COMPLETE SPECIFICATION.
An Improved Nut-lock.
I, HERBERT WILLIAM COLLINS, of Cartwright, County of Selkirk, Province of
Manitoba, Dominion of Canada, Builder, 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:--
My invention relates to improvements in nut and bolt locks.
The object of my invention is to provide a construction of this character in which
the nut will be held securely in position after the locking device has been placed
therein; which is neat and attractive in appearance, durable in construction, simple
and efficient in operation, and which can be made at a low cost.
To these and other ends, my invention consists in the improved construction
and combination of part hereinafter fully described and partícularly pointed out
in the appended claims.
In the drawings in which similar numerals of reference indicate similar parts
in all of the figures.
Figure 1 is a side elevation of a bolt, showing the nut in position thereon, the
locking pin being driven in position.
Figure 2 is a central longitudinal partial section of the same.
Figure 3 is a detail of the locking pin.
Many forms of nut locks have been heretofore provided, but in each of them
there has been some defect or other, generally the great cost of manufacture. In
the present construction however but a minimum number of parts are required
and the cost of construction is therefore brought to a minimum rate.
In the drawings, 1 designates the bolt, and 2 the nut. The bolt is provided with
one or more longitudinally extending slots or recesses 3, which are adapted to
receive the bifurcated ends, 4, of the pin 5, adapted to be passed through suitable
openings 6 formed on the nut 2. The pin is adapted to be passed through
suitable openings 6 formed on the nut 2. The end 5 is bifurcated as shown in
Figure 3, the inner surface of the bifurcated ends being rounded as at 7.
In operating my improved nut and lock, it is necessary only that the nut be
screwed on to the bolt to the proper distance, whereupon the pin 5 is inserted
through the opening 6 which is above the spot or recess 3, and the pin driven into
the slot by a hammer or other suitable means. This driving of the pin inward,
causes the bifurcated ends 4 to be forced laterally up the nut, along the recess or
spot 3 and thus prevent the nut from being turned in any direction.
The advantages of this construction are many, including the ease with which
the parts can be place in position, and the absolute certainty of retaining the
nut in its position.
While I have shown but one slot or recess 3, it is to be understood that I may
use one or more of such slots as may be desired, and also that each side of the nut
may be provided with the open space, instead of the providing of one of the sides
with such openings as shown in the drawings.

page_text: While I have herein shown a preferred form of carrying my invention into effect
yet I do not desire to limit myself to such preferred details of construction, but
claim the right to use any and all modifications thereof which will serve to carry
into effect the objects to be attained by this invention in so far as such modifica-
tions and changes may fall within the spirit and scope of my said invention.
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:
A nut leck, comprising a bolt; a nut: radial openings formed in the sides of
said nut a recess formed longitudinally of said bolt, said recess extending across
the threaded portion of said bolt; and a pin having its ends bifurcated, said pin
being adapted to be driven into one of said radial openings and extend in opposite
directions along said recess, substantially as described.
