26. For improvements in the machine for Planting Seeds; Joseph Jones, Newton, Gloucester county, New Jersey, October 11. We have here alleged improvements on that kind of planting machines in which the seeds are carried into the dropping tube from the hopper by means of a slide; and the first improvement consists in placing the rest board, on which the slide works, directly under the aperture in the hopper, so as to leave a passage into the dropping tube on each side of the rest-board, that seed may be discharged on either side at each back and forward movement of the dropping slide. The covering roller has its bearings in two arms jointed to the frame, and to two segments provided with a set screw, by means of which the depth of the machine may be regulated.

Claim. "What I claim, is, first, the method of combining the rest board with the spout and slide, by arranging the rest board over the centre of the spout under the slide, so as to leave a passage at either side of the board for admitting the seed into the spout on both the forward and backward motion of the slide; and in combination with said arrangement the method of adjusting the rest board by means of screws; second, the combination of the arms, segments, and screws, for adjusting the height of the roller for causing the plough to enter more, or less, as well as for rolling, as described."

27. For an improvement in the Hydraulic and Pneumatic Cock; John Lee Chapman, Baltimore, Maryland, October 11.

There is a cylindrical hole in the head of the cock, extending from, and at right angles to, the aperture, for the passage of the fluid, in which slides a cylindrical plug, having the lower end made conical, to fit into a conical recess in the body of the cock, and intercepting the aperture for the passage of the liquid. The conical and cylindrical parts of this plug are covered with leather packing, and the upper end is squared to fit and slide in the cap, which is screwed on to the head with leather packing interposed; and this cap has another cap screwed on to it, for the purpose of retaining the key, by a flanch on the body of it, which is tapped into the upper end of the plug, for the purpose of working it up, or down, to open, or close, the aperture.

Claim. "I claim the manner of forming the plug, and the chamber within which it operates; the lower part of said plug being made conical, and adapted to the closing of the passage of fluids through the cocks; and the upper portion thereof being cylindrical, and so packed as to be rendered air and water-tight, substantially in the manner and for the purpose herein described. And I do hereby declare that although I have represented and described the particular manner in which I put the respective parts of the instrument together, and which I consider to be the best arrangement thereof, I do not intend to limit, or confine, myself to this precise mode, but to vary the same as I may think proper, whilst the part upon which the severe action of the cock is dependent, are combined and operate substantially as set forth."

28. For improvements in Self-Acting Mules, Billeys, Jennies, Jack Frames, &c.; Richard Roberts, Manchester, England, October 11. We are under the necessity of omitting a descriptive notice of this invention on account of its complexity, as the attempt to give any idea of its character, in the narrow limits of a sketch, would be vain. This omission is the less to be regretted, from the circumstance that the description and drawings will be found at large in the Kepertory of Patent Inventions; but we insert the claim for the benefit of those who are acquainted with the mechanism, and who may desire to be informed of the limits of the letters patent granted in the United States.

Claim. "Having described my improved mechanism for adapting the rotation of the spindles to the regular taking up of the yarn as the form and diameter of the cop changes, throughout the operation of winding on; I do hereby declare that my invention consists in the method, or means, to be employed for that purpose herein before described. The mechanism thus employed by me effects the rotation of the spindles in two ways; first, rotary motion is given to a drum, or barrel, which turns the spindles, whilst the carriage is running in, by uncoiling from it a portion of a cord, strap, or chain, attached to the drum, and having its other extremity fastened at some point in a radial arm which describes an arc, whilst the winding on drum is receding from the point of attachment of the cord in a right line. This compound motion adjusts the rotation of the spindles to the varying power of taking up by the conical cop, as the yarn, or roving, is being coiled on its different diameters during the winding on of each stretch. Secondly, during the progress of the formation of a cop the situation of the point of attachment of the uncoiled end of the cord, strap, or chain, on the radial arm, is changed progressively, as the increasing bulk of the cop demands fewer revolutions of the spindles to take up the stretch, and, consequently, there is a shorter length of the cord to be uncoiled from the barrel. And I declare that the form and proportions of the different parts of my improved mule, as well as the materials of which the same may be composed, may be varied. according to the discretion of the workman employed in constructing the same, without departing from the object and principle of my improvements."

29. For an improvement in the Boiler, or Caldron; Lansing E. Hopkins, New York City, October 11.

The fire place, or furnace, is surrounded by a boiler, except where the door for the fuel is placed, and the smoke pipe, or chimney, passes out through the top of the boiler, and the caldron is let in the top of the boiler, so that its bottom and sides are exposed to the direct action of the vapor in the upper part of the boiler.

Claim. "What I claim is the particular manner of arranging and combining the furnace, the steam boiler, or generator, and the caldron; the general form and arrangement of these parts being substantially the same with those described; without, however, intending, by the

accompanying description and representation, to limit myself to any precise shape, or proportions, of the respective parts, but to vary these as I may find convenient."

30. For Pneumatic Springs applied to Railroad Cars; Levi Bissell, Newark, Essex county, New Jersey, October 11.

Claim "What I claim as my invention, and desire to secure by letters patent, is the application of compressed air, or other permanently elastic fluid, in a cylindrical, or other shaped, vessel, made of metal, or other hard substance, and acting against a piston working therein, for the purpose of springs for railroad cars, or other carriages

It may be well to say, that at the time application was made for letters patent for this supposed invention, the applicant was informed that it was known to the officers of the department, that this device had been applied to carriages, and used for various other purposes, as a substitute for metal springs; but that after a diligent search in the records of the office, and the library, which, unfortunately, is too limited, no evidence could be found, such as the law requires the commissioner to furnish, on refusing to grant letters patent, and that, therefore, it was optional with him to demand one, or withdraw his application; that he might, however, rest assured that if he did obtain a patent he would not be able to sustain it. He did insist on the grant, and some time afterwards he was furnished with the evidence of the want of novelty.

31. For an improvement in the Elevated Oven for Cooking Stoves; Rensselaer D. Granger, Albany, New York, October 11.

Claim "What I claim is the manner in which I have constructed the elevated oven by extending flat flues at either end by means of end plates, arranged and operating substantially as set forth; the heated air from the fire chamber entering the lower flue, and escaping from the upper, in the manner described."

32. For a mode of rendering the Pockets of Garments Safe against Pickpockets; Daniel Harrington, Philadelphia, Pennsylvania, October 11.

The surface of the pocket is covered with fine metallic chain, or with metallic, or other buttons, or quilted with metallic wire. And to prevent a pocket, &c., from being cut away, one, or more, strands of chain are carried from the pockets to some other part of the dress. These are described as applicable to reticule bags, and other similar bags.

Claim. "What I claim as my invention, is combining pockets constructed substantially as described, with the various articles of wearing apparel set forth."

33. For improvements in the Cooking Range; N. P. Kingsley, Boston, Massachusetts, October 11.

37. For an improved mode of preventing Cotton, or Wool, from falling to waste from the Carding Machine; Joseph Munroe, Palmer, Hampden county, Massachusetts, October 11.

The patentee says, "The nature of my invention consists in providing the under side of the carding machine with a screen, or sieve, in such a manner that the dirt, which the cotton, or wool, contains, may fall through the screen, while the cotton, or wool, is kept in contact with the cylinder of the carding machine by means of the screen, and not permitted to fall down under the machine, and go to waste.'

Claim. "What I claim as my invention, is the application to carding machines of a screen which will permit the dirt, motes, &c., to escape, without the cotton, or wool, as described."

38. For an improvement in the Jaws of Bench Vices; William Sim, Schenectady, New York, October 11.

This is for making cast-iron bench vices with steel jaws, or facing the jaws with steel, by casting the body of the vice on to the steel plates, which form the facings of the jaws.

Claim. "I claim the manner in which the steel face, or lip, of the jaws, as described, is formed and constructed, and the manner of joining the lip thus constructed of steel to the jaws, by casting the lip of steel separately with three, or more, holes, and then placing the steel lip in the mould where the jaw is to be formed, and in this manner uniting the lip of steel to the iron jaw, thus forming the jaws of distinct metals, and in a simple and durable manner, as described.”

39. For an improvement in Railroad Cars for Running on Curves ; Perry G. Gardiner, assignee of Isaac Bullock, New York City, October 11.

This improvement is for the purpose of throwing the axles of the wheels in the radii when the car passes over a curve; each wheel is on a separate axle, that has its bearings in a frame extending from the outside to within a short distance of the middle of the truck frame. The outer ends of the wheel frames are jointed to the truck, and the inner end of the right hand back frame is connected by a joint rod with the inner end of the left hand forward frame, and the other two in the same manner, and the inner end of the two back frames are connected with the two T arms of a T lever; the third arm of which is for the front car, attached to the axle of two leading, or guide, wheels, and for the other cars, to the back of the preceding car, and for the back truck of double truck cars, to the back of the front truck. From this arrangement, it is evident that the moment the (7) lever is, by the leader, or preceding car, thrown in the direction of the radii, the axles of the wheels must, of necessity, follow."

Claim. "I do hereby declare, that I do not claim the mere cutting of the axle into two parts, so as to run independently of each other, nor do I claim running each wheel in a separate vibrating frame connected with the frames of the other wheels, by means of connecting

rods, these having been done, but without the farther connexion hereafter claimed; but what I do claim as constituting my invention, and desire to secure by letters patent, is so connecting the sliding boxes, (for the frames in which the wheels revolve,) by means of connecting rods with a lever in the form of a cross, or letter T, (which connects the car with the next preceding car, or in case two, or more, trucks carry one frame, may connect the said trucks with the said frame,) as to adjust all the wheels simultaneously, and enable them to receive the adjustment from the preceding car, or frame, or from the frame of the car itself when two, or more, trucks carry one frame, all substantially, as described."

40. For an improvement in the Valves and Pistons of Pumps; John Clark, Portsmouth, Norfolk county, Virginia, October 11.

The nature of this improvement is distinctly pointed out in the following

Claim. "What I claim as new, is the attaching of the pistons and valves, the former to the piston rod, and the latter to a rod, or bar, of metal, by a joint pin out of their centres, by which they will be enabled to tilt, and allow the passage of water upwards, and will resume their horizontal position when the water, or other liquid, is not ascending within the pump; the said valve being made so as to occupy the whole section of the barrel of the pump, and the arrangement and operation of the respective parts being substantially such as are described and made known."

41. For an improvement in the Steam Boiler for culinary purposes, &c.; Solomon C. Riley, New York City, October 11.

The fire is contained in a cylinder, or pot, which is surrounded by another cylinder, leaving a space between the two for water, which constitutes the boiler. The space uniting the two cylinders at top may be provided with cooking holes, and a steam pipe, and the top of the fire cylinder may be adapted to receive either a caldron, or a plate, with several boiler holes.

Claim. "I do not claim the discovery of a double cylinder, or the use of the caldron; but what I do claim as new, is first, the combination of the double cylinder, boiler, and caldron with the space between the double cylinder left open at top. Second, the same with a cap pierced with kettle holes, for the purposes described."

42. For an improvement in Traveling Trunks; John Fitzgibbons, Philadelphia, Pennsylvania, October 11.

Claim. "What I claim as new, is the constructing of trunks, and other articles of similar character, with their front and back sides rendered alike in appearance, by covering the key holes with screwed knobs, resembling the rows of knobs used to ornament and strengthen such articles, and by making the strip which forms the cover of the opening between the lid and the lower part of the trunk of hoop iron, or other rigid substance, covered with leather, or other suitable ma
