Improvements in Shaft or Handle Attachments Applicable to Hand
or other Carts and Carriages and for similar Purposes.
I, HARRY CARTWRIGHT of 154 Victoria Road, Scarborough, in the County of
York, Ironmonger, do hereby declare the nature of this invention to be as
follows:-
My invention is intended to provide a ready means of adjusting the inclination of
the shafts or handles of hand or other carts or carriages and is so constructed, that
within certain limits the angle of such handles or shafts may be readily changed.
At the same time my invention allows the handles or shafts to be securely fixed in
their changed position with the greatest ease and the least possible delay. I may
apply it to any carriages where it is desired to change the position of such handles
or shafts or for other similar purposes; but I find it more particularly convenient for
use in children's mail carts or go-carts.
The height of the shafts of such carriages is adjusted to suit children, and when
adults use them as is now extensively done by nurses and mothers it is found that
the carts are inconveniently inclined or tipped up and the back seat is rendered
practically useless, so that no child can comfortably sit upon it.
By using my invention the shafts may be inclined so as to keep the carriage or
cart level when a taller person draws it.
In carrying my invention into effect I hinge the shaft to be made adjustable and
secure firmly upon each side of the hinge a plate with a projecting screw stud and
one or more pins. The pins and studs are so placed that a circle drawn with the
hinge as centre, passes through their centres. Upon these studs I place a flat ring or
plate perforated with any required number of holes to fit the screwed studs and pins,
and secured firmly in place on the studs or pins by two thumb or wing, or other
nuts or fastenings.
In one position of the ring the shaft or handle is horizontal and is firmly held
there by the fit of the screwed studs and pins in the holes.
When the angle is required to be changed I unscrew the nuts and lift the ring off
the studs and pins, then move the shaft upon its hinge to the desired angle and
drop the plate or ring in position so that other holes in the plate or ring fit the
studs or pins at one side of hinge; the stud and pins in the other side fit into
the same hole as before.
By arranging a suitable number of holes I can alter the angle of the handles to
any desired extent while securing complete reliability and firmness in any of the
positions by screwing down the nuts or fastenings above the perforated plate
or ring.
I prefer to use one screw stud and two pins in each of the fixed plates; but one
screw stud and one pin are sufficient in some cases. Where the shafts are large and
heavy it is desirable to use more than one screw stud and more than two pius in each
fixed plate, and sometimes I even use more than one fixed plate on each side of the
shaft hinge; this I can do without departing from the essential feature of my
invention.

Improvements in Shaft or Handle Attachments Applicable to Hand
or other Carts and Carriages and for similar Purposes.
I, HARRY CARTWRIGHT, of 154 Victoria Road, Scarborough, in the County of
York, Ironmonger, 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 is intended to provide a ready means of adjusting the inclination of
the shafts or handles of hand or other carts or carriages, and is so constructed that
within certain limits the angle of such handles or shafts may be readily changed.
At the same time my invention allows the handles or shafts to be securely fixed in
their changed position with the greatest ease and the least possible delay.
I may apply it to any carriages where it is desired to change the position of such
handles or shafts; or for other similar purposes but I find it more particularly
convenient for use in childrens mail carts or go-carts.
The height of the shafts of such carriages is adjusted to suit children and when
adults use them, as is now extensively done by nurses and mothers it is found that the
carts are inconveniently inclined or tipped up and the back seat is rendered practi-
cally useless, so that no child can comfortably sit upon it.
By using my invention the shafts may be inclined so as to keep the carriage or
cart level when a taller person draws it.
In carrying my invention into effect, 1 hinge the shaft to be made adjustable, and
secure firmly upon each side of the hinge, a plate with a projecting screw stud, and
one or more pins.
The pins and studs are so placed that a circle drawn with the hinge as centre,
passes through their centres. Upon these studs I place a flat ring or plate perforated
with any required number of holes to fit the screwed studs and pins, and
secured firmly in place on the studs or pins by two thumb or wing, or other nuts or
fastenings.
In one position of the ring the shaft or handle is horizontal, and is firmly held there
by the fit of the screwed studs and pins in the holes.
When the angle is required to be changed, I unscrew the nuts, and lift the ring
off the studs and pins, then move the shaft upon its hinge to the desired angle, and
drop the plate or ring in position so that other holes in the plate or ring fit the
studs or pins at one side of the hinge; the stud and pins in the other side fit into the
same holes as before.
By arranging a suitable number of holes I can alter the angle of the handles to
any desired extent while securing complete reliability and firmness in any of the
positions, by screwing down the nuts or fastenings above the perforated plate
or ring.
I prefer to use one screw stud and two pins in each of the fixed plates; but one
screw stud and one pin are sufficient in some cases.
Where the shafts are large and heavy it is desirable to use more than one screw
stud and more than two pins in each fixed plate, and sometimes I even use more than
one fixed plate on each side of the shaft hinge; this I can do without departing from
the essential feature of my invention.
In order that my invention, and the method of carrying the same into effect may
be more readily understood, Í hereunto append one sheet of explanatory drawings to
be hereinafter referred to.
Figure 1 is an elevation and Figure 2 a plan of my improved shaft or handle,
A representing a portion of the adjustable handle, and B a portion of the cart or
carriage to which the handle is attached, by means of the hinge C and the flat plate
or ring D. The handle is shown in a horizontal position in Figures 1 and 2 ; but it
may be readily inclined by my present invention, by releasing or slackening the

page_text: thumb nuts H H and drawing the ring D off the studs F, F, F³, F³, and the
screws G, G', when the handle may be set at the desired angle and secured by
fixing the ring D in position, so that the studs F2, F3 fitting in holes K', K³, and
the screw G¹ fitting in the hole K2, may fit into other holes of the plate D. The
studs F, F¹ do not change their position in the plate ; but fit into the same holes of
it, whether the handle is inclined or in a horizontal position.
Figure 3 is a plan of the plate or ring D showing the disposition of the
holes K', K2, K³, K*, K³ and k¹, k, k³, for the reception of the studs and screws.
Figures 4 and 5 are side and end elevations respectively of the stud plate E.
F, F are the projecting studs, and g the hole, preferably square for the reception
of the screw or bolt G. These studs, and the bolt hole are so arranged, that when
the plate is fixed in position on the shaft or handle, a circle described from the centre
of the hinge, passes through the centres of the studs F, F¹ and also of the bolt hole g.
The small countersunk holes a, a, a, are for the reception of screws for securing the
stud plate in its position. The bolt hole 9 is made preferably square to suit the
square portion of the bolt or screw G, so that the screw may be prevented from
turning round when the thumb nut is operated.
I construct my improved fittings preferably out of metal although I sometimes
make the ring D of wood or other suitable material providing eyelets or metal cases
to the holes for receiving the projecting pins.
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. In hand and other carts and vehicles, the application of an adjustable hinged
handle for the purpose of altering the angle or position of the handle in relation to
the body of the cart.
II. In hand and other carts and vehicles the application of a loose ring such as D
to be held upon projecting studs such as F, F1, F2, F³, together with nuts such
as G, G, as and for the purposes hereinbefore described and substantially as illustrated
in the accompanying drawing.
III. In hand and other carts and vehicles, the application of stud plates such
as E, E¹, together with screws such as G, G', as and for the purposes hereinbefore
described and substantially as illustrated in the accompanying drawing.
