page_text: LETTERS PATENT to Franklin Davies, of the Firm of S. Mills and Company, of
Birmingham, in the County of Warwick, Carriage Brassfounders, for the
Invention of "IMPROVEMENTS IN ATTACHING THE HANDLES OR KNOBS OF
CARRIAGE AND OTHER DOORS TO THEIR SPINDLES, AND IN ATTACHING THE
SPINDLES OF HANDLES OR KNOBS TO CUPBOARD AND OTHER DOORS."
PROVISIONAL SPECIFICATION left by the said Franklin Davies at the Office
of the Commissioners of Patents on the 7th June 1879.
FRANKLIN DAVIES, of the Firm of S. Mills and Company, of Birmingham, in the
County of Warwick, Carriage Brassfounders. "IMPROVEMENTS IN ATTACHING THE
HANDLES OR KNOBS OF CARRIAGE AND OTHER DOORS TO THEIR SPINDLES, AND
IN ATTACHING THE SPINDLES OF HANDLES OR KNOBS TO CUPBOARD AND OTHER
DOORS."
My Invention has reference principally to the attaching of the inside handles of
carriage doors to their spindles, and I will describe my Invention as applied to such
handles, but my said Invention may also be applied to the attaching of other door
handles or knobs to their spindles, and to the attaching of the spindles of handles
or knobs to cupboard and other doors.
In attaching the inside handle of a carriage door to its spindle according to my
Invention I construct and combine the parts in the following way:-I make the
barrel or hollow head of the inside handle cylindrical at its rear part and square at
its front part, to receive the square spindle, which said spindle is screwed on its
angles as usual.
The junction of the cylindrical rear part of the barrel with the square front part
forms a shoulder or stop. In the cylindrical part of the barrel a rotating screw box
works, the rear or outer end of the said screw box being provided with a hexagonal
or other angular head for turning it, the said head being made solid to or in one
piece with the said screw box. When the screw box is introduced into the cylin-
drical rear part of the barrel its front end abuts against the shoulder or stop where
the square part sets in and its rear end closes the said barrel, the angular head of
15

page_text: the screw box being situated external to the said barrel. The screw box is secured
in the barrel, and its rotation therein permitted by the following arrangements of
parts-In the exterior of the screw box I make an annular groove having in cross
section a semi-circular figure, and I make in the interior of the cylindrical part of
the barrel a similar annular groove, so that when the screw box is pushed hone in
the barrel against its abutment or stop at the square part, the two annular grooves
come opposite one another, and form between them a groove having a circular
figure in cross section. An oblique slot is drilled from the exterior of the barrel,
and made to open into the groove described between the barrel and screw box. By
passing a wire through this oblique slot it enters into and fills up the greater part
of the annular grooves forming a nearly complete collar between the barrel and
screw box. The external end of the wire collar being cut off, the oblique slot
through which it was passed is plugged up and the screw box is securely fastened
in its place in the barrel, the screw box being free to rotate in the said barrel.
Or instead of the wire collar described a pin or pins may be passed through a hole
or holes in the barrel, and made to engage in the annular groove between the screw
box and barrel with the same or nearly the same effect.
In attaching the inside carriage door handle constructed as described to its
screwed spindle the square end of the barrel is passed onto the protruding end of
the spindle, and the screw box is rotated by means of a key, spanner, or other
instrument fitted on its angular external head. The screw box is thereby made to
advance upon
the screwed spindle, and slide the barrel thereon until the front end
of the said barrel abuts against the door. The removal of the handle from the
spindle is effected by reversing the motion of the screw box so as to cause the barrel
to retire from off the end of the screwed spindlo.
In applying my Invention to the attaching of door handles other than inside
carriage door handles to their spindles I construct and arrange the parts substan-
tially as described with respect to an inside carriage door handle.
My Invention is applicable to the attaching of spindles having a handle or knob
at one end only, to doors such, for example, as the spindles of cupboard turns.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Franklin Davics in the Great Seal Patent Office on the 2nd
December 1879.
FRANKLIN DAVIES, of the Firm of S. Mills and Company, of Birmingham, in the
County of Warwick, Carriage Brassfounders. "IMPROVEMENTS IN ATTACHING THE
HANDLES OR KNOBS OF CARRIAGE AND OTHER DOORS TO THEIR SPINDLES, AND
IN ATTACHING THE SPINDLES OF HANDLES OR KNOBS TO CUPBOARD AND OTHER
Dooks."
My Invention has reference principally to the attaching of the inside handles of
carriage doors to their spindles, and I will describe my Invention as applied to such
handles, but my said Invention may also be applied to the attaching of other door

page_text: handles or knobs to their spindles and to the attaching of the spindles of handles
or knobs to cupboard and other doors.
In attaching the inside handle of a carriage door to its spindle according to my
Invention, I construct and combine the parts in the following manner:-I make
the barrel or hollow head of the inside handle cylindrical at its front part and
square at its rear part to receive the square spindle, which said spindle is screwed
on its angles as usual. The junction of the cylindrical part of the barrel with the
square part forms a shoulder or stop. In the cylindrical part of the barrel a rotating
screw-box works, the rear or outer end of the said screw box being provided with a
hexagonal or other angular head for turning it, the said head being made solid to or
in one piece with the said screw-box. When the screw-box is introduced into the
cylindrical part of the barrel its front end abuts against the shoulder or stop whore
the square parts sets in, and its other end closes the said barrel, the angular head of
the screw box boing situated external to the said barrel. The screw-box is secured
in the barrel, and its rotation therein permitted by the following arrangement of
parts:
In the exterior of the screw box I make an annular groove having in cross section
a semi-circular figure, and I make in the interior of the cylindrical part of the barrel
a similar annular groove, so that when the screw box is pushed home in the barrel
against its stop or abutment the two annular grooves come opposite one another,
and form between them a groove having a circular figure in cross section. An
oblique slot is drilled from the exterior of the barrel, and made to open into the
groove described between the barrel and screw-box. By passing a wire through
this oblique slot it enters into and fills up the groater part of the annular groove,
forming a nearly complete collar between the barrel and screw-box. The external
end of the wire collar being cut off, the oblique slot through which it was passed is
plugged up and the screw box is securely fastened in its place in the barrel, the
screw-box being free to rotate in the said barrel.
I will now proceed to describe, with reference to the accompanying Drawing, the
manner in which my Invention may be performed.
Figure 1 represents in front elevation, Figure 2 in side elevation, and Figure 3
in longitudinal section, the inside handle of a carriage door attached to its spindle
according to my Invention; Figure 4 represents in longitudinal section the inside
handle and its barrel or tubular head detached from the spindle; Figure 5 repre.
sents in elovation, and Figure 6 in longitudinal section, the screw box detached;
Figure 7 represents a back elevation of the handle; Figure 8 represents in cross
section the handle before the wire collar is fixed in its place; and Figure 9 repre-
sents the same view as Figure S after the wire collar has been fixed in its place.
The same letters indicate the same parts in the several Figures of the Drawing.
a is the inside carriage handle, and b is the barrel or tubular head of the same,
the said head b being cylindrical at c for receiving the screw-box d, and square at e
for receiving the square spindle f, which is screwed on its angles as represented.
The junction of the cylindrical part c with the square part e forms a shoulder or
stop at g. The screw box d, which rotates in the cylindrical part c of the barrel b,
has at its outer end a hexagonal or other angular head for turning the said screw
box. This angular head is made solid to or in one piece with the screw box d, as
seen in Figures 3 and 6. The inner end of the screw box d abuts against the
shoulder g when introduced into the barrel or tubular head b of the handle; i is an
aunular groove made in the exterior of the screw box (, and is a similar annular
groove inade in the interior of the barrel 6 of the handle. Each of the grooves i, k,
is semi-circular in cross section. When the screw box d is introduced into the
barrel b, and pushed home to the shoulder or stop g, the annular groove i in it
comes opposite the annular groove k in the barrel b, and a groove marked I, having
a circular figure in cross section, is thereby formed between thein, as seen in Figures
3 and 8. An oblique or nearly tangential slot at opens from the outside of the
barrel b into the groove l, as seen in Figures 8 and 9. By forcing a piece of cylin-
drical wire m, Figure 8, through the slot, it enters and partly fills up the annular

page_text: groove l, forming a nearly complete collar m between the barrel & and the screw
box b, as seen in Figures 3 and 9. The external end of the wire collar m being cut
off, the slot at P, if necessary, may be plugged up. By this arrangement the screw
box d is securely fastened in its place in the barrel b of the handle, the said screw
box being free to rotate in the said barrel.
Instead of the wire collar m a pin or pins may be passed through a cross hole or
holes in the barrel b, and made to engage in the annular groove between the screw-
box and barrel with the same or nearly the same effect.
In attaching the inside carriage door handle a, constructed as described and
illustrated, to its screwed spindle f, the square end e of the barrel b is passed onto
the protruding end of the spindle f, and the screw box d is rotated by means of a
key, spanner, or other instrument fitted on its angular external head h. The screw
box d is thereby made to advance upon the screwed spindle f, and slide the barrel b
thereon until the end 63 of the said barrel abuts against the door. The removal of
the handle a from the spindle f is effected by reversing the motion of the screw
box d, so as to cause the barrel to retire from off the end of the screwed
spindle f
In applying my Invention to the attaching of door handles other than inside
carriage door handles to their spindles I construct and arrange the parts substan-
tially as described and illustrated with respect to an inside carriage door handle.
My Invention is applicable to the attaching of spindles having a handle or knob
at one end only to doors, such for example, as the spindles of cupboard turns. In
the case of cupboard turns, the handle a is replaced by the button or arm of the
cupboard turn, and the spindle is made cylindrical at that part which passes
through the door, the said spindle f having the outside knob of the cupboard turn
upon it. In attaching knobs directly to doors the screwed end of the spindle f is
passed through the door, and adjusted and fixed on the inside of the door by means
of the tubular head and screw box b, h, d, the handle a being omitted. The outside
knob is fixed to the unscrewed end of the spindle f.
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 claim as my Invention,
first, the improvements in attaching the handles or knobs of carriage and other
doors to their spindles herein before described, and illustrated in the accompanying
Drawing; that is to say, the arrangements or combination of parts described and
illustrated for securing the screw box in the barrel or tubular part of the inside or
other handle or knob, while the said screw box is free to rotate in the said barrel or
tubular part, the said securing parts consisting of the angular grooves i, i, in the
barrel and screw box, into which grooves, when brought together, a wire collar is
forced, and made partly to fill up, or into which grooves a cross pin or pins is or
are passed, as described and illustrated.
Secondly. The application of the parts herein before described and claimed in the
first claim to the attaching of the spindles of handles or knobs to cupboard and
other doors.
In witness whereof, I, the said Franklin Davies, have hereunto set my hand
and seal, this Twenty-fourth day of November, in the year of our Lord One
thousand eight hundred and seventy nine.
