ADJUSTABLE HANDLE-BAR FOR BICYCLES.
SPECIFICATION forming part of Letters Patent No. 583,105, dated May 25, 1897.
Application tied June 15, 1896.
To (ti/ whom it may concern,.-
Be it known that I, ORRIN A. WHEELER, a citizen of the United States, residing at Chicago, in the county of Oook and State of Illinois, have invented certain new and useful Improvements in Adjustable Handle-Bars for Bicycles, of which the following is a specification.
This invention relates to improvements in handle-bars for bicycles.; and it consists in certain peculiarities of the construction,novel arrangement, and operation of the various parts thereof, as will be hereinafter more i fully set forth and specifically claimed.
The objects of my invention are, first, to provide a handle-bar .which can be readily adjusted to any desired position by a person while mounted and riding the bicycle or when dismounted, and, second, such an adjustable handle-bar in which the handhelds or grasping portions thereof will always remain in the same position relative to the steering-post, or, in other words, said handhelds or grasping portions of the bar will lie in a horizontal plane within the arc described by the pivoted portions of the bar.
Another object of my invention is to provide a handle-bar which shall be made in two sections or pieces and so connected to the .steering-post that either piece may be raised or lowered independently of the other.
In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in which Figure 1 is a View in side elevation of a portion of the steering-post of a bicycle, showing my handle-bar secured thereto and illustrating it by dotted lines in a raised position. Fig. 2 is a front view in elevation of a portion of the steering-post, showing the pieces composing the handle bar secured thereto and illustrating them in a raised position by broken lines. Fig. 3 is an enlarged view, partly in section and partly in elevation, taken on line 3 3 of Fig. 2, showing the manner of adjustably securing the handlebar to the steering-post. Fig. 4 is a view in elevation of the front upper part of the steering-post, showing the slotted and toothed or serrated seats or extensions to which the Serial No. 595,517. (No model.)
pieces of the handle-bar are secured. Fig. 5 is a rear view in elevation of a portion of the lsteering-post, showing the recess in one of the seats or extensions in which the adjustinglever operates. Fig. 6 is a detail view of one of the adjusting-levers detached. Fig. 7 is a like view of the adj listing-lever used on the.
opposite side of the steering-post; and Fig. 8 is a sectional View, taken on line 8 8 of Fig. 5, showing the beveled part of one of the recesses of the extension or seat for one piece or section of the handle-bar.
Similar letters refer to like parts throughout the different views of the drawings.
A represents the steering-post of a bicycle, the upper end of which is provided with lateral extensions or seats B, which are counterparts of one another and are preferably made integral with the steering-post. The seats are usually made cup-shaped, or substantially in the form of a half-sphere, as is clearly shown in Fig..3, and are provided on their front surface or that farthest from the saddle of the bicycle with teeth or serrations b to engage like teeth or serrations c on the ends of the sections C, composing the handle-bar.
On the inner or rear portion of each of the seats or extensions B is formed a recess b', which'is circular, as shown in Fig. 5, toreceive the circular head d of the adjustinglevers D, which are pivotally secured on the bolts E, used for securing the sections of the handle-bar to the seats or extensions on the steering-post.
The seats B are formed with segmental partitions b2 and b3, which extend inwardly, as shown, and form the walls of the recesses b. As seen in Figs. 3 to 5, inclusive, the partitions or Walls b2 and b3 are separated and form a diametrical slot h4, whose central portion is enlarged, as at b5, to admit of the screw-bolt E in each of the seats. The rear surfaces of the iioors b2 and b3 are beveled in opposite directions, as shown in Figs. 5 and 8 of the drawings.
The sections or pieces C,- constituting the handle-bar, are provided at their free ends with handholds or grasping portions C', which are made of any suitable material and of the ordinary or any preferred construction, and are formed or provided' at their other ends with portions O2, which are preferably IOO
