, that it is a little remarkable it should be 

 claimed as new. 



For Preserving Milk for use on Joyages, Sfc. ; 

 John Lewis Granger, city of New York, March 

 19. 



Fresh milk is to be put into botiles, and these 

 are to be closed, in the manner of corking, with 

 some porus substance, which will allow air to pass 

 through it ; the bottles are then to be put into a 

 vessel of cold water, and the whole gradually 

 lieated to the boiling point, alter which the porous 

 stopper is to be coverd with wax. 



The claim is " to the evolving of gas. and suf- 

 ferino; it lo escape from the milk, and immediately 

 afterwards excluding the atmospheric air from 

 commingling therewith, by the method substan- 

 tially as described." 



We apprehend that the theory above intimated, 

 namely, that the gas contained in milk is the 

 cause of its spontaneous decomposition, is not 

 founded in fact ; were this the case, an exhausted 

 receiver would as effectually efi'ect the object in 

 view, as the boiling heat, and this process would 

 not be substantially as described." There is a 

 chemical change produced in milk by boiling, bj' 

 which its liability to liirther reaction is very 

 much diminished, and which would not be pro- 

 duced by the mere expulsion of gas. This theo- 

 retical point, we are aware, has nothing to do with 

 the validity of the claim, although we have 

 thought proper to give it a passing notice ; we 

 have also somethins; to say about the novelty of 

 the process. In the celebrated report published 

 by the French Government in 1810, on Mr. Ap- 

 pert's mode of preserving all kinds of animal and 

 vegetable substances, milk is mentioned as having 

 been preserved by boiling and corking closely ; it 

 was concentrated in the boiling by allowing a por- 

 tion of its watery particles to evaporate ; the pro- 

 cess was, we think, substantially the same with 

 the above, the principle of which was perfectly 

 well known. 



For a Cider 3fill ; Christian Sheaffer, Leba- 

 non, Lebanon county, Pennsylvania, March 19. 

 This cider mill is to grind the apples by means 



of revolving nuts or, toothed cylinders, of which 

 there are three, mashing into each other. All tlie 

 novelty appears to be in' the manner of building 

 the mill. We are told that "the machine consists 

 of tvvophir of stairs, a frame, an apple mill made 

 of three cog wheels ; cage or receiver, a pre?s 

 beam, two main screws, one assistant screw; two 

 weight boxes, &c. &c." After describing the two 

 pair of stairs, and the other component parts of 

 the machine, it is said, " I claim as my invention 

 the wliole of the machinery, excepting what I 

 have named the cage or receiver; the bed or bo.x 

 belonging to the cage or receiver, and the .manner 

 of mixing the straw with the o-round apples, or 

 rather the smashed apples." This claim to the 

 whole machinery, cannot be understood to mean 

 the machinery as a whole, but as applying to its 

 component parts individually ; scarcely one indi- 

 vidual of which could bear the burden thus put 

 upon it, without being smashed. 



For a Cooking Stove Grate, and its appenda- 

 ges; Orrin Wilson, Concord, Middlesex county, 

 Massachusetts, March 23. 



The grate to contain the coal, or wood, is made 

 with bars, and, in general, like the ordinary grate 

 of an open fire place ; but it is so affixed to a cook- 

 ing stove, with ovens, or other desired appenda- 

 ges, as that it may be raised vertically, so as to 

 communicate its heat rnore directly to the cooking 

 department, or lowered so as to form an open 

 stove. Above the grate, a windlass crosses, near 

 th6 front of the stove, and four chains attached to 

 this windlass, and to the four corners of the grate, 

 serve to raise and lower the latter, as may be de- 

 sired. 



The claim is to "the moveable grate, or pan, 

 whether operated with chains and pulleys, rack 

 and pinion, or other mechanical powers; the pe- 

 culiar adaptation, arrangement, and combination 

 ol^' the several parts of the stove, fire fi-ame, or 

 fire place, to the said moveable grate, for the uses 

 and purposes herein described and set forth." 



For a Stove, denominated the Sibelline Stove ; 

 Wm. M. Carmichael, Hempstead, Queens coun- 

 ty. New York, March 23. 



A cylindrical stove, lined with fireclay, is made 

 in the usual manner. The stove is to be sur- 

 rounded by a second cylinder, lea^ving an air cham- 

 ber between the two, with a|)ertures below lo ad- 

 mit cold, and others above to discharge warm, 

 air. The whole stove is to stand upon a drum, or 

 pedestal, of a diameter considerably larger than 

 the stove itselfj and is to be surmounted by ano- 

 ther drum, or hollow dome, elevated a few inches 

 above its top ; a smoke pipe from the centre 

 of the top of the stove, conducts the smoke 

 into the drum. Four, or more, hollow columns, 

 connect the two drums, surrounding, but detached 

 from, the body of the stove; these columns form 

 flues between the two drums, and from one of 

 them a smoke pipe leads into a chimney, there 

 being a damper in the column, above the smoke 

 pipe. When this damper is open, the smoke and 

 heated air pass directly through the upper part of 

 the column, and into the exit pipe. When the 

 damper is closed, the draught has then to pass 

 down the three open columns into the lower drum, 

 and up the fourth to the smoke pipe.
