Improvements in or connected with Shafts or Handles for Mail
Carts and other Vehicles.
I, EDWARD HAMMERTON 39 Greenwood Road Dalston London N.E. Carpenter,
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 consists in providing a means or device by the use of which the
shafts or handles of mail carts or vehicles may be adjusted to suit the height of the
horse driving same or person.
Referring to the annexed drawings
Figure 1. is a side elevation of a shaft fitted or arranged according to my
invention.
Figure 2. is a plan of same.
Figure 3. is an elevation of a modified arrangement.
a & a' is the shaft, the part a being pivoted at c to the part a'. The plates d
are secured to the part a' by screws p and carry the pivot peg or screw.
pro-
To the part a the hinged plate e is attached by screws for such suitable means.
This plate e has a series of holes 9 for the passage of the pin h. A slot i is
vided to allow the screw bolt j to pass through the plate e. 7 is a plate secured to
the shaft at m. A plate n is secured to the shaft in any convenient manner. The
plates & n have corresponding holes pierced in them for the passage of the pin h.
This pin may be attached to the shaft by means of a chain o if desired.
In the modification shown in Figure 3, the pin is dispensed with and the plate e
is serrated or rack cut at r, and the plate is bent so as to form the point at s for
engaging with the rack r; a spring t being employed to remove the point s from
the rack when the thumb screw u is released which screws on the bolt v. The
plate e is slotted to allow of the passage of the bolt v and spring t.
When it is desired to alter the angle of the shaft, the pin h is removed from the
holes and the adjustment made, when the pin is again inserted, thus retaining the
