In the accompaning enjgraving9,.Pia. 1, is a^ perspective view of á pükey einbodying: this invention, one of the rings being deUched?' i*' * , Fia. 2, is an axial, section, with botH^rings in place. ^ ^ ThehtibjAf is tapering ftm beJA epdsj alike, in the manner as shown, áhd is.ittsd’with rings» B.,B. which*ahí 'lapérihg-%^ttatoh the hub.'' ^ Fia. 1. The key, or set-screw, also forces the pulley or wheel “ out of thie *’ even when a good fit, so that when these fastenings are used, the incopvenient « driving fits are essential. With this device for attachment of the pulley to the shaft, the hubs may be bored a loose fit,' convenient to adjust and remove,'and yet, wben fastened be always concentric to the sbaft,^ . In easting, the slots in the pulley are cored and the tíngs are formed over a taper mandrel„mak^ ing them perfectly round and the proper taper for driving. ' The hubs of the pulleys are thefi turned.

Because the draught up the chimney draws in through the cracks of doors and windows or other crevasses and openings as muoh air as is withdrawn by the draught up the flue; and because this air enters the room in its natnral condition with all its elements and the proportions óf its ingredients unchanged, and is consequently fresh and invigorating; whereas, air from a furnace or from a close stove or. from steam pipes, or hot water pipes, is not only itself unfit to breathe, being in an abnormal condition, its ozom being destroyed by the hot surface over.wbich it has passed, being in fact cooked (either roasted by furnace or stove, ot boiled by steam pipes, or hot water pipeS) and áll its natural freshness and* invigorating qualities cooked out of it); but as such hot air presses upward through the^register or air-duct, }nto the room'it, prevents the entrance of all natural air through cracks or crevasses of doors and windowa; the pressure being outward throngh^these iristead of inward; ahd the inmatealsre confined entirely to this damaged, dull and unnatural atmospbere, wAloh has passed pver the hot iron surface. Most people; have very confused and * erroneous ..notious about heat, ilo. ti The hub'ai^bach end, from the extreme end to poittta i^r the urms, is splft, or slotted entirely through at two or ipore points^as shown, for the purpose of rendering the hub elastic, and enabling it-to be closed or contracted in Aize, by the driving on of the rings B^; B. 1 > : r. It will be seen' that the simple act of driving bn the rings 5* B. serves to force thq hub tightly, in all directions aUkq'ti) the shaft, and preserves the concentricity oft the pulley, or wheeL Fig; 3, shows pulley in position, also pulley-coupling attached, being the same in constrnction as pulley; its simplicity enabling one to disconnect’ the shaft, or remove the pulley with ease, in the shortest potÉible time. The* coupling is split from each end and nearly through; when the ringS are driven on an equal bearing over the entire surface is seoure4; tbe coupling is in one piece, On heavy shafting, where heavy work is required, a feather is inserted. It is well known, that in the use of the qommon ' Í • . taper-key, or the set screw for securing pulleys, &b. to shafts, that the inside of the hub, when fastened,, has but two points of bearing on the shaft, and those line bearings, and that neither the key nor set screw is admissible for hollow shafts, in consequence of tbeir liability to indent or collapse tbe shaft.

What is the best method of warming our houses ? Unquestionably radiation from an open fire. Do you say that this will not sufficiently warm your rooms ? Perhaps tbe open fires you have been used to having and seeing may not; but an open fire of proper shape and in the right position will. What this shape and position is will be soon ex- They call a coil of steam pipes a radiator whereas, it had better be called a conductor, as tbe greater part of its beat is given out by^conduotion to the air which comes in contact with it. People confound radiant heat with hot air; whereas, the heat which an open fire or the sun radiates is no more hot air thau it is hot water, or hot lead. Hot air moves slowly as water moves slowly. But radiant heat moves, as philosophers tell us, at the rate of 200,000 miles in a second, coming from the sun to the earth, a distance of nearly 95,000,000 miles, in about 8 minutes. We generally see that hot air moves upward, and without stopping to reason or analyze we conclude that the natural course of hcctt is upward * whereas, pure or radiant heat moves downward (as from the sun) as easily as upward. It passes through the air without affecting it, or being affected by it. A ray of heat, in its inconceivably rapid flight, neither heats the air nor can it be turned aside oven by a bnrricane. Open tbe mouth of a great furnace, when in full blast, and though, there is a powerful current of air setting in through the opening, yet the rays of heat moving in the opposite direction, and directly against this current of air, will soon drive you baok. But it is not only true that hot air moVei upward (because it is lighter than cooler air) and hence tends to get away from us as soon as possible (ayerv benevoleat arrangement of Providence); but it is also true that a large part of the radiant heat from our open fires also goes upward.
