re al whom/l it May concern/:

Be it known that I, TERRY STAFFORD, a c1tizen of the United States, residing at Topeka,

in the county of Shawnee and State of Kan- 's'as,have invented new'and-u'seful Improve-' ments in Motor-Vehicle Brakes, of whichthe' following is a specification.

M invention pertains to vehicleebrakes'; and 1t contemplates the provision in a motorvehicleofa simple, inex en'sive,and durable brake of the friction-,0 utch t e and one which may be depended onz-to old without damage-inespectlve'of the direction in which reliable in releasing.

3 the vehicle is moving and which is equally The invention w1l1 be fully understood from 'the' following description and claim when the same are read in connection with the accom- 7 panying drawings, forming part of this specication, in' wh ch.

sleeve or tube section-B and provided With an internal longitudinal groove g, receiving the spline b, Fig. 2 whereby it is held securely against turning on the 'said sleeve or tube secon the diametricallyaenlarged portion a of the tionB. It'will be readily apparent from the foregoing that when the-clutch member e is moved outwardly it will cooperate with the member 0 on the wheelD in frictionally holding the said wheel to the sleeve-section B and against rotation. It will also be apparent that on the clutchmember 0 being forced out-, -wardly the result statedwill be attained irree spective of the direction which the wheel D g is turning and without liability of any of the.

parts being am utee; n will further be a 0' parent that thereiis no tendency ofthe ma e member e to bind in the femalemember c, and

hence on the inward-movement of the member e the releaseof the wheel is certain.

-F is a T-lever fulcrumedat the middle of its head on thecasing A and having a comparatively lon arm or stem m. G is a rod connected tot e said arm or stem m and desi ed to be connected with a hand-lever or ot er device (not shown) for, actuating it and H H are irods extending between and connecting the opposite ends of the head of, lever F and-the male members e of the two friction-clutches. i By virtue of this construction great leverage is afforded, and

hence When-the rod G is drawn forwardly the clutch member's e will be owerfully moved outward to. fasten the-whee s D to the sleeves or tube-sections B and hold said wheels against rotation. It will also be appreciated that by graduating the pull on the rod G the wheels D ma be either locked against rotation or retar ed m their rotation, as the exigencies of the case require.

It will be readily gathered from the fore- 5 going that my improved brake entails the addition of but few parts and little Weight to a motor-vehicle and that it is sim le and reliable inoperation and is not like y to be affected by dust, dirty and the like.
