around a pulley at the top of the frame, then under another pulley, attached to each end of the follower, and is then made fast to the upper part of the frame. On one end of the shaft of the scroll wheels there is a large wheel, called the "power wheel," from which a chain, or rope, passes to a capstan, or other first mover.

The claim is to the "combination of the power and scroll wheels."

2. For an improvement in the Current Water Wheel for Mills; Noadiah N. Hubbard, Randolph, Portage county, Ohio, April 2.

This patent was obtained for an improvement in the manner of applying chutes to the spiral current wheel. Heretofore two chutes have been placed at the forward part of the screw, so as to concentrate the current; but in all cases the current thus concentrated has been thrown upon the first thread of the screw, and the present improvement is in so placing these chutes that the current shall be directed upon different parts of the length of the thread. The patentee says: "I am aware that the force of the current to be thrown upon a wheel has been increased by chutes placed at an angle with the axis of the wheel, so as to concentrate the current upon it, and this I do not, therefore, claim as my invention; but what I do claim as my inven tion, and desire to secure by letters patent, is the employment of two or more sets of chutes, or regulators, in combination with a spiral wheel, so as to throw the current upon different parts of the thread, or spiral, along its length, as described."

3. For a method of Wetting Flannels and other Cloths previous to Scouring or Milling; Joseph W. Hale, Haverhill, Massachusetts, April 2.

A colander, pierced with numerous small holes, is attached to a reservoir, or tauk, of water, by means of a pipe, the orifice of which is regulated by a valve, to which a cord is attached having a weight at its opposite end, for the purpose of keeping the valve opened when desired. A roller is placed at one end of the frame, and two at the other end, and the cloth in going from the single roller to the double set, by which it is drawn through regularly, passes under the colander and receives the spray from it.

The claim is to the combination of the tank, or reservoir, valve, rollers, and the colander.

4. For improvements in the machine for Cutting Crackers; William Perkins, Boston, Massachusetts, April 2.

A shaft that runs across the frame of the machine gives motion to another shaft, on which is a segment cog wheel that takes into a cog wheel on an under feed roller, and from this motion is communicated to the upper feed roller, and the apron that carries the dough under the stamping apparatus, and conveys the cut crackers from under it. As the wheel that communicates motion to the under feed roller has cogs only on a part of its circumference, the dough will be fed at in

tervals, and those intervals are made to correspond with the time required to stamp the crackers, which is effected by a cam on each end of the shaft of the segment wheel, said cam actuating a lever connected, by a rod, with a toggle-joint that operates the stamping apparatus.

The claim is to "the arrangement of machinery which gives motion to the feed rollers and endless apron, in combination with the arrangement of machinery which operates the stamping apparatus; and also to operating the feed rollers and endless apron, so that they may be alternately at rest and in motion, by means of a geared pinion, having a portion of the teeth of its circumference removed, in connexion with the other machinery intervening between said pinion, feed rollers and apron; also operating the stamping apparatus by means of a cam or cams, in connexion with the toggles and other intervening machinery."

5. For an improvement in the Tuyere for Forges; Elias Kaighn, Camden, Gloucester county, New Jersey, April 2.

The ash box of the forge is to be surrounded by a flue, which has an opening to receive the nose of the bellows, and the blast passes from the flue into the ash box, through apertures made in the sides thereof, and from the ash box into the fire, through holes made for that purpose in its top plate; the ash box has a bottom which is removable at pleasure.

Claim. "What I claim as my improvement, and wish to secure by letters patent, is the construction of the tuyere with a flue surrounding the ash box, in combination with said ash box, as set forth. Also, in combination with the foregoing, the arrangement with the upper surface of the tuyere, as the hearth of the forge, and the perforated cover for admitting air to the flame, &c., as set forth.".

6. For a Cattle Pump; Shively Stadon, Greenwood, Columbia county, Pennsylvania, April 2.

The patentee says:-"In my apparatus the weight of a single animal, or of more than one, is made effective in the raising of water, by their standing upon a movable platform, close to which the trough is situated, from which they are to drink, said platform being so connected with a pump as that by its depression it shall operate upon the pistons of the pump, and of course give a supply of water."

The claim refers throughout to the drawings, and is confined to the special arrangement of the apparatus, as described and represented.

7. For a mode of Healing Reducible Hernia; Zophar Jayne, M. D., Greene county, Illinois, April 2.

The claim affords a sufficiently clear description of the improved mode of healing reducible hernia, and is in the following words: "What I claim as my invention, and desire to secure by letters patent, is, first the injecting into the hernial or peritonial sac, or into the common cellular membrane, or parts in, at, or about, the abdominal

or femoral rings, or openings, wherever the hernia may occur, of an essential oil, or other stimulating or exciting fluid, for the purpose herein fully set forth, whether the same be done or injected by means of the syringe herein described, or by any other instrument adapted to that purpose; and secondly, I claim the constructing and using of a syringe for the above purpose, having a sharp-pointed beak, and a lateral opening therein, substantially as described.

8. For an apparatus for Heating Water and Steaming Vegetables; Asa Munger and James S. Marsh, Auburn, Cayuga county, New York, April 2.

This apparatus consists of a boiler made of two concentric cylinders, the space between the two being for the water, and the furnace being arranged within the inner cylinder. A tubular worm is coiled within the first chamber, its upper and lower ends opening into the boiler. Two tubes branch off from the boiler, one from the top and the other from near the bottom, and connect with the bottom of a tub, from which the steam is conveyed, by a pipe, to the steaming apparatus.

Claim." We do not claim to be the inventors of the worm in the fire chamber, nor of the combination of the tub and boiler, without the worm, but what we do claim as our invention, and desire to secure by letters patent, is the combination of the worm in the fire chamher with the boiler and tub, for the purpose and in the manner set forth."

9. For an improvement in the Joints of Spectacle Frames; Thomas Eltonhead, Baltimore, Maryland, April 2.

"It has heretofore been the practice in forming the frames of spectacles of metal to divide the end-pieces, which are soldered to the rims containing the glasses into two parts, and to connect these two parts together by means of a screw. The joint pin has been affixed to one of these parts, and the side, or temple pieces, have had the tubes through which the joint pin passes soldered to them. In my improved construction I make the end pieces solid, instead of dividing them into two parts, and into this solid piece I file a notch, to receive the end of the temple piece, which is to be adapted thereto, and a hole drilled through for receiving the joint pin."

The claim is to this manner of forming the joints, which not only abridges the labor in making them, but leaves the metals in a condensed state, it not being heated after, having been hardened under the hammer. The glasses are to be snapped in like watch glasses.

10. For improvements in Corselets for Medical purposes; Alanson Abbe, Worcester, Massachusetts, April 2.

The patentee informs us that "the corselet consists of a back piece, and two side pieces, which are united to, and open from, the back piece by a hinge of metal, cloth, or other material, fixed at the top,

and in front are laced with strings. These are made, when connected, to enclose the breast, shoulders, and the upper part of the back, and are adjusted to the shape of the wearer, so as to represent the figure of the body of a well formed person. The corselet affords a support to the frame, and may be advantageously used to prevent, or remedy, distortions of the spine or chest."

The respective parts of the corselets are formed in a mould of metal, wood, plaster, or other suitable material, of the desired form. The claim is to the "mode of manufacturing corselets by forming them of any suitable material upon a mould, or between double moulds, as specified."

11. For an improvement in the Cheese Press; Job Arnold, Harmony, Chataque county, New York, April 2.

The bed of this press is movable, as is also the follower. The bed slides up and down, and has a cog wheel, or pinion, at each end, the axes of which wheels have their bearings in the bed; these wheels gear into two permanent racks attached to the sides of the frame, and as the bed of the press slides up and down, the cog wheels, or pinions, are turned by the racks. There are two levers under the bed, and two above the follower of the press. The levers above, and those below, are connected together by rods, or links, joined to one of their ends, the other end of each pair being connected, by means of ropes, or chains, with the arbor of the cog wheel on each side of the bed. The fulcra of the upper levers are in the follower, and those of the lower, in the bed of the press. The result of this arrangement is, that any weight placed on the movable, or sliding, bed, will cause it to descend, which will turn the wheels, and by means of the ropes, or chains, on their arbors, the ends of the levers to which the chains are attached are drawn together, and as their opposite ends are connected together, the follower is forced down upon the cheese, or other articles placed on the bed.

Claim. "What I claim as my improvement, and wish to secure by letters patent, is the combining of two sets of levers, one set being arranged above the follower, and the other below the movable bed, or press bottom, with the aforesaid follower and movable bed, and said levers being connected and operated as set forth."

12. For improvements in the Rotary Steam Engine; Isaac N. Whittlesay, Vincennes, Knox county, Indiana, April 2.

"The general construction of my improved engine," the patentee says, "is similar to that of some others which have been heretofore constructed, but I have made such improvements thereon as are intended and calculated to obviate some of the difficulties which have been experienced in its action. The principal of these improvements consist in the employment of the steam to open and close the sliding valves, and in the arrangement of some of the other parts by which its action is governed."

Within a hollow case, of the usual construction, "revolves a drum, which carries two valves, to be operated by the action of the steam, which action causes the said inner drum, with its shaft, to revolve in the ordinary way. The valves, which are connected together by a rod, slide into recesses made for them in the drum, which is hollow towards the shaft, for the reception of a disk attached to one of the heads of the outer drum. This disk is at some distance from the head plate to which it is attached, and the space between them is divided by a partition, so as to divide the induction from the eduction pipes. The steam introduced through the induction pipe passes into the hollow space of the inner drum, acts against the inner end of one of the valves, which is thus forced out, and then passes through a hole by the side of the valve into the steam chamber, and impels the valve and inner drum by its reaction on a stop attached to the inner periphery of the outer drum. The openings which admit the steam into, and allow it to escape from, the drum, must be so regulated as to correspond with the position of the stop. The steam may be made to enter the space between the two drums on either side of the valves by a shifting plate, which opens an aperture on one side as it closes the one on the other side, so that by shifting this plate, the motion of the engine may be reversed. The claim refers throughout to the drawings. It is confined, however, to the manner of protruding the valves by the elastic force of the steam, acting behind them by an arrangement of parts similar to that above described; and also to the manner of reversing the motion of the engine, by shifting the plate, as above indicated.

13. For an improvement in the machine for Cutting Staves; Cephas Manning, Acton, Middlesex county, Massachusetts, April 10. This machine cuts the staves from a block of wood by means of a knife, or knives, attached to two revolving disks on a shaft. Between the knife and the shaft there is a bar, extending from disk to disk, on which two holders are placed, armed with the necessary cutters for forming the bevel and groove, and for cutting off the ends of the staves. The position of these holders may be shifted on the bar, so as to adapt them to any length of staves, they being made fast by means of a set screw. The bar should be so situated, with reference to the cutter, which separates the stave from the block, as to cut the bevel, &c., before the stave is cut from the block.

The block is moved forward by means of levers, palls, and a ratchet wheel, which need no description, and these are so arranged as to be thrown in and out of gear, at pleasure, by the aid of levers and catches.

Claim. "I claim the arrangement of the holders of the cutters for forming the bevel and groove, and for cutting off the ends of the staves, on curved or straight bars, or similar contrivances, so that they may be adjusted to cut staves of different lengths, and preserve the bilge of the stave, as described."

The particular arrangement of the machinery by which the pall and ratchet wheels are thrown out of gear, is also made the subject
