PROVISIONAL SPECIFICATION.
Locked Nut and Bolt.
I PERCY HARDING RUSS of Culleenamore in the County of Sligo Ireland,
Oyster Culturist do hereby declare the nature of this invention to be as follows:-
The object of my invention is, to provide a simple and effective means for the
fastening of nuts to bolts, so that when the nut is screwed up to its desired position
it can be so fixed as to be immovable until the locking arrangement is released.
The means whereby I accomplish my object, is to provide a pin made of metal,
of such shape as shall fit a hole drilled or cut in the nut, and the bottom end of
which is shaped to fit a groove made in the bolt. The top of this pin is bent over
to the face of the nut, and the end doubled under, into an aperture or bar made for
that purpose, in or on the nut, thereby securely preventing the possibility of the
pin or nut shifting until the pin is released.
The bolt to be used is provided with one or more grooves for the reception of
the bottom of the pin.

COMPLETE SPECIFICATION.
Locked Nut and Bolt.
I, PERCY HARDING RUSS, of Culleenamore, in the County of Sligo, Ireland,
Oyster Culturist, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of my invention is to provide a simple and effective means for
fastening nuts to bolts, so that when the nut is screwed up to its desired position,
it can be so fixed as to be immovable until the locking arrangement released.
My invention will be best understood by the following description, having
reference to the accompanying drawing, whereon
Fig. 1 shews a bolt and nut in sectional elevation, with the locking device
applied or fitted thereto, according to my said invention. Fig. 2 is an end
view of the bolt and nut shewn at Fig. 1. Fig. 3 is a perspective view of the
locking device detached, and Figs. 4 and 5 shew a nut adapted to the purposes of
my invention.
Similar letters of reference indicate like parts in the several figures.
According to my invention, I provide a pin A. (shewn detached at. Fig. 3) made
of metal of such shape as shall fit a hole drilled or cut in the nut B, and the
bottom end A' of which pin is shaped to fit a groove C made in the bolt D. The
top or extended part A' of this pin A is bent over to the face of the nut B, and the
end of the part A' doubled into an aperture B₁ formed on the top of the nut, as
clearly shewn at Fig. 1; or instead of the part A' entering an aperture, it may be
bent over a projection or bar B' made for that purpose in or on the nut, as shewn
in the perspective view of a nut detached at Fig. 4, and in the sectional view of
same applied at Fig. 5; thereby preventing the possibility of the pin A or nut B
shifting until the said pin A is released.
The bolt to be used is provided with one or several grooves C for the reception
of the bottom A' of the pin A, and such grooves (where several are employed)
may be formed in regular or irregular order around the periphery of the bolt.
By my invention I am enabled to effectually secure the nut to the bolt, and to

page_text: readily release same (by simply withdrawing the locking pin) while such locking
device is readily applicable to any ordinarily constructed or formed bolts and nuts.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed,, I declare that what I
claim is :
1. In locking nuts to bolts, a pin A passing through a hole in the side of the
nut, and entering a groove C, or one of several grooves, in the bolt, in combination
with an extended part or top A' on the pin A, bent over the top of the nut and
entering an aperture B' or bent over a bar B' to secure the pin in place substantially
as and for the purposes herein set forth.
2. In locking nuts to bolts, the pin A having the end A adapted to enter a
groove in the bolt, and a top or extended part. A³, for securing the pin in place by
bending the said part A into an aperture or over a bar on the nut substantially as
described, with particular reference to Fig. 3 of the accompanying drawing.
