Abstract
Abstract This lockset has a threaded inside sleeve extending out from its central housing, the sleeve enclosing the inside spindle for the lockset. An inside rose and handle assembly is provided, the rose having inward tabs. A nut is threaded onto the sleeve and has spaced openings about its end remote from the housing, the openings each leading to a series of steps in clockwise direction progressively closer to the housing. Each step has a tread and a riser so that when the handle is brought over the spindle and the rose is maneuvered so that the tabs fit into the openings and the rose is turned in a clockwise direction, the tabs will engage the closest riser to the housing that the thickness of the door will permit. Further clockwise turning of the rose will turn the nut and move the nut closer to the housing so that the treads engage the tabs and draw the rose/handle assembly inward to firmly and quickly install the lockset on the door.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
327 words
A lockset adapted to be quickly mounted on doors of different thicknesses comprising: a. a latchbolt retractor housing, b. a latchbolt retractor within said housing, c. an inside sleeve exteriorly threaded and extending longitudinally outward from the housing, d. a nut having interior threads being threaded onto the inside sleeve and having respective ends proximate and remote from the housing, the nut having an outer peripheral surface formed with peripherally spaced cutouts, each cutout comprising an inward opening at the remote end and a pair of steps facing and progressively closer to the proximate end of the nut, the steps from each opening leading in the same peripheral direction of the nut, each of the steps comprising a tread generally formed radial of the nut and a riser following each tread and disposed generally longitudinal of the nut, e. a handle spindle operatively connected to the latchbolt retractor and disposed centrally of the sleeve and extending longitudinally outward thereinside, f. an inside handle assembly comprising: 1. an inside handle having a shank keyed for rotation with the spindle and moveable therealong, 2. an annular rose scalp extending outward from the shank, 3. an annular rose liner being secured within the rose and rotatably secured to the handle and having radially inward tabs spaced about its periphery structured to align with the peripheral openings in the remote end of the nut whereby in installing the lockset on the door, the inside handle assembly may be telescoped over the spindle so that the tabs are received into the openings in the periphery of the nut and the rose may be turned bringing the tabs into engagement with the risers closest to the proximate end of the nut that the width of the door will permit and further turning tightens the nut on the inside sleeve so that the tabs are engaged by the treads preceding the engaged risers to pull the rose scalp and liner snugly against the door.

Claim 3
Dependent Claim
21 words
A lockset as claimed in claim 1 wherein each tread has a hump therein toward the proximate end of the nut.
Claim 4
Dependent Claim
26 words
A lockset as claimed in claim 1 wherein the rose liner is secured to the rose liner between spaced, opposed annular shoulder means on the shank.
Claim 5
Dependent Claim
42 words
A lockset as claimed in claim 1 wherein the nut is U-shaped in radial cross-section so that the nut comprises inner and outer annular walls with an intermediate bight wall and the bight wall is at the remote end of the nut.
Claim 6
Dependent Claim
37 words
A lockset as claimed in claim 4 wherein the openings at the remote end of the nut are formed in the outer annular wall and the bight wall and the steps are in the outer annular wall.
Claim 7
Dependent Claim
22 words
A lockset as claimed in claim 1 wherein the rose liner is a single annular stamping having the tabs struck inward therefrom.
Claim 8
Dependent Claim
76 words
A lockset adapted to be quickly mounted on doors of different thicknesses comprising: a. a latchbolt retractor housing, b. a latchbolt retractor within said housing, c. an inside sleeve exteriorly threaded and extending longitudinally outward from the housing, d. a nut having interior threads being threaded onto the inside sleeve, e. a handle spindle operatively connected to the latchbolt retractor and disposed centrally of the sleeve and extending longitudinally outward, f. an inside handle assembly comprising:
Claim 9

A lockset adapted to be quickly mounted on doors of different thicknesses comprising: a. a latchbolt retractor housing, b. a latchbolt retractor within said housing, c. an inside sleeve exteriorly threaded and extending longitudinally outward from the housing, d. a nut having interior threads being threaded onto the inside sleeve, e. a handle spindle operatively connected to the latchbolt retractor and disposed centrally of the sleeve and extending longitudinally outward, f. an inside handle assembly comprising:
Claim 10
Dependent Claim
94 words
an inside handle keyed for rotation with the spindle and moveable therealong, 2. an annular rose being rotatably secured to the handle with respect thereto, g. connecting means on the rose and the nut to effect mutual engagement at spaced selected positions axial of the nut and rose so that the rose and nut turn together in a rotary direction in which the nut tightens on the sleeve, the connecting means not permitting axial outward movement of rose with respect to the nut when the rose and nut are at one of the positions.
Claim 11
Dependent Claim
94 words
an inside handle keyed for rotation with the spindle and moveable therealong, 2. an annular rose being rotatably secured to the handle with respect thereto, g. connecting means on the rose and the nut to effect mutual engagement at spaced selected positions axial of the nut and rose so that the rose and nut turn together in a rotary direction in which the nut tightens on the sleeve, the connecting means not permitting axial outward movement of rose with respect to the nut when the rose and nut are at one of the positions.
