Claims. (Cl. 292347) This invention has reference to improvements relating to door furniture.

' It is desirable that door furniture should be capable of being fitted to doors of varying thicknesses, and the present invention has for its object to provide an improved method of and means for achieving this purpose.

Accordingly the invention consists of an improved method of fitting door furniture to doors and resides in the characteristic steps of forming in that side of the door on which a free handle or knob is to be fitted a recess which is coaxial with a hole provided for the passage of the customary non-circular operating spindle to which a free handle or knob is to be secured, fitting within'the said recess a cup which is capable of a rotation relatively to said spindle and which is provided with a screw-threaded portion, securing the cup within the recess by means of a nut which is adapted to engage a screw-threaded portion of said operating spindle and to be located within the cup when occupying the securing position, sliding the recessed boss of the free handle or knob over the projecting end of the spindle in a non-ro tational relationship therewith and then engaging with the screw-threaded portion of the cup a complementary screw-threaded portion on the boss of the said handle or knob and subsequently rotating the cup to draw the handle or knob into abutment therewith and thereby to secure the free knob or handle to the spindle.

The invention also consists in the association with door furniture of a cup which is adapted to be turnably fitted within a recess in that side of the door on which a free "handle or knob is required to be fitted and which is .Co-axial with the hole provided for the customary noncircular operating spindle, said cup having a hole in the bottom thereof which permits of the cup being turned on the spindle after the spindle has been threaded through the said hole and a screw-threaded portion adapted to cooperate with a complementary screw-threaded portion at the recessed end of the free handle or knob which is to be fitted to thespindle, a nut adapted to be threaded on to a screw-threaded portion of the spindle and to be located within the interior of the cup when the said cup has been inserted within the recess as aforesaid, and means associated with the nut and with the free handle orknob for locking the nut to the said free handle or knob when the screw-threaded portion of the free handle or knob is engaged with the screw-threaded portion 2,947,561 Patented Aug. 2, 1960 rah furniture for use in conjunction with a mortice type lock of known construction.

Figure 4 is a fragmentary view in section on the plane indicated by the line 4-4, Figure 2, looking in the direction of the arrows to the said line.

In the drawings like numerals of reference indicate similar parts in the several views.

According to the illustrated embodiment of the invention the door furniture is of the type in which the latch bolt 10 is adapted to be actuated through the medium of a spindle 11 of square cross section which is passed through a rectangular hole in the door 12 and through a rectangular hole in the latch bolt 10 said spindle 11 having fixed on one end thereof in conventional manner 1 an operating lever handle 13 hereinafter termed the fixed handle 13 and in which a similar operating lever handle.

14 hereinafter termed the free handle 14 is required to be fitted detachably on the screw-threaded opposite end portion 111 of the spindle 11 to that on which the fixed.

handle 13 is secured.

\ The door 12 to which the door furniture is to be fitted is provided on that side on which the free handle 14 is to be located with a recess 121 which is co-axial with the hole provided for the spindle 11.

Adapted to be fitted within the recess 121 is the inwardly disposed portion 151 of a cup 15, said cup 15 being provided in the bottom with a hole 152 which permits of the spindle 11 being freely turn-able relativelyto the cup 15.

The cup 15 is provided with a flanged head 153 of a diameter greater than the diameter of the recess 121 and the said cup 15 is screw-threaded internally as at 154 fora purpose to be described hereinafter. The flanged head 153 of the cup 15 is formed with flats 155 for engagement by a tool for effecting rotation of the cup 15 also for a purpose to be described hereinafter.

Further the flanged head 153 is formed with a tapped hole 156 for engagement by a grub screw 16.

Adapted to be screwed on the screw-threaded projecting end portion 111 of the spindle 11 after the said spindle has been passed through the usual square hole in the latch .bolt actuating member (not shown) is a circular nut 17 of a diameter less than the internal diameter of the cup 15 and of a depth such that when screwed on to the spindle 1-1 in the manner required the said nut 17 will be located within the inner end por; tion 151 of the cup 15 and engage the bottom thereof. The nut 17 is provided with oppositely disposed tongues 171 which are adapted to engage within slots 141 in the screw-threaded portion 142, provided on the boss 143 of the. free lever handle 14, said boss 143 being formed with the customary square hole 144 for engagement by the projecting end portion of the spindle 11. The screw-threaded portion 142 of the free handle 14; is adapted to cooperate with the screw-threaded portion 154 of the cup 15 in a manner to be described hereinafter.

As is common practice a pronged washer 18 is adapted .to be fitted to the door 12 before the insertion of the cup 15 in the recess 121 and the usual rose plate 19 is provided for concealing the manner of fitment of the free handle 14 and for enhancing the appearance of the door iurniture as a whole, a similar pronged washer 20 and a rose plate 21 are associated with the fixed handle 13. r

Door furniture as hereinbefore described isiitted to a door by passing the free end of .the spindle 11 to which washer 18 is then secured to the door 12 coaxially with.

the recess 121. The inner portion 151 of the cup 15 is then passed through the hole in the washer 18 and inserted in the recess 121' whereupon the nut 17 is engaged with the spindle 1-1 and turned forcing the cup inwardly until the inner face of the flanged head 153 abuts the outer face of the washer 18 with the tongues 171 of the nut 17 projecting outwardly. The rose plate 19 is then passed on to the free handle 14 so as to be located on the boss 143 of the said free handle 14.

The recessed boss .143 of the tree handle 14 is then passed over theprojecting end portion 111 of the spindie 11 in a manner such that the slots 141 in the screwthreaded portion 142 are caused to be engaged by the tongues 171 of the nut 17 and the screw-threaded portion .142 to engage with .the internal thread of the screwthreaded portion 154 of the cup 15.

The cup 15 is then turned by engaging a tool with the flats 155 whereupon the turning of the cup 15 by reason of the engagement of the screw-threaded portion 142 of the tree handle boss 143 with the screw-threaded portion 150 of the cup 15 occasions the boss 143 of the free handle .14 being drawn toward the flanged head 153 of the cup 15 while the nut 17 holds the cup against outward displacement. Turning of the cup 15 is continued until the face of a shoulder 145 on the boss 143 of the free handle 14 abuts the outer face of the flanged head 1153 of the cup 15 whereupon the grub screw 16 is inserted in the tapped hole 156- and screwed home. Subsequently the rose plate 19 is fitted in the customary manner. 7 7

It will be appreciated that the nut 17 prevents withdrawal of the cup 15 from within the recess 121 and that the engagement of the tongues 171 on the nut 17 within the slot 141 in the screw-threaded portion or stem 142 of the boss 143 prevents rotation of the nut 17 during rotation of the cup 15 since the tree handle 14 cannot turn relatively to the spindle 11.

It will be understood that knobs may be substituted for the

handles

13 and 14 if so preferred.

If desired the nut 17 may be provided with a single tongue 171 and the screw-threaded portion 142 with one or more slots 141 for engagement therewith.

Furthermore if desired each handle or knob may be fitted to the operating spindle in the manner hereinbefore described.

It will be appreciated that the method of fixing permits of door handles or knobs being fitted to doors of varying thicknesses. I Moreover it will be appreciated if desired that the cups 15 may be made of a standardised size it only being necessary when fitting door furniture to select a cup of the appropriate depth to flt in a recess 121 when formed in the door.

I claim:

1. Door furniture including in combination a handle having a threaded spindle arranged to pass through the door and emerge in a concentric recess therein, a cup fitted within the recess and having a flanged bottom perforated to receive the spindle and an internally threaded head at its outer end, a nut threaded tor engagement with the spindle and of diameter to pass fi'eely into the cup, a handle member ha ing a threaded stem engaging the internal threads of the cup whereby rotation of the cup is effective to draw the handle member inwardly while outward displacement of the cup is prevented by said nut, and means for locking the cup against rotation after the fitment of the free handle.

2. Door furniture as described in claim 1 further characterized in that the head of the cup is provided with flats by engaging which the cup may be screwed upon the stem of the handle memben. I

3. Door furniture as described in claim 1 further-characterized in that the flanged bottom ofthe cupengages the inner end of the nut whereby the. cup maybe turned while held by the nut against outward movement on the spindle. t

4. Door furniture including in combination a handle having a square section corner threaded spindle arranged to be passed through the door and to emerge in a com centric recess therein, a cup adapted to fit, within said recess having a perforated flanged bottom through which the spindle is passed, said cup being loose onand freely rotatable on said spindle, an internally threaded head at the outer end of the cup, a nut threaded for engage ment with the spindleand of a diameter to pass fieely into the cup thereby enabling the nut to be adjusted on the spindle to restrain axial displacement of the .cup rela tively to the spindle whilst permitting of rotation of the cup thereon, a free handle having a threaded steinfor engagement with the internal threads of the headofthe cup and a squared section recess adapted to fit on the square section spindle so that rotation between the free handle and the spindle is prevented when the free handle is fitted on to the said spindle, whereby rotation. of the cup when the threaded stern of the free handle has been connected with the threaded head of the cup is effective to draw the free handle inwardly whilst outwardly "dis= placement of the cup is prevented by said nut and means for locking the cup against rotation after the fitment of the free handle. y

5}. Door furniture as described in claim 4 further characterized in that the nut and the handle are associated in sliding interlocking relationship so that as the thread; ed stem of the free handle is engaged with the threaded head of the cup the free handle simultaneously; becomes interlocked with the nut to prevent rotation of the nut on the spindle so that during inward movement of the handle the cup is permitted free rotation but is prevented from axial displacement on the spindle since the" nut and :free handle cannot turn .on the spindle.
