Abstract
461,025. Locks. PARKES & SONS, Ltd., J., FRYER, E. C., and BUTTER, F. J. Oct. 25, 1935, No. 29459. [Class 44] The rotary cylinder of a locking-mechanism has sliding slotted plates d, d<1>, which are moved inwards in opposite directions against the force exerted by the spring e, when the key C is inserted. The spring is held between projections d<2>, d<3> on the plates, and a plate f in the cylinder engages stops d<4> to prevent excessive movement. In the modification shown in Figs. 12, 13, the partitions b between the pairs of sliding plates d, d<1> are formed as separate plates and are held in their grooves by the projecting plate f. In a further modification, shoulders are arranged in the slots in the sliding plates to engage shaped ledges on the key which then has straight edges. Specification 422,093 is referred to.
