Improved Means for Facilitating the Adjustment of the Seats of
Dog-carts and other Vehicles.
I, GEORGE THOMAS WOOLDRIDGE, of 17, Bromham Road, Bedford, in the County
of Bedford, Gentleman, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improved means for adjusting the seats of dog-carts and
other vehicles.
Seats of this kind as usually heretofore constructed have been provided on the
underside with pins or studs adapted to enter corresponding holes formed in the bars
upon which the seat slides so that, in order to shift the seat, it is necessary to entirely
raise the same and then to shift it several times backwards and forwards to cause it.
to enter the required holes.
The object of my invention is to provide means for shifting the seat more easily than
heretofore and also more quickly.
According to my invention the underside of the seat is provided with projecting
pins or studs as heretofore but these pins, instead of entering corresponding holes are
adapted to slide in slots formed in the bars upon which the seat is supported and
extending the entire length of the same. In order to prevent the seat from shifting
after it has been adjusted I provide beneath the seat a bar or rail adapted to rotate on
its axis which bar or rail carries a series of arms or projections adapted to engage with
When it is desired to move
the projecting pins or pin on the underside of the seat.
the seat the said bar or rail is turned so that the arms or projections thereon are out
of the path of the pins on the said seat so that the latter is free to be moved.
In order to secure the seat it is only necessary to turn the bar or rail in such a
manner that the arms or projections thereon engage with the pins on the underside of
the seat.

COMPLETE SPECIFICATION.
Improved Means for Facilitating the Adjustment of the Seats of
Dog-carts and other Vehicles.
I, GEORGE THOMAS WOOLDRIDGE, of the Castle Hotel, Cambridge, in the County
of Cambridge, formerly of 17, Bromham Road, Bedford, in the County of Bedford,
Commercial Traveller, 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 improved means for adjusting the seats of dog-carts and
other vehicles.
Seats of this kind as usually heretofore constructed have been provided on the
underside with pins or studs adapted to enter corresponding holes formed in the barg
upon which the seat slides, so that in order to move the seat it is necessary to entirely.
raise the same and frequently move it several times backwards and forwards to cause
it to enter the required holes.

page_text: The object of my invention is to provide means for shifting the seat more easily than
heretofore, and to this end my said invention consists essentially in arranging in
conjunction with the bars upon which the seat is supported a series of arms,
projections or teeth with which pins or studs on the underside of the seat are adapted
to engage.
To enable my invention to be fully understood I will describe the same with
reference to the accompanying drawings, in which :-
Figure 1 is a sectional elevation of a dog-cart provided with my improvements:
Figure 2 is a plan of the same; and,
Figure 3 is a rear view.
a indicates the body of the dog-cart, b, b' the seat supporting bars secured to the
sides of the same, and c the seat, which seat on its underside is provided with
blocks d, d. In order to hold the seat in its proper position relatively to the bars, the
latter are preferably provided with ribs e, e, and the blocks d, d are formed with corre-
sponding grooves adapted to fit onto the said ribs, as shewn most clearly in Figure 3.
fff are pins, projections or teeth in conjunction with the bars b, b', the said teeth,
as shewn in Figures 1 and 3, being integral with the bar b. 9, g are the pins or
studs adapted to engage with the said teeth; as shewn, these pins are formed integral
with a shaft carried in bearings or hangers i, i on the underside of the seat, the
forward end of the said shaft being provided with a handle for operating the same,
that is to say, for turning the shaft so that the pins or studs g, 9 can be caused to
engage with or be disengaged from the projections on the bar 6. It is obvious that
when the shaft his turned so that the pins or studs 9, 9 are in the position
indicated by dotted lines in Figure 3, no impediment is offered to the movement
of the seat.
7 is a stop secured to the shaft h and serving to impinge against the underside of
the seat, as shewn most clearly in Figure 3, to prevent the pins from being moved too
far when disengaged from the pins f, f, f.
In order to prevent the shaft from being inadvertently turned by the vibration of
the vehicle or other cause so that the pins or studs g, g become disengaged from the
projections f,f, the said shaft is provided with two flat surfaces against which a
spring m secured to the underside of the seat is adapted to bear, the flat surfaces on
the shaft h corresponding to the locked and unlocked position of the said shaft, so that
the spring serves to hold the shaft, together with its pins or projections in either
position in which it may be placed.
n, n are hooks formed adjacent or integral with the blocks d, d sliding upon
the bar 6, the said hooks serving to prevent the seat from being lifted off the
said bar.
Although in the foregoing description I have referred to the projections f,f being
integral with the bar 6 and the studs or pins g, g secured to the rotating shaft h, it is
to be understood that this order can be reversed, that is to say, that the projections f,f
can be formed upon a hinged bar adapted to engage with fixed pins on the underside
of the seat.
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination with the supporting bars upon which the seat of a dog-cart or
other vehicle is adapted to slide, of a series of pins or projections in conjunction
therewith and pins or studs upon the underside of the seat, the said two sets of pins
being moveable relatively with each other, so that they can be engaged and disengaged,
substantially as, and for the purpose, described.
2. The combination with the seat and seat supporting bars of a dog-cart or other
vehicle, of a series of projections formed upon one or both of the said supporting
bars, and a stud or studs secured to a bar or shaft or bars or shafts mounted in
bearings beneath the said seat in such a manner that the stud or studs can be engaged

page_text: with and disengaged from the projections upon the supporting bar or bars, substantially
as described.
3. The manufacture and use of the improved means for facilitating the adjustment
of the seats of dog-carts and other vehicles, substantially as herein before described
and illustrated in the accompanying drawings.
