The more familiar cast tank saddles seem to have started circa 1918.

I am looking for drawings for vertical wheel type Universal hand brake. I would like to make it in 1-1/2" scale

Thanks

Tim, 

   I wrote “I believe that the water columns in the photos are of the Poage design", and then you post an image of...………..a Sheffield design asking "so where is it? 

         Apples, oranges Tim....?  

         Of water hammer Dennis, I have copies of some internal NP paperwork regarding the standpipe at the NP’s Rice’s Point facility in Duluth, MN. The facility was at the base of the surrounding hills and about 14 inches above Lake Superior's mean water level. (Yes, the inspection pits in the roundhouse were waterproofed, and yes, in times of storms if the wind was right, waves from the bay could and did wash up on the south railroad tracks of the yard. A break wall was put in to deal with it. However if you go there today, it has all changed with the freeway adjacent.) 
        The railroad had hooked up to the municipal water supply in the 1920’s with an 12 inch ci pipe. The city authorities reported to the NP that at times there were reports of significant water hammering by business’s in the multi-block area surrounding the roundhouse. It was tracked down to the opening and closing of the railroads standpipe. The supply pipe from the city mains was then rerouted back to the railroads water tanks, the pipes to the standpipes were re-plumbed to the water tanks and these provided a buffer to the several hundred feet of rushing water from the city main.   

    Tim, there are two Sheffield brochures currently on eBay that could provide an answer to your question if you are interested in following up on it. I will follow my modeled railroads standard plans.

       However, regarding freight car content, I think this is getting close to where the Sherriff may come in. Too nice a day here to risk jailtime.                                    Jim Dick - Roseville.

 

Tim,

The item is not listed as in-stock at Intermountain and they have been caught in the Chinese closure mess. Check Des Plaines, Caboose, Klein and Walthers and other vendors. Somebody out there probably still has some.

I did the CMO and IC cars using Front Range bodies with the ends removed and Intermountain parts. That gave me diagonal panel roofs and some fairly decent ladders for my parts stock.

Yours Aye,

David has said before that PTC frames from about 1912 to 1916 look exactly like
STC underframes built beginning in 1916, when both PTC and STC changed designs.
It's very confusing! :-)

Tim O'

"Why do you think the Ohio Cities Gas Co.car was built by Pennsylvania Tank Car?
Brian Leppert Carson City, NV"

 Standard Car Construction Co. (STC's predecessor) started in 1915 and didn't build cars in quantity until 1916, while high-walkway cars with the stereotypical "STC" underframe appear in the ORER entries for Pennsylvania Tank Line (PTC's leasing arm) as early as 1912.

Tony’s right - even with a responsive museum to the hobby, until someone, usually a volunteer, takes the time to inventory and catalog them and then enter them in a computer system - which could be years - all these items are lost to the hobby.  Good luck getting anything from the UPHS!  The Newberry in Chicago has a vast collection of drawings, correspondence and even some photos - like 50,000 pieces - and they are very nice to talk to - BUT about 80% of their received material are in boxes uncataloged and hence unobtainable and have been sitting there for years.  If anyone has any volunteer time on their hands - they could go to the Newberry and help do some entry work

I'm not sure that "vacuum breaker" is the proper description of the bell shaped part's function; I always thought it was the counterweight for a relief valve that prevented water hammer when the filling valve was closed. In the case of the Sheffield model in the ad, it has a spring loaded relief valve down in the pit which serves the same purpose.

Not all K brake installations were the same. I’ve seen photos with the K brake cylinder pointed out towards the end sill and the opposite, with the cylinder pointing towards the slope sheet. 

The USRA twin hoppers were built with KD brake equipment arranged like this. No brake diagram in the 1922 CBC, but there might be something in the 1919, which would be in the public domain.

Wish I could help.

so where is it?

Then I realized you are using LEDs.

    I have been using 402 LEDs purchased prewired* for passenger car lights.  I think they would work for those who don't want to do the soldering.  Of course they are a little more expensive.
