SASSENBERG AIR OR GAS DISTRIBUTOR 2 Sheets-Sheet 2 Filed Jan. 9, 1953 Patented Sept. 1 2, 1933' PATENT OFFICE m on GAS DISTRIBUTOR Jost Sassenberg, Cologne, Germany, assignor to Franz J. Kurth, Cologne-Dellbruck, Germany Application January 9, 1933, Serial-No. 650,916, and in Germany January 12, 1932 5 Claims. (01. 98-40) This invention relates to a method of and apparatus for introducing air into a room.
Distributors are known for supplying air into a room without the occurrence of draught, the 5 velocity'of the air introduced being entirely or partly suppressed immediately after its admission into the room. Under certain atmospheric conditions, however, if the air is supplied as is generally desirable in a draught-free manner it may not add to the comfort of the occupants of the room, for instance on sultry summer days, in vehicles or on board ship (for example in passenger cabins, saloons or ofices) and in tropical climates. In these cases air introduced with more or less high velocity may be found pleasing. One object of the invention is to provide means whereby it is possible to supply a current of air to a room either without any appreciable velocity, that is to say, free from draught, or with a velocity of flow, that is to say, with the desired draught. i
The invention is concerned with a method of introducing air into a room by causing an air current issuing from an air conduit to pass front of the outlet end of said conduit, said distributor being of the type comprising a number of throughway passages which increase in crosssectional area from their inlet to their outlet ends. According to the present invention, the velocity of the air entering the room can be varied by an angular adjustment of the air distributor and the outlet of the inlet conduit relatively to one another.
The invention also includes apparatus for the purpose set forth and comprising an air distributor oi the type described adapted to be arranged in front of the outlet end of an inlet conduit, wherein the air distributor is adjustable angularly relatively to the outlet end of the inlet conduit.
According to one feature of the invention a channel is provided connecting the inlet conduit and the air distributor and so arranged that all of the air issuing from the inlet conduit is directed into the air distributor in any position of the latter relatively to the inlet conduit.
According to another feature of the invention, the air inlet conduit communicates with the air distributor through a chamberformed by two spherical parts one rotatable within the other. One of these parts is connected to the inlet conduit and the other to the air distributor, thus permitting the inlet conduit and the air distributor to be angularly adjusted relative to one anthrough an air distributor which is located in other. I It will be appreciated that this chamber constitutes the channel aforesaid.
Preferably, one of the said spherical parts is fixed to an annular plate surrounding the outlet end of the inlet conduit while the other spherical 6i part carries the air distributor and has an outlet aperture which registers with the inlet aperture of the air distributor.
One embodiment of the invention will now be described with reference to the accompanying drawings on which:
Figure 1 shows the apparatus in vertical section with the air distributor arranged with its axis in alignment with that of the air inlet conduit,
' Figure 2 is a similar view showing the air distributor angularly displaced,
Figure 3 is a view of a modification of the air distributor drawn to a larger scale, and
Figure 4 is an underside View of the innermost conical partition of the construction shown in Figure 3.
The drawings are diagrammatic and like reference characters indicate like parts throughout.
As shown in Figures i and 2, the air distributor L comprises an annulus t and five funnel-like members t -tfi. arranged one within another to provide a number of throughway passages which increase in area from their inlet to their outlet ends. The annulus t is secured at k to a flange on a hollow spherical part J which is rotatably mounted in a hollow spherical socket formed by the spherical parts (i and e. A flange on the part c is bolted at i to a flange on the lower end of a conical tubular support 0, and a flange on the upper end of said support is bolted at h to an annular plate 11 which surrounds the inlet conduit a to which it is welded, soldered or otherwise secured. The spherical part d has at its upper end a flange which is bolted at g to the annular plate b. The spherical part I may be retained in the spherical parts d-e, so that it can be readily rotated therein by any convenient means,
and any suitable means maybe provided for holding the part I in different positions of adjustment relative to the parts 41 and e.
Since an air current issuing from a conduit flows out in a conical stream the periphery of which makes an angle of about 15 with the 1 bounding wall of the conduit, the air current issuing from the inlet conduit 41 flows out approximately in a conical stream bounded by the dotted lines W-O and p-q. The diameter of the air current as it enters the air distributor is o-q, no and the outlet aperture of the spherical part I and of the inlet aperture in the annulus t are approximately of the same diameter.
The annulus t carries on one side a bar s with a button m to enable the air-distributor L and the spherical part I to be rotated conveniently in any direction.
When the air distributor L occupies the position shown in Figure 1 with its axis in alignment with that of the inlet conduit 0, the air current as it enters the distributor is divided into a number of separate currents which issue from the air distributor in all directions with a reduced velocity of fiow. This position of the air distributor may be indicated by suitable marks on the spherical part ,1, and if desired also on the spherical part c.
If the air distributor L is displaced as shown in Figure 2, some of the throughway passages therein will be out of the path of the air current issuing from the inlet conduit a. In the example'shown, no air will flow through the passages between the annulus t and the funnel-like member t and between the funnel-like members t t on the left-hand side of the distributor as seen in Figure 2 because the inlets to those passages are outside the lateral bounding wall no of the air current. On the opposite side of the distributor, the corresponding throughway passages are likewise inoperative, because the lateral bounding wall p-q, of the air current meets the spherical part I at q. The air current after it meets the spherical part continues to flow for some distance in a path of the same curvature as said spherical part and thus sweeps past the inlets to the throughway passages aforesaid. The whole air current is thus constrained to pass through the funnel-like members t -t where it meets with little resistance and issues from the distributor with a perceptible velocity of flow with the result that the air entering the room is again perceived as a draught.
It may sometimes be desirable for the velocity of the flow of the air issuing from the air distributor to be perceptible at a distance of from three to four metres from the distributor. In such cases, it is preferable that the innermost funnellike member shall be of such a size that air can flow through this member without appreciable loss of velocity. In order, however, to ensure a draught-free distribution of air in the normal position of the air distributor, that is when its axis is in alignment with that of the air inlet conduit, there may be provided according to a further feature of the invention a valve controlling that funnel-like member, which valve is arranged to close said funnel-like member when the air distributor is in its normal position, but is automatically opened when the air distributor is displaced angularly. A convenient valve for this purpose is shown in'Figures 3 and 4. In this construction the innermost funnel-like member t of Figures 1 and 2 is omitted so that the larger funnel-like member t is now innermost. Mounted in the inner end of this funnel-like member is a disc it which is fixed to a spindle v .rotatable in bearings w in the wall of said funnellarly the disc it due to the uneven distribution of air pressure on its surface tilts into the position shown at u in Figure 3 and permits air to pass through the funnel-like member t The invention is not restricted to the precise constructional details described. For instance, the valve 21 instead of being controlled by the air current may be operated mechanically but automatically, when the air distributor is adjusted, by providing a suitable arrangement of links between the valve and the spherical part 11.
