Abstract
Abstract A method of mounting a structural component of a dynamoelectric machine to a stationary member thereof. A set of beams is mounted to the stationary member, and the beams are positioned within receiving means provided therefor in the structural component. Molten metal is introduced into the receiving means for mounting engagement between the beams and the receiving means, and the metal solidifies thereby forming means for holding the beams and the receiving means in mounting engagement.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
93 words
A method of mounting a structural component of a dynamoelectric machine to a stationary member thereof comprising the steps of: a. mounting a set of beams to the stationary member; b. positioning end portions of the beams within receiving means provided therefor in the structural component; c. introducing molten metal into the receiving means for mounting engagement between the beam end portions and at least a portion of the receiving means; and d. solidifying the metal thereby forming means for holding the beam end portions and the receiving means portions in mounting engagement.
Claim 2
Independent Claim
93 words
A method of mounting a structural component of a dynamoelectric machine to a stationary member thereof comprising the steps of: a. mounting a set of beams to the stationary member; b. positioning end portions of the beams within receiving means provided therefor in the structural component; c. introducing molten metal into the receiving means for mounting engagement between the beam end portions and at least a portion of the receiving means; and d. solidifying the metal thereby forming means for holding the beam end portions and the receiving means portions in mounting engagement.
Claim 3
Dependent Claim
34 words
The method as set forth in claim 1, wherein the solidifying step includes shrinking of the metal upon solidification thereof for gripping engagement with both the beam end portions and the receiving means portions.
Claim 4
Dependent Claim
25 words
The method as set forth in claim 1, comprising the intermediate step of closing an end of the receiving means prior to the introducing step.
Claim 5
Dependent Claim
29 words
The method as set forth in claim 3, wherein the intermediate step further comprises urging heat resistant means into engagement with the structural component about the receiving means therein.
Claim 6
Dependent Claim
38 words
The method as set forth in claim 4, wherein the positioning step comprises spacing the beam end portions from the end of the receiving means for preventing engagement of the beam end portions with the heat resistant means.
Claim 7
Dependent Claim
26 words
The method as set forth in claim 1, wherein the positioning step comprises spacing the beam end portions from confronting side walls of the receiving means.
Claim 8
Dependent Claim
40 words
The method as set forth in claim 1, comprising the preliminary step of providing means on the beam end portions for engagement with the metal upon the solidifying thereof to prevent displacing the beam end portions from the receiving means.
Claim 9
Dependent Claim
28 words
The method as set forth in claim 7, wherein the engagement means includes at least one aperture extending through at least a portion of the beam end portions.
Claim 10
Dependent Claim
24 words
The method as set forth in claim 7, wherein the engagement means include tab means integral with the beam end portions and extending therefrom.
Claim 11
Dependent Claim
26 words
The method as set forth in claim 1, wherein the receiving means includes sockets having side walls disposed in spaced relation with the beam end portions.
Claim 12
Dependent Claim
37 words
The method as set forth in claim 10, wherein the receiving means portions include means integral with the side walls and extending away therefrom into the sockets for gripping engagement with the metal upon the solidifying thereof.
Claim 13
Dependent Claim
36 words
The method as sEt forth in claim 11, wherein the gripping means includes a stud having one end integrally connecting with the side wall and having a cross-member on a free end thereof within the socket.
Claim 14
Dependent Claim
41 words
The method as set forth in claim 11, wherein the gripping means includes at least one flange means having one end integrally connecting with the side wall and having a free end disposed within the socket spaced from the side walls.
Claim 15
Dependent Claim
30 words
The method as set forth in claim 1, wherein the mounting step further comprises staking the beams into displacement preventing engagement with groove means provided therefor in the stationary member.
Claim 16
Dependent Claim
57 words
The method as set forth in claim 1, wherein the introducing step further comprises pouring the molten metal into the receiving means between gaps formed between the beam end portions and the receiving means thereby establishing metal plugs upon the solidifying of the molten metal in mounting engagement between the beam end portions and receiving means portions.
Claim 17
Dependent Claim
40 words
The method as set forth in claim 1, comprising the preliminary step of forming means in at least the end portions of the beams for accommodating the passage therethrough of molten metal upon the introduction thereof into the receiving means.
Claim 18
Dependent Claim
55 words
The method as set forth in claim 1, wherein the beams are generally U-shaped in cross-section, and wherein the introducing step further comprises pouring the molten metal into the U-shaped beams adjacent the point of entry thereof into the receiving means and flowing the molten metal downwardly within the U-shaped beams into the receiving means.
Claim 19
Dependent Claim
25 words
The method as set forth in claim 1, comprising the additional step of securing another structural component to the opposite end portions of the beams.
Claim 20
Dependent Claim
23 words
The method as set forth in claim 1, wherein the structural component and stationary member respectively include an end frame and a stator.
Claim 21
Dependent Claim
23 words
The method as set forth in claim 1, wherein one end of the receiving means is closed for holding the molten metal therein.
