We do not think that its new arrangements are so characteristic as to "distinguish it from all other things before known or used," without some specific pointing out of its novelties.

61. For a Cooking Stove; Le Grand Fairman, Medina, Orleans County, New York, June 26.

There is not any thing special in this stove, entitling it to particular notice. It is to have two ovens, one on each side, and any required number of openings in the top plate to receive cooking utensils, or dampers to direct and regulate the heat.

62. For Portable Ovens, or Cooking Stoves; Charles Vale, Newark, Essex county, New Jersey, June 26.

There appears to be but little novelty about this stove, excepting in the name given to it at the end of the claim, which is as follows: "The parts I claim as my invention, and not known, in the above portable ovens, are the particular construction of the fireplace, which only allows one-third of the fuel it will contain to be ignited at one time, and cause that to be regular as long as there is that quantity in it. The double shelves, and the manner of conducting the smoke and heat over the whole surface of them, by which so much fuel is saved, and from which I call it the Chaloric Extractor."

63. For a Machine for Cutting Straw; James M.Math, Meadtown, Crawford county, Pennsylvania, June 26.

"What I claim as my invention, and not previously known in the above described machine is the so affixing the knives to the gate, or slide, that they will follow each other at a distance just sufficient to allow the first to have passed through, or nearly through, the material to be cut, before this second comes in contact with it, and so on according to the number of knives used; and by giving a degree of length to the gate, or slide, and also of length to the lever, by one stroke of the lever the whole number of knives shall each in succession have passed through the straw."

It is calculated that by such a machine, four times the work may be performed, "with little, if any, additional power."

64. For a machine for Felling Trees; James Hamilton, city of New York, June 26.

The patentee, after describing the construction of his machine, says, "this applicant in the next place describes the principle of his invention, as follows. It consists of the combination of a horizontal saw with a crank movement, the saw being of any convenient length, but in the shape of a small segment of a circle, and the length of the crank with which it is directly connected being sufficient for the length of the intended stroke of the saw, the saw being fixed in a frame, and this moving in a centre fixed in another movable frame which is connected with and movable upon the same centre as that of the crank; this frame having a horizontal circular movement upon a roller, by force of a weight acting over a pulley, so as to bear the saw forcibly against the material to be sawed, the crank being made to act by any convenient mechanical motion, the whole operating so as to saw horizontally, it being designed for felling trees by sawing through the trunk of a tree horizontally, and near the ground.'

Mechanical saws of this description have their uses, as for cutting off piles under water, &c., but they will never enter into competition with the axe of

the American woodman; and we are well convinced that in an attempt to use them in this way, his aid would not unfrequently be required to extricate the saw from the kerf in which it would become pinched.

65. For a Corn Shelling machine; John C. Dunbar, Temple, Kennebec county, and Addison Powers, Carthage, Oxford county, Maine, June 26.

This is the most old fashioned, because it is the first fashion, of shelling machines, but the patentees propose to make the concave of three separate pieces of sheet-iron, and to perforate them like a grate.

66. For a Cooking Stove; Thomas D. Burrell, Geneva, Ontario county, New York, June 26.

In the description of this Cooking Stove there are several things mentioned which are omitted in the drawing; such, for example, as openings for kettles, doors, &c. &c. The lower part of the stove, which is to contain the fuel, is represented in the form of a very low Franklin. The two upper plates of this, making part of the flues, extend far back, and from them two other plates run vertically to the height of two feet, forming a semicylindrical flue, eighteen inches in diameter within. The upper end of this also is double, and from it rises the smoke pipe.

A semicircular tin reflector is to be placed against this semicircular recess, and converts it into an oven, eighteen inches in diameter, and two feet in height. A vertical shaft within this, furnished with open, horizontal shelves, called a revolving reel, is to sustain the articles to be baked.

The claim is to "the oven formed by the flattened upright flue and covering; the upright revolving reel, and the combination of the door and openings in front, for the uses set forth." Which latter part, with its combination, we are left to guess at, it being entirely omitted in the drawing.

67. For a Napping Machine; Reuben Daniels, Woodstock, Windsor county, Vermont, June 26.

This machine is intended for the narrow kinds of cloth. The napping cylinder is made about nine inches and a quarter in diameter, and about three feet in length. The surface consists of twenty-six lags, or strips, allowing a space between each for needles to pass in and out. The napping cylinder is hollow, and has a cylindrical shaft through its centre, upon which is fitted the necessary apparatus for projecting or retracting the needle points. This apparatus is governed by screws at the end of the cylinders. The needles are fixed on metallic plates very near together, so as to stand like the teeth of a comb. This cylinder may be so placed as to operate like the ordinary teazling machine, but its motion must be much slower.

What is claimed "is the principle, or improvement of varying, gauging, or graduating, the projection of the needles, wires or teeth, which are designed to do the work, performed by teazles in the common teazling machine."

68. For a Rotary Steam Engine; Orson Baines, Van Buren, Onondaga county, New York, June 26.

This is another machine to blow away steam to little good purpose. A hollow gudgeon is to carry steam into a hollow revolving drum from two points on the edge of which it is to escape.

"Now what I claim as my own invention and not previously known, in

the above described machine, is the discharging of the steam on the outside of the rim of a tight enclosed circular wheel, at the greatest possible distance from the axis, or shaft, by which an increase of power is gained over any other rotary engine," &c. &c.

69. For improvements in the Loom for Figured Work; E. Meily, jr. and J. & S. Mellinger, Lebanon, Lebanon county, Pennsylvania: first patented March 1st, 1834. Reissued under an amended specification, June 26.

The description and drawing of this machine under which the first patent was issued, were altogether defective, and although it has been intended to remedy these defects by the amended specification and drawing, the latter are so constantly, and necessarily, referred to in the former, as to render them inseparable. We think the improvements valuable for the purposes to which they are applied; but all that we can now do towards giving an idea of them is to insert the claim, however inadequate this may be.

"We claim as our invention the general arrangement of the parts connected with the round and oval wheels, as herein described, for the purpose of operating upon the needle shaft in the manner and for the purposes set forth. We claim this manner of carrying out the pattern cards by means of friction rollers, and the steadying the same by means of a loose roller in the doubling thereof. We also claim the mode described of preparing the pattern cards upon a block of wood, by means of a hollow punch and clearer, operated upon by a spring."

70. For Riding Saddles; A. L. Van Horn, City of Philadelphia, June 26. (See Specification.)

71. For a Machine for Hulling Clover Seed; John Whiteman, City of Philadelphia, June 26.

The seed to be hulled is put into a hopper which narrows down so as to leave a longitudinal opening through which the feeding is affected by means of a fluted revolving roller. The hulling is effected by means of revolving, metallic disks, or wheels, five or six inches in diameter, fluted, or grooved, at each side and on the edges. These are placed upon two shafts, standing in the same horizontal plane, the disks on one shaft standing between those on the other, and just clearing each other and the shaft, so as to admit the seeds to pass without being crushed. Any number of disks, of which the size of the machine admits, may be placed on each shaft. The disks revolve towards each other, and the feeding takes place in the centre between them. A comb-shaped board on each side prevents the seed from escaping outside of the disks."

The claim is to a machine so arranged and constructed as that a new hulling machine is thereby formed.

72. For a Rotary Steam Engine; Charles Hill, Zanesville, Muskingum county, Ohio, June 26.

To understand the whole of the references made in the claim would require a drawing, and as our confidence in the Rotary Steam Engine is small, and our objections will yield to the omnipotence of success only, we wait the arrival of such a proof. This is one of the reaction engines, and the claim is to "the principle of increasing the surface of reaction, and diminishing the VOL. XVII-No. 1-JANUARY, 1836.

motion, without diminishing the power of the steam; which is effected by the enlargement of the steam pipes, (as at D, D,) and the vacuum created by the condensation of the steam, giving a less velocity to the wheel, accompanied by a corresponding increase of power. I also claim as my invention the introduction of water and air, either separately or in connexion, for the purpose of creating the vacuum, and the manner of introducing and dispos ing of the same; together with the manner of disposing of the steam so as to assist in maintaining the vacuum. I claim as my invention the application of these principles, to attain the objects herein set forth, whether the same be effected in the precise manner described, or otherwise."

73. For Ever Pointed Pencil Cases; Ellwood Mears, City of Philadelphia, June 26.

The improvement consists in the manner of forcing the lead out of the metal point, and is as follows. The slide, or band, which moves up and down the stick, is also capable of a circular motion around it. This slide, or band, has on its inner surface a screw thread, into which the nut of the pin, or wire, used in propelling the lead from the point, works. The band or slide is kept in its place, and pushes out this metallic point by means of two small screws fastened to the lead groove within the case, and rising on each end of the band. Thus by holding the case in one hand and turning the slide or band to the left, or, if preferred, by retaining the slide so as to be immovable, and turning the case to the right, the lead can easily and quickly be propelled from the metallic point.

"What I claim as my own invention, is the method of using the band, or slide in forcing the lead out of the metal point, instead of the complicated works heretofore in use."

74. For a Churn; Isaac Wood, Connelsville, Fayette county, Indiana, June 26.

There is an oval tub, through the sides of which a shaft is to pass, having a winch at one end by which it may be turned. The shaft must revolve in a water tight joint, and is to carry a number of arms or dashers, of such length as the tub will admit.

There is not any claim made, and, excepting in the shape of the tub, which does not offer any very apparent advantages, there is scarcely any difference between this churn and many others.

75. For a Mill for Grain, &c.; William S. Johnson, City of New York, June 26.

The patentee calls this an "eccentric mill," and proposes it as proper for grinding paints, dye stuffs, snuff, and most other articles required to be ground. A sufficient description of it may be found at p. 34, Vol. 10, as patented by James Bogardus, of the City of New York, the difference between that and the one now before us being, most manifestly, colorable only. We should think it certain that if the claim of Mr. Bogardus was well founded, the present is an invasion of it.

76. For a Machine for Planting Corn; Thomas D. Burrall, Geneva, Ontario County, New York, June 26.

After describing this seeding machine the patentee very truly says, "now in the above description there is perhaps no one part which is new in itself;"

and to this he adds: "But what I claim as my invention is the combination of the several parts above described, forming collectively a convenient and useful implement for furrowing, planting, covering, and rolling, at a single operation."

This sort of claim, to combination and arrangement, has become a kind of universal salvo where nothing new is to be found in the machine patented, but it will not answer; where there is real novelty in an invention, and it consists, as is most commonly the case, in combination and arrangement, it is as susceptible of being distinctly pointed out as novelty of any other sort: in the case before us, it is true, the task would have been a hard one.

77. For an improvement in Roofing Houses with Tin, Copper, and Zinc; John Bouis, Baltimore, Maryland, June 26.

This improvement is very imperfectly described; the apparatus used for bending the edges of the plates is not well represented, nor is any thing particularly pointed out as forming the foundation of a claim. All that we can collect of any peculiarity is that "the grooves or edges of the groove roofing being made in a semicircular form, instead of an angle as formerly constructed, give the metal a better chance to expand or contract without the danger of cracking, and also form a gutter to carry off the water and dirt, without obstruction." There are no instructions given for fastening the roofing; we conclude, therefore, that there is not any thing new in this.

78. For Flasks for Moulding Iron Tea-kettles; David Stewart, Danville, Columbia County, Pennsylvania, June 26. (See Specification.)

SPECIFICATIONS OF AMERICAN PATENTS.

Specification of a Patent for an improvement in Riding Saddles. Granted to A. L. VAN HORN, City of Philadelphia, June 26th, 1835.

To all whom it may concern, be it known, that I, A. L. Van Horn, of the City of Philadelphia, have invented an improvement in the manner of making Riding Saddles of all descriptions, and that the following is a full and exact description thereof.

The saddle need not in its general construction be in any way altered from that now pursued by the manufacturers of that article. The saddle tree, the irons, the mode of covering, and in fact all the parts may be the same with those now employed by different workmen, my improvements consisting solely in the substituting webbing, or girth, of the kind denominated India Rubber Webbing, for that which is usually strained upon the saddle tree, and which forms the foundation for the seat. The India Rubber Webbing is a well known article, consisting in part of that substance interwoven with the ordinary materials of webbing, and communicating to it great elasticity, and that in a degree peculiarly adapting it to the new purpose to which I have applied it. In order to derive all the advantage possible from the use of this webbing, I take care in straining it to draw it as high upon the cantle as possible, as by this means it will have sufficient play without descending so low as to come in contact with the back of the horse, or with the saddle tree.

A. L. VAN HORN.
