COSIT LELE SPECIFICATION,
Improvements in Indicator Fastenings for Private Apartments.
I, JOSEPH KAYE, of the firm of Joseph Kaye and Sons, Limited, of South Accom-
modation Road, Leeds, in the County of York, Lock Manufacturers, 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 has for its object the combination of a simple mode of fastening a
door from within and indicating without that the apartment is "engaged," such
arrangement being effected without the intervention of levers or other intermediate
operating mechanism, thus reducing the working parts and enabling the combined
fastener to be made at less cost with the same efficiency, than hitherto.
I accomplish my object by constructing a horizontal sliding bolt which acts as the
fastener. The bolt is mounted within suitable guides on to a plate for securing the
same to the inside of the door of the apartment to this bolt is secured a pin passing
through a slot in the plate, the length of the pin is regulated by the thickness of the
door through which also a slot is cut for the horizontal traverse of the pin when
moved in one direction or the other; a plate is also secured to the outside of the door
with a corresponding slot and forms the bottom of the casing in which the indicator is
operated.
The indicator is composed of any suitable material with the word "engaged" on
each side of the same, and is formed below with an inclined plane; the pin attached
to the sliding bolt operates upon the inclined plane, raising the indicator when the
door is bolted into such position that, the word "engaged" appears in a prepared
aperture in the casing: when the bolt is withdrawn, the indicator drops and the word
"engaged" retires into the casing below the aperture by its own weight.
The object of having the word "engaged" on each side of the indicator is, that the
same when so made will do for either hand of a door, for on turning the same from
one side to the other, the inclined plane is reversed so that it is raised by the pin on
sliding the bolt or fastener for securing the door.
In the accompanying drawings,
Fig. 1 represents an elevation of the sliding bolt of my apparatus secured to a door
and engaging with a staple on the door frame.
Fig. 2 is a sectional plan of a portion of a door and frame with my improvement
attached thereto.
Fig. 3 is a front view of the indicator casement.
Fig. 4 a view of the indicator, and
Fig. 5 a view of the sliding bolt and pin for operating the indicator.
The plate A. is secured to the inside of a door of an apartment opening to the
"right" or "left hand ;" and mounted in guide staples B. attached to the plate is a
horizontal bolt C. for securing the door when the former is slid to engage with the
staple E. To this horizontal bolt C. is rigidly secured a pin F. of such length as to
pass through a slot hole R. formed through the plate A. and door D. and be in
contact with the indicator plate H. placed within the casing J. secured to the outside
of the door.
The indicator plate H. may be of any kind of material, with the word "engaged"
on either side, and is formed with an inclined plane P. and parallel guiding piece
at K. This plate H. is placed in the casing J. with the inclined plane P. towards the
closing edge of the door, the inclined plane resting upon the operating pin F. secured
to or forming part of the horizontal sliding bolt C. so that on closing the door and
moving the horizontal sliding bolt towards the closing edge, the door is bolted, and by
the pin F. operating on the inclined plane P. of the indicator plate H. raises the same such
a distance that, the word "engaged" appears_opposite an aperture in the casing; and
when the bolt is withdrawn from the staple E. the pin F. moves towards the parallel
Prine 621

page_text: guiding piece K. thus allowing the indicator plate to drop by its own weight and the
word "engaged" to retire below the aperture.
By constructing the several parts in the manner described, the apparatus may be
fitted to a door opening to "the right or left hand," and the occupation of the
apartment indicated, by placing the indicator plate H. in the casing J. with the
inclined plane side of the plate towards the opening edge of the door, the plate
being operated without the intervention of levers or other intermediate operating
mechanism.
Having now particularly described and ascertained the nature of this inven
tion, and in what manner the same may be performed, I declare that what I
claim is―
The combination of a sliding bolt C. having a pin F. attached thereto operating on the
inclined plane of indicator plate H. mounted in a casing J. all arranged substantially
in the manner and for the purpose as hereinbefore described.
