I, ROBERT SMITH MUSHET of 29 Leinster Square Bayswater Barrister at law do
hereby declare the nature of this invention to be as follows:-
My invention consists of a new mode of opening carriages in such a manner that
when closed they will be able to sustain a considerable weight of luggage, and is
equally applicable whether it is desired to render the back or front part of the carriage
capable of being opened, or whether the carriage be two or four wheeled.
I make the upper part of the front or back panel of the carriage, as the case may
be, or in the case of a wagonette cach of the side panels, movable upon a hinge across
the middle thereof or thereabouts. Upon each of the side edges of such movable
panel is a groove or slot, in which engages a pin or stud, fixed to the inner side and
near the top of each of the panels which are injuxta position to the said movable
panel. Each of such last mentioned panels is divided by me into two parts, and is so
made that the upper part, together with the top of the carriage to which it is affixed,
will turn back upon a joint in the frame immediately above the door of the carriage,
and will pass over and outside the lower part, carrying with it the first-mentioned
movable panel, until the pin or stud has again travelled to the extremity of the groove
or slot above mentioned, when it will remain at rest.
The principle I have adopted is that, given two eccentric circles of unequal diameter,
the one having its centre at the above mentioned joint and as radius a line drawn from
such joint to the said pin or stud, and the other having its centre at the above
mentioned hinge and as radius a line drawn from such hinge to the said pin or stud,
(in other words, the side of the first mentioned movable panel,) with their
circumferences intersecting at such pin or stud, if they are turned in conjunction
upon their respective axes, the pin or stud will travel backwards and again forwards
along the slot or groove until their circumferences again intersect, when it will
have again reached the extremity of such slot or groove and will remain at rest.

Invention for Improvements in the Manufacture of Carriages.
I, ROBERT SMITH MUSHET of 29 Leinster Square, Bayswater, Barrister at Law 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 consists of a new mode of opening carriages in such a manner that
when closed they will be capable of sustaining a considerable weight of luggage, and
is equally applicable, whether it is desired to render the back or the front part
of the carriage capable of being opened, or whether the carriage be four or two-
wheeled.
I make the upper part of the front or back panel of the carriage, as the case may
be, or in the case of a wagonette each of the side panels movable upon a hinge across
the middle thereof or thereabouts. Upon each of the side edges of this moveable
panel is placed a groove or slot as shown in the drawing Fig. 1, in which engages a
pin or stud fixed to the inside and near the top of each of the panels which are in
Each of such last mentioned
immediate juxtaposition to the said movable panel.
panels is divided by me into two parts and is so made that the upper part, together
with the top or roof of the carriage to which it is affixed, will turn back upon a joint
in the frame immediately above the door of the carriage, and will pass over the lower
part, carrying with it the first mentioned movable panel, until the stud or pin has
again travelled to the extremity of the groove or slot above mentioned when it will
remain at rest.
Figure 2 represents the back part of an ordinary four wheeled carriage to which my
invention has been applied. The back panel has a hinge across it at A upon which
the upper part is free to work; and such upper portion has a groove or slot upon the
sides thereof as above described. Each side panel is divided into two parts on the
line A to B and is 50 made that the upper part slightly protrudes beyond and can
pass over the lower part. There is a strong joint at B in the frame of the carriage
immediately above the door. On the inside of each of the side panels in the position
indicated by the letter is a stud or pin engaging in the groove or slot above-
mentioned. I place a spring lock on the back panel, locking into the top of the
carriage and worked by a small handle or ring. By unlocking the lock and pulling
the handle or ring the head or upper part of the carriage will descend into the position
represented in the drawing by the dotted lines, and the pin or stud having again
reached the extremity of the groove or slot, it will descend no further, but will remain
suspended upon the hinge and joint. In order, however, to relieve the strain I prefer
to allow it to rest upon the rods or bars which unite the back springs to the body of
the carriage, placing thereon a small rubber cushion to prevent bruising. Figure 3
represents the back of a wagonette to which my invention has been applied.

page_text: The principle I have followed is, that given two eccentric circles of unequal
diameter, the one having its centre at B and as radius a line drawn from B to C, and
the other having its centre at A and as radius a line drawn from A to C, their
circumferences intersecting at C, if they are turned in conjunction upon their
respective axes the stud or pin will travel backwards and again forwards along
the groove or slot, until their circumferences again intersect, when it will have
again reached the extremity of the groove or slot, and will remain at rest.
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
The combination, for the purpose of opening carriages as above described, of
movable panels turning upon different axes, but in conjunction through the
operation of the pin or stud and the groove or slot.
