Improvements in Door and Gate Fastenings,
GEORGE BALDRY, Mill House, Ditchingham, Norfolk, Carpenter, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to that class of door and gate fastening which embodies
a sliding bolt, operating in keepers; with an object to provide a simple and
improved fastening device of such a character, as will be adapted, for the con-
vience of applicaton, and with sufficent power to force the door or gate up close
to its frame.
This invention is fully described in the following specifications of which the
accompanying drawings forms a part in which are set forth, the separate parts
of my improvements which are shown, by the same letters of reference in each of
the views of which
Fig. 1, is a side elevation of my improved device showing it locked.
Fig. 2, is a side elevation of my improved device showing it unlocked.
Fig. 3 is a top plan view in the drawings forming a part of this specification.
Fig. 4 showing principal keeper D wherein toothed lever or ratchet gear fis
carried with a pin or screw b.
Fig. 5 showing fork or opening on back end of bolt, into which neck on toothed
lever or ratchet gear f is forced when bolt is locked.

page_text: C shows my improved bolt which may be of either square or round contour and
manufactured from either malleable iron, cast iron, wrought iron, brass, or any kind
of mettalic substance suitable for the purpose, and is provided with a longitudinal
arranged series of teeth i on the front side of bolt is adapted to slide in
keepers D & D keepers being attached to plate E the keepers to be in form
corresponding to the bolt and are arranged upon the plate E as shown on the
drawings.
Within the principal keeper D) is provided a toothed lever or ratchet gear f
cogging with the teeth or ratchet gear & upon the bolt, and is carried within the
principal keeper with a pin or screw adapted to engage the said bolt and keepers
within which the bolt slides, the bolt being provided with a beveled or tapered
end shown at H and engages a corresponding opening in the capstaple L which is
secured to the door or gate frame by which construction and arrangement when the
bolt is forced into the capstaple L by the operation of the toothed lever or ratchet
gear the door or gate will be forced close into or against its frame.
The aforesaid toothed lever or ratchet gear f is provided with slots or grooves a
on either sides thus forming a neck and so arranged that it comes within the fork
or opening on the back end of the front side of bolt K thus secureing bolt when
door or gate is locked, which by the operation of toothed lever or ratchet gear the
bolt is caused to slide longitudinal in the keepers to lock or unlock the door or gate.
The stump as is shown at N on plate E and hole in bolt M in back side of bolt
come in contact with one another, thus providing a means of keeping the bolt
and toothed lever or ratchet gear in position when the door or gate is unlocked.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1st. An improved door or gate fastening comprising a sliding bolt provided
with a longitudinal arranged series of teeth upon the front, with a toothed lever
or ratchet gear carried upon the principal keeper and adapted to engage said bolt
and keepers within which the bolt slides.
2nd. An improved door or gate fastening comprising a bolt with a longitudinal
arranged series of teeth on front side with a toothed lever or ratchet gear adapted
to engage the said keepers within which the bolt slides the bolt being provided
with a beveled or tapered end adapted to bear with relation to its keeper or staple
substantially as and for the purpose set forth.
3rd. An improved door or gate fastening device comprising a sliding bolt
operating in keepers the keepers corresponding to bolt toothed lever or ratchet
gear and capstaple for the purpose set forth.
