Application filed Fabio-i1? 2, 1889. serial No. 225,265,
10 A "T116.0l)j t of this inventimi is to provide a means-fog fastening door-knobs to their lspindls of inexpensive construction, which consists of a, latch carried by the knobslmnk, the lateh'being so formed to he L self se'om'ing,'wh m,in engagement with. the
spindle. g
A further object is to rovicle a construction which admits of cose adjustment to doors varying in thickness over a ('OllSlilOT- 2o able i'enge. s
In the accompanying sheet of drawings which forms part of this.sppliestionFig;ure
i on elevation of two door-knobs and their connecting spindle, embodying" my invention, the shank of one knob being broken away on the line:ll of i 2, Fig. Z'is a transverse section through the shank of one of the knobs on the line 11-31 of Fig. 1.
Each knob A has the usual tubular shank B with a square hole. (lne side of the shank has notch a which cuts through to the square llOlO, The ilGlG'lS engaged by s,
s uere spindle C. One side of the spindle a 01m that portion which comes imdei the notcli in the knob shank lies transverse seri'stions b. A latch D is located. in the notch in the shank, and is pivoted to the shank by a pinjB which lies parallel to the shank, and opposite one side thereof, The
40 formed fi'oni s i i elastic metal strip, ai liioh may bo of 'lsirsss or sleei,*anzl wl'iioli is izloubled back spoil-forth to form three layers. The upperla'yer cis curved so that its outer surface'will lie even with convex surface of so the knob she-11k when the latch is in engagemeat, and the free end serves as a handle for liftingtlie latch. Tliereisolittles aceleftin the notch at the end of the hand e, so that it can be picked out. At the junction between the upper layer and the middle layer (Z an eye is formed which is engaged by the pin. The bottom layers is carried loo-cl:
'nnder the eye, and the outwardly facing flat side under the eye, is provided with serrationsf which engage the serrations in the side of the spindle.
When the latch is lifted, the knob can be freely slid onto the spindle, and set in proper scljnstn'ient, and the knob firmly secured by turning (lowntlie latch. As theports are so constructed that the end of the latch. strip bearing the serrations must be crowded into position, the end will be sprung book as the latch is being turned doml, and-will again spring forward when the latch is i u onin piece, thereby bringing together {he gaging serrations, and holding the latvin What I claim as nimand e to sliI'-3 byliettess Fste'st of she Uni The combination of a knob h bulgii' shank and a notch in the side of the shank, s spindle having trsnsverse sermtions in one side thereof, a latch formed from a fiat elastic metal strip located in the) notch, and provided. with serrations to engage the serrations of the spindle, a pivot connection between the lstol'i' oml shank. persilc-l to the axis oi the shank, the axis of the pivot being located directly over the engaging serrations, and the parts being so som stmcted that the serrations will he brought together by the elasticity of the let-ch, sol) stontislly as described.'
