W1721 TO DR CALVIN BROOKS MCQUESTEN from R.F. Gaylord
Feb 20 1885
From: 32 Park Place, New York City
My Dear Sir:
I enclose specification & assignment of car coupler herewith. Have the petition oath & specification signed where I have marked "U D" & have a notary verify it & place his seal on the same. It is not necessary to have the signature to assignment verified, one or two witnesses may be properly had however.1
[to] Dr. C.B. McQuesten
1 William Dunn had been attempting to patent an improvement on train car couplers (W1707, W1711, W1712, W2656, W2667, W1532, W2671, W2675, W1714, W1716, W1741). Calvin Brook's brother, Isaac McQuesten, had been investing money in Dunn's efforts to sell his other patents and machinery, but had received little return due to Dunn's incompetent handling of the business. For more on Dunn, see W2554a.
