PROVISIONAL SPECIFICATION.
A New or Improved Draw Bolt for Carriages and other Vehicles.
I, WILLIAM GALLON, of 2, Fern Cottages, Wick Road, Hampton Wick,
Middlesex, Coach Smith, do hereby declare the nature of this invention to be
as follows:-
My invention relates to a new or improved draw bolt for carriages and other
vehicles the object being to substitute for the hook or the like now employed
for attaching the trace to the splinter bar, a spring bolt so as to allow of the trace
being quickly and easily released in case of accident, thus rendering it unnecessary
to cut the trace in the event of the horse falling down, while this improved bolt
may be connected to the spring which is now frequently provided on the bar
attached to carriages and the like to ease the "pull" and lessen the sudden strain
upon the shoulders of the horse, but in cases where such a spring is not provided
my improved bolt is attached to the end of a short rod furnished with a powerful
spring, contained within a cylindrical barrel or chamber.
In carrying my invention into practical effect my improved spring bolt consists
of a suitable U shaped frame between the arms of which the end of the trace is
placed while a spring bolt of sufficient size passes through the ends of the arms of
the said frame also passing through the slot formed in the end of the trace, so that
in the event of accident, and it becomes necessary to quickly release same it is only
necessary to raise the said spring bolt and the trace can be at once withdrawn from
between the arms of the U shaped frame. This bolt consists of the locking or
bolting pin passing through the ends of the U shaped frame, a cross or connecting
piece running parallel to one of the sides of same and a second rod passing through
the lower part of the U shaped frame and furnished with a sufficiently powerful

splinter bar is provided with the well known "draw" springs my improved spring
draw bolts are furnished with rearwardly extending arms or connecting rods
passing through holes in the said splinter bar and connected to the free ends of
the draw springs in any suitable manner, while in the event of the carriage or
other vehicle not being provided with the latter the aforesaid rearwardly extending
arm is fitted with a powerful spring contained within a suitable cylindrical chamber
or receptacle, the said cylindrical chamber being furnished with suitable lugs or
connecting pieces by means of which it may be bolted to the splinter bar, and in
this case the spring bolt is arranged at right angles to the arms of the U shaped
frame, instead of being parallel to them as in the former instance.
As my improvements are capable of some modifications without departing from
the principle thereof, 1 do not restrict myself to materials, dimensions or to the
precise form or placement of the several parts thereof.

A New or Improved Draw Bolt for Carriages and other Vehicles.
I, WILLIAM GALLON, of 2, Fern Cottages, Wick Road, Hampton Wick,
Middlesex, Coach Smith, 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:-
My invention relates to a new or improved draw bolt for carriages and other
vehicles the object being to substitute for the hook or the like now employed for
attaching the trace to the bar, a spring bolt so as to allow of the trace being
quickly and easily released in case of accident, thus rendering it unnecessary to
cut the trace in the event of the horse falling down, while this improved bolt may
be connected to the spring which is now frequently provided on the bar attached
to carriages and the like to ease the "pull" and lessen the sudden strain upon
the
shoulders of the horse, but in cases where such a spring is not provided my
improved bolt is attached to the end of a short rod furnished with a powerful
spring, contained within a cylindrical barrel or chamber.
In carrying my invention into practical effect my improved spring bolt consists
of a suitable U shaped frame between the arms of which the end of the trace is
placed while a spring bolt of sufficient size passes through the ends of the
arms of the said frame, also passing through the slot formed in the end of
the trace, so that in the event of accident, and it becomes necessary to
quickly release same it is only necessary to raise the said spring bolt and the trace
can be at once withdrawn from between the arms of the U shaped frame. This
bolt consists of the locking or bolting pin passing through the ends of the
Ushaped frame, a cross or connecting piece running parallel to one of the sides
of same and a second rod passing through the lower part of the U shaped frame
and furnished with a sufficiently powerful spring contained within a suitable
cylindrical barrel or chamber. Where the bar is provided with the well known
"draw" springs my improved spring draw bolts are furnished with rearwardly
extending arms or connecting rods passing through the holes in the said bar and
connected to the free ends of the draw springs in any suitable manner, while in the
event of the carriage or other vehicle not being provided with the latter the
aforesaid rearwardly extending arm is fitted with a powerful spring contained
within a suitable cylindrical chamber or receptacle, the said cylindrical chamber
being furnished with suitable lugs or connecting pieces by means of which it may
be bolted to the bar.
In order that my invention may be more fully understood, I will now proceed to
describe same with reference to the accompanying drawings in which
Fig. 1 is a plan of my improved draw-bolt showing one form or arrangement of
same,
Fig. 2 being a side elevation of Fig. 1 and
Fig. 3 a sectional elevation of the end portion of a bolt illustrating the form of
construction.
Fig. 4 is a plan and Fig. 5 a side view of a modified form of bolt particularly
intended for use in connection with hansom cabs.
Fig. 6 is a plan of one of my improved bolts in connection with a specially
arranged draw spring,
Fig. 7 shows a bolt used in connection with swing-bars.
Figs. 8 and 9 show in plan and front view an improved pole crab fitted with my
improved spring bolts.
Referring now more particularly to Figs. 1, 2 and 3 my improved bolt consists
essentially of a U-shaped frame a, a cross piece a' carrying locking pin p at one
end, which passes through the arms of the U-shaped frame, the other end being

page_text: furnished with a rod (Fig. 3) contained within the cylindrical barrel or
chamber c, a spiral springs being arranged around the said rod and confined
between the closed end of the chamber cand a plug pl screwed onto the rod r.
The end of the trace is placed between the arms of the U-shaped frame a, the
pin p passing through a slot formed therein so as to prevent the removal of the
trace until the pin p has been drawn back, which is readily effected by gripping
the cross piece a¹ and applying the necessary pressure, the bolt immediately resuming
its normal or closed position as soon as the cross piece a is released, by reason of
the spring s.
This improved bolt is provided with a rearwardly projecting arm or rod b designed
to pass through a hole in the draw bar where the free end may be-secured in any
suitable manner to a draw spring of well known construction for the purpose of
relieving the strain on the shoulders of the horse, or if required the said bar may
be cylindrical in form and screw threaded so as to screw into the draw bar when
it would be furnished with a locking nut at the back.
The bolt shown in Figs. 4 and 5 which is particularly intended for use in
connection with hansom cabs, is precisely the same in construction as the bolt
above described. In this case the rearwardly projecting rod b is dispensed with
and the bolt furnished with a blank lug as shown. This lug is designed to be
bored or furnished with a hole or perforation in the required position so as to be
bolted to the bracket to which the traces are at present usually secured.
The bolt shown in Fig. 6 is of similar construction to those hereinbefore
described, but in this case the rearwardly extending arm or rod b passes into the
cylindrical body or chamber d where it is fitted or furnished with a sufficiently
powerful draw spring s for relieving the strain upon the shoulders of the horse,
and which is shown in dotted lines in the drawings. The body or chamber dis
furnished with two projecting lugs l, furnished with slots g, g¹ by means of
which it may be securely bolted to the draw bar.
The bolt shown at Fig. 7 is intended for use in connection with swing-bars
and while the bolt itself is of similar construction to those herein before referred to
it is mounted upon or formed integrally with a socket into which one end of the
swing-bar enters and is securely fastened, the other end of the said bar being
likewise furnished with a corresponding bolt.
The improved pole crab illustrated in Figs. 8 and 9 consists essentially of a
socket designed to be permanently secured to the end of the pole and which is
furnished with two spring bolts, one on either side, of a similar construction to those
hereinbefore described. In this case the ends of the traces are permanently
secured to the metal connections each of which is furnished with a projecting
arm having an enlarged perforated end k² through which the locking pin p of
the bolt passes, so that upon drawing back the bolt the metal connection can be
drawn out thus releasing the traces. For additional security the two bolts may be
connected together by a cross or bridge piece m as shown in Fig. 9.
I wish it to be understood that I do not restrict myself to the exact form or
arrangement of bolt herein described, as it may be slightly modified to suit various
requirements without departing from the principle and spirit of the invention, while
it may further be made in various sizes and used in connection with haruess when
and where it can be advantageously employed.
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 [
claim is :-
1. The new or improved draw bolt consisting essentially of U-shaped frame a,
locking pin p, cross piece a', rod r, cylindrical chamber c, spring s and plug p¹, in
combination with a rearwardly extending arm such as 6 or other suitable means
for fixing, substantially as herein described and shown in the accompanying
drawings.
2. The modified forms or arrangements, of the bolt above claimed, substantially

page_text: as herein described and shown with reference to Figs. 4 to 9 of the accompanying
drawings, and for the purposes specified.
3. The new or improved bolt for carriages and other vehicles substantially as
.herein described and shown and for the purposes specified.
Dated this 1st day of May 1896.
