TURBINE-CASING.
Specification ,of Letters Patent.
Patented July 22, ran.
Application filed April 2, 1918. Serial No. 226,289.
and useful Improvements in Tunbine-Casings, of which the following is a specificatlon.
This invention relates to a casing for a fluid operated turbine; The main ect of the invention is to provide a turbine casing of simple construction, which may be made of pieces that are stamped out ofsheet metal, that can be readily assembled; into a casing unit.
The casing is of a type similar to the turbine casing shown in my co-pending application, Serial Number 224892, filed March 2c, 1918.
The turbine used in connection with the casing is intended to be operated by the exhaust I gases from an airplane engine and may be used to drive a centrifugal blower, as shown more; articularly in my copending application, erial Number 224356, 'filed March 14, 1918.
Another important object of the invention is to design a casing that can be produced in large quantities. A sheet metal casing, once the dies are made,;'can obviously be produced in large quantities.
Other objects and advantages 'will appear as the description proceeds.
Referring now to the drawings, in which similar reference characters indicate slmilar parts, Figure 1 is a side view, partly in secmodification.
The turbine casing consists of the main casing element 0, which is of the curved, an-
n'ular \shape as shown in Fig. 1 and is stamped out of sheet metal. Asemi-circular section P is formed integral with the main casing element C during the stamping process.
Associated I with said casing element 0,, there is an annular diaphragm D, stamped .out of sheet metal. Fonmed integral with the diaphragm D, is a semi-circular'portlon P; The semi-circular portions P and P have substantially the same radius and are adapted to'be fitted together to define-an inlet pipe I, when the parts 0 and D are fitted together, as shown in Fig. 1. The casing C and diaphragm .D together define an inlet chamber 1, which chamber is in comnfunication with the inlet pipe I.
Casing C and diaphragm D converge toward their inner ends and between said in ner ends is located a series of nozzles 2 of any desired construction. These nozzles direct the gases onto the buckets 3 of the turbine 4.
Auxiliary casing elements A andA, generally annular in shape, are provided and are stamped out of sheet metal. Each of the auxiliary elements A and .A' are formed with semi-circular portions Q and Q, of
the same radius, which portions are adapted to fit together to define an outlet pipe 0.
One of the auxiliary casing-elements such as 'A, is attached to the diaphragm D in any suitable way, such as by the rivets 5. The elements A and A are flanged-to fit against one another as at point 6.
The other of the auxiliary casing elements,
such as A, is provided with a flange 7, to
which flange is attached a back plate B,-
which plate extends inwardly from the flange 7 to a point at the inner edgeof the buckets 3, :bemg bent as shown to provide a curved path for, the gases escaping from the'buckets 3.
Diaphragm D, casing elements A and A and back plateB together define the outlet chamber 8, which chamber communicates directly with the outlet pipe 0.
-, The normal course of the gases is indicated by the arrows, the gases going into the inlet chamber 1 through the pipe P, passing through the buckets 3 into the outlet chamber 8 and thence out through the outlet pipe 0;
The parts P, P, Q, and Q may be pr0- vided withsuitable flang .turned over at right angles for the attacli ment of the necessary inlet and exhaust pipes.
The diaphragm D, it should be noted, is positioned between the inlet pipe I and the outlet pipe 0 at right angles thereto, to define the inlet and outlet chambers 1 and 8 respectively.
In order to control the speed of the turbine, the diaphragm D may be provided with means to by-pass the gases directly from the chamber 1 tothe chamber 8 without going through the turbine buckets 3. This by-pass may consist of a valve 9, seated on a valve seat 10, which valve seat may be pressed out of the diaphragm D and so made integral therewith. The valve 9 may be operated by any suitable means, such means being shown in my co-pending application, Serial Number 224894, filed March Fig. 1 shows inlet pipe I located at the side of the casing unit as a whole. It is obvious, however, that this inletpipe I can 10 be located at the back of the casing and such a modification is shown in Fig. 4.
In this case, the pipe I is pressed out and integral with the main casing element C; diaphragm D, in this case, playing no part in forming the inlet pipe. The diaphragm 'D is attached to the main casing element C at the point 11, by means of two annular flanges, one being formed on D and the other being formed on C. The diaphragm 30 D may, as in Fig. 1, carry a valve for bypassing the gases, which, however, it is not thought necessary to show. i
It should be noted that the elements for the casing may be readily stamped out of sheet metal. This is an important feature of the invention because it permits a pro duction of the casing unit in large quantities and does away with a lot of machining, brazing, welding and casting.
While I have illustrated two embodiments of my invention, it should be understood "that the invention may be carried out in other ways and, therefore, the disclosure should be considered in an illustrative sense and not in a limiting sense.
I cla1m: 1. In a turbine casing, a main casing element and a diaphragm, the two said parts being stamped out of sheet metal to define an inlet chamber and to form a pipe, parts 40 of said ipe being integral, respectlvely, with said main casing element and said diaphragm.
2. The combination as claimed in claim 1, the said diaphragm having a valve seat pressed out from it and integral therewith.
3. In a turbine casing, diaphragm, auxiliary casing elements associated therewith, the said parts being stamped out of sheet metal, said auxiliary casing elements having parts pressed therefrom to form a pipe, the parts of said pipe being integral, respec-- tively, with said auxiliary casing elements.
4:. The combination as claimed in claim 3, the said diaphragm having a valve seat pressed out from it and integral therewith.
5. The combination as claimed in claim 3, in combination with a back plate stamped out of sheet metal, the said diaphragm, auxiliary casing elements and back plate defining an exhaust chamber in communicarim with said pipe. I
6. A turbine casing comprising a main casing element and a diaphragm, parts of each being pressed out therefrom to form a 55 pipe, a back plate, auxiliary casing elements having parts pressed out therefrom to form a pipe, the said diaphragm being positioned between said pipes to define inlet and exhaust chambers.
7. The combination as claimed in claim 6, the parts being stamped out of sheet metal.
In testimony whereof Ialfix my signature.
