"I do not claim the making of what is termed the pantaloon button in two pieces of metallic plate, held together by the edge of one being turned over upon that of the other, nor do I claim the combination of two plates (so applied to each other,) with a circular or other proper shaped piece of wood, or cloth, or woven material interposed between them; neither do I claim the combination of a plate of metal and a circular disk of wood together, the former being confined to the latter by its edges being lapped over and pressed down VOL. X, 3RD SERIES.-No. 5.-NOVEMBER, 1845.

27

upon those of the latter: but what I do claim, is my improvement in the modes usually adopted for forming or making the eyelet holes or thread passages of buttons composed of two circular plates of metal, the one of said pieces being confined to the other as above described; the said improvement consisting in punching holes through the plates, (so as to leave a bur projecting on one side of the plate from each hole) before they are applied and connected to each other, and (it combination with) applying the said holes of one plate to those of the other, in such manner that their burred projecting edges may be in direct contact, and the countersunk portion of each of the holes of the plate (there being the same number of holes in each plate) be oppo site to that of the corresponding hole of the other plate, thereby form ing eyelets or passages countersunk on both sides of the button; by which mode of constructing the above, wear of the threads which se cure the button when sewed to cloth or other material, is to a very great degree obviated-the whole being substantially as above described."

15. For an improvement in the tool called the Shoemaker's Shoulder Iron, for setting and polishing the edge or forepart of the Soles; James W. Newberry, Kensington, Philadelphia county, Pennsylvania, February 12.

In the instruments or tools now used for this purpose, the bevel edge, which is used to polish the edge of the sole, is permanently connected with the shoulder which determines the thickness of the sole, and therefore one instrument is required for each thickness. This patent is granted for connecting the bevel edge with the shoulder by a slide regulated by a screw, so as to adapt one instrument to any thickness of soles. The claim is limited to the combination of the bevel edge and shoulder, in the manner described, the distance be tween the two being regulated by a screw or other analogous device.

16. For improvements in Printing Presses; J. C. Kneeland, Troy, Rensselaer county, New York, February 20.

The patentee says "In my press as represented in the drawings accompanying the specification, I place the form vertically; but it may, if preferred, be placed horizontally, by arranging the toggle joint and the other parts concerned in giving the impression in such manner as to operate in that position, my improvement not relating to that part of the apparatus by which the platen, the frisket, the inking apparatus and their immediate appendages are operated, or in which they are arranged, these being similar to such as are well known, but consisting, principally, in a novel arrangement of the apparatus for griping the sheet which is placed on the feeding board; and for carrying it into the proper position for, and holding it whilst it is, re ceiving the impression.'

We are under the necessity of omitting the claim, as it refers to, and is wholly dependent on, the drawings; but the foregoing extract from the specification fully indicates the nature of the improvement patented.
