Thread: What Is This?

Popular Science - Google Books

Doesn't say how it works, but it does have a picture of it in action which should give you an idea of what's going on with it.

Is it an adjustable fence allowing you to run a circular saw along it? Looks like it may be a bitdangerous!

cheers, but i already googled the crap out of it and found that pic
i found a link to a german site where there was a lil convo on it, )good on ya google translater) but still nothing that really gives any decent info

i even did agoogle patents search, and... nothing

yep thats what it is lol

i already know that,
its made to go into a workmate (collapsable bench)
so when in use it would be secure....
i dont have the attatchment nor the workmate, but i can easilly adapt it,
and i probably will if i can get info o it...
will be good for cutting up slabs that i cant get on the tablesaw,
even bolting the saw on and clamping the fixture to a slab will beat free hand cutting with a circullar saw through thicker stock...

i wanna know more about it

It probably pre-dates the USPTO searchable database, but this might be close: 5445056
Assigned to B&D, and includes "mitre" and "mate."

A reference cited, of the same era as the Popular Science article (1976) is 3998121. That might be closer.

Google patents has single-file pdf's, better than the USPTO versions.

Cheers,
Joe

cheers for that,

but both of those seem to be your basic everyday overhead sliding mitresaws

The link to popular science was FABLOUS. The ads towards the end were a riot. I especially loved the ad for the books by J Paul Getty that contain his secret to getting rich on page 133. Brilliant stuff! If only the address were still valid...

Hi Andrew,

B&D made in this accessory in the 70's and it was supposed to take most 7 1/4 inch circular saws made around that era. The object is, to lay the hingeable arm along a piece of wood and fix or clamp the two together in some way. Then rotate the length of sliding profile rail up to the desired angle, which is readable on the dial. The profile is to then be arrested in that angle by the clamping screw at the rim of the dial. Then the running saw on its sled is to be pushed along the rail to cut the clamped piece of wood underneath, like it would be done on any other sliding rail accessory.
One of the four pics i found on internet, shows two attachments bolted on the rail, that could be some sort of lifting feet. If i'm correct in this and if these feet would be clamped on top of a workmate or bench, the profile with the sled and saw would sort of hover, as it were, with some space underneath. In that case the profile rail with the sled and saw would be the fixed part of the contraption, with the rotating arm determining the angle of cut being the part with more freedom of adjustment, which could be handy for quickly sawing several small pieces of wood (picture frames and such). But i'm not sure if this is the true purpose of these hook-like attachments in the third pic.
Users told from experience that the accessory performed well, but was found to be too short in many cases, like a Festo FS80 rail would be for a person wanting to saw plate material.
