POST OFFICE DEPARTMENT, WASHINGTON. D. C., October 23, 1880.
SEALED PROPOSALS will be received at this Department, until 12 o'clock,
noon, on the 26th day of January, 1881, for furnishing a new kind of
mail locks and keys for the sole and exclusive use of the United States
through registered mails.
As the public exposure and searching examination necessary to
intelligent bidding on any prescribed model of a lock and key would tend
to impair, if not entirely destroy, the further utility of such locks
and keys for the purposes of the mails, the Postmaster General
prescribes no model or sample for bidders, but relies for a selection on
the mechanical skill and ingenuity which a fair competition among
inventors, hereby invited, may develop in samples submitted by them.
Specifications of the conditions and requirements relating to proposals,
samples, contract, etc., as well as forms of proposal, will be furnished
on application by letter to the Second Assistant Postmaster General.
No proposal will be considered unless it shall have been submitted in
accordance with such specification and forms.
The contracts which may be made will be in conformity to the
specifications and the accepted proposal. But the right is, however,
reserved to reject any and all of the proposals.
JAS. N. TYNER, Acting Postmaster General.
