IMPROVEMENTS IN MEANS FOR ADJUSTING DOOR KNOBS ON THEIR SPINDLES
Year: 1884

page_text: I CHARLES TIGHE of 42 Lombard Street in the City of London, Hosier and
Outfitter do hereby declare the nature of the said Invention for IMPROVEMENTS
IN MEANS FOR ADJUSTING DOOR KNOBS ON THEIR SPINDLES to be as follows :-
The invention has for its object a simple and effective method of adjusting door
knobs on their spindles, whereby a sufficiently accurate adjustment can be obtained
combined with solidity of union between the parts.
For this purpose I fix one of the knobs rigidly on the spindle, whilst I form the
latter with a series of holes or teeth to provide for the adjustment of the inoveable
knob thereon. In the collar of the moveable knob I form a hole or slot extending
from the periphery thereof down to the spindle and in such hole or slot I place
a moveable tooth or peg which acts in combination with one or other of the
teeth or holes in the spindle.
The collar of the knob is formed on its periphery with a screw thread to receive
a covering collar or rose which serves to hold the tooth or peg in position and at
the same time to make a neat finish.
If desired however the covering collar or rose instead of being screwed on to
the collar of the knob may be provided with one or more holes and screwed to
the door.
In order to provide for further slight adjustment I place as may be required a
washer of cloth or other suitable material between the collar of one or both knobs
and the door.

page_text: shown on two of its sides to provide for the adjustment of the moveable knob c
thereon. In the collar c¹ of the moveable knob c I form a hole or preferably as
shown a slot c³ extending down the spindle a and in such hole or slot c³ I place a
moveable peg or tooth d which acts in combination with one or other of the holes
or teeth af in the spindle a.
The collar c' of the knob c according to the arrangement shown at Figures 1 to 6
is formed on its periphery with a screw thread to receive a covering collar or rose e
which serves to hold the peg or tooth d in position and at the same time to make
a neat finish.
If desired the covering collar or rose e instead of being screwed on to the
collar c' of the knob c may as shown at Figures 7, 8, 9 be provided with one or
more holes e¹ and screwed to the door.
In order to provide for further slight adjustment I place as may be required a
washer of cloth or other suitable material between the collar of one of the knobs
and the door.
In the drawings such washer is shown applied between the collar c¹ of the
knob c and the metallic washer g which rests against the door.
The holes or teeth a¹ on one side of the spindle a are placed at distances
intermediate of those on the adjacent side in order to obtain finer adjustment
than can be obtained with a series of holes or teeth a' on only one side of the
spindle a.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
A knob c provided with a hole or slot c³ in its collar c¹ to receive a peg or
tooth d which acts in combination with one or other of the holes or teeth a¹ on
the spindle a and which is retained in position by a covering rose e substantially
as herein shown and described and for the purpose stated.
