Year: 1875

page_text: LETTERS PATENT to Phinehas Edward Ayton, of Birmingham, in the
County of Warwick, Accountant Clerk, for the Invention of “Ix-
PROVEMENTS IN ATTACHING DOOR AND OTHER KHOBS TO SPINDLES."
:
PROVISIONAL SPECIFICATION left by the said Phinehas Edward Ayton
at the Office of the Commissioners of Patents, with his Petition,
on the 9th January 1875.
I, PRINDHAS EDWARD AYTON, of Birmingham, in the County of
Warwick, Accountant Olerk, do hereby declaro the nature of the said
Invention for "IMPROVEMENTS IN ATTACHING DOOR AND OTHER KNOBS TO
SPINDLES," to be as follows:-
My Invention consists of the combination or arrangement of parts
herein-after described for attaching door and other knobs to spindles
O whereby the adjustment of the moveable knob to the thickness of the
door or other articles is effected with great facility.
I employ a square spindle screwed on its angles as usual. I make the
mount of the knob hollow or of a box form, and in the said hollow

page_text: mount a screw box is enclosed, and works the thread of the said screw
box, being of a size proper to take upon the screwed end of the
spindle.
Part of the exterior of the screw box constitutos a bush or cylindrical
bearing, which works in a collar in the hollow mount of the knob. The
other portion of the periphery of the scrow box is formed into a toothed
wheel.
In the edge of the hollow mount of the knob is a slot in which a
tooth or click is jointed. When this tooth or click is in its closed
position it engages between the teeth of the toothed edge of the screw
box and locks or prevents the rotation of the screw box. By lifting the
tooth or click the screw box is at liberty to move, and by means of a
pointed instrument inserted through the slot in which the click works
the screw box may be turned and made to advance in one or other
direction on the spindle, carrying with it the moveable knob. When the 1
knob has been adjusted on the spindle the shutting down of the tooth
or click causes the latter to engage with the toothed periphery of the
screw box and fix the knob securely in its adjusted position.
In metal knobs the screw box with the toothed wheel described is
enclosed in the shoulder of the knob, which is made hollow for receiving
the said scrow box.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Phinehas Edward Ayton in the Great Seal Patent
Office on the 21st June 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PHINEHAS 2
EDWARD AYTON, of Birmingham, in the County of Warwick, Accountant
Clerk, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of January, in the
year of our Lord One thousand eight hundred and seventy-five, in the 3
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Phinchas Edward Ayton, Her
special license that I, the said Phinehas Edward Ayton, my executors,

page_text: administrators, and assigns, or such others as I, the said Phinehas Edward
Ayton, my executors, administrators, and assigns, should at any time
agreo with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN ATTACHING DOOR AND OTHER KNOBS TO
SPINDLES," upon the condition (amongst others) that I, the said Phinehas
Edward Ayton, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Phinehas Edward Ayton, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :—
My Invention consists of the combination or arrangement of parts
herein-after described for attaching door and other knobs to spindles
whereby the adjustment of the moveable knob to the thickness of the
door or other article is effected with great facility.
I employ a square spindle screwed on its angles as usual. I make the
mount of the knob hollow or of a box form, and in the said hollow
mount a screw box is enclosed and works the thread of the said screw
box, being of a size proper to take upon the screwed end of the spindle.
Part of the exterior of the screw box constitutes a bush or bearing,
which works in a collar in the hollow mount of the knob. The other
portion of the periphery of the screw box is formed into a toothed
wheel.
In the edge of the hollow mount of the knob is a slot, in which a
tooth or click is jointed. When this tooth or click is in its closed
position it engages between the teeth of the toothed edge of the screw
box and locks or prevents the rotation of the said screw box. By lifting
the tooth or click the screw box is at liberty to move, and by means of a
pointed instrument inserted through the slot in which the click works

page_text: the screw box may be turned and made to advance in one or other direction
on the spindle, carrying with it the moveable knob. When the knob lias
been adjusted on the spindle the shutting down of the tooth or click
causes the latter to engage with the toothed periphery of the screw box
and fix the knob securely in its adjusted position.
In metal knobs the screw box with the toothed wheel described is
enclosed in the shoulder of the knob, which is made hollow for receiving
the said screw box.

Having explained the nature of my Invention I will proceed to describe
with reference to the accompanying Drawing the manner in which the 1
samo is to be performed.
Figure 1 represents partly in longitudinal section and partly in elevation
a pair of china or non-metallic door knobs and their spindle, the moveable
knob of which is attached to the spindle according to my Invention;
Figure 2 is a plan of the moveable knob and spindle; Figures 3. and 4 1
are cross sections of the moveable knob; and Figures 5, 6, and 7 repre-
sent parts of my Invention as herein-after explained.
In Figures 1 and 4 the screw box is represented released, and the
moveable knob ready for adjustment on its spindle, and in Figure 3 the
screw box is represented locked and the moveable knob fixed on its 20
spindle.
The same letters of reference indicate the same parts in the several
Figures of the Drawing.
a is the moveable knob and 6 is the fixed knob; a³ is the rose of the
moveable knob and is the rose of the fixed knob; c is the spindle 2
screwed on its angles; and d is the hollow or box form metallic mount of
the moveable knob (shown separately in Figuro 5), in which hollow or box
mount the screw box e is enclosed and works. The thread of the screw
box e is of a size proper to take upon the screwed end of the spindle c,
the screwed end of the spindle after passing through the screw box 30
entering a square socket & at the back of the hollow or box mount d.
The screw box e is represented separately in section in Figure 6. The
front of the screw box e constitutes a bush or slightly conical bearing e³,
which works in the collar f. The front of the box or hollow mount dis
closed by the collar and tho screw box e retained in the said box or 35
hollow mount. The collarf (shown separately in Figure 7) is fixed in

page_text: :
its place at the front of the mount d after the screw box e has been put
in the said mount by turning or burnishing the edge of the mount dover
the edge of the collar f; as illustrated in Figure 1. The periphery of the
screw box c at the back of the bush or bearing is made into a toothed
e
› wheel o̟, the teeth of which have the form best seen in Figures, 3 and 4.
In a sloth in the edge of the hollow mount & of the moveable knob a a
tooth or click is jointed at, the said tooth or click having the shape
best seen in Figures 3 and 4. When the tooth or click i is shut down or
is in its closed position as represented in Figures 2, 3, and 5, the part **
engages between two of the teeth of the wheel g of the screw box e and
locks the said screw box, as represented in Figure 8, and thereby prevents
its rotation. When the tooth or click i is lifted, as illustrated in Figures 1
and 4, the screw box e is liberated, and may be rotated in one or other
direction by a bradawl or other pointed instrument inserted through the
5 slot 7 in the mount and made to act upon the toothed wheel g. In
adjusting and fixing the moveable knob a of a pair of knobs according
to my Invention the spindle c carrying the fixed knob 6 is passed through
the door. The tooth or click i being lifted or turned on its joint into its
open position so as to unlock the screw box e, as in Figure 1, the screwed
O end of the spindle c is passed into the said screw box e and the latter is
turned by a bradawl passed through the sloth and made to act upon the
toothed wheel g. By the rotation of the screw box within the hollow
or box mount d the moveable knob a advances gradually on the spindle c,
and the knob is adjusted to the thickness of the door. The adjustment
3. of the knob having been thus effected the tooth or click is shut down so
as to cause the part ³ to engage between two of the teeth of the wheel 9 of
the screw box e, as illustrated in Figure 3. The screw box is thus locked
and the moveable knob a fixed in its adjusted position. The removal of
the knob from the spindle is effected by lifting the tooth or click i and
O rotating the screw box by acting upon its toothed periphery.
In applying my Invention to metal knobs I make the shoulder of the
knob hollow or box form, in which hollow or box shoulder the screw
box c, e³, g, is enclosed, substantially as described and represented with
respect to the metal mount of a china or non-metallic knob.
5 Having now described the nature of my Invention and the manner in..
which the same is to be performed, I wish it to be understood that I do
not limit myself to the precise details herein described and illustrated, as
the same may be varied without departing from the nature of my
-

page_text: Invention; but I claim as my Invention the improvements in attaching
door and other knobs to spindles, herein-before described and illustrated
in the accompanying Drawing, that is to say, enclosing in a box or
hollow mount of a china or non-metallic knob, or in a hollow or
box shoulder of a metal knob, a screw box which works upon the 5
screwed spindle of the knob, the periphery of the said screw
box being made into a toothed wheel, by means of which toothed wheel
the rotation of the screw box enclosed in the box or hollow mount or
shoulder, and the adjustment of the knob are effected, the locking or
fixing of the screw box and the knob carrying it being effected by a 1
tooth or click jointed to the edge of the mount or shoulder engaging
between two of the teeth of the toothed wheel of the screw box, the
several parts being constructed, combined, and used substantially as
described and illustrated.
In witness whereof, I, the said Phinehas Edward Ayton, have 1
hereunto set my hand and seal, this Tenth day of June, in
the year of our Lord One thousand eight hundred and seventy-
five.
