the length of the arms, between the periphery of the outer plate and their outer extremity, into three parts. The centre plate has a flanch with notches, into which the arms fit, and the braces are drawn tight towards the centre of the wheel, by means of radius screw bolts that pass through their middle and the flanch of the centre plates.

Claim. "What I claim, and desire to secure by letters patent, is the within described manner of inserting and drawing up the braces, by means of brace-bolts attached at their inner ends to the circular plate which receives the ends of the arms; said bolts being furnished with screw nuts, which are to bear against the middles of said braces, as described and represented; the braces being inserted and retained in place by means of short tenons, and left free to slide within the arms, as set forth. I also claim, in combination with the foregoing mode of bracing by means of the brace-bolts, the employment of the wedges between the inner ends of the arms."

4. For an improvement in the machine for Turning Straight, Curved, or Taper, Work-such as Fork and Shovel Handles; Collins & Wistar, assignees of Stacy Costill, Philadelphia, Pennsylvania, June 7.

The piece of wood to be turned is fixed to a mandrel, and passes through a hole in a plate attached to a slide rest. The hole in the plate is provided with three segments that slide in radial grooves made in the plate for the purpose of regulating the size of the hole to suit the size of handle required to be turned. The segments are all moved together by a second plate, which has three eccentric grooves cut in it, that receive projections from the back of the said segments. The turning of the last mentioned plate at the back of the main plate will, therefore, cause the segments to approach or recede froin the centre. The cutting is effected by a cutter attached by proper fixtures to one of the segments.

Claim."What I claim as of my invention, and desire to secure by letters patent, is the cutter in combination with the movable segments, and these thus combined in combination with the eccentric grooves in the plate, for the purpose, and in the manner, described."

5. For an improvement in the Key for Extracting Teeth; Moses J. Hill, Bloomfield, Lagrange county, Indiana, June 7.

This patent is granted, as stated in the claim, "for combining a friction roller with the bolster of the ordinary key for extracting teeth, in such a manner as that said friction roller shall constitute the bearing part of the bolster in the operation of extracting a tooth."

6. For an improvement in the Saw Mill; James B. Lowry and Philander Eggleston, the former of North East, Erie county, Pennsylvania, and the latter of Mayville, Chatauque county, New York, June 11.

This patent is for an alleged improvement on that kind of saw mills

in which two saws are used; but instead of being strained in a gate, they are attached to chains that are connected with two vibrating beams, the ends of which are segments of circles. The claim is confined to the combination of a slide and stirrup, by which the saws are attached to the chains, and by which they are guided.

7. For an improved mode of Fastening Doors on the inside, called the "Traveler's Security;" Benjamin H. Green, Princeton, Mercer county, New Jersey, June 11.

This instrument is for fastening doors from the inside which are not provided with locks or bolts. Two claw pieces, one of which is put against the floor, and the other against the lower rail of the door, are united together by a right and left handed screw, provided with a thumb piece in the middle for turning it, and by which the claws are forced apart.

Claim."What I claim as my invention, and desire to secure by letters patent, is the manner of constructing the traveler's security by combining the two claw pieces with an intermediate screw, furnished with a thumb piece for turning the same, as described."

8. For an improvement in the Bee Hive; James Le Pataurel, Chandlersville, Muskingham county, Ohio, June 11.

The proposed improvement is in that kind of hive in which the honey is formed in glasses, and by which the patentee says he is "enabled to take out the honey, &c., from the hive, without destroying the bees, and without running any risk of being injured by them." The glasses are made with a stem which fits a hole in the cover of the hive, and are provided with a hole at top, and they are arranged in pairs at a suitable distance apart, to receive two pipes that branch out from a furnace for generating smoke. When it is desired to drive the bees from a set of glasses into the apartment below, the pipes are applied to the glasses, and a composition, consisting of 3 oz. of sulphur, 4 oz. of pitch or tar, 1 oz. of tobacco, and oz. of grease, is put into the furnace, which generates a smoke that expels the bees. The glasses are then removed, and the holes closed by means of movable covers. When it is desired to drive the bees from one apartment to another, the pipes of the furnace are introduced through holes in the cover of that apartment from which they are to be driven.

Claim. "What I claim as my invention, and which I desire to secure by letters patent, is the manner in which the glass bows, or hives, are combined and adapted to the apertures in the cover, by being formed with hollow stems, as set forth. I also claim the furnace constructed and combined with the hive, as set forth."

9. For improvements in Door Locks and Latches; Geo. W. Wilson, Nashua, Hillsborough county, New Hampshire, June 11.

The claim in this patent rests upon the making of the lever, which acts upon the latch, with a heavy weight and disconnected from the

latch, so as to cause it and the knobs to return to a stationary position, and thereby, whenever the door is closed, to permit the latch to recede and advance independently of said lever; and also to the combination of this with a weighted, or gravitating, latch; to the combining with the main bolt of the lock another bolt, to be operated by an extra key; and to constructing the holding lever of the main bolt so that the key cannot be withdrawn unless the holding lever has been brought to its proper place; and, finally, to a peculiar apparatus for giving an alarm should any one attempt to open the lock; this apparatus consists of a slide, spring, and spring catch, to be used in connexion with the extra bolt, and which, when disconnected therefrom, starts the alarm.

10. For improvements in the Horse Power; Samuel H. Little, Gettysburg, Adams county, Pennsylvania, June 10.

The patentee informs us that the improvements consist in the "manner of constructing this machine, by which it is made capable of being adapted to the power of two or four, or any other varying number of horses." The rim of the main driving wheel, with the cogs thereon, is cast separately from the arms, by which it is connected to the shaft, there being gains, or notches, cast in the inner side of said rim, into which the ends of the arms fit, and by which it is capable of being removed from one set of arms, and placed upon another set, of the same size. Immediately over the arms above named, and connected with them, are the sunken troughs which receive the horse sweeps. The weight of the wheel, arms, &c., is supported by conical friction rollers, which have their bearings in braces cast with the said arms. This wheel revolves on a stationary pivot rising from the cap of the machine, and gears into a pinion on the shaft of the second wheel. The upper ends of the shafts of the second and third wheels are adapted to receive the main wheel when it is desired to employ less power. The lower gudgeon of the shaft of the second wheel is received in the upper part of a standard projecting from the bed of the machine, and this standard is also adapted to the reception of a shaft, instead of this, provided at its upper end with arms and troughs for the horse sweeps; and at its lower end with arms for the main wheel; the said arms being also provided with conical friction rollers that travel on the upper part of the standard, which is made conical for that purpose. By these various arrangements this machine may be conveniently and readily adapted to the power of one, two, or more, horses.

The claim makes reference to the drawings, and is to the manner in which the cross, or troughs for the sweeps, the arms and rim of the driving wheel, and the friction rollers, are arranged and combined, so that they may be shifted from one shaft to another, and by which the wheel may be adapted to other arms of the same size; and also to the manner of arranging the extra shaft so that it may take the place of the shaft of the second wheel.

11. For improvements in Marine Steam Engines; Charles W. Copeland, New York, June 11.

The cylinders, in this arrangement of the engine, are inclined at an angle dependent upon the depth of the hold, and the length of stroke; and they are fastened to inclined beams extending from the paddlewheel shaft to the kelsons, said beams being connected with the kelsons along their whole length, by other beams, and by bolts-the whole constituting truss-frames, which sustain and divide the weight and jar of the engines. The condensers are directly under the upper end of the cylinders, and the channel-plates run between the kelsons. The lower end of the air pumps, which are inclined, as well as the cylinders, are secured to the ends of the said channel-plates, and the hot wells to their upper parts; the delivery valves are placed on the upper side of the channel-plates. The pistons of the air pumps, in this arrangement, are solid; and the whole apparatus is rendered compact, and placed within the reach of the engineer. The side pipes are placed above the cylinders, the steam chests at each end thereof, and the valve stems running down in front of the heads of the cylinder to the rock shaft. The feet are attached directly to the stems, instead of lifting rods, and are acted upon by the toes of the rock shafts, the two rock shafts being connected together by a rod.

Claim. "What I claim as new, and as constituting my invention, is, first, the placing of the cylinder in an oblique direction, with its lower end near to the bottom of the vessel, and allowing it to stand at such angle as is required for the connecting of its piston rod with the crank on the shaft of the paddle wheels, in combination with the condenser, channel-plate, and air pump, arranged and located as described. I do not claim the mere placing of the cylinder of a steam engine obliquely, as this has been done for other purposes; but as I produce a new and useful effect, by so placing the steam cylinder and its appendages in the combination above claimed, on board of vessels for navigating the ocean, I limit my claim to the so placing them under the said combination as to attain the object fully made known. Secondly, I claim the manner of arranging and working the steam and exhaust valves as set forth, the same being effected by a direct action, that is to say, without the employment of the lifting rods and lifters usually required for that purpose. Thirdly, I claim the manner of combining and arranging the condensing apparatus, the air pump being placed at the same angle, or nearly so, with the cylinder, and attached by its lower end to the channel-plate, the delivery valve being also placed on the upper part of the said plate; the combination intended to be claimed under the last head consisting in the arranging of the several parts enumerated, that is to say, the air pump, the channel-plate, and the delivery valve, substantially in the way described."

12. For an improvement in the Fulling Mill; Sidney E. Coleman, West Haven, Rutland county, Vermont, June 11.

The cloth is put into the machine, with the usual folds, and passes

between rollers arranged in a box, which have different degrees of motion communicated to them by band wheels and bands, or by coged wheels.

Claim. "I claim as my invention, fulling cloth by means of revolving rollers, or cylinders, said rollers being arranged in a box, or casing, and operating as described."

13. For an improvement in the Saw Mill; William Bryant, Nashville, Tennessee, June 11.

The saw gate and fender posts of this mill are placed at an angle of about 45 degrees with the plane of the carriage, instead of being perpendicular to it.

Claim. "What I claim as my invention is, placing the guides which direct the saw at such an angle with the log, or timber to be sawed, that the shavings in being cut are peeled, or raised, and carried forward by the teeth of the saw, in the lengthwise direction of the timber sawed."

14. For an improvement in the Rotary Steam Engine; Hernon Smith, Sunbury, Delaware county, Ohio, June 11.

In this rotary engine there are two pistons on opposite sides of the wheel, or drum, each being united by a rod passing through the diameter of the wheel, said rod being provided with a loop in the middle, to pass over, and slide on, the shaft. This double piston is operated, or shifted, during the rotation of the wheel, by means of a cam on its outside, which cam is a semi-circle, with the ends running out from the circle to catch a pin on the piston, and thus shift it.

Claim. What I claim as my invention, and which I desire to secure by letters patent, is the peculiar form and construction of the double piston moving over the shaft, in combination with the semicircular cam outside the steam chamber, as described, for changing the position of the pistons as the wheel revolves."

15. For an improvement in the Lamp for burning Oil and Camphine; Christian and Charles Richman, Philadelphia, Pennsylvania, June 11.

The wick tube of this lamp, which is on the principle of the Argand, is provided with two holders that are jointed to the lower end of the tube, their upper ends being semi-circular, and made to hold the wick against the upper end of said tube. This holder slides on the inner cylinder of the lamp, a pin on its inner side passing into a groove on the outside of the cylinder; and on the outside of the holder is placed the runner, which has a spiral groove running from its upper end to near the bottom, into which fits a pin from the wick holder, so that by turning the runner the wick holder will be made to rise or sink vertically. The upper end of the runner is connected with the glass holder. The button is made conical and of glass, instead of being flat and of metal.
