Do I Have A "complete" Busm / Pearson #6 - Or What?

[gordond]

interesting array of parts there - a few changes to suit the motor [extended main shaft and pulley] plus mount adages on the stand.

there are few different things about this machine - stitch lever and associated cam.

Interestingly mine has no bolts, mine has brass studs and a washer on each side but maybe the studs are left threaded. So I´d guess mine had probably a metal rod. Some pictures:

Yes, mine was motor driven but seems a couple of parts are missing to get the clutch mechanism working. I will strip it down for treadle use. So I may have some parts I no longer need. I´m not a collector, I´m a user so maybe someone else can use the parts for restoring another machine.

I just noticed most parts are marked with 6HM so I would guess when the Pearson´s / BUSMC´s have the same numbers they will be interchangeable.

How is the stitch lever and cam looking on your machines.

There is not much documentation for these machines so maybe we can put together some detailed pictures for comparison.

I also noticed IVI markings - is it an abbreviation?

And what is this box for? I found no place where I could mount it. The stud fits in a hole on the arm but there are not threads of holes for screws. I thought it could be s spare parts box or so but Im not sure.

And some more pictures of the bobbin winder. The spindle for the thread roll is missing as it seems.

So this is how it look temporarily assembled - I have to buy some nuts + bolts

[gordond]

The box is a wax pot. ..should be bolt holes in the machine body....IVI is I think was a associated or subsidiary company- needles were labeled as IVI

I will take some more photos today and post later to clarify the differences.

Photo of stitch arm cam

via phone in the basement. .excuse the low quality awkward photos

I see - really different! Mine has the stitch length adjuster on that end. The scale shows a max. stitch length of 3 1/2 and the max. RPM of 420 rpm´s. Where do you adjust your stitch length? Seems you can´t do it on the cam, right? Can you post a picture of the backside of the machine w/o stand?

BTW - this morning I just found this website of the British United Shoe Machinery History group:

www.buhistory.org.uk/tag/machinery

And when you scroll down you´ll find a video of a CO. called IVI METALLICS - so I´d guess this the Company that produces metal parts for BUSMC and did the cast iron work too.

yes ..stitch length adjustment - missing /or different configuration indeed-- even the original Pearson had the dial on the front-- you have a radically different machine...guess it is set on the end of the stitch length arm from what I can see.

inc' older photos for better viewing [plus an IVI reference from a 1911 BUSM catalogue]

Thnaks for the pictures.

Okay - found the holes for the wax pot but why a 3rd wax pot on the backside? What is it for?

I wonder which machine is the later production - yours or mine? I have found a number on top of the head. Is this the serial number?

I also have found another USM / BUSMC 6 with stitch lenght aduster on the back. But this one is made for (or in) France.

This is also the "cheapest" BUSMC I have found

Steve [singermania] might be able to answer that - he has some outstanding complete wax heating setups on some of his machines..he could answer any question on these.

With the population size here - HM6's are in the low numbers - so we rarely get to see anything remotely complete [or even a remnant of the brass wax gear] -

the rear pot is tubed through to a front wax apparatus - waxing the needle and thread [stephen in Canada-GreenMan leather has one] - found the photo of it

I have the following 4 x no6's : original Pearson : # 5041...BUSM HM6 : # 7006..#7114..#7536..

I think Les [in the UK] said that the numbers produced went up to 11480 or something like that

interesting has a G prefix [Germany I guess]

that's great finding the reference - makes sense now -the new "improved" model- hehe!- yep- gotta love that price!

It's not a wax pot, it's a water reservoir for the hot waxing system. There was a pipe that went from it though a hole in the machine to the water bath on the front when they were fitted with the hot waxing apparatus.
