COMPLETE SPECIFICATION.
Improvements in and connected with Nuts.
I, ROBERT EDWARD PHILLIPS, Assoc. M. Inst. C.E., M.I.Mech. E., of 70, Chancery
Lane, in the Parish of St. Andrews, Holborn, in the County of Middlesex, Con-
sulting Engineer & Chartered Patent Agent, do hereby declare the nature of this
invention (which has been communicated to me from abroad by Eugene David
Boasso, Carriage and Wagon Maker of Charenton, St. Mary Parish, Louisiana,
U.S.A., Albert Mansfield Cotten, Lumber Merchant, of Morgan City, Louisiana,
U.S.A., and Arthur Henry Angelloz, Merchant, of St. Martinville, St. Martin
Parish, Louisiana, U.S.A.) 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 improvements in nut locks, and consists of certain
novel constructions, which will be hereinafter more particularly set forth and
claimed.
In the accompanying drawings forming part of this specification,
Figure 1 represents a perspective view of the nut lock embodying my invention.
Figure 2 represents a similar view of the same applied to the fish plate bolt of
a rail with the nut in position.
Figure 3 represents a central vertical section through the devices illustrated in
Figure 2, and
Figure 4 is a view of a modified form of my invention.
nut 2.
1 in the drawings represents the bolt, 2 the nut mounted upon the same, and 3
my improved nut lock. This latter comprises a body portion 4, preferably hex-
agonal in shape and formed with a similar shaped recess 5 adapted to receive the
Said body portion 4 is further provided with a central aperture 6 adapted
for the passage of the bolt 1 therethrough. A weight 7 of any desired outline
preferably having a plane or flat lower surface with half round ends, is secured
to the bottom of the body portion, 4, so as to prevent any rotation of the latter
without lifting said weight.
When my improved lock is to be applied in position, the same is first slipped on
to the bolt before the nut is applied. The nut is then screwed into position until
it can no longer be rotated independently of the nut lock. The lock is then moved
forward so that the nut enters the recess 5 and said nut and lock rotated together
until the nut has become sufficiently tight. It will be observed from the above,
that any rotation of the nut will tend to move the weight 7 either to one side or
the other. The gravity of said weight 7 will thus effectually prevent any rotation
of the nut lock and the nut rigidly held in the recess 5. There is no danger of the
nut lock slipping from the nut, as the latter lies in the recess 5 with the body
portion surrounding the aperture 6 lying between it and the plate against which
the nut is being bolted.
This nut lock is particularly applicable to the fish plates of railways, as the
constant jarring and shaking of the bolts tends to loosen the nuts, but with my
improved lock such loosening becomes impossible as the jarring action is not
sufficient to overcome the weight 7, which necessarily follows the rotation of the
nut. The lock is simple and cheap in construction but at the same time very

page_text: effective, as when once applied in position it 'insures against any accidental rotation
of the nut, but at the same time may be instantly detached by applying a wrench
to the body portion and unscrewing the nut and lock together.
While the foregoing description comprehends what is perhaps the preferable
embodiment of my invention, it is obvious that the simplest embodiment thereof
would be a nut having a depending weight as illustrated in Figure 4, designed to
prevent its casual 'rotation.
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: —
The combination with a bolt and nut, of a nut lock comprising a body provided
in its outer side with a recess conforming in shape and dimensions to and adapted
to receive a nut so that the nut will be completely surrounded and enclosed, the
inner side of the lock being closed with the exception of a round bolt opening
communicating with said recess, and a weight connected to the body and having
a plane or flat lower surface with half round ends, the closed side of the lock
being designed to be clamped between the nut and the object through which the
bolt passes, substantially as described
Doted this 8th day of September 1898.
