Yale & Towne Cast Bronze Pin-tumbler Padlocks - 800 Series Models - Manufacture Date?
I am wondering if anyone knows when Yale started producing their cast bronze, pin-tumbler padlocks of the 800 Series (such as the 830, 840, 850, etc. models)?
I can find them in the 1908 Yale catalog but not in the 1893 catalog (I do not have any catalogs for years in between these). I have looked for patents and searched this forum unsuccessfully for an answer.
Based on their build characteristics, I am guessing that they started being manufactured sometime after January 1901 when the patent application for the locking of the heel and toe of the shackle was filed (Patent #US685289) and before the spring of 1908 when the catalog was published. The Yale Paracentric key with the round bow and Y&T trefoil design (Patent #USD29786) seems to be the earliest key design associated with this series of padlocks.
If someone on this forum could help me find the answer to this question I would appreciate it.
Thank You,
Tom

The oldest example of this lock type that I have has the following imprinted into the top where it normally says “super pin tumbler”: “PATENTED AUG 11, 1891, SEPT 8, 1896, OTHERS PENDING”.

That is one of the reasons that I started this thread; I am interested in finding out the year that Y&T began this series and if those locks with the "Patented..." information represent the oldest variation of this series.
If someone knew the year that manufacture began for this series then I thought I could concentrate a search for a Yale catalog and print ads as close to that year as possible to help answer that question.
The "Super Pin..." stamping shows up sometime around 1930. The 1908 Yale catalog suggests the top of the lock in this series was blank with a numbered keyway or the word "YALE" on the keyway (numbered keyways seem to show up randomly in the later build styles of this series). In 1917, a blank top and an unmarked keyway; the 1921 catalog suggests the tops of the padlocks contained stamped text. Sometime from 1925-1929, Yale started adding stamped text to the shackle (but then well into the '30s & '40s some years have plain shackles).
So for a number of the early years (10-15?), this series had a blank top. If the "Patent..." stamping represents the earliest variation, it would seem that they were produced prior to 1908 (the other choice would be around 1921 it seems). The Yale paracentric key with the "Y&T" trefoil on the reverse side of the bow was phased out by Yale by 1915 or earlier.
Does anyone happen to have a photo of a Yale 800 series padlock that has an original key with it that they could share?
Thanks to all for the additional information.

"Does anyone happen to have a photo of a Yale 800 series padlock that has an original key with it that they could share?"
That should have read: "Does anyone happen to have a photo of a Yale 800 series padlock with the "Patented..." stamp on top that has an original key with it that they could share?"
