Improvements in the Fittings of Adjustable Seats for Dog-carts
and like Vehicles.
We, FRANKLIN DAVIES, trading as S. Mills and Company, of 8 Ryland Street,
in the City of Birmingham, Manufacturer, and ALFRED GEORGE GILES, also of
8 Ryland Street aforesaid, Brassworker, do hereby declare the nature of this
invention to be as follows:-
Our invention pertains to the fittings of adjustable seats for dog-carts, traps and
like road vehicles, and consists in improved means for releasing and holding the
seats from and in any adjusted position and also in automatic means for shooting
the bolts into their locking positions.
In carrying out one form of our invention, the underside or ends of the seat are
fitted with supporting brackets or plates through which an axis or shaft, having a
releasing handle at one end, passes. This said shaft runs laterally under the said
seat and is provided at its middle part with a double armed lever or a double
cranked lug, cross piece or the like, to the ends of which, the inner ends of sliding
bolts are jointedly connected. These said bolts, which work within suitable guides
and run in the longer direction of the seat, engage into a pair of two series of holes
formed within seat-rest ledge fittings or plates attached to the two opposite inner
sides of the body of the vehicle.
These rest plates upon which the seat slides are channelled or trough sunken, or
are rabated, and into which the upright or vertical webs of the angle fittings
secured to the two opposite ends of the seat take, so that the said seat besides
sliding upon the rests, also braces the sides of the vehicle together by the angle
fittings at its ends taking into the longitudinal channels of the rests.
The axis or shaft has made fast upon it, a duplex or winged lug, curved or
shamfered at its ends, and preferably flat upon its underside, and upon which the
free end of a flat or other suitable spring bears, and automatically takes the bolts
home and keeps them in their locked positions.
Assuming that the handle is turned and the axis to which it is connected is
partly rotated, the double armed lever is also turned through a short angle and
the bolts are withdrawn in unison and slid back within their guides in opposite
directions, and at the same time the free end of the spring is bent outwardly and
the wing lug is turned nearly at right angles. By releasing the handle, the bolts
are automatically taken back to their normal or shot positions by the pent-up
energy of the spring pressing back the winged lug, whose normal position is
horizontal, so that as the tendency of the spring is to force the wing lug to take a
horizontal position, so the axis and its cognate parts, are compelled also to return
to their normal positions.
Assuming that the ends of the bolts impinge upon the striking plates of the
rests in which the holes are made, then the pulling of the seat makes the bolts
self-finding.
We might add that by the flanged webs taking at the back of the opposite seat
rests, the seat admits of being raised vertically without trouble.
In a further form of our invention, the double armed levers may be made in the
form of a bifurcated crank or cranks, whilst the self-locking lug of the mechanism
may be made of two arms instead of a single one and be provided with a roller or

page_text: rollers which will receive the pressure of the spring. We also propose that the
re-action lug sbould have a stop so that the movement of the handle may be in one
direction only.

Improvements in the Fittings of Adjustable Seats for Dog-carts
and like Vehicles.
We, FRANKLIN DAVIES, trading as S. Mills and Company of 8 Ryland Street,.
in the City of Birmingham, Manufacturer and ALFRED GEORGE GILES also of
8 Ryland Street aforesaid, Brassworker, 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 :-
Our invention pertains to the fittings of adjustable seats for dog-carts, traps and
like road vehicles, and consists in improved means for mounting and releasing and
holding the seats from and in any adjusted position relative to the axle of the
vehicle in which it may be placed for the purpose of balancing, and also in
automatic means for shooting the bolts into their locking positions.
In carrying out one form of our invention, the seat is fitted with supporting
brackets or plates through which an axis or shaft, having a releasing handle at one
end, passes. This said shaft runs laterally under the said seat and is provided at
its middle part with a double armed lever or a double cranked lug, cross piece or
the like, to the ends of which, the inner ends of sliding bolts are jointedly
connected. These said bolts, which work within suitable guides and run in the
longer direction of the seat, engage into any pair of two series of holes formed
within seat-rest ledge fittings or plates attached to the two opposite inner sides of
the body of the vehicle.
These rest plates, upon which the seat slides, may be channelled trough sunken,
or rabated, and into which the upright or vertical webs of the angle fittings
secured to the two opposite ends of the seat take, so that the said seat besides
sliding upon the rests, also braces the sides of the vehicle together by the angle
fittings at its ends taking into the longitudinal channels of the rests.
The axis or shaft has made fast upon it, a duplex or winged lug, curved or
shamfered at its ends, and preferably flat upon its underside, and upon which the
free end of a flat or other suitable spring bears, and automatically takes the bolts
home and keeps them in their locked positions.
Figure 1 of the accompanying drawings represents a perspective view of the
underside of a movable trap-seat fitted with our releasing and locking mechanism.
Figure 2 represents a part cross section of the trap showing the mechanism for
releasing and locking the seat partly in longitudinal vertical section and partly in
elevation and in a locking position.
Figure 3 represents a like section of the mechanism but in an unlocked or
releasing position.
Figure 4 represents an underside plan of the seat and mechanism upon the same
scale as Figures 2 and 3.
Figure 5 is the stop for limiting the shoot of the bolts, separately.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.

through the ends d', of shooting bolts d, take on the locking of the seat e, in any
adjusted position. One of each of the webs of the cross head c³ of the T-sectioned
plates rests upon the side rails whilst the other overhangs the said rails. The ends
of the underside of the seat e, are each fitted with a fixed L-shaped angle strip f,
with the depending web f', taking into a longitudinal groove b', in each of the top.

T sectioned plate c.
h are brackets secured to undersides of the ends of the seat wherethrough the
ends of the bolts d, slide and are guided to the holes in the T-plates by the
tongues /¹.
The inner ends of the bolts d, are jointedly connected at d², to a double armed
lever or double crank g, made fast to a shaft i, carried in bearings j, j', affixed to
the underside of the seat e, and rotated by a handle or turn k. m is a stop for-

rollered end n¹, the free termination of a spring o, whose other end o' is secured to.
the trap seat.
Assuming that the handle is turned and the axis to which it is connected is.
partly rotated, the double armed lever is also turned through a short angle and the
bolts are withdrawn in unison and slid back within their guides in opposite-
directions, and at the same time the free end of the spring is bent outwardly and
the wing lug is turned nearly at right angles. By releasing the handle, the bolts
are automatically taken back to their normal or shot positions by the pent-up.

horizontal, so that as the tendency of the spring is to force the wing lug to take a
horizontal position, so the axis and its cognate parts, are compelled also to return:
to their normal positions.
Assuming that the ends of the bolts impinge upon the striking plates of the rests
in which the holes are made, then the pulling of the seat makes the bolts.
self-finding.
We might add that by the flanged webs taking at the back of the opposite
seat rests, the seat admits of being lifted for removal from the trap without
trouble.
Instead of shooting the bolts by a spring bearing upon a wing lug of the shaft,.
we may employ coiled springs surrounding the bolts and with their ends respectively
bearing against shoulders on the bolts and brackets carried by the seat, and in.
order to ensure the bolts moving in a straight line jointed links inay be interposed
between their inner ends and the points of their connection with the lever g.
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
First. In adjustable and sliding seats for dog carts and like vehicles, lockingland
releasing the same to and from the opposite sides of the vehicle body by double
bolts, worked in unison by a double-armed lever or double crank turning with a
shaft carried in suitable bearings on the seat and fitted with a handle or turn,
substantially as described and set forth.
Secondly. In adjustable and sliding seats for dog carts and like vehicles locking
and releasing the same to and from the vehicle sides, by the mechanism described
and represented, with or without the stop arrangement.
Thirdly. Mounting the adjustable seats of dog carts and like vehicles upon T
or equivalent sectioned plates carried by the vehicle sides in conjunction with
overhanging fittings carried by the seat and engaging with channels or grooves

page_text: in the side rails or equivalent part, whereby the sides of a vehicle are braced or
tied through the medium of the seat, substantially as described and set forth.
Fourthly. In the fittings of adjustable seats for dog-carts and like vehicles, the
general construction, arrangement and combination of the parts substantially as
described and set forth.
