I JOHN NICHOLDS LESTER Metal Broker of Goldthorn Hill Penn Fields
Wolverhampton in the County of Stafford do hereby declare the nature of my
invention for IMPROVEMENT IN HORSE SHOE SPIKES to be as follows :-
To facilitate the fixing of Spikes to Horse shoes & to allow of the said spikes being
tightened by further turning when worked loosed without the liability of stripping the
thread or breaking the spike off short at the shoulder.
To effect this I make the screw end of the spike or that part which enters the shoe
in a taper form & without shoulder instead of parallel & with a shoulder as in existing
spikes & to insure uniformity 1 screw these spikes with a taper die specially made for
the purpose I apply the same principal to spikes without screws simply driven into the
shoe.

page_text: I, JOHN NICHOLDS LESTER, Metal Broker, Rose Hill House, Coseley near Bilston
in the County of Stafford, late of Goldthorn Hill, Penn Fields, Wolverhampton, 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:-
The objects of these improvements are to facilitate the fixing of spikes to horse
shoes and to allow of the said spikes being tightened by further turning when
worked loose by wear, without the liability of stripping the thread of the screw, or
breaking the spike off short at the shoulder.
To effect this I make the screw end of the spike or that part which comes
immediately in contact with the outer surface of the shoe in a taper form and without
shoulder, instead of parallel and with a shoulder as in existing spikes. Also to
further strengthen the hold this spike is so made as to fit a horse-shoe when
countersunk in the screw holes.
To insure uniformity I screw these spikes with a taper die.
To more particularly describe my invention I annex drawings in which the letters
and figures of reference correspond with those in the following explanation the same
letters of reference being used to denote the same parts in the drawings, in which
figure 1 represents one form of spike, with the improvement described, showing taper
screw and without usual shoulder; figure 2 represents a similar form of existing spike
showing parallel screw and shoulder; figure 3 represents a horse-shoe of an ordinary
type with holes at c and d for receiving frost spikes; figure 4 represents the same
shoe on line e-f in section. In Figure 1 the screw or that part of the screw marked a
is taper and without a shoulder, instead of being parallel and with a shoulder b as in
the ordinary form shown in figure 2.
When the screw wears or works loose the taper part a admits of the spike being
tightened by further turning or screwing in.
Still further strength may be obtained by countersinking the spike holes in the
shoe, as shown at c and d in figures 3 and 4.
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. The making of horse-shoe spikes without shoulders and with the screw tapered,
substantially as described and illustrated in the accompanying drawings.
2. The countersinking of the tapped holes in horse shoes substantially as and for
the purpose described and illustrated in the accompanying drawings.
