Hi Pete. I remember that the DKS coupler was very promising in description. I've was interested to know what happened. I will go check the thread regarding the True Scale offering by MTL. Thanks again Pal
I just saw a new released item from Micro trains that I found interesting. It is called the True Scale coupler. I remember a few years back our friend David K Smith was working on more scale appearing coupler. I was very interested in what he described and it was my understanding that he had submitted the designs for patent. I don't recall what ever happend and I am now wondering if this new release from Micro Trains is the David K.Smith's coupler design perhaps through an agreement or acquisition? Nonetheless it is very interesting.
I thought there was some testing of the couplers by a select few TRW members? If so what was the impression of the coupler.
Check out the thread that @peteski referenced above. You'll see their impressions.
I was refering to DKS coupler. not the MT coupler referenced in Pateski's link.
I could be wrong, but I don't recall anyone beta testing the ProtoMate coupler. In fact, I don't remember ever seeing a physical coupler, so I'm not sure that DKS ever even had a working model. Boy, do I regret that the Protomate never came to fruition. Hopefully, MTL's new scale coupler will fit the bill.DFF
Right of the bat those are totally different coupers. ProtoMate was much larger, compatible with other N scale knuckle couplers. It was also designed to be a fully-automatic magnetic coupler. It however was closer to size and closer in appearance to the AAR coupler than any other N scale knuckle couplers. So, it is totally different than the MTL scale coupler. We are talking apples and oranges here. The only common things about ProtoMate and new MTL is that the lack of the metal centering spring (which equates to no slinky effect).The Arnold coupler used on their newest models is probably the closest we can come to DKS' ProtoMate. But it has its own set of problems.
DKS's Protomate patent shows metal springs. It does eliminate the slinky, however. But the centering action is a metal coil spring.
