PREVENTING NUTS, AND BOLTS, FROM WORKING LOOSE
Year: 1884

page_text: WILLIAM MORLEY (Engineer) 65 Walmer Road Plumstead Co of Kent England,
do hereby declare the nature of my invention for PREVENTING NUTS, AND BOLTS,
FROM WORKING LOOSE, to be as follows:-
A Steel Washer as represented by E E' and a Nut grooved as shown by the
sketch, D, and of a Bolt the screwed end of which, shall coincide in section to the
bore of the Washer. The Washer is made a fixture by means of the projection a a¹
which is formed on its under surface, the bore of the Washer is so formed that.
when the screwed end of the Bolt is made to fit it, it prevents the Bolt from
rotating when it is being tightened up, hence the Bolt may be put in a free fit and.
is made a fixture, without the aid of keying, driving, or being held by a spanner.
The grooves 2 2 2 2-in the Nut, D, are in the under surface, radial, to the
centre, and at right angles to the axis. When the Nut tightens on the Washer.
the projection R₁ of the Washer is pressed downward, springing up again, into the
grooves as they come over the projection, hence, the Nut cannot be loosened untill
In the Nut, A,
sufficient force is applied to overcome the resistance of the Washer.
the grooves are altered in form to correspond to the Spring Locking Pin, G.
The Washer B B is formed solid, that is, without a break in the circumference,
A conical hole is formed at, C, into which is pressed the Locking pin G. which has
a projection, H, upon it. .G is drawn clear while the Nut is being tightened,.
when it is screwed down, the Pin G is pushed forward untill the projection H enters
the groove of the Nut, hence, the locking action is secured, the object of this
Washer is to cheapen the cost of production of large Washers, and to give greater
circumferential bearing surface, especially on the bottom face of the Washer.

page_text: WILLIAM MORLEY 65 Walmer Road Plumstead Kent, Engineer, do hereby
declare the nature of my invention for PREVENTING NUTS, AND LIKEWISE BOLTS,
FROM WORKING LOOSE, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My Invention consists of a Steel Washer as represented by the sketch E E¹, and a
Nut grooved as shown by the sketch D, and of a Bolt the screwed end of which shall
coincide in section to the segmental bore of the Washer, the Washer is made a
fixture by means of the projection a a¹, on the under surface of the Washer, the
bore of the Washer is so formed, that when the screwed end of the Bolt is made
to fit it, it, prevents the Bolt from rotating when being tightened up, hence, the
Bolt may have a round, semicircular, or any required shape of head, may be put in
a free fit, and is made a fixture, without the aid of, keying, driving, or being held
by a spanner, the grooves 1111 in the Nut, D, are in the under surface radial to
the centre and at right angles to the axis of the bore, when the Nut tightens on the
Washer the projection R¹ is pressed downward, springing up again into the
grooves as they come over the projection hence, the Nut cannot be loosened untill
sufficient force be applied to overcome the resistance of the Washer. In the Nut, N,
the grooves extend half way across the face and correspond to the projection, H,
on the Lock Pin, G, The Washer, B, B¹, is formed solid, that is, without a break
in the circumference, A conical hole is formed at, C, into which is pressed the
Spring Lock Pin, G, which has a projection, H, upon it, the pin is drawn clear
while the Nut is being screwed down, it is then pushed forward untill the
projection H enters the groove of the Nut, hence, the locking action is secured,
where it is desirable as in machinery in motion to confine the Locking Pin within
the perimeter of the Washer, the Pin may be formed solid as in sketch, L, K, K;
in this case the hole, C, in the Washer will be parallel and the Pin end rivetted
over to retain it in the Washer, when screwing the Nut down the projection, H,
will lay below the upper surface of the Washer, when the Nut is down tight,
H, will be turned up vertically into the groove of the Nut, the width of groove being
slightly in exess of the width of the projection to admit of its doing so, the Nut
will then be slightly unscrewed to prevent, K, from falling down again, hence the
locking action is secured by, K, being pressed against the shoulder of the Washer,
the object of this Washer is to cheapen the cost of construction by the use of some
cheaper material than spring steel, such as malleable iron, or whatever material may
best suit particular cases, and to give greater circumferential bearing surface on
the under face of the Washer. When both the Nut and Bolt are to be locked
the Washer will be formed as described above, when the Nut only the Washer may
be circular in bore, or if segmental in bore and the Bolt already a fixture the
under projection of the Washer may be dispensed with, when the Bolt only is to be
locked the upper projection may be dispensed with. Where no Nut is required
and the Bolt screws into a tapped hole the Washer will be circular in bore and the
Bolt head grooved so that it may be locked as if it were a Nut. 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.
Firstly. A Nut grooved in its under surface, the centre line of each groove being
radial to the centre and at right angles to the axis of the bore, for the purpose
described. Secondly a Washer with locking projections one on the under surface

page_text: to lock the Washer, the other on the upper surface to lock the Nut, and a
segmental bore to lock the Bolt, or with any two of these three devices, as
herein before described, or as modified to suit particular cases. Thirdly a Bolt the
screwed end of which shall coincide with the segmental bore of the Washer for
the purpose described.
