PROVISIONAL SPECIFICATION.
An Improved Shifter and Fastener for Movable Seats and Tailboards
of Carts and such like.
I, WILLIAM FEATHERBY, Roughdown, Beechcroft Road, New Bushey, Herts.,
Coachbuilder, do hereby declare the nature of this invention to be as follows:-
By means of a fixed spring and double lever two bolts are simultaneously shot
into or withdrawn from fitting holes in the sides of the cart or carriage. These
bolts lie in a groove in the seat or tailboard of the cart & the lever is worked by.
pressing a thumbpiece, knob or such like placed conveniently on the outside edge.
The lever has its fulcrum at or near its centre and two joints or cranks respec-
tively join the two bolts to it. One joint or crank is worked by the end of the lever
remote from the fulcrum & the other is worked by the same action from a position
between the fulcrum and the thumbpiece or exposed knob on the end of the lever
so that when the knob is pressed both bolts are withdrawn from the side of the
cart into the groove. The spring is so fixed as to press outwardly on the lever &
joint & so to shoot the two bolts at the same time when the pressure is removed
from the knob.

An Improved Shifter and Fastener for Movable Seats and Tailboards
of Carts and such like.
I, WILLIAM FEATHERBY, of Roughdown, Beechcroft Road, New Bushey, Carriage
Builder, 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 an improved device or means for fastening seats, and tail-
boards of carts and such like, the object being to provide a device of extremely
simple construction which shall firmly hold the seat or tailboard in the required
position, while it is capable of being quickly released so as to allow of the seat or
tailboard being easily removed as desired, moreover the whole of the mechanismu
being contained within the seat, there are no projecting parts, with the exception
of the end of the operating lever, and thus the liability of articles, such as port-
manteaux and the like, becoming scratched or damaged when placed under the
seat, is obviated, while the locking arrangement is not so liable to become deranged.
In order that my invention may be fully understood I will now proceed to

page_text: describe same with reference to the accompanying drawings in which Fig. 1 is
a plan of a seat showing the application of my improved locking or fastening
means thereto.
.
Fig. 2 is a front view of same with the covering plate removed.
Fig. 3 is a plan of the locking device detached and drawn to an enlarged' scale.
with the top plate removed.
In carrying my invention into practical effect my improved device comprises a
double lever a pivoted at a¹ and furnished with an operating knob a², while to the
free end of the lever a one of the bolts bis pivoted at 2, the second bolt 6¹ being
pivoted between the fulcrum of the lever a and the operating knob a², as at 2,
two fixed springs s s¹ being arranged as shown for keeping the bolts b, 61, in the
forward positions, in such a manner as to allow of their ends engaging with holes
or the like formed in the side of the cart or vehicle.
The bolts and their operating mechanism are arranged within grooves or
recesses formed in the seat S as shown in Figs. 1 and 2, in such a manner that
only the ends of the bolts 6, 61, and a small part of the operating lever a project.
When it is required to release the seat, tailboard, or the like, it is only necessary
to press the knob a² of the operating lever a from right to left, when the two
bolts 6 b', are simultaneously withdrawn into the grooved or recessed portions of
the seat, and in such a manner as to be clear of the holes or recesses in the sides of
the cart or the like, while upon releasing the operating lever a the bolts 6, 61, are
simultaneously and automatically shot forward under the action of the fixed
springs s, s¹.
The operating mechanism is preferably arranged between two plates, the lower
one g of which is shown at Fig. 3.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. The improved means for securing or fastening moveable seats and tailboards of
carts and such like, substantially as herein described and shown, with reference
to the accompanying drawings.
2. The improved means for securing moveable seats and tailboards of carts and
the like, in position, comprising the arrangement of a pivoted lever such as a,
having a bolt 6 secured to its free end, and a second bolt 61 pivoted at a point pl
between the fulcrum a' and the operating knob a² of the lever a, in combination
with the fixed springs s, s¹, the whole arranged and operating substantially as
herein described and shown, and for the purposes specified.
3/. In mechanism for the securing of seats, tailboards, and the like in position,
such as above claimed, the arrangement of such mechanism within a grooved or
recessed portion of the seat or the like, substantially as herein described and shown,
and for the purposes specified.
