Cabinet Ware. A certificaté of honourable mention is awarded to James Kite, of Philadelphia, for specimen No. 145, a writing desk, made of a variety of Amer. ican woods, introduced with skill and good taste. There were several other specimens of cabinet ware exhibited, which, both in style and workmanship, were creditable to the makers, and fully sustained the character which Philadelphia has borne of preeminence in this branch of manufactures. Leather, and Manufactures of Leather. Premium No. 113, for the best specimens of white sheep skins, suitable for apothecaries' use, finished equal to that now imported from France, is awarded to Doyle & M'Neely, of Philadelphia, for specimen No. 506, two dozen skins, well got up. A certificate of honourable mention is awarded to Doyle & M'Neely, of Philadelphia, for specimen No. 305, two bundles of morocco boot leather, of very superior quality. A certificate of honourable mention is awarded to J. P. Alberger, of Phildelphia, for specimen No. 144, a russet trunk, well finished, and substantial. Hats. A certificate of honourable mention is awarded to C. F. Raymond, of Philadelphia, for his specimen of four dollar hats, the quality of which was very superior, and would have entitled him to the premium, had he exhibited the requisite quantity. Certificates of honourable mention are awarded to Thomas Elmes & Co. and to Wilson & Laing, for their specimens of silk hats, pronounced, by the judges, the best exhibited. A certificate of honourable mention is awarded to Brown & Siddons, for the improvement manifested in the hair seal caps manufactured by them. A certificate of honourable mention is awarded to J. Chandler Smith, for the superior six dollar and nine dollar hats exhibited by him. A certificate of honourable mention is awarded to E. Kimber, Jr., for his specimens of fur bonnets. Books and Stationary. Premium No. 13, to the maker of the best white vellum quarto post papaper, made from the best No. 1 domestic rags, weighing not less than eight pounds per ream, is awarded to the Brandywine Manufacturing Company, for specimen No. 189. The other articles of stationary were numerous, and some of them very creditable to the trade, but there was nothing among them requiring a special award. Fancy Articles. The silver medal of the Institute is awarded to John Yard, Jr., of Philadelphia, for his beautiful display of pearl work, in the manufacture of which he has attained great perfection. The silver medal of the Institute is awarded to the Pennsylvania Instition for the Instruction of the Blind, for the general assortment of their manufactures, an inspection of which affords pleasing evidence that the individuals who compose this unfortunate class are capable of becoming useful members of society. A certificate of honorary mention is awarded to Reuben S. Gilbert, of Philadelphia, for specimens of engraving on wood, evincing very great improvement in this art. A certificate of honourable mention is awarded to the pupils of the northwestern public school, for specimens of lace work, of superior quality. Paper Hangings. A certificate of honourable mention is awarded to Charles Longstreth, of Philadelphia, for his varied and beautiful display of paper hangings, which do much credit to his skill and good taste. The brevity required in this report necessarily excludes a great variety of interesting articles, which deserve commendation; but as the committee intend availing themselves, as far as practicable, of the reports of the judges, for future publication, the merits of these will be more fully and satisfactorily discussed. The committee cannot close their labours without expressing their obligations to the gentlemen who composed the committees of arrangement, and of judges, for their exertions in forwarding the views of the Institute, and promoting the great cause in which it is engaged. All which is respectfully submitted. SAMUEL V. MERRICK, JOSHUA G. HARKER, ALEXANDER FERGUSON, JOHN C. CRESson, Committee on Premiums and Exhibitions. Mechanics' Register. AMERICAN PATENTS. LIST OF AMERICAN PATENTS WHICH ISSUED IN OCTOBER, 1835. 1. For an improvement in the Double Speeder; William Field, North Providence, Providence county, Rhode Island, October 6. This improvement "consists in a plan of compressing the roving on the spool so hard, or compact, that the same quantity may be put on a spool of only one-fifth of the common size. A machine with this improvement will Occupy only one-half of the room, will require much less power, and will run at least one-third faster than common speeders." The usual plans for drawing, twisting, and winding, the roving, are followed; but the spools are run faster than the flyers, to take up the roving, instead of permitting them to fall back, in the common manner. The flyers are supported wholly above and independent of the spindles, are about one-half the usual length and diameter, and have a hoop at their lower ends to prevent their expanding. The condensation of the roving is effected by the pressure of a thin, circular, plate against it, as it is wound on the spool; the plate being about the same diameter as the spool. VOL. XVII. No. 5.-MAY, 1836. S1 The claims are to "the plan of compressing roving on spools by circular plates, having a rotary motion, acquired by their pressure on the spools, the edges of which act on the roving as it is received from the flyers, and thereby condense it, so that a much greater quantity can be deposited on spools of the same size. The sliding rail in the rear of the spools, on which the circular plates are placed, and the connection between the increasing size of the spools, and the traverse motion of the belt guide, so that the spools may cause the variation of speed which their constantly increasing size requires. The application of a heart motion for traversing the spools, so formed as to cause them to rise with greater velocity than they fall, so that a less quantity of roving may be deposited on the spools when rising than when falling." 2. For an improvement in Lamps; Samuel Rust, city of New York, October 6. The improvement here described is to be applied to lamps with flat wicks, and consists of a notched roller for raising the wick, the roller crossing it near its upper end, and being turned by the finger and thumb. We are much mistaken if such a contrivance has not been previously in use, for the same purpose. 3. For Glazing or Preparing Pelisse Wadding; Stukely Turner, Cranston, Providence county, Rhode Island. First patented July 25th, 1833; patent surrendered, and reissued upon an amended specification, October 6. At p. 37, vol. xiii., we gave a sufficiently full account of this apparatus, and remarked that it did not contain any claim; the surrender and reissue thereof is intended to cure this defect, the following claims being now made. "Of the above described apparatus, I claim as my invention the improvement of taking the cotton from the carding machines, and carrying it on an apron, or aprons, to the first glazing roller. I also claim the placing at the other end of the machine, a second glazing roller, with two upper rollers, all constructed like the first, to glaze the other side of the sheet of cotton. I also claim the placing two pressing rollers, instead of one, over each glazing roller. I also claim the carrying the cotton to the second glazing roller by an apron, after it has passed over the first glazing roller, and of carrying the cotton after it has passed over both glazing rollers, and been glazed on both sides, on an apron, until it is sufficiently dried, and the rolling it on a beam, which is revolved by the friction of the last mentioned apron." 4. For a Planing Machine; Reid R. Throckmorton, city of New York, October 6. as, This machine differs from those which have preceded it to such an extent in our opinion, to merit the character of novelty; that of utility it must acquire, if at all, by its actual performance. The general arrangement of the apparatus only, is shown by the specification and drawing; but, if constructed from these, most of the details would have to be invented by the builder, as the information given is very defective in this respect. The plane is to be about three feet long, and its face is to be a segment of a circle, of about eight feet in diameter, and there are to be seven, or more, plane irons, or cutters, extending from it, of such width as may be necessary. To the upper part of the plane, a rod, or shackle bar, is attached, the other end of which is moved by a crank, thus causing the plane to traverse, or rather to vibrate, backward and forward, with a rocking, or curved, motion. How the cutters are to be kept upon the plank, and caused to cut to a proper depth, does not appear, as, in the drawing, they are represented as standing out like knives, far below the face of the plane. Tongueing and grooving is to be effected in a similar way, by cutters operating laterally, and moved by a crank. The claim is to "the peculiar construction of the plane, and the nature of its motion, being vibratory and rectilineal," &c. There must be more in this machine than is described in the specification, or than meets the eye in the drawing, or it will be found of little value. 5. For Fire-places and Furnaces; Ebenezer S. Greely, Dover, Penobscot county, Maine, October 6. The patentee calls this an air fireplace, and says that the improvement is founded on its construction, and conveying heat from one room to another, without any risk of fire, &c. The whole affair consists in having the top, hearth, back, and jambs, of the fireplace, hollow, conducting air into them from without, and distributing it, when heated, by means of pipes. There is not any claim made to this mode of constructing fireplaces, and we presume that there are but very few of our readers who are not aware that, so far as our description goes, there is nothing to claim; the same may be said of the whole, as specified. 6. For a machine for Thrashing and Cleaning Clover, or Rice; Moses Davenport, Phillips, Somerset county, Maine, October 6. The machine here described consists of a long trough, containing the feeding, rubbing, and other apparatus. It is too complex for verbal description, but its characteristic feature appears to be, the passing of the seed between rubbing boards, covered with perforated metal, or otherwise made rough, the lower board being stationary, and the upper one, as it vibrates, bearing on the seed in one direction only, it being raised in the return stroke. 7. For an improvement in the mode of Rearing Silk Worms; Gamaliel Gay, Poughkeepsie, Dutchess county, New York, October 6. (See specification.) 8. For an improvement in the Saw Mill; Uri Emmons, city of New York, October 6. The proposed improvement consists in hanging the saw, without employing a saw frame, and in using springs to counteract the weight of the saw, the pitman, and other appendages. The spring it is proposed to make of wood, and to fix it like that of a pole lathe. The saw is to have a jointed lever extended back from it, both at top and at bottom; these, when the saw is down, will be at right angles to it, and as they rise in a segment of a circle, will draw the saw back, so as to allow the feeding of the log. Both above and below the log, the saw is to pass between cheeks, or guide pieces, to keep it steady. The claim is to the construction and application of the first described spring to the common saw gate; and also the construction of the second described apparatus in every respect, as they may differ from any thing else before used or known," &c. The law requires that the patentee should distinguish his invention from all other things before used, or known; but, in the case before us, this task is put upon the public, a task from which they ought to be relieved, as it would impose upon them the ungrateful necessity of informing the patentee that saw gates have been sustained by reacting springs; that saws have been hung without frames, by vibrating levers; that guides, such as he has described, have often been used, and that they, therefore, are unable to discover any thing novel in his invention. 9. For a Chaffing Thrashing Machine; Russel Bradley, Williston, Chittenden county, Vermont, October 6. We cannot afford more lines to this apparatus than there are pages in the specification of it. The unthrashed straw is to be laid lengthwise in a feeding trough, where it comes into contact with a revolving cylinder, carrying circular saws, at short distances apart, serving to cut the whole into chaff; it then descends to a thrashing cylinder, and thence passes through a winnowing machine of the ordinary construction. The claim is to the application of the circular saws. 10. For a Spring Saddle; Joel Woodward, Marshalton, Chester county, Pennsylvania, October 6. The spring part of this saddle is confessedly similar to such as are already in use, consisting of a flat side, having a spring wound spirally round it; the claim to improvement is merely in the mode of putting the parts together by screws, so that they may be easily separated. The kind of spring used was made the subject of a patent about a year or two ago; the present patentee cannot, therefore, adopt it as his own, merely because he has put it together in what he deems a more convenient way. If the patent alluded to was for a plan previously known, and belonging to the public, he may certainly sustain what is new in his own mode. 11. For a machine for Shaving Staves, Heading, and Shingles; John Everhart, Jacob Pearson, John Morford, and Nathan Everhart, Warren county, Ohio, October 6. The specification of this instrument is laboured, but obscure; the drawing is very well executed, but does not exhibit the parts in detail sufficiently to make up for the defects in the description; the general construction of the apparatus, however, may be collected from the two; but we shall not dwell upon it, as it does not present any thing which, in our opinion, bespeaks it equal to several other machines for the same purpose, although it is the joint production of no fewer than four inventors. The articles to be shaved are laid upon a solid bench, and are forced to pass under fixed knives, by a lever, which is drawn against them by a badly constructed endless chain of iron, producing more than double the friction that is necessary. The claim is limited to this endless chain, and the cogged shaft by which it is to be drawn forward. 12. For Distilling Alcohol from Apples; Anson Walcott, Bloomfield, Ontario county, New York, October 6. The pommage is to be put into a steam-tight tub, into which steam is to |
