Job Specific Sewing Machines

[Evo160K]

While searching for a picture of a particular Singer 45K, I stumbled upon this unusual Union Special bag closing machine that I thought was pretty trick.  I'm fairly new to sewing machines, so this one may be old hat to many of you.

Perhaps it would be interesting to see pictures of other unusual job specific machines..... particularly leather.

I saw a picture once of a huge, long arm, Singer on a stand that was being used to sew aircraft wings onto fuselages. You read that right, I couldn't believe my eyes,  I tried several times to find it again, but couldn't.  Anybody see that one?

Hi Al, Hows things???What 45k were you looking for??? 

I used to use one of these machines for sewing sacks when i stayed in London. It was like one of those electric jig saws for wood.. same sort of size and when you finished the sack there was blades for cutting the thread, you just turned it into the blades. (not a very interesting job that one?? making muesli by the ton

Was this the singer you were looking for Al???http://www.sil.si.edu/DigitalCollections/Trade-Literature/Sewing-Machines/NMAHTEX/0148/ 

this one is for Aeroplane Hangars....

For sure a handy machine - you never know when you have to sew the next airplane hangar for you friend or neighbor.  I think last year we had a post with this Singer 8-8 machine - not sure if Bob @ Toledo Sewing had one - or so - do not recall.

I don't have a Singer 8 but I did pick up a Singer 7-31 last year and it is an absolute beast. I still need to figure out how to modernize it with a new pulley so I can use it with a servo motor. I've only used it by hand so far to see if it stitches and it punches through harness leather at 12 ounces like nothing. Unfortunately the shaft I need to find a pulley for is a weird size 1-1/16" on the I.D.. Can't find anyone that makes a belt pulley in that size so I'm thinking I will need it custom made.

These bag closers are popular not at all unusual, we sell a few a year of the Consew model CN10NS is a common one, CLICK HERE

Jimi, we're okay here, thank you.  Hope you're the same.

That's some unusual job specific machine pictured in your link.  Is that lower spool of thread continuously feeding the bobbin?  Isn't that' sort of the holy grail of sewing?

The machine Singer made during WWII for Boeing had a very, very long arm and sat maybe 7-8 feet in the air on a roller stand..... incredible looking machine sitting along side a bomber.  Sure would like to see it again... other unusual machine as well.  Those job specific machines are fascinating.

Get a flat steel pulley with large enough center to go over the shoulder of the wheel & drill through the side of it & the handwheel that is on the machine,use 3 or 4 bolts & nuts evenly spaced.

For sure this will work, or get a 7-33 handwheel and bore it out for the larger 7-31 top arm shaft.  We used to do this a lot.

I think that cone of thread on the floor is for refilling the bobbins Al, you can see it in the first picture.

Thanks to both of you for the ideas. I was actually thinking og doing BoB's idea. I'm wondering if I can just bolt the wide belt pulley that was set up as a pressure clutch and then just put a wide pully on the servo motor and just make my own belt.
