What is a "hoop gun?"

I think it is "hoop construction" for a gun, i.e. fitting hoops around the barrel to strengthen it. I believe the boiler of the Stanley Steamer was wound with piano wire under tension for the same reason. Biscuittin (talk) 17:35, 1 February 2008 (UTC)[reply]
Correct on part 1. The hoops helped resist pressure in the chamber, which cast iron wasn't so good at. (Also casting wasn't so great then...) On part 2, never heard it before, but it makes sense.

A hoop gun is different from a wire gun. A wire gun construction is where wire under tension is wrapped and built up around a barrel. A hoop gun is where red hot or hotter iron hoops/sleeves are layered up upon a barrel and allowed to cool. Thus, shrinking and securing themselves into place. That is at least the "Basic" version but I suggest looking at their respective articles if you want more information.(CaptianNemo (talk) 20:50, 30 August 2012 (UTC))[reply]

++++++++++++++++++++++ Did the man invent the Torpedo Boat Destroyer or the Torpedo Boat? -4.226.120.136 20:41, 30 July 2006 4.226.120.136 20:42, 30 July 2006 (UTC)James[reply]

The claim is for torpedo boat; the TBD was a reaction to the TB. TREKphiler hit me ♠ 03:36, 18 September 2009 (UTC)[reply]

ambidexterity

[edit]

From the dusty corners of my mind comes a memory of a high school book report on the Ericsson and the Monitor and this factoid: that he once broke his arm and instead of waiting until he was healed so he could get back to his blueprints, he simply taught himself to draw with his left hand.

Fair use rationale for Image:JEFEricssonMemorial.jpg

[edit]

Image:JEFEricssonMemorial.jpg is being used on this article. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.

Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Wikipedia:Fair use rationale guideline is an easy way to ensure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.

If there is other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page. Note that any fair use images lacking such an explanation can be deleted one week after being tagged, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you.

The Times, they aren't a changin'

[edit]

Frankly, I'd prefer a better, more reliable source than the 1921 NYTimes... Preston, for instance, whose history of DDs doesn't mention Ericsson having anything to do with it. TREKphiler hit me ♠ 03:36, 18 September 2009 (UTC)[reply]

Question on nationality

[edit]

How is he American when he didn't move there until he was 36? Born and raised in sweden, early career in England...

Well it says "American Swedish-born...", the reason seems to be that he "primarily came to be active in the United States". To me, using the phrase "American Swedish-born..." and "Swedish American" is fairly similar, but the latter could perhaps be more correct. Tomas e (talk) 15:18, 28 October 2009 (UTC)[reply]

Article needs better structuring

[edit]

One quick flick through the 1906 (or 1911?) biography by W.C. Church makes one realise that the whole Ericsson article is a just precis version of the book. And that's problem No.1 - the book was written from an 'American history' perspective, with maybe only 10% devoted to his achievements in England. It needs to be more balanced. Problem No.2 is that Ericsson was so multi-talented that he had his finger in a lot of inventive pies. The article needs to reflect this better, with ordered sections, to make it easier to keep up with where he was and when he did what. Three similar page-images of him is a bit much too, one of them should be deleted. I'd do it but I've no more time - it took me AGES to track down "the celebrated Astor House fire" mentioned in the article, which turned out to be in reality "the memorable Argyle Rooms fire" of 1830. When's a fire ever "celebrated", I wondered.. but oh, the effort it takes! I can see how mistakes like that get left for years, because they're so hard to check up on. Pete Hobbs (talk) 04:21, 5 August 2011 (UTC)[reply]

Ericsson worked with Francis Pettit Smith when in England. — Preceding unsigned comment added by 95.150.18.228 (talk) 08:04, 5 May 2017 (UTC)[reply]

Hot Air Engine

[edit]

Apparently post 1859 era a Captain CHARLES L DINGLEY purchased a ship called The Ericssan of 1,645 tons this was the vessel built by the famous engineer of the same name to try the hot air engine as a motive power in ocean navigation. Source: http://books.google.com/books?id=KH8rAQAAMAAJ&dq=dolbeer%20logging%20engine&pg=PA587#v=onepage&q=dolbeer%20logging%20engine&f=false

Ran across the above when conducting research on steam traction engines. Good luck. (CaptianNemo (talk) 04:56, 31 May 2012 (UTC))[reply]

http://familytreemaker.genealogy.com/users/h/o/p/John-E-Hopkins/WEBSITE-0001/UHP-0060.html List's same ship as 1,656 tons. Will try to figure out which is correct. Captian's full name is Charles Lewelyn Dingley. Has a son named Charles Lewelyn Dingley Jr.(CaptianNemo (talk) 21:09, 30 August 2012 (UTC))[reply]

Located 8 different sources and can now start an article on the good captain and the ship. Sources conflict so it may be some time before it hits the web... (CaptianNemo (talk) 22:05, 30 August 2012 (UTC))[reply]

This section is strangely structured and contradictory. It starts "Ericsson then proceeded..." following the previous paragraph saying that he had died. The paragraph on the caloric ship states that the ship was /not/ built in 1852, then goes on to say that the keel was laid in 1852 and it was launched in the same year. Then it switches to future tense. — Preceding unsigned comment added by 203.15.64.15 (talk) 21:45, 20 February 2019 (UTC)[reply]

John Franklin???

[edit]

This sounds more like John Ross (Arctic explorer). Anthony Brandt, "The Man Who Ate His Boots" says that Ericsson and Braithwaite put together the boiler, etc for the Victory. When was Franklin in the Antarctic?Benjamin Trovato (talk) 01:37, 14 December 2012 (UTC)[reply]

Request for Comments

[edit]

There is an RfC on the question of using "Religion: None" vs. "Religion: None (atheist)" in the infobox on this and other similar pages.

The RfC is at Template talk:Infobox person#RfC: Religion infobox entries for individuals that have no religion.

Please help us determine consensus on this issue. --Guy Macon (talk) 05:27, 23 April 2015 (UTC)[reply]

Legacy

[edit]

I have removed the long-standing "Legacy" section which read: "Although none of his inventions created any large industries, he is regarded as one of the most influential mechanical engineers ever and without a doubt the best naval engineer in America in the 19th century.", and the corresponding clause in the lede. There is no source to back this up. A claim of this magnitude absolutely requires at least one source, otherwise it is just the personal opinion of a Wikipedia editor.
