The check used in this forni ef my invention may he used. with either form of casing' or lock, since the recess in this case may receive the ball exactly as does the hole ll in the liorn'n'ir case when used With the Jornn of casing shown. in Figs. 3 and in the modiiication the check is spr-.nw pressed, as heretofore desnribed.l an d the mede et operationv is suhstai'itiall5v Vthe saine.
Having' fully described n'iy invention7 what I claim as new, and desire to secure h v Letters Patent, is
l. A check-hold er comprising a case having' a slot for the insertion of the stem of a check and having' an inclined passage intersecting said slot, and a locking device mounted to move in said inclined passage and acted upon hy gravitative force for positive movement in each direction either to engage with er release said check, substantially as described.
2. lin a lock for a niiners car-check7 a hall, a casing liavinga recess therein and provided with an inclined aperture in which the bail. can travel, a tace-plate ter the casing, check locked in the casing' by the ball andnieans for securing the casing te the Body of a mine-car.
in a lock of the character described. a casing having' a recess therein and provided with an inclined aperture, lugs in the casing, a ball. adapted to travel in the inclined aperture et the casing, a check having shoulders and provided With means to permit the hall te support the check, a spring having one end se cured by the lugs and its opposite end bearing against the inserted edge of the check whereby)rr the ball is prevented from accidental displacement oy the vibrations oi' the ear and means for Securing the lock to the body of the car as and for the purpose specied.
