Carriage Brake Gear

[Dave]

Hello all.
Help required.

Looking at my carriage underframe photo`s, and looking for that illusive detail photo you didn`t take, I was wondering if anyone had any photo`s that show the following, that they are willing to share.
1: Turnbuckle underframe - the 'T' shaped bracket that is fixed to the turnbuckle beam (on the handbrake side) that takes the pivot from the brake rod, just beyond where the handbrake rodding linkage joins the main run.

2: The linkage between the vac cyl shaft and the brake rod.

On most of my photo`s the brake rodding is not present.

Thanks.
Dave.

Which type of coach? Gresley, Thompson, Mark 1?

[Dave]

Hi.
Gresley 60'-00" underframes, turnbuckle and angle truss. I suspect these items are standard on all types of LNER carriage.

Do you mean the following?

[Dave]

Hi Mike,

Thats exactly the bracket I mean on the trussrod underframe.

Thank you for your time in answering this and for posting the photo`s.

The GA plans and brake gear detail drawings show it, but not how it`s actually located, nothing like a photo to make things clear.

Gresley build.

The turnbuckle underframe type finished in the early thirties. It was replaced by the angle-iron type. Generally the turnbuckle u/f had oval buffers and the anglr-iron type had clipped buffers. Thus Thompson builds were always angle-iron.

LNER passenger stock is not really my primary area, and Bill Bedford is the man you want here.

I think you'll find that Mike Trice and 2512silverfox (Nick Campling) are equally well-qualified...

Thanks to all of you for your answers.

Mike has answered part of this already.
All I need is a photo of the linkage to the vac cyl, and do the rods run horizontal or are they angled. From the size of the crank under the vac cyl to the location of the `T` bracket and pivots I think they must run at an angle, but a photo to prove this would be great.

Cheers.
Dave.

These are the best I can do for the remainder. They were taken many, many, many years ago when I was obviously going through a black and white phase.

I really must start taking some digital images to replace these, weather permitting.

Mike.
Thank you for your time spent answering my questions, your photo`s are excellent.
When the weather gets a bit warmer I will go to Pickering and get some photo`s under the Gresleys, hopfully with brake gear attached, I should make the time to go there and help as I am a member of LNERCA, unfortunately work time has dictated otherwise. I will send you some digital photo`s when I get them if you wish.

Snap, also LNERCA member. If you do get a chance they had the Thompson Composite in the carriage shed last time I went (April 2010). Yes please to the photos.

Mike, this part drawing looks just like one which graced my inbox earlier this year... so please excuse me asking a question here. How was the circular motion of the break wheel in the guard's compartment translated into the push-pull motion of the rod which joins the connected levers (close to the vacuum cylinder)?

thank you and regards, Graham

[Dave]

The hand brake winds up and down depending on which way you turn it and that motion is transmitted via a bell crank which links to the hand brake rod which is shown in the drawing at above centre top left. The bell crank pivots about it`s central axis and via the rod and the pivot shown next to the 'T' bracket I enquired about, applies the brake on the bogie.

I hope you got that as it lost me....

Presumably the motion was initially transmitted to the bell crank by the lower shaft of the wheel [ if horizontal on the top of a hollow pillar (was this the case?) ] being threaded, with a threaded collar around it, so that turning the wheel one way or the other caused the coller to move up or down the threaded part of the shaft ??
