COMPLETE SPECIFICATION.
Improvements in Tramcar or Omnibus Seats, Garden Chairs, and
the like.
1, JOHN JACKSON, of 4, Borrage Terrace, Ripon, in the County of York, Tanner,
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 relates to improvements in tram car or omnibus seats, garden
chairs and the like, the object being to shield or cover them with water-proof
coverings either automatically or by hand so as to prevent them getting wet,
in rainy or snowy weather. I will now proceed to describe my invention by the
aid of the accompanying illustrative drawings, in which; Fig. 1 is a side eleva-
tion of a tram-car seat according to my invention; Fig. 2 is a front view thereof;
and Fig. 3 is a detail hereinafter referred to.
The back of the seat is carried by side arms 1 and 1ª arranged one on each
side of the seat and mounted to oscillate on studs 2 secured in the crossbars 3;
each of the side arms 1, 1ª has secured to it at a certain distance from their
fulcrums, a stud 4, 4" which takes into and works in a slot 5, 5" provided in the
lower end of a rocking lever 6, 6ª, which levers oscillate on gudgeons 7 and 7"
mounted in bearings 8 and 8 provided in the cross bars 9 and 9" secured to the
main frames 10 and 10. In the upper ends 11 and 11" of the rocking levers is
secured a cross bar 12 to which one end 13 of a cover 13" preferably of water-
proof material, is secured by means of hooks 14 and 14", the other end 15 being
secured to a cross bar 16 secured to the side arms 1 and 1 by being wrapped
round it and sewn thereto; or such end may be furnished with hooks similar to
those on the end 13 and hooked on the cross stay 16.
The extreme lower ends 17 of the rocking levers 6 and 6 are provided with a
cross bar 18 which is secured to them, to which are detachably secured by hooks 19
and 19 spiral springs 20, the other ends 21 of which are also provided with
hooks 22 which are attached to other hooks 23 secured to the lower ends 24 of
the main frames 10, 10" or to hooks 23" secured to the other lower ends 24 of
the main frames 10, 10ª according to the desired position of the back when the
seat is in use. The side arms 1 and 1" instead of being furnished with studs 4
and 4" to take into the slots 5 and 5ª in the levers 6, 6" may conveniently be pro-
vided with slots 25 as indicated in Fig. 3, in which studs secured to the rocking
levers 6 and 6ª may work.
Now on moving the two arms from the position, shown in the drawing on the
left hand, to the position shown in dotted lines on the right hand, the rocking
levers will be moved from the right hand to the left hand side as shown in
dotted lines, taking the water proofed cover with it, and exposing a dry seat, and
also expanding the springs at their lower ends. On a person rising and leaving
the seat these springs pull the rocking levers back to their original position, also
causing the two arms to move back to the starting position, thus automatically
covering the seat, ready for the next person.
When it is desired not to use the automatic return movement, but to uncover

page_text: and cover the seat by hand as required, the springs are dispensed with. When
it is desired to change the position of the cover, to use the chair the reverse way,
the cover is unhooked from the cross bar of the rocking levers and the two springs
(if such are provided) from their hooks on one side and the side arms are moved
to the other side; the cover is then placed over the seat and again hooked to the
cross bar, and the springs secured to the hooks on the other side of the frame,
when it is ready for use.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is;-
1. In tram car or omnibus seats, garden chairs or the like the combination of
a lever arrangement operated in one direction by hand through the oscillating
side arms of the back and in the other by springs with a waterproof cover for
automatically covering or shielding the seat substantially as illustrated and
described.
2. In tram car or omnibus seats, garden chairs or the like the combination
with the oscillating side arms of the back, of a lever arrangement and a seat
cover connected to the said levers and to the back, substantially as illustrated and
described.
3. Tramcar or omnibus seats, garden chairs and the like provided with means
for covering or shielding them constructed, arranged and operating, substantially
as described with reference to and illustrated in the accompanying drawings, the
same being adapted to operate automatically or not.
Dated this 20th day of May 1899.
