What '02-03 engines used spin-off filters?
Engine Specialty Tools
- Thread starter Ayrhead
- Start date
I found this online… the one on the left looks like for jar opening and the one on the the right seems to be for piston ring compression…

I asked that question online and this was the response… so I will modify my original post…

invented in 1922 by Ernest John Sweetland[3] and George H. Greenhalgh,[1] was standard equipment on early 1920s Chrysler automobiles after being launched on the Chrysler Six.[2] The name Purolator was a portmanteau of pure oil late
The first thing the Purolator filter sales rep says when he starts his "training seminar" pitch to a room full of auto parts countermen is "Purolator invented the oil filter."
But that didn't happen until the 1920s.
patent 693353 looks like a likely possibility, although you should also look at
patent 742238 as well - and check Stan's notes at the bottom.
Wolverine / Wolverine Supply Co., Pittsburgh, PA / jar wrench / patent 742238 Oct 27 1903 Alfred Roesch /
Note that Clara L. Roesch is a witness on patent 693353 - I haven't found any documentation on her yet. She also shows up as witness on 742238 as "C.L. Roesch". Too coincidental for there not to have been some connection.
James B. Irwin of Milwaukee, Wisconsin also happens to be the name of a NASA astronaut, which kind of complicates the search.
I cannot clearly make out the patent date stamped on the other piece.

How about this one, by the same guy
US Patent: 700,752 - Cover Wrench
US patent 700,752 Cover Wrench was issued to James B. Erwin of Milwaukee, WI. It was granted on 05/27/1902. A spring wire loop is compressed by pliers type handles as shown in the drawing. The tool is marked only with the patent date. The handles are frequ
www.datamp.org
Where did 1903 come from.?
The one patent date is : Feb 11, 1902. So that is the one with the wider band which was thought to be a piston ring compression tool… I’ll look to see if I can get a better date on the one with the thin wire band…

patent 742238 Oct 27 1903 Alfred Roesch
"The patent is described as an improvement on James B. Erwin's Feb. 11, 1902 patent (no. 693,353)"
check ALL the photos on ALL the patents at datamp.org
note that Clara is a witness on 700752 as well. WAY too much coincidence for there not to have been some sort of connection between Roesch and Erwin.

I saw May and 2?, and the patent I linked above is May 27, 1902, thus my question on 1903

Our friends at Worthpoint, while they are an invaluable source of information, are less concerned about getting all the I's dotted and all the T's crossed. The item descriptions on Worthpoint can sometimes be misleading, simply because the seller didn't do all the homework.
Here we have a New Britain model P201 piston ring groove cleaner (patent 2124757) - assigned to Aircraft Specialties, Lapeer, MI
The item at bottom is a pair of Duro-Chrome model 2015 brake spring pliers, manufactured prior to 1948 - note the lack of the little widget on the end of the handle used to grab ahold of the hold-down spring.
The other item is a jar wrench - according to datamp.org manufactured by Wolverine:
Wolverine / Wolverine Supply Co., Pittsburgh, PA / jar wrench / patent 742238 Oct 27 1903 Alfred Roesch /
but as noted above, that patent is "an improvement ON 693353.
The other item is a can opener (aka "church key") which could have been made by any number of companies, patents on which were issued to Henry Vaughan (Vaughan Novelty) and American Can Corporation.
the patent drawing for 700752 does not show the band going all the way around the circumfrence,

I’ve cleaned up the date portion on the thin wire grip and it looks like May 27, 1902… no 1903.

May 27 1902 is patent 700752 issued to Erwin
May 27 1903 was a Wednesday and could not be the patent date.
So... "Cover wrench" and "Jar wrench" are being used interchangeably.

Remember that Worthpoint doesn’t supply any of this info, they are simply scraping eBay, and charging you to see old prices. Since eBay doesn’t keep stuff online for long is where Worthpoint is valuable for saving the description.
I suspect if you found a really brain dead eBay post from a while back, it may be on Worthpoint too.

Exactly. I finally figured out that the text you are reading on a "Worthpoint" item is what the person selling the item conjured up. Most of the time the information is accurate. I've run into several where the information was wildly inaccurate (Landers Frary & Clark "canteen", for one.)
I use it quite a bit for identifying stuff, but sometimes it's maddening.
I had over 30 browser windows opened last night trying to sort these patents out, so some of what I've posted above may be a bit confused.
That’s commendable as I have enough issues with just one browser window open. Thanks again for your help with the patents and identifying the tools. This is a Great Site.

^ No problem. Can openers, jar wrenches, lid lifters, and corkscrews are particularly fascinating.
Unlike wrenches, pliers, and screwdrivers, devices used for opening containers of food or drinks are ubiquitous - they're found in every home on the planet - in infinite varieties.
Some of the attempts made between about 1880 and 1920 in these genres are quite interesting - some of them hilarious - some quite frightening.
And in spite of all the gadgetry invented for removing lids from jars, my mother still insists on having a pair of 10-inch slip joint pliers on her marble kitchen counter.
