33. For a Gauge for Indicating Pressure of Steam, &c.; George Faber, Canton, Ohio,

September 16.

"This invention is for the purpose of ascertaining the degree of pressure to which elastic fluids are subjected under certain circumstances; as, for example, in the generation of steam in ordinary steam boilers; and is chiefly intended for application to such boilers. The principle upon which the invention is based, is the power produced by a free current of an elastic fluid impinging upon an inelastic substance, as a disk of metal, &c., the velocity or pressure being ascertained by the distance the disk has been moved by the force of the current."

Claim. "What I claim as my invention is, combining with the steam tube, the disk and spring, so arranged that the force of the current of steam impinging upon said disk, can be ascertained by the extent to which the spring is expanded, and thus can be known the comparative pressure in the boiler or other vessel, necessary to give the required velocity to the current, to produce different degrees of expansion of the spring, substantially as herein set forth."

34. For an Improvement in Apparatus for Draining Sugar; Smith Gardner, City of New York, September 16.

"The nature of my invention consists in arranging one or more series of pans, with their bottoms perforated or made of wire gauze, and each provided with a pan or receiver below, to catch the molasses; and provided with an aperture for the passage of the current of air; the whole being otherwise made air-tight, so that the current of air forced into the first shall, in producing the required effect, pass to the second, to produce a like effect there; thence to the third, and so on throughout the series, and thence in like manner through other series, if desired."

Claim. "What I claim as my invention is, combining two or more straining pans with molasses or receiving vessels below each, substantially as described; the said pans being provided with a discharge pipe or tube, substantially as described, so that the current of air shall pass from the lower part of the first to the upper part of the next, through the series, and so arranged as to retain the molasses or other liquid parts; and this combination I claim, whether the said succession of pans be used in one or more series, as described."

35. For an Improvement in Stone Drilling Machines; Henry Goulding, Boston, Massachusetts, September 16.

Claim.-"Having thus described my new drilling machine, I shall state my claim as follows: What I claim as my invention is, 1st, A power-drilling machine, in which the drill is driven by a vibrating hammer, operated substantially as herein above described.

"2d, I claim stopping the "feeding forward" of the sliding frame and drill, when the latter does not penetrate the rock sufficiently, or to the usual depth, at each blow, by keeping the pawl out of the feeding ratchet, excepting when the drill goes in the requisite length, by means of the combination of the forked vertical lever, connected with the drill shaft, the horizontal lever, and the spiral spring, operating substantially as herein above set forth.

"I also claim, drawing the edge of the drill away from the bottom of the hole, when the tool is being turned, by means of the inclined claw or fork, operating with a collar on said drill, substantially as herein above described."

36. For an Improvement in Machines for Dressing Millstones; Erastus W. Hazard, Binghampton, and Charles H. Jenner, Rochester, New York, September 16.

"Our invention consists in combining with the lever which operates the feed hand or hands, and which receives motion from a rotating cam or tappet, a weighted lever, or the equivalent thereof, which falls by its weight the moment the lever is carried back to give one feed motion, so that the end thereof shall act as a stop to arrest the feed motion, that the cutter may continue to strike in the same place, until the attendant lifts up the lever to permit the feed motion to continue."

Claim. "We claim, in combination with the feed lever operated by the cam to work the feed bands, the employment of a weighted stop lever, or the equivalent thereof, acting

in the notch of the lever, substantially as described, which said stop shall be self-acting, to stop the feed motion, that the cuts may continue in the same place, until the feed motion is re-started, and thus insure the cutting of the stone to the required depth, whatever may be the texture thereof, as described."

37. For an Improvement in Processes of Making Bronze Powder; Leopold Brandeis, City of New York, September 16.

"The nature of my invention consists in producing the powder, by rolling it between steel or iron tempered rollers, instead of the old producing (kept secret), to beat the metal to dutch leaf, and grinding it, to give it a bright and brilliant surface, by covering the bronze with soap, instead of grease and oil, and polishing the surface by application of polished rollers."

Claim. "What I claim as my invention is, making metallic bronze powder of copper, tin, spelter, or their alloys, by running them through iron or steel rollers, substantially as described. Also, the application and manner of application of soap, to make the bronze bright, and brilliant, and durable."

38. For an Improvement in Stoves; Gardner Chilson, Boston, Massachusetts, September 16.

Claim. "What I claim as my invention is, the combination of the latch pin, the ratch bar acted upon by a spring that constantly tends to disengage it from the latch pin, and the foot lever, with the movable jaw of a vise; these several parts being constructed, arranged, and operating as herein set forth."

40. For an Improvement in Weavers' Temples; Arnold Jillson, Woonsocket, Rhode Island, September 16.

Claim. "What I claim as my invention is, connecting the movable jaw to its point of suspension, by an arm, or equivalent, in such a manner that the point of suspension will be nearer the middle of the cloth than its other extremity, which extends out towards or beyond the selvedge at such an angle, that the jaws of the temple will be released by the cloth, as it is spread by the action of the reed upon the warp, when it strikes up a thread of weft, and closed by the contraction of the cloth, caused by its own elasticity, as the reed leaves it; so that the cloth, by its own action, is released when the reed advances, and is griped and held as it recedes; thereby dispensing with the strong spring, wedge, and other devices, heretofore used for operating the jaws of temples."

41. For an Improvement in Leather Splitting Machines; Alpha Richardson, North Enfield, New Hampshire, September 16.

Claim.—“Having thus described my improved leather splitting machine, I shall state my claim as follows:

"2d, I likewise claim the employment of a temporary cylinder and tubes, in combination with the revolving vessel and cross bar, for cooling, or warming, and agitating the milk, by its precipitation thereon, as caused by the circular motion conveyed to the milk, and interrupting or arresting effect produced, substantially as shown and described."

46. For Improvements in Machines for Scutching and Hackling Hemp and Flax; Owen W. Grimes, Paducah, Kentucky, September 23.

"The nature of my invention consists in the manner of throwing, the teeth in and out of the drum, with which they revolve, to any desired distance, while the machine is in operation, so as to give more or less hold on the hemp or other material, or drawing them. entirely within the drum, when the material becomes entangled, and liable to choke or break up the machine; and also the method of allowing the teeth, when out, to fall back, or yield sufficiently far to allow the material to slip over them, when. too great a strain is suddenly brought upon them, and recovering their proper position again after passing said obstruction."

Claim.-"Having thus fully described my invention, what I claim therein as new is, the method herein described, or any other means essentially the same, of throwing the teeth in and out of the cylinder or drum, at pleasure, whilst in motion, so as to present a

greater or less length of teeth to the hemp, or drawing them entirely within the cylinder, in case the hemp should become entangled, and likely to break up the machine.

"2d, I claim, in combination with the bar holding the teeth, the spiral spring, for allowing Said bar to yield to knots or other obstructions, and for drawing back into proper posi tion the said bar, after it is released from said obstruction.
