Improvements in and relating to Nut and Bolt Looks.
I, ALVIN NELSON WOODARD, a citizen of the United States of America,
residing at 172 Harker Street, in the City of Mansfield, County of Richland and
State of Ohio, United States of America, Manufacturer, 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:-
Reference being made to the accompanying drawing in which:
Figure 1 is a side elevation.
Figure 2 is an end elevation.
Figure 3 is an elevation with the throaded end of the bolt and the sleeve in.
section.
Figure 4 is a perspective view of the sleeve, and
Figure 5 is a developed view of the sleeve.
In the several figures like parts are similarly designated.
It is desirable in all bolt and nut locks to leave the bolt, and especially its
thread, and also the nut, intact; and it is also important, in many cases, that the
bolt or nut locking device shall be capable of removal at pleasure; and it is also
of importance that such a looking device shall have the capacity of adjustability
to compensate for wear..
With these facts in mind, my invention consists of an independent, threadless.
sleeve, provided with a series of spirally arranged holes, and adapted to be slipped
upon the end of a bolt beyond the nut, and be secured to the bolt.and against the
uut by means of a pin passed trausversely through the sleeve and bolt, all as I will
proceed now more particularly to set forth and finally claim.
The bolt a may be of any approved construction, and for the purposes of my
invention is provided with a through-hole b in the outer end of its threaded portion..
o is a uut, also of any approved construction. d is a tubular threadless sleeve, of
slightly greater boro thun the greatest diameter of the bolt so as to be capable of
being slipped over the end of the bolt beyond the nut and to be butted up against
the outer face of the nut. As shown more especially in Figures 1 and 5, this sleeve
is provided with one or more series of holes e arranged on a pitch of a very quick
screw-thread, and suitably spaced to provide for a very great number of adjustments
of the sleeve in order to adapt it to any length of projection of the bolt beyond the
nut. In order to lock the sleeve against the nut, to hold the nut in place and to
prevent the sleeve from turning, the sleeve is turned until two of its opposite holes
are in alignment with the hole b in the bolt, and then a pin or key, is driven
through the sleeve and bolt, and its lower end g is bent over or turned up against
the sleeve in order to retain it in position.
It will be seen that my sleeve may be applied to any kind of nut, without
requiring any special adaptation of nut for co-operation therewith.
As is obvious, the pin or key, is the medium by which the locking of the device
is effected, and hence follows that if the key be removed a change of adjustment
may be effected, and a bolt or nut may be readily removed intact, and replaced, a
new pin being the only additional expense necessary to this end.
I have shown and hereinafter particularly claimed, a sleeve having registering
holes on opposite sides, but I wish to be understood as not limiting my invention to
that construction, for it is obvious that instead of passing the pin entirely through,
it may be simply extended into the bolt, and while I do not consider such a.

page_text: construction as desirable as and prefer the construction where the pin passes entirely
through so as to be capable of having its end turned over, upset, clinched, or
otherwise treated so as to fixedly hold the pin in position, still I mean to include
both constructions in my claims.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim, is :-
1. A nut or bolt lock comprising an independent, threadless sleeve, made and
applied wholly independently of the nut, adapted to encircle a bolt aud butt against
a nut thereon, and having a series of spirally arranged holes, and a pin or key
adapted to be engaged with one of said holes and a hole in the bolt upon which it
is desired to lock the nut, substantially as described.
2. A nut or bolt lock comprising a threadless sleeve made and applied wholly
independently of the nut, and having one or more series of oppositely registering
spirally arranged holes, and a pin or key adapted to be passed through said boles
and a hole in the bolt to which it is applied, substantially as and for the purpose
described.
Dated this Eighteenth day of August 1896.
