PROVISIONAL SPECIFICATION.
An Improved Spring Bolt or Fastening for Chains and the like.
VICTOR ALBERT, Jeweller, Conway Road, Colwyn Bay,' PAUL STRAUBE,
Watchmaker, Kiomell House, Conway Road, Colwyn Bay, do hereby declare
the nature of this invention to be as follows:-
The object aimed at in the design of the above "spring bolt" is to obtain the
instant release of a connection made with the same, by the application of a tensional
foree (if necessary from a distance by means of a cord or chain) which acting on a
steel spring causes it to contract, thereby allowing a bolt to leave its socket and
release the connection.
The invention consists of a shaft "A" with forked end "a. a." through which is
inserted the bolt "FK D." On the projecting limb "D" is a steel spring "C"
which by exerting a pressure against the lower fork "a" and simultaneously against
the ring at "D" retains the bolt "K F."in its socket, through the two forks." a. a."
thereby securing the ring at "E." (see Fig. 1. shewing bolt closed).
The shaft "A" being a fixture, by pulling the chain "B" in the direction of the
arrow (Fig. 2.) causes the spring ""to contract, thereby allowing the short limb
of the bolt "K" to leave its socket "F.".thereby releasing the ring. "E" to which
any desired connection is made.
Fig. 3. shows top view of bolt closed.
The bolt "FK D." also shaft "A" and "a. a." is made of either wrought or "cast
iron. The rings at "E. K. and D." to be of wrought iron. The bolt to. bent at "K"
as shewn on drawing and to allow of it sliding easily through the circular sockets or
holes at "F. & K. The ring "E." to fit easily between the forks "a. a." The
spring "C" to be of the best tempered steel wire, yielding to a tension of about 3 lbs.
The chains and other accessories are not included in the invention for which
application for patent is now made, being shown merely to illustrate the working of
the invention.

COMPLETE SPECIFICATION.
An Improved Spring Bolt or Fastening for Chains and the like.
VICTOR ALBERT, Jeweller, Conway Road, Colwyn Bay and PAUL STRAUBE,
Watchmaker, Kinmell House, Conway Road, Colwyn Bay, 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 object aimed at in the design of the above "spring bolt" is to obtain the

page_text: instant release of a connection made with the same by the application of a tensional
force (if necessary from a distance by means of a chain or cord) which acting on a
steel spring causes it to contract thereby allowing a bolt to leave its socket and release
the connection. It is applicable to any purpose in which the instant release of a
connection is an advantage, but more especially to a cattle or other stable in which
there is a succession of stalls for the accommodation of beasts including cattle and
horses in order to obtain the instant release of their halters or fastenings as in case of
fire or other emergency as hereinafter described.
We will describe our invention by referring to the drawings left with our
Provisional Specification.
Fig. 1. shews an elevation of the said spring bolt closed thereby securing the said
chain or fastening.
Fig. 2. shows an elevation of the said spring bolt open, releasing the said chain or
fastening.
Fig. 3. shews the plan or top view of the said spring bolt, closed, securing the said
chain or fastening.
The same letters of reference indicate the same parts in all the figures.
Our invention consists of the shaft "A" with forked end "a a" through which is
inserted the bolt "F. K. D." On the projecting limb "D" is a steel spring "C"
which by exerting a pressure against lower fork "a" and simultaneously against
the ring at "D" retains the bolt "F" in its socket through the two forks "a a'
thereby securing the ring at "E" attached to the halter or other fastening of the
beast or horse (see Fig. 1).
The shaft "A" is a fixture (preferably built into wall and bolted on other side);
by pulling the chain "B" in the direction of the arrow the spring "C" is caused to
contract and the short limb of the bolt "K" is allowed to leave its socket thereby
releasing the ring "E" to which is made the desired connection as aforesaid.
The bolt "FK D" also shaft "A a" to be made of either wrought or cast iron
the rings at "EK & D" to be made of wrought iron the bolt to be bent at "K" in
the form of a semicircle as shewn on drawing to allow of it sliding easily through the
circular sockets or holes at "F & K." The ring "E" to fit easily between the
fork "a a." The spring "C" to be of the best tempered steel wire, and to yield to
a tension of 3 pounds.
When our invention is applied to a stable or the like the method of working is as
follows:-
The chain or communication cord "B," which is attached to the part "K" of the
bolt as shewn, is attached to a lever or handle at one end of the stable or building; a
cord or chain is also attached to the part "D" of the bolt as shewn and this chain is
continued through to the next stall & is attached to the part "K" of the bolt there
and the limb "D" of the same is connected to the part "K" of the next bolt in
succession and so on.
Pulling the said handle or lever at the end of the stable or building as aforesaid in
the direction of the arrow, causes each bolt in succession to be drawn, thereby
releasing simultaneously the fastenings or connections from the beasts or horses to the
ring "E" as shewn on Figure 2.
It will be evident from the foregoing that our invention can be similarly applied to
many purposes other than that specified herein.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The berein described improved spring bolt or fastening for chains and the like, permit-
ting of the instantaneous release of a connection or fastening made to the halters of beasts
or horses, either singly or in a succession of stalls, or for any other purpose to which
the said invention may be applied, by means of a tensional force, if convenient acting
from a distance, upon a bolt thereby contracting a spring on a limb of the same, so
causing the holt to be withdrawn from its socket in the forked end of a shaft which is

page_text: a fixture and to release thereby a ring the bolt secured, to which is made a connection
or fastening to the halter or collar of a beast or horse, and the like or other connection
for the purpose of release, in cases of emergency or otherwise as hereinbefore described
and illustrated by the drawing left with our Provisional Specification.
