Abstract: 24,356. Wallace, C. W. Nov. 10. Air, cooling, heating, and moistening; air, drawing-off and supplying, methods of.-In a system of heating, cooling, or ventilating rooms, passages, halls, and the like, the humidity of the air in the rooms or the like is regulated by the employment of special forms of radiators, heating or cooling pipes, and arrangements thereof. Two forms of radiators are shown in Figs. 1 and 2 and Figs. 18 and 19, respectively. Figs. 22 and 24 show one wall of a hall or other apartment fitted with heating or cooling and ventilating appliances. The other Figures show details of constructions. The radiators are formed of metal tubes b and porous tubes a arranged alternately. The metal tubes b may be provided with ribs d' having extension pieces d<3>. Wire netting or a wire frame may be inserted between the pieces d<3>. Each porous tube, as shown in Fig. 3, has a central tube h, which is open at its upper end and connected at its lower end to a water-outlet pipe p', Fig. 1, by a passage p located in a bottom piece shown in Fig. 11. This Figure also shows the passage o by which the annular space between the inner tube h and the outer porous tube is connected to the water-supply pipe o<2>, Fig. 6, passing through the bottom piece. The outer porous tubes are connected to the bottom pieces by rims or joint connections r, several forms of which are shown in Figs. 14, 15, and 16. Filling s<3> of plaster of Paris, leather, india-rubber, or the like, or a compression spring s', may be placed between the tube a and the rim r, which then receives a screw cap or ring s. The rim r may be made separate from, or integral with, the bottom piece. The porous pipes a, Fig. 9, may have interior linings of perforated or galvanized metal to prevent a deposit from forming on the pipes. The pipes may also be provided with exterior wirework a<9> to diminish the breakage. At the end of the radiator, a special pipe i is provided to regulate the level of the water in the porous tubes. This pipe, shown in detail in Fig. 7, is provided with an inner tube i<3> which passes through a stuffing-gland i<4> and is open at the top. The height of the top of the inner tube is regulated by a rod i' which passes through a cap on the top of the tube i. The tube i is provided with a bottom piece q<1>, Fig. 6, by which it communicates with the flow and return tubes o', p'. The metal tubes b communicate with a pipej which is secured to the framework of the radiator at opposite ends by left-hand threaded nuts j<2> and right-hand threaded nuts j<3>. By loosening these nuts, the pipes b may be inclined as shown in Fig. 8. A top piece f<1>, connected by rods f<2 >or the like to the top f, is adapted to fit over the top connecting- pipe of the pipes b so as to hold the pipes in an inclined position. Figs. 31 and 32 show alternative forms of pipe connections p', o<2>. The inner tubes o', p' extend the length of the radiator, the outer tubes o<8>, p<8> serving to space the bottom pieces apart. The inner tubes, which have holes o<9>, p<9> for water communication with the bottom pieces, end in shoulders so that they may be clamped in position by nuts. As shown in Fig. 32, the pipes o<2>, p<2> are adapted to be fitted in short lengths between the bottom pieces. The pipe o<6> is formed of two parts, one part o<7> being connected to the other through a screwed cap o<10> engaging the nippled end of the part o<7>. The last section of piping has its ends screwed in the same direction, instead of in opposite directions as in the case of the intermediate sections. In the radiator shown in Figs. 18 and 19, porous tubes a are connected through T-pieces r<1> to quadrant-shaped tubes w which are united by flanges v. The tubes may be lined with a metal casing and non-conducting composition. For ventilating a room or hall, a radiator A and ventilating-box C, Fig. 22, are arranged in front of an air entrance. The air inlet is regulated by the trellis shutter shown in Fig. 29. The trellis is connected by pairs of pins n<5> to side supports n<1>, n'. The upper pair of pins n<5> connect the trellis to blocks which slide in grooves in the side supports. The tops of the ventilating-box C and radiator A are also provided with hit-and-miss gratings to regulate the admission of hot air to the room. Compound porous heating-pipes m are supported in the upper part of the hall above a trough m' which catches any drip water. The pipes m have inner perforated pipes m<1> through which the water supply passes. The compound tube m is supported above the trough by a crosspiece fixed to the supporting-bracket m<3>. In the arrangement shown in Fig. 24, a radiator B which may have inclined tubes is arranged in front of the air outlet controlled by a trellis shutter n. The room may be cooled by passing the air on its way to the ventilating-box C over cooling-pipes arranged in the basement. The Provisional Specification also describes a system of ventilating underground passages and spaces by placing hotwater or cold - water radiators of the above construction in the upcast and downcast air flues. When a warehouse or the like is adjacent to a set of boilers used at intervals, the apparatus described above may be provided with extensions of the porous pipes, which may be shut off when not required.
