TRUVIDIONAL DI MULTIVATION.
Improvements in and connected with Locking Rods for Holding
Card Catalogues, Indices, and the like.
A communication from abroad by HERBERT ELBRIDGE DAVIDSON, of
146 Franklin Street, Boston, United States of America, Merchant.
I, PHILIP MIDDLETON JUSTICE of 55 and 56 Chancery Lane, in the County
of Middlesex, Fellow of the Chartered Institute of Patent Agents, do hereby
declare the nature of this invention to be as follows:-
This invention relates to lock rods for card catalogues, indices, and the like, the
object of the invention being to provide a suitable fastening device for the lock
rod, thus preventing the same being withdrawn either accidentally or mischievously,
and the cards from being disarranged.
The invention comprehends a support, preferably in the form of a socket,
adapted to be secured in or to the drawer end, usually the front, and adapted to
receive the outer end of the lock rod inserted therethrough, said rod end being
received within said support and thereby removed from ready access, except by
the use of a releasing device which is hereinafter referred to as a key. The rod
end is preferably concealed by a closure filling the opening in the support
through which the rod is inserted, which closure is removable only by the use of
a key.
According to this invention a suitable support in the form of a socket may be
set into the drawer front, the same being provided with a face flange, and at its
inner end with an inturned flange interiorly threaded. The lock rod is also
threaded at its front end, and upon this threaded end of the lock rod is screwed
a knob constituting a closure for the end of the socket. The knob or closure has
a reduced portion or neck upon which is loosely mounted the fastening collar
threaded to cooperate with the threaded socket. The fastening collar loose on
the neck and therefore loose on the lock rod is held in position on the said neck
by say a lock nut threaded on the end of the lock rod. The closure is provided
with diametrically opposite longitudinal grooves diverging from the face of the
closure towards the back thereof for the reception of a suitable key which may be
bifurcated or forked at its end, the two arms being adapted for insertion in the
grooves in the closure before referred to. The fastening collar at its periphery is
provided with a groove which when in proper position registers with one or the
other of the grooves in the closure. One of the arms of the key is preferably
longer than the other arm so that when the key is inserted in the closure the long
arm of the key abuts against the face of the fastening collar; the key is then
rotated, rotating with it the closure and its connected lock rod until the closure
groove which receives the long arm of the key, registers with the groove in the
fastening collar when the key will at once slide forward and its long arm will
enter the groove in the fastening collar, enabling the latter to be turned by the
key and unscrewed from the socket to release the lock rod. The lock rod is
inserted and secured in the socket in like manner by the key which is afterwards
withdrawn.
It will be understood that the fastening collar which alone fastens the lock rod
to the socket is at all times concealed by the, closure and is accessible only through

page_text: the opening or openings in the closure by means of a suitable device provided for
that purpose. The closure with its connected lock rod may be rotated individually
without in any way affecting the fastening collar in which the closure and its lock
rod may rotate freely.

A communication from abroad by HERBERT ELBRIDGE DAVIDSON, of
146 Franklin Street, Boston, United States of America, Merchant.
I, PHILIP MIDDLETON JUSTICE of 55 and 56 Chancery Lane, in the County
of. Middlesex, Fellow of the Chartered Institute of Patent Agents, 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 relates to lock rods for card catalogues, indices and the like, the
object of the invention being to provide a suitable fastening device for the lock
rod, thus preventing the same being withdrawn either accidentally or mischievously,
and the cards from being disarranged.
The invention comprehends a support, preferably in the form of a socket,
adapted to be secured in or to the drawer end, usually the front, and adapted
to receive the outer end of the lock rod inserted therethrough, said rod end being
received within said support and thereby removed from ready access except by the
use of a releasing device which is hereinafter referred to as a key.
The rod end is preferably concealed by a closure filling the opening in the
support through which the rod is inserted, which closure is removable only by the
use of a key.
In the drawings
Fig. 1 is a sectional detail view showing my invention.
Fig. 2 a right-hand or face view of Fig. 1.
Fig. 3 top and side views respectively of the preferred form of fastening collar;
and
Fig. 4 an illustration of a convenient form of key.
Referring to the drawing in the particular construction selected to illustrate my
invention, A is a suitable support shown in the form of a socket, and as set into
the drawer front, the same being provided with a face flange a, and at its inner
end with an inturned flange a¹ interiorly threaded as shown. The lock rod B is
also shown threaded at its front end, and upon this threaded end of the lock rod is
screwed the knob b constituting a closure for the end of the socket as best shown
in Fig. 1. The knob or closure has a reduced portion or neck upon which is
loosely mounted the fastening collar c threaded to co-operate with the threaded
socket A as shown. The fastening collar loose on the neck b, and therefore loose
on the lock rod is held in position on the said neck in the present instance by a
lock nut 2 threaded on the end of the lock rod.
As herein shown the closure is provided with diametrically opposite longi-
tudinal grooves 6 diverging from the face of the closure towards the back thereof,
as shown in Fig. 1, for the reception of a suitable key as for instance shaped as
shown in Fig. 4 wherein the key K is bifurcated or forked at its end, the two
arms k, k¹, being adapted for insertion in the grooves referred to. The fastening

page_text: collar c at its periphery is provided, as herein shown, with a groove c' which when
in proper position registers with one or the other of the grooves b³.
Referring to Fig. 4, it will be seen that one of the arms as k¹ of the key K is
longer than the other arm, so that when the key is inserted in the closure 6 the
long arm of the key abuts against the face of the fastening collar; the key is
then rotated, rotating with it the closure and its connected lock rod B until the
groove 63 which receives the long arm of the key, registers with the groove c' in
the fastening collar c, when the key will at once slide forward and its long arm will
enter the groove in the fastening collar, enabling the latter to be turned by the
key and unscrewed from the socket to release the lock rod. The lock rod is
inserted and secured in the socket in like manner by the key K which is afterwards
withdrawn.
It will be seen that the fastening collar which alone fastens the lock rod to the
socket is at all times concealed by the closure b, and is accessible only through the
opening or openings in the closure by means of a suitable device provided for that
purpose. The closure with its connected lock rod may be rotated individually
without in any way affecting the fastening collar in which the closure and its lock
rod may rotate freely. The member a of the device is one form of support and is
so denominated in the claim.
The invention is not limited to the construction or arrangement of parts herein
shown, for it is evident it may be embodied in other constructions without departing
from its spirit and scope.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
from abroad by my foreign correspondent, I declare that what I claim is :-
1. The combination with a threaded support, of a lock rod, and a fastening
collar rotatably mounted and held against longitudinal movement on said rod, and
threaded to engage said threaded support, substantially as described.
2. The combination with a threaded, socket-like support, of a lock rod inserted
through an opening therein, a fastening collar rotatably mounted and held against
longitudinal movement on said rod, and threaded to engage said threaded support,
and a closure for the opening in said support to substantially conceal the said
fastening collar, substantially as described.
3. A threaded socket-like support, a lock rod, and a closure for said support
provided with a key opening, combined with a fastening collar rotatably mounted
on the said rod at the back of and held against longitudinal movement on said rod
by said closure, and threaded to engage said support, and a key adapted for
insertion within the said support, through said key opening, to engage said collar
and rotate the same, substantially as described.
4. A threaded socket-like support, a lock rod, a closure mounted upon the end
thereof, combined with threaded fastening collar rotatably mounted upon the said
closure and restrained thereby against longitudinal movement on said rod, and a
lock nut to retain the said fastening collar in its position on said closure,
substantially as described.
5. The combination with a support, of a lock rod and a fastening collar
rotatably mounted and held against longitudinal movement on said support, and
adapted to engage and lock with said support to thereby hold said rod in position,
substantially as described.
