15. For an improvement in the apparatus employed in the process of

Extracting and Rendering Lard, Tallow, and Oil from Concrete substances, and for refining the same; Ebenezer Wilson, Cincinnati, Ohio, October 9.

The material from which the lard, tallow, &c. is to be rendered, is put, bones and all, into a large vertical cylindrical vessel provided with a safety-valve, mall-hole, &c. A perforated steam pipe from a steam boiler is coiled on the bottom, and about six inches above this there is a perforated false bottom, on which the material to be rendered lies to protect the steam pipe and give free egress to the steam. In the middle, the false and real bottoms are perforated with a hole of sufficient capacity for the discharge of the refuse matter; and around this hole the two bottoms are connected with a tube, to the upper end of which a valve is ground perfectly tight, the valve being provided with a rod extending up through a stuffing box at the top of the tank, to afford the means of opening and closing the valve, and downwards, and provided with a screw at the lower end which takes into a nut to fasten and hold it down. The tank is also provided with a try-cock near the top, and six or more other cocks, placed at equal distances apart from near the false bottom to about the middle of the height, for drawing off the rendered lard, &c., the apertures to these cocks being protected by a strainer.

After the tank has been charged, steam of very high pressure is to be admitted for a sufficient length of time to extract all the lard, tallow, &c., after which it is drawn off, and the refuse discharged through the hole by removing the valve.

Claim. Having fully described the nature of the apparatus which I use, and of the process which I follow, for the rendering of concrete fatly substances, I do hereby declare that I do not make any claim to the rendering of such substances by the introduction of steam into open vessels, in which they are contained—this having been previously done; but what I do claim as constituting my improvement, and desire to secure by letters patent, is the manner set forth of arranging and combining the respective parts of such a vessel : that is to say, I claim in combination the vertical tank, perforated faise bottom, and discharging hole-such hole having a cover, to be operated upon in the manner and for the purpose set forth; the said tank being also furnished with a series of cocks, guarded on the interior by a strainer; the whole being so formed and arranged as to attain the proposed end, by means substantially the same with that herein fully made known.”

16. For a Wool Combing Machine ; Ezra Gould, Paterson, Passaic county, New Jersey, October 9.

In this machine combs are arranged on radial bars attached to the face of a disk-wheel, in such manner as to be parallel with the face of the disk, and at right angles with the radial bars from which they project; and these, in combing, act in conjunction with teeth or combs, radiating from the rim of another wheel, and also carry the fibres around, to receive the action of rotating brushes.

Claim.--"What I claim as my invention, and desire to secure by letters patent, is arranging the combs, pins, card teeth, or brushes, in rows, radiating from a common centre, and parallel (or nearly so) with the face of a wheel, when attached to the wheel, or to arms projecting from a wheel, or 10 a plane corresponding to the face of a wheel, or when they are attached to arms simply projecting from a shaft, as herein described. And the employment of a comb, brush, &c., thus constructed, in combination with combs on another wheel, for the purpose and in the manner substantially as described."

17. For an improvement in the Coupling and Stuffing Box for

shafts, specially intended for submerged propellers for Ships ; R. F. Loper, Philadelphia, Pennsylvania, October 9.

The outer tube of the stuffing box, instead of being permanent, is tapped into a metallic casing surrounding it so as to admit of screwing it over the lapped or other joint of the shaft, so that when this tube is drawn in, the two shafts can be separated, and if desired, the propeller drawn up out of the water, and when screwed out, passes over and prevents the two shafts from beiuy separated.

Claim.—“Having thus fully described my improvements, what I claim therein, and what I desire to secure by letters patent, is the before described mode of employing the cylindrical tube for the double purpose of a coupling box and stuffing box, by combining it with the coupled shaft and with the other portions of the stufling box; by which arrangement much room is saved, and great simplicity attained -all as herein described.”

18. For an improvement in the mode of Setting Logs on the carriages

of saw mills; John B. Squire, Liberty Township, Crawford county, Ohio, October 9.

The slides on the head and tail blocks, to which the dogs for securing the log are attached, are provided with a toothed rack operated by a hand on one arm of a toggle joint, the other arm being jointed 10 its appropriate block, which is also provided with what the patentee terms a “driver," one end of which bears against the joint of the toggle, and the other projects beyond the face of the block susticiently far to strike against a rest on the floor of the mill, when the carriage is run back, to force the slide the distance required for the setting of the log.

Claim.-“What I claim as my invention, and desire to secure by letters patent, is the method of moving the slides of the head and tail Llocks simultaneously, as the carriage is gigged back, by means of the toggle-joints, combined with the slides to which the log is dogged, and the drivers for operating the toggle-joints in the manner and operated in the way above described for setting both ends of the log simultaneously, whilst the saw is in the groove of the head block.”
