the adjustable files, and the apparatus for lifting them, in order to liberate the saw teeth from their action, as the saw is shifted.

10. For an improvement in the mode of preparing, applying, and using certain fluxes for the Reduction of Ores in the Blast Furnace; Jonas Towers, Madison, Lake county, Ohio, December 7. Claim. "What I claim as my invention, and desire to secure by letters patent, is the application of those earths or minerals which are dissoluble or diffusible with water, and have an adhesive nature, and can be made into a paste, pap, or grout, with the above or other liquids, and can be applied as other fluxes for the reduction of ores or minerals in the blast or other furnaces. I claim the application of the above preparation, as herein described, to other minerals as well as iron, which have a similar objectional tendency, while smelting, that is found with iron. I do not claim any special right to the use of the above fluxes in a dry or natural state; it is only after they have been mixed or diffused with water or other liquids, and formed into a paste, pap, or grout, and applied as a coating or adhering substance, as herein described, that I claim as my invention, or discovery, and desire to secure by letters patent."

11. For an improvement in the manufacture of Cassimere Hats; John Maguire, Washington, D. C., December 7.

Claim." What I claim as my invention, and desire to secure by letters patent, is the making of hats of two distinct and seamless parts, viz: the body and the cover-the whole being manufactured in the manner and for the purpose herein above set forth."

12. For an improvement in the Machine for Cleaning Grain; Thos. A. Chandler, Rockford, Ill., and Asa D. Reed, Niles, Mich., December 7.

Claim." What we claim as our invention, and desire to secure by letters patent, is the manner herein set forth of separating the grain from the straw and chaff by means of a screen constructed with parallel elastic wires fixed at one end, and free to move at their other ends, merely resting upon the frame of the screen-said screen vibrating up and down, by which means the elastic movement of the wires opens the straw, and thus gives full action to the blast."

13. For an improvement in the Furnaces of Steam Boilers, &c.; Leman Bradley, Sharon, Litchfield county, Ct., December 12.

This consists in dividing the stack into two, three, or more compartments, by means of partitions extending from the top to a point a little above the entrance of the blast. Into one of these divisions the coal only is put, and the usual charge of ore, coal, &c., in the others; and that part of the hearth which is below the coal division is elevated above the other portion, that the coal may be kept up to the blast,

and permit the melted metal to descend below it. The patentee sums up the operations and the advantages in the following words, viz: "The greatest part of the charge being put in the compartment next to the head-stone, the metal will rest on the boshes, and will not come down faster than it is melted by the blast-the principal part of which comes in through the body of coal in the chamber, from the blow-pipe; the combustion being thereby rendered perfect before the blast reaches the metal, a great saving of fuel is effected, and a better quality of iron is produced. The damper over the coal chamber is kept down during the operation, and the gases are allowed to escape through the chambers on the opposite side of the partition. The fuel in the chamber rests on the hearth, and cannot fall much below the blast. A small blast can also be thrown in on the opposite side of the furnace to the main blast, which is regulated at pleasure."

Claim. "Having thus fully described my invention, what I claim therein as new, and desire to secure by letters patent, is forcing the air into the fire-chamber in the manner described, above and below the fire, in combination with the method of discharging the products of combustion, as herein set forth, from the fire-chamber. I also claim, in combination with the above, the forcing the products of combustion through a reservoir of water, substantially in the manner and for the purpose above set forth."

14. For an improvement in the Apparatus for regulating the Draught of Chimnies; Joseph Hurd, Stoneham, Middlesex county, Mass., December 12.

The patentee says: "My apparatus, although similar in its principle to the Barker's Reaction Mill,' and operating very much like it, is nevertheless applied to the top of a chimney for a different purpose from what the said mill is generally applied-the object of such apparatus being to keep up a steady and regular draught through the chimney, and at the same time prevent the wind from blowing the smoke down the flue."

Claim."I shall claim the employment upon a chimney, or discharge flue, in the manner described, of a long tube, having closed ends, and orifices through its opposite sides, at or near its ends, and otherwise arranged and operating as set forth, the same being for the purpose of regulating the draught and facilitating the escape of smoke, as explained."

15. For an improvement in the Centrifugal Reaction Water Wheel; Samuel L. Valentine, Bangor, Penobscot county, Me., Dec. 12. Claim. What I claim as my invention, and desire to secure by letters patent, is the water-wheel constructed as herein described, the buckets of which are on a line exactly parallel with the shaft in their cross section, and extend into the centre with flat rings around their periphery, and without any shrouding beyoud the outer rings towards the centre-the whole being arranged so that the wheel can be made to run either way, in the manner and for the purposes herein set

forth, combined with the flume on each side thereof, as herein specified."

The reader may imagine this to be a reaction water wheel of the usual construction, with the buckets extended to the shaft, and without a plate on either side of the buckets, so that the water can be applied on both sides, the shaft being horizontal, and the flume so arranged as to conduct the water to both sides. The wheel is provided with rinis at the outer extremity of the buckets.

16. For an improvement in the Abdominal Supporter; Calvin Cutler, Springfield, Hampden county, Mass., December 16.

Claim. Having thus explained the nature and principles of my invention, it is not my intention to claim generally the use of lateral pads, as heretofore applied, but to claim one or more lateral pads as combined with or used in connexion with the central pad, and in front of the crest of the ilium, for the purpose of producing uniform pressure on the site of the colon and kidneys on the right side, from the capal coli, or head of the colon, to the lower rib of the same side. and upon the left side from the sigmoid flexure of the colon to the power rib of the same side.'

17. For improvements in Machinery for Cutting Leather into Soles for Shoes and Boots; Richard Richards, Lynn, Essex county, Mass., December 16.

The claims in this case refer to, and are wholly dependent on, the drawings, the publication of which, from the numerous sections, would carry us beyond the limits of this work, and therefore we are under the necessity of omitting the claims.

18. For an improvement in Saw Mills; Calvin Stigleman and Austin Seely, Madison county, Ill., December 16.

This saw is to be worked without the usual saw-gate for straining it, this being effected by the elastic force of steam. The two ends of the saw are connected each with a steam piston, the lower one being much larger than the upper one, and the two cylinders in which they work are connected together by a steam pipe, so that the pressure of steam acting on the two pistons strains the saw, and it is carried down to cut by reason of the greater capacity of the lower piston than the upper one.

Claim. "What we claim as our invention, and desire letters patent for, is the adaptation and application of the upper cylinder in straining and running of saws without a frame, and for all other purposes for which it can be used to advantage, as represented in the drawing herewith transmitted."

19. For an improvement in Splints for Fractured Limbs; Lewis Post, Lodi, Seneca county, N. Y., December 16.

Instead of the splint box, or double inclined plane, hinged and provided with screws, as heretofore employed, the present patent is for making of the splints themselves, which are adapted to the form of the limb, the double inclined plane, by uniting with a hinge the extension, thigh, and leg splints.

20. For an improvement in the Cooking Stove; Archibald Whiting, Middletown, Dauphin county, Pa., December 16.

We are under the necessity of omitting the claim in this case also, as it refers to, and is wholly dependent on, the drawings. It is limited to an arrangement of the flues and dampers for conducting the draught around the oven back of the fire chambers, and the one which extends under the fire chamber and the back oven.

21. For an improvement in the Cooking Stove; Wm. L. Potter, Clifton Park, Saratoga county, N. Y., December 19.

Claim. "What I claim as my invention is the mode of combining my two ovens and flues, viz: the draught descending at the back of both ovens, under the lower oven, and up in front of the lower oven in one entire sheet, and dividing at the front of the upper part of the lower oven, on either side of the stove, into two flues, the draught under the upper oven being directly from the lower part of the fire chamber through a contracted flue, in the manner and for the purpose described."

22. For a Machine for making Wooden Boxes for Match Splints, &c.; John H. Stevens, New York city, N. Y., December 19.

These boxes are made by cutting out a square groove from a block of wood, by means of two circular saws on one shaft, placed at a distance apart equal to the width of the inside of the intended box, and the wood between them is cut away by rotating cutters, and then by two small circular saws, at right angles to the first; small grooves are cut near the upper edges to receive the cover. The ends are glued in afterwards.

Claim. What I claim as my invention, and desire to secure by letters patent, is the combination of the cutter and saws, by which the boxes are cut out with the cutters, for making the grooves to receive the lid as described.”

23. For a Machine for Planing and Dressing the knuckles of Butt Hinges; Gage Stickney, Blackwoodtown, Camden county, N. J., December 19.

The hinge, opened, is placed on the bed of the machine, with the projection of the knuckle which is to be planed, upwards. Two guide jaws are brought down upon it, one on each side of the knuckle, and kept down by weights, and the hinge is then forced forward against the tool which planes and dresses the knuckle to the form re

quired there being guide pieces beyond the cutter, to guide the hinge as it passes under the cutter.

66

Claim. Having thus fully described the nature of my improvements in the machine for planing or dressing the knuckles of butt hinges, and shown the operation of the same, I do hereby declare that I do not claim to be the inventor of either of the individual parts or devices herein described, when taken separately and alone; but what I do claim as constituting my invention, and desire to secure by letters patent, is the particular manner in which I have combined and arranged these parts so as to adapt them to the operation of planing or dressing, as set forth: that is to say, I claim the manner of forming and arranging the guide jaws, so as to press simultaneously on each side of the hinge to be planed, in combination with the follower, the bed, the planing tool, and the guide-pieces which govern the hinge as it is being planed-the whole combination and arrangement being substantially the same with that herein set forth."

24. For an improvement in the Plough; Anthony Taylor, Greenford, Columbiana county, Ohio, December 19.

The point of the plough is covered by an additional point, made with a socket, to slip on to the usual point. And for the purpose of strengthening the land side, an additional land-bar is put on by bolts, the forward edge being made with a lip and sharp edge, to embrace

the share.

Claim. -"What I claim as my invention, and which I desire to secure by letters patent, is the use of the shoe or socket point, made as aforesaid, in combination with the before-described plough. I do not claim an additional or false land bar, but the mode, herein described, of strengthening the share by means of the extra land bar, by which I am enabled in my plough to use wrought-iron shares."

25. For an improvement in Safety Switches for Railroads; Gustavus A. Nicolls, Reading, Berks county, Pa., December 19.

Claim."What I claim as my invention, and desire to secure by letters patent, is a safety turnout switch, embodying the combined use of inclined planes and guides to elevate and slide the wheels on the tracks, and the combination of these planes and guides with the safety bars."

This improvement, as indicated in the above claim, consists in the employment of two parallel bars attached to, and moving with, the switch; so that, when the switch has been shifted and put in connexion with the turn-out rails, they are in line with the rails of the main track; and, in the event of neglect on the part of the attendant to replace the switch, a car from the main track will run on to these parallel bars, which are, at their fixed end, connected with the main track by means of inclined planes and guides, so arranged as to elevate the flanch of the wheels (which are outside the track) over the rail, and guide the whole of them to the line of the track, and thus prevent the cars from running off.
