W1714 TO DR. CALVIN BROOKS MCQUESTEN from Samuel A. Duncan
Feb 4 1885
To: Dr. Calvin Brooks McQuesten
From: 32 Park Place, New York City, New York, U.S.A.

Dr. C.B. Mcquesten [sic]

Dear Sir:

I see no reason why the devices you point out in your two letters may not be patented; that is the draw hook and a pivot or bolt therefor constructed as you suggest. This combination is not shown in any of the references given on the search that was made; though in making that search no status was laid upon the bolt being larger at one end than at the other. I don't think you will meet this particular construction in the Patent Office, & so I don't see that we need to make a search upon this point; still it should be done if you wish to be sure (reasonably so) of the success of an application upon it.

I will await your instructions as to proceeding with a search or an application, as you may decide.1

Yours truly

Sam'l. A. Duncan


1 The device under discussion is a train car coupler previously patented by William Dunn and an improvement that he was trying to have patented at the time this letter was written. Isaac had been investing money into Dunn's attempts to sell his patents for several years by this time but had received little or no return due to Dunn's incompetence. For more on this new patent, see W1707, W1711, W1712, W2656, W2667, W1532, W2671, W2675, W1716, W1721, W1741. For more on Dunn, see W2554a.
