Canadian Airchime J3 Snow Plow Whistle 1956 ex-CN plow #55126
This Airchime J3 Snow Plow Whistle is for sell. Contact me if interested.
01/09/2017 Here is my sand cast Airchime J3 Snow Plow Whistle with Made In Canada back caps. I got this horn on 01/09/17 from Sean Lynn that had bought it off eBay on 11/30/2016. You can see it still has some CN red/orange paint traces under the black paint. It doesn't have a tag like most of them did. I have seen them both ways with tags and without tags. Can anyone shed some light on the tags? There are no holes in any of the bells for a tag. What I am thinking this J3 was most likely 1 of the last few that were made. Also the #1 bell has the MODEL J3 SNOW PLOW WHISTLE cast into it. The #1 bell also has the cast in early 3rd gen nozzle without the diffuser rings along with single diaphragm and cushion. The same goes for the #2 bell as well. The #3 bell is a Fat head bell it has the 3 tabs cast in just like the K bells had for mounting the diffuser rings. The only difference is that they were never drilled as a standard K bell was for the diffuser ring. From what I know this is differently an ex-CN J3 horn. I know for a fact the J3 came from the eBay seller in Sainte-Sophie, Quebec, Canada and there is a big CN Diesel Shop and Yard in Montreal, Quebec, Canada there only 41 miles apart. I am almost certain that this J3 Snow Plow Whistle was off of CN 55126 Snow Plow. Because it has the same bells reversed when it was sold on eBay. I will be setting this up with a 30 gallon ASME 200psi Manchester Tank with my new Quincy reciprocating air compressor and it's 30 gallon air tank. With 1/2id hose with a Graham-White 353-100 1/8" (24 SCFM) and (70 SCFM) in the full open position. And I will be running at 100psi to 110psi on the Airchime J3 horn. I took the J3 all apart and gave it a real good cleaning. I think it should sound awesome because everything in the horn was in excellent shape.
The sand cast J3 Snow Plow Whistle uses the early J-series bells 1, 2 and 3
Original factory tuning was: D# minor triad 1 D# (311 Hz), 2 F# (370 Hz), 3 A# (470 Hz).
01/13/2017 Here are a few pictures below of my Airchime J3 Snow Plow Whistle with Made In Canada back caps. Well the J3 arrived today from Sean Lynn. Here are a few things I found out when I took the horn all back apart to clean it with OSPHO phosphoric acid for the white rust that was still on the horn. The J3 colors are red first then orange and then finally black. And at some point someone also painted the horn metal flake blue which most of it has fell off. And it has punch marks on all 3 of the bells J3R2 as the picture from eBay. Also the manifold has a .125 cast in restrictor in the base of the J3 manifold and all 3 bells have .125 inlets also. From my sound tests on my bench these J3 horns aren't as loud as per say a sand cast K3L that I have. I have heard a few of these J3 Snow Plow Whistles on You Tube serial 4523 and they sound haunting to me. Also the plow picture below was taken 01/22/1977 in Montreal, Quebec, Canada were the J3 came from.
01/11/2017 Here is what I do know in 1955 sand-cast K production begins. I have a known J3 serial #4522 would be 1958 and it has Fat head bells #1, #2 and #3 bells. And all have the 3 tabs cast in just like the K bells had for mounting the diffuser ring. And the serial tag is on the J1 bell also. On this J3 here without the tag on the #3 bell. That #3 bell is a Fat head bell and it has the 3 tabs cast in just like the K bells had for mounting the diffuser rings. The only difference is that they were never drilled as a standard K bell was for the diffuser ring. This known J3 serial 4522 is 1958 and its #1 bell has the 3 tabs cast in and it still has the MODEL J3 SNOW PLOW WHISTLE cast into it. I do know they stopped sand-cast K production in 1976. My question is does anyone know when they stopped making the J3 bells?
Below is the J3 horn I am talking about for reference. By: Reed Skyllingstad
01/11/2017 I asked this question. My question is does anyone know when they stopped making the J3 bells?
Here is the answer I received from Josh Simmons. "All J bells with the later
style fat heads have the cast diffuser bosses. Only the early style flat heads
do not have the bosses. It's been years since I've had mine apart, but I know
all three bells are the fat head style and have the cast diffuser bosses.
01/16/2017 "From what I've seen, the earlier "flat head" style J3s had the tag on the 3 bell of the horn. The later "fat head" style had the tag on the 1 bell. Although all three bells are indeed J bells, I would speculate that the 3 bell is a replacement bell. The original flat head 3 bell would have had the tag. Just my speculation. Still a nice horn that is strangely hard to come by these days considering hundreds if not thousands of them were made back in the day."
So from what Josh stated above I to think that this is an early style flat heads on the J1 and J2 bells they both have no cast in tabs for the diffuser rings. On my J3 bell it does have the cast in tabs for the diffuser rings. I am going to say that the J3 bell on this horn is a replacement bell because original J3 bell got damaged and the tag would have been on the original J3 flat head bell. I agree with Josh that the J3 bell was replaced bell. From what Josh said above about the tags location on the early flat heads the tag was on the J3 bell. And the tag was on the later fat head cast in tabs on J1 bell. I am going to guess this J3 horn I own now is early 1956 or early 1957. I will update this information if I get anymore to help put an exact date on the J3 horn bells with cast in tabs started. I want to thank Josh Simmons for the above information.
The sound clips below were taken at Van Meter slat dump on the old railroad tracks. This is one of my favorite places to honk my horns at. Also in the sound clips I set the Zoom Hn4 up at the tracks and then I drive down the road to the bottom by the river. Then I start honking my horn about 1/2 back up the hill to the tracks. The road is like a snake and for speed it's not that fast because the road isn't that wide and if someone would be driving by you couldn't pass each other. The physical address of this location is 351 Darr Rd, Smithton, PA 15479
02/04/2017 @ 25 degrees Here is a drive by recording of my Airchime J3 Snow Plow Whistle with Made In Canada back caps horn. That I made at Van Meter slat dump on the old railroad tracks @ 110psi and with 3/4 out of the 30 gallon tank to 1/2id hose. With 1/2id hose with a Graham-White 353-100 1/8" (24 SCFM) and (70 SCFM) in the full open position.
Factory tuning was: D# minor triad 1 D# (311 Hz), 2 F# (370 Hz), 3 A# (470 Hz).
Here is what I came up with using Audacity 1 D#4 (312 Hz), 2 F#4 (373 Hz), 3 A#4 (456 Hz) I got these Hz from the above sound drive by sound clip I made.
