HANDLE-BAR FOR BICYCLES.

SPECIFICATION forming part lof Letters Patent No.l 781,128, dated January 31, 1905.

Application filed July 2,1904.. Serial No. 215,194.

To al?, whom t may concern:

Be it known that I, FRANK J. OALKINs, a citizen of the United States of America, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Handle-Bars for Bicycles, of which the following is a specilication.

This invention relates to handle-bars for bicycles, and has for its object to provide an automatically-adjustable im provement whereby the rider can instantly and easily change and adjust each bar either separately ortogether at will without either having to remove his hands, reduce the speed, or stop the vehicle.'v y

The invention consists in the new and novel constructions and combinationsfof parts for accomplishing the purpose, substantially as hereinafter described and claimed, and illustrated in the accompanying drawings, in

whicl `Sheet 1, Figure 1, is a top or plan view of the handle-bar head embodying my invention. Fig. 2is ahorizontal section of the same. Fig. 3 is aface vieWof the front or name plate. Fig. 4 is a rear. View of the same, showing the locking-cogs. Fig. 5 is 'a detached View of the sliding bolt on which the handle-,bars are pivoted. Fig. 6 is a detached view of the spring which forces the said bolt outward. Sheet 2, Fig. 7 is a front View of the handlebar head, showing the bars in an-elevated position. Fig. 8 is a side elevation of the head. Fig. 9 is avertical section of the head. Figs. l0 and l1 are respectively detached side views of the disk ends of the handle-bars, showing their engaging cogs. Fig. 12 is a vertical section of the front or name plate. -Fig. 13 is a detached view of the bolt that holds the said plate onto the head-piece.

A represents the handle-bar head, having a through which the sliding bolt O is inserted when putting the parts together. The inside face of the plate B has a series of radial cogs Bv at each side of its center and at its outer edge. Y

D and D are the handle-bars, each having perforated disks d CZ. The disk d on bar D? is double or bifurcated to receive the single disk d on bar D. Each of said bars D D' are provided with radial cogs d" d, designed to mesh with the cogs B on the plate B for locking the handle-bars in place in any of the positions they may be placed. The perforation in the disk on bar D is screw-threaded for receiving and holding the screw-threaded part of the i sliding bolt O, whiclrforms the pivotal joint on which the bars are turned in elevating or lowering them. The handle-bars and this boltare capable of lateral movement in the head A for the lpurpose of disengaging the cogs on the bars from the cogs on the front plate B "to their engagement with the said plate and again locking-them. This is readily done without even letting go the hold on the handlcs or reducing the speed or stopping the vehicle.4 It is therefore apparent that this is a very ready means for immediately adjusting the handle-bars to anyV position desired.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In bicycle handle-bars, a head attachable to the handle-bar post, a spring-seat in said head, and a recess for the reception of the pivoted ends of the handle-bars, afront plate attached to the end of the head and havingl a perforation in line with said spring-seat, handle-bars having perforated disks and radial IOOy cogs, radial cogs on the inside face of the said front plate adapted to mesh with the said cogs on the bars, and abolt through the front plate, the bar-disks and extending into the springseat, and a spring in said seat bearing against said bolt, adapted to lock the bars in the head, substantially as described. V

2. In bicycle handle-bars, a head, a perforated front plate attached to the head, radial cogs on the inside face of the said front plate, handle-bars having perforated disks and also provided with radial cogs, a slidable pivotal bolt through the front plate and the bar-disks, and having a screw-threaded portion for securing it in one of the bar-disks, its inner end extending into the said spring seat in the head, and a spring in the head bearing against the bolt, and adapted to be compressed by the rearward movement of the handle-bars for adjusting the handle-bars, substantially as dcscribed.

Signed by me at Toledo, Ohio, this 28th day of June, 1904.

FRANK J. CALKINS.
