PROVISIONAL SPEITIATION.
An Improved Washer, particularly applicable for the Permanent
Way of Railways.
I, EDWARD NELSON, Superintendent of the Permanent Way, Furness Railway
Company, Barrow in Furness, Lancashire, do hereby declare the nature of this
invention to be as follows:-
My improved washer is not applicable for single bolts but is only intended for
use where there are two or more adjacent bolts as for instance on the fish plates of
the permanent way of railways and the object of my invention is to lock in a simple
and inexpensive manner the nuts on the bolts so that they cannot unscrew by
vibration.
My improved washer consists of a plate of sheet or other metal with two or more
circular portions punched with a central hole, one for each bolt. The circular
portions are connected by a narrow strip of the metal or by more than one strip if
intended for more than two bolts and each circular portion has a projection or
projections, preferably two projections, at right angles to the connecting strip or
strips.
When the washer is laid upon the bolts and the nuts are screwed down, one of
the projections is turned up against one edge of each nut and from the peculiar
construction of the washer it is quite impossible for the nut of either bolt to
turn in either direction after it has been secured in the manner described.

COMPLETE SPECIFICATION.
An Improved Washer, particularly applicable for the Permanent
Way of Railways.
I, EDWARD NELSON, Superintendent of the Permanent Way, Furness Railway
Company, Barrow in Furness, Lancashire, 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 :-
My improved washer is not applicable for single bolts but is only intended for
use where there are two or more adjacent bolts as for instance on the fish plates of
the permanent way of railways and the object of my invention is to lock in a simple
and inexpensive manner the nuts on the bolts so that they cannot unscrew by
vibration.
My improved washer consists of a plate of sheet or other metal with two or more
circular portions punched with a central hole, one for each bolt. The circular
portions are connected by a narrow strip of the metal or by more than one strip if
intended for more than two bolts and each circular portion has a projection or
projections, preferably two projections, at right angles to the connecting strip or
strips.
When the washer is laid upon the bolts and the nuts are screwed down, one of
the projections is turned up against one edge of each nut and from the peculiar
construction of the washer it is quite impossible for the nut of either bolt to turn in
either direction after it has been secured in the manner described.
And in order that my invention may be fully understood and readily carried into

page_text: effect I will describe the accompanying sheet of drawings reference being had to the
figures and letters marked thereon.
Fig. 1 represents two views of a washer made according to my invention.
Fig. 2 represents three views of the same with two of its lips turned up as would
be the case when applied to two bolts and
Figs. 3 and 4 represent a side view and sectional end view of the adjacent ends of
two railway rails with the connecting fish plates and bolts to the latter of which
my improved washers are shown applied.
s
The complete washer A is punched or stamped out of a single piece of metal
such as mild sheet steel and consists of the collars or washers a' connected together
by the strip a² and each furnished with a projection or lip a³, preferably two
projections or lips for each collar a¹ at right angles to the connecting strip a².
In Fig. 2 the two lips a³ on the same side of the strip a² are shown turned up as
they would be in actual use.
Figs. 3 and 4 represent a portion of two adjoining railway rails b and the usual
fish plates and bolts e and e² passed through the same to connect them together.
Upon each pair of bolts e or el is placed one of my improved washers A and one of
the lips a³ is turned up against the one side of each nut as shown.
It will be evident that the connecting portion a² of the washer renders it quite
impossible for the collars or washers a' to turn or move from their positions and the
turned up projections a3 bearing against the sides of the nuts will effectually
prevent the nuts from turning and working loose.
The second or lower set of projections as on the washer A can be used if the first
should get broken or damaged.
My improved washer can be applied to the heads of steam cylinders and for
other purposes where two or more adjacent bolts require to have their nuts locked
effectively.
To unscrew a nut it is obviously necessary to first bend back the turned up
projection a³ which bears against it.
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-
A washer composed of one piece of metal punched for two or more bolts and
provided with lips or projections for locking the nuts of the bolts substantially in
the manner and for the purposes described and as illustrated by the accompanying
drawing.
Dated this 3rd day of November 1891.
