Claim. "What I claim as my invention, is the combination, in the traveling table motion of planing machines, of two racks, L' L2, sheets 1 and 2, operated on by two separate pinions, MN, one of which is made adjustable in the manner shown, by set screws mmmm, with accompanying parts, and so arranged that the pinions M N may be set as to alternately operate, the one to drive the table forwards, and the other to drive it backwards, for the purposes herein set forth, and operating as shown and described, or in any manner substantially the same."

48. For Improvements in Hydraulic Blowers; Jeremiah Darling, Cincinnati, Ohio, De

cember 24.

"My invention consists of an apparatus by which a continuous and powerful blast is produced for smelting, forging, and other purposes, which works with little friction and requires but a small power to drive it, and being simple in its construction is not expensive; and it is not liable to get out of order. One great advantage over cylinder blowers is, that it does not require to be stopped to pack pistons, &c., which, in smelting operations, frequently produces injury to the iron by stopping the blast. All that is necessary to keep this apparatus continually in action, till worn out, is to keep up the supply of water, which can be done while in action."

Claim. "Having thus fully described my improvements, what I claim therein is, 1st, the apparatus substantially as above described, consisting of a revolving drum, partly filled with water, and provided with chambers, valves, &c., which cause the air to enter at one hollow journal, and escape in a compressed state at the other, for the purpose of producing blast as set forth.

"2d, I claim the manner of separating the water accidentally mixed with the blast, by means of the partitions and cells in the chambers (l and n.)

❝3d, I claim the pipe (u) for conducting the water accumulated in the chamber (n) to the hollow journal (c) and returning it to the drum, substantially as described."

49. For an Improvement in Vats for Tanning Hides; Lewis C. England, Williamsburgh, New York, December 24.

"The nature of my invention consists in an improvement on such vats, or tanks, used in the various processes of preparing leather, as are fitted with revolving handles. In vats of the usual make, the skins or hides cannot be kept in a state of agitation throughout the whole of the vat, as some will lodge in the lower corners, &c., and the handling of the remainder then requires a greater expenditure of power, in consequence of the increased resistance. By the construction in such vats of a semi-cylindrical bottom of slats, I am enabled to effect the handling of the hides, in the various processes of liming, bailing. scouring, washing, and tanning, far more rapidly and economically than in vats of the usual make."

Claim. "I do not claim herein the use of the revolving handles, as already secured to me by letters patent bearing date of June 19th, 1847; but what I claim as of my own in vention, is the slats, as described, in combination with the vat and the handles, substan tially in the manner and for the purposes herein set forth."

50. For an Improvement in Printing Presses, Charles W. Hawkes, Boston, Massachusetts, December 24.

56. For Improvements in Looms for Weaving Figured Fabrics; Samuel T. Thomas, Lowell, and Edward Everett, Lawrence, Massachusetts, December 24.

"Our improvement in the jacquard loom consists of an arrangement and combination of harness shafts or bars, as a substitute for the knot cord, by which arrangemement we distribute the many mail cords or heddles of the knot cord at any required distance apart, and disconnected from each other, along the length of the horizontal harness shafts or bars, by which a very material advantage is gained, as we thus produce a much less angle upon the mail cords or heddles, than by giving a more uniform strain upon the warp, which renders the loom applicable to broad work; also, by rendering each mail cord or heddle independent of every other mail cord, and capable of being transferred from any one harness shaft to any other harness shaft or bar, the operator is enabled to change the mounting or cording with greater facility than by the mode heretofore adopted.

"Our second is to be found in the peculiar means or manner of producing the rotary movement of the pattern prism."

Claim. "What we claim is the improvement on the jacquard loom as herein described, to wit: the horizontal harness shafts or bars, of such length as may be desired, (according to the width of the cloth;) upon which the several mail cords or heddles, which constitute the harness or entire mounting, are distributed at any required distance from each other; together with their hooks, pins, loops, or holes, upon or in which the several mail cords or heddles, which are caused to be raised or operated upon by one needle, or distinct movement, are separately fastened or attached.

"We also claim the improvement for producing the rotation of the pattern prism; the same consisting in combining with the machinery that advances the pattern prism, other mechanism, which, at the same time, shall produce a movement of the draw pawl in an opposite direction as described."

57. For an Improvement in Mills for Grinding; Joseph N. Walker, Cincinnati, Ohio, December 24.

"The nature of my invention consists in constructing a portable mill with the shell of cast iron, and is arranged so as to keep the entire inside clear of dirt or dust, and at the same time have easy access to the machinery within."

Claim "Having thus fully described my invention, what I claim therein as new is the combination of the hollow spindle A, feeding tube E, and adjustable screw a, with the gimbal i, when said gimbal is placed above the openings through which the grain or other material to be ground passes to the surfaces of the stones, as herein fully set forth and represented, for the purpose of having an uninterrupted feed through and past the gimbal.”

58. For an Improvement in Hot Air Furnaces; George E. Waring, Stamford, Connecticut, December 24.

"The object of the first part of my invention is to distribute the heat equally over the radiating surface, and, with this view, consists in carrying the heat and products of combustion up to the top of the furnace, and then causing them to descend between a cylinder of tubes surrounding the fire-pot and the exterior casing of the furnace; the said tubes being connected together by short partitions, thereby forming an annular flue between them and the external casing of the furnace down which the heat and products of combustion descend.

"And the second part of my invention consists in the use of a distributer, which not only admits of the free circulation through it of the external air, but by means of arched passages or channels opening into the annular flue above mentioned, causes the heat and products of combustion (which have been brought down the said cylindrical flue) to enter the exit chamber which forms the base of the furnace, and back to the smoke pipe.

"And the third part of my invention consists in admitting the air to be warmed into a chamber warmed by radiation from the fire-pot, and from the descending current from the fire, and then causing the same to pass up through the body of the furnace, through a series of tubes arranged in the form of a cylinder, by the radiation of the heat from the fire-pot which they surround, and from the descending current which surrounds them."

Claim. "What I claim as my invention, is the annular flue between the cylinder of tubes and the external casing of the furnace, for the purpose of distributing the heat equally over the external casing, substantially as described.

"I also claim the distributer, or annular distributing chamber, provided with arched passages for the purpose of carrying the heat and products of combustion to the exit chamber, and which also admit of the free circulation of the external air in and around the fire-pot, substantially in the manner and for the purpose described."

59. For an Improvement in Machines for Weighing Grain; Samuel R. Wilmot, Lafayette, Indiana, December 24.

"The nature of my invention consists in the peculiarity of the weighing beam; likewise the manner of arranging the gate so as to tilt the vibrating or weighing scale by the closing of said gate, which, on its return, strikes the gate-rod and raises it; also the manner of stopping the operation of the machine by means of a bolt or catch, thrown from the indicator at any given period."

Claim. "What I claim as new, is the employment of the gate-rod f, connected to the sliding gate e, and weighing beam d, in combination with the said sliding gate, and weighing beam, constructed and operating as aforesaid, for opening and closing the gate, to admit the grain to the dish or scale, or exclude it therefrom at the required periods, by the ascent and descent of the dish or scale, during the operation of weighing and discharging the grain, as herein fully set forth.

"I also claim the manner of attaching the vibrating weighing scale to the weighing beam d, so that the said weighing scale, as soon as the required quantity of grain shall have entered it, shall descend and close the gate, and bring the hammer-end, j, of the gaterod against the lip of the dish or scale, and cause the scale to turn on its centre m, and immediately ascend and strike the gate-rod, and re-open the gate, and assume its former position for another weight of grain,-every operation of the weighing apparatus being indicated by an index of the ordinary construction affixed to the end of the scales-the said scale being arranged below a hopper of the ordinary construction.

“I likewise claim turning the short end of the weighing beam upwards, in the manner
