Improvements in Fastenings or Looks for Windows, Doors, Show
Cases, and the like.
RICHARD TRAINOR 33 Egerton Street Prestwich near Manchestor Teacher of
Manual Instruction in Wool Practical Joinery Drawing and the like do hereby
declare the nature of this invention and in what nanuer the same is to bo
performed, to be particularly described and ascertained in and by the following
statement:—
This invention relates to fastenings for doors, show cases, swivel and sliding
sashes with and without divided styles and the like, which when in operation
the catch grips and bolts the companion style in sashes, or the jamb in show cases
or door frames.
In the drawings the same reference letters indicate the same parts in all the
drawings.
Figure 1 is a horizontal section through V W in Figure 2 of the fastening in a
sliding sash with divided styles.
Figure 2 is a vertical section through X Y in Figure 1 of the fastening in a
sliding sash with divided styles.
Figure 3 is a vertical section through T U in Figure 2 of the fastening in
a sliding sash with divided styles with a portion of the lock plate.
Figure 4 is an elevation of the companion or hanging style, with the striking
plate in position in a sliding sash with divided styles.
A is the sash style.
B is the companion or hanging style.
Cis the window pane.
Dis the sash cord.
E is the box or frame of the fastener.
Fis the lid in the fraine.
G is a spring.
His the catch or bolt.
J is the striking plate.
Kis the escutcheon or key hole.
Lis nu opening in the catch or bolt.
M is a projection in the catch or bolt.
N is a slot in the striking plate J.
E and F have holes which are concentric with the tapered opening L in the
catch H.
H has its two ends turned to fit in the holes in E and F.
The opening L in the catch H may be square and taper.as in these drawings or
round and taper or any other shape that the user may desire.
A carriage door key may be inserted at L and the catch H turned from its
position when fast (as seen in its section in Figure 2) until it is upright as seen in
the same figure indicated by dotted lines.
On the catch H is a projection M which comes in contact with the spring G.
When the catch H is down, the spring works against the projection M and
assists to keep the catch down and tends to increase the grip on the striking
plate J.
When the catch H is up as seen in the broken lines in Fig. 2 the spring acts
against the projection M and prevents its falling down.

page_text: In Fig. 3 the rim of the catch H is drawn taper towards its hub or boss.
In Fig. 1 the tapered rim surfaces of the catch H are in contact with the
tapered surfaces on J.
The tapered surfaces on J incline to each other lengthways as shown by the
dotted lines 1. 1. in Fig. 4, or the slot N may be made parallel lengthways
instead.
The tapered surfaces on the catch H and striking plate J are not concentric
with the centre of the opening L but are formed in shape as a wedge or inclined
plane so that when the catch H comes down as seen in Figures 1 and 2 the striking
plate J is gripped by the catch H and the lower down it goes and the tighter is
the grip on the striking plate.
It follows from this that anything fastened to the striking plate J will be pulled
towards the sash style A and gripped accordingly.
The catch H may be made with tapered rim surfaces as seen by the thickened
curved line in Fig. 2 (whilst in an upright position) instead of as herein described
in the section in Fig. 2.
K is an escutcheon or keyholo.
Au axle or centre pin may be fitted in the hollow L of the cutch H and the
other end may be shaped so as to fit either a hollow or solid key, such axle
or pin is not intended to project beyond the surface of the sash style A and
escutcheon K.
As seen in the Figures 1 and 2 the sash style A and companion or cord style B
are locked and gripped together.
By inserting the key in the hole L and turning the catch H until it is in a
vertical position (as represented by the dotted lines in Fig. 2), the styles A and B
are released and as all the working parts of the fastener are flush or sunk below
the surfaces of A and B, then the style A may swivel aud the like away from B
without fear of any obstruction from the said fastener.
I do not limit myself to the details of construction shewn as changes muy ensily
be made therein and still the essential features of my invention be employed.
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
1. The mode of gripping the striking plate by a tilting catch bar H which has
a flange or flanges with an inclined surface or surfaces to correspond with a wedge
shaped inclined plane with the inclined surface or surfaces inside the slotted portion N
of the striking plate J. as described and shewn in the accompanying sheet of
drawings.
