HANDLE-BAR.
SPECIFICATION forming part of Letters Patent No. 560,172, dated May 12, 1896.
Application filed October 11,1895.
To all whom t may concern.-
Be it known that I, ALBERT lnnxiNs, a citizen of the United States, residing at Chicopee, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Handle-Bars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The object of the invention is to provide for varying the height and angle of the handles of bicycles and their distance from the saddle, so that the same machine may be capable of adjustment to suit all riders, no matter what their preference may be in the matter. It is well known that this involves a great range of possible changes. Real and apparent simplicity are both indispensable. No matter how perfect the result, if it be obtained at the expense of strength, or security, or lightness, or convenience, or appearance, or largely increased cost, the devices are a practical failure. Vith these ends and considerations in view the mechanism shown in the accompanying drawings has been devised.
Figure l is a perspective view of the complete handle-bar in a position which it may have when in use. Fig. 2 is an axial section at l 2, Eig. l. Fig. 3 is a section at 3 3, Fig. l, certain parts being slightly separated to show construction and the manner of assembling. Figs. 4 andare detail views. Fig. G is an axial section at G 6, Fig. l.
The one-piece handle-bar A passes through an eye B at the upper end of the usual tubular stem C and is revoluble therein upon its own axis. It may, however, be fixed in any position by means of a nut D engaging a threaded portion E of vthe stem and forcing the teeth F of lugs G upon a collar II into engagement with a milled sleeve I, which is practically a part of the handle-bar, being brazed or otherwise secured thereto. The end planes of the bar A are approximately perpendicular to the axis of its central portion, and to these ends are secured handles J approximately parallel to said planes and capable of rotary adjustment about the axes Serial No. 565,362. (No Inodehl of the end portions of the bar. The sleeve I accurately its the eye B, which it equals in length, and near each end it is milled or otherwise roughened around its whole circumference. Below the eye isa collar II, already mentioned, whose lugs G, diametrically opposite each other, t suitable slots in the eye and by their toothed or otherwise roughened surfaces F engage the surface of the sleeve I. The nut D, which forces the collar toward the han die-bar, is made of considerable thickness, and its lower part is adapted to receive a wrench, whereby the handle-bar may be clamped with any desired degree of force. The parts are so formed that the entire visible surface of the nut, collar, eye, and sleeve is continuous, and the whole is not materially diiterent in appearance from the ordinary non-adjustable parts usually employed at this point.
It is evident that the handles may be clamped in a great variety of positions by the devices just described, and that if the handle-bar be vertically curved a combination of this adjustment with a half-rotation of the stem may change the handle-bar from upward curvature to downward curvature.
The handles J are provided with radiallyserrated end plates J which engage the correspondingly-serrated end faces of the handlebar, and bolts K, passing through the plates into nuts L iixed in the handle-bar, serve to lock the handles in any desired position or at any-point in the whole three hundred and sixty degrees of angular adjustment. From the construction it follows that if the handlebar be rotated to any given position the handles may then be set at any angle, according to the fancy of the rider. The handles may be readily detached, and when either has been removed and the nut upon the stem has been loosened the handle-bar may be slipped out of the eye and thus detached completely from the machine.
Vha-t I claim isl. The combination with a stem having at its upper end a transverse eye, of a handlebar passing through said eye and revoluble therein, a collar encircling the stem and provided with a toothed or roughened surface to IOC engage the handle-bar, and ineens for foreiug said collar toward the handle-bar to look it. 2. The combination with the stein having its lugs against the handle-bar and thus lool; 1o the latter.
In testimony whereof I affix lny signature at its upper end the transverse sleeve or eye in presence of two Witnesses.
5 slotted below upon each side of the stein, o'f the collar sliding upon the stem and provided with roughened lugs fitting the slots in said eye, a handle-bar revoluble in said eye, and means for forcing' the collar upward to bring ALBERT PERKINS. lVitnesses GEORGE W. HADLEY, CHAs. C. CANDY.
