Improvements in Carts and Wagons.
We, EDWARD CHRISTOPHER BLACKSTONE, of Rutland Engineering Works,
Stamford, in the County of Lincoln, Agricultural Implement Manufacturer, and
JOHN WILLIAM GOODWIN, of Great Casterton, in the County of Rutland, Wheelwright,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in carts and wagons, the improvements
consisting in improved means for regulating the inclination or tip to be given to the
body of the cart or wagon when unloading, in a self-acting arrangement for raising
the body of the cart after discharging the load, and in improved means for securing
the tailboard and front and back boards to the body of the cart or wagon.
According to our invention we joint the shafts to the body of the cart or wagon,
and in front of the said hinged joint we provide each shaft with a curved bar. or
bracket which is preferably U-shaped. The front of this bracket is curved so as to
form a segment of a circle and is provided on its outer edge with notches placed
at suitable distances apart.
We also provide a locking bar which is supported in guides on the two shafts in
such a position that it will engage with the notched arms so as to hold the body of
the cart either level or in any position required. Near each end of the said bar a
notch is formed and we also provide means, such as a hand lever pivoted to one of
the shafts and to the bar, whereby the said bar can be pulled so that it slides in its
guides and brings the notches at each end opposite the notched arms of the curved
plates, whereby the said arms are free to move upwards and allow the body of the cart
or wagon to be tipped.
Means are also provided for retaining the locking bar in its outer position, such
means consisting, for instance, of a catch designed to engage with a notch in the said
bar and a spring is advantageously arranged to pull the bar backwards into its normal
position when the catch is released from the notch in the same.
For limiting the extent to which the body of the cart or wagon can be tipped, we
advantageously employ a stop against which the bottom or loop of one of the curved
notched bars strikes. This stop advantageously consists of a spring-pin which passes
through one of the shafts and is provided at its outer end with a handle and with a
small transverse pin which enters a recess in the shaft. The said spring-pin can be
pulled outwards by means of the handle and turned so that the small pin drops into a
hollow groove in the shaft when the stop pin has reached the level of the inner surface
of the shaft.
By this means the stop-pin is rendered inoperative when desired.
By curving the frame downwards the body of the cart may be arranged to slip
backwards slightly when tipping. After it has discharged its load the horse is backed
and the body of the cart thus thrust forward until it falls into a horizontal position.
The tailboard of our improved cart or wagon is hinged at its lower end to the sides
and is designed to be secured to the sides by means of latches hinged to the said tail-
board and designed to engage with catches secured to the said sides. A lever is proivded
whereby the latches can be lifted from the catches so as to free the tailboard, the said
lever being secured in position by a link or other means when the tailboard is in position.

catches on the said sides.

Improvements in Carts and Wagons.
We, EDWARD CHRISTOPHER BLACKSTONE, of Rutland Engineering Works,
Stamford, in the County of Lincoln, Agricultural Implement Manufacturer, and
JOHN WILLIAM GOODWIN, of Great ('asterton, in the County of Rutland, 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:-
:
This invention relates to improvements in carts and wagons the improvements
consisting in improved means for regulating the inclination or tip to be given to the
body of the cart or wagon when unloading, and in improved means for securing the
tailboard and front and back extension boards to the body of the cart or wagon.
In the accompanying drawings,
Figure 1 is a side elevation of a portion of a cart having applied to it our improved
means for regulating the tip; and,
Figure 2 is an underside view of the same:
.
Figure 3 is an underside view.,illustrating a modification of this part of our
invention:
Figure 4 is an elevation of the rear portion of a cart body provided with our
improved means for securing the tailboard and the extension boards.
Similar letters of reference indicate corresponding parts in the several figures.
According to our invention the shafts a Figures 1 and 2 are jointed to the body b in
the usual, manner, for instance, by means of hinges as at c. To the body b we fix two
brackets d, one in connection with each shaft, which brackets are each provided with
a series of notches e, e, and have their notched edges curved to the arc of a circle
having its centre at the joint c between the body and the shafts. Transversely of the
shafts beneath the cross-brace f, we arrange a locking bar g adapted to slide in-
brackets h, h fixed on the underside of the shafts, the said locking-bar g having in it
two notches i, i which will coincide with. the two brackets d, d as shewn in Figure 2,
and being designed to fit with its edge into the notches e, e.
With this arrangement, it will be understood that when the locking bar g is in the
position in which un-notched portions of its edge engage in the notches e, e the body
will be prevented from tipping relatively with the shafts, whilst when the said locking-
bar is moved so that the notches i, i therein are opposite to the brackets d, d the body
can be tipped. j is a spring for normally holding the bar in the position to lock the
body, the said spring, as shewn in the drawing, being arranged in a recess in the
cross-brace the said spring bearing with one end against one end of the recess whilst
the other end of the spring bears against a projection k on the locking bar g.
To one end of the locking bar g we.connect one end of a lever pivoted at m in a
bracket on one of the shafts a, the other end of, the said lever being formed as a
handle by means of which the locking bar g may be moved. In order that when the
locking bar g has been moved to allow the tipping of the body, it may be retained in
its position until the body is to be again locked, we provide a retaining catch o pivoted
to one of the shafts a at o¹ and having a handle o2 for operating it, the said catch when
the bar is moved, as before indicated, being designed to engage in a notch p
7.

page_text: (Figure 2) in the said bar. The catch itself is notched, as shewn at p³, Figure 1, so
that when it is turned down to lock the bar g it will rest with the top of the notch
upon the top of the said bar.
In order to limit the tipping of the body so that the brackets d, d shall not move
beyond the locking bar g, we provide in one of the shafts a a pin g which projects
into the inside of the bracket and serves as an abutment against which the bottom of
the bracket will strike. To provide, however, for tipping the body to a greater extent
when desired, we arrange that the said pin can be withdrawn to the required extent.
For this purpose the said pin 9 has on the outside of the shaft a a handle q'; a spring r
arranged in connection with the said pin q serves normally to hold it in its projecting
position and a cross-pin which normally lies in a slot Figures 1 and 2 serves
when the pin g is drawn outwards against the pressure of the spring r to prevent the
return of the said spring q, the cross pin in this case lying in a shallow notch 7.*
arranged transversely of the slot ².
The modification of our invention, shewn in Figure 3, only differs from that
hereinbefore described in that the catch o is arranged as a spring catch and is operated
by a finger lever s on the lever l.
The tailboard t of our cart or wagon as shewn in Figure 4 is hinged at u and is
designed to be secured at the two sides by latches v engaging with catches won the
sides of the cart, these latches are secured to the two ends of a shaft having fixed
to it an arm or lever a¹ by means of which the shaft a may be turned to engage and
disengage the latches with and from the catches w. A link or ring 2 carried on the
tailboard is designed to engage with the end of the lever to hold the latter and
prevent it from turning inadvertently. y, y are the extension boards at the sides,
(front) and back of the cart which boards are held together at the corners by latches
and catches, as shewn at z Figure 4.
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 :-
1. The improved means for regulating the inclining or tipping of cart bodies,
substantially as hereinbefore described and illustrated in Figures 1 to 3 of the
accompanying drawings.
2. The improved means for securing the tailboard and front, back and side extension
boards of carts, wagons, and the like, substantially as hereinbefore described and
illustrated in Figure 4 of the accompanying drawings.
