Thisinvention'iappertains to brakes, andmore particularly to hand "brakes of the type I generally used -in connection/with railroad rolling stock. x 1 1 I, w :f Oneof'the primary objects of myinven- 'tion is toprovidesa hand brake embodying l anovel operating "drum for exerting-a pull 'on the brake chain or 'rod,1the, drum being 3 so constructed as to obtain desired-leverage in for operating. the brake'chain and forelimi- A ating the useoffltheconventional locking ratchet, wheel and dog, i

i I a Another importantzobject ofmy invention is-the-provi'sion of a hand brakeembodying '7 15 conical shaped operating brake drum prorvided with a spiralgroove 'ext'ending'from I oneend thereof to the other, with an inclined; plane arrangedinpredterminedrelation to the brake drum, the inclined plane slidably' receiving; the goperating yoke; for the pull chain or rod; the yoke being received in the spiral groove, whereby upon turning of the drum-the yokex can be fed from one end of 2 theinclined'plane to the other, theinclined g F plane and the wall of the groove of the drum l'cons'tituting alocking wedge for holding the 1 yoke in its desired adjusted position eliminating the use oftheordinary ratchet Wheel a'nd pawl.-

; Q Another salientobject of my invention is the provision of novel means for mounting the inclined plane and conical winding drum trelativetofone' another, whereby a compact 'andefficient structure will'be had. I

wherein similar reference characters desig ,nate corresponding parts throughout the several. views, the letter A' generally, indicates one form of my improved 1br ake mechanism asillustrated in Figures lllOjBfl) inclusive.

My improved mechanism A comprises a rotatable brake shaft lO rot-atably supported in a horizontal plane by supporting bracket generally indicated by the reference 75 character 11. This bracket is-of a substantially U-shape and includes the upper. and

.lower diverging legs 12 and 13 and the connecting bight portion 14. The terminals of the legs 12 and 13 have formedlthereon the 1 30 attaching ear 15 through which extends the retaining elements 16. These retaining elements 16- extend through the end wall 7 of the railroad car indicated by the reference character C. It is to be noted that the brakes?) shaft 10 likewise rotatably extends-through the end wall 7 of thecar C and through'the bight portlon .14: of the bracket 11. The shaft 10 is arranged closer to the leg 13 than the leg 12, for a purpose, which will be more; 90 fully pointed out, but it is to benotedat this'time that the 1eg13 c on stitutesan i1,
