Improvements in Catches, Fastenings, and other Furniture for
Windows, Doors, and the like.
We, THOMAS BURGESS, of Thomas Street, Congleton, in the County of Chester,
Engineer, and JOHN JOSEPH BURGESS, of Fox Street, Congleton, aforesaid,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention is designed to provide an improved form of catch or fastener
for windows, doors, cupboards blind cords and similar articles.
It consists essentially in constructing the appliance with a worm mounted to
rotate in engagement with a sliding bolt or bar provided with indentations or teeth
by which it is propelled to and fro by the worm.
For window catches the sliding bolt or bar is preferably made with notches with
which the worm engages. The worm is mounted in a bracket in which the bolt
A hasp or staple is provided to receive
or bar is capable of sliding to and fro.
the end of the bolt and this is fitted with a stop at or near the back edge against
which the end of the bolt or bar abuts to jamb or hold the window sashes apart
and prevent rattling.
For window blind cords the bolt or bar is made longer so as to have sufficient length
of travel and is fitted at its upper end with a knob or pulley over or around which
the cord of the blind passes. The tension of the cord is adjusted by moving the
bar or bolt up and down by the worm.
For cupboard door catches or fasteners the appliance may be made very similar
in size and shape as for a window fastener.
For door bolts or the like the bolt or bar is made of any desired length or size
and of rectangular or cylindrical shape with teeth or notches with which the
worm engages.
A fastener or catch so constructed will be very easy to operate but from the
outside of a window or door could not be moved by the insertion of any tool.

. Improvements in Catches, Fastenings, and other Furniture for
Windows, Doors, and the like.
We, THOMAS BURGESS, of Thomas Street, Congleton, in the County of Chester,
Engineer, and JOHN JOSEPH BURGESS, of Fox Street, Congleton, aforesaid,

page_text: 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:-
This invention is designed to provide an improved device for fastening windows,
casements, cupboards blind-cords and similar articles.
It consists essentially of a sliding bolt or bar fitted in a suitable guide bracket
and provided with a rack with which gears a worm mounted in the bracket, by
the rotation of which the bar may be moved backwards or forwards as required.
The invention will be fully described with reference to the accompanying
drawings;
Fig. 1. Plan of the appliance used as a window fastener.
Fig. 2. Side elevation of same.
Fig. 3. Longitudinal section of same.
Fig. 4. Plan showing the invention applied to a blind cord adjuster.
Fig 5. Side elevation of same,
Fig. 6. Longitudinal section of same.
Fig. 7. Plan showing the invention applied to cupboards, casements and similar
articles.
Fig. 8. Side elevation of same.
Fig. 9. Longitudinal section of same.
To the window, cupboard door or other structure we affix a guide bracket A
which acts as a guide and support for a sliding bolt or bar B, the bolt or bar B
fitting into the holes a in the end pieces a¹ of the guide bracket A
The sliding bar B is constructed of any suitable shape but is preferably
rectangular in section and is provided with a rack 6 on its face, of suitable
size and shape to engage with a worm C.
The worm C is mounted on a spindle D, fitted to the end pieces a¹ of the guide
bracket A and is free to rotate thereon in either direction. The worm C may be
rotated by passing the hand across it, and by rotating it in one direction or the
other, the sliding bolt or bar B is moved either backwards or forwards as required.
For window catches as shown in Figs. 1, 2 and 3 the guide bracket B is made
sufficiently short to allow of its being fixed to an ordinary window sash.
The hole e in the hasp or staple E does not pass completely through it, so that
the sliding bolt B abuts against the back of the hasp or staple E to hold the
window sashes apart and prevent rattling.
A fastener or catch so constructed will be very easy to operate, but from the
outside of a window or door could not be moved by the insertion of any
tool.
In this form it is preferable to make the teeth of the rack by means of notches
cut or sunk into the bar but an ordinary rack may be employed.
When used as a blind cord adjuster as shown in Figs. 4, 5 and 6 at one extremity
of the bar B is fixed a knob or pulley 6' round which the blind cord passes. The
tension of the blind cord is adjusted by moving the sliding bolt or bar B up or
down by means of the worm C.
Referring to Figs. 7, 8 and 9 a similar arrangement to the above is shown and
the same letters of reference will apply to each. The invention is here shown
applied to a fastener for cupboards, casements and similar articles. The sliding
bar B is constructed as above described with a rack and worm C and a hasp or
staple E is provided into which the sliding bolt or bar B passes and so secures the
cupboard door or casement.
?
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is:-
:-
1. A catch or fastener for securing windows comprising a sliding bolt or bar

is moved backwards and forwards and a hasp or staple, the hole in which does not
pass completely through it, so that the sliding bolt or bar abuts against the back
of the hasp or staple and so forces the sashes apart and prevents rattling, sub-
stantially as described.
2. A device for fastening blind cords and adjusting the tension thereof com-
prising a sliding bar or bolt, fitted into a suitable guide and supporting bracket
constructed with a rack on the face and a worm mounted on the bracket gearing
therewith by which the bar is moved up and down substantially as described and
shown in the accompanying drawings.
3. A catch or fastener for securing cupboards, doors, casements or the like com-
prising a sliding bolt or bar fitted into a suitable guide and supporting bracket
constructed with a rack on the face and a worm mounted on the bracket gearing
therewith by which the bar is moved backwards or forwards in or out of a hasp
or staple substantially as described and shown in the accompanying drawings.
4. A catch or fastener for windows and other structures constructed and arranged
substantially as described and shown.
