PROVISIONAL SPECIFICATION.
Buffer for the Hinged Covers of Carriage Roof Lamps.
I, ALFRED GEORGE SPENCER of 77 Cannon Street in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
Roofs of carriages such as railway coaches are made with openings to receive
lamps for lighting the interiors of the vehicles which lamps are furnished with
hinged covers. My invention has reference to the use in conjunction with each of
such hinged covers of a buffer such as hereinafter described, on to which the
cover when hastily opened will descend so as to obviate injury to the cover and
roof and the noise incidental to existing arrangements.
For this purpose I secure to the roof in such a position as to receive and arrest
the cover when it is thrown open, a buffer made of india rubber.
In general form my buffer as seen in plan may be square, round, oval or of
other suitable shape; it is moulded with legs or supporting parts extending below
the general level of the under surface of that part against which the cover when
opened will strike; the said legs or supporting parts have made through them
holes for the passage of suitable fastening devices such as screws whereby the
buffer is fixed to the roof.

COMPLETE SPECIFICATION.
Buffer for the Hinged Covers of Carriage Roof Lamps.
I, ALFRED GEORGE SPENCER of 77 Cannon Street, in the City of London,
Engineer, 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 :-
Roofs of carriages such as railway coaches are made with openings to receive
lamps for lighting the interiors of the vehicles which lamps are furnished with
hinged covers. My invention has reference to the use in conjunction with each of
such hinged covers of a buffer such as hereinafter desoribed, on to which the cover
when hastily opened will descend so as to obviate injury to the cover and roof and
the noise incidental to existing arrangements.
For this purpose I secure to the roof in such a position as to receive and arrest
the cover when it is thrown open, a buffer made of india rubber.
In general form my buffer as seen in plan may be square, round, oval or of
other suitable shape; it is moulded with legs or supporting parts extending below
the general level of the under surface of that part against which the cover when
opened will strike; the said legs or supporting parts have made through them
holes for the passage of suitable fastening devices such as screws whereby the
buffer is fixed to the roof.
In the accompanying drawings,
Figs. 12 and 3 are respectively a cross section, a plan and a side view of a
buffer constructed according to this invention.
Fig. 4 is a diagrammatic view showing the application of such a buffer to the
roof of a railway coach for the purpose mentioned.

page_text: The buffer shown consists of a block of india rubber of square shape in plan
and formed at its underside with two grooves or channels 1 and 2 arranged at
right angles to each other so as to form at the corners legs or supports 3 that
serve to carry the upper part 4 of the buffer above the roof 5 of the railway
coach to which it is secured so that such part will be able to act effectively as
a buffer to receive the blow of a hinged lamp cover 6 when the same is hastily
thrown open. Each leg or support 3 has formed through it a hole 7 for the
reception of a screw by which the buffer can be fixed in the required position to
the coach roof. The upper portion of the buffer may advantageously be cut away
at the corners above the holes 7 as shown at 8. The sides of the buffer may if
desired be surrounded by a closely fitting rectangular metal frame designed to
prevent the india rubber being damaged.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
A buffer for the hinged cover of a carriage roof lamp consisting of a block of
india rubber moulded with legs or supports extending below the general level of
the undersurface of that part of the block against which the lamp cover when
opened will strike and formed with holes for the passage of suitable fastening
devices such as screws by which the buffer can be fixed to a carriage roof
substantially as described with reference to the example shown in the drawings
annexed.
