Application 516a December 29, 1897. Serial no. eesaso. (No model.)
To all whom it may concern:
Be it known that I, RICHARD GoLL, manufacturer, residing at Frankfo'rt-on-the-Main,
. in the Kingdom of Prussia, German Empire,
have invented new and useful Improvements in Apparatus for Equalizing Air-Currents, (patented in Germany, No. 84,471, dated July 29, 1893; in France, No. 248,66l,'dated July 4, 1893; in Austria, No. 46/470, dated January 18, 1896; in Hungary, No. 5,086, dated January 19, 1896; in Switzerland, No. 12,713, dated January 18, 1896, and in Italy, No.
i 31/ 10,680, dated March 3, 1896,) of which the following is a specification.
The object ofmy invention is to obviate the drawbacks inherent to the actual systems of distributing the air and to regulate its current when used for the ventilation of rooms or the supply of furnaces and the like. The air has always the tendency to go from its entrance into a room or chamber on the short est way to the point where an opening for the escape of it is provided, especially if the air enters under pressure or escapes by suction. Even in cases wherein a conduit for the admission or the escape of the air is divided into different branches leading to different polnts of one room, this inconvenience is not sufficiently diminished, because the openings of the branch pipes or conduits placed in the count of their shortness and smaller friction convey more air than the openings at more bent at different places. In this instance the maximum current will follow a line which approaches a straight line as nearly as the obstacles put in the way of it will allow. The
supply of the air to the points distant of this line will be smaller. This is true for the points situated in the immediate neighborhood of the grate, where an equal supply of air to all points in the fuel is wanted. I propose to remedy this by shaping the conduits in connection with the distant points of a room in a waythat their lengths are equal and attain this by curving or otherwise bending the conduits leading to thenearer points. In cases where the stream of air is not divided into different films or branches 1 provide partition-walls or the like, forming conduits of equal length between themselves. This is especially the case if my invention is applied to fire-grates. As the air has the tendency to stream in a straight line from the door of the ash-pit to the back part of the grate and the edge of the fire-bridge and there from obliquely upward to foot of the chimney, I lengthen the ways of the air passing at the back part of the grate, and thereby attain a perfectly equalized draft in the plane of combustion.
In order to show the manner in which I carry my invention out, I have affixed drawings.
Figure 1 shows the ventilation of a room; Fig. 2, aconstruction of a grate and flues under a boiler; Fig. 3, another construction for the same purpose.
Fig. 1 is a plan of the ceiling of a room, wherein conduits for the escape of the air are provided. H is the chimney or main channel leading the spent air into the open air. a b c d are openings in the ceiling connected by pipes A B O D with the channel H, the pipes B A D being curved to attain exactly or approximately the length of the pipe 0.
In Fig. 2, A represents the grate; B,the entrance-opening for the combustion-air in the ash-pit; b, the fire-bridge mand 'n, partitionwalls built to divide and conduct the combustion-gases. The current of the combustion-gases is split into three branches q r 8, following the arrows 1 2 3. Without the partition-walls the suction exercised by the chim ney would prove strongest for the part 8 of the gases, and therefore the speed of these gases would be the greatest and their quanheld closedand the air admitted by a conduit' Herethe current of the air is splitin O. the same manner, and the paths leading from the mouth 0 of the conduit to the difierent parts of the grate are rendered approximately equal in length.
Ihe system of ventilation shown in Fig.1 may be especially advantageously applied it the conduits consist of rubber tubes allowing to displace the entrance or discharge openings.
It will be seen that thepassage which leads from the part of the room or chamber farthest from the outlet, as C, Fig. 1, or q, Fig. 2, is straight, and that the extent of bend of the other passages increases with the nearness to.
the outlet of the inlet ends of said passages, thereby equalizing the lengths of the passages. r
Now what I claim, and desire to secure by 20 LettersPatent, is the following:
The combination with a chamber having a suitable outlet through which air is to be passed from the chamber, of a plurality of passages from points at diiferent distances 25 I
