in the mechanism employed to impart the desired motion to the gum box in relation to the lifters, to counterbalance the conveyor, to crease: fold, and press the en velopes, and to discharge them from the machine when finished. George H. Reay, of New York city, is the inve�tpr of thi�l machine. The patent has bean assigned in full to L. Negbaur, No. 5 Spruce street, New York. Ring Spinning Frame.-In most if not all ring spinning frames heretofore constructed, the rings ha ve been fitted snugly
more » ... een fitted snugly into openings provided for them in the ring rail, without any provision for adjusting them in the said rail. This rail is held in place by lifting rods which work up and down in stationary guides provided for them in the frame, and as these rods and guides wear, the rings become eccentric to the spindles, lind cause great irregullnity in the draft of the yarns in every revolution of the travelers and spindles, and make imperfect work_ The object of this invention is to provide for the adjustment of the several rings in the rail separately, to set them concentric with their respective spindles; and to this end it consists in making the openings provided in the ring rail for the reception of the rings larger than the ederiors of the portions of the rings which are received within them, and in the employment ·of arlj usting screws screwing into the rllil from the inner and outer sides thereof, and into the said holes to adjust and hold the said rings therein. Weloome Jenckes, of Manchester, N. H., is the inventor of this improvement. Leather-splitting Machinc,-This invention consists, first, in the employment for adjustivg the gage roller at the proper distance from the plane of the edge of the splitting knife according to the thickness to which the skin is to be reduced, of a pair of eccen trics or cams attached to the same shaft, and arranged to act one upon each of the journal ·boxes of the said roller, wheraby the uniform adjustment of both ends of the said roller is insured, and the difficulty .of adjusting the said roller correctly by separate adjust ments, such as the screws oommonly employed, at each end, is overcome. It also consists in mflking the standards or housings which contain the journal boxes of the gage roller adjustable, to bring the said 1"oller more or less on the edge of the splitting knife, whereby the knife is enabled to be better secured �gai ' nst8PFiflgiQg or accidental displacement, by ob viating the necessity of adjusting it. Horace Wing, of Buffalo, N. Y., is the inventor of this improve ment. Bone-black Oven.-This invention consists in the arrangement within a rotating circular retort, of a continuous flange running fpirally around its inner surface from end to end, or along any portion of its length, whereby a gradual and regular movement of the bone-black from one;end to the other is obtained, by the rotary motion of the retort about its axis without giving it any inclination from a horizontal position. It also consists in the arrangement of a drying retort or cylinder in the same oven or casing with, and in sucb relation to and connection with the revivifying retort, that it may be heated by the waste heat from the same fire by which the latter retort is he�ted, for the purpose of drying the wa.shed bone black preparatory to re burning, and that the dried bone-black may be delivered continuously from it to the re-burning or revivifying retort. It further con sists in a novel mode of connecting the revolving, revivifying retort with the coolers or other recepta cles into which the revivified bone-black is dis charged. Gustavus Finken, of New York city, is the inventor of tbis apparatus. Houe Pitchfork.-This invention relates to a new and improved horse pitchfork, such as is used for elevating by means of a horse or other draught ani mal, hay and grain into mows. The invention con sists in the employment of two pairs of hooks pro vided with arms, those of each pair crossing each other and fitted on a rod, the ends of the arms of each pair of hooks being connected by a crossbar, and the latter having a rope attached to or connected with them, in such a manner that when the loaded fork is raised by means of the rope aforesaid, the hooks will be made to gra�p and firmly hold its load, and the hooks, by. a fimple contrivance readily re leased at any time, to discharge the load. Silas L Gates, of Verona, N. Y., is the inventor of this im proved pitchfork. Tailor's Shears.-This in vention consists in h�ng the lower blade of tailors' shears formed with a recess or shoulder, in such a manner that the cutting edge of said blade can be brought down in lil;le, or nearly so, with the pivot connecting the two blades, without unduly weakening said blade, and that by this construction of the shears a draw cut is produced, enabling the operator to work the shears with the greatest ease, and to have the full b6Defi t of the cut ting edge from heel to point. Herm�n Wendt, of New York city, is the inventor of this improvement. For further information-address Henry Seymour, 32 B 'ekman street, New York. Rocket.-This invention is more especially designed for signal rockets for military and other operations. It consists, first, in the application to or within a rocket, of a roman candle, for the purpose of dis charging stars of the same or different colors, one after the other, and thereby enabling a greater variety of and more distinct signals to be produced. It con sists,secondly,in making the stars of the roman candle with cavities in their upper ends, containing charges of gunpowder or other suitable explosive substance, for the purpose of driving out the balls from the case and igniting them at the same time. It consists, ' thirdly, in so combining a balloon with a rocket as to make it keep suspended for a time, or retard the descent of a roman candle or otheriirework discharged from the rocket, for the purpose of making a signal, whereby such firework is rendered visible for a longer period, and the signal enabled to be better understood than if it descended quickly. It consists, fourthly, in the novel construction and arrangement of a series of di vergent spiral passages in the bottom of a rocket, for the purpose of obtaining its rotary motion by the escape of the gases eliminated in the combustion
