Book Description
Excerpt from Journal of the Franklin Institute of the State of Pennsylvania, for the Promotion of the Mechanic Arts, Vol. 44: Devoted to Mechanical and Physical Science, Civil Engineering, the Arts and Manufacture This table shows that, of the three systems of draft indicated, according to the hypotheses, and with the same numerical data nearly approximating to the circumstances which may present themselves in practice, that in which the air drawn out is heated on the level Of each story, will cause, for the same expenditure of heat, a rather greater velocity for the basement, about the same for the first story, and a little less for the second story, than that in which the draft is pro duced from below. As to the system in which the furnace is placed above the stories to be ventilated, it will cause, as was to be expected, velocities in all the cases rather less than the other two systems. The system of draft from the level appears therefore to be the most advantageous of the three: its superiority and that Of the draft from below over that of the draft from above is to be entirely attributed to the fact that in the two first systems, the heights Of the discharge chimneys permit more advantage to be taken Of the specific levity given to the air: but it must not be forgotten that, as the walls Of the chimney cool the air which passes through them, the velocity may thus be diminished and the advantage of this arrangement somewhat reduced. However this may be, it appears to me to result from this discussion that the system of draft from the level ought to be preferred to the two other systems; its introduction presents no difficulties Of construe tion, and according to the examination Of the proposals for the offices Of the Northern Railroad, it appears to be both more economical in cost Of construction and of daily expenditure: the great height Of the chimneys must also give great stability to the effects.

Excerpt from Journal of the Franklin Institute of the State of Pennsylvania for the Promotion of the Mechanic Arts, Vol. 68: Devoted to Mechanical and Physical Science, Civil Engineering, the Arts and Manufactures, and the Recording of American and Other Patent Inventions; July, 1859 The principle upon which t e apparatus is based is, that as the pres. Sure is equal upon all the interior surface of a steam boiler, and con sequently as each unit of surface sustains the same pressure, if the steam is taken from the boiler into the apparatus by a larger orifice than that through which it is returned, the force of entry of the steam will be in greater proportion to the dimensions of the two ori fices; or, in other words, steam brought from a boiler through a pipe of a given diameter, can easily be forced into the boiler again through the other end of the pipe, provided it have a much smaller aperture. In the machine in question, the entering orifice bears but a very small proportion to that of the supply pipe, because it is necessary to allow for the loss of force occasioned by the action of the water upon the steam. In the above cut the apparatus is represented in a horizontal dispo. Aition, whereas it is now made vertical, but the only difference in the arrangement of the parts is the curving downwards of the two water pipes G and K.
