Improvements in Fastenings for Door Handles.
I, ROBERT EDWARD PHILLIPS, of 70, Chancery Lane, London, W.C., in the
County of Middlesex, Chartered Patent Agent, do hereby declare the nature of this
invention which has been communicated to me from abroad by John William
McDougall, of Napier, New Zealand, and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
This invention relates to means for securing door handles upon their spindles
and its object is to provide devices which will not be displaced by ordinary wear
and tear and will hold the handles securely, and so that they may be readily
removed from or adjusted upon the door when required.
I fix one of the handles permanently upon one end of the ordinary square
spindle, and form a screw thread upon the other end of the spindle to fit the socket
of the other handle. A clutch having a square hole to fit the spindle also fits into
an escutcheon fixed to the door, and may be pressed into the escutcheon against
the resistance of a spring. The end of the handle socket is made to fit into the
clutch so that they may engage together.
f
.
In placing the handles in position on a door the spindle with its fixed handle is
passed through the lock and the clutch placed upon the other end of the spindle
and pressed into the escutcheon.
The other handle is then screwed upon the spindle until it is almost touching
the escutcheon; the clutch is then released to engage with the handle, which
may now be used to turn the spindle and operate the lock or catch..
The drawings illustrate the form which I prefer my invention should take.
Figure 1 is a section of a door handle fitted with my improvements....
Figure 2 is a modification of the same.
Figure 3 is another modification of the same.
Figure 4 is a further modification of the same.
Figure

Figure 6 is a view of the clutch in perspective.
Figure 7 shows the end of the handle in perspective.
Figure 8 illustrates a spring and pin.
Figure.9 is a section on line A-A Fig. 3.
Figure 10 represents a modification of the clutch in perspective.
**.**
Similar figures of reference indicate corresponding parts where they occur in
the different views.
(1) is the ordinary spindle made square in section and fitted on the end not
shewn on the drawing with one of the handles, to which it is secured permanently
by brazing or by a rivet, (2) is the other handle in the socket (3) of which a
screw-thread is formed, (4) is the clutch provided with a square hole (5) to fit the
spindle (1), (6) are lugs on the clutch made to fit in recesses (7) formed in the
socket (3), (8) is a spring in compression acting upon the clutch (4), (9) is the
escutcheon having a socket (10) and notches (11) as shewn by Figure 5 in the end

page_text: On Fig. 2, the spring (14) is band shape and reposes outside the socket (3) in
a groove (12) and carries a pointed pin (13). Upon pressing the clutch into the
escutcheon the pin (13) will rise and vice versa, under the operation of the
spring (14).
On Fig. 3, a similar band shaped spring (15) is used and a pin (16) with a
bevelled face. In this case recesses (17) are made in the socket (3) to receive the
pin (16) which is raised when the socket (3) enters the clutch (4). The recesses (17)
are arranged in a plane vertical to the axis of the clutch, and are longer than the
pin is thick from front to back in such proportion as is required by the forward
movement of the socket when being screwed up.
Figs. 4 & 10 shew the clutch in which the lugs (18) do not project beyond the
diameter of the clutch. In this case it is not necessary to have more than one
slot (11) in the socket (10) of the escutcheon, and the clutch is pressed back by
.inserting any suitably sharpened instrument through the said slot and between one
of the lugs (18) and the socket of the handle, the bevel (19) formed on the lug (18),
which is usually opposite the slot (11), affording ready admission for such instru-
ment, or in place of the bevel a hole to receive the sharpened instrument may
be bored in the clutch.
To fix the handles, the spindle with one handle fixed to it is passed through the
door, the escutcheon secured to the door, and the spring and clutch placed on the
spindle. The clutch is pressed back into the escutcheon and the handle screwed
on the spindle until its socket touches the escutcheon, or nearly so. The clutch
is then released to engage with the handle, which may then be used in the
ordinary way for unfastening and opening the door.
I prefer to use four lugs or a square projection on the clutch as the handle can
then be adjusted with considerable accuracy, since the handle and clutch may be
engaged together at every fourth part of a revolution of the handle.
In the form shewn by Figure 3 it is merely necessary to screw on the
handle (2) for when its socket (3) reaches the pin (16) the latter will be raised and
afterwards fall into one of the recesses (17).
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. In combination with a door spindle of square section, screw threaded at one
end and having a handle fixed on its other end, of a handle screwed upon the
spindle, a spring actuated clutch provided with lugs and an escutcheon having
recesses registering with the said lugs substantially as set forth herein.
2. In combination with a door spindle of square section, screw threaded at one
end, and having a handle fixed on its other end, of a handle screwed upon the
spindle and provided with a recess or recesses in the end of its socket, a spring
actuated clutch provided with a lug or lugs to engage with the recess or recesses
in the socket, and an escutcheon having a recess or recesses registering with the
said lug or lugs, substantially as set forth herein.
3. In combination with a door spindle of square section, screw threaded at one
end and having a handle fix on its other end, of a handle screwed upon the spindle
and provided with recesses in its socket, a spring actuated pin to engage with
the recesses in the socket, and an escutcheon substantially as set forth, herein.
4. The improved fastenings for door handles, constructed, arranged and operat-
ing substantially as set forth herein.
