TJUDSON R. 1VELLOTT, OF TULIA, TEXAS.
DOOR-FASTENER.
.9(',948. Specification of Letters Patent. Patented Aug. 23, 1910.
Application filed December 28, 1909. Serial No. 535,317.To all whom it may concern:
Be it known that I, JUDSoN R. MELLOTT,
citizen of the United States, residing at
Tulia, in the county of Swisher and State of
5 Texas, have invented certain new and useful
Improvements in Door-Fasteners, of which
the following is a specification.
This invention relates to door fasteners
and refers particularly to a. device of this
jo nature which may be conveniently attached
to any form of door or hinged closure.
An object of this invention is to provide
a portable fastener which may be conven-
iently carried by persons traveling and who
15 desire to lock the doors of their rooms in
hotels.
The invention has for another object the
provision of a fastener of this character
which comprises but few parts and which
20 does not necessitate the rigid application of
any one of the parts to either the door or
the jamb surrounding the same, but has the
parts thereof so formed that they can be de-
tachably secured in position and firmly se-
25 cure the door when closed.
This invention also contemplates the pro-
vision of a reinforcing plate for engagement
with the jamb of the door when the device is
to be employed permanently, and to which
30 the securing member is engaged.
For a full understanding of the inven-
tion reference is to be had to the following
description and accompanying drawing, in
which:-
35 Figure 1 is a perspective view of a section
of a door and the jamb thereabout showing
the application of the improved fastener.
Fig. 2 is a horizontal section through the
door and jamb having the fastener applied
40 thereto and in a locked position. Fig. 3
discloses the application of the fastener to
the door and jamb without the use of the se-
curing plate. Fig. 4 is a detail perspective
view of the retaining member, and Fig. 5 isI
45 a perspective view of the retaining plate.
Corresponding and like parts are referred
to in the following description and indicated
in all the views of the accompanying draw-
ing by the same reference characters.
50 Referring to the drawing the retaining
member, which is disclosed to advantage in
Fig. 4 comprises a length of wire which is
bent upon itself and twisted toward its outer
end to form an eye 10 and a pair of arms 11.
65 The arms 11 are flattened at their innerfaces which engage against the jamb 12 of
the door-frame and are curved inwardly at
their ,free ends to form hooks 13. The hooks
13 are flattened and reduced toward their
outer ends to form biting edges whereby the 60
same may be easily engaged within the face
of the jamb 12.
A securing plate 14 is employed which
comprises a flattened portion of metal of
rectangular formation which is secured by 65
suitable screws 15 to the inner face of the
door jamb 12 and is provided centrally with
a pair of openings 16 for the reception of
the hooks 13. When the plate 14 is em-
ployed the door jamb 12 is cut-away at its 70
inner face to form a recess or pocket 17 for
the reception of the hooks 13 so as not to
damage the jamb 12. The provision of the
plate 14 and the pocket 17 enables the se-
curing of the hooks 13 readily through the 75
plate 14 and thus forms a means whereby
the jamb is especially adapted for the recep-
tion of the fastener.
It will be noted from the drawing that
the eye 10 and the crotch of the retaining 80
member extend beyond the inner face of the
jamb 12 and consequently beyond the inner
face of the door 18 when closed, the crotch
receiving therethrough a locking pin 19
which is engaged against the inner face of 85
the jamb 12 and door 18.
The locking pin 19 comprises a length of
wire which is looped at one end as at 20 to
form a suitable finger-hold for. withdrawing
and inserting the locking pin 19 through the 9C
crotch, while its opposite end is preferably
pointed as at 21 to admit of the easy posi-
tioning of the locking pin 19.
In Fig. 3 is disposed the application of the
retaining member wherein the hooks 13 of 95
the same are forced into the body of the
jamb 12 and thus prevent the longitudinal
movement of the retaining member in-
wardly from the jamb. The hooks 13 are
held in position and against displacement by 1 00
the closing of the door 18, the outer edge of
which abuts against the outer faces of the
arms 11 and binds the same against the in-
ner face of the jamb 12.
It is readily seen that the retaining mem-
ber and the locking pin may be conveniently
carried in the pocket and when it is desired
to fasten a door that the retaining member
may be first positioned against the inner
face of the jamb to extend the crotch and 1
