LETTERS PATENT to Alexander Bell, of Edinburgh, in the County of Mid
Lothian, North Britain, for the Invention of IMPROVEMENTS IN FIXING
LOCK AND DOOR HANDLES."
Sealed the 26th June 1877, and dated the 7th April 1877.
PROVISIONAL SPECIFICATION left by the said Alexander Bell at the Office
of the Commissioners of Patents on the 7th April 1877.
ALEXANDER BELL, of Edinburgh, in the County of Mid Lothian, North Britain.
"IMPROVEMENTS IN FIXING LOCK AND DOOR HANDLES."
This Invention which relates to improvements in fixing lock and door handles
has for its objects to dispense with the use of screws in making the attachment,
to secure firmness and steadiness of the knobs, as well as simplicity of arrangement
and facility in fixing and removing.
Under a first modification of the said Invention one or both ends (accordingly as
desired) of the spindle is or are furnished with slots or holes extending through the
spindle, and upon the latter the knobs are adjusted to the required position, varying
with the thickness of door or lock. In the outside face of the knobs cavities are
sunk for giving access to the spindle ends when the knobs are placed thereon, and
allowing of the insertion in the slots or holes aforesaid of pins, through the hands
of which are passed loose rings, which prevent the pins from passing entirely
through the holes and secure the knobs in position on the spindles. Covers are
provided to screw into the cavities in the faces of the knobs, which are readily
unscrewed when access to the pins is required. One end only of the spindle may
be provided with slots if desired, and a series of washers or rings used to pack the
opposite end to suit the thickness of the door or lock.
Under a second modification of this Invention the neck of one or both knobs is
slotted correspondingly with the spindle and a pin inserted. Over the neck a collar
of india-rubber or other equivalent material is closely fitted, and furnished with a
similar hole or slot. After the pin is dropped into the slot or hole the said collar is
moved on the neck so as to cover the pin and prevent it from falling out, and when

page_text: it is desired to remove the knob the collar is moved back and the pin taken out.
By this arrangement the disadvantages attending the use of a fixed combined rose
and collar are obviated.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Alexander Bell in the Great Seal Patent Office on the 2nd October
1877.

"IMPROVEMENTS IN FIXING LOCK AND DOOR HANDLES."
My said Invention which relates to improvements in fixing lock and door handles
has for its objects to dispense with the use of screws in making the attachment, to
secure firmness and steadiness of the knob, as well as simplicity of arrangement,
and facility in fixing and removing.
Under a first arrangement of my said Invention one or both ends, accordingly as
desired, of the spindle is or are furnished with slots or holes extending through the
spindle, and upon the latter the knobs are adjusted to the required position, varying
with the thickness of the door or lock. In the outside face of the knobs cavities
are sunk for giving access to the spindle ends when the knobs are placed thereon,
and allowing of the insertion in the slots or holes aforesaid of pins, through the
heads of which are passed loose rings, which prevent the pins from passing entirely
through the holes, and secure the knobs in position on the spindles. Covers are
provided to screw into the cavities in the faces of the knobs, which are readily
unscrewed when access to the pins is required. One end only of the spindle may
be provided with slots, if desired, and a series of washers or rings used to pack the
opposite end to suit the thickness of the door or lock.
Under a second arrangement of my said Invention the neck of one or both knobs
is slotted correspondingly with the spindle, and a pin inserted. Over the neck a
collar of india-rubber, or other equivalent inaterial is closely fitted, and furnished
with a similar hole or slot. After the pin is dropped into the slot or hole the said
collar is moved on the neck so as to cover the pin and prevent it from falling out,
and when it is desired to remove the knob the collar is moved back and the pin
taken out.
And in order that iny said Invention may be properly understood I now proceed
more particularly to set forth the system, mode, or manner in or under which the
same is or may be used or practically carried into effect, reference being had to the
annexed Sheet of Drawings and to the letters and figures marked thereon, that is
to say,-
· Figures 1 and 2 represent respectively a sectional plan and a side view of one
arrangement of iny improvements in fixing the handles of locks or doors; the
knobs A, A', are pierced or slotted longitudinally, and are also furnished with
cavities a, a', into which the covers b, b, are screwed, as shown. The spindle D,
which is square in section, is passed through the knob A as far as is permitted
by the washers, bearing against the shoulder of the cavity a on the one side,
and secured on the spindle D by the split pin c passing therethrough, as shown.
The said spindle is then inserted in the hole provided for its reception in the lock,
and passed thence through the handle or knob A¹ projecting beyond the metal
plate e secured to the inner end of the cavity a¹ of the knob A¹. The end of the
spindle D which passes through the knob A¹ is furnished with a shoulder or check,
and the lower part thereof is slotted, as seen more particularly at Figure 3, which
represents on an enlarged scale a side view of the spindle D with the knobs or
handles removed. Into the said slot is passed a pin f, in the head of which is
inserted a ring g, which after the insertion of the pin fassumes the position seen at
Figures 1 and 2, and thereby firmly secures the spindle D in its proper place, the
washers & regulating the degree of tightness of the attachment. The knobs or

page_text: roses"
handles A, A¹, are thus secured to the door B firmly and steadily. The "
are attached to the door in the usual manner. When the attachment has been
made, the covers b, b¹, are screwed to the knobs or handles A, A¹, and the pins f
and c are hidden, and are maintained in their respective alots or holes.
Figures 4, 5, and 6 illustrate another arrangement of my said Invention in which
the necks of the knobs are pierced on both sides correspondingly with the spindle
on which they are secured; Figure 4 is a side elevation of this arrangement;
Figure 5 is a plan, and Figure 6 is a transverse section of the neck of the knob or
handle drawn to an enlarged scale. Upon the necks of the knobs K, K¹, are slipped
spring collars m, m³, preferably made of steel, and which firmly grasp the necks of
the knobs. The said collars m, m³, are split or divided in such a manner that they
do not embrace the entire necks of the knobs, as more particularly seen at Figure 6.
At Figure 4 the collar m is shown in such a position that the slot in the neck of
the knob K corresponding to that in the spindle M is laid bare for the insertion of
the pin n, which is shown inserted. For the purpose of adjustment to the thick-
ness of the door or lock the spindle may be provided with several holes. On the
knob K the collar m¹ is shown passed around the neck after the insertion of the
pin n', as also seen at Figure 6, whereby the pins are prevented from leaving
the slots, and the handles or knobs secured firinly on the spindle, the pins passing
both through it and the necks of the knobs. The strain on the pins being borne on
both sides of the knob instead of on one side only as hitherto, when it is desired to
remove the knobs or handles the collars are moved to the position shown with
regard to the collar m in Figure 4, and the pins can easily be removed.
By the foregoing arrangements the knobs or handles can readily be fixed to or
removed from locks or doors, and a simple, firm, and steady fixture is obtained
without the use of screws.
Having now described and particularly ascertained the nature of my said
Invention, and the system, mode, and manner in or under which the same is or
inay be used or practically carried into effect, I would observe in conclusion that
what I consider to be novel and original, and therefore claim as the Invention
secured to me by the herein-before in part recited Letters Patent is,―--
First. Securing the knobs or handles of doors and locks by means of a spindle
slotted at one or both ends, and having pins or their equivalents inserted and
secured, whereby a firm and steady attachment is made without the use of screws,
substantially as herein-before described and shown on the accompanying Sheet of
Drawings.
Second. Securing the knobs or handles of doors and locks by means of pins
passing through slots formed in the necks of the knobs or handles, and in the
spindle, which pins are maintained in position by divided collars grasping the necks
of the knobs or handles, the divisions in which collars allow of the insertion or
removal of the said pins, whereby a simple, firm, and steady attachment is
obtained without the use either of screws or of a combined "rose" and collar,
substantially as herein-before described and shown on the accompanying Sheet of
Drawings.
In witness whereof, I, the said Alexander Bell, have hereunto set my hand
and seal, this Twenty-first day of September, One thousand eight hundred
