PROVISIONAL SPECIFICATION.
Improvements in Studs, Bolts or Holdfasts for connecting Chairs to
Sleepers on Railways, also applicable to other Studs or Bolts for
like purposes.
We, JOHN JAMES WHITTAKER POTTER, of Toplocks, Runcorn, Cheshire, Mer-
chant, and SAMUEL JOSEPH PAUL SHAW, of 1, Gambles Road, Thornton-le-Fylde,
Joiner, do hereby declare the nature of our said invention to be as follows;
1
It consists of a stud or bolt as driven into railway sleepers for securing chairs
thereto, with one, two or more grooves or recesses formed in its sides and with
the end or side of such groove nearest the head of the stud or bolt of a gradually
tapering form and the end or side of such groove nearest the free end or point
formed as a sharp angle or shoulder so that after the stud or bolt is driven into
the sleeper the wood surrounding it may sink or expand into such groove and
engaging with the sharp angle, prevent the working loose or accidental removal
of the stud or bolt.
The grooves are by preference longitudinal, but they may be in other positions.
Although chiefly applicable to bolts or studs for railway chair securing pur-
poses may apply my improvements to bolts or studs and the like for other like
purposes where a permanent connection is required, and may be applied to dowels
and similar devices for holding objects of wood together.
Dated this 9th day of November 1898.

Improvements in Studs, Bolts or Holdfasts for connecting Chairs to
Sleepers on Railways, also applicable to other Studs or Bolts for
like purposes.
We, JOHN JAMES WHITTAKER POTTER, of Toplocks, Runcorn, Cheshire, Mer-
chant, and SAMUEL JOSEPH PAUL SILAW, of 1, Gambles Road, Thornton-le-Fylde,
Joiner, 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;-
It consists of a stud or bolt as driven into railway sleepers for securing chairs
thereto, with one or more grooves or recesses formed in its sides and with the end

page_text: or side of such groove nearest the head of the stud or bolt of a gradually tapering
form and the end or side of such groove nearest the free end or point formed has
a sharp angle or shoulder so that after the stud or bolt is driven into the sleeper
the wood surrounding it may sink or expand into such groove and engaging with
the sharp angle prevent the working loose or accidental removal of the stud or
bolt.
In order that our invention may be more readily understood and carried into
practical effect we have annexed hereto a sheet of drawings on which:-
Fig. 1 is a side elevation of a bolt made in accordance with our invention.
Fig. 2 is a cross section of same bolt on line a, b.
Fig. 3 is a part section and part elevation of the bolt in position for securing a
rail chair to its sleeper.
(A) is the bolt stem having longitudinal grooves or recesses (1) which cut
in the shape shown on the drawings or may gradually be tapered at one or both
ends, the object being that when the bolt is driven into a sleeper (C) the wood
surrounding it takes into the grooves as seen in Fig. 3 and filling them prevents
the working loose or accidental removal of the bolt as aforesaid.
The grooves are by preference longitudinal but they may lie in other positions.
Although chiefly applicable to bolts or studs for railway chair securing pur-
poses we may apply our improvements to bolts or studs and the like for other like
purposes where a permanent connection is required and may be applied to dowels
and similar devices for holding objects of wood together.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1: A stud, bolt or holdfast with grooves or recesses formed in its stem, as
and for the purposes set forth.
