PROVISIONAL SPECIFICATION.
An Improved Nut Lock.
I, WILLIAM WILSON HORN, of the Firm of Horn & Son, of 151 Strand, in the
County of London, Patent Agent, do hereby declare the nature of this invention, (a
communication to me from abroad by Thomas C. Harris, of Pleasant Grove, Minnesota
U.S.A., Inventor), to be as follows:-
This invention relates to an "improved nut lock" and has for its object the securing
of the nuts in any position and the prevention of the said nuts working loose.
A plate having circular holes to correspond with the position of the bolts is placed
upon the said bolts, previous to the placing of the nut upon the same.
A second plate
having similarly situated holes is placed over this so that the two plates lie one over
the other with the holes registering with each other. The holes in the second plate
are circular on the inner face, but are counter-sunk from the outer face, such counter-
sink being square, serrated or otherwise shaped, to prevent the nut turning round,
the angles of said nut engaging with the angles of the counter-sunk hole, in such a
manner that it is impossible to move the same. The bottom plate is also provided with
suitable tenons or lugs which pass through holes formed in the second or upper plate,
and are secured by wedges inserted in them or by any other suitable means, thus
preventing the two plates moving with relation to each other.
Dated this 17th day of May 1890.

COMPLETE SPECIFICATION.
An Improved Nut Lock.
I, WILLIAM WILSON HORN, of the firm of Horn & Son, of 151 Strand, London,"
Middlesex, Patent Agent, do hereby declare the nature of this invention, (a com-
munication to me from abroad, by Thomas Carlyle Harris, of Pleasant Grove State.
of Minnesota, United States of America, Inventor) 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 improved nut-locks, the object of the invention being to
provide against all possible accidental displacement of the burrs or nuts employed in
connection with a rail-joint.
To the ends above named the invention consists, essentially, of certain novel con-
structions, arrangements, and combinations of elements to be hereinafter fully described,
and specially pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this
specification, in which similar figures and letters of reference indicate corresponding
parts in all the views.
.
Figure 1 is a side view of a rail-joint, representing the same as it appears when
constructed to embody my improved nut-lock."
Figure 2 is a cross-sectional view on linex of Figure 1.
Figure 3 is a cross-sectional view on line y y of Figure 1.
Figure 4 is an enlarged perspective view of the keys employed in connection with
my_lock, and
Figure 5 is an enlarged view of a portion of the lock proper.
In the drawings, 10 represents an inner fish-plate of ordinary construction, through
which the shanks of the bolts 11 are passed. Upon the outer side of the rails there is
placed a strip 12, formed with two or more outwardly-extending tenons 13 and with a
series of apertures adapted to receive the shanks of the bolts 11. After the bolts 11

page_text: have passed through the fish-plate 10, the webs of the rails to be connected, (which
rails are shown at 20 and 204) and the bores of the strip 12, they are engaged by
nuts 14, and in order that these nuts may be held from turning I provide a locking-
plate 15, that is formed with as many apertures b as there are bolts, the inner portions
of said apertures being circular and the outer sections being of star form, eight or more
points (or any multiple of four) being arranged in regular star series. The ends of
this locking-plate 15 are apertures to receive the tenons 13, the arrangement being
such that after the nuts 14 have been turned approximately home the locking-plate
may be adjusted to position upon the tenons and the outer portions of the nuts
adjusted so that they will rest within the inner circular sections of the locking-plate
apertures, the defining-wall of said inner circular section of such apertures being
shown at c in Figures 2 and 5.
After the parts have been adjusted as above described the nuts 14 are turned so that
they will be brought into register with any set or series of recesses of the outer
sections d of the locking-plate, this adjustment of the nuts being secured by inserting
a wrench between the plate and the strip 12, any proper means being employed to
space the said plate and strip. After the nuts have been properly adjusted the
locking-plate is shifted again to the position in which is shown in the drawings, and
the main keys 16 are passed downward through apertures formed in the ends of the
tenons 13 to hold the locking-plate to place; and in order that the keys 16 may be
held from displacement I aperture their lower ends, such apertures being in the form
of key-hole slots e, as shown best in Figure 3, and through said key-hole slots I pass
auxiliary keys 17, having wards f and heads g, the heads being rectangular by
preference. Then through the vertical section of the key-hole slot e, 1 pass a keeper 18,
the ends of the keeper being bent over, as shown in Figure 4, thus preventing the
turning of the key 17. In this way I obtain an exceedingly secure lock.
I
Any proper arrangement for spiking the plates to the ties may be employed, and 1
desire it to be distinctly understood that although I have illustrated a construction
adapted for use in connection with a joint which extends over three ties, still under
certain circumstances the block might be shortened up so as to be used in connection
with a joint which extends over two ties, in which latter case I would prefer that the
tenons 13 should extend outward from points within the outer bolts—that is, from
points such as those marked i in Figure 1.
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 :
1. In a nut-lock, the locking-plate 15, formed with a series of longitudinally-aligned
apertures, the inner ends c of which are round and the outer ends & angular, sub-
stantially as set forth.
2. In a nut-lock, the plate 12, having bolt-apertures and tenons or lugs 13, and the
locking-plate 15, apertured to receive said tenons or lugs and formed with apertures
registering with the bolt-apertures, and having their inner ends c circular and their
outer or not-receiving portions d angular, and fastenings for securing the plate 15 on
the said tenons or lugs, substantially as set forth.
3. In a nut-lock, the combination, with the inner fish-plate, of an apertured and
tenoned strip 12, a locking strip or plate 15, formed with apertures adapted to receive
the bolts and nuts such apertures being formed with star-shaped sections d and circular
sections c, key 16, which pass through apertures formed in the tenoned ends, and
auxiliary keys 17, which engage the keys 16, substantially as described.
4. In a nut-lock, the combination, with a tenoned strip 12, of a locking-plate
apertured to receive said tenons, keys 16 which pass through apertures formed in the
tenons, and auxiliary keys 17 formed with wards fand keepers 18, substantially as
described.
