PROVISIONAL SPECIFICATION.
Improvements in the Drawing-gear of Carts and other Road
Vehicles.
I, RICHARD STOREY, of Ings, near Kendal, in the County of Westmoreland, Joiner
and Wheelwright, do hereby declare the nature of this invention to be as follows:-
In the ordinary arrangement of the drawing gear of carts and other road vehicles
the gear is fastened directly to the shaft the "drawing staple" having its two ends or
legs passed downwardly through vertical holes in the body of the shaft and being
rigidly secured thereto by means of screw nuts. Hence the shafts have to sustain the
entire draw or pull required to move the vehicle.
According to my invention 1 so arrange the drawing gear in conjunction with a
chain in such manner that the draw or pull is removed from the shaft and transferred
to the wheel axle. To this end 1 make a vertical elongated slot through the body of
the shaft and insert loosely therein the upper part of a malleable metal casting whose
lower part constitutes a bottom plate having its rear end in the form of a loop which
receives one end of a chain whose other end is secured to the wheel axle. The metal
casting has two holes (front and rear) through which are passed the two ends of legs
of the drawing staple the latter being secured to the casting by screw nuts in the
usual way. The upper part of the casting (or that part which occupies a position within
the body of the shaft) consists of a vertical plate or wing enlarged at its two
extremities the enlarged parts containing the holes through which the legs of the
staple are passed. The vertical plate and its enlargements pass up through the shaft
and the lower faces of collars on the staple and the upper face of the bottom plate are
free to slide lengthwise upon slotted metal protecting plates secured to the upper and
lower sides of the shaft. The improved drawing gear is thus mounted so as to be
movable upon or as regards the shaft and the connecting chain is of such a length
that the pull on the drawing gear is transmitted to the wheel axle the pull being
thereby removed from the shaft as hereinbefore stated.

Improvements in the Drawing-gear of Carts and other Road
Vehicles.
I, RICHARD STOREY, of lngs, near Kendal, in the County of Westmoreland, Joiner
and Wheelwright, 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 :-
"
In the ordinary arrangement of the drawing gear of carts and other road vehicles
the gear is fastened directly to the shaft the drawing staple" having its two ends or
legs passed downwardly through vertical holes in the body of the shaft, and being
rigidly secured thereto by means of screw nuts. Hence the shafts have to sustain the
entire draw or pull required to move the vehicle.
According to my invention I so arrange the drawing gear in conjunction with a
chain in such manner that the draw or pull is removed from the shaft and transferred
to the wheel axle. To this end I make a vertical elongated slot through the body of
the shaft and insert loosely therein the upper part of a malleable meial casting whose

page_text: lower part constitutes a bottom plate having its rear end in the form of a loop which
receives one end of a chain whose other end is secured to the wheel axle. The metal
casting has two holes (front and rear) through which are passed the two ends or legs
of the drawing staple the latter being secured to the casting by screw nuts in the
nsual way.
The upper part of the casting (or that part which occupies a position
within the body of the shaft) consists of a vertical plate or wing enlarged at its two
extremities the enlarged parts containing the holes through which the legs of the
staple are passed. The vertical plate and its enlargements pass up through the shaft
and the lower faces of collars on the staple and the upper face of the bottom plate are
free to slide lengthwise upon slotted metal protecting plates secured to the upper and
lower sides of the shaft. The improved drawing gear is thus mounted so as to be
movable upon or as regards the shaft and the connecting chain is of such a length
that the pull on the drawing gear is transmitted to the wheel axle the pull being
thereby removed from the shaft as hereinbefore stated.
In the accompanying drawings
Figs. 1 and 2 shew a cart of ordinary construction having my improved drawing
gear as hereinabove described applied thereto.
Fig. 3 is a sectional view (drawn to a larger scale) of that part of the apparatus
which occupies the slot or elongated opening in the cart shaft.
In Fig. 1 the drawing gear apparatus is shown in the position which obtains when
the horse is drawing or pulling the cart; and in Fig. 2 when the horse is backing or
taking the cart down hill.
a is the cart shaft; ban elongated vertical slot therein; a metal casting or
sliding block capable of moving lengthwise of the shaft in the slot or opening b, the
said sliding block having an enlarged part forming a bottom plate or flange d
provided at its rear end with a joint e to which is connected one end of a sliding rod
or draw bar whose other end is connected to a chain g fastened to the axletree h.
The casting has two vertical holes through which are passed the two legs ii of the
drawing staple, the said staple having fast collars jj above and being fastened below
by means of screw nuts as shewn. On the upper and lower sides of the shaft a are
two slotted metal plates forming bearings or wearing surfaces for the sliding
block c and attendant parts.
When the horse is drawing a loaded cart up hill the casting e and draw bar fare
drawn forward (see Fig. 1) thus tightening the chain g and transferring the pull on
to the axle h and the tendency to draw down the part 2 to a straight line between the
points e and produces a downward pull at the part thus placing more weight or
pressure on the horse's back. When the horse is going down hill or ceases pulling
the chain g becomes slack and the horse is relieved of the weight.
Fig. 4 illustrates an arrangement of break apparatus which may be used in con-
junction with the improved drawing gear hereinabove described. The rear end of the
draw bar fis jointed to one end of a lever 7 centrally fulcrummed on a fixed stud at m.
A rod s connects the other end of the lever with one arm of a bell crank lever n
working on a centre p (which may consist of a cross shaft mounted in bearings or
brackets fastened to the axletree). At each of its two ends the lever n is connected
to the free ends of sheet metal break bands or straps whose other ends are made
fast to fixed studs or pins it on the side of the cart. By the arrangement just
described when the horse is taking a loaded cart down hill the draw bar will be
pushed rearwards (as shown in Figs. 2 and 4) thereby causing through its action on
the levers and n the break bands or straps to be drawn tight round the periphery
of the wheel nave o. On the other hand when the draw bar f is pulled forward the
break pressure will be withdrawn by the opening out of the break bands clear of
the nave.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In carts or other road vehicles the employment of drawing gear capable of moving

page_text: or sliding lengthwise of the shaft the said drawing gear being connected to the axle
of the cart or other vehicle and operating substantially as hereinabove described and
shown in the drawings.
