In the chats on Sunday night, I have mentioned the "cricket blower" used on the Mogollon Railway. This unusual piece of ?? is infrequently used to blow crickets and grasshoppers off the rails during their "season". THIS IS TRUE: Many years ago, the Bartlett & Western-a Central Texas short line-had to stop operations for several days each year due to the hoards of said critters which ate crops and generally made a mess of things. The locos would slip on the "cricket goo" after rolling over the bugs and it is said that sand on the rails made things even worse. I thought that if the B&W had what the MRy has, they might have been able to run even during the infestation. Well, here it is..



This 4 wheel car has a Ford motor and transmission driving a dangerous metal propellor. The shroud around the prop was added for "safety reasons". Needless to say, the crew gives this thing a wide berth when it is out on the line. The unpowered car is pushed ahead of a slow going locomotive.



The side view shows how she looks. This thing does actually operate, the prop is thrown by a tiny electric motor from a r/c helicopter and there is an even smaller motor inside the crankcase which runs the radiator fan. The "tender" holds a small 3 volt camera battery and the on/off switch is seen behind the diagonal strut-under the frame. Tiny ants (in 1:35 scale they are big old devils) can be blown off the track, of course they tend to hit the operator (me) causing much concern.

To those who wanted to see this, be careful of what you want.

What a piece of brilliant engineering! During the first critical examination, I wondered why the Ford transmission between the engine and the prop looked so large.

Then it came to me

That clever Woodie knew when he was building it that an auto engine turned the wrong direction for the "hand" of the prop- and since there wasn't much call for a cricket SUCKER, he went out in the desert and found an old forward/reverse transmission from a large boat and incorporated that into the build to be sure that it BLEW the crickets.

The man is a genius :brill:

Yep, that's right. You figgered it out Herbronski. That transmission came from the "Dessert Queen" which ran down the Gila River. Yep...

I notice that bit of machinery in other photos and always wondered what on earth it was for.

Now we know..... the rest of the story.

Good day!

Good idea! It gives a new meaning to bubble gum on the track as the 1:1 engineers phrase. L:  Here's a thought,  if you were to have one of giant locusts (grass hoppers) fly into the prop while you were clearing the track things could get ugly really quick for the operator behind the prop. :P

Bob-I would hope the giant locust's goo would get blown downwind from the operator...maybe not. Thank goodness I haven't seen anything like that here. Outside of the tiny ants, the only other problems are giant birds and a monster cat that likes the birds. The cat, I can deal with...the birds are another matter!

Woodie,
if you wanna see a REAL blower, how about this?

http://www.fotocommunity.de/pc/pc/cat/4408/display/10504298

Its the engine of a MIG-17 jetfighter,  used in open pit mines for blowing snow and ice from the tracks. Maybe a model is even useful against giant birds and cats :bg:

Btw, if you don't believe me, here are photos of two other exemplars, even on narrow gauge (900mm/approx 3')

Man-that job with the Mig-17 engine looks like it was built by Acme Co. for the coyote to be able to chase the old roadrunner! I could not see the other link, I am not a member of that site and my German is a little worn-out so I couldn't register. Back to the drawing board.......

Mach 1,03 (679.8 mph) :bg:

No kidding: the "blower" was pushed by a loco, which worked against the power of the jet engine (approx. 20kN = 4480 lbf)

Woodie, here are some other pics of the engine, it was mounted in the yellow boxcar with the "nozzle"
