BICYCLE. 4

SPECIFICATION forming part of Letters Patent No. 520,826, dated June 511894 Application filed September 16,1893. Serial No. 485,652- (No model.)

To all whom it may concern:

Be it known that I, EDWARD D. KING, a citizen of the United States, and a. resident of Milwaukee, in the county of Milwaukee,and in the State of Wisconsin, have invented certam new and useful Improvements in Bicycles; and I do hereby declare that thefollowing is a full, clear, and exact description thereof.

My invention has for its object to provide a bicycle handle bar of that classcapable of be; ing readily adj ustedto raise or lower the extremities without change of elevation at the center, thus enabling a rider of the vehicle to vary his the road or track upon which hetravels, independent of an adjustment of the entire han .dle-bar in a vertical direction; "and said in- Fig. 2, a horizontal section takenon line 2-2 of the succeeding figure, and Fig. 3, a rear elevation first figure.

Referring by letter to thedrawings A represents a tubular head providedwith ashank B for connection with the steering-post of a safety bicycle, and to facilitate fitting the head to a handlebar, I make the same and its shank in two sections, the amount'of frictional contact between said head and the handle-bar being proportionate to theextent of the former in opposite directions from said shank. The sections of the tubular head are herein shown as united at four points by screws 12 engaging ears perforated and tapped ears 0 opposed to each other in pairs on opposite sides of said head adjacent to the extremities of the same. This arrangement of the connecting screws and ears serves to divide the strain on the head and prevent the same from springing at the ends. I

The handle-bar is herein shown as preferably rnade from three tubular sections, and the tubular head is arranged on the central position thereon according to fancy," the character of his riding or thecondition of partly in section on line 3-3 ofthef section 0 flush with the inner ends of the other sections D, E, the latter beingjbrazed or,

the shank B that depends'from the tubular" head A above specified, the block being ofsuch length as to extend through suitable apertures at the juncture of said shank and head' The shank B is provided with exterior screw threads for a portionof its length adjacent to the apertures for the block F and engaging these threads is a nut'H that is run up against said block to lock the latter in engagement with the handle-bar when the latter is rotarily adjusted to bring its extremities to the desired elevation.

While I have shownthe corrugations in the handle-bar and block, I do not wish to be understood as limiting myself thereto, as it may be found possible to omit the same and obtain a lock-of said handle bar in its adjusted position. f

F-iom the foregoing it will be seen that I provide asimple means for varying the elevation of the extremities of abicycle handle-bar at the will of the rider without change in the elevation of the remainder of said bar, and it is also to be observed that there are no delicate parts liable to break or get out of order, and the adjustment is'not only positive but as fine as may be desirable. v

Having now described my invention, what I claim, and desire tosecure by Letters Patent is- 1: A tubular'head provided with a shank for connection with a bicycle steering-post, a-

centrally provided with peripheral corrugations, a block having a concave corrugated face opposed to the corrugations in the handie-bar and provided with astem that fits loose in the head shank, and a nut operative on said head shank atrainst the block, substantially as set forth.

5 3. A tubular head provided with a shank for connection with a bicycle steering-post, a-

handle-bar section rotarily adjustable in the head, other handle-bar sections fast on the extremities of the first flush with said head,a

to friction block opposed to the handle bat-and provided with a stem that fits loose in the head-shank, and a nut operative on said shank against the block, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand,at Milwaukee, in I 5 the county of Milwaukee and State of Wiscousin, in the presence of two witnesses.

EDWARD D. KING.
