ADJUSTABLE BICYCLE-HANDLE.

SPECIFICATION forming part of Letters Patent No. 587,626, dated August 3, 1897.

Application filed March 2 5, 1897. Serial No. 629,254- (No model.)

To all whom it may concern:

Be it known that I, FRED VOLLMER, a citizen of the United States, residing at Chester,

in the county of Orange and State of New York, have invented new and useful Improvements in Adjustable Bicycle-Handles, of which the following is a specification.

This invention relates to a handle which is capable of adjustment along a handle-bar; and'the invention resides in the novel features of construction set forth in the following specification and claims, and illustrated in the annexed drawings, in whiol1 Figure 1 is a plan view of handles, one shown sectioned. Fig. 2 is a section along x 50, Fig. 1.

The steering-post 1 has the handle-bars 2 projecting therefrom, the free ends of these bars having handles 3, as shown. Sometimes 'a rider wants to place one or both hands on a handle -bar intermediate the steering-post An adjustable handle or handles 4 can be set for this purpose along bars 2 at any point intermediate post 1 and main handles 3.

Each supplementary handle a is hollow for the insertion of a stem 5, carrying a bearing face or block 6. The handle-bar 2 passes between this block 6 and an other bearing-block 7, which latter is tapped for the engagement of screw 8. This screw 8 is shown provided with a stem 9, adapted for the engagement of a key or tool for turning the screw. This screw 8 is of somewhat larger diameter than its stem 0, so that the screw 8 forms a shoulder at its meeting-point with such stem. Sitting snugly about stem 9 and resting on screw part 8 is a filling-block 10, in which said stem 0 can rotate. The blocks 7 and 10, it is understood, are not intended to rotate. This stem 9 projects loosely or rotatively through a perforation at the top or bow part of a yoke or bail 11, jointed to handle 4, as by a pivot 12. \Vhen the screw 8 is rotated to screw out of the tapped block 7, it will carry or press block 10 against bail 11 and press block '7 against handle-bar 2 to grip the latter between blocks 7 and 6, or, in other words, to fix the supplemental handle 4 on the bar 2. A reverse turn of screw-stem 9 "frees bar 2 from the grip of blocks 6 and 7 to enable the handle 4: to be slid or adjusted along bar 2. The swinging or pivoted bearing or yoke enables the handle 4: to pass or be fixed on curved or non-rectilinear parts of the bar 2.

The block 6 is supported by or forms part of the stem 5, and the latter, when made hollow, will not add unnecessarily to the Weight of the device. The block 6, when corrugated at its face contacting with bar 2, can be made to insure a tight grip or prevent the handle 4 slipping accidentally along the bar. The blocks 6 and 7 can be conveniently termed gripping-blocks, as they grip the handlebar" sitting between such blocks. The block 10 may be termed a ffilling-blockjas it fills the space between block '7 or between the shoulder of the screw-stem and the bow or yoke 11. The pivot 12 is shown passed through the handle at and block-stem 5, so as to lock these two parts together or prevent their rotating with respect to one another. lVhen made as a bolt, this pin or pivot 12, with the yoke 11, ispractieally formed with engaging angular or non-circular parts, so as to cause the bolt 12 to rotate as the yoke is swung, thus preventing the nut of this bolt being unscrewed or worked loose by the movements of the yoke. The angular part of the bolt is shown in Fig. 2 at the head end of the bolt, the other end of the bolt being adapted I shouldered screw-stem made to extend or project through the yoke, a second grippingblock tapped for the engagement of the screwstem, and a filling-block seated on the stemshoulder and through which said stem rotatively extends, said filling-block being interposed between the tapped block and the yoke substantially as described.

3. A hollow handle combined with a stem in said handle, a pin or pivot extended through said handle and stem to look the two together, a gripping-block carried by said stem, a swinging yoke on said pivot,a screwstem rotatively extended through said oke, and a second gripping-block actuated by said screw-stem substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses. I

FRED VOLLMER. \Vitnesses: FRANK DURLAND, GEORGE R. VAIL.
