Improvements in Nails for Securing Railway Chairs or Railway
Rails to Wooden Sleepers, and for other purposes, and Apparatus
for Withdrawing the same.
A communication by VILKO MOSKOVICZ, of Agram, in the Empire of Austria,
Merchant.
I, THOMAS PRESCOTT, of 53 Arcade Chambers, St. Mary's Gate, Manchester,
in the County of Lancaster Patent Agent and Mechanical Engineer, 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 to the construction of nails primarily for use in securing
railway chairs or railway rails to wooden sleepers, and apparatus for withdrawing
the same, but said nails and apparatus may also be employed in railway wagon
building and general carpentry where nails are required to be clamped.
In the accompanying drawing illustrating my invention,
Fig. 1 is a side view of a nail constructed according to my invention: Fig. is
an edge view of the same;
Fig. 3 represents my invention applied:
Fig. 4 is a side view of an appliance for withdrawing the nail from the wood :
Fig. 5 represents the application of said appliance.
In
In the several views shown on the drawing similar letters refer to similar parts.
In this invention I form a split nail by constructing a nail as a with a slit b
formed therein, said slit terminating at the inner end in a hole c: The opposite
end of the slit, at the end of the nail is either curved or bent out to a small
extent: The head a' of the nail may be of any shape to suit requirements:
applying my invention a hole is first bored into the wood of about the same depth
as the distance between the hole c and the underside of the head a¹ of the nail:
The nail is then driven in when, the divided parts of the lower portion of the nail
will diverge and enter the wood in a curved form as represented in Fig. 3:
hole c will prevent the slit b extending: By these means the nail cannot become
loose either from the wood drying, malicious tampering, or from other causes.
The hereinbefore described nail may be formed from either round or rectangular
metal rods.
The
Fig. 4 represents an appliance for withdrawing the aforesaid nails when necessary,
and consists of a handle bar as d with a claw end d¹: A sliding bar or rest e is
connected therewith by means of the band clips f and f¹: to the upper end of said
sliding bar a handle g with ratchet teeth g' formed thereon is attached by means
of a joint : the aforesaid sliding bar e is retained in a position relatively with
the bar d by means of a shackle that is connected to the bar d and into which
the handle y is inserted, the teeth g¹ on said handle being kept in contact with the
aforesaid shackle; by means of a spring as k.
In order to withdraw a nail from a wooden sleeper or other use in which said
nail may have been employed the claw end d' of the bar d is placed under the
head a of the nail and the sliding bar e lowered as represented in Fig. 5. The
upper end of the bar d is then grasped by the hand and pulled over in a direction
contrary to the nail: the end e¹ of the bar e which is prevented from rising by the
shackle will act as a fulcrum, and the nail will be withdrawn in the manner shown
by dotted lines in Fig. 5 on drawing.

page_text: Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed, I declare that what
I claim is
terminating
1st. The construction and application of nails in which is a slit as
at the inner end of said slit in a hole c and with points capable of diverging at the
opposite end or extremity of said nails in the manner and for the purpose
substantially as herein before described.
2nd. The construction and application of a split nail in the manner and for the
purpose substantially as herein before described.
3rd. In combination with split or other nails the construction and use of an
appliance for withdrawing said nails from wood substantially as herein before
-described.
Dated this 12th day of July 1895.
