PROVISIONAL SPECIFICATION left by the said Benjamin Baugh and
Benjamin Walters at the Office of the Commissioners of Patents,
with their Petition, on the 12th April 1870.
WC, BENJAMIN BAUGH and BENJAMIN WALTERS, both of Birming-
ham, in the County of Warwick, Manufacturers, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN ATTACHING DOOR AND
OTHER KNOBS TO THEIR SPINDLES," to be as follows:―
Our Invention consists of the construction and arrangement of parts
herein-after described for attaching door and other knobs to their
spindles, whereby the moveable knob may readily be adjusted on its
spindle to the thickness of the door or other article and be securely
attached to the said spindle.

page_text: We will describe our Invention as applied to a pair of door knobs and
their spindle. We attach the fixed knob on the end of the spindle in
the usual way and we make on the other end of the spindle a screw
thread, on which screw thread a screw nut takes, as herein-after
described. We make the neck of the moveable knob to be fixed on the
screwed end of the spindle wider than usual, and we make the interior
of the said wide neck of a square or angular figure. Into this square
or angular neck a square or angular collar is fitted, the said angular
collar being capable of sliding upon and being adjusted on the screwed
end of the spindle. The adjusting of the sliding angular collar on the
spindle is effected by a screw nut screwed on the spindle at the rear
end of the said collar. The square or angular collar is fixed in the wide
neck of the knob by a screw pin passed through the neck of the knob
taking into a screwed hole in the said square or angular collar.
In attaching the moveable knob to its spindle according to our Inven-
tion we proceed as follows:-We pass the spindle through the lock and
door until the fixed knob bears against one side of the door. We then
place upon the screwed end of the spindle protruding from the opposite
side of the door the sliding angular collar herein-before described and
make its front end bear against the surface of the door. We next fix
the collar in its place on the spindle by means of a screw nut bearing
against the rear end of the collar. The screw nut may be prevented
from rotating on the spindle by a screw pin. We finally place the neck
of the moveable knob upon the angular collar fixed on the end of the
spindle, and attach the knob to the said collar by means of a screw pin
passed through the neck of the knob taking into a screwed hole in the
said collar. The moveable knob is thereby securely fixed to the spindle.
If desired the knobs at both ends of the spindle may be attached in the
manner described.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of April, in the year of
our Lord One thousand eight hundred and seventy, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said Benjamin Baugh and Benjamin Walters, Her
special licence that we, the said Benjamin Baugh and Benjamin Walters,
our executors, administrators, and assigns, or such others as we, the
said Benjamin Baugh and Benjamin Walters, our executors, adminis-
trators, 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 "IMPROVEMENTS IN ATTACHING
DOOR AND OTHER KNOBS TO THEIR SPINDLES," upon the condition (amongst
others) that we, the said Benjamin Baugh and Benjamin Walters, our
executors or administrators, by an instrument in writing under our or
their hands and seals, or under the hand and scal of one of us or them,
should particularly describe and ascertain the nature of the said Inven-
tion, 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 Benjamin Walters, on behalf of
myself and the said Benjamin Baugh, 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:
-
Our Invention consists of the construction and arrangement of parts
hercin-after described for attaching door and other knobs to their
spindles, whereby the moveable knob may readily be adjusted on its
spindle to the thickness of the door or other article and be securely
attached to the said spindle.
We will describe our Invention as applied to a pair of door knobs and
their spindle. We attach the fixed knob on the end of the spindle in
the usual way, and we make on the other end of the spindle a screw
thread, on which screw thread a screw nut takes, as herein-after
described. We make the neck of the moveable knob to be fixed on the
screwed end of the spindle wider than usual, and we make the interior
of the said wide neck of a square or angular figure. Into this square or

page_text: angular neck a squaro or angular collar is fitted, the said angular collar
being capable of sliding upon and being adjusted on the screwed end of
the spindle. The adjusting of the sliding angular collar on the spindle
is effected by a screw nut screwed on the spindle at the rear end of the
said collar. The square or angular collar is fixed in the wide neck of
the knob by a screw pin passed through the neck of the knob taking
into a screwed hole in the square or angular collar.
In attaching the moveable knob to its spindle according to our
Invention we proceed as follows:-We pass the spindle through. с
lock and door until the fixed knob bears against one side of the door.
We then place upon the screwed end of the spindle protruding from the
opposite side of the door the sliding angular collar hercin-before described
and make its front end bear against the surface of the door. We next
fix the collar in its place on the spindle by means of a screw nut bearing
against the rear end of the collar. The screw nut may be prevented
from rotating on the spindle by a screw pin. We finally place the neck
of the moveable knob upon the angular collar fixed on the end of the
spindle, and attach the knob to the said collar by means of a screw pin
passed through the neck of the knob taking into a screwed hole in the
said collar. The moveable knob is thereby securely fixed to the spindle.
If desired the knobs at both ends of the spindle may be attached in the
manner described.
Having explained the nature of our Invention, we will proceed to
describe with reference to the accompanying Drawing the manner in
which the same is to be performed.
Figure 1 represents in vertical section the moveable knob of a pair of
door knobs attached to its spindle according to our Invention, and
Figure 2 represents the same before the moveable knob is attached to
its spindle; Figures 3, 4, and 5 represent parts of the same separately,
as hercin-after described. The same letters of reference indicate the
same parts in each of the Figures of the Drawing,
a is the fixed knob secured to one end of the spindle 6 in the usual
way; c is the moveable knob attached to the spindle according to
our Invention. A back clevation of the knob c detached is represented
in Figure 3. One end of the spindle is screwed, and on the said
screwed end a screw nut d takes. This screw nut is shown detached in
Figure 5. On the screwed end of the spindle in front of the screw
nut d is a sliding square or angular collar e, the said collar being slightly

page_text: taper. This angular collar is shown separately in Figure 4. The neck
of the knob c is made considerably wider than that of the ordinary knob,
and the interior of the said wide neck is made square or angular to fit
upon the square or angular collar e. The shape of the interior of the
neck of the knob c is best seen in Figure 3. In attaching the moveable
knob c to its spindle we proceed as follows:-The spindle with
the fixed knob a on one end is passed through the opening in the lock
and door until the face of the said fixed knob a bears against the said
door, as seen in Figure 2. We now place upon the screwed end of the
spindle protruding from the opposite side of the door the sliding
collar c, the front end of the said sliding collar being made to abut
against the surface of the door. We next fix the adjusted collar e in its
place on the spindle by screwing the screw nut d on the spindle until
the said nut bears against the rear end of the said collar e.
The parts
now occupy the positions represented in Figure 2 and the spindle is
ready to receive the moveable knob c. The neck of the moveable
knob c is next placed upon the now fixed collar e, and the said knob is
attached to the said collar by means of the screw pin f passed through
the neck of the knob taking into a screwed hole in the collar e, as
illustrated in Figure 1. The moveable knob c is thereby securely fixed
to the spindle. The knob a may be fixed to the spindle by the arrange-
ment of parts described with respect to the knob c. In order to prevent
the screw nut & from rotating on the spindle after it has fixed the
adjusted sliding collar e in its place the said nut may be fixed by a screw
ping, as illustrated in Figure 6, taking into or bearing against the
spindle before the knob is attached to the collar and spindle.
Ilaving now described the nature of our Invention, and the manner
in which the same is to be performed, we wish it to be understood that
we do not limit ourselves to the precise details herein described and
illustrated, as the same may be varied without departing from the
nature of our Invention; but we claim as our Invention, the improve-
ments in attaching door and other knobs to their spindles herein-before
described and illustrated in the accompanying Drawing, that is to say,
making the interior of the neck of the knob to be fixed on the spindle of
a square or angular figure and of considerably greater diameter than the
spindle of the knob, and attaching the said knob to the spindle by fitting
it upon and fixing it to a square or angular collar which has been

page_text: previously adjusted and fixed on the spindle, substantially as described
and illustrated.
In witness whereof, I, the said Benjamin Walters, have hereunto
set my hand and seal, this Twenty-ninth day of September, in
the year of our Lord One thousand eight hundred and seventy.
