BlCYCLE-HANDLE-BAR CLIP.

SPECIFICATION forming part of Letters Patent No. 583,860, dated June 1, 1897.

A plication filed December 8, 1896. Serial No. 614,959. (No model.)

To (FLU whom it may concern.-

Be it known that I, EUGENE H. OLDS, a citizen of the United States, residing at Fort Wayne, in the county of Allen, in the State of Indiana, have invented certain new and useful Improvements in Bicycle-Handle-Bar Clips; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to improvements in bicycle-handlebar clips specially designed and adapted for wood handle-bars.

The object of my invention is to provide a cheap, simple, and efficient clip for bicycle wood handle-bars having the spring-steel clip rigidly fixed on the supporting-stem to avoid all liability to turn thereon, and thus obviates the necessity for set-screws and other holding devices thereon, has a solid instead of a split thread for the clamping-collar to avoid the usual cutting and injury to the threads, is provided with opposite lateral slits to permit of an adjustment of at least oneeighth of an inch in the diameter of the handle-bar without strain upon the metal, and is so arranged that all strain in rigidly gripping the handle-bar is upon the spring-steel clip and not upon the tubular stem.

My invention comprises a spring-metal clip stamped from a single piece of metal having its head provided with a transverse eye to receive the handle-bar, and upon its lower end a solid screw-threaded portion adapted to receive aclamping-collar and a holding-nut and provided with lateral slits to permit of a limited compression of said clip to conform to the size and contour of the handle-bar.

The principal novel feature of my invention consists in the construction by which an increased centripetal compression of the clip-eye is secured without strain upon the metal.

In the accompanying drawings similar reference-numerals indicate corresponding parts throughout the several views, in which- Figure 1 is a perspective view of my invention with the operative parts arranged in the position they assume when clamping the contained handle-bar. Fig. 2 is a plan of the clamping-collar, showing its general rectangular contour. Fig. 3 is a cross-section of the same, showing the teeth which form a bite on the lower face of the handle-bar and also showing the inclined faces which compress the slitted portions of the clip-head. Fig. 4 is a view in elevation of the tubular stem with the spring-metal clip fixed or brazed thereon. Fig. 5 is a side view of the same, showing the slits in said clip to permit of a greater centripetal compression and adjustment of said clip. I I

The clip 2 is shaped from a single piece of spring-steel and has its ends united and formed into an annular screw-threaded portion 3, which is then brazed or rigidly fixed upon the upper end of the tubular stem 1, of the usual size and construction. The transverse eye 4 of said clip, in which the handle-bar is inserted and secured, has its sides laterally extended from the opposite points 11 near the top of said stem, Fig. ft, to afford a more extended gripping-surface. The clip 2 has two diametrically opposite longitudinal slots 5 opening into the lower portion of said eye 4, and are coincident with corresponding slots in the upper end of said stem 1. \Vhile these slots 5 are not absolutely essential to my invention, their use is preferred to afford an increased contraction or adjustment of said eye by the clamping-collar in gripping the handle-bar. The clip 2 is also provided with thevertical slits 12, four in number, two upon each side of said eye at the lower free edges of its extended sides, Fig. 5, and arranged in approximate alinement with the said screwthreaded portion, whereby the said slitted portions can be subjected to increased centripetal compression in the manner hereinafter described. The collar 7 has a cylindrical base, is adapted to be slipped on said tubular stem 1, over and upon the said threaded portion 3, and is provided upon its upper face with two opposite parallel faces having a plurality of serrations 8, adapted to form a bite upon the handle-bar, and also with the two opposite parallel vertically extended flanges 10, whose inner faces are outwardly flaring to embrace and clamp the clip 2, as shown in Fig. 1. The said flanges lOare providedat each extremity with the inclined gripping-faces 9, having a width equal to that of the said teeth 8 and having a different incline from that of the said flanges, and are adapted to engage and compress the said slitted portions of the clip 2. The nut 6 is internally screw-threaded, adapted to fit the screw-threaded portion 3, is preferably hexagonal, as shown, and is adapted to force the collar 7 upwardly on said stem toward the handle-bar to rigidly lock the same. I

The operation of my invention thus described is obvious, and, briefly stated, is as follows: WVhen the wood handle-bar is placed in position in the clip-eye 4, the collar 7 is slipped on said stem 1 into contact with the cylindrical portion of the clip, with its serrated faces arranged transversely of the clipeye, to form a bite upon the lower face of the handle-bar when the said collar is forced home. The nut 6 is now so adjusted on the stem 1 as to force the collar 7 upwardly toward the handle-bar, thereby forcing the springmetal clip to conform to both the size and contour of the handle-bar in gripping the same,while the teeth 8 slightly enter said handle-bar. Practical tests show that the cliphead will admit of an adjustment of at least one-eighth of an inch in the diameter of the bar. As the said slitted portions 13 of the clip-headare engaged by the corresponding gripping-faces 9, it is obvious that the said slitted portions 13 are adapted for an independent and greater centripetal compression by said collar than that portion of said clip engaged by the flaring flanges 10 without causing any strain upon the metal, which is not the case when the said slits are not employed. In a subsequent application, Serial No. 625,023, I have described and claimed a modified form of my invention in which the said slitted portions 13 are omitted.

Having thus described my invention and the manner of employing the same, what I desire to secure by Letters Patent is 1. In a clip for bicycle handle-bars, the combination of the spring-metal clip 2, slotted as shown, having its lower end screwthreaded and brazed upon a tubular supporting-stem, and having the head thereof longitudinally extended and slitted as described; a clamping-collar 7 having the parallel flanges 10, the serrations S, and the inclined gripping-faces for the purpose specified; and a securing-nut 6 adapted to force the said collar toward the handle-bar for clamping the same, all substantially as described.

2. In a handle-bar clip, the combination of the tubular stem 1; a spring-metal clip 2 rigidly fixed thereon as described having a transverse eye 4 for the handle-bar, and havin g upon its lower portion a screw-thread for the holding-nut and provided with peripheral slits 12 for the purpose specified; and means for rigidly clamping and securing said clip to the handle-bar, substantially as described.

3. In a handle-bar clip the combination of the tubular stem 1 slotted as described; the spring-metal clip 2 having the slot 5, the peripheral slits 12, the screw-threaded portion 3 and the transverse eye 4; the clampingcollar 7 having the holding-teeth 8, the clam ping-flanges 10, and the gripping-faces 9 for the slitted portion of the clip-head; and the holding-nut 6, all substantially as described.

4. In a handle-bar clip, the clip head provided with slitted sections, a clamping-nuthaving two parallel serrated faces for the purpose specified, and the opposite flanges 10 adapted to grip the clip-head and provided with the gripping-faces 9, adapted to impart to the slitted sections of the said clip-head as described an independent and increased centripetal compression for the purpose specified, all constructed and arranged substantially as described.

Signed by me, at Fort \Vayne, Allen county, State of Indiana, this al-th day of December, A. D. 1896.
