IMPROVED
HANDLES TO THEIR
My invention relates to means for attaching door, and other knobs, and handles
to their spindles. For the purpose of carrying my invention into practice, I pro-
vide an ordinary metal lock spindle of square section with a screw thread on the
angles of one end thereof. The plain end of the spindle I fix permanently by
coment, or otherwise into a combined rose, and knob. I then make a loose or
separate rose with a hole the diameter of the spindle through the centre of said
rose, and I also turn, cut, or mould within it, a recoss or rebate beyond the outer
diameter of the spindle-hole to form a seating for, a disc of metal, or other material,
and of such depth that when the disc referred to is bedded there shall be left a
space between the exposed or upper surface of the disc, and the upper edge of the
said rebate or recess in the said rose sufficient to allow a portion of the moveable
knob, or handle hereinafter described as it is screwed along the spindle to enter,
and thus conceal the metal or other locking parts, and at the same time to give the
effect of a combined rose, and knob as on the other end of the spindle. In the
centre of the disc of metal or other material I sink a circular robate or recess and
in the centre of such rebate or recess I cut a square hole right through the metal
in order that the disc may slide on the spindle, and I then bed such disc into the
recess in the rose, and fasten disc, and rose together by screws or otherwise. To
the outer and upper surface of the disc I rivet a steel hammer or catch, and either
rivet or solder a curved metal or other spring the one end of which actuates such
hammer or catch, and causes it to project beyond the edge of the rebate, or recess,
in the said disc, and, at the proper time to lift and tooth into cogs which are formed
all round the inner edge of another metal disc fixed into the second, or moveable
knob, and which is described hereinafter. The metal or other disc in the rose is
either screwed with wood screws to the rose, or fastened by projecting pins which
are cast, pressed, or otherwise made on the under side of the disc, and which answer
the purpose of nails, or keys for fastening the metal or other disc to the wood,

page_text: porcelain, or metal rose. In the case of porcelain, or metal these pins fit into sunk
recesses, or holes in the rose, and are securely keyed by cement or otherwise, thus
fastening the disc, and rose together. The rose, and metal or other disc thus com-
bined, and having a square hole through the centre, slide on the free or screwed
end of the spindle. I then mako a second knob, which is to be moveable, and I
turn or mould a circular hole of the necessary depth up the centre of it, making
the outer edge of the smaller end of the said last mentioned knob of the necessary
diameter to fit into the recess in the rose already described. I then tap or screw
the inside of a circular tubo of the necessary length to form a shank, and at one
end of the tube fix a metal disc with a circular hole in its centre, the diameter of
the spindle, the outer side of the disc surrounding the hole being solid, and the
front outer edge of such disc being rounded, or bevilled, and the back outer edge
thereof having cogs, or recesses in it in which the hammer or catch fixed on the
metal disc in the rose as is hereinbefore mentioned is to fit. This tube is then
driven into the turned hole in the herein before mentioned moveable knob until
the said cogs on the inner side of the disc at the end of the tube abut against the
knob when a complete and firm fastening of such knob to the spindle is effected in
the following manner. The free or screwed end of the spindle is put through the
lock until the fixed combined knob, and rose abut against the one side, and the
serowed end of the spindle projects it's full length on the other side thereof. The
combined metal, and wood, porcelain or metal rose is then slid on the spindle as
far as possible, and the hole being square the rose will not turn on the spindlo.
The moveable knob is then screwed home on the spindle, and as the metal disc
with rounded or bevilled edge on the end of the tube fixed in such knob travels
along the spindle, the said rounded or bevilled edge comes in contact with tho
hammer or catch (which also has a rounded or bevilled edge) on the rose disc, and
the said hammer is lifted, and when the-said disc-on--the--moveable knob.-has
travelled along the screwed spindle as far as it can into the recess in the metal
disc of the rose, the hammer is forced by the spring into cog, and the knob completely
locked on the spindle. Another way by which I effect this, is by screwing instead
of sliding the combined metal or other disc and rose on the spindle, and having a
square metal shank fitted into the moveable knob, such shank having on one end
the rounded or bevilled disc, and cogs as hereinbefore described, and I then slide
the moveable knob on the spindle until it engages with the catch on the rose disc,
and locks the whole, and on tho motal or other disc in the rose, I sometimes placo
one hammer, or catch, and one curved spring riveted or soldered at one end, the
opposite end acting on the hammer, or catch, and I sometimes have two hammers or
catches actuated by a curved spring riveted in the centre, both sides of which act
on the hammers respectively, and force them into the cogs. Another way by
which I effect the locking together of the disc in the rose, and the moveable knob
herein before mentioned is by using a rose disc in metal, or other material having on
it's face a hammer, or catch actuated by a spring, as also, a square hole through it's
centre, but without the circular recess or rebate herein before described, and on the
metal, or other shank fitted into the moveable knob, I use a disc having either
square notches, or holes in it's periphery, so that when the moveable knob is
screwed home on the spindle, the haminer or catch on the rose disc is forced into
one of the said notches or holes, and thus securely locks the said metal or other
rose, and moveable knob on the spindle. I also in some instances employ a ratchet
and pawl on the loose handle and rose respectively for the same purpose. Another
method is to drill holes in the periphery of the disc on the shank in the moveable
knob, and instead of employing a hammer, or catch and spring to use a projection
on the metal or other disc, and tap the same for a screw, and when the moveable
knob and disc are screwed home on the spindle to lock such knob and disc to the
metal or other disc and rose by means of two screws, one on the top of the other,
the upper screw having the effect of locking the lower one, and preventing it's
becoming loose.

page_text: For the purpose of taking the moveable knob off the spindle, I file a notch in
one end of the hammer or catch which acts as a lever, and opposite this notch I
drill a small hole through the rose so that by the aid of a bradawl, or other sharp
instrument, the notched end of the aforesaid lever being pressed down, the hammer
is lifted out of cog, and the knob can thus be unscrewed or drawn from the spindle
as the case may be thus completely liberating the spindle
