I ROBERT WILLIAMS ROBERTS of No 8 Menai Ville Terrace, Menai Bridge, in
the County of Anglesey, Timber. Merchant, do hereby declare the nature of this
invention to be as follows:-
There shall be a plate of Brass or Iron from four to six inches long by about
one inch wide, and shall taper in thickness and be about a quarter of an inch thick
about the middle; and have a rim round the edge so as to admit there being a
hollow from middle to butt end of plate.

There shall be a groove on surface of plate about three fourths its length, and
about " or " of an inch wide or thereabout. There shall be a spring fixed in
the thinnest end of plate and so made as to rise up and down within the groove
when the foot is used to press a little handle made for the purpose at the end of
spring next to butt end.
The Spring shall be so constructed as to have a holder (of a triangular shape
and of sufficient height) at a given distance from top end so that when the spring
is pressed down by the foot this holder shall also go down and will rise up again
with the spring as required and will act as a holder to an open door-the wedge
shape of plate preventing the door to go too far in the other direction.
This plate shall be fixed with screws on a floor at a convenient spot for the door
when open to reach same.

I ROBERT WILLIAMS ROBERTS, of No 8 Menai Ville Terrace, Menai Bridge, in the
County of Anglesey, Timber Merchant, do hereby declare the nature of my inven-
tion for HOLDING OPEN SPRING DOORS AND OTHER DOORS SUCH AS HALL DOORS
& THE LIKE and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:—
R. S. T. shall be a plate of Brass or Iron from four to six inches long and about
one inch wide, tapering in thickness, and shall be about a quarter of an inch thick
about the middle of length. This plate shall have a tapering rim F. G. H. so as
to allow the same to be hollow in the direction R. S. T. B. and shall be about & of
an inch high at the end B. There shall be a groove a. b. in the plate R. S. T.
of about three fourths its length, & shall 'be about of an inch or about 1/8 of an
inch wide.
There shall be fixed at E a strong spring d. d. three fourths (or about) the length
of groove a. b. & running in the groove so as to raise up & down, and to have a
foot handle F by means of which the same will affect the spring up & down when
pressed by the foot at F.
There shall be fixed on the spring d. d. and to be part of same, a holder G of the
triangular shape shown in drawing, of sufficient height, so that the same shall rise
up & down with spring d. d. when the foot is applied at F. When G is pressed
down at F into the groove a. b. it will admit of the door X Y Z. when it is
required to be kept open, to pass over G and when the foot is taken off at F the
spring will cause the holder G to rise up again, & will so catch the door as to hold
it open.
The plate R. S. T. shall be fixed down with screws c. c. on a floor at a convenient
spot so that the bottom of door shall reach same when open, & it is suggested that
in cases where necessary in order to make the holder work well, the flooring boards
should be sunk as required.
One other reason for having this plate tapering is to prevent the door opening
too far towards B.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
1. That when fixed properly to suit the door this is a simple & effectual means
of holding a door open.
2. That it is preferable to the old methods of holding doors open by means of
cabin hooks'screwed' to the door frames.
3. That the tapering shape of the plate performs the two-fold service of
preventing the door going backwards or forwards unless required.
Dated this 30th day of March 1886.
