To all whom z't maj/concern:

Be itv known that I', EDWARD J. LoNN a citizen of the UnitedStates, residing at aporte, in the county of Laporte and State ofA Indiana, have invented a new `and useful Improvement in C cle'Parts, of which thev following is a speclcation;

' The term "ttings,- as usedk in the art'of bicycle-construction, signifies'the unions of the frame-forming tubular. bars with the parts, meanin the crank-hanger barrel, the seat-post an l the common practice to make these .,ttings with nipples projecting from the bodies of.

l veryavealnbecause itsstrength is only that of the two thicknesses of metal, namely the tube and the sleeve telescoping it.

The .object of my improvement is to provide a construction 'of fitting `whereby the joint ,shall contain three lthicknesses of metal, namely, the nipple, vthesleeve and the tube, -and thus add greatl toitsfst'rength and consequently to that o theframe.; j In they .accompanyingdrawing," Figure' 1 is Aa View-inselevationfshowing'la crank'- hanger provided `With my improvement;-

being provided .longitudinally with V-shaped recesses 12, to render these ends resiliently 'compressible for facilitating the telescopic .application to themof 'the frame-tubes 13.

the steering-heads.` It is- 'My improvement consists in reducing or 'tapering the outer-end portion of the nipple to form it With a species .of neck l14, of a diameter that will adaptv it to' fit into the end of a tube 13 and presentwasloping shoulder 15 to meet the extremity of the tu'be.y In thisl way I avoid cutting off the end of the nipple to form the square abutting Yshoulder referred to, and inerely reduce the'diameterof l Y i' the nipple leaving all the-metaland the full strength thereof to be lapped by the tubeend. The neck 14 its'or is' clenched'into a depression formed at 1G about the reinforcl ratenteaaun 23,1914.'

ing sleeve ofl a depth to cause the outer surface. of the neck to extend iush with that of the sleeve beyond the Vouter end ofthe dcpression. This depression conforms in shape yto the inner surface ofthe neck 14, thereby` locking the reinforcing sleeve to the nipple.

I By applying a frame-tube 13 telescopically over a sleeve 10, it overlaps the neck 1 4; and abuts against the shoulder 15 to form with the. neck ay flush joint com-posed of the three thicknesses .of metal, namely the sleeve, neck and the tube, vthereby greatly augmenting the strength of the joint and addingv materially to a cycle-frame (of which only .one tubular` bar .these joint-S..4

a reduced--ne'ck-section extendingv from a l sloping vshoulder and fitting yand confined .in'said depression vto 'interlock the `sleeve 'with the nipple,y` said' neck being adapted to enter an end of atube telescopically appliedvto it andls'aid sleeve to abut Aagainst the sloping Shoulder, 'for the pur-poseset fort-h.
