PROVISIONAL SPECIFICATION.
A New or Improved Door Porter or Door Block.
1, GEORGE FREDERICK NEWMAN of the firm of William Newman and Sons of
Hospital Street, Birmingham in the County of Warwick, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention has for its object, the keeping of a door open, or blocking the same
when closed, and consists essentially of a cranked and swinging foot, jointedly con-
nected to a bracket, which when in position, and acting as a door porter, is secured
near the inside edge of a door, and when acting as a door block, is secured to the
outside of a door.
In carrying out my invention, I proceed as follows:-
To a bracket or the knuckles of a bracket, I pivot excentrically or jointedly connect
a foot, which swings or hangs from the said bracket, and with the underside thereof,
mado cam shaped or semi-circular; so that when placed in position, it wedges a door,
and holds it in an open position, and when not required, it is turned up from the
floor, and rests with the tread in an inverted position out of the way.
Thus, the porter or block, is affixed in such a position, that the tread of the foot or
cranked arm wedges on the floor, and blocks the door open, as the pressure of the
door tends to tighten the bite of the foot.
The tread of the foot or arm may be plain, or it may be ratchet serrated, by which
latter, a more determinate grip upon the floor is secured.
The hanging foot may be kept in its acting and neutral positions, by flats upon the
knuckle or inner end, bearing against a spring. Or the spring may be V shaped at
its end, which takes alternately upon the flats of the said joint part. Or instead of
flats, the inner or joint end of the foot may be split, and with snugs on the side
engaging with depressions on the inner faces of the knuckles of the bracket.
The invention is particularly applicable to doors provided with closing springs; and
when the porter as aforesaid is swinging, it is only necessary to open the door, and
loose the same, when it is automatically blocked and held in an open, or an adjusted
position.
When applied as a block, the appliance is simply placed upon the other side of a
door, which when in position, prevents the said door being opened.

COMPLETE SPECIFICATION.
A New or Improved Door Porter or Door Block.
I, GEORGE FREDERICK NEWMAN of the firm of William Newnan and Sons of
Hospital Street Birmingham in the County of Warwick Manufacturer 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 has for its object, the keeping of a door open, or the blocking of a
door open, or the blocking of a door when closed, and consists essentially of a cranked
and swinging foot, jointedly connected to a bracket, which when in position and acting
as a door porter, is secured near the inside edge of a door, and when acting as a door
block, is secured to the outside of a door.

page_text: In carrying out my invention I proceed as follows.
To a racket or the knuckles of a bracket 1 pivot excentrically or jointedly connect
a fool which swings or hangs from the said bracket, and with the undersido thereof,
made cam shaped, or semi-circular; so that when placed in position, it wodges a door
and holds it in an open position, and when not required, it is turned up from the floor,
and rests with the trend in an invertel position, out of the way.
Thus, the porter, or bluck, is affixed in such a position, that the trond of the foot
or cranked arm, wedges on the floor, and blocks the door open, as the pressure of the
door tends to tighten the bite of the foot.
The trend of the foot or arm may be plain, or it may be ratchet serrated, by which
latter, a more determinate grip upon the floor is secured.
The hanging foot may be kept in its acting and neutral positions, by flats upon the
knuckle or inner end, bearing against a spring. Or the spring may be V shaped at
its end, which takes alternately upon the flats of the said joint end. Or instead of
fluts, the inner or joint end of the foot may be split, and with snugs on the side
engaging with depressions on the inner faces of the knuckles of the bracket.
The invention is particularly applicable to doors provided with closing springs ; and
when the porter as aforesaid is swinging, it is only necessary to open the door and
loose the same, when it is automatically blocked and hold in an open or an adjusted
position.
When applied as a block, the appliance is simply placed upon the other side of a
door, which when in position, prevents the said door being opened.
Figure 1 of the accompanying drawing represents a door, provided with my now
or improved door-porter and door block, applied as a door porter.
Figure 2 shows an enlarged, or full sized edge view of the appliance, with parts of
it in section.
Figure 3 is a front elevation of the same.
Figuro is an underside view of the tread of the swinging foot.
Figure 5 shows the swinging foot separately.
Figure 6 the bracket, from which the said swinging foot is suspended.
Figure 7 shows a horizontal section on the dotted lines A B figure 1 thus exhibiting
a door kept open, by the porter.
Figuro & exhibits the a swinging foot, provided with a faced, or yielding tread.
Figure 9 represents a like swinging foot, with an expanding tread.
a is a free swinging foot, or arm, jointed to a stationary bracket, b, by a cross
pina, passing through knuckles b³, disposed at the lower and middle part of the said
bracket, which is secured to a door, by screws.
The tread or underside of the said foot, is ratchet-toothed at a³, and with a hole or
piercing at, directed threngh a portion of the middle of it.
The foot is made cam-shaped upon its lower part, so that the same shall automatically
jamb upon the floor, on a door being released. The bracket bis gapped at the rear of
the joint end of the swinging fool or arm a and is marked bª.
In figure S, a is the swinging foot with a facing of rubber, cork, leather, or like
material, inserted within its underside.
In figure 9, a, is the swinging foot, with an expanding spring troad as, with ratchet
serrations a. These facings are combined only with this swinging foot of the con-
struction as shown.
On the door porter or block not requiring to be used it is turned upwards into the
position as represented in dotted lines, figure 2.
Having now particularly described and ascertained the nature of my said invon-
tion and in what mannor the same is to be performed, I declaro that what I
claim is :-
First. A door porter, consisting of a swing foot, or loosely jointed arm with the
lower or troad part thereof shaped excentric, or wodge curved, substantially as
described and sot forth in figures 1 to 7.

page_text: Secondly. A door porter, consisting of a loosely swinging and jointed arm, with
attachment bracket, and with the underside of the tread of the said arm, serrated, or
ratchet toothed, substantially as sot forth in figures 1 to 7.
Thirdly. Facing the treads of door porters, as herein described, with rubber, cork,
or other yielding materials, as in figures 8 and 9.
Fourthily. A door block, consisting of a loosely jointed arm, with underside or
tread, formed excentric, or cam shaped. substantially as described and set forth.
