In locomotive fire-boxes and in the combustion chamber of marine boilers, there are two flat or slightly curved surfaces that must be stayed together. These are riveted by short screw stay bclta. The bolts shown in Figs. 34 and 35 are screwed in place, and the ends riveted over. I just got finished with a video showing all of the staybolts required on the boiler of a steam loco. For what reason are these necessary? It seems it would be easier just to use a boiler like in a furnace or factory. Why have all of thhose bolts anyhow? Any answers would be appreciated. Charles Th The Shay steam locomotive was the most well-known and widely used of the geared designs to operate in the country (the others being the Climax and Heisler, which followed in the footsteps of the Shay but were not quite as successful) with nearly 3,000 constructed from 1880 through nearly the mid-20 century.

When it comes to working on a Living Legend, it’s the details that matter. In this month’s Steam Update, UP's Steam Team talks about the tooling made while working on locomotive No. 844 and also shows the process of fabricating a stay bolt from beginning to end. This spurred an interest in reviving an operating steam locomotive and thus train rides for the public. From approximately 1985 - 2000, the locomotive was used sparingly in a yearly railroad celebration. This engine is coal fired. The engine was re-flued in 1995 with new crown stay bolts added at that time.
Stay bolts on an antique boiler, part of a steam locomotive engine. Save Comp Union Pacific's steam team finally is getting down to the bones of UP No. 4014, the 'Big Boy.' The locomotive's big steel front engine bed has been exposed and has a glossy new coat of black paint.
The steam locomotive owner and/or operator shall tap each bolt with a hammer and determine broken bolts from the sound of the vibration of the sheet. Whenever staybolts are tested while the boiler is not under pressure, such as during the 31-service-day inspection, the stay bolt test must be made with all the water drained from the boiler.' There was a leak at one of the several hundred stay-bolts in the firebox. Stay-bolt replacement is a routine steam locomotive maintenance procedure, so we weren’t too concerned. Alas, when the leaking stay-bolt was removed, we found a crack on the inside (water side) of the firebox at the bolt hole. Although steam locomotives are no longer used by the major railroad companies for transport, many remain in use on museum railroads for the public, while others are undergoing restoration. The following brief description of the steam locomotive boiler will acquaint inspectors with its construction and summarize the inspection procedure.
Locomotive boilers are made entirely of steel, except stay-bolts and stays, which are of iron. The crown sheet is supported by what are called radial stays, reaching from the crown sheet to the exterior wrapper sheet. There are three common designs of fireboxes in general use. Union Pacific Steam Club Update No. 2 - Feb. 6, 2019. Big news from Cheyenne: Union Pacific's steam locomotive No. 4014, the Big Boy, passed its hydrostatic test... s.Click on the pic for the video of them hammer testing the stay bolts at operating pressure. The hydro was at 375 psi for 20 min if I remember correctly.
A locomotive boiler is a device which is used to create steam from water by using heat energy. It is a horizontal drum axis, multi-tubular, natural circulation, artificial draft, forced circulation, mobile, medium pressure, solid fuel fired fire tube boiler that has an internal fire furnace. Now that the firebox sheets have been replaced, the primary focus is now on the installation of the staybolts. Approximately 300 staybolts were cut out in the areas where the new firebox sheets were applied. The firebox sheets are supported by many stay bolts. The boiler shell (wrapper sheet) around the firebox has a water space between the inner and outer sheets.
To add to this: Many stay bolts are drilled with a hole through their length. Reason? If the stay breaks, steam and vapor will escape from the hole leting you know it needs to be replaced. If a lot of drilled stays are leaking in the same area, that shows possible boiler plate damage and warping. The ex China Rail and Jitong Railway QJ 2-10-2 No. 7081 is due for something called a 15 year inspection. I think as from what has been said from the Central States Steam Preservation Association facebook page is that its cab needs to come off for inspection of all the flexible stay bolts before it can run again.
Stay bolts in a steam boiler should support the plate completely. They should allow free water circulation and they should allow room for boiler inspection. The principal types are the solid screw stay bolt and the hollow bolt. The solid screw stay bolt is completely threaded and is screwed into the boiler plates so both ends extend inch. The Pennsylvania Railroad's class S2 was a steam turbine locomotive designed and built in a collaborative effort by Baldwin Locomotive Works and Westinghouse Electric & Manufacturing Company, as an attempt to prolong the dominance of the steam locomotive by adapting technology that had been widely accepted in the marine industry.One was built, #6200, delivered in September 1944.

Stay-bolts are usually installed ... How to Boot a Steam Locomotive. or, How to Hostle without really tiring. ... looking for loose or leaky stay bolts, making sure the firebrick lining the sides of the firebox is in reasonably good ...
Longer bolts, like crown bolts, have enough 'shaft flexibility' to allow the bolt-ends to flex with the boiler steel plates, thus the threaded ends generally stay tight thoughout the vagaries of the service, and the very long crown bolts are rarely drilled -- thus the use of the removable caps at the outer ends. For a steel boiler with a steel firebox the stay-bolts should also be of steel for the same reason given above. B. W. Barnfather wrote: Ever-Dur (silicon bronze) screws (or bolts) are favored a lot by steam builders for stays as having non-rusting and high tensil strength qualities and are easy to drill to make hollow stays if desired. Nickel Plate Road 587 is a coal-burning steam locomotive built in September 1918 by the Baldwin Locomotive Works of Philadelphia, Pennsylvania. ... While other volunteers were working on stay bolts, Michelle Yerkeson inserted new copper washers in the outside of each stay bolt sleeve and tightened down a new stay bolt cap. ...

Stay bolt definition is - a bolt or short rod commonly threaded throughout its length and used as a stay to connect opposite plates (as in a steam boiler) that are subjected to a pressure tending to force them apart. Steam Locomotive Construction and Maintenance/Chapter II. From Wikisource < Steam Locomotive Construction and Maintenance. ... The roof stay holes in both the firebox and the top of the shell, when direct roof stay bolts are used, are reamered out with long reamers, and the holes are tapped in position for the stay screw threads. ...
The driver tires on Fort Edmonton's 2-6-2 steam locomotive #107 were worn. New tires were carefully machined as replacements and then installed by Oxford Machine & Welding of Edmonton, Alberta. #5 is in the steam shop as of October of '05 and the stay bolts are being drilled and tubes will be replaced. #5 should be operational for the '07 season. Posted: May 31, 2008 @ 21:05:38 by john heid shay 5 now has its entire front wheel assembly removed, as well as the lower half of the smokebox, to get at the tube sheet. Locomotive boilers are made entirely of steel, except stay-bolts and stays, which are of iron. The crown sheet is supported by what are called radial stays, reaching from the crown sheet to the exterior wrapper sheet.
When a low water condition allowed the crown sheet to overheat, the stay bolts holding the crown sheet would fail with little warning, resulting in a boiler explosion. In a space of ten months, three UK S160s suffered a collapse of the firebox crown, with the first leading to the death of a GWR fireman on locomotive 2403 in November 1943. Locomotive building was a labor-intensive process. While numerous machine tools were used to fabricate components, most assembly was done by hand. The typical steam locomotive weighed more than 100 tons and was held together with thousands of bolts and rivets. It took approximately 8 weeks to assemble a locomotive.
This is known as the tell-tale hole and will permit the escape of water and steam should the bolt become broken. This tell-tale hole is usually 3/16 of an inch in diameter and 1 1/4 inches deep and is drilled at the outer end of the stay-bolt, since almost invariably the fracture occurs near the outer sheet. ... Stay-bolts should be made of the ... Shays were built by Lima Locomotive Works, Inc. and its predecessors in Lima , Ohio . For Shays, class designation (tons) is listed in the following profile. This following table of the Cass stable of geared steam locomotives was first provided by Dr. George Deike for Roster Version 2.0 – and now enlarged.
In a steam engine, the firebox is the area where the fuel is burned, producing heat to boil the water in the boiler.Most are somewhat box-shaped, hence the name. The hot gases generated in the firebox are pulled through a rack of tubes running through the boiler. The Johnson Bar is a storied part of nearly every steam locomotive. It can best be equated to a gear shift, and controls the cutoff of steam to the cylinders. There was wear in the moving parts and linkages in the 924's Johnson Bar, and Ron W. took the lead in rehabilitating this iconic part. It has now been reinstalled on the locomotive.
The tubes running through the boiler transfer heat from the flue gas exiting the firebox to the water contained within the boiler, producing steam. On a locomotive, the firebox is suspended within the boiler by stay bolts and surrounded by water. Below is a schematic showing the 700's boiler, firebox, and smokebox: FEC 253 Steam Locomotive Association 1401 North 2nd Street, Fort Pierce, Florida 34950 We are a group of volunteers that looks to save and restore vintage railway equipment. currently we are looking to secure funding for the last 0-8-0 left in existence the 253 ! the 253 was built by American locomotive company in 1924 and is the only 0-8-0 left in existence.
