County of Essex "IMPROVEMENTS IN THE MODE AND MEANS OF ATTACHING OR
FIXING OF KNOBS AND HANDLES TO SPINDLES OR SHANKS AND OF ADJUSTING

The object of my said invention is to provide a simple secure and efficient incans
of attaching or fixing and adjusting knobs and handles to spindles or shanks for
locks latches doors or drawers bell pull handles and other analogous purposes. I
construct door and other knobs with a central hole through the same. This hole
is inade in a direct line and its lower or base end is formed square or of other
suitable shape to receive a spindle or shank the hole at the other end or face of the
knob is tapped with a screw thread. The spindle or shank has a longitudinal hole
of convenient depth bored or formed and tapped with a screw thread to correspond
with screw thread to end or face of knob. A uniting screw is provided to fit the
screw threads at outer end or face of the knob and the screwed thread which has
been formed in the spindle.
I fix the knob to the spindle by passing the knob over the spindle to the
required distance of adjustment. I then insert the uniting screw into the screwed
thread at the outer end or face of the knob and turn it until it engages into the
screwed thread of the spindle, when the knob will be firmly connected to it the

"
The object of my said invention is to provide a simple secure and efficient means
of attaching or fixing and adjusting knobs and handles to spindles or shanks for
locks latches doors or drawers bell-pull handles and other analogous purposes. I
construct door and other knobs with a central hole through the same-This hole is
made in a direct line and its lower or base end is formed square or of other
suitable shape to receive a spindle or shank-The hole at the other end or face of
the knob is tapped with a screw-The spindle or shank has a longitudinal hole of
convenient depth, bored or formed and tapped with a screw thread to correspond
with the screw thread to the end or face of the knob-A uniting screw is provided
to fit the screw threads at the outer end or face of the knob and the screwed
thread which has been formed in the spindle.
I fix the knob to the spindle by passing the knob over the spindle to the
required distance of adjustment, I then insert the uniting screw into the screwed
thread at the outer end or face of the knob and turn it until it engages into the
screwed thread of the spindle when the knob will be firmly connected to it; the
uniting screw should then be screwed farther into the spindle until its end or head
is flush with the end or face of the knob.
In the case of lock knobs; the knob at one end of the spindle having been
adjusted and fixed in the manner before described the knob at the other end of
the spindle may be treated in the same way
Having thus stated the nature of my said invention I will proceed to describe
more particularly in what manner the same is to be performed by the aid of the
accompanying drawings in which similar letters indicate corresponding parts in the
two figures.
Fig: 1. represents one form of my invention (in section), a is the door, b the
position of a mortise lock, c the spindle and d, d, the handles. The spindle is
formed, as shewn, hollow at each end, the two ends being tapped to receive the

page_text: screw e which fits such screw thread-On fitting the handles to the spindle, one
handle is placed in position upon one end of the spindle; the screw e is then
inserted and screwed into the spindle, as shewn, and when the head of the screw is
flush with the handle, the second handle is fixed in a similar manner.
Fig: 2 represents a modification of my said invention in which the spindle c is
fitted with a male screw at each end, as shewn at e e, the uniting screws e¹. are
tapped inside to fit the screw e, and outside at f to fit the screw thread. cut in the
handle. The operation of fitting being similar to that herein before described
Having thus described and ascertained the nature and object of my said invention
I declare that what I claim and desire to be secured to me is:-
The general arrangement construction and combination of parts together
respectively forming my improvements in the mode and means of attaching or
fixing of knobs and handles to spindles or shanks and of adjusting the same
substantially as herein before described and shewn on the drawings.
In Witness whereof I the said Thomas Hungate Preston Dennis have hereunto
set my hand and seal this fifteenth day of November in the year of our
Lord One thousand eight hundred and eighty two.
