Abstract
284,374. Medway's Safety Lift Co., Ltd., and Read, A,. A. Oct. 20, 1926. Fastenings for hinged and sliding doors.-A ramp 1 mounted upon the lift cage 2 has means such as a spring 4 for biassing the vamp into its engaging position with a roller-ended gate-engaging lever in the well of the lift, a cam member 5 attached to the ramp engaging a roller 12 on the lift gate 10 as the gate is opened and thereby to move the ramp into its engaging position to unlock the well gate. Instead of the members 5, 12 a pin-and-slot mechanism may be used. The ramp is carried by connected links 3 to which is attached one end of the spring 4. The cam member 5 is pivotally mounted at 13 on the cage 2 and a pin 6 at one engages a slotted member 7 secured to the links 3. When the gate 10 is opened the roller 12 carried thereby is moved into engagement with the curved edge 9 of the cam and then engages in a recess 8.
