page_text: I, WILLIAM CLARK, of the firm of A. M. and Wm. Clark, of 53, Chancery
Lane, in the County of Middlesex, Fellow of the Institute of Patent Agents,
do hereby declare the nature of this Invention (a cominunication to me from
abroad by James William Morton, of Orange Court House, State of Virginia,
United States of America, Lawyer) to be as follows:-
:-
The object of this invention is to produce a device by the use of which nuts may
be retained securely in position to bind or secure in place the object to which they
they are applied in such a manner as to render it impossible for them to loosen or
work off by shaking or jarring or by any movement incident to its position.
With these objects in view the invention consists of a thread or its equivalent
with which the thread of the nut engages so arranged as to support the nut when
the latter is in position, the said thread being capable of revolving freely upon the
bolt or the like to which it is attached carrying the nut with it, and also capable
of being prevented from turning when desired, in order that the nut may be
turned independent thereof in order to change their relative positions.
The blank from which the bolt is made is provided with a reduced neck and
upon this neck is placed a sleeve which is provided upon its exterior surface with
screw threads or other suitable means for retaining the nut in position. The sleeve
is of a diameter to allow it to revolve freely upon the bolt and it is retained in
position thereon by a button placed upon the end of the bolt, which button may
be formed by simply "heading up" the bolt or may be an independent piece placed
upon the bolt and secured by riveting, a screw thread or the like. To get the best
results in the operation of the device, I supply the space between the interior of
the sleeve and the reduced neck of the bolt with a lubricant, to insure its ready
turning when force is exerted tending to produce that result.
In order that the sleeve may be held stationary when it is desired to turn the
bolt independent thereof, I provide the neck of the bolt with one or more holes
passing therethrough from points diametrically opposite in the circumference.thereof,
and I also provide the sleeve with correspondingly arranged holes so that the holes
respectively, in the neck and sleeve may be brought to register with each other, and
Pri

to extend through the bolt and a short distance into the shell carrying the thread,
but not long enough to project and impede the progress of the nut when being
screwed on.
A convenient means limiting the inward movement of the nut is provided by
making that part of the bolt adjacent to the sleeve of a diameter slightly greater
than that of the sleeve so that as soon as the thread upon the interior of the nut
comes in contact with the bolt, its movement in that direction is checked.
it
It frequently happens that by reason of the wear of the parts or other cause,
is desirable to screw the nut to bring it farther inward towards the object to which
it is applied.
Therefore I form the rear part of the nut with an opening adapting it to receive
the contiguous portion of the bolt, so that the nut is capable of being carried
inwardly a distance equal to the length of this opening.
From the foregoing it will be apparent that when the nut is screwed into its
proper position upon the sleeve, and the pin which holds the said sleeve in position
to receive it is removed, any jarring & of the bolt will turn the sleeve carrying
the nut with it and the latter will not receive any motion independent of the
sleeve. Consequently the position of the nut in relation to the body to which it is
applied is not changed.

page_text: I, WILLIAM CLARK, of the firm of A. M. and Wm. Clark, of 53, Chancery
Lane, in the County of Middlesex, Fellow of the Institute of Patent Agents,
do liereby declare the nature of this Invention (a communication. to me from
abroad by James William Morton (Lawyer) of Orange Court-House Virginia
United States of America) 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 certain new and useful improvements in devices for
locking nuts against turning or becoming displaced by jarring etc..
The object of the Invention is to produce a device by the use of which nuts may
be retained securely in position to bind or secure in place the object to which they
are applied in such a manner as to render it impossible for them to loosen or work
off by shaking or jarring or by any movement incident to its position.
With these objects in view, the Invention consists of a thread or its equivalent
with which the thread of the nut engages, so arranged as to support the nut when
the latter is in position, the said thread being capable of revolving freely upon the
bolt or the like to which it is attached carrying the nut with it and also capable
of being prevented from turning when desired in order that the nut may be turned
independent thereof in order to change their relative positions.
In order that it may be clear how the Invention may be applied and successfully
operated I will now proceed to describe what is considered the best means of
carrying the idea into effect in connection with the accompanying drawings in
which figure 1 is a central longitudinal vertical section of the device. as it appears
in its normal position; figure 2 is a detail view of the blank used to form the
peculiar form of bolt necessary to the Invention; and figure 3. is a detail of the
said bolt in its completed form showing the movable thread in position:
:
In the drawings A represents the main portion of the bolt and B represents the
movable sleeve upon which the nut is placed: The blank from which the bolt is
made is provided with the reduced neck b and upon this neck is placed the
sleeve B which, is provided upon its exterior surface with screw-threads or other
suitable means for retaining the nut in position as shown. The sleeve is of a
diameter to allow it to revolve freely upon the bolt and it is retained in position
thereon by a button c placed upon the end of the bolt which button may be formned
by simply "heading up" the bolt, or may be an independent piece placed upon the
bolt and secured by rivetting a screw thread, or the like. To get the best results
in the operation of the device I supply the space between the interior of the sleeve
and the reduced neck of the bolt with a lubricant to insure its ready turning when
force is exerted tending to produce that result.
In order that the sleeve may be held stationary when it is desired to turn the
bolt independent thereof, I provide the neck of the bolt with one or more holes
passing therethrough from points diametrically opposite in the circumference thereof,
and I also provide the sleeve with correspondingly arranged holes, so that the holes
respectively in the neck and sleeve may be brought to register with each other and
a pin inserted to render the sleeve stationary. The pin used should be of a length

page_text: to extend through the bolt and a short distance into the shell carrying the thread
but not long enough to project and impede the progress of the nut when being
screwed on.
A convenient means limiting the inward movement of the nut is provided by
making that part of the bolt adjacent to the sleeve of a diameter slightly greater
than that of the sleeve, so that as soon as the thread upon the interior of the nut
comes in contact with the bolt its movement in that direction is checked.
It frequently happens that by reason of the wear of the parts or other cause it
is desirable to screw the nut to bring it farther inward towards the object to which
it is applied. Therefore, I form the rear part of the nut with an opening adapting
it to receive the contiguous portion of the bolt so that the nut is capable of being
carried inwardly a distance equal to the length of this opening.
From the foregoing it will be apparent that when the, nut is screwed into its
proper position on the sleeve and the pin which holds the said sleeve in position
to receive it is removed any jarring etc of the bolt will turn the sleeve carrying
the nut with it and the latter will not receive any motion independent of the sleeve.
Consequently the position of the nut in relation to the body to which it is applied
is not changed.
Iri
Although I have particularly described the precise construction of the respective
parts employed in the device, I do not of course wish to be understood as limiting
myself thereby as many modifications may be made without departing from the
spirit of the Invention.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what
I claim is
1. As a means for retaining a nut against moving longitudinally upon the bolt
to which it is attached, a freely revolving sleeve mounted upon the bolt and
carrying the nut as described.
2. As a means for retaining a nut against moving longitudinally upon the bolt
to which it is attached, a freely revolving sleeve mounted upon the bolt retained
thereon by an enlargement upon the end of the said bolt, the nut being carried by
the sleeve, substantially as described.
3. As a means for retaining a nut against moving longitudinally independent of
the bolt to which it is attached, a bolt provided with a freely revolving screw-
threaded sleeve by which the nut is carried the said bolt and sleeve being provided
with registering holes for the reception of a pin to hold the sleeve while the nut is
screwed thereon.
