manufacture of India-Rubber Shurred Goods; Horace H. Day Jersey city, New Jersey, October 12.

The patentee says "The nature of my invention consists, in combining with rollers constructed with elastic surfaces, certain drums. and other appurtenances with elastic surfaces for stretching threads of india rubber to any given desired length, and the covering of said threads with india rubber cloth on both sides.

Claim." I do not intend to confine myself to any particular number of ruddles, combs, or friction rollers, intending to use as many such as may be necessary to do the work in the most advantageous way. Nor do I limit my claim to any particular contrivance by which to produce unequal speed between the friction and compressing rollers, using any such as will answer the purpose.

"I do not claim the invention of compressing or calender rollers, or the gearing with which they are driven; the same having been in common use in the manufacture of India-rubber, and for other purposes. I do not claim the rollers on which the cloth which is to cover the threads is beamed up or rolled, the same having been in common use in India-rubber and other factories. Nor do I claim the drums, or cog wheels, or bevel wheels, as new in themselves. I do not claim that part of the side frame in immediate contact with the table, and in which the compressing rollers revolve-such part being in common use in India-rubber and other factories. What I now do claim as my invention, and desire to secure by letters patent in the above described machine, is the combining with two compressing rollers, one or more friction drums or rollers, covered with suitable friction material, and combining with these the roller, together with the spool, an elastic band or apron to which the threads of India-rubber are attached. The whole being connected and working together in manner substantially as above set forth and made known."

20. For an improvement in the machine for Cutting Tallow and other articles; Zabria Ellis, Kensington, Philadelphia county, Pennsylvania, October 12.

"I am aware that a shaving or sliding cut has been given to the knife, by attaching each end to a connecting pendulous arm, in the manner of a parallel rule; and therefore I wish it to be understood that I do not claim this as my invention. But what I do claim as my invention, and desire to secure by letters patent, is the arrangement of the hand lever in combination with the knife, so arranged as to give a parallel sliding or shaving cut, and with the apparatus for feeding the straw, one arm of the hand lever constituting one of the parallel or pendulous arms of the knife, and another arm being provided with a segment mitre-wheel to operate the feeding apparatus as described."

23. For an improvement in the Bureau Bedstead; Henry W. Kingman, New York city, New York, October 12.

Claim.-"I do not claim to have invented any of the parts herein shown, when taken by themselves; but what I do claim, aud desire to secure by letters patent, is the making an article similar to a bureau or other piece of furniture, in the exterior appearance, and fitting the same to open in the parts b, g, h, i, and d, and legs 1 and 2, so as to attain the means of converting the article into a compact bedstead with great convenience, and at a moderate cost, with the several parts constructed and operating substantially as described.”

The piece of furniture resembling a bureau is divided into two parts, the back indicated in the claim by the letter b, and the front indicated by the letter g,-these are hinged to the pedestal of the bureau and fall back and front, the top of the bureau being attached to the back and constituting, when opened, the head of the bedstead.The part designated by letter i resembles a drawer, but conceals the front legs h, to support the front when let down. The legs for the back, are jointed to the back and to a rod 2, which is also jointed to the pedestal in such manner as to throw out the legs when the back is let down, and fold them when thrown up. And the part designated by the letter d, is that part of the bottom of the bed which covers

the pedestal when the bedstead is opened-it is jointed to the front and lays over on to the back, or vice versa; or it may be made in two, jointed to the pedestal, and laid over on to the front and back.

24. For an improvement in Lamps for burning volatile ingredients; Isaiah Jennings, New York city, New York, October 12.

In this lamp the ingredients are placed in a reservoir above the burner and connected with it by a pipe provided with a stop cock like gas burners. The horizontal part of the pipe, between the burner and stop cock, is filled with cotton cloth through which the volatile ingredients have to percolate when the stop cock is open. The horizontal part of the pipe ends in a bulb, from which rises the vertical part of the tube of the burner, and that is filled with a roll of cotton cloth.

The burner has the following peculiarity in its form-"The apertures which constitute the jets for the flame, open into a groove, on the outside; the use of which is to protect the issuing vapor from the action of the ascending current of air always produced by the heat from combustion; this ascending current, when it strikes the gas or vapor, immediately at its issue, has a disturbing influence on the flame, which is effectually corrected by the groove."

Claim. "Having thus fully described the nature of my improvements in the lamp for burning volatile ingredients, what I claim therein as new, and desire to secure by letters patent, is the manner of regulating the supply by the combined operation of the filling with cotton cloth, or other similar fibrous substance, in the parts designated, to gether with the packing of wire interposed, and the termination of the supply opening in a cylindrical stopper of straight wire immediately below the burner, as described. I claim, likewise, the employment of the groove in the burner, made in the manner and for the purpose set forth. I do not claim either of the individual parts of the packing embraced in the first claim, but limit my claim to their combination with each other, substantially as set forth."
