Office of the Commissioners of Patents, with his Petition, on the
1st July 1869.-A communication from abroad by Reinhold Boeklin,
of Brooklyn, State of New York, United States of America.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Mechanical Draughtsman, do hereby
declare the nature of the said Invention for "AN IMPROVED MANUFACTURE
OP NAIL OR SPIKE, AND MACHINERY FOR MAKING THE SAME, WHICH MACHINERY IS
APPLICABLE TO THE FORMING OF BOLTS AND SPIKES OF THE ORDINARY CONSTRUCTION,
AND OTHER ARTICLES HAVING SCREW THREADS, AND ALSO TO THE STRAIGHTENING OF
SHAFTS, RODS, AND PIPES," to be as follows:-
The nail or spike which constitutes one of the features of this
Invention has formed on its body a series of detached quick screwed
threads or partial threads, so that on driving by means of a hammer
or other like force said nail or spike home it is turned or rotated, and
the material into which it is driven caused to swell and enter between
the threads and within the spaces which separate them at their ends,
so as to lock or securely hold the nail or spike.
The Invention also includes a method of rolling and pressing screw
threads either of a detached or broken character, as herein-before
referred to, or continuous, as the case may be, on nails or spikes, bolts,

page_text: and other articles by entering the body of the article or rod out of
which it is formed while in a heated state between a pair of rolls
having obliquely disposed grooves on their peripheries, and of an
excentric or gradually closing action, so that said body or rod is kept
rolling and spread out endwise in opposite directions, while the screw
thread or threads is or are being gradually formed on it; or instead
of pair of rolls a single roll suitably grooved on its periphery and a
sliding or excentric side die of curvilinear form and suitably grooved
may be used, the rod or body of the article passing with the roll as
it rotates between it and the die, and independently rotating as it
so passes to form in a gradual and like manner as herein-before described
the screw thread or threads.
Also the Invention includes in machinery for making articles of
the character described a rotating main roll to receive the bar on or
in it lengthwise of its periphery; a stationary side cutter and rotating
cutter block; a grooved additional roll on top of the main roll, and
header for heading the spike, nail, or bolt, while lying in the main
roll, prior to the passage of the article being made between the threading
portion of the main roll and threading die operating in connection
therewith, as herein-before referred to, the body or article being delivered
by the action of a pusher out of the carrying groove in the main roll
when required to roll and press it to form the thread. Likewise the
Invention includes in the place of the stationary cutter and rotating
cutting block a pair of excentrically formed rotating cutters, for cutting
off and pointing the bar to form the bolt, nail, or spike while the latter
is being independently rotated. Such machinery or portions of it may
be used for making various kinds of spiral work, either plain or orna-
mental, and having marks or figures rolled or pressed in it, and by
omitting the threading grooves in the rolls, or roll and sliding, or
excentric side die, and employing a suitable free swinging or other
support. Shafts, rods, and pipes may be straightened by passing them,
for instance, under freedom to independently rotate between the main
roll and concave surface of the excentric or sliding side die along or
over which they are worked by the rotation of the main roll.
