Improvements in Means for Securing Handles to Railway and other
Carriage Doors.
I, THOMAS WILLIAM WILKES, with the Firm of William Wilkes, of Mill Lane
Works, Bloxwich, near Walsall, Staffordshire, Lock Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to means for securing the handles of locks to railway and
other carriage doors.
It consists essentially in providing the door with an escutcheon having a pro-
jecting recessed boss and the spindle of the lock which is secured to the handle
and which passes through such recessed boss, with a collar, the latter being
retained within the recessed boss by means of a removable fork device.
In the case of a single-handle lock I propose to attach to the outside of the door
an escutcheon secured at the top and bottom to the framework of the door by suit-
able bolts or screws. The escutcheon is furnished near its centre with an outward
boss or projection which is recessed and the bottom of which is concave or cup-
shaped. A suitable hole or key way through the bottom of this recess allows the
spindle of the door handle to pass through to the lock of the door which it 'controls.
The other end of the spindle is secured to the door handle in any suitable way
and if desired it may be inserted therein during casting. Where the spindle enters
the stem of the handle the latter is furnished with a shoulder which is of such
diameter as to snugly fit within the recessed boss of the escutcheon. The space
between this shoulder on the handle and the bottom of the cupped recess contains
a collar which is rounded off to coincide with the cup of the recess, and also
allows a fork to be inserted through the boss and against the opposite flat side of
the collar.
The collar is formed on or securely fixed to the spindle, and, if desired, the
bearing formed by the collar fitting within the cup recess of the escutcheon boss
may be furnished with balls so as to become an ordinary ball bearing.
The boss on the escutcheon is provided at top or bottom or at one of its sides
with a transverse slot permitting the insertion of a suitable fork which will abut
against the flat side of the aforesaid collar, and the prones of the fork passing by
the sides of the spindle may enter and be secured in the opposite side of the boss
by means of screws; or the fork may be similarly secured in the entering slot
by means of a single screw at its arch and in this case the prongs of the fork
need not be continued beyond the spindle of the handle.
The handle having been placed in position, the spindle being passed through
the escutcheon, and the collar on the former bearing directly or indirectly against
the cupped bottom of the boss, the fork is inserted through the slot in the boss
and abuts against the flat side of the collar, thus keeping the handle in its position.
In the case of a double handle lock, it is necessary to attach an escutcheon as
above described to both the outside and the inside of the door and thesa
escutcheons may be bolted together through the framework of the door. The

page_text: spindle of the one handle, e.g. the outside handle, will be hollowed out to a square
or similar suitable section and the spindle of the other handle, in this case the
inside handle will be square or corresponding section and be inserted therein.
In this way the lock may be actuated by either handle for they will turn simul-
taneously, and the handles are secured in the bosses of the scutcheons in the
above described manner.
Each handle therefore is provided with an escutcheon having a recessed boss, a
spindle fitted with a fixed collar and a retaining fork.

Improvements in Means for Securing Handles to Railway and other
Carriage Doors..
I, THOMAS WILLIAM WILKES, with the Firm of William Wilkes, of Mill Lane
Works, Bloxwich, near Walsall, Staffordshire, Lock Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment:-
This invention relates to means for securing the handles of locks to railway and
other carriage doors.
It consists essentially in providing the door with an escutcheon having a pro-
jecting recessed boss and the spindle of the lock, which is secured to the handle
and which passes through such recessed boss, with a collar, the latter being
retained within the recessed boss by means for a removable fork device.
order to more particularly describe my invention, reference is had to the accom-
In

Figure 1 is a front elevation of the outside handle and escutcheon
Figure 2 is a side elevation of the same.
Figure 3 is a vertical section on line 1-2 of Figure 1.
Figure 4 is a front and side view of fork-device.
Figure 5 is a plan shewing general arrangement with both outside and inside
handles.
In the case of a single-handle lock I attach to the outside of the door an
escutcheon secured at the top and bottom to the framework of the door by suitable
bolts or screws.
The escutcheon is furnished near its centre with an outward boss or projection b
which is recessed and the bottom of which is concave or cup-shaped, as shewn on
Figure 3. A suitable hole or key-way c through the bottom of this recess allows
the spindle d of the door handle A to pass through to the lock of the door which it
controls.

The other end of the spindle is secured to the door handle in any suitable
way and preferably it is "laid in" or inserted in the handle during the casting of
the latter. Where the spindle enters the stem of the handle the latter is furnished 4
with a shoulder e which is of such diameter as to snugly fit within the recessed
boss of the escutcheon a. The space between this shoulder e on the handle and
the bottom of the cupped recess contains a collar f which is rounded off to coin-

boss b and against the opposite flat side of the collar f.
g
which will
The collar is formed on or securely fixed to the spindle and, if desired, the
bearing formed by the collar fitting within the cup recess of the escutcheon boss
may be furnished with balls so as to become a ball bearing of the ordinary type.
The boss 6 on the escutcheon a is provided at top or bottom or at one of its sides
with a transverse slot permitting the insertion of a suitable fork
abut against the flat side of the aforesaid collar, and the prongs gig of the fork
passing by the sides of the spindle may enter and be secured in the opposite
side of the boss b by means of screws; or the fork g may be similarly secured in
the entering slot by means of a single screw h at its arch and in this case the
prongs of the fork need not be continued beyond the spindle of the handle. The
handle having been placed in position, the spindle being passed through the escut-
cheon, and the collar on the former bearing directly or indirectly against the
cupped bottom of the boss, the fork is inserted through the slot in the boss and
abuts against the flat side of the collar, thus keeping the handle in its position.
In the case of a double handle, see Figure 5, is is necessary to attach an
escutcheon as above described, to both the outside and the inside of the door and
these escutcheons a a¹ may be bolted together through the framework of the door.
The spindle of the one handle e.g. the inside handle B will be hollowed out to a
square or similar suitable section and the spindle of the other handle, in this case
the outside handle A will be of square or corresponding section and be inserted
therein.
In this way the lock may be actuated by either handle for they will turn simul-
taneously, and the handles are secured in the bosses of the escutcheon in the
above described manner.
Each handle therefore is provided with an escutcheon having a recessed boss b,
a spindle fitted with a fixed collar f and a retaining fork g.
It will be observed that by laying the spindle within the shoulder and stem of
the handle during casting I am enabled to make the wearing parts of the bearing
wholly of iron (the handle being usually of brass) and, further, that in my
arrangement I do not weaken the spindle by grooving it or otherwise reducing its
diameter between its junction with the handle and stem.
The end of the spindle which is laid in the shoulder of the handle may be
enlarged and notched so as to be more firmly secured integrally with the handle
in the casting operation.
The collar is also rounded off inwardly so as to form a very effective and
easily manipulated bearing. The strain on the handle is borne wholly by the fork
device, and the check screw which serves only to secure it in its position, is in
no way subjected to this strain; it is therefore impossible to wrench the handle
out of the lock.
I have illustrated and described my invention as applied to railway carriage-door
handles; in the case of other doors the procedure is identical with, or very similar
to that described.
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). Means for securing handles to railway and other carriage doors, consisting in
securing the spindle to the door handle, a collar being formed on the spindle
having inwardly a rounded edge. entering the cup-shaped socket of a recess formed
in the boss of the door escutcheon and outwardly a flat surface, the spindle being
retained in its position, when passing through the slotted boss of an escutcheon,
by a two-pronged fork device fitting over the spindle exterior to the flat side of
the collar and said fork itself passing through the slot within and secured by a
check screw in the boss of the escutcheon, substantially as and for the purposes
described.

page_text: (2). In means for securing inside handles to railway and other carriage doors,
the combination of a spindle provided with a collar and notched head piece
embedded in said inside handle without reducing the diameter of the stem of the
spindle, with a slotted boss formed in the escutcheon of the door and with a two-
pronged fork device inserted into the said slotted boss and securing the spindle in
its position when passing through the boss of the escutcheon, substantially as
described and illustrated.
