Improvements in or relating to Movable Arm and Head Rests
Combined, applicable to Railway Carriages, Tram-cars, Ships'
Berths, and other Seats.
1, FREDERICK ATTOCK, of Fernyhurst, 131 Palatine Road, near Manchester,
Engineer, do hereby declare the nature of this invention to be as follows:-
In the Specification of a former Patent granted to me under date the
16th December 1890, No. 20,490 is described and claimed an arm rest and head
rest combined, so constructed and arranged that when the arm rest is not required
for use it may be turned up and when this is done the head rest will through a
suitable connection be simultaneously raised to a position clear of the occupant of
the seat to which my said invention is applied. Now my present invention has
reference to the improvements in such arm rest and head rest combined which I
will now proceed to indicate. I still retain the principle of operating the head
rest from the arm rest through a suitable connection between the arm rest and the
slide of the head rest but according to my present invention there is combined
with the arm rest the movable head rest and its slide a device of the kind
commonly known as lazy tongs arranged on a fixed pivot at a point between the
upper and lower extremities; one end of the tongs is suitably connected to the
slide or movable head rest, by a link or otherwise, while at the other end the tongs
are connected to the said movable arm rest by a suitable hinge.
The arrangement is or may be such that a given extent of movement of the
lower end of the tongs in a vertical sense will impart a considerably larger extent
of movement to the upper end of the tongs and consequently to the head rest.

COMPLETE SPECIFICATION.
Improvements in or relating to Movable Arm and Head Rests
Combined, applicable to Railway Carriages, Tram-cars, Ships'
Berths, and other Seats.
I, FREDERICK ATTOCK, of Fernyhurst, 131 Palatine Road, near Manchester,
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:-
In the Specification of a former Patent granted to me under date the
16th September 1890, No. 20,490 is described and claimed an arm-rest and head-rest
combined, so constructed and arranged that when the arm-rest is not required for
use it may be turned up and when this is done the head-rest will through a suitable
connection be simultaneously raised to a position clear of the occupant of the seat
to which my said invention is applied. Now my present invention has reference
to the improvements in such arm-rest and head-rest. combined which I will now
proceed to indicate. I still retain the principle of operating the head-rest from the
arm-rest through a suitable connection between the arm-rest and the slide of the
head-rest, but according to my prosent invention there is combined with the arm-
rest, the movable head-rest, and its slide, a device of the kind commonly known as
lazy tongs arranged on a fixed pivot at a point between the upper and lower
extremities. One end of the tongs is suitably connected to the slide or movable

page_text: head-rest, by a link or otherwise, while at the other end the tongs are connected to
the said movable arm-rest by a suitable hinge.
The arrangement is or may be such that a given extent of movement of the
lower end of the tongs in a vertical sense will impart a considerably larger extent
of movement to the upper end of the tongs and consequently to the head-rest.
In the accompanying drawings,
Fig. 1 is a vertical section of a movable head-rest and arm-rest combined
according to this invention, and specially suitable for use in a railway carriage, the
parts being shown in their lowered position ready for use.
Fig. 2 is a similar view to Fig. 1 but shewing the parts in their raised positions.
Fig. 3 is a back view, the parts being in the position shown in Fig. 1.
For the sake of clearness the usual upholstering is not shown on the drawings.
The arm-rest 1 is pivoted at 2 to the framework 2ª of the carriage, and to its
upper or rear side is attached by means of a suitable hinge 3 a sliding back 4 which
is provided with suitable guide pins 5 arranged to work in guide ways 6 formed in
the said frame work. The head-rest 7 is carried by a slide 7 arranged to work
vertically in fixed guides or grooves 8. The head-rest is connected with the arm-
rest according to this invention by means of lazy-tongs 9, which are mounted on a
fixed pivot 10 secured in a cross bar 11 of the frame-work and is located between
the upper and lower ends of the lazy tongs. The upper end of the lazy tongs is
connected to the sliding or movable head-rest by means of a link 12 and a pin 13
which projects from the rear side of the slide 7 through a slot 14 formed in the
seat back. The lower end of the lazy tongs is hinged or jointed at 15* to one end
of a curved metal plate 15 the other end of which is hinged or jointed at 15 to a
plate 16 secured to a block 17 attached to the rear side of the sliding back 4. The
two plates 15 and 16 together form a hinge one leaf or part of which is much
larger than the other.
The arm-rest is provided with lateral pins or projections at 1" which work in
grooves 18 formed in the frame-work, and serve as a stop to limit the movement of
the arm-rest by coming into contact with suitably arranged abutments.
In the example shown, the lower arms or links of the lazy tongs are made shorter
than the upper ones, so that a given extent of movement of the lower end of the
lazy tongs, in a vertical sense, will result in a considerably larger extent of
movement of the upper end of the tongs and consequently of the head-rest 7
connected therewith."
By the arrangement described it will be readily understood that, in turning the
arm-rest from the position shewn in Fig. 1 to that shewn in Fig. 2, the lazy tongs
will be extended and the head-rest consequently moved out of the way of a person
desiring to sit beneath it, and that upon again moving the arm-rest into the position
shewn in Fig..1, the head-rest will automatically return into the position shown in
that figure.
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:-
1. A movable arm and head-rest in which there is combined with the arm-rest,
and the movable head-rest and slide, a device of the kind known as lazy tongs
mounted on a fixed pivot at a point between its upper and lower extremities
substantially as herein described for the purpose specified.
2. The combination and arrangement of parts constituting the improved movable
head-rest and arm-rest combined substantially as described and shewn.
