PROVISIONAL SPECIFICATION.
A Burglar Proof Window and Door Protector.
WILLIAM BAGGALY OSBORN 10 and 11, Buckingham Street Birmingham
Manufacturer of Steel, and Iron Fire Shovels etc. do hereby declare the nature
of this invention to be as follows:-
The object of this my invention is to prevent windows & doors being forced
open by burglars. In carrying out my invention 1 construct a flat plate with screw
hole or holes therein, or otherwise, on this flat plate at one end, I raise two ears
thereon, with a hole through their centre-I form a tongue or lever with a broad
knif like face, at one end, tapering to a tail like point, at the other. The middle
I fix the tongue
of this tongue is shouldered, & a hole pierced through the centre.
between the two ears upon the flat plate, & rivet them together allowing the tongue,
or lever, to act freely. This forms the protector. In working position I screw a
protector, on each end, of the top flat of the lower sash of a window, so that the
broad face of the knif shall rest against the rebate of the window frame, or
against the upper sash of the window, & if a burglar attempts to force open the
window from the outside the broad face of the knif is driven into the woodwork
& makes it impossible to open the window-but from the inside the tail pointed
end of the protector can be tilted by the finger & the protector thrown out of
action.
When I use the protector, to prevent a door from being forced open the flat
plate of the protector underneath is provided with a spike-I push the spike into
the floor & place the broad face knif of the tongue against the door.
It is understood, I shall adopt any mere modification required in carrying out
my invention, the protector may be made in various ways & forms, such as a hinge,
with knuckles, & flaps, but one flap of the hinge without screw holes therein, &
this flap jagged or otherwise. Again the flat plate of the protector may be riveted
upon another plate, so as to swing round. The tongue of the protector, may be
formed without a pointed tail--the ears on the flat plate, being made with stops or
shoulders thereon. The protectors may be made in any kind of metal, or material
required such as iron, brass, etc.

COMPLETE SPECIFICATION.
A Burglar Proof Window and Door Protector.
WILLIAM BAGGALY OSBORN 10 and 11 Buckingham Street Birmingham
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 aud by
the following statement :-
The object of this my invention is to prevent windows & doors being forced
open by burglars. In carrying out my invention, I construct a flat plate, with

page_text: screw hole, or holes therein, or otherwise-on this flat plate, at one end, I raise two
ears thereon with a hole through their centre.
I form a tongue or lever with a broad knife like face, or serrated face, at one
end, tapering to a tail like point at the other, or fan, or serrated, points,―the middle
of this tongue, is shouldered, & a hole pierced through the centre.
I fix the tongue, between the two ears, upon the flat plate, & rivet them together,
allowing the tongue, or lever, to act freely-this forms the window, & the tongue,
or lever, by itself, may act as the door protector, & also as a window protector.
In working position-I screw the window protector, on each end of the top flat
of the lower sash of a window, so that the broad face of the knife or serrates thereof
shall rest against the rebate of the window-frame or against the upper sash of the
window, & if a burglar attempts to force open the window from the outside the
broad face of the knife or the serrates thereof are driven into the woodwork, &
makes it impossible to open the window-but from the inside, the tail, or fan
pointed end, of the protector, can be tilted, by the finger & the protector thrown
out of action-or otherwise moved. When I use the protector to prevent a door,
from being forced open, the flat plate, of the protector underneath is provided
with a spike, I push the spike into the floor, & place the broad face knife, or
serrates thereof of the tongue, against the door, at an angle of about 45 degrees-
or the tongue, or lever, serrated at both ends, may act-without, the flate plate,
against the door, or window frame.
I will now proceed to describe with reference to the accompanying drawings,
the manner in which my burglar proof windows, & door protector, is to be
performed.
Fig. 1. represents the flat plate, with its screwed holes & its two raised ears
thereon, & their central holes to receive the rivet, for bearing & carrying the spiked
& fan tail tongue, or lever.
Fig. 2. represents a plan of the spiked or serrated fan tail tongue, or lever to be
fitted, & to be worked inside the plate of Figure 1.
Fig. 3. represents another plan, of the tongue, to be fixed against the floor &
the door, as seen in section of Figure 7. & without the plate, but both ends serrated,
so as to get a firm grip against the door & the floor should the door be forced
open.
Fig. 4. represents the plate & tongue jointed together, by the rivet passing
through the ears of the flat plate, & the bent sides, of the lever. This view shews
the protector, ready to be attached to the window.
Fig. 5. represents the plan of the protector, with the tongue, or lever, with the
narrow pointed tail & the broad knife like face.
Fig. 6. represents my burglar proof, window protector screwed upon the top of
the lower frame, of the sash, & the tongue or lever with its teeth resting against
the upper frame of the sash-& in this position, the window is prevented from
being opened from the outside, & should a burglar try to force the window frame
down the teeth are driven into the woodwork.
Fig. 7. represents a sectional view of the tongue as the protector, in position,
on the floor, & resting against the door, to prevent the same, from being forced
open, if so tried, the spikes at both ends would enter the floor & the door.
