Year: 1869

page_text: LETTERS PATENT to Philippe Koch, of the City of Manchester, in the
County of Lancaster, for the Invention of "IMPROVED MODES OF
FASTENING THE KNOBS OR HANDLES OF LOCKS AND LATCHES OF DOORS AND
GATES, AND FOR OTHER SIMILAR PURPOSES." -A communication from
abroad by Charles Bristol, of New Haven, Connecticut, U.S. of
America.
Sealed the 19th April 1870, and dated the 15th November 1869.
PROVISIONAL SPECIFICATION left by the said Philippe Koch at the
Office of the Commissioners of Patents, with his Petition, on the
15th November 1869.
I, PHILIPPE Kоcи, of the City of Manchester, in the County of
Lancaster, do hereby declare the nature of the said Invention for " Ix-
PROVED MODES OF FASTENING THE KNOBS OR HANDLES OF LOCKS AND LATCHES OF
DOORS AND GATES, AND FOR OTHER SIMILAR PURPOSES," being a communication
to me from abroad by Charles Bristol, of New Haven, Connecticut,
C.S. of America, to be as follows:-
This Invention consists of improved modes of fastening knobs or
handles to the tumbler shafts of locks and latclics and holding ferrules

page_text: to the sides of doors. Instead of forming recesses at the ends of the
tumbler shafts for the points of the fastening screws to enter I form at
the ends of the shafts inclined planes descending inwards, so that when
the knobs are placed on the shafts and the screws screwed tight the
higher parts of the inclines behind the screws prevent the knobs from
loosening and coming off, and at the same time the inclines enable the
knobs to be adjusted with exactness to various thicknesses of doors and
gates.
Instead of making the insides of the ferrules used for doors perfectly
even I form pins or projections upon them, which are forced into the
sides of the door to prevent the ferrules from turning.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Philippe Koch in the Great Seal Patent Office on
the 13th May 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PHILIPPE
Kocи, of the City of Manchester, in the County of Lancaster, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of November, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-third year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Philippe Koch, Her special
licence that I, the said Philippe Koch, my executors, administrators,
and assigns, or such others as I, the said Philippe Koch, my exe-
cutors, administrators, and assigns, should at any time agree with, and
no others, from time to time and at all times thereafter 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 "IMPROVED MODES
OP FASTENING THE KNOBS OB HANDLES OF LOCKS AND LATCHES OF DOORS AND
GATES, AND FOR OTHER SIMILAR PURPOSES," a communication to me from
abroad by Charles Bristol, of New Haven, Connecticut, United States of
America, upon the condition (amongst others) that I, the said Philippe
Koch, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and scals, should particularly.

page_text: 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 Philippe Koch, do hereby declare
the nature of the said Invention, and in what manner the same is to
bo performed, to be particularly described and ascertained in and by
the following statement thereof, reference being had to the figures on the
accompanying Sheet of Drawings, and to the letters of reference marked
thereon (that is to say):-
This Invention consists of improved modes of fastening knobs or
handles to the tumbler shafts of locks and latches and holding ferrules
to the sides of doors. Instead of forming recesses at the ends of the
tumbler shafts for the points of the fastening screws to enter I form on
the angles at the ends of the shafts inclined planes descending inwards,
so that when the knobs are placed on the shafts and the screws screwed
tight the higher parts of the inclines behind the screws prevent the
knobs from loosening and coming off, and at the same time the inclines
enable knobs to be adjusted with exactness to various thicknesses of
doors and gates.
Instead of making the insides of ferrules used for doors perfectly plain
I form on them pins or projections, which are forced into the sides of the
doors to prevent the ferrules from turning.
On the accompanying Sheet of Drawings Fig. 1 is a view partly in
section of a knob, cap, and ferrule at one end of a tumbler shaft, having
inclines on the angles at both ends; Fig. 2, an end view of the shaft;
Fig. 3, a sectional view of a knob at one end and an external view of
another knob at the other end of a shaft with inclined ends on the
angles; Fig. 4 an external view of a knob and inclined shaft adapted for
stationary purposes, such as the outsides of drawers, doors, and gates;
and Figs. 5 and 6 are external views of a knob and inclined shaft
adapted to an ordinary cupboard door latch. In all the Figures the
inclines on the angles at the ends of the shafts are marked a, and it is
evident that when the screws 6 are screwed tight that the knobs cannot
move back. In Fig. 1 in addition to the cap c there is a ferrule & for
the shaft to work in, and this ferrule has pins e which are forced into
the side of the door.

page_text: Having now described the nature and particulars of the said Invention
as communicated to me, I desire it to be understood that I claim, the
improved modes of fastening the knobs or handles of locks and latches of
doors, and gates, and for other similar purposes, as herein described and
illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said Philippe Koch, have hereunto set
my hand and seal, this Twelfth day of May, in the year of our
Lord One thousand eight hundred and seventy.
PHILIPPE KOCH. (L.S.)
