Screw Jack?

admin

Can one of you fine gentlemen identify this rather hefty piece for me? A guy from work brought this in today for me to turn it into yardart of some sort.  Another guy was checking it out and said "Its from a cannon"  I laughed. So before I destroy something that could be of some significance Id like to ID first..I think its just a big assed screwjack of some sort. Cigarette pack for comparison in pic.Thx!

Reply:It does kind of resemble the device that used to be used to change elevation settings on the old muzzle loading cannons, like used in the Civil War or on old sailing ships.

Reply:An adjuster or tensioner off some type of equipment, maybe? I'm thinking like a track tensioner? Clearly the "nut" when into a sleeve of sorts... and the push end is just a ball that likely went into a dished socket. Maybe a machine leveler? Just throwing out ideas.
Reply:irnworker433You have the 'business part' of something like these . . . http://www.oldhouseweb.com/forums/vi...p?f=2&t=19925/For 'yard-art' starter components: I would much rather have graduated base - than a 'tape-worm' . . . Opus
Reply:There are big cannons typically at the entrance to city harbors that would very well have had an elevation screw that large. Is it too valuable to make into a paying customers yard art? Probably not unless there is a Historical Fort nearby where you could inspect the cannons to see if it belongs there, not in some ones front yard.Example would be the two cannons in Bayridge Brooklyn overlooking the Harbor as they had 36 inch bores.
Reply:yea pretty sure its from a cannon because of the small round half round ball on top which would fit into the bottom cut out at  the back of a cannon and the taper collar would lock it into the wooden frame
Reply:REALLY appreciate the feedback guys.. Its still kinda inconclusive...  I don't think im gonna do anything with it just yet..Funny thing is, he had 3 of them..scrapped the other 2.  ..  It snowed almost all day today in the catskills.  I mean cmon already..Im ready for flip flops and shorts!
Reply:I thought that it looks like a levelling screw for the base of some sort of heavy machinery. Below is a ebay link to a Joyce screw jack.I think they were to level massive punches or drop forges ?http://www.ebay.com/itm/ANTIQUE-JOYC...item1c50652aff
Reply:i'd go w/  forhires  short version thoughts.   it went in a tube , and a leveler on other end.  whatever it was, probabaly never saw much readjusting.   i'm  thinkin i got something smaller of similar, w/ a hook on outside to go opps. direction.  I'd keep it, clean and oil it up, w/ some add on leverage, it could be a mechanical your mechanical porta power
Reply:I'm not a cannon expert but the cannon elevation screw pictures that come up on google look smaller than this, even on some rather large guns.  They also all seem to have permanent handles, which could just be missing from this piece.  The size and shape of this screw seems more consistent with the house leveling screws.  The round dome would have to contract metal or it would sink into wood.  It is probably round on top to reduce friction when making adjustments.  The shape on the top would be good for lifting anything hard, including a cannon.  It looks like a lot of cannon have a hinge attachment to the elevation device which is necessary of the cannon needs to shoot at targets that are close and below.  I think the odds are against this being part of an artillery piece.
Reply:AH! The PLOT thickens! Didn't realize you are in the CATSKILLS! Bannermans Castle is just down the river below West Point. At one time he was one of the largest Arms Dealers in the United States who sold TONS of Surplus Arms all over the World included outdated pieces! Thinking on this fact of everyone insisting on Jacking Screw, there is the possibility of Wooden Ship building that occurred in that area also.
Reply:Looks more like this to me.I have a pair of the house jacks and there is not a separate nut.

Reply:all the cannon elevation screws I've seen hand the handles attached to them, not a pin type handle that is moved to accommodate a different pull angle. the elevation screws are all relatively small. For that to be an Artillery elevation screw it would have to have been an absolutely MASSIVE cannon. more than likely it's a leveler for heavy equipment. regardless, it's missing several parts so it's value is little more than it's weight in scrap.There are no problems.

Reply:So heres what I came up with for that screw. Wasp/ hornetish. 2 ft. long, 30 lbs. of stingin' fury...No worries, in ten minutes I can have that thing looking like I never did a thing.Last edited by irnworker433; 05-10-2015 at 07:23 AM.
Reply:You need to add a couple of antenna to the head of it, and wasps/hornets have four wings not just two.

Reply:Its not from a cannon. I found some exactly like it on a farm that i cleaned up and have ran across them before at the scrap yard. I almost saved one but didnt know what i would do with it.

Reply:I hauled a load of scrap today and on the way home i stoped at a barn that is now a antique store. On the way in seating outside was on of these. I was going to get a picture of it but i forgot to. It is a monster i would like to know what they were made for.
