ADJ UkS-TAB LE BICYCLE-HANDLE.

SPECIFICATION forming part of Letters Patent lilo. 525,171, dated August 28, 1894 Application Bled December 22,1893- Serial No. 494,398. (No model.)

^ Handles, of which the following, taken in connection with the accompanying drawings, is

' a full, clear, and exact description.

kThis invention relates to improvements in bicycles, and particularly to adjusting means whereby the handle bar thereof may be adj usted in its elevation to suit the convenience of the rider, and is composed of the several features of construction and operation of parts, all as hereinafter more fully set forth and particularly pointed out in the claims.

In the annexed drawings similar letters of reference denote corresponding parts in all the views, in which- Figure l is a side view showing the upper end of the forward standard of a bicycle frame. Fig. 2 is a vertical sectional View of the same somewhat enlarged, an d Fig. 3 is a vertical section taken atl right angles tothe view in Fig.

2, while Fig. 4 is an enlarged detached view ofI a portion of the handle-bar with its slotted collar fitted thereto.

Referring to the drawings -A- is the front standard, to the upper portion of which is secured the handle-bar-loop O- within which the handle-bar -B- is held. The handle bar -v-'B- is revoluble within the loop O and is provided with the collar -D- which latter is provided with the longitudinal slots -dcut into, or through, said collar, and may be provided only on a portion of the circumference of said collar or they may be cut entirely around the circumference thereof according to the degree of adjustment of the handle bar desired. Either formed integral with, or secured to the standard -A- is a collar, or shouldered portion -F- which may extend entirely around the circumference of theA standard or consists merely of lugs cast or formed on the outer face of said standard.

The upper'end of the standard is provided with a tongue or projection -H- which extends beyond the central line of said standard asufticient degree to cause it to impinge against the handle-bar within the horizontal portion of the loop -O-, or to enter the slots -dof the collar D' previously referred to. When desired the collar -D- may be dispensed with andv a roughened face provided on the bar -B and in that case impingement of the tongue-H- will answer the required purpose, but it is desirable that the slotted collar -D- be used as better security 1s thus afforded against slipping. The upper end of the standard -A-is concave in cross section so as to conform to the contour of the rounded handle-bar.

The lower portion or stem ofthe T-shaped loop -C- is screw-threaded for a portion of its length, and a collar -E- is provided which is movable on the upper portion of the standard, and is provided with inner annular shoulder -eformed so as to provide Van abutment to rest under the shoulder -F- on the said standard, and when the said collar -E- is screwed into its point of greatest elevation it rmly grasps the lower screwthreaded portion of the loop -C- and is held by the annular shoulder -eagainst the corresponding shoulder -F- so that any movement of said collar -E- toward screwing up on said stem of loop -O- will cause said loop -O'- to draw down and carry with it the handle-bar -B- thus forcing the tongue -H- to impinge against the said handle bar or enter one of the slots -dcut in the collar -D and thus hold the said handle-bar firmly locked in any predetermined position in which it may have been set by the operator. It will be noted that the collar -E- with its inner annular shoulder acting in conjunction with the shoulder or shoulders -F- on the standard -A- acts as a lock which will hold the parts in pos-ition as may be desired, andpwill hold said parts rmly enough to prevent rattling or accidental displacement. A shouldered nut -aor equivalent device may be provided so as to enable the operator to firmly grasp the collar -E- to turn the same when desired, but the form of the grasping portion is immaterial, and may be varied to Vsuit the manufacturer. It will also be apparent that the collar -E- may be made to embrace an enlarged portion of the standard, the enlargement commencing at the point where [OO Y the shoulder -F- is shown, and the whole standard thus made in a single piece without the addition of the collar -F- as shown, the essential feature beinga shoulder against which the annular inner shoulder -emay abut to draw the operative parts together to cause the tongue -II to perform its function in holding the bar -B- in its set position.

The operation of my invention is as follows: The handle-bar being provided with the roughened face or collar D at the point where it is embraced by the loop -C-, is inserted in said loop; handle-bar is set in the desired position, and the screw-threaded collar -E- is screwed onto the lower stem of the loop -C- and drawn up thereon sufficientl y far to cause the tongue -H- to enter the slots -0Z- in the collar -D- and the parts will be locked in position, from which they may be released by unscrewing the said collar -E so as to release said tongue from its engagement and the handle bar may be shifted at will, Where it maybe again secured byscrewing up said collar Having described the invention, what is claimed as new is l. In a bicycle, a rigid standard, a tongue extending therefrom, a longitudinally movable handle-bar1oop, a revoluble handle-bar therein, a slotted collar embracing said handle-bar Within said loop, and a lock on the standard adapted to hold said bar-loop in its4 normal position, substantially as shown and described.

2. ln a bicycle, a rigid standard, a tongue 35 extending therefrom, a longitudinally mov able handle-bar1oop thereon, a handle-bar revoluble within said loop a slotted collar on said handle-bar, a fixed shoulder on the standard, a screw-threaded collar embracing said standard and the stem of said bar-loop, and an annular shoulder within said collar, all combined substantially as specified.

3. In a bicycle, a T-shaped bar-loop with its stem movable on the'upper end of the bicycle standard, a rigid projection from said standard Within said bar-loop, a handle-bar revoluble Within said bar-loop, a collar on said handle bar provided with one or more depressions coinciding With said rigid projections on the standard, and a locking de- Vice adapted to interlock with said bar-loop to hold it in its normal position, substantially as specified.

In testimony whereof l have hereunto signed my name, in the presence of two attesting Witnesses, at Louisville,in the count-y of Jefferson, in the State of Kentucky, this 18th day of December, 1893.
