what is this Dumore thing really?
I have a motor that currently has an arbor and a 4 inch buffing wheel on
it - the motor is on a cast iron stand which houses a rheostat with a sliding lever - it is pretty old - looks like it's easily pre WWII - the motor says DUMORE type KB on it - screwed to the top of the motor is a chrome plated bracket with a vertical hole through it. I am deeply suspicious that this was not originally a buffing machine - for one thing the vertical hole in the bracket makes no sense - I'm imagining that it might have been a flexible shaft grinder/tool like a foredom type tool but my attempts to search for DUMORE type KB have turned up nothing - so I turn to this agust body where someone is likely to have a hint or a pointer to what it really is. I can take a photo and put it in the drop box if that would be helpful - but the thing is pretty unpretentions - the motor is a brush motor, a bit larger than a sewing machine motor, everything is painted black (the old shiny black, not wrinkle) and the Dumore label is aluminum with the numbers stamped into it - and there is some gold color in the DUMORE logo. any ideas? links? -- Bill www.wbnoble.com ** Posted from http://www.teranews.com ** |

Toolpost grinder for a lathe . -- Snag '90 Ultra "Strider" '39 WLDD "Popcycle" Buncha cars and a truck no, whatever it is, it is NOT a tool post grinder - it sits on a pedestal type base that houses the rheostat, the base has rubber feet, there is no means to mount to a tool post - whatever it originally was, it sat on a bench when doing its job. I thought there might be someone who had a "history of dumore stuff" type web site they had found that would help - I'll try to get a photo into the drop box in the next day or two unless someone can recognize what "type KB" might mean ** Posted from http://www.teranews.com ** |

Sounds like a variation on this, From a 1924 catalog: "Type D Dumore Universal Motor 1/8 Horse Power Type D is adapted to jewelers' and dentists' work and is efficient on general polishing and buff*mg. Finished in black enam*el. Equipment includes wheel arbor and emery wheel, tapered spindle, 8-foot cord and attachment plug, and a five-speed rheostat in base. Length, 5-5/16 inches, not including shaft extension of 1-1/64 inches on both ends. Shaft diameter, .375 inch tapered on ends. If desired, Ritter Chucks or 5/32-inch Goodell-Pratt Chucks may be used on this motor. Diameter of motor case, 4-3/8 inches. Measurement of base 5-1/4 inches. Net weight, 12-1/2 pounds. Shipping weight, 15 pounds. Price, each $27.50" They made smaller, with only an arbor at one end. A pic would help Tom |

The chrome thing, could have been a mount for a shield. Or a light. Or it has nothing to do with either, and instead, was part of the maybe original use of the motor. Goodal-Pratt made a wide variety of tools and measuring equipment. No telling if these two parts (the motor and arbor) started off together, but they are together now, eh? Cheers Trevor Jones |
