I, ALBERT EDWARD WHITE, of the Village of Dutton, in the County of
Elgin, in the Province of Ontario, Canada, Hardware Merchant, do hereby
declare the nature of this invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to devices for securing and rigidly holding the adjustable
knob at any point required on the spindle.
The practice in general use of securing door knobs to the spindle, is by set screws
extending through the shank or face of the knob, and engaging with sockets in the
spindle, the objection to these screws is, that they are continually working loose
with wear, or the sockets to receive the screws are too wide apart, and thereby
permit the knob and spindle to move lengthwise and rattle in the door; all of
which is avoided and completely prevented by using my invention.
My invention consists of the improved construction and new combination of
parts, as will be hereinafter first fully set forth and described, and then pointed out
in the claims.
.
Reference being had to the accompanying drawings, wherein.
Fig. 1. is a central longitudinal sectional view of a door knob and attachments,
embodying my invention.
Fig. 2. is a cross sectional view on the line, x, x, of Fig. 1. looking towards the
knob.
Fig. 3. is a cross sectional view on the line, x, x, of Fig. 1. looking towards the
washer.
Fig. 4. is a cross sectional view on the line, a, a, of Fig. 1. looking towards
the nut.
Fig. 5. is a detail side and end view of the washer and modifications thereof.
Fig. 6. is a detail side and end view of the nut.
In the annexed drawings, S, designates a spindle; and, K, K', the door knobs,
one of which knobs, K', is shown secured to one end of said spindle, by being
formed integral therewith, but it may be secured thereto, in any other suitable
manner. On the other end of the spindle, S, is formed the screw threaded
corners, G; and the shank, H, of the adjustable knob, K, is formed with a circular
screw threaded socket, E, to which the screw threaded corners, G, of the spindle, S,
are fitted.
W, designates a washer formed with an opening, O, baving a segmental or
angular face, F, as shown in Fig. 5. to which the spindle, S, is fitted.

page_text: N, designates a nut, having a circular-screw threaded socket, I, to which the
screw threaded corners, G, of the spindle, S, arc fitted.
D. designates the door; and, L, the lock secured thereto.
The method of attaching the adjustable knob, K, to the spindle is as follows.-
The spindle, S, is projected through the door, D, and lock, L, until the shank of
the knob, K', rests against the lock, L, or against a plate, R, on the adjacent side
of said door, or against the door; when in this position, the threaded end, G, of
the spindle, S, projects beyond the door at the opposite side; the nut, N, is then
turned on this end of the spindle, until it abuts against the plate, R, permitting the
spindle and knob to turn perfectly free without any motion lengthwise thereof; the
washer, W, is then placed on the spindle, and adjusted against the nut, N, the screw
threaded socket of the knob shank, H, is then engaged with, and screwed up on the
spindle until the washer is rigidly bound against the nut, N; and the washer, W,
having an opening formed with a segmental or angular face, F, as shown in Fig. 5.
engaging with a corresponding face or recess on the spindle, S, the nut is prevented
from turning further on the spindle, and thereby prevented from binding on the
door, and the nut, washer, knob and spindle are rigidly bound together.
By tightening the knob, K, with a wrench or other similar means, said knob
may be made to bind on the washer, W, and the latter against the nut, N, to
prevent said knob from being turned off, unless by the application of a power equal
to that used wher. tightening same.
At, W, Fig. 5. a washer is shown with a square opening, but this opening may
be triangular, or of any other suitable shape, to this opening, the spindle is
fitted.
At, W₁, Fig. 5. a washer formed with an opening, having a segmental face is
shown, which is intended to engage with a correspondingly shaped spindle, but one
or more of these segmental faces may be formed in the opening, O, and on the
spindle as desired.
At, W, and, W³, Fig. 5. washers are shown with openings having internal
angular projections, which are intended to engage with corresponding recesses in
the spindle, S, or vice versa, the projections may be formed on the spindle, and the
corresponding recesses in the washer, and these internal projections may be of any
number or of any shape, according to the fancy or taste of the manufacturer.
At, W, Fig. 5. a washer is shown having an opening cut therein from one side,
a washer of this construction, may be placed in position after the knob is partly
screwed on the spindle.
The washers shown at, W, and, W, are intended to be used with a square or
other angular shaped spindle, formed with screw threaded corners, G, while the
washers, W', W, Ws, are intended to be used with a round spindle, having screw
threads formed thereon.
Whichever of these forms of a washer is used, the segmental or angular face, F,
of the opening, engages with a corresponding face or recess in the spindle, so that
when the nut, N, is properly adjusted to permit the knob, K, and spindle, S, to
turn perfectly free, but not to move longitudinally in the door, it is rigidly held at
this point, by interposing a washer, W, between said nut and the adjustable knob,
and screwing up the latter to bind said washer against said nut.
This provides inexpensive devices for rigidly holding the knob on the spindle,
which devices are at the same time, strong, durable, and not liable to get out of
repair, and practically everlasting; and by which, all rattle of the knob and nnt,
and all movement of the spindle lengthwise, is avoided and completely prevented;
by which the knob or spindle cannot work loose with wear; by which the knob
can be adjusted instantly to the thickness of the door; and by which the
objectionable screws generally used through the shank or face of the knob for this
purpose, are avoided and completely dispensed with.
And while I prefer the construction shown, I do not limit myself to the details,
as they may be modified in various ways without departing from the spirit of my
invention.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.
1st. The spindle having a knob rigidly secured to one end, and its other end
screw threaded, combined with a tubular screw threaded nut, a non rotating washer
placed on the spindle next to the nut, and the removable knob, having a screw
threaded socket to receive the end of the spindle, substantially as shown and
described, and for the purpose specified.
2nd. The spindle having a knob rigidly secured to one end, and its other end
formed angular or semicircular and screw threaded, combined with a tubular screw
threaded nut, a non rotating washer placed on the spindle next to the nut, and the
removable knob, having a screw threaded socket to receive the end of the spindle,
substantially as shown and described, and for the purpose specified.
3rd. The spindle rectangular in cross section, and having a knob rigidly secured
to one end, and its other end screw threaded, combined with a tubular screw
threaded nut, a non rotating washer formed with a rectangular opening, and placed
on the spindle next to the nut, and the removable knob, having a screw threaded
socket to receive the end of the spindle, substantially as shown and described and
for the purpose specified.
