[55] Singer gives this limited description of the first machine, with
detailed improvements for which he was then applying for a patent: "In
my previous machine, to which reference has been made, the bobbin was
carried by the needle-carrier, and hence the motion of the needle had to
be equal to the length of thread required to form the loop, which was
objectionable, as in many instances this range of motion was
unnecessarily long for all other purposes...." Quoted from U.S. patent
8,294 issued to Isaac M. Singer, Aug. 12, 1851. It should be noted that
in some instances there was a considerable lapse of time from the date a
patent application was made until the patent was issued. In this case
the handwritten specifications were dated March 14, 1851, and the formal
Patent Office receipt was dated April 16, 1851.

[56] If a patent was not approved, for any reason, the records were
placed in an "Abandoned File." In 1930 Congress authorized the disposal
of the old "Abandoned Files," requiring them to be kept for twenty years
only. There are no Singer Company records giving an account of the first
patent application.

[57] Its whereabouts was unknown as early as 1908, as stated in the
_Sewing Machine Times_ (Aug. 25, 1908), vol. 18, no. 418. Models of
abandoned patents frequently remained at the Patent Office.
Approximately 76,000 models were ruined in a Patent Office fire in 1877.
In 1908 over 3000 models of abandoned patents were sold at auction.
Either incident could account for the machine's disappearance.
