In a few weeks we expect to be able to present engravings of a pneumatic telegraph, i invented by J. S. Richardson, of Boston, which presents features of a new and important character. This kind of telegraph is composed of a tube, which,by exhausting the air from it by a steam engine working a huge air pump, is intended to send packages from one place to another through it with great velocity. The idea of sending packages in this ' manner from one place to another is not new, f many attempts have been made to carry it I out, some of which we have witnessed. Me-. chanical difficulties, however, have prevented the success of suth a desirable mode of ex-" pressing parcels, and these it is believed have [ been overcome by Mr. Richardson. His at-, mospheric tube telegraph and railway is ! very ingenious, and in a tube one mile long, it has operated successfully for some time. ? We will present a more full description of the ? invention when we illustrate it. A joint ' stock company is about to be formed for a , line of this telegraph, between this city and Boston. List of Patent Claims Reported Officially for the Scientific American Issued from the United States Patent Office for THH TBEK ENDING MARCH 29, 1853. LUBRICATING OILS—By Luther Atwood, of Boston, Mass. : I claim the manufacture or combination of paranapthaline and fixed oils derived from coal tar, and boiling from 450 to 675 degrees, Fahr., as produced by the process, as described, the said new manufacture being highly useful as a lubricating composition, either alone or combined with oils or fatty matter, as set forth. Also the combination of this product, so made with concrete, or thick fatty matter, or oils, for the purpose of liquifying them, or rendering them more mobile, or imparting to them lubricating qualities, as specified. WINNOWERS OF GRAIN—By S. Briggs J. Ct. Talbot, of Sloansville, N. Y. : We claim causing the upper sieve or riddle to vibrate at a greater speed than the screens, as set forth. BREAKING HEMP—By Lewis W. Colver, of Louis ville, Ky. : I claim the combination of the oscillating beaters, and the spring bars placed above and below the beaters, so that the recoil of the springs after the beater leaves the bars, shall shake out the hemp and clear it of its woody portions, as described. HOT-AIR FURNACES—By Wm. Enuis, of New York .City: I claim the employment) of an inverted cone within a drum or cylinder, in whose side the taper end of said cone is inserted and allowed to communicate with the surroundiDg atmosphere for the purpose of creating an atmospheric reversing draft to cool the direct heated current from the fire ; the said cylinder communicating with the fire chamber and ash pit, as described. ELECTRIC TELEGRAPHS—By Moses G. Farmer, of Salem, Mass. : I claim the method,as described, of bringing any number of telegraphic signalizing and recording instruments into successive electric connection with the common communicating wire; meaning, more particularly, to claim the combination of the writing and working, or primary and secondary circuits, the electro-magnets and movable armatures of the primary circuit, the local magnets, and their movable armatures and pallets, or equivalents therefor, and local battery and battery connections of each terminus,and connections leading to the armatures of the local magnet, the escapement wheels and wheels U and Z on the arbor of each, the two series of springs of said wheels U and Z, and branch connections, and the branch connections of the main writing circuit at its two termini, the whole being connected and made to operate together, as described. PENDULUM BALANOJI—By Benj. Fenn, of Hartford, Ohio : I claim a machine for ascertaining, instantly, the weight of bodies by means of a scale, dish or plate, supported by pivots upon a heavy weighted semicircular frame, or its equivalent, in the manner of a pendulum, and operated by catches, 1 as described. SEED PLANTERS—By Isaac H. Garretson, of Clay, Iowa : I claim planting corn in check rows, by the planting sides, worked on the cross bar by hand, in the manner set forth. KNITTING MACHINES—By John Maxwell, of Gales-ville, N. Y. : I claim the construction of the locking apparatus, fby placing standards upon the back ends of the half-jacks, to carry springs, which regulate the pressure of the bar upon the jacks, in combination with an apparatus for raising said locking bar, the whole constructed and arranged for the purpose set forth. PAGING BOUND BOOKS—By Thomas McAdams, of Boston, Mass. Ante-dated Sept 29, 1852 : I claim the employment of a square, rotating shaft, as a bed for the odd numbers, and the shaft D, as a bed for the even numbers of the types, in combination with the tongue, as a platen to both sets of types, the same being operated by the treadle, ratchets, and pawls, so as to enable the operator to print the odd and even numbers of the alternate pages of a bound book, by a single movement of the treadle, as described. SPIKE MACHINES—By James H. Swett, of Boston, Mass. : I claim skewing the shafts or axes of rotary-pointing dies, so that they shall stand oblique to "ach other, and bevelling off the faces of the dies to the same, or about the same angle at which the shafts stand to or cross each other, for the purpose of forming a close-fitting space in front of the dies, or where the blank is fed in, and spreading the dies in rear or behind, where the spike is pointed, so as to release it and allow the nippers to take the spike from the pointing dies, without injury to the spike, as described. VERTICAL PIANOS—By George Traeyser, of Cincinnati, Ohio : I claim the c onstruction, as described, of a vertical piano, having the tuning pins placed below the lower edge of the sounding board, for the objects explained. SEWING MACHINES —By Thomas C. Thompson, of Ithaca, N. Y. : I claim, first, the magnetic shuttle and race, one or both, for the purpose of keeping the shuttle in perfect contact with the face of the shuttle race, without the uee of springs, or any other device, and thereby ensuring the securing of every stitch, as described. Also, the curved and hinged cap, in combination with the shuttle, to confine the cop in the shuttle, as set forth. Also, the use of a cop, without a spindle or spooler, in combination with a shuttle, or its equivalent, when the thread is drawn from the inside of the cop, by which means 1 retain a uniform draught on the cop thread as it is drawn or paid out from the shuttle, as described. WIRE FENCES—By Matthew Walker, Matthew Walker, Jr , D. S Walker, of Philadelphia, Pa. : We claim the arrangement of the hooks within the mortises, so that the parts of the hook shall be sustained and kept from, spreading by the mortise, and a strain upon the wires tend to steady the posts, as described. EE-ISSCI. SCREW BLANKS—By Thomas J. Sloan, of New York City. Patented Feb 2D, 1851 : I claim thei lifters, which select and lift the blanks, etc., from i the: hopper, substantially as specified, in combination with ways or conductors, or the equivalents thereof, as specified, into or on to which the blanks, etc., are transferred. Also, giving to the lifters or to the inclined ways, or their equivalents, a lateral moti on, in combination with a stop or detector, as specified,for the purpose of arresting the operation of the lifters until a further supply is required. Also, the sliding carrier, with its recess, for receiving and holding the screw blanks, as specified, in combination with the spring fingers, for taking the screw blanks from the carrier, and presenting them to the jaws, as specified.
