Knives with Patents
Re: Knives with Patents
This knife doesn’t have the patent number; it was obviously made before a patent was issued. But I thought it might fit in this thread anyway.
While this knife has been used, typical of an older Schrade, it still has lots of life left in it.
Does anyone know the guidelines of using the Pat. Pend. Stamp?
I have heard that it could only be used of a short period of time. It would date this knife pretty closely if we could find if/when a patent was issued on the 15OT.
Thanks for your help,
Dale

Re: Knives with Patents
Thanks Eric!
Now what does the Pat Pend mean on the tang of my knife & how can it be used to date the knife?
Does that mean it was made after they filed for the patient & before it was granted, approx. late '64 or early '65?
Thanks again,
Dale

Re: Knives with Patents
Knives with patents are one of my favorite things to find. Here's a small display of mine with four German knives whose design patented in 1880.

Re: Knives with Patents
Heres another one that I just got in the mail. It is a spring loaded single blade. I will email it to LT and see if he has info on it. When you slide the top of the case open all the way the blade springs out. Pretty neat little knife 3 1/8" closed. Inside the case is the word PATENT and nothing else.
If anyone elase has seen or has info on it I would appreciate it.
Merry Christmas to all.
Mike

Re: Knives with Patents
Dale,
What is the handle material on the sharpfinger you showed above? Is it the usual delrin or something else? (Pic looks like something different to me)

Re: Knives with Patents
Phil,
That is a 15OT Deerslayer, the big brother of the 152OT Sharpfinger.
The handle is Delrin, but someone has ground the handle down for some reason, perhaps to better fit a non-standard sheath. I am not sure why, but the handle has been ground down. I think that is what makes the Delrin look different, along with the age of the Delrin & the fact that it has not received the best of care at some point in it's life.

Re: Knives with Patents
I emailed pictures and a description to LT and this was his response.
I have seen variations on your knife usually european . Nice variation of oddball mouse trap mech. There are several variations. When you see PATENT like that it is usually Euro. Nice find I love oddball stuff. LT
I will try and find out who held the patent.

I've come into this one since this thread started, not a patent knife but a Brit equivalent.edgy46 wrote:It is listed as a dog grooming blade remington patern R4733 in Stewart&Ritchie Remington knives past and present pg. 162
Probably made in Sheffield, Tang stamped Spratts, England. Well known (in the UK ) as pet food and accessories suppliers

Re: Knives with Patents
Here's a salesaman's sample knife with clear green handles that show the Mastercraft knives that Robeson made.
Re: Knives with Patents
I used to have an Allen Cut. Co knife that had a patent on it.
I have photos, but the knife went to join family.

Re: Knives with Patents
I thought that I would revive this thread since I picked up another patented knife that I thought was really cool. It is marked SCHMACHTENBERG BROTHERS on the front tang of the main blade, which is deep etched SILVER KING. The pen blade has PATENT 449,449. The knife has what I think are pewter bolsters and the backspring is covered with brass. Small blade has GERMANY on the back tang. I usually don't buy German made knives but had to have this one. It's 3 5/8" closed.
Also posted is a Rare Joseph Rodgers round knife with a patent number of 7678 deep etched on the main blade. In order to open the blades you need to align the round rings till you find the opening which allows you to open and claose the blades. It has horn handles and is 3 1/2" closed.
The last one does not have a patent mark on it but have seen some like it that do. It is a folding manicure set that came in a leather pouch.
Any help on the patent for the first knife would be appreciated.
Mike

Re: Knives with Patents
Here's my contribution. There is an English patents list but I'm not sure where mine falls into it since they started renumbering but I think this patent dates to the late 1700's early 1800's.
I measure my collection by the ton.

Re: Knives with Patents
It's not a switch blade. It looks like a traditional lock back except the knob at the butt engages the back spring. As long as the knob is engaged it opens like a normal knife but won't close. Disengage the knob and then push on the back spring like a normal lock back and you can close the knife. It looks like it was designed so that if you knew you weren't going to use it for a long period of time you could leave the spring disengaged. It looks like around 1/4'' or so of the tip is missing and it has been reground but I suspect it falls into the category of a gentleman's self defense knife which were popular around that time. The scales are snakeskin pattern bone but worn. It's definitely an old one.

Re: Knives with Patents
Here is a JACK KNIFE BEN with PAT'D 4/7/08 and I have a WINCHESTER with the same double fluted punch blade with the same tang stamp. Now if I could find a NAPANOCH cattle knife with the same punch & markings?

Re: Knives with Patents
Robeson had many patents through the years.
I do not have an example of all of them, I don't think.
I probably cannot even present a coherent listing of them or pictures.
Michael mentioned the MasterCraft knives previously in this thread. Robeson introduced the line in 1929.
They also patented a handle/liner arrangement where the nickel-silver liners wrapped over and around the edges of the composite handle material, holding them in place and negating the need for handle pins. Patented 6/13/1916.
Below are photos of several examples of such knives and a tang stamp of the patent date. All but the fancy slant bolstered congress are mine. The congress was an Ebay auction knife from which I snipped the photos. It's a small photo. You cannot tell much from it. That is the only example of that pattern I have ever seen.
Of course, Robeson held the patent for the Cooper punch blade, dated APR 25, 05.
They made the Flame Edge tungsten-carbide coated knives in the 1950's and the Frozen Heat tempered knives from the same time period.

Re: Knives with Patents
This is the only one I have with a patent no. for the liner-lock. This old Catt was etched Hunters Pride at one time if I recall correctly. Lost my books in a house fire. Its got some blade wear as you can see but my pics don't do justice to that beautiful old bone. Slim.

Thank's Miller Bro's. Except for in books I've only seen a few old Catt hunters at shows. The large ones usually have a very large number after the dollar sign. Slim.
