page_text: Improvements in Nut Loeks.
We, FRANCIS M MCCARTEA, Gentleman, and MARY C. LESTER, both of San Juan,
in the County of San Benito and State of California, United States of America,
do hereby declare the nature of this invention 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 generally to nut locks or means for preventing a nut
from working loose upon the bolt The object of the invention is to provide
an exceedingly cheap and simple device which 18 adapted for use upon wooden
structures or non stiuctures, and it is especially adapted for use upon vehicles.
With these objects in view the invention consists essentially in providing
a cylindrical receiving socket or receptacle into which fits the nut or a portion
thereof and having ratchet teeth cut upon the portion entering said socket, a
stout spring encucling the socket and provided with a tooth or pawl extending
into the said socket for the purpose of engaging the ratchet faced notches of the
nut thereby securely locking the nut within the socket, said socket, of course,
being rigidly secured to the structure upon which it is intended to use the nut.
The invention consists also in certain details of construction and novelties of
combination all of which will be fully described hereinafter and pointed out in
the claims
In the drawings forming part of this specification
Fig. 1 is a view showing the practical application of the invention, the device
being construction for use upon wood work, such as vehicles or bridges.
Fig 2 is a detail sectional view of the nut, socket and spring
Fig. 3 is a section on line 3-3 of Fig 2.
Fig 4 18 a perspective view of the nut
Fig. 5 is a perspective view of the locking spring and teeth
Fig 6 is a view of the device complete adapted for use upon metal structures.
In carrying out the invention, we employ a socket or receiving receptacle A,
which is constructed with flanges or plates A1 adapted to be secured to any
character of wood work upon which the bolt and nut are to be used When the
socket is to be used upon metal work, such as railroad rails and the like, ribs A³
are formed upon the under side of the socket which ribs are adapted to engage
notches or recesses cut in the base or fish plate thereby preventing the socket
from turning The bottom of the socket has a central opening through which
the bolt B passes, and at diametrical points are produced openings C and C
through which the pin D and the tooth or pawl D project, said tooth or pawl
being carried upon one end of the spring E essentially semi-circular in shape
and embracing one side of the socket A, the pin or stud D being arranged upon
the opposite end and fitting in the opening C to hold the spring in place The
nut F is formed with a polygonal shaped outer portion F1 and a cylindrical
shaped inner portion F, said portions being separated by means of an annular
flange F. The cylindrical portion F, which enters the socket has a series of
ratchet faced notches 'lor recesses F cut therein, which notches or recesses are

page_text: adapted to be engaged by the tooth or pawl D thereby securing the locking of the
nut within the socket which is made fast as previously described The ratchet
tooth D and the ratchet faced notches F are so ai ranged with reference to each
other that the nut can be screwed upon the bolt and into the socket but cannot
be removed, and whenever it becomes necessary to remove the nut the tooth D
must be forced out of engagement with the ratchet faced notches of the nut by
means of any suitable tool. As soon as this is done the nut can be unscrewed
the same as usual
It will thus be seen that we provide an exceedingly cheap, simple and efficient
construction of nut locks capable of use in connection with both wooden and iron
structures, and one which will not get out of order, and one which is not likely
to be tampered with.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same 18 to be performed we declare that what
we claim 18
1. A nut lock comprising a socket and a nut adapted to fit therein, said nut
having a series of ratchet faced notches or recesses, and a spring carrying a
locking tooth or pawl adapted to engage such nut, substantially as shown and
described
2. A nut lock comprising a socket provided with means to prevent rotation,
a spring embracing the exterior of the socket and provided with a tooth or pawl
projecting through the side of the socket into the interior, and a nut adapted
to fit within the socket and having a portion with a series of ratchet faced
notches or recesses adapted to be engaged by the tooth or pawl carried by the
spring, substantially as described.
3 In a nut lock, the combination with the socket having flanges or plates
integral therewith, a nut having a portion thereof shaped to fit within the socket
said portion having a series of ratchet faced notches and a spring adapted to
embrace the exterior of the socket and having a pin arranged at one end of the
spring and a tooth aanged at the opposite end of the spring and adapted to
pass through an opening in the socket and engage the ratchet faced notches of
the nut, substantially as shown and described.
