PROVISIONAL SPECIFICATION.
An Improvement in Fastening Traces to Vehicles.
PATRICK PARKER 32 Gospel Oak Grove Kentish Town Carpenter and Joiner,
do hereby declare the nature of this invention to be as follows:-
The said spring slip trace is attached to the shaft of any vehicle by the action of
which the traces cannot be released unless by touching the spring or lever. The
object of the invention is to assist draught animals to rise on falling & to prevent
them injuring themselves by immediately releasing the traces.
The trace holder is made of five sixteenths of an inch (1) wrought iron
throughout.
The cylinder is 4 inches, (four and one half) long; one and five eighths
inches (1) in diameter; the bore one inch (1) and the steel spiral spring seven
eighths and one sixteenth in diameters respectively (& in.).
in.).
The base is three & one half inches long (3½ in.); one inch & five eighths
wide (1 in.); and one inch and one sixteenth deep (1
The slide, to which the traces are fastened, is three and half inches long (3 in.);
one inch wide (1 in.), and one half inch thick (in.).
The mortice in the centre of the slide is one inch long (1 in.), and one quarter inch
wide (in.).
The traces are to be attached, by a ring or hook, to the slide, which fits and
runs along the base. The slide has a mortice in the centre, through which the
bolt, attached to the spring inside of the cylinder, passes, and secures or releases
the traces on raising the spring placed in the cylinder.
The trace holder may be attached to the draught bar of any vehicle; or to the
head pole of an omnibus, carriage or wagon.
COMPLETE SPECIFICATION.
An Improvement in Fastening Traces to Vehicles.
I, PATRICK PARKER, of 32 Gospel Oak Grove, Kentish Town, Carpenter and
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:—
The said spring slip trace holder is attached to splint bar on pole of any vehicle,
and allows of the traces and pole chains being released by the medium of a lever
to which the said spring slip trace holder is connected in both cases.
Figs. 1 and 2 are respectively longitudinal and transverse sections shewing the
method of attachment for the traces to the splint bar; Fig. 3 is a longitudinal
section, Fig. 4 is a sectional plan and Fig. 5 is a transverse section shewing the
attachment of the pole chains to the pole, whilst Fig. 6 is a front and Fig. 7 a side
view shewing the connection of all the slips to one common releasing lever.
In Figs. 1 and 2 a is the splint bar to which the cylinder 6 is attached. Within
the cylinder is a bolt c urged against the jaws d of the splint bar by a spring g.
The end of the bolt e passes through a hole in each of the jaws d thus keeping in
its place between the two jaws the ring e to which the trace is attached.
C
The other end of the bolt c is screwed into an eye nut, to which is attached a
chain, wire, strap, or other pull which passing over guide pulleys as shewn in
Figs. 6 and 7 connects to the lever . The lever is placed in some convenient

page_text: position near the hand or foot of the driver, who by moving this lever as is shewn
in Figs. 6 and 7 can withdraw the bolt c thus releasing the trace rings e.
The same description is applicable to the trace holder as applied to the pole
chains as shewn in Figs. 3, 4 and 5 e¹ el being the pole chain rings.
The eye nut is flexibly connected to the lever as shewn in Fig. 7. The
motion of the lever which releases the traces as above described communicated
by cords or chains passing over guide pullies p releases also the pole chains
simultaneously.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A fastening for traces to vehicles, substantially as herein described and illustrated
by the accompanying drawings.
Dated this 29th day of May 1892
