The object of our Invention is to prevent the working loose of the
nuts on the screw bolts used for securing fish plates and other parts of
the permanent way; and our Invention consists in slitting the end of

bolt and a collar or unthreaded nut, the collar or nut being conical or
tapered in the interior, and we expand or open out the bolt as in the

collar held fast.

ascertained in and by the following statement thereof, reference being
had to the accompanying Drawings, that is to say:
The object of our Invention is to prevent the working loose of the
nuts on the screw bolts used for securing fish plates and other parts of
the permanent way; and our Invention consists in slitting the end of
the bolt, so that after the nut has been placed thereon and screwed up
tight the end of the bolt may be expanded or opened by means of a
chisel or other suitable tool being driven into the slit.; the nut is thus
prevented working back.
Figures 1, 2, and 3, of the annexed Drawings represent respectively
in side elevation, plan, and cross section our improved screw bolts
applied for securing a pair of fish plates; Figure 4 is a separate view on
a larger scale of a bolt and nut. It will be seen that the bolts are slit
or split at the end, and that after the nuts have been screwed up tight
the slit ends are opened or expanded by a chisel or otherwise to prevent
the nuts working loose. In some cases we use a bolt which is plain
or unthreaded, as seen in Figure 6, or the slit portion of which is plain
or unthreaded, as seen in Figure 5, and in these cases we employ
respectively a collar or unthreaded nut, as seen in Figure 6, and a
partially threaded nut, as seen in Figure 5, the collar or nut being in
both instances conical or tapered in the interior; and we expand or
open out the bolt as shown, so that a corresponding cone is produced
thereon and the collar or nut is held fast.
In witness whereof, I, the said Louis Sterne, for myself and on
behalf of the said James Godfrey Warner, have hereunto set my
hand and seal, this Twelfth day of July, One thousand eight
hundred and seventy.
