An Improvement in Nut Locks.
Year: 1897

page_text: An Improvement in Nut Locks.
I, OLIVER IMRAY, of No. 28, Southampton Buildings, Chancery Lane, in the
County of London, Chartered Patent Agent, do hereby declare the nature of this
invention (as communicated to me from abroad by Charles Peckham Ellis, of
Franklin, in the County of Venango and State of Pennsylvania, United States of
America, Merchant,) to be as follows:-
This invention relates to that class of nut locks, in which two or more nuts are
locked in series and themselves carry and support the lock, and it is designed to
afford a simple and effective means for locking the same without injuring the nuts
or parts thereof.
For this purpose bolts being inserted through registering holes in a rail and
fish-plate washers are placed thereon. The lock is then placed in position, its
flange extending outwardly from the rail, and the bolts passing through the holes
in the lock. The nuts being then screwed upon the bolts, the lock is then moved
outwardly so as to bring its flange over the square portion of two adjacent nuts,
and a key or wedge is inserted between the lock and the washers so as to hold the
lock in position and to prevent its withdrawal therefrom. The key or wedge is
preferably of a strip of metal bent to U shape; the thickness of the metal being
sufficient to fit neatly in the space between the washer and lock. The nuts may
be unlocked by removing the key or wedge and then pushing back the lock so as
to disengage its flange from the nuts.
The advantages of my invention are that its parts are few in number and simple
in construction, thereby admitting of a great saving in the original cost, that it
admits readily of unlocking without injury to any of its parts, and that no special
tools nor skill are required in placing it in position or in removing it.

An improvement in Nut Locks.
I, OLIVER IMRAY, of Birkbeck Bank Chambers, Southampton Buildings,
Chancery Lane, in the County of London, Chartered Patent Agent, do hereby
declare the nature of this invention (as communicated to me from abroad by
Charles Peckham Ellis, of Franklin, in the County of Venango and State of
Pennsylvania, United States of America, Merchant,) and in what manner the same

page_text: is to be performed to be particularly described and ascertained in and by the
following statement:-
-
This invention relates to that class of nut locks in which two or more nuts are
locked in series and themselves carry and support the lock, and it is designed to
afford a simple and effective means for locking the same without injuring the nuts
or parts thereof, as I shall describe referring to the accompanying drawings.
Fig. 1 is a side elevation partly broken away; Fig. 2 is a plan; Fig. 3 is a
cross-section on the line III-III of Fig. 2; Figs. 4 and 5 shew respectively the
key and lock detached, and Figs. 6 and 7 are modified forms of the lock. Like
symbols of reference indicate like parts.
The
2 represents the rails, 3 the fish-plate, 4 the bolts with nuts 5 thereon, and
washers Ginterposed between the fish-plate and reduced portions 7 of the nuts.
8 represents the lock riding upon and retained by the parts 7 of the nuts.
parts 7 are of a length not less than the width of the flange of the lock 8, which
flange fits over the flat sides of two adjacent nuts and holds them from turning.
The lock has holes 9 fitting upon the reduced portions of the nuts.
The holes are preferably elongated to permit them to be fitted easily and to
permit of slight lateral movement of the bolts without injury to the lock. 10
represents a wedge key preferably of U shape, as shewn in Fig. 4 which serves to
retain the lock in engagement with the nuts.
In Figs. 6 and 7 are shewn modified forms of the lock.
The operation of the device is as follows: The bolts 4 being inserted through
the holes in the rail 2 and fish-plate 3, washers are placed thereon.
The lock 8 is then placed in position, its flange extending outwards from the
rail, and the bolts passing through the holes 9 in the lock.
The nuts being then screwed upon the bolts with their reduced parts 7 towards
the rail.
The lock is then moved outwards so as to bring its flange over the square portion
of two adjacent nuts, and a wedge key 10 is inserted between the lock and the
washers 6 so as to hold the lock in position.
The key or wedge 10 is preferably of a strip of metal bent to U shape as shewn
in Fig. 4. The nuts may be unlocked by removing the wedge key and then push-
ing back the lock so as to disengage its flange from the nuts.
The advantages of my invention are that its parts are few in number and simple
in construction, thereby allowing great saving in the original cost, and admitting
readily of unlocking without injury to any of its parts.
No special tools nor skill being required in placing it in position or in remov-
ing it.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is: --
1. A nut lock consisting of an angled plate carried upon nuts having reduced
cylindrical portions, and engaging the flats of the nuts laterally, and a removable
wedge key for retaining it in position, substantially as described.
2. In a nut lock, the combination of nuts 5, screwed upon bolts 4 into contact
with washers 6, the angled plate 8 carrièd upon the reduced portion of the nuts
and the wedge key 10 inserted between the lock 8 and the washers 6, substantially
as described.
