TURBINE FOR ORGANS 0R THE LIKE.

Application filed September 12, 1925. Serial No. 55,970.

To all whom t may concern.'

Be 1t known that` I, ANTOINE LAMON- TAGNE, subject of the King of Great B1 itain,

residing at Montreal, Province of Quebec, Canada, have invented certain ne w and useful Improvements in Turbines for Organs or the like; and I do hereby declare that the following is a full, clear, and eXact description of the invention, such as will enable others skilled in the art to 'which it appertains to make and use thesame.

The present invention pertains to a novel turbine for organs, although it may also be used in other installations where the functions of the device may be used.

In the present organ constructions, a high pressurei'or the pipes is obtained by mounting two or more rotors for the purpose of imparting the required. compression to the air driven thereby. In the operation of such a system, the air is driven from one rotor to the other, successively gaining in com-pression.

The object of the present invention is to eliminate the necessity of a plurality of rotors for creating the desired high `pressure. This object is accomplished by constructing the rotor casing in such a manner that the rotor itself is contained in two separate compartments. `One of these compartments receives the air which is compressed by half of the rotor to the maximum compression obtainable by the rotor. The partitions dividing the compartments are so ported that the compressed air driven by the rst half of the rotor is delivered to the second half Vby Which it is doubled in pressure and thus render suitable for high pressure purposes. Incidental to the reduction in the number of rotors necessary for high pressure, the fixed or anchorto. support a plurality of rotors are. materially reduced in number.

A further feature of the invention is the provision of a secondary outlet formed in the rotor casing in such a manner as to receive air under the first stage of compression by the'rotor. This airis suitable forl ordinary purpose, but the secondary outlet for supplying it desired, thus limiting the apparatus tothe productionof air under high pressure, or

using both outlets for two diiferent presmay be blocked if vwhich is concentric with following description and in the accompany-` ing drawings in which;

Figure 1 is a vertical section of the device; Figure 2 is a perspective view of the apv paratus;

Figure 3 is a perspective view of the separator disc surrounding the rotor;

Figure 4 1s a perspective view of the out- -let section of the turbine casing;

Figure 5 is a perspective view of the intermediate section of the turbine casing; and

Figure 6 is a perspective view of the inlet section of the turbine casing.

Reference to these views will novT be made by use of like characters which are employed to designate corresponding parts throughout.

The motor 1 for driving the rotor of the turbine is disposed within a motor boX 2 having air ducts 3 for the intake of air required by the rotor. The ducts are provided with doors 4 suitably mounted on hinges 5V so that they will open when a depression within the motor box occurs.

The shaft 6 of the motor carries a rotor 7 disposed within a casing consisting of three sections, the inlet section 8 being secured to the open slide of the motor box on ears 9 projecting from the latter. The wall 10 of this ysection which covers the open side of the motor box has an air port 11 establishing communication between the motor box and the rotor casing. An intermediate section 12 is secured to the inlet section 8, and a partition 13 is interposed between the two sections. This partition has a circular opening 14 within which the rotor turns. The partition is disposed in a plane parallel to a diameter of the rotor and lies lin the particular plane that bisects the rotor blades 15 radially with respect to the rotor unit. This partition furthermore has its lower corners cut oif as indicated by the numeral 16 in Figure 3, whereby the fluid driven from the rotor may flow from the inlet section 8 through the spaces formed by the cut-away corners in the manner described below.

The base 17 of the lintermediate section 12 has its lower corners cut away as at 18 in alinement with the cut off corners 16 of the partition 13. The corners 18 are also bridged by integral corner plates 19, forming a conduit in continuation with the spaces 16. The base 17 has an opening 20 the rotor. Finally,

The outlet section 22 is Secured to the intermediate section and is formed with an v outlet port 23 opposite the open corners 21.

' When it is desired to'use the rlhis section contains an internal dividing wall 24 which engages the base 17 of the section 12 in such a manner as to separate the opening 20 from the outlet 23. On the other side of the dividing wall, the outlet section has a second outlet port 25 which is closed by a cover plate 26 when not in use. second outlet 25 for the purpose stated below, the cover plate lis removed and a pipe 27 is secured over the outlet 25 as illustrated in dotted lines in Figure l.

The operation of the device is as follows: During the rotation of the otor, air is drawn through the ducts 3 in o the motor box 2, and thence through the inlet port 11 to the inlet section 8. l The airis acted upon by one half of the rotor, namely, the haltl lying at the inlet side ot the partition 13. This air is driven through the spaces iormed the cut-away corners 16, beneath the plates 19 and through the cut-away corners 18 of the intermediate section 12 to the outlet section 22. When the second outlet port 25 is closed, the air is drawn through the central opening 20 of the base 17 and to the half of the rotor disposed within the intermediate section. The air being previously under pressure received at the first halt' of the rotor'is now' increased to double this pressure by the second half of the rotor. Finally, the doubly compressed air passes through the open corners 21 of the base 1'7 and to the outlet 23. 'In this manner there is provided at the outlet 23 a supply o air of twice the pressure that can ordinarily be delivered by the rotor'. The apparatus therefore makes possible the production of a pressure which would ordinarily require two rotors of the size actually employed. Since such a high pressure is often required in the operation of organs, the two rotors ordinarily necessary in such cases may be replaced by a single rotor of the same type if the casing is constructed in the manner setforth.

For obtaining air at low pressure, that is, air at the rst stage of compression, the cover plate 26 is removed and a pipe 27 is v connected to the second outlet 25.-

While a specific embodiment of the invention has been illustrated and described, it is to be understood that various alterations in the details of construction may be made without departing from the spirit of the invention as indicated by the appended claims.

Having thus fully described the invention, what I claim as new and desire to protect vby Lettersfatent is 1.
