COMPLETE SPECIFICATION.
New or Improved Fastening Device, applloable for Use on Wardrobes
or the like.
1, ARTHUR EDWARD DUCKETT of 179 Portland Street, Southport in the
County of Lancaster, Machinist 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:-
The main object of this invention is to provide a new or improved fastening.
device which shall be specially applicable for use upon such articles of furniture
as are provided with one or more pairs of hinged doors. In securing such doors
in their closed position one door is usually fastened with one or more bolts or other
catches which can only be manipulated whilst the second door is open. Said second
door is then closed and locked.
My invention mainly relates to the device for fastening the first door.
In the drawings,
Figure 1 is an elevation of my device as attached to the door of a wardrobe
and as viewed from inside, the coverplates being removed.
Figure 2 is a view of a portion of Fig. 1 (parts being removed for clearness)
and shown in its unfastened position.
Figure 3 is a section of the bottom striking plate and its adjoining parts.
Figure 4 is a plan of said plate.
I provide a pair of longitudinally movable bolts A A' which are arranged in a
groove B formed in the stile C of the door. Their outer ends (which engage
with striking plates D when the door is closed) are bevilled as shown to allow the
door to be slammed to. At a convenient height to be reached by the hand and
preferably about mid way the height of the door is formed a recess E in which is screwed
or otherwise fastened a small bed plate F having pivotted to it a thumb lever G whose

links I H' whose other ends are pivotted to bolts A A', as shown, by means of
set screws or their equivalent. Each bolt A A' is in two pieces and the hiatus
between the adjacent ends is covered by tubes I having set screwe i and by
this means the length of bolts A A' is made adjustable to obtain accuracy of
fitting. A spiral spring J bearing against adjusting tube I tends to normally keep
the parts in position shown in Fig. 1. The other end of spring J bears against a
block K rigidly attached to plate F and this block forms a bearing for the inner
end of bolt A. A similar block K¹ serves a like purpose for bolt A. The outer
ends of bolts A A' slide in plates such as L, Fig. 1.
Referring to Figs. 3 & 4, the striking plate D has hole M to receive the outer
ends of bolts A A¹ & this hole instead of being circular as usual 1 make of oval
or clongated shape and thus facilitate the entrance of bolts A A' and allow a slight
degree of play.
provide cover plates if necessary and these rest in the narrow rebate shown
round groove B & recess E. They may be fastened in place by wood screws but I
prefer also to use screws in holes in the various metal parts of the device.
When turned out on a manufacturing scale the outer portion of bolts A A¹ will
be sufficiently long to fit any ordinary door of the kind for which the device is
intended and they may be cut at their inner ends if necessary, the tubes I I
allowing for adjustment.

page_text: Supposing the door to be closed (as in Figs. 1 & 3) it will be readily seen that by
depressing thumb piece G¹ the lever G is canted & the ends of bolts A A¹ thereby
withdrawn (see arrows Fig. 2) from the striking plates and thus free the door to
be opened on its hinges. The door may if desired be closed by slamming, as the
bevilled ends of bolts A A' will retract when they hit the striking plates.
The thumb piece may if desired be placed in a recess in the edge of the door &
thus be hidden from view.
This device in practico is found much more convenient to use than the ordinary
bolts and finger plates.
I do not limit myself to the precise details herein shown & described. If
desired the groove may be made in the edge of the door or if cheapness of applica-
tion be a desideratum the device may be applied to the inner surface of the door &
not auuk in & covered as described.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed, I declare that what 1
claim is
1. A fastening device having a pair of longitudinally sliding bolts which may be
simultaneously actuated by means of a lover G or its equivalent & provided with a
spring to return same to normal position substantially as & for the purposes
described.
2. In a fastening device for use on wardrobes or the like, the combination of
bolts A A¹ thumb lever G G¹ links H H' & spring J substantially as described.
3. The fastening device applicable for use on wardrobes or the like, taken as
a whole, substantially as & for the purposes specified.
Dated this 1st day of March 1895.
