Improvements in Nut Locks.
We, DOMINICK SIMON LEGER, of rear 192 Charles Street, Waltham, in the
County of Middlesex and State of Massachusetts, U.S.A., Stone Cutter, ISAAC
WHITE, of 188 Charles Street, Waltham, in the County of Middlesex and State
of Massachusetts, U.S.A. Carpenter, FREDERICK WHITE; of rear of 196 Charles
Street, Waltham, in the County of Middlesex and State of Massachusetts, U.S.A.,
Laborer, and ONESIME SIMON LEGER, of No. 50 Main Street, Moncton, New
Brunswick, Canada, Merchant, 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:
Our invention relates to improvements in nut locks, designed particularly for
use in connection with rail securing bolts or the like, and has for its object the
production of a simple and efficient nut lock by means of which a series of nuts
may be simultaneously locked against rotation, thereby preventing the loosening
of the nuts, due to vibration incidental to the use of such devices, particularly
when employed in railway construction.
To the accomplishment of this object our invention consists in providing a
laterally and longitudinally curved resilient nut lock plate intermediate of a rail
and nut lock, and in securing the nut lock to the nuts and the nut lock plate to
the nut lock, to produce a firm and non-vibrating connection throughout the entire
device.
Referring to the drawings,
Figure 1 is a side elevation of our nut lock applied to the fish joint connecting
the contiguous ends of two rail sections.
Figure 2 is a central longitudinal section on the line 2-2 of Figure 1.
Figure 3 is a transverse section on the line 3-3 of Figure 1.
Figure 4 is a detail perspective view of the nut lock plate, and
Figure 5 is a similar view of the nut lock.
Referring to the figures on the drawings, 1 and 2 indicate the adjacent ends of
two rail sections connected by a fish plate 3. provided with bolt apertures 4
correlative with similar apertures 5 in the rails, and through which project the
threaded ends 7 of rail securing bolts 8. 9 indicates what we will term our nut
lock plate, consisting of a strip of spring material provided with a series of
apertures 10 correlative with the apertures in the fish plate, and slightly curved
laterally and longitudinally for a purpose hereinafter apparent. 11 indicates the
nuts screwed upon the extremities of the bolts 8, and seated in correlatively shaped
apertures 12 in a nut lock 13 secured against the face of the nut lock plate 9, as
by a loop 14 projecting from the nut lock plate and through an aperture 15 in the
nut lock 13. 16 indicates a wedge-shaped pin passed through the loop and designed
by its wedging action to force the nut lock against the nut lock plate. The
resiliency of the nut lock plate will now constantly urge the nut lock against the
pin 16, and will exert a pressure upon the rear sides of the nuts, tending to prevent
all vibration of the parts usually incidental to the use of such devices.
We do not care to limit ourselves to the details of construction herein shown
and described, but reserve for ourselves the right to change, modify and vary such
details as come within the scope of our invention.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
'we claim is :
1. In a device of the character described, the combination with a longitudinally
and laterally curved resilient nut lock plate provided with apertures, of an apertured
nut lock, and means for adjustably securing the nut lock to the nut lock plate,
substantially as specified.
2. In a device of the character described, the combination with a resilient nut
lock plate provided with bolt apertures and longitudinally and laterally curved,
of a nut lock provided with nut apertures and with a loop aperture, a loop projecting
from the nut lock plate and passing through said aperture, and a wedge-shaped pin
passing through said loop and designed to adjustably secure the nut lock plate and
the nut lock, substantially as specified.
Dated this 25th January 1897.
