|William B. Ruger obtained a US
No.D151,719, for the outline of a brace on November 9, 1948, with a
duration of 3-1/2 years. With that degree of protection, three
of brace were made, one marketed under the A.R.T.I.S.A.N
another under Ruger's assignee, the Ruger Corp. of Southport, Conn.,
and the third marketed by the former Seymour Smith & Sons, Inc. of Oakville,
Conn., a distributor of arborist tools. The last of these is
illustrated below as their No.2310.
The chucks used in these braces follow the design of the John A. Leland's US Patent No. 912,582, assigned to the Millers Falls Company. That patent would have run out in 1926, more than twenty years before the Ruger braces illustrated here were made. Therefore, it is hardly a proof of Millers Falls parenthood that the Ruger braces' chucks were patterned after the Leland patent.
|Brace 1: Seymour Smith & Son
version of D151,719:
||William B. Ruger's US Design Patent No. D151,719:
||John A. Leland's US Patent No. 912,582 for the same chuck
used in the Ruger-designed braces:
|The inside of the ratchet isn't worn (49 teeth)
||Parts mostly out:
||The cover is marked, and the selector is, too, although that
can't be seen here. There is an extra part, the shim 2nd from
left. Also, the selector is now a die casting.
|Pawls & springs back in:
||Selector above slot:
|| All back together:
|I could not
resist peeking to see what else might be different in the Seymour Smith
brace's ratchet, considering that the function of the selector is so
much better marked. What I found is that there's an extra part,
the shim that acts as a dust shield below the selector. Also,
even though the selector has a better shape, it's just a die casting
and there's nothing to stop an ignorant user from twisting it.
|Brace 2 - Ruger Corp., Southport, Conn.
||The ratchet design is detailed below. While I was
thinking that the Pat. Pending
marking on Brace 1 referred to the ratchet, I searched the USPTO
website and found countless ratchet patents, none of them remotely like
selector on this brace is unmarked; as a result, when it needed
lubrication, a cluless user tried to loosen it up by rotating with a
crescent wrench, twisting it nearly all the way off. I
administered the coup de gras
in order to take apart, clean & repair the brace. The
function of the selector is clearly marked on the Seymour Smith brace.
The firm is now named Sturm, Ruger, Inc. but is still located in Southport.
|There are 49 ratchet teeth:
||Ratchet parts out:
||The ratchet selector (2nd from left) is broken. The
pawls show no wear at all.
||Here's where the ratchet selector fits (head rotated 180
||Most of the parts are back in now. Note that the teeth
of the pawls meet the ratchet teeth at an angle.
|Brace 3 - A.R.T.I.S.A.N trademark
||Maybe someday I'll cut through the welds and find out what
it is that provoked a user to mutilate this brace ...
|Something must have gone horribly wrong with the ratchet
mechanism of this brace that warranted welding it tightly shut ...
