All worm gear hose clamps with which I am familiar have a screw or hex drive head tangential to the outside of the clamp, and orthogonal to the axis of the cylinder being clamped. [link]
In some applications, there is little space to use a tool to adjust the screw clamp (imagine a clamp in a recessed hole with limited clearance.)
I propose adding a bevel gear set [link2] to the clamp in order to allow adjusting the clamp along an axis at right angles to the conventional head (either on a radius of the clamp or parallel the the clamp axis.)-- csea, Nov 07 2013 Worm Gear Hose Clamp https://www.google....hose+clamp&tbm=ischConventional orientation [csea, Nov 07 2013] Bevel Gears https://www.google....AQ&biw=1137&bih=747Useful for right-angle drive [csea, Nov 07 2013] This would also help prevent the inevitable loosening experienced with the tangential kind [+].-- the porpoise, Nov 07 2013 [+]
If your worm clamps are coming loose then they're either not rated for the pressure they're containing or you're not tightening them enough. You gotta crank those suckers down until the hose rubber herniates through the perforated band. That deformation is what 'sets' the clamp.-- Alterother, Nov 07 2013 Oh sure, I've tightened those things until the screw head strips. I'm not a professional or anything, but I imagine that normal pressure fluctuations in the hose may be what tends to work them loose.-- the porpoise, Nov 07 2013 [+]-- 8th of 7, Nov 07 2013 [porpoise], it's a rather unorthodox procedure, but you might try rolling up the excess band with needlenose pliers and jamming it under the screw head with a chisel.
They really aren't the optimal fitting for pressurized lines, but I realize they're usually the best you can get at a hardware store. If you use them a lot and they're becoming a hassle, look into folding-band or crimp clamps.-- Alterother, Nov 07 2013 Crimp clamps are great, apart from the need for a hydraulic tool to fit them, and the fact that they're most definitely single-use.-- 8th of 7, Nov 07 2013 There are a style of hose clamps (which I believe are called 'crimp collars') that require only a woodchuck crimper to mash down the 'ears' on each side.-- Alterother, Nov 07 2013 Finally (+) !-- normzone, Nov 07 2013 [+]-- FlyingToaster, Nov 07 2013 //woodchuck crimper//
A what?-- ytk, Nov 07 2013 It's a vice-like contraption used to crimp the heads of woodchucks.-- MaxwellBuchanan, Nov 07 2013 I believe it's part of their adulthood rite, but seems a bit cruel to me.-- not_morrison_rm, Nov 07 2013 We call those Jubilee clips in the UK.-- xenzag, Nov 07 2013 This idea seems to fit here as it is trying to solve a problem that doesn't exist. Right angle ratcheting screwdrivers and small ratchets and sockets have been around for a long time and do very nicely getting at clamps in all kinds of positions. Band type clamps are better and easier on hoses, too. (+) for the complexity.-- cudgel, Nov 07 2013 I've yet to meet a wormgear hoseclamp that I wouldn't have been happier with as the post proposes, even if I had a sideways ratcheting screwdriver already.-- FlyingToaster, Nov 07 2013 Apparently 'woodchuck pliers' is a colloquialism for pinch pliers (aka pinch crimpers).
The hose clamps I'm thinking of are called pinch collars or ear clamps. Anyway, they're better than worm clamps but still kind of annoying. Hex crimp is the way to go if you're invested.-- Alterother, Nov 07 2013 The one's used for pre-mix pop lines are called Oetiker clamps and Oetiker pliers. Is that what you mean?-- 2 fries shy of a happy meal, Nov 08 2013 I bunned this idea but wondered why you can't use a screwdriver or nutdriver from one angle with existing hose clamps but attack them from the side with either a socket driver or a ratcheting spanner?-- AusCan531, Nov 08 2013 I would extend this idea to create a differential hose clamp.
The bevel gear would turn two opposed worm gears of slightly different pitch, both working on the same band which is now a double loop (the excess band of the worm gears being 'joined up').
This would permit ludicrous amounts of tightening power. It might be a little difficult to construct the continuous band though.-- mitxela, Nov 08 2013 Great idea! [+]-- Grogster, Nov 08 2013 Very similar, [fries], but not as complicated. If memory served oetiker clamps have little square perforations to lock the band in place, while the pinch collar is thick enough to simply stay crimped on its own.-- Alterother, Nov 08 2013 random, halfbakery
