IMPROVEMENTS IN NUT-LOCKS, CHIEFLY DESIGNED FOR USE IN UNITING THE ENDS OF RAILWAY RAILS to be as follows:-
Year: 1884

page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN NUT-LOCKS, CHIEFLY DESIGNED FOR USE
IN UNITING THE ENDS OF RAILWAY RAILS to be as follows:-
"
This invention relates to a nut lock or fastener of simple and inexpensive
construction, the same being easily applied and removed, and when applied reliably
retaining its position, as hereinafter fully set forth.
The improved device comprises a key, which embraces and locks or fastens the
nut, and a washer, having a lip which is bent over the key in such manner as to
prevent the vertical and lateral displacement of the same.
The said key is in the form of a bar, provided with legs or extensions, the inner
sides of which are adapted to embrace the nuts, the outer sides thereof being
inclined or diagonal, so that the widest parts of the legs are below.
The washers have lips which extend diagonally so as to accord with the diagonal
sides of the legs of the key.
When applying the improved nut lock the bolts are first placed in position and
the washers fitted thereon.
The nuts are now screwed on the bolts to the required extent and tightened
against the washers. The key is then placed on the nuts, and the lips of the
washers are bent over the inclined legs of the key so as to overlap the fronts
thereof. The key and legs are thus prevented from moving both upwardly and
outwardly, and the nut is securely locked or fastened.
The washers rest between the heads of the rails and bases thereof, and bear
against one or both of the same, so that they are prevented from rotation and thus
the security of the lock or fastener is assured, the washers being prevented from
becoming displaced by the nuts and the latter by the key. As the legs of the key
are embraced on their sides and fronts by the lips of the washer, the key is reliably
retained on the nuts

page_text: When the nuts or any other parts are to be removed, the lips are bent back so
as to clear the legs of the key whereby the latter may be lifted from the nuts.
The said nuts may then be unscrewed and the washers removed, the bolts then
being free to be withdrawn, and the fish-plate or other bar employed disconnected
from the rails.
While the key is formed of any suitable material, it is designed to construct the
washers of a good quality of metal, which will permit the lips to be bent and
tightened on the keys, and again bent back without breaking or being fractured
during such operations.

page_text: I HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co Patent. Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my invention for "IMPROVEMENTS IN NUTLOCKS CHIEFLY DESIGNED FOR USE
IN UNITING THE ENDS OF RAILWAY-RAILS" and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to a nut-lock or fastener of simple and inexpensive
construction, the same being easily applied and removed, and when applied reliably
retaining its position, as hereinafter fully set forth.
The improved device comprises a key which embraces and locks or fastens the
nuts, and washers having lips which are bent over the key in such manner as to
prevent the vertical and lateral displacement of the same.
In the accompanying drawing
Figure 1 is a side elevation of a nut-lock or fastener embodying this invention
and applied to the bolts of a rail fish plate.
Figure 2 is a longitudinal horizontal section thereof, on the line x x Figure 1.
Figures 3, 4 and 5 are side elevations of details.
Similar letters of reference indicate corresponding parts in the several figurés.
A. A are nuts which are shown as applied to the bolts for securing fish plates to
railway rails, and are locked or fastened by a key B and washers C.
The said key consists of a bar a, provided with legs or extensions b, the inner
sides of which are adapted to embrace the nuts; the outer sides thereof being
inclined or diagonal, as at c, so that the widest parts of the legs are lowest,
The washers C have lips D which extend diagonally so as to correspond with
the diagonal sides of the legs c of the key.
When applying the improved nut lock the bolts are first placed in position and
the washers fitted thereon, it being noticed that at first the lips are not bent over
the legs, see Figure 4.
The nuts are now screwed on the bolts to the required extent and tightened
against the washers. The key is then placed on the nuts, and the lips D of the
washers are bent over the legs of the key so as to overlap the fronts thereof, the
positions of the several parts being shown in Figure 1.
As the lips of the washers are bent over the legs of the key the latter is
prevented from moving both upwardly and outwardly and thus the nuts are
securely locked or fastened.
The washers rest between the heads of the rails and the bases thereof and bear
against one or both of the same, so that they are prevented from rotation, and
thus the security of the lock or fastener is assured; the washers being prevented
from becoming displaced by the nuts, and the latter by the key. As the legs of
the key are embraced on their sides and fronts by the lips of the washer, the key
is reliably retained on the nuts,

page_text: When the nuts or any other parts are to be removed, the lips are bent back so
as to clear the legs of the key so that the latter may then be lifted from the nuts.
The said nuts may then be unscrewed and the washers removed. The bolts can
then be withdrawn, and the fish-plate or other bar employed disconnected from the
rails
While the key is formed of any suitable material, it is designed to construct the
washers of a good quality of metal, which will permit the lips to be tightened on
the keys, and again bent back without breaking or being fractured during such
operation.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is
First. A nut-lock or fastener consisting of washers provided with lips and a
key provided with legs embracing the nuts, the said lips being bent over. the said
legs, substantially as, and for the purpose, set forth.
Second. A nut-lock or fastener having a washer provided with a lip, and a key
provided with a leg, the said lip being adapted to be bent over the said leg,
substantially as, and for the purpose, set forth.
Third. A nut-lock or fastener consisting of washers provided with lips, and a
key provided with legs, the said lips being bent over the said legs and overlapping
the fronts thereof, substantially as, and for the purpose; set forth.
