sandyt Report post Posted September 2, 2011 Hi, Today I bought a sewingmachine from a guy. The same guy also had a neglected protos sewingmachine in the back of his shed. It is a needle and awl. I can't find any info of this machine. Does somebody know these machines? Are they any good for leather? I think it has needle feed. The pressure foot was up and didnt go down. Is this supposed to be or is it rusted in place? Without the rust, it should look excactly like this. Any info is welcome. Sandy. Quote Share this post Link to post Share on other sites
CowboyBob Report post Posted September 2, 2011 Sandy, It looks like a Puritan to me.It uses a single needle,cotton thread(needs to be lubed)but it makes a chainstitch meaning there's loops of thread showing on the bottom.These amchine are used for horse collars,footballs & once ib a while for boat anchors.

Cobra Steve Report post Posted September 2, 2011 Hi sandyt. As Bob said, this machine is a chainstitch machine. You want a lockstitch, not this machine. A chainstitch machine is used on the top of dog food, or sugar, or other types of bags (and some garments, however this would be 2 thread chainstitch), where you can pull on the thread and it will come un-done. A lockstitch machine has a needle thread and a bobbin thread. Thanks, Steve Quote Share this post Link to post Share on other sites
CowboyBob Report post Posted September 2, 2011 You might need to oil it to get it to free up,the foot lifts up when the needle pulls the leather back,then comes down as the needle pulls out.These machine are fun to play with & will run pretty fast. look here to see one sewing Quote Share this post Link to post Share on other sites

sandyt Report post Posted September 2, 2011 Thanks Steve and Sewmun. It's clear to me now what kind of machine this is. Didn't know these machines at all. Only now I realize there wasn't a bobin indeed. So the stich comes loose when the tread breaks somewhere? Thats's not good at all!! But I am still curious though. I asked the seller to hold it for a week so I could think about it. So I will think about it. It's realy hard to not try a 'new' machine, haha... Playing with machines is fun. Just bringing a 'dead' machine to life is satisfaction enough most of the time. So thanks for the info!!! Sandy. Quote Share this post Link to post Share on other sites
amuckart Report post Posted September 2, 2011 (edited) Here's a video from Campbell-Randall's youtube channel showing one being tested. You can reasonably clearly see the loops on the back Edited September 2, 2011 by amuckart Quote Share this post Link to post Share on other sites
CowboyBob Report post Posted September 2, 2011 No,but guess what they do @ this factory @ breaktime? Quote Share this post Link to post Share on other sites
sandyt Report post Posted September 2, 2011 I think you got the wrong link Amuckart. But the video below is the right one. Sewmun called it puritan? What does that mean? Anyway, after searching with that word I found that vid you ment. Thanks. Sandy. Quote Share this post Link to post Share on other sites
CampbellRandall Report post Posted September 2, 2011 You might need to oil it to get it to free up,the foot lifts up when the needle pulls the leather back,then comes down as the needle pulls out.These machine are fun to play with & will run pretty fast. look here to see one sewing Bob: That is actually a Union Lock-Stitch (made by Randall). All of the Wilson NFL footballs are made with the Union, while the general production balls are done on the Puritan (there should be another video with the Puritan). They use the Union since the stitches are cleaner and pull tighter than a single needle machine can sew. Otherwise, the seams would bulge under pressure. - Dan Naegle Quote Share this post Link to post Share on other sites
CowboyBob Report post Posted September 2, 2011 Hello Dan, Oops I looked @ the video again alittle closer this time & seen the Union,it makes sense too that they'd need a stronger seam on the NFL balls. Sandy, over here Puritan is the brand name. Bob Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted September 3, 2011 I sew all of my heavy leather jobs on a Union Lockstitch machine. There is only one type of machine that is more awesome and that is a Campbell-Randall High Lift or Cyclone. Quote Share this post Link to post Share on other sites
Trox Report post Posted September 3, 2011 Protos 3 needle chainstitch sewingmachine Quote Share this post Link to post Share on other sites
sandyt Report post Posted September 4, 2011 Thanks Trox. Now something else falls in place. A few months ago, I saw a youtube vid about a three needle sewingmachine. It had this excact sewing 'action'. Never did understand how the mechanism work with the bobin. But only now I understand. It had to be a chainstich machine also. It uses no bobin. Sandy.

Wizcrafts Report post Posted September 4, 2011 The Puritan machines (and Protos I guess) are used in the golf bag, luggage and rifle bag industries. The sewing I have seen uses waxed linen thread. It will not normally unravel and breaks only with great effort, or a Hyde knife. Quote Share this post Link to post Share on other sites

CowboyBob Report post Posted September 4, 2011 Yes,there is different chainstitchs,on jeans they use 2-threads,there a looper underneath that has a thread on it. Bob Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted September 5, 2011 There is a world of difference between the chainstitches made on a Puritan and those made on industrial garment sewing machines. The garment machines run cotton or polycore thread direct from the spools to the tensioners, to the needles. Pull the wrong way and the entire chain can unravel. Professionals who use Puritan machines run 3 to 6 cord, left twist, Barbour's Irish linen thread through a liquid wax in the closed-top wax pot. After a while, the wax hardens in the sewn material inside the chain stitches. Once the wax hardens, the stitches cannot be pulled apart in a chain, unless one exerts tremendous pressure, or cuts them with a sharp Hyde knife. I know, because I have had to work on items sewn on Puritan machines, and only a sharp knife got those stitches apart. Some were over 50 years old! If anybody has a Puritan that they just plain don't want, send it to me! I'll be your Huckleberry! Quote Share this post Link to post Share on other sites
vogue Report post Posted November 23, 2011 I have a Protos,chain stitch,no need bobbins. It is almost same as Puritan machines. Also uses same needles&awls. Protos sews 1 or 2 or 3 raw stitching. It is cheaper than Puritan. matt Quote Share this post Link to post Share on other sites
