SPECIFICATION forming part of Letters Patent No. 777,335, dated December 13, 1904. Application filed February 20, 1904. Serial No. 194,484. (No model.)
To (7J/Z when?, may concern:
Beit known that I, ROBERT F. MONAHAN, a citizen of the United States, and a resident of Buiialo, in the county oi1 Erie and State ot' New York, have invented a new and Improved Handle-Bar, oi which the following' is a full, clear, and exact description.
My invention relates to vhandle-bars, and niere particularly Ythese adapted for use upon bicycles and the like, and has 'for its principal object the provision of a yielding bar in which the resisting tension may be adjusted.
Reference iste be had to the accompanying drawings, forming a part of this specification, in which similar characters et reference indicate cerresponding parts in all the figures.
Figure 1 is a central vertical longitudinal section through one embodiment of my invention en the line 1 1 et' Fig. o. Fig. 2 is a central horizontal section-therethrough on the line 2 2 oi Fig. 3. Figs. 3, 1, 5, and 6 are respectively transverse sections en the lines 3 3, 4 4:, 5 5, and 6 6 of Fig. 1; and Fig. 7
a perspective view et' the separated heads and clutch mechanism.
10 designates a supporting-sleeve which may be carried, as usual, upon the handlebar post, within which is an internal supportingsleeve 11, separated from the outer sleeve by a spacing-'cellar 12. As the handle-bar and cooperating elements upon each side oil this support are the same, but one will be herein described.
Within the sleeve 11 and just to ene side of the center thereof is situated a head 13, secured in place by a pin 14 extending through it and the supporting-sleeves. Frein this head a stem 15 projects outwardly, and encircling' this is a spiral torsion-spring 16, hav- .ing a bent end 17, serving to retain it against rotation by engagement with a groove 18, extending along one edge and across the inner side ot' the head 13. The opposite end of this spring' surrounds a similar spindle 19, and its bent end enters a greevs 2O in a head 21,whieh .is fastened to the handle-bar B just outside the end et the sleeve 11 by a transverse pin 22. The bar is rotatable on said sleeve and is shown as extending under the external sleeve, the spacing-cellar being et' such thickness as te admit oli this. The spring 1,6 exerts sulicient longitudinal tension upon the harto hold it iirnily upon the support while permitting it to rotate thereon against its torsional resistance. y
Just beyond the head 21 on the opposite side from the end et' the suppertingfsleeve a clutch member, here shown as consisting et' a sleeve 23, having eppesitely-situatcd end projections or teeth 24 24, which pass through longitudinal grooves or openings 25 25 in the periphery oi' the head 21. These projections ceaetwith a companion. clutch member, this being furnished by recesses in the end ei the sleeve 11, leaving' between them teeth 26. The relative width el these clutch recesses and projections is such that the latter are allowed seme rotary movement in the former. To compel the rotation ei' the clutch-sleeve 23 with the bar while permitting lit te move lengi tudinally, it is provided with a Aprojection here shown as consisting et' a screw 27, th readed inte the clutch-sleeve, havingits end passing through a longitudinal slet 28 in the bar. The clutch members are preferably held in engagement by' a spiral compression-spring 29 interposed between the end of the clutchsleeve and a head 30, which may be secured in the handle-bar by a transverse pin 3l.
The operation et' the device is as fellows: The clutch members are se engaged that the .projections upon one are held against ene side et the recesses ei' the other with some torce by the torsion of the spring, the direction being such that the pressure oi the arms of the rider causes it to yield, absorbing vibration and relieving him from the jar. 'Vhen it is desired te adjust the tension er :lierce which eppeses this yield, the clutch members are separated by the outward movement of the sleeve 23 and the spring tension increased er diminished by twisting the handle-bar upon the supperting-sleeve te an angle at which the projections may secure a new engagement with the recesses.
Havingthus described my invention, I claim as new and desire te secure by Letters Patent- 1. A handle-bar comprising a sleeve, a bar rotatable upon the sleeve, a spring within the sleeve secured thereto and tothe bar, teeth IOO upon the end of the sleeve, and a toothed member rotatable with the bar and longitudinally 'movable therein for coaction With the sleevesleeve secured thereto and to the bar, teeth.
upon the end of the sleeve, a toothed member rotatable with the bar and longitudinally movable therein for coaction With the sleeve-teeth, and a Spring normally maintaining the coaction of the teeth.
3. A handle-bar comprising a sleeve, a bar rotatable upon the sleeve, a spring secured to the sleeve, a head fast within the bar, and a clutch member upon the opposite side of the head from the sleeve for coaction with said sleeve.
4. A handle-bar comprising a sleeve, a bar rotatable upon the Sleeve, a Spring Secured to the sleeve, a head fast Within the bar and provided With longitudinal openings, and a clutch member having projections extending through the headopenings and coacting With the sleeve.
5. A handle-bar comprising a sleeve, a bar rotatable upon the sleeve, a Spring secured to the sleeve, a head fast Within the bar, and a clutch member having a side projection eX- tending through the bar and end projections coacting with the sleeve.
6. A handle-bar comprising a sleeve, a bar rotatable upon the sleeve and provided with a longitudinal slot, a spring Within the sleeve secured thereto and to the bar, a clutch member coacting With said sleeve, and a screw eX- tending through the bar-opening and threaded into the clutch member.
In Witness whereof I have signed my name to this specication in thel presence of two Subscribing Witnesses.
ROBERT F. MONAHAN.
