Title: The Clearance Plate (also known as the Hump Jumper)
Post by: DalronAU on May 29, 2017, 22:53:13 PM
This is right up there with my top favourite gadgets in the sewing room.  Check out the YouTubevideo from the 8.25 mark (or from the beginning, of course  :D ).  This, or something similar, does come with some machines.  The little hole you see in it is used to easily insert a new needle into your machine.

These come as standard with my Husqvarnas. I use them more for inserting the needle.

I've also used it under a walking foot on a particularly thick denim hem.

Oh dear, I'm going to be bankrupt at this rate, I've just bought one  :S they look really good and will save my nails holding the needle in place 😳

Yep, I use a jean-a-ma-jig I've had one for years. If I'm sewing denim I also bash thick seams with a hammer - on the wrong side, makes it much easier to sew.

For inserting needles, I use my dinky little needle threader gadget.  I don't have much call for shortening jeans, but may treat myself to a humpjumper or some such eventually.  Apparently a bit of folded beermat does the job as well...

I use mine for top stitching shirt collars.  Without it my Janome 8900QCP SP and Juki F600 just can't do it without losts of fiddling and coaxing (one stitch at time by the handwheel).

On my modern machine there is a little button on the side of the foot, when pressed it raises the foot to the appropriate height, such as seams in jeans, it automatically drops back down afterwards :)

Mine came today, I've tried it on my industrial machine and don't like it for threading the needle, maybe it's me be because it's unfamiliar, back to finger tweezers on one hand and finger nail on the other! 
It may be better on a domestic machine but I haven't dragged those out yet to try and I've yet to try it with a shank button.

I've had a Pfaff machine for nearly 9 years, and only discovered what it was for sometime last year after I happened to come across a video when it was being used.  You live and learn.

I’m glad I’m not the only one!...I wondered what it was too.

Brilliant Link, thank you @DalronAU ... I have had one of these with my accessories since I have had Ateliers and never had a clue what it was for ...  my manual  said it was for sewing on buttons with a shank or some such thing???  :S

I discovered its true purpose in Austria when @Sakar  finished the last seam of Decembers BOM for me, which has multiple thick layers ... Such a Simple yet Brilliant tool!

@Iminei
I've got an atelier 5 but can't identify this throat clearance plate.
Which foot is it?

My Mom's Viking came with one....back in 1977. We got 25 hours of classes with the machine and they let either of us take them. Maybe it was in class I learned to use it? But I've acquired a couple more over the years, all different sizes and thicknesses.

Off to see if any have the little hole to hold the needle....I don't remember that feature!

I must have at least a dozen of these little blighters, but I can never find one when I need it!

@annieeg  It might be in the bag with your buttonholer accessories, which might be in the back half of the removable bit that fits around the free arm bit of the machine if you know what I mean ???   :S

"in the back half of the removable bit that fits around the free arm bit of the machine"  Sounds like one of those songs from the 60s! 
The jumper just raises the level of the foot. It does help with the shank of a button if you want one for thicker fabrics, also when doing jeans, which are full of thick lumps of fabric. Once the foot is held level the machine has no problem punching through the material. It's when it can't move the fabric through properly that the needle come down out of sync and breaks.  I have a collection of broken needles from when I forget to use that little device.

I have had one of these since about 1988 - with my old Husqvarna. Never knew what it was for and the booklet didn't help. Thank you!!

Thank you for that extra clarification as to how it works TnT ...

I never knew, as I said, what it was for until Sakar showed me.

The Ateliers also have a black button on the side of the main sewing foot which locks the foot level so it doesnt ski slope over big humps and can therefore sew properly

Hump jumpers - they're useful but you don't need to buy one.


For holding a needle, you can make a little pad of fabric, stick the needle point into it and then use that to hold the needle in place whilst you tighten the clamp.


As DF mentioned, folded beer mats (or any other folded paper, card or fabric ) will do the job


Fabrics are different thickness, so are seams and hems.  The plastic hump jumpers are great for thicker stuff but for thinner things, sometimes just using a pad of the same fabric folded to the same thickness works well.


What you're trying to do is keep the fabric feed consistent.  You have to help the feed dogs to keep doing their job by ensuring the fabric is always pressed against the dogs which means you have to keep the foot level, both front to back and side to side.
(It's the same issue that affects button hole feet attachments - gotta keep the foot level or at least pressing the fabric onto the feed dogs evenly the whole time)


For some jobs like edge stitching and top stitching, there are compensating feet for industrials.  We can achieve the same things at home by using folded strips of material to prevent a wide foot from tipping side to side.
For edge stitching shirt collars, button bands etc.  then I often use an old collar or the sample made to test the interfacing/fabric marriage to keep the foot level if I'm using a wide foot machine.

This is the one I got with my Bernina 550QE. Never used it yet.

I sent the link for this to my daughter (who you might remember is a new sewer). She was already ahead of me and had seen this somewhere else. When she went to try and buy one she found that they cost £8. As she is currently unemployed this was too much and she has been using bits of cardboard instead. I am sending her mine - I have managed this long without one!

I’ve never bothered with one as I found a bit of paper folded works just as well.

"compensating feet for industrials."  I have a bi-level foot for my Pfaff,  which is great for edgestitching since it guides a bit as well as levels.
