HAN DLE-BAR.

SPECIFICATION forming part of Letters Patent No. 729,418, dated May 26, 1903.

Application filed .Tune 30, 1902. Serial No. 113.815. (No model.)

To all whom it may concern.:

Be it known that I, JAMES ROBERTSON, diesinker, a subject of the King of Great Britain and Ireland, and a resident of Glasgow,.Soot land, have invented new and useful improved devices applicable for takingup shock in the handle-bars of cycles and motor-vehicles and to hand-barrowhandles,hammer-handles,and the like, (for which an application for a patent has been filed in Great Britain, No. 25,832, dated the 18th of December, 1901,) of which the following is a specication.

The object of my invention is to provide handle-bars of cycles, dac., with such means for taking up shock as will be comfortable to and not liable to injure the users hands.

The improvement consistsl in fitting over the ends of the handle-bar or handle aspiral or helical spring formed of a metal ribbon or strip of `a concave-convex cross-section, withvthe convex face outward, and in securing the end coils of the grip by fastenings to the bar or handle,while the intermediate coilsare out of contact with the internal bar.

In the accompanying drawings, Figure 1 illustrates the application of my invention to the handle-bar of a cycle. Fig. 2 is a longitudinal section corresponding to Fig. 1.

Fig. 3 is a sectional view, to an enlarged scale,

the devices shown in Fig. 3, and Fig. 6 is anv end view of the securing-cap.

The vspring-strips 1 are coiled spirally, and

y the central coils are larger in diameter than those toward both ends, so that these central coils shall be out o f contact with the central bar 2 when the coiled grip is applied to the latter. Each coil may be made in one piece or in several sectional spiral lengths suitably the handle-bar 2, are held together by a rubber band 8 and inserted within the handle.

The wedge 3 has a central opening at its outer Y end and also a slit 2O across its face, (see Fig. 4,)

while the part 4 has a cross-head 6 extending up into the hollow under side of the part 3. A retaining-cap? is placed on the whole and has a central opening, Fig. 6. The end 12 of the grip is bent into the position shown by dotted lines in Fig. 4, passing through a side opening 11 in the cap, Fig. 6, and lying within the slit20 of the part 3. Upon inserting the screw 9 and rotatingit the two wedge-pieces 3 and 4 will bennoved so as to grasp the inside of the bar strongly by expansion. At

' the same time the grip will be prevented from moving by its downturnedend 12 lying within the slit 11. If desired, the other end of the wire of the grip may be fastened to the bar, as shown at 10, Fig. 1, by a screw; but in allV cases the intermediate coils of the grip are out of contact with the bar 2.

Y "I claim as my invention- 1. A handle for bicycles and the like, consisting of a bar having wound spirally around it a spring-strip of concavo-convex cross-section, With the convex face outward, the ends of the spiral spring being secured to the bar,

-but the intermediate coils being out of con,-

tact with the bar, substantially as described.

2. A spring-rip for a hollow handle, comprising a spiral spring-strip of concave-convexvsection with the convex face/outward, a wedge device within the hollow handle, and a cap having a slot, and the wedge device having a slit in its outer face, substantially'as described.l 4 i In testimony whereof I have signed my name to this specification in the presence of two subscribing'witnesses.

JAMES ROBERTSON.
