    Default For the "Olde Fahrts"

    Thought some of you guys would appreciate this. Chiefengineer11 and I went down to the Fire Museum of Md, (Lutherville, near Baltimore) for a once-in-a-lifetime "Gathering of Ahrens Fox" Fire Apparatus. People from near and far brought their foxes.

    That's cool!!!

    There was an Ahrens Fox at our dept 150th and it was quite the sight to see it pumping.

    BTW, coming from a young buck, it's not just for old farts

    I'm not an Old Fart, unless you take my LCpl's word for it, haha. But I love those beauties. Ahrens Fox made some real beauties.

    I have heard a couple of different stories on the function of the mirror balls.

    What was thier purpose?

    Their purpose was to reduce the pulsations in the discharge lines that are inherent in any piston pump. From watching the lines being used at the pumping demonstration that was put on, reduce is the proper description, not eliminate.

    What CE11 said, Any piston pump produces pulsations. The "mirror ball"is an accumulator to smooth out these fluctuations. T.C.

    Talking

    Think of it as an expansion tank on your heating system, same concept to equalize the pulse pressure wave.

    To add on to that, if I remember correctly the globe had air in it and the pump would fill the globe compressing the air and the air would push the water through the hoses, with the piston pump serving to fill the globe. One of the books I read says that this design was even employed on some hand pumpers.

    air compresses - water doesnt (actually VERY little)

    What's actually happening is that on piston upstrokes, some of the water is going into the dome (path of least resistance) and compressing the air head until the air pressure equalled the pump pressure. On downstrokes (lower pump pressure), the air is pushing water back out and into the discharge port(s). Those actions smoothed out the pulsations in the lines, but not by a long shot did it completely eliminate them.

    The first year I was at my college Fire department we ran a mid 40's Buffalo with a piston pump so I remember those pulsations well.

    I pretty much died later that year and we replaced it with a Dodge Power Wagon with a front-mount pump and a 250 gallon water tank.

    Buffalo with a PISTON or ROTARY gear pump? We have a 39 with a rotary gear, I'm not aware of a Buffalo with a piston,not that it isn't possible. T.C.

    Wonderful that so many have been kept in working condition. They were a FINE machine,ahead of their time at the time. STILL will give a NEW rig a run for the money. T.C.
