Description: |
| Abstract:
In the manufacture of traction engines many portions, like the king-post, the engine, etc. must be attached to the boiler shell and it has heretofore been customary to provide the boiler shell with threaded openings into which threaded clamping bolts are passed, said clamping bolts passing through castings forming part of the members mentioned. with such a construction it is difficult, after a time, to maintain steam tight joints, and recently the Canadian Government has passed an act condemning such construction unless reinforcing plates be arranged inside of the boiler shell at the points of attachment. Such a reinforcement is objectionable for many reasons, and the object of my present invention is to produce a construction by means of which castings, such as the king-post, journal bearings, engine, etc. may be attached to the boiler shell by removable bolts in such manner that a perfectly steam tight boiler shell may be maintained and in such manner that the expansion and contraction of the shell will not injuriously affect the said connections.
Claim:
In a traction engine, the combination with the boiler shell, of a pair of circumferentially arranged angles permanently connected to said shell, and a king-post member detachably secured to the vertical arms of both said angles. |
