TRUVIDIUNAL DE BUITIVATION.
An Attachment for Cart Saddles.
I, ROWLAND HENRY NORMAN, of Eldersfield Court, Tewkesbury, in the
County of Worcester, Farmer, do hereby declare the nature of this invention to
be as follows: :-
This invention relates to a device to be attached to the channel of an ordinary
cart saddle for the purpose of preventing the chain or the like from accidentally
leaving the channel in the cart saddle.
The cart saddle attachment which forms the subject of this invention consists
of a suitable base on which is formed a screw, or provided with screw holes, by
means of which it is screwed to the cart saddle. This base carries a bifurcated
upright or two uprights, between the cheeks of which a rod or bar is pivotted.
This rod or bar is weighted at one end and is so constructed and affixed to
the upright or uprights that it is normally horizontal and can only turn through
an angle of 90 degrees i.e. the weighted end can only turn from its normal
horizontal position upwards to a vertical position. The device is attached to the
cart saddle in such position that the unweighted end of the pivotted rod or bar
nearly bridges over the channel in the cart saddle.
When the chain or the like is placed in the channel the unweighted end of
the pivotted rod or bar turns down from its normal horizontal position to a
vertical position or nearly so, thus allowing the chain to pass down into the
bottom of the channel. When this is effected the weight of the chain is off the
rod or bar, which then returns to a horizontal position. Should the chain rise
in the channel it will press against the underside of the unweighted end of the
rod or bar, but as this cannot move upwards beyond the horizontal position it
will effectually prevent the chain or the like from accidentally rising out of the
channel. To remove the chain it is only necessary to unhook the end of chain
in the ordinary way when it will slide out under horizontal bars. To remove
other appliances, press down unweighted ends of pivotted rods or bars. One or
more of these devices as desired may be secured to the cart saddle in suitable
positions thereon.

COMPLETE SPECIFICATION.
An Attachment for Cart Saddles.
I ROWLAND HENRY NORMAN, of Eldersfield Court, Tewkesbury, in the
County of Worcester, Farmer, 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 a device to be attached to an ordinary cart saddle for
the purpose of preventing the back chain or the like from accidentally leaving the
channel or groove in the cart saddle.
In the accompanying drawings
Figure 1 shews a section of a cart saddle with two of my devices attached thereto
opposite another, and

page_text: Figure 2 shews the position into which they should be turned when it is desired
to place the chain in or to lift it vertically from the channel or groove A in the
cart saddle;
Figure 3 is a plan of Figure 1; and
Figures 4, 5 & 6 shew detached views of the parts.
In all the figures the same letters of reference are used to indicate the same or
corresponding parts.
:
The cart saddle attachment which forms the subject of this invention consists of
a suitable base B on which is formed a screw, or it is provided with screw holes C,
by means of which, it is screwed, or it may be otherwise attached to the ridges D
between which is the channel or groove A of the cart saddle. This base B carries
a bifurcated upright E or two uprights between the cheeks of which a rod or bar F
is pivotted at H. This rod or bar F is weighted at one end G or is pivotted so
that it is heavier at the rear than at the front, and is so constructed and affixed to
the upright or uprights E that it is normally horizontal and can only turn forwards
through a vertical angle of at most 90 degrees, ie. -the weighted end G can only
turn from its normal horizontal position upwards to or towards a vertical position
as shewn in Figure 2. This is conveniently effected by the method of construction
shewn more particularly in Figures 4, 5 & 6. Figure 4 is a detached elevation of
the rod F; Figure 5 is a plan of the bifurcated upright E, and Figure 6 is n
vertical section on the line X Y Figure 5. A bulge or projection J is formed on
the underside of the rod F and in the rear side of the pivot, that is, the side nearest
the weighted end G. The channel K between the cheeks of the bifurcated
upright E is inclined downwards from the rear towards the front, that is to say,
away from the weighted end G of the rod F. This inclined channel is shewn in
full lines in Figure 6 and in dotted lines in Figures 1 and 2. The upper and rear
end of this channel K therefore forms a stop on which the bulge or projection .J
rests, thus keeping the rod normally horizontal. It is obvious that the upper end
of the channel K may be made somewhat higher so as to dispense with the bulge or
projection J on the rod F. Or the incline K may be dispensed with and a stop
cast or otherwise formed or attached to the rear of the bifurcated upright or to the
rear of both uprights when two are used, on to which the rear or weighted end of
the pivotted rod F will abut and prevent the rod from falling lower than the
position shewn in Figure 1. Or other means to effect the same result may be
dopted if so desired, without departing from the nature of my invention.
When only one of these devices is used, it is attached to the cart saddle in such
position that the unweighted end of the pivotted rod or bar F nearly bridges over
the channel in the cart saddle. When two are used arranged in a pair opposite to
one another as illustrated in Figures 1, 2 & 3 they may be of sufficient length to
meet or nearly meet at their front ends so as to bridge or nearly bridge the groove
or channel A. It will be understood that more than one of these devices bridging
the channel A, may be used and they may be disposed in suitable positions, as also
when the devices are arranged in pairs, as shewn in Figures 1, 2 & 3, more than
one pair may be used if required.
When inserting the chain or the like L in the channel A as shewn in Figure 2,
the unweighted end of the pivotted rod or bar F turns down from its normal
horizontal position to a vertical position or nearly so, thus allowing the chain to
pass down into the bottom of the groove or channel A. When this is effected the
weight of the chain or the like L is off the rod or bar F which then returns to a
horizontal position as shewn in Figure 1. Should the chain rise in the channel it
will press against the underside of the unweighted end of the rod or bar F but as
this cannot move upwards beyond the horizontal position it will effectually prevent
the chain or the like from accidentally rising out of the channel.
To remove the chain it is only necessary to unhook the end of chain in the
ordinary way when it will slide out under horizontal bars. To remove other
appliances, press down unweighted ends of pivotted rods or bars into the position
shewn in Figure 2.

page_text: 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 :-
An attachment for cart saddles consisting of an upright or uprights carrying
a rod or bar pivotted so as to rest normally horizontal, and capable of being
turned inwards towards the chain when required, but prevented by a stop or its
mechanical equivalent from turning outwards away from the chain substantially
as and for the purpose herein before described.
