side by side, and one above them which extends over the two lower ones. The drawers communicate together by numerous small holes, which may be closed, or opened, by slides, having corresponding holes. The drawers are provided with tubes, for the admission of the bees, and those in the lower drawers are located at the junction of the two drawers, to give an entrance to the two drawers by the same tube, which is, however, divided by the partition between the two drawers. There are two of these tubes, one at the bottom, and the other about the middle of the height of the drawers.
Claim. "What I claim is the employment of separate, or double, slides between the drawers, one for each, constructed and arranged in the manner and for the purpose set forth. I also claim the divided tubes, in combination with the drawers, constructed and arranged substantially in the manner and for the purpose set forth."
30. For an improvement in Tanning Leather; Adam Kettering, and Augustus Vogle, Hempfield, Westmoreland county, Pennsylvania, June 24.
The vats are divided into five sections, each section being divided again into two compartments, one for holding the tan bark, and the other for the hides, the partition between the two being pierced with holes for the passage of the liquor; water is pumped on to the bark in the first vat, which, after receiving a certain degree of tannin, and acting on the leather, is pumped on to the bark in vat number two, where it receives additional strength, and so on throughout the series, the leather being also shifted from vat to vat through the series, as the process of tanning progresses.
Claim. "What we claim as our invention, and desire to secure by letters patent, is the above described process of tanning hides into leather in a quicker manner than usual, and without the aid of steam, or any chemical composition, and, in connexion therewith, the peculiar arrangement of the vats used for said purpose, also as set forth."
31. For an improvement in the Cooking Stove; Henry W. Camp, Owego, Tioga county, New York, June 24.
In this stove, as in many others before it, there are two ovens, one back, and on a level with the fire chamber, and the other below, there being a flue space between the top of this and the bottom of the upper oven and fire chamber, and a diving flue between the fire chamber and upper oven, and one back of the upper oven divided into three compartments. When it is desired to heat the upper oven only, a damper at the top of the flue between the fire chamber and oven is opened, which directs the draught down this flue under the oven, and up the middle division of the back flue to the pipe; but when the two ovens are to be heated, this damper is closed, and a damper that governs the two outside divisions of the back flue are opened, which directs the draught over the top oven, down the outside divisions of the back flue, over the top of the bottom flue, down the front flue,
under the oven, up the back flue of the bottom oven, and then to the pipe through the middle division of the back flue.
Claim. "What I claim as new is the particular arrangement of the flues and valves, as set forth. I do not claim either, or any, of these, excepting under the special arrangement and combination thereof, above made known, and by which they are rendered susceptible of the various changes described."
32. For an improvement in the Flax and Hemp Brake; Aaron F. Bruce, Marshall, Salina county, Missouri, June 24.
This is for an improvement in the common Dutch hand brake, which consists in dividing the standards and beams, to which the swords are attached, that they may have sufficient elasticity to yield and permit the swords to accommodate themselves to the varying bulks of hemp, and prevent the breaking of the fibres. In the hand brake the hand of the operator regulates the strength of the blow, and yields whenever it is required; but as this machine is to be worked by power, and the brake has a positive motion, the yielding of the swords becomes indispensable, in the judgment of the patentee.
Claim. "What I claim as new, is the manner of giving the necessary lateral play to the vibrating and stationary swords, so as to accommodate themselves to the varying bulk of the material, by attaching the swords to the divided beams, and divided standards, as described."
33. For improvements in machinery for Cutting and Dressing Stone; Jacob Jenks, Roscoe, Winnebago county, Illinois, June 24.
The patentee says, "The nature of my invention consists in a cutting tool that extends across the stone, said tool having a row of picks on its front edge, and just behind them, a broad chisel, the tool being vibrated, and by its weight and momentum, cuts the stone which passes under it on a carriage; side cutters of a similar construction are attached, and vibrate horizontally to cut the sides of the stone."
These cutters are attached to stocks that vibrate on centres, and, therefore, the picks and chisels cut by a vibrating circular motion communicated to them by appropriate machinery.
Claim. "What I claim as my invention, is the cutter-head, constructed and arranged as described, having chisels and picks attached thereto enough to extend across from one side of the stone to the other in a line, and all operating at once the whole width of the stone, in the manner and for the purpose described. I also claim, in combination therewith, the side cutters constructed and arranged as above specified."
34. For an improvement in Piano Fortes, Harps, and other String Instruments; Lovering Ricketts, Baltimore, Maryland, June 24. Instead of attaching the strings to pins, in the usual manner, they are hooked on the end of metallic springs, which project from studs
attached to the instruments. The inventor states that his object is to keep instruments in tune, by the elasticity of the spring connexion, which yields as the strings contract.
Claim. "What I claim as my invention, is the application of my metallic springs to the piano, harp, and all other musical string instruments, as an improved substitute for the common hitch pins now used, and for the purpose of keeping them in tune for a long period of time."
Patent Re-issued in the month of June, 1844.
For improvements in Boxes for the Journals of Railroad Cars, &c.; John H. Tims, Newark, Essex county, New Jersey, June 13.
This patent was granted on the 31st of October, 1839, and noticed in this Journal at page 394, vol. xxvi, to which the reader is referred; and as the re-issue was granted for amendments in the specification, it only becomes necessary, in this place, to insert the claim.
Claim. "I do not claim, as my invention, the supplying of oil to the journals of axles, by means of sponge, or other similar substance, as that has heretofore been done; nor do I claim the invention of a cup, or saving chamber, placed under the bearing of a journal, as cups, open and exposed to the dirt,, and from which the oil could be spilled by the jar of the car in motion, have been used; neither do I claim a washer, or cap, from the hub of a wheel, as that is now applied to common carriages; but what I do claim as my invention, is constructing the box in the manner described, having two recesses, or compartments, in its lower section, into one of which sponge, or other suitable elastic substance, is fitted, so as, when saturated with oil, to lubricate the journal with which it comes in contact, the other chamber being made to receive the oil that flows over from the first compartment, the oil being conveyed to said chambers through a conductor that enters the supply chamber under the journal; the whole being combined substantially as set forth. I also claim the particular manner in which I have constructed the journal and its bearings, grooves and cap, in combination with the foregoing lubricating apparatus, consisting of the fillet, or tongue, and the recess in the bearings for checking the lateral motion of the bearing, and the grooves and washer for retaining the oil, in combination, as set forth."

22. For an improvement in Wire Heddles; Abraham Howe, and Sydney S. Grannis, Morrisville, Madison county, New York, Oc
Heddles have heretofore been made in two parts, jointed together
by a loop at, or near, the eye through which the warp passes, which has been alleged to be an objection, and the improvement in question is for making them in one piece, or in two pieces, jointed at the ends. Claim. "What we claim is the making of such heddles in one continuous piece from end to end without a joint, and this we claim whether said heddles be made of one entire piece of wire recurved at one end, to form the end eye, or of two pieces of wire, each having the end eyes formed by twisting the ends of the wires round in the ordinary manner."
23. For an improvement in the Spiral Water-Wheel; John G. Garretson, Muhlenburg, Pickaway county, Ohio, October 11.
This wheel is formed in the manner of an Archimedean screw, but placed with its shaft vertical, so that it acts directly by the gravitating force of the water; and the edges of the spiral buckets, or the screw, take into cogs on a wheel, (called by the patentee the "waiter wheel,") by which the power is to be transferred to a mill, or other machinery.
Claim. "Now what I claim to be my invention, is the combination of the spire wheel, and the case surrounding it with the wheel which I denominate the waiter, the whole being constructed and operating in the manner set forth, forming a propelling power for mills and machinery receiving and transmitting the power of descending water."
24. For an improvement in the Parlor Stove; Joseph Feinour, Jr., Philadelphia, Pennsylvania, October 11.
We make the following extract from the specification, viz.,-"Upon a quadrangular, or other suitably formed, pedestal, I place a cylinder of sheet-iron, within which is contained the fire place; the lower part of this, which is to contain the fuel, is a low cast-iron cylinder that is lined with fire clay. The pedestal contains the ash-pit drawer, and extends back, so as to receive air in its rear part, four tubes, or colums, through which the draught from the fire may be directed, the upper ends of which enter a heated air chamber similar in dimensions to the pedestal. The fire chamber is surrounded by a cast-iron cylinder, or rather a conical body, which, with the fire chamber, is surrounded by the sheet-iron cylinder that forms the exterior of the stove. The fire grate turns upon pivots, as is well known, and may be shaken up and down. There is a space between the outer cylinder and fire chamber, for the passage of heated air, which is supplied to it by a pipe that passes through the pedestal, to take the air from near the floor, or out doors. This pipe opens into the cylinder, so as to cause the cool air to strike against the fire chamber, and, when heated, passes into the room through apertures in the cylinder. Immediately above the fire cylinder, and contained principally within the hot air chamber, is an air heater, closed at its lower end, which is exposed to the direct heat of the fire, except that there is an opening into its lower part, by means of a pipe from the exterior of the
sheet-iron cylinder, which opening admits air from the room that will become heated, and escape into the room through a grated cover. The pedestal behind the ash drawer forms a draught space for heated air, which may be made to descend two of the columns leading from the upper hot air chamber, and to ascend the other two on its way to the exit, or smoke, pipe, which leads from the hot air chamber into a fire place. By means of a valve in the upper hot air chamber, a direct passage may be allowed from the fire to the exit pipe. There is also a pipe in the pedestal, behind the ash drawer, which forms a part of a partition dividing the pedestal into two chambers, and which, when it is desired to lessen the force of the fire, may be opened for that purpose, whilst the upper door of the stove may remain closed. The air that enters at the opening of the ash drawer will then pass directly back to the columns behind the stove, instead of through the fuel, preventing its free combustion, and the escape of gas into the room, which is apt to occur when the upper door is opened."
Claim. What I claim is the arranging of the damper between the ash-pit and the heated air chamber of the pedestal, for the purpose described. I claim the manner in which I have arranged and combined the fire chamber, the cast-iron cylinder, or cone, the sheet-iron cylinder furnished with openings, and the cool air pipe leading into the space, in the manner and for the purpose made known. I claim the manner of arranging the air heating cylinder above the fire chamber, and passing through the heated air chamber, having also an opening into it for the admission of air, and being furnished with a grated cover for its escape, after being heated in its passage through the cylinder."
25. For improvements in the Rotary Steam Engine; L. A. Stewart, Cross Plains, Robertson county, Tennessee, October 11.
This is for improvements on Murdock's rotary engine, patented in England some forty years since, in which the steam acts against the cogs of two wheels. The improvements are pointed out with sullicient clearness in the claims.
Claim. "What I claim is the manner" of constructing, combining, and arranging the cap and cheek pieces, so as to embrace under the cap but a small portion of each wheel, employing the cap and cheek pieces, in lieu of the close case, or cases, hitherto used in such machines, and introducing the steam through the caps between each pair of wheels. I claim the combining with these caps the weighted levers for pressing them down on the teeth of the wheels, thus preserving them in close contact, without the necessity of any elastic packing. I claim the manner of preventing binding, or cramping, in said pairs of wheels, by the combined operation of the end play of the axles of two of them, and of the play of one of them in the direction of its revolution. I claim the using of the steam on a second pair of wheels, by conducting it from the first pair through the cap of the second pair, in the manner set forth."
